▼ The work described in present thesis deals with the
investigation of Sb10Se90-xGex (x = 0, 19, 21, 23, 25, 27) and
Sb10Se65Ge25-yIny (y = 0, 3, 6, 9, 12, 15) glassy alloys for their
physical, structural, thermal and optical properties. The bulk
samples have been prepared by melt quench technique and thin films
by employing thermal evaporation. The addition of Ge and In to Sb
Se and Sb Se Ge base systems respectively brings about
configurational and conformal changes as observed by physical
parameters. These changes have also been evidenced experimentally
in the thermal and optical properties of the Sb Se Ge and Sb Se Ge
In systems.

▼ Projeto de Pós-Graduação/Dissertação apresentado à Universidade Fernando Pessoa como parte dos requisitos para obtenção do grau de Mestre em Medicina Dentária
Introdução: O MTA foi preconizado com o intuito de substituir os materiais
obturadores que não reuniam as características ideias para tratamentos dentários, tais
como retro-obturações e reparação de perfurações radiculares.
Objectivo: Pretende-se com este trabalho analisar e sintetizar a evidência científica
existente sobre o MTA disponível no mercado que reúna o máximo de caraterísticas
químicas e físicas para a prática clínica em Medicina Dentária.
Materiais e Métodos: Foi efetuada uma revisão bibliográfica, entre os meses de Maio
e Junho de 2014, nas bases de dados on-line, Pubmed e Scopus, utilizando a VPN da
FMDUP e da UFP. Recorreu-se também ao repositório da biblioteca da Faculdade de
Ciências da Saúde da UFP. As palavras-chave utilizadas foram "Mineral Trioxide
Aggregate", "Chemical Properties" e "Physical Properties", correlacionadas com o
operador booleano "AND", nos idiomas inglês, português e espanhol. Desta pesquisa
selecionaram-se 24 artigos que vieram a constituir o corpus documental para esta
revisão.
Resultados: Os resultados foram centrados entre algumas caraterísticas Químicas e
Físicas dos MTA's analisados, nomeadamente Constituição Química, pH, Libertação
de Iões Cálcio, Tempo de Presa, Força de Compressão, Solubilidade e Radiopacidade.
Estes valores obtidos foram variando de cimento em cimento e de acordo com a
metodologia adoptada para a sua obtenção.
Conclusão: A Composição Química do MTA e sua relação é extremamente
importante para nós, Médicos Dentistas, com o intuito de perceber o seu
comportamento no ato clínico a executar e ao longo do tempo. Os valores mais
elevados de pH são do MTA Angelus® e White ProRoot® e o de menor valor é do
MTAB®. O que que apresenta maior libertação de iões cálcio é o MTA BIO® e o que
apresenta menor valor é o MTAB®. Concluímos que o MTA BIO® apresenta o menor
tempo de presa e o Fillapex® o maior tempo. O MTA que exibe maior resistência às
forças compressivas é o MTA ProRoot Grey® e o de menor capacidade é o MTA !

▼ Gasoline or diesel fuel sourced from crude oil source is a complex mixture of hundreds of hydrocarbons. It is extremely difficult to simulate for better understanding of the fuel flow and combustion behaviors which are essential to enhance fuel quality and to improve engine performance. To overcome this difficulty, a surrogate fuel, that has fewer compounds and that emulates certain important
physical properties of a target fuel, can be utilized.
The surrogate mixtures for both gasoline and diesel are designed through a computer aided model based technique by our collaborator at Technical University of Denmark (DTU), and their relevant target
properties are predicted. Following the preparation of surrogate blends, target
physical properties of both fuel surrogates are measured according to American Society of Testing and Materials (ASTM) methods using advanced analytical equipment in the Fuel Characterization Laboratory.
For both gasoline and diesel surrogates, the model predictions are found to be in good agreement with the experimental results except for a few reported cases such as the Reid Vapor Pressure (RVP) of gasoline. For such cases, modifications are made to the model in order to improve the predicted results. Therefore, the experimental investigations are found to be extremely essential for improving the assumptions used to define interactions of the hydrocarbons in the mixtures, which in turn enables enhanced predictability of the model.
The developed model, which leads to a property driven product, can be further investigated to prepare new fuel blends and identify suitable renewable additives in a known amount that can aid in designing of future generation of fuels obtained from either conventional crude oil sources or non-conventional sources. Even though this model provides an excellent, fast and reliable opportunity for screening large number of fuel surrogates and optimization of the same, it is extremely important to experimentally verify the final blends and fine-tune them if necessary before their utilization in engine. Also, the measured property values help to improve the accuracy of the property models as well as the assumptions used to develop them.

▼ Abstract At least 30 000 hectares of land has been converted from plantation forest to pasture in the central North Island of New Zealand between 2000 and 2010. When forests are cleared for pasture the soil may undergo changes in soil structure affecting
physical properties. The overall objective of this study was to investigate changes in soil
physical properties in Pumice Soils following land use change from forest to pasture. Two study areas were identified; one near Tokoroa (Maxwell Farms), and one near Taupo (Wairakei Estate). At each study area a series of sites including: plantation pine forest, pasture converted from pine forest 2,3,4 and 5 years ago, and long term (>50 years) dairy, and sheep and beef pasture, were identified, all on Taupo Pumice Soil. Field and laboratory methods included measurement of; penetration resistance, degree of packing, soil dry bulk density, soil hydrophobicity, unsaturated and saturated hydraulic conductivity, soil moisture retention, aggregate stability, particle size distribution, and soil pH. There was increased soil compaction in the A horizon on recently converted sites compared to pine forest sites as evidenced by higher soil dry bulk density, increased penetration resistance, and degree of packing. At the Tokoroa study area the pine forest soil A horizon had a significantly lower dry bulk density ( mean 0.58 g/cm3) ( P < 0.05 ) than any of the pasture sites (mean 0.65 - 0.72 g/cm3). At the Taupo study area only long term dairy (mean 0.78 g/cm3) and the youngest pasture site (3 years since conversion from pine forest) (mean 0.74 g/cm3) had higher (P < 0.05) bulk density than the plantation pine forest soil. At the Tokoroa study area, the penetration resistance and degree of packing in the A horizon of the pine forest site was lower ( P< 0.01 ) than any other site. The degree of packing and penetration resistance at the Taupo study area in the A horizon of the pine forest site was lower ( P< 0.05 ) compared to 3 years old conversion and long term dairy pasture but was not significantly different from pastures converted 4 and 5 years ago. The water repellency of recently converted pastures was higher (P < 0.05) than pine forest at both study areas. Two of the three long-term pasture sites investigated had very low water repellency. The long term pasture sites had markedly higher total available water holding capacity than either the recently converted pastures or the pine forest sites. The pine forest soil water content at 10 kPa (field capacity) and 100 kPa (readily available water) was generally lower than pasture sites. At the Tokoroa study area there was no significant difference in unsaturated hydraulic conductivity between the pine forest soil and any other site. At Taupo the pine forest soil unsaturated hydraulic conductivity was higher (P < 0.05) than the most recent conversion site (3 years old) but not significantly different from other sites. At the Taupo study area none of the land uses had significantly different saturated infiltration rate compared to the pine…

▼ [ES] El pre-tratamiento de los residuos de la agroindustria es una de las etapas más complejas del proceso de conversión de biomasa en bioetanol. Esta etapa consiste basicamente en aplicar tratamientos físicos o químicos a la biomasa con el objetivo de conseguir la hidrolización parcial de los carbohidratos y que ésos se vuelvan más acesibles para la posterior actuación de enzimas y microrganismos. En este sentido, el uso de ultrasonidos de alta intensidad se ha mostrado como una tecnología con un potencial interesante para, en combinación con métodos convencionales, intensificar los procesos de transporte de materia y energía. En el presente estudio se caracterizaron algunos residuos agroindustriales, concretamente el bagazo de yuca, cáscaras de cacahuetes y residuos de alcachofa, como ejemplos de materias potenciales para la producción de bioetanol después del pre-tratamiento ácido, con y sin la aplicación de ultrasonidos. Así, se caracterizaron los diferentes sistemas biomasa/soluciones ácidas de acuerdo con sus propiedades termofísicas (densidad, calor específico, difusividad térmica y conductividad térmica) y comportamiento reológico. Además, se caracterizó el campo acústico generado en cada uno de los diferentes sistemas mediante un método calorimétrico y se establecieron relaciones entre las medidas acústicas y las propiedades termofísicas y reológicas. Posteriormente, se determinaron las cinéticas de liberación de azúcares reductores y totales y los cambios estructurales producidos en las suspensiones consideradas durante los pretratamientos en disoluciones ácidas, realizados con agitación convencional o asistidos por ultrasonidos. Los resultados obtenidos indicaron que las suspensiones con alta concentración de ácido y alto contenido de sólidos presentaron una menor capacidad de transferencia de calor, debido a los valores más altos de calor específico, difusividad térmica, conductividad térmica. Estas mismas suspensiones presentaron también valores más altos de densidad y viscosidad, lo que indica una mayor resistencia al flujo. Esto se atribuye, no solo a la alta viscosidad, sino también a la aparición de un comportamiento reológico no-Newtoniano, como se observó a partir del ajuste del modelo de Herschel-Bulkley. Así, en suspensiones de cáscaras de cachuetes o de bagazo de yuca con concentraciones de sólidos de 8% y 6%, respectivamente, se observó una tensión residual considerable y un comportamiento pseudoplástico. La temperatura también presentó un efecto significativo en las propiedades termofísicas. Aunque el efecto fue menos intenso, el incremento de temperatura facilitó la transferencia de calor y de cantidad de movimiento. Al aumentar las concentraciones de sólidos y ácido en las suspensiones, también se observó una reducción de la intensidad acústica generada durante la sonicación. Lo mismo pasó al realizar las mediciones de temperatura en puntos más lejanos de la punta de la sonda, indicando la atenuación de la energía acústica en el seno de las suspensiones. La eficiencia de conversión de…

▼ Proteins are one of the most abundant biomacromolecules and play important roles in bioactivities within organisms, including key functions in DNA replication, immune system response, metabolic reactions and molecular transportation. Proteins fold into their unique compact three-dimensional structures to precisely perform their functions. Knowledge of proteins on their structures and interactions with other molecules or biomacromolecules is fundamental to understand the mechanism of many diseases. Thus, in this thesis, the focus is on studying the physical properties of proteins, and protein interactions using microfluidic techniques.
Chapter 1 provides a brief introduction to protein stability and identification as well as their interactions. Then, conventional techniques for studying protein systems are reviewed. Moreover, the principles, designs and applications of microfluidic techniques are introduced.
Chapter 2 demonstrates that a microfluidic diffusional sizing device can be employed to study protein interactions with small molecules by measuring the variation of hydrody- namic radius of bovine serum albumin (BSA) in aqueous solution as a function of pH. By simulating the behaviour of folded and unfolded BSA, the relative population of BSA in dif- ferent states can be calculated. In addition, the key residues that regulate the BSA unfolding process are predicted. Furthermore, I utilize a modified microfluidic diffusional sizing device to measure the hydrodynamic radius of Escherichia coli 70S ribosome and study its interactions with antibiotics, such as chloramphenicol.
In Chapter 3, a microfluidic device for protein identification is designed to measure the physical parameters of proteins, including the fluorescence intensities of specific amino acids (tryptophan, tyrosine, lysine) and the hydrodynamic radius of proteins. Thus, proteins can be correctly identified in a single microfluidic device. The results have significant implications in development of effective and efficient techniques for precise protein identification in their native state.
In Chapter 4, the interactions between a membrane protein (aquaporins) and a small regulator protein (calmodulin) are investigated by detecting the changes of their electrophoretic mobility and diffusivity in microfluidic devices. Then the effective charges of aquaporin0 and its complex with calmodulin are calculated. Finally, the selective binding between calmodulin and different types of aquaporins is investigated based on their relative binding affinities.

▼ AIM: to evaluate the flow, working time, setting time, film thickness and solubility of a
novel root canal sealers (MTA Fillapex) in comparison with a zinc oxide-eugenol– based
sealer (Tubli-Seal), epoxy resin-based sealers (AH 26), a calcium hydroxide-based sealer
(Apexit Plus), and a silicone-based sealer (ReokkoSeal Automix).
MATERIALS AND METHODS: ISO 6876/20012 specifications were followed except for the
solubility test. Solubility was measured by the amount of material extracted from the
specimens left in water over 24 hr period. Film thickness was measured as the distance
between weighted glass slides containing a standard quantity of sealer. Flow was
assessed by rate of sealer extrusion through a standard bore diameter, after unit time.
Working time was taken as the point at which flow rate was reduced by 10%. The
indentation test using a modified Gilmore needle was employed to investigate the setting
times.
RESULTS: ReokkoSeal Automix and MTA Fillapex were the least soluble, whilst Tubli-
Seal was the most unstable in water. Also, Tubli-Seal had the highest film thickness. All
sealers showed comparable flow rates. The working time varied from 30 min for MTA
Fillapex to 4 hr for AH 26. The range of setting times recorded was from 64 min for
Tubli-Seal Xpress to more than 5 hr for AH 26.
CONCLUSIONS: MTA Fillapex and RoekoSeal Automix showed the greatest stability in
Solution. The film thickness values in increasing order were: AH26 < Apexit plus =
RoekoSeal Automix < MTA Fillapex < Tubli-Seal Xpress. The flow rates for Tubli-Seal
xpress, AH26, and RoekoSeal Automix are statistically similar, while Apexit plus and
MTA Fillapex are statistically similar. The working times for all sealers were greater than
30 min. AH26 did not set when incubated in volumes sufficient to fill the test matrices.

▼ The work presented in this thesis represents a combination of laboratory and field experiments designed to explain some field observations I made on some coarse sands in South Australia in 1999: that much of the irrigation water and nutrients applied to the sands under drip-irrigation simply passed through the root zone leaving the crops water-stressed shortly after irrigation events. There was clearly only minimal lateral spread of the water in these coarse sands. However, by applying small concentrations of polyacrylamide or ‘PAM’ in the irrigation water, the crops seemed to do better. Furthermore the timing of irrigation events appeared to be more flexible on the PAM-treated
properties. I found this intriguing and saw an opportunity to increase the lateral spread of water in the root zone and thereby increasing the stored volume and residence time of water. By retaining more water in the rootzone, there was potential to save a considerable amount of costly irrigation
water, and also improve crop production and quality. With encouragement from my then employer (Elders Pty Ltd) and from Ciba Specialty Chemicals Australia, I undertook to explore my findings in greater detail and to attempt to explain them based on some ‘hard’ (experimental) evidence. Increasing the lateral spread of water under drippers in coarse-textured soils requires
water to be retained in the root zone for longer periods during irrigation, but the practical methods for doing this are limited to:
• Altering the pore size distribution to create a finer average range of pore sizes, either by compaction or by stabilization of smaller pores using organic matter or additions of clay.
• Reducing the wettability of the soil so that less water can be taken in and the soil never becomes saturated. (This of course risks surface runoff and suboptimal placement of irrigation water).
• Altering the
physical properties of irrigation water (eg. viscosity, surface tension) so that it interacts differently with soil pores and moves through them more slowly.
The aim of the research was therefore to evaluate the potential for some commercially available PAMs to reduce hydraulic conductivity and to increase water retention on some drip-irrigated coarse sandy soils of South Australia and Victoria.
I worked with two commonly available anionic polyacrylamides, designated PAM-1011 and PAM-135, and measured ponded infiltration in laboratory columns of seven different sandy soils from around South Australia and Victoria. I varied the
concentration of the polymer within the range typically used in the field (0, 1 and 10 ppm for PAM-1011; 0, 2.5 and 25 ppm for PAM-135) and I also varied the quality of the irrigation water used to mix the PAM solutions in terms of salinity and sodicity
(distilled water, 10 and 20 mmol(+) salt/L, using either sodium chloride, calcium chloride, or both). I measured the effects of PAM on pore-size distribution of one of the sands (by the water retention characteristic), on water repellence of the soils (by measuring water droplet…

▼ In various propulsion and power systems, modeling of non-ideal fluid flows (fluids that depart from ideal gas behaviour), presents a great challenge. For example, in organic rankine cycle (ORC) turbines, where a part of the expansion process occurs close to the vapour saturation curve, the flow deviates highly from ideal behavior. A branch of fluid dynamics called the Non-ideal compressible fluid dynamics (NICFD) deals with the modeling and analysis of such non ideal fluid flows. As a consequence of the need for accurate thermo-
physical property computation, various models have recently been developed for non ideal flows and a number of libraries are available to accurately predict the thermo-
physical properties. However, the available thermodynamic libraries are often computationally costly since they require solving of complex equations of state (EoS) to obtain thermo-
physical properties. When these libraries are coupled with existing simulation codes, (for example in computational fluid-dynamics), the simulation process is computationally inefficient. This thesis is an endeavor towards enhancing the computational efficiency of the process of thermodynamic property calculation with the use of the Look up table (LUT) approach. The LUT method aims at computing thermodynamic
properties of a fluid with the help of array indexing operations applied on pre calculated or existing thermodynamic tables. These tables are initially obtained from a thermodynamic library FluidProp. A binary search algorithm helps in accurately locating the query point(s) on the thermodynamic domain. A data interpolation algorithm is then used to predict the thermodynamic
properties of interest. The presented LUT method ensures inherently high accuracy with a very small computational cost, as demonstrated later in the thesis. To check the applicability of the LUT method, it is used to obtain the pressure variation across a control volume with subsonic flow conditions. As a second and a much larger application, the LUT tool is coupled with an in house MOC (Method of Characteristics) tool to design the geometry of a supersonic nozzle. A comprehensive analysis of this method is presented by comparing the accuracies and computational cost with the results from FluidProp. Both interpolation methods implemented in the proposed LUT method prove to be computationally efficient and accurate. The method is successfully applied to the MOC tool to design the geometry of the diverging section of a supersonic nozzle.

▼ [ES] El pre-tratamiento de los residuos de la agroindustria es una de las etapas más complejas del proceso de conversión de biomasa en bioetanol. Esta etapa consiste basicamente en aplicar tratamientos físicos o químicos a la biomasa con el objetivo de conseguir la hidrolización parcial de los carbohidratos y que ésos se vuelvan más acesibles para la posterior actuación de enzimas y microrganismos. En este sentido, el uso de ultrasonidos de alta intensidad se ha mostrado como una tecnología con un potencial interesante para, en combinación con métodos convencionales, intensificar los procesos de transporte de materia y energía. En el presente estudio se caracterizaron algunos residuos agroindustriales, concretamente el bagazo de yuca, cáscaras de cacahuetes y residuos de alcachofa, como ejemplos de materias potenciales para la producción de bioetanol después del pre-tratamiento ácido, con y sin la aplicación de ultrasonidos. Así, se caracterizaron los diferentes sistemas biomasa/soluciones ácidas de acuerdo con sus propiedades termofísicas (densidad, calor específico, difusividad térmica y conductividad térmica) y comportamiento reológico. Además, se caracterizó el campo acústico generado en cada uno de los diferentes sistemas mediante un método calorimétrico y se establecieron relaciones entre las medidas acústicas y las propiedades termofísicas y reológicas. Posteriormente, se determinaron las cinéticas de liberación de azúcares reductores y totales y los cambios estructurales producidos en las suspensiones consideradas durante los pretratamientos en disoluciones ácidas, realizados con agitación convencional o asistidos por ultrasonidos. Los resultados obtenidos indicaron que las suspensiones con alta concentración de ácido y alto contenido de sólidos presentaron una menor capacidad de transferencia de calor, debido a los valores más altos de calor específico, difusividad térmica, conductividad térmica. Estas mismas suspensiones presentaron también valores más altos de densidad y viscosidad, lo que indica una mayor resistencia al flujo. Esto se atribuye, no solo a la alta viscosidad, sino también a la aparición de un comportamiento reológico no-Newtoniano, como se observó a partir del ajuste del modelo de Herschel-Bulkley. Así, en suspensiones de cáscaras de cachuetes o de bagazo de yuca con concentraciones de sólidos de 8% y 6%, respectivamente, se observó una tensión residual considerable y un comportamiento pseudoplástico. La temperatura también presentó un efecto significativo en las propiedades termofísicas. Aunque el efecto fue menos intenso, el incremento de temperatura facilitó la transferencia de calor y de cantidad de movimiento. Al aumentar las concentraciones de sólidos y ácido en las suspensiones, también se observó una reducción de la intensidad acústica generada durante la sonicación. Lo mismo pasó al realizar las mediciones de temperatura en puntos más lejanos de la punta de la sonda, indicando la atenuación de la energía acústica en el seno de las suspensiones. La eficiencia de conversión de…

▼ Energy consumption is at an all-time high. However, abundant energy is lost as waste heat. Thermoelectric materials are of interest within the scientific community due to their ability to convert waste heat into useful electricity. Their application is limited though because of low efficiency. Type-I clathrates were discovered as potentially high performing thermoelectric materials after Slack proposed his PGEC (Phonon-Glass-Electron-Crystal) concept in 1995. Type-I clathrates, which are semiconducting caged structures, have remarkably low thermal conductivity due to scattering of phonons by caged atoms which act as rattlers. Ba8Ga16Ge30 has emerged as the leading candidate for clathrates.
Here we investigate the effects of double filling the clathrate cages with lanthanide (Ln) elements along with Ba on the thermoelectric properties of Type-I clathrates with the formula Ba8-xLnxGa16Ge30. Ln elements, La and Eu, have been successfully used as substitute elements. Ba8-xLaxGa16Ge30 and Ba8-xEuxGa16Ge30 have been synthesized successfully. All the compounds have been prepared by solid-state reaction. Powder X-ray diffraction (PXRD) results indicate that the samples are pure phase Type-I clathrates after initial synthesis. Clathrates crystallize in PmA3¯EAn space group. All clathrates were found to be n-type semiconductors. Temperature dependencies of the electrical conductivity, σ, Seebeck coefficient, S, and thermal conductivity, κ, have been measured in the range from 300 K to 850 K for several La and Eu double filled clathrates.
La inclusion causes an increase in the thermoelectric figure-of-merit of up to 8% with Ba7.9La0.1Ga16Ge30 displaying a ZT of 0.66 at 780 K. Eu inclusion causes an increase in figure-of- merit up to 13% with Ba7.8Eu0.2Ga16Ge30 displaying a ZT of 0.69 at 770 K.

▼ Transition metal oxides have attracted growing attention over the last few decades because of rich
physical properties they exhibit. Perovskite structure transition metal oxides AMO₃ are of particular interest to the design of functional materials in modern techniques, since a variety of ways can be used to tune the
physical properties of AMO₃. Single crystals of Y₁₋ₓLaₓTiO₃ are grown by floating zone method to study the magnetic transition from ferromagnetic in YTiO₃ to G-type antiferromagnetic in LaTiO₃. Y₁₋ₓ LaₓTiO₃ shows similar magnetic phase diagram with RTiO₃ family, and the magnetism and the transition temperature can be finely tuned by varying the La doping x. By measuring the change of magnetic transition temperatures on single crystal samples under uniaxial stress, the correlation between the lattice distortions and the cooperative orbital ordering can be distinguished. Double perovskite CaMnTi₂O₆ is the first columnar A-site ordered perovskite exhibiting ferroelectric property. Spark plasma sintering (SPS) is used to successfully synthesize gram-level Ca₂₋ₓMnₓTi₂O₆, which has the same crystal structure and similar high-T [subscript c] ferroelectric property. Through neutron diffraction, the detailed information of the structure is obtained, and the driving force for ferroelectricity is identified. Inspired by the successful synthesis of double perovskite Ca₂₋ₓMnₓTi₂O₆, perovskites La₁₋ₓPrₓRuO₃ are obtained by SPS as well. The substitution of La by smaller rare earth ion Pr gives rise to the crossover from itinerant to localized electronic behavior. A systematical study of
physical properties is made and an unusual second-order metal insulator transition is found in La₁₋ₓPrₓRuO₃. The A²⁺V₂O₄ spinels have the smallest gap caused by electron-electron correlations in the single-valent spinels, and the V-V bond length in these spinels decreases as the A-site cation is replaced by cations in the order of A = Cd, Mn, Fe, Mg, Zn, Co. The density functional theory (DFT) calculation and transport
properties of CoV₂O₄ under pressure indicate that CoV₂O₄ might be at the crossover between localized electron and itinerant electronic behavior. In order to clarify this, the series of AV₂O₄ spinels (A = Cd, Mn, Fe, Mg, Zn, Co) are studied with in situ high-pressure x-ray and neutron diffraction at different temperatures.

▼ High Entropy Alloys (HEAs) are new and promising classes of metallic alloys for structural applications. HEA development is challenging, due to the vast compositional space that exists for these multicomponent alloys. As such, predictive modelling is paramount for the development of HEAs, so alloy design does not need to rely on time-consuming, expensive trial-and-error experimentation. Although solid solution strengthening is the main strengthening mechanism of HEAs, the fundamentals behind this mechanism are not fully understood in this context, and further consideration with respect to modeling is warranted. In this work, the solid solution strengthening mechanism of Face Centered Cubic (FCC) and Body Centered Cubic (BCC) HEAs is investigated experimentally, and the results are interpreted using a combination of different strengthening models available from the literature. Here we show the mechanical behavior of HEAs is comparable to conventional alloys. Similar temperaturedependent yield stress regimes are observed in comparison to conventional BCC alloys, and solid solution strengthening via the contribution of atomic size and elastic modulus mismatch is found to be the main strengthening mechanism. Strength models are used in high-throughput alloy design by combining solid solution strengthening and thermodynamic predictions to find strong, single-phase (e.g. FCC) HEA compositions in the multicomponent space. In addition, a high-throughput experimental methodology for characterizing a large number of HEA compositions is developed. This work contributes to fundamental understanding of solid solution strengthening and phase stability of HEAs, toward the design of promising compositions by prediction that exhibit tailored
properties.

▼ Advanced combustion engine concepts require fuels which are meticulously designed to harness full potential of novel engine technologies. To develop such fuels, better understanding of fuel
properties and their effect on combustion parameters is needed. The investigations reported in this work establishes relationships between several fuel
properties and combustion parameters at engine relevant conditions. Further, these findings along with conclusions from other studies are utilized to synthesize fuels and surrogate fuels with tailored combustion
properties.
This approach of designing fuels relies on constrained non-linear optimization of several combustion
properties simultaneously to design surrogate fuels for transportation fuels to enable combustion simulations. This scheme of fuel design has been devised and presented as Fuel Design Tool in Ahmed et al. Fuel 2015.
Detailed investigations have been made to understand the effect of fuel
properties on the ignition of fuels in Rapid compression machines utilizing a custom built multi-zone model. The study was further extended to explore fuel effects on engine combustion utilizing experiments and modelling to gather understanding of instances of engine knocking and pollutant formation.
Bio-blended fuels allow mitigation of harmful pollutants and also enables engines to operate at higher efficiency. Ignition characteristics of two high octane bio-blended gasolines were studied experimentally in rapid compression machine and shock tube and detailed chemical kinetic analysis was conducted to understand how the presence of biofuels (i.e., ethanol) in gasoline influences the evolution of important radicals controlling ignition.
Another set of biofuels namely methyl acetate and ethyl acetate were studied employing fundamental experimental and computational methods. The investigation involved development and analysis of combustion chemistry models, speciation studies in jet stirred reactors, ignition delay measurements and determination of laminar burning velocities. These fuels are found suited for high performance advanced spark ignition engines and the developed model and analysis will lead to optimization of combustion performance.
The developed fuel design tool along with enhanced understanding of combustion chemistry and fuel
properties enables a complete toolkit ready to be utilized to develop fuels with better suited
properties for the advanced combustion modes.

▼ In this thesis, the influence of moisture on selected physical, compressive and thermal properties of cocoa beans, shea and cashew nut and kernel were studied. Standard methodologies that have been accepted internationally and used by several researchers globally were used for the determination of the selected properties in moisture content ranges normally used for the postharvest processing of the selected crops.
The results of moisture variationon physical properties of cocoa beans and cashew kernels such as 1000-bean mass,true density, porosity, emptying angle of reposeandstatic coefficient of friction showed increasing trends with linear relationships while bulk density decreased linearly for cocoa bean and cashew kernel samples.
The compressive strain and Young’s Modulus for cocoa beans decreasedlinearly with moisture from 0.009 to 0.0045, and 1300 to 205 MPa respectively. However the compressive stress decreased exponentially with increasing moisture content from 1.5 -0.3 MPa while the crushing energy had more positive linear function with moisture content and increased from 0.013 -0.2 J. For shea kernel, compressive stress, compressive strain and Young’s Modulus decreased linearly from 2.0 -0.8MPa, 0.0085 -0.002mm/mm and 2000 –100MPa with increasingmoisture content. Crushing energy increased non-linearly from 0.005 -0.13mJ in the moisture content range of 5% -24% w.b. The compressive stress, strain, and Young’s modulus for the cashew kernel increased from 0.214 -1.214 MPa, 0.355 -0.472 mm/mm, and 2.446 -6.416 MPa respectively as moisture content increased from 5.0 -9.0% wb.
Thermal conductivity increased linearly for groundcocoa beans sample from 0.0243-0.0311 W/oCm and for ground shea kernels from 0.0165 -0.0458 W/oCm in the moisturecontent range of 12.59 -43.84%w.b. at a constant bulk density of 295 kg/m3.Specific heat, thermal conductivity and thermal diffusivity for ground cashew kernel were found to increase linearly from 1586 –1756J/kgº., 0.2103 -0.2296W/mK and 2.369×10-7-2.588×10-7m2/s with increasing moisture content from 5.0 -9.0% w.b.

▼ Biochar (BC) has the potential to be used as container substrates. However, effects of
BC on container-grown plants depend on various factors including container substrate
components mixed with BC, BC percentage and plant type. The purpose of this project is
to test the potential of BC and composts mixes to be used as replacements for the
commercial container substrates.
In the first experiment, mixes of 20%, 40%, 60% or 80% (by vol.) BC with 5%, 10%,
15% or 20% (by vol.) vermicompost (VC) were evaluated as container substrate on basil
(Ocimum basilicum) and tomato (Solanum lycopersicum) plant growth compared to the
commercial peat-based substrate (control). The commercial substrate made up the
remaining volume when the BC and VC did not add up to 100%. Growth index (GI) and
the total dry weight (DW) of basil and tomato in BC:VC mixes were similar to or higher
than the control at 9 weeks after transplanting (WAT). Therefore, the BC (20%, 40%, 60%
or 80%, by vol.) and VC (5%, 10%, 15% or 20%, by vol.) mixes could be used as the
alternative container substrates.
Because of the high price of VC, the lowest VC percentage (5%) from the first
experiment was selected for the second experiment. Chicken manure compost (CM) has
similar fine texture to VC and is cheaper than VC. In the second experiment, mixes with
either CM or VC (5%, by vol.) and BC (60%, 70%, 80% or 90%, by vol.) with the rest
being the commercial substrate were evaluated to grow tomato and basil and compared to
the commercial substrate. At 8 WAT, the GI, shoot DW and fresh weight (FW), and root
and total DW of basil in BC-compost mixes (except 80BC:5CM, 90BC:5VC and
90BC:5CM) were similar to the control, respectively. The GI, stem, root, total DW, and
red and total fruit FW and DW of tomato plants in BC-compost mixes (except 90BC:5CM)
were similar to or higher than the control. Therefore, 60% and 70% BC mixed with as low
as 5% (by vol.) CM and VC can be used to grow basil and tomato plants in containers.

▼ Biomass such as spent grain is difficult to dry when it is in the slurry form. Proposed industrial solutions are to compact wet biomass first and then dry it. Compaction develops desired granular form and increases surface area for drying but also brings new technical challenges. Superheated steam (SS) drying is advantageous over hot-air drying as it is more energy efficient. A problem associated SS drying is the initial condensation leading to disintegration of biomass compacts. The current research investigates the disintegration characteristics of distiller’s spent grain (DSG) compacts while being dried in SS. The study focuses on the DSG flowability, densification characteristics and disintegration behavior of DSG compacts as affected by SS drying conditions, soluble content and particle size distribution (PSD).
DSG fractions with particle sizes from 300 to 850 µm were dried in SS at 150°C and hot-air at 45 and 150°C. Under these drying conditions bulk density and angle of repose (AOR) varied from 0.379 to 0.435 g/cm3 and 46.0 to 50.4°, respectively. The stress-relaxation data obtained during the compaction of DSG at different levels of compressive pressure (60.3-135.7 MPa), initial moisture content (15, 20 and 25% wet basis- wb) and soluble content (15 and 30%) were normalized and analyzed to determine the asymptotic modulus (EA) of the compacts. The highest EA of 174 MPa was obtained for DSG compacts produced with a compressive force of 135.7 MPa, initial moisture of 25% wb and soluble content of 0%.
The percentage increase in volume of DSG compacts during drying in SS at 110 to 150°C temperature range was between 78 to 130%. A comparison between the
physical properties of SS dried and hot-air dried compacts revealed the role of SS in accelerating the release of mechanical energy stored in the compacts. An increase of dimensions and a considerable increase in the hardness and EA of the compacts was obtained by adding up to 70% (w/w) solubles or by decreasing the PSD of wet distiller’s spent grain from d(0.9)=1283.6 to 812.8 µm. This study establishes that compaction of wet biomass followed by SS drying can lead to its effective utilization.

▼ Hempcrete is a particularly promising lightweight, porous, and breathable biocomposite material that has the potential to significantly reduce the embodied energy related to the construction of buildings while improving their indoor air quality. However, hempcrete’s
properties and performance depend on various parameters such as ingredient amounts, binder type, hurd characteristics (e.g., particle size and porosity), and the amount of water. Therefore, there is a great need for research that will focus on the development and production of hempcrete mixes and materials using local, Canadian resources. This research study characterizes the
physical, microstructural, and mechanical
properties of nine hempcrete mixes developed using lime and eco-friendly pozzolans such as metakaolin, crushed brick, and natural hydraulic lime in varying relative proportions. Furthermore, it compares three different types of hempcrete walls against the conventionally insulated walls of a single-story house located in Winnipeg, using S-Timber 2019 software. The microstructure analysis of hurd particles showed their porous nature. The dry densities of all design mix range from 294.59 kg/m3 to 399.68 kg/m3, with the majority (⁓73%) falling between 320 kg/m3 and 370 kg/m3. The average compression strength of the developed samples ranged between 0.11 MPa and 0.51 MPa, whereas the average splitting tensile strength ranged between 0.010 MPa and 0.0348 MPa. The results show a positive correlation between the hempcrete’s mechanical
properties and density, mainly, in the case of compressive strength. The microstructure analysis of all the design mixes exhibit adequate adhesion at the interface, and present high carbonation with some hydrates. The main findings suggest that locally sourced metakaolin and crushed brick are excellent alternatives to the expensive, imported hydraulic lime. The modeling analysis indicates an increase in the dead loads and foundation sizes due to hempcrete infill compared to the base case. The results also indicate that the best option for a house considering the increase in dead loads and foundation sizes, is a wall case that meets the energy code through the thinner wall composed of 100 mm of mineral wool and 140 mm of hempcrete.

▼ The parboiling effect on physicochemical properties of two local varieties of rice (Nerica 1 and
Nerica 2) grown in Ghana was studied by physical and physicochemical analyses during
steaming at three different temperature periods of 100
o
C at 10mins, 110
o
C at 15mins and 120
o
C
at 25mins. The results showed that the effect of parboiling process on the quality indicators
through the kinetic parameters followed the first order kinetic model of initial steps of steaming
and final reaction rate constant values were dependent on steaming temperature and period. Both
Nerica 1 and Nerica 2 showed similar behaviour during steaming process. The Arrhenius-type of
equation described the strong temperature effect on the physical and physicochemical properties
with k-values ranging from 0.188 to 0.530 for lightness; 0.272 to 0.327 for hardness; 0.133 to
0.336 for maximum viscosity; and 0.211 to 0.856 for breakdown value.

▼ The aim of this study is to assess properties of lesser used/known timbers from Mozambique. The studied species were ncurri (Icuria dunensis Wieringa), ntholo (Pseudolachnostylis maprounaefolia Pax), metil (Sterculia appendiculata K. Schum), namuno (Acacia nigrescens Oliv.) and muanga (Pericopsis angolensis Meeuwen).
A comprehensive literature review found the Mozambique timber sector to be dominated by very few hardwood species while the rest of 118 lesser used wood species are almost unexplored. The above mentioned lesser used timbers were selected and subjected to descriptive and comparative analyses aiming at describing the physical-mechanical properties and natural durability with regard to prospective end uses.
Standard test methods determined density, moisture content, dimensional stability characteristics, colour, natural durability and a number of mechanical properties of the selected lesser used timbers. The study revealed that ntholo and ncurri are heavy timbers with a density in the range of 850-1100 kg/m3 and very low dimensional changes. Metil is a medium light wood with an average density of 550 kg/m3 at 12% moisture content and a coefficient of anisotropy of 1.8 from green to oven-dry state. End use assessments suggest that the timbers of ntholo, muanga and namuno can be used in similar applications as the well known timbers, e.g. internal joineries, tool handles and furniture. Metil timber seems suitable for packaging boxes, plywood and construction purposes. In terms of natural durability, the results showed that heartwood of namuno, muanga and ntholo can be classified as very durable to deterioration and degradation caused by fungi and termites. These timbers showed good performance when untreated samples were exposed in- and above ground field tests providing a good indication of the expected service life and outdoor use features. Wood of metil was classified as non durable to any of the considered hazards and is not recommended for exterior uses unless treated with appropriate wood preservatives.
The study determined ntholo timber mechanical properties and examined interrelationships with density and anatomical features of ntholo through regression and correlation analyses. The study found ntholo to be a very dense timber with high mechanical strength in comparison to well known timbers. The regression analyses show that both ntholo sapwood and heartwood densities are poor predictors for the tested mechanical properties, although may provide some indication of tested properties.
All tested properties of ntholo sapwood were influenced mainly by ground tissue proportions, while heartwood properties were described by more leveled anatomical predictors. Fiber length was the only anatomical feature significantly correlated to density and all tested mechanical properties of ntholo. The number of vessels/mm2 and % vessels were not significantly correlated to any of the measured properties but appeared to be key anatomical features for predictions under regression analysis.
The integrated analysis of…

▼ Abstract: New bulk-fill, self-adhering and low shrinkage materials were developed and purposed significant changes in the preconized incremental restorative technique. The aims of this research were: 1) analyze the new composites represented by Tetric EvoCeram Bulk Fill (TEC), Surefil (SDR), Vertise Flow (VF), Filtek Low Shrinkage (SIL) and compare them with the conventional composite Z100 (Z100) in relation to volumetric shrinkage, stress of polymerization, degree of conversion, kinetics, flexural strength and modulus; 2) evaluate depth of cure of different composites and microtensile bond strength of Class II cavities filled by different restorative techniques and materials association submitted to mechanical fatigue-cycling test; and 3) analyze marginal adaptation by scanning electron microscopy (SEM) of Class II restoration before and after mechanical cycling, and ultimate tensile strength. In the charter 1, the volumetric shrinkage was evaluated by mercury dilatometer and bonded-disc techniques (n=5) and stress of polymerization by Bioman instrument (n=5). Degree of conversion was analyzed with NIR-spectroscopy (n=5) and the kinetics by the optical bench (n=5). Flexural strength and modulus were carried out using a three-point bending test after 10 and 60 minutes after photocuring. Results were analyzed by ANOVA and Tukey¿s test (5%). VF showed the highest values of volumetric shrinkage and stresses of polymerization and SIL the lowest ones. SDR obtained the highest rate of polymerization and the highest degree of conversion values. VF presented the highest values of flexural strength in both tested times, and Z100 the highest values of modulus. In the charter 2, Class II occluso-distal cavities (6 x 2 x 4 mm) in extracted human molars were restored using a etch-and-rinse adhesive system ¿ XP Bond (XP) or silorane-based (SSA) associated to TEC, SDR, VF, SIL and Z100 composites placed by incremental (I) or bulk (B) technique. The tested experimental groups were: XP-Z-B, XP-Z-I, SSA-Z-B, SSA-Z-I, XP-TEC-B, XP-TEC-I, XP-SDR-Z100, SSA-SDR-Z100, VF-Z-B e SSA-SIL-B (n=8). Half of the samples were prepared to obtain sticks and submitted to the microtensile bond strength test after 7 days of storage. The other samples were submitted to the mechanical fatigue-cycling test before the microtensile bond strength test. Depth of cure was carried out in restorations with 4.0 mm of depth, removed and submitted to Knoop hardness test (n=3). Results were statistically analyzed by ANOVA and Tukey¿s test (5%). In relation to microtensile bond strength, in overall, XP-SDR-Z showed the highest values in both analyzed surfaces (occlusal and cervical) in cycling and no-cycling groups. The lowest values were exhibited by VF-Z-B in both analyzed surfaces in no-cycling groups and SSA-SDR-Z in cycling groups. In relation to depth of cure, VF obtained the lowest top-to-bottom ratio, while the other tested composites exhibited less than 20% of reduction. In the charter 3, Class II cavities were prepared following the same steps described in…

▼ The aim of this work was to evaluate and model the water absorption process of corn grain submitted to soaking process at different levels of mechanical damage at different temperatures, as well to determinate and model its mechanical behavior during the process. Behavior of some
physical properties was investigated in function of moisture content. Corn grain of AG 1510 variety were utilized, with initial moisture content of 0.142 (decimal d.b.) obtained at a small producer from Viçosa (MG) city area. Different mechanical damage levels were induced at grains, correlating with electrical conductivity. At soaking process, solution of 0.2 % of sulfur dioxide (SO2 ) and 0.55 % of lactic acid (C3H6O3) in distilled water were used, referring to wet milling conventional process of corn grain, at temperatures of (40, 50, 60 and 70) C and mechanical damage levels analyzed indirectly through electrical conductivity of (2.847, 14.077, 22.261, 29.194 and 32.971) μS cm-1 g-1. Soaking process modeling was performed by Pelegs model. Effective diffusivity coefficient to hydration process of corn grain was obtained through observed data adjustment of liquid diffusivity model based on Ficks second law, and its relationship with temperature was described by Arrhenius equation. Bulk and real densities, porosity, circularity, sphericity and volumetric expansion were evaluated to corn grain without induced mechanical damage (witness) in function of moisture content. Mechanical
properties were also determined: force to a specific deformation of 0.001 m, proportional deformity modulus, deformation energy and resilient modulus, evaluating the force-deformation curve, to different moisture content and
physical damage levels. Was concluded, according to obtained results: (a) structural alterations caused by induced mechanical damage at corn grain altered product water absorption rates; (b) Pelegs model adequately adjusted to observed data to entire conditions utilized; (c) effective diffusivity coefficients values increased with temperature and damage level increase, presenting magnitudes between (2.403 × 10-10 and 19.220 × 10-10) m2 s-1; (d) activation energy referred to water diffusivity of corn grain varied from (14.533 to 28.366) kJ mol-1, being that higher values is correlated to higher product
physical integrity; (e) porosity increased linearly until achieve a certain level, and its behavior was described by a bi-segmented model. Bulk and real densities varied by a quadratic relation, where by values decreased until attain a minimal value, increasing afterwards. Circularity and sphericity of corn grain didnt varied with moisture content; (f) Unit volumetric expansion was best represented by Rahmans model. None of the conventional models used to predict volumetric variation of agricultural products adjusted satisfactorily to apparent volumetric expansion observed data of corn grain, therefore a new model was proposed; (g) The mechanical
properties evaluated decreased significantly only with regard to moisture content variation.…

▼ Successful continuous or semi-continuous profile forming of wood-strand composites requires development of the underpinning science, including a suitable binding system, forming defect management, and process-property relationships. A hybrid resin to stabilize the wood-strand preforms for subsequent profile forming and curing was devised using a mixture of poly(vinyl acetate) (PVAc) and phenol formaldehyde (PF) resins. This study examined the influence of PVAc on the cure kinetics of PF with differential scanning calorimetry. Results show that the cure kinetics of PF blended with PVAc does not differ significantly from neat PF resin for blend ratios of 1 or lower. The nth-order Borchardt Daniels model provided good prediction for the curing of adhesive system with a PVAc/PF ratio lower than 1 and neat PF resin. This blended resin system can potentially be used for continuous or semi-continuous profile forming of wood-strand composites.To gain an initial understanding, the complex state of deformations in wood-strand preforms during profiling forming was studied using single-curvature bending. Three failure types were identified based on the primary failure mechanisms in bending, buckling and shear slip. The initial failure in bending was predicted with a strength-based model with the goal of minimizing defects, such as buckling. A relationship between preform conditions, forming defects and thickness recovery was established.Profile-formed wood-strand composites showed much better shape conformance than profiled veneer-based composites. Slow closing rate and relatively high moisture content caused flat and peak-at-core vertical density profiles (VDP). Lower moisture content resulted in more uniform VDP.The internal stress state in the bend of the profile-formed V-specimens was determined with elastic curved beam theory. Delamination, dominated by radial stress, was the initial failure mode. The Chang-Springer failure criterion was used to determine the initiation of delamination failure within the bend of the V-specimens on roller support. V-specimens tested on pin support yielded greater bending strength than those on roller support. These support conditions provide lower and upper bounds for stresses in the bend of the specimen for some applications. This study adds to the limited knowledge base of profile forming of wood-strand composites and provides an insight into process-property relationships.

▼ O sucesso do tratamento endodôntico a longo prazo depende do preparo químico mecânico e também da obturação dos sistemas de canais radiculares, que tem como objetivo prover o preenchimento de forma tridimensional com um material inerte. Um cimento endodôntico ideal deve ser biocompatível, ter tempo de presa adequado, estabilidade dimensional, união à dentina, baixa solubilidade, fácil manuseio e ser radiopaco. Para estabelecer um padrão nas pesquisas de materiais odontológicos algumas especificações são determinadas pela ISO e ANSI/ADA, onde são determinados os testes a serem realizados para cada tipo de material a ser avaliado. O objetivo desse estudo foi avaliar as propriedades físico-químicas de um novo cimento à base de silicato de cálcio tendo como fonte de comparação um cimento à base de resina epóxi. Para a avaliação do pH e liberação de cálcio, tubos de polietileno de 1mm de diâmetro interno e 10 mm de comprimento foram preenchidos com os cimentos e imersos em 10 ml de água deionizada. Após os períodos experimentais de 1, 24, 72 e 168 horas as amostras foram avaliadas quanto ao pH e a liberação de cálcio em um medidor de pH e espectrofotômetro colorimétrico respectivamente. Na análise da radiopacidade, solubilidade e tempo de presa foram confeccionados anéis com 10mm de diâmetro e 1mm de espessura do cimento; o valor da radiopacidade foi determinado de acordo com a densidade radiográfica (mm Al). Para a solubilidade os espécimes foram imersos em 50ml de água destilada por 7 dias, onde foi aferida a massa inicial (antes da imersão) e a final (após a imersão e desumidificação). A avaliação do tempo de presa foi realizada com agulhas Gilmore de 100g e 456,3g. O escoamento foi realizado com base na ISO 6876:2001. Os dados foram analisados por análise de variância e teste de Tukey (P<0,05). Os resultados encontrados nesse estudo, para valores de pH e Ca- foram significativamente maiores para o cimento Biosealer quando comparados ao AH Plus (P<0,05). Nos testes de escoamento, radiopacidade e tempo de presa o cimento biocerâmico demonstrou valores inferiores ao AH Plus (P<0,05). O Biosealer demonstrou uma alta solubilidade comparativamente ao AH Plus (P<0,05). É lícito concluir que, o cimento Biosealer demonstrou boas propriedades físico-químicas tais como; pH, liberação de cálcio, escoamento, radiopacidade e tempo de presa. Essa nova formulação de cimento endodôntico apresentou uma maior solubilidade do que a prevista na ISO 6876:2012.

▼ The south east of Tasmania produces a large proportion of Australian packet salad. Intensive production with frequent cultivation on sandy clay loam soils has resulted in severe erosion, with soil crusting and low irrigation efficiency. Crust formation is common on cultivated soils, occurring in a wide variety of soil types, climates and agricultural practices. Soil crusts form as a thin, dense, low hydraulic conductivity layer on the soil surface that reduces infiltration, increases runoff and restricts seedling emergence. The objective of this study was to: (i) evaluate different approaches for measuring aggregate stability and the severity of soil crusting, (ii) identify mechanisms responsible for aggregate breakdown and crust formation, (iii) identify which soil properties contribute to aggregate stability/instability, (iv) evaluate options for reducing soil crusting, and (v) quantify the physical properties of soil crusts.
Soil samples were collected from 20 sites over five farms all managed for packet salad production. Aggregate stability was measured by rainfall simulation, wet sieving, ultrasonic vibration (dry and moist aggregates) and clay dispersion (dry aggregates). The mechanisms responsible for aggregate breakdown were investigated by comparing the effect of different wetting fluids on dry aggregate stability. Chemical, mineralogical and physical soil characteristics were measured to identify the soil properties related to aggregate stability/instability. The different methods by which aggregate stability were measured were poorly correlated with each other. This suggested that each approach applied a different type of disruptive energy to the aggregates such that the method of assessment needs to be matched to the type by field soils. Aggregate breakdown largely resulted from slaking by clay swelling and raindrop impact, and to a lesser extent clay dispersion and air compression. Aggregate stability determined by rainfall simulation was highly correlated with soil properties that promote aggregation such as the effective cation exchange capacity (ECEC) and the proportion of polyvalent cations, whilst aggregate stability determined by wet sieving was highly correlated with soil properties that promote disaggregation such as sand content and to lesser extent, the proportion monovalent cations especially exchangeable K.
Two experiments were undertaken to evaluate the potential of commercially available products to reduce soil crusting. A preliminary experiment evaluated 11 products, with the four most effective products included in a second experiment. The second experiment compared application of paper waste, gypsum, phosphoric acid and wire mesh, at three different rates and various combinations. Soil chemical and physical properties were monitored over 71 days to understanding how soil crust developed and what changes in soil physical properties occurred over time. Paper waste and gypsum significantly reduced the severity of soil crusting relative to the control. However, these reductions in crusting…

▼ As many of the dairy powders manufactured have to travel long distances to reach their customers, both domestically and internationally, there is considerable interest among dairy powder manufacturers to maintain the quality of their products for relatively long storage periods. Dairy powders can have a long shelf life if packaged and stored properly. Vacuum packaging can be an attractive packaging strategy to maintain the quality of dairy powders and provide added value by improving the efficiency of using the storage space; because of the inherent compactness of these products. Vacuum packaged dry dairy ingredients may also have added ease of handling for end users. However, little is known about the impact of vacuum packaging on the
physical properties of dry dairy ingredients. The main objective of this study was to determine the effect of vacuum packaging over 12 months storage on particle size, particle density, bulk density, tapped density, flowability, compressibility, color, moisture content, surface morphology, and solubility of six types of dairy powders. In addition, the effect of dairy ingredients type was also assessed. Commercial samples of nonfat dry milk powder, whole milk powder, buttermilk powder, milk protein Isolate, whey protein concentrate#80, and sweet whey powder were repackaged in duplicate using multi-wall foil side gusseted bags under varying degrees of vacuum (1, 0.7, 0.4 bar) and a control with no vacuum, then stored for 3, 6, and 12 months at 25°C and 60% relative humidity. Each powder was sampled and analyzed in duplicate for all the above listed quality attributes, upon receiving the powder and after 3, 6, and 12 months of storage.
Moreover, the effect of vacuum packaging on storage space was evaluated comparing three different models; Model (1) represented a 25 kg bag of atmospheric packaged non fat dry milk with the actual dimensions of a commercial 25 kg bag of non fat dry milk. Model (2), a hypothetical model, represented a 25 kg bag of vacuum packaged non fat dry milk with a length and a width equal to those of model (1). Model (3), another hypothetical model, also represented a 25 kg bag of vacuum packaged non fat dry milk with a length equal to half of a pallet width and a width equal to one third of a pallet length, in order to achieve the highest pallet efficiency possible. The pallet used for all three models was considered to be a (48 × 40) pallet. The height of models 2 and 3 was allowed to reflect the bulk reduction effect of vacuum packaging and was determined based on the weight, density and the known dimensions of the bags. It is important to note that the density of models 2 and 3 was assumed to be equal to the density of a small bag of nonfat dry milk. The saved space per bag and pallet efficiency of vacuum packaging and atmospheric packaging were compared using the three models described above.
Physical properties analyses of the dairy powders revealed statistically significant effect of vacuum pressure on only color values: L-, a-, and b but none…
