▼ My PhD research focuses on the recommendation of optimal designs for two-colour microarray experiments. Two-colour microarrays are a technology used to investigate the behaviour of many thousands of genes in a single experiment. This technology has created the potential for making significant advances in the field of bioinformatics. Careful statistical
design is crucial to realize the full potential of microarray technology. My research has focused on the recommendation of designs that are optimal in terms of precision for effects that are of scientific interest, making the most effective use of available resources. Based on statistical efficiency, the optimality criterion used is Pareto optimality. A
design is defined to be Pareto optimal if there is no other
design that leads to equal or greater precision for each effect of scientific interest and strictly greater precision for at least one. My PhD thesis was submitted in June and key aspects of my research are summarised below.
Pareto optimality enables the recommendation of designs that are particularly efficient for the effects that are of scientific interest. I have developed methodology to cater for effects of interest that correspond to contrasts rather than solely considering parameters of the statistical linear model. My approach also caters for additional experimental considerations such as contrasts that are of equal scientific interest. During my PhD, I have provided advice regarding the
design of two-colour microarray experiments aimed at discovering the genetic basis of medical conditions.
For large experiments, it is not feasible to examine all possible designs in an exhaustive search for Pareto optimal designs. I have adapted the multiple objective metaheuristic method of Pareto simulated annealing to the microarray context. The aim of Pareto simulated annealing is to generate an approximation to the set of Pareto optimal designs in a relatively short time. At each iteration, a sample of generating designs is used to explore the
design space in an efficient way. This involves the setting of a number of Pareto simulated annealing parameters and the development of appropriate quality measures. I have developed algorithms to search systematically for the optimal values of the tuning parameters based on Pareto simulated annealing and response surface methodology.

▼ Background: Electronic prescribing systems are designed to aid in the complex process of prescribing by providing patient information and decision support at the point of care. Successful implementation and effectiveness depend on a variety of factors, including usability and user interface design, which influence how the information and decision support are relayed to users. Poorly designed systems have been found to be associated with medication errors.
Methods: We conducted a factorial design study to investigate the impact of screen density, highlighting, and placement of information, on the accuracy of prescribing when using an e-prescribing system. Study sessions were held during clinical pharmacology educational rounds, where residents and medical students answered simulated prescribing scenarios presented on various e-prescribing system interface configurations. Assignment of prescribing scenarios to interface configurations and presentation order were randomized between study sessions. Participants were also asked about their preferences for specific user interface configurations.
Results: A total of 66 participants completed 844 prescribing cases, with 583 (69%) cases answered correctly. The presence of highlighting was associated with correct prescribing decisions (p-value = 0.001), with 181 out of 250 (72.4%) prescribing scenarios answered correctly on interfaces with highlighting of key clinical information, as opposed to 156 out of 242 (64.5%) on interface configurations without. Low screen density and central placement of information were not found to be statistically significant predictors of prescribing accuracy. The presence of highlighting was the only factor that the majority of participants (80.3%) preferred, but no effect was found when comparing prescribing accuracy on preferred versus non-preferred interface configurations.
Conclusions: The factorial design methodology developed is a novel approach for efficient and objective evaluation of multiple user interface design factors in one study. Evidence-based design and usability principles are needed to enhance the design and appropriate use of e-prescribing systems as usability problems continue to be one of the primary reasons for dissatisfaction and poor levels of adoption.

▼ Asphalt’s fatigue and modulus characteristics play an important role in pavement design. Ultimately they govern the required thickness of asphalt to structurally support heavy vehicles. The thickness of the asphalt layer is a major contributor to the cost of construction. In New Zealand, the design of structural asphalt layers has been a problem for some time and gives rise to two areas of concern. First, the present fatigue failure criterion, the Shell fatigue transfer function, which has been adopted from overseas, not only underestimates the fatigue life of the country’s asphalts, but does not accurately characterise the fatigue behaviour of our local asphalt mixes. Consequently, asphalt thicknesses are overdesigned. Second, asphalt’s fatigue behaviour is influenced by numerous factors and therefore can be difficult to characterise. The primary objective of this thesis is to develop fatigue and modulus models, by carrying out fatigue and modulus tests, to characterise the behaviour of two typical New Zealand structural asphalts. Both resilient and stiffness moduli tests were performed at a range of temperatures and loading rates developing moduli master curves, which predict the asphalt’s modulus for any pavement temperature and vehicle speed. A general full factorial experiment was carried out utilising the four-point flexural beam fatigue test. Tests were carried out at different strain levels, temperatures, and loading rates. An analysis of variance showed that the impacts of strain amplitude, temperature, binder type, the interaction of strain amplitude and temperature, and the interaction of strain amplitude and binder type have a significant effect on fatigue behaviour. The developed models, which account for temperature effects give the pavement engineer the ability to undergo a more accurate assessment of fatigue damage than at present for different climatic temperatures demonstrated by using an incremental damage analysis approach. The research shows that with such characterisation for the given pavement’s design life, thinner and less expensive roads can be constructed in New Zealand.

▼ The purpose of this work is to develop an experimental setup with associated mathematical analysis to analyze the changes in diffusivity through calcium alginate gel beads made under different polymerization conditions. The diffusivity of the solutes glucose and tryptophan was calculated by measuring the concentration change over time as solute diffused out of the alginate spheres and into the bulk. The alginate beads were generated using different polymerization conditions following a two-level, three-factor, full-factorial matrix with alginate concentration, cross-linker concentration, and cross-linking time as the factors. The diffusivities showed variations between different conditions, which were analyzed to determine the main effects. No factors or interactions were found to affect the diffusivity of tryptophan. The main effects on glucose diffusivity were the cross-link time and the interaction of alginate concentration and cross-linker concentration. The initial concentration absorbed by the gel matrix showed variation across different polymerization conditions. Statistical analysis was repeated for the initial concentration. Cross-linking time and the interaction between cross-link concentration and time were the main effects on glucose initial concentration, and no factors influenced tryptophan initial concentration.

▼ A hidrofobicidade e a estrutura planar do orbital π estendido de fotossensibilizadores do tipo clorina e hipericina podem favorecer a agregação destes compostos em meio aquoso. Esta agregação pode reduzir a eficiência fotodinâmica e a aplicabilidade destes compostos em diagnósticos e na Terapia fotodinâmica. Uma estratégia para minimizar esta limitação é a modificação destas moléculas pela inserção de grupos hidrofílicos. Neste trabalho foram utilizadas técnicas espectroscópicas para caracterizar as propriedades físico-químicas e fotodinâmicas de derivados de clorina (CHL), e hipericina (HY) obtidos por meio de inserções dos grupos hidrofílicos trizma e glucamina, respectivamente: Clorina-Trizma (CHL-T) e Hipericina Glucamina (HY-G). Os resultados mostraram que estas modificações estruturais aumentaram em até 20% a solubilidade destes compostos em meio aquoso. No entanto, devido à solubilidade parcial dos fotossensibilizadores na ausência de cargas elétricas foram identificados agregados do tipo H em meio ácido, neutro e na presença de íons em solução aquosa. Tais agregados foram solubilizados em meio alcalino e por microambientes micelares dos surfactantes CTAB, SDS e Tween 20. Os agregados do tipo H acarretaram ainda na redução da constante de velocidade de fotobranqueamento e da formação de oxigênio singleto dos fotossensibilizadores em meio aquoso. Contudo, as clorinas foram cerca de 15 vezes mais eficientes do que a hipericinas na geração deste radical citotóxico. A análise sistemática do potencial fotodinâmico dos fotossensibilizadores em células VERO e HUVEC (não tumorais) e HEp-2 (tumoral) foi realizada por meio de um planejamento fatorial combinando-se a concentração, tempo de acumulação do fotossensibilizador no interior da célula e a dose de luz. Esta análise mostrou que o tempo de acumulação do fotossensibilizador é um parâmetro significante para se erradicar seletivamente as células cancerígenas. Ao contrário das células não tumorais, nas células HEp-2 a quantidade de fotossensibilizador acumulado foi proporcional à lipoficilidade dos fotossensibilizadores. A análise quimiométrica resultou ainda em um modelo matemático para a estimativa dos valores da concentração inibitória média que foi validada por meio de comparação estatística com os valores experimentais determinados para os fotossensibilizadores. As hipericinas foram mais fototóxicas para as células tumorais do que as clorinas. Nas células não tumorais os derivados foram menos citotóxicos, sugerindo o uso destes compostos para a inativação seletiva de células tumorais. Todas essas características permitem que os compostos sejam empregados como fotossensibilizadores em diagnósticos e tratamentos fotodinâmicos.
The hydrophobicity and planar structure of π extended orbital of photosensitizers like chlorine and hypericin may favor the aggregation of these compounds in aqueous medium. This aggregation can reduce their photodynamic efficiency and applicability in Photodynamic Therapy and diagnosis. A strategy to minimize this limitation is the…

▼ It is important for a design to be able to discriminate between all pairwise model comparisons when searching for non-zero interactions. If a design does not have this capability, finding non-zero interactions may not be possible. We propose a procedure at analyzing the model discrimination strength when searching for non-zero interactions by understanding the pairwise differenced error sum of squares for a given design. This is done by calculating eigenvalues and eigenvectors of differenced projection matrices which are completely dependent on the design and not the observed values for the response variable. Using this procedure, we have compared two balanced designs and two Placket-Burman (1946) designs which both have n=12 runs, m=5 factors each with 2 levels, and searching over (5¦2)=10 two-factor interaction effects. Additionally, ridge regression and LASSO were used for a model selection approach which both use tuning parameters to calculate the model parameter estimates. All three model selection approaches were used on all four example designs to compare the performance when searching for non-zero interactions.

▼ The ability of natural zeolite and synthetic ion-exchange resin for ammonia removal from aqueous solution was studied through batch experiments. The results showed that both zeolite and ion-exchange resin were effective (up to 87% of removal) in eliminating ammonia from aqueous solution. Factorial design and response surface methodology were applied to evaluate and optimize the effects of pH, dose, contact time, temperature and initial ammonia concentration. Low pH condition was preferred with the optimum pH found to be 6 for both zeolite and ion-exchange resin. High dose generated high removal rate and low exchange capacity. Results of factorial design and response surface methodology showed that temperature was not a significant parameter. The model prediction was in good agreement with observed data (R2 = 0.969 for zeolite and R2 = 0.957 for resin, respectively). For zeolite, the optimum Qe was 22.90 mg/g achieved at pH=7 and initial ammonia concentration of 3000 mg/L. For ion-exchange resin, Qe of 28.78 mg/g was achieved at pH=6 and initial TAN concentration of 3000 mg/L. The reaction kinetics for both of them followed the Pseudo-second order kinetic model (R2=0.998 and R2=0.999, respectively). Equilibrium data were fitted to Langmuir and Freundlich isotherm models with Freundlich model providing a slightly better predication for zeolite (R2=0.992) and Langmuir providing more accurate prediction for ion-exchange resin (R2=0.996). The ion-exchange resin can be completely regenerated by 2N H2SO4.

▼ O glicerol é gerado em grandes quantidades durante a produção de biodiesel e tem se tornado um substrato potencialmente atrativo para a produção bacteriana de produtos de valor agregado, tais como 1,3-Propanodiol (1,3-PD), etanol, hidrogênio e outros. O presente trabalho teve como objetivo a produção de hidrogênio, 1,3-PD e etanol utilizando glicerol residual obtido da síntese do biodiesel. A primeira parte do trabalho visou à produção de hidrogênio utilizando glicerol residual. Nesta etapa, o consórcio microbiano ambiental foi submetido a diferentes tratamentos (ácido, básico, choque térmico, congelamento e descongelamento e dessecação). Os resultados mostraram que a maior produção de hidrogênio ocorreu com o consórcio tratado com dessecação e choque térmico, com produções de 34,2 % mol e 27,3 % mol, respectivamente. A otimização da produção de hidrogênio foi realizada utilizando planejamento experimental e alcançou uma produção máxima de 45 % mol. A próxima etapa do projeto foi isolar as bactérias presentes no consórcio microbiano ambiental. Experimentos em biorreatores foram realizados utilizando glicerol puro e glicerol residual e os resultados mostraram que houve a completa degradação do glicerol pelas bactérias do consórcio e também a produção de 1,3-PD, hidrogênio e ácidos. Nesta etapa, 32 bactérias foram isoladas e testadas para a produção de bioprodutos em experimentos em aerobiose e anaerobiose. Quatro bactérias foram selecionadas e o seqüenciamento do gene foi identificado por 16S rRNA identificou três dos isolados como Klebsiella pneumoniae e um isolado como Pantoea agglomerans. Dentre as quatro bactérias, uma cepa, nomeada como K. pneumoniae BLh-1, foi selecionada para os trabalhos posteriores. Para otimização das condições de cultivo, utilizou-se a seleção de variáveis através do delineamento experimental Plackett Burman (P-B) avaliando a produção de 1,3-PD. Sete variáveis foram estatisticamente significativas e um novo planejamento fracionário 27-3 foi realizado com a finalidade de otimizar o meio de produção. Experimentos em biorreatores mostraram que a produção em bioreator com pH controlado com o meio otimizado no planejamento alcançou uma produção máxima de 23,80 g/L de 1,3-PD com produção de 12,30 g/L de etanol. Os ensaios com alimentação de glicerol residual mostraram que altas taxas de alimentação causam acúmulo de glicerol e diminuem a produtividade de 1,3-PD e etanol. Os estudos utilizando fluorescência 2D e modelo quimiométrico foram aplicados para avaliar as mudanças metabólicas nos cultivos aeróbios e anaeróbios. Os resultados mostraram que houve diferença nas regiões de NADH e riboflavinas ambas associadas ao metabolismo do microorganismo.
Glycerol is generated in large amounts during biodiesel production and it is becoming a potentially attractive substrate for bacterial production for value-added products such as 1,3-propanediol (1,3-PD), ethanol, hydrogen, among others. This work aimed at studying the production of hydrogen, 1,3-PD and ethanol using the raw glycerol obtained by…

▼ Cell culture of chondrocytes, either in an experimental or industrial setting, typically rely on an invariant feeding strategy. The contribution of each component of the total expansion regime to the behaviour of the cells been expanded are not fully understood. It can be argued that to fully realise the potential of cell-based therapies, the exact contribution of the various expansion parameters to growth rate, metabolic behaviour and cell phenotype need to be intimately understood. The studies in this thesis aim to better inform the nutritional aspects of future cell manufacturing strategy by; uncovering the contribution of critical culture parameters to growth rate and phenotype, understanding the relationship of any interactions that may exist between components and how these components may influence the culture as a function of time. Results from the various studies demonstrated that an isolated subpopulation of chondrocytes can be sustained under serum-free conditions that promote SOX-9 transcript expression while returning growth rates similar to that found using serum-based medium. The contribution of the medium components, seed density and adhesion protein concentration to growth rate, metabolic behaviour and SOX-9,6 & 5 transcript expression were quantified using a statistically designed experiment. Two factors from the experiment, EGF and FGF-2, were taken forward and their effects on growth rate and gene expression as a function of time were investigated. The findings revealed that the exact timing of the introduction of the proteins into the culture medium had a marked impact on cell growth and gene expression.

Torasemid je diuretik Henleove petlje sa sličnim
dejstvom kao furosemid. Koristi se u stanjima edema udruženim sa
srčanom bolešću, uključujući i plućni edem, kao i u slučajevima
oboljenja bubrega i jetre. Takoñe se koristi u tretmanu
hipertenzije, samostalno ili u kombinaciji sa drugim
antihipertenzivima. Torasemid ostvaruje dejstvo u uzlaznom, debljem
kraku Henleove petlje inhibirajući tubularnu reapsorpciju natrijuma
(Na+) i hlora (Cl-) ograničavanjem natrijum/hlorid/kalijum
prenosnog sistema. U kontroli kvaliteta farmaceutskih proizvoda
testovi identifikacije i odreñivanja sadržaja aktivne supstance i
nečistoća su veoma važni sa ciljem da se obezbedi visok kvalitet
proizvoda, bez promena u hemijskim, farmakološkim ili toksikološkim
karakteristikama. Prema ICH smernicama, sve nečistoće prisutne u
farmaceutskom doziranom obliku u količini većoj od 0.1% moraju se
ispitati. Za istovremeno odreñivanje torasemida i njegovih
nečistoća razvijene su nove, osetljive i pouzdane HPLC/UV i HPLC/MS
metode. Kompletno hromatografsko ponašanje ispitivanih supstanci i
pronalaženje optimalnih hromatografskih uslova ostvareno je uz
upotrebu eksperimentalnog dizajna. Frakcioni faktorski dizajn je
korišćen za izbor varijabli koji značajno utiču na hromatografsko
razdvajanje. Puni faktorski dizajn je korišćen za optimizaciju tih
varijabli kako bi se postiglo zadovoljavajuće razdvajanje izmeñu
ispitivanih supstanci u najkraćem mogućem vremenu trajanja analize.
Nakon toga, obe metode su uspešno validirane u skladu sa ICH
smernicama i primenjene za ispitivanje farmaceutskog doziranog
oblika, torasemid tableta. Kako u literaturi postoji nedostatak
informacija o degradacionom mehanizmu torasemida, to su aktivna
farmaceutska supstanca torasemid i farmaceutski dozirani oblik
(torasemid tablete) podvrgnuti studijama forsirane degradacije sa
ciljem da se identifikuju potencijalni degradacioni proizvodi i
ustanovi mogući degradacioni put i sveukupna stabilnost torasemida.
Studija je sprovedena u skladu sa ICH smernicama, a uzorci su
izlagani uslovima hidrolize (kisele, bazne i neutralne),
oksidacije, fotolize i termalne degradacije. Za karakterizaciju
nastalih degradacionih proizvoda primenjene su HPLC/UV i HPLC/MSn
tehnike. Kvadrupolni i jonski trap maseni analizatori su korišćeni
da se ustanovi način fragmentacije degradacionih
proizvoda...

▼ In this study, revegetation of plants (Bagasse, Miscanthus floridulus and Eichhornia crassipes) was assessed to be starting as materials for producing bioethanol. The method of full
factorial experimental
design is used to explore different parameters on conversion rates for hydrolysis reaction of fiber into fermentation sugars and analysis the influence of the reaction temperature, hydrolysis time, solvent volume, dilute sulfuric acid concentration and plant species on fermentation sugars. The hydrolysis reduces the effect of improving the reaction time by using the microwave system with absorbing materials. The fibers were observed the residue surface and structural changes after hydrolysis from the X-ray Diffractometer (XRD), Fourier Transform Infrared Spectrometry (FTIR) and Environment Scanning Electron Micrograph (ESEM). Therefore, it can be proved that the increase in saccharification rate can lead to the impact in destroyed and reduce of the cellulose structure presents.
The result shows that the order of effect for reaction temperature, hydrolysis time, dilute sulfuric acid concentration and solvent volume for fiber of water hyacinth was investigated by the method of full
factorial experimental
design under the operational condition of 100â reaction temperature, 30 min hydrolysis time, 30 mL solvent volume and 3% dilute sulfuric acid concentration. Using the bagasse, miscanthus and mater hyacinth as the raw material, the best operational condition for optimal sugar concentration was about 6520 mg/L, 5680 mg/L and 4650 mg/L. The saccharification rate was about 19.58%, 17.05% and 13.94%. Comparing with these three raw materials, sugar crops bagasse has the best effect. From the analysis of the ESEM, XRD and FTIR, the cellulose will increase as the change of saccharification rate. And it can effectively enhance the saccharification rate and reduce approximately 32% to 40% of reaction time by microwave system with nanoscale iron oxide absorbing materials.

▼ As InstituiÃÃes de Ensino Superior sÃo responsÃveis pela produÃÃo de conhecimento cientÃfico, tecnolÃgico e formaÃÃo de opiniÃo. PorÃm, sÃo tambÃm geradoras de uma grande variedade de resÃduos. O uso de resÃduos agroindustriais na remoÃÃo de metais de efluentes à uma alternativa promissora em relaÃÃo Ãs tecnologias existentes. Neste trabalho foram estudadas as propriedades adsorventes do pseudofruto do cajueiro (Anacardium occidentale L.) e o desenvolvimento de metodologias de seu uso no tratamento do resÃduo de Mohr gerado nos laboratÃrios de ensino do departamento de QuÃmica AnalÃtica e FÃsico-QuÃmica da Universidade Federal do CearÃ. Foi estudado o sistema de adsorÃÃo em batelada. Os ensaios preliminares mostraram que o pà do caju à viÃvel na adsorÃÃo de cromo. Foram testadas quatro soluÃÃes para dessorÃÃo, sendo o EDTA 0,05 mol/L o melhor dessorvente. Foram avaliados os efeitos do pH (5,0 e 7,0), secagem â S (estufa e liofilizado), tamanho de partÃcula â P (0,10 â 0,25 e 0,25 â 0,84 mm), massa de adsorvente â m (1,0 e 1,5 g), concentraÃÃo de cromo â C (500 e 1000 mg/L), tempo â t (1 e 3 h) e velocidade de agitaÃÃo â v (0 e 150 rpm), na adsorÃÃo atravÃs de planejamento fatorial fracionÃrio 2^(7-4). Um segundo planejamento fatorial (2^(4-1)) foi realizado para otimizaÃÃo. Neste planejamento as variÃveis foram m (1,0, 2,0 e 3,0 g), C (500, 750 e 1000 mg/L), t (1, 2 e 3 h) e v (0, 150 e 300 rpm), e os parÃmetros fixos pH (7,0), S (estufa) e P (0,25 â 0,84 mm). As regiÃes de mÃxima adsorÃÃo foram mapeadas por grÃficos de contorno. A adsorÃÃo à mÃxima em valores intermediÃrios de m, valores menores de C e valores maiores de t e v. Foi feita a caracterizaÃÃo do adsorvente por infravermelho e fluorescÃncia de raios-X. Para melhor entendimento do mecanismo de adsorÃÃo foram feitos testes de reaÃÃo do cromo com extrato aquoso do adsorvente e monitoramento do pH durante a adsorÃÃo. O mecanismo proposto consiste em duas etapas: reduÃÃo do Cr(VI) em soluÃÃo ou em contato com a superfÃcie; e posterior adsorÃÃo do Cr(III) por troca iÃnica ou complexaÃÃo. Foram estimados parÃmetros de isoterma e cinÃtica com os dados do planejamento 2^(4-1). O modelo de Langmuir foi o mais adequado e a cinÃtica de pseudo-segunda ordem. O tratamento do resÃduo de Mohr promoveu 89,18% de adsorÃÃo de cromo total. O restante do cromo em soluÃÃo (10,82%) ficou na forma de Cr(III), menos tÃxico. Na etapa de dessorÃÃo com EDTA 0,05 mol/L, 33,40% do cromo foi recuperado. Foram propostas alternativas de reutilizaÃÃo do resÃduo em atividades de ensino.
The Higher Education Institutions are responsible for the production of scientific and technological knowledge, and opinion formation. However, they also generate a variety of wastes. The use of agro-industrial wastes in the removal of metals from wastewater is a promising alternative to existing technologies. In this work, the adsorptive properties of cashew pseudo-fruit (Anacardium occidentale L.) were studied and a method was developed for its use in the treatment of Mohr residue generated in…

▼ In today's fiercely competitive marketplace, successful and profitable companies
distinguish themselves by bringing new products to market before their competitors. The
cycle time to develop and launch new products largely depends on a company's ability to
study large numbers of factors and to separate, or detect, the significant factors from the
insignificant factors. Most ordinary experimental situations with many variables are easily
satisfied with the use of a saturated, or nearly-saturated, fractional
factorial experimental
designs. However, there are occasions where the cost of mnning a statistically designed
experiment can be so great as to prohibit the use of these techniques, forcing the
experimenter to resort to other, riskier, experimental techniques.
Theory suggests that a relatively new class of designs, systematic supersaturated
designs, may prove to be even more effective at identifying significant factors than
saturated, or nearly-saturated, fractional
factorial designs. For the purpose of continuous
improvement in the monetary and cycle time expenditures for new product
design, new
process launch, and new manufacturing process launch, supersaturated designs may
provide the experimenter with a viable solution to the problem of studying more factors
than permitted in a saturated
design.
Although, much has been written about creating supersaturated designs, little has
been written regarding the analysis of these designs. This paper examines three test
statistics which one might consider using when analyzing a supersaturated
design. These
test statistics are studied for four different supersaturated designs. The simulations and
mathematical justifications presented in this paper suggest that it is not in the best interest
of the experimenter to use these test statistics with these designs on a regular basis.

▼ Devido a sua composição bioquímica, as microalgas apresentam o potencial de serem
adicionadas diretamente a alimentos e ração animal, ou indiretamente por meio da
adição dos biocompostos produzidos pelas mesmas. Além disso podem ser utilizadas
na biofixação de CO2 e na produção de biocombustíveis. O objetivo deste trabalho foi
produzir biomassa e ácidos graxos por diferentes microalgas e condições de cultivo.
Para o desenvolvimento do trabalho, este foi dividido em três etapas: (i) avaliação da
influência da atenuação da intensidade luminosa na produção e composição da
microalga Tetraselmis suecica F&M-M33; (ii) avaliação do crescimento e produção de
ácidos graxos pela microalga Nannochloropsis oculata em cultivos autotróficos e
mixotróficos; e (iii) avaliação do crescimento e produção de ácidos graxos pelas
microalgas Chlorella vulgaris e Chlorella kessleri em cultivos autotróficos e
mixotróficos. No cultivo da microalga T. suecica F&M-M33 a produtividade foi
influenciada pela concentração celular mantida nos cultivos bem como pela radiação
solar incidida. Quando os ensaios foram realizados em fotobiorreatores inclinados,
estes apresentaram produtividade máxima de 0,96 g.L-1
.d-1
. Quando realizados em
GWP verticais, dispostos paralelamente, a produtividade máxima obtida foi 0,45 g.L-
1
.d-1
. As máximas concentrações proteicas (49,87 a 51,01%) e lipídicas (22,03 a
23,36%) foram obtidas quando a microalga foi cultivada nos fotobiorreatores verticais e
dispostos paralelamente sem interferência de sombreamento nas laterais. Para a
microalga N. oculata foram realizados 2 planejamentos fatoriais 2
3
, em que foram
variadas a temperatura, concentração de nitrato no meio de cultivo e fonte de carbono.
Os máximos valores para o crescimento celular e produtividade foram obtidos no
cultivo mixotrófico (0,64 g.L-1
e 141,95 mg.L-1
.d-1
, respectivamente), quando a
microalga N. oculata foi cultivada em meio F/2 utilizando 1 g.L-1
de glicose como fonte
orgânica de carbono, 75 mg.L-1
de NO3 e 20 ºC. Para o cultivo autotrófico as máximas
concentração celular e produtividade (0,62 g.L-1
e 69,78 mg.L-1
.d-1
, respectivamente)
foram obtidas quando a microalga foi cultivada com 1 g.L-1
de NaHCO3, 10 mg.L-1
de
NO3 e 20 ºC. Os principais ácidos graxos encontrados em ambos os cultivos foram o
ácido mirístico (C14:0), ácido palmítico (C16:0), ácido palmitoleico (C16:1), ácido
oleico (C18:1) e ácido eicosapentaenoico (EPA, C20:5-3), destacando-se o ácido
palmítico (C16:0) que apresentou concentrações de 21,4 a 47% do total dos ácidos
graxos analisados. As microalgas Os cultivos das microalgas C. vulgaris e C. kessleri
foram avaliados utilizando metodologia de Planejamento Experimental Plackett
Burman. A microalga C. vulgaris apresentou concentração celular máxima (0,97 g.L-1
)
no cultivo autotrófico, com fotoperíodo 24 h claro e 6% de CO2. A máxima
produtividade (180,68 mg.L-1
.d-1
) foi obtida no cultivo mixotrófico para C. vulgaris
cultivada com 1 g.L-1
de NaHCO3 e 5 g.L-1
de resíduo industrial de oleaginosas (RIO).

▼ Abstract: The production of fructooligosaccharides (FOS) - a prebiotic sugar with wide industrial application - from immobilized enzymes includes two modern concepts: industrial application of immobilized enzymes and functional food. A strain isolated from flowers from the Brazilian Atlantic Forest identified as Rhodotorula sp. LEB-V10 showed great potential for production of the extracellular fructosyltransferase (FTase), which is capable of producing FOS from sucrose. It can be recovered only by precipitation with ethanol (partial purification), directly from the cell-free culture medium. According to previous studies, the kinetics between purified and partially purified immobilized enzymes showed no significant differences that could justify additional purification steps. Other previous studies have selected the adsorption on particles of a solid-acid support (Nb) an alloy consisting of niobium (~95%) and graphite (~5%) as suggested methodology for the immobilization of FTase for FOS production. Thus, this work presents a series of characterization studies of this immobilized biocatalyst. After the immobilization, it was observed that besides the pH of maximum activity presented by the free enzyme (pH 4.5), a second distinct point of maximum activity (25% lower than at pH 4.5) was also observed, pH 6.0, wich was proved to be the best condition for thermal stability and also better for synthesis with the immobilized enzyme than pH 4.5. The study of thermal stability has also shown that immobilization induces the formation of two distinct phases with different denaturation activation energy (Ead): between 47 and 51°C, the immobilized enzyme is more stable than the free enzyme, and between 52 and 70°C it is less stable. Incubation of free and immobilized FTase at 52°C for 15 min resulted in enzymatic activation, being more pronounced with the immobilized enzyme at pH 4.5 with a 1.8-fold increase in enzyme activity. However, due to other studies carried out in this work, it has been shown that this activation is merely transient and not cumulative regarding other methodologies, indicating that this temperature is a kind of energetic threshold, and also because FTase is a hetero-dimer, which may lead to different interactions with the niobium support. The optimization of the synthesis of FOS carried out by applying the methodology of experimental
design with the immobilized enzyme, allowing a yield increase (YFOS = 0.58) of 5%, a reduction in synthesis time (24 h) of 4 times and an increased productivity (12.05 g/L.h) of 6 times. The adsorption on niobium has shown not to involve the FTase active sites, since the addition of sucrose to the dispersion medium for adsorption did not affect the performance of the biocatalyst. On the other hand, the addition of CuSO4, which is a strong thermal stabilizing agent for this enzyme, resulted in a biocatalyst incapable of producing FOS. Considering the industrial application of FTase, it was also evaluated the effects of lyophilization over the free and immobilized enzyme. With…

▼ The purpose of this study was to produce a safer microcapsules loaded with clove and thyme oils to reduce the population of house dust mites (HDM). In the study, gelatin-based microcapsules with sizes of 4 to 85 μm were created with
agitation speed and type of oil playing critical role in governing the size of microcapsules. Microcapsules made up of single spherical units of less than 30 μm stayed individually on the fiber, whereas larger microcapsules of over 30 μm ruptured or
aggregated. Through AATCC mortality tests against Dermaphagoides farinae on the fabric, clove oil containing more phenolic monoterpenoids (eugenol) was more effective in reducing the number of live HDM (94% mortality). Clove bud oils from safe and
natural sources can be alternative materials for controlling the population of HDM.

▼ A otimizaÃÃo do processo de prÃ-tratamento (refino) do Ãleo bruto de algodÃo, para obtenÃÃo de Ãleo semi-refinado, com aplicabilidade na produÃÃo de biocombustÃveis, à o principal objetivo desse trabalho. Este por sua vez à motivado pela exploraÃÃo de matÃriasprimas menos processadas e de menor custo para produÃÃo do biodiesel. Portanto, o emprego de Ãleo semi-refinado de algodÃo pode vir a contribuir para a reduÃÃo nos custos de produÃÃo do biodiesel. As variÃveis estudadas no prÃ-tratamento do Ãleo bruto de algodÃo foram escolhidas tendo como referencial o processo de refino convencional (refino quÃmico) com soda cÃustica. Os experimentos foram realizados utilizando planejamento experimental e os resultados foram interpretados de acordo com a metodologia de superfÃcie de resposta. As variÃveis estudadas foram: concentraÃÃo e excesso de soda cÃustica (soluÃÃo de NaOH), temperatura inicial e final. As respostas foram avaliadas em funÃÃo de alguns dos mais importantes parÃmetros de qualidade do Ãleo semi-refinado obtido (cor, acidez e teor de sabÃo) e da quantidade do co-produto de refino (borra) produzido. O excesso de soda cÃustica e a temperatura inicial foram Ãs variÃveis que influenciaram de modo mais significativo as respostas analisadas, dentro do alcance experimental estudado. A eficiÃncia na conversÃo a Ãsteres metÃlicos mostrou-se dependente da qualidade (cor, acidez e sabÃo) do Ãleo semirefinado de algodÃo utilizado. A concentraÃÃo do pigmento gossipol que està diretamente relacionado à cor do Ãleo de algodÃo, sugere que o mesmo pode estar influenciando na conversÃo da reaÃÃo de transesterificaÃÃo alcalina, por estar consumindo parte do catalisador. As condiÃÃes Ãtimas determinadas experimentalmente foram: concentraÃÃo e excesso de soda cÃustica 25 % (p/p) e 100 % (p/p), temperatura inicial e final 40ÂC e 60ÂC, respectivamente. Nessas condiÃÃes otimizadas o Ãleo semi-refinado obtido alcanÃou conversÃo de 94 % (p/p) a Ãsteres metÃlicos. Entretanto, o Ãleo obtido nas condiÃÃes otimizadas, por apresentar ainda uma elevada concentraÃÃo de sabÃo, foi submetido à lavagem com Ãgua, o qual reduziu seu teor de sabÃo. Assim, com esse Ãleo lavado/seco, apÃs reaÃÃo de transesterificaÃÃo, alcanÃouse conversÃo de 96% (p/p) em metil-ester. Esse biodiesel, submetido a uma segunda reaÃÃo de transesterificaÃÃo conseguiu-se atingir uma conversÃo mÃxima de 98% (p/p), ficando dentro das especificaÃÃes estabelecidas pela ANP (AgÃncia Nacional de PetrÃleo, GÃs Natural e BiocombustÃveis)

▼ Epilepsy is a serious neurological disorder characterized by spontaneous seizures.
Despite the development of successive generations of antiepileptic drugs,
phenobarbitone has retained a unique position in the therapeutic armamentarium
and is still the most widely prescribed drug for treatment of epilepsy throughout the
world. However, the pharmaceutical industry supplies oral solid dosage forms that
are generally inadequate for pediatric, geriatrics and patients experiencing difficulty
in swallowing needs. Therefore, the present study aims at formulation and
optimization of taste-masked orally disintegrating tablets of phenobarbitone using
direct compression technique for use in specific population such as pediatrics,
geriatrics and dysphagia patients. Thus, the study begins with the determination of
the bitterness threshold of phenobarbitone in vivo. Then, taste-masked microspheres
of phenobarbitone were prepared by oil in water emulsion solvent evaporation
technique using Eudragit®E100 as a polymeric material.
The effect of formulation variable i.e., polymer: drug ratio at four different levels
(1:1, 2:1, 3:1 and 4:1) and process variable, i.e., stirring rate (500, 650 and 800 rpm)
were examined. The prepared formulations were characterized for flow properties,
particle size distribution, entrapment efficiency and percentage yield. The study
revealed that the mean particle size ranged from 386.01 ± 3.88 to 456.72 ± 3.53 μm,
the drug encapsulation efficiency varied from 88.50 ± 2.14 to 97.00 ± 1.26% of the
theoretical amount incorporated. The taste-masking efficiency was determined by
spectrophotometric analysis based on the amount of drug released from tastemasked
microspheres in pH 6.8 phosphate buffer after 5 min. Taste evaluation
studies confirmed that microspheres of phenobarbitone having a polymer: drug ratio
of 1:1 are tasteless. FT-IR spectra of phenobarbitone and the physical mixture of
drug and Eudragit®E100 1:1 suggested no interaction between the drug and
polymer.
x
The effect of various formulation and process variable on phenobarbitone orally
disintegrating tablets was investigated. The results of the experiments revealed that
the major factors that affect the tablet characteristics are compression force, level of
superdisintegrant and MCC/mannitol. Besides, since it has significant effect on
drug release, the effect of polymer to drug ratio within the microsphere on the
various tablet characteristics was also investigated. Thus, four factors, two level (2
4-1) fractional
factorial experimental
design was selected to investigate the effects of
the selected independent variables on the various responses such as disintegration
time, wetting time, hardness, drug release in 5 min and drug release in 15 min of
taste-masked orally disintegrating tablets (ODTs). Accordingly, the various models
describing the relationship of the selected variables were obtained using
Design-
Expert 8.0.7.1 software and the models were analyzed. The corresponding surface
response and…

▼ Ti-6Al-4V has a wide range of applications such as in the automotive and aerospace industries. Nevertheless, titanium alloys are very difficult to machine by conventional methods. Micro-EDM is a non-conventional machining method that uses the thermal effect of precisely controlled sparks. Manufacturers are looking for the methods and optimal settings to increase the productivity of micro-EDM in terms of lessening machining time and tool wear. Moreover, surface integrity of the machined area is crucial for some products such as biomedical implants.
The objective of this study was to investigate the effects of the micro-EDM process parameters on response variables, in order to understand the behavior of each parameter as well as to determine their optimal values. Although, there is a substantial amount of literature studying different aspects of micro-EDM, most of them were designed based on the one-factor-at-a-time experiments instead of studying all factors, simultaneously. This research was conducted through a series of experiments using a full
factorial design. An analysis of variance was employed to analyze the findings and to determine the effect and significance of each process parameters on the response variables.
The process parameters included voltage, capacitance, electrode rotational speed, and electrode coating. Voltage and capacitance were studied separately as well as in combination in terms of the discharge energy. Response variables consisted of machining time, tool wear, crater size, microhardness, and element characterization. The surface morphology and element characterization were studied through the application of SEM and EDS analysis.
The findings indicated that voltage had a decreasing effect on machining time, while it increased the crater size. Capacitance decreased machining time and tool wear. It had an increasing effect on the surface hardness. The effects of the TN-coating and electrode rotational speed were not statistically significant. Voltage and capacitance were the only parameters affecting element characterization. The affected elements included Ti, Al, C, and W. The optimal process parameters for two sets of response variables were determined using Minitab 17.

▼ The application of Ultrasound (US) irradiation to remove ammonia nitrogen from aqueous solutions, including synthetic solution and landfill leachate, at 20 kHz was investigated in this thesis. Batch experiments were carried out using two synthetic solutions with initial ammonia concentrations of 3000 and 5000 mg TAN/L in addition to two leachates from new and old landfills. The results of testing showed that US irradiation is an effective treatment technology for the removal of aqueous ammonia. More specifically, it was found that increasing sonication time and pH increased ammonia removal. The maximum observed removal of ammonia was 87.4% at a pH of 11 and sonication time of 25 minutes. Also, it was found that volatilization of ammonia to the atmosphere accounted for 0-7% of removal, the thermal effect of US accounted for 21.1-52.7%, and the non-thermal effect of US accounted for 44.5-78.8% (depending on pH and sonication time). Results of factorial design and response surface methodology showed that pH, energy output (kJ), and the interaction between the two were significant parameters. The predicted two factor interaction (2FI) model was in close agreement to the observed data (R2 = 0.94) and produced an optimum ammonia removal of 87% at a pH of 10.9 and energy output of 94.8 kJ. Analysis of variance tests showed that there were no significant differences in the percent removal of ammonia due to the non-thermal effects of US across all four solutions (synthetic and leachate) indicating that US irradiation is a non-selective treatment method for ammonia removal.

Chemistry
Analiza kvaliteta ĉvrstih materijala, u zavisnosti
od namene, obuhvata: tehniĉku analizu, elementarnu analizu, analizu
makrokomponenata i mikrokomponenata. Poseban analitiĉki zadatak
predstavlja analiza anjona u sloţenoj matrici ĉvrstog uzorka. U
literaturi i analitiĉkoj praksi postoji veliki broj metoda za
odreĊivanje halogenih elemenata, od klasiĉnih do savremenih
(instrumentalnih), koje se razlikuju kako po principima rada, tako
i po kriterijumima koji karakterišu analitiĉke tehnike, od kojih
treba izdvojiti taĉnost i reproduktivnost. Predmet rada ove
doktorske disertacije su halogeni elementi u uglju. Halogeni
elementi u uglju su prisutni u niskim koncentracijama, ali je
uticaj ovih elemenata na ţivotnu sredinu i zdravlje ljudi od
posebnog znaĉaja. Istraţivanja u okviru ove disertacije obuhvataju
analizu halogenih elemenata u uglju, rezultate istraţivanja
pirohidrolitiĉke metode za odreĊivanje halogenih elemenata, kao i
primenu eksperimentalnog dizajna za razvoj analitiĉkih
metodologija. Cilj ove doktorske disertacije bio je da se utvrdi
metodologija i odrede uslovi za istovremeno odreĊivanje fluora,
hlora i broma u uglju. U okviru ove disertacije primenjene su
statistiĉke metode za organizaciju i izvoĊenje eksperimenata, i
tehnike za obradu i analizu dobijenih rezultata. Primenom
frakcionisanog faktorijskog dizajna ispitan je uticaj šest
promenljivih na sagorevanje uglja u kiseoniĉnoj bombi i apsorpciju
gasovitih jedinjenja koja se tokom sagorevanja izdvajaju iz uglja.
Ispitan je uticaj poĉetnog pritiska kiseonika, dodatak katalizatora
i pomoćnog goriva na sagorevanje uglja, kao i tip apsorpcionog
rastvora, dodatak redukcionog agensa i vreme hlaĊenja bombe nakon
sagorevanja na apsorpciju gasovitih jedinjenja. Koncentracija jona
u apsorpcionom rastvoru merena je potenciometrijski jon-selektivnom
elektrodom (za fluorid-jon) i jonskom hromatografijom. Rezultati
frakcionisanog faktorijskog dizajna su analizirani pomoću
Pareto-grafika, grafika glavnih efekata i dijagrama interakcije
parametara. UtvrĊeno je da se dodatkom katalizatora i povećanjem pH
vrednosti apsorpcionog rastvora smanjuje koncentracija
halogenid-jona u apsorpcionom rastvoru. S druge strane, povećanjem
poĉetnog pritiska kiseonika i dodatkom pomoćnog goriva, povećava se
izdvajanje halogenih elemenata iz uglja tokom sagorevanja u
atmosferi kiseonika. Na osnovu rezultata preliminarnih
istraţivanja, pritisak kiseonika i zapremina pomoćnog goriva su
detaljnije ispitani primenom metodologije odgovora površine.
Rezultati optimizacionih eksperimenata razmatrani su analizom
grafika odgovora površine, procene regresionih koeficijenata i
analize varijansi. Pošto su se optimalni uslovi za odreĊivanje
fluora i hlora razlikovali, definisan je grupni parametar - ukupni
halogeni u uglju (engl.- total halogen in coal, TCX). Ukupni
halogeni u uglju su izraţeni preko hlora, a hlor je izabran iz
razloga što predstavlja dominantan halogeni element u uglju.…

▼ Financial elder abuse is gaining increasing attention from researchers and policy makers. Such abuse can include theft of money as well as misuse of assets such as property. This research applied judgement analysis methodology to explore professional decision making in the context of such abuse and to identify the nature of the cues used to detect and prevent abuse. Participants included social care, health and banking professionals, who were established as key decision makers. In Phase I, semi-structured interviews (n = 63) were conducted. The critical incident technique was used to identify cue use and decisions taken in the most recent case experienced. Key cues for both social care and health professionals included the nature of the 'financial problem suspected', the older persons 'mental capacity' and the 'identifier of the abuse', this being whether the abuse was directly observed or instead reported by a third party. A separate cue used by health professionals was the individual's 'physical capacity'. Banking professionals did not use physical or mental capacity as cues, but independently considered 'who was in charge of the money'. Decisions made by social care professionals included determining whether safeguarding procedures should be implemented. In Phase II, a factorial survey approach was applied whereby social care, health and banking professionals (n=223) were presented with case scenarios incorporating the cues from Phase I in addition to cues from literature review. Multiple regression analysis and incremental F-tests identified the cues that explained a significant amount of the variance in judgements of certainty of abuse and likelihood of taking action. For example, for social care and health professionals this included the older person's mental capacity, and the nature of the financial problem suspected. The findings could be used to develop a training tool to enable other professionals to improve their strategies for detection and prevention of financial elder abuse.

▼ During compression moulding of sheet moulding compounds, voids are formed that can deteriorate the surface finish of the final product as well as its properties such as the electrical insulation. A large number of processing and material parameters can however be tuned in order to reduce the amount of voids in the final product. There is no profound investigation coupling such parameters to the void content. Hence, factorial design is here used to plan an experimental series where material as well as processing conditions are varied. In particular vacuum assisted compression moulding is used in a circular shaped mould. The experimental series is evaluated by counting the number of surface voids on the plates and by measurement of their electrical insulation. One result is that the latter can be considerably improved by choosing optimal processing conditions.

▼ Recent studies on Typha spp. commonly-known as cattail has revealed its prospect of being used as a new source of natural fiber. An investigation was carried out to examine the influence of extraction time, temperature, and concentration of alkali on the physical and mechanical properties of cattail fibers for bio-composite applications. The fibres were obtained from the leaves of Typha latifolia L. using 3 levels of concentration (4, 7, 10%, w/v) of NaOH with 4 levels of temperature (70, 80, 90, and 95° C), and 5 levels of time (4, 6, 8, 10, and 12 h.) in a 3*4*5
factorial experimental
design. The three-way
factorial ANOVA revealed that yield (%), diameter, tensile strength, elongation at break (%), and moisture regain (%) of fibres were influenced significantly (P < 0.05) by time, temperature, concentration and the interaction between temperature and concentration. For modulus of elasticity of fibres, the effects of time, temperature, the interaction between time and concentration, and the interaction between temperature and concentration were found significant (P < 0.05).
After analyzing the estimated treatment means of response variables, it was determined that the mechanical properties of cattail fibres have similarities with sisal, and coir fibres and can be used in automobile and packaging applications. The extraction parameters were optimized using desirability function analysis (DFA) which determined the optimum extraction time, temperature and concentration of NaOH as 10 h., 90º C, and 7% for automobile applications and 6 h., 90º C, and 7% for packaging applications.

▼ Companies increasingly believe that sponsorship, and in particular sport sponsorship, can help them achieve their respective strategic objectives. Achieving sales objectives are especially important in the context of sport sponsorship, given that managers are under increasing pressure to justify their sponsorship expenditure, and that over two-thirds of all sponsorships are directed towards sports properties. However, isolating a sponsorship s contribution to a company s sales figures is difficult to accomplish, and even if this were possible, understanding the mechanisms behind consumers behavioural responses to that respective sponsorship would still constitute a challenge. Hence, understanding consumers behavioural purchase intentions, and what drives these intentions within sponsorship contexts, is of paramount importance. That said, little is known about what drives consumers purchase intentions in sponsorship settings. A greater understanding of consumers behavioural intentions within concurrent sponsorship settings is necessary. Concurrent sponsorships involve multiple brands sponsoring a property at the same time. As such, they are a more realistic and common sponsorship context than simple sponsor-sponsee dyads are. It is important to examine concurrent sponsorships because a collective is formed when multiple sponsors are involved. In turn, social psychology highlights that a collective is characterised by the degree to which its a priori members are perceived as a group. Groups are perceived qualitatively differently to dyads, and can also be perceived differently to the sum of their respective constituent parts. Moreover, the extent to which people perceive a collective as a group can impact upon their subsequent evaluations of that group and that group s actions. Consequently, consumers evaluations of a sponsee s concurrent sponsors and the sponsee itself may be affected by how concurrent sponsorships are perceived, which in turn may affect consumers behavioural intentions. Hence, it is imperative that concurrent sponsorship contexts are investigated. That said, there is scant literature investigating concurrent sponsorships, with sponsorship research historically focussing on sponsor-sponsee dyadic settings. This thesis contributes to our understanding of concurrent sponsorship settings of major sporting events by examining how people s perceptions of concurrent sponsors entitativity influence both their purchase intentions towards a focal concurrent sponsor and their sponsee equity evaluations. An online questionnaire, utilising sponsorship vignettes (scenarios) as part of a factorial survey design, was sent to respondents of a mid-sized UK-based university. Scenarios were used to manipulate respondents into perceiving two concurrent sponsorship settings: a concurrent official providers sponsorship setting and a concurrent official financers sponsorship setting. Hypotheses were tested through Lisrel 8.71 where confirmatory factor analysis (CFA) and structural equation modelling (SEM) were performed.…

▼ The concept of corporate social responsibility (CSR) has received pronounced interest at both the academic and industry levels, associated with the recognition that businesses have responsibilities towards society beyond profit making (Othman & Othman, 2014). The tourism industry relies heavily on environmental and cultural resources within tourist destinations (Sheldon & Park, 2011), requiring businesses to actively engage with social and environmental issues (Henderson, 2007). While there is an increased interest in CSR in the tourism sector at both the academia and business levels, CSR tourism research is underdeveloped (Coles, Fenclova, & Dinan, 2013; Sheldon & Park, 2011; Wells, Smith, Taheri, Manika, & McCowlen, 2016). Moreover, little academic attention has been paid to CSR among major tourism attractions, with the exception of casinos (Coles et al., 2013). Consumers generally act as drivers for CSR activities (Kotler, 2011), making it important for businesses to understand how tourists respond to different types of CSR. However, assessing consumer responses to CSR is still in its infancy as a research area (Marchoo, Butcher, & Watkins, 2014). To address the gaps found in the literature, this study focused on examining festival-goers' behavioral intentions and desires related to different CSR initiatives (environmental, social, and economic) at music festivals. This study employed experimental
design to investigate festival-goers' behavioral intentions and desires towards CSR activities undertaken by music festivals. Specifically, this study placed three CSR initiatives (environmental, social, and economic) within the Model of Goal-Directed Behavior (MGB), thereby forming an Extended Model of Goal-Directed Behavior (EMBG). The data was collected via an online survey-embedded experiment through Amazon Mechanical Turk (Mturk). The results revealed that environmental CSR initiative was effective in predicting behavioral intention and desire; however, when environmental CSR initiative variable was combined with the MGB, the effect of environmental CSR on desire lost its significance. The results indicated that both the MGB and the EMGB were effective in explaining festival-goers' behavioral intentions and desires for the EMGB. Accordingly, the process of extending the MGB was successful and environmental CSR initiative was the only significant predictor of desire and behavioral intention among the three CSR initiatives.

▼ Hydrogen has been emerging as a suitable energy carrier in recent years. As political policies challenge the emission of greenhouse gases, the need to research sustainable energy technologies has increased. This research investigated the processes of steam methane reform (SMR), solar steam methane reform, and solar methane cracking (SMC). The three processes were modeled in Aspen Plus and the system parameters of temperature and steam-to-carbon ratio were varied. Objective functions were derived and optimized using the particle swarm optimization technique to maximize hydrogen production with minimized cost. The three processes were finally compared economically to determine if new methods of hydrogen production are fiscally capable.
Subjects/Keywords: Aspen Plus; factorial design; hydrogen production; particle swarm optimization; solar methane cracking; steam methane reforming
