▼ Vegetation water content (VWC) is an important parameter for sustainable land and water management. In agriculture, VWC can be used to monitor drought and assess crop productivity. Being able to monitor VWC is important to reduce agricultural vulnerability and scientifically manage agricultural water use. Due to the dense in-situ networks are expensive and have difficulties in capturing the large spatial variability of VWC. Therefore, remote sensing has great potential in VWC monitoring. With the application of remote sensing, worldwide data with coarse or fine spatial and temporal resolution can be extracted with relatively low cost. Vegetation Optical Depth (VOD), extracted from the radar remote sensing observations, is a dimensionless parameter that highly related to VWC. Thus, VOD can be used as an indicator for VWC. The present research aims to thoroughly analyze the relation between VOD and VWC. High temporal backscatter data and detailed field experiment data of soil moisture and vegetation water content during a full growing season of corn (between 18 April 2018 to 13 June 2018) were used. Correlations between VOD and VWC were analyzed. The result shows that VOD is highly related to VWC_bulk. However, the linear relation between VWC_bulk and VOD is only valid before the heading stage at both co- and cross-polarization. Then, random forest machine learning was conducted to determine the sensitivity of VOD to the water content of different parts of the plant. This sensitivity analysis contains two parts: a) the sensitivity of VOD to the water content of different vegetation components and b) The sensitivity of VOD to stem and leaf water content at different heights. The results of a) show that VOD is more sensitive to stem and leaf water content in the vegetative stage whereas more sensitive to ear water content during the reproductive stage. Besides, stem, leaf and ear water content can better capture the VOD variation during the vegetative stage. The result from b) suggests that VOD can provide information about the vertical distribution of moisture inside the canopy. Finally, a cross-comparison was conducted between VOD and other commonly used vegetation indicators, which includes NDVI and Cross-Ratio. VOD is available regardless of cloud conditions and is, therefore, more reliable than NDVI. Compared with cross-ratio, VOD is better related to vegetation moisture dynamics.

▼ A large-scale nourishment known as the Sand Motor has been implemented along the Dutch coast as a Building with Nature solution designed for the upcoming 20 years. Given the long-term period of the project, a combination of in situ measurements and remote sensing techniques are currently in use. An X-band radar system is deployed at the Sand Motor, but requires further research into its applicability in such a dynamic coastal climate. Radar data can be processed into hydrodynamic parameters such as waves, currents and bathymetry information through use of a 3D Fast Fourier Transform (FFT). This technology is highly desirable for coastal engineering applications since it presents a relatively effortless method to capture high resolution spatial and temporal hydrodynamic parameters. The objective of this research is to develop an X-band radar depth inversion model at the Sand Motor for further investigation into remote sensing as an accurate tool for estimating nearshore hydrodynamics. The developed model should be able to accurately estimate hydrodynamic parameters from raw X-band radar images with high temporal and spatial resolution. This thesis explains the development, calibration and validation of the X-band MATLAB Fitting (XMFit) model at the Sand Motor for a single storm in October 2013. XMFit proved to be a valuable remote sensing tool for extracting nearshore hydrodynamics based on in situ comparisons. The SeaDarQ software developed by Nortek B.V. is also used as a quality benchmark. The storm results showed that the XMFit is more robust and accurate relative to the currently available SeaDarQ software. A sensitivity analysis was completed to further analyze the spatial and temporal patterns associated with XMFit accuracy. Spatial statistics indicated high error around the edges of the radar domain, which led to a reduced radar footprint by implementing a spatial cutoff of 2.5 km. The smaller domain results in much less scatter with a near-constant linear bias of 2 m. High accuracy in XMFit is directly linked with waves exceeding 1 m, wind speeds exceeding 12 m/s and the alignment of wind and waves. The metocean limits help conclude that XMFit requires spectra spreading in wavelength-frequency space to help constrain the dispersion shell. This finding directly links with locally generated wind waves, more commonly referred to as wind sea. Ideal results based on the spatial and temporal limits further reduced the linear bias to approximately 1.6 m. The ideal conditions show a much better agreement between radar-derived and in situ bathymetry and hydrodynamics. A relationship between the inaccuracy of XMFit during flood tide was linked to complex nearshore hydrodynamics around the Sand Motor. Note that the flood tide at the Sand Motor exhibits complex flow structures (i.e. stratification and large scale eddy formation on the lee side). XMFit averages these complex 3D flow structures evident during flood tide into a single large computational cube, which drastically simplifies the hydrodynamics.

▼ Monitoring of coastal hydrodynamics over a relatively large spatial extent and a long temporal period is essential to assess the impact of coastline interventions on several functions. An example of a recent coastline intervention is the Sand Engine, a pilot project for optimization of (future) coastline maintenance. This innovative pilot project is therefore subject to an intensive research and monitoring program that allows for development and validation of new measurement techniques. Continuous series of spatial hydrodynamics measured by remote sensing instruments have the potential to complement the temporally and spatially limited measurements of in-situ instruments. In this thesis, the accuracy of hydrodynamics measured with a land-based X-band radar at the Sand Engine is examined. The mapping of the sea surface by an X-band radar results in wave dispersion patterns in the radar domain over time. This allows for the extraction of spatial maps of the hydrodynamic parameters d and U by spectral (Fourier) analysis of wave dispersion patterns on a limited spatial scale (computational cube size). Previous research has shown that the spatial and temporal scale of wave dispersion analysis are critical factors for the accuracy of remotely-sensed currents. The recently developed open-source XMFit algorithm (Friedman(2014)) is used to extract X-band radar currents. It is not exactly known what X-band radar derived currents exactly represent. In addition, there is no agreement whether a radar measures Eulerian or Lagrangian currents. Therefore, the objective is to find the relation between spatial scale of wave dispersion analysis and X-band radar current measurement accuracy at the Sand Engine by performing point and spatial validation of currents obtained by analysis of wave dispersion on different spatial scales. The Sand Engine study site was selected due to availability of both Eulerian ADCP and Lagrangian drifter measurements. The relation between measurement accuracy and computational cube size was found to be hyperbolic for both the point and spatial validation, which is connected to the hyperbolic relation between cube size and spectral resolution dk. In-situ current estimates are consistently overestimated by XMFit for grid points within the first 500 m from the coastline. Non-linear wave effects cause anomalies in the image spectrum compared to the definition of a useful spectrum. These anomalies do not follow linear theory on which the method is based and therefore have a negative effect on the current estimate of XMFit. In the point validation at two ADCP locations, XMFit current estimates were compared to pseudo-Lagrangian ADCP currents. The pseudo-Lagrangian ADCP currents are obtained by correcting Eulerian ADCP measurements for the surface Stokes drift. A direct comparison of XMFit to the Stokes-drift corrected ADCP measurements proves that the correlation in cross-shore direction is high. This supports that X-band radar currents are Lagrangian. The spatial validation by drifter measurements is performed… Advisors/Committee Members: Reniers, A.H.J.M. (mentor), Tissier, M. (mentor), Hoekstra, R. (mentor), Friedman, J. (mentor), Swinkels, C.

▼ An experimental and numerical study of absorption of ammonia vapor bubbles into a constrained thin film of ammonia-water solution is presented in the context of a potential reduction in size of a heat-actuated heat pump component. A large-aspect-ratio channel with a depth of 600 µm restricts the thickness of the weak solution film, while ammonia vapor bubbles are injected from a porous wall. Experiments are performed at a nominal system pressure of 6.2 bar absolute and at an inlet weak solution temperature of 75ºC. A counter-flowing coolant in a minichannel removes the generated heat of absorption. The mass flow rate of the weak solution, vapor flow rate, coolant inlet temperature, and mass flow rate of the coolant solution are varied. Two absorber channel geometries are considered: 1) a smooth 600 µm channel, and 2) a stepped geometry that has 2-mm deep trenches across the width of one of the channel walls. The 1-D, steady state species and energy transport equations, are solved for the smooth-channel absorber to yield, along the length of the channel, concentration and temperature profiles of the solution stream and the temperature profile of the coolant fluid stream. Experimental results indicate that overall heat transfer coefficients vary from 700 W/m²-K to 2,300 W/m²-K, while the mass transfer conductances range from 0.024 kg/s-m² to 0.24 kg/s-m². The coolant inlet temperature has a significant effect on the mass transfer rates. At the highest inlet coolant temperature of 58ºC, up to 1.5 g/min of vapor is at best absorbed into 35 g/min of weak solution for the smooth absorber plate, while at the lowest coolant temperature of 30ºC, up tp 3 g/min of vapor is absorbed in 35 g/min of weak solution with the same absorber plate. For the stepped absorber geometry, only 1 g/min of vapor is absorbed into 35 g/min of weak solution for the highest coolant temperature of 58ºC, while for the lowest coolant temperature of 30ºC, 5 g/min of vapor is absorbed in 40 g/min of weak solution. Trends of local variation of temperature and convected vapor from the numerical parametric study complement experimental results and provide further insight into the performance of the absorber. Based on the experimental results, a preliminary size estimate for the absorber to operate in a cooling cycle with a 6 kW evaporator load is provided. Other considerations such as strong solution exit subcooling and porous plate pressure drop are also addressed. Advisors/Committee Members: Narayanan, Vinod (advisor), Apte, Sourabh V.

Abstract - When surgically drilling blind holes in bone using a Water Jet (WJ), control over the resulting depth is a challenging issue of paramount concern. This thesis was part of a project aimed at replacing the awl and mallet technique used in traditional microfracture procedures with an arthroscopic high-pressure WJ instrument is capable of accurately drilling 2–4 mm deep holes in subchondral bone. The focus of this paper was to develop, analyze and evaluate concepts for ensuring the depthwise accuracy of a microfracturing WJ. Research was performed on both WJ systems and the microfracture procedure, and a thorough problem analysis detailing all concerning requirements and parameters was set up. It was determined that due to the strong non-uniformity of human bone, both spatially and between subjects, a WJ capable of monitoring the depth and implementing a closed-loop control system was needed to ensure safe and accurate drilling. To measure the depth of the hole and allow for feedback control, a flexible Nickel Titanium probe concept was devised and tested. The concept featured a 3D printed nozzle with built-in WJ orifice and depth probe, which could be extended down the hole made by the WJ by an ex-vivo actuator featurimg load and displacement sensors. When the load sensor detected a sudden rise in extension resistance, bottom contact was assumed and the hole depth was calculated based on the displacement of the probe. A proof-of-concept experiment showed the viability of using a flexible probe to measure the depth. Additionally, the algorithm produced for calculating the depth was shown to be robust against the hysteresis and backlash exhibited by the setup. When probing holes with depths of 0, 1, 2, 3, 4 and 5 mm and bore diameters of 1, 1.5, and 2 mm drilled in solid PMMA, the prototype managed an error mean of 0.00 mm with a SD of 0.19 mm. To test the probe in holes shaped as expected during microfracture surgery, a virtual interference experiment was carried out using mCT scans of WJ-drilled bones and simulated probes of varying diameters. Seven scans were probed from 4 different angles each; the results suggested that a probe with a 0.2–0.3 mm diameter was optimal in terms of traversing the hole without blockages and without risking over-penetration. Moreover, this thesis produced recommendations on carrying the project further, towards a fully integrated system capable of drilling accurate blind holes in human bone, in a closed-loop depth-controlled manner.

▼ Recently, motivated by the discovery of graphene, two-dimensional materials have attracted more attention. MoS2 is one of focused two-dimensional material [1,2], owning two its gapped energy structure and the similar crystal structure with graphene. The energy structure of MoS2 changes from the indirect band gap of 1.29 eV to the direct band gap of 1.9 eV when it is thinned from bulk to monolayer [3-7]. Recently, Yen-Hung Ho et al. have studied the Landau levels split on monolayer MoS2 in high magnetic fields, which suggests the energy gap will show linear dependent with increase of magnetic field [8]. However, the high-field experimental evidence still lack. To study the magnetic-field dependent of energy structure, we have constructed an optical spectrum system. Similar experiments were performed in a middle-pulsed-high-magnetic-field system that is located in the International MegaGauss Science Laboratory, The Institute for Solid State Physics, University of Tokyo, Japan. In Taiwan, we can measure the spectrum from 90 K to 300 K. In Japan, we measured only in 4 K, 77 K and room temperature. In the literature, the monolayer MoS2 film have two absorption peaks, 1.95 and 2.08 eV, in the visible region [9]. The absorption peaks show blue shift when temperature decreases. This result is same as other one, the reason just caused by thermal expansion [10]. We observed that the temperature dependence of absorption peak showed dramatic change at T ~ 200 K, which cannot be explained by thermal expansion effect. The thermal-induced lattice anomaly could cause it. To know the origin of this behavior, more detailed experiments are needed. We performed the magnetic-field-dependent optical measurements by using the pulse magnetic fields. With our home made coil design we acheieved peak field value of 8 T, 29 T and 52 T. When T = 77 K, the peaks behave red shift with increase of magnetic fields. In case of 4 K, the peaks show no tendency with magnetic field. Due to limited magnetic fields for the measured optical spectrum, it is hard to give a convincible conclusion on magnetic field effect of MoS2. After we synthesize new samples, we will perform further experiments in more different magnetic fields with the pulsed-magnetic-field system in Taiwan.

L’amélioration des performances des dispositifs pyrotechniques requiert une description fine de la transition choc/détonation (TCD) dans les explosifs. Les modèles de TCD existant comportent une part d’empirisme qu’il est souhaitable de réduire à l’aide de données expérimentales à l’échelle microscopique. Pour cela, nous avons mis au point un dispositif permettant de générer des chocs de 2 à 30 GPa et d’analyser en temps réel l’évolution du matériau par spectroscopie. Le système de mesure comporte un laser sonde et un ensemble de spectroscopie Raman rapide. Ce dispositif a été utilisé pour l’étude des mécanismes d’initiation d’un explosif appelé TATB. L’évolution des spectres Raman en fonction de la pression révèle un couplage entre les modes de vibration des groupements NO2 et NH2 provenant de la présence d’un réseau de liaisons hydrogène au sein du TATB. Ce réseau est responsable de la grande stabilité de la molécule. Quelques différences entre les régimes statique et dynamique, imputables à l’effet du chauffage par le choc, sont mises en évidence ; elles semblent indiquer un affaiblissement du réseau de liaisons hydrogène. Les résultats font également apparaître une atténuation progressive du signal Raman sous choc avec la pression. A partir de 9 GPa, le signal n’est plus détectable. Des visualisations par caméras rapides montrent que cette atténuation du signal Raman est accompagnée d’un assombrissement progressif du TATB qui devient totalement opaque à 9 GPa. Des expériences de réflectivité sous choc ont montré que ces deux phénomènes sont dus à un élargissement de la bande d’absorption du TATB.

Improving performances and safety of pyrotechnic devices requires a sharp knowledge of the shock to detonation transition phenomenon in high explosives. Current models to describe this phenomenon largely involve empiric parameters based on macro scale experiments. To improve predictive capability of these models, it is necessary to get experimental data at a microscopic scale. To provide such data, we developed an experimental setup to shock a high explosive up to 30 GPa and perform in-situ measurement of its Raman spectra under this loading. The device includes a shock generator based on explosive driven plate impact triggered by a laser pulse and a diagnostic involving an excitation laser and a spectrometer coupled with an intensified CCD. This experiment has been applied to an insensitive high explosive named TATB. Pressure driven evolution of the Raman spectra reveals an important coupling between NO2 and NH2 vibration modes that is due to a strong H bonding within TATB crystal. This bonding is clearly linked to TATB high stability. Differences observed between dynamic and static loading are attributed to shock heating resulting in H bonding weakening. Moreover, results show a progressive decrease in Raman spectra intensity with increasing shock pressure down to a complete signal loss at about 9 GPa. High speed visualisations reveal a progressive darkening of the sample leading to complete opacity at 9 GPa.…

▼ Tellurium is a member of the chalcogen group in the periodic table and is known to be a better semiconductor material when compared to sulfur and selenium. By introducing tellurium into the kesterite structure there would be an improvement in the semiconducting property of the kesterite material. This research focused on incorporating tellurium into kesterite structure in order to reduce its band-gap thereby improving its light absorption and ultimately lead to a more efficient photovoltaic effect. For a typical synthesis, kesterite nanoparticles were synthesized by anion hot injection process which involved the injection of the anion precursor comprising of sulfur, selenium and tellurium in diethylene glycol into a solution containing the cation precursor which are copper (II) chloride, Zinc chloride and tin (II) chloride which are dissolved in diethylene glycol. The synthesized nanoparticles were copper zinc tin sulfide (CZTS), copper zinc tin sulfide selenide telluride (CZTSSeTe) and copper zinc tin sulfide telluride (CZTSTe). Morphological characterization of the synthesized nanoparticles was carried out by high-resolution scanning electron microscopy (HRSEM) and high-resolution transmission electron microscopy (HRTEM) to obtain the shape of the surface and internal structure of the nanoparticles respectively. The micrograph obtained from HRSEM shows that all synthesized nanoparticles had a flower-like surface appearance which is a common morphology obtained for non-vacuum synthesized kesterite nanoparticles. The micrograph obtained from TEM showed that all nanoparticles were agglomerated and had a black surface covering which attributable to the solvent used during synthesis, washing and centrifugation. The internal structure of the synthesized nanoparticles was obtained through small angle x-ray scattering (SAXS) plot of the shapes. The shape obtained for the nanoparticles were core shell hollow sphere for CZTS, core shell dumb-bell for CZTSSeTe and solid sphere for CZTSTe.

Silicon dioxide is a material of particular technological interest for its exceptional combination of properties. Indeed, both its crystalline forms and amorphous phase are widely used in many electronic and optoelectronic technologies. The amorphous form (a-SiO2) is present in many electronic devices as a gate dielectric in MOS transistors. Optical fibers are mostly made of a-SiO2 as it shows a very good optical transmission over a large range of frequencies. In all these applications, defects and impurities play an important role in the actual properties of the devices. In particular, they can cause an attenuation of the optical signal and a decrease of the bandwidth in optical fibers. An accurate understanding of these degradation processes is thus essential for the development of quality glasses as well as for improving their properties. In this work, the electronic and optical properties of pure and defect-containing silica are investigated by means of first-principles approaches. Optical spectra for the pure bulk systems are obtained with good agreement with experiment. A reverse engineering procedure is suggested to accurately determine the band gap of both the crystalline and amorphous phases, thus solving this long-standing problem. The electronic properties of hydrogen states in silica are then investigated. Their configurational, electronic and stability properties are obtained for a large statistical ensemble. Other, more technical topics are also covered in this work. The supercell and plasmon-pole approximations in GW electronic structure calculations are studied in detail in order to assess their reliability. Finally, a recently proposed exchange-correlation functional is carefully analyzed. It is shown to yield much better band gaps within density functional theory but at the expense of a less reliable valence electronic structure.

▼ Intravascular volume is maintained by complex interplay between organ systems with a main role for renal sodium, and water handling. The glomerulus filters a large quantity of water and salt daily with the majority of sodium, water and calcium being reabsorbed from the proximal tubule (PT). The renal reabsorption of sodium, water and calcium are interconnected. Apical influx of sodium from the PT occurs via NHE3 in exchange for a cytosolic proton. Cytosolic sodium is excreted back into the blood via either sodium potassium ATPase or a sodium dependent bicarbonate transporter. The rate-limiting step for NHE3 activity is the presence of a cytosolic proton. This is generated by cytosolic carbonic anhydrase II (CAII), an enzyme mediating the catalysis of CO2 and H2O to form HCO3- and H+. CO2 and H2O enter the PT epithelial cell through the water channel aquaporin-1 (AQP1). Osmotically driven water flux across the PT also drives calcium reabsorption from this segment, a process linked by NHE3. CAII interacts with many membrane transporters including NHE1, AE1, MCT1 and NBCe1. We identified potential CAII binding sites in both NHE3 and AQP1. A primary hypothesis of this thesis is that CAII physically and functionally interacts with both NHE3 and AQP1. CAII and NHE3 were closely associated in a renal proximal tubular cell culture model as revealed by a proximity ligation assay. Direct physical interaction was confirmed in solid-phase binding assays with immobilized CAII and C-terminal NHE3 glutathione-S-transferase fusion constructs. To assess the effect of CAII on NHE3 function, we expressed NHE3 in a proximal tubule cell line and measured NHE3 activity. NHE3-expressing cells had a significantly greater rate of intracellular pH recovery than controls. Inhibition of endogenous CAII activity with acetazolamide significantly decreased NHE3 activity, indicating that CAII activates NHE3. To ascertain whether CAII binding per se activates NHE3, we expressed NHE3 with wild-type CAII, a catalytically inactive CAII mutant (CAII-V143Y), or a mutant unable to bind other transporters (CAII-HEX). NHE3 activity increased upon wild-type CAII coexpression, but not in the presence of the CAII-V143Y or HEX mutant. These studies support an association between CAII and NHE3 that increases the transporter's activity. CAII colocalizes with AQP1 in the renal proximal tubule. Expression of AQP1 with CAII increased water flux relative to AQP1 expression alone. Expression of catalytically inactive CAII failed to increase water flux through AQP1. Proximity ligation assays revealed close association of CAII and AQP1, an effect requiring an acidic cluster of amino acids in the cytosolic tail of AQP1. This motif was also necessary for CAII to increase AQP1-mediated water flux. Red blood cell ghosts resealed with CAII demonstrated increased osmotic water permeability compared with ghosts resealed with albumin. Renal cortical membrane vesicles isolated from CAII-deficient mice has reduced water flux, which is measured by stopped-flow light scattering.…

Their removal from industrial aqueous solutions, wastewater and hydrometallurgical process solutions prior to their release to the environment is necessary for a healthy biosphere which includes human beings, aquatic life and plants. There are several technologies used to remove metals such as Cu, Co, Zn, Hg from water. These include among others, ion exchange, membrane filtration, activated carbon, electrochemical treatment, chemical precipitation, reverse osmosis, coagulation and flocculation. Although they have been used in the removal of metal pollutants from water, these technologies produce high quantities of sludge. They are also expensive to operate and need well trained personnel to operate large chemical plants. Since current metal removal techniques have limitations, a need exists for the development of environmentally friendly and cost effective techniques for the removal of metal ions from aqueous media. The focus of this research project is on the use of micro-organisms as biosorbents for copper and cobalt pollutants in aqueous solutions. The experimental work was carried out on a laboratory scale and a summary of our findings is presented as follows: Synthetic sulphate solutions of copper and cobalt were prepared using CuSO4. 7H2O and CoSO4. 5H2O powders. Concentrations of 0.002 M, 0.07 M and 0.2 M copper and cobalt ions in solution were used as test synthetic solutions for our experiments. Mixed strains of bioleaching bacteria were sourced from Mintek (Randburg, South Africa) to test the viability of this research project. This consortium contained Acidithiobacillus caldus, Leptospirillum spp, Ferroplasma spp and Sulphobacillus spp. These bacteria were able to remove up to 55% copper and 25% cobalt from low concentrated copper and cobalt sulphate solutions with 69% and 58% removal demonstrated in the case of mine effluents emanating from metallurgical operations. Different strains of micro-organisms (bacteria) were isolated from mine dumps and mine operation effluents and soil from the Palabora Mining Company in Limpopo, a northern province in South Africa and Nigel Town in the Gauteng Province. The isolated bacterial strains were then identified using PCR analysis and strains from the Bacillus genre were found to be predominant. Shewanella spp was also present. Pseudomonas spp was isolated using Pseudomonas agar base. These bacteria were then cultured at different species-specific culture conditions and their capabilities to remove copper and cobalt ions first from synthetic solutions and subsequently from mine effluents emanating from metallurgical operations were tested. In the first stage of biosorption experiments, factors that affect biosorption mechanisms which include, solution concentration, biomass concentration, pH, contact time and the presence of other metal co-ions were investigated. A decrease in the amount of metal…

Техничко-технолошке науке - Инжењерство заштите животне средине / Applied sciences - Environmental Engineering

Предмет истраживања у оквиру израде ове докторске дисертације је проналажење и развој нових материјала који имају добра адсорпциона и техно-економска својства применљива у реалним системима за уклањање јона тешких метала и арсена. Испитивања су укључивала:  унапређење адсорпционих својстава бигра импрегнацијом наночестицама бакра и испитивање добијеног адсорбента у реалним системима;  различите модификације отпадних полиакрилнитрилних влакана у циљу побољшања њихових адсорпционих особина према јонима тешких метала и арсену;  оптимизовање синтезе и процеса адсорпције јона тешких метала и арсена на синтетисане адсорбенте. У експериментима адсорпције коришћен је природни материјал бигар (природни калцит) и отпадна влакна полиакрилнитрила. Бигар је погодним физичким и механичким методама припремљен за даљу модификацију преципитацијом наночестица бакра. Преципитација наночестица бакра на бигар вршенa је комбинацијом различитих метода и количина наночестица у циљу добијања адсорбента са најбољим адсорпционим карактеристикама. Отпадна влакна полиакрилнитрила модификована су површинском модификацијом амино групама комбинујући услове модификације (температуру, концентрацију реактаната и pH вредност) у циљу добијања адсорбента са великим бројем активних амино група и најбољим адсорпционим карактеристикама за катјоне. У циљу постизања добрих адсорпционих карактеристика за анјоне површински модификована влакна су накнадно импрегнирана наночестицама гетита. Резултати истраживања у оквиру ове докторске дисертације дају нам: нове јефтине и ефикасне материјале различитих текстуралних својстава; оптималне поступке синтезе, површинске модификације, таложења и пост-процесирања добијених адсорбената како бисе добили материјали са побољшаним адсорпционим својствима у процесима уклањања никла, олова, кадмијума и арсена из воде; потпуну карактеризацију синтетисаних адсорбената применом различитих инструменталних техника: SEM, ТЕМ, HRD, FTIR, RAMAN, pHPZC, BET итд. допринос сазнањима о међусобном утицају својстава материјала и параметара процеса на ефикасност уклањања тешких метала; бољи приступ у потпуном сагледавању процеса и синтезе нових материјала на основу експерименталних и резултата моделовања; Такође се очекује да ће развијена методологија омогућити проактивно и ефикасно вођење политике заштите животне средине и одрживог развоја у циљу побољшања квалитета животне средине.

▼ The Kgwakgwe manganese deposit is 4 km southwest of Kanye village (70 km west of Gaborone, Capital City) in Botswana. The manganese deposit is surrounded by about 30 boreholes which supply the entire Kanye population with water, through pipes into each home. Weathering of manganese and other elements from rocks (due to the geology of the area) leach into underground water within the catchment. The study assessed the quality of drinking water from the boreholes and estimated their compliance with World Health Organization Recommended Guidelines. Determined physico-chemical parameters were: conductivity, alkalinity, total dissolved solids, turbidity, pH, temperature, total hardness, chloride, colour, nitrate, sulphate, sodium and potassium). Heavy (arsenic, lead, cadmium, chromium, nickel, zinc and copper) and trace (manganese, iron and magnesium) elements are determined by atomic absorption spectrophotometry; while soil and vegetation samples were analyzed using Energy Dispersive X-Ray Fluorescence (EDXRF). Multivariate Analysis was used to differentiate boreholes based on the physico-chemical parameters. Principal Component Analysis (PCA) was used to evaluate the influence of the parameters on the borehole. The study revealed that Manganese (0.038 mg/L-0.1295 mg/L) was the only element that was found to be above the recommended WHO limit for Mn in water (0.05 mg/L). Iron was below the instrumental detection limit of 0.001 mg/L. Levels of Chromium ranges from 0.02 mg/L to 0.0355 mg/L which is below the WHO limit of 0.1 mg/L, as well as for magnesium (0.097 mg/L to 1.2277 mg/L) which was below the WHO limit of 100 mg/L. The levels of Mn in two soil samples (Sample 01 and Sample 03) analyzed, which were around the manganese deposit were 9747 mg/kg and 408.7 mg/kg respectively. Although these values were above the WHO acceptable limit of 12 mg/kg, when they were comparable to values (35 mg/kg to 24907 mg/kg) obtained in a similar study conducted in the study area. Fe in the soil samples were 27524.51 mg/kg for sample 01 (about 2 km from the Kgwakgwe Mine) and 22133.65 mg/kg for sample 03 (about 500 m from the Kgwakgwe Mine); comparable to1116 mg/kg-870 766 mg/kg obtained in 2004 by Ekosse. For vegetation, Mn in spinach leaves was 69.7 mg/kg; and Hay was below detection limit. Mn in spinach was below the WHO limit of 200 mg/kg, but comparable with 26.2 mg/kg to 3611 mg/kg obtained in 2004 by Ekosse in a similar study. Fe in spinach leaves were below detection limit while Hay leaves had 122.69 mg/kg. The level obtained was within the 101.2-3758 mg/kg by Ekosse in 2004. The levels of As, Ni, Pb, Cu, Cd, Zn in water samples were all below the instrument detection limit of 0.001 mg/L. pH ranged from 7.12 to 9.47; conductivity (493 to 1129 μs/cm); Total Hardness (88-696 mg/L). TDS (28 to 552 mg/L); Chloride (9.99-99.97 mg/L); Alkalinity (10-296 mg/L). Sodium levels ranges from 17.5 to 49.3 mg/L; Potassium levels (3.9 to 45.3 mg/L). The nutrient load, sulphate (below detection limit to 9.09 mg/L); nitrates (0.171-2.527 mg/L).…

The influence of voids on the moisture uptake of epoxy has been studied. Specimens with void contents from 0 to about 50% were prepared. Void geometry and content were analyzed using microscopy and density methods. Void containing dry samples were characterized by Differential Scanning Calorimetry and Dynamic-Mechanical Analysis which verified consistency of chemistry of the epoxy network. The moisture uptake of specimens immersed in distilled water at 40 °C was monitored. The rate of absorption and saturation moisture content increased with increasing void content. The moisture uptake of void-free and void containing specimens was non-Fickian. The Langmuir model provided good fits to the experimental results for specimens with low to medium void content, although the moisture uptake of the high void content specimens showed substantial deviations from the Langmuir diffusion model. The moisture diffusivity agreed reasonably with predications from the Maxwell inclusion model over a range of void contents from 0 to 50%. The state of sorbed water was examined using mass balance calculations and DSC analysis. Only 6-8% of the void volume is occupied by water at saturation. Absorbed water may be classified as free and bound water. For void-free specimens, only bound water was found. The medium and high void content specimens contained water in three states: free water, freezable bound water, and non-freezable bound water. The DSC results show that the proportions of free water and freezable bound water increase with increasing void content, while the content of non-freezable bound water decreased. Moisture induced swelling decreased with increasing void content. The swelling is attributed to the content of non-freezable bound water.

A crescente demanda de produtos florestais tem levado as empresas brasileiras que realizam reflorestamento com espécies do gênero Eucalyptus a uma busca por maior produtividade devido a sua utilização para celulose, papel e carvão. Um dos principais fatores limitante da produção agrícola é falta de água, que inibe vários processos fisiológicos nas plantas. Este trabalho teve por objetivo estudar os efeitos da deficiência hídrica sobre a fisiologia de plântulas de quatro espécies de Eucalyptus: E. citriodora, E. pellita, E. urograndis e E. grandis, visando obter informações sobre a susceptibilidade das plantas ao déficit hídrico na fase inicial de seu desenvolvimento que é um período crítico para a implantação de povoamentos florestais. As plântulas foram expostas a três regimes de irrigação, baseados na evaporação de um mini-tanque classe A com reposição de 100, 50 e 25 % da lâmina de água, das quais foram avaliadas em relação as trocas gasosas, fluorescência da clorofila a, conteúdo de clorofila e potencial de água foliar. Observou-se que as espécies de E.pellita e E. citriodora foram as mais tolerantes ao défict hídrico imposto pelo regime de 50% de reposição da lâmina de água. Entretanto o regime com 25% afetou as espécies de forma similar

The growing demand for forest products has led Brazilian reflorestation companies that work out reforestation with Eucalyptus to a search for higher productivity due to their use for cellulose, paper and chancoal. One of the most limiting factors for agricultural production is the water deficit, which inhibits several physiological process in plants. This work was aimed to study the effects of water deficit on the physiology of seedlings of four species Eucalyptus: E. citriodora, E. pellita, E. urograndis e E. grandis, looking for information about plants susceptibility at water deficit in the initial phase their of development with is a critical period for the installation of forest. The seedlings were exposed to three irrigation schemes, based on class A evaporation pan with replacement of 100, 50 and 25% of the water level, which were evaluated by gas exchange, chlorophyll fluorescence and content leaf water potential. It was observed that E. pellita and E.citrodora were more tolerant to level water imposed by the regime of 50% of replacement of the water depth. Meanwhile the regime with 25% effected the species so similar

▼ The large volume of water produced during the extraction of oil presents a significant problem due to the high cost of disposal in an environmentally friendly manner. On average, an estimated seven barrels of water is produced per barrel of oil in the US alone and the associated treatment and disposal cost is an estimated $5-10 billion. Besides making oil-water separation more complex, produced water also causes problems such as corrosion in the wellbore, decline in production rate and ultimate recovery of hydrocarbons and premature well or field abandonment. Water production can be more problematic during waterflooding in a highly heterogeneous reservoir with vertical communication between layers leading to unevenness in the flood front, cross-flow between high and low permeability layers and early water breakthrough from high permeability layers. Some of the different technologies that can be used to counteract this involve reducing the mobility of water or using a permeability block in the higher permeability, swept zones. This research was initiated to evaluate the potential effectiveness of the latter method, known as deep diverting gels (DDG) to plug thief zones deep within the reservoir and far from the injection well. To evaluate the performance of DDG, its injection was modeled, sensitivities run for a range of reservoir characteristics and conditions and an economic analysis was also performed. The performance of the DDG was then compared to other recovery methods, specifically waterflooding and polymer flooding from a technical and economic perspective. A literature review was performed on the background of injection profile control methods, their respective designs and technical capabilities. For the methods selected, Schlumberger's Eclipse software was used to simulate their behavior in a reservoir using realistic and simplified assumptions of reservoir characteristics and fluid properties. The simulation results obtained were then used to carry out economic analyses upon which conclusions and recommendations are based. These results show that the factor with the largest impact on the economic success of this method versus a polymer flood was the amount of incremental oil produced. By comparing net present values of the different methods, it was found that the polymer flood was the most successful with the highest NPV for each configuration followed by DDG.

▼ Increasing urbanisation and associated impervious surfaces have negative impacts on humans and the environment. Therefore, more resilient and sustainable stormwater management that mimics the natural predevelopment hydrology cycle to protect urban water sources and reduce urban flooding is required. Contributing to this approach, green roofs can partly compensate the loss of natural landscapes and mitigate runoff. Green roof plant selection has mostly been limited to species with the ability to survive extreme environmental conditions, typically Sedum species. However, green roofs with these species planted in monoculture may not be efficient in terms of rainfall retention. Selecting plants with water use plasticity and increasing substrate depth may improve green roof hydrological performance in these highly variable environments, without substantially introducing drought risk. To examine this, two experiments were conducted. The first, a 17-month controlled rainfall experiment, was examined in two studies: 1) to understand the overall effect of plant water use strategies and of the mixture of plants within water use plasticity on retention, and 2) to understand the mechanisms driving rainfall retention. The second experiment, a 27-month green roof field study, examined the effect of increasing substrate depth on rainfall retention and plant drought stress. Contrary to my initial hypotheses, plant species with water use plasticity did not always provide greater retention performance, compared with conservative succulent species. Retention performance of a plant mixture was dominated by key species and was not always greater than that of monocultures. The effects of plant treatment on retention performance were significant for medium and large rainfall events, but minor for small rainfall events. Rainfall characteristics and available storage of substrates before rainfall events strongly drove retention performance. Although the effects of ET were well understood and shown to be as the key factor for green roof retention, ‘Non-ET’ plant effects (i.e., the reduction in storage capacity, either via preferential flow, or roots occupying storage volume) can change the relative importance of ET. That is, the maximum storage capacity becomes a more important driver of available storage in the substrate compared with the ability of plants to deplete that stored moisture. Increasing substrate depth only marginally improved retention performance, however, deeper substrates significantly reduced the period of time plants were exposed to drought stress. The results showed that green roofs perform well for retention (average ~73% in total study period; average ~91% in per-event), particularly in warm and dry climates with a large proportion of small rainfall events. Selection of plants with water use plasticity and the use of mixtures was less important for improving retention than climate. However, when planting treatments were compared, root-induced preferential flow paths were shown to reduce the water storage…

▼ Water supply reservoirs are often subject to accelerated nutrient enrichment from urban sources. Cultural eutrophication due to such enrichment requires the development of efficient management and remediation strategies to protect drinking water sources. This study investigates the effects of using nitrate as part of a management strategy to control nutrient cycling in the Occoquan Reservoir in northern Virginia, USA. A novel aspect of the study is that the reservoir is part of an indirect potable reuse system where the source of nitrate is the product water from an advanced water reclamation facility (WRF). Field and laboratory studies showed that nitrate at a concentration greater than 1 mg/L N was effective in controlling the release of phosphorus, iron, and manganese from the sediments after the depletion of oxygen from the hypolimnetic waters of the reservoir. However, when the nitrate concentration above the sediment-water interface was less than 1 mg/L N, phosphorus, iron, and manganese release from the sediments was evident. Experiments revealed that the presence of nitrate decreased sediment ammonium release, but did not completely prevent it during anoxic periods. Results also showed that changes in the effective depth (ED) value along the length of the reservoir promoted higher denitrification rates in the upper reaches of the reservoir, thereby decreasing the downstream transport of nitrate. During periods of hypolimnetic anoxia, a nitrate-N input from the WRF of at least 10 mg/L N is needed to maintain an oxidized environment above the sediment-water interface. Therefore, decreasing the nitrate input to the reservoir will likely result in the deterioration of the surface water quality in the reservoir. Finally, the ED concept was proven to be an effective method to simulate different segments of the reservoir in laboratory-scaled experiments. Similarities between the field and laboratory results suggests that the environment that existed in the waters of the reservoir was closely replicated in the experimental setup, and provides confidence that laboratory results can be extrapolated to natural reservoir conditions.

Face à la pénurie de granulats alluvionnaires, l’utilisation de granulats issus de roches massives est devenue systématique pour la formulation de mortiers ou de bétons. Ainsi, la part des granulats concassés de roche massive a fortement augmenté lors de la dernière décennie alors que, pour des raisons normatives dans le domaine du recyclage, la part des granulats recyclés est amenée à le faire lors de la prochaine. La relation de ces granulats avec l’eau et, plus particulièrement, de leur fraction fine est beaucoup plus complexe que celle de leurs prédécesseurs, les granulats naturels alluvionnaires. Ces particules plus poreuses sont à même d’absorber des quantités d’eau plus importantes mais elles le font, par ailleurs, avec des cinétiques peu comparables. Pour contrôler l’absorption d’eau des granulats poreux, il est d’usage de compenser l’absorption des granulats au moment de la formulation après avoir caractériser les granulats. Cependant, l’angularité et la rugosité de surface des granulats recyclés imposent d’adapter les normes actuelles utilisées pour la caractérisation de granulats alluvionnaires. Dans ce travail de thèse, nous proposons de mettre en place différentes méthodes pour caractériser les granulats concassés et recyclés. Dans un premier temps, nous étudions la méthode consistant à déterminer l’absorption d’eau par séchage de granulats saturés et nous montrons que cette méthode est plus particulièrement adaptée dans le cas de granulats de morphologie anguleuse. En effet, nous montrons que la baisse du taux de séchage est bien associée au passage de l’évaporation inter-grains à l’évaporation de l’eau intra-grains et que cette méthode permet une bonne estimation de l’absorption de granulats fins poreux. Dans un second temps, nous montrons que l’étude de la perte de rhéologie d’un mortier, à travers des mesures d’étalement, permet de déterminer l’absorption d’eau de granulats poreux. Nous étendons, dans une deuxième partie, notre étude aux conséquences inhérentes à l’utilisation de ces granulats dans un nouveau matériau cimentaire. Nous observons, à l’aide de la spectrométrie RMN, les transferts d’eau de la pâte de ciment fraîche vers les granulats poreux. Nous observons que l’absorption d’eau de granulats recyclés peut être réduite dans une pâte de ciment fraîche par rapport à l’absorption dans l’eau pure. Nous montrons que le prétraitement thermique généralement imposé en laboratoire aux granulats recyclés impacte la microstructure par la déshydratation d’hydrates tels que les aluminates et les silicates de calcium. En présence de la solution interstitielle de la pâte de ciment, la réhydratation des anhydres peut amener à une précipitation de calcium dans la porosité qui limite l’absorption par colmatage des pores
