Doctor of Philosophy / Department of Agronomy / DeAnn R. Presley / The abandoned lead (Pb) and zinc (Zn) mines in the Tri-State Mining District of Kansas, Missouri, and Oklahoma have left a legacy of environmental contamination. The waste materials are highly polluted, not only with Pb and Zn, but also cadmium (Cd), which often co-occurs geologically with Zn. The District includes Galena, Kansas, where mines operated between 1876 and 1970. Because limited information exists concerning these mines, three studies were done to characterize them and to investigate a way to remediate the mine waste materials. In the first study, the physical characteristics of the mine waste materials were determined. Plots at Galena that had been established by researchers in May 2006 were sampled in November 2014, 8.5 years after they had received amendments (combinations of compost, lime, and bentonite). Water content, bulk density, infiltration rate, unsaturated hydraulic conductivity, aggregate stability, and particle size distribution were determined. The physical characteristics were highly variable, and the amendments added 8.5 years earlier had no effect on them, except the wind erodible fraction (fraction <0.84 mm in diameter) which was low on treatments that contained bentonite. Because biosolids had never been applied to the mine waste materials at Galena for remediation, an experiment was done to see their effect on plant growth and availability of heavy metals. In 2014 the plots established in 2006 were sampled and a greenhouse study was set up with sudex [Sorghum bicolor (L.) Moench x S. Sudanese (P.) Staph]. Plants grew in the mine waste materials with and without biosolids, and 110-111 days after planting the roots, shoots, and heads with grain were harvested and analyzed for heavy metals. At the same time, the mine waste materials were analyzed for heavy metals, organic carbon (C), nitrogen (N), and phosphorus (P). Plants grew better with biosolids than without biosolids, and only the plants grown with biosolids produced heads . Plants grown without biosolids were stunted and showed severe heavy metal toxicity. Organic C and P were increased in the mine waste materials after the addition of biosolids. Thus, the biosolids increased organic C and P, and they apparently made the heavy metals less available for plant uptake. Many studies have shown the importance of attic dust in documenting metal pollution from a mine. Attic dust in Galena had never been studied, so in a third experiment, 14 dust samples in Galena were collected from interiors (attics and one basement) of nine different buildings using two methods: sweeping with a brush and vacuuming. Dust samples were analyzed for heavy metals (Cd, Cu, Fe, Mn, Ni, Pb, and Zn), mineralogy using X-ray diffraction (XRD), scanning electron microscopy (SEM) in conjunction with energy dispersive spectroscopy (EDX), and particle size. Concentrations of Cu, Fe, Mn, Ni, and Zn in the dust were higher than in the mine waste materials. The results from XRD agreed with those from the SEM-EDX analysis. About 10% of each dust sample contained particulate matter (PM) with a diameter of less than 10 μm (PM₁₀), which is a health concern.

Adper™ Scotch™ Bond Multi Purpose, Adper™ Single Bond (3M ESPE), and Clearfil SE Bond (Kuraray) adhesive systems were modified with concentrations of 0 (control), 1, 2 and 5% F-18 bioactive glass. In addition, the distribution and dispersion of bioactive glass particles were verified by scanning electron microscopy (SEM). For the degree of conversion, absorption spectra of cured and uncured adhesive systems were obtained. For the wettability test, adhesive systems modified or not were dispensed on the dentin surfaces of bovine teeth, and the contact angles were measured by goniometer. For the microshear test, specimens were made in composite resin on bovine substrate, on which adhesive systems, modified or not, were applied, and the adhesive strength tests were done after 24 hours. The failure pattern of the specimens was analyzed in a stereoscopic magnifying glass and by scanning electron microscopy (SEM). The results were obtained and analyzed by ANOVA Variance Analysis (2 factors) with Tukey test. It was observed that there were no differences between the control and modified groups (p> 0.05). The predominant failure pattern was adhesive. It was concluded that the addition of F-18 bioactive glass microparticles did not in... (Complete abstract click electronic access below) / Mestre

A madeira é um material de origem biológica, renovável, com papel importante no ciclo do carbono, que contribui para o desenvolvimento sustentável. As madeiras tropicais brasileiras são apreciadas na indústria da construção civil em peças estruturais, componentes de edificação e mobiliário. A melhor utilização da matéria-prima nos diversos processos depende do conhecimento das suas propriedades, e nesse aspecto, os estudos sobre estabilidade dimensional são escassos, em sua maioria, desenvolvidos para coníferas do hemisfério Norte. Este trabalho tem como objetivo geral aprofundar o estudo da estabilidade dimensional, trabalhando com propriedades físicas de madeiras tropicais brasileiras, com ênfase nas densidades, ponto de saturação das fibras, retratibilidade e inchamento. Utilizando madeira de quinze espécies tropicais brasileiras, foram realizados ensaios, de acordo com a NBR 7190/97 para determinar: densidade aparente 0% e 12% de umidade, densidade básica, ponto de saturação das fibras, retração, inchamento, coeficiente de anisotropia, coeficiente de retratibilidade volumétrica e coeficiente de inchamento volumétrico. Investigaram-se as relações entre as propriedades determinadas de modo a poder inferir sobre: a estabilidade dimensional baseando-se nas densidades; as precisões de relações desenvolvidas em pesquisas correlatas. Além disso, foi desenvolvida (e investigada sua precisão, ao nível de significância 5%) uma relação entre densidade básica e densidade aparente via retratibilidade/inchamento. De acordo com os resultados, o melhor coeficiente de determinação ajustado atingido na tentativa de relacionar densidades com os parâmetros da estabilidade dimensional foi 19,58% indicando que a densidade não é um bom estimador da estabilidade dimensional da madeira. Algumas das relações desenvolvidas em pesquisas correlatas não foram consideradas válidas, de acordo com a análise estatística. Para a relação desenvolvida no presente trabalho, embora a mesma apresente média e coeficiente de variação próximos aos dos resultados experimentais, a análise de representatividade não confirmou sua significância. / Wood is an organic and renewable material, with important role in carbon cycle, which contributes to sustainable development. Brazilian tropical woods are considered in building industry in structural ant other components and in furniture. The better use of raw materials in different processes depends on knowledge of their properties and, in this respect, studies of dimensional stability are scarce, mostly developed for Northern Hemisphere conifers. This work aims to extend the study of dimensional stability, now working with physical properties of Brazilian tropical woods, emphasizing densities, fiber saturation point; shrinkage and swelling. Using wood of fifteen Brazilian tropical species, tests were carried out, according to NBR 7190/97 to determine: density (0% and 12% moisture content); basic density; fiber saturation point; shrinkage; swelling; anisotropy coefficient; volumetric shrinkage coefficient; and volumetric swelling coefficient. Correlations between certain properties were investigated in order to be able to infer: dimensional stability based on densities; precision of relationships developed in related research. Furthermore, it was developed (and investigated their accuracy, 5% significance level) a relationship between specific gravity and bulk density via shrinkage/ swelling. According to results, the best determination coefficient, obtained in attempt to correlate density with parameters of dimensional stability, was 19.58%. This indicates that density is not a good estimator of dimensional stability for tropical wood. Based on statistical analysis, some of the relationships developed in related researches were not considered valid. For the relationship developed in this research, although it presents average and coefficient of variation close to experimental results, analysis of accuracy did not confirm its significance.

Organic agriculture became a market in expansion, with great perspectives for the producer. The organic coffee is a differentiated product, of bigger added value, whose market has grown and if fortified throughout the years. Although the coffee to be an old culture, studies on its physical properties are limited and dispersed. The knowledge of the physical characteristics of the products harvested in Brazil is essential for the project, construction and operation of cleanness equipment, drying, classification, storage and industrialization, as well as for the existing equipment adaptation already aiming at to the biggest income and rationalization of energy use. In such a way, this work had as objective to determine some physical properties of grains of organic and conventional coffee. Sphericity and circularity, granular specific mass, porosity and terminal speed had been determined. The work was lead in the laboratories of the UNIOESTE -Cascavel. They had been used supreme of organic and conventional coffee (Coffea arabica, L.) in the stadium coconut, gotten next to the Emater. From the gotten results, it can be concluded that the measure of the ortogonals axles did not present significant difference, when comparative the varieties and the types of treatments. Fruits of coffee in the types organic and conventional and the variety, had not presented difference in the circularity determination. The found values of apparent and real specific mass had been similar to the described ones for other authors, however, comparing the organic coffee with the conventional, it did not have difference of values. The Catuaí variety organic treatment, presented greater average value of porosity, however significant difference between organic and conventional coffee in the two analyzed varieties was not observed. The organic treatments had presented, in the determination of terminal speed, values about 9% superiors to the conventionals / O café é um dos principais ítens de exportação juntamente, com o açúcar e o algodão. A agricultura orgânica tornou-se um mercado em expansão, com grandes perspectivas para o produtor. O café orgânico é um produto diferenciado, de maior valor agregado, cujo mercado tem crescido e se fortalecido ao longo dos anos. Apesar do café ser uma cultura antiga, estudos sobre suas propriedades físicas são limitados e dispersos. O conhecimento das características físicas dos produtos colhidos no Brasil é essencial para o projeto, construção e operação de equipamentos de limpeza, secagem, classificação, armazenagem e industrialização, bem como para a adaptação de equipamentos já existentes visando ao maior rendimento e racionalização de uso de energia. Desta forma, este trabalho teve como objetivo determinar algumas propriedades físicas de grãos de café orgânico e convencional. Foram determinadas a esfericidade e circularidade, massa específica granular, porosidade e velocidade terminal. O trabalho foi conduzido nos laboratórios da UNIOESTE - Cascavel-PR. Foram utilizados grãos de café (Coffea arábica, L.) orgânico e convencional no estádio coco, obtidos junto à Emater. A partir dos resultados obtidos, pode-se concluir que a medida dos eixos ortogonais não apresentou diferença significativa, quando comparadas as variedades e os tipos de tratamentos. Frutos de café nos tipos orgânico e convencional e a variedade, não apresentaram diferença nas determinações de circularidade. Os valores de massa específica aparente e real encontrados foram semelhantes aos descritos por outros autores, no entanto, comparando-se o café orgânico com o convencional, não houve diferença de valores. A variedade Catuaí tratamento orgânico, apresentou maior valor médio de porosidade, contudo não observou-se diferença significativa entre café orgânico e convencional nas duas variedades analisadas. Os tratamentos orgânicos apresentaram, nas determinações de velocidade terminal, valores cerca de 9% superiores aos convencionais

<p>Zemlji&scaron;te i voda predstavljaju važne prirodne resurse koji su čovekovim kori&scaron;ćenjem bitno&nbsp;izmenjeni. Zemlji&scaron;te predstavlja neobnovljiv resurs čijom antropogenizacijom često dolazi do&nbsp;degradacije. Nestručnom ili nesavesnom primenom navodnjavanja uglavnom dolazi do pojave&nbsp;neželjenih posledica na zemlji&scaron;tu. U Vojvodini postoje i zemlji&scaron;ni i klimatski uslovi koji&nbsp;mogu prouzrokovati zaslanjivanje zemlji&scaron;ta u sistemima za navodnjavanje, naročito kada je&nbsp;voda za navodnjavanje mineralizovana. Pravilno (racionalno) navodnjavanje podrazumeva<br />dobro poznavanje zemlji&scaron;nih i klimatskih uslova područja i biolo&scaron;kih karakteristika gajenih&nbsp;biljaka. Kada se govori o promenama na zemlji&scaron;tu koje navodnjavanje može da izazove, treba&nbsp;odvojiti direktan uticaj vode i navodnjavanja od dejstva agrotehnike i ostalih pratećih činilaca&nbsp;i uslova.<br />Cilj istraživanja bio je da se utvrdi da li je dugogodi&scaron;nje navodnjavanje, u uslovima intenzivne&nbsp;proizvodnje povrća, uticalo na promenu morfolo&scaron;kih, vodno fizičkih i hemijskih svojstava&nbsp;karbonatnog černozema. Ukoliko se primenjuje racionalno navodnjavanje, uz uvažavanje&nbsp;hidropedolo&scaron;kih osobinama zemlji&scaron;ta i biolo&scaron;kih osobenosti gajenih biljaka, pretpostavka je&nbsp;da na ispitivanom zemlji&scaron;tu tipa černozem neće doći do degradacije in situ.<br />Istraživanja su obavljena na Oglednom polju Instituta za ratarstvo i povrtarstvo, Novi Sad, u&nbsp;Odeljenju za povrtarstvo na Rimskim &scaron;ančevima. Za potrebe analiza, otvoreno je osam&nbsp;pedolo&scaron;kih profila do dva metra dubine, četiri na zemlji&scaron;tu koje se u kontinuitetu navodnjava&nbsp;oro&scaron;avanjem od 1946. godine i četiri na zemlji&scaron;tu koje nikada nije navodnjavano. Za&nbsp;navodnjavanje je kori&scaron;ćena voda iz kopanih bunara. Za potrebe laboratorijskih istraživanja,&nbsp;uzeti su uzorci u poremećenom i prirodnom, neporemećenom stanju iz sredine utvrđenih&nbsp;genetičkih horizonata, kao i uzorci vode za navodnjavanje. Analizirani su fizička, vodno&nbsp;fizička i hemijska svojstva zemlji&scaron;ta, kao i hemijska svojstva vode za navodnjavanje,&nbsp;standardnim metodama koje su primenjuju za ovu vrstu istraživanja, kao i savremenim svetski&nbsp;priznatim metodama. Podaci su obrađeni metodom analize varijanse, a testiranje razlika&nbsp;između aritmetičkih sredina obavljeno je pomoću Dankanovog testa za nivo značajnosti 5%.<br />U cilju realnog sagledavanja uticaja navodnjavanja na vodno fizička i hemijska svojstva&nbsp;ispitivanog zemlji&scaron;ta, kori&scaron;ćena je i numerička multivarijantna (claster) metoda za simultanu&nbsp;analizu većeg broja podataka.vrednosti su ispod<br />graničnih vrednosti koje ukazuju da je u zemlji&scaron;tu do&scaron;lo do procesa zaslanjivanja.<br />Na osnovu rezultata istraživanja uočava se blagi trend pogor&scaron;anja hemijskih svojstava&nbsp;zemlji&scaron;ta pod uticajem navodnjavanja, te se stoga predlaže periodična kontrola kvaliteta, ne&nbsp;samo vode za navodnjavanje, nego i zemlji&scaron;ta. Dobijeni rezultati i zaključci predstavljaju&nbsp;osnovu za preduzimanje potrebnih mera u cilju očuvanja kvaliteta zemlji&scaron;ta.<br />Dobijeni rezultati istraživanja su pokazali da je do&scaron;lo do pogor&scaron;anja vodno fizičkih svojstva&nbsp;černozema, koje nije posledica navodnjavanja već drugih antropogenih i prirodnih faktora.<br />Utvrđeno je i blago pogor&scaron;anje hemijskih svojstava zemlji&scaron;ta kao posledica navodnjavanja&nbsp;zaslanjenom vodom. Ustanovljeno je povećanje pH vrednosti zemlji&scaron;ta, veći sadržaj kalcijum&nbsp;karbonata, usled navodnjavanja tvrdom vodom, i manji sadržaj humusa usled povećane&nbsp;mikrobiolo&scaron;ke aktivnosti i brže mineralizacije organske materije u uslovima povoljne&nbsp;vlažnosti zemlji&scaron;ta. Pod uticajem navodnjavanja, do&scaron;lo je do povećanja količine soli u&nbsp;zemlji&scaron;tu usled kori&scaron;ćenja zaslanjene vode za navodnjavanje.

In<br />Vojvodina there are soil and climate prerequisites that can cause soil salinization in irrigation<br />systems, especially irrigation water is saline. Correct (rational) irrigation means good<br />understanding of soil and climatic conditions of the area and the biological characteristics of<br />cultivated plants. Direct impact of water and irrigation on soil should be distinguished from<br />the effects of agricultural technology and other factors and conditions.<br />The aim of this study was to determine whether long-term irrigation, in intensive vegetable<br />production, caused the change of morphological, hydro physical and chemical properties of<br />carbonate chernozem. If rational irrigation is applied, in respect to hydropedological soil<br />properties and biological characteristics of cultivated plants, the assumption is that the<br />investigated chernozem soil will not show signs of degradation.<br />Investigations were carried out at the Experimental Field of the Institute of Field and<br />Vegetable Crops, Novi Sad, in the Department of Vegetable Crops. For the purpose of<br />analysis eight soil profiles were dug up to two meters deep, four on land that is irrigated by<br />sprinkling continuously since 1946 and four on land that has never been irrigated. Water for<br />irrigation was from the wells. For the purposes of laboratory tests, disturbed and undisturbed<br />soil samples were taken from the mid-determined genetic horizons, as well as irrigation water<br />samples. Physical, water physical and chemical soil properties and chemical properties of<br />irrigation water were analyzed by standard methods that are used for this type of research, as<br />well as the modern world-recognized methods. Data were analyzed using analysis of variance<br />and Duncan&#39;s LSD test for significance level of 5%. In order to objectively determine the<br />impact of irrigation on water physical and chemical properties of soil, multivariate numerical<br />(claster) method for the simultaneous analysis of large number of data was also used.<br />The results showed that there was deterioration in water physical properties of chernozem,<br />which, however is not the result of irrigation, but other anthropogenic and natural factors. It<br />was also found slight deterioration of chemical properties of the soil as a result of the<br />irrigation with saline water. It was found an increase in soil pH, higher content of calcium<br />carbonate due irrigation and lower humus content due to increased microbial activity and<br />faster mineralization of organic matter in favorable conditions of soil moisture. The increase<br />of salt amount was also found. Although there was a slight increase in salinity, total amount<br />of salt and ECe values are below the threshold for indicating the soil as saline.<br />The results indicate a mild trend of deterioration of chemical properties of soil under<br />irrigation. Therefore, periodic quality control is suggested, not only for irrigation water, but<br />also for the soil. The results and conclusions are the basis for taking the necessary measures in<br />order to preserve the soil quality.</p>

Novel plastic sheets and foams from vegetable oil-based monomers were produced. These new polyurethanes were synthesized from aromatic polyols, with erucic acid as the starting material. These monomers have the unique feature of containing an aromatic ring which was hypothesized to improve the rigidity of the polyurethane matrices and the overall physical properties of the plastics and foams. The benefits of the aromatic ring were proposed to be enhanced due to three terminal primary hydroxyl groups within the structure of the polyols. Reactions to produce hexasubstituted benzene derivatives containing alcohol groups in positions 1,2,4- and 1,3,5- around the benzene ring were suitably scaled up to provide amounts necessary for polyurethane production and characterization. These isomers (asymmetric and symmetric triols) were separated using chromatography. The pure triols were crosslinked with 4,4-methylenebis(phenyl isocyanate) into polyurethanes sheets (asymmetric and symmetric polyurethane respectively). The physico-chemical properties of these PUs were studied by Fourier transform infrared spectroscopy, x-ray diffraction,, differential scanning calorimetry dynamic mechanical analysis, thermogravimetric analysis coupled with Fourier transform infrared spectroscopy, and tensile analysis. The asymmetric polyurethane sheet and the symmetric polyurethane sheet differed in their glass transition temperatures and crosslinking densities. This variation could be explained by the differences in crosslinking densities, related to the increase in steric hindrance between adjacent hydroxyl groups of the asymmetric triol monomers. It was found that both polyurethanes had similar mechanical and thermal properties. Due to the similar properties of the asymmetric polyurethane and symmetric polyurethane sheets, the monomers were combined together in order to synthesize PU foams. The physical properties of these foams were studied by Fourier transform infrared spectroscopy, differential scanning calorimetry, dynamic mechanical analysis, scanning electron microscopy, thermogravimetric analysis and were analyzed for close cell content and compression strength. The effect of the benzene ring in the monomer structure on the physical properties of these new polyurethane foams was mainly compared with high density canola polyurethane foams previously investigated. It was demonstrated that the physical properties of polyurethane foams made with aromatic monomers are comparable to those made with aliphatic monomers when enhanced with glycerol. / Bioresource and Food Engineering

Lentils, one of the cool-season pulses, are consumed as a staple food in most developing countries. The demand for pulses in western societies is increasing because of its valuable nutritional quality and an increased awareness of health issues. Australia has a good reputation for producing clean low moisture legume products and could increase as market share of lentil production by identifying, developing and promoting good quality varieties.Lentils which are graded as good quality varieties must have a short and uniform cooking time, without 'hard to cook' seed, have the hull stay attached to the seed during cooking, and have a final acceptable taste, texture, flavour and appearance after cooking (Bhatty 1990). Cooking quality in this study is defined as the maximum force (N) that is required to compress the whole seed cooked product after cooking for a standard period of time. This study aims to develop an objective measurement to determine the cooking quality of lentils and thereby evaluates the relationships between lentil cooking quality and some of its physical and biochemical properties. Four cultivars used (Cassab, Digger, ILL 7180 and Matilda) were grown during 1999 at Mullewa and Pingaring, Western Australia. The relationship between the cooking quality of lentil and water absorption, seed size, seed coat thickness, phytic acid, mineral composition and initial moisture content was investigated.Texture measurement was carried out using the TA.XT2i meter as an alternative to the subjective method "Cooking time test". By comparing the cooking time determined by 'Cooking time test, 220 N was established and suggested as an optimal peak compression force to determine the adequate cooking time for lentils. Both methods showed that 35 minutes cooking time was adequate for red lentils (Cassab, Digger, and ILL 7180), and 45 minutes for green lentils ++ / (Matilda).Cooking significantly reduced the hardness of the seeds (R= - 0.752 to - 0.89) and promoted mineral leaching (P < 0.05). The interaction between environment and genotype had a significant effect on seed size, seed coat thickness, mineral composition (Phytic acid, Ne, K+, Mg2+, Ca2+ M+, Fe2+ and CU2+) and hardness (P< 0.05). Seed coat thickness did not correlated with this rate of water uptake and cooking quality. Growing environments had a greater influence on the cooking quality than genotypes. Lentils grown at Pingaring are generally had a higher in Phyti acid content, better mineral retention and were harder in texture than those grown at Mullewa.The results of this study implicated that the peak compression force (220 N) was identified as an indicator to determine the cooking time of lentil cultivars. Texture Profile Analysis (TPA) is a useful method to evaluate various texture characteristics (hardness, cohesiveness, chewiness, springiness, gumminess and adhesiveness) of lentil cultivars. Cooking quality of lentil is significantly affected by the effect of varieties and growing locations. However, not the various biochemical compositions (phytic acid and minerals) and the thickness of seed coat have no significant effect on the cooking quality of lentil.
