Abstract:

Drought conditions and wildfires can induce soil water repellency. Precipitation shifts are expected to exacerbate drought and wildfire in regions such as the southeastern United States, making it critical to understand how repellency affects water exchange processes in soil. The objectives of this dissertation were to 1) quantify the water vapor sorption dynamics of two clay minerals in which water repellency was induced; 2) identify if and for how long wildfires in humid hardwood forests induce water repellency, 3) evaluate if organic carbon content and hydrophobic functional groups explain

Abstract:

The aim of this thesis is to increase our knowledge and understanding of trace water concentrations in nominally anhydrous minerals (NAMs). Special focus is put on the de- and rehydration mechanisms of clinopyroxene crystals in volcanic systems, how these minerals can be used to investigate the volatile content of mantle rocks and melts on both Earth and other planetary bodies (e.g., Mars). Various analytical techniques for water concentration analysis were evaluated. The first part of the thesis focusses on rehydration experiments in hydrogen gas at 1 atm and under hydrothermal pressures from

The deposit consists of both manganese rich and manganese poor iron ore. The purpose of this study is to investigate the controlling factors for manganese content in both magnetite and surrounding silicate minerals, especially when garnets is present.

Abstract:

Coal particles with different densities have different mineral and maceral compositions and this affects the gasification reaction rates, especially in coals with high ash contents. This study involved the characterization of six Highveld coals (coals A – F) as well as a coal blend (coal G) consisting of several of these single- source coals in terms of chemical, maceral, mineral and structural properties. This initial characterization was supported by the evaluation of the pyrolysis gas compositions (at 600ºC) that can be obtained from the seven parent coals. The second part of this study in

The first method was ageing of a solid adhesive-screed system at elevated temperature. It was done in order to evaluate the effect of contact between adhesives and screed in different adhesive-

Abstract:

The durability of reinforced concrete structures derives from the protective effect provided by the concrete cover over the steel rebars. When the passivation of the steel is compromised, the whole structure is liable to corrosion phenomena, whose rate of propagation is mainly controlled by the electrical resistivity of the concrete between the anode and cathode and by the availability of oxygen at the cathode. The electrical resistivity of concrete is highly dependent on its physical and chemical characteristics. This study aimed at to investigate the influence of the content of rice husk ash

Abstract:

AIM: Bone changes in size and density in response to different levels of stress. Alterations to bone mineral density (BMD) appear to occur in a site specific manner. Even though BMD has been examined in many populations there is a paucity of data looking at strength-power athletes, such as throwers. Therefore, the purpose of this study was to examine the BMD of a group of USA Division I collegiate throwers (e.g. shot put, discus, etc.). METHODS: Seven throwers (4 males; 3 females) who were 19.0 ± 0.9 years had their BMD compared to an age matched control group (n=14; 8 women and 6 men) and nor

Abstract:

The objectives of this research were to evaluate non-invasive measures of bone mineral content (BMC) and bone mineral density (BMD) as rapid, on-farm tools to assess phosphorus (P) status in dairy cows. In addition, the effects of parity and stage of lactation on measures of BMC of the fused 3rd and 4th metacarpal bone and of caudal vertebrae 14 and 15 were assessed. The caudal vertebrae and right front metacarpal (sample pairs) were excised from 107 Holstein cull cows following slaughter. Parity, age, and days in milk (DIM) of the donor animal were obtained for 43 pairs of samples. Samples we

Abstract:

Bone mineral content (BMC) and bone mineral density (BMD), measured by dual x-ray absorptiometry are used clinically to diagnose osteoporosis and estimate risk for fragility fractures. Bone mineral explains up to 70% of bone strength; however, it does not take into account bone geometry. Mechanical Response Tissue Analysis is a method of non-invasively measuring the bending stiffness (EI) of bone which is determined by the product of Young's modulus of elasticity (E) and the areal cross sectional moment of inertia (I). The aim of the current study was to determine if high intensity strength tr

Abstract:

High body weight seems protective of bone mass, specifically bone mineral content (BMC) and bone mineral density (BMD), thereby reducing the risk of osteoporosis. Cognitive eating restraint (CER), diet composition, and the satiety hormone, leptin, produced by adipocytes, are associated with body mass and may also influence bone mass. Few studies have examined these relationships. To investigate the relationship between leptin and CER score, 36 premenopausal, healthy weight women, as defined by body mass index (BMI) of 18-25 kg/m<sup>2</sup>, aged 18-25 years were studied. Women were catego

Abstract:

U ovom istraživanju je utvrđen uticaj primjene biostimulatora na morfolo&scaron;ke i fiziolo&scaron;ke parametre rasta i razvoja, te na mineralni sastav kod sezonskog cvijeća, kadifice i stalnocvjetajuće begonije.  Uticaj biostimulatora je ispitan kroz tri godine istraživanja u za&scaron;tićenom prostoru i na otvorenom polju. Istraživanje je provedeno na mladim biljkama-rasadu prije presađivanja i na odraslim biljkama. U fazi rasada primjenjen je biostimulator Radifarm, a u fazi odraslih biljaka primjenjeni su biostimulatori Megafol, Kendal i Viva.  Tretman sa primjenjenim biostimula
