Retrospective Theses and Dissertations 1995 Modulation of [gamma]-aminobutyric acid (GABA) type A receptor-mediated responses in spinal dorsal horn neurons by [mu]-opioid receptor agonists and Ca²+/calmodulin-dependent protein kinase and Monte Carlo simulation of the GABAergic synaptic transmission Wang, Rong, "Modulation of [gamma]-aminobutyric acid (GABA) type A receptor-mediated responses in...

This study examined the potential for coal mine roof bolter dust to be a source of a worker’s exposure to respirable quartz. For the models of roof bolter studied, the dust from bolt hole drilling is collected by a dry vacuum exhaust system. The collected dust-laden air passes through a cyclone size-separator (pre-cleaner) and into a collector box containing two additional cyclones and a filter...

THE basic outlines of most of the hydrous layer silicate structures were determined during the 1930's. Present escalating interest in obtaining additional detail is indicated by (a) publication of over twenty structural refinements (2-D or 3-D) during 1954-64, (b) publication of a t least nine structures in 1965 or early 1966, and (c) personal communicat ion tha t a t least fifteen additional r...

Clay minerals are one of the most utilized among non-metals. These hydrous aluminum silicates with a layer (sheet-like) structure. Kaolin is aluminosilicate mineral thin platelet extensively used in paper, paint, and many other industries. Wet processing kaolin will not be sustainable over long term because global freshwater resources becoming scarce. Hence, process necessary that does consume ...

BACKGROUND The inter-pregnancy period is considered a teachable moment when women are receptive to weight- management guidance aimed at optimising pregnancy outcome in subsequent pregnancies. In population based studies inter-pregnancy weight change is associated with several adverse pregnancy outcomes but the impact on placental size is unknown. METHODS The association between inter-pregnanc...

9 Low enthalpy geothermal energy is a renewable resource that is still underexploited nowadays, in 10 relation to its potential for development in the society worldwide. Most of its applicabilities have 11 already been investigated, such as: heating and cooling of private and public buildings, roads defrost, 12 cooling of industrial processes, food drying systems, desalination. 13 One of the ma...

As the incidence of osteoarthritis and other degenerative joint conditions continues to grow, rehabilitation via tissue engineering is becomingly increasingly attractive as an alternative to traditional surgical interventions. Chapters 2 and 3 of this thesis are specifically concerned with cartilage tissue engineering, while chapter 4 is relevant to bone and osteochondral tissue engineering. Th...

One of the most undesirable consequences induced by blasting in open-pit mines and civil activities is flyrock. Furthermore, production oversize boulders creates many problems for continuation work usually imposes additional costs on project. In this way, breakage associated with throwing small fragments particles at high speed, which can lead to serious risks human resources infrastructures. H...
