Multiple forms of carboxylesterases in the green bean (Phaseolus vulgaris L.) and pea (Pisum sativum L.)

Creator:: Veerabhadrappa, Patnagere Siddaveera Sheety
Abstract:: Esterase activity of an aqueous extract of the green bean was separated into fourteen bands, while aqueous extracted pea esterases revealed seven bands, by polyacrylamide-gel electrophoresis. The fourteen bands of bean esterase activity formed three groups; slow, intermediate and fast moving. α-Naphthyl acetate, propionate, and n-butyrate and AS naphthol acetate...

Exposure and health risk assessment for farmers occupationally exposed to chlorpyrifos in Sri Lanka and drinking water and house dust analysis for chlorpyrifos

Creator:: Aponso, G. Lalith M.
Abstract:: This study was designed to assess chiorpyrifos exposure of a group of farmers by determining internal dose associated with a given application of this insecticide. This involved the monitoring of urinary levels of 3,5,6 trichloro-2-pyridinol (TCP), the major metabolite of chlorpyrifos. Incidental exposure was evaluated by determining the levels of...

Relaxor characteristic and phase evolution of complex perovskite barium titanate bismuth zinc titanate ceramics

Creator:: Triamnak, Narit
Abstract:: Relaxor characteristic of the solid solution (1-x)BaTiO₃-(x)Bi(Zn₁/₂Ti₁/₂)O₃ (BTBZT) was investigated in this research. X-ray diffraction technique and Raman spectroscopy revealed the crystal structure of BT-BZT at various compositions. For compositions with x ≤ 0.08, the solid solutions exhibited clear tetragonal symmetry and transitioned to pseudo-cubic symmetry as the content of...

Addressing Data Resolution in Precision Agriculture

Creator:: Kelley, Jason
Abstract:: Irrigated agriculture constitutes the greatest consumptive water use globally, so that irrigation efficiency measures are an important part of global efforts to best utilize this limited resource. However, greater irrigation efficiency must be achieved while simultaneously maintaining or increasing crop yields and farming profitability. Incremental water use decisions are made...

The physiological effect of posture on cycling

Creator:: al-Haboubi, Muhammad
Abstract:: The objective of this research was to investigate the physiological effects of body posture on cycling. The familiar positions of bicycle riding have been the touring posture (hands stretched on top handlebar) and the racing posture (hands bent at the elbow, with the back horizontal). However, a relatively new stance...

Influence of vine vigor and shading in Pinot noir (Vitis vinifera L.) on the concentration and composition of phenolic compounds in grapes and wine

Creator:: Cortell, Jessica M.
Abstract:: In 2003 and 2004 vigor zones were delineated in two commercial vineyard sites based on vine growth variation to assess fruit and wine phenolic chemistry. In 2004, the effects of shading on the accumulation of phenolic compounds were also investigated. Model extractions were done from the shading experiment and the...

Optimal governor and excitation control of power systems with damping

Creator:: Yousif, Salah Mohammad, 1938-
Abstract:: The work in this thesis solves the problem of restoring a power system to its operating stable equilibrium point, following a transient disturbance, in minimum time without any oscillation. The idealized power system considered consists of cylindrical rotor generator connected to an infinite busbar with the following cases of control:...

The effect of vitamin B-6 deficiency on antitumor cytotoxic immune reactivity in mice

Creator:: Ha, Choonja
Abstract:: The effect of vitamin B-6 (VB6) deficiency in mice on host susceptibility to primary and secondary Moloney-sarcoma virus (MSV)-induced tumor growth, cytotoxic activities of T cells, antibodies and natural killer (NK) cells, and phagocytosis by macrophages was examined. Five- to six-week old female C57B1/6 mice were fed 20% casein diets...

Effect of controlled vitamin B-6 intake on in vitro lymphocyte proliferation and interleuken 2 production in young women

Creator:: Wang, Xu, 1954-
Abstract:: In two studies we tested the effect of vitamin B-6 (B-6) intake on in vitro lymphocyte, proliferation and IL-2 production in healthy young women. In Study I, 6 women were fed a constant diet containing 0.84 mg (4.96 μmols) of B-6 for 12 d, and 1.24 mg (7.33 μmols) and...

Inflorescence necrosis, ammonium, and evidence for ferredoxin-glutamate synthase activity in grape (Vitis vinifera L.)

Creator:: Creasy, Glen L.
Abstract:: Death of flower parts near bloom due to inflorescence necrosis (IN) is associated with high ammonium (NH₄⁺) concentration in flower clusters, shade, cool wet weather preceding bloom, and excessive vigor. Faults in NH₄⁺ assimilation are suspected to cause a rise in NH₄⁺ concentration to toxic levels in flower cluster but...
