Abstract:

This study evaluated the potential use of an antimicrobial packaging system in combination with electron beam irradiation to enhance quality of fresh produce. Irradiated romaine lettuce up to 3.2 kGy showed negligible (p > 0.05) changes in color, but texture and sensory attributes were less acceptable with increased dose. We established the antimicrobial effectiveness of various active compounds incorporated into the low-density polyethylene (LDPE)/polyamide films to increase radiation sensitivity of surrogate bacteria (Listeria innocua and Escherichia coli). All films showed inhibition zones

Abstract:

This study was done in order to assess the incidence of Staphylococcus species from milk of cows with subclinical mastitis and their antimicrobial sensitivity in some selected antibiotics and Usnea barbata lichen extracts. The study was conducted in two different commercial dairy farms. Staphylococcus species isolates were identified using several biochemical tests which included Gram’s staining test, catalase test and oxidase test. A commercial API® staph kit (bioMerieux, France) was used to confirm the bacterial organisms to their species level. The antimicrobial sensitivity of individual sp

Abstract:

Current-to-pressure (I/P) converters are pneumatic devices which provide precise control of pressure in various industries – for example these devices are often used in valve positioner systems (typically found in the oil and gas industry) and tensioning systems (typically used in the packaging industry). With an increasing demand for such devices to operate in harsh environments all by delivering acceptable performance means that Current-to-pressure converters need to be carefully designed such that environmental factors have no or minimal effects on its performance.

Intravenous injection of substance P (SP) stimulates sympathetic ganglia to evoke a greater increase in renal sympathetic nerve activity, heart rate (HR) and blood pressure (BP) in hypertensive than normotensive rats due to upregulation of the NK1 receptor. These experiments were designed to determine the cellular basis for the enhanced ganglionic responsiveness to NK1 agonists in spontaneously hypertensive rats (SHR) in comparison to their normotensive counterparts, Wistar-Kyoto rats (WKY). Studies were also conducted to determine whether the increased ganglion responsiveness to SP in SHR i

All these functions are possible despite its relatively simple structure, due to its capacity to interact with different types of biological membranes.

Abstract:

By employing cross-country variations in the adoption of the Basel I and II capital Accords, we examine how different designs of the risk-sensitivity of capital requirements influence bank business choices. We show that the move to the Basel II regime has not amplified the trends found for the Basel I Accord in the form of a reduction in total lending growth (asset substitution), and increases in lending risk (cherry picking) and noninterest income activities (activity substitution). In fact, Basel II has led to a reduction in bank exposure to non-interest income and, at least in the cas

Abstract:

The main focus of this work is on the non-Newtonian effects on the inertial instabilities in shear flows. Both inelastic (Carreau) and elastic models (Oldroyd-B and FENE-P) have been employed to examine the main features of the non-Newtonian fluids; shear-thinning, shear-thickening and elasticity. Several classical configurations have been considered; flow past a circular cylinder, in a lid-driven cavity and in a channel. We have used a wide range of tools for linear stability analysis, modal, non-modal, energy and sensitivity analysis, to determine the instability mechanisms of the non-Newton

Abstract:

A produção de etanol nas destilarias brasileiras é baseada na atividade fermentativa da levedura Saccharomyces cerevisiae que utiliza o caldo da cana-de-açúcar e/ou o melaço como substrato. Bactérias contaminantes da fermentação alcoólica competem com as leveduras pelos açúcares, afetando o rendimento do sistema produtivo e, consequentemente, causando perdas econômicas significativas às usinas. Biofilmes formados nos tanques de fermentação alcoólica agem como reservatórios de bactérias, contribuindo para contaminações persistentes e de difícil controle. Os biofilmes proporcionam aos seus habit

O fungo filamentoso Neoscytalidium dimidiatum é um microrganismo saprofítico e fitopatogênico, encontrado no solo e vegetação de regiões de clima tropical e subtropical. N. dimidiatum var. hyalinum e N. dimidiatum estão envolvidos em infecções superficiais de pele e unha sendo que a espécie produtora de melanina, N. dimidiatum, está associado preferencialmente a infecções profundas sugerindo que a espécie variante não produtora de melani

Abstract:

My PhD dissertation deals with statistical methods for cut-point finding for continuous biomarkers. Categorization is often needed for clinical decision making when dealing with diagnostic (or prognostic) biomarkers and a dichotomous or censored failure time outcome. This allows the definition of two or more prognostic risk groups, or also patient’s stratifications for inclusion in randomized clinical trials (RCTs). We investigate the following cut-point finding methods: minimum P-value, Youden index, concordance probability and point closest to-(0,1) corner in the ROC plane. We compare them
