1. Modelling the growth of lactic acid bacteria at different temperatures
ABSTRACT Mathematical models are widely used to predict the shelf life of foods. Lactic acid bacteria (LAB), particularly Lactobacillus plantarum, Weissella viridescens and Lactobacillus sakei, are the main spoilage bacteria of refrigerated, vacuum-packed meat products, stored in modified atmosphere, and their growth determines the shelf life length of these

2. A novel voltage-mode CMOS quaternary logic design
This brief presents a novel kind of voltage-mode CMOS design that uses multiple threshold voltage transistors and three power supply lines to implement quaternary logic gates, showing lower power dissipation and using less area than the present voltage-mode quaternary circuits. Inverter, NMIN, and NMAX gates are simulated with the Spice tool using TSMC 0.18-

3. The ultra high energy extensive air shower longitudinal profile on the calorimetric energy calculus and primaries chemical composition studies / O perfil longitudinal de chuveiros atmosfericos extensos de altissimas energias no calculo da energia calorimetrica e no estudo da composição quimica dos primarios
Essa tese tinha como objetivo estudar o perfil longitudinal de chuveiros atmosféricos extensos de forma completa. Nós simulamos chuveiros atmosféricos utilizando o programa CORSIKA para diferentes primários e energias acima de 10 17 e V e procuramos relações entre vários parâmetros extraídos do perfil longitudinal, como Xmax, X0, Xmax - X0, FWHM ent

4. Bioadsorção de niquel por Acinetobacter baumannii e Pseudomonas aeruginosa isoladas de águas residuais industriais
Foi avaliada a capacidade de adsorção do Ni2+ por duas bactérias, Acinetobacter baumannii e Pseudomonas aeruginosa, em pH 4.5 com tempo de contato de 100 minutos. Isotermas de adsorção foram calculadas com as duas linhagens. Observou-se que, para ambas, o processo de adsorção está de acordo com o modelo fisicoquímico de Langmuir. A captação máxim

5. Estudo do fenomeno do colapso e reativação em atomos de tres e quatro niveis interagindo com campo de radiação quantizado
No presente trabalho é feito um estudo do fenômeno do colapso e reativação para átomos de três e quatro níveis. Foi utilizando para esta finalidade, a expansão do modelo tipo Jaynes-Cummings, que consiste da matematização da interação do campo de radiação com um átomo de dois níveis no interior de uma cavidade fechada, na aproximação de ond

6. RELATIONSHIPS BETWEEN INITIAL NUTRIENT CONCENTRATION AND TOTAL GROWTH1
Ecker, R. E. (Iowa State University, Ames), and W. R. Lockhart. Relationships between initial nutrient concentration and total growth. J. Bacteriol. 82:80–84. 1961.—The relationship observed between maximal attainable growth in a microbial population and initial concentration of limiting nutrient depends upon the parameter selected for measurement of gro

7. Pharmacokinetic-pharmacodynamic modeling of activity of ceftazidime during continuous and intermittent infusion.
We developed and applied pharmacokinetic-pharmacodynamic (PK-PD) models to characterize in vitro bacterial rate of killing as a function of ceftazidime concentrations over time. For PK-PD modeling, data obtained during continuous and intermittent infusion of ceftazidime in Pseudomonas aeruginosa killing experiments with an in vitro pharmacokinetic model were

8. Identification and regulation of 1,25-dihydroxyvitamin D3 receptor activity and biosynthesis of 1,25-dihydroxyvitamin D3. Studies in cultured bovine aortic endothelial cells and human dermal capillaries.
Because 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) has been shown to play roles in both proliferation and differentiation of novel target cells, the potential expression of 1,25(OH)2D3 receptor (VDR) activity was investigated in cultured bovine aortic endothelial cells (BAEC). Receptor binding assays performed on nuclear extracts of BAEC revealed a single class

9. Cultured psoriatic fibroblasts from involved and uninvolved sites have a partial but not absolute resistance to the proliferation-inhibition activity of 1,25-dihydroxyvitamin D3.
We examined the responsiveness of cultured dermal fibroblasts from biopsies of uninvolved and involved areas of skin from six patients with psoriasis to the cell-proliferation-inhibition activity of 1,25-dihydroxyvitamin D3 (1,25-(OH)2-D3). Cultured fibroblasts from age-matched controls responded to 1,25-(OH)2-D3 (at 0.01, 1, 10, and 100 microM) in a dose-de

10. Estradiol binds to a receptor-like cytosol binding protein and initiates a biological response in Paracoccidioides brasiliensis.
Paracoccidioidomycosis, a disease caused by Paracoccidioides brasiliensis, which is endemic to Latin America, is much more common in men than women, suggesting a role for hormonal factors. We recently showed that two other yeasts possess steroid binding proteins and postulated that these receptor-like molecules represented a mechanism by which the hormonal m
