3. TEMPERATURE AND HUMIDITY OF A SANDY LOAM SOIL CULTIVATED WITH MAIZE / TEMPERATURA E UMIDADE DE UM SOLO FRANCO ARENOSO CULTIVADO COM MILHO
Water is a key factor for crop yields, and causes major fluctuations in productivity, especially for maize cultivated in southern Brazil. Mulching the soil surface, temperature and soil moisture are factors closely linked and, when handled properly, can provide the increases crop yields. The soil water conservation is an important aspect for more stable and

4. Dinâmica e fatores-chave de mortalidade da broca do café (Hypothenemus hampei) / Dynamics and key factors of mortality of the coffee berry borer (Hypothenemus hampei)
The coffee berry borer Hypothenemus hampei (Ferrari) (Coleoptera: Scolytidae) is a pest of coffee and is present in almost all countries producing the crop causing losses of US$ 500 million a year. Despite its importance, nothing is known about her key factor and critical stage of mortality. Therefor, the objective of this study was to determine the critical

5. Crescimento regional : proposta e análise aplicada ao Brasil
This thesis proposes a new approach for Brazilian regional analysis. This study develops a basic dynamic growth model with factors mobility and its extensions in order to endogenize the total factor productivity (TFP) based on recent studies of economic development. The first chapter develops the basic model for regional growth analysis. It is considered an

9. Vitamin A deprivation results in reversible loss of hippocampal long-term synaptic plasticity
Despite its long history, the central effects of progressive depletion of vitamin A in adult mice has not been previously described. An examination of vitamin-deprived animals revealed a progressive and ultimately profound impairment of hippocampal CA1 long-term potentiation and a virtual abolishment of long-term depression. Importantly, these losses ar

10. Artificial gravity as a countermeasure to microgravity: a pilot study examining the effects on knee extensor and plantar flexor muscle groups
The goal of this project was to examine the effects of artificial gravity (AG) on skeletal muscle strength and key anabolic/catabolic markers known to regulate muscle mass. Two groups of subjects were selected for study: 1) a 21 day-bed rest (BR) group (n = 7) and 2) an AG group (n = 8), which was subjected to 21 days of 6° head-down tilt bed rest plus dail
