The present article tried to establish dark/light preference in five different species of teleosts. We proposed, using the data obtained with this method zebrafishes (Danio rerio), Cardinal-tetras (Paracheirodon axelrodi), lambaris (Astyanax altiparanae), Nile tilapias (Oreochromis niloticus), guppies (Poecilia reticulata) and banded-knife fishes (Gymnotus carapo), that for dark environments is a reliable low-cost index anxiety/fear those species. A scototactic pattern exploration was found...

INTRODUCTION: Transforming growth factor beta 1 (TGFB1) and platelet-derived (PDGF) are the main cytokines related to hepatic fibrogenesis. METHODS: RNA isolated from platelets tissue of 43 HCV carriers was used for quantitative polymerase chain reaction determine TGFB1, PDGFA, PDGFB expression. RESULTS: The mRNA expression PDGFA in significantly lower group with advanced fibrosis than early-stage fibrosis. TGFB1 more frequently expressed tissue, which different PDGFB. CONCLUSIONS: A pathway...

Enthalpy, physical quantity indicating the amount of thermal energy in medium, is used by many researchers as an indicator comfort for humans and production animals. This has input variables dry bulb temperature, relative humidity air local barometric pressure. According to consolidated information temperature related animal homeostasis, it was possible establish enthalpy ranges swine, poultry cattle, considering pressure its variations, which not easily accessible situations field. Thus,...

A evapotranspiração (ET) é um parâmetro agrometeorológico importante para o manejo de irrigação, zoneamento agroclimático e gestão recursos hídricos. O modelo padrão estimativa, parametrizado pela Food and Agriculture Organization (FAO-56), Penman-Monteith utiliza saldo radiação como variável entrada, cujas medidas nem sempre estão disponíveis nas estações meteorológicas do país. busca por ajustes aos modelos alternativas a estimativa ET frequente na literatura, fim identificar que utilizem...

Physiological disorders during fruit storage are common, leading to important losses of marketable yield, and can be strongly affected by the mineral composition fruits at harvest. The present study was conducted for three years based on experimental data obtained from a fertilizer trial arranged as completely randomized block design, with replications, established in an orchard Portuguese Region Bairrada. aim evaluate influence nitrogen potassium fertilization yield Actinidia deliciosa...

Diffuse solar radiation is measured using a pyranometer positioned under the shadow of ring. The function ring to block direct radiation. However, also blocks portion diffuse radiation, and therefore, needs corrections. most well-known assembly in literature on shading method Drumond assembly. This study aims determine effectiveness three methods correction irradiance with bands: LeBaron method, Battles Dal Pai method. Laboratory Solar Radiometry Botucatu provided global, direct,...

Electroencephalography (EEG) is the most common method to access brain information. Techniques monitor and extract signal characteristics in farm animals are not as developed those for humans laboratory animals.

Brain from six Holstein heifers that could freely paddock compartment were acquired. control group consisted same number bovines, contained climatic...

<title>Abstract</title> Knowledge of the rainfall regime is vital information for agricultural and environmental activities. Rainfall a component hydrological cycle, in which liquid water uses energy from environment to change its phase gaseous phase. The cooling this vapor causes condensation subsequent precipitation. Mean precipitation values, distribution during year, variation between years, maximum minimum values are useful parameters rural urban planning. This study aimed characterize...

As radiações solares de ondas longas são complexas na medição devido a conceitos físicos exigentes e custosos equipamentos.
