Due to Brazil is a tropical country has activities in occupational exposure to cold restricted to few sectors especially the meatpacking industry. Taking into account that the country in 2010, was again the largest exporter of poultry meat in the world and consequently employing a large number of workers for their slaughter and processing. The search for greater productivity can result in an in...

Abstract Given the longevity of investments in energy-consuming products (such as household appliances, vehicles, and properties), underinvestment energy efficiency can have long-lasting negative economic environmental consequences. Previous research has indicated that may be due to imperfect information relation long-term benefits investing efficiency. This paper presents results a cluster ran...

This paper presents the development of a sustainable and affordable domestic refrigerator for rural areas where grid setting is weak or non-existent. The uses miniature refrigeration unit based on micro direct current (DC) compressor, which can adjust its speed according to photovoltaic output variation with solar radiation intensity, in order maximize cooling production. experimental investiga...

The purpose of the study was to characterize irrigated smallholder agricultural enterprises (ISAEs) in selected areas Vhembe District, Limpopo Province. characterization focused on geophysical environment and participants ISAEs. Precipitation at most 460mmpa for villages along Madimbo Corridor 701-1380mmpa those Mutale Valley, temperatures were 38.1℃-44.0℃ (Madimbo) 30.0℃-40.0℃ (Mutale). Ground...

Antioxidants are used in a wide variety of food products, and their activity may vary depending on the temperature, food composition, food structure and availability of oxygen. Temperatures at which antioxidant activity may be required range from 180–200°C for frying oils, to about 5 °C for products such as margarine or mayonnaise that are stored in the fridge. Besides the processing and storag...

Foodborne illness is a global public health issue, with food handling in the home identified as an underestimated source. In Australia, there has been a significant increase in the incidence of salmonellosis with the majority of outbreaks linked to eggs. This study investigated Australian eggs consumer attitudes, behaviours and risk perceptions associated with the handling of raw eggs in the ho...

The future is said to belong to information appliances, specialized and easy to use devices that will have the car tell the coffee pot to brew a cup of coffee just in time for our arrival home. These gadgets are supposed to eliminate the complexity and resulting frustrations of the PC. The thesis of this essay is that while information appliances will proliferate, they will not lessen the perce...

A fast and simple method of chiral capillary electrophoresis (CE) has been applied to the analysis of salbutamol in different pharmaceutical preparations. Using of a 25 mM acetate buffer (pH 5.0), containing 13.1 mg/mL carboxymethyl-beta-cyclodextrin (CM-beta-CD), an applied voltage of 20 kV and a temperature of 25 degrees C, the enantiomers of salbutamol could be separated in about 2 min. Thre...

In this research we are concerned with the automatic evolution of programs for control applications, the particular example we use being software for a simple fridge device with two inputs and three outputs. By careful choice of the target programming language in a similar vein to a RISC processor we are able to represent programs as variable length strings and use evolutionary computing techni...
