Controle de crescimento e redução de biofilmes pela aplicação de potencial ou corrente elétricos em superfícies metálicas, condutoras ou semicondutoras

Descrito como o presente Privilégio de Invenção, refere-se a um processo para a desinfecção de superfícies condutoras ou semicondutoras, evitando a formação ou eliminando biofilmes preexistentes, para tanto, o presente processo é realizado por meio da aplicação de um potencial ou corrente elétricos sobre as referidas superfícies sendo vantajosa por dispensar o uso de agentes biocidas, bem como não necessitar do uso de materiais ou produtos abrasivos, ou seja, com a tecnologia proposta no presente processo é possível controlar ou eliminar a presença de biofilmes em sistema industriais sem adição de substâncias ao sistema, pois no presente processo o reagente é o elétron ou o campo elétrico formado por ele.

Avaliação preliminar dos efeitos de Coffea arabica sobre a obesidade induzida por dieta hipercalórica

Obesity along with overweight, has been considered one of the most serious public health problems in the world, especially because they are the main risk factors for many chronic diseases, such as coronary heart disease, type II diabetes mellitus, hypertension and some types of tumors, which are associated with high mortality rates. The use of functional foods and appropriate diets to call health promotion has grown as a mechanism for prevention, control and treatment of chronic diseases such as obesity. Several ethnopharmacological studies indicate plant species for the treatment of disorders associated with obesity with a major attraction of this regimen is perceived as safer and more effective health than the traditional treatment with appetite suppressants. This work aims to develop and standardize models of biological assays in stress and obesity, also aims to evaluate the effect of oil green beans of Coffea arabica in the regulation of body weight and energy balance in mice. To this end, trials were made in vivo studies of this product and their effects on energy metabolism in non-obese mice with obesity induced by hypercaloric diet. After induction of obesity by 8 weeks, animals were treated for 21 days with the extracts orally. After 21 days the animals were killed to evaluate the effects of these products on daily feed intake and on body weight. The group treated with the oil of Coffea arabica L. showed significant weight loss and feed intake high. According to the results, we conclude that the standardized extract of Coffea arabica L. decreased body weight without restriction or decrease the amount of food ingested

Avaliação dos efeitos do cogumelo do sol (Agaricus blazei) sobre o colesterol plasmático em coelhos com hipercolesterolemia induzida

Prophylactic or therapeutic treatments administered with medicinal plants and natural products are used in popular medicine of diverse people since prehistoric times to the present days. Species with medicinal properties are increasingly studied in an attempt to understand their possible effects on organisms and their functioning. This study aimed to analyze the effect of the mushroom Agaricus blazei (aqueous extract) in rabbits subjected to experimental hypercholesterolemia. The animals were divided into two groups (control and treated with the mushroom) whose experimental protocol was divided into three phases: Phase 1, the animals were fed a normal diet to evaluate the physiological level of cholesterol; phase 2, the animals were fed a supplemented diet to induce hypercholesterolemia and in phase 3, the animals of control group continued to take high-cholesterol diet and the animals of treated group high-cholesterol diet including treatment with the mushroom. Weekly, after fasting of 14 hours, blood samples were collected from the animals and its plasma was stored for later measurement of plasmatic cholesterol. In the first phase, the cholesterol level was, on average, 31,30  7,34 mgdL-1. In the second phase, there was a significant increase (p<0,05) in cholesterol level of both groups. During the last phase of the experiment, the mushrooms didn’t cause reduction in plasmatic cholesterol of treated rabbits, however, prevent disease progression, maintaining the cholesterol level established at the beginning of treatment, whereas, in the control group, total serum cholesterol increased significantly at this stage

Estudo sobre fornos de tratamento térmico e propostas de cogeração de energia em usina siderurgica não integrada

Steel industry is a sector heavily dependent on energy, both electrical and thermal. Since the receipt of raw materials to the shipment of finished products to customers, through mergers, casting, rolling, heat treatment, inspection, among others, high amounts of energy are demanded, generating very significant costs to the productive chain in its entirety . Therefore, any alternative that favors the reduction in energy consumption or barateie the cost of this is very welcome. Within this context, this paper aims to make a technical and economic analysis of installing a cogeneration plant in the field rolling in a non-integrated steel mill. Two configurations are proposed plants, with one being the use of heat from waste gases from furnaces existing in the area mentioned and another with the use of heat from waste gases from an internal combustion engine. Both proposals are evaluated technically and later is done the economic analysis, calculating the financial return (pay back) in relation to the investment required, operation and maintenance of the plant

Inovação tecnológica em projetos de novos produtos: um estudo exploratório sobre relações gerenciais de integração entre unidades de uma multinacional

Although thetopic of integrationin product development is widely debated in the literature, there are few studies that address the participation by subsidiaries of multinational and R & D centers around the world in development projects of new products. Focusing on the perception of the Brazilian unit, this paper aims to present and analyze integration practices among subsidiaries, headquarters and R&D centers in product development projects in amultinational high tech company. For this purpose, was conducted an exploratory and qualitative researched operationalized by case study. Among the main results, it was noted collaboration betweenlocals marketing and engineering with the R & D centers, important role of senior management in the Brazilian unit to communicate outcomes of the strategic planning of products andtechnologies established by the headquarters to the subsidiary, the adoption of technological and information mechanisms and the application of methods such as technology roadmap.
