3. First evaluation of semidirect recycling methods for the reclamation of cemented carbides based on a literature survey
ABSTRACT At the moment the industrially applied techniques for cemented carbide reclamation feature several deficiencies. Depending on the process route, obstacles consist in high energy and chemical consumption (indirect recycling methods) or a deterioration of the recycled product in comparison with the primary material (direct recycling approach). Therefo

4. Releasing systems for aerospace industry based upon Shape Memory Alloys: characterization of materials for actuators
ABSTRACT Releasing and deployment maneuvers carried out during space satellites launching are usually performed by utilizing pyrotechnics loads. However, it is considered convenient to replace this technique by others not requiring explosives (Non Explosive Actuators-NEA). This is mainly due to the necessity of reducing high-shock and vibrations induced leve

5. TECHNOLOGICAL QUALITY OF SOYBEAN OIL OBTAINED FROM STORED GRAIN UNDER CONTROLLED ENVIRONMENTAL CONDITIONS
ABSTRACT: Soybean oil has many important components, but for its maintenance it is essential that there is an appropriate storage, temperature, relative humidity and optimum grain moisture content, because the oxidation reactions occur by improper storage, causing product deterioration. The objective of this study was to evaluate the main changes in the qual

6. Selective serotonin reuptake inhibitors for fibromyalgia syndrome
ABSTRACT BACKGROUND: Fibromyalgia is a clinically well-defined chronic condition with a biopsychosocial aetiology. Fibromyalgia is characterized by chronic widespread musculoskeletal pain, sleep problems, cognitive dysfunction, and fatigue. Patients often report high disability levels and poor quality of life. Since there is no specific treatment that alte

7. Forced-air, vacuum, and hydro precooling of cauliflower (Brassica oleracea L. var. botrytis cv. Freemont): Part II. Determination of quality parameters during storage
Cauliflower heads, which were precooled using four different methods including vacuum, forced-air, and high and low flow hydro precooling, were stored under controlled atmosphere and room conditions. Controlled atmosphere conditions (CA) were as follows: 1°C temperature, 90 ± 5% relative humidity, and 0:21 [(%CO2:%O2) – (0:21) control] atmosphere composi

8. Qualidade de sementes de soja convencional e transgÃnica apÃs colheita e durante armazenamento em condiÃÃo ambiente e em resfriamento / Seed quality of conventional and transgenic soybean after harvest and storage in warehouse and cooling conditions
In a scenario where there is increasing production of soybeans, the quality of the storaging process is a factor of increasing concern, which requires the incorporation of technologies and production systems research in seed companies, adopting measures to ensure the viability of the seed during storage. This study aimed to evaluate the quality of seeds of f

9. Condições de armazenamento e conservação do potencial fisiológico de sementes de diferentes genótipos de milho / Storage conditions and seed performance of different corn genotypes
Seed storability is affected by several factors including genotype and environmental conditions. Corn seed producers are highly concerned with variations in seed longevity of different hybrids, resulting in lower performance than desired during the normal sowing season as much as during off season times. The objective of this research was to evaluate the eff

10. Cellular aging: theories and technological influence
The aim of this article was to review the factors that influence the aging, relationship of aging with the biological rhythms and new technologies as well as the main theories to explain the aging, and to analysis the causes of aging. The theories to explain the aging could be put into two groups: those based on a program that controlled the regression of th
