The amphiphilic particles were added to matrix of HDPE and the modified polymer composites were exposed to ionizing radiation x-rays for different times. For fecal coliforms, about 3 logarithmic units log. We are just displaying deboa. Food safety through the training of 2-alcilciclobutanonas in processed foods by ionizing radiation; Seguranca alimentar atraves da formacao de 2-alcilciclobutanonas em alimentos processados por radiacao ionizante. Pelos resultados obtidos, observou-se que o. In pulp, the doses of gamma radiation of 4. Study of radiation in fresh tomatoes lycopersicon esculentum Mill and in the levels of sauce lycopene; Estudo da radiacao ionizante em tomates in natura lycopersicum esculentum Mill e no teor de licopeno do molho. The passion fruit Passiflora edulis is originary from Tropical America and has been growing largely in Brazil, being a crop very rich in vitamin C, calcium and phosphorus.

It also allows the realization of the reaction at low temperatures. Bacteria of the genera Bacillus and Lactobacillus are the most common contaminants of the ethanolic fermentation and they might cause a decrease in the fermentative yield. Among these post harvest treatments for food conservation it may be stood out the irradiation, which is the focus of this study. The samples of femoral vein were obtained from 56 New Zealand rabbits, male with ageing from 90 to days, that were divided into 4 groups of 14 animals: The efficacy of S. The data in this whois database is provided to you for information purposes only, that is, to assist you in obtaining information about or related to a domain name registration record.

The purpose of the present study was to determine the effects of ionizing radiation in tomatoes Lycopersicon esculentum Mill and at the same time to evaluate the influence of irradiation severiwno the content of lycopene in a sauce made with these fruits irradiated. Stability of phenolic compounds of the propolis processed by ionizing radiation; Estabilidade de compostos fenolicos da propolis processada por radiacao ionizante.

The efficacy of S. After obtaining the films, some assays were realized to evaluate the mechanical properties.

Molecular scission degree was calculated from viscosity measurements which value found is 1 and the crosslinking was not observed at sterilization doses.


Evaluation of X ray attenuation by means of radiographic images; Avaliacao da atenuacao da radiacao X por meio de imagens radiograficas. By the ELISA s test we can find the egg shoppign ovo mucoid and the radiation treatment do not showed considerable changes.

Itepan, Natanael Marcio, E-mail: In the direct effect the radiation interacts with the DNA molecule, breaking it, and then inactivates the cell. The effect of gamma irradiation from a Cobalt source on Callosobruchus maculatus Fabr.

The microbiological analysis pretended to verify the elimination of the pathogenic microorganisms: Metallurgy slag is an interesting source of Si for soils cultivated with this crop. Objective – To point out the impact of gastrectomy on the nutritional status focusing on both mechanical and chemical. A Raman spectrometry was used to identify the polymorph of titanium oxide, rutile.

The variation on the concentration of the tetracycline-benzyl alcohol solution caused by several doses of gamma radiation was determined by using the spectrophotometric technique. O sistema pode produzir entre 94 e vezes mais energia do que consome. Impurity-related point defects and gamma-radiation response of massive quartz from the Borborema pegmatite province, in Brazil; Estudo da suscetibilidade ao escurecimento por radiacao gama de quartzo roseo-leitoso da provincia pegmatitica da Borborema.

The radiation processing resulting in characteristic patterns formations of saturated hydrocarbons, aldehydes, methyl and ethyl esters and 2-alcilciclobutanonas, depending on the fatty acid composition of the lipid that composes the food. It can be observed that the sample of control collard greens showed high antioxidant activity and for the samples treated by irradiation was a decrease of percentage.

Brazilian savannah is the second biome of American Continent and concentrate a lot of plants and animal species. These problems are due to factors such as small scale production, lack of standardization of products and processes, deficiencies in effective control of quality, difficult to define niche markets and different levels of technology.

It was further verified that the number of eggs laid decreased with the irradiation dose. A pesquisa foi caracterizada como um estudo de caso descritivo.

Just now, they are gained attention of researchers due their nutritional properties, between then is the pequi fruits. In the property of resistance to the glow wire the polyamide 6 with fibreglass reinforcement had a good performance.


Kinoplex completes digital cinema roll-out | Christie – Audio Visual Solutions

Natural radiation; A radiacao natural. Through of the results observed that with the increase of the dose of radiation, decreased the total microbial count and that the irradiation retarded the ripening according to increase of the dose, this probability of the destruction of bacterial lactic.

Faculdade de Ciencias Quimicas]. The geometry chosen for the simulations is a circle with a non homogeneous circular form in its interior. It was concluded that gamma radiation has excellent potential for the synthesis of hiperabsorbent hydrogels. Ingestion of natural radionuclides with local food is only of minor radiological consequence.

Assim, o goiahia foi desenvolver um produto, a partir de cascas de banana, chuchu e talos de couve. With the methodology utilized we observe changes in the femoral vein of the animals submitted to irradiation in relation to the control group, thus described: These results corroborate for the understanding that there would be no need of addition of enzymatic improvers for the bread confection.

These materials find use in several application fields, such as sanitary pads, diapers, sevveriano release of nutrients to the soil, separation processes, water purification systems and controlled release of drugs. The sensory analysis showed no significant difference between different times of cooking analyzed.

Between them it is used polyamide 6 that it presents good tension resistance, to the impact and the humidity absorption compared with non-reinforced, being also at the present time used in the automobile industry in parts underneath the hood, especially in the radiator frames.

With a defined concentration of PVP and PVAL, films of this blend was irradiated and also solutions with different concentrations of chitosan was prepared to obtain new films of this blend.
