1. Shelf-life of loricariid catfish (Pterygoplichthys disjunctivus [Weber, 1991]) roe stored in ice
Abstract Loricariid catfish (Pterygoplichthys disjunctivus [Weber, 1991]) has invaded water catchments throughout the world, due to the lack of predators and high fecundity. An approach to control its population could be using its roe as food; however, more knowledge is needed. Thus, the present study aimed to evaluate the shelf-life of fresh loricariid catf

2. Action of two endocrine disrupters on the sexual differenciation of Nile tilapia
RESUMO Desreguladores endócrinos são substâncias exógenas que possuem a capacidade de alterar uma ou várias funções do sistema endócrino com efeitos adversos a saúde um organismo intacto. O objetivo principal do presente trabalho foi avaliar a ação dos desreguladores endócrinos 17β-estradiol (E2) e 17α-etinilestradiol (EE2) na diferenciação s

3. Numerical Simulation for the Collision Between Side Structure and Level Ice in Event of Side Impact Scenario
Abstract With the opening of the Northern Sea for international shipping routes, various vessels prefer to use this option to reach Europe as distance is significantly reduced if a ship is sailing through this route. In the same time, the demand to ensure ship safety rises as impact phenomenon between ship structures and ice causes numerous casualties. This

4. Physicochemical properties of frozen tortillas from nixtamalized maize flours enriched with β-glucans
AbstractEffects of different β-glucan concentrations in maize flour on the properties of frozen maize tortillas were evaluated. Masa (dough), pre-cooked (PTs), frozen (FTs), thawed (TTs), and cooked tortillas (CTs) were made and analyzed. Moisture content of masa and tortillas significantly decreased as β-glucan concentration increased; however, the water

5. Ocorrência e avaliação do potencial enterotoxigênico de Staphylococcus isolados de derivados lácteos / Ocurrence and assessment of enterotoxigenic potencia of Staphylococcus isolated from dairy products
Staphylococcus are microorganisms widespread in nature and humans and animals are their main sources. Cross-contamination after milk pasteurization, caused especially by improper handling, is considered the most recurrent source of dairy products contamination by these pathogens. Staphylococus deserves our close attention due their ability to produce a large

6. Atividade antioxidante de gabiroba e aplicação da polpa como ingrediente em sorvete
The aim of this study was to verify the antioxidant properties of gabiroba fruits, with potential use as an ingredient in dairy products. The gabiroba (Campomanesiaxanthocarpa O. Berg) belongs to the Myrtaceae family and it is found in west-central, southeastern and southern Brazil. It was evaluated the antioxidant activity of gabiroba pulp (P1) and the whol

7. A Concentração de sódio no testemunho de gelo da Ilha James Ross como indicador da variabilidade da extensão do gelo marinho
This dissertation investigates the relationship between the sodium concentration in an ice core (D98) from James Ross Island (Antarctica) and the area covered by sea ice in the Bellingshausen and Amundsen Seas during the 1979¿1991 period. The D98 total sodium content derives from samples analyzed by Joseph McConnell (McConnell et al., 2007). Sea ice coverag

8. SIMULTANEOUS DETERMINATION OF ORGANIC COMPOUND RESIDUES IN WATER SAMPLES BY DISPERSIVE LIQUIDLIQUID MICROEXTRACTION (DLLME) AND GC-(TQ)MS/MS / DETERMINAÇÃO DE RESÍDUOS DE COMPOSTOS ORGÂNICOS EM ÁGUA POR MICROEXTRAÇÃO LÍQUIDO-LÍQUIDO DISPERSIVA (DLLME) E GC-(TQ)MS/MS
The use of chemicals, which generates a lot off benefits, is responsible for the contamination of soil, water and foods. The concern about contamination of surface and ground water systems by pesticides has grown in scientific circles, especially by the presence of pesticides and other compounds in water sources. Thus, rapid analytical methods, sensitive and

9. Viabilidade técnica de uma rota não convencional para a produção de leite de cabra em pó em cooperativas do Rio Grande do Norte
Nowadays, Brazil has both the greatest goat herd and the greatest goat milk production of South America. The state of Rio Grande do Norte, located in northeast of Brazil, has an average year production of three thousand cubic meters of goat milk in natura. Part of this milk production is homemade and it comes from small farms, which unite in rural cooperativ

10. Relation between the Antarctic Sea ice concentration and low temperatures in South America / Relação entre a concentração de gelo marinho Antártico e a temperatura mínima na América do Sul
The Antarctic Sea Ice Concentration (ASIC) is thought to be an important element in the analysis of the world climate. However, few studies have investigated its relation to other climatic elements. Thus, the aim of this study was to verify the relation between the ASIC and low temperatures in South America through two approaches. The first, regional, invest

11. Simulação numérica da separação de misturas CH4/He e CO2/He em colunas de adsorção em leito fixo
Methane and carbon dioxide gases are part of natural gas composition and methane is in bigger proportion. Both gases are pollutants which methane is the most responsible by the greenhouse effect and carbon dioxide in turn by pipelines oxidation in natural gas transporting. The separation of CO2 from natural gas promotes an increase in calorific power of the

12. PHYSICAL, CHEMICAL AND ACCEPTABILITY OF ICE CREAM WITH mangaba and REDUCED ENERGY CONTENT / CARACTERÍSTICAS FÍSICAS, QUÍMICAS E ACEITABILIDADE DE SORVETE COM MANGABA E REDUZIDO TEOR ENERGÉTICO
Mangaba (Hancornia speciosa Gomez) is a typical Cerrado biome fruit widely used in regional gastronomy and pharmacology. Its distinguished potentialities brought up increased interest and stimulated sustainable cultivation in the Northeast and Central West Regions of Brazil. The replacement of shortening and sugar on the physical and chemical properties of m
