| This paper presents a method to estimate the biomass of Spirulina cultivated on solid medium with sugarcane bagasse as a support, in view of the difficulty in determining biomass concentrations in bioprocesses, particularly those conducted in semi-solid or solid media. The genus Spirulina of the family Oscillatoriaceae comprises the group of multicellular filamentous cyanobacteria (blue-green microalgae). Spirulina is used as fish feed in aquaculture, as a food supplement, a source of vitamins, pigments, antioxidants and fatty acids. Therefore, its growth parameters are extremely important in studies of the development and optimization of bioprocesses. For studies of biomass growth, Spirulina platensis was cultured on solid medium using sugarcane bagasse... |

| The reduviid predators Rhynocoris marginatus (Fab.) and Catamirus brevipennis (Servile) use their venoms to paralyze their preys. We detected the antibacterial activity of R. marginatus and C. brevipennis venoms against seven Gram-negative and four Gram-positive bacteria by using the disc diffusion method. Rhynocoris marginatus venom exhibited antibacterial activity against four Gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa, Proteus vulgaris, Salmonella typhimurium) and one Gram-positive (Streptococcus pyogenes). Catamirus brevipennis venom showed antibacterial activity against six Gram-negative (Escherichia coli, Proteus mirabilis, Pseudomonas aeruginosa, Klebsiella pneumoniae, Proteus vulgaris, and Salmonella typhimurium) and three... |

| Abstract The antioxidant effects of tea catechins (TC) on the shelf life of raw minced duck meat were investigated by measuring the levels of lipid peroxidation, globulin precipitation, and TC residues during refrigeration (4 °C). TC was added to the raw minced duck meat at 0 (T0), 300 (T300), 500 (T500), 800 (T800), or 1000 (T1000) mg/kg. Treated samples were stored in a refrigerated (4 °C) display cabinet under aerobic conditions for 10 d. The levels of lipid peroxidation (thiobarbituric acid reactive substances), globulin precipitation, and TC residues were measured every 2 d. TC-treated duck meat displayed significantly lower (P < 0.05) lipid peroxidation compared with the control under refrigerated aerobic conditions, indicating that the TCs have... |

| O girassol e uma planta originaria das Americas, que foi utilizada como alimento, pelos indios americanos em mistura com outro vegetais. No seculo XVI, o girassol foi levado para a Europa e Asia, onde era utilizada como uma planta ornamental e como hortalica. Foram na Uniao Sovietica os primeiros trabalhos de melhoramento genetico visando a producao de genotipos com altos teores de oleo comestivel. Atualmente, o girassol ocupa o quarto lugar como fonte de oleo, em relacao a soja, palma e canola. Como fonte proteica, o girassol tambem e classificado como a quarta opcao, para racao animal e uso humano. Os derivados proteicosde girassol, que podem ser utilizados como ingrediente alimentar, incluem a farinha, o concentrado e o isolado proteico. O conteudo de... |

| ABSTRACT VC (20%), TC (20%) and N:P:K fertilizer (farmer's practice) were used to determine the growth and yield attributes of bush bean (Phaseolus vulgaris), winged bean (Psophocarpus tetragonolobus) and yard long bean (Vigna unguiculata). Plants grown with VC (20%) produced the highest fresh biomass for bush bean (527.55 g m-2), winged bean (1168.61 g m-2) and yard long bean (409.84 g m-2). In all the tested legumes the highest pod weight, pod number, pod dry weight and pod length were found in the VC (20%) treatment. Photosynthetic rates in the three legumes peaked at pod formation stage in all treatments, with the highest photosynthetic rate observed in winged bean (56.17 µmol m-2s-1) grown with VC (20%). The highest yield for bush bean (2.98 ton... |

| Winter rapeseed (Brassica napus L.) has potential to become an alternate oilseed crop both for edible oil production and energy agriculture (biofuel production) for Turkey. This study was conducted to determine the effect of year, N sources and doses on the yield and quality traits of winter rapeseed in a cereal system in calcareous soils over two seasons, 2000-2001 and 2001-2002, in Central Anatolia. Three N sources, ammonium sulfate, ammonium nitrate and urea, were applied as hand broadcast on the soil surface at five doses (0, 50, 100, 150, and 200 kg N ha-1). The traits investigated were plant height, number of branches and pods per plant, number of seed per pod, thousand seed weight, seed yield, oil and protein content. There were significantly... |

| This paper analyzes the summer and winter total protein content of 7, 14, 21, 28, 35, and 40-day old Apis mellifera L. worker venom glands before (control) and 24 and 96 hours after applying electrical shocks for venom extraction (experimental). During venom extraction, 7-day old workers responded more slowly and weakly to electrical shocks. This response intensifies with age, so that the workers approaching 20 days old respond faster and more aggressively to the shocks. Statistical analysis, using the non-parametric Wilcoxon and Kruskall-Wallis tests and complemented by the Jonckheere test, showed that the protein content varied from one age to another in the experimental group, which was well distinguishable from the values in the control Group in summer... |

| O presente trabalho foi com o objetivo de estudar a variação do crescimento médio diário e do valor nutritivo do capim-gordura, durante a estação de pastejo. Utilizou-se um delineamento em parcelas subdivididas e um arranjo fatorial 2 x 3 x 4 x 3 para estudar dois períodos de descanso (28 e 42 dias), três épocas de crescimento (I: Nov - Jan; II: dez-fev e III: jan-abr), quatro idades (21,35,49 e 63 dias) e três repetições. O campi-gordura apresentou um crescimento aproximadamente linear, independentemente do período de descanso e da sucessão dos crescimentos. O período de descanso de 2 dias resultou em menor rendimento forrageiro, verificando-se todavia, interação período de descanso x crescimento. Para os períodos de descanso de 28 e 42 dias, os... |
