We investigated the effects of formulations based on phosphite products on gas exchange and activity of antioxidant enzymes in coffee plants. Seedlings of the Mundo Novo cultivar were submitted to various treatments composed of different formulations of with potassium phosphite (ADB 120), manganese phosphite (Reforce Mn), and fungicide (PrioriXtra®). For coffee seedlings, the combination of potassium phosphite and citrus by-products, isolated or in a combination with other products elicited the antioxidant system. Besides the high activity of antioxidant enzymes, the photosynthetic rates were higher than other treatments. The better performance of coffee seedlings treated with those formulations occurred even in absence of pathogens.

Abstract: As a es humanas têm alterado a biosfera. O aumento de gases de efeito estufa (GEE) na atmosfera está fazendo a temperatura no planeta subir. O aquecimento global implicará mudan as climáticas, ecológicas, econ micas e sociais. Os Mecanismos de Desenvolvimento Limpo (MDL) permitem que os países industrializados financiem projetos de redu o de emiss es de GEE em países em desenvolvimento. O objetivo deste trabalho foi demonstrar que o biogás usado como fonte energética na Cadeia Produtiva de Frango de Corte é um projeto elegível no ambito do MDL. A receita obtida da comercializa o dos Certificados de Emiss es Reduzidas pode ser usada no financiamento da planta de gera o de energia. Human activity has changed the biosphere. The increase of greenhouse gases (GHG) emissions in the atmosphere is causing the temperature rise on the planet. Global warming will lead climate, ecological, economic and social changes. Clean Development Mechanism (CDM) allows industrialized countries to finance projects for reducing GHG emissions in developing countries. This study aims to demonstrate that the use of biogas as an energy source in the Production Chain of poultry is an eligible project under the CDM criteria. The proceeds of the sale of Certified Emission Reductions can be used to finance the power generation plant.

Abstract: The experiment aimed to evaluate the effect of phytase enzyme in rations for swine at the finishing phase without the use of mineral-vitamin supplement and with reduced levels of inorganic phosphorus on performance and carcass characteristics, ashes and mineral percentage in the bones and economic viability. Twenty-four hybrid females with starter weight of 66 ± 1.4 kg and final weight of 106 ± 1.8 kg were housed for 38 days in 24 stalls and allotted in a completely randomized experimental design with six treatments and four replications of two animals each. The following treatments were used: T1 –basalfeed; T2 – basal feed without micromineral-vitamin supplement; T3 – basal feed with phytase and without micromineral-vitamin supplement; T4 – basalfeed with phytase, without micromineral-vitamin supplement and without 1/3 of inorganic phosphorus; T5 – basal feed with phytase, without micromineral-vitamin supplement ans without 2/3 of inorganic phosphorus; and T6 – basal feed with phytase, without micromineral vitamin supplement and without inorganic phosphorus supplementation. The withdrawal of the micromineral-vitamin supplemet, the reduction of inorganic phosphorus level and the addition of phytase enzyme did not affect (P>0.05) the carcass characteristics, but they reduced (P<0.05) feed intake and weight gain, and showed worse feed conversion. Likewise, reduction of inorganic phosphorus levels and phytase addition did not improve economic efficiency when compared to basal feed.

Mathematics , 2015, DOI: 10.12785/amis/oliveira
Abstract: Iterations of odd piecewise continuous maps with two discontinuities, i.e., symmetric discontinuous bimodal maps, are studied. Symbolic dynamics is introduced. The tools of kneading theory are used to study the homology of the discrete dynamical systems generated by the iterations of that type of maps. When there is a Markov matrix, the spectral radius of this matrix is the inverse of the least root of the kneading determinant.

Abstract: improvement of agricultural management through the increased knowledge on production activities has been discussed as decision-making strategies. real-time field level positioning may allow site-specific investigation of soil and plant variables. in brazil, the grain crops show great need for research in this area, due to their importance and technological demand. aimed at discussing some aspects of the increased level of information on an agricultural environment, a field experiment was installed in 1998 in angatuba, sp, on a grain crop. in an area of 34,3 ha, irrigated by a center-pivot system, monitoring of maize yield was done in the growing season 99/00 besides the soil fertility parameter. results showed different patterns of yield distribution inside the field, and the causes of observed yield variability. preliminary analysis of soil data showed low correlation between yield and soil chemical properties in a site-specific base. observation of yield data suggests the development of strategic management zones, based on trend analysis of the most influent yield components.

Abstract: malnutrition hampers the course of schistosomiasis mansoni infection just as normal growth of adult worms. a comparative morphometric study on adult specimens (male and female) recovered from undernourished (fed with a low protein diet - regional basic diet) and nourished (rodent commercial laboratory food, nuvilab) white mice was performed. tomographic images and morphometric analysis of the oral and ventral suckers, reproductive system and tegument were obtained by means of confocal laser scanning microscopy. undernourished male specimens presented smaller morphometric values (length and width) of the reproductive system (first, third and last testicular lobes) and thickness of the tegument than controls. besides that, it was demonstrated that the dorsal surface of the male worms bears large tubercles unevenly distributed, but kept grouped and flat. at the subtegumental region, vacuolated areas were detected. it was concluded that the inadequate nutritional status of the vertebrate host has a negative influence mainly in the reproductive system and topographical somatic development of male adult schistosoma mansoni, inducing some alterations on the structure of the parasite.
