Acute appendicitis is rare in the postoperative period of liver transplantation;only 23 cases were described in the literature to date, including late and immediate postoperative. Our case reports a patient who was presented with acute appendicitis in the immediate post-transplant and died in the subsequent postoperative period. The article reviews the available literature and all cases known until now, commenting on incidence, casual factors, symptoms, diagnostic and management.

Simple statistical models were developed to relate available meteorological data with daily river discharge （RD） for rivers not influenced by melting of ice and snow. In a case study of the Vouga River （Portugal）, the RD could be determined by a linear combination of the recent （PR） and non-recent （PNR） atmospheric precipitation history. It was found that a simple linear model including only PR and PnR cannot account for low RD. The model was improved by including non-linear terms of precipitation that accounted for the water loss. Additional improvement of the models was possible by including average monthly air temperature （7）. The best model was robust when up to 60% of the original data were randomly removed. The advantage is the simplicity of the models, which take into account only PR, PNR and T. These models can provide a useful tool for RD estimation from current meteorological data.

While the main concerns with municipal solid waste in developed countries like the European Union and the United States are to reduce and recycle the energy recover in order to drastically reduce the residues disposal to landfill, for developing countries the targets on waste management are much more basic. This seems to be the case in Brazil that with a new regulation, it still attempts to eradicate the inadequate waste disposal for open dumps. Thus, the aim of this paper is to depict the context, the criteria and discuss the strategies used for: the municipalities achieve the goals and adhere the plan;choice and configuration of disposal sites;and economic instruments adopted and bringing the whole scenario to discussion, including methane emissions inventory thru the case study of the Rio de Janeiro State. The Rio de Janeiro State municipal solid waste management scenario has drastically changed in last five years from 9% of residues sent to adequate destinations, to the perspective of eradication of open dumps before the end of 2014. The results indicate that only adequate disposal of waste is mandatory with the prevalence of the sanitation approach. The evidences also indicate that planning goals to reduce waste are modest and the landfill gas recover is generally accepted as the optimal solution. This paper concludes that, unless the stakeholders add to the plan a more aggressive policy to increment, the competitiveness of other waste technologies that favor the landfilling reduction and energy recover, Rio de Janeiro State will face the increase of landfill numbers and sizes, management cost, environmental and leachate impact, post-closure care expenses, contaminating life-span, and methane emissions.

Livestock is the most important economic activity in San Vicente del Caguán municipality, Caquetá department (located in Colombian Amazon region). Indeed, livestock activities have a big responsibility of Colombian Amazon forest deforestation for extensive grazing lands formation, causing soil degradation processes. However, recently some cattle ranchers have changed their thoughts to a sustainable production, applying different ecological strategies. So, application of silvopastoral systems, which is a very important mode of agroforestry, consists that in the same area and time, it can interact in the ecosystem stratums different species among grasses, shrubs, and trees. On this way, the objective of this study is to determine descriptively the arboreal/arbustive component associated to livestock systems, represented according to its uses in San Vicente del Caguán, Colombia. It was made through a direct survey to 13 smallholders in this municipality. As a result, mainly, we found 58 plant species (49 arboreal and nine arbustive, corresponding to 84.48% and 15.52%, respectively). Of these, 20 species had more than one use at a time. In fact, the shade was the use most common with 29 species, corresponding to 34.94% of total species (25 arboreal and just four arbustive, corresponding to 30.12% and 4.82%, respectively). On this way, according to smallholders surveyed, we can conclude that shade provided by trees integration in silvopastoral systems is for diminishing heat stress on cattle caused by enduring climate change of tropical, thus contributing to good welfare for animals.

The leaf powders from two varieties of Stevia rebaudiana (Bertoni) cultivated in Yucatan, Mexico were analyzed for their proximate composition, dietary fiber composition and functional properties. The leaf powders were a good source of carbohydrates (64.06%-67.98%), protein (12.11%-15.05%), and crudefiber (5.92%-9.52%). Total dietary fiber content in the S. rebaudiana leaf powders were 28.61 (Morita II) and 29.12 (Criolla) g/100g sample, with most of this content represented by insoluble dietary fiber 87.79% (Morita II) and 70.02% (Criolla). Neutral detergent fiber (NDF), acid detergent fiber (ADF) and acid detergent lignin (ADL) were higher in Criolla (19.29%, 17.77%, 8.98%) than Morita II variety (18.11%, 14.16%, 2.28%). Hemicellulose and cellulose were higher in Morita II (3.96%, 11.78%) than criolla variety (1.51%, 8.79%). Functional properties of leaf powder from Morita II and Criolla were, water-holding capacity (2.87-4.07 g/g sample), oil-holding capacity (6.49-6.79 g/g sample), water-absorption capacity (3.41-3.44 g/g sample), water-adsorption capacity (0.25-0.28 g/g sample), and organic molecule absorption capacity (1.13-1.81 g/g sample). These suggest that S. rebaudiana (Bertoni) leaf powders may be used as dietary supplement or as food additive.

Microalgae are unicellular organisms capable of photosynthesis, turning sunlight and carbon dioxide (CO2) into rich biomass. Precisely because of this definition, in recent years various sectors have been targeting their ability to reduce CO2 emissions and the capacity of simultaneously synthesize biomass which can be later used to produce bio-fuels. Besides being considered fast-growth microorganisms, microalgae have a diverse biochemical composition with similar characteristics to traditional biomass. In this context, the present work aimed to evaluate the biofixation of CO2 by the microalgae Monoraphidium sp., cultivated in a closed-window type photobioreactor, as well as characterization of microalgal biomass produced in relation to the total lipid content (TL), lipids converted into biodiesel (LCB), carbohydrates and proteins. The results achieved showed that the best result was obtained after 24 h of cultivation, where for each gram of biomass produced approximately 1.2 g of CO2 were consumed. In the growth phase the average biomass productivity in the Janela photobioreactor was 58 mg·L-1·day-1 concluding that microalgae culture systems could be coupled to the chimneys of large industries emitters CO2 using this gas, resulting from combustion processes, in the process of photosynthesis. The biomass Monoraphidium sp. produced had a content of lipids converted into biodiesel of approximately 8.36% ± 2.69%, carbohydrates 32% ± 3.37% and proteins 34.26% ± 0.41%.
