Characterization and mapping of waste from coffee and eucalyptus production in Brazil for thermochemical conversion of energy via gasification

Abstract: The generation of waste is an intrinsic characteristic of forestry and agricultural production and has become a major concern. Brazil is a great agricultural producer, and in recent years both the planted area and crop production have grown significantly, with a corresponding increase in agricultural waste. In the context of climate change, efficiency and energy security, it is fundamental to develop alternative energies that meet the needs of both the energy supply and sustainable development. Wood chips and coffee husks are low cost residues and potentially capable of generating heat, steam and electric power, thus they can serve as an alternative fuel for generating energy. This work aims to relate the agricultural market to the energy market, using waste from coffee and eucalyptus production to generate energy, as well as mapping waste production in Brazil by region. It was observed that Brazil has a great capacity to generate alternative energy, since approximately 11.4×10 6 t of wastes are generated per year from coffee and eucalyptus production alone. These wastes can be used for the thermochemical conversion of energy via gasification, with potential to generate a total of 201.3 PJ.

Plant functional types and traits as biodiversity indicators for tropical forests: two biogeographically separated case studies including birds, mammals and termites

Abstract: Multi-taxon surveys were conducted in species-rich, lowland palaeotropical and neotropical forested landscapes in Sumatra, Indonesia and Mato Grosso, Brazil. Gradient-directed transects (gradsects) were sampled across a range of forested land use mosaics, using a uniform protocol to simultaneously record vegetation (vascular plant species, plant functional types (PFTs) and vegetation structure), vertebrates (birds, mammals) and invertebrates (termites), in addition to measuring site and soil properties, including carbon stocks. At both sites similar correlations were detected between major components of structure (mean canopy height, woody basal area and litter depth) and the diversities of plant species and PFTs. A plant species to PFT ratio [spp.:PFTs] was the best overall predictor of animal diversity, especially termite species richness in Sumatra. To a notable extent vegetation structure also correlated with animal diversity. These surrogates demonstrate generic links between habitat structural elements, carbon stocks and biodiversity. They may also offer practical low-cost indicators for rapid assessment in tropical forest landscapes.

Issues of the social web interaction project faced with afterlife digital legacy

Abstract: Interacting on the Social Web, people, feelings and properties are connected, generating digital legacy beyond life. Digital life goes further than the bodily one, and software limits make it difficult to model these aspects. Besides, there is a great difference between the criteria for identifying citizens in the real and in the virtual world, including notions of life, death and posthumous data. Interactive systems modeling concerning these issues are discussed, based on bibliographic research, observations of the Web and field research. Therefore, the volitional element is discussed, namely, software planning considering the user's decision on the destination of his digital legacy.

Circuit weight training vs jogging in metabolic risk factors of overweight/obese women.

Abstract: BACKGROUND Resisted and aerobic exercises are recommended to reduce weight and improve health, but which exercise modality offers the best results is still unclear. OBJECTIVE The aims of this study were to compare circuit weight training (CWT) with jogging (JOGG) on multiple cardiovascular disease (CVD), metabolic risk factors and fitness of overweight and obese women (body composition, lipid profile, uric acid, glucose, metabolic equivalent (MET), heart rate, blood pressure, flexibility, resting energy expenditure (REE) and nitrogen balance (NB)). METHODS Fifty women were randomly divided in two groups, but only 26 finished it: CWT (n=14; 36+/-12 years old; body mass index, BMI=32+/-7 kg/m(2)) and JOGG (n=12; 37+/-9; BMI=29+/-2). The first month of training consisted of 60 min x 03 days/week and the second month of training consisted of 04 days/week for both protocols and a dietary reeducation. RESULTS Both groups reduced total body mass, fat body mass, BMI, plasma uric acid and increase in MET (p<0.05); there was no change in lean body mass, REE and resting heart rate. CWT reduced total cholesterol, plasma triglycerides, NB and increased flexibility; JOGG reduced waist/hip ratio, glucose, systolic blood pressure, high-density lipoprotein cholesterol, and increased the total cholesterol/high-density lipoprotein cholesterol ratio (p<0.05). CONCLUSION Both protocols improved CVD and metabolic risk factors. The CWT presented favorable changes regarding lipid profile and flexibility; JOGG on glucose, waist/hip ratio and blood pressure. These results suggest that resisted exercise combined with aerobics should be considered for obese people. Nevertheless, regarding some basal differences between the groups , it was not possible to conclude that changes were due to exercise type or intra-group variability.

A violência contra crianças e adolescentes: características epidemiológicas dos casos notificados aos Conselhos Tutelares e programas de atendimento em município do Sul do Brasil, 2002 e 2006

Abstract: Summary In this study we have built epidemiological features of violence against minors under 15 years of age who live in Londrina, State of Parana, Brazil based on all cases reported to the local Juvenile Courts and Child Protective Services in 2002 and 2006. We have analyzed 607 cases reported in 2002 and 1,013 cases reported in 2006. Violence has mainly occurred in the victim’s own house and for about one or two years prior to the report. Physical abuse was prevalent (52.9% in 2002 and 48.2% in 2006). By comparing the two years of the study, there was an increase in the incidence of all sorts of violence and reoccurrence of violence in 172 cases (10.6%). Although all reports from both years were analyzed, it was a cross-sectional study and its characteristics can be modified when interventions are implemented. The growing incidence from 2002 to 2006 point at the importance of investments, both in prevention and information improvement.
