The study took place in a sewage treatment plant located at the actual Department of Water and Sewer in Bauru, city of Sao Paulo state. This treatment plant has an average entrance flow of 4.8 l. s-1 made by upflow anaerobic filter, followed by wetland systems constructed in parallel. . As objective of this study we evaluate the effectiveness of three systems of constructed wetlands, with three different types of plants (Lily pond, Giant papyrus and Cattail),quantify, and qualify the effluents at various stages of treatment to monitor their effectiveness and the possibility of reuse in agriculture. There was a satisfactory removal of organic matter, with a mean concentration of 36 and 39mg.l-1 at the , phases 1 and 2 of the operation, respectively. The constructed wetlands effluent nitrogen and phosphate concentrations were high throughout all the system and the removal efficiency of ammonia nitrogen was much lower than expected, then the system is functioning as secondary treatment and not as tertiary treatment. The concentrations of micro-organisms found in the final effluent were also high. Therefore, it is concluded that the results of removal efficiency of organic matter, of constructed wetland systems, meet the parameters required by legislation for effluent discharges but do not attend the parameters required for nitrogen and micro organisms. This way, these analyzed plants effluents are suitable for reuse in agriculture restricted irrigation

This paper presents a technique to add flexibility in the control of power electronic converters. The power converter can function as an active power filter, as a local power source interface or perform both functions i. e. mitigate current disturbances and inject power into the grid simultaneously, configuring it as a multifunctional device. The main goal is to extract the full capability of the grid connected power electronic converter to achieve maximum benefits. To achieve this goal, the orthogonal current decomposition of the Conservative Power Theory is used. Each orthogonal current component is weighted by means of different compensation factors (k_i), which are set instantaneously and independently, in any percentage by means of the load performance factors (λ_i), providing an online flexibility in relation to compensation objectives. Finally, to validate the effectiveness and performance the proposed approach, simulations and experimental results are presented.

In recent decades, two research themes have been prominent in the academic and organizational setting: lean manufacturing and green management. Since 1996, when Florida (1996) wrote an article focusing on the synergy between these two areas, the debate if “Lean is Green?” enters in the academic field. It is in this context that this research presents the results of a systematic literature on the topic, focusing on the characteristics, positive and negative impacts, lean paradigms, green paradigms and design of supply chains. To perform this procedure it were followed the methodological footsteps of Lage Junior and Godinho Filho (2010). The research occurred in the database Scopus and it was conducted from June, 2012 to July, 2012.The key word used was “green lean” and as search filter it were included only articles and conference Papers. Their main result is a deep analysis of the accumulated knowledge on the subject, where it is revealed that the majority of studies point to the synergy between some components of the lean manufacturing system in relation to environmental management. The research gap found is related to articles that address the entropy of the union of lean and green systems.

Understanding dance in all its educational aspects, creative and liberating, this of course work completion back motivating information for new studies and reflections. This study did a literature review to contextualize and detail reach the story and how it perpetuates in practice the dance style Waacking, sought the understanding of how the body is inserted in our society, made notes on the Sport Psychology regarding the topic fear and shame, and pledged to address the conflicting issues of gender and sexuality, to then be possible to develop what has been objectified. This study sought to establish whether there are national publications on the Waacking dance style and what their contributions to the Brazilian context, verifying the presence of stereotypes and prejudices to males in it are inserted. As used method, the survey was conducted in online databases having the following sites as a source of scientific academic content to nationwide: Google Scholar (like the filter to search only in Portuguese language - as the focus of the research is to gather national publications); Journals Portal CAPES / MEC; and SciELO - (Scientific Electronic Library Online). The review process took place using the categorization model, which was essential to be able to extract the information that met relevant from the criteria that have been pre-established, thus enabling the completion of this work Completion of course

Mastitis is an acute or a chronic inflammation of the udder, represented for physical, chemical and bacteriological milk alterations. It is notable that ovine milk represents high economic importance, and it can be used in the production of cheeses and other derivates, contributing for the farmer’s recipe enlargement. However, the mastitis in animals can determine the reduction of milk quantity and quality in infected animals. This may determine lambs’ weight loss and increase animal’s mortality. By the other hand, considering Public Health issues, mastitis can cause milk nutrients losses and promote the microorganisms’ multiplication that may lead to diarrheas and to other zoonosis in humans. This study aimed to evaluate 159 sheep mastitis status in 20 small farms located in Bauru (SP) region. Of the 309 colected samples, in 97 (31.4%) were isolated microorganisms of the genus Staphylococcus sp., which them 27.5% being coagulase negative Staphylococcus and 3.9% coagulase positive Staphylococcus. Of 177 isolates, 97 (54.8%) were represented by the genus Staphylococcus sp., which them 57 (58.8%) from pure culture and 40 (41.2%) in association. Most agents isolated were sensitive to antibiotics used in the test. Thus, we could verify the isolation of infectious microorganisms such as coagulase positive and negative Staphylococcus and, as well in dairy cattle, preventive measures to obtain hygienic milk are extremely important in order to get a final product with quality and safe in food and microbiological point of view.

Mastits is considered uncommon disease in mares. Streptococcus equi, Staphylococcus sp., Corynebacterium sp., Actinobacillus sp., Nocardia sp. and enterobacterias are major microorganisms involved in equine mammary infections. The disease is commonly related to traumatic lesions in mammary glands and teats. Edema, fibrosis, masses to palpation of glands, and viscous to seropurulent milk are mainly clinical signs observed in affected animals. The diagnosis is based on clinical exam of mammary glands and microbiological culture of the milk. There are no standard to use of indirect exams on diagnosis, including California Mastits Test and Somatic Cell Count. Systemic antimicrobials are recommended in therapy, based on previous “in vitro” susceptibility microbiological test. No specific control measures are indicated in equine mastits. The present study reviewed the mastits in mares, with emphasis to etiology, epidemiology findings, clinical manifestation, diagnosis, treatment and control aspects.

Aiming at developing a tool for assessing the magnitude of farm animal health, an indicator named herd “animal health status” was built. To illustrate the construction of the indicator, serum samples were taken from 923 goats on 17 goat farms in the state of Sao Paulo, Brazil, where three diseases were evaluated along with their impact percentages: caprine arthritis encephalitis, toxoplasmosis and neosporose – all of an infectious and transmissible nature and the cause of considerable economic losses. The mathematical rationale underlying the building of the “animal health status” indicator ranks properties on a 0 - 100% scale in terms of disease positivity in the herd, with the lowest indicator value indicating the highest cumulative disease frequency (0% = all animals tested positive for the three diseases, 100% = all animals tested negative for all diseases). Anti-T. gondii, anti-N. caninum and anti-CAEV antibodies were tested using indirect immunofluorescence reaction (IIFR ≥ 16), Neospora agglutination test (NAT ≥ 25) and agarose gel immunodiffusion (AGID positive or negative), respectively. The animal health status of the farms ranged from 32.38% to 96.40% according to disease positivity. The animal health status value will have a direct reflection on the production chain both on and off the farm, providing not only great market advantages, due to how the expression of animal health will add value to livestock farms, as well as on the consumer who can check the quality of animal health at the beginning of the production chain.

The effect of the contaminant fungi Trichoderma sp. and Chaetomium olivacearum on the cultivation of the ABL 99/30 and ABL 04/49 isolates of A. blazei in two compost formulations made up with tyfton (Cynodom dactylon) and oat (Avena sativa) was evaluated. The experimental design was a totally randomized 2 x 2 x 3 factorial design with 6 repetitions. The experimental unit consisted of 12-12.5 kg of wet compost. During the spawning, 150 g of Trichoderma sp. and C. olivacearum were added to the compost. The experiment was carried out in a climatized room, with humidity between 75-90% and temperature of 28º C. The productivity averages of the ABL 99/30 isolate of A. blazei were higher than those of ABL 04/49 and Trichoderma sp. and C. olivacearum negatively influenced the production of A. blazei. The different composts (based on tyfton and oat straw) did not influence the production of basidiomata.

The aim of this work was study the selectivity of insecticides in favor of natural enemies in cotton (Gossypium hirsutum latifolium Hurtch Lr), DeltaOpal cultivar, in the city of Malhada (BA), and to know the associated beneficial fauna. The study was conducted at the agricultural year of 2010/2011. The design was conducted in randomized blocks with six treatments and four replications. The treatments were: (1) Fipronil 200 SC (0.38 L.ha-1); (2) Alphacypermethrin 100 SC (0.30 L.ha-1), (3) Lufenuron 50 EC (0.30 L.ha-1), (4) Imidacloprid 200 SC (0.30 L.ha-1), (5) Methyl parathion 600 EC (1.00 L.ha-1), and (6) control (water). The product was applied 80 days after emergence, and the evaluations were performed one day before application and 1, 7 and 14 days after application (DAA). The samples were taken using the sampling method beating cloth and Moericke traps. Natural enemies were brought to the laboratory for sorting, counting and identification by family. The toxicity of the products ranged according to the group of natural enemies. Imidacloprid is selective to the spiders and insecticides are moderately toxic (Methyl Parathion and Alphacypermethrin: 1 and 14th DAA; Lufenuron: 14th DAA) or toxic (Fipronil and Alphacypermethrin: 7th DAA). Fipronil (1 DAA), Alphacypermethrin (7th DAA) and Methyl Parathion (14th DAA) are moderately toxic to adult ladybirds. The analyzed insecticides are toxic to the larvae of ladybirds, with more impact until seven days after the application, with the exception of Methyl Parathion classified, as innocuous until this period. The occurrence of 13 families of spiders and 18 families of parasitic Hymenoptera is registered in cotton agroecosystems in the region of Malhada, in the state of Bahia.
