Abstract: Background: Indoor air quality in environments where there is great circulation of people, posing risks to the health of its occupants, including allergic problems, infections and contaminations, can be aided by climatic factors, chemicals and biological agents housed in these environments, influencing the location and providing favorable conditions for the degradation of bibliographic collections. The present study investigated the presence of fungi in indoor environments in seven public and private libraries in the central region of Brazil, Mato Grosso, and verified the impact on occupational health. Results: A total of 26,194 fungal specimens were isolated from 342 dust samples collected using three techniques: Andersen’s sampler (12.3%), exposure plate dish (25.1%) and sterile swab (62.6%). A total of 184 fungal species were identified: 156 (84.8%) mycelial fungi and 28 (15.2%) yeast fungi, belonging 54 fungal genera, 43 (79.6%) mycelial fungi and 11 (20.4%) yeast fungi. The genus Aspergillus (40.6%) was one of the main fungi present in indoor air. Aspergillus niger (12.3%) was identified as the most prevalent species in literary environments, followed by Cryptococcus spp. (7.1%) and Cladosporium cladosporioides (7.0%). In relation to seasonal distribution, there was a greater fungal isolation in the dry season (54%); followed by the rainy season (46%). Conclusion: These results suggest the substrates researched in the evaluated environments presented in the form of documents, books and papers associated with dust and air humidity become suitable for microbiological proliferation. These findings highlight the importance of minimizing the risk of exposure to fungal agents, identified in pathogenic and toxigenic microenvironments in library collections.

Abstract: one alleges that the robin hood act has allowed one better distribution of the values of icms to municipalities of the state of minas gerais. the paper is aimed at verifying if the robin hood act has actually revealed a redistributive effect in tax transfers to municipalities in the state over the period 2001-2005, that is, if, in relative terms, poor municipalities have received more these transfers than rich ones. in doing methodologically so, an exploratory spatial data analysis and a convergence analysis are implemented to verify if the disparities of tax redistribution have diminished over the time. the findings showed that the spatial effects were important in the analysis as well as there was no redistributive effect in the period because the convergence coefficient was not significant.

Abstract: Oxygen uptake (VO2 peak) has been very important in functional assessment of cardiorespiratory fitness. The Ergospirometry is a noninvasive procedure used to evaluate physical performance or ability of an individual, through the analysis of the gases with the respiratory variables. In sports, this method of evaluation is crucial, because it brings a significant contribution to the verification of aerobic fitness, such as, the maximal oxygen uptake (VO2 max.), and anaerobic threshold. The present study aims to evaluate the power and aerobic capacity in professional and under-20 soccer players, handball athletes, and women footballers, using the technique of gas analysis. For the study, 48 athletes, who participated voluntarily, were divided into 4 groups of 12 athletes. The VO2 peak, the average speed and heart rate at anaerobic threshold, as well as respiratory exchange ratio were analyzed. We found that the values were always greater for the group of professional football players, with the exception of the average consumption of maximum O2, where the difference of the footballers in the under-20 category was not significant. Additional values that were analyzed indicated that there were some physical similarities between the other groups that should be noted. The respiratory exchange ratio was significantly lower for the group of women footballers. Based on this data, it was concluded that the specificity of sport as dimensions of the pitch, duration, and tactical system, morphology and sex of the athlete, directly influences the values of the VO2 peak, lactate threshold and respiratory exchange ratio for athletes of different sports at the same stage of periodization of fitness.

Abstract: the aim of the present study was to analyze the validity of predictive equation proposed by cureton et al. (1995) for vo2peak = -8.41 (mrw) + 0.34 (mrw) 2 + 0.21 (age x gender) -0.84 (bmi) + 108.94" on estimating the vo2max of young brazilians from a 1600-m running performance, and to suggest a predictive equation specific for this population. 30 physically active young men (23±3.1age; 74.8±5.8kg; 1.78±0.05m; 49.8±6.5ml.kg-1.min-1) who were submitted to an incremental exercise test (it) on treadmill until exhaustion with gas analysis participated in this study. subjects also performed a 1600-m running track test as fast as possible. the volunteers were randomly sorted in two groups: g1 - to generate a specific predictive equation for vo2max, and g2 - to apply both predictive equations (actual and from cureton et al.) to evaluate their validity on estimating vo2max in a brazilian population sample. significant differences were observed between vo2max directly identified on it through gas analysis (50.1±7.1 ml.kg-1.min-1) in relation to the results obtained by the predictive equation proposed by cureton et al. (1995) (44.2±6.5ml.kg-1.min-1) with a weak relationship between them (r = 0.21). the relationship between the vo2max on it and the running velocity on 1600-m as obtained for g1 resulted in the following predictive equation: (vo2max = 0.177*1600vm(m.min-1) + 8,101). when this new equation was applied on the participants of g2, the predicted vo2max (50.1±7.2ml.kg-1.min-1) did not differ from vo2max determined directly on it (50.1±7.1ml.kg-1.min-1) with a high correlation between them (r = 0.81). thus, it was concluded that the cureton et al. predictive equation developed with a north americanpopulation sample as grounding, underestimated the vo2max of physically active young brazilians. on the other hand, the predictive equation proposed on the present study was considered valid for this purpose through the 1600-m running performance for our participants.

Abstract: Since the late 1990’s vegetable oils have been conquering an increasing importance in the world.In virtue of reducing the CO2 emissions and promoting regional development, the biodieselemerges as a viable alternative. Hence this articleappraises the productivity of vegetable oil forthe production of biodiesel in the Zona da Mata Mineira over the period 2005/2006, using theexploratory spatial data analysis. In order to measure the productive potential of vegetable oil atthe regional level, one calculates the content of oil for each vegetable and these contents aresummed up to obtain the total of vegetable oil. Clusters were identified for the production ofvegetables both the high efficiency and low efficiency. The finding reveal the possibility ofgenerating jobs in most regions within Zona da MataMineira. Hence one observes the plantation ofvegetables for the production of biodiesel is highly viable in the Zona da Mata Mineira

Abstract: the cases of equidae acute abdomen diagnosed in the veterinary hospital of the federal university of campina grande, in the semiarid of the brazilian northeast were reviewed. from january 2001 to december 2011, 70 (4.5%) equidae out of 1542 were affected by colic, including 60 horses, 4 mules, and 6 donkeys. large colon impaction diagnosed in 37.14% of the cases was the most frequent cause of colic, followed by small colon impaction (10%) and foreign body in the small colon (7.14%). in four cases, colics were caused by phytobezoars in the large gut, two of which were associated with the ingestion of large amounts of fresh prosopis juliflora pods. six cases of colic by foreign bodies, mainly plastic bags, were observed, five located in the small colon and one in the large colon. strangulating small intestinal lesions were observed in four cases. other causes of colic were spasmodic colic (two cases due to gastrointestinal parasites and two due to consumption of home residues), and gastric impaction (three cases). large colon displacement was diagnosed twice. laceration of the small colon, cecal torsion, and bloat by ingestion of manihot esculenta were diagnosed once. the main risk factor for the occurrence of colic was the ingestion of choped pennisetum purpureum, brachiaria spp., sorghum spp. or echinochloa polystachya (or=4.03; p=0.007). as a result of the low quality of the foods the frequency of colic was significantly higher during the dry season (second semester) (or=2.61; p<0.01). it is concluded that feeding with low quality forages during the dry season contributes with the high frequency of cases of colic in the brazilian semiarid, and that is necessary to improve food quality and food management to try to decrease the frequency of this syndrome in the region.
