Abstract: this research was developed in two swine housings in the phases of nursery and finishing: in two pens each, in two farms located at salto county, sp, with the objective to evaluate ammonia and concentrations, and fungi presence besides estimating the occupational risk of exposure to these environmental agents. the evaluations were done according to recommended by the norms nr-15, niosh e acgih. results indicated significant difference in ammonia concentration in relation to the hour, the housing and to the day period. they also indicate negligence to sanitary ventilation matter in nursery housing with consequent higher level of ammonia; which are linked to the air circulation inside housing, the manure and curtain management, housing typology, and to local climate conditions; besides swine crowd and density. total dust concentration was higher in nursery buildings (0.84-9.16mg.m-3) than in finishing (0.84-3.34mg m-3), while inhale dust was higher in the nursery, however lower than 3.67mg m-3, and within the labor welfare limits. there were found fungi from genus aspergillus, penicillium and neurospora in suspension in the internal environmental of the studied housings.

Abstract: production of one day-old chick production is one of the most important segments in the poultry production business. broiler chicken incubation environment needs to be homogeneous and adequate so hatchability and final product quality are not affected. this research aimed at evaluating environmental conditions inside a multi-stage setter in a commercial hatchery house. the incubator was split into six areas and data loggers placed in the geometric center to register temperature and relative humidity data; carbon dioxide concentration and number of colony forming units (cfu) of fungi were also sampled and analyzed; kruskal-wallis non-parametric test was used for statistical analysis; significant differences in temperature and relative humidity distribution inside the incubator (p < 0.05) were detected, but no differences were found in co2 concentrations or cfu distribution inside the incubator (p > 0.05). fungi incidence varied from average to good. critical points were detected in all areas inside the setter.
A simple method for the detection of recombinogenic substances in filamentous fungi

Abstract: several tests are available for detecting mutagenic and recombinogenic products in fungi. since fungi are eukaryotic, these tests permit the detection of substances that produce chromosomal aberrations, or that are recombinogenic. we have developed a new method for testing substances that affect fungal stability using a duplication strain of aspergillus nidulans and circular statistics for data analysis. the fungus was inoculated on the center of petri dishes and the substance to be tested was applied to a defined area of the dish. position of resulting sectors was measured by an angle and the data were analyzed by the rayleigh test. extensive testing with different compounds showed this method to be rapid and efficient for screening recombinogenic substances.

Abstract: objective: to investigate the frequency of rural occupational accidents and its association with potential risk factors. methods: the study was carried out in a urban area of pelotas, rs, brazil. a cross-sectional study was conducted. a representative sample of rural workers was selected using a multi-stage sampling. from january to april 1996, a total of 258 rural families were visited and all the 580 rural workers identified in those households answered a standardized questionnaire. results and conclusions: the prevalence of rural occupational accidents was 11%. after allowing for potential confounders, the main occupational hazards, as shown by logistic regression, were lower socioeconomic status (or=1.81), non-white skin color (or=3.50), and poor work satisfaction (or=2.77).

Abstract: The sonorous communicationis one of the first steps of theman in direction to the civility. At themoment, where it creates a new wayof expression, weaveing fromonomatopoeics sounds the elementsof a new language, it initiates theimmeasurable and definitive path ofthe word. It is, therefore, the songthe agglutinant element of this sonorouslight, that brings the man to thelight, that link it to Absolute andmake it the creator of itself.

Abstract: OBJETIVO: Investigar a ocorrência de acidentes do trabalho, na zona rural, e sua associa o com alguns fatores de risco. MéTODOS: O estudo foi realizado na zona rural do município de Pelotas, RS. O delineamento do estudo foi transversal de base populacional. Uma amostra representativa dos trabalhadores rurais foi obtida por meio de amostragem, em estágios múltiplos, utilizando-se os setores censitários da Funda o IBGE. As entrevistas foram realizadas em um período de quatro meses, utilizando-se questionários padronizados e pré-codificados. Os 580 trabalhadores entrevistados pertenciam a 258 famílias da zona rural. RESULTADOS E CONCLUS ES: A prevalência de acidentes encontrada foi de 11%. Os fatores de risco associados à maior ocorrência de acidentes, na análise multivariada, foram a classe social mais baixa (OR=1,81), a cor n o-branca (OR=3,50) e a insatisfa o com o trabalho realizado (OR=2,77).

Abstract: synapterpes (s.) hanleyi (pfeiffer, 1846) is characterized by anatomy, synonymy and geographical distribution. shell and soft parts were studied and important taxonomic characters evaluated and illustrated. these studies give conditions to characterize the species and include it in the genus synapterpes pilsbry, 1896 and distinguish s. hanleyi from the other species of synapterpes s.s. known only by their shells, respectively from brazil and colombia: s.(s.) coronatus (pfeiffer, 1846) and s.(s.) wallisi (mousson, 1869).

Abstract: The use of beneficial microorganisms in forage grasses is a potentially advantageous technique for a more sustainable pasture management by decreasing the need for chemical fertilization. Our aims were to determine the best method of microorganism inoculation on Brachiaria (Syn. Urochloa) brizantha cv. BRS Piata, compare the responses of inoculated plants of this forage grass with fertilized and unfertilized controls and examine its effect on some morphological, physiological and biochemical responses. On the first experiment, three inoculation methods were tested: in the seed, seed and soil, and soil, with Pseudomonas fluorescens (BRM-32111) and Burkholderia pyrrocinia (BRM-32113). In the second experiment, fertilized and unfertilized plants were either inoculated with BRM-32111, BRM-32113 and co-inoculated (BRM-32111 + BRM-32113). In a final experiment, B. brizantha was inoculated by soil drenching with BRM-32111, BRM-32113 and co-inoculated (BRM-32111 + BRM-32113), and compared to fertilized- and unfertilized-controls. The inoculation by soil drenching, at seedling stage, was more effective than inoculation only in the seed or both in the seed and by soil drenching. The fertilizer may have suppressed the beneficial bacterial effects on the growth of B. brizantha. P. fluorescens and B. pyrrocinia co-inoculated increased nitrate, protein, nitrogen concentration, Spad index (chlorophyll content), leaf area,
