Abstract: a greenhouse experiment was conducted to study the effect of boron in dry bean plants (phaseolus vulgaris l.) grown in pots. the treatments consisted of 0, 1, 2, 4, 8, and 16 kg.ha-1 of boron in the form of borax. two identical experiments were carried out during the winter (june/july) and the spring (september/october) seasons. in the winter experiment, the boron deficiency symptoms were shown only by the control plants. in those conditions, the high concentrations of ca and mg and the low temperatures affected the boron absorption of the plants. the application of 1 kg.ha-1 of boron was sufficient to reduce the visible symptoms of b deficiency, and increased the dry weight of the shoots. at the rate of the 2 kg.ha-1 b or above there was excess of boron in the dry matter of the shoots. in the spring experiment there was no deficiency symptoms in the plants and the boron concentration was adequate in the shoots. also, the application of 2 kg.ha-1 of b or more increased the b concentration to excess. the results suggest that boron deficiency is relevant only in the winter and that excess of boron is a problem, causing toxicity, independent of the season.

Abstract: during the year 1986/87, experiments were conducted at the experiment stations of mococa and ribeir?o preto in the state of s?o paulo, brazil. the objective was to evaluate the effect of four rates of lime (0, 4, 8 and 12t/ha) on the concentrations of oil and protein in the seeds of the following soybean cultivars: iac-foscarin-31, iac-11, iac-12, and cristalina. the maturity group varied from 130 to 160 days. the results showed that highest concentration of oil and protein was observed in seeds harvested at mococa. independently of liming and locality the cultivar iac-12 presented the highest average production of oil and protein per area (561 and 963kg/ha, respectively). in both experiments, addition of lime resulted in raise of seed protein but in consistent decrease of seed oil for all cultivars. the quantity of oil and protein per area increased linearly with the increase in the rates of lime. this occurred as a result of the increase in seed yield after reducing soil acidity.

Abstract: objective:to analyze the impact of the contraindications for heart transplantation in mortality and survival time after partial left ventriculectomy. method: a prospective clinical study of a cohort of 43 patients submitted to partial left ventriculectomy, in whom there were contraindications for heart transplantation was performed. the following contraindications were analyzed: psychological, sociocultural, age of 65 years of age and older, elevated pulmonary arteriolar resistance and pulmonary arterial hypertension and the refusal or not for transplantation. these variables were tested for association with postoperative mortality and survival time after partial left ventriculectomy. statistical analysis included the chi-square test, kaplan-meier survival analysis, non-parametric log-rank test, cox regression model, 95% confidence intervals and p values (significant if less than 0.05). results: higher postoperative mortality rates for partial left ventriculectomy were found when the following contraindications of heart transplantation were present preoperatively: poor sociocultural conditions (p = 0.037), psychological disturbances (p = 0.037) and in patients who accepted heart transplantation even when counseled against this procedure (p = 0.017). survival time was significantly shortened in the presence of psychological disturbances (p = 0.0466), in patients older than 65 years (p = 0.0397) and in those who did not accept heart transplantation (p = 0.0306). elevated pulmonary arteriolar resistance and pulmonary arterial hypertension were not associated with higher mortality rates or shortened survival time. conclusion: some of the contraindications for heart transplantation adversely affected the mortality and survival time after partial left ventriculectomy, thus revealing the ineffectiveness of this alternative procedure in this subset of patients.

Abstract: necrotizing fasciitis is a rare soft tissue infection and a life-threatening emergency, often fatal. its incidence and management are described plentifully in the medical literature regarding the most common anatomical sites involved like the abdomen, lower and upper limbs, and perineum. however, available data and case reports of chest wall necrotizing fasciitis after thoracic procedures are scarce, mainly after major cardiac operations. we report and discuss a case of necrotizing fasciitis of the chest wall occurring in the immediate postoperative period of a cardiac procedure, and include a brief review of the concepts, pathophysiology, and treatment reported in the medical literature. we emphasize the need for early diagnosis and urgent and effective surgical debridement. of importance is the fact that we have not found any references in the literature to cases similar or equal to the one we describe here, which occurred in the postoperative period of a cardiac procedure.
Association of HTLV-I with Arnold Chiari syndrome and syringomyelia
Viana, Gra?a Maria de Castro;Diniz Neto, Jo?o Arnaud;Furtado, Igor de Sousa;Binda Júnior, José Roberto;Tanaka, Bárbara Neiva;Nascimento, Maria do Desterro Soares Brand?o;
Brazilian Journal of Infectious Diseases , 2008, DOI: 10.1590/S1413-86702008000600018
Abstract: htlv-i is associated with a broad spectrum of manifestations, including tropical spastic paraparesis and adult t-cell leukemia/lymphoma. arnold chiari syndrome is a condition characterized by herniation of the cerebellar tonsils through the foramen magnum. this condition should be suspected in all patients with headache and impaired motor coordination. syringomyelia is a developmental anomaly that leads to the formation of an intramedullary cavity. its clinical presentation is classically characterized by syringomyelic dissociation of sensation, with suspended distribution in the proximal portion of the trunk and upper limbs and preservation in other regions. we report here a case of association of the three diseases, which is rare in clinical practice, illustrating the difficulty in the diagnosis and therapeutic management of these conditions.

Abstract: the objective of these experiments was to study the effect of nitrogen and potassium fertilizations on the response to nodulation, nitrogen fixation, nitrogen seed content and yield of two soybean cultivars planted during the winter season. they were installed on the following soils: eutric lixisol (mococa) and rhodic ferralsol (ribeir?o preto and votuporanga, sp, brazil). the treatments consisted of three rates of nitrogen (0, 50 and 100 kg.ha-1 of n) as urea, three of potassium (0, 30 and 60 kg.ha-1 of k2o) as chloride and two soybean cultivars (iac-8 and iac-14). the experimental design was a random factorial with four replications. soybean seeds of all treatments were inoculated with a commercial inoculant. at flowering, plants were sampled to evaluate nodulation and nitrogenase activity. at maturity, plants were harvest and seeds weighed.the results showed that inoculation did not provide the amount of nitrogen required to maximize soybean yield in the winter. the nitrogen treatment reduced nodulation and nitrogen fixation, but increased seed yield at the three localities. potassium fertilization did not have any significant effect on nodulation, nitrogen fixation and yield of soybeans. increased however dry matter weight and number of nodules of the cultivar iac-14.
Lot Sizing in Production Scheduling at a Personal Protection Equipment Company  [PDF]
José Roberto Dale Luche, Rodolfo Egon Perhs
American Journal of Operations Research (AJOR) , 2016, DOI: 10.4236/ajor.2016.65035
Abstract: This work presents an optimization model to support decisions during production planning and control in the personal protective equipment (PPE) industry (in particular, gloves). A case study was carried out at a Brazilian company with the aim of increasing productivity and improving customer service with respect to meeting deadlines. In this case study, the mixed integer linear programming model of Luche (2009) was revisited. A new model for single-stage lot sizing was applied to the production scheduling of gloves. Optimizing this scheduling was not a simple task because of the scale of the equipment setup time, the diversity of the products and the deadlines for the orders. The model was implemented in GAMS IDE and solved by CPLEX 12. The model and the associated heuristic produce better solutions than those currently used by the company.

Tanaka, Eliza Dieko Oshiro;Manzini, Eduardo José;
Revista Brasileira de Educa??o Especial , 2005, DOI: 10.1590/S1413-65382005000200008
Abstract: the aim of this study was to identify the view of the employers about the deficient people, their job and their admission in the company. the data were collected by semi-structured interview with six persons responsible for the human resources department. the branches of these companies were commerce, industry and services. results indicated that the enterprises had employers with different kinds of deficient and their admission was done because of the working laws. the people interviewed believed that the deficient once had conditions for working but they pointed out some difficulties like: a) lack education, interest and social and professional preparation of the deficient employee; b) inadequate physical and social conditions of the company and little knowledge of deficiency; c) inadequate professional and social training programs and awareness of the company needs; d) no access to school and transportation, no incentive for the company to promote ergonomic adaptation and development social responsibility programs. the position that the deficient staff had required little qualification and the training was taken in the workplace. the conception that their difficulties were caused by their organic conditions was in all the interviews.
