The use of organic wastes, as an alternative to inorganic fertilizer, can be an important strategy for Brazilian and tropical agriculture. Despite the importance, few field studies have been done for evaluating organic amendments on soybean crops in Brazil. The study aimed to evaluate the residual effects of the organic amendments poultry litter, farmyard manure and biochar combined with mineral fertilizer on some agronomic attributes of a soybean crop. A field experiment was carried out in a split-split-plot scheme, with three replicates in a randomized block experimental design. The organic sources (plots) at rates of 0, 3, 6 and 9 Mg·ha-1 (subplots) combined with 0, 100, 200, 300 and 400 kg·ha-1 (sub subplots) of a mineral fertilizer were applied in 2008. In 2009, only the mineral fertilizer was used on the soybean crop. As a?result, all evaluated attributes were influenced by the treatments, except for the number of grains per pod. The application of poultry litter provided the highest yield (3715 kg·ha-1 using 9 Mg·ha-1 of the source). A synergistic effect between organic amendments and mineral fertilizer was observed. It was found the possibility of decrease doses of mineral fertilizers by prior use of organic amendments. The most effective dose combination application is 5.5 Mg·ha-1 of organic amendments associated with 200 kg·ha-1 of mineral fertilizer to provide optimum yield. The use of organic amendments, rich in nutrients, is a technology to sustainably increase the soybean grain yield.

American Journal of Plant Sciences 2014年第20期5卷 2929-2934页

作者： Rejane Teixeira do Nascimento Bruno Ettore Pavan Luciana Barboza Silva Gabriel dos Santos carvalho alexandre Faria da Silva Kellen Maggioni Graduate Program in Agronomy-Crop Science Federal University of Piauí Bom Jesus Brazil College of Engineering of Ilha Solteira—DFTASE—UNESP S&atildeo Paulo Brasil

This study aimed to assess the resistance of grain from two varieties of maize landraces in initial breeding in Bom Jesus-PI, with respect to S. zeamais attack. Seeds of two maize landraces were used: purple straw maize from two different origins (São Paulo (SP) and Espírito Santo (ES)) and Peruvian purple maize. The experimental design was completely randomized with four replications. The data for each response variable were subjected to analysis of variance, applying the F-test (p ≤ 0.05), and when significant differences were found, there was a comparison of means by Tukey test (p ≤ 0.05). The statistical analyses were performed using the software SAS®. In a free-choice test and bioassay for evaluating the nutritional index (no choice test), maize varieties differed significantly by Tukey test and the cultivar SP was considered resistant, while the cultivars purple and ES were considered susceptible.

Background: Healthcare-associated infections affect hundreds of millions of patients worldwide. Children have greater susceptibility to healthcare-associated infections due to the immaturity of their immune system. Contact precautions aim to promote safety, protection and prevention of contamination. Thus, the objective of this study was to verify adherence to contact precaution measures, as well as compliance to the use of personal protective equipment. Methods: This cross-sectional observational study was carried out from July to October 2019 using a checklist to evaluate health professionals’ adherence to hand hygiene procedures and the use of gloves and surgical gowns when assisting children on contact precautions. Results: A total of 941 observations were carried out in a total of 300.532 hours. Hand hygiene was performed before and after contact with the patient in 58.84% and 75.09% of the cases, respectively and a surgical gown was used in 86.40% of the cases. The use of gloves was the variable most adhered to by professionals (87.57%). Intensive care unit professionals were the care workers who most complied with the regulation regarding hand hygiene after contact with the patient (p = 0.009) and the use of the surgical gown (p < 0.001). The correct hand hygiene technique was the recommendation with least adherence. Non-compliance to the hand hygiene technique was statistically significant among intensive care unit professionals (p = 0.002). Conclusions: Adherence to hand hygiene before contact with the patient and compliance with the hand hygiene technique were neglected by most professionals. However, there was good adherence to the use of surgical gloves and gowns, as well as high compliance to the techniques of removing these items. .

Journal of Energy and Power Engineering 2014年第3期8卷 508-514页

作者： alexandre Piantini Thais O. de carvalho Paulo F. Obase Jorge M. Janiszewski Gilnei J. G. Santos Donorvan R. Fagundes Institute of Energy and Environment University of Sao Paulo Sao Paulo 05508-010 Brazil Polytechnic School University ofS6o Paulo S6o Paulo 05508-010 Brazil AES SUL Coordination of Planning and Engineering S6o Leopoldo 93010-060 Brazil

In the period 2003-2011, lightning over-voltages accounted for about 47% of the total number of distribution transformer failures observed in the service area ofAES Sul, a power company that operates in the state of Rio Grande doSul, in South Brazil. This paper presents the results of an investigation on the influence of the distance between transformer and MV arresters on the surges at the transformer windings caused by direct strikes to the MV network. The analysis, performed through simulations using the Alternative Transients Program, shows that in general higher voltages are produced by subsequent strokes. Although in relation to the primary side the surges transferred to the secondary are much less affected by the distance between transformers and primary arresters, such distance should always be kept as short as possible in order to reduce the probability of occurrence of transformer failures due to over-voltages at the MV bushings.

The Effect of High Carbohydrate Consumption on Glucose Levels and Antibody Production in Nonobese Diabetic Mice

引用

Food and Nutrition Sciences 2016年第10期7卷 866-873页

作者： Tonicley alexandre da Silva Caio José de carvalho-Filho Elizabeth de Sousa Barcelos Barroqueiro Deysianne Costa das Chagas Flá via Raquel Fernandes Nascimento Rosane Nassar Meireles Guerra Laboratory of Imunophysiology Universidade Federal do Maranh&atilde o S&atilde o Luí s Brazil

The aim of this study was to evaluate the effect of chronic treatment with diets rich in carbohydrates on the IgM and IgG antibody production and the seric glucose concentration in diabetes. Nonobese diabetic (NOD) mice received, ad libitum, by oral route, the diet consisting of an aqueous extract (20 mg/mL) of the following flours: babassu mesocarp, manioc, corn or rice, during 120 days. The diet intake was monitored throughout this period. At the end, the weight variation, blood glucose, serum IgG and IgM antibody and IgM anti-insulin titers, were determined. The babassu and manioc flour extracts altered Purina chow intake and these animals also presented a significant increase in body weight. In contrast, treatment with rice flour resulted in a significant weight loss. Moderate to severe hyperglycemia was observed in the groups receiving rice and manioc, whereas treatment with babassu mesocarp flour and cornmeal resulted in hypoglycemia. The extracts did not alter the IgG concentration. On the other hand, the cornmeal extract caused a marked reduction in both total IgM and anti-insulin IgM antibody production. Although babassu mesocarp flour, cornmeal and manioc flour caused important variations in the parameters studied, only treatment with the rice flour extract anticipated the onset of diabetes in male mice genetically predisposed to the disease.

A Risk-Adjusted Retrospective Data Analysis between Younger and Elderly Patients with Acute Coronary Syndromes—Long-Term Prognosis

引用

Open Journal of Emergency Medicine 2016年第3期4卷 53-61页

作者： alexandre de Matos Soeiro Alyne Pinto Borba Aline Siqueira Bossa Cindel Nogueira Zullino Maria Carolina Feres de Almeida Soeiro Tatiana de carvalho Andreucci Torres Leal Carlos V. Serrano Múcio Oliveira Tavares Emergency Care Unit Heart Institute (InCor) University of S&atilde o Paulo Medical School S&atilde o Paulo Brazil

Purpose: To compare the demographic data and outcomes of younger versus elderly patients with acute coronary syndromes. Methods: This was a retrospective data bank analysis study with 966 patients (268 in the younger group (less than 55 years) and 698 in the elderly group (more than 55 years)). Data were obtained about clinical characteristics, angiography, and medication used at hospital and coronary definitive treatment. The primary endpoint was all cause of in-hospital death and combined events. Comparison between groups was made by Anova and Q-square. Multivariative analysis was determined by logistic regression and was considered significative when p < 0.05. Long-term mortality and combined events were studied using Kaplan- Meyer curves with median follow-up of 11.21 months. Results: The median age in the younger group was 48 years versus 69 years in the elderly group. In the younger group 26% was ST-myocardial infarction versus 18% in the elderly group. About 7% of younger patients were submitted to coronary bypass surgery and 42% to percutaneous coronary angioplasty versus 12% and 25% in elderly group, respectively. Significant difference was observed between the younger versus elderly groups in deaths (1.5% × 7.5%, p = 0.004), combined events (14.9% × 26.3%, p = 0.02) and killip III/IV (3.7% × 8.3%, p = 0.04). Long-term mortality was 3.7% × 10.2%, p = 0.01). Conclusions: In patients with acute coronary syndromes age was an important predictor factor of mortality and complications. Significative differences in outcomes were observed between the two groups in-hospital and long-term follow-up.

Background: Photodynamic therapy (PDT) is the generation of cytotoxic agents through the dynamic interaction between a photosensitizer excited by light at a specific wavelength. When associated with phthalocyanines, they are efficient in incorporating target cells and exhibiting high rates of triplet generation. This study aimed to characterize PDT associated with the phototherapeutic agent Phthalomethyl D, developed by the authors, in the process of repair, healing and immune improvement for possible application against SARS-CoV-2. Methods: Sixty-nine mice were used, divided into 2 groups: GI, treated with ILIB laser, without a phototherapeutic agent, and subjected to surgery for viral induction;GII, same as GI plus association of Phthalomethyl D. They were divided into subgroups and reevaluated at 7, 14, and 21 days, and then divided into 3 subgroups of 6 animals each, subjected to treatment at 24 h, 48 h, 72 h, 5 and 7 days. Results: Both groups had a high rate of partial incision closure and acute inflammatory control. Microscopically, there was a greater amount of amorphous fundamental substance, fibrocytes, fibroblasts, and giant cells and reduction in the number of keratinocytes, in the amount of keratin, and epidermal thickness in GII than in GI. Conclusions: PDT with Phthalomethyl D stimulates the processes of healing/repair and immunomodulation during viral infection, initially favoring the inflammatory response and, after 21 days, contributing to the anti-inflammatory response profile, making this approach possible in the treatment of individuals infected with SARS-CoV-2.
