title: Roughage-free finishing diet based on whole corn grain and a mixture of additives for Nellore heifers

description: ABSTRACT This study was carried out to evaluate the effect of a blend of additives (choline, methionine, selenium, and organic zinc) on performance, feed efficiency, rumen parameters, and carcass traits of Nellore heifers finished with roughage-free diet. Nellore heifers (n = 36; average BW = 244±24.1 kg; average 24 months of age) were maintained in a feedlot system for 86 d. Heifers were separated into two groups: control and additive. Heifers in control group were fed a based diet composed of 850 g kg−1 corn grain and 150 g kg−1 of a mineral-vitamin-protein pellet. The additive group was fed a diet supplemented with a blend of choline, methionine, selenium, and organic zinc at 1,667, 4,000, 1, and 24.37 mg kg−1 of the diet dry matter, respectively. The animals were allotted to 18 pens (two heifers/pen), with nine pens per treatment. Heifers were weighed, blood samples were collected, ultrasonography examinations were performed periodically, and hot carcass and papillae samples were taken at slaughter. Data were analyzed as a completely randomized design. The model included the fixed effect of treatments (control and additive). Additive supplementation did not change dry matter intake, performance, or feed efficiency. There was no effect of additives on muscle or fat tissue deposition. Consequently, no changes in hot carcass weight and dressing were found. Overall, additive inclusion did not alter blood parameters, blood electrolyte balance, and rumen traits. Nellore heifers finished with roughage-free diets have no improvement on production traits nor in their rumen health by supplementation with a blend of choline, methionine, selenium, and organic zinc.

title: Restructuring in the flow of textile wastewater treatment and its relationship with water quality in Doce River, MG, Brazil

description: Abstract Textile industries use large amounts of water in the processes of dyeing and processing of textile fibers, generating high volumes of wastewater containing dyes, surfactants, inorganic ions, wetting agents, among others. The main environmental impact of these effluents is related to the absorption of light into the water, which interferes with the photosynthesis of plants and algae. Therefore, it is relevant to have environmental planning aimed at the reuse of the water, increased removal of dyes, as well as reducing losses in the dyeing. In this work, studies were undertaken to propose control measures so as to introduce the concepts of Cleaner Production (CP) in the textile sector. Data was collected in a company located in the catchment area of the river Doce, in Minas Gerais, and established the association of the relative advantages of conventional coagulation/flocculation with the combined use of Advanced Oxidation Processes (AOP). The proposed measures entail a decrease in the volume and characteristics of the refractory sludge generated and the possibility of recirculation of treated effluent. The need to develop pilot-scale experiments was identified, including monitoring of the acute toxicity of treated effluents.

title: Novel retrograde puncture method to establish preperitoneal space for laparoscopic direct inguinal hernia repair with internal ring suturing

description: The aim of this study was to explore the clinical efficacy of a novel retrograde puncture approach to establish a preperitoneal space for laparoscopic direct inguinal hernia repair with inguinal ring suturing. Forty-two patients who underwent laparoscopic inguinal hernia repair with retrograde puncture for preperitoneal space establishment as well as inguinal ring suturing between August 2013 and March 2014 at our hospital were enrolled. Preperitoneal space was successfully established in all patients, with a mean establishment time of 6 min. Laparoscopic repairs were successful in all patients, with a mean surgical time of 26±15.1 min. Mean postoperative hospitalization duration was 3.0±0.7 days. Two patients suffered from postoperative local hematomas, which were relieved after puncturing and drainage. Four patients had short-term local pain. There were no cases of chronic pain. Patients were followed up for 6 months to 1 year, and no recurrence was observed. Our results demonstrate that preperitoneal space established by the retrograde puncture technique can be successfully used in adult laparoscopic hernioplasty to avoid intraoperative mesh fixation, and thus reduce medical costs.

title: Coverage of food intake assessment in the Brazilian Food and Nutrition Surveillance System: 2008 to 2013

description: ABSTRACT: Introduction: In Brazil, the Food and Nutrition Surveillance System (Sistema de Vigilância Alimentar e Nutricional - SISVAN) provides continuous data on the nutritional status and food intake of the population user of primary health care to elaborate actions, programs, and policies. Objective: This article describes the percentage of registration in the system, percentage of use, and coverage of food intake monitoring between 2008 and 2013. Methods: This is an ecological study that characterizes the registered population according to federation units, macro-regions, and/or life stages. The indicators used were percentage of registration and use and coverage. The analysis used descriptive statistics, a linear regression model, and Spearman’s correlation. Results: In 2010, approximately 100.00% of the cities had at least one individual registered in the system while the percentage of use was 22.4%. National coverage ranged from 0.13 to 0.4% between 2008 and 2013, with a statistically significant increasing trend. The Midwest showed the highest regional coverage. All life stages presented increasing coverage trend, especially children and pregnant women. Conclusion: Despite the continuous data collection, food intake assessment proved to be incipient, and its distribution in the cities was low. Implementation of the National Food and Nutrition Policy can be enhanced by overcoming central issues, such as physical structure and training of professionals, which prevent the progress of system consolidation.

title: Effect of oil palm (Elaeis guineensis Jacq.) plantations on individual-level diet variation of Hylaeamys megacephalus (G. Fisher 1814) (Rodentia, Cricetidae) in eastern Amazon Forest

description: Abstract: In this study we described the diet of Hylaeamys megacephalus (G. Fisher, 1814) and investigated the degree of individual variation in the diet of this species among the Amazon Forest and the oil palm plantation. We analyzed the stomach contents of 36 individuals, of whom 11 were collected in the forest and 25 captured in the palm oil palm plantation. The H. megacephalus diet consisted of 18 food items, of which 12 were animal composition and eight were vegetable composition. The niche amplitude of the species was narrower in the forest area (Baforest = 0.013) compared to the palm tree plantation area (Bapalm = 0.478). This shows that individuals have greater niche overlap in forest areas, while in the plantation areas the animals expand their food niche. In addition, the values of the mean of the individual diet in relation to the diet of the entire population were lower in the palm oil palm plantation environment (ISpalm = 0.164) than in the Forest environment (ISforest = 0.357), indicating a high specialization in the palm oil plantation. These results indicate a population mechanism to reduce intraspecific competition in response to scarce resources.

title: Obstetric profile of perinatal deaths on a capital of the Northeast of Brazil

description: Abstract Objectives: to analyze the obstetric and sociodemographic profile on perinatal deaths in Teresina the capital of Piauí, from data obtained from the Sistema de Informação de Mortalidade e Sistema de Informação de Nascidos Vivos (Brazilian Mortality Information System and Livebirth Information System). Methods: this is a retrospective cohort on perinatal deaths of mothers whose babies were born and resided in Teresina between 2010 and 2014. The analyzed variables were age and the mother´s schooling, gestational age, type of pregnancy (singleton or multiple), route of delivery (vaginal or cesarean), place of death (in and out hospital), time of death in relation to the delivery (prior, during or after), and birth weight. Results: the perinatal mortality coefficient (PMC) varied from 17.5 to 19.3 per 1,000 births. We found similarities in the sociodemographic profile and in the obstetric fetal and non-fetal deaths, both with a great incidence on 20 to 27 years-old mothers, vaginal delivery and singleton pregnancy. Low birth weight was positively related to early neonatal deaths. Conclusions: perinatal mortality presented a statistical correlation in gestational age, birth weight, and type of delivery. The PMC in our study was higher than other Brazilian capitals.

title: Multidimensional physical quantities

description: Abstract In the present paper we present the continuation of the recent paper “One-dimensional physical quantities”, published in Revista Brasileira de Ensino de Física. The operational construction of a physical quantity passes through the definition of its domain, separation of the domain into equivalence classes and, finally, the injective association of equivalence classes into a value space. This formulation is outlined here to encompass multidimensional quantities, including vectors, dual vectors and tensors. Adopting an operational bias, in this case, allows us to re-signify seemingly tautological topics of mathematics, such as geometry and topology, from its connection to the physical world.

title: Preventable deaths in childhood, according to actions of the Unified Health System, Brazil

description: ABSTRACT: Objective: To analyze the mortality trend of children under five years of age living in Brazil and regions, using the “Brazilian List of Preventable Causes of Death.” Method: Ecological time-series study of mortality rate due to preventable and non-preventable causes, with corrections for ill-defined causes and underreporting of deaths from 2000 to 2013. Results: In Brazil, preventable death rates (5.1% per year) had a higher decrease compared with non-preventable ones (2.5% per year). Preventable causes associated with proper care during pregnancy had the highest concentration of deaths in 2013 (12,267) and the second lowest average percentage reduction in the year (2.1%) and for the period (24.4%). The South and Southeast regions had the lowest mortality rates in childhood. However, the Northeast region had the highest decrease in reducible child mortality (6.1% per year) and the Midwest, the lowest (3.5% per year). Conclusion: The decrease in childhood mortality rates was expected in the last decade, suggesting the progress in the response of health systems, in addition to improvements in health conditions and social determinants. Special attention should be given to pregnancy-related causes, i.e., expand the quality of prenatal care, in particular, due to fetal and newborn deaths resulted from maternal conditions, which increased significantly in the period (8,3% per year).

title: Physical, Chemical, and Microbiological Properties of Soil under Different Plant Covers in the Seridó Desertification Region in the Brazilian Semiarid

description: ABSTRACT The Seridó Desertification Region is a result of inadequate management of the native Caatinga vegetation, which generated degraded areas with little or no capacity for plant production. The area has experienced a succession of different land uses, but little is known about the impact of these changes. The present study tested the hypothesis that the intense degradation of the Caatinga drastically decreased vegetal biomass production, which favored direct soil exposure and resulted in a lower abundance and diversity of species and groups of vegetation as well as microorganisms. This study aimed to quantify some of the main physical, chemical, and microbiological properties of Alfisol ( Luvissolo Crômico órtico lítico ) and Entisol ( Neossolo Litólico eutrófico típico ) under different plant covers in the Seridó Desertification Region, in the municipality of Parelhas, in the state of Rio Grande do Norte (RN), Brazil. Three different areas were studied: an area of preserved Caatinga, a recovery area with jurema [ Mimosa tenuiflora (Willd.) Poir.], and a degraded area. Soil samples were collected from the 0.00-0.10 m soil layer and later characterized in terms of their physical and chemical properties. The microbiological characteristics analyzed were microbial activity (microbial biomass carbon and microbial respiration) and glomalin. The soil under the Caatinga vegetation exhibited better properties than the other analyzed soils. Aggregate stability was the physical property with the highest potential for differentiating between areas. Glomalin, which is associated with the presence of mycorrhizae, and which, in turn, is related to the uptake of P, which is often deficient in these soils, was the most discriminating microbiological variable according to an analysis of canonical variables. The total of Ca2+ and Mg2+ was the most discriminating chemical properties, and played a positive role in soil aggregation, especially Ca2+.
