title: Feeding behavior of sheep fed sugarcane silage enriched with detoxified castor bean meal

description: ABSTRACT. The aim of this study was to evaluate the feeding behavior of sheep fed sugarcane silage enriched with increasing levels of detoxified castor bean meal. Twenty-four non-castrated male Santa Inês sheep with an average body weight of 25.34 kg and four months of age, were distributed in four treatments - 0, 7, 14 and 21% of the natural matter of detoxified castor bean meal in sugarcane silage. There was a linear increase (p &lt; 0.05) in time spent eating and feeding and rumination efficiency (g MS and NDF/h) with the inclusion of castor bean meal in silage. However, there was a linear decreasing response for time spent resting (p &lt; 0.05). Time spent ruminating, number of boluses per day and numbers of chews per day per bolus were not affected (p &gt; 0.05) by the inclusion of castor bean meal. The addition of detoxified castor bean meal to sugarcane silage reduces time spent eating and increases feed and rumination efficiency in sheep.

title: Carcass characteristics of feedlot-finished Nellore heifers slaughtered at different weights

description: ABSTRACT. Carcass and meat characteristics of 48 Nellore heifers at 24 to 30 months of age, with an initial weight of 263.4 ± 13.9 kg, were evaluated. The experiment was set up as a completely randomized design with four treatments, which consisted of four slaughter-weight classes, namely &lt;340, 340-370, 370-400, or &gt;400 kg. Back fat thickness was not influenced (p &gt; 0.05) by slaughter weight in any of the forms it was expressed (mm or %), averaging 5.3 mm. Loin eye area in cm2 increased (p &lt; 0.05) with the increase in slaughter weight. Animals slaughtered at a live weight (LW) of more than 400 kg showed better (p &lt; 0.05) carcass conformation than the other experimental groups (9.8 points). Heifers slaughtered at over 400 kg LW had a more compact (p &lt; 0.05) carcass (1.65 cm kg-1 cold carcass). The marbling degree of meat was lower (p &lt; 0.05) in the animals slaughtered at less than 340 kg LW. In conclusion, cull heifers must not be slaughtered at a LW of less than 340 kg and slaughter weights greater than 400 kg have positive implications on important carcass characteristics, notably conformation and marbling.

title: Alternative construction and demolition (C&D) waste characterization method proposal

description: ABSTRACT Construction and demolition waste generally represents the majority of solid waste generated in Brazilian cities, and characterization of this waste stream is still incipient. Therefore, to support managers in the process in the diagnostic phase, this study consisted in a proposal qualitative characterization method in field, that use of construction and demolition (C&D) waste generation indicators. For this, a survey which have been divided in two stages: quantitative characterization based on a three-indicator-analysis of C&D waste generation and qualitative characterization consists of an image analysis procedure on C&D waste samples. The qualitative characterization method has proved to be efficient for samples with high-volume parts. However, this method is limited to represent characterizations that contain residues which might cover the other C&D waste types, for example, plastic sheeting, cardboard and packaging. This method of image analysis is suitable for use in early diagnostics, which require fast results about C&D waste composition.

title: CHEMOMETRIC TOOLS AND FTIR-ATR SPECTROSCOPY APPLIED IN MILK ADULTERATED WITH CHEESE WHEY

description: Brazilian law forbids the addition of cheese whey in milk. However, adulteration with cheese whey is one of the most applied fraud due to its low cost. The detection of this fraud is the quantification of Caseinomacropeptide (CMP). The CMP is a constituent of the whey that can be used as adulteration marker. Thus, an analytical method capable of identifying CMP by Fourier Transform Infrared Spectra (FTIR) was developed using chemometrics methods. Firstly, we attempted to develop an exploratory analysis model by Hierarchical Grouping Analysis (HCA) and Principal Component Analysis (PCA) that indicated similarity between samples of raw milk and semi-skimmed milk. Moreover, in the PCA scores, it was possible to observe a tendency of separation between samples with different concentrations of CMP. Afterwards, multivariate regression models were used for Partial Least Squares (PLS), Partial Least Square with Interval Synergism (siPLS) and Supporting Machines with Least Squares (LS-SVM) to quantify the adulteration in different types of milk by Cheese serum through the CMP. All the models were then compared to each other and the results of the official method with Liquid Chromatography Tandem mass spectrometry (LCMS/MS) analysis used by the Ministry of Livestock and Supply (MAPA). The model LS-SVM, employing the full spectrum, obtained the best result compared to the other models (PLS and siPLS) to quantify the CMP in the milk samples.

title: Influence seasons of the year and somatic cell counts on physical-chemical and sensory parameters of milk and coalho cheese

description: ABSTRACT. The objective of this study was to evaluate the influence seasons of the year and somatic cell counts (SCC) on physical-chemical and sensory parameters of cow’s milk from individual and collective refrigeration tanks with different milking systems. In addition to analyzing the sensory acceptance of pasteurized milk and coalho cheese developed with high (&gt; 800,000 cells mL-1) and low SCC levels (&lt;200,000 cells mL-1). Seasonality did not affect fat content, casein, lactose, total solids, defatted dry extract and SCC, but lower protein levels than May and June were observed from July to September. Based on the SCC results, milk from refrigeration tanks was classified as low SCC and high SCC. The samples were used to obtain pasteurized milk and coalho cheese which were sensorially evaluated for general appearance, odor and flavor by a panel of untrained tasters using a hedonic scale of 9 points. Pasteurized milk with high and low SCC presented pleasant sensory characteristics to the consumer up until two days of storage. The same behavior was observed for coalho cheese at 20 and 40 days of shelf life, respectively.

title: Tillering dynamics of digit grass subjected to different defoliation frequencies

description: Abstract: The objective of this work was to evaluate the tillering dynamics of 'Suvernola' digit grass (Digitaria eriantha) when subjected to different defoliation frequencies. Four defoliation frequencies (interval among harvests) were evaluated - very high, when the grass reached 25 cm in height; high, 35 cm; medium, 45 cm; and low, 55 cm - in two seasons of the year, with higher and lower insolation, from January 2015 to January 2016. A randomized complete block design with four replicates was used. The increase in defoliation frequency increased the number of generations and the appearance, mortality, and density rates of tillers, besides decreasing their survival rate, without changing population stability. At the time of lower insolation, tiller appearance and mortality rates were higher, while tiller survival rate, balance, and density were lower. The evaluated defoliation frequencies and seasons of the year do not change the persistence of digit grass when irrigated. Higher defoliation frequencies result in a greater renewal of digit grass tillers.

title: Delayed carcass chilling improves tenderness of the beef gluteus medius muscle

description: Abstract: The objective of this work was to evaluate the effects of a slower chilling rate on the physical traits of 14-day aged top sirloin (gluteus medius) from F1 Angus x Nellore young bulls. Slight and lean beef carcasses (n = 30) were split in half and selected for control (2°C for 24 hours) and treatment (10°C for 10 hours followed by 2°C for 14 hours). Carcass temperature and pH decline were monitored in the longissimus dorsi (LD). Sarcomere length, color, and instrumental tenderness (Warner-Bratzler shear force and Volodkevich bite jaws) were measured on the gluteus medius (GM). pH 6.0 was reached when the LD temperature was very low, 3°C for the control and 6°C for the treatment. Differences in color and cooking losses were not significant. A trend was noticed for shorter sarcomere length and greater Warner-Bratzler shear force in the GM control. However, a lower value for Volodkevich bite jaws was found in the GM subjected to the treatment. The cooling regimes adopted were not sufficiently different to cause changes in color traits; however, the slow chilling of carcass improved tenderness and can be a good alternative to produce high-value cuts.

title: Grazing height management does not change the persistence pathway of Andropogon lateralis in a natural pasture

description: Abstract: The objective of this work was to evaluate tiller dynamics and population stability of Andropogon lateralis in a natural pasture subjected to grazing height management under intermittent stocking method. The experiment was carried out in a randomized complete block design with four treatments and four replicates, in 16 experimental units of 875 m2 each. The treatments consisted of four pre-grazing heights of A. lateralis (12, 20, 28, and 36 cm), which was grazed until its initial height was reduced by 40%. Dynamics of tiller birth and death were evaluated using the marked tiller technique over a period of 18 months, from October 2015 to March 2017. The results indicate that the use of different heights for the management of natural pastures does not affect the stability of the tiller population of A. lateralis and that, regardless of the management strategy, the persistent pathway of this species is mainly based on the maintenance of high-tiller survival rates.

title: Management of medical waste in hospitals of Ribeirão Preto (SP), Brazil

description: ABSTRACT This research aimed to evaluate the management of medical waste in hospitals in Ribeirão Preto, São Paulo. This study is characterized as descriptive and exploratory, developed in 11 hospitals in the city. Data collection was carried out through interviews with the medical waste managers, analysis of their management plan and systematized observation. Data collection was initiated after hospital authorization, approval by the CEP of the Escola de Enfermagem de Ribeirão Preto, Universidade de São Paulo. The results revealed that the steps in handling medical waste such as identification, internal transportation, temporary storage, external collection and transport were classified as unsatisfactory, and only segregation was classified as satisfactory. Regarding the type of the treatment offered to medical waste, 7 (63.6%) managers reported that the residues of groups A and E were submitted to microwave treatment; and 5 (45.5%) showed that they did not know about the type of treatment given to group B waste. It is concluded that, despite the existence of a technical-legal framework regulating the guidelines for the managing medical waste, there were inadequacies related to its management.

title: Pain and Quality of Life in Human T-cell Lymphotropic Virus Type 1-Associated Myelopathy or Tropical Spastic Paraparesis After Home-Based Exercise Protocol: A Randomized Clinical Trial

description: Abstract INTRODUCTION: Human T-cell lymphotropic virus type 1-associated myelopathy or tropical spastic paraparesis (HAM/TSP) causes, among other abnormalities, chronic pain that may impair quality of life (QOL). Home protocols can help those who have difficulty attending rehabilitation centers. This study aimed to evaluate the impact of a home-based exercise protocol on pain and QOL in people with HAM/TSP. METHODS: A randomized clinical trial of people with HAM/TSP (World Health Organization criteria) classified as probable or definite. The supervised group (SG) underwent training for 12 weeks and continued the protocol at home for another 12 weeks; the unsupervised group (UG) performed the same protocol at home without physical therapist supervision for 24 weeks; and the control group (CG) maintained the usual care. QOL was assessed by the Short Form-36 health survey and the pain condition by the Brief Pain Inventory (BPI). The Chi-square, analysis of variance, Kruskal-Wallis, and Friedman tests (5% alpha) were used for the analyses. The intention-to-treat method was adopted in case of follow-up losses. Record number RBR-849jyv/UTN: U1111-1176-2858. RESULTS: Of 56 participants, 49 completed the protocol. Mean pain was moderately reduced (&gt;30%) in the UG and CG and mildly reduced (20%) in the SG. Loss in the vitality score of QOL in the CG was noted. CONCLUSIONS: The protocol generated mild and moderate pain relief and reduced losses in the functional QOL in the treatment groups.

title: Factors influencing the behavior of auctioneers operating in public procurement by Barreira do Inferno Launching Center (CLBI)

description: Abstract This article aims to analyze the preponderant factors influencing the behavior of auctioneers working for the Barreira do Inferno Launching Center (CLBI) in electronic purchasing processes. The research used references from the theory of purchasing, analyzing organizational and motivational aspects, as well as aspects related to knowledge and abilities. Data was collected using semi-structured interviews with auctioneers. As a result, it was possible to identify that the main factors influencing the auctioneer’s behavior at CLBI were the lack of recognition of the strategic importance of their role, lack of exclusive dedication and specialization.
