title: Microclimate and thermal comfort indices in silvopastoral systems under different planting directions and seasons

description: ABSTRACT The orientation of tree-rows in a silvopastoral system associated with different seasons of the year allows more or less sunlight penetration, resulting in deliberate modification of the microclimate composition and thermal conditions provided to animals. In this sense, the aims of this study were to evaluate microclimatic variables and thermal comfort indices for east-west and north-south oriented silvopastoral systems, compared to unshaded systems during summer and winter. The study was conducted at the Modelo II Farm (21° 08’ S 53° 17’ W) at an altitude of 354 m. A randomized block design in scheme of split-split plots with five repetitions was adopted. Two planting directions and a control treatment (unshaded) were evaluated in the plots. Collection times were evaluated in sub-plots, and the distance from eucalyptus trees was evaluated in sub-sub-plots. Changes in the east-west and north-south planting directions did not promote changes in climate variables, nor did they change the thermal comfort indices during summer. There were differences, however, in temperature and relative humidity of the air, black globe temperature, and radiant heat load during winter. Silvopastoral systems provide improvements in the environment and, concomitantly, to the thermal comfort of animals, when compared to unshaded systems. However, thermal stress situations occur despite the presence of trees, depending on the time of the day and the distance from the rows of eucalyptus trees.

title: Fortified and freeze-dried kiwi fruit (Actinidia deliciosa): quality and sensory assessment

description: Abstract Kiwi fruit (Actinidia deliciosa) (KF) is one of the best fruits available due to its large amount of nutrients. Despite its many health benefits, there are no previous reports on its preparation in other readily ingestible forms. The objective of the present study was to make a new food product from KF. The KF pulp was fortified and blended with several raw materials (such as rice flour and oat flour) using a stepwise short time addition and mixing methodology since this avoids unwanted biochemical and chemical reactions. The blended and reduced moisture KF paste was freeze-dried on a round silver coated steel plate (RSCSP), supplying the heat of sublimation using a newly designed cubic heater. The freeze-drying (FD) time was 4.5 h and the drying kinetics were studied using four established models. The effective moisture diffusivity (Deff) during FD (at 50 °C) was 1.532 x 10-6 m2/s and the activation energy (E) estimated for the FD was 28.35 kJ/mol. The freeze-dried sample was ground and placed under vacuum to reduce the weathering effects. The quality of the stored product was evaluated using the proximate analysis, physicochemical analysis and a sensory evaluation using a hedonic scale. The raw, fresh KF had a moisture content of 85.07% and the final freeze-dried product one of 3%. The carbohydrate, total sugar, protein, fat, total ash, crude fibre and vitamin C contents of the final product increased by 563%, 400%, 355%, 386%, 672%, 106%, and 117% respectively. Of the 66 panelists, the % consumer acceptances for the different attributes were: sweetness (68.18%), sourness (90.91%), saltiness (100%), bitterness (100%), flavour (95.45%), texture (77.27%) and overall acceptability (81.82%). Using conventional freeze-drying (CFD) for blended KF pulp without fortification, with the same RSCSP and the same cubic heater for sublimation, the drying time was found to be 7 h to reach the same final moisture content of 3%.

title: Quality of ‘Royal Gala’ cut apple during osmotic dehydration

description: Abstract The present work aimed to evaluate quality parameters of ‘Royal Gala’ apple cubes during osmotic dehydration (OD). We investigated the following OD conditions: osmotic agent, pressure, and temperature. The osmotic agent, being lower after OD with sorbitol than sucrose solutions, mainly influenced the water activity of the product. The color changes increased with increased temperature and were higher in vacuum experiments than at atmospheric pressure. In general, we recommend OD at 25 °C and atmospheric pressure for the preservation of the total phenolic content (TPC) and antioxidant activity (AA) of apple cubes during the process. Peleg’s model was found to provide the best fit of TPC and AA data.

title: Food losses and waste: reflections on the current brazilian scenario

description: Abstract Globally, the world’s population increases more than eighty million people each year, and Brazil is one of the world’s most populous countries. To ensure the survival of humankind on Earth we need to review attitudes related to the use of natural resources, which directly affect the availability of food and other basic needs. In this context, this study aims to evaluate the relationship between human’s rights to food with food waste and loss. Bioethical and legal aspects will be evaluated, as well as environmental, economic and social factors. In addition, we will verify initiatives that are happening towards the improvement of this subject in Brazil, and the proposals related to individualized actions. Brazil is one of the countries that most wastes food in the world and there are several factors that contribute to this scenario, such as legal barriers that could facilitate the donation of expired food or those considered out of consumption standards, thereby reducing the generation of organic residues.

title: Leg myxoid liposarcoma: correlation between image and anatomopathological tests

description: ABSTRACT A 41-year-old male patient refers to a painful tumor on the lateral side of the right leg. Ultrasonography visualized a predominantly hypoechoic well-delineated large heterogeneous mass in the subcutaneous tissue, showing an internal hyperechoic area. Magnetic resonance imaging (MRI) demonstrated an oval and lobulated tumor with well-defined margins at the anterolateral part of the leg, with contrast enhancement. The anatomopathological evaluation revealed a neoplasm with an extensive chondromyxoid matrix. The immunohistochemical study demonstrated positive vimentin (V9 clone), positive S-100 protein and negative desmin (D33 clone), smooth muscle actin (1A4), CD68 (KP1 clone) and caldesmon. The set of findings is compatible with myxoid liposarcoma.

title: Thrombogram: case report of pseudothrombocytopenia

description: ABSTRACT The thrombogram is one of the components of the blood count that includes platelet quantification and evaluation. The presence of laboratory artifacts, such as incorrect platelet counts by autoanalyzers, can lead to pseudothrombocytopenia, which is responsible for 15% to 30% of the cases of isolated thrombocytopenia observed in laboratory routine. Pseudothrombocytopenia induced by the anticoagulant ethylenediaminetetraacetic acid (EDTA) is one of the most frequent cases in which the presence of anticoagulant in blood samples can cause platelet aggregation or platelet satellitism. Careful observation of the data emitted by autoanalyzers, such as platelet and flag histograms, is crucial. Other procedures, such as checking for clotting in the sample, repeating the sample and viewing a peripheral blood smear, requesting a new sample taken with another type of anticoagulant, such as citrate, are imperative for the confirmation of cases of pseudothrombocytopenia.

title: Efficiency of a brackish water desalination pilot system

description: ABSTRACT Considering the shortage of fresh water availability and an increased demand for water in the world, including Brazil, one of the alternatives for water supply are water desalination systems, which remove salts from brackish or seawater. The objective of this study was to evaluate the efficiency of pilot water desalination system treating brackish water which was obtained mixing fresh water and seawater up to reach 1,500 mg L-1 of total dissolved solids (TDS) concentration. The pilot desalination plant with production capacity of 1.0 m3 h-1 is composed of ultrafiltration (UF) and softener working as a pre-treatment to reverse osmosis (RO). Experiments were performed to analyze some water quality parameters as TDS, electrical conductivity, turbidity, pH, apparent color, alkalinity, total hardness, calcium, magnesium, chlorides, sulfates, and temperature. Osmotic pressure, filtration flow and water recovery rate were also measured for the RO. Analyzing the result obtained, it can be concluded that the efficiency of TDS removal and conductivity were 99%. UF was efficient in removing turbidity, whereas RO reached higher salt removal efficiencies. The pilot plant system could remove all water quality parameters studied. Recovery rate in RO was 74.64%.

title: Lyophilized and microencapsulated extracts of grape pomace from winemaking industry to prevent lipid oxidation in chicken pâté

description: Abstract The aim of this study was to characterize spray-dried and lyophilized powders made from winery by-products and to evaluate their effect on the oxidative stability of chicken pâté. Phenolic profile, antioxidant activity, and microencapsulation efficiency were evaluated in the extracts. Two pâté formulations containing grape pomace lyophilized (GPWL) and grape pomace microencapsulated (GPWM) were produced. In addition, a sodium erythorbate and a control batch were used to compare the effects. The pâtés were evaluated by thiobarbituric acid reactive substances (TBARS) assay during refrigerated storage (4 °C/42 days). Although the microencapsulation efficiency was 90.03%, the GPWL was statistically more effective in the lipid oxidation inhibition in chicken pâté than GPWM. However, the addition of both natural antioxidants in chicken pâté resulted in lower TBARS values than pâté treated with synthetic antioxidant due to the presence of gallic acid, caffeic acid, vanillic acid, ferulic acid, coumaric acid and trans-resveratrol with high antioxidant activity. Thus, the bioactive compounds with antioxidant activity detected in the GPWL and GPWM opened possibilities for use as a potential ingredient in chicken pâté and other meat products.

title: Rabies in Callithrix sp. in the urban area of Niterói, Rio de Janeiro, Brazil

description: Abstract In Brazil, rabies occurs mainly within an urban cycle, in which dogs and bats are reservoirs. This paper aims to report the occurrence of rabies in Callithrix sp. in Niterói, Rio de Janeiro, Brazil. In June 2019 a hybrid specimen was referred for diagnosis. The Direct Fluorescent Antibody, Mouse Inoculation, and Polymerase Chain Reaction tests were positive. A phylogenetic analysis was compatible with antigenic variant 3, characteristic of Desmodus rotundus. New studies should be undertaken to elucidate the real role of callitrichids in the urban rabies cycle.

title: Gamma ray attenuation for determining soil density: laboratory experiments for Environmental Physics and Engineering courses

description: Abstract In this paper, we present in details a method for determining the soil density of disturbed samples. The mass attenuation coefficient was also evaluated by using the relation between the number of photon counts and the path length (soil density \texttimes thickness). A typical student laboratory setup (PASCO) was utilized in the measurements. A gamma ray source of 137 Cs and soils with four different textural classes were employed. The experimental apparatus here proposed, that uses an educational gamma ray attenuation system, permitted measuring, with very good agreement with the traditional method, the density of soil samples. The experiment can be somehow extended by proposing the investigation of soil bulk variations due, for instance, to soil compaction, a subject of interest for engineering and environmental physics students.

title: ABSORPTIVE CAPACITY IN ANALYTICS IMPLEMENTATIONS: A RESEARCH MODEL

description: ABSTRACT Purpose: Propose a research model that involves the conceptual relationships between the theoretical support of the absorptive capacity and analytics, emphasizing the way in which the tool contributes to the formation of absorptive capacity within the companies. Originality/value: It was possible to delineate a model with the theoretical associations between absorptive capacity and analytics from the voices of experts and decision makers of Portuguese companies, contributing as a tool to guide strategies that help companies for a better understanding of how the absorption of knowledge occurs in analytics implementations to better target efforts at incremental value generation. Design/methodology/approach: A qualitative study was carried out with the adoption of Grounded Theory as a research strategy. In this way, techniques and procedures of the method were followed that allowed the constant collection and analysis of the data, supported with the use of Atlas.ti software. Findings: The main theoretical contribution is the proposition of a conceptual model that considers emerging categories, subcategories, properties, and dimensions, that qualify the conceptual alignment between absorptive capacity and analytics and explain the existence of the construct over implementation. As entrepreneurial contributions, the configuration of knowledge absorption according to two analytic use patterns is emphasized: as oriented towards solving specific problems and as a guideline of institutional planning.
