title: Prediction of soil CO2 flux in sugarcane management systems using the Random Forest approach

description: ABSTRACT: The Random Forest algorithm is a data mining technique used for classifying attributes in order of importance to explain the variation in an attribute-target, as soil CO2 flux. This study aimed to identify prediction of soil CO2 flux variables in management systems of sugarcane through the machine-learning algorithm called Random Forest. Two different management areas of sugarcane in the state of São Paulo, Brazil, were selected: burned and green. In each area, we assembled a sampling grid with 81 georeferenced points to assess soil CO2 flux through automated portable soil gas chamber with measuring spectroscopy in the infrared during the dry season of 2011 and the rainy season of 2012. In addition, we sampled the soil to evaluate physical, chemical, and microbiological attributes. For data interpretation, we used the Random Forest algorithm, based on the combination of predicted decision trees (machine learning algorithms) in which every tree depends on the values of a random vector sampled independently with the same distribution to all the trees of the forest. The results indicated that clay content in the soil was the most important attribute to explain the CO2 flux in the areas studied during the evaluated period. The use of the Random Forest algorithm originated a model with a good fit (R2 = 0.80) for predicted and observed values.

title: Crossbreeding locally adapted hair sheep to improve productivity and meat quality

description: ABSTRACT: The use of lambs from crossing of local with specialized sheep breeds for meat production may lead to higher meat deposition and a smaller fat amount in the carcass, with a more adequate nutritional profile for human consumption. This study investigated the performance, carcass and meat characteristics of lambs from the Morada Nova and Santa Inês locally adapted hair breeds and crosses between Dorper × Morada Nova and Dorper × Santa Inês slaughtered at approximately 35 kg. Morada Nova lambs showed lower (p &lt; 0.05) performance compared to the other genetic groups resulting in a higher age at slaughter (p &lt; 0.05). Crossbred Dorper × Santa Inês and Dorper × Morada Nova lambs showed better characteristics for meat production with better (p &lt; 0.05) conformation as well as leg and carcass compacteness index. Dorper × Santa Inês have a fatty acid profile that is more suitable for human consumption than Dorper × Morada Nova lambs do (p &lt; 0.05); however, both had lower (p &lt; 0.05) intramuscular lipid content (as measured by ether extract levels from Longíssimus lumborum) compared with purebred lambs. Therefore, when the objective is to obtain lean meat, with improved nutritional profile to reduce risks of cardiovascular disease, the use of breeds and crosses that reduce animal slaughter age, such as the ½ Dorper × ½ Santa Inês crossbred, is an interesting alternative.

title: A program of physical activity improves gait impairment in people with Alzheimer's disease

description: Abstract AIM This study aimed to identify the effects of aging and Alzheimer’s disease (AD) on gait parameters after a four-month period and to investigate the effects of a four-month program of physical activity, with emphasis on the cognitive components of gait during single and dual task, in people with AD. METHODS Twenty-three people with AD, divided into the Training Group (TG; n=12; aged 79.17±7.62 years) and the Control Group (CG; n=11; aged 77.00±5.57 years), and eleven healthy older adults (Healthy Group - HG; aged 75.82±4.83 years) were included in this study. TG participated in a physical activity program for four months. The CG and HG were instructed not to participate in any kind of regular physical activity in this period. The physical activity program includes motor activities and cognitive tasks simultaneously. The participants attended a 1-h session three times a week. The kinematic parameters of gait were analyzed under two conditions, before and after a physical activity program: single and dual task. Deltas for all dependent variables between pre and post training were calculated. The deltas were compared using two-way ANOVAs with group (TG x CG and CG x HG) and task (single x dual task) as factors, with repeated measures for task. RESULTS After the training period, the TG improved stride length, duration, velocity and cadence compared to the CG. CONCLUSION Physical activity with emphasis on cognitive components promotes better reallocation of attention while walking in people with AD, improving attentional focus on the gait and thus resulting in a safer locomotive pattern.

title: Influence of drying process on total phenolics, antioxidative activity and selected physical properties of edible bolete (Phlebopus colossus (R. Heim) Singer) and changes during storage

description: Abstract The research aimed to study the effect of hot-air drying on the properties of edible bolete mushroom (Phlebopus colossus (R. Heim) Singer). Fresh edible bolete contained an efficient antioxidant activity, showing a significant value of total phenolic content and radical scavenging activity and was high in protein and fiber with low fat content. The changes in physicochemical and antioxidative properties of edible bolete during hot-air drying at various temperature and time were studied. The phenolic content and antioxidative properties of edible bolete decreased with the temperature and drying time. At 60 °C for 5 h, the phenolic content and antioxidative properties of the dried edible bolete remained at 25% compared to the fresh mushroom. Moreover, there was no substantive change in the bacterial count of dried edible bolete with vacuum packing after six months at room temperature.

title: Effect of modified cassava starch on the rheological and quality properties of a dairy beverage prepared with sweet whey

description: Abstract The effect of sweet whey and octenyl succinic anhydride (OSA)-modified cassava starch on the quality and rheological properties of fermented dairy beverages was evaluated. Sweet whey (45-65%) and OSA-modified cassava starch (0.8-1.2%) were added to determine an optimal fermented dairy beverage with the highest viscosity and the lowest syneresis possible. The optimal fermented dairy beverage corresponded to the addition of 40.9% sweet whey and 1.13% OSA-modified cassava starch with respect to the milk and sweet whey mixture. Moreover, the rheological and quality properties of the optimal fermented dairy beverage were compared to a commercial beverage (control) during 22 days of storage. No significant differences were found in soluble solids, acidity, pH and consistency index during the time evaluated, while the syneresis of both products showed an increase during storage. OSA-modified cassava starch can be used as a stabiliser in sweet whey fermented dairy beverages because it helps improve its quality properties.

title: Sheep meat commercialization in the retail market in Brazilian cities

description: ABSTRACT This paper explored the mix market characteristics of sheep meat as a product for sale in different cities in the states of São Paulo and Paraná. For this, 81 products were purchased in 21 outlets sampled in a “non-probabilistic” manner for convenience and then subjected to analysis of yield of meat, bone, and fat. Imported products represented 20% of the total, being marketed in hypermarkets. It was observed that 37% of the total products were obtained in hypermarkets, 31% in supermarkets, 23% in butcher shops, and 8.6% in meat outlets. Almost 9% of the products had not undergone the official slaughter inspection system. The main types of products identified were palettes and legs with bones (33.3 and 24.7%, respectively); however, only 25% were satisfactorily displayed to consumers. The yields obtained in meat and deboned portions were 74% and 59% of the total weight, significantly affecting the average adjusted sales prices of the products, respectively US$13.01/kg sale price; US$17.82/kg deboned; and US$22.52/kg lean meat. The low yield of clean and boned meat observed in the samples can lead to negative experiences of these products by consumers.

title: Peel and pulp of baru (Dipteryx Alata Vog.) provide high fiber, phenolic content and antioxidant capacity

description: Abstract Baru (Dipteryx alata Vog.) is a native fruit of the Brazilian Savannah that can be used in the food industry and may contribute to the economy of the Brazilian Midwest. The proximate composition, the phenolic content and the antioxidant capacity of the peel, pulp and raw and roasted baru almond were examined and compared. Peel showed higher concentrations of dietary fibers (24.1 g/100 g) followed by pulp and roasted almond (18 g/100 g and 16 g/100 g, respectively), and raw almond (12.0 g/100 g). However, the almonds presented the highest lipid and protein concentrations compared to baru peel and pulp. In addition, raw almond showed the highest total phenolic contents (1,107.0 mg GAE/100 g) and antioxidant capacity, but the roasted almond, and baru peel with its pulp, also presented high phenolic contents. The correlation coefficients between phenolic content and antioxidant capacity (via ABTS and FRAP) were strong and significant. The chemical composition of baru peel has not previously been reported. The results showed promising prospects for the consumption of baru pulp with its peel, the fruit component richest in fiber, whose phenolic content and antioxidant capacity are comparable to those of the baru almond.

title: Partial replacement of wheat flour by pumpkin seed flour in the production of cupcakes filled with carob

description: Abstract Pumpkin seeds are considered waste and its composition has high protein content, being feasible for human consumption, also reducing costs in waste treatment. In this work we provided an alternative to reuse the wastes of pumpkin seed applied in cupcakes formulation as a complementary source to wheat flour. Four formulations with different proportions of pumpkin seed flour were investigated. The effects of partial wheat flour substitution were evaluated using the parameters texture, height, diameter, specific volume, color, proximate composition and scanning electron microscopy. The formulations used in this work consisted of a control, prepared with wheat flour and three provided of 25%, 50% and 75% of pumpkins seed flour in partial in partial replacement to wheat flour. The incorporation of pumpkin seed flour influenced products significantly (p &lt;0.05), providing greater texture, cohesion, pH, soluble solids (Brix). According to results, the formulation with 50% pumpkin seed flour was considered the best proportion due to similarities with the formulation of 100% wheat flour besides high protein.

title: Hematological and biochemical characteristics during the transport of dog snapper Lutjanus jocu (Perciformes: Lutjanidae)

description: ABSTRACT The objective of this study was to evaluate stress responses in dog snapper (Lutjanus jocu) during transport by evaluating their hematological and biochemical responses. Twenty-five wild dog snapper specimens were used in the experiment (220 ± 68 g and 24.5 ± 2.5 cm total length). Blood samples were collected prior to transport (control), and fish were placed in two transport boxes, one with anesthetic and one without anesthetic. Immediately after transport and after 24 h, blood was collected from the fish that underwent each treatment (with anesthetic and without anesthetic). Biochemical and hematological results demonstrated the inefficiency of benzocaine as a stress reliever during handling and transport. Biochemical parameters revealed the effects of stress during transport, and after 24 h, glucose levels and hematological parameters (hemoglobin, erythrocytes, leukocytes, neutrophils and MCH) showed a tendency to return to control levels. This study is the first to report stress response measurements of hematological and biochemical indicators in dog snapper, representing an important basis for the planning of future experiments involving the transport and handling of this fish species.
