title: Further evidence for the existence of broiler chicken PFN (pale, firm, non-exudative) and PSE (pale, soft, exudative) meat in brazilian commercial flocks

description: Abstract This work aims to investigate the incidence of two color abnormalities in broiler meat: PFN (Pale, Firm, Non-exudative) and PSE (Pale, Soft, Exudative), as well as the physicochemical alterations promoted by those anomalies. The samples of broiler breast meat (n = 700) were classified as Normal (445.8), PSE (L*≥53, pH&lt;5.8) and PFN (L*≥53; pH&gt;5.8). The occurrence of Normal, PSE and PFN samples was 69%, 11% and 20%, respectively. PFN samples presented a 4.2% higher water-holding capacity compared to PSE meat. PSE meats displayed a higher MFI (89.4) when compared to PFN and Normal meats. It was also noticed that the levels of lipid oxidation were greater in PSE breasts compared to Normal breasts. The total carbonyl in PFN, Normal and PSE meats was 8.2, 7.4 and 5.7 nmol/mg proteins, respectively. These results confirm the existence of a PFN anomaly in broiler breast meat, which presents functional properties similar to the Normal group. In addition to that, the less firm texture displayed by PSE meats is the result of a greater proteolytic activity, which seems to be related not only to the activation of the calpains, due to the excessive Ca 2+, but also to the lower level of protein oxidation.

title: Manufacturing and Characterization of Jute/PP Thermoplastic Commingled Composite

description: The commingled technology is a promising technique for the manufacture of composites reinforced with natural fibers. This study presents the development, processing and basic characterization of a long fiber Jute/Polypropylene (Jute/PP) commingled composite. The Jute/PP fabric was produced in a handloom and the composite was consolidated by compression molding. The PP matrix was chemically and thermally characterized to certify its chemical composition and define its melting and crystallization temperatures. The degradation behavior of jute fibers was also studied by Friedman’s kinetic isoconversional model using thermogravimetric analyses (TGA). The mechanical properties of jute reinforcement and Jute/PP composite were characterized by tensile strength tests and by fractographic study of the fracture surfaces. Its tensile strength (44.62±6.02 MPa) and elasticity modulus (7.10±2.34 GPa) are approximate to the ones obtained by other processing techniques, suggesting that the developed commingled process can work as a low cost and practical alternative methodology for manufacturing of more sustainable composites in industries.

title: Characterization of Silica Produced from Rice Husk Ash: Comparison of Purification and Processing Methods

description: As a byproduct of the combustion of rice husk to generate energy, rice husk ash (RHA) is formed by silica and carbon, apart from small amounts of other constituents. Several treatments can be used to increase the purity of the silica obtained, or even produce pure silica. The present study tested the efficiency of different techniques to obtain silica, characterizing and comparing the silicas obtained from RHA. A literature review was conducted, and then selected techniques were used to produce silica, which was characterized by XRF, XRD, particle sizing, specific weight, specific surface area, total carbon, and SEM. The literature review showed that most techniques include a pretreatment like acid or alkaline leaching followed by thermal treatment to increase the amount of silica produced by reduction of carbonaceous materials. The results showed that it is possible to produce silica from RHA using simple methods, and that these produced silica with purity above 98%. The treatments that afforded the best results were acid leaching followed by thermal treatment at 800ºC, and alkaline extraction at low temperature, with silica purity of 99.3% and 99.6%, respectively.

title: Sweeteners and sweet taste enhancers in the food industry

description: Abstract The search for new sweeteners technologies has increased substantially in the past decades as the number of diseases related to the excessive consumption of sugar became a public health concern. Low carbohydrates diets help to reduce ingested calories and to maintain a healthy weight. Most natural and synthetic high potency non-caloric sweeteners, known to date, show limitations in taste quality and are generally used in combination due to their complementary flavor characteristics and physicochemical properties in order to minimize undesirable features. The challenge of the food manufacturers is to develop low or calorie-free products without compromising the real taste of sugar expected by consumers. With the discovery of the genes coding for the sweet taste receptor in humans, entirely new flavor ingredients were identified, which are tasteless on their own, but potentially enhance the taste of sugar. These small molecules known as positive allosteric modulators (PAMs) could be more effective than other reported taste enhancers at reducing calories in consumer products. PAMs could represent a breakthrough in the field of flavor development after the increase in the knowledge of safety profile in combination with sucrose in humans.

title: Association between molecular markers and behavioral phenotypes in the immatures of a butterfly

description: Abstract Newly hatched caterpillars of the butterfly Heliconius erato phyllis routinely cannibalize eggs. In a manifestation of kin recognition they cannibalize sibling eggs less frequently than unrelated eggs. Previous work has estimated the heritability of kin recognition in H. erato phyllis to lie between 14 and 48%. It has furthermore been shown that the inheritance of kin recognition is compatible with a quantitative model with a threshold. Here we present the results of a preliminary study, in which we tested for associations between behavioral kin recognition phenotypes and AFLP and SSR markers. We implemented two experimental approaches: (1) a cannibalism test using sibling eggs only, which allowed for only two behavioral outcomes (cannibal and non-cannibal), and (2) a cannibalism test using two sibling eggs and one unrelated egg, which allowed four outcomes [cannibal who does not recognize siblings, cannibal who recognizes siblings, “super-cannibal” (cannibal of both eggs), and “super non-cannibal” (does not cannibalize eggs at all)]. Single-marker analyses were performed using χ2 tests and logistic regression with null markers as covariates. Results of the χ2 tests identified 72 associations for experimental design 1 and 73 associations for design 2. Logistic regression analysis of the markers found to be significant in the χ2 test resulted in 20 associations for design 1 and 11 associations for design 2. Experiment 2 identified markers that were more frequently present or absent in cannibals who recognize siblings and super non-cannibals; i.e. in both phenotypes capable of kin recognition.

title: Dataset for: A noniterative sample size procedure for tests based on t distributions

description: A noniterative sample size procedure is proposed for a general hypothesis test based on the t distribution by modifying and extending Guenther’s (1981) approach for the one sample and two sample t tests. The generalized procedure is employed to determine the sample size for treatment comparisons using the analysis of covariance (ANCOVA) and the mixed effects model for repeated measures (MMRM) in randomized clinical trials. The sample size is calculated by adding a few simple correction terms to the sample size from the normal approximation to account for the nonnormality of the t statistic and lower order variance terms, which are functions of the covariates in the model. But it does not require specifying the covariate distribution. The noniterative procedure is suitable for superiority tests, noninferiority tests and a special case of the tests for equivalence or bioequivalence, and generally yields the exact or nearly exact sample size estimate after rounding to an integer. The method for calculating the exact power of the two sample t test with unequal variance in superiority trials is extended to equivalence trials. We also derive accurate power formulae for ANCOVA and MMRM, and the formula for ANCOVA is exact for normally distributed covariates. Numerical examples demonstrate the accuracy of the proposed methods particularly in small samples.
