title: Cold shortening decreases the tenderization of Biceps femoris muscle from lambs

description: SUMMARY This study evaluates the effects of Normal Shortening (NS) and Cold Shortening (CS) in sarcomere length, Warner-Bratzler shear force (WBS) and tenderization process examined by Myofibrillar Fragmentation Index (MFI). The Biceps femoris muscle from ten Dorper x Santa Inês lambs was randomly assigned to 1) NS = cooling of the muscle in the carcass for 24 hours in a cold room at 4°C; or 2) CS = rapid cooling, in ice bath, of the muscle removed from the carcass immediately after slaughter. Sarcomere Length (SL) was determined in the collected samples 24 hours after slaughter and WBS and MFI in the aging periods (1 or 10 days post-mortem). The WBS value of the meat for 1 and 10 days were greater (P&lt;0.05) for CS (4.90 ± 0.42 and 3.73 ± 0.42 kgf, respectively) than NS (4.07 ± 0.36 and 2.98 ± 0.38 kgf, respectively). There were negative correlations between WBS and SL (r= −0.59 and r=−0.69, P&lt; 0.05) at 1 and 10 postmortem, respectively. Furthermore, there were positive correlations for MFI and SL (r= 0.46 and r=0.48, P&lt; 0.05) at days 1 and 10, respectively. These results point to a negative impact of sarcomere cold shortening in the sheep meat tenderization process in the hindlimb muscle.

title: Application of the dictionary of activities to the food safety management system

description: Abstract Food has become a tourism product of high consumption thus requiring an appropriate food safety management system. Undoubtedly, the quality of the product is more important than the decoration, the service and even the prices. Food safety management has been implemented in many contexts, through the application of the HACCP system, but research on the topic focusing on the management of processes have been very scarce; hence, the objective of the present study is the application of the dictionary of activities to food safety management in a restaurant in the tourism destination of Varadero, Cuba. The importance of food safety for the customers justifies this study. Food safety and quality affect the consumers’ intention of return and their opinion about the tourism destination. This study draws on the methodology of Nogueira (2002) for the process improvement and on Trischler’s (1998) for the added value analysis. Different tools were applied like the survey, brainstorm, process map, AS-IS analysis, and process sheet. The study took place in a restaurant in the tourism destination of Varadero, Cuba, from January to May. The research revealed many activities that do not add value to food safety guarantee, and enabled to put forward three indicators to assist the restaurant management. It is concluded that the use of the dictionary of activities improved the food safety and quality management process. The dictionary allows the identification of the activities that add value to the safety management system, contributing to process effectiveness, and this is the main contribution of the research.

title: SOIL CHEMICAL ATTRIBUTES AND CORN PRODUCTIVITY GROWN ON LEGUME STUBBLE IN AGROFORESTRY SYSTEMS

description: ABSTRACT Leguminous species can improve nutrient cycling and chemical quality of Oxisols, resulting in higher productivity of intercropped crops. Thus, this research aimed to evaluate the decomposition rate and nutrient accumulation in legume stubble, as well as its contribution to soil chemical attributes, the growth of baru trees (Dipteryx alata Vogel), and yield of intercropped maize in an agroforestry system. The experiment was developed during the crop years of 2010-2011 and 2011-2012, in Goiás State, Brazil. The experimental design was a randomized block with five replicates. Leguminous species consisted of sunn hemp (Crotalaria juncea), jack bean (Canavalia ensiformis), pigeon pea (Cajanus cajan), Stylosanthes (Stylosanthes macrocephala - 20% and Stylosanthes capitata - 80%), and spontaneous vegetation (control treatment). The decomposition rates of legume and spontaneous vegetation residues remained unchanged in the agroforestry system. Sunn hemp, jack bean, and Stylosanthes plants are advantageous options for total accumulation of nutrients. However, sunn hemp grown as straw cover for next crop seasons increases the available phosphorus levels in the soil and productivity of maize cobs. With this coverage, maize productivity values were up to 24% higher than were those with maize growing on spontaneous vegetation, besides having no effect on the growth of baru trees.

title: GENETIC GAINS AND SELECTION ADVANCES OF THE UENF-14 POPCORN POPULATION

description: ABSTRACT Recurrent selection can generate successive gains for characters of economic interest without causing genetic narrowing in the population. However, it has rarely been used in breeding programs in popcorn, especially when using full-sibling progenies to generate more expressive gains. The objective of this study was to estimate the genetic gain of the UENF-14 popcorn population through recurrent selection, and verify the evolution of the gains between the selection cycles four and eight. A total of 200 full-sibling progenies were evaluated in randomized blocks arranged in eight sets within three replicates in two environments; each set containing twenty-five progenies and six controls (selection cycles 4, 5, 6 and 7 of the UENF-14, BRS-Angela and IAC-125). The average height, prolificacy, 100-grain weight, ear weight, grain yield, and grain popping expansion of the plants were evaluated. In the selection of the thirty superior progenies for the eighth cycle, the Mulamba and Mock selection index was used, which generated estimated genetic gains of 4.60 for grain yield and 3.61% for popping expansion. The grain yield increased 111.99 kg ha-1 and the popping expansion increased 1.75 mL g-1 per cycle. The evolution of the cycles resulted in an accumulated genetic gain for the main characters of economic importance, allowing the prediction of success in the continuity of the recurrent selection.

title: Comparison of In-Flight Measured and Computed Aeroelastic Damping: Modal Identification Procedures and Modeling Approaches

description: ABSTRACT The Operational Modal Analysis technique is a methodology very often applied for the identification of dynamic systems when the input signal is unknown. The applied methodology is based on a technique to estimate the Frequency Response Functions and extract the modal parameters using only the structural dynamic response data, without assuming the knowledge of the excitation forces. Such approach is an adequate way for measuring the aircraft aeroelastic response due to random input, like atmospheric turbulence. The in-flight structural response has been measured by accelerometers distributed along the aircraft wings, fuselage and empennages. The Enhanced Frequency Domain Decomposition technique was chosen to identify the airframe dynamic parameters. This technique is based on the hypothesis that the system is randomly excited with a broadband spectrum with almost constant power spectral density. The system identification procedure is based on the Single Value Decomposition of the power spectral densities of system output signals, estimated by the usual Fast Fourier Transform method. This procedure has been applied to different flight conditions to evaluate the modal parameters and the aeroelastic stability trends of the airframe under investigation. The experimental results obtained by this methodology were compared with the predicted results supplied by aeroelastic numerical models in order to check the consistency of the proposed output-only methodology. The objective of this paper is to compare in-flight measured aeroelastic damping against the corresponding parameters computed from numerical aeroelastic models. Different aerodynamic modeling approaches should be investigated such as the use of source panel body models, cruciform and flat plate projection. As a result of this investigation it is expected the choice of the better aeroelastic modeling and Operational Modal Analysis techniques to be included in a standard aeroelastic certification process.

title: Daily water demand

description: Abstract This paper develops a model to characterize the demand for domestic water based on its end users' usage habits. The use of individual residential appliances (bathroom sink, toilet, shower, bath, etc.) is interpreted using a probabilistic approach. The paper also applies the model to the distribution network of the municipality of Sparanise, a small city in the province of Caserta, Italy. The results of this application are compared to the real output of the city's actual water reservoir. Flow variability during the day was successfully modelled. A comparison of the simulated and recorded data on a daily level indicates the proper adjustment of the volume distribution; the peak flow rates were also comparable. The model could be a useful tool for analyzing domestic water consumption, especially in the design and management of water distribution networks. Use of the model would particularly aid the Integrated Urban Water Management Operator both in optimizing the operating pressures in the various districts’ networks and in predicting domestic water consumption when drafting its water balance documents.

title: Vulnerability and climate change: socio-environmental analysis in a mesoregion of Amazonia

description: Abstract The study of socio-environmental vulnerability associated with climate change is one of the topics most discussed by the international scientific community. The effects of climate change on society stem from different causes and effects; their analysis must take into account the cultural, economic and social context of a population. Thus, studies involving risks associated with extreme weather events must be done in an integrated and interdisciplinary way. In this context, the present research aims to contribute to vulnerability analysis in the metropolitan mesoregion of Belém, with a view to reducing the effects caused by climate and social changes. In order to do so, the General Vulnerability Index (GVI) was applied, based on socioeconomic, epidemiological and climatic indicators from 2000 to 2010. The results found that the municipality of Belém had the highest value of GVI (0. 61), indicating a high vulnerability, presenting the highest indexes of climatic (1.00) and epidemiological (0.76) vulnerability. On the other hand, the municipality of Bujaru has a low vulnerability, with a GVI value of 0.14, explained by the minimum value of the index of climate vulnerability (0.00) and low indices of epidemiological (0.03) and socioeconomic vulnerability (0.38). We expect that this study may support the management of public policies for the municipalities and encourage studies of socio-environmental vulnerability in the Amazon region, with an interdisciplinary approach.

title: Diversity Indexes Performance in the Tree-lined Street Composition

description: ABSTRACT In this research was analyzed the performance of diversity indexes facing different scenarios of composition with distinct species richness and uniformity, the influence of planting spacing in the determination of values of these indexes and the behavior of diversity data of a street tree inventory in relation to two scenarios of composition approximated to real data. It was noted that there is significant influence of increased planting spacing only for species richness indexes. There was significant differences between values of all indexes for the diversity scenarios elaborated. In the scenarios analyzed, the species richness indexes showed lower and more stable values than inventory ones and the evenness indexes showed higher values.
