The aim of this study was to measure the influence of egg-laying hen manure, used in different rates, as topdressing fertilizer on corn yield and silage quality. The corn, variety UFVM-100 Nativo, was used. The experiment consisted of a randomized block design with six treatments (0.00, 0.75, 1.50, 2.25, 3.00, and 3.75 t ha-1 of tanned manure) and four replications. We measured the plant height, point of ear insertion, stem diameter, prolificacy, ear weight, proportion of ears in green matter, and the productivity of green and dry biomass of plants. After the harvest, the material was ensiled. After 64 days of storage, the silos were opened to determine the dry biomass, crude protein, losses by gases and by effluent, loss of total dry biomass, and dry biomass recovery of silages. Data were subjected to analysis of variance by the F test and the means analyzed through regression analysis. There was a linear increase in productivity of green and dry biomass of corn plants in response to manure application. The other agronomic characteristics and quality of silage did not show significant difference among treatments. The application of 3.75 t ha-1 hen manure is recommended to reach higher production of green and dry biomass of corn plants for silage. The organic fertilization with hen manure does not affect quality of the produced silage.

Knowledge on the water sorption within agricultural products is extremely important for decision making during post-harvest procedures. In order to improve this knowledge, thermodynamic properties regarding water sorption provide useful data. Thermodynamic properties of castor beans, related to sorption, were determined. Static gravimetric technique under different conditions of temperature (25, 35, 45 and 55 ± 1 °C) was used. Saturated salt solutions in the range of 37-87% ± 2% were utilized to create the required controlled humidity environment. After the sorption procedure, differential enthalpy, differential entropy and Gibbs free energy of this process were calculated and decreased with increased values of equilibrium moisture content. © 2016, Departamento de Engenharia Agricola - UFCG/Cnpq.

Sorption isotherms are of great importance in post-harvest procedures, especially for predicting drying and storage, which help to establish the final moisture content of the product under certain environmental condition. Hysteresis is a phenomenon that occurs due to the difference between adsorption and desorption curves, which aids the evaluation of chemical and microbiological deteriorations, indicating the stability of stored products. Moisture sorption isotherms of castor beans were determined and hysteresis was analyzed. Static gravimetric technique at different temperatures (25, 35, 45 and 55 ± 1 °C) was used. Saturated salt solutions in the range of 37-87% ± 2% were utilized to create the required controlled relative humidity environment. Equilibrium moisture content data were correlated by different mathematical models and the Modified Halsey model presented good adjustment for the data, according to statistical procedures. Hysteresis between adsorption and desorption isotherms is present over the range of 0.2-0.9 of water activity, regardless of the temperature. This phenomenon decreases with temperature increase. © 2016, Departamento de Engenharia Agricola - UFCG/Cnpq. All rights reserved.

The purpose of this work was to evaluate texture alterations due to compression load on tomatoes stored at 15 and 25C, which simulates transport in type "K" wooden boxes. The following mechanical properties were analyzed during storage: firmness, proportional deformity modulus, energy to deform the product, penetration force of the tomato skin and the energy required for penetration. Structural alterations were noticed solely by a puncture test. The mechanical property values significantly decreased during storage. The weight loss varied significantly among control and treatment tomatoes during storage, and the tomatoes stored at 25C obtained higher weight loss values. These results will aid in generating logistic procedures to prevent mechanical damage to tomatoes when they are transported in wooden boxes, thus increasing producer profitability. Furthermore, if damage to tomatoes does occur, professionals will be able to predict the shelf life of the tomatoes. © 2015 Wiley Periodicals, Inc.

The practice of refrigerating raw milk at the farm has provided a selective advantage for psychrotrophic bacteria that produce heat-stable proteases and lipases causing severe quality problems to the dairy industry. In this work, a protease (AprX) and a lipase (LipM) produced by Pseudomonas fluorescens 041, a highly proteolytic and lipolytic strain isolated from raw milk obtained from a Brazilian farm, have been purified and characterized. Both enzymes were purified as recombinant proteins from Escherichia coli . The AprX metalloprotease exhibited activity in a broad temperature range, including refrigeration, with a maximum activity at 37 C. It was active in a pH range of 4.0 to 9.0. This protease had maximum activity with the substrates casein and gelatin in the presence of Ca (+2) . The LipM lipase had a maximum activity at 25 C and a broad pH optimum ranging from 7.0 to 10. It exhibited the highest activity, in the presence of Ca (+2) , on substrates with long-chain fatty acid residues. These results confirm the spoilage potential of strain 041 in milk due to, at least in part, these two enzymes. The work highlights the importance of studies of this kind with strains isolated in Brazil, which has a recent history on the implementation of the cold chain at the dairy farm.

The objective was to evaluate the performance, quantitative and qualitative characteristics of carcases of male pigs surgically castrated and immunocastrated in finishing phase. Thirty - two crossbred animals (Landrace and Large White) with average initial weight of 92 kg were used, wich 16 males surgically castrated and 16 males immunocastrated. The animals were distributed in a randomized complete block design with two treatments, surgically castrated males or immunocastrated males, with eight replicates and two animals per experimental unit. There was no difference (P > 0.05) in the daily feed intake between castrated and immunocastrated animals. However, there was an increase (P = 0.05) in the daily gain weight of the immunocastrated males in relation to surgically castrated. It was also observed that immunocastrated pigs obtained a lower fat thickness in relation to surgically castrated pigs (P < 0.05). The castration form did not influence other carcass characteristics. The qualitative characteristics were not influenced (P > 0.05) by the castration method. It is concluded that immunocastration increases the daily weight gain, reduce the backfat thickness and does not affect the qualitative characteristics of carcasses.

The objective of this study was to evaluate the possible correlations between the socioeconomic development indicators of the municipalities of Minas Gerais, Brazil, and the presence of both sustainable use and full protection conservation areas (CAs). The Human Development Index (HDI) and Gini Index (GI) values were compared between municipalities with and without CAs using the non-parametric Wilcoxon-Mann-Whitney test. The correlations between the HDI and GI of each municipality and its areas occupied by CAs were analyzed using the non-parametric Spearman correlation test. A total of 560 CAs were identified in the 853 municipalities of the state. The HDI values of municipalities with CAs were not significantly different from those of other areas, but significant differences were found in the GI values, which were higher in municipalities with CAs. No significant correlations were found between the HDI of municipalities and their areas occupied by CAs. However, significant correlations were found between the GI and areas occupied by CAs, suggesting that the CAs are associated with greater socioeconomic inequalities. Populations should be included in conservation efforts through programs that benefit these individuals, such as payment for environmental services and other conservation strategies. © 2016, all rights reserved.

Currently the opportune diagnosis of cancer has shown a great importance, mainly by decreasing the mortality rate. Among the techniques employed to achieve the diagnosis, spectroscopy has been highlighted for presenting safe and highly accurate diagnoses. The Fluorescence Spectroscopy has become very important in cancer diagnosis, being employed in breast, oral cavity and esophagus cancer testing. The technique employs fluorophore which in many cases have groups capable of carrying out the intramolecular proton transfer in the excited state (ESIPT). These compounds may be used for various molecular targets such as cations, anions and proteins detection, besides the diagnosis of diseases. Spectroscopic probes have an important role in the development of more accurate diagnosing diseases methods, which may influence the treatment and avoid the risks of further surgery and patient death.

The use of commercial softwares for the management of dairy cattle has become increasingly common and therefore this study aimed to analyze the methodologies theese softwares uses to calculate the cost of production. Five software development companies agreed to participate in the study. Data from the same farmer were registered in each software to allow standardized tests for identification of structuring costs items and enable the analysis and identification of the methodologies used. The softwares that had all structuring costs items, highlighting the records of inventory, depreciation and opportunity costs, correctly applied the methodology of the total cost of production and the software that implemented the methodology of operational cost of production didn´t showed structuring costs items, inventory and depreciation, necessary for the correctly application of that methodology. © 2015, Universidade Federal Rural de Pernambuco.

Provenance generated by different workflow systems is generally expressed using different formats. This is not an issue when scientists analyze provenance graphs in isolation, or when they use the same workflow system. However, when analyzing heterogeneous provenance graphs from multiple systems poses a challenge. To address this problem we adopt ProvONE as an integration model, and show how different provenance databases can be converted to a global ProvONE schema. Scientists can then query this integrated database, exploring and linking provenance across several different workflows that may represent different implementations of the same experiment. To illustrate the feasibility of our approach, we developed conceptual mappings between the provenance databases of two workflow systems (e-Science Central and SciCumulus). We provide cartridges that implement these mappings and generate an integrated provenance database expressed as Prolog facts. To demonstrate its usage, we have developed Prolog rules that enable scientists to query the integrated database. © Springer International Publishing Switzerland 2016.
