Abstract: the objective of this study was to estimate tissue composition of the carcass from physical composition of commercial cuts of f1 crossbred goats (boer with females of non-defined racial standard) finished on native pasture with four levels of supplementation with concentrate (0.0; 0.5; 1.0 and 1.5% of bw in dry matter). it was used 24 non-castrated animals at initial body weight of 15.52 kg and at 120 days of age. the carcass was sectioned in the half, and from the lefthalf carcass, the following cuts were detached: leg, loin, ribs, shoulder and neck, which were dissected in muscle, bone and fat. carcass weight and yield were predicted from the weight and yield of tissues in the commercial cuts by regression analysis. all the cuts can be used to predict muscle and fat weight in the carcass. for the muscle, the relationship was linear and positive in the cuts leg, ribs, shoulder and neck, and cubic in the loin; for all the cuts, fat kept a linear relationship with the carcass. muscle and fat yield of all the commercial cuts showed a positive linear relationship with carcass yield, except for rib fat, for which a cubic relationship was found. considering all the results obtained and using the relationship with the highest determination coefficient, the ribs were the cut that provided the best estimate of the carcass muscle and fat yields of f1 crossbred goats (boer with females of non-defined racial standard) finished on native pasture.

Abstract: the present study aimed to assess the effect of levels of supplementation with concentrate on the tissue composition of commercial cuts of goats finished in native pasture. it was used 24 non-castrated cross-bred f1 (boer × sprd) goats at the age of 120 days, with initial average body weight (bw) of 15.52 kg distributed in four levels of supplementation with concentrated feed (0.0; 0.5; 1.0 and 1.5% of body weight in dry matter) and slaughtered at 25.12 kg; 26.62 kg; 28.56 kg and 29.19 kg, respectively, corresponding to 218 days of life. the carcass was sectioned in the half, and from the left half of the carcass, the following cuts were separated: leg, loin, ribs, shoulder and neck, which were dissected into muscle, bone and fat, with the results expressed in weight and yield of the tissues in relation to the weight of the cut. supplementation incresead the muscle weight, as well as the fat weight and yield and decreased the muscle:fat relationship; however there was no influence on the proportion of muscle in the five studied cuts. therefore, in order to obtain better finished commercial meat cuts, supplementation of 1.0 and 1.5% of body weight is recommended. nevertheless, supplementation is unnecessary for obtaining lighter meat cuts with a good proportion of muscle.

Abstract: the objective of this study was to evaluate the effect of supplementation on the carcass characteristics of crossbred boer goats finished on native pasture. twenty-four boer crossbreed goats were used, 120 days old and with an initial 15.52 kg bw. the supplemental feeding was randomly assigned to the animals according to a completely randomized design with 4 supplementation levels (0.0, 0.5, 1.0 and 1.5%) and six replications (goats). the animals had access to the pasture from 7:30 a.m. until 4 p.m. throughout the experimental period and were taken to stalls to receive supplemental feeding in individual cages equipped with hods and a water. full and empty digestive tract (dt) were weighed, as well as the bladder and gall bladder to obtain the empty body weight (ebw). the visceras yield tended to be different from that observed for absolute weight, except for hoof yield that presented a decreasing linear behavior. the hot and cold carcass weights and the yields and the empty body weight and the biological yield presented positively response to the supplementation levels. regarding the participation of wholesale cuts in the carcass, only the neck yield presented linear effect in response to the increase in supplementation levels. full digestive tract and digestive content weights did not respond to the supplementation levels. the digestive content weight was decisive for the effect of supplemental feeding in the full digestive tract weight. wholesale cuts weight responded positively to the supplementation levels.

A suplementa o n o altera a frequência de procura de água por caprinos F1 Boer x SRD terminados em pastagem nativa. Os níveis de suplementa o e as épocas n o influenciaram a procura de sombra. The experiment was carried out at the Federal University of Campina Grande (UFCG), Patos, Paraiba, Brazil. The objective of this study was to evaluate the search for water and shade by Boer goats crossbreeds finished in native pasture under different supplementation levels. Twenty-eight Boer goats crossbreeds, non castrated, with 120 days old and an initial live body weight of 15.52Kg, were used. The treatments were randomly assigned to the animals according to a completely randomized design, with 4 feeding supplementations levels (0.0; 0.5; 1.0 and 1.5% of live body weight on Dry matter) and seven replications (goats). Data were obtained through the observation of the search frequency for water and shade by the animals during the daily grazing in three times: June, July and August. There wasn’t difference among treatments for search for water and the frequency observed was of 71.43, 80.95, 88.89 and 77.78% for the treatments 0.0; 0.5; 1.0 and 1.5% of feeding supplementation, respectively. There wasn’t effect of the treatments in the search for shade and the frequency observed was of 71.43, 85.71, 94.44 and 94.44% in the treatments 0.0; 0.5; 1.0 and 1.5% of feeding supplementation, respectively. The feeding supplementation level doesn't alter the search frequency of water

Abstract: Este trabajo se desarrolla en el contexto de una aproximación externalista de la epistemolo - gía. Se busca reflexio nar de forma unitaria catego - rías como: sentido común, filosofía, ideología, progreso, buen sentido, desde una reflexión sobre la Ciencia y sus procesos. Se toma como punto de partida el horizonte concreto de las prácticas pedagógicas en el campo de las Ciencias Naturales. Para demostrar nuestros objetivos usamos como fundamento teórico-filosófico el marxismo historicista implícito en el pensamiento de Gramsci.

Abstract: Lectin from the seeds of Dioclea sclerocarpa (DSL) was purified in a single step by affinity chromatography on a Sephadex G-50 column. The primary sequence, as determined by tandem mass spectrometry, revealed a protein with 237 amino acids and 81% of identity with ConA. DSL has a molecular mass of 25,606 Da. The β and γ chains weigh 12,873 Da and 12,752 Da, respectively. DSL hemagglutinated rabbit erythrocytes (both native and treated with proteolytic enzymes), showing stability even after one hour of exposure to a specific pH range. The hemagglutinating activity of DSL was optimal between pH 6.0 and 8.0, but was inhibited after incubation with D-galactose and D-glucose. The pure protein possesses a molecular mass of 25 kDa by SDS-PAGE and 25,606 Da by mass spectrometry. The secondary structure content was estimated using the software SELCON3. The results indicate that b-sheet secondary structures are predominant in DSL (approximately 42.3% antiparallel b-sheet and 6.7% parallel b-sheet). In addition to the b-sheet, the predicted secondary structure of DSL features 4.1% a-helices, 15.8% turns and 31.3% other contributions. Upon thermal denaturation, evaluated by measuring changes in ellipticity at 218 nm induced by a temperature increase from 20 °C to 98 °C, DSL displayed cooperative sigmoidal behavior with transition midpoint at 84 °C and permitted the observation of two-state model (native and denatured).

Abstract: The territories exploited by major mining projects of the Amazonian of Pará, Northern region of Brazil, have caused socioeconomic impacts of different complexities and set to debate the role of mining as a tool for territorial planning in the host cities that house Major Mining Projects, for failing to create economic and social dynamics, making the multiplier effect of the Major Mining Projects an indicator of local development of the mineral economy in the municipalities of Pará. The main objective of this paper is to present the main impacts caused by mining activities in Pará municipalities. A documentary and bibliographical analysis was necessary for the textual elaboration, in addition to field research in the study area. We can observe that mining is an important productive activity, but has caused significant changes in Pará territory, as well as in economy and in the environment, and the way of life of local populations.

Abstract: This essay examines the actions of Major Mining Projects in the region of Carajás, the state of Pará, Northern Brazil, which concentrates the projects of one of the largest mining companies of the Planet, the Vale Group, and the relations of power and authority in land use in the corresponding area to the former city of Marabá. The territories exploited by major mining projects, also increase land use that has not been translated into socio-economic development, and add little value to labor and the product. Another issue is lack of a National Mining Policy that truly establishes the regional supply chains, and conducts the multiplier effects to produce new territorial jurisdictions. Mining contributes to socio-economic development of the Amazon region, especially in the Carajás region and promotes the economic organization of the territories for the consolidation of municipalities in which society in its favor uses natural resources. The main objective of this paper is to present the main impacts caused by mining activities in Pará municipalities. Textual elaboration was necessary documentary and bibliographical analysis, in addition to field research in the study area. We can observe, that mining is an important productive activity, but has caused significant changes in Pará territory, both in economy and in the environment, and the way of life of local populations.
