Published: December 2016

RESUMO: Cambissolos são solos poucos desenvolvidos caracterizados, de modo geral, como muito rasos, distróficos e com limitações físicas ao uso agrícola. Os sistemas agroflorestais (SAFs) surgem como uma alternativa de produção agrícola, que preserva a estrutura e a qualidade do solo. O objetivo do presente estudo foi avaliar o efeito da utilização do sistema agroflorestal, sobre as características eletroquímicas de um Cambissolo Húmico, na região do Planalto Serrano de Santa Catarina. A área experimental de 0,8 ha conduzida em sistema agroflorestal na cidade de Curitibanos-SC tem como tratamentos: SAF-Erva Mate (SE), SAF-Frutífera (SF), SAF-Agrícola (SA) todos implantados em outubro de 2013 e uma área de Vegetação Nativa (VN) como testemunha. Foram abertas trincheiras aleatórias em cada tratamento para a coleta de amostras de solo com estrutura alterada nas profundidades 0,0-0,05m e 0,05-0,20m no primeiro semestre de 2014 e 2015 para determinação dos atributos eletroquímicos: balanço de carga (∆pH), ponto de carga zero (PCZ), Carbono Orgânico (CO) e Matéria orgânica total (MOS). Houve um aumento nos valores de pH em água. Por meio do ΔpH verificou-se que o Cambissolo húmico é eletronegativo, a superfície dos coloides apresentaram carga líquida negativa bem como o solo apresenta baixo PCZ devido a grande quantidade de matéria orgânica (≈ 70 g kg-1) . A diversidade de espécies vegetais presente no sistema agroflorestal manteve as características químicas intrínsecas do Cambissolo Húmico, alto conteúdo de matéria orgânica, eletronegatividade dos colóides organominerais, baixos valores de pH e PCZ.

Producing randomness between plots in pepper and snap bean experiments
Authors: Benz Vilson , Lúcio Alessandro Dal’Col
Published: December 2016

It is important to know the production variability among experimental plots in a protected environment because this information reduces error and increases the reliability of the results. Therefore, the objective of this study was to characterize the spatial independence of fruit yield between plots of peppers and snap beans. Data on production uniformity were gathered from trials performed at the Department of Plant Science, Federal University of Santa Maria. Different plots sizes were created according to the number of plants in the crop row. To verify the randomness of the data distribution, we applied a sequence test between the plots within one line for individual and combined harvests. The use of ten plants per plot in experiments with peppers led to no randomness within the lines during the production of fruit fresh biomass. In experiments with snap beans conducted in a greenhouse, a plastic tunnel and by unprotected cultivation using plots with six or more basic units, 12 or more plants per plot produced random fresh biomass data for fruits within the crop row.

Published: December 2016

The goal of the present study was to assess the effect of drying on the physical properties of adzuki bean (Vigna angularis Willd.). Adzuki beans with moisture content of 47.9% were dried in a oven with forced air ventilation at temperatures of 40, 60 and 80 °C and relative humidity of 18.5, 8.6, and 3.8%, respectively, until the moisture content reached 12.9%. We used 15 adzuki beans individualised in aluminium capsules. The orthogonal axes of the beans (length, width, and thickness) were measured at intervals of five percentage points during the reduction of moisture content. The parameters determined were: sphericity; circularity; volume of beans; volumetric contraction index; volume contraction percentage; surface area; projected area; and surface-volume ratio. The drying conditions altered the physical properties of adzuki bean. As a result of moisture content reduction, there was increased sphericity and surface-volume ratio, and decreased volume, unitary volumetric contraction, surface area, and projected area. Circularity was not influenced by the drying temperatures within the range of moisture content analysed.

Published: December 2016

This study evaluated the growth, yield, and postharvest quality of eggplant grown under different foliar fertilizer treatments with Spirufert® (Spirulina platensis). The treatments consisted of four fertilizer concentrations applied at four phenological stages: M1 (10, 15, 25, and 35 g L-1), M2 (15, 20, 30, and 40 g L-1), M3 (20, 25, 35, and 45 g L-1), and M4 (control plants, water spraying only). For Postharvest experiments were conducted in a 4 x 5 factorial design corresponding to the four treatments in the field experiment and five storage times. Spirufert® applied at lower concentrations (M1) resulted in greater fruit yield without affecting the foliar concentrations of N, P, K, and Na. Higher fertilizer concentrations (M3) increased vegetative growth but reduced eggplant yield. Fruit color parameters and soluble solids contents were not affected by fertilizer application, but pulp firmness was more stable in M1 fruits stored for up to six days.

Published: December 2016

In no-tillage (NT) soils, changes in the quantity and quality of soil organic matter (SOM) have been observed over time. These changes can interfere with the dynamics of P in surface soil layers. Thus, the objectives of this study were: to evaluate the organic and inorganic fractions of P and their degree of lability (labile, moderately labile, and moderately recalcitrant) in an Oxisol under NT for 6 years (NT6), 14 years (NT14), and 22 years (NT22) and cultivated with a succession of soybean and corn/wheat. The fractions were evaluated for 16 years of NT, with the last four years under integrated corn second crop and Brachiaria (NT16+B). We also analyzed an area of native forest, as well as analyzing the correlations between the results of the P fractions of these areas with other attributes such as total carbon content, vegetable waste deposited on the ground, phosphorus and humic fractions remaining in SOM. From each of the areas, samples were collected at 0.00-0.05 m and 0.05-0.10 m. A completely randomized design with 5 replicates was used. Management of phosphorus fertilization and SOM following adoption of the SPD of time (6 to 22 years) increased the levels of all fractions of inorganic P (0.0 to 0.10 m), as well as the fractions of labile (0.05-0.10 m), moderately labile (0.0-0.10 m), and moderately recalcitrant (0.05-0.10 m) organic phosphorus. The correlation matrix shows interactions between the evaluated soil attributes, especially between inorganic phosphorus fractions and fulvic and humic acids and between the moderately recalcitrant organic phosphorus and humin fraction.

Published: December 2016

Beneficial effects of silicon (Si) in the plants growth under conditions of drought stress have been associated with to uptake and accumulation ability of element by different species. However, the effects of Si on soybean under water stress are still incipient and inconclusive. This study investigated the effect of Si application as a way to confer greater soybean tolerance to drought stress. The experiment was carried out in 20-L pots under greenhouse conditions. Treatments were arranged in a randomized block design in a 2 × 4 factorial: two water regimes (no stress or water stress) and four Si rates (0, 50, 100 and 200 mg kg–1). Soybean plants were grown until beginning flowering (R1) growth stage with soil moisture content near at the field capacity, and then it started the differentiation of treatments under drought by the suspension of water supply. Changes in relative water content (RWC) in leaf, electrolyte leakage from cells, peroxidase activity, plant nutrition and growth were measured after 7 days of drought stress and 3 days recovery. The RWC in soybean leaves decreased with Si rates in the soil. Silicon supply in soil with average content of this element, reduced dry matter production of soybean under well-irrigated conditions and caused no effect on dry matter under drought stress. The nitrogen uptake by soybean plants is reduced with the Si application under drought stress. The results indicated that the Si application stimulated the defense mechanisms of soybean plants, but was not sufficient to mitigate the negative effects of drought stress on the RWC and dry matter production.

Published: December 2016

The snap bean (Phaseolus vulgaris L.) is an economically important vegetable in Brazil. Bean plants can establish symbiotic associations with bacteria that fix atmospheric nitrogen. These associations show specificity of host plants to certain bacteria. Nitrogen fertilization constitutes a crop production cost, and the use of Rhizobium inoculation to supply nitrogen to crops may decrease the production costs. The aim of this study was to evaluate the effects of inoculation of three different snap bean cultivars with three Rhizobium tropici strains on agronomical performance of the plant. A completely randomized experimental design was used, with a 3 ? 5 factorial scheme and four replicates per treatment. The factors tested were three snap bean cultivars (UEL 1, Alessa, and UEL 2), and five types of inoculation (uninoculated control, inoculation with SEMIA 4077, SEMIA 4080, SEMIA 4088, or with a mix of the three strains). The experiment was conducted in a greenhouse. Plant height, stem diameter, pod length, the number of pods per plant, and average weight and yield of commercial-grade pods, were determined. An analysis of variance was conducted using the F test, followed by Tukey’s test (p < 0.05). Inoculation had a positive effect on all the parameters quantified. The beneficial effect was more pronounced in plants inoculated with the mix of Rhizobium strains.

This study aimed to evaluate the adaptability and phenotypic stability of 10 soybean genotypes in 12 environments in Paraná state by using the additive main effects and multiplicative interaction analysis (AMMI) and Eberhart and Russell models. The assays were conducted in a randomized complete block design with three replicates, in the 2010/2011 season in four locations in Paraná state (Assaí, São Pedro do Ivaí, Cornélio Procópio, and Marilândia do Sul), and with three sowing dates (15/-20/10/10; 29/10-03/11/10; 15/-20/11/10). The cultivars tested with Roundup Ready® technology included SYN 1049, SYN 1152, SYN 1059, SYN 3358, SYN 1163, SYN 1157, V-MAX, FT Campo Mourão, BMX Potência, and SYN 9070. The yield character was analyzed. Data were submitted to analysis of variance and the adaptability and stability were then analyzed. The results of the AMMI and Eberhart and Russell models were somewhat consistent for the stability parameter only. The AMMI analysis was able to capture 66% of the variance associated with residue no additives, of which 43.18% was retained in the first principal component of interaction and 23.58%, in the second component. This is sufficient to explain the genotype × environment interaction. The SYN 1059, SYN 1163, and VMAX genotypes are distinguished by their considerably higher yield and productive adaptation. In the AMMI analysis, the cultivar SYN 1163 showed commercial promise among the other cultivars for high grain yield performance, adaptation, and response predictability.

Published: December 2016

Vinasse is a potassium-rich waste generated in large amounts by the ethanol production that, applied in the soil, can promote changes in water dispersible clay and in its physical quality. The aim of this study was to evaluate the clay dispersion of Oxisols after vinasse application and correlate it with some chemical attributes. Samples were collected in two Oxisols (155 and 471 g of clay kg-1), put in pots, received dosages of vinasse (0, 50, 100, 150 and 200 m3 ha-1) and remained incubated during 120 days. Phosphorous, organic carbon, pH H2O, pH KCl, pH CaCl2, Al3+, H+Al3+, Ca2+, Mg2+, K+, Na+, Delta pH and the proportion between monovalent and bivalent cations have been evaluated and correlated with the clay flocculation degree. Vinasse changed almost all chemical variables in both soils and increased the flocculation in the sandy soil, but did not change the clayey one. Delta pH, Mg2+ and K+ significantly correlated with the flocculation degree in the sandy soil. It is possible to conclude that the dispersive effect of K+ added by vinasse are irrelevant, considering the flocculant effect caused by the increment in Mg2+ and Delta pH after vinasse application.

Published: December 2016

Leishmaniosis are zoonoses that present several clinical manifestations in humans and have dogs as their main reservoir in the urban environment. Visceral leishmaniasis (VL) is the most severe form of the parasitosis and has been increasing in Brazil, despite the actions of public health agencies. Until 2002, the State of Rio Grande do Sul (RS) was considered free of human and canine leishmaniasis. The first human case of cutaneous leishmaniasis in RS was recorded in 2003. In 2009, the first autochthonous cases of human VL and canine visceral leishmaniasis (CVL) were confirmed in São Borja, RS, and the occurrence of the insect vector was recorded for the first time in the state. In 2010, the first confirmed case of CVL was reported and seropositive dogs were identified in the city of Porto Alegre, RS. Given the importance of this zoonosis and the difficulties of a reliable diagnosis in dogs, this study aimed to identify epidemiological aspects of CVL in dogs in an area of Porto Alegre where cases of the disease have been reported. A total of 300 blood samples were collected from dogs in this area, which were then tested by the methods of RT-DPP® and ELISA for diagnosis of Leishmania infantum. An epidemiological questionnaire was completed by dog owners, containing aspects related to care of the animals, characteristics of their environment, and their living conditions. We observed that 83% (250/300) of the studied dogs were of mixed breed, 58% (175/300) were female, 78% (238/300) slept outdoors, and 61% (183/300) shared their living quarters with other species. Clinically, we observed that 90% (270/300) of the animals were infested by ectoparasites, 70% (210/300) had dermatopathies, 24% (72/300) presented weight loss and anorexia, and 22% (65/300) had ocular disorders. The results of the two serological tests were 100% concordant for the three seropositive samples (1%), and the remaining 297 (99%) were negative for both tests. We conclude that despite the low prevalence of L. infantum seropositive dogs, conditions in the region are favorable for CVL transmission, creating a risk of VL for the human population in the city of Porto Alegre.

Recent studies have been carried out to evaluate the role of platelet-rich plasma (PRP) in the cicatrization of wounds; however, the protocols for treatment have been based on a single application of PRP.To evaluate the effect of autologous platelet-rich plasma in gel form on the cicatrization of cutaneous wounds in vivo experimental model, wounds were induced in the dorsal areas of six New Zealand white rabbits with the aid of an 8-mm punch. The right side was used as a control (A) and treated with 0.9% NaCl, whereas the left side (B) was treated serially with the autologous platelet-rich plasma gel. Lesions were assessed over a 17-day period. At days 0, 10 and 17, the animals were evaluated and morphological and morphometric analyses of the wounds were performed. At day 17, a biopsy was performed for histopathological evaluation. Macroscopically, wounds treated with PRP showed better cicatrization and higher contraction percentages than the control wounds. Regarding the percentage of wound contraction, it was found that the average treated wound with autologous platelet-rich plasma gelwas 95% while withthecontrolwas88%. We concluded that autologous platelet-rich plasma gel is effective and accelerates cicatrization when used serially in short intervals, thus confirming its therapeutic potential in cutaneous lesions and potential as an alternative wound treatment option.

Published: December 2016

Bovine cysticercosis is a zoonotic parasitic infection caused by the larval stage (Cysticercus bovis) of Taenia saginata. This study aimed to identify prevention and control measures for bovine cysticercosis indicated by experts in the fields of public and animal health. The study was conducted through three rounds of the Delphi method and had the participation of 44 experts from 13 Brazilian states in 30 educational institutions, research institutions, and sanitary inspection services. The first round comprised an open question, the answers to which formed the basis for structuring the second and third questionnaire. To reach a consensus in the second and third rounds, experts were asked to express their agreement or disagreement of each proposition on the questionnaire using a five-point Likert scale. A descriptive statistical analysis was performed at the end of each round. Twenty-three specialists (52.27%) participated in all three rounds. The first round resulted in 28 proposals categorized into six areas: health education, methods of diagnosis and treatment, sanitation measures, epidemiological studies, legislation and sanitary supervision, and intersectorality. In the second round, the experts reached a consensus on 16 propositions (57.14%). This percentage increased by 3.54% during the third round. At the end of the third round, the experts had reached a consensus on 17 of the 28 initial propositions (60.71%). The highest percentage of agreement (29.4%) was observed in the category of health education. This study allowed us to identify 17 recommendations pertaining to the prevention and control of bovine cysticercosis. These measures are not mutually exclusive, and require an integrated approach to the establishment of intervention actions at various points in the life cycle of the parasite.

Cryptosporidium spp. and Giardia spp. are parasites and have been reported in many species of mammals, including humans. The goal of this research was to investigate the occurrence of Cryptosporidium spp. and Giardia spp. in 45-days-old pigs. Fecal samples of 107 pigs were collected at three alternate days in piggeries in Araçatuba, São Paulo State, Brazil. Cryptosporidium oocysts were observed in 4.7% (5/107) of animals by Kinyoun acid-fast stain method and cysts of Giardia spp. were observed in 1.9% (2/107) of the animals by the method of Faust. Of all animals, 85 presented feces with normal consistency and 22 showed diarrhea in at least one collection. Two diarrheic samples showed positivity for both Cryptosporidium spp. and Giardia spp. From these results it is possible to infer that the occurrence of Cryptosporidium and Giardia was low because of the good management practices and both protozoa were not associated the presence of symptoms.

Published: December 2016

Porcine virus type 2 (PCV2) is an emergent virus found in commercial pig farms and may cause clinical or subclinical infection. Wild pigs such as collared peccary (Tayassu tajacu) and white-lipped peccary (Tayassu pecari) may also be infected by PCV2. Accordingly, the aim of this study was to molecularly identify PCV2 in whole blood samples of captive peccaries (16 collared and 6 white-lipped) by conventional and quantitative PCR (qPCR). Although the housekeeping gene (?-actin) DNA was successfully amplified, all 22 peccaries tested negative for PCV2 by both molecular methods. Previous studies have shown no antibodies against PCV2 in 49 free-range collared peccaries of Southern Brazil but PCV2 DNA was detected by PCR in tissue samples of 9/10 (90.0%) collared and 3/3 (100%) white-lipped free-ranging peccaries from Central and Northern Brazil. In conclusion, although PCV2 may be endemic in free ranging wild pigs of Central and Northern Brazil, lack of serological and molecular PCV2 evidence (in whole blood) of both captive and free-range wild pigs may indicate low risk of disease in Southern Brazil.

Published: December 2016

The study of wound healing and its treatment is extremely important in veterinary medicine due to the high frequency of wounds and the difficulty in treating wounds by second intention. Thus, the objective of this study was to evaluate the use of a nanofiber membrane made of biodegradable polymers as a method of wound treatment in dogs. This study comprised two dogs with bite wounds. Debridement and cleaning was performed followed by the application of the membrane. In one dog, the wound was in the left proximal calcaneal region with clinical signs of infection, necrotic tissue, and muscle and the gastrocnemius tendon were exposed. The wound displayed rapid formation of granulation tissue which became excessive, so it was necessary to debride several times. However, with the suspension of the use of the membrane, formation of this tissue was not observed, and the wound evolved to epithelialization and fast contraction. In the second dog, there was a deep wound on the medial aspect of the proximal right hind limb, with clinical signs of infection, with muscle exposure. Once the membrane was placed, granulation tissue formed, and the membrane was used until the level of this tissue reached the skin. The wound underwent rapid epithelialization and contraction, without developing exuberant granulation tissue. Efficient wound repair was observed and the dogs exhibited greater comfort during application and use of the membrane. More studies should be conducted in dogs focusing on the application of this membrane until the appearance of healthy granulation tissue, as continued use seems to stimulate the formation of exuberant granulation tissue.

Authors: Carvalho Armando De Mattos , Hussni Carlos Alberto , Alves Ana Liz Garcia
Published: December 2016

Tendinitis is an important high-relapse-rate disease, which compromises equine performance and may result in early athletic life end to affected animals. Many therapies have been set to treat equine tendinitis; however, just few result in improved relapse rates, quality of extracellular matrix (ECM) and increased biomechanical resistance of the treated tissue. Due to advances in the regenerative medicine, promising results were initially obtained through the implantation of mesenchymal stem cells (MSC) derived from the bone marrow in the equine tendon injury. Since then, many studies have been using MSCs from different sources for therapeutic means in equine. The adipose tissue has appeared as feasible MSC source. There are promising results involving equine tendinitis therapy using mesenchymal stem cells from adipose tissue (AdMSCs).

The percentages of different implanted area with forage peanut did not affect the production parameters of pasture and structural composition of cultivars. The use of 75% of the area planted with forage peanut promoted share of close to 30% of the total mass of legumes. The leaf:stem ratio was higher for cv. Tifton 85 in daily average temperatures milder, in this situation, both cultivars decreased the forage rate accumulation. The increasing percentage of implanted area with forage peanut increased participation of legumes, decreasing the presence of dead material in the pasture, in the second year of evaluation.

The goal was to evaluate the chemical composition and fermentation pattern of elephant grass (Pennisetum purpureum Schum. cv. Roxo) silage with different levels of soybean hulls or rice bran. Two trials were conducted, comprising of a completely randomized design, with four replicates each. Treatments consisted on the addition of 0%, 5%, 10%, and 15% of soybean hulls or rice bran to unwilted green elephant grass forage. Large PVC silos were used adopting a density of 600 kg of green mass m-3. The silos were opened 40 days after ensiling. The results revealed that the inclusion of 10% soybean hulls increased elephant grass forage dry matter (DM) content to 31%, but did not alter the water soluble carbohydrate (WSC) content or buffering capacity. The resultant silages exhibited good fermentation patterns in terms of pH (less than 3.97) and NH3-N (4.07% total N) levels. The inclusion of rice bran increased both DM and WSC content in the forage, improving the fermentation pattern of silages (P < 0.05). This too was verified by a pH lower than 3.92 and a maximum NH3-N of 4.23% of the total N. The inclusion of 10% rice bran to the elephant grass improved the nutritional value of the forage to be ensiled and, hence, of the produced silage.

This study assesses the effects of technical and managerial indexes on the cost-effectiveness of 20 demonstration units (DUs) that participated in the “Full Bucket” (“Balde Cheio”) program, at different stages of production, in the state of Rio de Janeiro, from January to December 2011. Here, cost-effectiveness was assessed by considering gross margin, net margin, result (financial profit or loss), cost-effectiveness, and profitability as indicators of financial efficiency. Data were analyzed using PASW 18.0. A multiple linear regression model was used with the stepwise method to identify the managerial, technical, and other indexes that most affected profitability and cost-effectiveness. The production systems were categorized into three production levels: small (nine DUs), medium (nine DUs), or large (two DUs). The managerial and technical indexes differed according to the stages of production under study. The daily milk production for the three categories were below 151 kg, 151 to 400 kg, and above 400 kg, respectively. The best profitability and cost-effectiveness at the large production level resulted from selling livestock. This level showed greater animal/day productivity (kg of milk), the best cows/farm manpower ratio, and the best number of herd animals/farm manpower ratio, whereas the medium level showed a lower fixed cost/total cost relation. The small production level showed the best percentages of lactating cows, cows in the herd, and lactating cows in the herd, as well as the best productivity/ha/year and lactating cows/ha. However, the latter results were not sufficient to generate a profit, owing to the small scale of production.

This study evaluated the feeding behavior of lactating cows on pasture of Brachiaria (Urochloa) decumbens fed with concentrate supplementation containing different levels of castor meal inclusion treated with calcium hydroxide Ca (OH) 2, in the proportions of 0; 3.3; 6.6 to 10% of the total diet. Eight cows (degree of blood ½ to ¾ Holstein x Zebu), with previous average production of 3000-4000 kg adjusted to 300 days of lactation and average body weight of 465.16 kg ± 65.45 kg were distributed in two 4 x 4 Latin squares. The behavior was assessed every five minutes for 24 hours on the 21st day of each period. The results were tested by analysis of variance and regression at p < 0.05 probability. The time spent in grazing, rumination, idle and in the trough; total chewing time, number of cuds per day, chewing per day; chewing per cud; the number of periods of grazing, rumination, idle and in the trough; time spent by period of grazing, rumination, idle and in the trough were not different between treatments. The feed efficiency (g DM h-1; g NDFa h-1 and g TDN h-1) and time spent per cud ruminated TSR sec cud-1) were linearly reduced. It is recommended to include up to 10% castor meal treated with Ca (OH)2 in the total diet.

This study was carried out to evaluate the influence of a synthetic progesterone ear implant on weight gain and meat quality of Nellore heifers. Twenty-eight Nellore heifers with an average initial weight of 240.9 kg were used in this experiment. All heifers received the same dietary management, in an intensive rearing system, with mineral salt and water ad libitum. Heifers were distributed, in a completely randomized design, into two treatments (with and without progesterone ear implant) with seven replications, in 14 stalls. Analysis of variance was performed, and, for non-parametric variables, the Kruskal-Wallis test was applied. Parameters referring to the meat quantitative and qualitative characteristics, represented by the weight and yield of the carcass, conformation, marbling, color, meat texture, carcass morphometric measurements, longissimus dorsi muscle area, and fat thickness, were not affected by the progesterone hormone. The use of the progesterone ear implant did not change the carcass physical characteristics or the meat quality characteristics.

This study characterized the thermal environment and assessed the physiological aspects of acclimatization of Sindhi and Guzerat heifers in a tropical environment (Brazil) under shade. Eight Sindhi and eight Guzerat purebred heifers (Bos indicus) had their physiological traits measured twice a day (9:00 a.m. and 2:00 p.m.). Environmental data during the experimental period were collected at two-hour intervals between 5:00 a.m. and 5:00 p.m. The temperature-humidity (THI) and the black globe temperature-humidity (BGHI) indices were calculated, and surface temperature (St), respiratory rate (Rr), and rectal temperature (Rt) were collected, being used to estimate heat loss by cutaneous (Ec) and respiratory (Er) evaporation. In the warmer parts of the day (1:00 and 3:00 p.m.), the THI and BGHI reached values of 80.26 and 81.25, respectively. There was no significant difference in rectal temperatures between the breeds, but higher values were observed in the afternoon. Heat transfer by cutaneous evaporation reached 118.71±12.91 W.m-2 and 103.43±6.82 W.m-2 at 2:00 p.m. for the Sindhi and Guzerat heifers, respectively. Under these conditions (air temperature was between 29 and 30°C), 84% of the total latent heat loss in Sindhi and Guzerat heifers was represented by Ec. It can be concluded that Sindhi and Guzerat heifers can maintain homeothermy with minimal thermoregulatory effort under shade conditions in a tropical environment.

Published: December 2016

Introdução: A emergência da Web Semântica vem impactando o ambiente de publicações digitais científicas. O crescimento da literatura biomédica em formato digital suscita a questão de que novas descobertas podem ter origem não só nos laboratórios, mas também nas bases de dados bibliográficas e factuais. O formato textual linear dos artigos científicos, voltado para leitura humana, é inadequado ao tratamento por computadores. Objetivos: Contextualizar o problema de pesquisa de modelos semântico para artigos digitais em ciências biomédicas, identificando áreas correlatas e produzindo uma revisão da literatura.Metodologia: A pesquisa é descritiva e exploratória, centrada no problema da de pesquisa, procurando identificar interfaces entre as áreas revistas; a abordagem é qualitativa, os métodos foram pesquisa bibliográfica e documentaria. Resultados: apresentação do estado da arte e principais questões em cada subárea, mineração de textos biomédicos e publicações estendidas/modelos semânticos de publicações; são áreas complementares mas não integradas.Conclusões: Estamos em transição de um modelo de publicação centrado no artigo textual linear para um modelo em que o artigo digital, em um novo formato, é um dos elos de uma rede de recursos interligados e acessíveis simultaneamente, processáveis por programas, tirando partido das tecnologias da Web Semântica.
Um estudo bibliográfico sobre ligação de entidades
Authors: Maia Eduardo Habib Bechelane , Bax Marcello Peixoto
Published: December 2016

Introdução: Ligação de Entidades (LE) é um importante tópico de pesquisa que tem atraído recentemente muita atenção de pesquisadores. Na tarefa de LE, menções textuais encontradas em linguagem natural são ligadas à sua entrada correspondente em uma base de conhecimento. Essa tarefa é desafiadora devido a problemas como variação de nomes, ambiguidade das entidades ou porque a entidade mencionada pode não existir na base de conhecimento.Objetivo: Apresentar os problemas relacionados à LE, suas aplicações típicas, bem como sintetizar suas principais abordagens no contexto da ligação de conceitos.Metodologia: Pesquisa de levantamento junto à literatura vigente, para descrição detalhada do estado da arte das abordagens em LE, bem como para a sistematização e categorização das abordagens identificadas.Resultados: A maior parte dos trabalhos propostos para a LE divide esse processo em duas etapas: reconhecimento e ligação de entidades. No entanto, novas propostas têm unificado estas etapas em um único processo.Conclusão: Apesar de mais complexas, as novas abordagens em LE permitem capturar a dependência entre as decisões de Ligação e de Reconhecimento de Entidades minimizando erros e inconsistências. As avaliações deveriam ocorrer em bases de dados unificadas, considerando a dificuldade de comparar resultados de bases de dados distintas devido à influência que estas exercem nos resultados obtidos.
