Demanda energética na colheita de híbridos de milho para silagem em função do estádio de maturidade e tamanho de partícula

Corn is the crop most used for making silage. The efficiency of the process should also be evaluated by cost per kg of dry matter harvested (kgDM). The objective of this study was to evaluate energy consumption in the harvest of corn hybrids for silage depending on the texture of the hybrid, four and three harvest maturities of particle sizes - Tp was used a tractor Massey Ferguson MF 610 model 86 cv. Cutting and harvesting the forage harvester is used model JF92 Z10. To obtain data on fuel consumption (CC) and time spent for each plot, we used a flow meter, installed near the fuel filter of the tractor. The experimental design was completely randomized in a split plot. The interaction between factors triple stage hybrid * Harvest * Tp. The velocity and displacement of the tractor were different for the maturities for hybrid hard texture. The CC schedule for hybrid dent increased harvest maturity earlier and at lower Tp. Consumption was lower by kgDM later maturity, hard texture and bite respectively. The theoretical power was higher in earlier maturity and yield were higher for hybrid hard texture in the most advanced. The CC was lower in late maturity and the hybrid hard texture can be used for silage in relation to the Cc and income in later maturity in higher Tp.

Alterações hematológicas em cães e gatos sob estresse

The leukocyte count interpretation on the blood helps on understanding about the possible dysfunction showed by the animal. In general, an abnormal leukogram allows the identification of pathological process. A lot of events lead to an increase in the number of neutrophils, among then, inflammatory process, infection and stress. Dependent on the stress mediator that the animal is submited, the leukocyte alteration will be different. Is important to know how the stress acts on the animal organism, changing the hematological parameters, in order to avoid mistakes on diseases‟ diagnosis. It‟s known that after a stress situation, it‟s expected that stress leukogram appears on the hemogram of the animal. However there are different kinds of stress with different responses. It‟s believed that when the animal is under an acute stress situation, a clinical picture of physiologic leukocytosis occurs which is mediated by the epinephrine. This is characterized by neutrophilia, lymphocytosis, monocytosis and eosinofilia. The physiologic leukocytosis is a transient alteration in the leukogram that occurs within minutes of the stimulus and due to fleeting effect of catecolamines it resolves within 20 to 30 minutes. However, if the animal is under chronicle stress, as solitude, it „s expected to find the stress leukogram on the leukogram, that can be noted especially in dogs. The stress leukogram is characterized by leukocytosis, neutrophilia, lymphopenia, monocytosis and eosinopenia. This kind of stress is induced by the glucocorticoids. It´s important to understand that stress leukogram takes time to occur. The variation on time depends on the animal species, although, in general, the glucocorticoides have a peak effects among 4 to 8 hours, which can last from 24 hours to 2 or 3 days

A influência do ciclo estral no comportamento das linhagens de ratos congênica SLA16 e isogênica SHR

Several studies use only male rats in their experiments, even with all the evidence of differences between the sexes, not only in the reproductive behavior but also in the development of diseases. This absence of studies using female rats is due in part to the estrous cycle. It is known that one estrous cycle lasts four to 5 days and consists of four phases: proestrus, estrus, metestrus and diestrus. Ramos et al. (1999) identified and mapped a QTL in an F2 population derived from interbreeding of strains of SHR (spontaneously hypertensive rats) and Lewis (LEW) rats and found, on chromosome 4, the first QTL of the world related to anxiety in rats. After several backcrosses between SHR and LEW strains, it was developed a congenic strain called SLA16, to refine the study of this QTL. This QTL corresponds to a large genomic region, approximately 75 million basepairs (Mb), and was first called Ofil1 (inner open field locomotion 1). Currently it is called Anxrr16 (anxiety-related response region 16) according to the rat genome database (RGD). Izidio et al. (2011) suggested that the natural fluctuation of the hormones in the estrous cycle of female rats could influence the effects of this locus on behavior. That is, females in DP (diestrus-proestrus) present the QTL in the same genomic region that males, while females in EM (estrus-metestrus) do not present it. The effects of the estrous cycle in the SLA16 strain and its isogenic control SHR were analyzed on the elevated plus maze (EPM), black and white box and on the open field test (OF). In the open field test, the SLA16 strain had higher central locomotion (F=5.0, p <0.05) and peripheral locomotion (F=12.6, p <0.01) compared to the SHR strain. In the elevated plus maze test, the SLA16 strain had the higher number of entries (F=9.5, p <0.01) and time spent in the open arms (F=10.3, p <0.01) compared to the SHR strain. Finally, in the black and white box test, the SLA16 lineage spent more time ...

Utilização do cavaco de madeira como combustível alternativo para a produção de vapor de água em uma caldeira aquatubular com grelha fixa do tipo PIN HOLE

The steady increase in the price of oil and its derivatives, carbon credits, the concern with the environment combined with the precipitation of rain water and lack of water resources that Brazil has suffered in 2014 caused a migration of participation sources of energy in the Brazilian energy matrix. The hydropower sector suffered big drop at 2013 and is suffering so far, contributing thus to the generation and cogeneration of thermal energy using renewable energy sources such as: sugarcane bagasse, wood chips, rice husks, among others. The selling price of the electricity market reached the level of R$ 807, 00 MWh in January 2014 (Source: ANEEL), heating the Brazilian thermoelectric sector. Although thermoelectric use in bulk water as vaporizing fluid to produce electricity and use in various processes, water reuse plans have become an important factor in these industries. The increased use of biomass has been the bagasse which is allied to the sugarcane sector, strong market in Brazil, and consists basically use the rest of sugar cane, sugarcane industries that would play out. The sugar and ethanol industry is very unstable and only lasts for 6-8 months a year, and the remaining time in the period known as between crop that corresponds to the planting and harvesting of sugarcane and then enter the period of vintage which is the constant cane harvesting and crushing it. This instability of the market and the thermoelectric idle period leads the thermoelectric industries to seek other sources of renewable energy, such as wood chips (pine, Eucalyptus, Orange), rice husk, sorghum among others, to not be dependent on alcohol sector. The present work aims to study the use of wood chips as an alternative biomass for burning a fuel that essentially uses bagasse, the thermoelectric in question consists of two boilers that produce together 350 t / h ...

Surgical Treatment of Severe Frontal Bone Fracture

Craniofacial trauma can lead to several complications. The combined fractures of anterior and posterior walls of the frontal bone are almost always followed by lesions in nasofrontal orifices and disruption of nasofrontal ostia or ducts, a significant factor for the development of early and late complications after sinus fractures. This article reports a case of trauma patient, who underwent neurological evaluation and at first showed good general condition. Computed tomography noted fracture of the anterior and posterior walls of the frontal sinus and small foci of pneumocephalus in the cerebral cortex. The patient was monitored periodically and 9 days after trauma showed increased areas of pneumocephalus in prefrontal cortex, cerebrospinal fluid draining, and large dura mater lesion, with signs of necrosis and inflammation (meningitis). The necrotic tissues were removed, and dura mater was repaired through the approximation with resorbable wire polyglactin 910 5-0, oxidized cellulose application, and bonding with human fibrin sealant (fibrinogen, thrombin, and calcium chloride). Sinusectomy, frontal sinus, and nasofrontal duct obliteration with pedicled pericranium flap were performed. Tomographically, a reanatomization was noted in frontal region, and a 12-month follow-up showed no complication. The use of fibrin glue to repair dura mater lacerations, as well as the pedicle pericranium flap for frontal sinus and nasofrontal duct obliteration, is an efficient method for treating fractures of the frontal bone.

Degradabilidade e digestibilidade de híbridos de milho em função do estádio de colheita, tamanho de partícula e processamento por meio do esmagamento na ensilagem

During the process of silage corn, should take into consideration some aspects that will result in better utilization. The aim of this study was to evaluate the degradability of dry matter (DM), crude protein (CP), neutral detergent fiber (NDF) and starch digestibility and in vitro dry matter (DM) of silage corn hybrids due two textures, three stages of harvest, three particle sizes and processing by crushing. After harvesting and chipping, part of the material was crushed and then ensiled and sealed for 45 days. After opening the silos, analyzed the degradability in the incubation time of 20 hours using the technique in situ macro bag. The experimental design was a randomized split plot. The DM degradability was influenced only by the effect of stages of sampling used. The degradability of CP showed interaction between processing and particle size (Tp), noting that increased degradation due to processing. For NDF degradation significant interaction of factors, hybrid and processing, similar to the degradation of starch. The IVDMD was influenced by the effects of hybrid, stadium, Tp and processing. It can be concluded that benefits were higher with the use of processing associated with more advanced stages of harvest, in larger particle sizes.

Fatores extrínsecos que afetam a absorção de água em carcaças de frango de corte

O Brasil ocupa uma posição de destaque como produtor e exportador de carne de frango. Um parâmetro importante na qualidade da carne de frango é a quantidade de água absorvida pela carcaça durante o processamento. No Brasil, o resfriamento das carcaças é feito por imersão em água refrigerada e, neste processo, a carcaça é reidratada, recuperando a água perdida durante o transporte e as operações iniciais. Este projeto teve como objetivo avaliar os fatores extrínsecos que podem influenciar a absorção de água pela carne de frango. Para isso, foram utilizados 144 frangos da linhagem Cobb, divididos em 24 grupos de seis aves. Aos 42 dias de idade, uma ave de cada grupo, com peso variando até 10% para mais ou para menos, em relação à média do grupo, foram abatidas em abatedouro experimental. A etapa de resfriamento foi realizada seguindo um delineamento inteiramente casualizado com arranjo fatorial 3x2, onde os fatores foram: três temperaturas na primeira seção do sistema de refrigeração (4, 10 e 16 º C) e dois graus de dureza da água (água dura e água mole), com seis tratamentos e quatro repetições. A legislação brasileira estabelece que a temperatura da água na primeira seção do resfriador não deve ser superior a 16ºC. Todas as carcaças permaneceram na primeira seção do resfriador durante 30 minutos e, em seguida, foram transferidas para outro tanque com água a 4ºC, permanecendo até atingir 7ºC. As carcaças foram pesadas antes e após o resfriamento por imersão, para avaliação da percentagem de água absorvida. A absorção de água foi influenciada pela temperatura inicial da água no pré-resfriador e pela dureza da água. Quando imersas inicialmente em água a 4ºC, as carcaças absorveram, em média, 2,70%, uma absorção significativamente menor do que a média de 3,83% observada nas carcaças que foram inicialmente imersas em água a 16ºC (p<0,05). As carcaças imersas em água a 10ºC apresentaram média de absorção de água de 3,66%, não diferindo das médias observadas nos outros tratamentos (p>0,05). Em água dura, a média de absorção de água foi de 2,46% e, em água mole, de 4,33% (p<0,05). Em todos os tratamentos, a absorção de água não excedeu o limite estabelecido pela legislação brasileira, que é de, no máximo, 8%. Esta informação é importante para controlar a absorção de água pelas carcaças em processamento de carne de frango, impedindo que os consumidores sejam prejudicados.
