Evaluación genética de búfalos de la raza Murrah para la producción de leche en el día de control y a los 305 días de lactancia

There were analyzed 4757 complete lactations of the Murrah breed, daughters of 187 bulls, with the goal of verifying the viability upon employing the test-day (PDLC), on substitution of the milk yield at 305th day of lactation (PL305), in the genetic evaluations. The components of variance for the PDLC1 to PDLC9 and for the PL305 were estimated in uni-traits analysis according to maximum restricted likelihood method. The used model included the genetic direct additive random effects, of residual and permanent environment. There were considered as fixed effects, the contemporary group and the number of milkings and the age of the cow at the moment of parity co-variable (quadratic and linear effect). The contemporary groups were constituted by the herd-year-month of control for the PDLC and by herd-year-epoch of parity for PL305. The estimates of heritability for the PDLC and PL305 were 0.12 to 0.23 and 0.22, respectively. The correlations of order of the predicted genetic values for the 187 bulls, obtained between the PDLC and the PL305, were from moderate to high, varying from 67.74 to 83.12. From the minimum selection of the 10% of the best bulls relating to the predicted genetic value for the PL305, the coincidence among the classification of these animals was over 68%, when evaluated by the PDLC3,PDLC4,PDLC5 and PDLC6. Upon selecting the 5% of the best animals that coincidence presented a lower value.

Sistematização da Assistência de Enfermagem: acidente por Loxosceles gaucho.

Experience report carried out at a university hospital involving a patient victimized by an accident with a spider of the Loxosceles gaucho genus. This type of accident can be classified as mild, moderate and severe, depending on the period of time elapsed between the occurrence of the accident and the moment of care provision. We aimed at applying nursing care systematization in a comprehensive and humanized manner. The following nursing diagnoses were established: acute pain, damaged skin integrity, risks for infection, constipation and low self-esteem. The therapeutic relationship favored student/patient interactions and enabled the recognition of the needs that deserved nursing interventions. The nursing process was a valuable instrument and provided important elements for the patient's daily development and planning adjustment by prioritizing care quality.

Da crítica diplomática à análise tipológica: abordagens e técnicas de análise documental

This study, of an instrumental nature, discusses the theoretical differences which underpin the documentary analysis models used in traditional Diplomatics and Contemporary Diplomatics. Undoubtedly, both models of analysis contribute to the understanding of the sources -a vital point of the process of analyzing the document to be used in any area. Thus, the choice of either technique must take into account the goals proposed for the research, according to the object that is taken as the reference point: the archival series or the individual document. That way, issues such as the evidential value and diplomatic authenticity are important within the Archival Science, which seeks through auxiliary disciplines to verify the historical trail of the document, from the moment of its production, usage and archiving, as well as the various custodians, contributing in a large measure to the understanding of its information -what is registered as well as the context- in its broadest sense.

Fluorescência da clorofila-a e variação da simetria como ferramentas de investigação de plantas sob estresse

Environmental disturbances in various systems and individuals can result in a tendency for fluctuating asymmetry, which consists of a non-directional deviation from symmetry of a bilateral structure in a normally distributed population. Individuals unable to exhibit plastic responses to developmental disorders that occur at random, either genetic or environmental, may exhibit slight deviations from symmetry in organs with bilateral structure such as leaves. Thus analyzing plants by the morphological pattern of symmetry of the leaves has become an effective tool to describe the developmental of plants under stress conditions. This study aimed to analyze if the pattern of symmetry can be used as a tool to investigate the stress level to which a plant is subjected, using ultraviolet-C radiation (UV-C) as source of stress. We determined the leaf symmetry deviations (sd), the average length (AL) and the maximum width of the lamina (MWL) and the fluorescence parameters of chlorophyll-a in leaves of young plants of G. max subjected to 0, 30, 60, 120 or 240 minutes per week of UV-C during four weeks, submitting the values to ANOVA and Tukey test (p <0.05). The results showed significant reductions in AL and MWL, significant increase in sd in leaves irradiated and a drop in potential quantum yield of photosystem II (PSII) and in the photosynthesis performance index (IP). The analysis of leaf symmetry showed high correlation with the stress level to which plants were submitted, being an important analysis to ascertain the fitness of the plant because it is a noninvasive method and easy to perform.

Composição química e digestibilidade in vitro da massa seca de cana-de-açúcar acrescida de ureia em diferentes tempos de estocagem

The objective of this research was to evaluate the chemical composition and in vitro dry mass (DM) digestibility of sugar cane with urea, maintained in the shade and sun, at different storage times. The utilized design was the completely randomized in a factorial scheme 6x2, that is, six storage times after the mixing (0; 2; 4; 6; 12 and 24 hours) and two storage location (shade and sun), with three replicates. The sugarcane utilized presented 12 months of development and was disintegrated for application of mixture (nine parts of urea for one of ammonium sulfate) to 1.0kg/100.0kg of fresh sugarcane. The samples taken with 12 hours of storage indicated that was an increase in the content of DM and crude protein (CP) of sugar cane compared to the moment of the mixture (307.6 vs. 294.2g/kg of DM and 115.2 vs. 99.3 g/kg of DM, respectively), and the smaller content of neutral detergent fiber (NDF) was observed around of 12 hours of storage (465.0g/kg of DM). The coefficients of in vitro dry mass digestibility (IVDMD) ranged of 0.558 to 0.612 in the times 0 and 12 hours, respectively. The length of storage changes the chemical composition of sugar cane plus urea. The storage location changes the dry mass content and pH values.

Quenching in a non-ideal mechanical system and the Averaging Method

In this paper, for the first time, a quenching result in a non-ideal system is rigorously obtained. In order to do this a new mechanical hypothesis is assumed, it means that the moment of inertia of the rotating parts of the energy source is big. From this is possible to use the Averaging Method. © 2012 American Institute of Physics.

Caracterização de agravos causados por cães e gatos a seres humanos no município de jaboticabal, são paulo, durante o período de 2000 A 2009

The lack of proper control of dogs and cats population and irresponsible pet ownership are factors that favor animal attack and pose serious public health concern. The aim of the present study was to characterize the injuries caused by dogs and cats to humans in the municipality of Jaboticabal, between the years 2000 and 2009, with a view to demonstrate the importance of aggression control in reducing both the risk for rabies transmission and the number of post exposure prophylaxis administration. A retrospective and descriptive study was conducted. 3,972 out of 4,149 records of patients who sought the public health service after being attacked by an animal were analyzed. Dogs were the species that most caused injuries. In the moment of the attack, the doǵs clinical status was declared as healthy in 81.8% of records; and in 81.1% of cases this status were maintained throughout the entire observation period of the aggressor. Most of injuries were characterized by bites in hands or feet, with multiple and superficial wounds. The number of injuries was high, therefore it is crucial to implement strategies to reduce injuries caused by animal attack through health promotion, educational activities and strengthening of integration of public health and veterinary services so that the decision to institute post-exposure prophylaxis is taken with criteria and safety.

Consórcio de milho com Urochloa ruziziensis e os efeitos na cultura da soja em rotação

This work aimed to study the intercropping of corn and Urochloa ruziziensis cv. Common, regarding to vegetative growth and corn yield, capacity of production of forage dry matter, the infestation of weeds and the effect of this system of production in the soybean crop in rotation. Two forms of sowing (hand-sowing and on-line sowing) of U. ruziziensis, four amounts of seeds (200, 400, 600 e 800 points of cultural value, PCV = quantities of seeds x cultural value) and one treatment additional with the single corn were studied. The intercropping did not affect negatively the vegetative growth and corn yield when compared to the single corn. The sowing of 200 PCV of U. ruziziensis seeds, hand-sowed and on-line sowed to 22 days after of sowing of the corn was enough for the maintenance of adequate amount of straw on the soil. At the moment of the harvest of the corn, the dry matter of weed reduced with the increase of the amount of U. ruziziensis seeds and was bigger when the forager was hand-sowed. In the soybean crop in rotation, the density and dry matter of weed reduced linearly with the increase of the amount of U. ruziziensis seeds used in the first year of the research. The intercropping of corn and U. ruziziensis in the first year of the experiment benefited the plants population, plants height and yield of soybean when compared to the monoculture of corn in the same period.

Pseudoautotomy in Dendrophidion dendrophis and Mastigodryas bifossatus (Serpentes: Colubridae): Tail Morphology and breakage frequency

The micro and macro structures of the caudal vertebrae and muscles of Dendrophidion dendrophis and Mastigodryas bifossatus were described using histological slides, dissections, radiographs, and clearing and double staining of intact, broken, and healed tails. To analyze the relationship among the frequencies of healed tails we established two populations of D. dendrophis and six groups of M. bifossatus. We found that fractures of the tail in the two species are intervertebral, and there are no morphological and/or structural mechanisms that facilitate the urotomy, which is classified as non-specialized pseudoautotomy. The caudal vertebrae of D. dendrophis and M. bifossatus show minor differences in the shape of the condyle, cotyle, and border of the neural spine, and in the size and orientation of the hemapophysis and pleurapophysis. The absence of bleeding at the moment of tail breakage may indicate the presence of sphincters in the veins and arteries of D. dendrophis. The distal part of the last vertebrae retained in healed tails of D. dendrophis and M. bifossatus participates in the healing processes as a possible source of calcium in the formation of a calcified cap. We found high frequency of tail breakage in both species, which occurs in almost the entire length of the tail, with no specific areas of concentration. There was no difference in the frequencies of healed tails among males and females of different populations of D. dendrophis and M. bifossatus. Juveniles have lower breakage frequencies than adults in both species, except for populations of M. bifossatus from the Cerrado and Pampa. © 2013 by the American Society of Ichthyologists and Herpetologists.
