Pinos transcorticais e gesso associados à aplicação local de plasma rico em plaquetas no tratamento de fratura do III metatarsiano em potro

In horses less than one year of age fractures of the third metacarpal bone (McIII) or metatarsal bone III (MtIII) are mainly attributed to trauma. Open reduction and internal fixation are the most common treatment method. A Quarter Horse filly with three months of age, which weighed 150kg presented a diaphyseal multifragmentar wedge fracture of right MtIII which was treated with transcortical pins and cast, associated with intralesional application of platelet rich plasma (PRP). After two years of surgery, the animal initiated a training program for racing, and six months later, the patient ran its first official match. The choice of therapeutic methods for treating fractures in horses should be one that provides an earlier repair and minor possibility of complications. Thus, the therapy association which was adopted was considered favorable, since allowed full reestablishment of locomotion of the patient and made possible its return to race.

Genotypic characterization of ten microsatellite loci in two Brazilian free range (Caipira) chicken lines

This study aimed to investigate the genetic variability of two Brazilian free range (Caipira) chickens lines using microsatellites analysis of ten loci. It was collected a total of 99 blood samples, which 49 were from Paraiso Pedres (PP) and 50 were from Rubro Negra (RN) lines. The amplification of the DNA fragments was performed by polymerase chain reaction (PCR) and the genotyping was conduct using ABI 3130 sequencer. The allele number variation was among 3 (LEI0254) to 32 (LEI0212) in the PP line, and 4 (LEI0254) to 31 (LEI0212) in the RN line. The allelic average per locus was 13.3 and 13.1 in the PP and RN lines, respectively. The average observed and the expected heterozygosity were 0.650 and 0.820 in the PP line, and 0.671 and 0.804 in the RN line. All of the analyzed loci were informative (PIC>0.5). These results indicate that these free-range animals have a high genetic variability, at least for the majority of the analyzed loci, and this genetic variation is higher than the commercial chickens and similar for the no-commercial birds.

Fenologia reprodutiva da pitaya vermelha em Jaboticabal, SP

The dragon fruit (Hylocereus undatus) is recent crop cultivation in Brazil and there is still lack of studies to support the farmers. So, this research aimed to characterize the reproductive phenology of the crop in the region of Jaboticabal, Sao Paulo State, Brazil. It was evaluated red dragon fruit clones over two environmental conditions - under plastic screen black and white, with 50% of shady level, from March 2009 to December 2010. It was observed that the issuance of floral buds and the flowering on dragon fruit culture occurs with a combination of high temperatures and rainfall, with constant emission of floral buds from November to March while the flowering on dragon fruit culture occurs until mid-April. The color of plastic screen had influenced on amount of flowers. The time elapsed since the issuance of flower buds to anthesis is from 18 to 23 days, while the harvest occurs from 34 to 43 days after flower opening. At Jaboticabal, the time of appearance of flower bud to fruit harvest is from 52 to 66 days.

Compostagem de resíduo sólido de abatedouro avícola

The great demand for animal protein was responsible for the increase on the broilers production and hence, the generation of waste from the poultry slaughter was increased as well, which in turn, propelled the development of techniques that allow the reuse and recycling of these wastes. The objective of this study was to evaluate the efficiency of composting on the treatment and recycling of solid waste from poultry slaughterhouse. The solid waste was from a commercial poultry slaughterhouse and was composed of viscera, muscle, fat, bone, blood and feathers that was mixed with a source of carbon, rice husk. Initially, a windrow with a volume of 1.5m(3) was built, and then some parameters were monitored: temperature, total solids (TS), volatile (VS), N, P, K, organic carbon (C), composting organic matter (COC), organic matter resistant to composting (MORC), chemical oxygen demand (COD), mass and volume of the windrow, most probable number (MPN) of total and fecal coliforms, as well as their reductions during the process. The maximum temperature reached in the center of the windrow was 53.3 degrees C (weekly average) since reductions of weight of TS and VS and volume during the pre-composting were 36.1, 44.3 and 23.3%, respectively and during the composting process was 21.8, 23.8 and 4.4%. The low volume reduction can be associated with high concentrations of MORC (40.1%) which can be mainly related to the quality of the carbon source. The process produced satisfactory total reductions of TS, VS and volume that were respectively, 50.1, 57.5 and 26.7%. However reductions were observed in 43% of amount of nitrogen in the final compound. Despite reductions in nitrogen content, composting proved to be an effective method in the treatment of solid waste from poultry slaughterhouse.

Behavior of Staphylococcus aureus and autochthone microbiota in fresh sausages added of sodium nitrite and stored under refrigeration

Fresh sausages are cured meat products that may be contaminated with Staphylococcus aureus during the manufacturing procedure, which is frequently related with inadequate handling practices. The use of nitrite in meat products has proven efficacy against Clostridium botulinum, and studies indicate that bactericidal action against S. aureus depends on factors that are intrinsic and extrinsic to the product. The objective of the present study was to evaluate the effect of nitrite concentration, and pH on S. aureus and psychrotrophic autochthone microbiota in fresh sausages stored at different times and temperatures. Fresh sausage were produced at nitrite concentrations 50, 150 and 200ppm and contaminated with S. aureus. The sausages were storage at refrigeration (7 and 12 degrees C) and the quantification of S. aureus and psychrotrophic microorganisms was carried out on days 0, 2, 4, 7, and 10. Results showed that nitrite concentrations and the temperatures used had minimal effect on the multiplication of S. amens and psychrotrophic autochthone microbiota. Final counts depended only on the length of storage: at the end of 10 days, counts were statistically similar in the different groups, showing that temperature and nitrite concentrations used did not control microbial growth effectively. It is suggested that the product should be stored below 7 degrees C or at freezing temperatures for greater microbiological stability.

Aplicação de modelos de regressão aleatória utilizando diferentes estruturas de dados

A total of 3.035 lactations of Holstein cows from four farms in the Southeast, to check the influence of data structure of milk yield on the genetic parameters. Four dataset with different structures were tested, weekly controls (CW) with 122.842 controls, monthly controls (CM) 30.883, bimonthly controls (CB) with 15,837 and quarterly controls (CQ) with 12,702. The random regression model was used and was considered as random additive genetic and permanent environment effects, fixed effects of the contemporary groups (herd-year-month of test-day) and age of cow (linear and quadratic effects). Heritability estimates showed similar trends among the data files analyzed, with the greatest similarity between dataset CS, CM and CB. The dataset submitted all the CB estimates of genetic parameters analyzed with the same trend and similar magnitude to the CS and CM dataset, allowing the claim that there was no influence of the data structure on estimates of covariance components for the dataset CS, CM and CB. Thus, milk recording could be accomplished in a CB structure.

Elaboração e implantação do sistema de análise de perigos e pontos críticos de controle no processamento de leite pasteurizado tipo A

Hazard analysis and critical control points (HACCP) is one of the main tools currently used to ensure safety, quality and integrity of foods. So, the aim of this study was to develop and implement the HACCP program in the processing of pasteurized grade A milk Checklists were used to assess on the level of the pre requisites programs and on the sanitary classification of the dairy industry and the results were used as references for the development of the HACCP system. A "decision tree" protocol was used for the identification of the critical control points (CCP). No physical or chemical CCP were identified, whereas pasteurization and packaging were considered biological CCP For these CCP, the limits for prevention, monitoring needs, corrective actions, critical limits and verification procedures were established. The pre requisites program was essential for the establishment of the system. The implementation of the HACCP for the processing of grade A pasteurized milk was efficient to control the biological hazards and enabled the product to comply with the legislation specifications and achieve safety.

Les conflits et les rapports de force dans la langue. Le dominant et le domine dans le domaine scolaire

La standardisation de la langue française a inévitablement eu des conséquences soit dans l’attitude de défense du français, soit dans l’inquiétude de ceux qui parlent une autre langue. Cette étude veut établir une comparaison entre le rapport langue du pouvoir/langues non officielles et le rapport professeur/élève en milieu scolaire. La distinction entre langue officielle et dites « langues minoritaires » sera mis en relation avec la langue des jeunes, qui, à l’école, se confrontent et entrent en collision avec la langue de leur professeur. En effet, les classes hétérogènes et l’influence de la langue maternelle auprès des élèves, fils d’immigrés, exposent les enseignants à toute une série de difficultés liées aux différences culturelles. Les dénonciations et les cas de violence dans les écoles mettront l’accent également sur l’opinion publique et sur le type de mesures mises en relief par les Institutions publiques. L’aire géographique prise en considération inclut Paris et ses environs même si quelques exemples d’enquêtes menées dans d’autres parties de la France et à l’étranger seront cités.

La valutazione del rischio di incidente rilevante per i depositi di fitosanitari

I prodotti fitosanitari sono sostanze attive e preparati, contenenti una o più sostanze attive, destinati a proteggere i vegetali, a favorire e regolare i loro processi vitali, a conservarli, a eliminare le parti non necessarie, a frenare o evitare un loro indesiderato accrescimento, ad eliminare le piante indesiderate. Il prodotto fitosanitario è composto normalmente da tre tipologie di sostanze: sostanza attiva, coadiuvante e coformulante. Le sostanze attive rappresentano la parte del prodotto fitosanitario che serve a combattere l’avversità che si vuole controllare, cioè la sostanza tossica che, a seconda della pericolosità e della concentrazione presente nella formulazione, concorre a determinare la classe di tossicità e quindi di pericolosità del prodotto. Gli stabilimenti che detengono fitosanitari sono suddivisi in depositi e siti produttivi. Secondo la classificazione dell’ISPRA, i depositi di fitosanitari costituiscono una delle 15 categorie di attività a rischio di incidente rilevante, mentre, i siti produttivi rientrano nella categoria degli stabilimenti chimici e/o petrolchimici. Il presente lavoro di tesi ha riguardato la valutazione del rischio di incidente rilevante per i depositi di fitosanitari, con particolare attenzione al rischio associato alla produzione di composti tossici a seguito di scenari incidentali di incendio. È stata in primo luogo effettuata una ricerca approfondita finalizzata a comprendere che cosa sono i prodotti fitosanitari, a quale scopo servono e quali sono i rischi ad essi associati. Successivamente, è stato effettuato un approfondimento delle norme a cui i siti che producono e detengono fitosanitari sono soggetti. È stato quindi effettuato un censimento per individuare quali e quanti sono i depositi e i siti di produzione di prodotti fitosanitari suscettibili di causare incidenti rilevanti in Italia. Si è poi proceduto all’analisi storica sulle banche dati MHIDAS, E-MARS ed ARIA, al fine di individuare gli eventi incidentali che hanno interessato depositi e siti produttivi di fitosanitari. Successivamente, si è analizzato il Regolamento CPR-15, quale metodo raccomandato dal ministero olandese VROM (Ministerie van Volkshuisvesting, Ruimtelijke Ordening en Milieu) per la valutazione del rischio associato a depositi di fitosanitari. Come applicazione della metodologia per la valutazione del rischio descritta dal Regolamento CPR 15, è stata effettuata la modellazione di uno scenario di incendio in un deposito reale di fitosanitari attraverso il Warehouse Model, implementato nel software PHAST 6.54. La simulazione ha portato a definire l’estensione delle aree di danno associate alla dispersione dei fumi tossici prodotti dall’incendio.

Charakteristika schwer essgestörter Patientinnen in einer universitären Einrichtung und therapeutische Richtlinien

Patientinnen und Patienten mit einer schweren Essstörung (Anorexie, Bulimie, weitere) finden einerseits selten Eingang in systematische Studien, sind andererseits aber häufig auf ein stationäres Behandlungssetting in einem tertiären Zentrum angewiesen. Die kürzlich veröffentlichte S3-Leitlinie zur Behandlung von Essstörungen erlaubt eine klarere Einschätzung der Hospitalisationsbedürftigkeit schwer Essgestörter als bisher. In der vorliegenden Arbeit wurden 26 Patientinnen und Patienten mit einer schweren Essstörung, die konsekutiv auf einer spezialisierten psychosomatisch/internistischen universitären Einrichtung hospitalisiert wurden, retrospektiv hinsichtlich ihrer biologischen, psychologischen und sozialen Merkmale charakterisiert und in Bezug zur S3-Leitlinie gestellt. Die biopsychosozialen Charakteristika der untersuchten Population zeigen, dass die Hospitalisierung schwer Essgestörter im tertiärmedizinischen Setting mit einem multiprofessionellen Behandlungsteam evidenzbasiert erfolgt.

Perfil de los extensionistas rurales argentinos del sistema público

Pese la importancia de la extensión rural en toda estrategia orientada el desarrollo de los sectores de productores rurales pequeños y medianos, no existen en la Argentina trabajos académicos que reconstruyan de manera completa y sistemática el perfil de quienes trabajan en el país en extensión rural. Por esta razón, se realizó una investigación cuantitativa descriptiva de carácter transversal que permitió reconstruir el perfil de los extensionistas rurales que trabajan en el sistema de extensión público argentino. Para este fin se realizó una encuesta (enviada vía email) a extensionistas del INTA, ProHuerta y de la Subsecretaría de Agricultura Familiar. Los resultados de esta investigación permitieron aportar, a partir del uso de herramientas estadísticas, a la descripción del perfil de los extensionistas rurales que trabajan en la Argentina, así como a la del perfil diferencial de hombres y mujeres y de quienes trabajan en las diferentes instituciones

Formación y determinación del valor del suelo: confrontación y discrepancias entre mecanismos de mercado y regulaciones administrativas

La determinación del valor del suelo implicado en los procesos de urbanización se mueve en una compleja dialéctica en la que algunos fenómenos de naturaleza morfológica como el modelado del espacio social, o el que se deduce de las determinaciones del planeamiento (aprovechamiento especialmente) se enfrentan a instrumentos de regulación que se rigen por normas de carácter administrativo (urbanísticas y expropiatorias, fiscales, financieras-hipotecarias etc.). En ese marco en el que las discrepancias son frecuentes se pretende analizar las posibles actuaciones encaminadas a influir sobre la formación de ese valor en el sentido de limitar las expectativas de aprovechamiento tradicionalmente vinculadas al sistema urbanístico establecido, destacando al respecto la implantación de criterios de sostenibilidad y participación ciudadana, así como que la utilización de normas administrativas de valoración con la finalidad de reducir tales expectativas y tratar de influir sobre el sistema urbanístico en su conjunto, no se considera suficiente para conseguir el logro de tales objetivos. Añadiendo, respecto del conjunto de normas administrativas de determinación del valor del suelo, que si bien las reglas urbanísticas y expropiatorias establecen actualmente reglas objetivas de valoración, a través de la normativa de valoración destinada a entidades financieras, o de carácter fiscal, se introducen criterios subjetivos que tratan de aproximarse al mercado, incluso en el caso del valor catastral, estructuralmente reglado. Esta separación de criterios ha llevado a un enfrentamiento al que ha venido a dar respuesta la reciente sentencia del Tribunal Supremo de 30 de mayo de 2014, que impone los criterios urbanísticos de consideración de situaciones básicas de suelo, frente a los fiscalmente regulados en relación con la normativa catastral en cuanto a la consideración de suelo urbanizable sin desarrollar, que pasa a ser considerado como en situación rural, siendo por tanto aplicables sobre el mismo las reglas de valoración que la normativa catastral establece para esta categoría de suelo (rústico) que no considera, incluso con la posterior modificación, de junio de 2015, incorporada para adaptarse a la mencionada sentencia, expectativas de aprovechamiento. Pero como se ha señalado, la exclusiva utilización de la normativa urbanística de valoración no se considera suficiente para evitar los efectos que sobre el valor de suelo produce la asignación de tales aprovechamientos, por lo que acuerdo con la actual legislación de suelo, deben asimismo potenciarse actuaciones encaminadas a un desarrollo sostenible así como a la participación ciudadana, la transparencia y el control, con la finalidad de lograr un mayor rigor en la utilización del suelo que ha de traducirse en su valoración. ABSTRACT Determining the land value involved in the urbanisation process implies a complex dialectic in which certain morphological natural phenomena like the modelling of social space or that deduced from planning determinations (especially land use) face regulatory instruments governed by administrative norms (urban planning and expropriator, tax, financial-mortgage etc.). In this context where discrepancies are common, the purpose is to analyse the possible actions geared to influence the formation of that value in the sense of limiting land use expectations traditionally linked to the established urban planning system, highlighting the implementation of sustainability criteria and citizen participation, as well as to consider that the administrative standards of evaluation for reducing said expectations, and trying to influence the urban system as a whole, are not considered sufficient for achieving these objectives. We might add, with respect to the set of administrative norms for determining the land value, that while urban and expropriations norms currently provide objective rules of valuation, subjective criteria are introduced trying to approach the market, including the structurally regulated cadastral value through valuation rules aimed at financial or fiscal institutions. This separation of criteria has led to a confrontation to which the recent ruling of the Supreme Court of May 30, 2014 responds. The aforementioned judgement imposes the urban core criteria for basic land use situations against those fiscally regulated in relation to cadastral regulations regarding the consideration of undeveloped building land, which is considered to be in a rural situation, making it subject to the same rules that cadastral valuation norms established for this category of land use (rustic) which do not consider, even with the subsequent amendment of June 2015, introduced to fit that judgment, use expectations. But as noted, the exclusive use of valuation planning regulations is not considered sufficient to avoid the effects on the land value produced by the allocation of said uses, so that according to the current land use legislation, actions aimed at sustainable development as well as citizen participation, transparency and control, shall be enhanced in order to achieve greater rigor in the use of land which should be translated in their valuation.
