Retrospective evaluation of all recorded horse race starts in Switzerland during a four-year period focusing on discipline specific risk factors for clinical events

REASONS FOR PERFORMING THE STUDY: Racetrack injuries are of welfare concern and prevention of injuries is an important goal in many racing jurisdictions. Over the years this has led to more detailed recording of clinical events on racecourses. However, risk factor analyses of clinical events at race meetings have never been reported for Switzerland OBJECTIVE: To identify discipline-specific factors that influence the occurrence of clinical events during race meetings with the ultimate aim to improve the monitoring and safety on racetracks in Switzerland and optimise racehorse welfare. STUDY DESIGN: Retrospective study of horse race data collected by the Swiss horse racing association. METHODS: All race starts (n = 17,670, including 6,198 flat, 1,257 obstacle and 10,215 trot race starts) recorded over a period of four years (2009-2012) were analysed in multivariable mixed effect logistic regression models including horse and racecourse related data. The models were designed to identify discipline specific factors influencing the occurrence of clinical events on racecourses in Switzerland. RESULTS: Factors influencing the risk of clinical events during races were different for each discipline. The risk of a clinical event in trot racing was lower for racing on a Porphyre-sand track than on grass tracks. Horses whose driver was also their trainer had an approximately two times higher risk for clinical events. In obstacle races, longer distances (2401-3300 m and 3301-5400 m respectively) had a protective effect compared to racing over shorter distances. In flat racing, five racecourses reported significantly less clinical events. In all three disciplines, finishing 8th place or later was associated with clinical events. CONCLUSIONS: Changes in management that aim to improve the safety and welfare of racehorses, such as racetrack adaptations, need to be individualised for each discipline.

Relationship between parental feeding practices and weight status in a lower socioeconomic pre-school population

High prevalence of overweight and obesity among preschool children in the low income population is consistently documented in research with one of every seven low-income, preschool-aged children classified as obese. Parental feeding practices have the potential to be contributing factors to the obesity epidemic. However, the impact of parental feeding practices on obesity in preschool age children has not been well explored. The purpose of this study was to determine relationships between the parental feeding practices of using dessert, sweets or candy as a reward for finishing foods, restricting dessert if the child does not finish their plate at dinner, asking the child to consume everything on their plate at dinner, and having family dinners to obesity in low income, preschool age children.^ A cross-sectional secondary data analysis was completed using the STATA 11 statistical software. Descriptive statistics were completed to summarize demographic and BMI data of participants, as well as parental feeding behavior variables. Pearson’s correlation was implemented to determine a correlation between parental feeding behavior variables and BMI z scores. Predictive relationships between the variables were explored through multivariable linear regression analysis. Regression analyses were also completed factoring in the confounders of gender, age, and ethnicity.^ Results revealed (1) no significant correlations or predictive trends between the use of rewards, forced consumption, or family dinner and BMI in low income preschool age children, and (2) a significant negative correlation and predictive trend between restriction of desserts and BMI in low income preschool age children. Since the analysis supported the null hypothesis for the practices of reward use, forced consumption, and family dinner, these practices are not considered risk factors for obese level BMIs. The inverse association found for practice of restriction and BMI suggests it is unnecessary to discourage parents from using restriction. Limitations of the study included the sample size, reliability of the answers provided on the Healthy Home Survey by participant guardians, and generalizability of the sample to the larger population.^

The University Compost Facility after Three Years

The University Compost Facility, 52274 260th St., Ames, Iowa has completed three full years of operation. The facility is managed by the ISU Research Farms and has a separate revolving account that receives fees and sales, and pays expenses. The facility is designed to be self-supporting, i.e. not receive allocations for its operations. The facility consists of seven, 80 × 140 ft hoop barns and a new 55 × 120 ft hoop barn, all with paved floors. The facility also has a Mettler-Toledo electronic scale with a 10 ft × 70 ft platform to weigh all materials. Key machinery is 1) compost turner, a used pull-type Aeromaster PT-170, 14 ft wide made by Midwest Biosystems, Tampico, IL; 2) a converted dump truck trailer used to construct windrows and haul material; 3) telehandler, Caterpillar TH407 with cab and 2.75 cubic yard bucket; and 4) tractor, John Deere 7520 (125 hp) with IVT (Infinite Variable Transmission) and front-wheel assist used to pull the turner and dump trailer.

Effects of Bedding on Pig Performance

More pigs are being produced in bedded systems such as hoop barns due to the increase in demand for niche pork. Most of the current swine nutrition information has been generated in confinement settings without bedding. As omnivores, pigs ingest some bedding. There are questions about the effects of the ingested bedding on growth and feed utilization by the modern market pig. More knowledge in this area will allow for more accurate feed formulation in bedded systems.

Rentabilidad del engorde a corral de bovinos de carne en la provincia de Mendoza, Argentina

Se determinó la rentabilidad del feedlot bajo distintos escenarios productivos y económicos para la situación de precios del ganado vigentes en 2009 y 2010. La información básica provino de encuestas en feedlots, entrevistas con informantes clave y consulta bibliográfica. La tasa interna de retorno y el valor actual neto se estimaron considerando un costo de oportunidad del capital del 12% anual. El capital total varió en función de la adquisición total o producción parcial de alimentos para el ganado. Los ingresos para 3.000 animales año-1 se incrementaron 50% en 2010 respecto de 2009. Durante 2009, sin compensaciones, no existió rentabilidad al adquirir los alimentos. Se obtuvo rentabilidad sin compensaciones con aumentos del 5, 10 y 15% en inversiones y gastos operativos con producciones de 4.466, 6.214 y 9.670 animales año-1, respectivamente, al adquirir el alimento y con 2.110, 2.430 y 2.880 animales año-1 con producción del mismo. Los precios de la hacienda de 2010 con respecto a los de 2009 aumentaron la rentabilidad tanto al adquirir como al producir alimentos sin dependencia del cobro de compensaciones. Con 2.300 y 1.500 animales año-1 para las situaciones de alimento adquirido y producido, respectivamente, se alcanza rentabilidad con los precios del ganado de 2010. Se comprobó la hipótesis que la rentabilidad depende de la escala productiva y su interrelación con los escenarios contemplados.

Hacia una aproximación multidimensional e innovadora de los pilares de la orientación vocacional

Se estudian cuestiones relativas a la elección de una carrera universitaria por alumnos que finalizan la educación secundaria. La hipótesis es que una complementación de enfoques que recupere dimensiones presentes en la teoría y en los instrumentos derivados, algunos de vieja data, permite anticipar una elección profesional satisfactoria. El objetivo general es analizar la viabilidad de conjugar principios y recursos de diferente origen psicológico-epistemológico, en una perspectiva holística y con proyección al plano aplicado. Para alcanzarlo se abordan cuali y cuantitativamente: intereses vocacionales y personalidad, globalmente considerados (variables independientes) en su relación con la elección de una carrera y se estima la capacidad de anticipar “una buena elección", medida por permanencia en la carrera, satisfacción y convicción de que se la volvería a elegir (variables dependientes). La fuente son registros documentales de procesos de Orientación y una entrevista de seguimiento habiendo transcurrido entre dos y seis años desde la elección. Es un estudio descriptivo, comparativo y en algunas instancias analiza correspondencias. Los resultados corroboran que la complementación de perspectivas e instrumentos sustenta una decisión vocacional que se caracteriza por la satisfacción con la elección, la permanencia en la carrera y la convicción de que se la volvería a elegir. Como corolario se resignifica la conceptualización de Orientación Vocacional sobre bases etimológicas y empíricas, en tanto proceso que realiza “quien se orienta" en cierta dirección.

Edouard Glissant e o legado de William Faulkner

Este trabajo se propone analizar el intertexto que une al escritor Edouard Glissant con William Faulkner a través de dos obras: el ensayo Faulkner, Mississipi (1996) y la novela Sartorius (1999). En el primer texto, el autor enfatiza cuestiones presentes en su propia obra novelesca: la genealogía, la relación con el espacio de la plantación, el mestizaje, la (i)legitimidad de derechos con respecto a la posesión de la tierra, la opacidad. En el segundo, traza una línea genealógica de un personaje perteneciente a una etnia africana imaginaria, haciéndolo llegar hasta las plantaciones del sur de los Estados Unidos; paralelamente, presenta la línea genealógica de los Sartoris. En esta dirección, busco mostrar cómo el proyecto literario de Glissant dialoga con la obra de Faulkner, indagando e inventariando las mismas problemáticas con respecto al transplante de poblaciones y su inserción en el espacio de las plantaciones, tanto en el sur de los Estados Unidos como en las islas del Caribe. En las obras de ambos escritores puede percibirse el mismo vértigo trágico que persigue a los personajes, conduciéndolos a la locura, el sufrimiento y la muerte

Qualidade de sementes de algodâo submetidas aos procesos de encapsulamento com e sem corante

Objetivou-se estudar a qualidade fisiológica de sementes de algodão quando submetidas aos processos de encapsulamento com e sem corante em comparação com as sementes apenas tratadas com fungicidas (carboxin e thiran 200 Sc) e inseticida (pirimiphos methyl) - testemunha. A betoneira grande (capacidade de 40 L) recebeu sementes deslintadas + tratadas para serem submetidas ao processo de encapsulação (coating e finishing) com e sem corante, além de uma testemunha não encapsulada, estabelecendo-se os seguintes tratamentos: 1- sementes deslintadas e tratadas com fungicidas (carboxin e thiran 200 Sc) e inseticidas (pirimiphos methyl) (testemunha); 2- sementes deslintadas, tratadas e encapsuladas (coating e finishing) sem corante; e 3- sementes deslintadas, tratadas e encapsuladas com corante. Foi adotado o delineamento inteiramente casualizado com três tratamentos e quatro repetições. As variáveis analisadas foram percentagem de germinação, comprimento de plântulas e massa de 100 sementes. Observou-se que o processo de recobrimento de sementes de algodão deslintadas, tratadas com fungicidas e inseticida e encapsuladas não ocasiona redução na qualidade fisiológica das sementes, e o uso de corante em sementes encapsuladas não altera a sua qualidade.

An educational initiative between the Universidad Politécnica de Madrid and Spanish Young Generation in Nuclear (Jóvenes Nucleares): The Seminar of Nuclear Safety in Advanced Reactors

Jóvenes Nucleares (Spanish Young Generation in Nuclear, JJNN) is a non-profit organization and a commission of the Spanish Nuclear Society (SNE). The Universidad Politécnica de Madrid (Technical University of Madrid, UPM) is one of the most prestigious technical universities of Spain, and has a very strong curriculum in nuclear engineering training and research. Finishing 2009, JJNN and the UPM started to plan a new and first-of-a-kind Seminar in Nuclear Safety focused on the Advanced Reactors (Generation III, III+ and IV). The scope was to make a general description of the safety in the new reactors, comparing them with the built Generation II reactors from a technical point of view but simple and without the need of strong background in nuclear engineering to try to be interesting for the most number of people possible.

Service needs forecasting: an approach for the automotive industry using analogies with medical ER management models.

During the past years, the industry has shifted position and moved towards “the luxury universe” whose customers are demanding, treating individuals as unique and valued customer for the business, offering vehicles produced with the state of the art technologies and implementing the highest finishing standards. Due to the competitive level in the market, car makers enable processes which equalizes customer services to E.R. management, being dealt with the maximum urgency that allows the comparison between both, car workshops and emergency rooms, where workshop bays or ramps will be equal to emergency boxes and skilled technicians are equivalent to the health care specialist, who will carry out tests and checks prior to afford any final operation, keeping the “patient” under control before it is back to normal utilization. This paper establishes a valid model for the automotive industry to estimate customer service demand forecasting under variable demand conditions using analogies with patient demand models used for the medical ER.

Estudio de la influencia del sistema de referencia en la evaluación de parámetros de acabado superficial

In the present paper the influence of the reference system with regard to the characterization of the surface finishing is analyzed. The effect of the reference system’s choice on the most representative surface finishing parameters (e.g. roughness average Ra and root mean square values Rq) is studied. The study can also be applied to their equivalent parameters in waviness and primary profiles. Based on ISO and ASME standards, three different types of regression lines (central, mean and orthogonal) are theoretically and experimentally analyzed, identifying the validity and applicability fields of each one depending on profile’s geometry

Multi-criteria selection of structural adhesives to bond ABS parts obtained by rapid prototyping

One of the most used methods in rapidprototyping is Fused Deposition Modeling (FDM), which provides components with a reasonable strength in plastic materials such as ABS and has a low environmental impact. However, the FDM process exhibits low levels of surface finishing, difficulty in getting complex and/or small geometries and low consistency in “slim” elements of the parts. Furthermore, “cantilever” elements need large material structures to be supported. The solution of these deficiencies requires a comprehensive review of the three-dimensional part design to enhance advantages and performances of FDM and reduce their constraints. As a key feature of this redesign a novel method of construction by assembling parts with structuraladhesive joints is proposed. These adhesive joints should be designed specifically to fit the plastic substrate and the FDM manufacturing technology. To achieve this, the most suitable structuraladhesiveselection is firstly required. Therefore, the present work analyzes five different families of adhesives (cyanoacrylate, polyurethane, epoxy, acrylic and silicone), and, by means of the application of technical multi-criteria decision analysis based on the analytic hierarchy process (AHP), to select the structuraladhesive that better conjugates mechanical benefits and adaptation to the FDM manufacturing process
