Genetic Analyses of Growth, Carcass and Meat Quality Traits in Maternal Lines of Rabbits and Their Diallel Cross/ Análisis Genético de Caracteres de Crecimiento, Matadero y Calidad de Carne en Lineas Maternales de Conejo y en su Cruzamiento Dialélico

El gazapo engordado en explotaciones comerciales proviene de un cruzamiento a tres vías, y por tanto su madre (cruce de dos líneas maternales) aporta el 50% de sus genes y es necesario estudiar los caracteres de crecimiento y consumo de pienso de estos gazapos. Por otro lado, existen gran cantidad de estudios que demuestran que la carne de conejo es una carne con poca grasa, poco colesterol y un elevado contenido en proteina, por lo que se debe estudiar estas características se pueden ver afectadas estas como consecuencia de la mejora genética.Mínguez Balaguer, C.

Optimal sampling pattern for free final time linear quadratic regulator: the scalar case

The optimal sampling problem is the selection of the optimal sampling instants together with the optimal control actions such that a given cost function is minimized. In this article we solve the optimal sampling problem for free final time linear quadratic regulator with scalar dynamical system. The solution provides the optimal sampling instants, control actions, and the optimal final time in a recursive and constructive way for any arbitrary number of samples N ≥ 1, as it is not based on asymptotic arguments. An application example shows the feasibility of the approach

Implementación de un método C.N. trapezoidal de volúmenes finitos para la simulación numérica del proceso de migración unidimensional de una cadena radiactiva

Se ha simulado el proceso de transporte unidimensional en la geosfera de sustancias radiactivas mediante un esquema numérico basado en el método de volúmenes finitos y el esquema de Crank-Nicolson. Se ha efectuado un estudio del comportamiento del esquema en casos en los que domina el fenómeno convectivo, comparando con las soluciones obtenidas con un código numérico basado en una combinación del método de características y diferencias finitas.It has simulated the onedimensional radiactive substances transport process runing in the geosphere by a numerical scheme that is based on the finite volume method and the Crank- Nicolson scheme. A study of the scheme behaviour has been carry out for advection dominate cases, comparing with the solutions obtained by a numerical code based on a combination of characteristics and finite diference methods.Peer Reviewe

Immediate bleeding complications in dental implants: a systematic review

Objective: A review is made of the immediate or immediate postoperative bleeding complications in dental implants, with a view to identifying the areas of greatest bleeding risk, the causes of bleeding, the length of the implants associated with bleeding, the most frequently implicated blood vessels, and the treatments used to resolve these complications. Material and Methods: A Medline (PubMed) and Embase search was made of articles on immediate bleeding complications in dental implants published in English up until May 2014. Inclusion criteria: studies in humans subjects with severe bleeding immediately secondary to implant placement, which reported the time until the hemorrhage, the implant lenght, the possible cause of bleeding and the treatment. Exclusion criteria: patients receiving anticoagulation treatment. Results: Fifteen articles met the inclusion criteria. The area with the largest number of bleeding complications corresponded to the mandibular canine. The cause of bleeding was lingual cortical bone perforation during implant placement, with damage to the sublingual artery. The implants associated with bleeding were those measuring 15 mm in length or more. Management focused on securing the airway (with intubation or tracheostomy if necessary), with bleeding control. Conclusions: It’s important to pay special attention when the implants are placed in the mandibular anterior zone, especially if long implants are used. The most frequently cause of bleeding was the perforation of the lingual plate. Treatment involves securing the airway, with bleeding contro

Effect of equine chorionic gonadotropin on pregnancy rate in Brown Swiss cows under high altitude conditions

The objective of the present study was to evaluate the administration of Equine Chorionic Gonadotropin (eCG) in a protocol of fixed-time artificial insemination (FTAI) to increase the pregnancy rate in cows subjected to high altitude conditions. These conditions could generate a syndrome of right-sided heart failure and, as consequence, animals trend to have a low body score condition with a decrease in fertility. The research was conducted with 84 lactating cows (Brown Swiss) randomly into two groups with a body condition score between 2.5 and 3.5, allocated at 3100 m above sea level. In the FTAI protocol, 400 IU of eCG was administered (n = 42) or not (n = 42) at progesterone intravaginal device removal. A significant improvement in pregnancy rate was found with eCG treatment in those cows with low body condition score (BCS of 2.5, scale 1–5), while no effect was found in those cows with higher BCS (i.e. 3.0 and 3.5). In conclusion, the addition of 400 IU of eCG in an FTAI in cows under high altitude conditions and low body conditions can improve the fertility.Veterinari
