Tolerância de ovinos ao hidróxido de sódio e/ou sódio residual contido em cama de frangos de corte.
Resumo: Foram utilizados 18 ovinos da raca Corriedale, num delineamento em blocos inteiramente casualizados, com um arranjo fatorial 2 x 3, dois tipos de cama de frangos de corte, cama de casca de arroz (CCA) e cama de palha de arroz (CPA) e tres niveis de NaOH (zero, 6% e 12%). O consumo de sodio, consumo de agua, producao urinaria e a relacao de Na: Kurinaria foram significativamente (P0,05). O pH da urina mostrou tendencia a se elevar somente a medida que foram aumentados os niveis de alcali na dieta dos animais. O pH ruminal parece nao ter sido afetado pelo consumo das dietas tratadas com NaOH. O balanco de sodio foi negativo e inversamente relacionado com o consumo deste mineral, nao havendo dados suficientes que permitam a explicacao deste fato. [Sheep tolerance to sociu hydroxide and/or residual contents in the broiler litter]. Sheep tolerance to sodium hydroxide (NaOH) treated diets was studied. Eighteen Corriedale sheep were used in a completely randomized block design, witha 2 x 3 factorial arrangement. The design included two types of brolier litter lone composed of rice huiis and the other one of rice straw) and three leveis of NaOH (zero, 6% and 12%). Water and Na intakes, urine excretion and Na: K urinary ratio, increased (P 0.05) when yield increased. The urine pH showed only a tendency of increasing when the alkaii treatment in the animal diet increased. No effect of the NaOH treatments on the ruminal pH was detected. Sodium balance was negative and inversely related to the Na intake. However, there were not enough data fora ciear explanation of this fact
Group Theory analysis of phonons in two-dimensional Transition Metal Dichalcogenides
Transition metal dichalcogenides (TMDCs) have emerged as a new two
dimensional materials field since the monolayer and few-layer limits show
different properties when compared to each other and to their respective bulk
materials. For example, in some cases when the bulk material is exfoliated down
to a monolayer, an indirect-to-direct band gap in the visible range is
observed. The number of layers ( even or odd) drives changes in space
group symmetry that are reflected in the optical properties. The understanding
of the space group symmetry as a function of the number of layers is therefore
important for the correct interpretation of the experimental data. Here we
present a thorough group theory study of the symmetry aspects relevant to
optical and spectroscopic analysis, for the most common polytypes of TMDCs,
i.e. , and , as a function of the number of layers. Real space
symmetries, the group of the wave vectors, the relevance of inversion symmetry,
irreducible representations of the vibrational modes, optical selection rules
and Raman tensors are discussed.Comment: 32 pages, 4 figure

The two-echelon capacitated vehicle routing problem: models and math-based heuristics
Multiechelon distribution systems are quite common in supply-chain and logistics. They are used by public administrations in their transportation and traffic planning strategies, as well as by companies, to model own distribution systems. In the literature, most of the studies address issues relating to the movement of flows throughout the system from their origins to their final destinations. Another recent trend is to focus on the management of the vehicle fleets required to provide transportation among different echelons. The aim of this paper is twofold. First, it introduces the family of two-echelon vehicle routing problems (VRPs), a term that broadly covers such settings, where the delivery from one or more depots to customers is managed by routing and consolidating freight through intermediate depots. Second, it considers in detail the basic version of two-echelon VRPs, the two-echelon capacitated VRP, which is an extension of the classical VRP in which the delivery is compulsorily delivered through intermediate depots, named satellites. A mathematical model for two-echelon capacitated VRP, some valid inequalities, and two math-heuristics based on the model are presented. Computational results of up to 50 customers and four satellites show the effectiveness of the methods developed
CORRELATION BETWEEN FUNCTIONAL CLASSIFICATION AND KINEMATICAL VARIABLES IN ELITE WHEELCHAIR RUGBY PLAYERS
Wheelchair rugby is a
Paralympic team sport for athletes with disabilities affecting the four limbs. Players are classified according to their functional level from 0.5 (lowest function) to 3.5 (highest function). A player’s classification is based on muscle tests designed to evaluate the strength and range of motion of the upper limbs and trunk and also includes observation of the athlete on court (IWRF, 2008). Although the sport class is based on movement potential associated with neuromuscular function and performance of tasks related to the sport, it is not well known how functional classification in rugby correlates with variables strongly related to performance such as distance covered. In a previous investigation (Sarro et al., 2010), kinematical variables were analyzed in an international rugby competition and suggested a relation between functional classification and distance covered during the game. To further examine this relationship, this project aimed to investigate the correlation between functional classification and player physical performance as measured by distance covered during a game. In addition, the correlation was examined for each game quarter and as a function of velocity range
