Based on the concept that horses have balanced symmetry between its anatomical regions, the aim of this study was to introduce a method of assessing the balance of equines through body proportions. Altogether twelve linear measurements, using metric tape, were measured in 234 horses Quarter Horses for evidence of barrel racing. From these measurements were built nine body proportions, each one given by the ratio of two specific measures, and the effects of sex, weight, age and degree of blood on the balance were evaluated. To check the significance tests we used the F statistic, considering P<0.05. It was found that the linear measurements ML2, ML3 and ML5 were mainly responsible for the disproportionality of the horses evaluated. The effect of sex was significant (P<0.05) for four proportions (R1, R3, R4 and R9) and females were more distant from the concept of balance than males.

The objective of this study was to evaluate the supplementation of linseed as an omega-3 fatty acid supplier on the functional capacity of jumping horses. 6 horses disposed in two 3 x 3 balanced Latin squares were used. The treatments consisted of increasing levels of linseed mixed with flour and linseed oil in a ratio of 75:25, respectively, resulting in 0g (control), 60g and 120g on a daily basis per horse. The horses were supplemented for 30 days. Physical activity was jumping at riding class level. The functional parameters measured were lameness index, stride length and joint metacarpophalangeal (MCP) biometry (circumference and flexion angle). A significant linseed supplementation effect for doses of 60 and 120g was observed on the lameness index. Feeding 120g of linseed increased stride length while trotting (P<0.05). An increment of 0.5cm on MCP circumference was found in horses that received the control diet when compared to those horses that consumed 120g of linseed. Thus, supplementation of jumping horses with 120g/day of linseed promoted greater stride length at a trot and reduced swelling in the metacarpophalangeal joint, improving their functional capabilities.

Efluentes industriais e domésticos podem conter agentes químicos e biológicos que, em elevadas concentrações, causam danos aos ecossistemas aquáticos e à saúde ambiental. Um dos efeitos mais nocivos desses agentes poluidores é a sua capacidade de induzir alterações celulares. O uso de testes específicos capazes de detectar o potencial tóxico de substâncias químicas caracteriza-se em uma importante estratégia para avaliação ambiental. Neste contexto, o presente estudo teve como objetivo avaliar os potenciais citotóxico, genotóxico e mutagênico de amostras de água de recursos hídricos da cidade de Santa Gertrudes-SP, relacionada com recebimento de efluentes de atividade ceramista, por meio de ensaios realizados com o sistema-teste de Allium cepa. Foram realizados testes com amostras de água coletadas no córrego Itaqui, após despejos de efluente de indústria cerâmica e em duas nascentes, tanto em período chuvoso como de seca. Para a análise dos parâmetros de toxicidade descritos acima, sementes de A. cepa foram expostas à germinação nas amostras das águas coletadas. Quando as radículas atingiram 2 cm de comprimento, os meristemas foram fixados em solução de Carnoy 3:1, para serem utilizadas nas avaliações das possíveis alterações dos índices de germinação e mitóticos, bem como de indução de aberrações nucleares e cromossômicas. Além disso, também foram avaliadas, como outro parâmetro indicativo de mutagenicidade, as frequências de micronúcleos em células F1 de A. cepa. O controle negativo foi realizado em água (osmose reversa) e o controle positivo em metilmetanosulfonato (MMS). O material fixado foi corado pela reação de Feulgen e as lâminas foram preparadas, utilizando as porções meristemática e F1 das raízes de A. cepa. As análises foram realizadas em microscópio de luz, por meio da contagem de alterações nucleares (micronúcleos e brotos) e de aberrações cromossômicas...

This work presents a proposal to create a Polo Ceramic Craft in the town of Indiana - SP, through the potter’s organization in a cooperative that will coordinate activities to add value to ceramic pieces. To achieve this, two things are essential: improving the ceramic body and improve the properties of the ceramic material. For the first action it’s necessary to create a Central Mass Production of Ceramics, to provide raw materials and homogeneous composition that results in differentiated ceramic after burning process (sintering). To this end, we propose the incorporation of additives (which act as fluxes) to the clay material. These additives can be mineral such as feldspar and nefelinas or leavings, such as glass powder obtained from disposable containers. For the second action is necessary to acquire an oven, electric or gas, it reaches higher temperatures (around 1200 ° C). The presence of the additive and burning at higher temperatures will enable better production of sintered ceramic material with less porosity and water absorption and higher mechanical strength, and pieces vitrified and glazed, allowing them to assign a higher value. For the production of these materials (thinner walls) requires a smaller volume of clayey raw materials. Besides benefiting the ceramic pieces, the proposed changes reduce the environmental impact caused by burning wood, since it will be replaced by natural gas (or electricity), and even will reduce the disposal of glass containers in the environment by recycling and incorporating this material in the clay. From a social standpoint, the cooperative is crucial to the viability of the proposed project, to coordinate activities and commercial production, which will result in better wages and profits for companies and consequently for the city and its population

The present study aimed to analyze the performance of 'boost' among water polo athletes. Twelve athletes (13,9 1,08 years, 169,0 6,0 cm and 59,5 13,5 kg of bodyweight) were under went to anthropometric assessment, body composition and maximum concentric strength of lower limbs. The jump test in the water was done by 'boost' and scaled to jump height. According to the results of strength (Leg Press 45: 157,08 43,30 kg Leg Extension: 72,08 12,86 kg), anthropometry (arm circumf.: 26,04 3,25 cm, thigh circumf.: 50,47 7,65 cm, sholder circumf.: 95,97 8,00 cm, elbow diam.: 4,74 0,51 cm, wrist diam.: 3,21 0,34 cm, knee diam.: 7,89 0,58 cm, biacromial diam.: 37,49 3,81 cm and bi-iliac diam.: 25,43 4,34 cm) and body composition (BMI: 20,74 4,00 kg / m² and% fat: 8,45 4,28), only stature showed a linear correlation (r= 0,595) to the values of vertical jump (height: 47,80 4,35 cm) performance. This anthropometric variable was one able to influence the height of performance by modifying it self, perhaps by maturity. However maturity may be an implicity feature of performance, since force is a concerned effect of the growth. Otherwise technique could play a mains role to the performance of the 'boost'. It can be conclude that possibly is advantageous for water polo athlete be higher and more mature for the realization of 'boost', and the training directed for the technique, but is necessary muscle fitness for the holder
