Equilíbrio de cavalos da raça Quarto de Milha participantes da modalidade de três tambores por meio de proporções corporais

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.

Classificação e mapeamento de áreas de risco de enchentes e inundações no bairro Jardim Inocoop - Rio Claro - SP

In the last few decades, Brazil has experienced an accelerated urbanization process in which many cities have grown in a disorderly way occupying environmentally fragile areas unsuitable for habitation. Anthropogenic actions such as high levels of impermeable soil, structural changes in watercourses, lack of riparian vegetation, illegal presence of trash and rubbish along the river banks added to irregular settlements in floodplains result in the rise of high risk areas. When accompanied by intense and prolonged rainfall phenomena, those areas have been the scenery of serious accidents such as floods. This study aims to classify the level of the risk of floods in the neighborhood of Jardim Inocoop, in the town of Rio Claro, São Paulo countryside, Brazil. One of the main technical support to tackle this issue is the identification and classification of the risks. In order to classify the risk level of flood in this case study, the methodology adopted was developed by the Ministry of Cities and Technology Research Institute, and take into account the arrangement of the hydrological scenario, vulnerability of households and dangerous process according to the distance of the houses from the axis of drainage. Therefore, the risk levels adopted to classify are listed below: very high (MA), high risk (A), moderate (M) and low risk (B). In conclusion, it is imperative to develop prevention plans in order to avoid or to minimize the damages caused by natural disasters. Therefore, the zoning of the risk sceneries remains as an important issue once it helps to identify the areas with high level risk of flood. Consequently, the occupation must be regulated where there is low or absent risk and it must be often forbidden where the high risk of flood is detected. Thus, the present study remains as an attempt to notify the risk of floods through its spatialization on a map, remainig...(Complete abstract click electronic access below)

Morfologia e expressão dos MRF’s no músculo esquelético de ratos submetidos a estímulo atrófico e recuperação por treinamento físico

Recent research advances in understanding the cellular and molecular mechanisms that underlie the processes of hypertrophy and atrophy. This may contribute to development of effective therapeutic strategies to attenuate or block the loss of muscle tissue associated with aging and pathological conditions. In this context, myogenic factors that control the activity of satellite cells have been studied to better understand the events involved in the recovery of muscle mass. Among them, we highlight the Myogenic Regulatory Factors (MRFs), which have been described as potential mediators of muscle growth. The objectives of this study evaluated the morphofunctional adaptations and gene expression of MRFs (MyoD and myogenin) in skeletal muscle (soleus) subjected to an atrophic stimulus followed by physical training. It was used 64 male Wistar rats (80 days, 250 to 300 g), divided into 8 groups (n = 8): C: control animals a week, I: Animals immobilized a week, C3: control animals 3 days; R3: Animals immobilized and recovered for 3 days, T3: Animals immobilized and submitted to exercise for 3 days; C7: Animals controls 7 days; R7: Animals immobilized and subsequently recovered by 7 days, T7: Animals immobilized and subsequently subjected to exercise for 7 days. Initially, the animals in groups I, R3, R7, T3 and T7, were submitted to 7 days of immobilization of the hind limb. Muscle atrophy was confirmed after a direct statistical comparison of the values of cross-sectional area (CSA) of muscle fibers studied in animals in groups I and C, sacrificed immediately after the immobilization period. Then, the groups T3 and T7 were submitted a rehabilitation program with muscle aerobic exercise (swimming) for 3 and 7 days respectively. The groups C, C3 and C7 were kept without stimulus atrophic and were not subjected to exercise. At the end of the experiment, the animals were sacrified and the soleus muscle removed. The quantitative analysis of gene expression ...

Propriedades estruturais de géis de sílica preparados com adições de dodecil sulfato de sódio

This work aims to study the structural characteristics of silica gels obtained from the acid hydrolysis of tetraethoxysilane (TEOS) in water solutions with different concentrations of sodium dodecyl sulfate (SDS). The structural characteristics were studied in stages ranging from the wet gel to the dry stages of the gels (aerogels and xerogels). Aerogels were obtained by ambient pressure drying (APD) after silylation process using trimethylchlorosilane (TMCS) as silylating agent. Xerogels were obtained by conventional evaporating the liquid phase from non silylated gels. The samples were characterized by nitrogen adsorption and small angle X-ray scattering (SAXS). The structure of the wet gels and of the aerogels prepared with the surfactant exhibited characteristics of mass-fractal structures with fractal dimension D in the range 2.1-2.2 for the wet gels and 2.3-2.4 for the aerogels. The characteristic size  of the fractal domain reduces while the size a0 of the primary silica particle composing the fractal structure increases with the drying of the gels, in a process in which share of the porosity is eliminated. Aerogels exhibited typical values for the specific surface of 900 m2g-1 and of 3.5 cm3.g-1 for the total pore volume. These values are correspondingly comparable to those of the aerogels prepared by supercritical drying, since the silylation process replaces hydrophilic –OH groups by hydrophobic –Si-R3 ones, inhibiting the porosity elimination on drying. The silica particle size also increases lightly with the silylation because the attachment of the –Si-R3 groups on the silica surface. The pore size distribution curves of the aerogels are similar for all samples exhibiting a maximum in around 40 nm, independent the concentration of surfactant. This suggests that the characteristic size of 40 nm is due to the association of surfactant micelles... (Complete abstract click electronic access below)

On-plant larval movement and feeding behavior of fall armyworm (Lepidoptera: Noctuidae) on reproductive corn stages

Spodoptera frugiperda J.E. Smith (fall armyworm) is considered one of the most destructive pests of corn throughout the Americas. Although this pest has been extensively studied, little is known about its larval movement and feeding behavior on reproductive compared to vegetative corn stages. Thus, we conducted studies with two corn stages (R1 and R3) and four corn plant zones (tassel, above ear, ear zone, and below ear) in the field at Concord, NE (USA), and in the field and greenhouse at Botucatu, SP (Brazil), to investigate on-plant larval movement. The effects of different corn tissues (opened tassel, closed tassel, silk, kernel, and leaf), two feeding sequence scenarios (closed tassel-leaf-silk-kernel and leaf-silk-kernel), and artificial diet (positive control) on larval survival and development were also evaluated in the laboratory. Ear zone has a strong effect on feeding choice and survival of fall armyworm larvae regardless of reproductive corn stage. Feeding site choice is made by first-instar. Corn leaves of reproductive plants were not suitable for early instar development, but silk and kernel tissues had a positive effect on survival and development of fall armyworm larvae on reproductive stage corn.
