Currently the mobile services represent an essential tool in daily life of the population. However, while offering greater convenience to its users, there is growing concern about the harmful effects to human health, derived from daily exposure of the public to electromagnetic fields from radio base stations (RBS), since even today, there is no study proving that longterm exposure to low-level fields are not harmful to health. In Presidente Prudente has not been a study reporting values of measurements of electromagnetic fields from base stations installed in the city. Based on these data, this study aimed to assess the levels of electromagnetic exposure in the city of Presidente Prudente regarding recommended by international bodies, as well as propose measures that can reduce public exposure to electromagnetic fields. For measuring values of electromagnetic fields, we used appliance Electromagnetic Field Meter Portable Digital - DRE-050, the Instrutherm, following the methodology suggested and adapted from the Adilza Condessa Dode’study. In total, 49 points were mapped corresponding to the areas at risk of exposure to electromagnetic fields generated by the substations of power grid, transmission towers and telecommunication towers located in the city of Presidente Prudente (SP)

Lasertherapy is a method of non-pharmacological treatment and surgery that can be used in several injuries and in various tissues, from bone fractures to tendonitis, skin wounds and damaged nerves, permitting the recovery of these structures and their functions without causing any side effects. Laser therapy aims to restore patients that suffered various injuries, such as bone fracture, inflammation, edema, tendon rupture, spinal cord injury, among others, without invasive intervention, and the results obtained in several studies and case reports have proven the high potential of this therapy to become an official treatment of various pathological changes

O presente estudo teve como objetivo testar previsões da teoria sobre a influência da predação na evolução dos ciclos vitais. Como modelo de estudo, foram estudadas populações do peixe Poecilia vivipara que habitam o Parque Nacional da Restinga de Jurubatiba, no sistema lagunar Norte-Fluminense, estado do Rio de Janeiro. Neste sistema lagunar, P. vivipara está sujeita à predação por peixes piscívoros (e.g. a traíra Hoplias malabaricus) em parte das lagoas, mas está livre destes predadores em outras lagoas. Foram estudadas três lagoas em que P. vivipara coexiste com seus predadores piscívoros e três em que estes estão ausentes. A ictiofauna das seis lagoas foi amostrada através de redes de arrasto e espinhel. Em laboratório, as fêmeas e os machos de P. vivipara foram dissecados para remoção de suas gônadas. As gônadas das fêmeas foram categorizadas em seis diferentes estágios de desenvolvimento. A partir do terceiro estágio, os embriões foram contados e medidos (maior diâmetro). Os exemplares de P. vivipara e suas gônadas foram secos em estufa a 60ºC e pesados em balança analítica (0,01 mg). Os aspectos do ciclo vital analisados foram: (1) investimento reprodutivo das fêmeas (massa gonadal/massa total da fêmea); (2) índice gonadossomático dos machos (massa gonadal/massa total do macho); (3) fecundidade (número de embriões); (4) comprimento médio dos embriões; e (5) massa seca média dos embriões (massa gonadal/fecundidade). O efeito da predação foi testado com uma ANCOVA aninhada, com regime de predação (alta intensidade, baixa intensidade), população de origem (aninhada dentro do regime de predação) e coleta como variáveis independentes, e massa somática e estágio embrionário como covariáveis. De acordo com o previsto pela teoria, as fêmeas dos ambientes de baixa predação apresentaram embriões maiores, mas, contrariando as previsões teóricas, também apresentaram maior fecundidade e...

This study is a theoretical investigation which intends to discuss possible relationships between work and boredom based on notable authors and theories. Unlike modern industrial societies centered mainly in production, new societies are characterized by increased consumption. The meaningless work and non-productive and prospective consumption leads the subject to be only a digestive organ providing favorable conditions for the presence of boredom, a mode of subjectivation characterized by a status of unconcern for the world, i.e. a low-intensity lifestyle.

The response of bone metabolism is directly related to hormonal factors and mechanical stimuli that the bone is exposed. The ultrasonic energy on bone healing have been shown to be crucial for the stimulation and improvement in quality of newly formed tissue. The aim of this study was to analyze the action of low intensity ultrasound on bone healing of tibial osteotomy in rats subjected to tail suspension, through histological analysis and histomorphometry. Eighteen Rattus norvegicus albinos, Wistar, adults were divided into three groups, arranged as follows: G1 (n = 6), who remained free for a period of 15 days, G2 (n = 5), suspended by the tail for a period of 15 days and G3 (n = 7), suspended by the tail for a period of 36 days. In all three groups, both tibias were subjected to mono-cortical bone injury 4X2 mm in the medial region of the diaphysis, and the left limb was used as control and the right limb undergoing treatment with ultrasound (U.S.). The right tibia was treated with pulsed ultrasound at a frequency of 1.5 MHz, duty cycle 1:4, 30mW/cm2, for 12 sessions of 20 minutes each. Samples of tibia were subjected to histological analysis, blindly, with light microscopy and histomorphometric analysis by specific software Image-Pro 6.1. The average percentage of new bone formation were subjected to analysis of variance in subdivided parcels and multiple comparison test "Student-Newman-Keuls (SNK), with a significance level of 5%. The average values and standard deviations of the percentage of newly formed bone for the groups showed the least amount of bone repair G1t (13.62% ± 4.88%) - G1c (8.68% ± 4.16%) compared G2t groups (27.17% ± 11.36%) - G2c (10.10% ± 7.90%) and G3t (23.19% ± 5.61%) - G3c (15.74% ± 7 08%). However, the mean values and standard deviations of the percentage of newly formed bone repair in the tibia treated G2t and G3t were significantly higher when compared to the repair of tibia in the control group (G2c and G3c). Consequently, we conclude that ultrasound has helped to accelerate bone repair in both the presence and absence of cargo.

Geophysical survey is an important method for investigation of contaminated areas used in the characterization of contrasting physical properties in the presence of pollutants. This work applied the geophysical methods of Electrical Resistivity and Self Potential in waste landfill, located in Caçapava do Sul city, RS. The landfill is located over fractured metamorphic rocks. Eight lines of electrical profiling with 288 measures of self potential were done. In addition, 83 measurements of direction and dip of fractures were taken. The application of spontaneous potential method permitted to detect the direction of groundwater flow. The electrical resistivity measurements allowed the identification of low-intensity anomalies associated with the presence of leachate. There is a relationship between anomalous zones and the directions of fractures.
