1. Assessment of Trace Element Contents in Soils and Water from Cerrado Wetlands, Triângulo Mineiro Region
ABSTRACT In the Brazilian Cerrado biome, there are wetlands locally known as “Veredas”, which are swampy plains between hills and rivers. Since the 1970’s, the Cerrado biome has been gradually converted to livestock, crop, or forestry production. Until now, very few studies were conducted to evaluate the baseline contents of trace elements in Cerrado w

2. Effects of feed restriction and forage:concentrate ratio on digestibility, methane emission, and energy utilization by goats
ABSTRACT This study was carried out to to evaluate how feed restriction and different forage:concentrate ratios affect digestibility, methane emission (using the SF6 technique), and energy utilization of Anglo-Nubian goats. Fifteen (15) dry and non-pregnant Anglo Nubian goats, averaging 30±2.9 kg body weight, were used. The experiment was divided into two t

3. Estudo de compostos orgânicos voláteis na atmosfera da região metropolitana de Campinas / Study of volatile organic compounds in the atmosphere of metropolitan area of Campinas
This work presents a study of volatile organic compounds (VOC) found in the atmosphere of Metropolitan Area of Campinas (Campinas, SP). The first step was to perform a vehicular emissions inventory of the study area. Vehicular emissions were estimated using emission factors from new vehicles and bottom-up approach, considering different categories of vehicle

4. Sustainable business: the concept of governance change - application a company in the petrochemical / Sustentabilidade empresarial: o conceito da governança climática aplicação a uma empresa do ramo de petroquímica
With vital significance, the greenhouse effect gases (GEG), as carbon dioxide and methane, among others, retain sun heat in the atmosphere. This fact avoids sun radiation from dissipating, without letting the Planet being warm enough to keep right conditions for live existence of Earth. However, mankind activities are increasing concentration of these gases

6. Estudo comparativo das emissões de aldeídos originados pelo veículo à diesel com o uso do óleo diesel comercial, biodiesel e suas misturas / Comparative study of aldehyde emissions generated by Diesel vehicles using of commercial diesel fuel, biodiesel and their mixtures
Since of the automotive diesel fuel contains 2% biodiesel and there exists no regulation of emissions of aldehydes of Diesel cycle vehicles, this paper aims to evaluate the emissions of aldehydes of such a category of vehicles, using diesel oil with 2% biodiesel (B2) and 100% soybean biodiesel (B100) as fuel. It also aims to evaluate the emissions of aldehyd

7. Inventário de emissões atmosféricas e avaliação de condicionantes meteorológicas: estudo de caso de Três Lagoas / Inventory of atmosferic emissions and meteorological conditionates: studies of Três Lagoas
Desde a década de 1930 distintos estudos têm fortemente aumentado o conhecimento acerca da atmosfera da Terra. De fato, nos últimos trinta anos, devido ao intenso avanço científico e tecnológico um progresso real ocorreu nesta área; incluindo os efeitos da poluição do ar. No entanto, os efeitos da poluição do ar, principalmente em regiões urbanas

8. Transcranial magnetic stimulation efficiency in patients with tinnitus and normal pure-tone audiometry: clinical and neuroimaging evaluation. / Eficácia da estimulação magnética transcraniana em pacientes com zumbido e audiometria normal: avaliação clínica e por neuroimagem
INTRODUCTION: Tinnitus is a frequent disorder which is very difficult to treat. There is compelling evidence that tinnitus is associated with functional alterations in the central nervous system. Recently, the targeted modulation of tinnitus-related cortical activity through repetitive transcranial magnetic stimulation (rTMS) has been proposed as a promising

12. Inventario de emissões de dioxido de carbono devido ao uso de energia : a região de Campinas e seu setor sucro-alcooleiro
The environment and its conservation have been the focus of public and scientific attention since the last decade. The greenhouse effect, its causes and consequences are topics of current interest. The attempt to determine the human contribution to this effect demands the accounting of greenhouse gas emissions, mainly CO2, the atmospheric concentration of wh
