1. Conservation system improves soil microbial quality and increases soybean yield in the Northeastern Cerrado
ABSTRACT The conservation tillage systems is based on the surface protection by crop residue and reduced soil disturbance. These two principles can favor the soil quality and promote sustainable agricultural systems. The study was developed with the objective of measure soil microbial biomass, soil basal respiration, enzymatic activity and soybean yield in c

2. Can implant surfaces affect implant stability during osseointegration? A randomized clinical trial
Abstract This randomized clinical trial evaluated the insertion torque (IT), primary, and secondary stability of dental implants with different surface treatments during the osseointegration period. Nineteen patients with bilateral partial edentulism in the posterior mandibular region were randomly allocated to two implant brand groups and received implants

3. Body composition, resting energy expenditure and inflammatory markers: impact in users of depot medroxyprogesterone acetate after 12 months follow-up
ABSTRACT Objective The aim of this study was to evaluate for 12 months the changes of body weight using Depot Medroxyprogesterone Acetate (DMPA) and if these changes are related to inflammatory markers. Subjects and methods Twenty women of childbearing age who chose the DMPA, without previous use of this method, BMI < 30 kg/m2, and 17 women using IUD TCu

4. Agroforestry systems, nutrients in litter and microbial activity in soils cultivated with coffee at high altitude
Agroforestry systems are an alternative option for sustainable production management. These systems contain trees that absorb nutrients from deeper layers of the soil and leaf litter that help improve the soil quality of the rough terrain in high altitude areas, which are areas extremely susceptible to environmental degradation. The aim of this study was to

5. Measures of the interannual marine variability on southeast Brazilian bight and its relationship to the spawning areas of Brazilian sardine (Sardinella braziliensis) / Medidas da variabilidade interanual marinha sobre a plataforma continental sudeste do Brasil e sua relação com áreas de desova da sardinha-verdadeira (sardinella brasiliensis)
This work aims to investigate the relation of marine interannual variability in a region located in southern coast of Brazil, also known as the Southeast Brazilian Bight (SBB) and the spawning areas of the Brazilian sardine (Sardinella braziliensis) in SBB. SBB marine ecosystems are related to a strong influence of a coastal upwelling system. Variables used

6. Arithmetic fuchsian groups identified in quaternion orders for the construction of signal constellations / Grupos fuchsianos aritmeticos identificados em ordens dos quaternios para construção de constelações de sinais
Within the context of digital communications system in homogeneous space in particular, in hyperbolic spaces, it is necessary to establish systematic procedure for the construction of lattices O ; as the basic entity for construction of eometrically uniforms signal constellations. By this procedure we identify the algebraic and geometric structures to constr

7. Viral hepatitis in patients infected with human immunodeficiency virus
From 1992 to 1995 we studied 232 (69% male, 87% Caucasian) anti-human immunodeficiency virus (anti-HIV) positive Brazilian patients, through a questionnaire; HIV had been acquired sexually by 50%, from blood by 32%, sexually and/or from blood by 16.4% and by an unknown route by 1.7%. Intravenous drug use was reported by 29%; it was the most important risk fa

8. Esclerose multipla : correlação clinica, liquido cefalorraquiano e neuroimagem
Multiple sclerosis (MS) is a chronic disease of the central nervous system (CNS) of unknown aetiology, which first manifestations occur in adolescence or in young adulthood, after multifocal demyelination caused by an autoimmune and inflammatory process. The clinical evolutive sequence can take the relapsing-remitting, secondarily progressive and primary pro

9. Assessing Phytoplankton and Bacterioplankton Production During Early Spring in Lake Erken, Sweden
The spring development of both phytoplankton and bacterioplankton was investigated between 18 April and 7 May 1983 in mesotrophic Lake Erken, Sweden. By using the lake as a batch culture, our aim was to estimate, via different methods, the production of phytoplankton and bacterioplankton in the lake and to compare these production estimates with the actual i

10. Effect of chronic airflow limitation on resting oxygen consumption.
The work of breathing in patients with severe chronic airflow limitation is increased even at rest but little is known about the magnitude of this increase. Resting oxygen consumption (VO2), carbon dioxide production (VCO2), and respiratory quotient (RQ) were measured in 13 patients with severe chronic airflow limitation (mean FEV1 0.78 1, vital capacity 2.1
