the aim of the current study was to investigate three volleyball skills in three training conditions of blocked, random and serial to reveal their effects in three phases of acquisition, retention and transfer. 60 amateur male students (mean age = 21.5 years, sd= 1.2) were voluntarily selected and randomly divided into three training groups (blocked, random and serial). a pretest was used to ma...

The epidemiology of new acquisition of antibiotic-resistant organisms (AROs) in community-based skilled nursing facilities (SNFs) is not well studied. To define the incidence, persistence of, and time to new colonization with methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE), and ceftazidime-resistant (CAZ(r)) and ciprofloxacin-resistant (CIP(r)) Gram-ne...

Background Increasing attention is being focused on the influence of rapid increases in atmospheric CO2 concentration on nutrient cycling in ecosystems. An understanding of how elevated CO2 affects plant utilization and acquisition of phosphorus (P) will be critical for P management to maintain ecosystem sustainability in P-deficient regions. Scope This review focuses on the impact of elevated ...

High intensity aerobic exercise amplifies offline gains in procedural memory acquired during motor practice. This effect seems to be evident when exercise is placed immediately after acquisition, during the first stages of memory consolidation, but the importance of temporal proximity of the exercise bout used to stimulate improvements in procedural memory is unknown. The effects of three diffe...

Corpus-based activities (CBAs) have been used in FLT recent decades, especially countries where educational systems are well developed. However, this is not the case Bosnia and Herzegovina. That why a study was conducted primary school Herzegovina including 48 7th grade students divided into an experimental control group to investigate effect of use corpus-based on vocabulary acquisition. In bo...

OBJECTIVE To analyze the relationship between maternal posture/physical activity and inadequate birthweight. METHODS Prospective cohort study involving 152 pregnant women from a public low-risk antenatal care facility. Three interviews evaluating the frequency of physical activity were administered to each pregnant woman during gestation. Birthweight (inadequate when <3,000 g and adequate whe...

OBJECTIVE To determine the prevalence of excess body weight and abdominal obesity and assess the association with socioeconomic, demographic and behavioral factors among adults of Maranhão, Brazil. METHODS Multistage cluster sample investigated through a household survey on 1,005 adults aged 20 to 59 years (393 men and 612 women). Anthropometric measures: weight, height and waist circumferenc...

Scheduling tasks with precedence constraints on a set of resources with different performances is a well-known NP-complete problem, and a number of effective heuristics has been proposed to solve it. If the start time and the deadline for each specific workflow are known (for example, if a workflow starts execution according to periodic data coming from the sensors, and its execution should be ...

BACKGROUND The objectives of this study were to assess the impact among young men of herpes simplex virus type 2 (HSV-2) status on the acquisition of human immunodeficiency virus (HIV) and on the protective effect of male circumcision against HIV acquisition. METHODS We used data collected during a male circumcision trial conducted in Orange Farm, South Africa. We estimated adjusted incidence...
