BACKGROUND Resuscitation guidelines recommend that chest compressions should continue throughout attempts to place airway devices. Few data support the use of the tracheal tube over supraglottic airway devices (SADs) during cardiopulmonary arrest. This study was designed to evaluate the speed with which different airway devices could be placed with and without interrupting chest compressions. ...
Adsorption isotherms and specific retention volumes of benzene on MCM41C16 mesoporous silica and F4O porous carbon were determined at different temperatures by employing inverse gas chromatography. The differential isosteric enthalpies, -∆Hads , and entropies, -∆Sads , of adsorption were calculated from the retention time data and compared with the results obtained from the adsorption second vi...
(Abundance distribution of common and rare plant species of Brazilian savannas along a seasonality gradient). We examined the species abundance distribution (SAD) of plant communities in: (1) a wet grassland, waterlogged throughout most of the year; (2) a seasonal savanna, with an annual dry season; and (3) a hyperseasonal savanna, with alternating drought and waterlogging over the year. We sea...
زمینه و هدف: همراهی اختلال بیش فعالی و نقص توجه (ADHD) و اختلال افسردگی در مطالعات بالینی و اپیدمیولوژیک در منابع بزرگسال و اطفال گزارش شده است. با بررسی خویشاوندان درجه یک بیماران ADHD، این مطالعه به منظور تعیین ارتباط با الگوهای خانوادگی همراهی بین اختلال بیش فعالی و نقص توجه و اختلال افسردگی انجام شد.روش بررسی: این مطالعه مورد شاهدی روی 208 کودک و نوجوان مبتلا به ADHD 5 تا 17 سال مورد ارزیاب...
INTRODUCTION A retrospective cohort study on Salmonella-associated diseases (SADs) was conducted in 14 public hospitals across Lagos State, Nigeria, between 1999 and 2008. METHODOLOGY Medical records of clinically diagnosed patients with confirmed Salmonella infections were reviewed for the 10-year period. Laboratory diagnosis of typhoid fever cases in all the hospitals were first based on Wi...
OBJECTIVE To compare paroxetine with placebo and imipramine with placebo for the treatment of adolescent depression. METHOD After a 7- to 14-day screening period, 275 adolescents with major depression began 8 weeks of double-blind paroxetine (20-40 mg), imipramine (gradual upward titration to 200-300 mg), or placebo. The two primary outcome measures were endpoint response (Hamilton Rating Sca...
Ecological communities are subjected to stochasticity in the form of demographic and environmental variance. Stochastic models that contain only demographic variance (neutral models) provide close quantitative fits to observed species-abundance distributions (SADs) but substantially underestimate observed temporal species-abundance fluctuations. To provide a holistic assessment of whether model...
OBJECTIVE To evaluate the global impact of adopting highest-level MPOWER tobacco control policies in different countries and territories from 2007 to 2010. METHODS Policy effect sizes based on previously-validated SimSmoke models were applied to determine the reduction in the number of smokers as a result of policy adoption during this period. Based on previous research suggesting that half o...
The semiclassical corrections to the Cardy-Verlinde entropy of a five-dimensional Schwarzschild anti de-Sitter black hole (SAdS 5) are explicitly evaluated. These corrections are considered within the context of KKW analysis and arise as a result of the self-gravitation effect. In addition, a four-dimensional timelike brane is considered as the boundary of the SAdS 5 bulk background. It is alre...
As a rule, communities consist of few abundant and many rare species, which is reflected in the characteristic shape of species abundance distributions (SADs). The processes that shape these SADs have been a longstanding problem for ecological research. Although many studies found strong negative effects of increasing land-use intensity on diversity, few reports consider land-use effects on SAD...
