BACKGROUND Concomitant use of stimulants and atypical antipsychotics is common in pediatric attention deficit hyperactivity disorder (ADHD). However, little is known about the determinants of concomitant use and its utility in the management of pediatric ADHD. OBJECTIVES To (a) examine predictors of concomitant stimulant and atypical antipsychotic use and (b) evaluate the impact of concomitan...

v.23, n.1, jan.-mar. 2016, p.221-223 221 En un momento en que los derechos del parto y las denuncias de la violencia obstétrica se posicionan fuertemente en la agenda del movimiento de mujeres y de algunos feminismos, este libro viene a hablarnos de las representaciones de la maternidad y sus circulaciones en la Argentina del siglo pasado, cuando algunas de estas formas de control social sobre ...

Linear alkylbenzene sulfonate (LAS) is widely used in the formulation of domestic and industrial cleaning products, the most synthetic surfactants used worldwide. These products can reach water bodies through the discharge of untreated sewage or non-effective treatments. This study evaluates the ability of the microorganisms found in the Tiete river sediment to degrade this synthetic surfactant...

With spectacular growth in demand since opening the market to foreign competition, executives within the Macau casino industry have focused their attention on enhancing capacity and opening new casino properties. Meanwhile, the Singapore casino market, barely two years old, has already produced revenues comparable to the Las Vegas Strip. Despite stellar past successes, the long-term scenario fo...

In Brazil, the recognition that fisheries encompass both natural ecosystems and human well-being has increased, but initiatives are focused largely on highly-valued species, ignoring socially relevant resources such as Venus clams (Anomalocardia brasiliana). We investigate two initiatives involving comanagement of Venus clams in the past two decades: the Marine Extractive Reserve "Pirajubaé" an...

Organ Allocation In response to perceived inequities of the existing timebased system, and under mandate of the federal government, a new lung allocation system was introduced in the United States in 2005. This system allocates organs on the basis of medical urgency (risk for death without transplantation) and “net transplant benefit” (the extent to which survival is increased with, as opposed ...

Recent studies of Internet traffic have shown that flow size distributions often exhibit a high variability property in the sense that most of the flows are short and more than half of the total load is constituted by a small percentage of the largest flows. In the light of this observation, it is interesting to revisit scheduling policies that are known to favor small jobs in order to quantify...

A family of Large Area Synchronised (LAS) codes is studied, which exhibits a so-called Interference Free Window (IFW), where both the Inter Symbol Interference (ISI) and the Multiple User Interference (MAI) are suppressed, provided that the relative time offset of the codes is within the IFW. Hence, LAS codes have the potential of increasing the capacity of CDMA networks. However, a specific dr...

A relatively simple shake-flask system for determining CO2 evolution was developed to assess the ultimate biodegradability by soil and sewage micro-organisms of chemicals which enter the environment. Linear alkylbenzene sulfonates (LAS) were used as model compounds to evaluate the method and were found to undergo substantial biodegradation in this dilute system. At the 30 mg/liter test concentr...
