INTRODUCTION A growing number of studies have shown consistent evidence of the harmful effects of air pollution on human health, as well as its effects on newborn weight. The objective of this study is to evaluate the effect of air pollution on birth weight, more specifically the insufficient birth weight (identified between 2,500 and 2,999 grams). METHODS This was a cross-sectional study bas...

OBJECTIVE We assessed the relationship between active duty status and daily insufficient sleep in a telephone survey. METHODS U.S. military service status (recent defined as past 12 months and past defined as >12 months ago) and daily insufficient sleep in the past 30 days were assessed among 566,861 adults aged 18 to 64 years and 271,202 adults aged ≥ 65 years in the 2009 to 2010 Behavioral ...

The objective of the consistent-amplitude approach to quantum theory has been to justify the mathematical formalism on the basis of three main assumptions: the first defines the subject matter, the second introduces amplitudes as the tools for quantitative reasoning, and the third is an interpretative rule that provides the link to the prediction of experimental outcomes. In this work we introd...

Afibrinogenemia or hypofibrinogenemia is a quantitative defect in fibrinogen. It is a rare disease with estimated frequency of 1 in 1,000,000 population. Routine preoperative screening tests of coagulation disorders are insufficient to detect subtle disorders of fibrinogen. Herein, we report a child who was supposed to undergo open cardiac surgery for a large atrial septal defect. Preoperative ...

In low ambient temperatures the engine will have poor output torque and power generation at the first cycles of its performance, long start time and huge noxious emissions because of insufficient temperature and quality of air-fuel mixture and failure of flame to burn the charge. It is noted that any attempt to increase the charge temperature leads to better combustion conditions. By applying t...

This paper employs a general non-linear analysis tool to analyse the nature of time series associated with the price (returns) of a particular company in Tehran Stock Exchange. It is shown that the behavior of the process associated with the price (returns) time-series of this company is weakly chaotic, and due to the non-random behavior of the process, short term prediction of stock price is p...

In physical experimentation, the resources available to discover new knowledge are typically extremely small in comparison to the size and dimensionality of the parameter spaces that can be searched. Additionally, due to the nature of physical experimentation, experimental errors will occur, particularly in biochemical experimentation where the reactants may undetectably denature, or reactant c...

By combining hidden types and hidden action, this paper shows that the existence of credit rationing need not imply that lending exceeds the full-information level. In this plausible class of models, the appropriate policy is not to subsidise or tax lending but to make alternatives to entrepreneurship more attractive. Doing so may actually increase the number of those borrowing to set up their ...
