We have observed NGC 3603, the most massive visible H II region known in the Galaxy, with ANTU(VLT1)/ISAAC in the near-infrared (NIR) Js, H , and Ks-bands. Our observations are the most sensitive observations made to date of this dense starburst region, allowing us to investigate with unprecedented quality its low-mass stellar population. Our mass limit to stars detected in all three bands is 0...

In a short interval toward the end of 1694, Isaac Newton developed two mathematical models for the theory of the astronomical refraction and calculated two refraction tables, but did not publish his theory. Much effort has been expended, starting with Biot in 1836, in the attempt to identify the methods and equations that Newton used. In contrast to previous work, a closed form solution is iden...

International comparative studies, investigating whether disease incidence or prevalence rates differ between populations and, if so, which factors explain the observed differences, have made important contributions to the understanding of disease aetiology in many areas. In Phase I of the International Study of Asthma and Allergies in Childhood (ISAAC), the prevalence rates of symptoms of asth...

In 1998, an epidemiological study on asthma and allergic diseases using ISAAC questionnaire in Laos was first conducted in the recommended schools located in Vientiane capital showing that the prevalence of rhinoconjunctivitis and atopic eczema were 23.7% and 7.1% among children aged 13-14 year-old, respectively. This study aimed to reassess the prevalence of rhinoconjunctivitis and atopic ecze...

The prevalence of asthma remains difficult to determine with precision with no absolute or gold standard for diagnosis. International Study of Asthma and Allergies in Childhood (ISAAC) developed video questionnaire for epidemiological studies with less reliance on understanding written asthma questionnaire. The aim of this research was to determine the agreement between the ISAAC written and vi...

The free riding hypothesis has been the subject of laboratory experiments for more than a decade. While the extent of free riding has often varied across experiments, three observations are consistently replicated. First, there is no significant evidence of free riding in single-shot games. Marwell and Ames (1981) for instance, found that subjects generally provide the public good at levels hal...
