Beautiful people earn more. Surprisingly, this premium is often larger for men than for women, and is independent of customer contact, e.g., even in software engineering. Overlooked is the possibility that beauty can influence college admissions. We investigate this academic contributor to the labor market beauty premium by sampling 1,800 social media profiles of students from universities rank...

This study examines clean water management in Bandung, West Java, Dutch East Indies (Indonesia), from the late 19th Century to early 20th Century. focuses on how human community has modified physical unit, including technology, skills, and social environmental priorities. Historical methods were applied investigate topic, heuristics, verification, interpretation, historiography. Most of data th...

Abstract Isotope hydrological studies carried out since 1987 in Haiti have proven to be effective improving conceptual models of the principal aquifers this Caribbean island nation. However, many these been limited and are mostly unpublished. It is, therefore, important share available datasets with scientists water managers support further guide decision-making. Eleven were compiled a unique d...

A new, systematic approach to the synthesis of Cartesian sti®ness by springs is presented using screw (spatial vector) algebra. The space of solutions is fully characterized for all sti®nesses realizable by springs. The main result shows that a rank r sti®ness can always be synthesized by r springs. Further, it can also be synthesized by an arbitrarily large number of springs greater than r: Sy...

Abstract This study presents the first hydrogeochemical model of hydrothermal systems Turrialba and Irazú volcanoes in central Costa Rica, manifested as thermal springs, summit crater lakes, fumarolic degassing at both volcanoes. Our period observations (2007–2012) coincides with pre- early syn-phreatic eruption stages volcano that resumed volcanic unrest since 2004, after almost 140 years quie...

introduction:  all of  the  people worldwide  are exposed  to  low levels  of  radiation. cancer induction  and  genetic disorders are among the hazards of low level exposure. in some cases, radiation close to hot springs is  higher than normal areas due to a high concentration and the decay products of ra-226. given the use of hot  springs by the general public  because  of their therapeutic p...
