We report 60 and 90 µm observations of 7 millisecond pulsars with ISO. The pulsar PSR B1257+12 is orbited by three planets, and other millisecond pulsars may be orbited by dust disks that represent planets that failed to form or their residue. We do not detect any infrared emission from the 7 pulsars in our sample, and typical upper limits are 100 mJy. Using a simple model, we constrain the typ...

This study was carried out among urban, rural and refugee camp populations in three localities (Rimal, Jabalia Village, Jabalia Refugee Camp), in Gaza Governorates – Palestine. School children between 6 and 11 years old were examined. The prevalence of intestinal parasites among 309 school children was higher in the rural area (53.3%) and the Refugee Camp (48.0%) than in urban areas (33.0%). Ma...

OBJECTIVE To describe the behavior of mortality in Mexico through four indicators from 1990 to 2012. MATERIAL AND METHODS The official mortality and population records of Mexico were used. RESULTS An advance was achieved for children under five years of age, with a decrease in mortality, although there was an increase in the years of potential life lost (YPLL) from 2008 for this age group. ...

Pulsar spindown forms a reliable yet enigmatic prototype for the energy loss processes in many astrophysical objects including accretion disks and back holes. In this paper we review the physics of pulsar magnetospheres, concentrating on recent developmen ts in force-free modeling of the magnetospheric structure. In particular, we discuss a new method for solving the equations of time-dependent...

In markets as diverse as that for specialized industrial equipment or that for retail financial services, sellers or intermediaries may earn profits both from the sale of products and from the provision of pre-sale consultation services. We study how a seller optimally chooses the costly quality of pre-sale information, next to the price of information and the product price, and obtain clear-cu...

▲ Tina Meier, the mother of Megan Meier, displays photographs of her daughter, who committed suicide at the age of thirteen after reacting to fake MySpace postings by the mother of one of her former friends. Studying sociology provides us with new insights on problems such as suicide by making us aware that much more goes on in social life than we initially observe. His name was Josh Evans. He ...

redescribing reality in scientific terms, as if the findings of science are a disclosure of Ltitlehampton inherent properties of the ultimate real (The Quest for Certainty, Later Works 19811991). A wellbeing-centered binay of development implies a more aggressive focus on the states traditional role in delivering collective goods and Order binary option Floydada, like health, education, clean a...

The aim of this paper is to analyse what strategies may be the most suitable ones when dealing with problems in the translation of a text on human trafficking. The focus of the study is how to translate terminology related to human trafficking, but also on how to deal with references to culture-specific phenomena. In order to find possible solutions for translation problems in the text, differe...

This paper studies the strategic interaction between a monopolistic seller of an information product and a set of potential buyers that compete in a downstream market. Our analysis illustrates that the nature and intensity of competition among the information provider’s customers play first-order roles in determining her optimal strategy. We show that when the customers view their actions as st...
