We investigate the secular resonances for massless small bodies and Earth-like planets in several planetary systems. We further compare the results with those of Solar System. For example, in the GJ 876 planetary system, we show that the secular resonances ν1 and ν2 (respectively, resulting from the inner and outer giant planets) can excite the eccentricities of the Earth-like planets with orbi...

Although racial/ethnic differences have been found in the use of mental health services for depression in the general population, research among Veterans has produced mixed results. This study examined racial/ethnic differences in the use of mental health services among 148 Operation Enduring/Iraqi Freedom (OEF/OIF) Veterans with high levels of depression and posttraumatic stress disorder (PTSD...

A system of equations is derived for the secular motion of a hierarchic triple stellar system. Mean anomalies of the inner binary system and of the outer star orbit are eliminated up to order 9 in the ratio of their Delaunay momenta. Thanks to the use of vectorial elements (angular momenta and Laplace vectors) the equations are non-singular, compact, and independent on the choice of the referen...

each historical period contain a special conception about god, man and the world by which it is distinguished from the others. at the beginning of modernity, western man has accepted a new conception toward these problems. relation between ethics and religion within modernity, depend on such conception. while in the prior periods, especially in the middle age, ethics had been known to be depend...

Time-consuming and costly religious rituals pose a puzzle for economists committed to rational choice theories of human behavior. We propose that religious rituals promote in-group trust and cooperation that help to overcome collective-action problems. To test this hypothesis we design field experiments to measure the in-group cooperative behavior of members of religious and secular Israeli kib...

The secular perturbations exerted by an inclined satellite orbiting in a gap in a broad planetary ring tends to excite the inclinations of the nearby ring particles, and the ring’s self–gravity can allow that disturbance to propagate away in the form of a spiral bending wave. The amplitude of this spiral bending wave is determined, as well as the wavelength, which shrinks as the waves propagate...

BACKGROUND U.S. epidemiologic surveys have consistently found higher lifetime prevalence of alcohol dependence among younger subjects than among older groups. Because lifetime prevalence is cumulative, such patterns are suggestive of strong secular trends; i.e., more-recently born subjects have developed more disease in a shorter period of time than their elders. However, it remains unclear whe...

Statural growth is dependent on hereditary and environmental factors, i.e disease, nutrition. The improvement of socioeconomic conditions that took place during the 20th century resulted in a secular trend towards greater height and earlier sexual maturation. Greek society has changed dramatically from a mainly agricultural society at the beginning of the 20th century to a mainly urban one in t...

BACKGROUND/OBJECTIVES Although secular trends have been well documented in the craniofacial region, there is no evidence to suggest that these temporal changes exist in samples used for orthodontic research. The aim of this study is to determine the effect of secular trends on craniofacial growth in a series of longitudinal birth cohorts that are frequently used in orthodontic research. MATER...

This article aims to analyze in more detail the role of evangelism throughout US history, especially during revolution. In this article, which aim provide an overview intersection religion and philanthropy United States, case study design, one qualitative research designs, was used. The data were analyzed using descriptive analysis technique. obtained technique are summarized interpreted accord...
