We have observed the black hole candidate and Galactic superluminal source GRS 1915+105 with ISO LWS and SWS in March 1996 and March 1997 when the source was at fairly low X-ray and radio flux levels. If the source is associated with a dense molecular cloud, then corresponding far-IR continuum and line fluxes should be easily detectable and the data should constrain models for accretion from IS...

This study investigated the effects of delay of reinforcement on the classroom academic behaviors (rate of increase and accuracy of mathematical problem coapletion) by elementary students. A total of 11 fourth graders with a history of low achievement in arithmetic were divided into two groups and given timed arithmetic tests daily. Three reinforcement conditions were used (immediate, 1-day del...

Each member of the Larch family of formal specification languages has a component derived from a programming language and another component common to all programming languages. We call the former interface languages, and the latter the Larch Shared Language. This paper presents version 1.1 of the Larch Shared Language. It has two major sections. The first part starts with a brief introduction t...

pathogenicity of beauveria bassiana strain debi001, lecanicillium muscarium strain daom 198499 and their combination was investigated on 2nd nymphs and adults of b. tabaci in lab condition (in a germinator, 23±1ºc, 95±5% and 16:8 l:d). five concentrations of each fungi were sprayed on undersides of young eggplant leaves that involved 2nd nymphs. experiments were carried out on adults with the s...

In this paper, on the basis of first-principles, CASTEP module Materials Studio is used to calculate band structures and optical properties CuFeSe2 CuFeS2 under PBE pseudopotential generalized gradient approximation (GGA). The calculated results show that both are direct bandgap semiconductors with forbidden widths 0.64 eV 1.06 eV, respectively. visible light range, highest absorption coefficie...
