In December 2015, at the request of the Washington State Division of Behavioral Health and Recovery (DBHR), the University of Washington Alcohol & Drug Abuse Institute (ADAI) put forth an inventory of evidence-based programs and practices (EBPs) for treating substance use in adolescents and (12-17 years old) and young adults (18-20 years old). The analysis focused exclusively on substance use-r...
Radiative and mechanical feedback of massive stars regulates star formation galaxy evolution. Positive triggers the creation new by collecting dense shells gas, while negative disrupts shredding molecular clouds. Although key to understanding formation, their relative importance is unknown. Here, we report velocity-resolved observations from SOFIA (Stratospheric Observatory for Infrared Astrono...
all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
for several years, researchers in familiarity of efl teachers with post-method and its role in second and foreign language learners’ productions have pointed out that the opportunity to plan for a task generally develops language learners’ development (ellis, 2005). it is important to mention that the critical varies in language teaching was shown is the disappearances of the concept of method ...
We present colour-colour and colour-magnitude diagrams for RCW 57 (NGC 3576) based on L-band data at 3.5 μm taken with SPIREX (South Pole Infrared Explorer), and 2MASS JHKs data at 1.25-2.2 μm. A total of 251 sources were detected. More than 50% of the 209 sources included in the diagrams have an infrared excess. The IR-excess is interpreted as coming from circumstellar disks and hence gives th...
Progenitor Constraint with Circumstellar Material for the Magnetar-hosting Supernova Remnant RCW 103
Abstract Stellar winds blown out from massive stars (≳10 M ⊙ ) contain precious information on the progenitor itself, and in this context most important elements are carbon (C), nitrogen (N), oxygen (O), which produced by CNO cycle H-burning layer. Although their X-ray fluorescence lines expected to be detected swept-up shock-heated circumstellar materials supernova remnants, those of C N have ...
in the area of vocabulary teaching and learning although much research has been done, only some of it has led to effective techniques of vocabulary teaching and many language learners still have problem learning vocabulary. the urge behind this study was to investigate three methods of teaching words. the first one was teaching words in context based on a traditional method of teaching that is,...
—We studied wintering grassland bird communities in De Soto National Forest in southern Mississippi, USA to assess differences in bird communities and vegetation structure among different stand types. We also examined which vegetation structure and plant species predicted occurrence of Bachman’s Sparrow (Peucaea aestivalis), Henslow’s Sparrow (Ammodramus henslowii), and Sedge Wren (Cistothorus ...
