the purpose of the research is to examine if integrating cooperative learning into vocabulary learning helps to increase word recognition of students in an elementary school in iran. it tries to investigate whether cooperative learning approach enables students to improve their language learning. this research used stad (students team achievement division) as a cooperative model in this study. ...
Test Re-Test Repeatability of the Strain Index. (May 2003) John-Paul Stephens, B.S., Texas A&M University Chair of Advisory Committee: Dr. J. Steven Moore The Strain Index (SI) has repeatedly shown high levels of validity for differentiating between safe and hazardous tasks for the distal upper extremity (DUE). One limitation of the SI is the lack of reliability data. This study was designed to...
A diffuse reflectance infrared Fourier-transform (DRIFT) study has been conducted at 373 K and 1 bar on an industrial Cr/Ti/SiO2 Phillips-type catalyst modified with, and without, triethylaluminium (TEAl) as co-catalyst. The reaction rate of the polymerization of ethylene, as monitored by the increase in the methylene stretching band of the growing polyethylene (PE), has been investigated as a ...
Resumen-En este trabajo presentamos una aproximación para el desarrollo de Bases de Datos (BD) Objeto-Relacionales (OR) en el marco de MIDAS, una metodología dirigida por modelos para el desarrollo de Sistemas de Información Web. En nuestra propuesta, el Modelo Independiente de la Plataforma (PIM, Platform Independent Model) será el modelo conceptual de datos y a partir de éste obtendremos el M...
تأٌثیر آموزش تغذیه و بهداشت با مدل ادراکی به مادران بر رشد دانشآموزان راهنمایی دخترانه شیراز (1384)
Back ground and Aim: According to the UNICEF’s Conceptual Model the behavior of those who somehow play a role in taking care of children significantly influences children’s growth as a feedback. Anthropometrical indices such as weight and height for age Z (HAZ and WAZ) are extensively utilized to determine malnutrition and growth rate. Materials and Methods: In a quasi experimental study...
Although Ziegler–Natta (ZN) catalysts play a major role in the polyolefin market, true understanding of their properties at molecular level is still missing. In particular, there lack knowledge on electronic Ti sites. Theoretical calculations predict that electron density sites precatalysts correlates with activation energy for olefin insertion Ti-alkyl bond generated these after by Al-alkyls. ...
The compensatory growth, proximate composition and amino acid contents changes of young yellow catfish (Pelteobagrus fulvidraco R.) (1.63-1.69 g) had been investigated using a 45-day cyclic feed deprivation and re-feeding experiment. The control group (S0) was fed daily with live tubificid worms (Limnodrilus hoffmeisteri), while the S1/4, S1/2, and S1/1 groups cyclically experienced one-day of ...
Animals respond to adverse environments by slowing down or arresting growth and development. Upon returning to normal conditions, they often show compensatory acceleration in growth and developmental rate. This phenomenon, known as `catch-up' growth, is widely documented in the animal kingdom. The underlying molecular mechanisms, however, are poorly understood. Using the zebrafish embryo as an ...
