Do Class and School Size Matter? A Crucial Issue to School Improvement

AN EXPERIMENTAL INVESTIGATION ON IMPROVING THE MEDIUM AND LATE-AGE COMPRESSIVE STRENGTHS OF CLASS G OIL WELL CEMENT

In this study, the effects of particle size distribution improvement and dense packing techniques on the 28- and 90-day compressive strengths of class G oil well cement have been investigated. It was observed that limited improvements in the particle size distribution of cement (regarding industrial possibilities) cannot result in a significant increase in 28- and 90-day compressive strengths. ...

Closing the achievement gap between high-poverty schools and low-poverty schools

We examine the achievement gap between low-income minority students in inner city (high-poverty) schools and their white high-income counterparts who attend suburban (lowpoverty) schools. Our data include the 4 and 5 grade math and reading scores for over 15,000 students in a large urban school district. We use a multilevel model to show that school resources do matter. We find that high qualit...

Investigation of the Improvement of Energy Generation by Pressure Retarded Osmosis

Knowing the overall solute flux and the partial fluxes expressed by every single transport layer, the membrane internal interface concentrations can separately be expressed. Both the overall transport coefcient and the driving force strongly depend, among others, on the value of the structural parameter and the water permeability. Study of the interface concentrations as ...
