Effect of Locust Bean Pod Ash and Eggshell Ash on the Mortar Compressive and Flexural Strengths of Cement Blends [PDF]

open access: yes, 2020
An increase in the generation of biogenic wastes such as locust bean pods and eggshells coupled with the need to drive sustainability in the cement industry has led the use of these wastes as cement replacement materials.

Carrier scattering approach to the origins of dark current in mid- and far-infrared (terahertz) quantum-well intersubband photodetectors (QWIPs) [PDF]

open access: yes, 2001
A carrier scattering approach is taken in an analysis of the affect on the dark current of extending the operating wavelength of conventional bound to continuum quantum-well intersubband photodetectors. It is found that both the sequential tunneling and

BIRICODAR (VX-710; Incel™): an effective chemosensitizer in neuroblastoma [PDF]

open access: yesBritish Journal of Cancer, 1999
Clinical studies have suggested that both MDR1 and MRP may play a significant role in the chemosensitivity and outcome of neuroblastoma. To clarify the nature of multidrug resistance (MDR) in this tumour a series of six neuroblastoma cell lines have been characterized with regard to P-glycoprotein, MRP and LRP expression using immunocytochemistry and ...

Physical properties of the jet in 0836+710 revealed by its transversal structure [PDF]

open access: yes, 2007
Studying the internal structure of extragalactic jets is crucial for understanding their physics. The Japanese-led space VLBI project VSOP has presented an opportunity for such studies, by reaching baseline lengths of up to 36,000 km and resolving ...

Gamma-loud quasars: a view with BeppoSAX [PDF]

open access: yes, 2000
We present $Beppo$SAX observations of the $\gamma $-ray emitting quasars 0836+710, 1510-089 and 2230+114. All the objects have been detected in the PDS up to 100 keV and have extremely flat power-law spectra above 2 keV ($\alpha _x$=0.3--0.5).

Interaction as enquiry: learning with layered dynamic media [PDF]

open access: yes, 2003
The interactivity afforded to the learner by the computer based media is often fairly restricted. This may be by design choice but is often brought about by resource constraints.

The Good, The Bad, and the Ugly: Job Quality in the United States over the Three Most Recent Business Cycles [PDF]

open access: yes, 2007
This report finds that the US economy has created fewer good jobs in the 2000s than was the case over comparable periods in the 1980s and 1990s. The report analyzed annual data from the March Current Population Survey for the years 1979 through 2006 and ...
