due to the existence of different criticism criteria in different eras, the critics have applied different and sometimes opposing methods in literary criticism. the present article studies the popular methods of literary criticism and the evolution of one special method which has been called preference in some era and comparison in some other era.

Immigrants are not new to us in Britain. The archaeologist gives evidence of wave after wave of them in the pre-Christian eras. They usually solved their problems of different language, looks and religions by conquering limited areas of land and imposing their culture on the existing people. This rough-and-ready solution was confirmed by the Roman, Scandinavian, Saxon and Norman invasions. Thro...

Scanning thermal microscopy has been implemented in a cross-sectional geometry, and its application for quantitative, nanoscale analysis of thermal conductivity is demonstrated in studies of an ErAs/GaAs nanocomposite superlattice. Spurious measurement effects, attributable to local thermal transport through air, were observed near large step edges, but could be eliminated by thermocompression ...

We report the fabrication and characterization of segmented element power generator modules of 16 x 16 thermoelectric elements consisting of 0.8 mm thick Bi2Te3 and 50 μm thick ErAs:(InGaAs)1-x(InAlAs)x with 0.6% ErAs by volume. Erbium Arsenide metallic nanoparticles are incorporated to create scattering centers for middle and long wavelength phonons, and to form local potential barriers for el...

the present article studies the history of the related lexicon and the influence way of these lexicons to the arabic language in different eras before and after islam to the contemporary era. the arabian people were from different tribes who have connected to all neighbor nations because of the economic, political, religious and cultural reasons and factors. at that very time the arabian people...

AIM  The aim of this study was to systematically review the literature on the influence of enhanced recovery after surgery (ERAS) protocols and health related quality of life (HQoL) and patient satisfaction. METHOD A systematic review of the literature from January 1990 to February 2009 was undertaken. Studies were included if they compared HQoL and/or patient satisfaction after ERAS and conv...

Scanning capacitance microscopy is used to characterize the electronic properties of ErAs nanoparticles embedded in GaAs pn junctions grown by molecular beam epitaxy. Voltage-dependent capacitance images reveal localized variations in subsurface electronic structure near buried ErAs nanoparticles at lateral length scales of 20-30 nm. Numerical modeling indicates that these variations arise from...

We describe GaAs-based tunnel junctions that are compatible with photonic devices, including long-wavelength vertical-cavity surface-emitting lasers and multi-junction solar cells. Tunneling was enhanced with semimetallic ErAs nanoparticles, particularly when grown at reduced substrate temperatures. Additionally, we present the first direct measurement of the quality of III-V layers grown above...
