The objective was to evaluate lymphoid organ size in chickens from a series of 13 recombinant congenic strains (RCS) and their highly inbred parental lines (6(3) and 7(2)). The parental line 6(3) was selected for resistance to tumors induced by Marek's disease virus and avian leukosis viruses, whereas line 7(2) was selected for susceptibility to these tumors. Each RCS on the average contains a ...

A full-size aircraft engine-duct mock-up experimental apparatus has been built to collect cavity radar cross section (RCS) data on aircraft engine inlets. The engine-duct structure is made up of a cylindrical duct with a single fan stage consisting of 30 generic straight fan blades. Experimental results indicate that the azimuthal RCS patterns from the engine-duct are quite complex. Numerical c...

PURPOSE The authors investigated photopic electroretinographic changes during degeneration in the Royal College of Surgeons (RCS) and transgenic P23H rhodopsin rat models, including the cellular origins of a large corneal-negative component that persists in the RCS rat. METHODS Photopic and scotopic electroretinograms (ERGs) were recorded from dystrophic RCS (RCS-p(+)/Lav) rats (4-18 weeks ol...

The return link performance of conventional civil DVB-RCS transmission technology limits its direct application to air-borne satellite video transmission system. This paper studies the novel emergent DVB-RCS return link technique based on introducing adaptive parallel processing to the conventional civil DVB-RCS return link. Simulation results demonstrate that the proposed return link transmiss...

Either passive calibration targets are expensive and complex to manufacture or their bistatic RCS levels are significantly lower than the monostatic RCS levels of targets such as spheres, dihedraland trihedral corner reflectors. In this paper the performance of an active calibration target with relative high bistatic RCS values is illustrated as a reference target for bistatic RCS measurements....

Previous studies have revealed that the reticulum cell sarcoma (RCS) of SJL/J (H-2s, IE-) mice express an "IE-like" stimulatory tumor-associated antigen, the expression of which is requisite for stimulating host T cells necessary for tumor growth. Herein, we present evidence that the predominant T cells raised in the syngeneic response to both spontaneous and transplantable RCS tumors are of th...

Strengthening research capacity in low- and middle-income countries is one of the most effective ways of advancing their health and development but the complexity and heterogeneity of health research capacity strengthening (RCS) initiatives means it is difficult to evaluate their effectiveness. Our study aimed to enhance understanding about these difficulties and to make recommendations about h...

The Comprehensive System for the Rorschach (RCS) is currently the subject of intense scientific criticism. The normative data for many RCS scores are seriously in error and tend to make normal individuals appear maladjusted. Reliability is inadequate for many RCS scores, and validity for the great majority of RCS scores has not been adequately demonstrated. In addition, a substantial number of ...
