Specimens from 95 patients attending a venereal diseases clinic were examined for gonococci by three methods--a conventional culture technique using modified Thayer-Martin medium, microscopy of a Gram-stained direct smear, and the Microcult system. For 56% of the specimens the results by all three methods agreed. Assuming the results obtained by culture on Thayer-Martin medium to be correct, th...

Fungemia is associated with high morbidity and mortality rates. Various techniques have been introduced to diagnose fungemia such as conventional broth culture medium, by blind or macroscopic subculture, vented and aerated biphasic culture medium, lysis Þ ltration agitated culture medium, radiometric and nonradiometric methods, lysis centrifugation method, etc..[1] Of these, lysis-centrifugatio...

This paper presents a theory of the radar cross section (RCS) of objects in multiple scattering random media. The general formulation includes the fourthorder moments including the correlation between the forward and the backward waves. The fourth moments are reduced to the second-order moments by using the circular complex Gaussian assumption. The stochastic Green’s functions are expressed in ...

Theoretical rates of annual genetic responses to selection in beef cattle were compared for conventional and multiple ovulation and embryo transfer (MOET) breeding schemes. Several combinations of replacement policy, mating ratio and type of selection were considered for both schemes with low, medium and high heritabilities. For MOET, four rates of embryo transfers per donor were used to repres...

Here, we present a novel method for culturing kidneys in low volumes of medium that offers more organotypic development compared to conventional methods. Organ culture is a powerful technique for studying renal development. It recapitulates many aspects of early development very well, but the established techniques have some disadvantages: in particular, they require relatively large volumes (1...

Intravenous angiography is a a safe, rapid, simple examination, which, with sonography, is complementary in selecting patients for conventional angiography. This examination is not designed to replace conventional angiography, but, rather, to study high-risk stroke patients, patients with asymptomatic cervical bruit, or postoperative patients. Improvements in contrast media, film subtraction, t...

This study set out to examine the cystoseira gibraltarica extract (CG) as an environmentally sustainable corrosion inhibitor for carbon steel in 1.0 M HCl medium. The corrosion inhibiting effect has been studied by conventional methods such as gravimetric (weight loss) and electrochemical (EIS and PDP) methods. All the methods used in this study confirm that cystoseira gibraltarica extract has ...

Investigations were carried out to evaluate the performance of direct injection diesel engine with medium grade low heat rejection (LHR) combustion chamber and 3 mm air gap insulated piston, 3 mm air gap insulated liner, and ceramic coated cylinder head [ceramic coating with the thickness of 500 µ was made on the inside portion of the cylinder head].The engine had different operating conditions...
