BACKGROUND: Herpes simplex keratitis is a sight threatening ocular infection. A rapid and specific diagnosis is essential for the institution of specific antiviral therapy and to avoid complications that can arise from misdiagnosis and inappropriate treatment. Though a variety of techniques are available, isolation of Herpes simplex virus 1 (HSV-1) in culture provides the most reliable and spec...

An existing commercial scale low temperature R-502 refrigeration plant has been extensively instrumented for evaluating R-502 long term replacements R-404A, R-407A and R-507. This installation is part of the refrigeration plant located at the Thermal Technology Centre. The R-502 retrofit test facility has an internally compounded two stage 40 HP reciprocating compressor equipped with desuperhea...

Specimens submitted for diagnosis of herpes simplex virus (HSV) infection were inoculated into shell vials and reacted with a commercial DNA probe kit (Pathogene; Enzo Biochem, Inc., New York, N.Y.) and an immunofluorescence assay at 16 h postinoculation. The results were compared with isolation of the virus in conventional tube cell cultures. Of 504 specimens, 105 (20.8%) were positive for HSV...

The use of natural convection, side-arm heat exchangers in solar domestic water heating systems is becoming a popular method of reducing system cost and electric demand. In this paper, we compare thermal performances of three natural convection heat exchangers mounted along the outside of the water storage tank and a commercial wraparound-tank heat exchanger to two forced-flow heat exchangers. ...

Abstract The development of novel regenerators for caloric cooling applications requires a detailed evaluation their thermo-hydraulic properties. Structures similar to shell-and-tube heat exchangers are one the most promising geometries elastocaloric technology since they exhibit high thermal performance and can be applied under compressive loading overcome limited fatigue life materials normal...
