A novel double distilled water plan t has been designed and fabri cated w ith the main obj ecti ves to overcome the drawbacks of ex isting conventional plants and to save energy. T he deta il ed schematic drawing of the plant is given; its operating proced ure is al so discussed. Its work ing is based on a non-convention al method of vapori zing water. A ll the aspects of the experimental obser...

The field of disaster management in South Africa has developed dramatically over the past seven years. The paradigm shift from civil protection to disaster risk management brought with it the realisation that the nianagemeni of disaster risk is paramount to reducing successfully the vulnerability of these communities mo.st at risk. The resilience and coping mechanisms of communities affected by...

Of interest here is the influence of imperfections on the stability ofelastic systems. discrete or continuous. with nearly simultaneous modes. The majority of such structures show an extreme sensitivity of their first instability load to the shape of these small amplitude but unavoidable imperfections. The determination of the worst such possible shape is thus a very important issue from the de...

oncogenic RNA viruses. It has also been reported (24) that single-stranded polyribonucleotides at very low concentrations inhibit DNA polymerase of Rauscher leukemia virus. In this report, we present data that show a way in which RNA indirectly affects DNA synthesis. These data show that RNA markedly inhibits ribonucleotide reducÃ-asefrom Ehrlich ascites tumor cells, at concentrations which cou...

National Institute of Standards and Technology, Gaithersburg, MD 20899-0001 The Low Background Infrared Calibration Facility (LBIR) at the National Institute of Standards and Technology has been in operation for calibration measurements of ihe radiant power emitted fn>rn infrared radiation (IR) sources, such as cryogenic blaclcbodies, for more than 2 years. The IR sources arc sent to NIST by Cu...

Integration profiles collaboratively developed by CDISC and IHE for integrating data from Electronic Health Records (EHRs) with clinical research and pharmacovigilance are limited to resolving lexical/syntactic data integration issues and do not address semantic barriers. This paper describes the collaboration between two European projects - EHR4CR and SALUS - in implementing ISO/IEC 11179-base...

In this paper, the parho-physiological dynamics of HlV-/ induced AIDS is analyzed using Q system oj deterministic ordinary differential equations. The mathematical model exhibits explicitly the dynamics of the HlV-J virions during latency phase in the absence of anti-viral therapy. The model presented in this paper is a generalization of previous models of HlV-J dynamics and incorporales Ihe in...

Ci.—Aspen stands and riparian areiis are important to breeding birds in ihe southwestern U.S. because they provide tesources such as food atid shelter. We investigated how this importance varies throughoul the year for bolh resident and migratory birds. We sampled hitds in 96 sites, half in small isolated aspen stands and half in the ponderosa pine forest in northern Ariirona thiring tlie sumiu...

E xercise is generally recommended for individuals with type 1 diabetes because it is associated with numerous physiological (1,2) and psychological (3,4) benefits. However, participation in exercise can also increase the risk of experiencing severe hypoglycemia, during both exercise (5) and recovery (6). Unfortunately, there are no evidence-based guidelines for safe participation in intermitte...
