Solubility (vapor pressure) , viscosity and density have been experimentally determined for thirty-five potential refrigeration working fluids. Properties for low refrigerant concentration mixtures (0, 10, 20 and 30 weight percent refrigerant) were determined over the temperature range 0 to IOO•C (32 to 212"F) or to the critical temperature of the refrigerant, and pressure range 0 to 3,500 kPa ...

Previous studies demonstrated higher systolic intracellular Ca(2+) concentration ([Ca(2+)](i)) amplitudes result in faster [Ca(2+)](i) decline rates, as does β-adrenergic (β-AR) stimulation. The purpose of this study is to determine the major factor responsible for the faster [Ca(2+)](i) decline rate with β-AR stimulation, the increased systolic Ca(2+) concentration levels, or phosphorylation o...

Two complementary standards are compared, both of which are concerned with the production of quality software. One, IEC 61508, is concerned with the safety of software intensive systems and the other, ISO/IEC TR 15504, takes a process view of software capability assessment. The standards are independent, though both standards build on ISO/IEC 12207. The paper proposes a correspondence between t...

Although a classic staged maturity framework with 5 levels was introduced by W. S. Humphrey back in 1988, its basic ideas remain essentially unchanged and they are still employed in CMMI and other maturity models. ISO/IEC 15504, formerly known as SPICE, has promoted a continuous model for process capability assessment. Not long ago SPICE community recognized the benefits of a staged representat...

Hydrogen bonds and halogen bonds operate in concert in the directed assembly of infinite 1-D chains in binary co-crystals of iodine iso-nicotinamide (2 : 2), 1 and tetrafluorodiiodobenzene iso-nicotinamide (1 : 2) 2.

Isoflurane (ISO) exhibits neuroprotective effects against inflammation and apoptosis. However, the role of ISO in motoneuronal apoptosis induced by activated microglia remains poorly studied. We investigated the protective effects of ISO on the apoptosis of ventral spinal cord 4.1 (VSC4.1) motoneurons induced by lipopolysaccharide (LPS)-activated BV-2 microglia. Results indicated that ISO inhib...

The international community, including the International Organization for Standardization (ISO), is currently seeking more granular systems of language identifiers than the widely used tags of ISO 639 parts 1 and 2. There is growing need for the more precise identification and annotation of language-based resources. This paper presents a key response to this need, in which the Linguasphere Regi...

The current investigation was proposed to assess the effectiveness of combination resveratrol and ascorbic acid against Isoproterenol (ISO)-induced myocardial infarction in rats. experimental model divided into six groups (n = 6 each group). Group I: control, 2: isoproterenol (ISO)-100 mg/kg b.wt, 3: ISO+Resveratrol (RES) (20 b.wt) treated, 4: ISO+ Ascorbic (AA) (80 5: ISO+RES b.wt)+AA treated ...

In 2000, there was a workshop [1] that should foster the definition of a standard transfer format for Petri nets as a satellite event of the annual ‘Petri Net Conference’ in Aarhus. As a result of this first workshop, after many other discussions and meetings, the Petri Net Markup Language (PNML) is about to be finally adopted as ISO/IEC 15909-2. Over the years, PNML has evolved and, unfortunat...
