The study of the approximability properties of NP-hard optimization problems has recently made great advances mainly due to the results obtained in the eld of proof checking. The last important breakthrough shows the APX-completeness of several important optimization problems is proved and thus reconciles`two distinct views of approximation classes: syntactic and computational'. In this paper w...

INTRODUCTION We report a case of neurogenic pulmonary oedema (NPO) following massive left cerebral infarct, which was initially misdiagnosed as acute myocardial infarction (AMI). CLINICAL PICTURE This 52-year-old man presented with acute loss of consciousness with normal brain computed tomography (CT). He was treated as non-ST-elevation AMI complicated with pulmonary oedema based on findings ...

background: we investigated the effects of cigarette smoking in non-per os (npo) period on volume and ph of gastric contents in smoker male patients. methods: in a prospective cohort study, 86 male smoker patients undergoing elective non-abdominal surgery under general anesthesia, were surveyed. they were npo for at least 8-12 hrs. prior to surgery without direction to smoking. then they were d...

Nonprofit organization (NPO) marketers are now increasingly turning online to recognize donors, with little understanding as how donor appreciation influences behavior. A scenario-based research design using an survey was administered a random sample of voluntary blood donors ( n = 356). The findings contribute identity theory by demonstrating that recognition (digital badge shared Facebook) ca...

The Central Pacific (CP) and Eastern (EP) types of El Niño-Southern Oscillation events are distinctly different in terms their forming locations mechanisms. Using an updated physical-base statistical forecast model, the CP indices has overall higher skills than that EP due to persistent skill. At lead time beyond 6-month, predictability can be greatly enhanced by including extratropical precurs...

Abstract Owing to the significant influence of El Niño-Southern Oscillation (ENSO) on global climate, how ENSO events are initiated is an intriguing issue. The North Pacific (NPO), a primary atmospheric variability over midlatitude, well-known trigger for events, but physical linkage not yet fully understood. Based observational analyses, in Part I, we proposed new mechanism that NPO-related wa...

Sister-chromatid exchange (SCE) and chromosome aberrations (CA) in bone marrow cells were analyzed after in vivo exposure in mice to 4 aliphatic epoxides, namely 1-naphthyl glycidyl ether (NGE), 1-naphthyl propylene oxide (NPO), 4-nitrophenyl glycidyl ether (NPGE) and trichloropropylene oxide (TCPO). These compounds were selected as being among the most mutagenic aliphatic epoxides in our previ...
