The current study explored the motivations of online social network use among a sample of the general population in Taiwan (N=4,346). It investigated how seven different motivations to use Facebook predicted the intensity of Facebook use and content-generation behaviors on Facebook. Results showed that the motivation to use Facebook for posting and viewing status updates was the strongest predi...

cars are one of the most important symbols of modern technology which contain various social and cultural messages about concepts like gender, ethnicity, age, social class, etc. and are interpreted differently based on the needs and motivations of users. since the main aim of this research is having a deep look at use of cars among female drivers, we will first take a look at the conceptual rel...

The purpose of this study was to assess reasons students seek a career in dentistry, their perceptions of the dental school admissions process, and their expectations of the profession. Of 155 predental students participating in a dental school simulation course offered at a Nevada dental school, 152 participated in this study (68.4 percent [n=104] male, and 31.6 percent [n=48] female). When as...

While previous research has been limited, this appears to be a higher rate than occurs within the general population, said Gong-Soog Hong, co-author of the study and professor of consumer sciences at Ohio State University. This study found that 71 percent of older adults used some form of alternative medicine in 2000. A study done in 2002, found a lower rate-about 62 percent – among all adults....

BACKGROUND AND PURPOSE Cigarette smoking is a risk factor for the formation and rupture of intracranial aneurysms. Few studies have examined predictors of resumption of cigarette smoking after a first episode of subarachnoid hemorrhage (SAH). METHODS Of 620 SAH patients treated between July 1996 and November 2002, we prospectively evaluated continued cigarette use in 152 smokers alive at 3 mo...

Ticlopidine is a first-generation thienopyridine antiplatelet drug that prevents adenosine 59-diphosphate (ADP)-induced platelet aggregation. We identified the enzymes responsible for the two-step metabolic bioactivation of ticlopidine in human liver microsomes and plasma. Formation of 2-oxo-ticlopidine, an intermediate metabolite, was NADPH dependent and cytochrome P450 (CYP) 1A2, 2B6, 2C19, a...

Protein tyrosine phosphorylation is a key regulatory modification in metazoans, and the corresponding kinase enzymes have diversified dramatically. This diversification is correlated with a genome-wide reduction in protein tyrosine content, and it was recently suggested that this reduction was driven by selection to avoid promiscuous phosphorylation that might be deleterious. We tested three pr...

We studied 152 COPD patients with a daytime PaO2 greater than or equal to 60 mm Hg using formal polysomnography (EEG, airflow, respiratory muscle movement, ear oximeter) to detect the presence of nocturnal, nonapneic, oxyhemoglobin desaturation. Nine subjects were disqualified by the unexpected discovery of sleep apnea, as were another eight because they could not sleep in the laboratory settin...

viscosity (µ) and density (ρ) are important physical roperties for analysis of membrane processes performance and for designing a new membrane process. in addition, the energy requirement for fluid pumping is depend on these two physical properties magnitiude. in this study, firstly, the effects of different process factors such as transmembrane pressure (51, 101, 152, 203 and 253 kpa), tempera...
