This study presents a typology for Online Learning Communities (OLC). People have always been members of different learning groups. OLC is about people who share a common interest and learn in a collaborative mode using information and communication technology (ICT). People communicate globally and exchange information with expectations to find others interested in the same subject. The aim of ...

The electrical membrane potential (delta psi) of chicken embryo fibroblasts in tissue culture was determined to be -30.5 +/- 2.9 mV as measured by distribution of the lipophilic [3H]tetraphenylphosphonium cation (Ph4P+). Stimulation of the electrogenic activity of the Na+,K+-ATPase by the ionophore monensin induces a hyperpolarization of approximately 47 mV and a new delta psi of -77.3 +/- 5.7 ...

An endogenous ouabainlike compound (OLC) has been purified from human plasma, and mass spectrometry has shown it to be indistinguishable from plant-derived ouabain. This human OLC was tested for its effects on evoked tension in guinea pig left atria and aortic rings. The tissues were incubated at 37 degrees C in bicarbonate-buffered physiological salt solution gassed with 95% O2-5% CO2. In atri...

in recent years many researchers have been focused on interaction of small molecules with dna. dna is generally the primary intracellular of anticancer drugs, so the interaction between small molecules and dna can cause dna damage in cancer cells, blocking the division of cancer cells and resulting in cell death. the flavonoids are a large group of polyphenolic natural products that are widely ...

OBJECTIVE To evaluate data from an online chlamydia testing program (OLC) developed to increase young people's access to testing for chlamydia, the most commonly notified disease in Australia and Western Australia, with a high proportion of notifications among young people (< 30 years). DESIGN AND SETTING The OLC was launched in February 2010, and our study covers the period February 2010 to ...

testing plays a vital role in any language teaching program. it allows teachers and stakeholders, including program administrators, parents, admissions officers and prospective employers to be assured that the learners are progressing according to an accepted standard (douglas, 2010). the problems currently facing language testers have both practical and theoretical implications but the first i...

like any other learning activity, translation is a problem solving activity which involves executing parallel cognitive processes. the ability to think about these higher processes, plan, organize, monitor and evaluate the most influential executive cognitive processes is what flavell (1975) called “metacognition” which encompasses raising awareness of mental processes as well as using effectiv...

BACKGROUND Ventilation with low tidal volume (VT) is well recognized as a protective approach to patients with acute respiratory distress syndrome (ARDS), but the optimal level of positive end-expiratory pressure (PEEP) remains uncertain. This study aims to evaluate two protective ventilatory strategies sequentially applied in patients with early ARDS. METHODS In this prospective cohort study...
