Through high coverage whole-genome sequencing and imputation of the identified variants into a large fraction of the Icelandic population, we found four independent signals in the low density lipoprotein receptor gene (LDLR) that associate with levels of non-high density lipoprotein cholesterol (non-HDL-C) and coronary artery disease (CAD). Two signals are novel with respect to association with...
the application of a comprehensive model of communicative language ability (cla) to language teaching and testing has always been an imperative in l2 education since hymess proposal of communicative competence in the 1970s. recent l2 research has clearly underscored the importance of sufficient pragmatics representation as an essential component of cla in pedagogical and testing practices in l2...
abstract the present study was conducted to examine the effect of proficiency on students interaction while carrying out the grammar-based task(s) in collaboration. in particular, the study examines whether the level of proficiency affects the learners’ focus of attention to grammatical and lexical features. the study takes a further step and examines whether there is any difference in the use...
an essential characteristic for high performance inherently hydrophobic membranes such as microporous high density polyethylene (hdpe) membranes is to have a hydrophilic surface. in this project, wet chemical functionalization as a facile and effective method was developed to give a hydrophilic property to hdpe membranes using polar functional groups. kclo3, k2cr2o7 and kmno4 were selected as o...
A procedure is presented and evaluated for separation of plasma high density lipoprotein from either capillary or venous whole blood. The lipoprotein is separated by adding 50 microliter of sample to 250 microliter of 0.15 M NaCl solution containing 99.9 g/l polyethyleneglycol 6000, 0.0374 g/l dextran sulfate (Mr 15,000) and 2.6 mM Mg2+. After gentle mixing for a few minutes and standing 10 min...
Mammalian somatic cells do not catabolize cholesterol and need to export it for its homeostasis at the levels of cells and whole bodies. This reaction may reduce intracellularly accumulated cholesterol in excess and would contribute to prevention or regression of the initial stage of atherosclerosis. High-density lipoprotein (HDL) is thought to play a main role in this reaction, and 2 independe...
As logic systems get larger and more complex, their supply current requirements continue to rise. Systems requiring 100A are fairly common. A high current power supply to meet such requirements usually requires paralleling several power regulators to alleviate the thermal stress on the individual power components. A power supply designer is left with the choice of how to drive these paralleled ...
