Abstract In this study, we conducted peer instruction (PI) activities to promote student participation in the learning process and test hypothesis that PI improves achievement. Two ninth-grade classes were randomly assigned as treatment control groups. Pre-test post-test data obtained for measuring mathematics achievement trigonometry. Data analyzed using analysis of covariance procedures with ...

The goal of this study was to determine the baroreflex influence on systolic arterial pressure (SAP) and pulse interval (PI) variability in conscious mice. SAP and PI were measured in C57Bl/6J mice subjected to sinoaortic deafferentation (SAD, n = 21) or sham surgery (n = 20). Average SAP and PI did not differ in SAD or control mice. In contrast, SAP variance was enhanced (21 +/- 4 vs. 9.5 +/- ...

In this paper some upper and lower bounds for the greatest eigenvalues of the PI and vertex PI matrices of a graph G are obtained. Those graphs for which these bounds are best possible are characterized.

Abstract Background The purpose of the study was to investigate whether pelvic incidence (PI) will affect occurrence PJK in Lenke 5 AIS patients after correction surgery and try explore a better surgical scheme based on PI. Methods 5C that underwent with minimum 2-year follow-up were identified. Demographic radiographic data collected preoperatively, postoperatively, at final follow-up. compari...

PURPOSE The aim of this study was to evaluate the effects of pharmacologic mydriasis and Peripheral Iridotomy (PI) on ocular biometry and anterior chamber parameters in primary angle closure suspects. METHODS In this prospective interventional case series, 21 primary angle closure suspects were enrolled. Intraocular pressure, refraction, ocular biometry (Lenstar, LS900), and anterior chamber ...

Our hypothesis is that impairment of peroxisome proliferator-activated receptor-gamma (PPARgamma) initiates renal dysfunction by increasing renal glomerular matrix metalloproteinase-2 (MMP-2) activity because of increased renal homocysteine (Hcy) and decreased nitric oxide (NO) levels. C57BL/6J mice were made diabetic (D) by being fed a high-fat-calorie diet, and an increase in PPARgamma activi...

A novel oligo(p-phenylenevinylene)(OPV)-fullerene dyad, with strong intermolecular pi-pi interactions between the donor groups, led to improvements in the fill factor and power conversion efficiency of dyad-based solar cells of up to 0.44 and 1.28%, respectively, which are the highest values reported for dyad-based solar cells to date.
