A class of RC active filters in which the DC offset of the operational amplifier (op-amp) is completely absent from the filter output [1]. Individual filter configurations (Low Pass, High Pass, Band Pass, Band Stop, All Pass) are discussed and...
Sleep apnea syndromes; Overweight persons--Health and hygiene; Obesity
Overweight and obesity is a major contributing factor in an estimated 70% of all obstructive sleep apnea (OSA) cases. Approximately five percent of the adult population has OSA, and the numbers continue to soar with the rising prevalence of...
Naja kaouthia is a significant species because it feeds primarily on agricultural pests, causes human mortality, and is commercially exploited. Understanding the life history and demography of harvested populations is essential to providing...
The purpose of this study was to determine the effects of acute glutamine supplementation on maximal performance and recovery from high-intensity exercise. In a placebo-controlled, crossover study, seven (six males and one female) healthy subjects...
In 2003, Wilson Creek running through Bernheim Arboretum and Research Forest in central Kentucky was restored to its original winding path through a valley field. Early 20th century settlers had previously redirected this creek to run a straight...
General. – The Characaeae is the only extant family of an ancient and unique group of nonvascular aquatic plants which are classified as a separate division, the Charophyta (Groves and Bullock-Webster, 1920; Zaneveld, 1940; Imahori, 1954; Bold,...
Sex offenders--Psychology; Sex offenders--Research
Based primarily on theory, it is suspected that violent and non-violent sex-offenders can be differentiated by their psychopathic profile, as measured by the Psychopathy Checklist-Revised (PCL-R; Hare, 1991). There is some concern that current...
We formulate an integro-difference model to predict the growth and spatial
spread of a perennial plant population with an age-structured seed bank. We allow
the seeds in the bank to be of any age, producing an infinite system of equations.
The...
A k-term quasi-progression of diameter d is a sequence {Xl,... ,xk} for which there exists a positive integer l such that l < Xi-Xi-1 < l+d, for all i = 2, ... ,k. Quasi-progressions may be thought of as arithmetic progressions with a certain...
It has been shown that GSK3 β plays a critical role in the inflammation response by differentially regulating MyD88-dependent pro- and anti-inflammatory cytokines production in TLR4-stimulated innate immune cells. The work included in this...
This study compared brief, single sessions of physical activity (PA, self-paced treadmill walking) and relaxation/meditation (R/M, the "Body Scan") on positive and negative affect and anxiety measures in female undergraduates. Both were...
The dental pathogen A. actinomycetemcomitans, a Gram- negative organism, has been associated with aggressive forms of periodontitis. A. actinomycetemcomitans requires iron to grow. In the host, iron-binding proteins such as transferrin,...
Estimating and analysis of deformation, either rigid or non-rigid, is an active area of research in various medical imaging and computer vision applications. Its importance stems from the inherent inter- and intra-variability in biological and...
Interactions between chemokines and their receptors are involved in organ- specific homing and propagation of metastatic breast cancer (BrCa) cells. BrCa cells express higher levels of CXCR4 and CXCR7 mRNA and cell surface protein, than normal...
This study explored the predictive relationships of teacher efficacy, teacher knowledge, and teacher practices with student achievement. More specifically, secondary mathematics teachers' efficacy beliefs, geometry knowledge for teaching, and the...
Aims. The primary aim of this randomized, blinded, controlled clinical trial was to compare the percent root coverage obtained using acellular dermal matrix allograft and connective tissue graft using the coronally positioned tunnel technique 4...
Iron oxide, Fe2O3, is a promising material for water splitting reaction using solar
energy due to its stability and optimal bandgap of 2 eV. Even the recent efforts, however,
using Fe2O3 thin film materials reported low efficiencies due to poor...
The research problem presented herein involved the
structural determination of several a,~-unsaturated acids
and esters. The solution to this problem was sought in the
nuclear magnetic resonance (n.m.r.) spectra of these compounds.
The n.m.r....
Griffithsin (GRFT) is a carbohydrate binding protein derived from the red alga Griffithisia sp. that has been shown to effectively interfere with the cellular attachment and infectivity of a number of viruses, including HIV-1. However, it is...
Copper--Physiological effect; Copper in the body; Heart--Hypertrophy
Previous studies have shown that copper (Cu) supplementation at physiologically relevant levels reverses cardiac myocyte hypertrophy induced by phenylephrine (PE), and that this effect was VEGF-dependent. Yet, the amount of VEGF in the media was...
