Some supraspinal structures exert a powerful but selective modulation upon spinal reflexes and sensory transmission. In most cases the effect was, however, elicited by electrical stimulation of supraspinal sites 4-6. In spite of the fact that photic or auditory stimulation is capable of eliciting reflex pyramidal discharge1, 3 or ventral root discharge after pyramidectomy 3, the effect of this ...

air conditioning refrigerant r134a has value of global warming potential (gwp) 1300, which is much higher than mac directive (gwp below 150) passed in july 2006. this prompted a search for alternative refrigerant with gwp value less than 150. r1234yf is a new refrigerant which has lower gwp value of 4. effect of blower speed has been compared and flammability issue of r1234yf has been addressed...

Water limitation is one of the main factors that influence germination process, affecting crop establishment. Thus, alternatives capable lessening such effects become great relevance. The aim this study was to evaluate effect ascorbic acid dosage on This aimed marandu grass seeds submitted different water conditions. After establishing immersion time for seed conditioning based soakingcurve, ex...

Drought escape and dehydration avoidance represent alternative strategies for drought adaptation in annual crops. The mechanisms underlying these two strategies are reported to have a negative correlation, suggesting a trade-off. We conducted a quantitative trait locus (QTL) analysis of flowering time and root mass, traits representing each strategy, in Brassica napus to understand if a trade-o...

The purpose of this investigation was to cross-validate the ithlete™ heart rate variability smart phone application with an electrocardiograph for determining ultra-short-term root mean square of successive R-R intervals. The root mean square of successive R-R intervals was simultaneously determined via electrocardiograph and ithlete™ at rest in twenty five healthy participants. There were no s...

Background: The coverage of denuded roots represents one of the greatest challenges to periodontal treatment as clinician is not only required to treat disease and improve function but also cope with ever demanding esthetics of patients. Among various techniques used, laterally positioned pedicle graft (LPG) is widely used successfully to cover Miller’s class-I and Class-II recession defects be...

We propose a quasi-Monte Carlo algorithm for pricing knock-out and knock-in barrier options under the Heston (1993) stochastic volatility model. This is done by modifying the LT method from Imai and Tan (2006) for the Heston model such that the first uniform variable does not influence the stochastic volatility path and then conditionally modifying its marginals to fulfill the barrier condition...

Introduction Periodontal regeneration is the reproduction or reconstitution of a lost or injured part of the periodontium so that the form and function of lost structures is restored. Many procedures have been attempted to achieve periodontal regeneration, including root surface conditioning, bone graft placement, guided tissue regeneration (GTR) and growth factor application. Current regenerat...

Peripheral nerve injury results in the activation of a number of transcription factors (TFs) in injured neurons, some of which may be key regulators of the regeneration-associated gene (RAG) programme. Among known RAG TFs, ATF3, Smad1, STAT3 and c-Jun have all been linked to successful axonal regeneration and have known functional and physical interactions. We hypothesised that TF expression wo...

In this paper we consider the application of polynomial root-finding methods to the solution of the tridiagonal matrix eigenproblem. All considered solvers are based on evaluating the Newton correction. We show that the use of scaled three-term recurrence relations complemented with error free transformations yields some compensated schemes which significantly improve the accuracy of computed r...
