In any closed environment considered, it can be seen that the acoustic parameters are inherently not constant over entire area considered. a environment, is ideally preferred to maintain as so there exists better quality of sound leading auditory perception with respect audience. Practically, some like reverberation time and clarity do strictly pertain pattern obtained theoretically. this paper...

Background: D-Phenylglycine aminotransferase (D-PhgAT) is highly beneficial in pharmaceutical biotechnology. Like many other enzymes, D-PhgAT suffers from low stability under harsh processing conditions, poor solubility of substrate, products and occasional microbial contamination. Incorporation of miscible organic solvents into the enzyme’s reaction is considered as a solution...

Abstract Background Results of previous trials about PFO closure as a treatment for migraine are still doubtful and inconclusive. We sought to evaluate the long–term (>10 years) effectiveness by means patent foramen ovale (PFO) closure. Methods From 2006 2010, 86 patients (68 female, mean age 40.0 ±3.7 with disabling, medication–refractory were enrolled in prospective study over 48–month...

The movement of a wheelchair with manual propulsion depends on the kinematics human body and forces exerted by muscles. To design innovative systems, biomechanical parameters resulting from interaction in this anthropotechnical system must be formalised. research objectives were thus adopted: an analysis wheel angle rotation hand movement’s trajectory mathematical formalisation described as fun...

We compute the light-hadron mass spectrum at b55.7 using the O(a)-improved Sheikholeslami-Wohlert fermion action with two choices of the clover coefficient: the classical value c51 and a mean-field or tadpole-improved estimate c51.57. We compare our results with those of the GF11 Collaboration who use the Wilson fermion action (c50). We find that changing c from zero to 1 and 1.57 leads to sign...

This paper studies the impact of public infrastructure on economic performance. We employ three di¤erent methodologies to estimate the returns to public investment. First, we relate growth in total factor productivity to accumulation of public capital. Second, we assess the role of public capital as an input to production. Third, we evaluate the reduction in costs that can be attributed to the ...

This paper constructs and estimates the demand for international tourism for the Italian Province of Sassari. The sample period under estimation is from 1972 to 1995. Three dynamic models are estimated at monthly, annual and quarterly data frequencies. Similarities and differences are explored amongst the three models, using recently developed econometric techniques. A “premodelling” data analy...
