noise is defined as unwanted or objectionable sound. human susceptibility to noise varies in terms of intensity, altitude, timbre of sound, personal sensibility, age, and history of ear disorder. noise pollution which is the result of heterogeneous and uncontrolled developments of cities is one the serious problems in large cities of iran. although noise pollution in kerman (located in southeas...

The actions of endothelin on the contractile and twitch configuration characteristics of rat and rabbit papillary muscles were evaluated before and after endocardial endothelium removal. In rabbit papillary muscles, endothelin produced a dose-dependent (10(-11) to 10(-7) M) increase in tension (T) (from 2.7 +/- 0.2 to 8.9 +/- 0.7 g/mm2, p less than 0.01), dT/dt, and Vmax (from 1.14 +/- 0.03 to ...

The aim of the present paper is the study of the entropic elasticity of the dsDNA molecule, having a cristallographic length L of the order of 10 to 30 persistence lengths A, when it is subject to spatial obstructions. We have not tried to obtain the single molecule partition function by solving a Schödringer-like equation. We prefer to stay within a discretized version of the WLC model with an...

We experimentally tested the hypothesis that accumulations of dietary compounds such as carotenoids or UVabsorbing mycosporine-like amino acids (MAAs) protect against natural levels of ultraviolet radiation (UVR). A calanoid copepod, Leptodiaptomus minutus, was collected from a relatively UV-transparent lake in Pennsylvania where levels of copepod MAAs and carotenoids vary during the year (MAAs...

By simple modification of the functional groups on boron–nitrogen-containing skeleton, energy level highest occupied molecular orbital (EHOMO) emitters can be easily adjusted. Blue-emission derivatives are developed, which capable showing small full width at half maximums and high photoluminescence quantum yields. Blue thermally activated delayed fluorescence (TADF)-assisted organic light-emitt...

The present study provides the first indication of life-history traits, including, population structure, growth pattern, condition factor, form factor (a3.0), size at sexual maturity (Lm), natural mortality (MW) and optimum catchable length (Lopt), three Ambassid (Chanda nama, Parambassis lala ranga) fishes from Mathabhanga River in southwest Bangladesh. A total 370 individuals were occasionall...

The set C(G) of closed subgroups of a locally compact group G has a natural topology which makes it a compact space. This topology has been defined in various contexts by Vietoris, Chabauty, Fell, Thurston, Gromov, Grigorchuk, and many others. The purpose of the talk was to describe the space C(G) first for a few elementary examples, then for G the complex plane, in which case C(G) is a 4–spher...

To the Editor: An indole is not an indole when it is a naphthalene derivative! We routinely measure 5-hydroxyindoleacetic acid (5HIAA) by a longestablished method using nitrosonaphthol, as first described by Udenfriend in 1955 [1], but with various modifications to improve specificity [2]. The profession’s elder statesmen may well recall the method of Hanson and Serin [3] using Erlich’s reagent...

Introduction: While the minimum number of directions required for robust diffusion tensor imaging (DTI) has been extensively studied [1-4], the equivalent studies have not been performed for high angular resolution diffusion-weighted imaging (HARDI) methods. This is due in part to the fact that many HARDI methods are available, each with their own requirements and parameters, making it difficul...

ABSTRACT We investigate the observational properties of a hydrogen-deficient superluminous supernova (SLSN) SN 2020ank (at z = 0.2485), with help early phase observations carried out between –21 and +52 d since g-band maximum. Photometrically, is one brightest SLSN ($M_{\mathrm{ g,peak}}\, \sim$ –21.84 ± 0.10 mag), having fast pre-peak rising post-peak decaying rates. The bolometric light curve...
