rust diseases continue to cause significant losses to wheat production around the world. among them, yellow rust caused by puccinia striiformis f. sp. tritici is an important disease that threatens wheat production in most cool environments. host resistance, especially race- nonspecific resistance, is the most economical way to manage wheat stripe rust disease. in this study, the effectiveness ...
Background : Skeletal muscles are composed of various contracted fibrils, which are mainly divided into fast-twitch and slow-twitch. This study aimed to investigate 8 weeks endurance activity on the MEF2 and HDACA4 gene expression in fast-twitch and slow-twitch skeletal muscles in male Wistar rats. Materials and Methods: in order to carry out this study, 20 heads of male Wistar rat...
Identification and tracking of solar coronal loops is key to understanding solar magnetic field. Slow and fast Magnetohydrodynamic oscillation of tracked loops from sequence 171Å extreme ultra – violet images was detected. The method was demonstrated using 171Å images taken by SDO/AIA on 14 August 2010 and 20 January 2012. Two dimensional continuous wavelet transform (CWT) was used to clarify ...
A polarized light imaging technique is introduced that simultaneously captures and unfolds transmittance, fast/slow axes directions and birefringence or linear dichroism from single camera exposures. The technique, based on the rotating polarizer method, is capable of sampling an object through polarizers at four different angles in a single image with the use of an image multiplexer. The range...
Abstract The purpose of the present study, considering the facilitating effect of sound on individual’s cognitive performance was to investigate the effect of music as one of the common audio stimuli on selective attention in children with attention deficit/ hyperactivity disorder. In this research 30 male students with Attention deficit/ Hyperactivity Disorder is selected using the Teacher's ...
the present study aims at identifying, classifying and analyzing collocation errors made by translators of the holy quran into english.findings indicated that collocationally the most acceptablt translation was done by ivring but the least appropriate one made by pickthall.
a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...
The Nav1.1 voltage-gated sodium channel is a critical contributor to excitability in the brain, where pathological loss of function leads to such disorders as epilepsy, Alzheimer's disease, and autism. This voltage-gated sodium (Nav) channel subtype also plays an important role in mechanical pain signaling by primary afferent somatosensory neurons. Therefore, pharmacologic modulation of Nav1.1 ...
the aim of this study was to investigate the effect of different rhythms of music on some central and peripheral fatigue indices in non-athlete young females. for this purpose, 38 healthy female students were randomly divided into three groups: fast music group or exp1 (n=13, m+sd age: 22+2 years), slow music group or exp2 (n=13, m+sd age: 23+2 years) and control group (n=12,m+sd age: 23+2 year...
Previously, the existence of nine types of outward potassium current (IK) was shown. The whole family of IK may be divided into two groups: fast transient currents (f) with time to peak less than 70 ms (at test potential near 0 mV), and slow (s) components (Lukyanenko et al. 1993). The latter were completely blocked by 4-aminopyridine (4-AP) and the former were more sensitive to TEA than slow I...
