Blackberries are very perishable with a limited shelf life due to high metabolic activity and susceptibility mechanical damage microbial attack. The effect of edible coatings (EC) based on candelilla wax (CW) guar gum (GG) the quality, life, bioactive-compounds content antioxidant blackberries stored at 25 ± 2 °C for 6 days, was evaluated. All EC contained GG (0.4%) gallic acid (GA)(0.06%); EC1...
We have previously demonstrated that optical phonons and polaritons in simple compound semiconductors, e.g. , GaP, possess dephasing times in the picosecond and femtosecond time scales. ' In high-purity materials the source of the dephasing is dominated by three-particle anharmonic interactions. Others have demonstrated that longitudinal acoustic (LA) and transverse acoustic (TA) phonons decay ...
abstract the variables affecting the nature of reading comprehension can be classified into two general categories: reader’s variables, and text variables (alderson, 2000). despite the wave of research on vocabulary knowledge as reader’s variable, the role of this knowledge in c-test as a text-dependent test and its interaction with lexical cohesion of the test as a text feature has remained a...
The experimental study of the electron cloud dynamics and mitigation techniques is one of the main objectives of the CESR Damping Ring Test Accelerator (Cesr-TA) program. Shielded pick-up buttons are a relatively simple diagnostic device for obtaining time-resolved information on the electron cloud density. They have been already successfully employed on the SPS at CERN [1], although with diffe...
the purpose of this study was to examine the english language needs of medical students at tehran university of medical sciences . analysis of the needs took place for three groups: 320 undergraduate students, 30 postgraduate students and 20 university instructors. a triangulation approach to collect data was used in which a combination of the quantitative (using the questionnaires) and qualita...
the use of natural compounds to control plant pathogens lead to reduction in using fungicides. chitosan with duble effects, control pathogenic microorganisms and activate inducing defence responses, has been shown to be a reliable nontoxic material in the plant-pathogen interaction. the aim of this research was to consider the effects of chitosan and calcium chloride on decay and quality attrib...
in recent years, there has been a growing interest among researchers to investigate the relationship betweenteacher self-efficacy and classroom behavior management, especially students misbehavior. therefore, this study aimed to comparatively investigate english and arabic teachers’ use of different behavior managementstrategies, their self-efficacy, and their success in an iranian context. th...
In this paper, we show for the first time that ultrafast light illumination can induce an unusually broad transient optical absorption (TA), spanning of ≈ 200 nm in the sub-bandgap region of chalcogenide GeSe2 thin films, which we interpret as being a manifestation of creation and annihilation of light induced defects. Further, TA in ultrashort time scales show a maximum at longer wavelength, h...
I use Bousso’s causal diamond measure to make a statistical prediction for the dark matter abundance, assuming an axion with a large decay constant fa ≫ 10 GeV. Using a crude approximation for observer formation, the prediction agrees well with observation: 25% of observers see less dark matter than we do while 75% of observers see more dark matter. Larger values of the dark matter ratio are di...
The yeast protein Dom34 is a key component of no-go decay, by which mRNAs with translational stalls are endonucleolytically cleaved and subsequently degraded. However, the identity of the endoribonuclease is unknown. Homologs of Dom34, called Pelota, are broadly conserved in eukaryotes and archaea. To gain insights into the structure and function of Dom34/Pelota, we have determined the structur...
