Background and aims Traffic noise barriers are the most important measure to control the environmental noise pollution. Diffraction from top edge of noise barriers is the most important path of indirect sound wave moves towards receiver.Therefore, most studies are focused on improvement of this kind. Methods T-shape profile barriers are one of the most successful barrier among many dif...
abstract treating soil with insecticides is thought to be an effective method for termite control. speed of action and repellency of insecticides are important factors for discussing their barrier effects as soil-treatment termiticide. microcerotermes diversus (silvestri) is the most economically destructive termite in structures in ahwaz region, because the species feed on anything with cellul...
Background: Dielectric barrier discharge (DBD), a source of non-thermal plasma, is used in surface decontamination. Objective: To study the effect of DBD plasma treatment, we evaluated the effect of plasma exposure time on inactivation of Bacillus subtilis. Results: Applying the DBD plasma to the culture of B. subtilis caused complete sterilization of the surface without any thermal effects. In...
A theoretical study of resonant tunneling in multilayered GaAlAs/GaAs structures are presented. The spectrum of resonant energies and its dependence on the barrier structure are analyzed from calculated profiles of barrier transparency versus energy, and from current voltage characteristics computed at selected temperatures and Fermi levels. The present formalism is based on the effective mas...
in this study, scour of mashkid bridge pier located in mashkid river of saravan county has been studied and to measure the scour rate, the numerical model hec-ras 4.0 has been used. upon selection of mashkid river as the case study and whereas the studied zone is important with respect to the climatic conditions and showery monsoon raining and flowing the great and destructive floodwaters, ther...
background: this study was designed to assess the microleakage of glass-ionomer (gi), mineral trioxide aggregate (mta), and calcium-enriched mixture (cem) cement as coronal orifi ce barrier during walking bleaching. materials and methods: in this experimental study, endodontic treatment was done for 70 extracted human incisors without canal calcifi cation, caries, restoration, resorption, or cr...
as milk is a liquid compound, it needs containers at every stages of movement. the first significant development in milk packaging created at the end of nineteenth century. the flavor changes and shelf life of pasteurized milk and ultra pasteurized milk are affected by processing conditions, packaging materials and microbial growth. off-flavor is an effective factor on reduction of milk quality...
