cadmium sulfide nanoparticles were grown using wet chemical method by dissolving the reactants ofcadmium acetate and sodium sulfide in the presence of thioglycerol (tg) as capping agent in ethanolsolvent. different nanoparticle sizes and size distribution were obtained through varying the molaritiesof thioglycerol. at higher tg concentration, synthesis provides a nearly monodisperse nanoparticl...

agent oriented software engineering (aose) is an emerging field in computer science  and  proposes some systematic ideas for multi agent systems analysis, implementation and maintenance. despite the various methodologies introduced in the agent-oriented software engineering, the main challenges are defects in different aspects of methodologies. according to the defects resulted from weaknesses ...

The aim of this research is to determine high school students’ cognitive structure regarding cleaning agent via word association test. sample the consists 160 students. A test (WAT) prepared addressed in study was used as data collection tool. Content analysis evaluate obtained from group. Words written by students relation were analyzed elaborately and based on concepts categorized well their ...

tio2 nanoparticles, as a photocatalyst for oxidation of dimethyl methylphosphonate (dmmp) as an organophosphorus simulant of chemical warfare agent, were prepared by using sol-gel method. the prepared nanoparticles were then modified with transition metals in order to decrease the electron-hole recombination and increase the photocatalytic activity. transition metal ions including pt, pd and ni...

Sulforaphane, an isothiocyanate found in broccoli and other cruciferous vegetables. it is an antioxidantand anti-cancer agent, and reduces blood pressure, and also has anti-allergic Effects.In this article, six theoretical methods have been used for calculation of physical parameters insolforaphane and several similar compounds. We calculated physical parameters like atomic charges.energy (AE) ...

In this article, borax was used as the prime agent, and organic boron that cross-linked agent synthesized using adding sodium tartrate. The synthesis response shapes were optimized unmarried factor way. temperature opposition crosslinking time of fracturing fluid appraisal standards to decide boron. cross-linking agent's optimal statuses measured, chemical forcible holdings after with polyvinyl...

Forensic laboratories do not have the infrastructure to process or store contaminated DNA samples that have been recovered from a crime scene contaminated with chemical or biological warfare agents. Previous research has shown that DNA profiles can be recovered from blood exposed to several chemical warfare agents after the agent has been removed. The fate of four toxic agents, sulfur mustard, ...

This paper presents a rigorous evaluation of a novel, distributed chemical plume tracing algorithm. The algorithm is a combination of the best aspects of the two most popular predecessors for this task. Furthermore, it is based on solid, formal principles from the field of fluid mechanics. The algorithm is applied by a network of mobile sensing agents (e.g., robots or micro-air vehicles) that s...
