In this study, the activity, stability and performance of carbon supported platinum (Pt/C) electrocatalyst in cathode and carbon supported Pt and ruthenium (PtRu/C) electrocatalyst in anode of direct methanol fuel cell (DMFC) were studied. The Pt/C and PtRu/C electrocatalysts were prepared by impregnation reduction method. The β-D-glucose was used as protection agent to reduce the particle size...

In this research, the evolutionary algorithm is applied to behavior learning of an individual agent in the multi-agent robot system. Each agent robot is given two behavior duties both collision avoidance from the other agent and target (food point) reaching for recovering self-energy. In this paper, we carried out the evolutionary simulation of the cooperative behavior creating an environmental...

Microcapsule technology was used to encapsulate the prepared fire extinguishing agent and attach it surface of lithium-ion batteries. This work creates a new battery security protection strategy, can be extended safety design other

In the present issue of Critical Care, an article by Okumura and colleagues has been published on the problem of secondary contamination following chemical agent release [1]. The authors' draw on first-hand experience [2–5] of the secondary contamination experienced during the Tokyo sarin release in 1995. This experience is important, both for the care of contaminated patients and for the safet...

Abstract: Background: Recently, emulgel has emerged as a potential hydrophobic drug delivery method. Therefore, this study aims to evaluate the phytochemical content of Oryza sativa extract and develop an formulation using Carbapol 940 gelling agent. Materials Methods: The emulsion was placed in gel basis after preparation formulations were evaluated for their rheology, pH, spreading coefficien...

-The penetration of DGs would drastically affect the traditional distribution power system fault current level and the characteristics of fault currents, consequently, the traditional protection arrangements developed in radial systems are difficult in coordination, and also the reclosing scheme would be affected. With the rapid developments in distribution system automation and communication t...

Today, web attacks are increasing in frequency, severity and sophistication. Existing solutions are either hostbased which suffer deployment problems or middlebox approaches that can only accommodate certain security protection mechanisms with limited protection. In this paper, we propose four design principles for general middlebox frameworks of web protection, and apply these principles to de...

Purpose – Agent technology has generated a lot of interest in recent years, including mobile agent technology with its advantage of being able to support mobility, which can reduce network latency and dependency on network availability. Therefore, a number of mobile agent-based e-commerce applications have been constructed. Mobile agent-based e-marketplaces are e-commerce trading platforms whic...
