To reduce water traffic accident, identification of overloaded ships has been of major importance for enforcing inland river management, especially in some developing countries. Driven by rising oil prices or other economic benefits, the ship overload phenomenon continued to occur in China. Therefore, overloaded ship detection has been of a key factor of shipping safety. This paper presented a ...

plants are potent biochemists; biologically active compounds present in the medicinal plants have always been ofgreat interest to scientists working in this field. thus, the aim of the current study was to screen the antimicrobial activity of acacia nilotica, ziziphus mauritiana, bauhinia variegate and lantana camara against some selected clinical isolated strains. although previous studies hav...

Walking speed is a very important factor in evacuation analysis for human safety. To provide against emergencies such as abandonment of ship due to accident, the authority body required evacuation analysis for passenger ships. To develop a simulation tool for the evacuation analysis, human behavior data for evacuation situations are fundamentally necessary. In this paper, onboard experiments we...

Abstract: A Fuzzy logic control law is presented and implemented for trajectory tracking of multiple under actuated autonomous surface vessels. In this study, an individual unmanned ship is used to be the leader that tracks the desired path; other unmanned ships are used to be the followers which track the leader only by using its position. A fuzzy controller was implemented for the ship leader...

Previously, we showed that 2B4 is a dominant inhibitory receptor in SHIP-deficient NK cells that prevents efficient cytolysis of complex targets. We show in this study that 2B4 deficiency restores homeostatic control and cytolytic function to SHIP-deficient NK cells. However, 2B4(-/-)SHIP(-/-) NK cells still exhibit a profound disruption of their NK receptor repertoire and are compromised for i...

the significant role of insurance in making good the damages arising from different incidents menacing human being is compeletly clear. particularly that, in some areas, in conclusion of rapid development of science and technology and complication of facilities and relations, it appears necessary to protect injured persons against financial consequences resulting from diverse accidents. in this...
