ourselves. While the emergence of infections such as trated, and some of the few figures that are included smallpox has been linked to the development of the better explained. Even the novels of B.B. Jorden manage first numerically significant human communities, there to include a few drawings to illustrate, for example, the seems to be little indication that these or other virus life cycle of ...

The Arp2/3 complex is a powerful nucleator of actin filaments when activated. A recent study has now revealed that this complex is not only subject to positive control but that there also exists a brake on its activity. This brake can suppress both the basal activity of the Arp2/3 complex as well as its activation by nucleation-promoting factors.

The statistical data published by National Police Agency, Taiwan, indicated that the motorcycle induced the highest accident rate, and drunk driving ranked first among the traffic fatality causes in 2007. The high traffic accident rate was attributed to the alcohol decaying driver reaction and the increase of frequency of using motorcycle in daily life as the car parking space and driving cost ...

in this paper, the amount of wasted heat from different parts of a 12 liter compression ignition engine and their potential for waste heat recovery were investigated. then, two-stage configuration of organic rankine cycle was introduced for simultaneous heat recovery from exhaust gases and coolant. finally, parameters like hybrid generated power, engine thermal efficiency and brake specific fue...

Intracellular viscosity is a fundamental physical parameter that indicates the functioning of cells. In this work, we developed a simple boron-dipyrromethene (BODIPY)-based probe, BTV, for cellular mitochondria viscosity imaging by coupling a simple BODIPY rotor with a mitochondria-targeting unit. The BTV exhibited a significant fluorescence intensity enhancement of more than 100-fold as the so...

Over the years designers have developed various combined brake-accelerator pedals in an effort to eliminate the operator’s risk of pressing the wrong pedal as well as to reduce his or her reaction time in braking. The goal of this study was to highlight problems that drivers may face when they switch between pedal systems. Eighteen male and female drivers varying in age participated in the stud...

aIn the present study a 4-stroke 5hp diesel engine was tested with Diesel oil plus cottonseed oil blends. The blends in different proportions (10 to 50 percent by volume) were tested at constant speed of 1500 rpm. The said engine is operated at different loads and characteristics like Brake power, Brake thermal efficiency, specific fuel consumption etc. Engine performance for blends resulted in...

In automatic highway systems, a faster response and a robust braking system are crucial part of the overall automatic control of the vehicle. This paper describes electromagnetic brakes as a supplementary system for regular friction brakes. This system provides better response time for emergency situations, and in general keeps the friction brake working longer and safer. A modified mathematica...
