in this paper we have down three theoretical study by using monte carlo simulation and mm+,amber and opls force field. the calculations were carried out using hyper chem professional,release 7.01 package of program. first we have studied the interaction of h2 molecule and he atomwith single-walled carbon nanotube at different temperature. for doing this study we placed h2 andhe in the center an...

BACKGROUND AND PURPOSE The Scandinavian Sarcoma Group (SSG) XIV protocol is based on experience from previous SSG trials and other osteosarcoma intergroup trials, and has been considered the best standard of care for patients with extremity localized, non-metastatic osteosarcoma. We analyzed the outcome in 63 consecutive patients. Patients and methods From 2001 through 2005, 63 patients recruit...

An experiment was designed and carried out to study the friction deformation of carbon fibre tow under sliding transverse orientation fibres. A continuous frictional force measured in reciprocal tests over a length about one width tow, as well incremental 4 mm with stop after each millimetre measure topography contact glass plate. Although coefficient depended on initial state first millimetres...

We examine the design of regulatory policy to induce electric utilities to deliver the surplus-maximizing level of energy efficiency services, e∗. The rebound effect (whereby increased energy efficiency stimulates the demand for energy) typically renders revenue decoupling insufficient in this regard. The additional financial incentive required to induce e∗ is shown to vary with such factors as...

This paper argues that a cost/benefit-type economic analysis of whether or not to prohibit euthanasia should not be undertaken by health services managers unless ethical issues have been resolved to a particular conclusion. A conclusion on ethical grounds in favour of the prohibition of euthanasia renders the consideration of economic criteria redundant. The case of the German euthanasia progra...

End-to-end network measurement tools are gaining increased importance in many Internet services. These tools were designed, however, without prior security consideration which, given the current adversarial Internet, renders their extracted network estimates questionable. In this paper, we highlight the major security vulnerabilities of existing end-to-end measurement tools and we sketch possib...

This paper presents the use of haptic devices in teleoperation systems with motion restrictions during robot teleoperation in order to provide the operator with increased awareness and better feeling of immersion, hence, improving his ability to perform complex tasks. The use of wave variables in the proposed system renders passive the communication channel, and moreover the new packet switched...
