The threats posed by chemical and biological weapons can be considered as significant even in these days. Due to the fact that infectious and toxic warfare agents are relatively simple and cheap to produce they are known as the “poor man’s nuclear bomb". They could become dangerous devices with a dreadful effect when they fall into the hands of terrorist groups and aggressive powers. After revi...

Because power requirements for hand-held applications vary widely with product use, no single "best" power source exists for these applications. A device used intermittently is more concerned with no-load quiescent current than with full-load efficiency, and so may operate satisfactorily with alkaline batteries. Cell phones, on the other hand, must contend with high peak loads and frequent use....

Nicaraguan smallholder cooperative leaders working in partnership with a California-based small-scaleroasting company pioneered an alternative approach to confronting the post-1999 coffee crisis. They builtcoffee tasting laboratories and integrated grassroots organizing efforts to create a national smallholdercooperative association that dramatically improved the quality, consistenc...

1.0 INTRODUCTION We have developed a new multifunctional hand mechanism in the hopes of providing a new mechanism that will have superior function over today’s single degree-of-freedom (DOF) mechanisms and yet be robust enough to be clinically viable. There have been a multitude of multifunctional hands built, all of which have failed to find clinical application as an artificial hand replaceme...

This paper deals with various ways of controlling an electrically powered wheelchair beyond the usual method involving a manual joystick. The main focus is on the newest version of HaWCoS – the ”HAnds-free Wheelchair COntrol System” – allowing persons with severe disabilities to reliably navigate a power wheelchair without the need to use the hands. All the user has to do is to produce a sequen...

Massage has been widely applied to improve health and reduce stress. However, the performance difference between hands-on treatment and treatment by mechanical devices has been little mentioned. Therefore, the main aim of this paper is to investigate a subject's EEG performance under massage treatment applied by hand and treatment applied by mechanical devices. Massage was applied to four acupo...

The aim of this study was to compare the effects of grab rail position, orientation, and number of hands used on the kinetics of assisted sit-to-stand transfers. Participants were 12 able-bodied older adults between the ages of 69 and 88 years. While each one performed the sit-to-stand transfer, a motion analysis system with 9 cameras recording at 60 Hz tracked the 3-D trajectories of retrorefl...

This paper describes the integration of modern and traditional obstetric practices in a provincial hospital in the Maithili-speaking area of southern Nepal. The doctors and nurses consciously distance themselves from the traditional practices of their obstetrical patients, whom they view as 'ignorant'; but because hospital resources are insufficient to impose the normative form of modern medica...
