of Excellence, for DRS Power and Controls Technology, Inc., in Fitchburg, Massachusetts. His career has been centered on development and integration of technologies to improve power plant system performance in nuclear powered submarines and industrial (petrochemical) applications. Mr. Smith’s experience spans the design, construction, test, and delivery of all nuclear propulsion plant equipment...

The Idaho National Engineering and Environmental Laboratory (INEEL) is an 890 square mile multiprogram Department of Energy (DOE) laboratory in southeastern Idaho. Over the past 50 years, the laboratory has witnessed many significant scientific advances, particularly in the areas of nuclear propulsion, nuclear reactor safety and design, and waste management. As a result of this long history, va...

An analytical model is developed to study the viscoelastic micropolar fluid convection from an inclined plate as a simulation of electro-conductive polymer materials processing with nonlinear temperature. Jeffery’s viscoelastic model is deployed to describe the non-Newtonian characteristics of the fluid and provides a good approximation for polymers. Micro-structural is one of the characteristi...

The authors completed those propulsion system for microsatellite based on the SAFETY FIRST policy and EFFECTIVE COTS, by the beginning of 2008, which can work as both monoand bi-propellant propulsion system and attain wide-range impulse bit and total impulse by switching the monoand bi-propellant modes. We have been devoting ourselves to develop an upgraded version of the propulsion system sice...

Manual wheelchair propulsion places considerable physical demand on the upper extremity and is one of the primary activities associated with the high prevalence of upper extremity overuse injuries and pain among wheelchair users. As a result, recent effort has focused on determining how various propulsion techniques influence upper extremity demand during wheelchair propulsion. However, an impo...

Over 2500 active satellites are in orbit as of October 2020, with an increase ~1000 smallsats the past two years. Since 2012, over 1700 have been launched into orbit. It is projected that by 2025, there will be 1000 per year. Currently, these do not sufficient delta v capabilities for missions beyond Earth They confined to their pre-selected and most cases, they cannot avoid collisions. Propuls...

The role of the tachykinin neurokinin (NK)(2) receptors on rabbit distal colon propulsion was investigated by using two selective NK(2)-receptor antagonists, MEN-10627 and SR-48968. Experiments on colonic circular muscle strips showed that contractile responses to [beta-Ala(8)]NKA-(4-10) (1 nM-1 microM), a selective NK(2)-receptor agonist, were competitively antagonized by MEN-10627 (1-100 nM),...

BACKGROUND The hand pattern used during manual wheelchair propulsion (i.e., full-cycle hand path) can provide insight into an individual's propulsion technique. However, previous analyses of hand patterns have been limited by their focus on a single propulsion condition and reliance on subjective qualitative characterization methods. The purpose of this study was to develop a set of objective q...
