The evolution from an information-based economy to a knowledge-based society requires higher education to produce intellectual outputs to match market and society needs by adjusting its educational process and praxis. Curriculum, as a core factor in refining this process, is therefore a key part of the transformation. Practices of Knowledge Management (KM) or Supply-Chain Management (SCM) have ...

In this report we present our progress of the NRA 02-OSS-01 project on the development of a prototype Dust Particle Analyzer (DPA) and its performance under simulated Martian atmospheric conditions. Both theoretical analysis assuming the predicted environmental conditions of Mars and experimental data on the development of the DPA show that the instrument has an excellent potential for its appl...

Measurements provided by Next Generation Weather Radar and operational thunderstorm monitoring instruments at the Kennedy Space Center Air Force Eastern Range have been examined to determine initial electrical development of 13 isolated, air mass thunderstorms. The same were used examine surface potential gradient prior following long, horizontal discharges that propagated into area. motivation...

Arsenic is a carcinogen with transplacental activity that can affect human skin stem cell population dynamics in vitro by blocking exit into differentiation pathways. Keratinocyte stem cells (KSC) are probably a key target in skin carcinogenesis. Thus, we tested the effects of fetal arsenic exposure in Tg.AC mice, a strain sensitive to skin carcinogenesis via activation of the v-Ha-ras transgen...

In this perspectives paper, we identify major challenges for space crop production: altered convection in the microgravity environment, scheduling and logistics, crew time need advanced automation, robotics, modeling, machine learning. We provide an overview of existing production gaps identified by Kennedy Space Center (KSC) team discuss efforts current development NASA projects to address the...

Resonant and nonresonant intermolecular vibrational energy transfers in KSCN/KSC(13)N/KS(13)C(15)N aqueous and DMF solutions and crystals are studied. Both energy-gap and temperature dependent measurements reveal some surprising results, e.g. inverted energy-gap dependent energy transfer rates and opposite temperature dependences of resonant and nonresonant energy transfer rates. Two competing ...

A systematic method for calculating higher-order corrections of the relativistic semiclassical fixed-energy amplitude is given. The central scheme in computing corrections of all orders is related to a time ordering operation of an operator involving the Van Vleck determinant. This study provides us a new viewpoint for quantization. PACS 03.20.+i; 04.20.Fy; 02.40.+m Typeset using REVTEX ∗e-mail...

This paper provides an overview of the Spaceport Technology Center initiative at NASA’s Kennedy Space Center (KSC). The Spaceport Technology Center initiative encompasses a variety of research and development efforts designed to provide safe, cost-effective access to space and to enable extended space exploration. Spaceport technologies are recognized as critically important to achieving the ae...
