Facilitating and Limiting Factors Relative to Learning to Cope With the Added Role of Student for Adults Who Return to School on a Part-Time Basis in Business Programs
This exploratory study is one of several studies currently looking at the relationship between perceived functionality of role behavior, related learning activities, and related change patterned on the methodology used by Farmer and Knox (1977). The related change in this study is perceived change …

Factors Affecting Changes in Adult and Continuing Education Programs in Private, Liberal Arts Colleges
… these program changes and (2) facilitating and limiting factors. The study emphasized the development of new understandings rather than the testing of existing theories because of the emphasis on existing natural settings and the lack of theory relative to recent changes in continuing education …

Atomic layer deposition and electrochemical characterization of TiO2 as a potential candidate for a photoanode protective layer
… in aqueous solutions is one of its main limiting factors. TiO2 film (~6 nm) were deposited on the anode surface, using atomic layer deposition and plasma enhanced atomic layer deposition (ALD), to act as corrosion protection and to passivate the electrode surface along with a 5 nm Nickel …

Developing tools to identify factors that limit production in coastal marshes
… techniques. Current methods for identifying factors that limit productivity in marshes are too time-consuming or expensive for wide-spread, regular use. Critical values of elemental concentrations in plant tissue are widely used to diagnose mineral deficiencies and toxicities in agricultural …

Packaging of the MIT Microengine
… metal-to-silicon connections. The three strength-limiting factors found in metal-to-glass-to-silicon seals were the existence of voids in the glass, the lack of wetting of the glass on the silicon, and the residual stress in the silicon due to thermal expansion mismatch with the glass. Sessile …
