Learners’ Performance in Physical Sciences Using Laboratory Investigations

The Rat in Laboratory Investigations

The fact that it is possible to compile a list of 6,029 entries pertinent to such a new subject as Aviation Medicine reflects clearly the manner in which the problems presented to medical science by the demands of aviation cut across almost all lines of medical and biological science. The forces of destruction have, of course, but accentuated the need for an understanding of those problems of m...

Online Laboratory Investigations

Critical Care Medicine www.ccmjournal.org e65 Objective: Cyclic recruitment and derecruitment of atelectasis can occur during mechanical ventilation, especially in injured lungs. Experimentally, cyclic recruitment and derecruitment can be quantified by respiration-dependent changes in Pao2 (ΔPao2), reflecting the varying intrapulmonary shunt fraction within the respiratory cycle. This study inv...

Audit of Advanced Laboratory Investigations.

BACKGROUND Advanced laboratory investigations at reference laboratories play a key role in the diagnosis of the disease, but misuse of this precious and expensive tool may misguide the physician in patient management. This study was carried out as an audit of investigations performed at a reference laboratory, in order to assess their cost effectiveness, to identify various errors, the degree o...

Laboratory Investigations of ImpactGenerated Plasma

The production f magnetic fields by hypervelocity meteoroid mpact has been proposed toexplain the presence of palcomagnetic fields in some lunar samples a well as on the lunar surface. Impact-generated magnetic fields also may be significant for the palcomagnetic re ord on a variety of cratered surfaces inthe solar system, such as the Moon, Mercury, Phobos, and asteroids. Previous experiments w...
