Statistical Mechanics Of Conformational Transitions In Biopolymers., Rachid Charbel Maroun
Statistical Mechanics Of Conformational Transitions In Biopolymers., Rachid Charbel Maroun
LSU Historical Dissertations and Theses
Recently extended theoretical methods and existent experimental methods have been employed for the determination of conformational-dependent properties of polymers of biological interest like synthetic polyamino acids, natural polypeptides and proteins. Calculation of theoretical properties, like for example average helical content and average helical length, as derived from the configuration partition function has been achieved by making use of the Rotational Isomeric State approximation through modifications and innovations of a nearest-neighbor interaction version of the Zimm-Bragg model of helix-coil transitions as presented in a matrix format suitable for use in an electronic computer. The scope of the theory allows for the …
The Mediational Role Of Social Influence In The Perception Of Exertion., Charles Jeffrey Hardy
The Mediational Role Of Social Influence In The Perception Of Exertion., Charles Jeffrey Hardy
LSU Historical Dissertations and Theses
Two experiments are reported that investigate the mediational role of social influence in the self-perception of exertion. In Experiment 1, subjects performed three 15 min trials on a cycle ergometer at 25%, 50%, and 75% of VO(,2) max, both in the presence of another performer (a coactor) and alone. The results indicated that subjects reported lower RPEs when performing with another, particularly at the moderate (50%) intensity. In Experiment 2, subjects performed one 15 min trial at 50% of VO(,2) max, both alone and in the presence of another performer (coactor) exhibiting nonverbal "cues" that the work was either extremely …
The Effects Of Acute Dehydration On The Anaerobic Threshold During Incremental Cycle Ergometer Exercise., Penelope England
The Effects Of Acute Dehydration On The Anaerobic Threshold During Incremental Cycle Ergometer Exercise., Penelope England
LSU Historical Dissertations and Theses
Much of the previous research concerning dehydration and performance has centered around prolonged submaximal work while seemingly little attention has been focused upon short term incremental exercise. Numerous investigators have suggested that dehydration may alter carbohydrate metabolism in muscle. Theoretically, altered glycolytic flux in exercising muscle could result in a change in the rate of blood lactate (La) accumulation, and thus shift the anaerobic threshold. Anaerobic threshold (AT(,La)) has been formally defined as the oxygen uptake (V(,O(,2))) at which there is a systematic increase in blood La. Additionally, the AT(,La) has been estimated from a nonlinear increase in expired ventilation …
Rydberg States Of Polyatomic Molecules: Multichannel Approaches For The Simple Halides., John Arthur Dagata
Rydberg States Of Polyatomic Molecules: Multichannel Approaches For The Simple Halides., John Arthur Dagata
LSU Historical Dissertations and Theses
A major portion of the high resolution photoabsorption spectrum of methyl iodide in the region between 49000 and 77000 cm('-1) has been analyzed by methods based on multichannel quantum defect theory (MQDT). Nearly all bands in this energy region can be assigned as members of molecular rydberg series which converge to the two lowest ionization limits of the molecule. However, it is also found that the Born-Oppenheimer separability of the totality of electronic surfaces is not nearly as complete as might be implied by the above results. Specifically, a nonrydberg, valence electronic state is shown to interact with the rydberg …
