The reactivity of men who differed on a measure of cognitive appraisal of masculine gender role stress (MGRS) was compared using the cold-pressor test under conditions of high and low masculine performance challenge. Under conditions of minimal challenge, it was predicted that high and low MGRS men would not differ on react

High feed ingredient prices have increased the use of by-products containing a high proportion of polyunsaturated fatty acids (PUFA) in pig and chicken feeds. This can increase the oxidation of other feed nutrients as well as causing oxidative stress in animals.

Abstract:

Numerous alternatives to fish meal (FM) have been investigated by aquaculture nutritionists in order to reduce aquacultures reliance on this finite and costly resource. Traditional protein alternatives derived from terrestrial plants and animals have shown varying success and limitations. In order to produce effective, least cost feeds new alternative proteins must be investigated. Ethanol yeast (EY), a co-product of bio-ethanol production may be a novel protein source. The increasing capacity of the bio-ethanol industries has made EY an increasingly available commodity. However, no studies h

Abstract:

Young women are known to exhibit a greater incidence of orthostatic hypotension than men. The exact mechanisms for this are unclear and it has been proposed to be related to cardiac filling, peripheral resistance, and/or regional blood pooling. The sexually dimorphic effects of lower body negative pressure (LBNP) or upright posture were investigated throughout this study. Women could experience these changes due to effects of the sex hormones estrogen and progesterone. Chapters 3 and 4 in this thesis investigated the responses of women to LBNP in both the follicular and the luteal phase of the

Abstract:

碩士<br>國立臺北護理健康大學<br>長期照護研究所<br>106<br>In recent years, the number of elderly people living alone in Taiwan has continued to increase substantially. Planning for care services based on the needs of solitary elderly is of considerable importance. In the current long-term care strategy for elderly people living alone, it has been proven by previous literature that catering services can provide them with certain social support. This study treats the care services (including meal delivery and meal sharing) for elderly people living alone in Taipei as a form of social support. The purpose is to expl

Abstract:

Being able to extrapolate interaction values from a database of pullout resistance testing results may possibly help with narrowing down the most suitable reinforcement/fill material combinations for a Mechanically Stabilized Earth wall, thereby reducing the number of tests needed for a design and maximizing the efficiency of the system. The objectives of this thesis include the following: collect and organize a broad collection of data in a way that can assist in preliminary selection of interaction properties for uniaxial geogrids; analyze the collection of data for trends related to geogrid
