Abstract:

The objective of this study was to determine the leaf water relations, gas exchange, and growth of the bedding plant salvia Salvia splendens 'Bonfire‘ as influenced by moisture stress conditioning (MSC - exposing plants to 4 sublethal dry-down cycles) and potassium (K) nutrition. Plants were fertilized with one of six K rates: 25, 75, 150, 300, 450, and 600 ppm as KCl in experiment one. Seven weeks after seeding plants were subjected to MSC. MSC and increasing K rate resulted in osmotic adjustment and increased cellular turgor potentials. Foliar K content increased as osmotic potentials decrea

While a great deal of research has been directed towards the phenomena of excess post exercise oxygen consumption (EPOC), the effect of thermal stress on EPOC is not well defined. To assess the effect of heat stress on EPOC, seven healthy, active subjects (4 female, 3 male; 23.9 ± 2.0 years of age) performed 4 trials: one control (quiet rest) and one exercise (45 minutes of cycling at 65% VO2max workload) trial in moderate (23° C, 50% humidity) and hot (35° C, 50% humidity) environments.

Abstract:

The first part of this literature review goes over the biological and psychological aspects of stress. The cause of stress can be linked back to a primitive instinct known as “fight or flight.” The “fight or flight” instinct is triggered by several chemical reactions in the body starting from a signal from the amygdala to the sympathetic nervous system. Stress can also be categorized into internal and external stress. Further research links stress to sports. Many studies show that stress coping techniques such as meditation, self-talk, rituals, etc. are beneficial to athletes during competitio

Psychological stress appears to precede instances of auditory hallucinations in those vulnerable to them. This suggests that psychological stress acts on the auditory perceptual system in such a way as to encourage the generation of false percepts.

Cells pretreated at 38 (2h) exhibited less than 30% normal growth when the 54C stress came immediately after the 38C treatment. Tolerance to the 54C stress develo

Abstract:

Marine bioinvasion has been increasing exponentially due to intensive human activities. To manage the threats posed by marine bioinvasion, it is important to understand the key factors for invasion success. Stress tolerance is thought to play an important role in the invasion process, however, little is known of the nature of this tolerance, particularly whether stress tolerance is species- or population-specific. To determine this, laboratory experiments were conducted to investigate differential tolerance of populations of a cosmopolitan marine invasive mussel, Perna viridis, and whether str

Abstract:

Stress has been found to both facilitate and impair memory depending on the memory phase during which the stressor occurs. Generally, stress has been shown to facilitate memory consolidation and impair retrieval. Research has revealed conflicting findings regarding the effect of stress on encoding. While some studies have demonstrated an impairing effect, others have found a facilitatory effect of stress on memory performance. To explain these findings, researchers have suggested a time-dependent effect of stress on memory. Stress is proposed to facilitate memory for temporally proximate event
