Temperature Changes

The changes in dynamic properties such as natural frequencies and mode shapes are used in vibration health monitoring as tools for assessing the structures health status. They are, however, also affected by environmental conditions like wind, humidity and temperature changes. Of particular importance is the change of the environmental temperature, and it is the most commonly considered environmental variable that influences the vibration health monitoring algorithms. This paper discusses how cable-strut structures can be designed such that their first natural frequency is less sensitive to the temperature changes. The optimization problem is solved by using a genetic algorithm. The level of pre-stress can be regulated to achieve the solution, particularly when a symmetric self-stress vector is chosen.

Physiological Assessment

The kinetic response of bacterial growth to an inhibitor concentration and/or environmental temperature changes was investigated. Microorganisms have a physiological state which adapts to a given environment, and they need a process to transfer to a new physiological state when the environmental condition changes. As an index of the physiological state, the cellular mass at the time of the initiation of the deoxyribonucleic acid (DNA) replication was chosen. From this viewpoint, a simple relation between the unbalanced growth behavior and the physiological state is proposed as being able to describe unbalanced growth under inhibitory and temperature changes. Applying this relation and using ethanol as an inhibitor, the calculated values of unbalanced growth after changes of ethanol concentration and/or temperature could simulate the experimental data with high accuracy. This method might also be applicable for forecasting profiles of unbalanced growth in environmental water or wastewater, which contains complex or unknown materials.

Different Levels

1. It is confirmed that TSH has a more marked effect on the teleost thyroid at high temperatures. 2. The secretion of TSH is increased at high temperatures. 3. The temperature to which the animal is subjected prior to the experiment has no long-term effect on thyroid activity. 4. The thyroid-pituitary relationship is affected by temperature changes, and it is suggested that the TH:TSH ratio may be set at different levels by altering the environmental temperature.

Choice Feeding

The choice-feeding method has been suggested as an effective way of estimating nutritional requirements and it may be helpful from a practical point of view for meeting the nutrient requirements of animals with great variability in nutrient intake and requirements, for example sows in lactation. Friend (1971) reported high variability in protein intake in lactating sows on choice feeding. Growing rats (Leshner et al.,1971) respond to temperature changes by modifying the proportion of protein selected in order to maintain their protein intake. The main objective of this experiment was to investigate the ability of sows offered diets of different nutrient content to select the combination that best fits their requirement, particularly in relation to problems of reduced food intake routinely encountered in high summer temperatures.
