The pasteurization process for milk and ice cream requires heating the milk to a specified temperature and pressure for a. speeified time to kill all germs and bacteria in the milk. This pressure is constant although the productiem of milk and ice cream goes up and down with consumption and the. seasonal changes. It is the same with the... 

Scientists have been able to compare the seasonal changes in atmospheric carbon dioxide to the seasonal changes in photosynthesis in the Northern Hemisphere. Plants take up more carbon dioxide in...

The load profiles can vary quite considerably, depending on the electrical users. For instance, for a factory the load will depend on the shift operation with a potential low demand at night and at weekends. The load can be influenced by seasonal changes. For instance, it may increase towards winter with greater lighting demands. However, the need for HVAC in computer installation...

Eccentricity variations change the average Earth-sun distance such that annual insolation changes by approximately 0.2%, or 0.5 W/m at the Earth s surface (Crowley and North, 1991). This is small compared to the 10% seasonal changes associated with the other Milankovitch cycles. That a 100 kyr periodicity characterizes both the eccentricity and the glacial-interglacial... 

In order to explain the linkages between strategy and stress response reference will be made to Fig. lb which depicts the patterns of seasonal change in shoot biomass associated with the full spectrum of primary strategies (Fig. la). For simplicity, this diagram refers to the patterns observed in herbaceous plants in a temperate zone situation with a sharply defined growing season. However, the principles adduced can be applied to any life-form or biome. 

Under stable conditions of extremely low productivity imposed by mineral nutrient stress (position 7 in Fig. lb) there is little seasonal change in biomass. Leaves and roots often have a functional life of several years and there is usually an uncoupling of resource capture from growth (Grime, 1977 Chapin, 1980). Because of the slow turnover of plant parts, differentiating cells occupy a small proportion of the biomass and morphogenetic... 

Venom from the globiferous pedicellariae of sea urchins is lethal to mice, rabbits, crabs, lobsters, and worms 70). Seasonal changes in toxicity of such toxins 71) have been observed. The LD q estimate (mice) for toxic fractions from the urchin Tripneustes gratilla ranged from 0.05-0.5 mg/kg 70).
