Net Metering - An Essential Part for Achieving Greater Energy Security!

Theoretically, net-metering is the silver bullet created to help a nation to achieve greater energy security. It is possible by the generation at the point of consumption, i.e. distributed generation. It can drive widespread application of DG by incentivizing end-users to take localized power production through non-renewable energy technologies. Despite having beneficial factors, unfortunately, both distribution companies and end-users are reluctant to use net energy meters. What’s Net Metering It is a billing process that allows individuals or businesses are producing own electricity to send unused energy back to the local power grid and get credited back for its retail...

Pheromones & Mating Behavior

Although males’ initial responses to virgin and old mated queens were similar, they attempted to mate with young queens but not old ones (Free, 1971). Differences in the urge to mate could be ac... Although males’ initial responses to virgin and old mated queens were similar, they attempted to mate with young queens but not old ones (Free, 1971). Differences in the urge to mate could be accounted for by differences in the amount and composition of the queens’ sex attractant, or some other odour change associated with age or ovary development. Free (1971) found that the head and thorax...

The analysis of variation in pheromone systems within and between populations of the same species would constitute a considerable contribution to the understanding of the role of pheromones in reproductive isolation. Breeding experiments which test the assortment of different types of pheromones and receptors could be especially useful. The hypothesis presented in this article that differences in pheromone systems of closely related species may result from disruptive selection could be...

There is little evidence for these pheromones. Indeed, under natural conditions the Nasonov pheromone is effective as an attractant in several different behavioural contexts (i.e. when clustering, at the hive entrance, at a source of water) but in each of these situations the nerol and farnesol components appear to have no inuence or are slightly repellent. Frequently two or more pheromones are released during a behavioural situation, sometimes from different castes....

Pheromone olfactory signals are used to delineate the various types of space and are derived from feces, urine and specialized odor-producing skin glands.  Changes in the ability to produce and perceive odors match the animals’ spatial requirements. Although the repelling role of spacing is usually emphasized, its attractive functions are just as important. While it is assumed that odor of occupied space is mainly for communication with conspecics there...

Orientation to a host (or to aggregation pheromones) must inevitably be in opposition to dispersal behavior. The behavioral transition involved has been investigated for aphids (Kennedy and Booth 1963a, b) and can be explained in terms of «hitting stimulus threshold levels (Johnson 1969). At the beginning of the dispersal phase, the insect has a very low threshold for dispersal stimuli, but a very high concentration. The threshold for host-positive stimuli. In...
