Queen Victoria was one of the longest rulers in history, and one of the few British women to carry a nation from near revolution to empire in the course of her lifetime. With such an impressive longevity, the Queen saw many events pass by, and experienced many important landmarks in her own life as well. Living through so much rich history, she was one of the most documented monarchs. In this p...

Queenless groups of honey bee workers (Apis mellifera L.) respond with typical increases in their metabolic activity when exposed to queens. Volatile queen odors release 46.8% of the reaction in worker groups compared to combinations of volatile odors and non-volatile factors. Worker groups which were allowed to learn the odor of a given queen were able to discriminate between volatile odors of...

Combinatorial optimization problems form a set of problems which need a considerable effort and time to be solved. Their difficulty lies in the fact that there is no formula for solving them exactly. Every possibility has to be examined in order to find the best solution and the number of possibilities increases exponentially as the size of the problem increases. In this paper we discussed abou...

Identifying species exhibiting variation in social organization is an important step towards explaining the genetic and environmental factors underlying social evolution. In most studied populations of the ant Leptothorax acervorum, reproduction is shared among queens in multiple queen colonies (polygyny). By contrast, reports from other populations, but based on weaker evidence, suggest a sing...

Ropalidia marginata, traditionally regarded as a primitively eusocial wasp species appears to have acquired some features reminiscent of highly eusocial species. Queens are behaviorally passive individuals, yet maintain complete reproductive monopoly and probably use pheromones to achieve this. Regulation of worker foraging is achieved by the workers themselves in a decentralized,self-organized...

Over the centuries till this day, Queen Semiramis is considered one of most renowned female figures Ancient times in cultural memory. Historical sources depict her with both admiration and terrible hate. The problem study lies negative, inaccurate portrayal queen Armenian legends for adult children as well. researchers aimed at studying Legend Ara that adapted by English readers to address inac...

Quantitative analysis of nine major com ponents of the head extracts o f workers and queens of A pis mellifera intermissa was carried out. Queen and worker component patterns were distinct. The patterns of both castes changed with age, and the worker patterns were also affected by being reared in the absence of a queen. The genetic variance o f the com ponent composition o f the extracts was fo...
