PSVI-33 Queen bees’ artificial breeding using selenium compounds

Breeding Bees to the Crop

Selenium Compounds

Selenium is a naturally occurring substance that is toxic at high concentrations but is also a nutritionally essential element. Hydrogen selenide is the most acutely toxic selenium compound. Acute (short-term) exposure to elemental selenium, hydrogen selenide, and selenium dioxide by inhalation results primarily in respiratory effects, such as irritation of the mucous membranes, pulmonary edema...

Queen pheromone modulates brain dopamine function in worker honey bees.

Honey bee queens produce a sophisticated array of chemical signals (pheromones) that influence both the behavior and physiology of their nest mates. Most striking are the effects of queen mandibular pheromone (QMP), a chemical blend that induces young workers to feed and groom the queen and primes bees to perform colony-related tasks. But how does this pheromone operate at the cellular level? T...

Queen Bees and Domestic Violence: Patrilocal Marriage in Tajikistan

A longstanding tradition of patrilocal marriage – living with the parents-in-law affects every generation of Central Asian women and their choices regarding childbearing, employment and education. While anthropological evidence suggests that elder matriarchs (Queen Bees) play a key and often detrimental role in the lives of the junior women in their households, rigorous empirical studies are sc...

Solving Directional Overcurrent Relay Coordination Problem Using Artificial Bees Colony

This paper presents the implementation of Artificial Bees Colony (ABC) algorithm in solving Directional OverCurrent Relays (DOCRs) coordination problem for near-end faults occurring in fixed network topology. The coordination optimization of DOCRs is formulated as linear programming (LP) problem. The objective function is introduced to minimize the operating time of the associated relay which d...
