Pheromone

Non-surgical options include behavioral modification, frequent nail trims, nail caps and feline pheromone sprays. Nail trimming and nail caps do not modify the cat’s behaviour, but it can reduce the damage done from scratching behaviour. Nail caps may need to be replaced every four to six weeks and may require the help from veterinary staff to place the caps. Sedation may be required to place the nail caps. Feline pheromone sprays vary in their effectiveness, as they only reduce stress and…

at puberty, can affect the body in different ways. This pheromone produced during puberty seems to target the hypothalamus in different ways according to the gender of adolescent, affecting how the child acts. The study found that androstadienone affects the hypothalamus of children with and without gender dysphoria. Adolescents with gender dysphoria, born as one gender but behaves as the other, are more strongly affected by this pheromone than a normal heterosexual…

actually the creator of Bat Boy. In part two scene six, Meredith comes forward and tells Dr. Parker and the rest of the town’s people how he was developing a pheromone to increase the birth yield in cattle. The pheromone was designed to stimulate the sexual arousal of the opposite sex in all animal cases, he accidently spilled the pheromone on Meredith causing the stimulation of himself upon her. Meredith was later attacked by bats as she walked home which some sort of consummation had happened.…

2.3.2 PARTICLE SWARM OPTIMIZATION (PSO) Particle Swarm Optimization [27] is a population-based stochastic optimization developed by Dr. Ebehart and Dr. Kennedy in 1995, inspired by social behavior of bird flocking or fish schooling. In PSO, each single solution is a “bird” (particle) in the search space of food (the best solution). All particles have fitness values evaluated by the fitness function (the cost function for ELD problem), and have velocities that direct the “flying” (or evaluation)…

Sexual interactions with same-sex are widespread among animals, but until now the puzzle remains. One of the animals that exhibit this behavior is the Drosophila Melanogaster or fruit flies, in which this paper will be focusing on. Fruit flies have the ability to reproduce rapidly, tendency for males to mate intensely with immature males (Dukas, 2010). Over the past few years, since fruit flies’ genome are simple, researchers made a constant effort in studying the same-sex behavior in Drosophila…

lobster approaches a male's den and giving off wafts pheromone in his direction. Unlike other females, whose pheromone may attract dozens of arbitrary males, the female chooses the male. She usually pursues the bulkiest male in the area and he stands outside his burrow, releasing her scent in a stream of urine from openings just below her antennae. He responds by fanning the water with his swimmerets, permeating his apartment with her pheromone. He emerges from his den with his claws raised…

whereas Katal states, on page 220 of the text under “Individual Differences,” that women before puberty and after menopause do not show these gender differences. They both go on to talk about humans increased olfactory as a reason behind pheromones. Pheromones are said to explain our ability to “smell…

bloodstream, communicating regulatory messages within the body. One of the basic systems for communication and regulation in an animal body is chemical signaling by hormones which is the function of the endocrine system. The exocrine glands produce pheromones and are secreted into the outside…

The effects of biostimulation originate from bodily responses to pheromones through olfaction, auditory, tactile, and visual stimulation. This is directly associated with the fact that pheromones interact with the hypothalamus to generate pulses of gonadotropin-releasing hormone. However, it is not clear how these cues are transmitted from male to female (Rekwot et al., 2001). Prepubertal…

feeders, others attack only particular types of plant. The flea beetle has a narrow host range to plants primarily in the brassicaceae. Most of the flea beetles prefer cruciferous plants which produce allyl isothiocyanate, known as aggregation pheromone of the cabbage flea beetle. The most-preferred hosts are in the genus Brassica (Cruciferae), which include the major agricultural host attacked by flea beetle, oil rapeseed and mustard. Beetles emerge…
