Shape theory of olfaction: The Shape theory of smell proposes that a molecule's smell character is due to its molecular shape, molecular size and functional groups. It has also been described by a 'lock and key' mechanism by which a scent molecule fits into olfactory receptors in the nasal epithelium.Piriform cortex: In anatomy of animals, the piriform cortex, or pyriform cortex, is a region in the brain, part of the rhinencephalon situated in the telencephalon. The function of the piriform cortex relates to olfaction.Olfactory receptor: Olfactory receptors expressed in the cell membranes of olfactory receptor neurons are responsible for the detection of odor molecules. Activated olfactory receptors are the initial player in a signal transduction cascade which ultimately produces a nerve impulse which is transmitted to the brain.Olfactory ensheathing glia: Olfactory ensheathing glia (OEG), also known as olfactory ensheathing cells (OECs) or olfactory ensheathing glial cells, are a type of macroglia (radial glia) found in the nervous system. They are also known as olfactory Schwann cells because they ensheath the non-myelinated axons of olfactory neurons in a similar way to which Schwann cells ensheath non-myelinated peripheral neurons.Odorant-binding protein: Odorant-binding proteins are abundant small soluble proteins secreted in the nasal mucus of many animal species and in the sensillar lymph of chemosensory sensilla of insects.Olfactory sulcus: The medial orbital gyrus presents a well-marked antero-posterior sulcus, the olfactory sulcus, for the olfactory tract.MapracoratCitronellalAmmonia volatilization from urea: Urea (46-0-0) accounts for more than fifty percent of the world’s nitrogenous fertilizers.Schwab, G.Percolation threshold: Percolation threshold is a mathematical concept related to percolation theory, which is the formation of long-range connectivity in random systems. Below the threshold a giant connected component does not exist; while above it, there exists a giant component of the order of system size.Perfume: Perfume ( ; ) is a mixture of fragrant essential oils or aroma compounds, fixatives and solvents used to give the human body, animals, food, objects, and living spaces "a pleasant scent."Sustentacular cellStatistical relational learning: Statistical relational learning (SRL) is a subdiscipline of artificial intelligence and machine learning that is concerned with domain models that exhibit both uncertainty (which can be dealt with using statistical methods) and complex, relational structure. Typically, the knowledge representation formalisms developed in SRL use (a subset of) first-order logic to describe relational properties of a domain in a general manner (universal quantification) and draw upon probabilistic graphical models (such as Bayesian networks or Markov networks) to model the uncertainty; some also build upon the methods of inductive logic programming.Kenyon cell: In arthropods' nervous system, Kenyon cells are mushroom body neurons derived from globuli cells. Some species possess hundreds of thousands of Kenyon cells.Manure management: Manure management refers to capture, storage, treatment, and utilization of animal manures in an environmentally sustainable manner. It can be retained in various holding facilities.To Kau Wan: To Kau Wan () is a bay on the north shore of northeast Lantau Island, Hong Kong. Contaminated soil from Penny's Bay was transferred here for thermal desorption to separate the Volatile Organic Compounds (VOC) and Semi-Volatile Organic Compounds (SVOC) along with cement immobilization of metal contamination from Penny's Bay.Trail pheromone: Trail pheromones are semiochemicals secreted from the body of an individual to impact the behavior of another individual receiving it. Trail pheromones often serve as a multi purpose chemical secretion in which, it leads members of its own species towards a food source, while representing a territorial mark in the form of an allomone to organisms outside of their species.List of diseases of the honey bee: Diseases of the honey bee or abnormal hive conditions include:Druglikeness: Druglikeness is a qualitative concept used in drug design for how "druglike" a substance is with respect to factors like bioavailability. It is estimated from the molecular structure before the substance is even synthesized and tested.Sensitization: Sensitization is a non-associative learning process in which repeated administrations of a stimulus results in the progressive amplification of a response. Sensitization often is characterized by an enhancement of response to a whole class of stimuli in addition to the one that is repeated.Sexual motivation and hormones: Sexual motivation is influenced by hormones such as testosterone, estrogen, progesterone, oxytocin, and vasopressin. In most mammalian species, sex hormones control the ability to engage in sexual behaviours.Avoidance reactionConditioned place preference: Conditioned place preference (CPP) is a form of Pavlovian conditioning used to measure the motivational effects of objects or experiences. This paradigm can also be used to measure conditioned place aversion with an identical procedure involving aversive stimuli instead.
