Download or read book The Scented Ape written by David Michael Stoddart and published by Cambridge University Press. This book was released on 1990-11-29 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Both men and women devote time and effort to removing natural body odour and replacing it with sexual attractant odours derived from plants and animals - we seem to need to smell of something other than people! Yet of all the apes, we are the most richly endowed with scent producing glands. This book examines the sense of smell in humans, comparing it with the known functions of the same sense in other animals. Odorous cues play a role in sexual physiology and behaviour in animals and there are claims that odour can play the same role in humans. The place of odours and scents in aesthetics and in psychoanalysis serves to illustrate the link between the emotional centres and the brain. The book presents arguments to explain the way in which our ancestral past has given rise to our modern day olfactory enigmas. The material is presented with as much explanation of the technical detail as possible to make the book accessible to a wide readership.

Download or read book Aroma written by Constance Classen and published by Routledge. This book was released on 2002-11-01 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Smell is a social phenomenon, given particular meanings and values by different cultures. Odours form the building blocks of cosmologies, class hierarchies, and political odours. They can enforce social structures or transgress them, unite people or divide them, empower or disempower. The authors argue that the sociology of smell is repressed in the modern West, and its social history ignored. This book breaks the "olfactory silence" of modernity. It offers the first comprehensive exploration of the cultural role of odours in Western history - from antiquity to the present. It also covers a wide variey of non-Western societies. Its topics range from the medieval concept of the "odour of sanctity", to the aromatherapies of South America, and from olfactory stereotypes of gender and ethnicity in the modern West to the role of smell in postmodernity. Its subject matter will fascinate anyone who likes to nose around in the inner workings of culture.

Download or read book Odours in Wastewater Treatment written by Richard M. Stuetz and published by IWA Publishing. This book was released on 2001-03-01 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wastewater treatment works have the potential to generate unpleasant odours, which can results in annoyance and consequently have a detrimental effect on a local population. As a result 'odour control and prevention' has become an important consideration both in the management of existing facilities and in the design and gaining of planning consent for new works. Odours in Wastewater Treatment provides readers with a detailed discussion on the basic principles involved in the formation of volatile compounds in wastewater treatment. Accounts are given of recent developments in the sampling and measurement of odours, practical examples in the prediction and dispersion of odorous emissions are offered and an overview of the technologies currently used to contain and treat odorous compounds presented. Contents Introduction Odours associated with wastewater treatment Odour sampling and measurement Assessment and prediction of nuisance odours Odour control and treatment

Available in PDF, EPUB and Kindle. Book excerpt: If we possessed a true, well established and undoubted theory concerning the function of the nerves in the human body, the principles of smell would be much easier to understand. So far, we do not know for certain whether the action of nerves takes place by means of a subtle fluid, which is instantaneously conveyed from the beginning of the nerves to their ends, or whether, as some think, some sort of vibratory movements is produced in them, or whether the stimulation should be considered as the only sufficient cause, to say nothing of the new opinion concerning the electrical force. Linnaeus Although much has been learned since the time of Linnaeus, it is still true that we do not yet possess "a true, well established and undoubted" theory of olfaction. The literature of the subject, however, has long been rather voluminous - the frequent assertions to the contrary are simply untrue - and is now growing rapidly. Moreover, quite a number of symposia on olfaction (or olfaction and taste) have been held during recent years. For example, in the U. S. A.

Download or read book Words for Odours written by Melissa Barkat-Defradas and published by Cambridge Scholars Publishing. This book was released on 2016-06-22 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: While the human sense of smell has long been considered underdeveloped, there is, nonetheless, a growing body of literature to attest to its remarkable importance in human behaviour. However, there has been very little work conducted in linguistics, which is all the more regrettable as economic globalization has made it increasingly useful to communicate on odours in a variety of domains such as the wine and perfume industries. This volume brings together a number of studies on how olfactory experiences are verbalized, applying both pragmatic and theoretical approaches to better understanding the different strategies speakers use to talk of odours. Four major themes are investigated here. Part I (From Olfactory Perception to Verbalisation) examines the various, complex cognitive operations implemented in the process of olfactory perception. Explorations of recollection processes, also crucial for odour verbalization, provide important insights into how cultural conditions contribute to shaping olfactory memories. Part II (Categories and Hedonic Valence) focuses on how speakers circumvent paucity in vocabulary to describe odours in a variety of ways. Sorting operations make it possible to either select an appropriate linguistic label for a given odour or to compensate for the lack thereof by using consistent descriptions. Indeed, although such cognitive operations are influenced by a subject’s environment, cultural representations and goals, the contributions to this section show that hedonic value is crucial for categorizing odours. Part III (Lexical and Cultural Variation) illustrates that some languages spoken on the African continent (such as the Arabic and Bantu languages) are relatively rich in their olfactory lexicon, thereby revealing the greater attention paid to odours in these societies. That being said, such relative richness or paucity can be modulated through a variety of mechanisms which shape the linguistic output, as exemplified in Part IV (Putting Odours into Words), where the olfactory lexicons of two Indo-European languages (French and Greek) are analysed from a comparative perspective.

Download or read book Sampling for Measurement of Odours written by Peter Gostelow and published by IWA Publishing. This book was released on 2003-05-31 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research into the sampling and measurement of odours has developed in a number of sectors, especially the agriculture, food and process industries, with knowledge from each sector being transferred to the wastewater and solid waste management sectors. Progressive developments in odour research have resulted in researchers re-tracing original research studies to understand the contribution and variability of differing sampling and measurement techniques. There are, however, very few reviews that compile earlier studies across each sector. This study looks at the information used to support current practices in odour sampling and measurement for impact reduction. Sampling for Measurement of Odours reviews European and other internationally available research studies to understand odour sampling and measurement practice in waste applications. The emphasis is placed on appropriate odour sampling and its relationship to differing measurement techniques. As recent developments in standardisation of odour measurement have reduced much of the variation and identified best practice in this area there is, at present, a far greater variation in sampling techniques with serious implications for the quality of samples obtained and their usefulness for assessing odour impact. The review considers the available information on uncontrolled area sources, identifies factors influencing sample losses or transformations and looks at information on the sources of variability identified through standardisation programmes. This need for this report was identified by the Odour Network, an EPSRC-sponsored discussion platform intended to promote multidisciplinary research in the areas of odour measurement, modelling and treatment.

Available in PDF, EPUB and Kindle. Book excerpt: THE SENSE OF SMELL The nose is normally mistakenly assumed to be the organ of smell reception. It is not. The primary function of the nose is to regulate the temperature and humidity of inspired air, thereby protecting the delicate linings of the lungs. This is achieved by the breathed air passing through narrow passageways formed by three nasal turbinates in each nostril. The turbinates are covered by spongy vascular cells which can expand or contract to open or close the nasal pathways. The olfactory receptors, innervated by the 1st cranial nerve, are located at the top of the nose. There are about 50 million smell receptors in the human olfactory epithelia, the total size of which, in humans, is about that of a small postage stamp, with half being at the top of the left and half at the top of the right nostril. The receptive surfaces of olfactory cells are ciliated and extend into a covering layer of mucus. There is a constant turnover of olfactory cells. Their average active life has been estimated to be about 28 days.

Download or read book Neurobiology of Chemical Communication written by Carla Mucignat-Caretta and published by CRC Press. This book was released on 2014-02-14 with total page 614 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intraspecific communication involves the activation of chemoreceptors and subsequent activation of different central areas that coordinate the responses of the entire organism—ranging from behavioral modification to modulation of hormones release. Animals emit intraspecific chemical signals, often referred to as pheromones, to advertise their presence to members of the same species and to regulate interactions aimed at establishing and regulating social and reproductive bonds. In the last two decades, scientists have developed a greater understanding of the neural processing of these chemical signals. Neurobiology of Chemical Communication explores the role of the chemical senses in mediating intraspecific communication. Providing an up-to-date outline of the most recent advances in the field, it presents data from laboratory and wild species, ranging from invertebrates to vertebrates, from insects to humans. The book examines the structure, anatomy, electrophysiology, and molecular biology of pheromones. It discusses how chemical signals work on different mammalian and non-mammalian species and includes chapters on insects, Drosophila, honey bees, amphibians, mice, tigers, and cattle. It also explores the controversial topic of human pheromones. An essential reference for students and researchers in the field of pheromones, this is also an ideal resource for those working on behavioral phenotyping of animal models and persons interested in the biology/ecology of wild and domestic species.

Download or read book Olfactory Cognition written by Gesualdo Zucco and published by John Benjamins Publishing. This book was released on 2012 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was conceived as a tribute to one of the founders of the psychological study of the sense of smell, Professor Trygg Engen. The book is divided into four sections. The first reunites the fields of psychophysics and the perception of environmental odours and discusses the impact of odours on beliefs and expectations. The second addresses cognitive processes in olfaction, how odours are interpreted, lexicalized, associated with contexts and remembered. The third focuses on the cerebral bases of olfactory awareness and the neuropsychological investigation of olfaction with special emphasis on olfactory dysfunctions, and the last concerns affective and developmental processes in olfaction. The aim in producing this book is that it will help promote further research in olfactory cognition and attract new inquisitive scientists to the field. The volume will be a useful resource for academics, students, and professionals who study olfaction, as well as to scientists who work in the domains of perception, cognitive neuroscience and environmental psychology more broadly.
