Abstract:
Большинство методов оценки обонятельных расстройств имеют широкий спектр применения для диагностики различных заболеваний, в том числе психических расстройств, повреждения головного мозга и нервной системы. Однако , необходимо рассмотреть обонятельную дисфункцию в связи с проблемой блокирования воздушного канала в обонятельной системе человека. Поэтому необходимо разработать узкоспециализированный метод оценки обонятельно-респираторных заболеваний, которые имели бы высокую степень объективности для использования в клинической практике оториноларингологов.

Abstract:
Odour recognition memory was studied in 49 patients with unilateral temporal lobe excision, and 20 control subjects. Odours were presented monorhinally to explore any asymmetry in performance between nostrils, and to test for hemispheric differences between patients with excision from the right versus the left temporal lobe. Testing was by a 2-alternative, forced-choice procedure, immediately after presentation and 24 hours later. A discrimination test was carried out at the conclusion of the memory test, and nondiscriminated odours were excluded from the final memory scores. The contribution

Abstract:
The aroma quality of cigarette smoke is an important characteristic for smokers. It is therefore critical to understand the nature of the key aroma compounds in tobacco smoke and to identify them. Also, knowing how flavour compounds in tobacco smoke are released and how they persist in the nose of smokers would help in designing cigarettes with optimised flavour release for the consumer. One approach is to use Gas Chromatography with Olfactometry detector (GC-0). The GC-Olfactometry technique and the Nasal Impact Frequency (NIF) method were proven to be applicable in analysing the aroma of com

Abstract:
Preventing flavor fade requires an understanding of the relationship between carbonyl amine and lipid oxidation reactions. The polyunsaturated fatty acid content of lipids in peanuts makes them more susceptible to lipid oxidation. The major by-products of the oxidation reaction are nonanal, hexanal, octanal, and decanal. These chemicals are associated with cardboardy, painty, and oxidized flavors associated with flavor fade. The carbonyl-amine reaction yields a variety of pyrazines with positive flavor attributes. Initial flavor notes were explored through sensory work, Gas Chromatograp

Abstract Olfactory tasks are used very often with laboratory animals in studies of the neurobiology of learning and memory. Rats and mice are extremely sensitive in their detection and discrimination of odours, learn olfactory tasks rapidly, and can display higher order cognitive functions in olfactory tasks. This cognitive capacity may rival the ability of primates to learn analogous tasks with visual cues and most likely reflects strong anatomical connections between the olfactory bulbs and higher brain regions such as the piriform cortex, orbitofrontal cortex and hippocampus.

Abstract:
En esta Tesis Doctoral se aplica la cromatografía de gases con detector olfatométrico (la nariz humana) en el análisis de los compuestos volátiles aromáticos de distintos alimentos: el vinagre de vino con Denominación de Origen Protegida “Vinagre de Jerez”, los pistachos tostados y el aceite de oliva. Los distintos métodos de preparación de muestra (la microextracción en fase sólida sobre el espacio de cabeza, o HS-SPME, y la extracción directa con disolvente, o DSE) han proporcionado extractos representativos del aroma de estos productos, y gracias a la técnica olfatométrica empleada (Aroma E

Abstract:
Turkish Air Quality Control Regulation (AQCR) is in force since 1986. However, AQCR does not contain any standards for odour control. In order to respond to various odour complaints and handle odour problems in Turkey, a regulation for odour control is necessary. Since Turkey is a candidate country for European Union, environmental legislation of Turkey has to be improved to the standards of the other member countries. The purpose of this study is to investigate the &ldquo<br>odour problem&rdquo<br>in Turkey, specifically in Ankara, and to establish the odour measurement techniques. The tech

Abstract:
Ce travail de recherche a pour objectif de caractériser le vieillissement aromatique des grands vins blancs et rouges, afin de mieux comprendre l’impact de la perméabilité à l’oxygène des obturateurs (OTR) sur leur évolution. Le premier volet présente l’adaptation d’un protocole de coulométrie permettant de caractériser l’OTR du système d’obturation et son lien avec l’évolution sensorielle et moléculaire d’un vin blanc de Sauvignon conservés 12 ans en bouteille. Ces résultats ont permis de confirmer la forte hétérogénéité des vieux bouchons en liège naturel et plus généralement l’impact de l’o

Abstract:
Le nitrite est un ingrédient essentiel à la fabrication du jambon cuit, pourtant les risques sanitaires dont il est accusé remettent en question son utilisation. L’emploi de cet unique additif permet de remplir de nombreuses fonctions comme la protection antioxydante et antimicrobienne mais aussi le développement de la couleur et de l’arôme. C’est sur cette dernière fonction que ce travail de thèse s’est focalisé avec pour objectif la suppression du nitrite dans la fabrication du jambon cuit.

Abstract:
The natural enemies reported as biocontrol agents of stored products pests have showed promising characteristics to keep the damaging insects under the economic damaging level. Mainly, the studies conducted until now have been focalised on those natural enemies belonging to the families: Pteromalidae, Ichneumonidae, Braconidae and Trichogrammatidae. The biology and the applicative aspects of the parasitoids belonging to the family Bethylidae have been only partially evaluated, thus a lack of knowledge is present.

A implementação de medidas destinadas a minimizar o impacto de odores exige a respectiva avaliação da intensidade, do tom hedónico e da concentração de odor. Para realizar a medida da concentração de odor o método de referência usado baseia-se na Norma Europeia 13725. Este trabalho descreve o conjunto de especificações e procedimentos pr

Abstract:
Leaves and fruit of nine apple (Malus x domestica Borkh.) genotypes were evaluated for insect injury in 1998 and 1999. Foliar and fruit injury from 12 insect species was inconsistently affected by genotype. Spraying trees with oil affected neither fruit insect injury nor fruit phytotoxicity. In choice feeding assays, incidence of Japanese beetle (JB) feeding and leaf area consumed was greater for 'Liberty' than for 'York.' Genotypes did not differ in no-choice feeding assays. Choice and no-choice feeding assays between apple and oak indicated that JB could distinguish host plants in an artif
