Linho (Linum usitatissimum L.) em meia malha de máquina circular para usuário com dermatite atópica em clima subtropical / Linen (Linum usitatissimum L.) in single jersey of circular knitting machine for wearer with atopic dermatitis in subtropical climate

José Aparecido Favilla 01 December 2014 (has links)
O objetivo deste trabalho e o desenvolvimento de roupas utilizando malha de linho para uso como primeira camada em contato direto com o corpo em usuários com dermatite atópica. Roupas disponíveis para essas pessoas com pele sensível, incluindo algumas com algodão, muitas vezes provocam irritação na pele e uma malha de linho pode ser uma boa opção de uso, com base em suas reconhecidas propriedades de contato saudável ao corpo humano, principalmente em climas quentes. Protótipos de malhas consideradas pelo autor como clássicas ou oclusivas e outras como não oclusivas foram produzidas com algodão, fibras descontinuas de poliéster e linho em estrutura jérsei de malharia circular. As malhas foram confeccionadas em roupas para um teste de uso experimental em 4 crianças entre 5-8 anos de idade, sendo 2 delas saudáveis e duas com dermatite atópica, previamente avaliadas por um dermatologista. O resultado final demonstrou um bom grau de tolerância por todos os usuários quanto ao uso da malha com linho em contato direto com a pele. As malhas não oclusivas foram as que apresentaram os melhores índice de permeabilidade ao ar,atributo que pode evitar o bloqueio da transpiração insensível durante rotinas diárias, minimizando o abafamento, desconforto térmico e potencial gatilho de irritação da pele. Câmera infravermelha foi utilizada como uma ferramenta adicional na Avaliação térmica durante o uso. Os resultados sugerem que a malha com linho não oclusiva e uma opção viavel de uso pelos portadores de dermatite atópica em clima subtropical como o da cidade de São Paulo. O controle da estabilidade dimensional da malha com linho e amaciantes naturais amigáveis a pele para a lavagem domestica das roupas são desafios que devem ser equacionados em futuros desenvolvimentos / Linen (Linum usitatissimum L.) in single jersey of circular knitting machine for wearer with atopic dermatitis in subtropical climate The purpose of this work is the development of first layer linen knitted structure aiming wearers with Atopic Dermatitis (AD). Available clothing for these sensitive skin people, including some cotton garments, very often presents skin irritation and linen is an option based upon it recognized friendly contact to human body and comfortable wear during hot climates. Classic or occlusive and non-occlusive garments prototypes knitted in single jersey of circular knitting machines with cotton, polyester staple and linen fibers were designed to accomplish an experimental wear test with 4 children with 5-8 years old, 2 with AD and 2 health kids. Voluntaries showed good wear tolerance to knitted linen that presented highest air permeability index that can help to avoid blocking of insensible perspiration during daily routine, minimizing buffering effect and potential trigger of skin irritation. Infrared camera was used as an additional tool for thermal evaluation during use. Results suggest that non-occlusive knitted linen is a possible option for AD wears at subtropical climate like the city of Sao Paulo. Dimensional stability control of nonhocclusive knitted linen and natural home laundry softeners are challenges to be overcome in future developments

Perspiratio- en del i vätskebalansen? : Enkätundersökning på Sveriges intensivvårdsavdelningar för vuxna / Perspiratio - A part of the fluid balance? : A survey on intensive care units for adults in sweden

Wallander, Marcus, Hellström, Kristina January 2013 (has links)
Bakgrund: I intensivvårdssjuksköterskans arbetsuppgifter ingår att räkna och registrera vätskebalans. Normal perspiratio är mellan 800-1100ml/dygn. Vätskeförlust via perspiratio är svårberäknad och hos den kritiskt sjuka patienten är de individuella skillnaderna ännu större och perspiratio kan bli större än normalt. Syfte: Att undersöka om perspiratio räknas in i vätskebalansen samt vilka faktorer som påverkar beräkningen. Metod: En empirisk, deskriptiv och analytisk studie med kvantitativ ansats. Datainsamlingen skedde genom frågeformulär utdelade till vårdenhetschefer på intensivvårdsavdelningar i Sverige. Resultat: Studien visar att på intensivvårdsavdelningarna var det vanligast att vätskeförlust via perspiratio räknas in i vätskebalansen. På dessa intensivvårdsavdelningar fanns skillnader i vilka faktorer som påverkade beräkningen. Vanligast förekommande var att beräkningen påverkades av patientens temp, andningsfrekvens och kroppsvikt. Slutsats: Att räkna med perspiratio som en del i vätskebalansen förefaller allmänt förekomma på intensivvårdsavdelningar i Sverige. Alla intensivvårdsavdelningar har inte riktlinjer för hur vätskebalans skall räknas. Det finns skillnader i vilka faktorer som påverkar beräkningen av perspiratio och detta stödjer det faktum att perspiratio är svårt att beräkna. Det finns även ett starkt samband mellan att ha riktlinjer och att räkna perspiratio. Klinisk betydelse: Det kan finnas ett intresse för intensivvårdssjuksköterskor att ta del av hur andra intensivvårdsavdelningar förhåller sig till perspiratio i vätskebalansen. / Background: In the intensive care nurse's duties measuring and register fluid balance is included. Normal perspiration is between 800-1100ml/24h. Fluid loss through perspiration is difficult to quantify and in the critically ill patient the individual differences are large and perspiration can exceed the normal amount. Purpose: To investigate if perspiration is accounted for in the fluid balance and which factors affects the estimate. Method: An empirical, descriptive and analytical study with quantitative approach. Data collection was done through questionnaires distributed to heads of wards in intensive care units in Sweden Results: The survey showed that most intensive care units included fluid loss through perspiration in the fluid balance. In these intensive care units there were differences in which factors that affect the calculation. Most common was that the calculation was influenced by the patient's temperature, respiration rate and weight. Conclusion: Register perspiration as part of the fluid balance seems generally to occur in intensive care units in Sweden. Not all intensive care units have guidelines how to measure fluid balance. There are differences in the factors that affect the calculation of perspiratio and this supports the fact that perspiratio is difficult to calculate. There is also a strong correlation between having guidelines and counting. Clinical significance: There may be an interest for intensive care nurses to learn about how other intensive care units relate to perspiration in the fluid balance.

Hulter, Birgitta January 1999 (has links)
<p>The purpose of this investigation was to study sexual function in women with neurological disorders at fairly distinct and separate locations. The dissertation comprises descriptive, retrospective, quantitative studies on sexual functioning in women with hypothalamo-pituitary disorders (HPD) (<i>n</i>:48), multiple sclerosis (MS)(<i>n</i>:47), and insulin-dependent diabetes mellitus (IDDM) (<i>n</i>:42). The results werecompared with those in an age-matched control group (C) (<i>n</i>:42), and as reported by representative Swedish women (<i>n</i>:742) in the Swedish sex survey SiS). The studies were based on comprehensive interviews, neurological examinations, incl. Vibration Perception Thresholds (IDDM), concentrations of prolactin and testosterone in serum (HPD), and a checklist on life satisfaction (IDDM, C, and SiS).</p><p>Sexual dysfunction was prevalent in almost all women with HPD and MS, and in 40% of the IDDM group. The problem of insufficient vaginal lubrication was more common in those with neurological disorders than among women in the SiS group. Sexual problems caused by reduced libido and orgasmic difficulties were more commonin the HPD and MS groups than in the SiS group. In the HPD group, women with intrasellar adenomas had better sexual function than women having expansively growing pituitary adenomas with both intra- and suprasellar extension. Normal serum testosterone values correlated to masturbation activity. Amenorrhea and older age werecorrelated with sexual problems in all groups. In the MS group, symptoms of a weak pelvic floor and of bladder and bowel dysfunction were correlated with reduced lubrication and orgasmic ability. In the IDDM group, signs of autonomic neuropathy were correlated with sexual dysfunction. Concerning life satisfaction generally,proportionately fewer women with IDDM were satisfied or very satisfied, though differing significantly from the other two groups in only two domains of life: contacts with friends, and physical health.</p>

The effect of textiles on perceived physiological comfort while backpacking in the cold

Rau, Lynn M. 04 June 2012 (has links)
Clothing is the primary means that wilderness backpackers have to protect themselves from injuries and illnesses that can occur while hiking in the cold. The current method of layering clothing may not meet backpackers' needs for both thermal insulation and heat dissipation, particularly in areas of the body that produce greater sweat, and during times of high physical exertion. No previous studies have addressed backpackers' needs for thermal and moisture comfort in different body areas within a single layer garment. The purpose of this study was to design and evaluate a single-layer garment of different textiles, to improve the physiological comfort of male backpackers hiking in cold winter weather conditions. The objectives of this study were to identify the physiological comfort needs of male backpackers hiking in the cold, to design a prototype backpacking shirt to improve comfort, and to evaluate the comfort and performance of the prototype over time, in comparison to a control. Male backpackers were recruited from a wilderness therapy company in Bend, Oregon, where subjects' employment duties included regularly backpacking in the cold. Qualitative data was collected by interviewing the subjects about their physiological comfort needs, types of garments and materials worn, dissatisfactions and preferences with hiking clothing, and locations on the body that need better attention to thermal and moisture comfort. Information provided by the qualitative interviews was used to develop design criteria. From the guarded hot plate and moisture management testing, results were used to select one thermal insulation, moisture management, and control fabric for the garment design. Based on the design criteria, a prototype shirt was developed. A prototype garment was constructed using the combination of the thermal, moisture, and control fabrics; while a control garment was constructed in an identical style using only the control fabric. The prototype and control garments were worn and tested by subjects while they backpacked. Additionally, comparisons of thermal insulation data between the prototype and control garment were collected on a thermal manikin. Major findings from the qualitative interviews were that subjects preferred base layer shirts made with synthetic fibers and style features that helped retain body heat. Subjects preferred to have greater thermal insulation in the chest and the arms, and less thermal insulation in the underarms and upper back area. Additionally, subjects were concerned about durability. A polyester fleece pile-knit was selected for the thermal insulation fabric and located in the arms and chest of the prototype. The moisture management fabric selected was a polyester fiber mesh knit fabric and was located in the upper back, underarms, and side seams of the garment. The control fabric was a brushed polyester double knit fabric and was located in all other body areas of the prototype and in the entire control garment. The wear test data indicated that both the control and prototype garments were perceived to be comfortable. The prototype had slightly better overall comfort than the control, and there were significant differences found between the prototype and the control in the areas of overall comfort, combined thermal comfort, and combined moisture comfort. The prototype did not consistently have better comfort performance than the control in each trial and for each subject. It was found that the prototype and control shirts could be worn without additional layers when the temperatures were above 35 ��F and 40 ��F, respectively. Thermal manikin testing results confirmed that the overall thermal insulation of both test shirts was equal, but that the prototype had greater or less thermal insulation than the control in specific body areas, depending on the placement of the thermal insulation or moisture management fabric. In summary, the prototype shirt designed in this study has accomplished the goal of providing backpackers' physiological comfort needs identified in the qualitative interviews.�� The design prototype, when worn alone, is able to keep backpackers comfortable when hiking in cold conditions, particularly in temperatures above 35��F. Although not intended to be worn as part of a layer system, the prototype also keeps backpackers comfortable when they are wearing multiple clothing layers. The use of different fabrics in different body areas satisfies the backpackers' needs of both retaining and dissipating body heat with changes in physical activity. Although both the prototype and the control shirts were found to have good thermal, moisture, and overall comfort, the prototype had slightly higher overall comfort ratings than the control.�� In addition, both the prototype and the control were perceived to be better than the subjects' own base layer shirts, and all subjects were willing to recommend the shirts to other hikers. / Graduation date: 2013

Rozpoznávání živosti otisků prstů / Fingerprint Liveness Recognition

Lodrová, Dana January 2007 (has links)
This document deals with presentation of nowadays software and hardware methods used for fingerprint recognition with focus on liveness testing and thereafter it deals with description of my solution. In order to describe results obtained from study of technical literature, we discuss important terminology of biometric systems at first and further main principles of fingerprint sensors used in practice are shown. From overviewed methods of liveness detection we underline one method based on  perspiration (researched by BioSAL laboratory) and one spectroscopic method researched by Lumidigm Corporation. The study of liveness testing methods inspired me to creation of new type fingerprint sensor which has built-in livennes testing method based on two characteristic properties of living human tisue. In order to test this sensor, we discuss nowadays sensor deception method. It follows from their analysis, that newly designed sensor should be theoretically resistant to each of them.

Etude de la production et de l'émanation de composés volatils malodorants sur textile à usage sportif / Production and emission of human body odors from textile for sports

Léal, Françoise 04 November 2011 (has links)
Si la sueur fraîchement émise par le corps humain est inodore, la dégradation de celle-ci par la flore bactérienne cutanée produit des composés volatils malodorants, responsables des odeurs de transpiration. Les odeurs de transpiration apparaissent également sur les vêtements au cours de leur utilisation, particulièrement sur les textiles réalisés en fibres synthétiques. Ce travail a pour but d’améliorer la compréhension du phénomène d’émanation d’odeurs en étudiant l’effet du sujet testé, l’effet de la flore bactérienne et l’effet du textile sur les émissions de composés volatils malodorants.L’intérêt de ce travail réside dans l’approche globale de la problématique des odeurs de transpiration et dans la diversité des méthodes de mesure mises en place, tant dans l’étude de la flore microbiologique que dans les méthodes de mesures des composés odorants émis.Dans un premier temps, le dénombrement simultané de la flore bactérienne sur la peau et sur le vêtement a été réalisé sur un échantillon de 15 sujets à l’issue d’un exercice physique. Cette expérimentation a permis d’évaluer le taux de transfert bactérien moyen lors d’une activité sportive et d’étudier son rôle dans l’émission d’odeurs. Ensuite, afin d’affiner ces résultats, une méthode basée sur la biologie moléculaire a été mise en place pour réaliser le suivi qualitatif de la stabilité de la flore commensale axillaire d’un sujet pendant 3 mois. Le transfert bactérien spécifique entre la peau du testeur et le vêtement a été étudié pour 4 matières textiles sélectionnées (dont le coton et le PET). Ceci a permis de déterminer le rôle du transfert bactérien spécifique dans l’émission des odeurs à partir de textile.Enfin, le dernier chapitre est consacré à l’étude de l’émission de composés volatils et odorants à l’aide de mesures olfactives et d’un nez électronique au cours du temps par 8 composants textiles sélectionnés. Après traitement statistique par analyse en composante principale et étude détaillée des mesures, 9 composés chimiques ont été identifiés comme indicateurs d’un comportement textile malodorant. Ces derniers pourraient être utilisés dans la mise en place d’une méthode ciblée de mesure physico-chimique des mauvaises odeurs.Ce travail a permis de déterminer l’impact de chacun des facteurs sujet, flore bactérienne et textile dans l’émission d’odeurs. En outre, ce travail ouvre des perspectives sur l’étude des contaminations bactériennes par contact, mais également dans l’étude des odeurs, sur les phénomènes de désorption de molécules volatiles à partir de différentes matrices textiles et sur les solutions pouvant être envisagées pour limiter les émissions odorantes à partir de textiles. / Fresh human sweat is odorless. Odoriferous volatile compounds are produced by the metabolism of bacteria living on the skin, generating strong malodor. Sweaty body odors do also appear on clothes during use, and especially on synthetic fabrics. The aim of this document is to improve understanding of odor emission by investigating subject effect, microbiota effect and fabric effect on the emission of odoriferous volatile compounds.Odors of perspiration are hereby globally approached with a wide use of methods and experimental devices, for microbial flora study as well as for odoriferous volatile compounds emission study.First, microflora enumeration has been simultaneously processed on the skin and on the fabric after exercise for 15 subjects. This experiment allowed an evaluation of the average bacterial transfer yield during physical activity and the beginning of the investigation of its effect on odor emission.A molecular biology methodology has then been developed in order to refine these results. Monitoring of qualitative composition of the microbiota has been performed to study the stability of the armpit’s ecosystem on a subject during 3 months. Specific microbial transfer from subject’s skin to clothe has been performed for 4 textile fabrics (including cotton and PET). This leaded to characterize the effect of specific bacterial transfer on odor emission from fabric.The last chapter is dedicated to the study of the emission of odoriferous volatile compounds over time using olfactory measurements and electronic nose for 8 selected fabrics. Principal component analysis targeted 9 chemical compounds that have been selected as malodorous behavior indicators for a given fabric. Those 9 compounds could be used for setting up a fitted physicochemical method of malodor.To conclude, this study helped to understand the effect of 3 factors in odor perception from a fabric after sport : subject, microbial flora and fabric. Perspectives have been charted on contact microbial contamination, but also on odor, and especially on desorption of odoriferous volatile molecules from a textile or knitted matrix. The solutions that could be used to limit malodorous emission from fabrics have also been discussed.
