886 Uppsatser om Pressure release - Sida 3 av 60

Föredra att förebygga - En litteraturstudie om sjuksköterskans preventiva insatser mot trycksår.

Pressure ulcers cause a lot of patients unnecessary suffering. This suffering could be decreased through improved knowledge about prevention, so that pressure ulcer will not appear. The purpose with this review was to study how nurses assess risk and prevent pressure ulcer, and to study how nurses use available knowledge. The method consisted of searches in databases and searching trough references. Our result is based on ten articles, qualitative, quantitative and reviews.

Fotens plantara tryck med hellånga variserande och valgiserande inläggskilar

AbstractIntroductionWedged shoe insoles are used as a treatment for different problems in order to change the ground reaction force. They can secondary cause different loading patterns under the foot compared to normal. No previous study has, to the author?s knowledge, clinically evaluated the plantar foot pressure with different full-length wedges in normal persons.PurposeThe purpose was to evaluate the plantar pressure with different degrees of full-length wedges in normal persons.MethodTwenty persons with normal feet have participated in this single blind study. Wedges were produced clinically in four different shapes, 3° valgus, 0° flat, 3° varus och 6° varus.

Matarverk för Camcoil

By our employer Camatec Industriteknik AB have we been given the assignment to continue with the previous work ?Design of strip feeder?. Our goal with this work is to come up with a design basis for a strip feeder.Functionally a strip feeder consists of two rollers which with the aid of the friction between the strip and the coating on the roller create a strip force that pulls the strip through the working progress.Demands on this project:? 10 ? 600 mm in strip width and 0,1-1 mm in strip thickness.? Minimum 30m/min in production speed.? A maximum strip force on 30-40 kN.? The cost of the strip feeder?s components is to be considered of economy and quality.The need of a strip feeder occurs when the coil doesn?t manage to feed or pull the strip before or after a working process. The strip can otherwise be exposed by a permanent yield deformation or a change in the strip material if it?s pulled trough the working process only by the on ? and of-coils.

Bättre åtkomst till avverkningstrakter med anpassat marktryck från avverkningsmaskinerna

The global climate-change means increasing mean-temperature and higher precipitation in Sweden, which leads to shorter periods of frozen ground in the forest. At the same time the harvesting machines are getting bigger and more powerful. The forest industry aim at an even wood flow, and the ground damage has to be as low as possible. The two biggest causes for ground-damage is the bearing capacity of the forest ground and the ground-pressure of the harvesting machines. The aim of this study was to find out some rules for the machine choice considering ground pressure, when harvesting on ground with low bearing capacity.A field study, using a Valmet 890.3 forwarder, was carried out where different ground pressures and their effect on the ground were tested on two different types of ground.Additionally, an inventory of damaged harvesting grounds was made.

Att leva med kroniskt obstruktiv lungsjukdom : En litteraturöversikt över patienters upplevelser

Background: A health damage that has been specifically related to nursing is pressure ulcers. Pressure ulcers are a complication caused by disease, care and treatment and can result in great suffering for the patient. Pressure ulcers can affect people both physically and psychosocially and is experienced, by most patients, as a serious and unnecessary complication of care. Today there are hundreds of identified risk factors for pressure ulcers described that can be divided into patient and care-related risk factors. A successful pressure ulcer prevention and treatment is to reduce or eliminate the underlying causes for the development of pressure ulcers, prevent deterioration and to treat existing ulcers.

Ena dagen student nästa dag nyutexaminerad sjuksköterska

Background: Every year about 4600 nurses are examined in Sweden. The work as a nurse is responsible and she is often working under time pressure. Aim: To describe nurse?s understandings about her professional role during her first year after the examination. Method: Systematic literature review, where 10 scientific articles were examined.

Lakningsförsök med furubarksflis : en utredning om utsläpp av fenolföreningar samt metallsorption

The filters used today to purify water are often expensive and the need to find new filter materials is substantial. Studies of pine bark have shown that this is a material that may be used as an alternative to conventional filter materials, such as activated carbon. However, the study of pine bark has shown that a leakage of phenolic compounds may occur when using the material for water purification. Therefore, the purpose of this report is to investigate the release of phenols from pine bark, in order to evaluate the use of pine bark as a filter material. Another assignment is to investigate the amount of metals adsorbed by the filter material.

Kronisk mitralisinsufficiens hos hund : samband mellan graden av klaffinsufficiens och det arteriella blodtrycket

Myxomatous mitral valve disease is a common disease in older dogs of small- to medium-size breeds. The mitral valve, and less commonly the tricuspid valve may be affected which causes them to leak blood from the ventricle to the atrium of the heart during systole. With increasing severity of mitral valve leakage the forward stroke volume ejected into the aorta decreases, which may lead to an increase in blood pressure in the pulmonary vein resulting in pulmonary edema. A decrease in cardiac output may lead to a decrease in blood pressure, but the body may respond in order to normalize the blood pressure. Franzén showed in 2007 that the systolic blood pressure was increased in dogs with severe mitral insufficiency.

Ångsterilisering av morötter. Infekterade med Lactobacillus plantarum.

The purpose of the project was to exam steams ability to sterilize carrots infected withLactobacillus plantarum. The project was a cowork with Brämhults Juice AB. They hadobserved an increase of Lactobacillus in the production of carrot juice during the summer. Tokeep the flavour of fresh fruits, the juice is treated carefully with heat. This means that thejuice only stays fresh for a few days, around two weeks for an unopened package and threedays for an opened package.In an attempt to remove the remaining Lactobacillus of the carrots, steam is tested as an extrastep in the production of juice.

Kan intag av mejeriprodukter med låg fetthalt sänka blodtrycket?

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Does low fat dairy products reduce blood pressure?Author: Emma Bergman and Naman LimaniSupervisor: Lena HulthénExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 26, 2014Background: It is estimated that at least a third of the population in Sweden have a high blood pressure with genetics, unhealthy diet and physical inactivity as the main contributing causes. High blood pressure is one of the greatest risk factors to develop cardiovascular diseases, which is the leading cause of death worldwide. Milk is a nutritional food product and previous research suggests that low fat dairy products may have blood pressure lowering effect.Objective: The aim was to examine the scientific basis of how low fat dairy products affect blood pressure.Search strategy: Twelve searches were conducted on PubMed and Scopus, where the chosen search terms were combined to produce a broad search as possible in the particular area. The search terms used were dairy, dairy products, milk, blood pressure and hypertension.Selection criteria: Studies on normotensive or hypertensive individuals who received low fat dairy products were included.

Sahlgrenska Academy at University of Gothenburg Department of Internal Medicine and Clinical NutritionAbstractTitle: Alpha-linolenic acid from flaxseed oil and effects on blood pressure ? A systematic reviewAuthor: Christine Hårdfelt och Liduina van SitterenSupervisor: Helen LindqvistExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: April 9th, 2014Background: High blood pressure is strongly associated with an increased risk of developing cardiovascular disease, particularly stroke. ALA-fatty acids have previously been associated with decreased blood pressure. Flaxseed oil is very rich in these fatty acids and has also been highlighted as an affordable and sustainable source.Objective: To investigate whether ALA-fatty acids from flaxseed oil may affect blood pressure in people with high risk for cardiovascular disease.Search strategy: Two searches in PubMed and Scopus were performed. The sample was specified by using specific keywords.Selection criteria: The criteria for inclusion of studies required that flaxseed oil was compared with a control and that blood pressure was measured as an endpoint.

Fysiska strukturer i Umeälvens gamla älvfåra och dess inverkan på laxsmoltens utvandringsframgång

The survival of hatchery reared smolts is generally low after release. To get a better understanding of what variables affecting migration success, Atlantic salmon smolts were studied during their out-migration in the old river channel in the lower part of river Umeälven. The area consists of shifting habitat and complex structures which causes difficulties for smolt on their migration out to sea. The aim of this study was to try to determine the effects of feed restriction, fin conditions and different physical barriers in the river, on the migratory behavior of Atlantic salmon smolts in the river Umeälven. The river was divided into six different sections using acoustic receivers strategically deployed along the river. Two-year old hatchery-reared smolts (n=150), in three different weight classes, were tagged with acoustic transmitters.

Analys av klimatskärmens lufttäthet i ett småhus

Together with NCC and Sweco we measured the air-flow on a semi-detached house in Jönköping. When a pressure measurement is made, the house gets exposed to over- and under pressure. This is done in order to examine the houses climate shell. The climate shell of the semi-detached house we tested exceeded the required air thickness in BBR-2002, hence, measures have to be taken.This report also displays the importance of building air thick houses and what consequences a non air-thick house can have for the ones residing the house. A discussion of different measures is on for the addressed problems with the flow-measurement and the alternative construction-solutions.Furthermore we have described in this report of how to account for the performance of the air pressure, what kind of equipment we used and how we came up with the results.

Direktiv 2001/18/EG om avsiktlig utsättning av GMO och dess inverkan på svensk rätt : en europarättslig studie om svensk institutionell och processuell autonomi samt principen om god förvaltning

This master's thesis on the subject of public law will deal with the implications ?Directive 2001/18/EC on the deliberate release into the environment of genetically modified organisms? might have on the Swedish legal system. The purpose of the directive is to harmonize the European Union States legislation regarding licensing of the deliberate release of GMO?s into the environ­ment, this to maintain a high level of environmental protection and at the same time preserve the internal market of the European Union. The thesis will primarily examine how the provisions of the directive relating to the general principle of good administration have impacted the proce­dural autonomy of Sweden.

Tryckpulsgenerering för funktionskalibrering av mätsystem

The running of gas turbines with low emissions causes high pressure pulsations to arise in the combustion chamber. These pulsations are high amplitude sound vibrations. At some frequencies these are harmful to the gas turbine. Hence these pulsations are monitored to avoid operating conditions where pulsations are specifically harmful. It is necessary to expose the system of known pulsations to verify the functionality of the monitoring process.
