Har syrgaskoncentrationen någon inverkan på lungfunktionen vid endotrakeal sugning och lungrekrytering? : En experimentell studie på gris
INTRODUKTIONEn av de mest vanligt förekommande vårdåtgärder som utförs på mekaniskt ventilerade patienterär endotrakeal sugning. För att undvika syrgasbrist i samband med detta, är det vanligt att någraminuter innan sugning öka syrgashalten, preoxygenering. Höga syrgaskoncentrationer kan varaskadligt och bland annat orsaka atelektaser, vilka försämrar gasutbytet i lungan. En fysiologiskreaktion på atelektasbildning är att strypa åt blodförsörjningen till den aktuella lungvävnadenmed förhöjt blodtryck i lungan som följd. Syftet med studien var att undersöka om preoxygeneringsamt lungrekrytering med varierade syrgaskoncentrationer påverkar hemodynamik, lungmekanikoch lungvolymer.METODSex grisar, under anestesi med mekanisk kontrollerad ventilation, preoxygenerades med 100 %eller 60 % O2 under 5 minuter.
Det energisnåla isoleringsmaterialet
This bachelor essay is divided into two parts, the first being a construction of a single-familyhouse and the second an in-depth study of five different isolation materials, analysed from anenergy perspective.The first part, the construction of the single-family house, has been created from knowledgeacquired during three years of studying at KTH Royal institute of Technology in Stockholm, inthe program Architecture and the Built Environment. The constructed house is a one-floorhouse of 137m2with façade plaster, situated in Borlänge, Sweden. The house has a wooden framewhich is built on a on sight cast concrete foundation, on the ground. The house?s roof is a gableroof, which has an angle of 24 degrees.
Anestesi av det neonatala fölet
Every spring you can see newborn foals running on fields among the mare. But some unfortunate end up visiting the equine hospital requiring surgery. This is a challenge for the anesthetist because of the neonatal foal?s unique physiology. Therefore you need to take these differences under consideration when you anesthetize foals.
Energieffektivisering på GETRAG All Wheel Drive AB
En ökad kostnadseffektivitet i svenska företag är viktigt för att dessa ska kunna bibehålla sin internationella konkurrenskraft. Då el- och andra energipriser förutsägs stiga i framtiden ökar även företagens energikostnader. Genom energieffektivisering kan företag minska sina kostnader utan att förlora konkurrenskraft.Detta arbete har utförts på GETRAG All Wheel Drive AB i Köping och syftar till att kartlägga företagets energianvändning och därigenom lokalisera potentiella möjligheter till energieffektivisering av företagets olika processer. Kartläggningen har haft särskilt fokus på elenergianvändningen då denna står för den största kostnaden bland energislagen. Hänsyn har endast tagits till möjliga besparingar och ingen investeringskostnad för effektiviseringsåtgärderna har beräknats.Kartläggningen har genomförts genom mätningar av elanvändningen på produktionsnivå i kronhjulstillverkningen samt insamling av övergripande mätdata över elanvändningen för övriga stöd- och produktionsprocesser.
Planerat kärnbränsleförvar i Forsmark : - med fokus på episyenit
It takes a very long time for ionizing radiation of used nuclear fuel toreturn to a natural background level, for this reason one of the requirements for theselection of the location of a repository was that the environment as well people'shealth would be protected from the harmful effect of radioactivity. This requirementmeans that the waste must be isolated in a geological formation. In Sweden therepository will be built in the crystalline bedrock. The location for the Swedish nuclearfuel repository at nearly 500 meters depth at Forsmark in Östhammar was decided 3June 2009. The repository will be located at Söderviken, close to the Forsmarknuclear power plant in a 1.90 billion year old bedrock that will accommodate 12,000tons of spent nuclear fuel.
Bakom Ladan : En skiss eller två på en hälsoträdgård på Wij Trädgårdar
AbstractThe research in the interdisciplinary field of natural-human-health-design has in recent decades gainedmomentum and led to new or new-old ways of thinking and acting in terms of planning and design of outdoorenvironments with the aim of health promotion. Concrete concept models and design guides have begun toemerge as a result of this research.The purpose of this work is to use these guides to develop a design proposal for a supposed health garden,with Wij Trädgårdar in Ockelbo as a base. This has been done in the form of a process description. The targetgroup for the design proposal is long-term unemployed and people who have come to Sweden as refugees.Since the specific design recommendations could not be found for the selected target group, the main materialwas general guidelines for health gardens in combination with guidelines for health gardens directed to targetgroups with stress-related problems, which is a broad target group for which there are relatively much currentresearch.The result is a process description of the progression towards a sketch on a health garden, designed for aspecific spot on Wij Trädgårdar, but available for use in other locations, provided adjustments is made to thespecific location. The sketch is supplemented with plant suggestions to different parts of the garden.

The theoretical framework this essay work form, is Peter.

The purpose of the study was to describe hemodialysis patients self-reporting salt habits associated with cooking and food intake. Furthermore, the purpose was to investigate possible differences in inter Dialyze significant weight gain at low and high self-reported salt consumption. The study was an empirical descriptive study of comparative features and consisted of a convenience sample from two hemodialysis units in southern Norrland. Study group consisted of 37 persons who had been ongoing hemodialysis treatment and their age ranged from 42-86 years. A questionnaire was used in two parts and both parts contained 15 foods.

AimThe aim of this study is to examine students' previous experiences of stay in the nature and their experiences of nature in the context of teaching situations in friluftsliv at GIH. It also aims to elucidate how the teaching of friluftsliv at GIH affects their former interpretation about nature. The questions of the study are: What past experiences of stay in the nature elucidate GIH-students? Have the students approach to nature changed according to the education? If yes ? how? What affects students' perception of nature? MethodTo answer the questions, a quantitative approach (questionnaire survey) and qualitative methods (interview study) was used. The qualitative method is based on phenomenology and hermeneutics.

Handel med utsläppsrätter inom EU - Möjlighet eller papperstiger
This study in Environmental Science examines the amendment of the EU-Directive on. Greenhouse gas emission allowance trading. The Directive is to be considered as a tool for fulfilling the obligations that the Union and its member countries have taken on through the 1997 Kyoto agreement together with the protocols proposed at that time. The flexible mechanisms of the protocol are intended as instruments for limiting the climatic changes arising from anthropogenic sources, emission allowance trading being one of these mechanisms. The results presented here consist primarily of an analysis of interviews with various experts in the field of emission control concerning the possibilities and problems attending the process of implementation.
Urbaniserad hästhållning: stadsnära hästgårdar och planering
As the number of inhabitants increases, the cities expand into the former rural landscape. The urbanization causes changes to the functioning of the peri-urban fringe. Land that previously was used for agricultural production is now used for alternative enterprises, as for example horse keeping and recreation. 75 % of all horses (approx. 200 000) are situated in the peri-urban fringe.
