Interventioner som reducerar oro inför och under anestesi hos vuxna patienter

BackgroundResearch shows that the majority of patients feel anxiety before and during anesthesia. It has been shown in several studies that preoperative anxiety may cause adverse effects in the postoperative course. Nurse anesthetists have a key role in creating a safe environment and the opportunity to use different interventions to reduce the degree of anxiety.AimThe aim of the study was to examine which interventions may reduce anxiety in adult patients before and during both general, local and regional anesthesia.DesignSystematic literature review with a quantitative approach.ResultsSeveral studies indicate that gabapentin and pregabalin can reduce anxiety before and during anesthesia. The anxiety reducing effect appeared to be dose dependent. The naturopathic drugs Citrus aurantium blossom and Passiflora incarnata Linneaus were found to reduce anxiety before anesthesia.

Optimering av driftläggningar i Fortums nät

Future emission legislation puts great emphasis on increasing the efficiency of the engine, thereby reducing fuel consumption. The tribological contact between cylinder liner and piston ring is where an great amount of energy is lost due to friction, and by reducing these losses an Reduction in fuel consumption can be achieved.The aim of this thesis was to evaluate the tested piston ring coatings against a plasma sprayed cylinder liner and rank these combinations of materials for friction and wear resistance. The coatings that were tested was Cr + Al2O3, (Al,Cr)N, two types of CrN and WC / C.The experimental tests were performed with a so-called pin-plate, where used oil with addition of an acidic mixture of sulfuric and nitric acid to mimic the acidic condensate formed when exhausts recirculate, were added with a continuous flow. The results were then analyzed by weighing, studies by optical microscopy and scanning electron microscopy (SEM) and profile measurements.The results from each material combination were that the plasma coated cylinder liner wears too aggressively in order to yield a ranking of the piston ring coatings based on the parameters of friction and wear resistance. It is therefore proposed that an alternative coating on the cylinder liner should be developed, lacking the large abrasive wear on piston rings and that can withstand the corrosive environment resulting in engines equipped with EGR.

Vägen till sprututbytet : Studie av brukarinflytande vid implementeringen av sprututbytet i Stockholm län

Studien undersöker förekomsten av brukarinflytande vid implementeringen av det första sprututbytet i Stockholms län. I studien ges en bakgrund till Sveriges narkotikapolitik och hur dess utvecklingen har sett ut från 70- talet fram till idag. I bakgrunden till studien presenteras ett governace-perspektiv på brukarinflytande och de deliberativa processer där brukarinflytande är en naturlig del av policyprocessen.Syftet med studien är undersöka förekomsten av brukarinflytande i implementeringsdelen av den besluts- policyprocess som ledde fram till sprututbytets öppnande i april 2013.Studiens teoretisk ramverk består av teorier som ifrågasätter givenheten i governance-synsättet på brukarinflytande genom hänvisning till svårigheter med aktörskap och risken med konstruerat brukarinflytande.Forskningsstrategin som studien utgår ifrån är intervjuer med utvalda respondenter som har varit delaktiga vid implementeringen av sprututbytet samt brukarorganisationer som representerar och företräder sprututbytets målgrupp.Resultatet av studien visar på en svag förekomst av brukarinflytande vid implementeringen av sprututbytet. Det brukarinflytande som kan anses har förekommit har varit på en individuell nivå och icke-formaliserat.I analysen presenteras tre möjlig förklaringar till den svaga förekomsten av brukarinflytande vid implementeringen av sprututbytet samt en analys om svårigheter med aktörskap vid implementeringen kopplat till studiens teoretiska ramverk..

Moss-sedumtakets bullerdämpande egenskaper : The noise reduction capability of greenroofs

Syftet med arbetet är att få en förståelse för moss-sedumtakets bullerdämpande egenskaper. Jag kommer även att försöka förutsäga med hjälp av akustikteori vilken utav de två olika uppbyggnadssystemen av moss-sedumtak som ger den bästa bullerdämpande effekten.Mätningarna kommer att bestå i att registrera ljudtrycksnivån i rummet, vid varje oktavband i frekvensområdet 125-4000 Hz. Först utan moss-sedummattan och sedan med moss-sedum mattan. Storleken på differensen i ljudnivån ger en bild av i vilket frekvensområde som ljudabsorptionen är effektivast. För att ytterliggare öka förståelsen för hur moss-sedum absorberar ljud så kommer även absorptionsfaktorn att beräknas.

Effekter av Aggression Replacement Training Program inom Kriminalvården

Huvudsyftet med denna uppsats är att undersöka effekterna av aggressionsersättningsträning (ART) program på tre kriminalvårdsanstalter och två frivårdskontor. Huvudfrågeställningen som belyses i studien är: förändras deltagarna i ART-program med avseende på empati och attityder till kriminalitet? För att besvara dessa frågor har vi utfört för- och eftertester på tre kriminalvårdsanstalter och två frivårdskontor. Instrumenten som användes i testerna är Davis Interpersonal Reactivity Index (IRI) och Mill's Measures of Criminal Attitudes and Associates (MCAA).Slutsatserna som kan dras utifrån denna studie är att den emotionella empati-komponenten "personal distress" visar en minskning som kan förklaras av interaktionen med ART.The aim of this study is to investigate the effects of Aggression Replacement Training (ART) program in some of the prisons and probation authorities of the Swedish correctional system. The specific questions we are trying to answer are: (1) does ART-program change the clients' empathic concern and (2) does ART-program help in changing participants' attitudes towards criminality? This investigation is based on a quantitative inquiry consisting of Interpersonal Reactivity Index (IRI) and Measures of Criminal Attitudes and Associates (MCAA) tests.The overall results of this study indicate that the emotional empathy-component "personal distress" shows a statistically significant Reduction, which can be explained by the interaction with ART..

Avgasrening för framtida miljökrav

SammanfattningI dagens miljöfokuserade samhälle ställs det allt högre krav på den tunga fordonsindustrin varvid den gällande miljölagstiftningen skärpts i flera steg de senaste åren. Scania tillverkar tyngre fordon och motorer som alla måste följa de kommande utsläppskraven. Detta innebär att motorernas utsläpp måste reduceras varför avancerade efterbehandlingssystem har införts i ljuddämparen. En metod för att rena avgaserna från kväveoxider är SCR-teknologi (Selective Catalytic Reduction). Denna teknik bygger på att en urealösning sprutas in i avgasflödet.

Plan för multifunktionella buffertzoner längs Vramsån på Malörten AB: s jordbruksfastigheter

To create multifunctional buffer strips along a watercourse in an economically sustainable way requires consideration of many different factors. In this plan we have selected pollutant Reduction as the main purpose of the buffer strip. We have also strived to achieve minimal income loss due to reduced production, increased biological diversity, good game preservation that leads to higher income from hunting, aesthetical satisfaction and possibility to profit from available subsidies. This is done mainly to make landowners/farmers more interested in creating buffer strips along water courses. As sand is the dominant type of soil in the area, the water course is less affected by surface runoff compared to if the soil would be clay or some other finer texture. Game preservation and subsidies have therefore been the main factors when establishing the width of the strip, because these require wider buffer strips in some cases.

Att tala om ansvar : om Levinas ansvarsbegrepp i gränslandet mellan det etiska Sägandet och det politiskt Sagda

The present essay concerns the Levinasian understanding of responsibility in relation to the two spheres that Levinas introduces in his second major work Otherwise than Being or Beyond Essence, namely the Saying and the Said. The essay investigates some of the different meanings that the concept responsibility takes on in regard to these two spheres, and thus also in regard to the separation between the ethical and the political that is apparent in the book. Is it possible to find a politically uttered responsibility in Levinas Otherwise than Being or Beyond Essence?The essay wants to emphasize the continuous transition between the ethical or the Saying and the political or the Said, and vice versa, with the purpose of showing how the two spheres may be conceived simultaneously. By posing the relationship between the two as a reciprocal rather than a oppositional one, the essay aims to suggest that an understanding of responsibility at once must be ethical and political.

Mindfulness verkan hos personer med kronisk smärta: En systematisk litteraturöversikt

Idag lever cirka 40-65% av Sveriges befolkning med kronisk smärta. Påverkan av kronisk smärta på en persons livsstil varierar, en del ser smärtan som en olägenhet i vardagen medan andra upplever att smärtan påverkar varje aspekt av livet. Det är inte lätt att behandla kronisk smärta då variationer på smärtan är många och diagnosen ofta är osäker. Alternativa metoder för att behandla smärta blir allt vanligare och en sådan metod är mindfulness. Syftet med studien var att beskriva den samlade kunskapen kring mindfulness verkan hos personer med kronisk smärta.

"Sist in - först ut" : Hur turordningsreglerna förhåller sig på den svenska arbetsmarknaden idag?

Abstract The subject of this thesis is the priority rules that apply in connection with mining activity. Already back in the 1800s, there were rules in the so-called Lego Charter concerning protection of workers, mainly servants. When the first modern trade union was founded in the 1870s, also developed a collective agreement. These agreements were the order of priority clauses had to intend to ensure employees' working lives. Exceptions had to be done by ensuring that individual employees' dependents. In 1974 the Act on employment entry and had intended to protect older workers.

Minnesallokering och debugverktyg

The aim of this report is to give a description of a diploma work of 20 points that has been performed during the spring 2006 at Ericsson AB in Borås. The report accounts for the problem and procedure during the diploma work. The software used for this project was embedded in a radio link. The RAM in this radio link was divided into several regions where two were used for memory allocation. The current allocation of memory in the radio link was not optimized with regards to performance, security and memory use and the configuration used made it difficult to determine the memory use of the system and the actual memory need.

HelpSeat

The Smart Grid technology has during the last decade been established as a way to create a greater flexibility on the electricity grid that will be needed as the development moves towards an increased share of renewable primary energy sources in the electricity production. One part of the Smart Grid technology is the ability to shift loads in time, to adapt to either price or emissions, known as Demand Response. This project, which was conducted at KTH in collaboration with the consulting corporation Capgemini, examines the economic, environmental and social aspects of the Demand Response technology. In the project, three household products are used in a model that derives the potential savings in costs and emissions of CO2e. The results show that the actual savings measured in SEK are small, but that the savings measured in percent can be as high as 20 percent. Reduction of CO2e emissions is slightly lower.

Ekonomiskt bist?nd och brottslighet i Sverige

This study examines the connection between Sweden`s crime rate and financial aid, focusing on the effects of social spending on different types of criminal activity in the Swedish municipalities between 2000 and 2022. Using theories such as social support theory and utility maximization, the study investigates the relationship between economic assistance and crimes like theft, attempted murder, drug offenses, and assault. The results suggest a complicated relationship: financial aid is associated with a rise in drug offenses and assaults but a decrease in larceny and robberies, when controlling for all observed and unobserved time invariant factors in the municipal factors (a fixed effects panel data model). However, when we test our model for robustness, the effects disappear meaning that other factors that are time varying in the municipality are biasing our estimates. Examples for this may be factors like peer pressure, substance addiction, and socioeconomic conditions that have a considerable impact on criminal conduct, financial aid alone may not be adequate to curb crime.

Identifiering av slöserier på Lundbergs Plåt AB

Lundbergs Plåt AB is a small company situated in Jönköping. Their main task is to process different kinds of steel such as stainless steel. Lately, they have shown an interest in Lean production.On the basis of the situation mentioned above, we developed the purpose to find and decrease the non value-added wastes in the production at Lundbergs Plåt AB. Out of this, we also developed and answered two questions: Which wastes can be found with help from a value stream mapping (VSM)? In what way can these wastes be reduced and how can these Reductions contribute to an improved production? VSM is the method used to find the non value-added wastes.
