To meet the growing amount of waste from electronic and electrical equipment (WEEE) EU developed, year 2002, a directive (2002/96/EG) with the objective to govern the management and reduce the amount of WEEE. The directive is based on producer responsibility which makes the producer responsible for collection and dispose of WEEE. In 2012 a new revised directive (2012/19/EU), with tougher collection targets, was developed. Both the old and the new directive states that the approach to tackle WEEE should be prioritized in order of prevention, reuse and then recycling. Hitherto the amounts of WEEE has increased every year, making it relevant to examine which type of preventive measures the directive contains and how effective they are.

Syftet med denna systematiska litteraturstudie var att belysa hur uppkomsten av trycksår kan förebyggas. Vidare var syftet också att undersöka sjuksköterskors kunskap om trycksårsprevention. Datainsamlingen gjordes via databasen Elin och Chinal där 23 artiklar valdes ut för granskning, Resultatet visade att många som använder sig av riskbedömningsskalor inte riktigt vet hur de ska använda sig av dessa instrument och att de också har en bristande utbildning gällande trycksårsprevention. Studien visade också att många sjuksköterskor litade på sin egen kompetens och det var lika säkert att använda sig av erfarenhet som att använda sig av riskbedömningsinstrument..

Syftet med denna litteraturstudie var att beskriva vilka omvårdnadsåtgärder som kan förebygga uppkomsten av trycksår samt vilken förmåga att identifiera patienter som riskerar att utveckla trycksår sjuksköterskan har med de bedömningsinstrument som finns. De vetenskapliga artiklarna (n = 20) som ingick i studien söktes via Högskolan Dalarnas databaser Blackwell Synergy, PubMed och ELIN@Dalarna. Sökorden som användes i olika kombinationer var pressure sore, pressure ulcers, nursing, routines, treatment, knowledge, methods, management, measures, risk assessment, scales, risk patients och prevention/preventing. Inklusionskriterierna var att de skulle vara empiriska, skrivna på svenska eller engelska samt vara publicerade efter 1997. Resultatet visade att det finns många olika förebyggande åtgärder som vidtas.

Further the aim is to develop a basis to improve the interaction between the fire services and the youth welfare. The conclusions that were made during the project can be used to increase the safety of the environment that estates by the youth welfare..

This master thesis has been a pilot study preceding a forthcoming project of a larger scale with the long term objective to separate the direct effect of added nitrogen on soil processes from indirect effects via trees. The aim of this study has been to investigate the allocation of nitrogen following direct injection of liquid solutions into the xylem of 40 year old Norway spruce. The field site is located at Flakaliden (64°07?N, 19°27?E), approximately 60 km northwest of Umeå, Sweden. A total of 18 trees were selected for treatment, equally divided between three treatments, potassium nitrate, glutamine and water (control).

Introduktion: Att ungdomar medvetet skadar sig själva är ett vanligt problem. Orsaken till detta beteende är lika varierande som motivet för varför man utför dessa handlingar. En del försöker få ut en inre smärta medan andra avser att ta sitt liv. Att hamna i ett självskadebeteende under ungdomsåren kan ge stora hälsoproblem i det vuxna livet och är också en riskfaktor för efterkommande självmordsförsök. Då detta problem är vanligast förekommande bland ungdomar är det också naturligt att skolan har ett viktigt uppdrag då det gäller det förebyggande arbetet mot självskadebeteende.Syfte: Finna stöd för skolsköterskans preventiva arbete då det gäller ungdomar med självskadebeteende.Metod: Systematisk litteraturstudie.

Syfte: Att undersöka om lärare anser sig ha tillräckliga kunskaper för att identifiera och hänvisa vidare elever med psykisk ohälsa, om de anser att tillräckliga resurser finns tillgängliga för att hjälpa dessa elever, samt deras uppfattningar om var det huvudsakliga ansvaret för dessa elever ligger. Metod: Studien var en deskriptiv tvärsnittsstudie och undersökte 32 stycken yrkesverksamma högstadielärare i Dalarnas län. Svaren samlades in via webbenkät. Resultaten bearbetades med hjälp av deskriptiv statistik i statistikprogrammet SPSS (Statistical package for the social sciences). Resultat: Resultatet från studien visade att respondenterna upplever att de inte har tillräckliga kunskaper i hur psykisk ohälsa hos unga kan identifieras samt att de har otillräckliga kunskaper om vilka resurser som finns att tillgå.

Alkoholkonsumtionen i Sverige är idag högre än för 100 år sedan. Många barn växer upp i familjer med vuxna som har en riskfylld eller skadlig alkoholkonsumtion. En hög alkoholkonsumtion hos föräldrarna kan påverka barnen negativt. Det nationella Riskbruksprojektet (2004-2010) var ett regeringsuppdrag med syftet att hälso- och sjukvård skulle arbeta mer aktivt för att minska alkoholkonsumtionen. Sedan 2008 har BVCsjuksköterskor i Stockholm erbjudits utbildningar inom Riskbruksprojektets regi.

Storm water is defined as runoff from precipitation such as rain or snow. It is collected in sewage disposal systems and since it mainly originates from urban areas it can contain high levels of heavy metals, nutrients and oil etc. Polluted storm water is currently treated by different methods such as wet ponds, constructed wetlands and filter strips. This study investigates these methods, which in earlier studies have shown to give varying results regarding their treatment efficiency.This thesis has been written on commission of SWECO VIAK and was aimed at studying those parameters that may affect the treatment efficiency of nutrients and heavy metals in storm water treatment facilities (STF:s). Through literature studies the dominating treatment processes in ponds and wetlands were examined.

This master thesis was a continuation of a previous study in the diesel exhaust characterization, which is part of the academical work embedded in the EMIR-1 project. The main objective of this thesis work was to finish the installation and make the proper modifications of the particulate mass measuring system located in one of the engine test cells at KTH, in order to be able to measure the mass of the particles from the exhaust of diesel engines.This experiment requires a diluted flow sample from the exhaust that should be sent to the device that makes possible the measurement of particle mass, called TEOM. In the first stage of this project, the objective was to study and make the proper modifications in the existing KTH diluter because there were several problems to obtain a constant dilution ratio from it during tests.This modifications were made and it resulted in a great improvement in the maximum inlet and outlet flow that this diluter can handle. Therefore another modification is proposed for controlling the inlet exhaust flow so it will be possible to regulate the dilution ratio and make it constant along a wide range of engine loads and speeds.The second and most important stage was to make particulate mass measurements possible by analyzing the frequency signal from the TEOM device. The idea was to obtain the frequency of oscillation from the tapered element in the TEOM, and therefore with the proper correlations, be able to predict the particulate mass concentration in the exhaust flow from the engine.An electrical problem in the TEOM circuit was detected and corrected, so the signal that carries the frequency from the TEOM can be analyzed properly.

Eight healthy 3-day-old foals were given repeated injections of trimethoprim-sulfadiazine intravenously for 3 days, at a dosage of 15 mg/kg bodyweight (2,5 mg trimethoprim and 12,5 mg sulfadiazine). Blood samples were collected prior to each administration and for the following 24 hours after last administration. Serum concentrations of trimethoprim and sulfadiazine were measured and the pharmacokinetics for the substances were studied. The elimination half time (t½) and clearance (ClB) for trimethoprim and sulfadiazine for the foals did not diverge from adult horses. According to these data it is possible to assume that the same dose interval and dose can be used for foals as for adult horses.

Poly- and perfluoroalkyl substances (PFASs) are a group of environmental contaminants that have gained increasing attention due to their potential to bioaccumulate, environmental persistence and potential toxicity. PFASs have been found in surface water, sediment, air, soil, sludge and ice caps globally, as well as in wildlife and humans. Furthermore, PFASs have also been detected in drinking water, leading to raised concerns for human health, since drinking water is one of the most significant sources of PFASs for the general population. Conventional water treatment techniques have shown to be ineffective removing PFASs, highlighting the importance for further research to develop efficient removal techniques. The aim of this study was to investigate the removal efficiency of PFASs in water using two treatment techniques; granular activated carbon (GAC), type Filtrasorb 400®, and anion exchange (AE), type Purolite A-600. Additionally, the effect of dissolved organic carbon (DOC) on removal efficiency was studied.

The aim of this essay is to see if there are any relationship between the four Megalithic graves, and the newly excavated dwelling site in Resmo socken on Öland. The Megalithic graves on Öland consist of one dolmen and three passage graves. Is the excavated site a settlement? Since there are no signs of housing constructions, I will also explore other possible purposes of the site. What surprised the excavators was the concentration of pits that contained ceramics, flints and burned bones.

Fetma ökar alltmer över hela världen och i dess fotspår följer sjukdomar som diabetes, hypertoni, artros och sömnapné. Den vanligaste orsaken till fetma, är att vi lever ett mer stillasittande liv än tidigare och att vår kost blir alltmer energirik. När det gäller barn och ungdomar ses ännu större sjukdomsrisker, om man redan som ung är överviktig. Lek som innefattar någon form av fysisk aktivitet tenderar att minska bland barn i alla åldersgrupper. Fetma är en sjukdom medan övervikt inte är det, men vid övervikt är risken större att utveckla fetma.
