Omvårdnad av självmordsnära patienter inom psykiatrin - En kvalitativ intervjuundersökning utifrån ett sjuksköterskeperspektiv
Suicide and attempted suicide frequently occur in society today and represent a major public health problem. In inpatient psychiatric care the nurse have a central role when caring for suicidal patients. Few systematic studies exists that address the nurse?s practical work with these patients. The purpose of this study was therefore to describe the nursing care of suicidal patients as it was perceived by registered clinical expert nurses.
Intern kontroll : Inom mindre grossistföretag
Accounting is a well discussed topic, and an important tool that allows stakeholders and others to interact with the companies. To gain credible reports, the companies require maintenance, activities and monitoring. Wholesalers account for approximately 20% of Sweden's net and is increasing at a steady pace. Few studies on wholesalers are acquired and the internal control has shown to be important for the preparation of the financial statements.Therefore the study will be focusing on the smaller wholesaler?s internal control, all the way to the financial statements.
Strukturell konservering av måleri på duk Studie kring den långsiktiga stabiliteten hos Plextol D 360, Plexisol P550 och Beva 371
In the early 80s, several new synthetic materials have come to be used in the treatment of canvaspaintings, among them Plextol D 360, Plexisol P 550 and Beva 371. Today, many conservatorsfind the information about the long term sustainability of these binding mediums to beincomplete. Evaluation of synthetic materials is mostly done through clinical research, sometimesartificial aging is simulated. The correlation between artificial and natural aging is however notestablished, useful information can therefore be gained through evaluations of actualconservation treatments. The intention of this study is to find out more about how thementioned products perform over time in normal museum conditions.
När gränsen för styrning suddas ut - En fallstudie av hur ett företags styrning påverkar dess kundrelationer
As collaboration between companies move beyond the single transaction into more long-term relationships the consequences of a company's control system become more complex. The aim of this paper is to provide an understanding of how intra- and inter-organizational control and work practices interact through examining how a company's intra-organizational control influences its customer relationships. The empirical research is performed through a qualitative case study where interviews have been conducted with management and sales staff within the case company as well as with one of the customers. The empirical findings have been analyzed using frameworks and theories regarding management control and customer relationships. The study reveals that the intra-organizational control of the case company affects its relationships with customers in a number of ways.
Åtgärder för biologisk mångfald i parker : Fallstudier i Botkyrka, Haninge och Nynäshamn
Biodiversity consists of all life on Earth and in all forms. Biodiversity is often discussed at three levels: ecosystem, species and genetic variation within species. Biodiversity also provides many of the ecosystem services performed by nature and that we depend on, including cultural services such as aesthetic values, education and recreation. In Sweden the environmental objectives are central; there are 16 environmental quality objectives, and "A rich plant and animal life" is one of them. Conservation and sustainable use of biological diversity is a prerequisite for achieving also most other environmental objectives. Another environmental quality objective that is tied to a rich biodiversity in cities and biodiversity is "Good built environment" where cities, towns and other built environment should provide a good living habitat and contribute to a good environment.
Automatisering av spraytorkningsprocess
ABB Surge Arrestors in Ludvika have for a long time had a problem to keep the moisture at a steady state in the production of their ZnO-powder, that is used to produce varistors.Some black-box models of the spray drying process have been designed and evaluated to find a solution for the problem. After evaluating the collected data it has been found that variations in the supply voltage causes control difficulties for the operator. A cascade control system was designed, consisting of three PI control loops designed with lambda tuning. The disturbance in the supply voltagewas used as a feed forward in the control system.At the end of the project the control system was installed, and tests were made to verify the functionality of the regulator. It was shown that most of the variations in the moisture of the powder could be eliminated using small resources, through purchase of a process controller and four power meters.
En j?mf?rande studie mellan tv? v?treng?ringsmetoder p? papper
Amongst the published literature researching wet cleaning of paper there is a limited amount of
studies conducted researching the method simmering water treatment. There are even less studies
conducted on how simmering water affects the paper being treated when used as a cleaning method.
Despite the limited research, there are literary reviews describing the method and suggesting it as an
alternative for conservation of paper with iron-gall ink. The following study will therefore be
examining, the somewhat unusual method, simmering water treatment, and comparing it to one of
the more common wet cleaning methods: immersion washing. This is done to compare how the
different temperatures of the water affect the paper.
The types of paper used in this study consists of three dyed and four undyed papers. All of the papers
are new, apart from one sample originating from 1847.
Locus of Controls inverkan på strategier för konflikthantering i kärleksrelationer
Syftet var att undersöka om personers Locus of Control påverkar deras konflikthanteringsstrategier i kärleksrelationer. Hypoteserna var: H1: Det finns skillnader mellan personer med extern och intern Locus of Control när det gäller vilka typer av strategier de använder för att hantera kärleksrelationsproblem. H2: Personer med intern Locus of Control har större benägenhet att använda sig av relationskonflikthanteringsstrategin Kompromiss i sina kärleksrelationer. H3: Kvinnor påverkas mer än män av Locus of Control när det gäller vilka typer av strategier de använder för att hantera kärleksrelationsproblem. Deltagarna var 172 studenter.
Styrreglage för hållbarhetsstyrning - En fallstudie av hur företags interna styrning aktiverar Levers of Control för att uppfylla hållbarhetskrav
The connection between management control systems for controlling sustainability and a firm's motivation for engaging in sustainability is not completely understood (Arjaliès & Mundy, 2013). The aim of this thesis is to develop a more profound understanding for management control in achieving sustainable companies. To do this, we raise the question: How and to what extent do companies use management control systems to achieve sustainability compliance Simons's Levers of Control (1995) are applied to this question in order to get a consistent and thorough insight of management control systems. Hence, a case study of ABB:s work to achieve material compliance in accordance with EU-regulation was conducted. The findings of the case study reveal that ABB uses the regulations as explicit goals and implement them in sustainability procedures.
Mekaniserad plantering med Eco-Planter i södra Sverige :
This report is a thesis work for a B.Sc. in Forestry exam at the School for Forest Engineers, SLU. The work was an assignment from Södra Skogsägarna and the aim of the work was to investigate the economical and biological output after mechanical planting with Eco-Planter compared with traditional manual planting.
Eco-Planter is a tool for mechanized planting, fixed at the end of the boom on a conventional harvester.
The study confirms that manual planting is less expensive under normal conditions. However, the differences between mechanized and manual planting are not that big and with technical development and/or increased labor costs together with an improved work organization the system with Eco-Planter could be competitive.
The biological output, e.g. planting result and survival rate, seems to be quite good.
Triac Driver Platform
In the electronic industrials, power control of AC motors is commonly used. For example power control of a washing machine motor, a vacuum cleaner motor or a coffee machine motor. The company Rejlers Ingenjörer AB has many projects where power control of AC motors is included. A prototype card for this task can save time and money for the company in the future and this is the reason for this thesis.The motors are power controlled by a TRIAC and control of the trigging pulses to the TRIAC. This card is modularly built and can easily be adapted for future projects where the power control of AC motors are included.The prototype card can be used as a subsystem in a larger electronics projects or as it is in lab environment for testing and evaluating new motors..

To be allowed to sell Z-suspended vehicles with dipped beam Xenon or LED lighting, Scania have to develop automatic headlight level control. This master?s thesis aims to be the foundation to that development.The thesis consists of several parts; a market analysis of how competitors to Scania and the general vehicle industry solve this problem; several available principles for detecting the amount of control needed; the construction of a test station for sensors, a control unit and components connected controlled by the control unit; a further theoretical and practical development of one principle ? one rotational sensor connected between the chassis and the back drive axis; a state flow model programmed in Simulink that produces the control signal for the headlight leveling from the sensor input.Lastly the thesis gives some recommendations to the further development and implementation of automatic headlight level control on Scania vehicles..
Validering av den svenska översättningen av Impaired control scale ? självskattningsskala som undersöker kontroll av alkoholkonsumtion
Föreliggande studies syfte var att undersöka validitet och intern konsistens för den svenska översättningen av Impaired control scale (ICS), en självskattningsskala som mäter grad av kontroll av alkoholkonsumtion. ICS består av subskalorna; Attempt control (AC), Failed control (FC) samt Predicted control (PC). Svar på ICS sammanställdes från respondenter (n = 203) som behandlats för alkoholproblem vid mottagningar i Västra Götaland. Faktoranalysen visade en bakomliggande faktor för AC, och två faktorer för FC respektive PC. Den interna konsistensen var god.
