Separation av etanol från bakugnsgas

En önskan finns från brödföretaget Polarbröd AB i Älvsbyn att veta om det är tekniskt möjligt och ekonomiskt lönsamt att utvinna etanol ur gasen från bakugnarna. För detta ändamål togs prover på gasen som sedan analyserades med gaskromatografi. Proverna visade att gasen innehöll etanolånga motsvarande en volym av upp till 30 m3 etanol i vätskeform per år. De tekniska och ekonomiska förutsättningarna för att separera ut denna etanol undersöktes och det visade sig vara tekniskt fullt möjligt men ekonomiskt tveksamt att genomföra en sådan separering med konventionella metoder. Nya separationsmetoder under utveckling visade på betydligt bättre ekonomiska förutsättningar.

Ämnen och dominans i ett samtal mellan terapeut och klient : En samtalsanalytisk jämförelse med läkar-patientsamtal

This thesis presents an analysis of a conversation between a therapist and her client. Through a study of the conversation's topics and structure I have been able to draw conclusions on how the therapist governs and steers the session. With the use of certain tools, such as introductions of topics, invitations, paraphrasing and explorative questions, the therapist presents the frames of the conversation. At the same time, though, she invites the client to state her point of view and correct the views imposed on her through, for example, formulations from the therapist. I in my study I have used the methods of Conversational Anlaysis (CA) com-bined with quantitative methods such as calculating the frequency of a phenomenon.Throughout the thesis I have compared my results with the results presented by Ulla Melander Marttala in her dissertation Content and perspective in doctor-patient conversa-tions.

Effektivisering av EPC projekt : Fallstudie Johnson Controls

In todays society the demand on companies to deliver better project management is crucial for them to survive. The higher demands from clients make older project management weak and unreliable. In the constructions sector more and more companies are created and the competition is higher than ever. The clients are aware of the higher competition in the construction sector. This has resulted that construction companies must now make their project management more efficient to create better projects and better relationship with clients. The purpose of this thesis arose from this problem in the construction sector.

Produktivitetsanalys ur ett LEAN-perspektiv : En studie hos OPPC, AstraZeneca

The objective of this thesis is to map the resources and methods used at the department OPPC, at AstraZeneca, and derived from that give suggestions on possible solutions that will increase their productivity.Mapping of the product flow, as well as gathering of process data, has mainly been done using observations, but consultation with the process technicians has also played a great role. Further have theoretical methods been used, based on literature studies, within the areas of Lean production and statistics.The work has incrementally gone forward since the steps taken has been restricted by the irregularity of production which led to the need of creating a fictive production flow. This has affected the lead-time calculations in the way that they are meant to give an indication, rather than an absolute truth, on how different methods described shall be used.The current state analysis showed multiple areas of improvement when defining capacity as value adding time in relation to total throughput time. Using the "standard scenario" as a basis showed that the actual production flow only constituted 50% of the total project time. Further it showed that the workflow contained more non-value adding activities than value adding activities, which is a result of how the work is distributed within the department as well as in the different projects.

Jobbcoachning : En undersökning om hur jobbcoachernas coachningsprocess ser ut

Labour market coaching (Swedish:?Jobbcoachning?) was a comprehensive political project for the Swedish labour market, with the aim of helping unemployed individuals to enter the labour market. Between 2009-2014  the labour market coaching was carried out by private companies through governmental regulations.

Den kommunala folkhälsosamordnaren söker sin arbetsroll

Coordinator of public health has recently become a new profession in the field of Health Promotion. During the last few years the pedagogic perspective has been increasingly important for the coordinators as a way of adapting their work methods to the circumstances. The conditions for coordinators of public health differ between municipalities and thus their tasks and responsibilities may vary with the local structure. According to the literature there are several ways to conduct Health Promotion and it is in the hands of the coordinator to adjust the methods to fit local conditions. The purpose of the study was to examine what influences the coordinators of public health and how that affects their work methods.

Tillförsel av använda fosforfilter påverkar inte tillväxten eller fosforupptaget hos korn

The eutrophication of inshore seas, lakes and watercourses is mainly due to leaching of nitrogen and phosphorus (P) from agriculture. Many efforts are made to reduce the lea-kage of phosphorus in Sweden and the Baltic Sea countries. Phosphorus is also a finite resource and the mining of good quality raw material gets more and more difficult. Se-dimentation dams in combination with filters is one relatively new method to separate P from run-off and drainage water from agricultural land. This study was a part of an IVL Swedish Environmental Research Institute?s project which tests the capacity and func-tion for separation of phosphorus in four phosphorus filters.

Evidensbaserad praktik i socialt arbete

The purpose with this review is to investigate evidence-based practice (EBP), and which arguments are used to justify EBP. The year of 2006 Bergmark and Lundström published an article regarding the problems concerning EBP. They are discussing that several different definitions of EBP are existing, which they mean can lead to difficulties using the EBP-methods in real life. In this study six articles, from the years 2007-2011, have been analyzed using Mertons structure-functional theory and Lipskys theory of street-level bureaucracy. Different definitions of EBP are discussed in the articles and there seem to be a need to clarify the concept.
