Denitrifikationsmöjligheter hos lakvattnet på Bredemads avfallsdeponi i Ljungby
I examensarbetet har möjlig denitrifikationshastighet för lakvattnet på Bredemads avfallsdeponi i Ljungby undersökts. Denitrifikationshastigheten har tagits fram i satsvisa och kontinuerliga försök där Reppos 40T och Brenntaplus VP1 har jämförts som externa kolkällor. De satsvisa försöken har genomförts i temperaturerna 15 °C, 20 °C och 22,5 °C och de kontinuerliga försöken har genomförts med reningsmetoden ?Moving Bed Biofilm Reactor? (MBBR) med bärare som hade en skyddad yta på 500 m2/m3.Denitrifikationshastigheten i g/(dygn?m2) med Reppos 40T var 0,45 och med Brenntaplus VP1 1,05. I reaktorn med Reppos 40T var fyllnadsgraden 48 % och denitrifikationshastigheten 4,5 g/(h?m3).
Signalförändring i automatisk urinmätare : - en ingående studie om dess orsaker
Denna rapport diskuterar vilka ämnen i urinen som påverkar förutsättningarna för utvecklingen av biofilm i Observe Medicals automatiska urinmätare Sippi och på så sätt stör mätsignalen. Idéer och förslag på åtgärder mot detta problem diskuteras. Rapporten tar upp fem olika lösningar som har testats med produkten: albumin utspätt med vatten, fritt hemoglobin utspätt med vatten, albumin blandat med urin, fritt hemoglobin blandat med urin samt endast urin. Volymmätningarna gick till på ett sådant sätt att varje lösning pumpades från en behållare till mätkammaren i Sippins engångsset. Alla mätningar utfördes med två varianter av engångsset.

Utvärdering av den biologiska reningen av processavloppsvattnet vid GE Healthcare i Uppsala
GE Healthcare operates in Uppsala (Sweden) and develops systems, equipments and medium to purify medical substances. Discussions with the local authority concerning planed far-reaching changes and upgrades of the biological process techniques for sewage management, aroused the question about revising the terms of permit for the activity. Therefore it seemed necessary to evaluate a newly installed biological process technique, which is the background of this thesis. The evaluated biological treatment process was built in 2003 and consists of a biological reactor filled with moving bed carriers with a high surface area for biological growth. At the time of the project the biological wastewater treatment plant consisted of a flow equalization facility and two following parallel biological processes; a biological reactor with moving bed carriers and a tower trickling filter.The aim of this thesis was to survey the function of the biological reactor with respect to the reduction of organic matter.
Jämförande LCA av engångssängkläder och tvättbara sängkläder i sjukvården
Inom sjukvården används ? precis som överallt där människor sover ? sängkläder av hygienskäl. Problem med smittspridningar av typen multiresistenta bakterier (MRSA) och spridning av andra sjukdomar har drivit företag som Cellcomb i Karlstad AB till att utveckla engångssängkläder för att förhindra detta. Engångssängkläderna är skyddade av en biofilm som ska ge ökat skydd mot bakterier och fungerar som en barriär så att inte vätska tränger igenom. Problemet är att det inte finns mycket till underlag för hur engångssängkläderna står sig mot vanliga sängkläder ur miljösynpunkt.
Älgarås avloppsreningsverk- studie och metodisk felsökning av en biobädds BOD-rening
Wastewater contains biodegradable materials, which are often measured as BOD7.Trickling filters are sometimes used as a purification step for BOD-reduction. Atrickling filter is a tower, which is filled with a carrier material. Microorganisms growon the carrier material in the form of a biofilm. This biofilm consists mostly of bacteriathat purify water from BOD.In Älgarås? wastewater treatment plant the water is purified by a trickling filter.However the treatment plant has difficulties reaching the emission requirements forBOD.
Kärnprocessen inom barnhälsovården
The core process is responsible for internal business development and is the process that runs through the organization and the results which creates a value for the customer. Some research suggests that identification of the client's conscious or unconscious needs clarifying the so-called core process in the organization and operations can thus be more effective. The study aims to identify and analyze the experience of the core process within child health care. The method has been interviews with nine managers and 10 clinic nurses in a county. The results show a lack of knowledge regarding core process and process work.

Investeringsbedömningsprocessen för strategiska investeringar - en fallstudie av NordiCorp
The aim of this study is to examine the investment decision process for investments that arise due to strategic changes and are of strategic importance to the company. At the foundation of this study is the previous research in this area, done by King (1975) and Bower (1970), which examines the investment process on a more generic level. At the core is the investment decision process pertaining to Projekt X, an investment performed by NordiCorp. Having conducted a case study including six interviews with employees from various parts of the organization, combined with a large number of internal documents, the process regarding the investment decision was carefully illuminated. The results show that in many regards, this process follows the more generic investment process.
ERP-implementation och processkartläggning : En studie om implementering av ett ERP-syste, och vilka fördelar en processkartläggning kan ge för kravställandet.
To implement an ERP-system is not an easy process. The success of the implementation depend on many different variables. The most important one is perhaps the requirement process, to define what the organization wants and expects from the system. In this study, the advantages of a process mapping are examined, in relation to the phase where the requirements are expressed in an ERP-implementation. The conclusion is that a process mapping generates an increased communication with the supplier of the ERP-system, hence the business knows their processes and thereby what they want from the system.
Från plats till resmål : Etableringsprocessen
In this thesis we have examined why the establishment process of travel destination is essential for the tour operators and how the process can be influenced by different conditions. The thesis is written from the perspective of the tour operators and with the tour operator Ving as our case study, we have been able to create a picture of how the establishment process of travel destination may look like.We have chosen to deal with some different areas in this thesis that all are important for the creation of a holistic picture of the process. The overall segments listed in this thesis are the process itself, the tourist, marketing, the product creation and demand. By connecting our theoretical framework to the collected empirical data from our case study, we have analyzed the establishment process and drawn our conclusions..
Effektivisering av kravspecifikationsprocessen
The goal of this project was to make the requirement process at the Swedish Coastguard more effective. The first step to achieve this was done by locating bottle necks in the process with value stream mapping method. The result of this study showed that the biggest restriction in the requirement process was while examining older requirement documents to understand what elements were suitable for the particular project. This was followed by a study of literature, interviews and theory of Lean Production with the ambition to investigate how the requirement process was handled on other companies and how to improve the process on the Swedish coast guard. This led to a number of potential enhancements of the process which later was evaluated.
Nätverkandets påverkan på organisationssammansättningen
Networking is an important part, for organizations, in the recruitment process. This since the emergence of Internet networking has become more common and the organizations finds that networking is applied more frequently in the recruitment process. Organizations have noticed that networking often is a more cost efficient option compared to traditional recruitment. Since networking in the recruitment process has increased, we intend to investigate if and how it affects the composition of organizations. This thesis aims to examine networking in the recruiting process, and aims to make no differences between networking offline and online.

Requirements written by different people in different organizations were
analyzed in order to sort out if there were some similarities? which could be
used as standard elements in a future standardization of the process.
Vem sa att det ska vara fint? : En studie om tre bildlärares syn på process och produkt i bildundervisningen
Denna studie behandlar begreppen process och produkt. Syftet är att genom ett hermeneutiskt perspektiv undersöka några bildlärares syn på begreppen process och produkt i bildundervisningen på högstadiet. Tidigare har fokus legat på elevers färdiga produkt men idag är bedömningen i bildämnet mer fokuserad på elevers process (Skolverket, 2012:3). Undersökningen genomfördes genom kavlitativa intervjuer. Intervjufrågorna är förankrade i Lindströms (2002:4-5) process- och produktkriterier.
