Kartläggning av upphandlingsprocessen inom vatten- och avloppsbranschen ? användning av livscykelkostnader i processen
Syftet med offentlig upphandling är att konkurrensutsätta marknader och skapa bästa möjligaaffär för de offentliga medel som den upphandlande myndigheten har till sitt förfogande.Offentlig upphandling ska ske med långsiktigt perspektiv och det finns verktyg för att tillse attett långsiktigt synsätt erhålls. Ett av dessa verktyg är livscykelkostnader (LCC) som beaktaren produkts anskaffning, ägande och avveckling. En produkt som har ett högtanskaffningsvärde men låga framtida kostnader, kan bli det mest kostnadseffektiva inköpet.LCC används för att göra en ekonomisk värdering av olika investeringsalternativ,diskonterade över produktens livslängd. Livscykelkostnader är ett synsätt som utforskar deolika investeringsalternativen och används aktivt för att föra en dialog mellan aktörerna iupphandlingsprocessen.Användningen av livscykelkostnader, kan antas vara till god hjälp för beslutsfattarna i vattenoch avloppsbranschen (VA) om de vill ta långsiktigt korrekta beslut. Problematiken är attingen har kartlagt hur ett livscykelkostnadsverktyg påverkar beslutsprocessen i offentligaupphandlingar inom VA-branschen och om det ger beställaren ett tydligt beslutsstöd.
Rackmonterad elektrolyscell
This report shows methods and workflow when exploring the potential to change Outotecs HCD Silver Electrolysis machine to a module type. It?s done as an attempt to lower the workshop and installation costs and to give customer a more accurate prize directly. To do this a concept was produced which was set to a stress test. Additional objectives were to investigate freight and installation procedures, pneumatic connections and to calculate the difference in cost.Once the concept, a reinforced type of the original frame, was chosen stress tests in computer simulations were made and appropriate alterations were made.
Några elevers känslor och tankar i ett möte med en skalbagges livscykelstadier / A couple of pupils? emotions and thoughts when meeting a beetle?s life cycle stages.
Avsikten med detta arbete är att undersöka vilka känslor och tankar elever kan ha till djur, samt om de kan ändras när eleverna blir bekanta med djuren. Vi har valt att utföra en kvalitativ undersökning där vi kombinerar metoderna intervju och observation. Undersökningen genomfördes på tio elever i årskurs ett, där alla enskilt fick bekanta sig med en skalbagges alla livcykelstadier under ca 10 minuter. I början och slutet av varje intervju bad vi eleverna att berätta vad de kände och tänkte när de såg djuren, därefter grundade vi vår analys och tolkning av vårt material med hjälp av konstruktivismen.
I vår undersökning såg vi att alla elever hade någon sorts känsla för och tanke om djuren, dock kunde det vara svårt att tyda känslorna eftersom vissa elever verbalt kunde uttrycka en känsla medan kroppsspråket visade en annan.
Belastningsskador vid montering : Påverkan på svensk tillverkningsindustri och hur effektivt förebyggande kan bedrivas
AbstractAccording to research made by Statistics Sweden on the members of the labor union IF Metall the number of reported musculoskeletal disorders for employees working under the collective bargaining agreement for the automotive industry has almost doubled since 2003. During 2004- 2006 and 2008 male assembly workers were the occupational group with the highest amount of reported work related disorders in Sweden. To prevent musculoskeletal disorders is according to Rose and Orrenius important both for the individual, the society and the industry by reducing economic and personal costs. The purpose of this paper is to identify and analyze how the manufacturing industry is affected by musculoskeletal disorders that occur when working with line assembly and how companies can prevent them. The report aims to provide the reader with an understanding of what musculoskeletal disorders are, to which extent they occur in assembly, how companies are directed by laws and regulations and how they affect the Swedish manufacturing industry and their employees.

Thymidinkinas 1 som tumörmarkör vid juvertumörer hos tik :
Determination of serum thymidine kinase 1 (TK-1) activity is used as a tumour
marker in both human and veterinary medicine. TK-1 is an intracellular enzyme
involved in a salvage pathway of DNA synthesis. The expression of TK-1 is cell
cycle dependent and the activity increases markedly after the G1 to S transition in
the cell cycle and then declines rapidly in G2. The pronounced proliferative
activity in tumour cells result in a higher TK-1 enzyme activity within the cell.
The fact that the increased TK-1 activity can be measured in serum makes TK-1 a
useful marker in diagnostics of neoplastic diseases and it provides information
regarding prognosis and treatment effectiveness. In human medicine a radioactive
based test is used to determine the TK-1 serum activity.

VARDAGSLIV MED CANCER
The health care system in most western countries is undergoing rapid changes with an increasing amount of people living with chronic cancer. These people have to deal with their disease in every day life together with working and family life. The relationship between health services and every day life has changed and raises new requirements.
Earlier research has shown that maintaining every day life is important for cancer patients and their families. This study comprised patients with lymphoma receiving their diagnosis during 2003 ? 2005.

The work that is the basis of this Master Thesis was performed on Scania´s group of cabdevelopment, and concerns the GPS-system in Scania´s trucks. Today, the GPS-systemconsists of an active antenna mounted on the roof of the truck. The antenna is connectedto the receiver with a coaxial cable.The purpose with this Master Thesis was to develop and evaluate a new GPS-system,where the information is distributed using a LIN-network. Today, each unit requiringGPS-information is equipped with its own antenna and receiver. This solution has beenthe most cost effective to this point.
ESC-analys och studering av knack på en "Diesel Dual Fuel"-motor
A one-cylinder research engine has been used for studies with a Diesel Dual Fuel concept (DDF). DDF is a concept that utilizes a pilot diesel injection to ignite a homogenous natural gas/air mixture. Emissions and engine efficiency have been analyzed in an emission cycle called European Stationary Cycle (ESC) and the knock/pre-ignition problems with this type of engine have been investigated.At low and mid torque levels, an early diesel injection around 60 crank angles degrees (CAD) before top dead center (TDC) was used. At these loads raw NOxemissions was below EURO 6 level (0.2 g/kWh). NOxwas at EURO 5 level over the complete ESC without after treatment and with SCR at high loads it should be possible to reach EURO 6.One issue with DDF is the high HC emission levels.
Att värdera en hamnutbyggnad : en översikt av ekonomiska verktyg samt en värdering av föroreningar
När en kommersiell hamn byggs ut fordras omfattande muddringsarbete för att säkerställa ett brukligt djup för sjöfart. Då stora delar av muddermassorna ofta är förorenade av tungmetaller och miljögifter krävs särskilt omhändertagande av dessa. Traditionella omhändertagningsalternativ består av att deponera massorna på särskild avsedd plats på land eller tippa till havs, något som inte tillåts för förorenade sediment. En relativt ny metod är stabilisering/solidifiering (S/S) som innebär att muddermassorna behandlas med ett bindemedel för att sedan kunna användas som fyllnadsmaterial i exempelvis kajkonstruktioner. Dessa alternativ behöver noga vägas mot varandra med hänsyn till ekonomiska och miljömässiga aspekter.
Fallstudie på växtodlingsgård :
This report will point out the income for a scania plant production farm, this has been
estimated through a case study. The outcome of this report will later be used to
calculate a reasonable leasehold charge.
This case study is solitary based upon this particular studied farm, at this very point,
and can therefore not be used as a general guide. The reason why this particular scania
plant production farm has been selected, is because the author is born and raised at the
farm and has the intention to run the farm in the future.
The chosen farm for this report is based in the southwest of scania and cover 300
hectare of plant production. The crop rotation consists of autumn wheat, sugar beats,
spring wheat, spring barely, winter rape and fallow. The farm owns all machinery
required.
Energikartläggning av ett 1970-tals lägenhetshus på Skarpövägen i Nacka kommun : Simulering av energibesparande åtgärder i ?IDA Indoor Climate and Energy?
This study has been carried out in the spring of 2014 on behalf of PQR Consult AB in Stockholm. The aim of the study has been to analyse the energy usage of the building Skarpövägen 1 in order to explore the possibilites of saving energy by using appropriate equipment. These possible solutions have been simulated by using the programe IDA Indoor Climate and Energy, combined with a life cycle cost analysis. The laundry building, Skarövägen 23, has also been analysed due to its high amount of energy usage. The result of the energy analysis showed that the energy usage was much higher than the energy declaration.
Validering av Casmo-5M / Simulate-3
The objective of this M. Eng. Diploma work was to validate the new version, CASMO-5M, and compare the results with CASMO-4E, by using the same input in both programs. The tasks that were included in this work was to compare TIP-measures, k-effective curves (warm), k-effective curves (cold), the effect of void on k-effective, the isothermal temperature coefficient (ITC), the moderator temperature coefficient (MTC), damping ratio calculations, internal effect in a fuel bundle of a BA-rod, the speed of BA-out burn, impact of xenon, falling control rod, margins and isotopes.The TIP-measures showed that the differences were small for all reactors, at most, 6% nodal improvement by C5M (Casmo-5M) for Oskarshamn 3. The warm measurements of k-effective showed that C5M had a higher value for all cycles of Oskarshamn 1, 2 and 3 in comparison to C4E (Casmo-4E).
