Implementering av konstruktionsändringar inom ett globalt företag : En fallstudie på en indisk produktionsenhet
Långtidsbehandling med ventilator utan tillräcklig befuktning kan torka ut en patients luftvägarmed olika komplikationer som följd. Målet för detta examensarbete var att utveckla en ny teknikför att befukta och värma inandningsgasen. Ett fungerande koncept och en prototyp som styrkerkonceptet skulle tas fram.Marknaden för befuktare studerades och de vanligast använda befuktningsmetoderna granskadesför att hitta svagheter som behövde åtgärdas. De två vanligaste befuktartyperna är HeatedHumidifier och Heat and Moisture Exchanger. Den främsta nackdelen med Heated Humidifiervar dess tendens att övermätta luften med kondensutfällning som följd, och med Heat andMoisture Exhanger att inte tillräckliga fukt- och temperaturnivåer nåddes.Därför togs en ny design fram med målet att kunna styra fukt och temperatur oberoende avvarandra.

Termisk hantering av litium-jon- batterier i elektriska drivsystem
The automotive market is currently undergoing a historical change where stricter emission legislations and ever increasing fuel costs have intensified the search for effective alternatives to the conventional internal combustion engine, which has resulted in a substantial trend towards electrification of powertrains. Storage of electrical energy is the fundamental component in this technology where the lithium-ion batteries are currently considered as the most appropriate solution. Lithium-ion batteries, however, as other types of batteries, can only be used efficiently and durably within a specific temperature range.This Master thesis has been carried out in collaboration with Electroengine in Sweden AB, situated in Uppsala, which has an ongoing project regarding development of a modular battery system for electric powertrains. The project is at a stage where an initial prototype has been developed which provides the foundation for this thesis. The study has addressed the battery system performance from a thermal perspective, in order to validate the ability of the system to create a thermally serviceable environment for the lithium-ion battery cells.

Riktlinjer för enskilt avlopp : Underlag för bedömning av normal och hög skyddsnivå i Köpings kommun
In Sweden, the eutrophication of lakes, water courses and the coastal areas is considered the major threat to aquatic ecosystems and therefore actions taken to reduce the nutrient load to aquatic system including the Baltic Sea has high priority. There are many different sources of phosphorous and nitrogen and domestic wastewater is one contributing factor to the high load. Especially waste water from households that is not connected to municipal sewage treatment or a local small scale plant with appropriate nutrient removal efficiency is considered a problem. These types of households are quite common in rural areas in Sweden and in areas where summer houses has been converted to permanent living. Swedish legislation now permit the municipalities to decide in which areas within the municipality higher demands of the local small scale treatment facility should be met by the households (i.e.

Pellets - en framtidsmarknad?
With higher prices for oil and increased focus on fossil fuels impact on the environment the heating sector are searching for alternative fuels. Pellets are a quite new product whose production has risen exponential in recent years. Today there are small-, medium-and large-scale users, where the large-scale consumers are the heating sector. The heating sector is mainly using oil to cover the increased demand during cold periods.
The purpose of this study is to analyze the potential of pellets if it would replace thermal power plants oil and coal. The study will also analyze the economic impact a conversion would mean for a heating plant and if the pellet is a reasonable substitute.
2008 statistics from the Swedish district heating association were analyzed and a calculation was performed to determine how many tons of pellets is needed to replace coal and oil.
Effekter av muskeluppbyggande träning på muskelstyrka och funktionsnivå hos personer med Multipel Skleros: en litteraturstudie
Multiple sclerosis (MS) is one of our most common neurological diseases. The development of the disease often make the affected persons live with it for a long time. There are two types of the disease, the first is a progressive type and the other is relapsing remitting. Strengthening exercises isn?t commonly used as a treatment method although muscle weakness and fatigue are common symptoms.
UTV?RDERING AV APPLICERINGSTEKNIKER MED LASCAUX 303 HV Adhesivet Lascaux 303 HV anpassningsbarhet vid strukturella ?tg?rder p? m?leri p? duk
Lining techniques such as nap bonding and mist lining were developed in the late 20th century and
have gained popularity alongside with the increased use of acrylic emulsions as adhesives. The ability
of the adhesive to create a nap bond to the canvases without penetrating the fibers has shown
advantages regarding reversibility. In addition, the use of moisture, heat and pressure is reduced,
which can be advantageous for more sensitive paintings. These lining techniques have been included
in several studies where reversibility, minimal intervention and respect for the individual requirements
and problems of each object have been the focus. The adaptability of the methods has been confirmed
and to further explore the adaptability, this study consists of three simpler application techniques with
the adhesive Lascaux 303 HV on mockups.
VVA-strategier för avgastemperaturhöjning på en HD-Dieselmotor
Regulations on the exhaust emissions of HD-diesel engines are becoming more and more stringent, and therefore, emission after-treatment systems are commonly used. These systems rely on catalytic conversion of NOx,CO , and HC emissions, and are thus dependant on temperature. At low load of the engine, exhaust temperatures are not sufficient for the after-treatment components. Therefore, means to increase the exhaust temperature while maintaining low emissions and fuel consumption are needed.The focus of this project has been to develop strategies for the lift profiles of exhaust and intake valves in the engine, with the goal to raise exhaust temperature in combination with low emissions and fuel consumption. The strategies have been tested in a single-cylinder research engine equipped with a hydraulic variable valve actuation system.
Multipel Skleros En kartläggning av infektionskomplikationer i samband med hematopoetisk stamcellstransplantation
ABSTRACTMultiple sclerosis (MS) is the leading cause of adult disability inSweden. Hematopoietic stem cell transplantation (HSCT) can be used as a treatment option for patients with MS where the disease has an aggressive course. The treatment is preceded by high-dose chemotherapy which lowers the patient's immune system. It is therefore of interest to study infectious complications associated with HSCT in this patient.Aim: The purpose of this study was to identify infection problems in this population associated with HSCT, and to study differences in infectious complications between this group and patients diagnosed with lymphoma who have undergone the same treatment.Method: The study was a retrospective descriptive study with quantitative data. A medical record review was conducted.
Odlingens och lagringens inverkan på utsädes grobarhet :
At seed-growing the aim is to produce a commodity with high germination capacity, good soundness
and purity, and also slight admixture of seeds from other species. The capacity of germination and the
vigour of the seeds may become impaired in consequence of mechanical damage, infection of diseases,
growth of mould, attacks of vermin, high drying temperature, secret germination, sprouting in the ears
etc. The germ belongs to the outer and most unprotected parts of the seed, and consequently this is
much exposed. Even quite sound seeds can instantaneously have low capability of germination. It can
be due to the fact that the seeds are in rest of germination, i.e.
Kännedom om och handhavande av Vocal Cord Dysfunction : bland logopeder och läkare i Sverige
Vocal Cord Dysfunction (VCD) is characterized by paradoxical vocal cord movement during inspiration or expiration, and generally affects adolescents and predominantly women. Previous studies have shown a large inconsistency concerning terminology, definitions, etiology, assessment, differential diagnosis, co-morbidity and treatment. The purpose of this study was to map knowledge on and management of VCD in Sweden. The study was conducted as a written survey addressed to speech-language pathologists and physicians, and attained an answer percentage of 79 percent. The results showed that several professions were involved in the management of these patients, but no clear pattern of referral could be observed.
Frequency of unsuccessful milkings in automatic milking rotary : effect on milk yield, lactose content and somatic cell count at udder quarter level
Developments in milk production are heading towards fewer but larger herds where the milking process is often fully automated. Automatic milking systems were launched in the 1990?s and in the year 2010 the Automatic Milking Rotary (AMR) was introduced. As a rule there are no supervision personnel present during the milking event in systems with automatic milking. This means that there is a risk that cows can be incompletely milked in one or more udder quarters, for example if the robots fail in attaching the milking cups or if the cow kicks off the milking unit.
Jämförelse mellan våtkompostering och andra VA-system i omvandlingsområden : en fallstudie i Norrtälje kommun.
Eutrophication of the Baltic Sea and Swedish lakes remains a major problem despite many years of effort to reduce the emissions of nutrients. One major source is waste water systems, especially private sewage systems. These sewages accounts for a very large share of nutrients per capita in comparison with citizens connected to larger sewage treatment plants. Norrtälje community has the greatest number of private sewage systems in Sweden. Discharges of nutrients, especially phosphorus, to the Baltic Sea from these sewage systems are significant.
