The fishing port of Bläsinge is located on the east coast of Öland, Sweden?s second largest island. Today the port has a limited supply of freshwater. The economic association of the fishing port wants to expand their business, so that they will also include tourist services. To do this the harbor will need a more independant source of freshwater, with a higher quality than the present well.

Catecholamines are stress hormones that are produced and released by a rare tumor called pheochromocytoma. This tumor can cause hypertension which if undiagnosed and untreated leads to death. Since good therapy is available, it is important to find the tumor in time. The most common way to diagnose the tumor is measurement of the biochemical markers; catecholamines and their metabolites, methylated catecholamines.After observation that almost all normetanephrine results for women were higher than the upper reference limit and therefore pathological, the accuracy of the present reference intervals was questioned. Therefore new reference intervals for both urinary catecholamines and methylated catecholamines were developed by analysis of 46 samples using HPLC.

Background:Alzheimer´s disease is a so-called degenerative dementia in which brain cells gradually degenerate and die. The disease causes memory disorders and the trait of character disappears. Alzheimer´s disease also affects the related parties that may take a great responsibility. Related caregivers are entitled to support from healthcare. Aim:The aim of the study was to describe the experiences of being related when caring for a person suffering from Alzheimer´s disease.

Background:Alzheimer's disease is a disease that primarily affects the elderly but also younger people. Alzheimer's disease is a type of dementia which means that you get changes in the cerebral cortex and cells gradually die. The disease causes memory loss and things that were obvious before will be difficult for the sufferer. Alzheimer's disease also affects next of kin to a large degree; they will have to take a great responsibility. The next of kin are entitled to support from healthcare.Aim:The aim was to highlight next of kin' experiences of healthcare to their family members with Alzheimer's disease.Method: The study was based on narratives, which in this case means analysis of autobiographies.

Turboaggregat med variabel geometri har länge funnit hos automobiler, men det dröjde ända tills 2008 innan det första dök upp på ett fartyg. Syftet med denna undersökning har varit att kontrollera om de fördelar som Man B&W hävdar att VTA-aggregatet skall ha stämmer, samt att undersöka om VTA-aggregatet kan lösa de problem som uppkommer i och med att man kör med reducerad fart, s.k. slowsteaming. För att undersöka detta har jag bedrivit litteraturstudie, med insamling av data mestadels från Internet.Resultatet av undersökningen visar på att ett VTA-aggregat kan minska bränsleförbrukningen och vissa emissioner vid reducerad fart jämfört med en konventionell turbo av samma storlek. Den minskade bränsleförbrukningen leder i sin tur till ekonomiska vinster.

Hemoglobin is an oxygen binding protein in erythrocytes. Hemoglobin is composed of four polypeptide chains. During the fetal stage the type of hemoglobin called fetal hemoglobin (HbF) dominates. After birth HbF is replaced by adult hemoglobin (HbA). HbF persists in concentrations less than 1%.

The horse is a homeothermic animal and to keep a constant body temperature in winter season is important. Acclimatisation is to provide means for a good thermal insulation consisting of skin, hair, and an outer air layer. The skin covers the horses body and it is composed of three main layers where the top layer of the epidermis consists of dead keratinized cells that are constantly being sheed. The dermis is composed of collagen connective tissue that give the skin its strength. The bottom layer with subcutaneous fat provides a thermal insulation and can be used as an energy reserve in cold weather.

Användningen av personbilar har ökat stadigt i Sverige och världen i stort de senasteåren, vilket lett till ökade utsläpp av koldioxid. Samtidigt har oljepriset nåttrekordnivåer, och många menar att utvinningen av olja redan har nått sin topp. EU hardessutom satt som mål att medeltemperaturen på jorden inte får stiga med mer än maxtvå grader Celsius, och att till år 2050 reducera koldioxidutsläppen med 80 %. Detta ärenbart möjligt om nya, gröna drivmedel och drivlinor fortsätter utvecklas ochframförallt kommersialiseras. Användningen av förnyelsebara energikällor har ökatkraftigt, vilket skapat förutsättningar för bilar drivna av el.

The purpose of this master thesis is to evaluate how internal vehicle information inScania buses and trucks can be used for evaluation of driver performance regardingfuel economy, vehicle wear, traffic safety, emissions and cargo damage. To someextent it was examined whether this information could be used for training the driverto a better driving style. In addition, a prototype for such a system was developed.By first defining what distinguishes a talented driver and how he/she differs from apoor driver, followed by a study of the internal vehicle communication, a system thatin real-time gathers and interprets vehicle data could be developed.The resulting system can with reasonably high reliability detect a number of trafficevents (such as braking, lane changing or hilltops). At each such event, the driver?sbehaviour can be evaluated.

Crypreservation of oocytes is recently being considered to be a valid choice in infertility treatments.Low survival and fertilization rates due to inefficient slow freeze protocols have been the outcome ofmany previous studies done in the field. However, introduction of the vitrification technique and itsapplication in reproductive medicine and to some extent new improved slow freeze protocols haveshown that oocytes can be cryopreserved with successful outcome.In this project the survival rate of oocytes after vitrification with MediCult Vitrification andWarming Media has been studied. Also, a comparison of the carriers Cryoloop (an open system) andCryopette (a closed system) has been performed.A total of 43 oocytes were vitrified and warmed according to MediCult's protocol, of which 21oocytes with Cryoloop and 22 with Cryopette. The cells were post-thaw incubated in a physiologicalenvironment for 24h. During that time the morphology and viability were observed and noted after 2h,over night and after 24h.

Most major companies today have a visual identity. It answers questions like: which font do I use? and when can I use the logo or not? Westinghouse Nuclear Fuel in Västerås have a visual identity but no guidelines for the employees to follow. Further-more, rollups and rollup handouts produced by Westinghouse are not mentioned in the visual identity. ?erefore the external information from Westinghouse is someti-mes, both by employees and customers, perceived as not uniform.

Platelets are important for the healing of damaged blood vessels since they have an importantpart to play in the coagulation process. At the same time, the blood must be kept fluid and notcoagulate at the wrong time. Therefore there are factors that effect the aggregation of plateletsin a positive or a negative way.Previous investigations have shown that platelets during stirring conditions produce reactiveoxygen species (ROS) that weaken the inhibiting effect of nitric oxides (NO) on platelets andthat the drug Dexamethasone (Dex) can reduce the ROS-production.The aim of this project was to investigate if glucocorticoids, in this case Dexamethasone,could restore the inhibiting effect of NO on platelets and if there was any decrease in ROS-production.The result of the ROS-measurements showed a great variance and it was difficult to draw anyconclusions from them, but a clear decrease in ROS, as previous reported, was not shown. In the aggregation experiments the inhibiting effect of NO was observed through the drug S-nitroso-N-acetylpenicillamine (SNAP), a NO-donator.From the aggregation experiments, the result seemed to be that SNAP during longerincubation time lost its inhibiting effect, probably because the cells become desensitized.With superoxid dismutase (SOD), the effect of SNAP increased, both in the experiment withlonger and shorter incubation times. Dex seemed to reinforce the aggregation in relation toboth SOD and SNAP.

Brämhults Juice AB is one of Sweden?s leading producers of fresh fruit juices and drinks. The fruit drinks last 3 days once opened and when stored in a refrigerator kept at 7°C. Since factors that shorten the drinks? best before date are usually not noticed until the entire batch has expired, it would be advantageous to find a way to accelerate the drinks? natural deterioration, so that an unusal short best before date is noticed before more products are shipped off to the stores.

A renewed application for environmental permit for the Hovgården landfill in Uppsala shall be submitted before December 2004, therefore the municipality of Uppsala needs improved knowledge of the contents, mostly organic compounds in the leachate and they also want to find a method to minimize the emissions of these compounds. The purpose of this study was to find a practical and economical method based on chemical oxidation using oxidants. The oxidants investigated are Fenton's reagent, hydrogen peroxide, Oxypro, potassium permanganate and potassium persulfate. The study was made on untreated leachate and leachate that has been treated in an aerated dam followed by sedimentation dams collected from the Hovgården landfill, and alson on sludge water from sludge storage cells. The effects of the five oxidants have been established by analysing the UV absorbance at the wavelengths 253,7 nm and 260,0 nm at different pH values. The UV absorbance was used to indicate the amount of aromatic hydrocarbons in the water. Also analyses of iron and manganese were done after the experiments with potassium permanganate, hydrogen peroxide and Fenton's reagent.
