This thesis is made on behalf of SCA's Forestry Division and is a comparison of two bucking simulation tools: Aptan (manufactured by Skogforsk) and Best/upr (from Berget Systemdesign). The data is based on 32 stands from SCA's forests in Norrbotten and Västerbotten. The objective is to compare the simulations created by the tools with the harvested volumes from those stands. Three variables are needed for the bucking simulation; these are the diameter distribution (at breast height), the relationship function between diameter and height, and the taper coefficients. The volumes of five different assortments from the stands are compared.

Softube has developed DSP-card and software for simulation of the sound of old tube amplifiers. The purpose with this thesis is to design a compact amplifier with high power to function together with the DSP-card and build a unit that can replace several other guitar amplifiers. The advantages with that kind of solution could be that it would be cheaper, easier to carry and easier to stor than the real amplifiers. The amplifier that has been designed is of class D type with digital PWM modulator. There is several types of amplifier modules on the market that use analog input signal, but if one of them would be used a D-A converter is needed on the DSP card.

AbstractAim of the study: Aim of the study was to investigate whether there were any connections in time between different parts of care in patients with cardiac arrest and hypothermia treatment and cognitive and physical function six months after cardiac arrest and to investigate neurological outcome related to primary registered cardiac arrest rhythm after six months and if there were any changes in cognitive and physical functions as well as self-related health between discharge from hospital and six months after cardiac arrest.Method: The study included 39 patients admitted to three Swedish hospitals between 2008-2011. Cognitive and physical function was evaluated with Cerebral Performance Cathegory, CPC completed with Mini Mental State Examination, MMSE for cognitive function and Bartels Index, BI for physical function and Euroqol-VAS for evaluating the self-related health.Result:  A significant connection was shown between time to start hypothermia treatment and BI, patients with longer time showed improved physical function after six months.Majority of the participants (66,7 %) had Ventricular fibrillation/Ventricular tachycardia, VF /VT, as primary registered cardiac arrest rhythm and in this group CPC and BI was significant better compared with the asystole /Pulsless Electrical Aktivity, PEA group.CPC, MMSE, BI and Euroqol-VAS were all improved over time.Conclusion: Participants with VF /VT as primary registered cardias arrest rhythm had significant better cognitive and physical function 6 months after hypothermia-treated cardiac arrest compared with participants with asystole/PEA as primary registered rhythm. This shows the importance of access to defibrillators in public places in the society and in hospitals and optimal education of lay people and medical staff. Cognitive and physical function and self-rated health improves over time, which might be a very important reason to convey patients, relatives and medical staff to continue cognitive and physical rehabilitation. Keywords: Cardiac arrest, hypothermia, cognitive and physical function, wellbeeing.

This report evaluates whether normal approximation or resampling is to prefer for estimating the distribution of the sample mean and functions of the sample mean. The evaluation relies on simulation studies. The observations of the sample are allowed to be differently distributed. In the case of sample means they are also allowed to be dependent.For sample means the two approximations behaves very similar. The most important component whether we have a good or a bad approximation is how good the approximations catch the variance of the true distribution.

This report addresses the growing need to adapt the medical healthcare to the new possibilities that can be accomplished by incorporating a web aspect to the personal treatment plans of patients. It describes what implementations that need to be considered in order to successfully convert to a partially web-based treatment.The report also reflects the potential economical gain that can be made by keeping the communication between the patient and the doctor frequent. It also takes into account the personal gain to the patient by increased feedback and easier ways to communicate with their attending physician and thereby increasing the quality of their healthcare and service.The construction of a prototype of the system required is also included in the report as a description of construction and functionality of the prototype along with results and estimated outcome..

This student report is about canine atopic dermatitis It includes a description of the immunologic mechanisms and how the reaction affects the body. The symptoms are various, most common is pruritus, erythema and alopecia and directly associated with the immunologic reaction. The diagnostic process includes symptoms, physical findings, differential diagnosis, intradermal test and serological test. The options of treatment are several and vary for each patient. The report includes hyposensitization, medical treatment such as corticosteroids, antihistamin and cyclosporine, topical treatment, fatty acid supplements and environmental treatment. The prognosis is individual for each patient due to their different response to the treatment. It may take a while to find the right combination of treatments to achieve satisfactory control of the disease..

Ofrivillig barnlöshet är ett stort problem i Sverige idag och av kvinnor i barnafödande ålder är ca 1 av 10 drabbade. De flesta som lider av infertilitet använder sig av medicinsk hjälp som förstahandsmetod. Misslyckas man med den medicinska hjälpen går vissa par vidare med adoption direkt medan andra ser detta som en sista utväg. Adoptionsprocessen, som den oftast beskrivs i media, är en arbetsam process och upplevelsen av väntan är central. Tidigare forskning kring adoption fokuserar mest på adoptivbarns upplevelse.

För många akut sjuka patienter är alarmeringssjukvården och ambulanssjukvården den första kontakten med sjukvården. Därför är det viktigt att dessa patienter prioriteras korrekt i förhållande till sjukdomstillståndets allvarlighetsgrad. Allra viktigast är det när patientens tillstånd är potentiellt akut livshotande, i situationer när tid är liv. Förutom det fysiska hotet kan tiden kännas outhärdligt lång innan ambulansen är på plats. Rädsla för att inte bli hittad och rädsla för att tillståndet ska försämras ytterligare kan innebära en skarp konfrontation med tankar om livets ändlighet.Syftet med studien var att kartlägga om det förelåg några skillnader i prioritering mellan alarmeringssjukvården och ambulanssjukvården, vid uppdrag där ambulanssjukvården bedömt att patienten led av ett potentiellt akut livshotande tillstånd.Alarmerings- och ambulansuppdrag från en region i sydvästra Sverige analyserades i en retrospektiv kvantitativ studie.

This report is a thesis work for a B.Sc. in Forestry at the School for Forest Engineers, SLU. The work was an assignment from Jarlträ AB which is a privately owned sawmill located in southern Småland. The aim of the work was to investigate the economical result of different pricelists and how to adjust different parameters such as length correction to give an optimal result. The pricelists was examined through a computer program (SilviA). The pricelists was made in the program and after that a simulation was preformed with a selection of random sampled trees gathered from the area nearby the sawmill.

The aim of this study was to investigate how maternity and child care was carried out at Regional Hospital in Morogoro, Tanzania as well as how it was perceived by mothers and children. The study was conducted with a qualitative method through observation and interviews. The results of the study showed that the staff knew what they were doing and how they should treat their patients and that they helped them without thinking about preventive measures. The study concluded that people wanted to seek the care provided at the hospital and some people stated that they had confidence in the staff. The people that came to the hospital sought care for various diseases and conditions and they all got medical attention of some sort.

Our essay is about alcohol information given to youths in Helsingborg. It is a research to find out how the message is communicated and how it is presented. The purpose of our study is to find out, why inform about alcohol and if it is taken in a preventive aim. To investigate weather there is any talermade information in the community for youths between 12-18 years old. We also want to know if the given information is destined for a special group/groups or is it for young people in general? Our intention is to find out the meaning of prevently information about alcohol and if it is possible to reach a change in attitudes and behaviour.We use a qualitative method and have interviewed twelve persons with different occupations within medical service, local authorities, public and private schools and voluntary organizations..

What are the competencies and qualifications required by employers concerning the first line executives in medical care? In this paper we aim to scrutinise this question by analysing the significance of terms reproduced by employers in advertisements between 1971 and 2007.Our survey concerns 93 advertisements and two interviews with knowledgeable authorities on personnel administration in the county council of Jönköping municipality, Sweden. Using a theoretical framework developed by Ellström our results point out how the demands of the employer have changed starting in the 1970?s. We set fore, as a way of conclusion, the setting of competency and qualifications required by the employer have not only increased but appears much more comprehensive and far more complex than ever before..
