Dagkirurgiska operationer står för en stor del av den operativa verksamheten i dag. Många patienter upplever det fördelaktigt att opereras dagkirurgiskt eftersom det påverkar deras vardag i mindre grad. Syftet med denna studie var att beskriva patienters upplevelse av att vara vaken under en operation i regional anestesi. Inklussionskriterierna var att de skulle ha varit vaken under sin operation, komma ihåg operationen samt vara över 18 år. Tio av de femton tillfrågade valde att delta, åtta var kvinnor och två män i ålder mellan 36 och 72.

Tillståndsmaskiner är vanliga komponenter i många digitala konstruktioner. En vanlig typ av tillståndsmaskin är räknare. Räknare är ofta ganska kostsamma att implementera, med avseende på antalet grindar. För att reducera denna kostnad kan istället en PRBS (Pseudo Random Binary Sequence) användas. Denna byggs upp av ett register där en xor - operation utförs mellan två positioner, som beror på längden av registret.

The task was to design and manufacture a submersible displacement pump working with the wobble plate principle. The main task for the Wobble plate pump is to be used as a sewage pump for smaller households or dewatering pump in environments where small flows and high pressures are acquired. For these purposes ITT Flygt sell a screw pump, PC-Grinder 3068. The hydraulic part of the PC-Grinder is manufactured by a subcontractor. Therefore ITT Flygt wants to evaluate an alternative to their screwpump PC-Grinder, which can be entirely manufactured by them self.

The objective was to examine the frequency of unwanted behaviors in the Swedish feline population and what factors in the environment, inheritance and past life that have an influence on the frequency. SLU?s web poll generator was used to create a web poll which insinuated that it was a poll with objective to make an inventory of the Swedish feline population. I wanted to avoid that only owners to cats with unwanted behaviors answered the poll. The web link to the poll was sent to SLUs students and posted on Internet forums for people interested in cats.

A LED spectrometer has been constructed for qualitative spectrometry using certain wavelenghts. The LEDs and the photodiode are being controlled with a microcontroller that is connected to a computer to power the components and save data. The spectroanalysis made with the LED spectrometer were significantly different to a standard spectrometer, concluding that more analysis should be made until a final product is ready. Some areas of improvements are suggested. .

In this project the task has been to develop a product that will facilitate an operation for personnel working in a sterilization center. The operation is to steer the front of a loading trolley into the chamber of an autoclave, a so-called docking. The moment is complicated because the margins to deviate from ideal docking position and still succeed, is very small.The principal Getinge's desire was that the product could be retrofitted at the customers on their existing systems. One of the demands was that the product should fit two types of trolleys, one with a adjustable working height and one with a fixed working height. Getinge is supposed to purchase the system from a subcontractor who shall manufacture it and the requirement from Getinge is that the cost of purchase mustn't exceed SEK 500Initially principles, solving the problem was developed.

This master thesis was a continuation of a previous study in the diesel exhaust characterization, which is part of the academical work embedded in the EMIR-1 project. The main objective of this thesis work was to finish the installation and make the proper modifications of the particulate mass measuring system located in one of the engine test cells at KTH, in order to be able to measure the mass of the particles from the exhaust of diesel engines.This experiment requires a diluted flow sample from the exhaust that should be sent to the device that makes possible the measurement of particle mass, called TEOM. In the first stage of this project, the objective was to study and make the proper modifications in the existing KTH diluter because there were several problems to obtain a constant dilution ratio from it during tests.This modifications were made and it resulted in a great improvement in the maximum inlet and outlet flow that this diluter can handle. Therefore another modification is proposed for controlling the inlet exhaust flow so it will be possible to regulate the dilution ratio and make it constant along a wide range of engine loads and speeds.The second and most important stage was to make particulate mass measurements possible by analyzing the frequency signal from the TEOM device. The idea was to obtain the frequency of oscillation from the tapered element in the TEOM, and therefore with the proper correlations, be able to predict the particulate mass concentration in the exhaust flow from the engine.An electrical problem in the TEOM circuit was detected and corrected, so the signal that carries the frequency from the TEOM can be analyzed properly.

Coronary artery bypass grafting (CABG) föregås av en väntetid som kan vara påfrestande för patienten i och med att en hjärtkärlsjukdom är ett livshotande tillstånd. Effektivi-sering inom sjukvården har lett till förhållandevis korta vårdtider efter detta ingrepp. Med tanke på den relativt långa rehabiliteringsfas som följer läggs mycket av ansvaret för återhämtningen på patient och dennes närstående i hemmet. Syftet med studien var att belysa det sociala stödet och dess betydelse för patienten i samband med en CABG-operation. Studien genomfördes som en litteraturstudie.

BAKGRUND: CABG blir en allt vanligare åtgärd vid kranskärlssjukdom inom svensk sjukvård. Målet med operationen är att lindra symtom vid kärlkramp och hjärtinfarkt samt att reducera mortaliteten. SYFTE: Syftet var att beskriva patienters emotionella upplevelser under det första året efter en CABG operation. METOD: En allmän litteraturstudie som grundades på kvalitativa vetenskapliga artiklar genomfördes. Resultatet baserades på sju vetenskapliga artiklar som söktes fram via elektroniska databaser och därefter granskades och analyserades.

Bakgrund: En operation leder i vissa fall till on?digt lidande f?r patienten i form av postoperativa s?rinfektioner, hypotermi samt tryck- och nervskador. Forskning visar att det finns samband mellan dessa komplikationer och l?ng operationstid. F?r att undvika dessa beh?vs mer kunskap om vilka faktorer som kan f?rkorta operationstiden.

Among researchers it has been established since decades that humans and animals have an internal biological clock that controls certain physiological mechanisms. One example regarding humans is the impairment of lung function during the night, causing the phenomenon ?nocturnal asthma? among asthmatics. Only a few studies concerning respiratory circadian rhythm in horses have been done previously and they showed a daily variation in horses with a chronic or an acute respiratory disease. The technique used in those studies was the conventional technique, which is invasive and less sensitive than the technique used in this study.

The aim of this thesis is to compare the effectivity of using a natural language and a controlled vocabulary when performing subject searches in the bibliographic database LISA Library and Information Science Abstracts. 20 topics were created and for each topic two searches were made, one by using a query formulated with natural language directed to the abstract field and the other one by using a query formulated with descriptors from the thesaurus in LISA directed to the descriptor field. The average relative recall amounted to 64,8% for the AB-queries and 54% for the DE-queries. Failure analysis showed that the majority of the relevant documents not retrieved by AB-queries could have been retrieved with other query terms, such as synonyms. In a natural language there are many different ways of expressing a topic, and this tends to have a negative effect on retrieval effectivity.

At present indoor tethering of dairy cows is still common but is not predicted to take part of modern dairy production. When conducting scientific studies of cattle it is generally necessary to tether the animals to maintain a controlled environment. Studies confirm that tethering and confinements of cattle severely affects the development of stereotypies in cattle. The feeding regime and feeding level have an immense affect on the stereotypi level in cattle. The aim of this experiment was to study dairy heifers that had never been tethered before the start of the experiment, to evaluate the affect of tethering on the development of stereotypies and the impact of the feeding regime on the behavior of the animals. Sixteen dairy heifers were tethered in a tie stall and divided in two groups with different treatments. Heifers in treatment E were fed restrictedly with silage and treatment EH was fed with the same amount of silage but also straw ad libitum.

The aim with this report was to exam and surveys the internal logistics of Proton Finishing?s production. The basic data should give the company suggestions of more efficient and improved internal logistics. We will also give from our perspective suggestions of improvement, which the company will be able to evaluate.To evaluate these problems we used different kinds of methods. A frequency study was made on the internal forklift.

A number of studies have been made to examine several aspects of voice production in individuals with different types of hearing impairments. Most of the studies were made to explore the impact that hearing aids have for people with severe or congenital hearing impairment. So far it has been confirmed that there are changes regarding voice production in these individuals. A group that has not been investigated regarding voice production to a larger extent are hearing aid users with an acquired hearing impairment. In the present study the voice production of seven individuals, four men and three women, with a moderate acquired hearing impairment is examined.
