The purpose of this bachelor degree thesis is to analyze technical issues associated with an implementation of a low sloping trash rack with narrow spacing. A hydropower plant in Umea?lven was used as a case study. The basis for the study was a model where trash racks were dimensioned for inclinations between 25 and 45 degrees. Corresponding head loss, durability and water speed through the rack were then determined for each inclination.

During 2006 an estimated number of 150 persons are supposed to have been killed in road accidents caused by speed limit violations. Through Automatic traffic security control (ATK) the Swedish road administration (Vägverket) is working towards lowering the number of speed related accidents. By placing the speed cameras on roads they've managed to lower the average speed at those places. The enlargement of the number of speed cameras is based upon knowledge about for example how high the risk is for speed related accidents on the roads. The speed cameras always measure the speed in which every vehicle passes, but aren't constantly activated to register speed violations.

An often encountered problem when implementing a mass flow regulator in a rolling mill is the one with measurement of speed. The most widely used solution is to fit a pulse counter to a wheel that is in contact with the strip. Common problems with this design are for instance scratch marks on the strip and problems with the flatness measuring system.  One way of circumventing the aforementioned problems would be a non-contact measuring system. The market of today only offers systems based on the Doppler principle.This report evaluates three different systems for non-contact speed measurement. Important areas in the evaluation have been the ability to operate under normal rolling conditions, integration in existing control system and how well the sensor can be fitted to the rolling mill.

The 22q11.2 deletion syndrome is a common genetic disorder that affects for example the heart, palate, immune system and hearing and therefore affects a child?s development. The purpose of this study was to investigate the proportion of children (0-18 years) with 22q11.2 deletion syndrome who have a hearing loss. A retrospective study of 103 children diagnosed with 22q11.2 deletion syndrome was conducted by medical records. Of the 103 children, 51 were boys and 52 were girls.

The idea behind this project came from a feed study executed two years during the lambing season. Both years wool loss was experienced. Low temperature in combination with shearing was believed to cause the wool loss the first year, while protein deficiency was believed to be the cause the second year. In the literature many causes of wool loss are described; mechanical wear, telogen effluvium, bacterial dermatitis, external parasites, wool break, scrapie, genetic causes and nutritional deficiencies are some examples. The aim of this thesis was to study causes for wool loss and how common wool loss is in Swedish sheep herds.

This report describes a study, description and testing of parts to an application adapted to the operating system Android. The application is supposed to measure the distance to a car ahead. Apart from distance measurements the ability of the application to calculate its own speed with the help of GPS is tested. From these two parameters, speed, distance and some constants the theoretical stopping distance of the car will be calculated in order to warn the driver if the car is too close to the car ahead in relation to its own speed and stopping distance.Tests were conducted on the different applications that were programmed and the result showed that the camera technique in the mobile phone itself limits the maximum distance of the distance measurement application. The max distance the tests in this thesis revealed was approximately 5 meters.

The purpose of this study was to examine how five mothers experience and cope with theloss of their adult children and also how this loss affect the mothers. We chose a qualitativemethod using semistructured interviews. We used Lazarus and Folkman?s coping theoryand Folkman?s revised coping theory in our analysis. The results showed that the mothers?experiences were very individual.

The purpose of the study was to examine what methods and strategies individuals use to maintain their weight loss. Another aim was to explore which factors can complicate or simplify weight loss maintenance. Fifty-four individuals who had maintained their weight loss more than a year, participated by answering a questionnaire. The questionnaire was constructed and distributed through the internet. The answers were registered in the program google docs.  The participants mentioned successful methods and strategies, such as exercising regularly, the majority exercised 30 minutes at least five times per week.

A stay in the neonatal intensive care unit of greater than 5 days is one of the identified risks ofa sensorineural hearing loss. Preterm infants usually have at least one risk factor for hearingimpairment. The period from 25 weeks' gestation to 5 to 6 months of age is most critical tothe development of the auditory system. We think it is important to investigate hearingimpariment among infants born preterm, degree and type of hearing loss, risk factorsassociated with hearing loss and how the auditory system may be affected by preterm birth.ObjectiveA critical review of the current literature including studies of preterm infants born betweengestonal age 25-37. Our aim is to identify the most common type and degree of hearing lossamong infants born preterm and if there is an association between hearing loss and pretermbirth.MethodA literature search of Scopus and Pubmed resulted in 16 articles from 2000-2015ResultsMost of the infants in this study had a severe to profound sensorineural hearing loss.

The purpose of this thesis is to test whether firms have target capital structure, and if so with what speed they adjust toward this target. Findings that support this purpose are also in line with the trade off theory. One of the key elements of this thesis is the method used, which successfully enables fulfilling the purpose. The panel data method captures the data characteristics of the cross sectional and time series dimension. By using this approach the dynamic effects of capital structure can be studied, thus if there actually is an adjustment towards a target the speed can be estimated.

A great amount of todays drivers? are constantly exceeding the speed limits on the roads. As a consequense of this, a large number of speed redusing devises, for example speed bumps, has been built around the country. As reports in local medias point out, the acceptance for these types of speed reducing devises, differs and there are many thoughts about location, construction and effect on the traffic safety. This paper approaches the complexity of these problems from the drivers? point of view, based on literature studies and a questionnaire. The goal is not to argue for or against speed reducing devises, but to try to find the source of annoyment and how to proceed further. Some of the problems turned out to be easy to fix, for example porly marked speed bumps.

Objective: 1.4 million people in Sweden state that they are having problems with hearing and the majority havehad no contact with the hearing rehabilitation services. To have a hearing loss seems to be associated withseveral negative attributes. This could be due to bad attitude and insufficient knowledge on hearing loss intoday?s society.Purpose: The purpose with this study was to map the adult populations attitude towards hearing loss and selfratedknowledge of hearing with a survey.Methods: A web survey was made for this study. An official link to the survey was shared from two Facebookaccounts to a total of 997 contacts and a total of 247 responses were collected.Results: The majority of the respondents have estimated their general knowledge of hearing to fairly extensivefollowed by very small.

In today?s society the average person is flooded by information from everywhere. This is in particular the case when using the Internet; consider for a moment the fact that a decent search engine at this moment scans 8 058 million homepages. For a user that repeatedly comes back to the same site, the case is often that they know what they are looking for. The problem is to isolate the important information from all the other information embedding it.We would like to state that we have found one possible solution to this problem, where the user himself can define what information he is looking for at a specific server, then scan the server when visiting it with his browser.

The study was conducted with an landscape approach with an subject related approach in the field of environmental psychology to investigate how road design affects drivers' choice of speed. The purpose was to portray road environments on thoroughfares in urban areas to motivate motorists to keep the speed limit and thus increase road safety for vulnerable road users. The task question was formulated, how can thoroughfares in suburban settings be portrayed to motivate motorists to reduce speed? The study was conducted throughout a literature review of motivational speed measures along with interviews with road design experts at the Swedish Transport Administration. Case studies were conducted on three thoroughfares in the Stockholm suburbs Vallentuna, Upplands Väsby and Danderyd.
