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%.

n this dissertation a comparison of two evolutionary methods for evolving ANNs for robot control is made. The methods compared are SANE with enforced sub-population and delta-coding, and marker-based encoding. In an attempt to speed up evolution, marker-based encoding is extended with delta-coding. The task selected for comparison is the hunter-prey task. This task requires the robot controller to posess some form of memory as the prey can move out of sensor range.

Drinking water is produced from raw water and is either from groundwater or surface water. This thesis aims to find out if the cleaning process of raw water is sufficiently effective. This is important because consumers are otherwise at risk of waterborne infection caused by pathogens. There are three groups of pathogens; bacteria, virus and parasite. These have different characteristics which mean that they require different water treatment to be separated.

Insecticides will be removed from Swedish forestry, at present insecticides are used to treat our seedlings to avoid them from being attacked by pine weevils. With the forthcoming ban on insecticides alternative protective measures will have to be tested. Holmen Forest Ltd has aimed to find an alternative and have developed a mechanic pine weevils protection accessory as well as a new concept on planting pipes. Studies have been conducted on the behalf of Holmen Forest Ltd to see how planting with the newly developed mechanical protectors and plant pipe stands up against the conventional methods used today. The study was conducted over a three week period. Three factors were compared regarding planting quality including i) pressure around the plant, ii) the depth the plant ended up in, iii) plant angle. Mechanical plant pipes were used in the study, and where tested like a one-handed and a two-handed pipe. The study concludes that further development is needed for the mechanic plant protector to live up to the speed and quality of conventional methods.

Today?s wind power plants are only compensated for their reactive power consumption at no-load. As the wind power plants grow bigger the amount of reactive power they need also increases. This is no longer a problem that can be ignored, especially as the net owners are beginning to charge the reactive power they transport.In this thesis a couple of different methods of compensation and their prices will be discussed and evaluated. Problems, such as self-excitation, that can occur if one fully compensates the wind power plant will also be brought to surface.

There are several ways to identify individuals with dry mouth, but there are few studies made in which the different methods have been compared with each other.The aim of this pilotstudy was to compare different methods for identifying individuals with dry mouth. Fifty individuals aged 50 to 75 years were included in this studie. These where randomly chosen among patients at the dental clinic at Kristianstad University College. Four different salivary measurements were conducted: 1) collection of unstimulated saliva, 2) collection of stimulated saliva, 3) the so called ?mirrortest?, and 4) analyse using cottonrolls.

Separation av ko och kalv sker tidigt inom både konventionell och ekologisk mjölkproduktion. Enligt KRAV:s tidigare regler skulle ko och kalv gå tillsammans under råmjölksperioden, det vill säga de första fyra dygnen. Nyligen ändrades reglerna till endast ett dygn och närmar sig i och med det praxis inom konventionell produktion, där djuren separeras omgående efter födseln. Detta innebär en stor kontrast mot nötkreaturens naturliga beteende, där ko och kalv skiljs åt i samband med kalvens könsmognad eller ännu senare. Studier har visat att den tidiga separationen inom mjölkproduktionen innebär en stress och ett potentiellt välfärdsproblem för både ko och kalv.

No other object is in our constant possession such as the mobile phone. The smartphone has been transformed into a worldwide forum for information-rich exchanges between individuals and companies, by which this rapid access to the smartphone has created and continues to create opportunities in terms of communication. Many researchers of today undertake the challenge of studying the smartphone's role as a marketing channel, and the role of the channel is now undoubtedly central in marketing. However, as the importance of marketing communication increases and despite the fact that survey methods are exceedingly dependent on a channel to fulfill its purpose, namely carry out questionnaires, there has been surprisingly little attention to the study of the channel's role and importance when carrying out surveys. The main purpose of this paper is to investigate whether the choice of a communication channel affects the survey outcome and, if so, further investigate how survey methods differ in terms of consumers' attitude and also their perception of their privacy.

Business development is to bring forth the entirecompany and through effective, market renewalprocesses to create sustainable profitability.1 This mightbe difficult, especially for smaller companies who lackthe experience and also tools to make correct forecast.2The purpose of my thesis is to investigate andexplain how a small business can remain flexible andcreate products in new markets by making the brandappealing and credible.In my thesis I have investigated how a company canextract benefit from its brand and identify the benefitswhich are the most unattended in a new market. Bydoing so, the company can systematically developconcepts for new business opportunities. I hopethat my thesis may provide tools and ease businessdevelopment process for smaller businesses.The purpous of my thesis I have studied theories ofbusiness development, brand and brand extension. Inthese theories I have used existing methods and I havecreated my own methods of business development.Through this thesis I have worked with AvelutionAB (a small that produce products for recoveryand comfort). I tested the theory and methods withAvelution which has resulted in a business developmentstrategy as well as two concepts that show howAvelution in the future might develop its business basedon the benefits Avelution and its products create..

This study investigates whether teachers working with children ages 6 ? 9 are including an LGBTQ perspective in their teaching methods. The purpose is to critically examine sexuality and gender as part of the teaching methods in Swedish schools; whether teachers are working with LGBTQ questions in their classes, and if so, how. The following research questions are answered: Are the teachers incorporating an LGBTQ perspective in their classes, and if so, in what sense?Are LGBTQ questions relevant and of interest in the education?Do teachers feel like they have gained the right tools in their pedagogical education and/or in their workplace to work with LGBTQ questions in their class room? And if so, in what way? The method used is qualitative research in the form of interviews and observations.

The usage of Unmanned Aerial Vehicles (UAV) for several applications has in-creased during the past years. One of the possible applications are aerial imagecapturing for detection and surveillance purposes. In order to make the captur-ing process more efficient, multiple, cameraequipped UAV:s could fly in a for-mation and as a result cover a larger area. To be able to receive several imagesequences and stitch those together, resulting in a panoramavideo, a softwareapplication has been developed and tested for this purpose.All functionality are developed in the language C++ by using the software li-brary OpenCV. All implementations of different techniques and methods hasbeen done as generic as possible to be able to add functionality in the future.Common methods in computervision and object recognition such as SIFT, SURF and RANSAC have been tested..

The purpose of this study is to contribute to our knowledge about what methods? teachers say they use in the work with pupils? early reading acquisition, and how they evaluate the pupils´ reading development. I also like to find out what educational interventions teachers believe that pupils with reading difficulties need, and how they say they work to meet the needs of these pupils. The project is based on the following questions: What methods do teachers say they use in the work with pupils early reading acquisition? What extra resources do teachers consider that pupils with reading difficulties need? How do teachers evaluate children's reading development? In order to answer my questions, I've done qualitative interviews with three teachers, at two schools, in two medium-sized municipalities.

Sustainability reporting in Sweden is a voluntary disclosure action for non-governmental companies. Since 2009 all state-owned companies must however publish a sustainability report according to GRI guidelines and with independent assurance statement. Three different sustainability reporting methods are primarily used: (1) Separate Sustainability Report, (2) Sustainability Report included in the Directors? Report, and (3) Sustainability Report forming part of the Printed Annual Report. The aim of this paper is to explore why some companies choose to publish a sustainability report and identify the motivational factors behind this decision, as well as attain an understanding for companies? choice of reporting method.

When beef calves are weaned abruptly at 5 to 6 months of age this triggers a strong stress reaction, since the animals have not yet untied the bonds to their mothers or stopped suckling. This is displayed as extensive vocalization and restlessness. Attempts to diminish the negative effects of weaning on sucking calves have been showing varying results. The study presented here emanates from the observation that when calves are weaned without human interference they are only prevented from suckling, but are still allowed to have social contacts with their mothers. The hypothesis was that calves weaned in two steps would be calmer, gain more weight, and be healthier than animals that were abruptly weaned. To investigate this, 15 calves where weaned in two stages (Group 2), by fitting the calves with nose tags that prevented them from suckling during 5 days prior to the separation of the cows and calves.

Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.
