BACKGROUND: Female sex pheromones attracting mating partners over long distances are a major determinant of reproductive isolation and speciation in Lepidoptera. Males can also produce sex pheromones but their study, particularly in butterflies, has received little attention. A detailed comparison of sex pheromones in male butterflies with those of female moths would reveal patterns of conservatio
Background-After age, sex is the most important risk factor for coronary artery disease (CAD). The mechanism through which women are protected from CAD is still largely unknown, but the observed sex difference suggests the involvement of the reproductive steroid hormone signaling system. Genetic association studies of the gene-encoding Estrogen Receptor alpha (ESR1) have shown conflicting results,
Three sets of research criteria are available for diagnosis of Alzheimer's disease in subjects with mild cognitive impairment: the International Working Group-1, International Working Group-2, and National Institute of Aging-Alzheimer Association criteria. We compared the prevalence and prognosis of Alzheimer's disease at the mild cognitive impairment stage according to these criteria. Subjects wi
As more and more applications and services in our society now depend on the Internet, it is important that dynamically deployed wireless multi hop networks are able to gain access to the Internet and other infrastructure networks and services. This thesis proposes and evaluates solutions for providing multi hop Internet Access. It investigates how ad hoc networks can be combined with wireless and
Food consumption is one of the main areas of concern if we should become successful in creating a sustainable future. However, there are diverse views on what sustainability is, and consumers have varied knowledge and commitment to consuming sustainable food. The aim of this thesis is to investigate the impact of consumer understanding of food labels on sustainable purchase behaviour and to explor
Despite being their closest evolutionary relatives, chimpanzees have a substantially different brain compared to humans: Homo sapiens display larger and more complex forebrains, although the protein-coding genes between the two species are basically unchanged. Therefore, differences in the transcriptome and in regulatory networks must be further investigated to better understand the dissimilaritie
I ett aktiebolag eller motsvarande bolagsform med begränsat ansvar för aktieägarna står aktiekapitalet i centrum. Lagstadgat krav på aktiekapital har förekommit i somliga rättsordningar. I vissa länder har kapitalkravet eftergetts. I detta arbete kommer att göras en komparativ jämförelse mellan Tysklands, Storbritanniens, Sveriges och EU:s aktiebolagsformer med avseende på minsta kapitalkravet i bIn a limited liability company or similar corporate form with limited liability for the shareholders the legal capital plays an important role. The minimum capital requirements have appeared in some jurisdictions. In some countries, the minimum capital requirement have been abolished. This work will be a comparative comparison between German, British and Swedish companies rules with focus on the m
BACKGROUND: Ecuador is a Spanish speaking country located in northwestern South America with an approximate population of 16 million people. It is considered a developing country. The public healthcare system is divided into three branches and there are also private services available. Musculoskeletal disorders are overly represented in the developing world, especially where poverty and rural livi
Title: Demand forecasting using Artificial Neural Network and demand pattern recognition at Sony Mobile Communication Author: Christopher Duchateau Background: Machine Learning is considered as one of the most important technologies in this era for the society and a possible fundamental driver of economic growth. Furthermore, machine learning technology is characterized to shape a new period in
Through recent years, RNA has rapidly gone from mainly being known as a passive information-carrying molecule within the central dogma of molecular biology to becoming the active ingredient in multiple therapeutics, such as in vaccines and potential drugs against cancer. However, one of the main challenges with RNA as a therapeutic is efficient delivery to cells. Understanding the mechanism throug
Until very recently, Germany belonged to the ‘familialist’ group of welfare states, which offered cash rather than services to married couples and families. Sweden, in contrast, belonged to the ‘non-familialist’ counterpart, fostering gender equality in employment and family care via public services and extended reconciliation measures for decades. During the 2000s, however, Germany eventually enaAbstractUntil very recently, Germany belonged to the ‘familialist’ group of welfare states, which offered cash rather than services to married couples and families.

Purpose: To assess retinal function in combination with the retinal structure in ABCA4-associated retinal degenerations. Moreover, to evaluate the possibility of predicting the natural course of these disorders. Methods: 34 patients with Stargardt disease or cone rod dystrophy carrying confirmed mutations in ABCA4 were selected from our retinitis pigmentosa (RP) register. Sequence analysis of the
In 1997 Sweden was the third biggest exporter of popular music in the world. This astonishing fact has often been explained as being the result of the large investments in municipal music schools that took place in Sweden from 1940. The explanation holds an interesting paradox. Most municipal music schools began with the aim to teach young people appreciate more valuable music (i.e. classical) tha
Objectives: Smoking cessation programmes in which groups of smokers have the opportunity to learn behavioural techniques and benefit from mutual support for quitting are widely available. The aim of this review is to determine the effectiveness of smoking cessation programmes delivered in a group format, for helping smokers achieve long-term smoking cessation. Search strategy: TheTobacco Addicitio
Objectives: : Knowledge of the correspondence between clinical ICD diagnoses and classification criteria fulfilment is crucial to interpret studies identifying cases via ICD codes. We assessed the degree to which patients registered with ICD-10 diagnoses of psoriatic arthritis (PsA) in the Swedish National Patient Register (NPR) fulfil established PsA classification criteria. Method: Four hundred
Increasingly stringent pollutant and CO2 emission standards require the car manufacturers to investigate innovative solutions to further improve the fuel economy and environmental impact of their fleets. Nowadays, NOx emissions standards are stringent for spark-ignition (SI) internal combustion engines (ICEs) and many techniques are investigated to limit these emissions. Among these, an extremely
Purpose - This paper aims to explore the electronic design of the Touch Hand: a low-cost electrically powered prosthetic hand. The hand is equipped with an array of sensors allowing for position control and haptic sensation. Pressure sensors are used on the fingertips to detect grip force. A temperature sensor placed in the fingertip is used to measure the contact temperature of objects. Investiga
Identification and relative quantification of hundreds to thousands of proteins within complex biological samples have become realistic with the emergence of stable isotope labeling in combination with high throughput mass spectrometry. However, all current chemical approaches target a single amino acid functionality (most often lysine or cysteine) despite the fact that addressing two or more amin
Importance: The role of ω-3 polyunsaturated fatty acids for primary prevention of coronary heart disease (CHD) remains controversial. Most prior longitudinal studies evaluated self-reported consumption rather than biomarkers. Objective: To evaluate biomarkers of seafood-derived eicosapentaenoic acid (EPA; 20:5 ω-3), docosapentaenoic acid (DPA; 22:5 ω-3), and docosahexaenoic acid (DHA; 22:6 ω-3) an
