A mapping of the interactions between a moth sex pheromone component and its receptor

A number of analogues of (Z)-5-decenyl acetate (1), a pheromone component of the turnip moth, Agrotis segetum, have been synthesised and tested by using single-cell electrophysiology, in order to investigate the relationships between structure and activity, and to elucidate the interactions between 1 and its receptor. Molecular mechanics and ab initio quantum mechanical calculations have been used

Mesoporous Silica SBA-15 - Formation, Modification and Application

Several aspects related to the mesoporous silica material SBA-15 have been studied through the use of a wide range of experimental techniques, including low voltage high-resolution scanning electron microscopy, small angle X-ray scattering and nitrogen sorption. This work contains three parts, which are in many ways overlapping. The first part deals with the formation of SBA-15, it is found that a

Bacterial cytochromes P450-Studies on Cytochrome P450 102A2 and P450 102A3 of Bacillus subtilis

Cytochromes P450 constitute a super-family of heme containing mixed function mono-oxygenases that is found in all branches of life. They introduce single oxygen atoms, mostly in the form of hydroxyl groups, into lipophilic substances and thereby render them more hydrophilic and susceptible to further reactions. Little is known about the bacterial cytochromes P450. I have in my thesis given an over

Dispersion and Transformation of Traffic Exhaust Particles in the Urban Atmosphere

Ultrafine particles, their sources and fate in the atmosphere are currently key issues in atmospheric research owing to concern about their effects on human health and global climate. Traffic emissions are a dominating source of ultrafine particles, especially in urban areas. After release into the atmosphere, the particles are subjected to complex dilution and transformation processes that are of

Fire safety on board submarines – crew interventions

This work investigates crew opinions about manual intervention on board submarines and planned new solutions on the new submarine, the A26. The planned solutions include an unmanned aft and the installation of water mist instead of Halon 1301 as fire suppression system. Literature, survey and interviews were used to gather information. The crew routines and previous fire incidents were determined.

Kvinnor som offer . En kritisk studie av svensk dagspress och dess framställning av Kongos kvinnor

Sexual violence is a widespread and severe problem in the Democratic Republic of Congo and hits thousands of civilians each year. In Congo sexual violence is a weapon of war and the women are the most affected. The last few years the sexual violence in Congo has received increased attention from international organizations, as the United Nations and non-governmental organizations, and also from th

Genome-wide structural and functional protein characterization by ab initio protein structure prediction

Very little is known about a considerable part of all proteins and it is time consuming and expensive to study each individual protein to determine its function, structure and cellular role. Proteins retain structural, functional and sequential characteristics from ancestral proteins and hence two proteins that share a common ancestor, i.e. are homologs, will to some extent have similar sequen

Green Ideology and its Relation to Modernity : Including a Case Study of the Green Party of Sweden

This study seeks to disclose some of the scientific and philosophical ideas that inform the green movement and its ideology. These ideas, like the groups that have been attracted to the movement, are seemingly heterogeneous. This is one reason why attaining a generally accepted ideology is proving to be a drawn-out process. A second reason considered here is the perceived anomalies inherent to th

Reformationens huvudfrågor och arvet från Augustinus. En studie i Martin Chemnitz' Augustinusreception

As a co-author of the Formula of Concord, Martin Chemnitz (1522-86) codified the sola scriptura principle of the Reformation, that the prophetic and apostolic Scriptures are the only rule for all Church doctrine. This principle is clearly expressed in Chemnitz' own theological treatises as well, but in his argumentation one is also confronted with an astonishing number of quotations from the Churc

Round Trips to Heaven : Otherworldly Travelers in Early Judaism and Christianity

In the beginning of the Common Era, a number of religious texts were written recounting heavenly journey adventures. These narratives have come to constitute a recurring theme in research regarding ancient religions. Round Trips to Heaven features several early Jewish and Christian heavenly journey texts. Most of them are included in the apocalyptic literature. During the earlier research, the he

Family caregivers of persons with dementia. Experiences of burden, satisfaction and psychosocial intervention.

One of the most common diseases occurring in old age groups is dementia. Caring for a relative with dementia poses many challenges for family caregivers and they bear the main responsibility for the persons with dementia living at home. The overall aim of this thesis, which consists of five community-based studies, was to explore experiences of burden and satisfaction among family caregivers (FC)

Extended Producer Responsibility in Cleaner Production: Policy Principle to Promote Environmental Improvements of Product Systems

The focus of the environmental policy-making has shifted noticeably during the last decade. From having played a fairly insignificant role in the 1980s and earlier, product-related environmental problems have attracted an ever-increasing interest from policy-makers, especially in industrialised countries in North-Western Europe. Considerable attention has been devoted to the concept of extended pr

Threads and Images : The Use of Scripture in Apophthegmata Patrum

This study is devoted to the use of the Bible in the Greek systematic collection of Apophthegmata Patrum (AP). After an introductory survey of earlier research on the use of Scripture in general, and that of AP in particular, the main purpose of the investigation is formulated: to describe how the Bible text is contextualized, i.e., how the text is integrated with the teachings and ideals in the s

Time-resolved X-ray diffraction studies of phonons and phase transitions

This thesis summarizes work in which time-resolved X-ray diffraction has been used to probe crystalline materials, thereby revealing the dynamics of phonons and phase transitions. X-ray diffraction is the standard tool in investigations of structure on the atomic scale. It has been used for a long time, and has successfully helped scientists to find the structure of a wide range of materials. The

Modelling of Drug Release from Reservoir and Matrix Formulations - Multiple Unit Dosage Forms and Swelling and Dissolving Matrix Systems

In this work, mathematical models have been developed describing drug release from film-coated reservoir systems as well as drug release and polymer dissolution from swelling and dissolving polymer tablets. The model derivation of both systems is based on a mechanistic approach. The model describing drug release from reservoir systems, i.e. from single, film-coated pellets, was validated against e

Hjärtats skrifter : en brevkulturs uttryck i korrespondensen mellan Anna Louisa Karsch och Johann Wilhelm Ludwig Gleim

This dissertation examines the correspondence of the 18th-century German authors Anna Louisa Karsch and Johann Wilhelm Ludwig Gleim. The main emphasis of the present study is to demonstrate how readings of Karsch's and Gleim's correspondence shed light on epistolary culture. Particular attention is paid to the notion of epistolary culture as a relatively unrestrained ?experimental setting? for bou

Interest in Material Cycle Closure? Exploring Evolution of Industry's Responses to High-grade Recycling from an Industrial Ecology Perspective

Many anthropogenically-produced or beneficiated materials contained in “end-of-life” products retain a great proportion of the invested manufacturing work when discarded. Very few such materials are reconstituted and applied in new products at the same material inherent quality level as in their first lifetime – a process known as “closed-loop recycling”. In general, industrial society maintains a
