The design and analysis of specular radar absorbing materials are investigated throughout the dissertation. Although the topic has been investigated for more than 60 years by many researchers and numerous designs have been proposed, still many technical challenges are remained unanswered. The basic questions are, e.g., the optimal thickness of a design, the possibility of utilization of unconventi
Popular Abstract in German Spannungsgesteuerte Kalziumkanäle haben eine große Bedeutung in vielen elektrisch erregbaren Zellen, wie z.B. in Nervenzellen und pankreatischen beta-Zellen. Hier werden sie folgendermaßen aktiviert: In der Nahrung enthaltener Traubenzucker (Glukose) wird nach einer Mahlzeit über den Blutstrom im Körper verteilt und in die beta-Zellen über Glukosetransporter aufgenommen.Voltage-gated Ca2+ channels are essential transducers of cellular signals in many electrically excitable cells. In the pancreatic beta-cell they mediate controlled Ca2+ influx, which is the final trigger for Ca2+ dependent release (exocytosis) of the blood glucose lowering hormone insulin. Several subtypes of voltage-gated Ca2+ channels are known and the L-type has been found to be the main contri
Popular Abstract in Swedish Syftet med den här avhandlingen har varit att förstå hur grupper av vi och dom skapas och består, framför allt inom utbildning och skola, och särskilt inom gymnasiala Komvux. I vardagligt tal menar människor oftast att dom är invandrare, medan vi är svenskar. Jag har visat att denna uppdelning, som sker nästan automatiskt, är alltför förenklad och svart-vit. Ett undersyThis thesis, set in an educational context (Swedish Komvux, high school adult education), deals with how groups of us and them are constructed, changed and reproduced. In order to understand the processes of us and them I have looked at the interconnections between gender, ethnicity and class utilising participant observations and semi-structured interviews. The main theoretical points of departu
Popular Abstract in Swedish Denna rättssociologiska studie handlar om tvångsomhändertagna missbrukares rättssäkerhet under tiden i vård. Författaren undersöker begreppet rättssäkerhet i förhållande till tvångsvårdens verkställighet på så kallade LVM-hem i syfte att finna en begreppsdefinition som är operationaliserbar vid studier av rättssäkerhetens upprätthållande. Med utgångspunkt i resultaten Compulsory treatment and care is regulated by the Care of Alcoholics and Drug abusers Act (Lag (1988:870) om vård av missbrukare i vissa fall, LVM). The regulation's main purpose is to motivate persons with addictive problems to voluntarily participate in the treatment of their problems. The compulsory care shall continue for a maximum period of six months in special treatment centres (the so-call
A radiocarbon and tephra-dated sediment core from Lifebuoy Lake, located on the north-east coast of Kamchatka Peninsula, was analysed for pollen, spores, diatoms, chironomids and tephra in order to uncover regional environmental history. The 6500-year environmental history of Lifebuoy Lake correlates with the broad regional patterns of vegetation development and climate dynamics with both diatoms
Over the last few decades, increasing rates of change in the structure and function of ecosystems have been brought about by human modification of land cover, of which a major component is vegetation. Metrics derived from linear regression models applied to high temporal resolution satellite data are commonly used to estimate rates of vegetation change. This approach implicitly assumes that vegeta
Popular Abstract in Swedish Med utvecklingen av lasern tillkom ett diagnostiserningsverktyg för forskning inom medicin, biologi, fysik, kemi mm. En laser är i princip en ljuskälla som skickar ut ljus med synnerligen välbestämd färg och riktning. Ljus som har en viss färg kan påverka vissa molekyler och atomer. Under vissa förutsättningar svarar dessa ämnen genom att i sin tur skicka ut ljus i en a
Abstract Due to developments in the last decades in the field of protein production, new technologies for bio-separation have evolved. Especially in the field of affinity chromatography, the search for new ligands is of great interest. Besides the antibodies used as affinity ligands, synthetic ligands were introduced. Textile dyes were a first group to be introduced but despite their selectivity a
Over the last decades or so, artificial neural networks (ANNs) have become one of the most promising tools for modelling hydrological processes such as rainfall-runoff processes. In most studies, ANNs have been demonstrated to show superior result compared to the traditional modelling approaches. They are able to map underlying relationships between input and output data without detailed knowledge
Penningtvätt i stor omfattning kan försvaga förtroendet för finansmarknaden, vilket på sikt kan skada hela ekonomin. Penningtvättslagen är en administrativ lagstiftning som omfattar finansiella- och andra aktörer som riskerar att utnyttjas för penningtvätt eller finansiering av terrorism. Lagen innehåller bestämmelser som dessa finansiella aktörer ska efterleva för att minska risken för att utnyttLarge scale money laundering may weaken the confidence in the financial market, which could harm the entire economy. The Anti-Money Laundering Act is an administrative law that stipulates how financial- and other agents, who face a threat of being used for money laundering and financing of terrorism, shall act in order to reduce the risk of being used in money laundering. Banks are one of the fi
Described as a “paradigm shift” event (Michelson, 2020), the Covid-19 pandemic is challenging all humans activities worldwide. Such disruptive event can be labelled as a crisis, which is described as an episode of uncertainty threatening high priority goals (Sellnow & Seeger, 2013). Despite this critical situation, 206 different relevant elections has been held globally since February 2020 (ID
Producing small, bispecific antibodies Proteins are molecules which come in all shapes and sizes, found in every living being. They are translated from the DNA found in the cells of every organism, and every single protein has different characteristics, which allow them to carry out a number of varied functions. Some proteins emit colors, some proteins move ions in the cell, some proteins receive
I det här arbetet har två parallella marina sedimentkärnar från Inre Egedesminde Dyb i Diskobukten, västra Grönland, undersökts.

Båda kärnorna scannades med hjälp av fluorescencespectrometry (XRF) för att erhålla den elementära sammTwo parallel sediment cores were retrieved from the Inner Egedesminde Dyb marine trench at Disko Bugt, West Greenland. Disko Bugt is the most northern point along the Western Greenland coast where relatively warm Atlantic water penetrates through the West Greenland Current. Both cores were subjected to Xray fluorescence spectrometry (XRF) scanning to obtain the elemental composition of the sedimen
The main purpose of this research is to contribute to sustainable waste management in remote areas of the European Union (EU) by specifically employing the concept of ‘waste hierarchy’ as a mean to reach this goal. The last three decades see the EU waste management approach evolve from pollution control (disposal/end-of-pipe) toward more strategic approach focusing on waste prevention and recyclin
The Panama Canal expansion is an external factor on the tanker freight market that is made to change cargo volumes, channel fee income, the average transit time and might also change or create new profitable transportation routes. Shipowners operating in the region will, in one way or another, be affected by this. For tanker shipping companies like Stena Bulk the challenge is to create robustness
The thesis aims to contribute to the preservation of traditional medicinal knowledge of the Tacana Bolivian native tribe, as well as to the isolation and characterization of antiparasitic metabolites from plants used for the treatment of endemic diseases. A selection of medicinal plants, made in collaboration with the Tacana communities who decided which plants have a specific medicinal propose, w
The number of users and the information transmitted over wireless networks have been growing constantly during the last decades. Nowadays, the pace of this growth is extremely sharp because of the new applications which heavily rely on wireless networks to meet users' demands. Wireless networks infrastructures are constantly developing to meet these demands. Massive multiple-input multiple-output
Land cover governs biogeophysical and biogeochemical feedbacks between the land surface and atmosphere. Holocene vegetation-atmosphere interactions are of particular interest, both to understand the climate effects of intensifying human land use and as a possible explanation for the Holocene Conundrum, a widely studied mismatch between simulated and reconstructed temperatures.

Sverige har två olika sanktionssystem som kan aktualiseras när en person exempelvis kört bil under påverkan av alkohol. För en och samma gärning kan en person i två olika förfaranden få ett bötesstraff eller till och med fängelsestraff men även få sitt körkort återkallat av Transportstyrelsen. I svensk rätt har vi principen res judicata som innebär att en person inte får bli föremål för rättsligSweden has two different systems of sanctions that may arise when a person has committed a serious offense in traffic. For the same conduct a person can in two different proceedings be sentenced to pay a fee or even imprisonment and also have his driving license withdrawn by the Transport Agency (Transportstyrelsen). In Swedish law the principle of res judicata is to prevent a person from being
