The isolation of male and female DNA is an important step in the analysis of sexual assault evidence. A vaginal swab with female epithelial cells and male sperm cells is obtained from the female, and it is vital to separate the male and female fractions in order to obtain a single-source DNA profile of the suspect. In the case of a low abundance of sperm cells, it is very important that no cells a

This book chapter introduces the reader to an anthology of reportage, essays, eulogies, poems, proclamations, drawings, photographs, letters and more from the most chaotic phase of China’s Cultural Revolution. Entitled A Heroes’ Register, it is one of no more than a handful of surviving self-documenting accounts by the ‘dictating masses’ themselves of the ‘dictatorship of the masses’, as the Maois

This thesis presents new results on fast correlation attacks on stream ciphers. In particular, fast correlation attacks on stream ciphers containing linear shift registers with an arbitrary number of taps, are considered. A general introduction to stream ciphers and correlation attacks is given. The introduction also presents standard properties of linear feedback shift registers and Boolean func

Popular Abstract in English The eye is a complex device in charge of producing clear and sharp images of the outside world. While some people need glasses early on in their lives, others have nearly perfect vision until, all of a sudden, they have to hold books or documents further and further away from their eyes to be able to read them and eventually have to resort to reading glasses. This visuaHealthy eye lenses are transparent and flexible, able to adapt shape in order to focus on far away and close-by objects. With age, however, this flexibility is lost, leading to a condition known as presbyopia. This vision disorder where close-by objects appear blurred commonly starts around the age of 40. The aim of this thesis is to elucidate the molecular origin of the gradual hardening of the c

This thesis addresses the theory and implementation aspects of iteratively decodable codes. Iteratively decodable codes include, in particular, Gallager's regular low-density parity-check (LDPC) codes, Tanner's generalized LDPC (GLDPC) codes, turbo codes due to Berrou et. al. and expander codes. In common, these codes have sparse parity-check matrices, a very particular graph representation and

This thesis gives some background information on environmental issues as the scientific community at large currently sees it. It tries to relate the plethora of current combustion technologies which may be used in gas turbines to those issues. Some basic principles on combustion design are given. Different candidate fuels for gas turbine combustion are discussed. Combustion of bio-fuels is treated

The potential of using security systems for adding value to business bears similarities to the capacity that Data Warehouse and Data Mining offers. Reviewing the literature on documented factors for successful data warehouse adoption and implementation points in the direction of where the future possibilities and challenges lies in adoption and implementation of “value adding” security systems. Th

Popular Abstract in Swedish Upptäckten av Helicobacter pylori (Hp) (1982) har revolutionerat synen på uppkomsten av såväl magsår, magkatarr som magsäckskancer. Idag vet vi att Hp är en mycket starkt bidragande orsak till samtliga dessa sjukdomar och är en av våra vanligaste sjukdomsframkallande bakterier. Epidemiologiska studier har visat att mellan 50 och 80% av jordens befolkning är smittad. I SHelicobacter pylori and Borrelia burgdorferi s.l. can cause chronic infections by evading the immune system. These two human pathogens express a number of immunogenic cell surface proteins. The aims of this study were to gain further knowledge about these antigens and to analyse the serum antibody response in infected individuals. Both invasive and non-invasive diagnostic methods are available for

This paper provides a systemic analysis of complex dynamic issues associated with resource use, scarcity and efficiency by applying systems thinking with respect to sustainability criteria. Casual loop diagramming methodology is adopted to create a conceptual model to better understand the interconnected patterns, cause effect relations and feedbacks between the three dynamic complex systems that

The studied bump stop is a hollow folded polyurethane cylinder mounted around the damper rod in a MacPherson front wheel suspension, restricting the upward wheel displacement. It is a critical component for durability since the force transfer through the bump stop determines the vertical peak loads to the car body. In extreme load cases as driving over a curb, the bump stop is subjected to impact

Abstract A major change in paradigm is taking place in the operation of wastewater treatment plants as automatic process control is becoming feasible. This change is due to a number of different reasons, not least the development of online nutrient sensors, which measure the key parameters in the biological nutrient removal processes, i.e. ammonium, nitrate and phosphate. The thesis is about rea

Popular Abstract in Swedish Enkla kolväten och koldioxid är kemiskt stabila föreningar med mycket låg reaktivitet. På grund av en god råvarutillgång finns ett stort intresse för aktivering och omvandling av dessa föreningar till mer förädlade eller användbara produkter. Reaktioner som bryter starka intramolekylära bindningar är vanligtvis svåra att genomföra på grund av en alltför hög energibarriäAs the tridentate chelate complexes referred to as pincer complexes have expanded their scope as homogeneous catalysts, there is an increased interest in electronic and steric fine-tuning of such complexes. One accessible variable in this aspect is the hybridisation of any coordinated carbon atoms. This thesis describes the synthesis of bis(phosphine) and bis(phosphinite) PCP pincer complexes with

In 2014, more than 200,000 refugees and migrants fled for safety across the Mediterranean Sea. Crammed into overcrowded, unsafe boats, thousands drowned, prompting the Pope to warn that the sea was becoming a mass graveyard. The early months of 2015 saw no respite. In April alone more than 1,300 people drowned. This led to a large public outcry to increase rescue operations. Throughout this period
