The Geological Society of America has sponsored versions of the geologic time scale since 1983. Over the past 30 years, the Geological Society of America Geologic Time Scale has undergone substantial modifications, commensurate with major advances in our understanding of chronostratigraphy, geochronology, astrochronology, chemostratigraphy, and the geomagnetic polarity time scale. Today, many part
Popular Abstract in Swedish Avhandlingens övergripande syfte är att kritiskt studera interorganisatoriska samverkansprocesser och sammanhängande konsekvenser, med ett särskilt fokus på rättens och maktens betydelse. Analysen av det empiriska materialet, som speglar samverkan i en kontext av barnahus på sex orter i Sverige (samverkan under ett tak kring utredningar av misstänkta brott mot barn), The overarching objective of the dissertation is to study inter-organisational collaboration processes and their associated consequences in a critical manner, with particular emphasis on the importance of law and power. The analysis of the empirical material, reflecting collaboration in the context of Barnahus on six locations in Sweden (collaboration under one roof regarding investigations of s
In recent years there has been much attention paid to corporate scandals, and in the Swedish media the Skandia incidents have become a serial as, years after the incidents was revealed, sentences are passed on those involved in the scandal. The former president and vice president of the joint-stock company Skandia were both prosecuted for the economic crime gross breach of faith committed by an ag
A high-pressure tank rupture is a challenging scenario requiring attention in most hydrogen applications. A common cause of rupture is an external fire heating the tank, causing increased internal pressure and/or reduction in the tensile strength of the tank material (with the relevance of each depending on tank material).Most of the available methods for prevention of such ruptures have been deveA high-pressure tank rupture is a challenging scenario requiring attention in most hydrogen applications.

Purpose of Review: At elevated levels, the essential element manganese (Mn) is neurotoxic and increasing evidence indicates that environmental Mn exposure early in life negatively affects neurodevelopment. In this review, we describe how underlying genetics may confer susceptibility to elevated Mn concentrations and how the epigenetic effects of Mn may explain the association between Mn exposure e
The discovery of genetic loci associated with complex diseases has outpaced the elucidation of mechanisms of disease pathogenesis. Here we conducted a genome-wide association study (GWAS) for coronary artery disease (CAD) comprising 181,522 cases among 1,165,690 participants of predominantly European ancestry. We detected 241 associations, including 30 new loci. Cross-ancestry meta-analysis with a
The use of Reinforcement Learning (RL) to design controllers for safety critical systems is an important research area. On the one hand, RL can function in and adapt to complex and changing environments without requiring a model of the system. On the other hand, in such systems robustness is of high importance, as well as ways to guarantee and certify a level of robustness. This project investigat
Breast cancer is the most prevalent form of cancer among women in Sweden, with 9 000 diagnoses during 2023. While the five-year survival rate reaches 92.5% due to national screening programs, transitioning from 2D Digital Mammography to 3D Digital Breast Tomosynthesis (DBT) could further improve early detection. However, the high volumes of data increases the examination times, preventing it from
Landskrona has for a long time had problems with high concentrations of Pb and other heavy metals in the air. Measurements investigating the content of airborne particles have been performed in 1977, 1988, 2003 and 2008 and show an influence from heavy industries, traffic in town and transboundary pollution. To investigate the air quality in terms of heavy metals in Landskrona today, the metal con
Icknield Port is one of the largest redevelopment sites in Birmingham, UK and presents a huge opportunity to create a high quality destination of regional significance. Because of its size (30 ha), its locational advantage (1.4 km from city centre) and its unique waterfront attributes, the site offers great potential to meet the aspirational goals of major landowners, future users and the City Cou
Background. Angiogenesis has a key role in several conditions and is regulated by several factors such as the platelet-derived growth factor (PDGF) or the vascular endothelial growth factor (VEGF). The goal of this study was to investigate the possible role of PDGF and VEGF in a group of patients with severe food allergy. Methods. We design a prospective longitudinal study (n = 30) with patients w
Före 2005 dömdes gärningspersoner som sexuellt utnyttjat en person som befunnit sig i ett hjälplöst tillstånd för sexuellt utnyttjande enligt 6 kap. 3 § Brottsbalken (BrB). Endast om det var gärningspersonen som själv hade medverkat till offrets hjälplösa tillstånd kunde denne åtalas för våldtäkt. Föranlett av ett stort missnöje och hätsk debatt i media trädde 2005 den nya sexualbrottslagstiftningPrior to 2005, offending persons involved in sexual exploitation of a person who found themselves in a vulnerable situation, were sentenced pursuant to Chapter 6 § 3 The Criminal Code. Only if the offending person had contributed to the victim's vulnerable situation, could he be prosecuted for rape. In 2005, the new sexual offenses law came into force, which was due to a great dissatisfaction
The advanced research that is being carried out in different science fields today requires advanced technologies; for the study of distant places and hidden elements of our universe tools like The Hubble Telescope, Voyager 2 and the Very Large Array has been to great use. In the same way, a neutron source and its instruments enable scientist to see and understand basic atomic structures and forces.
In this master thesis, combinations of noise-canceling LNA and harmonic-rejection mixers are investigated and compared to find an optimal inductorless receiver front-end for low-band (600-960MHz) FDD LTE-A network. The work was carried out in a modem development project at Ericsson Modems, Lund. Three receiver versions with different harmonic rejection techniques are compared in terms of noise fig
I mars 2015 nådde den globalt genomsnittliga koldioxidhalten 400 ppm för första gången på tre miljoner år. Därför satte den svenska regeringen, år 2017, upp målet att Sverige ska vara klimatneutralt år 2045. Samtidigt står den svenska byggindustrin för 18,1 miljoner ton växthusgasutsläpp, vilket motsvarar 19 procent av Sveriges totala utsläpp. Syftet med denna studie är att undersöka och analyserThe global average carbon dioxide concentration reached 400 ppm for the first time in three million years, in March 2015. This calls for drastic measures so in 2017 the Swedish government set up the goal of making Sweden climate neutral by 2045. Meanwhile, the construction sector in Sweden accounts for 18.1 million tons of green- house gases which is 19 percent of Sweden’s total emissions. The pur

The dominance of men in politics has been a long standing trend, with women historically underrepresented in this sphere. Efforts toward women's inclusion in politics seek to address and rectify this gender imbalance, advocating for greater representation, equal opportunities, and the dismantling of barriers that have hindered women's active participation in political decision-making proce
During 2007, a legal reform in Sweden took place, this change led to complications in interpreting the needs of individuals and the application of the laws by the governing social authorities. The aim of the thesis is to explore the underlying norms that influence social workers interpretation of young offenders needs, aged 15 to 17 years, and if the interpretations are consistent. The aim was ach
A novel volatile microemulsion formed by the catanionic surfactant hexadecyltrimethylammonium octylsulfonate (TA(16)So(8)), heptane and water has been explored as a template for producing nanoparticles of hydrophobic organic materials. Butylated hydroxytoluene (BHT) was employed as the model hydrophobic substance. First, the oil-in-water microemulsion was formed, containing TA16So8 as the single e
Popular Abstract in Swedish Många av alla kemiska processer som pågår i våra kroppar utförs av proteiner. När de inte fungerar blir vi sjuka. I vissa fall, till exempel vid Alzheimers sjukdom eller Creutzfeld Jacobs sjukdom, beror det på att ett visst protein har fel form. Att förstå hur proteiner antar sin slutliga form och vad det har för inverkan på proteinets funktion är således viktigt. ÅVery 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
