Fires can be an important hazard for the overall safe operation of nuclear power plants. Prevention of fire, fast detection and efficient extinguishment of a fire are some parameters, which are important to consider when designing the fire safety in a nuclear power plant. As an alternative to extinguishment system the use of hypoxic air or hypoxic air venting has been introduced e.g. in storage ro

For small deformations a crack/interface model that considers general 3D normal and shear loading is proposed. It involves elasticity, plasticity and damage and it is thermodynamically based. An essential feature of the model is its consistency with the concepts behind the fictitious crack model. In particular, no crack deformation occurs before the crack is initiated and when a crack has just bee

Motion estimation in a series of consecutive images is used in a variety of areas, e.g. video compression and investigation of tissue characteristics and organ function in medical images. Several methods exist both for estimating motions on a pixel level, e.g. block-matching in which two blocks in consecutive images are compared by an evaluation metric, and on a sub-pixel level. In this paper, we

Deep sternal wound infection (DSWI) following cardiothoracic surgery is a rare but potentially life-threatening complication with high morbidity and mortality. DSWI is associated with a significant increase in the length of hospital stay and the cost of hospitalization. The socioeconomic impact of DSWI is considerable. Conventional treatment includes reexploration, surgical debridement, mediastin

Socio-technical methods advocate a human-focus analysis that reflects on social and technical factors in the design of organizational systems. The aim of this paper is to report on the experiences of a ST toolbox use in practice by 36 companies. Our findings show that the use of ST toolbox improves companies’ understanding of their job practices and enhance their learning about their business sust

Methane (CH4) emission from boreal, arctic and subarctic wetlands constitutes a potentially positive feedback to global climate warming. Many process-based models have been developed, but high uncertainties remain in estimating the amount of CH4 released from wetlands at the global scale. This study tries to improve estimates of CH4 emissions by up-scaling a wetland CH4 emission model, PEATLAND-VU

This article is devoted to introduce a new class of nonassociative algebras with involution including the class of structurable algebras.

Popular Abstract in Swedish Diabetes mellitus är en samling sjukdomar som karaktäriseras av förhöjt blodsocker. Traditionellt har man delat upp sjukdomen i två former; typ 1 och typ 2 diabetes. Vid typ 1 diabetes förstörs de insulinproducerande β-cellerna i bukspottskörteln av kroppens immunförsvar och sjukdomen debuterar ofta tidigt i livet. Typ 2 diabetes, tidigare ofta benämnd ”åldersdiabetes” Inadequate insulin secretion is a central component in the development of Diabetes Mellitus, resulting from reduced pancreatic β-cell mass, as well as diminished β-cell function. Islet produced 5-hydroxy tryptamine (5-HT) is suggested to regulate insulin secretion and β-cell mass in rodents during pregnancy and in metabolically challenged states. However, the role of 5-HT in control of insulin rel

Serine/arginine (SR) protein-specific kinase (SRPK), a family of cell cycle-regulated protein kinases, phosphorylate SR domain-containing proteins in nuclear speckles and mediate the pre-mRNA splicing. However, the physiologic roles of this event in cell cycle are incompletely understood. Here, we show that SRPK2 binds and phosphorylates acinus, an SR protein essential for RNA splicing, and redist

Background: Transanal endorectal one-stage pull-through (TERPT) procedure in children with Hirschsprung’s disease (HD) is frequently used worldwide. In order to give the families realistic expectations and to plan the medical care for the years after TERPT, the long term outcome is of great importance. Aim: To collect information on the long term outcome reported after one stage TERPT procedure fo

We propose a sender-specific blockmodel for network data which utilizes both the group membership and the identities of the vertices. This is accomplished by introducing the edge probabilities $(\theta_{i, v})$ for $1\le i\le c, 1\le v\le n$, where $i$ specifies the group membership of a sending vertex and $v$ specifies the identity of the receiving vertex. In addition, group membership is conside

Attention deficit/hyperactivity disorder (ADHD) is characterized by inattention, impulsivity, and motor hyperactivity. Several lines of research support a crucial role for the dopamine transporter (DAT) gene in this psychiatric disease. Consistently, the most commonly prescribed medications in ADHD treatment are stimulant drugs, known to preferentially act on DAT. Recently, a knock-in mouse [DAT-c

This article discusses the political use of the fall of the Roman empire and in particular the way this historical motif has been utilized in environmental debates and in US political culture. It is furthermore argued that the historiography of the fall of the Roman empire bears witness to the ideological and existential contexts of specific explanations to why Rome fell.

This paper investigates algorithmic properties and overall performance of the exact auction algorithm in Demange, Gale and Sotomayor (J. Polit. Economy 94: 863-872, 1986) or DGS for short. This task is achieved by interpreting DGS as a graph and by conducting a large number of computer simulations. The crucial step in DGS is when the auctioneer selects a so-called minimal overdemanded set of items
