The results of a search for an excited bottom-quark b* in pp collisions at root s = 7 TeV, using 4.7 fb(-1) of data collected by the ATLAS detector at the LHC are presented. In the model studied, a single b*-quark is produced through a chromomagnetic interaction and subsequently decays to a W boson and a top quark. The search is performed in the dilepton and lepton + jets final states, which are c
Hypoxic preconditioning is thought to rely on gene products regulated by hypoxia-inducible factor (HIF)-1. Here, we show that the HIF-1 target gene cyclin-dependent kinase inhibitor 1, p21(WAF1/CIP1), is essential for neuroprotection by hypoxic/aglycemic or erythropoietin preconditioning using wild-type and p21(WAF1/CIP1)-deficient neurons. Furthermore, overexpression of wild-type p21(WAF1/CIP1) o
We report the development of a high-level bacterial expression system for the Alzheimer's disease-associated amyloid beta-peptide (A beta), together with a scaleable and inexpensive purification procedure. A beta(1-40) and A beta(1-42) coding sequences together with added ATG codons were cloned directly into a Pet vector to facilitate production of Met-A beta(1-40) and Met-A beta(1-42), referred t
Rating scales are increasingly the primary outcome measures in clinical trials. However, clinically meaningful interpretation of such outcomes requires that the scales used satisfy basic requirements (scaling assumptions) within the data. These are rarely tested. The SF-36 is the most widely used patient-reported rating scale. Its scaling assumptions have been challenged in neurological disorders
Following the fragmentation of a 550 MeV u(-1)primary beam of Ni-58, time-and energy-correlated gamma decays from isomeric states in neutron-deficient nuclei in the 1f(7/2) shell have been identified using the GSI fragment separator in combination with the RISING Ge-detector array. The results on isomers in the mirror pairs Ti-43(22)21-Sc-43(21)22 (I-pi = 3/2(+) and 19/2(-)), Cr-45(24)21-Sc-45(21)
This doctoral thesis explores the implications of establishing tradable certificate schemes for improving energy efficiency (so-called ‘Tradable White Certificate’ [TWC] schemes). Carrying out different case studies, a set of complementary evaluation methods is applied in conducting ex-ante and ex-post evaluation studies. To analyse the attributes and complexities of TWC schemes, the thesis focuse
We have compared the predictions of ligand-binding affinities from several methods based on end-point molecular dynamics simulations and continuum solvation, i.e. methods related to MM/PBSA (molecular mechanics combined with Poisson-Boltzmann and surface area solvation). Two continuum-solvation models were considered, viz. the Poisson-Boltzmann (PB) and generalised Born (GB) approaches. The non-el
This paper investigates the gains harvested through base station cooperation in the up-link for a multi-user (MU) Multiple-Input Multiple-Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) system, operating in a real indoor environment. The base stations perform joint detection using an iterative receiver that carries out multi-user detection and channel estimation via soft information
A tree-ring-width chronology of Pinus tabulaeformis from Kalaqin, Inner Mongolia was developed using modern dendrochronological techniques. Based on the results of correlation function analysis, the total precipitation from the previous August to current July was reconstructed for 1771-2008 AD with an explained variance of 49.3%. The reconstruction correlated well with the dryness/wetness series d
The cliff-edge hypothesis introduces the counterintuitive idea that the trait value associated with the maximum of an asymmetrical fitness function is not necessarily the value that is selected for if the trait shows variability in its phenotypic expression. We develop a model of population dynamics to show that, in such a system, the evolutionary stable strategy depends on both the shape of the f
The 2009 Kidney Disease: Improving Global Outcomes (KDIGO) clinical practice guideline on the monitoring, management, and treatment of kidney transplant recipients is intended to assist the practitioner caring for adults and children after kidney transplantation. The guideline development process followed an evidence-based approach, and management recommendations are based on systematic reviews of
Populärvetenskaplig sammanfattning: Kvävekoncentrationen i den gröna biomassan hos vegetation är involverad i många olika biokemiska processer i det terrestra ekosystemet. Till exempel så påverkar den fotosyntesen, förmultning och evaportanspirationen, för att nämna några. Därför är den också ofta en av grundparametrarna och drivkraften i olika ekosystem-modeller. Att mäta kvävehalten hos blad/barNitrogen in the green biomass of vegetation plays an important role in many biochemical processes in the terrestrial ecosystems, and often used as an input parameter to ecosystem models. It strongly influences photosynthetic rate, decomposition, and evaportanspiration, to name a few. Measuring nitrogen in field involves a lot of time and money, and it would be valuable if this part of the data col
This thesis examines the relationship between international law protecting refugees and national legislation in Sweden and in the UK. International protection is afforded by the 1951 Geneva Convention Relating to the Status of Refugees. But also general international human rights instruments are relevant. These include the Universal Declaration of Human Rights, the International Covenant on Civil
Despite the worldwide importance of entrepreneurship, economic research on this topic has been only fragmented so far. Therefore, the goal of this study was firstly to find a common ground between the established neoclassical, endogenous and institutional growth frameworks on the one hand and the entrepreneurial school on the other hand. For this purpose the distinctive models developed by Solow,
The bachelor thesis contains a presentation of three NGOs working for sustainable housing and infrastructure development for the low-income families in Costa Rica and Nicaragua and the future prospect of introducing a wider range of multi-storey buildings. A high number of the Central American population live in densely populated slums in urban areas with harsh living conditions far below the pove
Large and strongly growing organizations tackle the issue of finding a way to decide which business requirements to fulfill and which projects to move forward but often forget the strategic. Once a strategy has been developed, its implementation appears to be seen as a matter of operational detail and tactical adjustment. As efforts and resources risk to be put on the wrong projects, how do you ma
Background: Customers for buses and coaches on the European market ask for complete vehicles from one supplier. Since Scania CV are only manufacturing chassis, their sales companies must co-operate with body builders in order to offer a complete product and service backup. This means that the sales companies in connection with every order have to deal with two order processes, one for Scania CV an
Purpose: The purpose of this thesis is to create an integrative understanding of how OBCs are fostered by developing a framework for strategic implementation. Methodology: The chosen method is of an explorative nature with an abductive approach. The authors will develop an integrated OBC framework by synthesising relevant brand community literature. This OBC framework will then be scrutinized by e
We live an increasingly larger part of our lives online. The Internet has fundamentally changed how we find information, buy products, connect with friends and find entertainment such as video streaming and digital distribution of books. The Internet has changed the competitive landscape for many markets. Local sellers suddenly face competition from sellers around the globe, introducing more choic
Antioxidants are compounds present in plant, fruit, and vegetables, and they are known for their medicinal benefits such as anti-carcinogenic and anti-fungicidal activity. Most commonly used methods for extractions of such compounds are lengthy due to mass transfer limitations. This study proposes the use of carbon-dioxide expanded liquids (CXLs) as solvent to improve these limitations. Such solve
