Desertification, climate variability and food security are closely linked through drought, land cover changes, and climate and biological feedbacks. In Ghana, only few studies have documented these linkages. To establish this link the study provides historical and predicted climatic changes for two drought sensitive agro-ecological zones in Ghana and further determines how these changes have influ
There is a growing need to understand how existing concepts and tools for sustainability relate to each other and to a robust, trans-disciplinary systems perspective for sustainability. As a response, a group of scientists, including some of the authors, have developed a framework based on backcasting from sustainability principles over the last 20 years the Framework for Strategic Sustainable Dev
The S 2p core level photoelectron spectra of Sulphurhexafluoride Clusters have been investigated together with heterogeneous Ar/SF6 clusters, created by doping Ar host clusters (with a mean size of 3600 atoms) with the molecule. Surface and bulk features are resolved both in the argon 2p and the sulphur 2p core level photoelectron spectra. For the latter level such features were only observed in t
One major challenge to the improvement of regional climate scenarios for the northern high latitudes is to understand land surface feedbacks associated with vegetation shifts and ecosystem biogeochemical cycling. We employed a customized, Arctic version of the individual-based dynamic vegetation model LPJ-GUESS to simulate the dynamics of upland and wetland ecosystems under a regional climate mode
Background: Genetic factors seem to be of greater importance in prostate cancer than in other forms of cancer. Studies have suggested familial concordance in survival, but the extent to which that is due to tumor characteristics is not known. Objective: We hypothesized that a brother of an index case with prostate cancer is at particularly increased risk of prostate cancer with the same tumor diff
There is a propensity in many languages for elements that represent backgrounded and/or given information to show up in the middle field, a tendency that I term SHIFT. In this paper I argue that Object Shift and the raising of certain adverbials to the middle field in Swedish is due to this general propensity. SHIFT applies across the board, but language-specific principles, such as Constituent Or
High transverse momentum jets produced in pp collisions at a centre of mass energy of 7 TeV are used to measure the transverse energy-energy correlation function and its associated azimuthal asymmetry. The data were recorded with the ATLAS detector at the LHC in the year 2011 and correspond to an integrated luminosity of 158 pb(-1). The selection criteria demand the average transverse momentum of
A central point of departure for this socio-legal study about online hate crimes concerns the significance of analysing and understanding social norms in relation to these crimes on the Internet. This is of importance not least when one approaches the issue of how law and the legal system may contribute towards positive developments in this field and prevent hate crimes. It is apparent that law an
The ground state properties of Mg-31 indicate a change of nuclear shape at N = 19 with a deformed J(pi) = 1/2(+) intruder state as a ground state, implying that Mg-31 is part of the "island of inversion". The collective properties of excited states were the subject of a Coulomb excitation experiment at REX-ISOLDE, CERN, employing a radioactive Mg-31 beam. De-excitation gamma-rays were detected by
The question of the concept of truth in the story of Pelagia,a hagiography about the repentent sinner Pelagia, and other hagiographical texts and in the New Testament is analyzed. It seems that the concept of truth is a rather simple one, and explicit assurances of truth is a sign of a not so trustworthy text.
Popular Abstract in Swedish Populärvetenskaplig sammanfattning Inflammation i struphuvudet kan bero på annat än reflux Bakre laryngit är en form av kronisk inflammation som påverkar struphuvudets bakre del och ibland stämbanden samt ingången till matstrupen. Det kan ge upphov till symtom i form av hosta, heshet, ökad slembildning och klumpkänsla i halsen. Inflammationen kan orsakas av flera olika Posterior laryngitis (PL) is defined as an inflammation involving the posterior part of the glottal region in conjunction with symptoms. The cause is multifactorial. The aims of the work presented in this thesis were to examine symptoms, physical signs, different aetiologies and health-related quality of life (HRQOL) in patients with PL and/or oesophageal dysmotility. In paper I, a group of pati
Three large-scale Echovirus (E) epidemics (E4,E16,E30), each differently associated to the acute development of diabetes related autoantibodies, have been documented in Cuba. The prevalence of islet cell autoantibodies was moderate during the E4 epidemic but high in the E16 and E30 epidemic. The aim of this study was to evaluate the effect of epidemic strains of echovirus on beta-cell lysis, beta-
Background: Primary hyperparathyroidism (pHPT) is a common disease that often remains undetected and causes severe disturbance especially in postmenopausal women. Therefore, national recommendations promoting early pHPT detection by plasma calcium (P-Ca) have been issued in Sweden. In this study we aimed to investigate variation of P-Ca analysis between physicians and health care centres (HCCs) in
Over a one-year study period (2003), we monitored total Hg (HgT) and methyl Hg (MeHg) at two sites in a Swedish forest stream located above (Site(ref)) and below a stretch of Hg-contaminated sediments (Site(Hg)). We also monitored HgT, MeHg, and ancillary water chemistry in peat water close to the stream and HgT in open field wet deposition. Despite the presence of historical Hg contaminants, dire
INTRODUCTION: Early identification of Alzheimer's disease (AD) is needed both for clinical trials and in clinical practice. In this study, we compared brief cognitive tests and cerebrospinal fluid (CSF) biomarkers in predicting conversion from mild cognitive impairment (MCI) to AD. METHODS: At a memory clinic, 133 patients with MCI were followed until development of dementia or until they had bee
We pursued the following three interconnected points: (1) there are unexplored opportunities for resilience scholars from different disciplines to cross-inspire and inform, (2) a systems perspective may enhance understanding of human resilience in health and social settings, and (3) resilience is often considered to be fractal, i.e., a phenomenon with recognizable or recurring features at a variet
