Several studies of meteorites show that a large disruption of an asteroid occurred ca. 470 Ma in our solar system's asteroid belt. As a consequence, a large number of meteorite impacts occurred on Earth during the following few million years. The finding and characterization, for the first time, of planar deformation features in quartz grains from rocks collected at the Middle Ordovician Hummeln s
By using a Swern oxidation-epimerization-reduction sequence it is possible to selectively epimerize any position in isopropylidene-protected xylopyranosides, thus forming arabinosides, ribosides, and lyxosides. The driving force for epimerization of position 3 (xylo to ribo) is the release of ring strain by going from a 1,2-trans-acetal to a 1,2-cis-acetal.
Background: Ghrelin, an endogenous ligand for the growth hormone secretagogue receptor (GHSR), has two major functions: the stimulation of the growth hormone production and the stimulation of food intake. Accumulating evidence also indicates a role of ghrelin in cancer development. Methods: We conducted a case-control study to examine the association of common genetic variants in the genes coding
Sedan slutet av 1980-talet då Lagen om målsägandebiträde (1988:609) introducerades har svenska sexualbrottsoffer haft rätt till ett särskilt juridiskt biträde i form av det statligt finansierade målsägandebiträdet. Den bakomliggande idén till lagens införande var att kvinnor som utsatts för sexuella övergrepp är i behov av extra stöd och hjälp genom det straffrättsliga förfarandet, särskilt under Since the late 1980s when the Counsel for Injured Party Act (1988:609) was introduced, Swedish victims of sexual assault have had the right to a special legal counsel in the form of a government funded counsel for injured party. The underlying idea behind the Act was that sexually assaulted women are in need of extra support and assistance through the legal proceedings, especially during the preli
Background: The identification of novel genes by high-throughput studies of complex diseases is complicated by the large number of potential genes. However, since disease-associated genes tend to interact, one solution is to arrange them in modules based on co-expression data and known gene interactions. The hypothesis of this study was that such a module could be a) found and validated in allergi
In AIDS vaccine development the pendulum has swung towards a renewed emphasis on the potential role for neutralizing antibodies in a successful global vaccine. It is recognized that vaccine-induced antibody performance, as assessed in the available neutralization assays, may well serve as a "gatekeeper" for HIV-1 subunit vaccine prioritization and advancement. As a result, development of a standar
A search for neutral Higgs bosons decaying to pairs of tau leptons with the ATLAS detector at the LHC is presented. The analysis is based on proton-proton collisions at a center-of-mass energy of 7 TeV, recorded in 2010 and corresponding to an integrated luminosity of 36 pb(-1). After signal selection, 276 events are observed in this data sample. The observed number of events is consistent with th
Background: In European countries, knowledge about availability and utilization of support for informal caregivers caring for older persons (>= 65 years) with dementia (PwD) is lacking. To be able to evaluate and develop the dementia support system for informal caregivers to PwD, a survey of European support systems and professionals involved is needed. The aim of this study was to explore support
Many studies have tried to explain the stock market value premium identified by Fama and French and Rosenberg, Reid and Lanstein. To the proponents of conventional asset pricing theory the value premium, measured by HmL (high book-to-market minus low book-to-market), is a bit of a dilemma. This is due to that the value of growth stocks depend more on business cycles than on value stocks, whose val
The 'rule of law crises' in Hungary and Poland have shown weaknesses in the European Union’s system of enforcing the values enshrined in Article 2 TEU after accession. Especially Article 7 TEU as well as the other enforcement procedures have proven to be incapable of forcing Member States back into compliance with the values enshrined in Article 2 TEU so far. However, this thesis contests
The study of home has historically been approached by numerous academic disciplines within the social sciences and humanities. However, increased international mobility and forced migration due to conflict in recent years has produced a renewed interest to understand the ways we conceptualize and (re)create home in foreign places. The present research aims to produce a theoretical framework that a
Most of classic psychedelic literature indicate its potential benefit to society and the environment during a time of rapid environmental degradation and climate change– hinting its potential role to sustainability and socio-ecological transformation. There is virtually no study drawing the explicit interlinkages of classic psychedelic research to sustainability science but it is observed that the
Ecological rehabilitation projects - as a form of reforestation interventions - are increasing worldwide and present an opportunity for climate change mitigation and supporting local livelihoods. Implemented in post-conflict situations, they are increasingly promoted as solutions for peace. Aiming at understanding their contributions to sustainability and peacebuilding, I examine proposed rehabili
Even as the public awareness and concern about climate change are increasing, and the younger generations are urging for political action, support for more costly and ambitious mitigation policies is not given. The low-cost hypothesis theory provides an explanation for why our concern about climate change fails to translate into supporting policies when the personal cost is high. However, research
Adapting to climate change impacts is crucial as changes due to climate change are already locked in and will occur independently of reductions of greenhouse gas emissions. Recent studies in climate change adaptation literature have cited that social learning is beneficial for increasing adaptive capacity. The capacity for social learning is governed by the degree of flexibility of the institution
The Brundtland report envisioned three sustainable dimensions for development: economic growth, ecological balance, and social inclusion with the aim to incorporate these dimensions into local, national, and global plans for sustainable development. In recent years, discussions about our society’s competitiveness and whether the three dimensions of sustainable development include all aspects of ou
This thesis explores how early-stage startup founders use their professional networks to acquire equity investment from venture capitalists and business angels. Through qualitative interviews with founders across various industries, the research reveals essential networking practices that lead to successful fundraising efforts. The study highlights how building trust and credibility with network c
