Substituted arylethanols can be coupled by using a readily available Ru catalyst in a fully deoxygenative manner to produce hydrocarbon chains in one step. Control experiments indicate that the first deoxygenation occurs through an aldol condensation, whereas the second occurs through a base-induced net decarbonylation. This double deoxygenation enables further development in the use of alcohols a

Peatlands are important carbon reserves in terrestrial ecosystems. The microtopography of a peatland area has a strong influence on its carbon balance, determining carbon fluxes at a range of spatial scales. These patterned surfaces are very sensitive to changing climatic conditions. There are open research questions concerning the stability, behaviour and transformation of these microstructures,

The interaction of CO with the Fe3O4(001)-(√2 × √2)R45° surface was studied using temperature-programmed desorption (TPD), scanning tunneling microscopy (STM), and X-ray photoelectron spectroscopy (XPS), the latter both under ultrahigh vacuum (UHV) conditions and in CO pressures up to 1 mbar. In general, the CO-Fe3O4 interaction is found to be weak. The strongest adsorption occurs at surface defec

This paper analyzes the Cutting and Breaking (C&B) events affecting the tangible aspects of the personal domain, that is to say the body and its parts. The study of the embodied Self, as the affected theme of C&B events, provides a unique opportunity to contribute to the understanding of the conceptualization of the personal domain, as well as providing an additional distinction between cu

Background: There are several scientific indications that increasing heat due to climate change is going to become the next big societal and scientific challenge. Climate change is recognized as a significant public health threat. However, there is a lack of research on its impacts on occupational safety and health. Aims and Objectives: The general aim of the research presented in this thesis was

Due to their potential for affecting the modulation of behaviour, effects of selective serotonin reuptake inhibitors (SSRIs) in the environment are particularly interesting regarding interspecies interactions and non-consumptive effects (NCEs) induced by predator cues in prey organisms. We evaluated the effects of sertraline (0.4, 40 ng/L, 40 µg/L) over 8 days on activity and habitat choice in the

Grammatical asymmetries in possessive constructions are overtly coded in about 18% of the world’s languages according to the World Atlas of Language Structures (Dryer & Haspelmath, 2013). What primarily motivates these grammatical asymmetries is controversial and has been at the crux of the “iconicity vs. frequency” debate (e.g. Croft, 2008; Haiman, 2008; Haspelmath, 2008). This paper contribu

In this work, the spatial extent of new particle formation (NPF) events and the relative probability of observing particles originating from different spatial origins around three rural sites in eastern China were investigated using the NanoMap method, using particle number size distribution (PNSD) data and air mass back trajectories. The length of the datasets used were 7, 1.5, and 3 years at rur

Chemotherapeutics are vital for treating brain tumors such as glioblastoma, an aggressive and prolific cancer predominantly treated with DNA alkylating agents. The efficacy of antiglioblastoma drugs, such as temozolomide, is limited by their rapid clearance and instability under normal physiological conditions. Both local and systemic polymer-based therapeutics have shown promise for treating many

Primary brain tumors are predominantly malignant gliomas. Grade IV astrocytomas (glioblastomas, GBM) are among the most deadly of all tumors; most patients will succumb to their disease within 2 years of diagnosis despite standard of care. The grim outlook for brain tumor patients indicates that novel precision therapeutic targets must be identified. Our hypothesis is that the cancer proteomes of

This article deals with the developments that followed the referendum in Iraqi Kurdistan conducted in 25/9/2017 and the major consequences of that referendum for Kurdish politics in Iraq and for the future of the Kurds in that country.

Background: When the Swedish version of Open Notes, an electronic health record (EHR) service that allows patients online access, was introduced in hospitals, primary care, and specialized care in 2012, psychiatric care was exempt. This was because psychiatric notes were considered too sensitive for patient access. However, as the first region in Sweden, Region Skåne added adult psychiatry to its
