Intermolecular hydrogen bonding in thick films of pyridine carboxylic acids (isonicotinic, picolinic and bi-isonicotinic acid) evaporated onto rutile TiO2(1 1 0) has been investigated with X-ray photoelectron spectroscopy and X-ray absorption spectroscopy. These molecules are shown to be strongly H-bonded in the condensed phase, and a surface core-level shift is observed due to the presence of non

Low surface concentrations of mass-selected clusters deposited under ultra high vacuum conditions on a well-characterized surface were studied with XPS. Analysis of monomers and dimers deposited at low temperature in a thick Xe buffer layer indicates the mobility and aggregation of the clusters in such a film. A stable average cluster size is reached at 53 K that is likely to be the same for all i

During the past one and a half decades ambient pressure x-ray photoelectron spectroscopy (APXPS) has grown to become a mature technique for the real-time investigation of both solid and liquid surfaces in the presence of a gas or vapour phase. APXPS has been or is being implemented at most major synchrotron radiation facilities and in quite a large number of home laboratories. While most APXPS ins

We have studied the adsorption of two silane compounds, (3-mercaptopropyl) trimethoxysilane (MPTMS) and n-propyltriethoxysilane (PTES), on a rutile TiO2(110) surface using angle dependent X-ray photoelectron spectroscopy. The observation of the S 2p line, in the case of MPTMS, and the C 1s line for both MPTMS and PTES confirms the adsorption of the molecules. For a dose of 122 Langmuirs of MPTMS w

When it comes to determining the jurisdictional reach of VAT two principles are used by the OECD, EU policy makers and scholars, namely, the origin principle and the destination principle. These principles can mean different things. One problem is that different constructions thereof can result in confusion in the communication between legal actors and, more importantly – in different legal outcom

We demonstrate a tool for identifying, prioritizing and evaluating vulnerabilities in software. The tool aims to improve security in products by making maintenance more efficient and robust. Software components and release versions are matched with vulnerability information from open resources. The results are visualized on several different levels, ranging from product portfolio and individual prWe demonstrate a tool for identifying, prioritizing and evaluating vulnerabilities in software.

This thesis comprises a study of the ethical thought of Iris Murdoch with special emphasis, as evidenced by the title, on how morality is intimately connected to self-improvement aiming at perfection and how the study of (literary) fiction has an important role to play in our strive towards bettering ourselves within the framework set by Murdoch’s moral philosophy.

Livestock production is important for local food security and as a source of income in sub-Saharan Africa. The human population of the region is expected to double by 2050, and at the same time climate change is predicted to negatively affect grazing resources vital to livestock. Therefore, it is essential to model the potential grazing output of sub-Saharan Africa in both present and future clima

Background Gestational diabetes (GDM) is a more common problem in India than in many other parts of the world but it is not known whether this is due to unique environmental factors or a unique genetic background. To address this question we examined whether the same genetic variants associated with GDM and Type 2 Diabetes (T2D) in Caucasians also were associated with GDM in North Indian women. M

En av de största utmaningarna i modern tid är att på ett hållbart sätt producera mat och andra varor för en ökande global befolkning, utan att utsätta mark- och vattenresurser för ytterligare belastning och därmed ha negativ inverkan på människors livskvalitet. Storskaligt jordbruk har genererat många fördelar för människan gällande matproduktion, men har även bidragit till många hållbarhetsutmaniA major challenge of our time is to sustainably produce food and other goods for a growing global population, without putting additional pressures on land and water resources and local people’s quality of life. Large-scale agriculture has brought many benefits to humanity in terms of food production but has also caused multiple sustainability challenges, including land and water degradation, defor

We present new coarse resolution (0.5° × 0.5°) vegetation height and vegetation-cover fraction data sets between 60° S and 60° N for use in climate models and ecological models. The data sets are derived from 2003–2009 measurements collected by the Geoscience Laser Altimeter System (GLAS) on the Ice, Cloud and land Elevation Satellite (ICESat), the only LiDAR instrument that provides close to glob

In the design of bridges, thermal loads are important to take into account since they can cause cracking if the structure or structural part is restrained from changing its size. Accurate thermal load values must therefore be used in bridge design, based on knowledge of the actual temperature distribution in the bridge. This paper presents the validation of a model for temperature simulation, to b

Objectives: We investigated the potential associations between cerebrospinal fluid (CSF) levels of total tau (T-tau) and phosphorylated tau (P-tau), short-term response to cholinesterase inhibitor (ChEI) treatment, longitudinal outcome and progression rates in Alzheimer’s disease (AD).Methods: The Swedish Alzheimer Treatment Study (SATS) is a prospective, observational, multicentre study to assess

Background: Few studies have focused on predictors of survival in patients with early-onset Alzheimer’s disease (EOAD) compared with late-onset Alzheimer’s disease (LOAD). We aimed to investigate the effect of genetic, sociodemographic, and clinical factors on mortality in the two groups.Methods: The Swedish Alzheimer Treatment Study (SATS) is a prospective, observational, multicenter study for lo

This study examines the interdependence between R&D resources, coopetitive performance and extent of cooperation in development- related standardization settings that involve network effects. Coopetitive performance is measured as the firm’s influence on the change process of standards. Cooperation is measured as the number of firm technology partners in influencing industry technology standar
