A model for the adsorption of colloidal particles on a planar surface is analyzed by using a thermodynamic chemical equilibrium model and Monte Carlo simulations. Central to this investigation are that (i) particles and surface are considered to be of the same material and (ii) the particle-surface and particle-particle interactions are related using the Derjaguin approximation using a surface-sur
A study of biospecific interactions between lectins and glycoproteins using a quartz crystal microbalance biosensor with dissipation monitoring (QCM-D) was reported. Four lectins were covalently immobilised on the thiol-modified gold electrode of the QCM chips in order to obtain sensing surfaces. The frequency shift served as analytical signal and the dissipation shift provided additional informat
This text is an inquiry into how the international community is understood in and through international law. My prism for this inquiry shall be the principle of proportionality in international humanitarian law, relating expected civilian losses to anticipated military advantage. To properly understand proportionality, I have to revert to the structure of analogical thinking in the thomistic tradi
A discussion on the relationship between the church and the manor, the socalled westwork and the socalled royal palace at Dalby. The palace is interpreted as a monastery and the westwork as a "Galilaea", both from the 12th C.
Analytical sociology is a methodological strategy aimed at refining theoretically informed empirical social research. Given the central assumption that the role of sociology is to explain macro level phenomena, analytical sociology makes pragmatic use of abstract models of social action and interaction, such as the DBO-model. The realization that it is not a philosophy or a psychology, nor a unive
Each year around 8% of Swedish manufacturing firms leave an industry. Of the exit routes available, the least likely is firm closure. Firms are more likely to merge, become acquired or switch to a new industry. We investigate the importance of a range of firm and industry characteristics for the exit decision of Swedish firms from 1980–1996. From our analysis two patterns are evident. First, firms
Patients with a clinical picture of acute ischemic stroke are a heterogeneous group. The aim of this study was to evaluate the added utility of CT perfusion (CTP) and CT angiography (CTA) in the workup of three different categories of acute ischemic stroke patients. Fifty patients (61 +/- 05 years old) were included in this retrospective analysis. Twenty-nine patients had transient ischemic attack
This paper presents a method designed to identify underlying causes leading to industrial accidents. The method developed intends to facilitate the learning process from accidents by identifying possible causes related to the accidents that were not directly stated in an accident report, but that can be deduced following the description of the event, in particular with regard to the quality of the
This report is a literature review about sustainability and sustainable development in general and in an urban context. It focuses on theoretical issues and debates in scientific literature and aims at analyzing the different dimension of sustainability, namely social, ecological and economic sustainability. There are different conflicts between those dimensions of sustainability. Furthermore, the
Todorov´s distinction between theoretical genres and historical genres are logically analyzed, the first being classes, the second cultural, social facts. The theoretical genres cannot, according to Todorov, be falsified or verified. This is on account of the rule saying that the language of object and the metalanguage must not be mixed. But this mixing is always present in ordinary language, in l
This study investigates the relationship between student influence and academic self-efficacy in a sample of 275 students in two Master’s programmes in Engineering. Students in only one of the programmes studied according to problem-based learning (PBL). Results indicate that students choosing strategies to influence course content or structure, through course evaluation and recommending changes t

Homogeneous large-area graphene monolayers were successfully prepared ex situ on 6H-SiC(0001). The samples have been studied systematically and the results are compared with those from a sample cut from the same wafer and prepared by in situ heating. The formation of smaller graphene flakes was found on the in situ prepared sample, which is in line with earlier observations. Distinctly different r
A new version of the stream cipher Grain-128 is proposed. The new version, Grain-128a, is strengthened against all known attacks and observations on the original Grain-128, and has built-in support for optional authentication. The changes are modest, keeping the basic structure of Grain-128. This gives a high confidence in Grain-128a and allows for easy updating of existing implementations.
Background: Intracerebral infections after deep brain stimulation (DBS) are rare. The published material is limited to 2 case reports. A review of 20 publications of 3,818 patients focusing on complications of DBS did not reveal one single case. For that reason, we decided to present our own experience of 4 patients with this complication. Objectives: To analyze and present our material regarding
