This study presents a novel approach for indirect integration of InAs nanowires on 2('') Si substrates. We have investigated and developed epitaxial growth of InAs nanowires on 2('') Si substrates via the introduction of a thin yet high-quality InAs epitaxial layer grown by metalorganic vapor phase epitaxy. We demonstrate well-aligned nanowire growth including precise position and diameter control
Human neutrophils are activated by the beta-galactoside-binding lectin galectin-3, provided that the cells are primed by in vivo extravasation or by in vitro preactivation with, for example, LPS. Removal of terminal sialic acid can change neutrophil functionality and responsiveness due to exposure of underlying glycoconjugate receptors or change in surface charge. Here, we investigated whether suc
Mikhlin's method for solving Laplace's equation in domains exterior to a number of closed contours is discussed with particular emphasis on the Dirichlet-Neutnann map. In the literature there already exit tyro computational modes for Mikhlin's method. Here a new mode is presented. The new mode is at least as stable as the previous modes. Furthermore, its computational complexity in the number of c
Background: Free and total human kallikrein 2 (hK2) might improve the discrimination between prostate cancer and benign prostatic hyperplasia. Concentrations of hK2 are 100-fold lower than concentrations of prostate-specific antigen (PSA); therefore, an hK2 assay must have a low detection limit and good specificity. Methods: PSA- and hK2-specific monoclonal antibodies were used in solid-phase, two
We have earlier shown that galectin-3, a lactose-binding mammalian lectin that is secreted from activated macrophages, basophils, and mast cells, induces activation of the NADPH oxidase in exudated but not in peripheral blood neutrophils (A. Karlsson, P. Follin, H. Leffler, and C. Dahlgren, Blood 91:3430-3438, 1998). The alteration in responsiveness occurring during extravasation correlated with m
We establish the local well-posedness for a new nonlinearly dispersive wave equation which has solutions that exist for indefinite times as well as solutions that blowup in finite time. We also derive an explosion criterion for the equation, and we give a sharp estimate of the existence time for solutions with smooth initial data.
We present a digital solution for the front-end electronics of high resolution calorimeters at future colliders. It is based on analogue signal compression, high speed A/D converters, a fully programmable pipeline and a digital signal processing (DSP) chain with local intelligence and system supervision. This digital solution is aimed at providing maximal front-end processing power by performing w
Packaging is becoming increasingly important from a marketing as well as logistics perspective, particularly for actors in consumer product supply chains. However, the role of packaging in creating or contributing to the competitive advantage of a company or a whole supply chain is still unexplored to a large extent. This is even the case in businesses where research has shown the benefits of cons
To reach its large computing needs, the ALICE experiment at CERN has developed its own middleware called AliEn, centralised and relying on pilot jobs. One of its strength is the automatic installation of the required packages. The Nordic countries have offered a distributed Tier-1 centre for the CERN experiments, where the job management should be done with the NorduGrid middleware ARC. We have de
Mechanisms that govern transport, accumulation and toxicity of persistent pollutants at interfaces in aquatic ecosystems are the foci of this thesis. Specific attention is paid to humic substances, their occurrence, composition, and role in exchange processes across interfaces. It was concluded that: Composition of humic substances in aquatic surface microlayers is different from that of the subsu
A recurrent issue and to a considerable extent also a major obstacle in contemporary theology of religions are various claims of "uniqueness". This article critically considers one particular aspect, i.e., the quest of the unique Jesus in New Testament scholarship and its implications for global interreligious dialogue. It is argued that the quest of the unique Jesus be abandoned since it is neith
This paper presents the characterization of forced cooling channels with three different shapes which are applied in traction motors mounted in Hybrid Vehicles (HEVs) or Zero Emission Vehicles (ZEVs). Generally, there are two different positions of forced cooling channels in electric motors. One way is by drilling holes or cutting cooling channels inside the housing, which is called indirect cooli
There are water vapour condensation and two-phase flow in plate heat exchangers when they are used as condensers. Water phase change and flow dynamics modelling is an important but complicated task due to large change in water physical/transport properties across the water liquid-vapour interface boundary. In particular, singular-link behaviour in governing equations is present due to the large st
This paper presents a new and practical simulation interface to design and analyze lower-limb prosthetic devices. The proposed tool simulates the gait of a lower limb amputee using a desired prosthetic device. It allows the analysis of simple passive devices or the testing of control algorithms for active prostheses. The results presented in this paper correspond to the use of this tool to test a
The following text addresses the ecological and cultural significance of the threats affecting the honey-bee, and which are becoming apparent through the unusual and sometimes drastic death rates of bee colonies. General research conducted on this problem largely agrees that the threats to bees are a syndrome that has a multifactorial nature and anthropogenic origin. In face of a plethora of relev
To fulfill increasing requirements within the manufacturing sector, highly flexible and adaptable automation systems are needed. It is desirable to have one integrated approach that stretches from the process planning phase, through the implementation phase and all the way to the phase for execution of the process control logics. One promising approach is to use the concepts of service-oriented ar
