Membrane spacers are an essential part of spiral wound modules and can significantly influence the mass transfer performance and pressure drop in the modules. To develop further understanding of the importance of spacer selection, the performance of two configurations of parallel spacers for ultrafiltration using Dextan T40 was analysed in this study using lab-scale experiments and CFD simulation

The properties of laser wakefield accelerated electrons in supersonic gas flows of hydrogen and helium are investigated. At identical backing pressure, we find that electron beams emerging from helium show large variations in their spectral and spatial distributions, whereas electron beams accelerated in hydrogen plasmas show a higher degree of reproducibility. In an experimental investigation of

The Paper and Plastics Education and Research Insitute at the University of North Florida and NPTA have taken an initiative to adopt and implement the papiNet standards for supply chain standardization and integration. papiNet can be described as a global standard for the paper and forest industries. The companies, which want to adopt papiNet, are required to follow the standards developed by the

In recent years, great progress has been made on the problem of 3D scene reconstruction using depth sensors. On a large scale, these reconstructions look impressive, but often many fine details are lacking due to limitations in the sensor resolution. In this paper we combine two well-known principles for recovery of 3D models, namely fusion of depth images with photometric stereo to enhance the de

OBJECTIVE: To describe, explain and give practical suggestions regarding important principles and key methodological challenges in the study design, statistical analysis, and reporting of results from in vivo studies.CONCLUSIONS: Pre-specifying endpoints and analysis, recognizing the common underlying assumption of statistically independent observations, performing sample size calculations, and ad

In humanoid robotics, the recognition and synthesis of parametric movements plays an extraordinary role for robot human interaction. Such a parametric movement is a movement of a particular type (semantic), for example, similar pointing movements performed at different table-top positions. For understanding the whole meaning of a movement of a human, the recognition of its type, likewise its param

Contrary to what practice suggests, social media platforms may not be an appropriate forum for communicating with civil society about sustainability issues such as climate change. Misinformation campaigns are distorting the line between fact and falsity on social media platforms, and there has been a profound shift in the way that social media users consume and interact with information. These con

Studies from our and other laboratories have over the last 2 years implicated the existence of multipotent progenitors (MPPs) with combined granulocyte-macrophage, B cell, and T cell potential, but little or no megakaryocyte-erythroid (MkE) potential in the adult bone marrow Lineage (-)SCA-1 +KIT+ (LSK) compartment of multipotent stem and progenitor cells. The evidence for the existence of LSKCD34

We will consider a vector-valued Sturm-Liouville equation of the form R[U]:=-(PU')(')+QU=lambdaWU, xis an element of[0,b), with P-1, W, Qis an element ofL(loc)(1)([0,b))(mxm) being Hermitian and under some additional conditions on P-1 and W. We give an elementary deduction of the leading order term asymptotics for the Titchmarsh-Weyl M-function corresponding to this equation. In the special case o

In an investigation by the Swedish Cancer Society, the present status, critical issues and future aspects and potentials were described by an expert group for each of nine major areas of radiation therapy research, This report deals with medical imaging for improved medical diagnosis including tumour detection, staging and characterization, treatment planning, guiding and verification, evaluation

Popular Abstract in Swedish I denna avhandling behandlas två delvis överlappande teman; inversa problem av tomografisk karaktär samt snabba och noggranna metoder för applicering av faltningsoperatorer. Inom det första temat så studeras det inversa problemet inom Dopplertomografi och för detta ändamål så introduceras Dopplermomenttransformen. Genom att undersöka egenskaperna hos denna transform såThere are two, partially interlaced, themes treated in this thesis; inverse problems of tomographic type and fast and accurate methods for the application of convolution operators. Regarding the first theme, the inverse problem of Doppler tomography is considered and the Doppler moment transform is introduced for that purpose. By investigating the properties of the transform, we prove results reg

V/P(SPECT) has the potential to become a first hand tool for diagnosis of pulmonary embolism based on standardized technology and new holistic interpretation criteria. Pretest probability helps clinicians choose the most appropriate objective test for diagnosis or exclusion of PE. Interpretation should also take into account all ventilation and perfusion patterns allowing diagnosis of other cardio
