IntroductionWithin the concept of waste water treatment the opportunity of integrating pervaporation has been widely recognised. Applying pervaporation, generally two different process designs can be applied – vacuum and sweep gas pervaporation. Previous research focused primarily exclusive on one of this process designs. In this study the benchmarks of vacuum and sweep gas pervaporation are de
Over the years several models have been developed to describe hydrophobic pervaporation. The different approaches can be generally classified as process-orientated or membrane-orientated. Among these models the resistance-in-series model (RSM) has a unique position since it combines process conditions with membrane parameters. The aim of this work is to demonstrate the extension of the RSM to c
In this paper the feasibility of combining pervaporation with conventional processes such as adsorption and steam stripping in a hybrid process to recover phenol from waste water is analysed taking technical and economical aspects into account. Compared to stand alone units it is found that hybrid processes based on pervaporation and conventional units can be an economic alternative for the meeti
An generalised engineering approach based on the analogy between mass and heat transfer is proposed to benchmark the shell-side mass transfer coefficient for axial flow in hollow fibre modules from low to moderate packing densities. The trends obtained by this approach are similar to those of correlations found in the literature and differences between the approaches are discussed. Furthermore,
The resistance-in-series model, used to describe the mass transfer through a membrane in pervaporation for binary systems, has been extended to include ternary and multi-component mixtures of different organic and inorganic compounds in aqueous solutions. The new model was used in a simulation including the membrane characteristics and the geometry of the pervaporation. Thus, the influence of proc
Genome wide association studies (GWAS) have mapped multiple independent cancer susceptibility loci to chr5p15.33. Here, we show that fine-mapping of pancreatic and testicular cancer GWAS within one of these loci (Region 2 in CLPTM1L) focuses the signal to nine highly correlated SNPs. Of these, rs36115365-C associated with increased pancreatic and testicular but decreased lung cancer and melanoma r
From 2012 to 2016 the drug industry donated over £57m (€65m; $73m) to UK patient organisations, with the annual sum more than doubling over the period. The funding benefited a small number of organisations and activities related to research and public involvement. The industry gave priority to commercially high profile conditions. Industry payment disclosures had limited transparency
Background: Deep learning convolutional neural networks (CNN) may facilitate melanoma detection, but data comparing a CNN's diagnostic performance to larger groups of dermatologists are lacking.Methods: Google's Inception v4 CNN architecture was trained and validated using dermoscopic images and corresponding diagnoses. In a comparative cross-sectional reader study a 100-image test-set was used (l
Meniscectomy is recognized as an important risk factor for the development of knee osteoarthritis (OA), a disease that traditionally has been considered as a simple "wear and tear" phenomenon. However, despite numerous reports, little evidence has been presented that a limited meniscal resection, compared with a more extensive resection, reduces the risk of OA by preserving meniscal function. Why?
OBJECTIVES: To compare patient reported outcomes from before surgery to 52 weeks after surgery between individuals undergoing arthroscopic partial meniscectomy for traumatic meniscal tears and those for degenerative meniscal tears.DESIGN: Comparative prospective cohort study.SETTING: Four public orthopaedic departments in the Region of Southern Denmark. Participants were recruited between 1 Februa
