Pilot studies of new concepts for water treatment

Two new membrane concepts have been piloted have been piloted in in recent years at Lund University in Sweden – namely (1) direct membrane filtration (DMF) and (2) water harvesting. Both concepts use submerged membranes as the established membrane bioreactor (MBR) concept but they exclude a biological treatment. This presentation will showcase the latest developments and experiences with these two

High-spin structure of normal-deformed bands in 84Zr

The reaction 58Ni(32S, α2p) at E lab= 135 MeV was used to populate high-spin states in 84Zr. The complete GAMMASPHERE and MICROBALL arrays were used to obtain clean γ- γ- γ line shapes to be analyzed by the Doppler shift attenuation method and to determine 27 lifetimes in the ground-state band and in two excited bands. Side-feeding times were also measured by comparing the line shapes gated with t

A story about Mobile Phone Radiation and Alzheimer's disease

Ett team av kliniska forskare i Lund, Sverige, fann att elektromagnetisk strålning, motsvarande den som används i mobil kommunikation, även vid låga SAR-effektvärden, gör att hes Fischer-344 råttor blodalbumin läcker genom blod-hjärnbarriären "BBB" in i hjärnvävnaden .Studierna utfördes vid Lunds universitet av:Neurokirurgerna: Leif Salford MD, PhD professor em„ Henrietta Nittby MD, PhD,Neuropatol

The success of membrane technology in the food industry is directly linked to the success of membranes in protein extraction. The first successful integration of membrane technology in the food industry was the extraction of proteins from whey – a byproduct of cheese production – which, due to its low solids content and high biological oxygen demand, posed a significant disposal challenge for the

Fourier analysis of cerebrospinal fluid flow velocities : MR imaging study

An interleaved pseudocinematographic FLASH (fast low-angle shot) sequence with additional pulsed gradients for flow encoding was used to quantify cerebrospinal fluid (CSF) flow velocities and CSF production. Flow-dependent phase information was obtained by subtracting two differently encoded phase images. The phase information in the resultant image was converted to flow velocity with a calibratio

New concepts for submerged membrane modules in water treatment

Submerged membrane modules either in flat or hollow fibre configuration have established themselves as a standard module for membrane bioreactors (MBRs) in municipal and industrial wastewater treatment. In recent years two new concepts using submerged membrane modules have been developed for (1) direct membrane filtration (DMF) for municipal wastewater treatment and for (2) storm and rain harvesti

Presenting Conclusions from Assessed Evidence

Applying evidence builds on the conclusions of the assessment of the evidence. The aim of the chapter is to describe a range of ways of summarising and visualising different types of evidence so that it can be used in various decision-making processes. Evidence can also be presented as part of evidence capture sheets, argument maps, mind maps, theories of change, Bayesian networks or evidence rest

The influence of AI and smart apps on tourist public transport use : applying mixed methods

The purpose of this research is to examine the roles of benefits and awareness of AI, as well as the usefulness and knowledge of smart apps in shaping tourist public transport use in South Korea, considering senior and younger population segments and gender. This research utilizes a mixed-methods approach (partial least squares structural equation modeling (PLS-SEM), multigroup analysis (MGA), fuz

Cumulative live birth rate after IVF : Trend over time and the impact of blastocyst culture and vitrification

STUDY QUESTION: Has cumulative live birth rate (CLBR) improved over time and which factors are associated with such an improvement? SUMMARY ANSWER: During an 11-year period, 2007-2017, CLBR per oocyte aspiration increased significantly, from 27.0% to 36.3%, in parallel with an increase in blastocyst transfer and cryopreservation by vitrification. WHAT IS KNOWN ALREADY: While it has been shown that

Direct Membrane Filtration-A new concept for municipal wastewater treatment

Direct Membrane Filtration (DMF) is a relatively new concept for the treatment of municipal wastewater. While the widely established membrane bioreactor (MBR) concept combines biological treatment with membrane separation, the DMF concept operates abiotic. The DMF concept is particularly suited treating municipal wastewater having only BOD and total phosphorous (Ptot) discharge demands. Furthermor

Potential of membrane processes in the concept of lignocellulose biorefineries

The pulp and paper industry is one of the key industrial sectors worldwide and is a cornerstone for conversion 10 toward a future bio-economy in particular as lignocellulosic bio-refineries. In this presentation, the potential of pressure-driven membrane processes – microfiltration, ultrafiltration and nanofiltration – in this conversion will be highlighted in three application studies related to

Cortical microvascular raspberries and ageing : an independent but not exclusive relationship

Introduction: Raspberries are cerebral microvascular formations of unknown origin, defined as three or more transversally sectioned vascular lumina surrounded by a common perivascular space. We have previously demonstrated an increased raspberry density in the cortex of patients with vascular dementia and cerebral atherosclerosis, while studies by other authors on overlapping and synonymously defi

Prolonged Sick Leave Before and After Diagnosis of Generalized Pustular Psoriasis : A Swedish Population-based Register Study

The aim of this study was to analyse sick leave in generalized pustular psoriasis, the most severe form of pustular psoriasis. Prolonged sick leave of >14 days was analysed for 502 patients with generalized pustular psoriasis compared with controls with psoriasis vulgaris and matched controls from the general population. Using data from the Swedish National Patient Register, and the Longitudinal i

Evaluation of intensity-modulated electron FLASH radiotherapy in a clinical setting using veterinary cases

Purpose: The increased normal tissue tolerance for FLASH radiotherapy (FLASH-RT), as compared to conventional radiotherapy, was first observed in ultra-high dose rate electron beams. Initial clinical trials in companion animals have revealed a high risk of developing osteoradionecrosis following high-dose single-fraction electron FLASH-RT, which may be related to inhomogeneities in the dose distri

Adaptation to climate change through dispersal and inherited timing in an avian migrant

Many organisms fail to adjust their phenology sufficiently to climate change. Studies have concentrated on adaptive responses within localities, but little is known about how latitudinal dispersal enhances evolutionary potential. Rapid adaptation is expected if dispersers from lower latitudes have improved synchrony to northern conditions, thereby gain fitness and introduce genotypes on which sele

The C-reactive protein Albumin ratio was not consistently associated with cardiovascular and all-cause mortality in two community-based cohorts of 70-year-olds

C-reactive protein (CRP)/Albumin ratio (CAR) seems to mirror disease severity and prognosis in several acute disorders particularly in elderly patients, which we aimed to study. As method we use a prospective study design; the Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS; n = 912, women 50%; mean age 70 years, baseline 2001 and 2004, median follow-up 15.0 years, end of fo

Internet-delivered cognitive behavioral therapy for adolescents with insomnia : Feasibility and preliminary efficacy

Background: Insomnia is common in adolescents. This study evaluated feasibility and preliminary efficacy of a six-week internet-delivered cognitive-behavioral therapy for insomnia (ICBT-I) in adolescents. Methods: In this uncontrolled pilot study, participants (n = 27, 78% female) completed assessments pre- and post intervention. Data on recruitment, adherence to treatment, treatment activity, sat
