Experimental investigation of water absorption and penetration in clay brick masonry under simulated uniform water spray exposure

In this study, we performed an experimental investigation of water absorption and penetration in clay brick masonry exposed to cyclic water spraying by employing a newly developed test setup. Several parameters, including brick absorption properties and different mortar joint profiles, were investigated. The specimens were exposed to a uniform water spray rate ranging between 1.7 and 3.8 l/m2/h, a

Distribution of under-5 deaths in the neonatal, postneonatal, and childhood periods : a multicountry analysis in 64 low- and middle-income countries

BACKGROUND: As under-5 mortality rates declined all over the world, the relative distribution of under-5 deaths during different periods of life changed. To provide information for policymakers to plan for multi-layer health strategies targeting child health, it is essential to quantify the distribution of under-5 deaths by age groups.METHODS: Using 245 Demographic and Health Surveys from 64 low-

Dietary intake of advanced glycation endproducts and risk of hepatobiliary cancers : a multinational cohort study

Advanced glycation endproducts (AGEs) may contribute to liver carcinogenesis because of their pro-inflammatory and pro-oxidative properties. Diet is a major source of AGEs, but there is sparse human evidence on the role of AGEs intake in liver cancer aetiology. We examined the association between dietary AGEs and the risk of hepatobiliary cancers in the European Prospective Investigation into Canc

Fighting microbial infections with force fields: Evaluating conformational ensembles of intrinsically disordered proteins

The main goal of this compilation thesis has been to investigate the conformational ensemble of the intrinsically disordered protein (IDP) histatin 5 by using a mixture of experimental and computational techniques including, but not limited to, small-angle X-ray scattering (SAXS), circular dichroism (CD) spectroscopy, atomistic molecular dynamics (MD) simulations, and coarse-grained Monte Carlo (M

Tissue response of radiation therapy assessed by electrical impedance spectroscopy (EIS) in subcutaneous tumours in rats.

Föreliggande undersökning syftar till att utvärdera möjligheten att använda bioimpedansspektrometri för att mäta tumör- och vävnadsrespons på strålterapi. Bioimpedansmätningar utförda med CythorLab ™ utrustade med en signalgenerator med en känd högutgångsimpedans och signalmätanordning som kan mäta spänningen som appliceras av generatorn. Styrenheten utlöser signalgeneratorn som genererar en MLS-sThe present investigation aims to evaluate the possibility of using bio-impedance spectrometry to measure tumour and tissue response to radiation therapy. Bio -impedance measurements performed with CythorLab™ equipped with a signal generator with a known high output impedance and signal measuring device able to measure the voltage applied by the generator. The control unit triggers the signal gene

Upscaling of multi-beam x-ray ptychography for efficient x-ray microscopy with high resolution and large field of view

Nondestructive imaging with both a large field of view and a high spatial resolution is crucial to understand complex materials and processes in science and technology. X-ray ptychography can provide highest spatial resolution but is limited in the field of view by the acquisition time and coherent flux at modern x-ray sources. By multi-beam ptychography, the sample can be imaged in parallel by se

Planar refractive lenses made of SiC for high intensity nanofocusing

We report on the manufacturing and testing of the first nanofocusing refractive lenses made of single-crystal silicon carbide. We introduce the fabrication process based on lithography, followed by deep isotropic etching. The lenses were characterized at the energy of 12 keV at the beamline P06 of the synchrotron radiation source PETRA III. A focal spot of 186 nm x 275 nm has been achieved with a

3D nano-tomography using coherent X-rays

X-rays allow to non-destructively investigate biological, chemical or physical processes at thenano-scale. Their high penetration depth in matter allows to investigate samples even in-side sample environments, which would be difficult with complementary methods such astransmission electron microscopy (TEM). The microscopy technique ptychography has beenestablished in X-ray imaging in recent years.X-rays allow to non-destructively investigate biological, chemical or physical processes at the nano-scale.

The spatiotemporal distribution of historical malaria cases in Sweden: a climatic perspective

BackgroundUnderstanding of the impacts of climatic variability on human health remains poor despite a possibly increasing burden of vector-borne diseases under global warming. Numerous socioeconomic variables make such studies challenging during the modern period while studies of climate–disease relationships in historical times are constrained by a lack of long datasets. Previous studies have ide

The Strong Screening Rule For SLOPE

Extracting relevant features from data sets where the number of observations n is much smaller then the number of predictors p is a major challenge in modern statistics. Sorted L-One Penalized Estimation (SLOPE)—a generalization of the lasso---is a promising method within this setting. Current numerical procedures for SLOPE, however, lack the efficiency that respective tools for the lasso enjoy, p

Patterns of pathologic lymph nodes in anal cancer : a PET-CT-based analysis with implications for radiotherapy treatment volumes

Background: This study investigates the patterns of PET-positive lymph nodes (LNs) in anal cancer. The aim was to provide information that could inform future anal cancer radiotherapy contouring guidelines. Methods: The baseline [18F]-FDG PET-CTs of 190 consecutive anal cancer patients were retrospectively assessed. LNs with a Deauville score (DS) of ≥3 were defined as PET-positive. Each PET-posit
