Popular Abstract in Swedish Ett poröst material är ett material med hålrum fyllda av gas eller vätska. Transport av molekyler genom ett poröst material beror på materialets struktur och har betydelse för områden som oljeutvinning, katalytisk avgasrening och blöjors uppsugningsförmåga. Porösa material vars struktur förändras beroende på vattenhalt är svåra att studera eftersom många av de traditioProton nuclear magnetic resonance (NMR) was used to study the self-diffusion of water in porous systems that respond to a change in water content in order to elucidate the porous structure and the properties of the confined water. In the carbohydrate systems cellulose fibers and starch granules, water is free to move throughout the porous objects, albeit with a rate reduced from the value of the

Binding of adenosine to the thermosensitive copolymer of N-isopropylacrylamide and 3-(acrylamido)aminophenylboronic acid (82:18, m ($) over bar (n)=47000 g center dot mol(-1)) was studied by equilibrium dialysis at 22 degrees C and 37 degrees C, in a 0.1 m glycine buffer containing 0.1 m NaCl at pH 9.2. The copolymer exhibited a the phase transition temperature (T-p) of 26.5 degrees C under the ab

The primary objective of this study was to systematically review and analyse epidemiological studies of the prevalence and incidence of atopic dermatitis (AD) during childhood and adulthood, focusing on data from the 21st century. A systematic search of PubMed, EMBASE and Google (manual search) was performed in June 2019, followed by data abstraction and study quality assessment (Newcastle–Ottawa

This paper sets out to create an implementation for fingerprint-based positioning using massive multiple-input multiple-output (MIMO) technology, by means of deep convolutional neural networks (CNN), and utilizing the wireless channel state information (CSI). Due to the sheer volume of computational requirements imposed by CNN processing, an accelerator-assisted design is well-suited to the task a

Persons with disabilities face substantial barriers that impede their integration and participation in social and economic activities. Households with disabled members may be vulnerable to poverty due to the extra cost of living with a disability. However, there exists a knowledge gap in the magnitude of the extra cost of disabilities in sub Saharan Africa. Using data from a nationally representat

PURPOSE: The aim of this study was to describe long-term adjustment to life with an ileal pouch-anal anastomosis after surgery for ulcerative colitis, to investigate the relationship of pouch function to adjustment, and to explore factors affecting quality of life.METHODS: A total of 369 patients treated between 1982 and 1993 were included in the study. Questionnaires designed to assess bowel (pou

The PREDICTS project—Projecting Responses of Ecological Diversity In Changing Terrestrial Systems (www.predicts.org.uk)—has collated from published studies a large, reasonably representative database of comparable samples of biodiversity from multiple sites that differ in the nature or intensity of human impacts relating to land use. We have used this evidence base to develop global and regional s

Since potential changes in the dynamics and mobility of drugs upon complexation for delivery may affect their ultimate efficacy, we have investigated the dynamics of two local anesthetic molecules, bupivacaine (BVC, C18H28N2O) and ropivacaine (RVC, C17H26N2O), in both their crystalline forms and complexed with water-soluble oligosaccharide 2-hydroxypropyl-β-cyclodextrin (HP-β-CD). The study was ca

The production of Wboson pairs in association with one jet in pp collisions at √s = 8 TeV is studied using data corresponding to an integrated luminosity of 20.3 fb-1collected by the ATLAS detector during 2012 at the CERN Large Hadron Collider. The cross section is measured in a fiducial phase-space region defined by the presence of exactly one electron and one muon, missing transverse momentum an

Employing a large number of antennas at the base station, massive MIMO significantly improves spectral efficiency and transmit power efficiency. On the other hand, massive MIMO also introduces unprecedented implementation challenges, especially in terms of processing and storage of large-size channel state information (CSI) matrices. Since on-chip memory is generally very expensive and has limited

År 1960 upptäcktes Cesium-137-aktivitet från atmosfäriska kärnvapenprovvid mätningar på lågaktivitets laboratoriet iLund. Denna händelse initierade mätningar av den svenska samiska befolkningen och iprodukter från ren som betar i de svenska fjällen. En semi-bärbarhelkropps detektor konstruerades med en detektionsgräns för 137Cs som var tillräckligt bra för att mäta människor med högakroppskoncentrIn 1960 Caesium-137 activity from atmospheric nuclear weapons test was dis-covered in measurements at the whole body gamma-ray counting laboratory inLund. This event initiated measurements of the Swedish Sami population, and inproducts from reindeer that bite lichens in the Swedish mountains. A semi-portable whole-body counter designed with a detection limit for 137 Cs at high radiation background

During the 20th century, a number of actors and institutions set out to develop taxonomies of the Swedish population. This thesis examines the most im­portant social classification system, the social group, which despite its great importance in administrative, scientific, commercial, political and media con­texts has received little attention in historical research. Invented by the Central Bureau

The immune cell component of the tumor microenvironment is an important modulator of tumor progression. In patients with breast cancer, tumor-infiltrating lymphocytes (TILs) and tertiary lymphoid structures (TLS) represent core aspects of anti-tumor immunity, both increasingly recognized for clinical relevance. In this study, we evaluated immune-related histology features using whole slide H&E

BACKGROUND: Medium vessel occlusions (MeVO) can be either isolated events (primary), or secondary to thrombus migration from a large vessel occlusion to a medium-sized vessel. Outcomes following endovascular thrombectomy (EVT) in the middle cerebral artery (MCA) may differ between primary and secondary MeVOs. This study aimed to assess the association between primary/secondary MeVOs and clinical o

This letter proposes a co-designed millimeter-wave (mm-wave) and sub-6GHz antenna system. The antenna system consists of four 28GHz mm-wave arrays with reconfigurable radiation patterns and two sub-6GHz antennas fed with two corner capacitive coupling elements (CCEs). Each corner CCE is formed by the connected ground planes of two mm-wave arrays in the shared-aperture configuration. The two CCEs a

Complex recombinant biomaterials that merge the self-assembling properties of different (poly)peptides provide a powerful tool for the achievement of specific structures, such as hydrogel networks, by tuning the thermodynamics and kinetics of the system through a tailored molecular design. In this work, elastin-like (EL) and silk-like (SL) polypeptides are combined to obtain a silk-elastin-like re

Objectives: To assess the potential impact on occupational health and work capacity for people exposed at work to increasing heat due to climate change. Design: A brief review of basic thermal physiology mechanisms, occupational heat exposure guidelines and heat
