The cationic photopolymerization of trimethylolpropane tripropenyl ether (TPE), initiated by a diaryl iodonium salt, has been investigated. The influence of the presence of different alcoholic additives on the rates of photopolymerization and on the properties of the networks obtained has been studied. New 1-propenyl ethers (trimethylolpropane dipropenyl ether (DPE) and its acetyl ester) were synt

A kinetic investigation of the photoinitiated cationic copolymerization of 1-propenyl ethers with vinyl ethers monomers was performed by using FT-IR and 1H-NMR analysis. FT-IR results, obtained in bulk, indicate a higher reactivity of the vinyl ether with respect to the 1-propenyl ether double bond. 1H-NMR analysis, in CDCl3 solution, confirms these results which agree with the literature data con

Thiol-ene photocurable systems based on a trifunctional thiol [trimethylolpropane tris-(3-mercaptopropanoate)] and two different multifunctional allyl ethers (trimethylolpropane triallyl ether and Boltorn U2, an allyl functional dendritic polyester) were examined. To these systems, small amounts (

Despite profound progress made in reducing neonatal mortality, it remains one of the major global health challenges. In 2019, the World Health Organization estimated that 2.4 million neonatal deaths occurred, accounting for over 45 percent of under-5 deaths worldwide. Most of these neonatal mortalities occur in low-and middle-income (LMIC) with East African countries of Kenya, Uganda and Tanzania

Characteristics of polyol mercaptoalkanoates, polyol allyl ethers and coatings produced thereof are reported. The viscosities of examined thiols are in the range of 110-410 mPas (23 °C) and the density of functional groups 4-8 mmol/g. The corresponding data for the studied polyol allyl ethers are 3-240 mPas (23 °C) and 7.5-13.3 mmol/g, respectively. Formulations of these components were made and p

Alla svenska lärare har enligt skollagen ett dubbelt uppdrag, kunskapsuppdraget och demokratiuppdraget. Demokratiuppdraget uppfattas som problematiskt av utvärderande myndigheter, lärare och skolans huvudmän. Alla gymnasielärare i svenska ska enligt senaste läroplanen GY11 explicit arbete med retorik. Finns det retoriska övningar som kan integrera såväl litteratur- och språkundervisning med demokr

We analyzed the impacts of drought severity on a variety of sectors in a topographically complex basin (the upper Aragón basin 2181 km2) in the Central Spanish Pyrenees. Using diverse data sources including meteorological and hydrological observations, remote sensing and tree rings, we analyze the possible hydrological implications of drought occurrence and severity on water availability in variou

Background Mycobacterium tuberculosis (TB) is the deadliest disease that claims millions of deaths globally. Ethiopia is among the countries heavily hit by the disaster. Despite the effective directly observed treatment and TB infection control (TBIC) measures provided by the world health organization (WHO), the rate of new cases increased daily throughout the country. Healthcare workers (HCWs) ar

The climate-vegetation coupling exerts a strong control on terrestrial carbon budgets and will affect the future evolution of global climate under continued anthropogenic forcing. Nonetheless, the effects of climatic conditions on such coupling at specific times in the growing season remain poorly understood. We quantify the climate-vegetation coupling in Europe over 1982–2014 at multiple spatial

Background: Integrated community case management (CCM) has led to reductions in child mortality in Malawi resulting from illnesses such as malaria, pneumonia, and diarrhea. However, adherence to CCM guidelines is often poor, potentially leading to inappropriate clinical decisions and poor outcomes. We determined the impact of an e-CCM app on the referral, reconsultation, and hospitalization rates

MOTIVATION: Gene expression-based multiclass prediction, such as tumor subtyping, is a non-trivial bioinformatic problem. Most classifier methods operate by comparing expression levels relative to other samples. Methods that base predictions on the expression pattern within a sample have been proposed as an alternative. As these methods are invariant to the cohort composition and can be applied to

A search for new phenomena is presented in final states with two leptons and one or no b-tagged jets. The event selection requires the two leptons to have opposite charge, the same flavor (electrons or muons), and a large invariant mass. The analysis is based on the full run-2 proton-proton collision dataset recorded at a center-of-mass energy of s=13 TeV by the ATLAS experiment at the LHC, corres

PD-L1 expression assessed by immunohistochemical staining is used for the selection of immunotherapy in non-small cell lung cancer (NSCLC). Appropriate validation of PD-L1 expression in cytology specimens is important as cytology is often the only diagnostic material in NSCLC. In a previous study comprising two different cohorts of paired biopsies and cytological specimens, we found a fairly good

Objective:The objective of this scoping review is to identify and map subjective instruments that have been developed for children and adolescents with cerebral palsy from birth to 18 years to measure physical activity and sedentary behavior.Introduction:Children and adolescents with cerebral palsy often do not meet the recommended levels of physical activity, even though regular physical activity

Swedish coalition politics is markedly influenced both by a historically strong emphasis on near-unidimensional political conflict along the left-right economic dimension, the once-dominant position of the Social Democrats, and a negative parliamentarism system. These factors have contributed to most governments formed during the post-World War Two period comprising a minority of seats in parliame

BACKGROUND: Positive margins after breast-conserving surgery (BCS) and subsequent second surgery are associated with increased costs and patient discomfort. The aim of this study was to develop a prediction model for positive margins based on risk factors available before surgery. METHODS: Patients undergoing BCS for in situ or invasive cancer between 2015 and 2016 at site A formed a development c

Since 2009 initiatives that were selected for the roadmap of the European Strategy Forum on Research Infrastructures started working to build research infrastructures for a wide range of research disciplines. An important result of the strategic discussions was that distributed infrastructure scenarios were now seen as “complex research facilities” in addition to, for example traditional centralis

This review aims to provide a comprehensive overview of the in vitro, animal, and clinical studies with the bacterial strain Lactiplantibacillus plantarum 299v (L. plantarum 299v; formerly named Lactobacillus plantarum 299v) published up until June 30, 2020. L. plantarum 299v is the most documented L. plantarum strain in the world, described in over 170 scientific publications out of which more th
