Allergic reactivity for different dilutions of eugenol in repeated open application test and patch testing

Background: Eugenol is a known contact sensitiser included in fragrance mix I. Objective: To assess the allergic reactivity to eugenol in different concentrations using patch test as well as repeated open application test (ROAT). Methods: Overall 67 subjects from 6 European dermatology clinics participated in the study. The ROAT was performed for 21 days twice a day, applying 3 dilutions of eugeno

Nanoplastics released from daily used silicone and latex products during mechanical breakdown

Waste of polymer products, especially plastics, in nature has become a problem that caught the awareness of the general public during the last decade. The macro- and micro polymers in nature will be broken down by naturally occurring events such as mechanical wear and ultra-violet (UV) radiation which will result in the generation of polymeric particles in the nano-size range. We have recently sho

Groundwater Vulnerability to Nitrate Contamination from Fertilizers Using Modified DRASTIC Frameworks

Vulnerability maps of groundwater provide an efficient means of identifying environmental trends and prioritizing regions for prevention plans. The GIS-based DRASTIC method, however, does not consider the impact of contamination, so there is a need to modify it according to the specifics of the region and its contamination load. The aim of this study is to investigate a suitable DRASTIC modificati

Ostädade väckelser : modernitetens förtrupper

Berättelsen om hur det moderna Sverige växte fram har länge varit förenklad. Övergången från ett förmodernt, patriarkalt samhälle till ett modernt och demokratiskt beskrivs gärna som medelklassens och centralmaktens förtjänst. Men något som ofta har utelämnats är de religiösa väckelsernas bidrag särskilt de extatiska och mer provocerande rörelserna.I denna antologi ger fjorton forskare från olika

Dynamic Community Detection for Brain Functional Networks During Music Listening With Block Component Analysis

The human brain can be described as a complex network of functional connections between distinct regions, referred to as the brain functional network. Recent studies show that the functional network is a dynamic process and its community structure evolves with time during continuous task performance. Consequently, it is important for the understanding of the human brain to develop dynamic communit

Orbital and sub-orbital space tourism : motivation, constraint and artificial intelligence

Purpose: There is limited research on the behavior of different categories of space tourists as identified by different types of space tourism. To address this deficiency, the purpose of this study is to examine what factors make consumers participate in orbital and/or suborbital space tourism, along with three dimensions of motivation, constraint and artificial intelligence. To achieve this study

Machine Learning Based Digital Pre-Distortion in Massive MIMO Systems : Complexity-Performance Trade-offs

In this paper, we study the trade-off between complexity and performance in massive MIMO systems with neural-network based digital pre-distortion (NN-DPD) blocks at the base station. In particular, we consider a multi-user massive MIMO system with per-antenna NN-DPDs, each with an adjustable NN architecture in terms of the size and the number of NN hidden layers. We first analyze the system perfor

The course of health-related quality of life after the diagnosis of childhood cancer : a national cohort study

BACKGROUND: Comprehensive insight in the longitudinal development of health-related quality of life (HRQOL) after childhood cancer diagnosis could improve quality of care. Thus, we aimed to study the course and biopsychosocial determinants of HRQOL in a unique national cohort of children with cancer.METHODS: HRQOL of 2154 children with cancer was longitudinally reported (median: 3 reports) between

Self-Heating in Gate-All-Around Vertical III-V InAs/InGaAs MOSFETs

We investigate self-heating in vertical, gate-all-around III-V InAs/InGaAs nanowire MOSFETs using pulsed IV measurements at various temperatures. Low temperature measurements reveal a negative output conductance indicating self-heating in the transistor. Under pulsed measurements, an increase in drain current (15%) and transconductance (30%) are observed at room temperature, with values influenced

Territorial mimetics and room types : The spatial development of Swedish district courthouses 1970-2020

In this article I investigate the spatial development of Swedish district courthouses and their different room types from 1970 to 2020, with attention to the specificities and commonalities with other building types. How have spatial form and use travelled between building types during this period, and how has this contributed to the recent, quite radical developments and transformation of the cou

MULTIDISCIPLINARY ASSESSMENT OF A YEAR 2035 TURBOFAN PROPULSION SYSTEM

A conceptual design of a year 2035 turbofan is developed and integrated onto a year 2035 aircraft model. The mission performance is evaluated for CO2, noise and NOx and is compared with a notional XWB/A350-model. An OGV heat exchanger is then studied rejecting heat from an electric generator, and its top-level performance is evaluated. The fan, the booster and the low-pressure turbine of the propu
