INVESTIGATION OF THE DYNAMISM OF NANOSIZED SOA PARTICLE FORMATION IN INDOOR AIR BY A SCANNING MOBILITY PARTICLE SIZER AND PROTON-TRANSFER-REACTION MASS SPECTROMETRY

Investigation of the Dynamism of Nanosized SOA Particle Formation in Indoor Air by a Scanning Mobility Particle Sizer and Proton-Transfer-Reaction Mass Spectrometry

Paper Tray Terpenes are VOCs of particular importance, since they are emitted from a wide range of indoor sources and are considered to be precursors of Secondary Organic Aerosol (SOA) formation.It has been proven that SOA particles, especially nanosized ones, pose a threat to human health.In this research, experiments with the application of an en

Integrating Cytogenetics and Population Genomics: Allopatry and Neo-Sex Chromosomes May Have Shaped the Genetic Divergence in the Erythrinus erythrinus Species Complex (Teleostei, Characiformes)

Diversity found in Neotropical freshwater fish is remarkable.It can even hinder a proper delimitation of many species, with the wolf fish Erythrinus erythrinus (Teleostei, Characiformes) being a notable example.This nominal species shows remarkable intra-specific variation, with extensive karyotype diversity found among populations in terms of diff

Development of a small autonomous pipe inspection robot (Modularization of hardware using the technique of wooden mosaic work)

Since 1965, the number of cities constructing and operating sewerage systems had been on the rise, with waterway overhaul now prevalent in many parts of Japan.However, as the number of facilities under management has increased, their decrepitness has become obvious.The average service life of sewer pipe has been determined to be 50 years, but in re

Insufficient recruitment and premature discontinuation of clinical trials in Switzerland: qualitative study with trialists and other stakeholders

AIMS OF THE STUDY Premature discontinuation occurs in about 25% of randomised clinical trials in Switzerland; it mainly affects investigator-initiated trials and is mostly due to problems with recruitment of patients.The aim of this study was to qualitatively investigate reasons for trial discontinuation due to poor patient recruitment and suggesti
