Development of a sample preparation method for the GC-analysis of e-cigarette refill liquids

limit the transfer of the matrix to the column. The headspace temperature was chosen in  order to obtain an optimal transfer of the target components to the headspace with minimal transfer of the matrix ...

A simple dilute-and-shoot method for screening and simultaneous quantification of nicotine and alkaloid impurities in electronic cigarette refills (e-liquids) by UHPLC-DAD

excluded. In addition, small changes to the column temperature, pH and molar concentration of the mobile phase buffer were deliberately introduced in order to assess the robustness of the method. Only ...

European all-cause excess and influenza-attributable mortality in the 2017/18 season: should the burden of influenza B be reconsidered?

using the FluMOMO algorithm, incorporating influenza activity based on clinical and virological surveillance data, and adjusting for extreme temperatures. Results Excess mortality was mainly attributable ...

Occurrence and identification of spore-forming bacteria in skim-milk powders

representative of the various tests. Of the isolates identified, 68% were  Bacillus licheniformis, a facultative anaerobe that can survive and grow at mesophilic and thermophilic temperatures, making it difficult ...

Temperature-related changes in airborne allergenic pollen abundance and seasonality across the northern hemisphere: a retrospective data analysis

Ongoing climate change might, through rising temperatures, alter allergenic pollen biology across the northern hemisphere. We aimed to analyse trends in pollen seasonality and pollen load and to establish ...

Sensitivity of African swine fever virus (ASFV) to heat, alkalinity and peroxide treatment in presence or absence of porcine plasma.

Fever Virus Animals Antacids Hot Temperature Hydrogen Peroxide plasma Swine Virus Inactivation Abstract: African swine fever virus (ASFV) is a highly resistant viraemic virus with devastating ...

Relationships between aeroallergen levels and hospital admissions for asthma in the Brussels-Capital Region: a daily time series analysis.

holidays, mean temperature and relative humidity. Effect modification by age and air pollution (PM, NO, O) was tested. RESULTS: A significant increase in asthma hospitalizations was observed for an ...

Short-term effects of nitrogen dioxide on hospital admissions for cardiovascular disease in Wallonia, Belgium.

cardiovascular health in Wallonia for the period 2008-2011. This study also seeks to evaluate the effects of age, gender, season and temperature on this association. The effect of the delay between exposure and ...

Comparative long-term trend analysis of daily weather conditions with daily pollen concentrations in Brussels, Belgium.

Hendrickx Source: Int J Biometeorol, Volume 62, Issue 3, Number 491 (2018) Keywords: Allergy Climate change Meteorological factors pollen Abstract: A clear rise in seasonal and annual temperatures, a gradual ...

Heat and health in Antwerp under climate change: Projected impacts and implications for prevention.

summer daily temperatures for two periods, one in the near (2026-2045) and one in the far future (2081-2100), under the Representative Concentration Pathway (RCP) 8.5. We then analysed the relationship ...
