Finnish university physics teachers' experiences of transferring to online teaching due to COVID-19 pandemic.

Unlabelled: The COVID-19 pandemic arguably caused the most rapid and extensive educational reform ever witnessed. This article addresses the challenges, possibilities, and consequences that the pandemic has set for Finnish physics university teachers. The data were gathered with a literature-based online survey consisting of Likert scale claims and open-ended questions related to the following themes: the use of technology, interaction, learning and evaluation, experimental working, and the future.

Exposure to electronic media was negatively associated with speech and language development at 18 and 24 months.

Aim: This study evaluated early speech and language development at 18 and 24 months, and associated factors, based on parental reports.

Method: We followed up the CHILD-SLEEP birth cohort of 1667 Finnish-speaking families, who were randomly recruited in 2011-2013 during routine visits to maternity clinics in the Pirkanmaa Hospital District of Finland. The women were approximately 32 weeks' pregnant at enrolment.

The effect of mixing and consistency on cellulose cationization.

Traditional chemical modifications of cellulose are usually done at low or medium consistencies. Processing at high solids content is expected to provide a leap forward in reduction of manufacturing costs such as minimization of chemical use, energy consumption and decreasing processing equipment size, while at the same time increasing reaction efficiency. In this research, high consistency modifications of cellulose were studied through cationization reaction.

The acoustic voice quality index version 02.02 in the Finnish-speaking population.

The Acoustic Voice Quality Index (AVQI) is a multiparametric tool for objectively measuring the general acoustic characteristics of voice. The AVQI uses both sustained vowel and continuous speech in its analysis, and therefore, a validation is required for different languages. In the present study, validation was performed in the Finnish-speaking population.

Conversion of polar and non-polar algae oil lipids to fatty acid methyl esters with solid acid catalysts--A model compound study.

Bio-based fuels are becoming more and more important due to the depleting fossil resources. The production of biodiesel from algae oil is challenging compared to terrestrial vegetable oils, as algae oil consists of polar fatty acids, such as phospholipids and glycolipids, as well as non-polar triglycerides and free fatty acids common in vegetable oils. It is shown that a single sulphonated solid acid catalyst can perform the esterification and transesterification reactions of both polar and non-polar lipids.
