Food safety knowledge, sources thereof and self-reported behaviour among university students in Sweden

International studies have noted shortcomings in food safety knowledge and behaviour among university students. In general students do not constitute a pronounced risk group but there are wider implications. In a foreseeable future some of them will become pregnant and a majority will be responsible for vulnerable groups in their near environment. A crucial question exists, therefore, about their

Excitation wavelength dependence of photoluminescence flickering in degraded MAPbI3 perovskite and its connection to lead iodide formation

Metal halide perovskite semiconductors often exhibit photoluminescence blinking and flickering when luminescence of individual small nano- or even microcrystals is monitored. The nature of these fluctuations is not well understood but must be related to the presence of metastable non-radiative recombination channels and efficient charge migration in these materials. Here we report on the excitatio

Enhancing performance in anaerobic high-solids stratified bed digesters by straw bed implementation

Anaerobic high-solids single-stage stratified bed digesters have been found to be simple and flexible design candidates for small-scale reactors located in medium- to low-technology environments. In the present study, wheat straw was used as the starter material for the stratified bed. Upon green mass feeding, the anaerobically stabilised straw bed functioned both as a biofilm support and as a par

A network model and numerical simulations of flow distributions in packed bed reactors with different packing structures

Due to the high specific surface area, packed bed reactors are widely used in real engineering applications. The flow distribution, which is highly dependent on the packing structure, can be vital for the heat/mass transfer and reaction performances. This makes the study of the flow distribution in packed beds quite important. In the present paper, an equivalent network model based on the Voronoi

CGRP in rat mesenteric artery and vein - receptor expression, CGRP presence and potential roles

CGRP is a potent dilator of arteries and despite rich perivascular CGRP immunoreactivity in both arteries and veins the role of CGRP in veins remains unknown. The aim of the current study was to compare perivascular CGRP immunoreactivity and expression of CGRP receptor mRNA and CGRP receptor immunoreactivity in rat mesenteric arteries and veins. Furthermore, potential vasomotor effects of CGRP wer

An improved method to visualize two regions of interest synchronously in microfluidics

Multiphase flow in mini/micro channels has been widely studied for its potential in many industrial applications. The normal experimental method cannot capture two separate regions of interest (ROI) with a long distance synchronously for the limited field of views. In order to solve this problem, an improved experimental method is proposed and validated with experimental results. Prism groups are
