Rate of Felting of Untreated and Shrink-Resistant Wool Fabrics

Abstract: Shrinkage-time curves for a range of wool fabrics, and the effect of various shrink- proofing treatments on these curves, have been studied. Felting rates of untreated fabrics depend on fabric structure and applied force in the way previously established [e.g., 3, 13, 15]. The shrinkage-time curves of treated fabrics show two definite stages, an initial portion indicating a very low felting rate, followed by a second stage where felting may be much more rapid. For a given fabric structure and given applied force, the felting rates of both stages, and the times at which the second stage begins, depend on the degree of treatment. The two-stage curves indicate two distinct steps in the felting of the fabrics and are not due to the fibers being unevenly treated.Frictional properties of treated Merino 64's fibers show no correlation with shrink resistance, and the results are qualitatively different from those found with Lincoln 36's.The importance of defining washing conditions when testing shrink-resistant w...

Ribosome-Profiling Reveals Restricted Post Transcriptional Expression of Antiviral Cytokines and Transcription Factors during SARS-CoV-2 Infection.

Abstract: The global COVID-19 pandemic caused by SARS-CoV-2 has resulted in over 2.2 million deaths. Disease outcomes range from asymptomatic to severe with, so far, minimal genotypic change to the virus so understanding the host response is paramount. Transcriptomics has become incredibly important in understanding host-pathogen interactions; however, post-transcriptional regulation plays an important role in infection and immunity through translation and mRNA stability, allowing tight control over potent host responses by both the host and the invading virus. Here, we apply ribosome profiling to assess post-transcriptional regulation of host genes during SARS-CoV-2 infection of a human lung epithelial cell line (Calu-3). We have identified numerous transcription factors (JUN, ZBTB20, ATF3, HIVEP2 and EGR1) as well as select antiviral cytokine genes, namely IFNB1, IFNL1,2 and 3, IL-6 and CCL5, that are restricted at the post-transcriptional level by SARS-CoV-2 infection and discuss the impact this would have on the host response to infection. This early phase restriction of antiviral transcripts in the lungs may allow high viral load and consequent immune dysregulation typically seen in SARS-CoV-2 infection.

Cam Forces in Weft Knitting

Abstract: A technique is described for assessing tension in the yarn during knitting by measuring the needle-butt reaction forces on the cam. Results are given which illus trate the first-order effects of the major knitting variables.Two extremes of cam shape were investigated and it was found that a flat-bottom stitch cam gave rise to a remarkably constant stitch length. Cam force measurements suggested that the flat-bottom cam gave lower knitting tensions than the. pointed cam. There appears to be a good case for investigating the practicality of flat-bottom cams in flat-bed knitting machines.It is also found that, when knitting a very tight stitch, the peak yarn tension can occur in the loop being cast off before it reaches the widest part of the needle. An explanation is given for this effect.

Identifying the views of adolescents in five European countries on the drivers of obesity using group model building.

Abstract: BACKGROUND: To make effective progress towards a global reduction in obesity prevalence, there needs to be a focus on broader structural factors, beyond individual-level drivers of diet and physical activity. This article describes the use of a systems framework to develop obesity prevention policies with adolescents. The aim of this research was to use the group model building (GMB) method to identify young people's perceptions of the drivers of adolescent obesity in five European countries, as part of the EU-funded Co-Create project. METHODS: We used GMB with four groups of 16-18-year-olds in schools in each of the five European countries (The Netherlands, Norway, Poland, Portugal and the UK) to create causal loop diagrams (CLDs) representing their perceptions of the drivers of adolescent obesity. The maps were then merged into one, using a new protocol. RESULTS: Two hundred and fifty-seven participants, aged 16-18 years, engaged in 20 separate system mapping groups, each of which generated 1 CLD. The findings were largely congruent between the countries. Three feedback loops in the merged diagram particularly stand out: commercial drivers of unhealthy diets; mental health and unhealthy diets; social media use, body image and motivation to exercise. CONCLUSIONS: GMB provides a novel way of eliciting from young people the system-based drivers of obesity that are relevant to them. Mental health issues, social media use and commercial practices were considered by the young people to be key drivers of adolescent obesity, subjects that have thus far had little or no coverage in research and policy.
