SummaryLast year, the United States issued an Executive Order announcing the National Biotechnology and Biomanufacturing Initiative, a 2 billion dollar initiative supporting biotechnology and biomanufacturing innovations in health, climate change, energy, food security, agriculture and supply chain resilience. Together with their 2022 Inflation Reduction Act, investment for the commercial deployment of the whole bioeconomy across the entire supply chain is financially supported. The US is not alone – other countries are also developing their own initiatives.If Europe wants to keep its competitive position in the bio‐based industries, it needs a better recognition in EU policy and more regulatory foresight to bring innovative products to the market. Bio‐based products and materials have to be recognised as an important Carbon Capture and Utilisation tool, lowering the use of fossil fuels, and contributing to climate mitigation. The European bioeconomy is well‐positioned for finding a greener way to build a more robust economic base, reduce strategic dependencies and reinforce the supply of critical materials. However, to realise this, access to finance should be made easier and there needs to be sufficient supply of renewable feedstock.Although Europe has made good progress in recent years, more can and should be done to make the bio‐based industries a stronger part of a new sustainable growth and investment model. This article describes some possible recommendations.

Abstract The feasibility of laminar flow control technology for future wing is bound to the development of a leading edge high-lift system that complies with the requirements on smooth surfaces to enable maintaining the laminar boundary layer flow, such as a Krueger flap. Although in principle the aerodynamic performance of a Krueger flap is known, the unsteady behaviour of the flow during deployment and retraction is completely unknown. This is as even more important as during deployment the Krueger flap is exposed to highly unfavourable positions perpendicular to the flow. To mitigate the risk of unfavourable aircraft behaviour, it is therefore expected that a Krueger flap has to be deflected significantly fast and may trigger unsteady aerodynamic effects. Within the European H2020 project UHURA (Unsteady High-Lift Aerodynamics—Unsteady RANS Validation), currently a wind tunnel test is conducted incorporating the vented foldable bull nose Krueger flap. A wind tunnel model based on the DLR-F15 airfoil has been designed and manufactured that features a part span and a full span Krueger device, which can be actuated at high deflection rates up to 360°/s. First wind tunnel tests have been conducted at the ONERA L1 wind tunnel in Lille in October 2020. The tests included the measurements of internal forces, steady and unsteady pressures, as well as phase-locked Particle Image Velocimetry (PIV) to achieve high quality validation data for comparison with numerical methods.KeywordsAerodynmamicsHigh-lift systemKrueger flapUnsteady flowWind tunnel test

The Occupational Safety and Health Administration (OSHA) defines abrasive blasting as “using compressed air or water to direct a high-velocity stream of an abrasive material to clean an object or surface, remove burrs, apply a texture or prepare a surface for the application of paint or other type of coating.” OSHA regulations governing General Industry, Construction, and Shipyards mandate the use of abrasive-blast respirators approved by the National Institute for Occupational Safety and Health (NIOSH). Blast respirators are Type-CE supplied-air respirators, commonly known as “blast helmets.” This article will review and explain the components and the requirements pertaining to the use of these respirators. The OSHA regulations requiring the use of Type-CE respirators are cited in Figure 2 below.

Abstract Thermal spray is an important surface-modification process implemented by the steel industry. This article reviews thermal spray materials and equipment used and also provides examples of where typical coated components result in improved performance. It contains a table that lists thermal spray applications in the iron-steel manufacturing industry.

Matsutake mushrooms are able to grow in two kinds of ecological environments: coniferous forests and broadleaf forests. Japanese matsutake is a form of the matsutake mushroom that mainly appears in coniferous forests in the mid-latitude regions of Asia. In contrast, matsutake from Yunnan and Sichuan Provinces of China grows in broadleaf forests in low-latitude regions. The taxonomic relationship and the genetic distance between these two types of matsutake remain unclear. Here, we compared the random amplification of polymorphic DNA (RAPD) data and the sequences of the internal transcribed spacer (ITS) region and of variable domains V4, V6, and V9 of mitochondrial small subunit ribosomal DNA (mt SSU rDNA) to determine the genetic differences of Tricholoma matsutake strains collected from different ecological and geographic environments in Asia. We found few differences in the sequences of the variable domains, implying that all matsutake strains are the same biological species regardless of their host specificity and geographical differences. This conclusion is also supported by the sequences of the ITS region. On the other hand, RAPD analysis revealed that the matsutake mushrooms collected from different ecological environments have genetic differences and represent distinct varieties.

<div class="htmlview paragraph">In order to address the industry needs for value engineering and to continually improve the cost competitive position of reaction injection molded (RIM) automotive fascia, two technologies were investigated which can reduce part cost and maintain the key functional and stylistic properties necessary for a quality bumper cover. First, a review of how the addition of hollow glass microspheres into the polymer matrix is now being used in production. This microsphere addition has reduced both part weight and cost, and improved the process window in production to allow for improvements in defect rates, all with a negligible effect on physical properties and functional performance. Second, the paper reviews the validation studies to date on the concept of downgauging, or thin-walling, a RIM fascia. The data include a physical property review of the downgauged materials, and commentary on the effect that filler type has upon performance in these materials.</div>
