Temporary shelter for the homeless
… Yoshimura pattern. It is collapsible, wind and water resistant, and structurally rigid. The design is a prototype made from commonly available cardboard sheets and suggests how this material can be manipulated in future models.

The physical activity status and patterns in adults with Cerebral Palsy - an accelerometry study
… Unfortunately, the Actigraph is not water resistant, which does not allow individuals to continuously wear the device. Alternatively, wrist-worn devices can be used to assess PA levels, such as the Polar Loop 2, which is convenient to wear and water-resistant. However, no previous …

Performance and Usability of Flexible Membrane Keyboards
… silicon rubber, thus it is fully flexible and water resistant. Although a number of flexible keyboard characteristics are the same as standard keyboards (i.e. key size, shape and spacing), key-switch and key clicking mechanisms are inherently different. Since there is little or no existing …

Pilot-scale production and physicochemical properties of mycelium-based materials and diversity assessment of a fungal biobank
… insulation, and other applications. Lightweight, water-resistant biomaterials can be produced by using mycelium as a binding agent for agricultural byproducts. In this study, we investigated the production and physicochemical properties—dry density, moisture content, and water absorption—of …

Drying Oils Treated by Irradiation as Coatings for Biobased Films
… However, their performance with respect to water and gas barrier properties is inferior to current packaging products on market. Drying oils are promising as film coatings to improve water barrier properties of protein-based films. Drying oils undergo autoxidation after a period exposure to …

Determination of the service life of concrete sealers on horizontal and vertical bridge members
… of concrete surface sealers which form water-resistant barriers and reduce chloride intrusion. It is imperative to know how effective sealers are and how long sealers retain their effectiveness in order to plan reapplication and estimate life cycle costs for comparison to other …

The chlorination of sulfate lignin
… solution. When precipitated from solution by ice water this chloro-lignin was a light yellow powder with a chlorine percentage as high as 28.0 per cent. Increasing the rate or chlorine flow trom 0.472 to 1.084 gm Cl₂/min. during tests at 25°C resulted in increasing the rate of chlorination from …
