Cefic, on behalf of WONIPA, which represents in this case a group of manufacturers of NC membrane filters, which accounts for 80 % of the worldwide production of NC membrane filters for diagnostic and life science applications, presented in informal document INF.16 (sixtieth session of the Sub-Committee) a complete set of test results with UN 1(a) and UN N.1 tests for a group of NC membrane filters. (...) For the billions of COVID-19 rapid test devices, billions of NC membrane filters are needed as substrate. Cefic, respectively WONIPA, presents a packaging concept of the manufacturers of NC membrane filters which will simplify the transport of NC membrane filters. The simplification of the transport of NC membrane filters will improve the availability of the NC membrane filter for COVID-19 rapid test devices worldwide and by this improve the control of the COVID-19 pandemic.

Position of synthetic membrane ending in anchor trenches (e) Lay a first strip of the membrane along the width of the pond and along the dike. Watch for the following: choosing the correct slack for the membrane used (see Table 4) ; leaving 20 to 25 cm of the membrane in the bottom of the anchor trench at both ends; avoiding soil on top of the membrane; avoiding puncturing the membrane while handling it. (...) Bring the membrane at least 10 cm up the sides of the monk or around the pipe, and make sure the membrane is not split around the joint.

Due to the stochastic opening and closing of ion an intact and suf iciently thick sheath, ion leakage from channels, which can be described via nonlinear differen‑ the neuron membrane is minimal. As a result, attenua‑ tial equations of Hodgkin Huxley formalism, membrane tion at the membrane potential is also minimal. (...) On demyelination, which is the loss of myelin sheath, can in‑ the other hand, since passive compartments have only a crease ion leakage from the axon membrane to a level negligible number of ion channels, membrane resistance that the membrane potential attenuates too much when does not depend on time, and the axon acts linearly at in‑ it reaches the next node. In this case, low membrane po‑ ternodes. + tential may not be suf icient to open Na channels in the node, and consequently, AP propagation is blocked [15].

The main function of an intermediate sand layer is to protect the membrane from being punctured by hexagonal plates during installation. The advantage of this option is the lower consumption of raw material in the production of the HDPE membrane, and that it can be produced locally in a short time. (...) Size of the product (membrane): width from 2000 mm, thickness 0.5mm +/- 10%.

These workers were trained by Sascha Meyer, a German expert with over 15 years’ experience of membrane manufacturing and installation. Sascha showed the workers how to erect the steel and install the membranes.

Page 1 of 7 Industrial wastewater reclamation technology for urban irrigation Piet DuPisani, Head of the Water and Wastewater Department of the City of Windhoek Type of tool: technology for efficient water use, specifically: industrial wastewater treatment for reuse (irrigation) using a modified process technology for local operations, including MBR (membrane bio-reactor) and UV-disinfection Issue: industry, agriculture Location: City of Windhoek, Namibia, Africa. (...) Page 3 of 7 Figure 3. The membrane bioreactor with membrane units visible underwater (left), the membrane bioreactor aerated (right) Figure 4. UV radiation unit for post disinfection of reclaimed wastewater for irrigation Page 4 of 7 The drivers of technological change The membrane biological process – adapted to local conditions and with some simplification of the process technology – has made it possible to build a plant of the size and standards under discussion here.

As it happened, the Tech Access Partnership’s repository of technologies included a nanofiber filtration membrane designed to be used in medical-grade masks. It was developed by a Turkish company MEMSIS, that specializes in membrane systems used in water filtration and treatment.     (...) But MEMSIS has agreed to sell him small amounts of its membrane during this start-up phase. This means Mario doesn’t have to spend time raising large amounts of money to get started.
