Abstract: A device is provided that allows for repeated electrical connection of an integrated circuit. The device includes a top, an alignment plate, a connector and a bottom. The top, alignment plate, connector and bottom each have first and second sides facing opposite directions, with the top, alignment plate, connector and bottom being stacked in a vertical orientation. The top is vertically moveable relative to the alignment plate to secure the integrated circuit adjacent to an edge of the connector, with the edge extending from a space between the first and second sides thereof.

Abstract: Humic acid salts are produced, with a high output of useful products, by a liquid-phase oxidation of the mixture of an alkaline agent with a lignin-containing plant raw material having the total content of dry substances of 12-20%, said oxidation being carried out in two stages. In a first stage, pre-oxidation is carried out at a temperature of 50-190 DEG C. and a pressure of 0.5-3 MPa associated with simultaneous treatment with an oxygen-containing gas until a pH of 10.5-12 is reached. The second stage, i.e. oxidation is carried out in the similar conditions at a temperature of 170-200 DEG C. until a pH of 8.5-10 is reached. The by-product of cellulose production by a sulphite process, i.e. concentrated solutions of lignosulphonate or lignin is used as a lignin-containing plant raw material, said lignin being a by-product of hydrolysis production being continuously oxidised by air oxygen in two stages.

Abstract: An instrument for measuring sub-pico Tesla magnetic fields using a superconducting quantum interference device (SQUID) inductively coupled to an unshielded gradiometer includes a filter for filtering magnetically—and electrically coupled radio frequency interference (RFI) away from the SQUID. This RFI is principally coupled to the SQUID via the unshielded gradiometer. In addition, a shielding enclosure is used to electromagnetically shield the filter circuit from the SQUID, and a method is employed to increase the impedance between the input coil and the SQUID without diminishing the overall sensitivity of the instrument.
