Published 2019-07-01 by Tech Briefs Media Group in United States

Researchers have developed a biosensor that attaches to a smartphone and uses bacteria to detect unsafe arsenic levels. The device generates easy-to-interpret patterns similar to volume-bars that display the level of contamination.

Published 2018-08-29 by SAE International in United States
The greases have been classified according to the operating conditions under which they are used, because the versatile nature of greases makes it impractical to classify them according to end use. It will therefore be necessary to consult the supplier to be certain that the grease can be used in; for example, rolling bearings or pumped supply systems, and also concerning the compatibility of products (see Remarks in Table 1).

Bearings, Plain, Self-Aligning, Self-Lubricating, 300 cpm Oscillation (13 fpm), -65 to +160 °F (-54 to +71 °C), Liners Less Than 0.015 inches

ACBG Plain Bearing Committee
  • Aerospace Standard
  • AS82819
  • Current
Published 2018-08-23 by SAE International in United States
This standard covers the requirements for spherical, self-aligning, self-lubricating, bearings which are for use in the ambient temperature range of -65 to +160 °F (-54 to +71 °C) at high cyclic speeds 300 cpm (13 fpm) for liners with a thickness less than 0.015 inch. The scope of this standard is to provide a liner system qualification procedure for helicopter sliding bearings defined and controlled by source control drawings. Once a liner system is qualified, the source-controlled bearings are further tested under application conditions. Under Department of Defense (DoD) Policies and Procedures, any qualification requirements and associated Qualified Products List (QPLs) are mandatory for DoD contracts. Any materials relating to QPLs have not been adopted by SAE and are not part of this SAE technical document.

Project Helps Provide More Precise Detection and Understanding of Seismic Activity In Oklahoma

  • Magazine Article
  • TBMG-27509
Published 2017-09-01 by Tech Briefs Media Group in United States

Induced seismicity is earthquake activity that occurs because of changes in subsurface stress brought about by human activity. Using geology, geophysics, reservoir modeling, and rock mechanics to develop assessment models, this project evaluated the potential for, and increase in, seismic activity in central Oklahoma, including the relationship between oil and gas operations and induced seismicity. The study confirmed and more fully investigated the link between increased seismic activity and wastewater disposal, which significantly increased between July 1, 2014, and the end of 2015. Over the course of the study, more than 95 percent of the earthquakes in Oklahoma occurred in a small portion of the state, where about 70 percent of wastewater was injected.

Borrowing concepts from medical diagnostic devices, researchers have created a simple, inexpensive set of handheld tests that can detect the presence of many water- or food-borne pathogens. If applied in the field, such tests could greatly reduce the number of expensive follow-up tests needed to keep the food supply safe from fecal contamination.
