A simple electrical conductivity could be enough to measure water pollution in tropical rivers instead of the complex tests currently used, according to a paper in the Pertanika Journal of Tropical Agricultural Science (JTAS)
A simple test of electrical conductivity could be used as a parameter for water quality, according to new research published in the Journal of Tropical and Agricultural Sciences.

The research investigated whether this single parameter could be used instead of the more complex current tests used in Malaysia to measure water pollution. The author believes the test should be included in the water quality index in the future.
Currently, the Malaysian Water Quality Index (WQI) is based on six water parameters. This allows a lot of data to be broken down into six measures, but there are weaknesses, and it is certainly not comprehensive.
The use of conductivity tests can inform of sulfate, bicarbonate, and chlorides of calcium, magnesium, and sodium in water, and is used in some still water lakes, but isn’t currently used in running rivers.
Yap CK, from Universiti Putra Malaysia, took nine periodic samplings at eight sites along the Malaysian Langat river, including both polluted downstream and unpolluted upstream sites.
The results show that there are consistently higher levels of electrical conductivity in the more polluted downstream, and this was in line with two current measures – dissolved oxygen and suspended solids.
Since it is much easier and faster to measure electrical than these two factors, its use as a single indicator of water pollution in tropical rivers is proposed.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
