The work, published in the Pertanika Journal of Science and Technology, suggests which factors should be taken into account before drilling for industrial and residential water supplies, as groundwater becomes a more important resource worldwide.
Groundwater has been used for centuries, but its usage is still limited to shallow, unconfined aquifers using hand-dug wells, or deeper wells on coarse sand aquifers. With much of the country’s industry based on hard rock, Nasiman Sapari and colleagues from the Universiti Teknologi PETRONAS analysed data from 136 industrial tube well drillings into hard rock.They found that these wells could yield up to 890 cubic metres per well per day – though the average was 343 cubic metres. 103 of the tube wells were productive, and the data show that those that penetrate weathered granite were generally non productive so these conditions can be avoided in future. Their analysis of the quality shows it is generally fresh water, with only 9% producing water harder than recommended for drinking. 42% had iron levels lower than the WHO standard.

Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal ‘small’, the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.
Around the world, researchers are attempting to shrink data storage devices to achieve as large a storage capacity in as small a space as possible. In almost...
The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.
Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...
What if, instead of turning up the thermostat, you could warm up with high-tech, flexible patches sewn into your clothes - while significantly reducing your...
A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
