In both cases, he used the heavy-water method to monitor cell division.
Thus, India's Shree Cement, which has long suffered from water shortages, developed the world's most water-efficient method for making cement, in part by using air-cooling rather than water-cooling.
The website HowStuffWorks has a fascinating article about RISUG that covers its genesis as a method to purify drinking water.
TOHL, which stands for Tubing Operations for Humanitarian Logistics, has developed a simple method to deliver fresh water for emergency relief: install a really long plastic tube with a helicopter.
FORBES: Startup Aims To Install Pipelines With Helicopters...Seriously!
With complex purification technology beyond the reach of the many developing world communities that suffer from dangerously high levels of the toxic metalloid element in their water supply, this surprisingly simple method of filtration, could quite literally save lives.
FORBES: "Plastic Bottle" Filters Can Help Millions Poisoned by Arsenic-Contaminated Water
Other ideas include drilling into the aquifer beneath the city and pumping cool water along the tunnels (a method already used to cool the Royal Festival Hall), or installing chillers in the trains that would freeze blocks of ice while the trains were above ground which would then keep them frosty on the underground sections.
Other projects included a method for detecting toxins in water using glowing bacteria and studying the effect of nano particles on other bulk particles.
FORBES: Wait, Did This 15-Year-Old From Maryland Just Change Cancer Treatment?
The farmers' aquaculture method, which drew on underground water to fill their shrimp ponds, was causing the surrounding land to sink.
Among the various offshore drilling practices, ultra-deepwater drilling is the most expensive and technically challenging method since it involves drilling at water depths of over 5, 000 feet.
FORBES: Shell's Record Transocean Deal Shows The Importance Of Ultra-Deepwater
Scientists have just unveiled an easy-to-use, inexpensive method for removing arsenic from contaminated drinking water using chopped up bits of discarded plastic bottles.
FORBES: "Plastic Bottle" Filters Can Help Millions Poisoned by Arsenic-Contaminated Water
Microarrays also obtain genetic information from microbes in soil or water, and while less quantitative than qPCR, this method can analyze tens of thousands of genes at once.
The method uses biogas, which is produced when waste water sludge is broken down by microbes in a process known as anaerobic digestion.
In the study released Wednesday, researchers suggest extracting the natural gas hydrates with "depressurization" -- a method that involves changing the ice into gas and water at the surface.
It extracts oil from the ground using a method called fracking - pumping down a mixture of sand, water and chemicals at high pressure.
The method works because the electrical field polarises the electric charge on water molecules in the air around the icy tip and then draws them in electrostatically.
The method is being employed at a small test facility, where waste water is piped through a complex maze of equipment, including a membrane that removes the nasty stuff.
It clip highlights how an ancient Egyptian building method - the Nubian vault -, which requires only earth and water, was rediscovered by a Frenchman who transmitted this technique to Burkinabese masons.
The industry says the method is safe, but critics say it could cause earthquakes and pollute water sources.
Today, this efficient method is used in more than 100 countries to grow crops using less water, energy and fewer chemicals, including projects in South Africa, China, India and even for growing tea in Tanzania.
Their method was based on the observation that electrical currents will be induced in a conductor (such as water) when it is faced with a magnetic field that varies over time.
