How to use backscatter radio for soil sensor network.

The ever growing population and climate change has put pressure on food producers to come up with strategies to feed the populace using smart means so as not to disrupt the ecosystem. The internet of things has delved into agriculture,thus making it easy to monitor agricultural activities with sensors, radio frequency identification, drones and robots. The use of various gadgets to facilitate increased productivity has pushed technology into the agricultural land to ensure food security. One of such innovative method is the use of backscatter radio for soil sensor, the Soil Moisture Scatter Radio Networking with Low Power by Spyridon-Nektarios Daskalakis. The soil sensor switches half of an etched PCB bowtie antenna in and out of a circuit at a frequency proportional to soil moisture. A carrier signal from a separate transmitter is reflected off the alternately loaded and unloaded antenna, picking up subcarriers with a frequency proportional to soil moisture.

ICRA : Building agribusiness relations for sustainable profit .

Over the years, ICRA experienced that many business support services (BSS) face difficulties in offering services that have long-lasting impact.

Banaba Leaf Extract: A Natural Diabetes Remedy.

According to the American Diabetes Association, 25.8 million children and adults in the US have diabetes. That's 8.3% of the population and represents a 14-fold increase since 1960. This high growth has led to a growing number of pharmaceutical drugs attempting to treat the problem -- and with those drugs, a host of dangerous side effects, such as increased risk of heart failure. It's no wonder people are looking for safer, and possibly more effective, natural alternatives. Fortunately, there just might be a powerful natural alternative with banaba leaf extract. Banaba leaf, not to be confused with “banana” leaf, has been used for thousands of years in India and the Philippines to naturally treat diabetes and low blood sugar levels. It turns out these cultures were onto something -- banaba leaf and blood sugar control go hand in hand. The blood sugar regulating properties of corosolic acid, the active ingredient in banaba leaf, have been demonstrated in cell culture, animal, and human studies. In isolated cells, for example, it is known to stimulate glucose uptake. In fact, some studies have shown that it can help lower blood sugar within sixty minutes. It has also been shown to help correct leptin problems and food cravings that are typically found in overweight individuals who have elevated blood sugar. continue

3 people in Ontario contract Seoul virus spread by rats.Ontario's chief medical officer of health says three people have contracted a virus linked to exposure to rats. Dr. David Williams says the Ministry of Health and Long-Term Care is investigating three human cases of Seoul virus among people who had prolonged contact with rats. Williams says no serious health problems have been reported. Seoul virus is a type of hantavirus that can be transmitted from rats to people through bite wounds or exposure to urine, feces, saliva or contaminated bedding. Officials say the health risk to Ontarians is considered low and Seoul virus is not spread from person to person.Rats do not show symptoms of disease when they are infected with Seoul virus. A person infected with Seoul virus may not develop symptoms or will only develop very mild symptoms. However, in some instances, more severe symptoms may include fever, severe headache, back and abdominal pain, chills, blurred vision, redness of the eyes, or rash. source

At age 29, he still had plenty of NFL years ahead of him. He wasn't playing at the level he was in 2009, but his career was far from over. He had interest from numerous teams, including an offer from the Baltimore Ravens. Brown is doing this to help the less fortunate. He grows sweet potatoes and other vegetables and donates his harvest to food pantries. According to the New & Observer, he has given away 46,000 pounds of sweet potatoes and 10,000 pounds of cucumbers this fall. more

Saving The Rhinos With GPS Sensors.

Save the Rhino numbers show there are just 29,000 rhinos left in the world; only 20 years ago this number was closer to 500,000. In an attempt to slow this devastating decline, researchers from the Sigfox Foundation are fitting the wild animals with sensors to track their movement. By tracking the animals, the researchers can protect them from poachers, for example, and better understand their habits to encourage them to breed and ultimately conserve the species. Over the past six months, the prototype GPS trackers, developed by the foundation in association with the Loweld Rhino Trust, have been implanted in the horns of 10 black and white rhinos. This prototype securely sends three GPS signals per day, to three base stations and via the Eutelesat satellite, to local teams through a dedicated secured platform, also developed internally at Sigfox more
