DIGITAL TRANSACTION

Digital transaction: ___ ____ Prologue: History of banking dates back to 2000 B.C. Archaeologists believe that depositing and lending have always been human way of business and economy during renowned Roman, Chinese, and Indian empires. In fact, if we really think about it, there can actually be no trusted way of keeping earned money safe to be used when required other than a trusted group that also provides interest on such deposits.

ANTIMICROBIAL RESISTANCE (AMR)

Antimicrobial resistance (AMR): ______ ______ Prologue: Within a few days of scraping his leg in a scooter accident in 2009, nine-year-old Brock Wade was in hospital fighting for his life with a methicillin-resistant staphylococcus aureus (MRSA) infection. Once the infection – caused by one of the bacteria most often resistant to antibiotics – has been diagnosed, doctors put him on five different antibiotics. After a month in the hospital, and against all odds, Brock recovered and was well enough to come home. Scenarios such as this case are increasingly being played out all over the world. But not all the thousands of patients that contract drug-resistant bacterial infections every year are as lucky as Brock. And the problem looks set to get worse.

HEARING AID

HEARING AID: _______ _______ Prologue: I was working in Saudi Arabia as a doctor from 2001 to 2006. I was designated female medical specialist. All female medical patients used to come to me for treatment. I noticed that I cannot hear properly what they say. The language barrier and lack of lip reading (Muslim women wear burka covering their face) compounded hearing disability.  I got myself checked and found that I was suffering from otosclerosis. I started wearing hearing aid which improved my hearing significantly. Although one should remove hearing aids while sleeping at night, I used to wear hearing aid in one ear and sleep on side with ear having hearing aid on the top to attend night calls for emergency. In 2007/2008, I got operated in both ears, and after surgery my hearing improved so much that I did not need hearing aid. Hearing is one of the […]

DRIVERLESS CAR

DRIVERLESS CAR: _____ _____ Prologue: Karl Benz invented the automobile in 1885. Later that year Benz took it out for the first public test drive and he crashed into a wall. Car crash trend continues till date. In spite of stronger cars, extra seat belts, and air bags, 1.25 million people are killed on the world’s roads every year. What could have prevented the accident? The obvious answer is that you could have — by paying attention. Driver error is the most common cause of traffic accidents, and with cell phones, drunken driving, in-car entertainment systems, more traffic and more complicated road systems, it isn’t likely to go away. But if drivers aren’t going to concentrate on the road, who is? If technology continues on its current course, your car will do the concentrating for you. Automakers are developing complex systems that allow cars to drive themselves. Machines are much […]
