- In 2018, Endeavour issued a $330 million convertible note and subsequently downsized its $500 million revolving credit facility to $350 million.

Is the H8 collapse just another confounding Oak Island occurrence? Could it be a sign of another ingeniously designed booby trap? Or will their search in the Money Pit be over for good?

In India, where MC is a mark of religious affiliation, 41% of mostly Hindu men were concerned that MC was not part of their culture, while 30% were afraid of stigma or rejection [110].

It has been suggested that MC in India might be more acceptable to STI clinic attendees than others [178].

The advantages of the new method are enormous as there are countless fibre-optic cables spanning the globe in the dense telecommunication network. Especially beneath megacities with high seismic hazards, such as San Francisco, Mexico City, Tokyo, or Istanbul, and many others, such cables could provide a cost efficient and widely spread addition to existing seismological measuring devices.

The mode of pumping should also be reviewed to ensure that the borehole is delivering the required volumes of water in the most efficient and cost-effective manner.

With the money earned from the drill bit patent, 19-year-old Howard Hughes Jr. expanded the oilfield fortune while making movies, setting aviation records and helping build much of Las Vegas. Hughes Tool engineers invented the tri-cone bit in 1933.

Jon Gertner writes frequently for the magazine about science and technology. He last wrote about Tesla’s effort to build self-driving cars.

The machine’s small size and ability to work autonomously intrigued scientists with the BAS, who were looking for ways to drill into bedrock sitting at the bottom of a deep ice borehole. Antarctic scientists have portable drill systems for the relatively soft ice, but boring into the hard rock beneath presents a logistical challenge for scientists working on the remote continent, including shipping in a large drilling rig.

- FY-2019 production expected to increase to 615-695koz and AISC expected to remain low at $760-810/oz

Advertising alcoholic beverages have been banned in India as per the Cable Television Network (Regulation) Amendment Bill which came into effect on 8 September 2000. Private channels often permit alcohol companies to advertise using the surrogate route and that is why we see major liquor brands promoting and advertising themselves for their club sodas, mineral water, CDs or playing cards to hammer the brand name into the heads of consumers.
