Worldwide 1 in 3 males are circumcised [1, 2], totaling an estimated 1.2 billion [2]. In the USA, medical MC is performed on 1.2 million newborns (56% of baby boys) in community hospitals annually [3, 4]. The true number is higher because some boys are circumcised in ambulatory facilities, a physician’s clinic or in a private home. In other developed countries infancy is also the most common time for performing MC, whereas in non-Muslim developing countries MC is usually part of coming-of-age ceremonies where risks are usually greater [5]. The largest number of circumcised males are Muslims (approx. 70% of circumcised males globally) [1].

Best signing: George Ford – he won’t be around all year, as England commitments will keep him away from his new/old club, but Ford is one of the best 10s on the planet. He was not himself at Bath last year but rediscovered his touch in Argentina, now to boss the league again.

MARVEL Avengers Academy, Free Avengers Academy is actually doing something based on the school part of the premise again? Excuse me, I need to sit down for a second. The shock is just… too much. Wait, Hydra attacked and took over some Ultron-bots and school is canceled in favor of punching bad guys? Now there’s the Avengers Academy I know and can’t seem to quit. After an absolutely horrible Agents of S.H.I.E.L.D. event, this little two-week palate cleanser gives you the chance to get Devil Dinosaur, Crimson Dynamo, Thor, Nadia Van Dyne, and others. Nadia is particularly hard to recruit, but hey, that’s where we’re at with this app these days.

Atlas Copco Secoroc presents the all-new Secoroc TRB drill bit range – the latest in soft rock drilling. Aimed at production drillers, this unique drill bit offers a greater penetration rate than any other bit – a penetration rate that is also sustainable throughout the bit’s service life.

- Depreciation and depletion increased for the period due to accelerated depreciation taken on the heap leach assets as it nears the end of mine life.

Drilling methods are generally categorised as either ‘percussion’ or ‘rotary’, depending on the principal drilling technique employed. Some methods use a combination of both techniques.

- The Ball and SAG mill commissioning has been completed and, in preparation for production, ore was introduced into the process plant milling circuit with all the CIL tanks filled and agitators commissioned.

For the moment, skeptics of Climeworks’s business plan are correct: The company is not turning a profit. To build and install the 18 units at Hinwil, hand-assembled in a second-floor workshop in Zurich, cost between $3 million and $4 million, which is the primary reason it costs the firm between $500 and $600 to remove a metric ton of CO₂ from the air. Even as the company has attracted about $50 million in private investments and grants, it faces the same daunting task that confronted Carl Bosch a century ago: How much can it bring costs down? And how fast can it scale up?

Even the most enthusiastic believers in direct air capture stop short of describing it as a miracle technology. It’s more frequently described as an old idea — “scrubbers” that remove CO₂ have been used in submarines since at least the 1950s — that is being radically upgraded for a variety of new applications. It’s arguably the case, in fact, that when it comes to reducing our carbon emissions, direct air capture will be seen as an option that’s too expensive and too modest in impact. “The only way that direct air capture becomes meaningful is if we do all the other things we need to do promptly,” Hal Harvey, a California energy analyst who studies climate-friendly technologies and policies, told me recently. Harvey and others make the case that the biggest, fastest and cheapest gains in addressing atmospheric carbon will come from switching our power grid to renewable energy or low-carbon electricity; from transitioning to electric vehicles and imposing stricter mileage regulations on gas-powered cars and trucks; and from requiring more energy-efficient buildings and appliances. In short, the best way to start making progress toward a decarbonized world is not to rev up millions of air capture machines right now. It’s to stop putting CO₂ in the atmosphere in the first place.

Production models of the Sharp-Hughes Tool Company coned bit became a crucial (and exclusively patented) tool for drilling deeper wells, beginning in Texas and then around the world.

- A total of 135 veins within 61 vein packages were individually modelled as opposed to the previous approach of applying geostatistics to 56 grouped vein packages, and thereby provided an upgraded confidence in the vein packages/domain boundaries.

Production decreased and AISC increased mainly due to a decrease in processed grades following the completion of the high-grade Kofi C pit in 2017 and Kofi B pit in H1-2018.
