Forest plot showing association between circumcision and penile inflammation in 8 studies [38–45]. The meta-analysis shown does not include an anomalous outlier study [46], which when included led to significant between-study heterogeneity (P = 0.03), but when excluded no significant heterogeneity remained (P = 0.40).

The leading engineer in Spain’s search for a two-year-old boy trapped in a deep, narrow borehole says rescuers are rushing to finish in days massive digging work that usually takes months.

Meanwhile, at Smith’s Cove, Marty asks the heavy equipment operator to cut deep trenches as part of the latest exploration effort. In just two months’ time, the team has uncovered a plethora of intriguing finds here, including wooden and concrete walls, massive U and L shaped structures, and a wooden slipway possibly over two centuries old. But the most significant find is what could be one of five stone box drains, part of an elaborate booby trap system.

Sportsmail’s verdict: 12th – relegated. Worcester have lost quite a few key men, and not added many. Their battle with Gloucester and London Irish will be tight, but the Warriors may well fall. 

Woskov laughs when he reveals that drilling engineers have a hard time believing his technology does not use the costly drilling mud they depend on. But, he explains, with a gyrotron, high-temperature physics will replace the mechanical functions of low-temperature mud, allowing drillers to extract rock matter through vaporization or displace the melt through pressurization. Similarly, the high temperature melted rock will seal the walls of the borehole, and the high pressure from the increased temperature will prevent collapse. In principle, because an increase in temperature in a confined volume will always result in an increase in pressure over local pressure, drillers could maintain the stability of a borehole to greater depths than possible with drilling muds.

The team hopes to collect Antarctic bedrock and measure radioactive isotopes such as beryllium-10 in it. This form of the element, formed by the reaction of cosmic rays with nitrogen and oxygen atoms, decays at a steady rate. So measuring how much of the isotope is in the rock now can reveal when the rocks were last uncovered by ice and exposed to the atmosphere, providing another window into the southernmost continent’s climatic past.

Sample 18 is also paper, dated to pre-1890. To that Rick says, “wow,” and asks what further testing can be done to precisely date the papers.

There is some concern about risk-compensation (the tendency to stop using condoms and increase the number of sexual partners) following MC, although in most studies in which men were counseled this was not seen [179, 180]. It has been suggested that neonatal MC may reduce the chances of a change in behavior due to circumcision status, as the male will not perceive any change in risk compared to what might transpire if the circumcision had taken place at an age when he might be sexually active [181].

Current rotary technology is a mechanical grinding process that is limited by rock hardness, deep pressures, and high temperatures. Specially designed “drilling mud,” pumped through the hollow drill pipe interior, is used to enable deep drilling and to remove the excess cuttings, returning them to the surface via the ring-shaped space between the drill pipe and borehole wall. The pressure of the mud also keeps the hole from collapsing, sealing, and strengthening the hole in the process. But there is a limit to the pressures such a borehole can withstand, and typically holes cannot be drilled beyond 30,000 feet (9 km).

In the West African state of Burkina Faso, the government resigned surprisingly. President Roch Kaboré, thank you government, chief Paul Kaba Thieba and his Ministers for their service, said the office of the heads of state late on Friday evening. There are no reasons for the resignation of the Cabinet were called.

Balance quality control and production rather than speed when motivating drillers. Otherwise, operators may take shortcuts to gain footage, but compromise safety and overall cost.
