Disappointment for Cumbrian hammer thrower Nick Miller at the European Athletics Championships | Rock Drill Bit Grinding Machine

The majority of the licensed independent water supplies in the UK were constructed before 1940. For those companies using such independent supplies, there is a real commercial need to protect this business critical resource and protect boreholes from failure. The first step to understanding your borehole is to understand the hydrogeology and the target aquifer that is providing the water. This might comprise a desk study to highlight potential problems with yield and water quality, based on readily available geological and hydrogeological information. The outcome should be an initial conceptual model and risk assessment of the borehole in the context of the wider geo-environmental setting, which if necessary can then be tested, reviewed and validated using data obtained from invasive investigations.

Production totaled 277koz, significantly exceeding full-year guidance of 250-260koz due mainly to both the mining activities and the process plant performing above their nameplate capacities.

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.

The experts then hope to dig a horizontal tunnel to the spot where they believe the boy is trapped in the borehole.

The advent of the AIDS epidemic in the 1980s re-focused interest on MC as a means of prevention of not just HIV, but other sexually transmitted infections (STIs) and adverse medical conditions. This has led to MC programs in high-HIV prevalence settings of sub-Saharan Africa focused on men for more immediate reductions in HIV incidence, but considerable interest has also been given to encouraging infant MC for longer-term gains [10, 11]. There have as well been recent calls for the promotion of infant MC in the USA [12, 13], the UK [14], Australia [15] and sub-Saharan Africa [16, 17].

The Kalana Main resource estimate is robust based on a lower gold price pit shell, as shown in the table below.

At Climeworks’s offices in Zurich, I asked Valentin Gutknecht, who was at the time the company’s business-development manager, if he could bury in Iceland my emissions from my plane flight from the United States to Zurich. He had a written agreement he could print out and give me, but it wouldn’t be cheap, he warned. The price was running about $600 a metric ton, meaning my flight would cost about an extra $700. But I was hardly the first person to ask him. The weekend before, Gutknecht told me, he received 900 unsolicited inquiries by email. Many were from potential customers who wanted to know how soon Climeworks could bury their CO₂ emissions, or how much a machine might cost them. I had the sense I was getting a glimpse of what’s to come: A community of people — not large enough to make a difference, but nonetheless motivated — seemed ready to pay a premium to reverse their CO₂ emissions.

“The idea of bringing direct air capture up to 10 billion tons by the middle or later part of the century is such a herculean task it would require an industrial scale-up the likes of which the world has never seen,” Princeton’s Stephen Pacala told me. And yet Pacala wasn’t pessimistic about making a start. He seemed to think it was necessary for the federal government to begin with significant research and investments in the technology — to see how far and fast it could move forward, so that it’s ready as soon as possible. At Climeworks, Gebald and Wurzbacher spoke in similar terms, asserting that the conversations around climate challenges are moving beyond the choice between clean energy or carbon removal. Both will be necessary.

Results showed that silica dust generated by the pneumatic rock drill was at least 444 times greater than OSHA’s permissible exposure limit of 50 micrograms per cubic meter of air over an 8-hour time-weighted average, whereas with the electric drill, silica dust was 11 times greater than the PEL.

Since Italy at its ports for migrants has largely closed, to come less and less migrants from Libya. However, people on the dangerous Crossing still die. Since the beginning of the year, 83 people were killed according to the International organization for Migration in the Mediterranean. In the prior-year period, there were 199.

Club conundrum: Forward thinking. It cannot be as turbulent as last year, can it? Defence coach Scott Hansen, sacked. Director of rugby Richard Cockerill, sacked. Head coach Aaron Mauger, sacked. The last coach to take them to a Premiership title Matt O’Connor, reinstated. Arguments of brains or brawn still abound and O’Connor has decided to draft in a superb backline – Youngs, Ford, Toomua, Tuilagi, May, Veainu, Tait. Nice. But will the forward give them enough platform? It’s odd to think that the Tigers’ pack could let them down.

The tunnel will accommodate a tube 2.6 metres wide, the deepest potable-water pipe in the world, that will pump (mostly desalinated) water through 30km of tunnel from sea-level to an elevation of 860 metres to supply much of Jerusalem’s drinking-water needs. In a country famous for its ambitious water-supply schemes, this is the biggest since the 1960s. It was in 1964 that Israel inaugurated its National Water Carrier, a public-works project to bring water from the north of the country down to the Negev desert in the south. It was an emblem of the young country’s determination to survive. And it is a dominant theme in water policy to this day. In a dramatic symbol of a determination to shape the natural order to human needs, the direction of water-flow in the national carrier is to be reversed, to give clean, desalinated water back to “nature” in the north of the country.
