There is also some evidence that MC protects against prostate cancer, a malignancy associated with a history of STIs (see reviews [9, 54, 86]).

Led by tractors, tens of thousands of people in Berlin have demanded a turn to more environmental protection and animal welfare in agriculture. Under the Motto “We have the agricultural industry fed up” led the March on the occasion of the food exhibition Green week through the government district. According to the organizers, 35,000 people took part in the Protest. A Berlin meeting of the agricultural Ministers conference, called for more global cooperation in enhancing the digitisation of agriculture.

- Royalties paid increased due to both greater gold sales and a higher realized gold price, representing approximately $67/oz sold for 2018 compared to $59/oz for 2017.

The two men were not alone in trying to chip away at decades of carbon emissions. An American start-up, Global Thermostat, now finishing its first commercial plant in Alabama, began working on air-capture machines in 2010. And almost from the start, Gebald and Wurzbacher found themselves in a friendly competition with David Keith, the Harvard engineering professor who had just started Carbon Engineering in British Columbia. Keith’s company settled on a different air-capture technology — employing a higher-heat process, and a liquid solution to capture CO₂ — to brew synthetic fuels. Climeworks’s big advantage is that it can make smaller plants early, Keith told me: “I am crazy jealous. It’s because they’re using a modular design, and we’re not.” On the other hand, Keith said he believes his firm is closer to building a big plant that could capture carbon at a more reasonable cost and produce substantial amounts of fuel. “I don’t see a path for them to match this.” Gebald told me he thinks his and Keith’s companies will each succeed with differing approaches. For now, what all the founders have in common is a belief that the cost of capturing a ton of carbon will soon drop sharply.

Spanish miners and engineers have been joined by workers from a Swedish firm who, in 2010, helped to locate 33 Chilean miners who were then rescued after 69 days underground.

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.

For greater safety and efficiency in underground mining, Epiroc releases a number of automation features for the Scooptram underground loader. The Scooptram Automation Regular package allows the Scooptram to be controlled through an operator station from a remote location.

From an after-market perspective, Hedley explains that over their many years of experience with the equipment, Booysen Bore has developed the necessary competencies and technical skills to maintain their fleet to maximum availability levels.  From their well-equipped workshop at the Kuruman head office they are able to service, repair, maintain, refurbish and even self-manufacture certain components. “We are always willing to extend our support through Cobus and our Kuruman office as required by Booysen Bore. We remain committed to growing this longstanding partnership through continued close collaboration with Booysen Bore,” concludes Hedley.

Their view is not always shared by outside observers. M.I.T.’s Howard Herzog, for instance, an engineer who has spent years looking at the potential for these machines, told me that he thinks the costs will remain between $600 and $1,000 per metric ton. Some of Herzog’s reasons for skepticism are highly technical and relate to the physics of separating gases. Some are more easily grasped. He points out that because direct-air-capture machines have to move tremendous amounts of air through a filter or solution to glean a ton of CO₂ — the gas, for all its global impact, makes up only about 0.04 percent of our atmosphere — the process necessitates large expenditures for energy and big equipment. What he has likewise observed, in analyzing similar industries that separate gases, suggests that translating spreadsheet projections for capturing CO₂ into real-world applications will reveal hidden costs. “I think there has been a lot of hype about this, and it’s not going to revolutionize anything,” he told me, adding that he thinks other negative-emissions technologies will prove cheaper. “At best it’s going to be a bit player.”

The machine was the first drill rig capable of drilling at an angle making it ideally suited for block drilling.  Booysen Bore was so impressed with the ROC L8’s performance that they decided to keep the machine for blast-hole drilling on the mine and to systematically replace all their non-Atlas Copco drill rigs at the end of their life cycle with ROC L8s.”

"It was not by accident that the design looks the way it does, or that it is as simple as it is, that it moves the way it does," Mattson said. "The students worked to that."
