Ancient Sumerians in southern Mesopotamia dug canals. More than 4,000 years ago Egyptian farmers relied on the Nile—traces of their irrigation systems survive today. Throughout the Roman Empire cities were supplied by manmade aqueducts. High in the Andes in present-day Peru the Incas and their predecessors built cisterns and irrigation canals, and carved terraces into the hillsides.

2015 Topps Football represents the brand’s 60th anniversary. While the main design and majority of the content is unmistakably modern, there are several nods to the past to go with them.

While MC protects against numerous conditions and infections, in the case of HIV, in locations where HIV prevalence is high and MC rates are low, increasing adult MC should be regarded as an urgent objective, while increasing infant MC should be an important objective. In populations where HIV prevalence is still low and MC rates are low, increasing infant MC should be a priority.

Half of all group revenues came from Europe, Middle East and Asia (EMEA) with the Americas representing Mincon’s second most significant market, accounting for 29 per ent of turnover. Revenues in the company’s Australasia division rose from 17 per cent of group turnover to 22 per cent last year.

Off camera, Vanessa is as driven and accomplished as she appears to be when leading her crew onscreen. She has a passion for riding horses and running long distance relay races, and she developed a successful children’s toy company.

By: Creamer Media Reporter    Updated 43 minutes ago Vapor Wake K9 SA will be showcasing the Vapor Wake method of training working dogs in the detection of explosives and other illicit substances – the first organisation outside the US to offer this advanced type of canine technology – as the official sponsor of the Vapor Wake K9 SA demo area at the upcoming Securex South Africa 2019 expo. Securex, which is Africa’s leading security and fire trade exhibition, takes place from 14 to 16 May this year at Gallagher Convention Centre in Midrand, Johannesburg. →

†NNT number needed to treat – i.e., approximate number of males who need to be circumcised to prevent one case of each condition associated with lack of circumcision.

The group’s board has recommended is recommending the payment of a final dividend for the year of 1 cent per ordinary share.

Borehole or down-hole methods are of two distinct varieties: borehole seismic and wireline logging. The former is achieved when seismic receivers are used to acquire information in the borehole, presented as a vertical seismic profile (VSP).  VSP in most cases, is integrated with surface seismic information. A successful example of this method is the use for mine planning, and harnessing deposits of uranium in northern Saskatchewan, Canada. Conversely, the latter is when a logging tool called ‘sonde’ is used in the vicinity of the borehole. The information obtained are presented as Logs; a plot of the measured physical property versus depth. In a basic sense, well logs help to identify and quantify minerals.

Ity is expected to produce 160- 200koz in 2019 at an AISC of $525- 590/oz, with the bottom-end of production guidance corresponding to the nameplate capacity while the top-end factors in possible upsides from an earlier start date, a quicker than expected ramp-up and the plant producing above its nameplate.

A sound understanding of borehole design and construction and the hydrogeology of the site, followed by routine monitoring and maintenance, is usually all that is required to ensure continued service and sustained performance.

Support for this project originally came from MIT Energy Initiative (MITEI), which in 2008 provided seed money and later a follow-up grant. Although Woskov continues to pursue ways his technology can advance geothermal energy research, his current support is from the Department of Energy’s Office of Nuclear Science, through Impact Technologies LLC, which funds him to explore deep bore hole storage of radioactive and nuclear wastes. At 6 km deep, such bore holes would place waste much farther from the biosphere than is possible with near-earth depositories such as Yucca Mountain. The bottom 2 kilometers of the hole would hold waste, capped with a 2-km seal — which is currently considered the “weak link” in the process. Woskov is experimenting with melted basalt and the more viscous granite to learn how he can seal the holes with melted rock, which could provide the most secure entombment of the waste products.
