FAO News Article: Disasters take heavy toll on agri-food
Major threats. The report identifies drought as the single greatest culprit of agricultural production loss, followed by floods, storms, pests and diseases, and wildfires. Over 34 percent of crop and livestock production loss in LDCs and LMICs is traced to drought, costing the sector $37 billion overall. Drought impacts agriculture almostThe tool cutting lifetime was studied by conducting face-milling experiments, carried out in an Okuma Cadet Mate CNC vertical machining centre. The DLC- and DLC-WS 2 -coated mill inserts were used to cut an AlSi alloy material. The performance of these coatings was benchmarked to a commercial TiB 2 -coated insert.DLC and DLC-WS2 Coatings for Machining of Aluminium Alloys

Removing toxic mercury from contaminated water
The electrode is made of the noble metal platinum, and through an electrochemical process it draws the toxic mercury out of the water to form an alloy of the two. In this way, the water is cleanedThe most effective method for improving wear resistance of rapidly wearing agricultural machine components reacting under operating conditions with an abrasive soil medium is application of hard alloy coatings by surfacing. The thickness of a surfacing layer is a factor governing the operating life of these components. Production limitations exist Improving Wear Resistance of Agricultural Machine

10 Tips That Can Advance Your Welding Skills Successful
Employ a small-diameter, low-hydrogen electrode, such as a 7018 stick rod, when repairing high-strength steels, adds Leisner. Finally, keep your welding travel speed slow; this keeps the weld puddle molten by giving hydrogen gas bubbles time to boil out. The result is a better finished weld. 8.A Fox News article, titled “Climate czar John Kerry says extreme storms caused by climate change will ‘rip’ crops away and ‘destroy homes’” quotes Kerry saying that climate change is devastating crops, destroying homes, and killing people, problems that Kerry claims will only become worse in the future.

American farmers are killing their own crops and selling
Nearly three quarters of US farmers say this year’s drought is hurting their harvest with significant crop and income loss, according to a new survey by the American Farm Bureau FederationThe diffusion of tree crops has continuously increased during the last decades all over the world. The market boost has favored the adoption of intensive and highly mechanized cultivation, often triggering the degradation of the soil physical-hydrological qualities, mainly through enhanced soil erosion and compaction.
