Water pumped from the Dhuleil - Halabot aquifer was initially of good quality with ECw in the range of 0.4 to 0.6 dS/m. In the northeastern part of the project lower quality water was found with ECw ranging between 1.05 and 1.35 dS/m. Since irrigation began in 1971 there has been a slow deterioration in water quality.

The photochemistry and photocytotoxicity of half-sandwich Os-arene complexes have been investigated by experimental and theoretical methods. Os-arene χurcumin complexes exhibit high potency and selective phototoxicity toward a range of cancer cell lines, especially toward cisplatin-resistant cancer cell lines, but are relatively nontoxic to normal cells. …

Oligocene (gold at Round Mountain and Jefferson), and Miocene (gold at Manhattan). Most likely principal sources of molybdenum, tungsten, silver, and bismuth are Cretaceous granites; of antimony, arsenic, and mercury are intermediate-composition early Oligocene intrusives; and of gold are early and late Oligocene and early Miocene magmas of the

Neal Moore was weeks into a cross country paddle when the Covid-19 pandemic hit. After discussing with trusted friends and colleagues, he determined that with the canoe as his only home, sheltering in place meant continuing the journey. Here is a selection of his stories: A Spartan Life Brian Bensen stands astride his makeshift home…

Molybdenum is a chemical element with the symbol Mo and atomic number 42. The name is from Neo-Latin molybdaenum, from Ancient Greek Μόλυβδος molybdos, meaning lead, since its ores were confused with lead ores.Molybdenum minerals have been known throughout history, but the element was discovered in 1778 by Carl Wilhelm Scheele.

Molybdenum properties. When added to steel and cast irons, molybdenum enhances strength, hardenability, weldability, toughness, elevated temperature strength, and corrosion resistance. In nickel-base alloys, it improves resistance to both corrosion and high-temperature creep deformation. Molybdenum-based alloys have a unique combination of ...

Whether it is filing a mine or researching one, the administering BLM office is going to be the definitive source. Mine handled by the Bureau of Land Management are not mapped by latitude and longitude, instead, these mines harken back to the Public Land Survey System. A "township" can refer to two different things.

Tungsten belongs to the group of metals with a high melting point (also called refractory metals). Refractory metals are metals that have a higher melting point than platinum (1772 °C). In refractory metals, the binding energy between the individual atoms is particularly high.
