Romance is dead, proposes author Nancy Jo Sales, in the September issue of the publication. What sets Tinder apart from most other dating app or online dating experiences is speed and brevity. Based on a photo, first name, and age alone, users decide whether to swipe left to pass or right to like. With GPS tracking, the app also tells users exactly how far away potential matches may be, making life even easier for those just looking for a quick hook-up. Shallowest dating app ever? The biggest criticism of Tinder? It’s a seriously shallow app that turns people into quickly-judged commodities on a screen.

Lutetium–hafnium dating – Wikipedia

Advanced Search Abstract The Junggar ocean, once situated north present coordinate of the Yili and Central Tianshan blocks during early Paleozoic to late Carboniferous time, was a major southern branch of the Paleo—Asian Ocean, the opening, expansion, and final closure of which led to the development of the Central Asian Orogenic Belt between Eastern Europe—Siberia and Tarim—North China. However, the detailed evolution of the Junggar ocean has not been well constrained. This paper reports U-Pb and Lu-Hf isotopic data of detrital zircons from sandstones in the North Tianshan belt, which can provide new insights into understanding the Paleozoic development of the Junggar ocean.

The predominant Paleozoic zircons yield major age populations at ca. The minor Precambrian zircons yield ages scattering at ca.

Geography and Geology, University of Salzburg, Hellbrunnerstr. Our new data constrain the eastern extension of the Erenhot-Hegenshan suture zone and the plate collision processes between the northern margin of the North China craton and the composite Erguna-Hinggan-Songliao block. The U-Pb ages of detrital zircons indicate ages as young as Late Permian to Early Triassic indicating a younger depositional age as previously assumed.

The younger, — Ma age group is interpreted to derive from a post-orogenic A-type granitoid belt. Synthesizing this unique information on a magmatic arc of an approximate age of Ma we define a distribution of the Sonidzuoqi—Xilinhot magmatic arc as follows. The arc extends from Solon Obo via Sonidzuoqi, Xilinhot through Ulanhot to Qiqihar, and then it is cut by the sinistral Nenjiang-Balihan slip-strike fault western boundary fault of the Songliao basin , and ultimately extends to Longzhen in the northern sectors of the Da Hinggan Mountains.

The Erenhot-Hegenshan suture zone is located north of this magmatic arc. Therefore, the collision between the North China craton and the Hinggan-Erguna block started during the deposition of the Linxi Formation and the final closure of the intervening oceanic basin occurred during Late Permian-Early Triassic forming the Ondor Sum-Xar Moron suture zone.

Lu hf dating hafnium is a chemical element with interracial dating in ghana symbol hf and atomic number A lustrous, silvery scam dating in ghana gray, tetravalent transition metal, lu hf dating hafnium chemically resembles.

Physical characteristics[ edit ] Pieces of hafnium Hafnium is a shiny, silvery, ductile metal that is corrosion -resistant and chemically similar to zirconium [6] due to its having the same number of valence electrons , being in the same group, but also to relativistic effects ; the expected expansion of atomic radii from period 5 to 6 is almost exactly cancelled out by the lanthanide contraction.

The physical properties of hafnium metal samples are markedly affected by zirconium impurities, especially the nuclear properties, as these two elements are among the most difficult to separate because of their chemical similarity. The most notable nuclear properties of hafnium are its high thermal neutron-capture cross-section and that the nuclei of several different hafnium isotopes readily absorb two or more neutrons apiece.

Hafnium dioxide Hafnium reacts in air to form a protective film that inhibits further corrosion. The metal is not readily attacked by acids but can be oxidized with halogens or it can be burnt in air. Like its sister metal zirconium, finely divided hafnium can ignite spontaneously in air. The metal is resistant to concentrated alkalis. The chemistry of hafnium and zirconium is so similar that the two cannot be separated on the basis of differing chemical reactions. The melting points and boiling points of the compounds and the solubility in solvents are the major differences in the chemistry of these twin elements.

Isotopes of hafnium At least 34 isotopes of hafnium have been observed, ranging in mass number from to

Non-“Metal Gear Saga” information ends here. Unconfirmed history The following information has been detailed in official Konami -licensed media, written by various external authors. Its status in the Metal Gear canon is unconfirmed. It was an enhanced replica of an 8th century Chokuto sword fashioned for the Emperor Shomu; the original weapon was stolen from the imperial repository in Nara sometime in These swords have no curvature and were originally fashioned in a wood-grain pattern.

It’s a usable weapon in Metal Gear Solid: Integral , during the Ninja VR Missions. It also appears in the remake The Twin Snakes under the same role. Due to directoral decisions for cutscenes, Gray Fox also briefly uses it to damage the radome by impaling it, also shooting it out upon causing irreparable damage to the radome. Snake also briefly picks up the HF blade and wields it before slamming it down onto the ground.

After owning it for a while, I see there is still very little information out there about it. So I thought I’d provide a little more for people to read, at least with respect to weak signal reception. Others can comment on the ham-friendly menu options, and the transmission capabilities, such as direct access to the CW keyer on the front panel, ESSB, etc. I also used the same headphone set, plugged into one receiver, and then the other, so that the speakers used in each radio would not be part of the equation.

The tests were conducted both during the day, and at night, over several days. When comparing the Sienna to the K3S, it was not much of a contest. The filtering in the K3S is mostly done in software, whereas the Sienna uses mainly analog filters. My Sienna is fully loaded with Collins filters, and I rely on the twin-passband tuning to provide clarity. The K3S has a whole raft of digital tricks to process the signal and get rid of noise, but in the end, the output is harsh.

There is an edginess to the K3S received signal that is hard on the ears.
