Gfpg Discrepancies in the Hubble Constant Have Vexed Astronomers 鈥?NASA s Roman Space Telescope Could Help Resolve the Puzzle
An international collaboration led by scientists from the University of Hong Kong, RIKEN (Japan), and CEA (France) have used the RI Beam Factory (RIBF) at the RIKEN Nishina Center for Accelerator-base Science to show that 34 is a ldquo magic number rdquo for neutrons, meaning that atomic nuclei with 34 neutrons are more stable than would normally be expected. Earlier experiments had suggested, but not clearly demonstrated, that this would be the case.The experiments, published in Physical Review Letters, were performed using calcium 54, an unstable nucleus which has 20 protons and 34 neutrons. Through the experiments, the researchers showed that it exhibits strong shell closure, a situation with neutrons that is similar to the way that atoms with closed electron shells, such as helium and neon, are chemically inactive. While it was once believed that th adidas campus homme e p stanley bicchieri rotons and neutrons were lumped together like a soup within the nucleus, it is now known that they are organized ugg mini in shells.

NEC launches new MC series projectors designed for classroom and office useIf you rsquo re shopping for new portable projectors for classroo nike air max 1 m or mid-sized meeting room use, NEC Asia Pacific has just announced five new models from its MC series. Lamp-based and using LCD tech, the asics gel kayano se new projectors aim to satisfy users who are cost-conscious but yet demand high functionality from their projectors.The new MC series projectors are:MC301X - 3,000 lumens, XGAMC331X - 3,300 lumens, XGAMC331W - 3,300 lumens, WXGAMC371X - 3,700 lumens, XGAMC421X - 4,200 lumens, XGASince NEC expects the MC series projectors to be used mainly in schools and offices, it has equipped air max donna them with features such fast startup (6 seconds), auto power on/off, and automatic keystone correction. Also, direct wireless connectivity is offered through an integrated Simple Access Point function, which enables multiple devices to connect to the projector without the need for an additional router.
