GCL-Poly

GCL-Poly (SEHK: 3800), founded in 1996, was originally a China Poly Group 's companies, is a green energy supplier in China, providing power and heat via cogeneration, incineration and wind power. As of 2009 it was the largest supplier of polysilicon in China, and is also a supplier of electronic wafers for the solar industry.

GCL-Poly in 2007 at the Hong Kong Stock Exchange listing, the IPO price range was 3.3 to HK $4.1, raising up to 1.181 billion yuan.

In November 2009, China Investment Corporation (CIC) bought a HK$5.5 billion ($710 million) minority stake in GCL-Poly.

February 14, 2014 GCL-Poly implement Subscription Rosenthal Group 360,000,000 new shares at a price of four yuan per share, a discount of 70.37% compared with before the suspension. The total cost of 1.44 billion yuan in cash. Upon completion, GCL will hold 67.99 percent after Rosenthal enlarged share capital.

November 2014, GCL-Poly plans a total consideration of 10.1 billion yuan to Zhu Gong Shan and its connected investors to sell about half of the company's profit contribution Xipian manufacturing operations. After Zhu Gong Shan plan then silicon chipalso production business into Shanghai Super Day, and GCL-Poly will shift its focus to upstream polysilicon business. December 19 the same year, GCL-Poly announced the cancellation of the transaction.

GCl 38

GCl 38 is a globular cluster located in the constellation Hercules. It was discovered in 1958 by Sidney van den Bergh and Halton Arp during inspection of the photographic plates from the Palomar Sky Survey. This is a round, diffuse cluster located in the outer halo of the Milky Way galaxy. It is about 3–4 billion years younger than a typical galactic cluster.

The metallicity of the cluster is [Fe/H] = −1.50, indicating a lower abundance of elements with mass greater that helium compared to the Sun. The combined mass of the main sequence stars in the cluster is 1340 ± 50 solar masses, and the combined mass of observed stars within the half-light radius is 6020 ± 50 solar masses. (This is the inner radius of the cluster that emits half the total luminosity.) These mass estimates provide lower bounds for determining the total mass of the cluster. The median radial velocity of stars within the cluster is 72.19 ± 0.18 km/s.

Because of the cluster's location on the outer fringes of the Milky Way, it was used as a test case for modified newtonian dynamics (MOND). This is an alternative hypothesis to explain the galactic rotation problem.
