The Seventeenth Data Release of the Sloan Digital Sky Surveys: Complete Release of MaNGA, MaStar and APOGEE-2 Data

This paper documents the seventeenth data release (DR17) from the Sloan Digital Sky Surveys; the fifth and final release from the fourth phase (SDSS-IV). DR17 contains the complete release of the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey, which reached its goal of surveying over 10,000 nearby galaxies. The complete release of the MaNGA Stellar Library (MaStar) accompanies this data, providing observations of almost 30,000 stars through the MaNGA instrument during bright time. DR17 also contains the complete release of the Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2) survey which publicly releases infra-red spectra of over 650,000 stars. The main sample from the Extended Baryon Oscillation Spectroscopic Survey (eBOSS), as well as the sub-survey Time Domain Spectroscopic Survey (TDSS) data were fully released in DR16. New single-fiber optical spectroscopy released in DR17 is from the SPectroscipic IDentification of ERosita Survey (SPIDERS) sub-survey and the eBOSS-RM program. Along with the primary data sets, DR17 includes 25 new or updated Value Added Catalogs (VACs). This paper concludes the release of SDSS-IV survey data. SDSS continues into its fifth phase with observations already underway for the Milky Way Mapper (MWM), Local Volume Mapper (LVM) and Black Hole Mapper (BHM) surveys

Liquid-liquid extraction of cobalt(II) and manganese(II) with bis(2,4,4-trimethylpentyl)monothiophosphinic acid (Cyanex 302)

Cobalt(II) was quantitatively extracted at pH 7.0-7.5 in the presence of 1.0 M ammonium sulphate with 7.5 x 10-3M Cyanex 302 while the extraction of manganese(II) was quantitatives at pH 8.5-9.5 in the presence of 0.1 M ammonium sulphate with 5 x 10-3M Cyanex 302. Cobalt(II) from the organic phase was stripped with 1.0 M hydrochloric acid while manganese(II)was stripped with 1.0 M sulphuric acid. Both metals were separated from complex mixtures of several metals. These methods were extended for the determination of cobalt and manganese in real samples.</span

ACL Reconstruction Recovery Rates Trend Lower for Athletes with Additional Knee Damage

Currently, the standard Return to Play (RTP) metrics do not encapsulate the competitive level to which an athlete returns post-injury. This study examines the characteristics and performance of male Tier 4 and higher soccer players, and their ability to RTP following both isolated anterior cruciate ligament (ACL) injuries and ACL injuries with additional structural damage to the knee. Results indicate that the rate of return to Tier 4 leagues or higher trends lower for athletes with Grade 3 or higher chondral lesions or meniscal pathologies
