CHEMICAL ABUNDANCES IN NGC 5024 (M53): A MOSTLY FIRST GENERATION GLOBULAR CLUSTER
Astrophysical Journal, 2016 ABSTRACT We present the Fe, Ca, Ti, Ni, Ba, Na, and O abundances for a sample of 53 red giant branch stars in the globular cluster (GC) NGC 5024 (M53). The abundances were measured from high signal-to-noise medium resolution spectra collected with the Hydra multi-object spectrograph on the Wisconsin–Indiana–Yale–NOAO 3.5 m telescope. M53

A multiband photometric study of RR Lyrae stars in M53 (NGC 5024)
New AstronomyWe present a multiband (UBVRI) time-series photometric study of RR Lyrae (RRL) stars in the globular cluster Messier 53 (NGC 5024) to refine their pulsation properties and determine a precise cluster distance. The archival photometric data includes images taken over 22 years and 3 months using different optical telescopes, providing an excellent time ...

CCD Photometry of the Globular Cluster M53. I. Color-Magnitude Data and Blue Straggler Stars
Astronomical Journal, 1998 The first large-format CCD color-magnitude diagram (CMD) in the B and V passbands is presented for the Galactic globular cluster M53 (NGC 5024). The observations consist of 40 pairs of B and V CCD frames with FWHM < 12 in a pattern covering a 12' × 13' region of M53. These frames were used to produce color-magnitude data for more than 20,000 stars from

Powdery mildew disease caused by Blumeria graminis f. sp. tritici (Bgt) is an economically important disease in wheat worldwide. The identification of germplasms resistant to the disease can not only facilitate the breeding of resistant cultivars, but can also broaden the diversity of resistance genes.

Abstract Waste cooking oil (WCO), an oil-based substance that is produced from cooking, causes heavy burden to the environment and society. The coproduction of erythritol and lipase by Yarrowia lipolytica from this low-cost fatty matter was evaluated in this study.
