Since the Anthropocene, biodiversity loss owing to human activity and climate change has worsened. Quercus gilva is an evergreen oak species native China, Japan, South Korea threatened by a long history of impact. The purpose this study was (1) reassess category Q. based on detailed survey, (2) identify genetic structure diversity genomic data. First, we conducted survey populations in China. S...
We present the results from an automated search for damped Lyα (DLA) systems in the quasar spectra of Data Release 1 from the Sloan Digital Sky Survey (SDSS-DR1). At z ≈ 2.5, this homogeneous dataset has greater statistical significance than the previous two decades of research. We derive a statistical sample of 71 damped Lyα systems (> 50 previously unpublished) at z > 2.1 and measure H I colu...
The Cosmic Lens All-Sky Survey (CLASS), is an international (USA, UK and Netherlands) collaborative program aimed at obtaining high-resolution radio images of over 10000 at-spectrum radio sources in order to create the largest and best studied statistical sample of radio-loud gravitationally lensed systems. With this survey, combined with detailed studies of the lenses found therein, powerful c...
BACKGROUND To date there has been no population-based survey of the major risk factors for non-communicable diseases (NCD) in Uganda. Hospital-based data from urban centres report an increasing burden of NCDs in Uganda. This population-based survey aimed to describe the prevalence of risk factors for NCDs in a rural Ugandan district. METHODS The survey was conducted using the WHO STEPwise app...

At z ≈ 2.5, this homogeneous dataset exceeds the statistical significance of the previous two decades of research.

in this paper, a multi-objective method is used to optimize a heat recovery steam generator (hrsg). two objective functions have been used in the optimization, which are irreversibility and hrsg equivalent volume. the former expresses the exergetic efficiency and the latter demonstrates the cost of the hrsg. decision variables are geometric and operational parameters of the hrsg. the results of...
This Data in Brief contains results from three different survey logistic regression models comparing risks of self-reported diagnoses of cardiovascular and pulmonary diseases among smokers of menthol and non-menthol cigarettes. Analyses employ data from National Health and Nutrition Examination Survey (NHANES) cycles administered between 1999 and 2012, combined and in subsets. Raw data may be d...
