Abstract. We analyzed air samples collected on board a C-130 cargo aircraft over the western North Pacific from May 2012 to March 2020 for atmospheric δ(O2 / N2) and CO2 amount fraction. Observations were corrected significant artificial fractionation of O2 N2 caused by thermal diffusion during sample collection using simultaneously measured δ(Ar N2). The observed seasonal cycles potential oxyg...

In order to understand the quality of radiation environment in near surface air Mianyang area, grasp trend its change, explore sources aerosol substances and their significance tracking concentration O3 ground, a detailed gamma spectrum analysis samples from March 2018 February 2019 Anzhou District, Jiangyou City, Zitong County Pingwu was carried out. general, activity 7</s...

A cyclic AMP-binding protein with a native molecular weight calculated to be 82,000 was purified 2,000-fold from Neurospora crassa. The apparent subunit molecular weight was 47,000 by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, suggesting that the native protein exists as a dimer of identically sized subunits. The 8-N3-cyclic [32P]AMP-labeled protein appeared as a doublet upon tw...

Cyclic di-AMP is a recently discovered signaling molecule which regulates various aspects of bacterial physiology and virulence. Here we report the characterization of c-di-AMP synthesizing and hydrolyzing proteins from Mycobacterium tuberculosis. Recombinant Rv3586 (MtbDisA) can synthesize c-di-AMP from ATP through the diadenylate cyclase activity. Detailed biochemical characterization of the ...

Phytocompounds of natural origin are not only a potential source for maintaining human health but also the supplement nutrients long period survival. In recent years, essential oils and herbal extracts have attracted great scientific interest due to its as antioxidants biologically active compounds, especially in last decade with more intensive studies chemotherapies antioxidant activity. The m...

Following works of Furstenberg and Nevo and Zimmer we present an outline of a theory of stationary (or m-stationary) dynamical systems for a general acting group G equipped with a probability measure m. Our purpose is two-fold: First to suggest a more abstract line of development, including a simple structure theory. Second, to point out some interesting applications; one of these is a Szemeréd...

Total hip arthroplasty through a single-incision anterior approach is a minimally invasive surgical (MIS) technique that allows component placement without violation of the posterior hip capsule or "hip deltoid." This allows faster recovery without dislocation precautions. The Fitmore® hip stem (Zimmer, Warsaw, Ind) is a bone-conserving stem designed for use in MIS techniques. The technique des...
