Temperature-dependent thermal expansivities of silicate melts: The system anorthite-diopside [PDF]
, 1992 The temperature-dependent thermal expansivities of melts along the join anorthite-diopside have been determined on glassy and liquid samples using a combination of calorimetry, dilatometry, and Pt double bob Archimedean densitometry.

The newfound relationship between extrachromosomal DNAs and excised signal circles
FEBS Letters, EarlyView.Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Liquid-liquid extraction of cerium using synergist extractant
Journal of Mechanical Engineering and Sciences, 2018 This work studies on the performance of synergist extractants on the extraction of Cerium (Ce) alone. Conventional extractant, 4,4,4-trifluoro-1-(2-thienyl)-1,3- butanedione (HTTA) was combined with 3-methylimidazolium bis(triflouromethylsulfonyl)imide [

FEBS Letters, EarlyView.This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Crossflow Filtration of Sodium Chloride Solution by A Polymeric Nanofilter: Minimization of Concentration Polarization by a Novel Backpulsing Method [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 2016 In the present study, the production of low-salt water from salty water by nanofiltration as well as membrane fouling was investigated. Furthermore, a new method was proposed and tested experimentally for creating the backpulse in order to minimization ...
