Inverted Fates and Inverted Texts. Rationales of Reinterpretation in the Compositional History of the Isaianic Prophecies, with Special Emphasis on Isaiah 10,16–19 and Its Context
This study argues that Isa 10,16–19, located in the context of the anti-Assyrian prophecy, provides essential clues in understanding the formation of the book of Isaiah. While current research often takes this text as a late redactional composition, it is more reasonable to argue that the pericope was relocated by the editors from a prophecy originally threatening Israel with destruction. This level of meaning is endorsed by the specific metaphors

Asthma and wheezing disorders are common chronic health problems in childhood. Breastfeeding provides health benefits, but it is not known whether or how breastfeeding decreases the risk of developing asthma. We performed a systematic review and meta-analysis of studies published between 1983 and 2012 on breastfeeding and asthma in children from the general population. We searched the PubMed and Embase databases for cohort, cross-sectional, and case-control

Metallic glasses (MGs) look like metals and have the intimate structure and sometimes the behavior of glasses. The first reported scientifically obtained MG was the alloy Au75Si25 produced at Caltech by Klement et al., in 1959, by extremely rapid cooling of the Au-based melted alloy. Due to the high solidification rate required to produce MGs, the section thickness was small, i.e. only a few tens of micrometers, typically 20 to 50m [5-7].

Highlights FeSiBAlNi (C, Ce) amorphous HEAs have been fabricated by mechanical alloying. The effects of C and Ce addition were investigated. Ce addition exhibits a remarkably enhanced effect on glass forming ability (GFA). C and Ce additions are beneficial to enhance thermal stability. http://www.sciencedirect.com/science/article/pii/S0304885316303894

ABSTRACT: Purpose of the paper was the optimization of mobile phase in natrium chloride gradient in the chromatographic separation of butyrylcholinesterase from human plasma. Materials/Methods. Butyrylcholinesterase (BuChE) was isolated from human plasma using a diethylamminoethyl-cellulose column, by elution with 0.02M acetate buffer pH=4.0, gradually increasing NaCl percentage from 10% to 80%. The procedure lasted approximately 28 days. Results.

Abstract The objectives of this study were to develop and validate a method for the simultaneous HPLC-UV determination of obidoxime (OBI), scopolamine (SCA), Atropine (ATR) and imipramine (I) in an aqueous antidote solution. An ion-pair mechanism with DAD (diode array detector) detection was used to quantitatively determine the four drugs. The proposed HPLC method uses a Kromasil 100-5C8 (250x4.6mm) column, gradient elution, at 25°C column temperature.
