German-Jewish historian and folklorist Abraham Tendlau published this feuilleton in a supplement to “Der Israelit”, an orthodox newspaper based in Mainz. It includes summaries and long quotations (combining transliteration and translation) of the Yiddish-language “diary” of Glikl bas Judah Leib, whose writing appears here for the first time in print.
Translation from Yiddish with Introduction.
Microbial, algal, plant and animal cells have been immobilized, with preserved viability, by entrapment in various matrices according to a new bead polymerization technique. The cell polymer/monomer mixture is kept suspended in a hydrophobic phase such as soy, paraffin, or silicon oil, tri-n-butylphosphate, or dibutyphtalate, which is compatible with the cells. The various monomers or polymers tes
Horse liver alcohol dehydrogenase was immobilized on glycerylpropyl-silica (10 μm, 1000-Å pores) activated with 2,2,2-trifluoroethanesulfonyl chloride (tresyl chloride). The coupling and activity yield was almost 100%. The coenzyme-binding sites were equivalent and virtually unaffected by the immobilization process, as judged from Scatchard plots and active-site titrations. The silica-bound enzyme
This is an explorative and, at times, tentative text on the potential meanings and uses of the concept Existential Sustainability in social work and social work research. The overall argument is that to create a positive change in the lives of people in general, service users more specifically, and to sustain such change over time, it is necessary to acknowledge an existential dimension and existeThis is an explorative and, at times, tentative text on the potential meanings and uses of the concept Existential Sustainability in social work and social work research.

Magnetic calcium alginate yeast beads, made by incorporation of magnetite or colloidal magnetic liquid, FerrofluidTM, exhibited catalytic behavior similar to that of their nonmagnetic counterparts. The magnetic immobilized preparations’ shortterm performance, long-term operational stability, and capacity forin situ activation were unaffected by the inclusion of magnetic material. The magnetic qual
Concanavalin A was covalently bound to porous silica (100-1000 Å) by three different coupling procedures. The performance of the preparations was evaluated from their ability to resolve a mixture of closely related sugars. The Concanavalin A-silica was used for efficient and rapid (5-20 min) analysis/purification of samples containing the glucoproteins peroxidase and glucose oxidase. Such columns
Lactate dehydrogenase has been purified by precipitation with a bis-ligand. The precipitating agent in this case was Bis-NAD. This approach of affinity precipitation is also applicable to other enzymes.
The reactive triazine dye, Cibacron Blue F3G-A, has been covalently attached to microparticulate porous silica and used for the resolution of a number of complementary proteins by high-performance liquid affinity chromatography (HPLAC). Cibacron Blue F3G-A was converted to its 6-aminohexyl derivative by reaction with 1,6-diaminohexane and coupled to γ-glycidoxypropyltrimethoxysilane-activated poro
Three methods were developed for preparing alginate gels containing cells that are stable in phosphate containing media. In Method I preformed alginate beads containing entrapped cells were treated with polyethyl eneimine followed by glutaraldehyde. In Method II alginate sol was treated with a carbodiimide and N-hydroxysuccinimide (to form active esters), mixed with cells and extruded into calcium
I denna master class går forskarna igenom huvudpoängerna i den pupulärvetenskapliga rapporten Framtidens möten.Projektet handlar om nya modeller för affärer, interaktion och kommunikation inom mötesindustrin. Forskarna har undersökt hur pandemin påverkat mötesindustrin och om krisen fört med sig nya möjligheter. De har också studerat hur gäster i fysiska, hybrida och digitala möten och konferenser
