Endogenous phospholipase D and phosphatidic acid phosphatase activities were demonstrated in membrane fractions isolated from soybean (Glycine max L.) hypocotyls. Phospholipase D activity was distributed widely among different membrane fractions while phosphatidic acid phosphatase was found predominantly in membranes equilibrating in lower sucrose densities. Phospholipase D action was unaffecte...
Glycogen phosphorylase (GP) appears as a key enzyme for the control of hyperglycemia in the context of type 2 diabetes. In order to gain additional data for structure-activity studies of the inhibition of this enzyme, a series of eight GP inhibitor candidates were prepared from peracetylglucopyranosyl azide 1 by click-chemistry. The need for a N-Boc-protected propargylamine was identified in th...
Protected area managers, tourism providers, and other organisations commonly employ education programmes to address visitation-related impairment of natural and cultural resources, social conditions, and neighbouring communities. These programmes have different names (Leave No Trace, Codes of Conduct, Environmental Guidelines for Tourists) but share common objectives: to sustain opportunities f...
We present a trifunctional scaffold designed for the solid-phase synthesis of trimodal compounds. This scaffold holds two alkyne arms in a free and TIPS-protected form for consecutive CuAAC (copper(I)-catalyzed azide-alkyne cycloaddition), one Fmoc-protected hydrazide arm for reaction with aldehydes, and one carboxylic acid arm with CF₂ groups for attachment to the resin and (19)F-NMR quantific...
When working with explosive materials, the worker’s hands are usually the most exposed body part and highly endangered by fragmentation effects. Several kinds of protective gloves are available. Existing standards describe testing procedures for the testing of protective gloves for mechanical risks, but seem to not realistically simulate fragmentation effects. An experimental setup was develope...
Under nonequilibrium conditions, bosonic modes can become dynamically unstable with an exponentially growing occupation. On the other hand, topological band structures give rise to symmetry protected midgap states. In this Letter, we investigate the interplay of instability and topology. Thereby, we establish a general relation between topology and instability under ac driving. We apply our fin...
This paper presents the research work addressing optimal secure and protected Multicasting in wired and wireless Hierarchical Sensor Networks (HSN). The multicast nodes in a hierarchical set up are associated with” Importance values” that are normalized into probabilities. The security constraint imposed is associated with the concept of “Prefix-free paths” in the associated graph. The optimali...
The dimethyl ether steam reforming reaction to generate hydrogen was tested over 1 wt % Pd/Al2O3 catalysts prepared from different precursors. The conventional catalyst prepared by incipient wetness impregnation from palladium nitrate underwent strong deactivation under reforming conditions at 823 K because of metal sintering and carbon deposition. The same occurred over the catalyst prepared f...
Preparation of microcapsules through interfacial cross-linking of soluble starch/hydroxyethyl starch and bovine serum albumin (BSA) with terephthaloyl chloride is described. The proteinase inhibitor aprotinin, either native or active site protected, was microencapsulated, being incorporated in the aqueous phase. The influence of aqueous phase pH, BSA, and terephthaloyl chloride concentrations a...
This paper provides an overview of a FAIR research project into the specific conditions and institutional requirements for the development of PDO and PGI products (Protected Designation of Origin and Protected Geographical Indication). Twenty-one supply chains in seven countries are analysed (France, Italy, Greece, Netherlands, UK, Spain and Switzerland). The primary factor in success is the ca...
