The title thia-calix[4]arene derivative, C(36)H(34)Br(2)O(8)S(4), adopts an unusual pinched cone conformation with the prop-oxy-substituted benzene rings inclined inward [forming a dihedral angle of 33.4 (1)°] and with the brominated benzene rings bent outward, making a dihedral angle of 66.1 (1)°. In the crystal, the mol-ecules form chains along [001] via C-H⋯S hydrogen bonds and S⋯S contacts ...

We show that there exists a Lie a bracket on the cohomology of any type of (bi)algebras over an operad or a prop, induced by an L∞-structure on the defining cochain complex, such that the associated L∞-master equation captures deformations. This in particular implies the existence of a Lie bracket on the Gerstenhaber-Schack cohomology [7] of a bialgebra that extends the classical intrinsic brac...

The type material of Epeorellaborneonia Ulmer, 1939, the sole species of the genus Epeorella Ulmer, 1939 is reinvestigated and a lectotype (male imago) is designated. Based on several morphological structures, the synonymy with Epeorus Eaton, 1881 (Rhithrogeninae) is rejected. Epeorella stat. prop., known only at the winged stages, belongs to the subfamily Ecdyonurinae, and is a probable endemi...

A tandem organosolv pulping and Pd-catalysed transfer hydrogenolysis depolymerisation and deoxygenation has been developed. The tandem process generated 2-methoxy-4-(prop-1-enyl)phenol in 23% yield (92% theoretical monomer yield) starting from pine wood and 2,6-dimethoxy-4-(prop-1-enyl)phenol in 49% yield (92% theoretical monomer yield) starting from birch wood. Only endogenous hydrogen from wo...

Trehalose synthesis (RpoS-dependent) and betaine uptake mediated by transporters ProP and ProU contribute to the osmotolerance of Escherichia coli K-12. Pyelonephritis isolates CFT073 and HU734 were similar and diminished in osmotolerance, respectively, compared to E. coli K-12. The roles of RpoS, ProP and ProU in osmoregulation and urovirulence were assessed for these isolates. Strain HU734 ex...

Taste sensitivity to the bitter compound 6-n-propylthiouracil (PROP) is considered a marker for individual differences in taste perception that may influence food preferences and eating behavior, and thereby energy metabolism. This review describes genetic factors that may contribute to PROP sensitivity including: (1) the variants of the TAS2R38 bitter receptor with their different affinities f...

The Propagation Rule Compiler (PROP) is a tool developed within task 2.4 \Tools for Rule Design and Analysis". It aims at supporting developers of Chimera applications during schema design and prototyping. PROP consists of two components: the rule compiler as such and an explanation facility. The task of the explanation facility is to graphically illustrate the logical dependencies established ...

This paper illustrates the role of a class of \prop"-ositional logic programs in the analysis of complex properties of logic programs. Analyses are performed by abstracting Prolog programs to corresponding \prop"-ositional logic programs which approximate the original programs and have nite meanings. We focus on a groundness analysis which is equivalent to that obtained by abstract interpretati...

Enterprise Architecture (EA) is becoming an increasingly mature field of work, but many large organizations still struggle with implementing an integral and truly effective EA function. The literature provides a fragmented picture of the EA function, describing the various separate elements that make up the total package of activities, resources, skills, and competences of the EA delivery funct...
