The title compound, C(26)H(28)N(2)O(9)·1.5H(2)O, the product of an acid-catalysed Wagner-Meerwein skeletal rearrangement, crystallizes as a sesquihydrate with the O atom of one of the two independent water mol-ecules occupying a special position on a twofold axis. The organic mol-ecule comprises a fused penta-cyclic system containing two five-membered rings (cyclo-pentane and tetra-hydro-furan)...

The mol-ecular structure of the title compound, NH(4) (+)·C(7)H(7)O(4)S(-), is featureless [the methoxy C atom deviating 0.173 (6) Å from the phenyl mean plane] with inter-atomic distances and angles in the expected ranges. The main feature of inter-est is the packing mode. Hydro-philic (SO(3) and NH(4)) and hydro-phobic (PhOCH(3)) parts in the structure segregate, the former inter-acting throu...

Mathematical models for the electricity portfolio management of a utility that owns a hydro-thermal generation system and trades on the power market often lead to complex stochastic optimization problems. We present a new approach to solving stochastic hydro-storage subproblems that occur when stochastic Lagrangian relaxation is applied to solving such models. The special structure of such hydr...

In the title compound, C(25)H(25)N(3)O(4), the central pyrrolidine ring and the two pyrrolidine rings adopt twisted conformations, whereas the piperidine ring in the octa-hydro-indolizine fused ring system adopts a chair conformation. The indoline ring systems are almost perpendicular with respect to the mean plane of the octa-hydro-indolizine ring system, making dihedral angles of 84.4 (5) and...

Soil moisture influences and is influenced by water, climate, and ecosystem conditions, affecting associated ecosystem services in the landscape. This paper couples snow storage-melting dynamics with an analytical modeling approach to screening basin-scale, long-term soil moisture variability and change in a changing climate. This coupling enables assessment of both spatial differences and temp...

Defining valid enterprise-wide roles needs to be carried out on the basis of a predefined Role Development Methodology. Hybrid role development combining elements from Role Engineering and Role Mining is the most promising way to define enterprise-wide roles, however no such model has been published yet. We close this gap by analysing existing approaches and proposing HyDRo, a tool-supported me...

Recent advances in development of semiconductor devices lead to more and more complex device structures. This concerns device geometry as well as tne combination of different materials. Due to the rapid reduction of device geometries, the models describing the device physics increase in complexity. 10 gain additional insight into the performance of devices under realistic dynamic boundary condi...

The title protein has been crystallized in a new crystal form. The crystals belong to the cubic space group P4132 (or P4332) with unit-cell dimensions a = b = c = 126.1 A at 100 K and typically diffract beyond 1.6 A at the Cornell High Energy Synchotron Source (CHESS) A1 beamline.

Seed germination is the initial step of plant development. Seed priming with salt promotes seed germination in tomato (Solanum lycopersicum L.); however, the molecular and physiological mechanisms underlying the enhancement of seed germination by priming remain to be elucidated. In this study, we examined the following in seeds both during and after priming treatment: the endogenous abscisic ac...
