Chiral pyrrolidines and pyrrolizidines with spirooxindole ring systems are the central skeletons for numerous alkaloids and pharmacologically important compounds. Gelesmine, pseudotabersonine, formosanine, isoformosanine, morroniside and mitraphylline are some of the alkaloids containing spirooxindole ring systems. Derivatives of spirooxindole find very wide biological applications as anti micr...

Stormwater runoff is an issue that increasingly affecting urban areas because previously were permeable have been developed, and are now impermeable, comprising hard surface areas, whether concrete floors, roads, or buildings. As the size of problem area increases, amount stormwater needs to be cleared from it takes longer for cleared. The existing basic public drainage systems can no sufficien...

Asynchronous packet-switched interconnection networks with decentralized control are very appropriate for multiprocessing and data flow architectures. This paper presents performance models of single and multiple ring networks based on token ring, slotted ring, and register insertion ring protocols. The multiple ring networks have the advantages of being reliable, expandable, and cost effective...

The vertical change in the number of macropores causes a variation relative macroporosity (wf) and effective aggregate width (dag) over soil profile. Both parameters are used HYDRUS to represent this variation, increasing making automated calibration challenging. working hypothesis is that we can improve an analytical estimation wf dag developed previous research by inverse with meta-model for ...

Examining the fine-scale spatial structure of fungal populations can tell us much about how individual species reproduce and disperse throughout natural landscapes. Here we study the fine-scale genetic structure of Tricholoma matsutake, a prized edible and medicinal mushroom, by systematic sampling of mycorrhizas within fairy rings in 50-y-old and old-growth forests in two villages. Using singl...
