Spectro-gasometric ground-based measurements were carried out during 2020-2021. It was determined that five vegetation indices - REP (Red Edge Position), Green NRDI (Normalized Difference Vegetation Index), MOD (Green Model) and Red edge are more responsive to the presence of СО2 concentration depending on leaf photosynthesis respiration coastal sedge (Carex riparia) with high correlation under...

Given a set S of n red and blue points in the plane, a planar bichromatic minimum spanning tree is the shortest possible spanning tree of S, such that every edge connects a red and a blue point, and no two edges intersect. Computing this tree is NP-hard in general. We present an O(n) time algorithm for the special case when all points are in convex position. For the general case, we present a f...

The transition from endosymbiont to organelle in eukaryotic cells involves the transfer of significant numbers of genes to the host genomes, a process known as endosymbiotic gene transfer (EGT). In the case of plastid organelles, EGTs have been shown to leave a footprint in the nuclear genome that can be indicative of ancient photosynthetic activity in present-day plastid-lacking organisms, or ...

The LLA Retina combines Lukasiewicz logic arrays (LLAs) with photo-sensor clusters to work as a fuzzy edge detection mechanism and several other applications. In this presentation we have explored various approaches to excite and evaluate the device with several types of light sources including visible and infra-red laser beams. Based on the detailed studies on the device, one particular config...

Compositional changes in ginsenosides and crude saponin during enzymatic biotransformation of red ginseng were studied on three commercial polysaccharide-hydrolyzing enzymes, Pectinex, Termamyl, and Celluclast. Considerable enhancement of crude saponin production was observed with Pectinex, whereas hydrothermally processed black ginseng showed significant decrease. Celluclast-treated red ginsen...

the current status and distribution of the dragonflies (anisoptera) of pakistan were studied during 2005-2009. two dragonfly species were identified for the first time from pakistan. among these, rhodothemis rufa is a red, medium-sized dragonfly. lamelligomphus biforceps is also reported for the first time from pakistan and re-described owing to having minor taxonomic differences from that of f...

Red light-enhanced pelletability of phytochrome was observed in extracts of all 11 plants tested: Avena sativa L., Secale cereale L., Zea mays L., Cucurbita pepo L., Sinapis alba L., Pisum sativum L., Helianthus anuus L., Raphanus sativus L., Glycine max (L.) Merr., Phaseolus vulgaris L., and Lupinus albus L. This enhanced pelletability was observed in all 11 plants following in situ irradiatio...
