ABSTRACTSeeding from bulk silicon (lateral epitaxy) has been used in Ar+ laser recrystallization to achieve subboundary free silicon on insulator areas. On these areas C.MOS devices have been performed using almost entirely the standard processing steps of a bulk micronic C-MOS technology. n -MOS transistors with channel length as small as 0.3 um have shown very small leakage currents. This is attributed especially to the lack of subboundaries. A 40 % increase in the dynamic performances in comparison with equivalent size C-MOS bulk devices has been obtained (93 ps of delay time per stage for a 101 stages ring oscillator with 0.8 μm of channel length). This is the best result presented so far on recrystallized SOI. No special requirements are needed in the lay out of the circuit with the chosen seed structure. Furthermore an industrial processing rate for the laser recrystallization processing has been achieved using an elliptical laser beam, a high scan velocity (30 cm/s) and a 100 μm line to line scan step (a 4' wafer in 4 minutes).

Carex setosa Boott is a highly variable Sino-Himalayan species. In the protologue, the species was described by Francis Boott with three distinct morphotypes. Morphotypes were further illustrated in three different tabs. J.D. Hooker collected all the morphotypes in Lachen, Sikkim in 1849. The Indian morphotypes are Carex setosa var. setosa. The name Carex setosa is lectotypified here.

Fibril Morphology

AbstractSeveral studies showed that seeding of solutions of monomeric fibril proteins with ex vivo amyloid fibrils accelerated the kinetics of fibril formation in vitro but did not necessarily replicate the seed structure. In this research we use cryo-electron microscopy and other methods to analyze the ability of serum amyloid A (SAA)1.1-derived amyloid fibrils, purified from systemic AA amyloidosis tissue, to seed solutions of recombinant SAA1.1 protein. We show that 98% of the seeded fibrils remodel the full fibril structure of the main ex vivo fibril morphology, which we used for seeding, while they are notably different from unseeded in vitro fibrils. The seeded fibrils show a similar proteinase K resistance as ex vivo fibrils and are substantially more stable to proteolytic digestion than unseeded in vitro fibrils. Our data support the view that the fibril morphology contributes to determining proteolytic stability and that pathogenic amyloid fibrils arise from proteolytic selection.

Abutilon is an important medicinal plant. Its various plant parts such as leaves, flowers, fruits and seeds were used to treat various diseases and ailments from the ancient time. Present work deals with the investigation of three species of Abutilonviz. Abutilon indicum, Abutilon pannosumand Abutilon ramosum with a view to study macro morphological variations and to identify a set of diagnostic characters for individual Abutilon species. Distinct variations exist in stem surface and colour, leaf shape and size, flower diameter, fruit colour, shape and size, number of mericarps per fruit and seed structure. All these macromorphological variations were helpful in identification and delineation of the plant species.

Abstract Bombus simillimus SMITH is a west Himalayan species, known only from Pakistan and India. In the Indian Himalaya this species is restricted to Kashmir, Himachal Pradesh and Uttarakhand. So far, it has never been recorded from other regions. Its females (workers) can be recognized by the chocolate brown pubescence of the metasomal terga 1 and 2. The colour pattern of the queen is very distinct, with the whole body coloured black except for the last two metasomal terga, which are brick-red. In Kashmir Himalaya it is widespread around the lower mountain coniferous forest and was found foraging heavily on Trifolium pratense, Lavatera cashmeriana, Carduus spp. and Cirsium spp. Being very common and having a very wide distributional range, it is associated with a sizeable number of host plants. Due emphasis has been laid on its detailed taxonomic descriptions, synonymy, host plants, distribution pattern and illustration. Thirty-five food plants of this species have been recorded from the study areas.
