By employing the p(+) nc-Si:H as a window layer, complete p-i-n structures were fabricated and characterized. Low leakage current and enhanced sensitivity in the UV/blue range were achieved by incorporating an a-SiC:H buffer between the p- and i-layers. (C) 2010 Elsevier B.V. All rights reserved.”
“Survey results show that in spring season, turbot population was concentrated in the Bulgarian SCH 900776 nmr – Romanian transboundary area and was shared between countries. The maxima of abundance indices occurred
in depths between 50 – 75 m in both areas. Length composition of turbot catches included size classes between 26.5 and 74.5 cm and low abundance of young individuals was observed. Age structure encompassed 2-8-year-old fish. Studies on the spawning process of turbot population show that an active
spawning process was www.selleckchem.com/products/gsk621.html observed in the Romanian area, but, in Bulgarian waters, the majority of individuals were resting after spawning.”
“Pseudoroegneria spicata (Pursh) A. Love and Elymus wawawaiensis J. Carlson & Barkworth are two native perennial grasses widely used for restoration in the Intermountain West. However, the rapid establishment and spread of Bromus tectorum L., an invasive annual grass, has led to a decline in the abundance of native perennial grasses. Proliferation of B. tectorum has been attributed to its early germination, superior cold-temperature growth, profuse root production, and high specific leaf area (SLA). To enhance restoration success, we compared B. tectorum to commercially available plant materials of two perennial rangeland bunchgrasses, P. spicata (cv. Whitmar, cv. Goldar, and Anatone Germplasm) and E. wawawaiensis (cv. Secar), for germination, seedling morphological traits, and growth rates https://www.selleckchem.com/products/gs-9973.html at the immature seedling
stage. We monitored germination and immature seedling growth in a growth chamber in two separate experiments, one under low (5/10 degrees C) and the other under high (15/20 degrees C) day/night temperatures. Compared to the average of the two perennials, B. tectorum was 93% (77%) greater at high (and low) temperature for root:shoot length ratio, but only 14% (14%) greater for root:shoot biomass ratio and 12% (19%) lower for SLA. This suggests that B. tectorum’s substantial investment in surface area of roots, rather than in shoot length, root biomass, or leaf area, may be responsible for the annual’s success at the early seedling stage. Compared to E. wawawaiensis, P. spicata averaged 65% (41%) higher shoot biomass, 39% (88%) higher root biomass, and 70% (10%) higher absolute growth rate, but 25% (15%) lower SLA and 15% (36%) lower specific root length (SRL) at high (and low) temperatures, respectively. Although P. spicata’s greater productivity may initially make for better seedling establishment than E.
