The Arabidopsis HOBBIT (HBT) gene encodes a homolog of the CDC27 anaphase-promoting complex/cyclosome subunit and is essential for postembryonic development. We induced loss-of-function clones by Cre/lox-mediated recombination of a single complementing HBT transgene in a background homozygous for the strong mutant allele hbt(2311). Defects in cell division and cell expansion are the primary con...
در سلول خورشیدی حساس شده با رنگدانه، مولکول رنگدانه نقش جذب نور را بر عهده دارد که نقشی کلیدی در عملکرد این سلول خورشیدی است. یکی از ویژگی هایی که بر طیف اپتیکی رنگدانه ها اثر می گذارد، اندازه ی نانو مولکول ها است. در این مقاله طیف اپتیکی نانو مولکول های خانواده ی کومارین با اندازه های مختلف با استفاده از دو روش تابعی چگالی تنگابست وابسته به زمان و نظریه ی تابعی چگالی وابسته به زمان محاسبه می ش...

Based on the solidification heat transfer model and CAFE model, behavior structure of 2311 die steel, with a cross-section dimension 415 × 2270 mm at different casting speeds, specific water flow superheat, is numerically simulated. Nail-shooting acid-etching experiments are carried out slab to verify model’s macroscopic size. With increase in speed, slab’s central equiaxed grain ratio (ECR) de...
This paper presents students’ word associations with terms regarding the Wadden Sea. A continuous free word-association method was used in which students from secondary schools (n = 3119, average age: 13.54 years) reported their stimulus words Sea, mudflat hiking tour, and tides written form. Data were collected living close to Sea inland. We performed a quantitative content analysis including ...
d-erythro -Sphingosine-1-phosphate (2), an intermediate in sphingosine metabolism, shows a diversity of biological activities. Comparable roles might be anticipated for d-ribo -phytosphingosine-1-phosphate (1). We describe an efficient three-step chemical synthesis of 1 from d-ribo -phytosphingosine. Our approach is based on standard phosphoramidite methodology and on the finding of Boumendjel ...
Centre of Research & Technology Hellas, Information Technologies Institute (+30) 2311 257738 {athstavr, gmeditsk, andreadisst, thtsompa, ikom}@iti.gr ABSTRACT Dem@Lab is an ambient intelligence framework, which supports monitoring behavioral aspects of individuals in goaloriented scenarios, within controlled, pervasive environments. Semantic Web technologies, such as OWL 2, are extensively empl...
For wide range of parameters, we study traveling waves in a diffusive version of the Holling-Tanner predator-prey model from population dynamics. Fronts are constructed using geometric singular perturbation theory and the theory of rotated vector fields. We focus on the appearance of the fronts in various singular limits. In addition, periodic traveling waves of relaxation oscillation type are ...
