TL;DR: A catalog of γ-rays emitted following thermal-neutron capture in natural elements is presented in this paper, which is designed for use in high-resolution analytical prompt γray spectroscopy.

TL;DR: In this paper, the authors investigated heat transfer and pressure drop at supercritical conditions using carbon dioxide as a modelling fluid as a cheaper and faster alternative to using SCW and found that the majority of experimental data were obtained in vertical tubes, some data in horizontal tubes and just few in other flow geometry.

TL;DR: It is suggested that the maintenance of diversity in the absence of frequent modern-day recruitment, and resistance to further geographic differentiation in this spatially heterogeneous environment reflect occasional seedling establishment through "windows of opportunity" and more importantly, the species' clonal morphology.
Abstract: Trembling aspen (Populus tremuloides Michx.), a clonal angiosperm, is the most geographically widespread tree in North America. It is generally thought that most extant populations in the western interior of Canada and the United States became established shortly after glacial retreat, but sexual recruitment then effictively ceased owing to inimical climatic conditions. Six populations of trembling aspen were studied in the prairie and montane environments of Waterton Lakes National Park, Alberta. Vegetative tissues were analyzed for electrophoretically detectable variation in 13 enzymes encoded by 14 polymorphic loci and three monomorphic loci. All populations maintained high levels of interand intrapopulation diversity (P = 0.891; H = 0.319; A = 2.4). The mean fixation index, F, was -0.102, indicating some deviation from Hardy-Weinberg expectations. Genetic differentiation (FST = 3.0) was apparent in this ecologically diverse, but geographically small-scale, spatial setting. It is suggested that the maintenance of diversity in the absence of frequent modern-day recruitment, and resistance to further geographic differentiation in this spatially heterogeneous environment reflect occasional seedling establishment through "windows of opportunity" and more importantly, the species' clonal morphology. The phalanx growth form and concomitant physiological integration between ramets combine to spread the risk of death and buffer the effects of selection over time and space.

TL;DR: In this article, a tensile analysis of Hart is adapted to compressive loading, and indicates that the onset and termination of flow localization occurs earlier and later, respectively, than in rate sensitive materials.

TL;DR: Time-resolved fluorescence spectroscopy directly distinguishes between a decrease in fluorescence intensity due to quenching by an excess of unbound Eb from that due to a decreases in Eb binding to double-stranded DNA, suggesting that techniques which measure total steady state fluorescenceintensity of bound Eb in order to infer relative amounts of double- Stranded DNA must be interpreted with caution.
