In the fields of engineering, industry, and biology, thin needles serve a critical role. The thermocouple hot wire anemometer for wind speed monitoring, microscale heat extraction cooling systems, and electronic microstructure outfitting are only a few of the needle"s key applications. In view of these applications the present investigation is carried out to study the Casson hybrid nanofluid flow for the entropy creation and the pre-exponential factor law in Darcy Forchheimer medium on the thin needle. The set of governing equations describing the flow problem will be converted to a system of ordinary differential equations with suitable similarity variables. The numerical solutions are obtained by the aid of mathematical computing software by applying the Runge Kutta Fehlberg 45 method with shooting scheme. The numerical results for various parameters are produced, and an entropy analysis is performed. Axial velocity falls as the porosity and Darcy parameters are increased. The thermal performance improves as the needle size and Brinkman number increase. The concentration profile is improved by thermophoresis, Brinkman number, and activation energy parameter. The entropy generation and surface drag force will increase as the porosity parameters are increased, while the Bejan number will decrease.

<P>Using the latest physical modeling and constrained by the most recent data, we develop a phenomenological parameterized model of the contributions to intensity and polarization maps at millimeter wavelengths from external galaxies and Sunyaev-Zeldovich effects. We find such modeling to be necessary for estimation of cosmological parameters from Planck data. For example, ignoring the clustering of the infrared background would result in a bias in ns of 7s in the context of an eight-parameter cosmological model. We show that the simultaneous marginalization over a full foreground model can eliminate such biases, while increasing the statistical uncertainty in cosmological parameters by less than 20%. The small increases in uncertainty can be significantly reduced with the inclusion of higher-resolution ground-based data. The multi-frequency analysis we employ involves modeling 46 total power spectra and marginalization over 17 foreground parameters. We show that we can also reduce the data to a best estimate of the cosmic microwave background power spectra, with just two principal components (with constrained amplitudes) describing residual foreground contamination.</P>
<i>Euphausia pacifica</i> brood sizes: a North Pacific synthesis
Feinberg, L. R.,Shaw, C. T.,Peterson, W. T.,Dé,cima, M.,Okazaki, Y.,Ju, S.-J. Oxford University Press 2013 Journal of plankton research Vol.35 No.6
<P><I>Euphausia pacifica</I> occupy a remarkably wide range of ecosystems. We examined the differences in brood sizes from eight regions of the North Pacific to explore how variation in the brood size might contribute to their success over such a range. We show a compilation and analysis of short-term <I>E. pacifica</I> brood size incubations from around the North Pacific rim, ranging from the Yellow Sea (YS) (Korea) to southern California (SC), USA. Brood sizes for <I>E. pacifica</I> are highly variable in all regions and range from 5 to 697 eggs overall. Median brood sizes were largest in the YS and off Newport, Oregon and the maximum brood sizes were greatest in the regions off the coasts of Oregon and Washington, USA followed by the YS. Quantile regression analysis revealed that there was a significant relationship between the female length and the maximum brood size (95% quantile) for broods from SC, Oregon, and Washington, USA as well as Toyama Bay, Japan, indicating that the maximum brood size is limited by the female length in these regions. This suggests that other factors, hydrographic conditions, food quantity/quality or physiological condition of females, may limit maximum brood sizes in the other regions examined here.</P>

<P>Here, we identify the Arabidopsis thaliana ortholog of the mammalian DEAD box helicase, eIF4A-III, the putative anchor protein of exon junction complex (EJC) on mRNA. Arabidopsis eIF4A-III interacts with an ortholog of the core EJC component, ALY/Ref, and colocalizes with other EJC components, such as Mago, Y14, and RNPS1, suggesting a similar function in EJC assembly to animal eIF4A-III. A green fluorescent protein (GFP)-eIF4A-III fusion protein showed localization to several subnuclear domains: to the nucleoplasm during normal growth and to the nucleolus and splicing speckles in response to hypoxia. Treatment with the respiratory inhibitor sodium azide produced an identical response to the hypoxia stress. Treatment with the proteasome inhibitor MG132 led to accumulation of GFP-eIF4A-III mainly in the nucleolus, suggesting that transition of eIF4A-III between subnuclear domains and/or accumulation in nuclear speckles is controlled by proteolysis-labile factors. As revealed by fluorescence recovery after photobleaching analysis, the nucleoplasmic fraction was highly mobile, while the speckles were the least mobile fractions, and the nucleolar fraction had an intermediate mobility. Sequestration of eIF4A-III into nuclear pools with different mobility is likely to reflect the transcriptional and mRNA processing state of the cell.</P>
