The isotropic-nematic (I-N) phase transition of side-chain polymer liquid crystals is intrinsically a weak first-order transition with a biphasic region spread over a wide temperature interval. In the presence of high magnetic fields we find the I-N transition to become a strong first order. The I-N biphasic region shrinks its temperature window as larger magnetic fields are applied, until it c...

Vapor-phase naphthalene hydrogenation over various supported Pt catalysts was studied in a continuous fixed-bed microreactor. Experimental results indicated that the catalytic activity of the catalyst strongly depended on the nature of the support and the pre-reduction temperature. Reaction order was independent of the support as the reaction was pseudo-first-order with respect to naphthalene i...

objectives: the purpose of the study was to compare the emotion regulation strategies of blind and sighted students.  methods: the research method used was descriptive and causal-comparative, and the statistical population included all the sighted and blind students at the university of isfahan and the islamic azad university of khorasgan. the sample volume was 64 members (32 members in each gr...

supply chain network   receding horizon control demand move suppression term   supply chain networks are interconnection and dynamics of a demand network. example subsystems, referred to as stages, include raw materials, distributors of the raw materials, manufacturers, distributors of the manufactured products, retailers, and customers. the main objectives of the control strategy for the suppl...

The method and probability of distinguishing between the Λ cold dark matter (ΛCDM) model and modified gravity are studied from future observations for the growth rate of cosmic structure (Euclid redshift survey). We compare the mock observational data to the theoretical cosmic growth rate by modified gravity models, including the extended Dvali–Gabadadze–Porrati (DGP) model, kinetic gravity bra...

It has been proposed that DNA methylation plays an important role in the inactivation of transposons. This view stems from a comparison of the degree of methylation of transposons in the active and inactive state. However, direct evidence for the degree of methylation required for the suppression of transposition has not been reported. Transposon Tam3 in Antirrhinum majus undergoes somatic reve...

Pristine and substituted spinels, Li(M1/6Mn11/6)O4 (M ~ Co1/6, Co1/12Al1/12) were prepared and their cathodic performance up to 80 cycles at ambient temperature and at 50 uC and the Li ion kinetic parameters obtained by galvanostatic intermittent titration technique (GITT) at ambient temperature and 50 uC and electrochemical impedance spectroscopy (EIS) at ambient temperature up to 80 cycles we...

The Saccharomyces cerevisiae cdc33ts4-2 mutant produces a temperature-sensitive allele of the cap-binding subunit of eukaryotic initiation factor-4F (also termed eIF-4E). From a Drosophila cDNA library constructed in a multicopy yeast shuttle vector, a clone was isolated which restored the ability to grow at elevated temperature to cdc33ts4-2 cells. The rescuing Drosophila clone encodes a small...

Here we report the effect of passivating diluent chain length and sensor interrogation temperature on the electrochemical DNA (E-DNA) sensor's mismatch discrimination capability. Both stem-loop and linear probe-based E-DNA sensors were constructed with various diluents, including 6-mercapto-1-hexanol and longer chain hydroxyl-terminated alkanethiols. Contrary to previously reported results, we ...

The heavy air pollution, known as Atmospheric Brown Cloud (ABC), has been research mainly for its radiative effects and cloud condensation nuclei (CCN) activity that act to nucleate larger number of smaller cloud drops, and hence suppress coalescence and warm rain forming processes (Ramanathan et al., 2001). Precipitation in convective clouds with aerosol-induced suppressed coalescence is initi...
