The spin transition temperatures of [Fe(didentate)3]2+in acetonitrile (didentate = 2-X-benzimidazole) can be stepwise decreased by 40 K along the series X pyrazine > pyridine pyrimidine.

general, any n-sequence determines a multiset of (= n!/k!(n-k)!) k-sequences. "J Suppose, conversely, that we are given a multiset 01 k-sequences. Does that multiset come from some sequence? If so, is the source sequence unique? Such questions are reminiscent of the problem of reconstructing graphs from vertex-deleted sub raphs, which has received a great deal of attention in the last twent yea...

The paper deals with a new technique of fragile image watermarking. Proposed technique exploits inter-subband dependencies in order to minimize the influence of inserted watermark on the host image quality. Using the unique watermark based on the low-frequency subband, proposed scheme is resistant against attacks based on series of images analysis. Tampering detection ability of the proposed te...

In this work, separation performance of supported carbon membranes produced from Novolac Phenolic resin as the main precursor and carbon nanotubes as nanofiller were investigated for separation of CO2 from N2 and CH4. Supports were produced by carbonization of Novolac Phenolic resin-activated carbon mixture, and selective layer was coated by dip coating of prepa...

objective: the present study was designed to investigate the putative antidepressant effects of crocin and crocetin, two major active ingredients of crocus sativus l. (saffron) using mice in two different regimens of acute and sub-acute administration. material and methods: in acute treatment, antidepressant-like activities of crocin and crocetin (10, 20 and 40 mg/kg, i.p.) were evaluated using...

The combination process of UV/ S2O82-/Al2O3 leads to the production of radicals and radical hydroxyls, which could decompose and remove various pollutants, such as phenol. The present study aimed to investigate the photocatalytic efficiency of aluminum oxide nanoparticles and persulfate compilative processes in the removal of phenol. This e...

Methods A repeated measures design was employed where thirty female college-aged participants (Mage=20.1, sd =1.95) completed three counterbalanced testing sessions: a yoga session, an aerobic exercise session, and a baseline assessment. Participants were presented with the state sub-form of the Spielberger’s State Trait Anxiety Inventory and a list of 40 words immediately after the exercise se...

<p class="abstrak">Long-term use of NaNO<sub>2</sub> in food preservatives causes a variety health problems, particularly for kidney function. Natural antioxidants that can reduce the effects free radicals are required to prevent these effects. The sweet flag plant is medicinal with high antioxidant potential. This study aims determine effect rhizome extract (SFRE) on morpholo...

In situ tracking of chemical phase transformation, mapping, and composition information of a battery with CuO as the anode was performed with quantitative analysis at sub-30 nm resolution with a 40 × 40 μm field of view using transmission X-ray microscopy combined with spectroscopy. A size-dependent and core-shell lithiation-delithiation mechanism was suggested for the electrochemical reaction.
