The kinetics of phosphine substitution in CpRu(PAr3)2Cl by PMePh2 under pseudo-first order conditions in CDCl3 have been measured for PAr3 = PPh3, 1a, PPh2(p-tol), 1b, P(p-tol)3, 1c, P(p-CH3OC6H4)3, 1d, and P(p-FC6H4)3), 1e. Activation parameters characteristic of a dissociative pathway (ΔH(†) = 110-124 ± 2 kJ mol(-1), ΔS(†) = 16-44 ± 5-12 J mol(-1) K(-1)) are observed for all five compounds. T...

In each case, the anaphorically related elements are italicized. In (1a), \a presentation" is the antecedent for the pronoun \it", and in (1b), \gave a presentation" is the antecedent for the VPE. Similarly, in (1c), we view the \past" in the rst clause as the antecedent for the \past" in the second clause. This links the time of leaving to the time of giving the presentation. In (1d), we regar...

The germplasm collection of 87 wheat-wheatgrass hybrids developed in Tsitisin Main Botanical Garden (Russia, Moscow) was evaluated for resistance to pre-harvest sprouting (PHS) by spike sprouting (SS) and germination index (GI) assays as well as for spike and grain features. The PHS resistance variation and haplotype polymorphism of the wheatgrass ThVp-1 and wheat TaVp-1B genes orthologues of V...

Road, railway and track networks are important features of satellite imagery. Automated detection of tracks in mountainous terrain using satellite imagery is a difficult task. The track and the shadow signature of the mountainous terrain are almost same. The presence of ridges and snow also creates a lot of ambiguity. Moreover due to poor sunlight condition in the mountainous terrain the images...

In embryos of the gastropod Ilyanassa obsoleta, the first-quartet micromeres of the A, B and C lineages (1a, 1b, and 1c) are each competent to form an eye in response to signaling from the 3D cell. The first-quartet micromere of the dorsal D lineage (1d) is smaller than the others, divides at a slower rate, and lacks the ability to form an eye. These properties of 1d all depend on inheritance o...

Control of microstructure parameters that affecting the Al-Ti-C master alloys grain refining efficiency is leading to improve the aluminum grain refinement. This study was an attempt to produce Al-Ti-C master alloys that provide these controlling factors with relying on the solute effect theory. The produced master alloys were examined by using scanning electron microscopy (SEM), energy-dispers...

The L-type Ca channels mediate depolarization-induced influx of Ca into a wide variety of cells and thus play a central role in triggering cardiac and smooth muscle contraction. Because of this role, clinically important classes of 1,4-dihydropyridine, phenylalkylamine, and benzothiazepine Ca channel blockers were developed as powerful medicines to treat hypertension and angina pectoris. Molecu...

Abstract Background and Aims Tolvaptan is the first disease-modifier therapy proven to slow eGFR decline in high-risk patients with ADPKD. However, barriers its use real-life settings have not been examined. Method Single-center, retrospective study of 523 current or new ADPKD followed at Center for Innovative Management PKD Toronto, Ontario between January 1, 2016 December 30, 2018. All had cl...

789 with a reduced left ventricular ejection fraction (40%), moderate mitral valve insufficiency, and moderate ‐to ‐severe tricuspid valve insufficiency. In the parasternal long ‐axis view (FIGURE 1C and 1D) and the apical 5 ‐chamber view (FIGURE 1E–1G), an accessory structure was found in the region of the left ventricular outflow tract. Localization A 40 ‐year ‐old patient with no known medic...

We describe a method for tying a self-locking knot to apply tension to a free tendon end for hamstring graft anterior cruciate ligament reconstruction. This is faster, safer and easier than Whip stitching and is secure enough to feed the graft through bone tunnels. The suture is folded and the tendon is laid on top (Fig 1a). The suture ends are then fed over the tendon and through the loop (Fig...
