Deprotonation of the two terminal COOH groups on a 4,4'-bipyridinium linear derivative leads to a pronounced slow down on the kinetics of threading and unthreading by the cucurbit[7]uril host.

buprenorphine is a partial mu agonist and kappa antagonist which is used for the treatment of pain and opioid addiction. a mixture of buprenorphine hydrochloride and naloxone hydrochloride has been approved for the treatment of opioid dependence.in this study a third order derivative spectrophotometric method based on zero-crossing technique has been used for the simultaneous determination of b...

The adenovirus 7-simian virus 40 hybrid virus population E46(+) was subjected to fixed-angle equilibrium density gradient centrifugation in CsCl. A difference in buoyant density between the hybrid virion and its nonhybrid adenovirus 7 counterpart was noted, the hybrid virion possessing the lower buoyant density. This difference in buoyant density appeared to be accentuated in a population of ad...

Starting from second-order conditions for C scalar unconstrained optimization problems described in terms of the second-order Dini directional derivative, we pose the problem, whether similar conditions for C vector optimization problems can be derived. We define second-order Dini directional derivatives for vector functions and apply them to formulate such conditions as a Conjecture. The proof...

The synthesis of a series of 7-[(Z)-2-(2-aminothiazol-4-yl)-2-oxyiminoacetamido] -3-ammoniomethyl-3-cephems is described. Variations of an oxyimino moiety in the 7-side chain and a quaternary ammonium moiety in the 3-side chain were examined and structure-activity relationships studied. BMY-28142, the 3-(N-methylpyrrolidinio)methyl derivative of the 7-alpha-methoxyimino series of cephalosporins...

We construct the most general theory of 2D Einstein-dilaton gravity coupled with $U(1)$ gauge fields that contains all 2-derivative and 4-derivative interactions allowed by diffeomorphism invariance. renormalise action obtain vacuum solution as well black hole solution. The in UV is dominated Lifshitz$_2$ dynamical exponent ($z=\frac{7}{3}$) while on other hand, spacetime curvature diverges we ...

In the crystal structure of the title compound, C(7)H(10)N(2)O(2)S, a benzoic acid derivative, inter-molecular N-H⋯O inter-actions link the mol-ecules into a three-dimensional network.

A universal approach by Laplace transform to the variational iteration method for fractional derivatives with the nonsingular kernel is presented; in particular, the Caputo-Fabrizio fractional derivative and the Atangana-Baleanu fractional derivative with the non-singular kernel is considered. The analysis elaborated for both non-singular kernel derivatives is shown the necessity of considering...

Objective: Viola odorata has been used since ancient times. According to Traditional Iranian Medicine (TIM) sources, it a cool and moist temperament is for treatment of different diseases. Due the low side effects numerous beneficial this plant, study aims review its therapeutic from perspective TIM modern medicine. Methods: In study, search was conducted materials in many books such as Canon M...

The modification of the Clarke generalized subdiNerentia1 due to Michel and Penot is a useful tool in determining differentiability properties for certain classes of real functions on a normed linear space. The Glteaux differentiability of any real function can be deduced from the GBteaux differentiability of the norm if the function has a directional derivative which attains a constant related...
