Opis:
Elven (E)-1-(4-bromophenyl)-3-(substituted phenyl)-2-propen-1-ones are formed using sodium hydroxide catalyzed Aldol condensation between 4-bromoacetophenone and substituted benzaldehyde. The production of these chalcone compounds are above 90%. These α, β unsaturated ketones were specified by their physical constants and spectral data (UV, IR, 1H and 13C-NMR). Hammett substituted constants (σ, σ+, σI & σR and F and R parameters have been used for correlating the spectral values of these α, β unsaturated ketones by using single and multi-linear regression analysis. The impacts of substituents on the spectral data have been known on statistical analysis. By using Bauer-Kirby method the anti-microbial activities of these (E)-1-(4-bromophenyl)-3-(substituted phenyl)-2-propen-1-ones compounds are estimated.

Opis:
About nine substituted (E)-1-(4-methoxyphenyl)-3-phenylprop-2-en-1-ones have been synthesized by solvent-free method. These enones were analyzed by spectral techniques. The characteristic spectral frequencies were correlated through Hammett equation with Hammett substituent constants, F and R parameters using single and multi-regression analysis method. From the statistical analysis results, the quantitative structure activity relationships have been discussed by means of effects of substituents on the spectral frequencies.

Opis:
The research, presented in this paper, concernes the controllability of a multi-agent network with a directed, unweighted, cooperative, and time-invariant communication topology. The network’s agents follow linear and heterogeneous dynamics, encompassing first-order, second-order, and third-order differential equations over continuous time. Two classes of neighbour-based linear distributed control protocols are considered: the first one utilises average feedback from relative velocities/relative accelerations, and the second one utilises feedback from absolute velocities/absolute accelerations. Under both protocols, the network’s agents achieve consensus in their states asymptotically. We observe that both of the considered dynamical rules exploit the random-walk normalised Laplacian matrix of the network’s graph. By categorising the agents of the network into leaders and followers, with leaders serving as exogenous control inputs, we analyse the controllability of followers within their state space through the influence of leaders. Specifically, matrix-rank conditions are established to evaluate the leader– follower controllability of the network under both control protocols. These matrix-rank conditions are further refined in terms of the system matrices’ eigenvalues and eigenvectors. The inference diagrams presented in this work provide deeper insights into how leader– follower interactions impact the network controllability. The efficacy of the theoretical findings is validated through numerical examples.

Opis:
Pharmacognosy of the flowers of Saraca asoca (Roxb.) De Wilde has been carried out to lay down standards for the genuine drug Ashoka with the detailed anatomy of various floral appendages. The aim of the present study is to determine the physico-chemical profile, preliminary phytochemical screening, fluorescence analysis and chemical composition by HPTLC of the medicinally important plant Saraca asoca. These observations would be of immense value in the botanical identification and standardization of the drug in crude form. This study would help distinguish the drug from its other species.
