Esterification reactions carried out using various mineral acids are threat to environment hence process modification using commercially viable heterogeneous catalysts are in demand. In current work, the esterification of tri-ethanolamine (TEA, C6H15O3N) with several fatty acids in liquid phase has been investigated on a series of heterogeneous mixed metal oxides catalyst prepared by co-precipitation method, crystallizing with spinel lattice such as, CuFe2O4, ZnFe2O4, CoFe2O4, NiFe2O4 and 10% (w/w)ZnFe2O4 supported on SiO2 and ZrO2. The best catalyst for the selective preparation of 2-(bis(2-hydroxyethyl)amino)ethyl alkanoate was 10% (w/w) ZnFe2O4 supported on ZrO2. Detail comparison of a 10% (w/w) ZnFe2O4/ZrO2 prepared by co-precipitation method was carried out with 10% (w/w) ZnFe2O4/ZrO2 prepared by template route for the selective formation of 2-(bis(2-hydroxyethyl)amino)ethyl alkanoate. The effects of variety of parameters including effect of catalyst preparation were studied in a batch reactor.

The purpose of this paper is to establish the existence of solution to Bessel-type boundary value problem. In the sequel some fixed point theorems are proved. It is worth mentioning that our results cannot be concluded from the existing results in the milieu of associated metric spaces. Utilizing an innovative pictorial technique, an example is worked out substantiating the utility of hypothesis of our results. In an another paper, authors recently established some inventive applications of G-metric spaces in science and engineering.

This paper aimed to elucidate the effect of Erythrina variegata L. bark on scopolamine-induced memory impairment in rats and to decipher the molecular mechanism of phytoconstituents via the utilization of gene set enrichment analysis, network pharmacology coupled with in silico docking study. First, three models i.e. Morris Water Maze (MWM), Elevated Plus Maze (EPM), and Passive Avoidance Paradigm (PA) were utilized to elucidate the memory function. Second, the level of biomarkers i.e. acetylcholinesterase enzyme, reduced glutathione, and lipid peroxidation level were measured in brain tis- sues. Third, the key bioactive phytoconstituents targeting potential protein targets and pathways were identified through gene set enrichment analysis and network pharmacology. Lastly, the interaction between bioactive phytoconstituents with their respective targets was confirmed by molecular docking analysis. The MWM, EPM, and PA activity showed, scopolamine administration increased Escape Latency Time (ELT), Transfer Latency (TL), and Step Through Latency (STL) respectively on day 0th, 7th, 14th, and 21st, whereas treatment with E. variegata extract significantly reverse the ELT, TL and STL activ- ity. The decreased level of Acetylcholinesterase (AChE) and MDA level in treated animals reflected the enhanced memory and was found to be comparable withclinically proven drug i.e. donepezil. Sixty compounds were identified in EV bark, among which twenty-two compounds are predicted to modulate potential targets involved in AD and considered potentially bioactive. Further, the docking study revealed, Alpinumisoflavone, Auriculatin, Osajin, and Scandenone to have the highest binding affinity with Tau protein, Whereas Donepezil and Glucoerysodine with acetylcholinesterase enzyme.

An analytical model to predict the temperature distribution and ablation depth in excimer laser ablation process by solving onedimensional heat conduction equation has been proposed. The model takes into account aspects like temperature dependent thermal properties for polycarbonate material and re-solidification during pulse off-time. The effects of fluence and number of pulses with and without consideration to the temperature dependent thermal conductivity and pulse delay have been investigated. It is observed that consideration to temperature dependent thermal conductivity and re-solidification during pulse ‘off-time’ results in an appreciable improvement in the accuracy of ablation depth prediction and the error being within ± 0.8 μm.

In this article, we utilize the concepts of hybrid rational Geraghty type generalized F-contraction and to prove some fixed point results for such mappings are in the perspective of partially ordered b-metric like space. Some innovative examples are also presented which substantiate the validity of obtained results. The example is also authenticated with the help of graphical representations.

In this article, we define the notion of a non-negative function satisfying property of oneness. Utilizing this concept, certain unified fixed point results are established. Furthermore generalized φ-contractions mapping and some fixed point results in the framework of symmetric space are also presented. Some well-known results from the existence literature are obtained through our introduced setting. Results are substantiated by some innovative examples with the aid of visualization of surfaces. Moreover applications of obtained theory for the existence for the system of integral equations as well as for the system of functional equations occurred in dynamic programming are also presented.
