We have done geometry optimization of two conformers of Lantadene series C and D. The fundamental vibrational frequencies with intensity have been done by using B3LYP/6-311G (d, p) method. The complete vibrational assignments of wavenumbers are made on the basis of potential energy distribution (PED). The nonbonding interactions in Lantadenes C and D are calculated by using the same level theory at the bond critical point (BCP). The calculated topological parameters at BCP are utilized to determine the nature and strength of interactions. We have also computed HOMO–LUMO gap and plotted frontier orbital HOMO–LUMO surfaces, molecular electrostatic potential surfaces to explain the reactive nature of Lantadenes C and D. The electronic transition spectra UV–Vis spectra of Lantadenes C and D are calculated by using TDDFT theory. The values of hyperpolarizability show a probable use of these compounds in electro-optical applications. The natural bonding orbital theory is utilized to calculate transition of electron from donor to acceptor which is very useful to describe nonbonding as well as bonding interactions. The calculated value of Log P and Log S for Lantadene C Lantadene D established its pharmaceutical behaviors. The biological activity of Lantadenes C and D is also calculated by using PASS online server for Pa > 7 0 %. The docking of Lantadene C Lantadene D is also performed by using Auto dock with predicted drug by Swiss dock online server. [ABSTRACT FROM AUTHOR]

Background: Electrocautery for surgical incision is rarely used for fear of unhealthy healing and poor scar cosmesis. There is paucity of literature on the use of diathermy for incisions in elective surgeries in the randomised setting. The present study was designed to address this lacunae in literature. Material and Methods: This was a hospital-based prospective randomised control study conducted among 100 patients who underwent elective inguinal hernia surgery in a tertiary care center in Tamil Nadu, India from January 2019 to June 2020. The patients were randomised into two groups based on computer generated random numbers table. Post operative wound was evaluated on post operative day 2 and 5 using the Southamptom wound grade and scar cosmesis was assessed using the Manchester scar score at 6 months postoperatively. Results: On statistical analysis, for incision time, there was no significant difference between the two groups, whereas on evaluating the blood loss between the two groups there was statistically significant difference. There was no statistically significant difference between the two groups on day 2 and day 5 of the wound complication and 6 months postoperatively there was no significant difference between the two groups in terms of scar cosmesis. Conclusion: Diathermy incisions are comparable to a scalpel incision in terms of incision time but diathermy results in significantly less blood loss. Postoperative wound healing and scar characteristics were found to be similar for both groups with no statistically significant difference. [ABSTRACT FROM AUTHOR]

Tuberose (Polianthes tuberosa L.) is an important flower and grown in diverse climatic conditions for commercial purpose. Tuberose gained popularity in recent past due to its beauty, look, and many hues and aesthetic values. Despite of its beauty, tuberose flowers have a short shelf life, causing them to dry up early and decay within few days. Many research groups' attempts to improve the shelf life and flower quality of tuberose cut flowers by manipulating different chemicals and their concentration and combinations. Majority of these approaches include the use of non-harmful substances mainly salicylic acid, nanoparticles, and sucrose have been tried. These substances are known to extend the life and increase the quality of cut flowers. Many studies in the past showed that these substances separately or in combination have beneficial effect to extend the vase life and to improve floral longevity of tuberose cut flowers. Through this review, we have made an effort to discuss various strategies which may help to improve the vase life of tuberose cut flowers and their long-term maintenance in a distinctive and eco-friendly manner.

In deregulated environment, stability issues have become dominant. Reliability of the power is essential for successful operation of the power system. Often high and dynamic loading conditions present new challenges in terms of decision of the control strategies to the system operator at energy management centre. For the achievement of voltage stability, identification of weak buses is very important. Line stability indices are important predictors of the weak buses in the over loaded system. Identification of the weak buses is the first step of control strategy. This paper presents an effective methodology based on Artificial Neural Network (ANN) to predict the Fast Voltage Stability Index (FVSI). Comparative analysis of different topologies of ANN is carried out based on the capability of the prediction of FVSI. Results are validated through offline Newton Raphson (NR) simulation method. The proposed methodology is tested over IEEE-14 and IEEE-30 test bus System. [ABSTRACT FROM AUTHOR]
