Biological Evaluation of a Novel Potentially Tridentate Schiff Base and its Selected Transition Metal(II) Complexes

A Schiff base ligand was synthesized by the condensation of antipyrine-4-carboxaldehyde with 2-amino-3-carboxyethyl-4,5,6,7-tetrahydrobenzo[b]thiophene and its Co(II), Ni(II), Cu(II) and Zn(II) complexes were prepared by microwave assisted solvent free synthesis. The biological activity of the prepared ligand and the metal complexes was assessed by in-vitro testing of their effect on the growth of various strains of bacteria and fungi. A gel electrophoresis assay demonstrated the ability of the complexes to cleave the pUC19 DNA. The alpha amylase inhibitory activity of the ligand and the metal complexes were evaluated and found that metal complexes possess higher activity than the ligand

Resistive Coupled Microwave Sintering of Nanostructured ZnO for Solar Window Applications

ZnO found applications in solar windows and UV shielding windows. In the present work nanostructured ZnO  is synthesized by the single step auto-igniting combustion technique. Various powder characterization techniques revealed that ZnO powders is phase pure and crystallised in face centred cubic lattice with an average crystallite size of 26  nm. A novel sintering strategy called resistive coupled microwave sintering is developed and optimised during the course of work by effectively coupling resistive heating and microwave heating in definite proportions. By this method ZnO is sintered to 98.3% of the theoretical density at  1050oC for a soaking duration of 30 minutes. The pellet sintered using resistive coupled microwave heating shows high load independent hardness of 2.37 GPa .  &nbsp

Repercussions Ensuing COVID 19 Pandemic in Portfolio Management of Individual Investors

Novel coronavirus created repercussions in the economy, which affected the investors, public, and policymakers. It affected the financial market drastically. Individuals in different parts of the world struggled, and its effect on the stock market is inevitable. Investors should first determine their risk tolerance level and invest to generate maximum profit. This paper aims to understand the influence of COVID 19 on individual investors\u27 investment and financial decisions. Data were collected from 60 individual respondents using purposive sampling. Individuals with salaried and business occupational status were included in the study. It is identified that the government\u27s lockdown restrictions severely impacted individuals\u27 income and directly affected savings and investment behaviour. Investors were identified to prefer savings options compared to investment instruments, and they are identified to prefer Bank deposit, insurance, post office savings scheme and gold. Individuals prefer mutual funds more due to their liquidity, professional expertise, and reliability among investment instruments. It is concluded that the COVID 19 pandemic changed the risk preference of individual investors as their preference shifted from risky assets to risk-free assets. In contrast, some individuals observed it as a golden opportunity to invest

PERFORMANCE EVALUATION OF THE INDIAN BANKING SECTOR: PRE AND POST REFORMS PERIOD ANALYSIS

Reform is not a static term but indicates a journey of the banking sector. It not only changed the functioning of the banking sector but also improved the efficiency productivity and effectiveness of the banking fraternity in India. In this connection government is also playing a vital role through implementing the various recommendations put forward by various committees contributing towards reforms. Here an attempt had been made to critically analyze the impact of banking reforms (Narasimham Committee II) which took place in 1998 in the Indian banking sector. To assess the impact on the banking sector, the reform period was classified as pre and post periods.  The year 1998 was considered as the year of banking reforms.  Hence pre- reforms period consist of 15 years from 1983 to 1997 and post reforms period was selected from the year 2001 to 2015 after giving a time gap of two years (1999 and 2000) as by 2001 the reforms measures had exerted their full impact on the performance of the Indian banking sector.Hence this paper is an attempt to explore the performance of the Indian banks for a period of 15 years in the light of banking reforms with the help of slope analysis
