. The unique superhydrophobic property of lotus leaf, encouraged researchers to fabricate artificial superhydrophobic surfaces (SHs) adopting different methods. The purpose of this work is to attempt a modest, robust and environmentally safeprocedure to build a superhydrophobic surface on aluminium substrate by wet-chemical grafting. The substrate after few pretreatments like mechanical, chemical etching, anodizing at different current density and at different time duration was immersed in a solution containing sodium hydroxide in deionized water, lauric acid in ethanol. The effect of duration of anodization and sealing on the production of superhydrophobic surface was highlighed. Using Scanning Electron Micrsocopy (SEM) the surface morphology of the bare aluminium substrate and superhydrophobic surface. Using static water contact angle (WCA) measurements the non-wetting property of the as such fabricated superhydrophboic surface was studied and compared with the bare aluminium substrate. The corrosion resistance of the fabricated superhydrophobic surface in 3.5 % NaCl medium was examined by potentiodynamic polarization method and compared with the bare aluminium substrate. The fabricated SHs showsvery good corrosion resistance in comparison with the bare aluminiuim substrate in 3.5 % NaCl medium..

. A finite element analysis of an annular raft and a circular raft is undertaken in this work. Different ratios of inner radius to outer radius are chosen to examine the effect of geometrical characteristics of annular rafts. The ratio of radius of ring beam to outer radius of raft was also varied. Finite element method is adopted to determine critical moments and deflections in both annular and circular rafts. Comparison of these critical moments and deflections is made for both annular raft and circular raft,for selection of suitable type of raft foundation. Finite element analysis of both the rafts is carried out using ANSYS software.The results show that values of critical moments and deflections in annular raft are less in comparison with those values in circular raft. Different ratios of inner radius to outer radius and radius of ring beam to radius of raft effect critical moments and deflections.

. Cricket is more than simply a sport in India; it is a religion with a sizable following. Cricket has a global fan base of more than a billion people, with the Indian subcontinent accounting for nearly all of them. It is quite normal that children and adults can be seen playing street cricket on India's streets and narrow footpaths. To meet out the expectations of citizens of cricket crazy nation, the Board of Control for Cricket in India (BCCI) determined to expand the game to reap benefit through the introduction of intra country cricket league in 2007, following the T20 World Cup victory. In 2008, the Indian Premier League (IPL) was born as a result of this. It quickly became BCCI's most lucrative annual sporting event just a few years after its inception. The presentation will provide an overview of the operations, revenue, and contribution of IPL to the Indian economy.

. Insider trading is a pervasive stock market malpractice that has existed since the inception of the security market. Insider trading is notoriously difficult for regulators worldwide to crack down on. India has a dismal track record when it comes to prosecuting insider traders. In the last three decades of Sebi’s existence, there hasn’t been a single conviction for insider trading. In this study, we mainly inspectthe features of insider trading by examiningkey indicators during the time length before the release of insider information. In our investigation, we proposed a methodology for detection of insider trading in Indian stock market. To start with, the insider trading cases that happened in the Indian financial exchange we collected corporate filing data from NSE website for each company of NIFTY 50, which has different columns related to price, action and person or organization doing that action from 1stJanuary to a day prior to the publicationof financial results of December quarter offiscal year 2020-21. On doing as such, we have seen that enormous exchange have been done prior to publicationof financial results in some companies, which can be suspected as insider trading. At that point, themachine learning algorithms were utilized for preparing and for foreseeing Insider trading. Then, the algorithms were used for training and for predicting insider trading. Finally, their performance wasmeasured, compared and accuracy was calculated.Experiments revealed that the recommended method successfully achieved the best accuracy. This could be amazingly helpful for detecting insider trading in future, not only in Indian stock market, but also in other stock exchanges. The proposed approach and results in this examination is of incredible importance for market controllers to improve their oversight proficiency and precision on insider trading.. machine learning, deep learning..

: Stabilization of delayed inertial neural networks based on impulsesl is investigated in this paper. Delay-dependent sufficient conditions of stabilization results are obtained as linear matrix inequalities via Lyapunov stability theory which involves the construction of Lyapunov-Krasovskii functional. Information of time-delay is taken into account to obtain these results. Here, time-delay is considered to be time-varying and the activation function is assumed to be sector bounded. Derived conditions can be validated via MATLAB. Finally, an example is provided to support the derived results.

As a result of continuous technological breakthroughs and manufacturing process improvements, the global industrial environment has altered drastically in recent years. Industry 4.0 is a relatively new concept, and academic study is just now beginning to focus on this still-controversial and ill-defined topic. This study includes a review of the literature in order to better understand and appreciate this issue in its technical context. Cyber-Physical Systems, strengthened by the Internet of Things, link the digital and physical worlds in this new industrial paradigm. This concept is predicted to have a big impact on industry, markets, and the economy, improving production processes and increasing efficiency, impacting the whole product lifecycle, introducing new business models, changing the working environment, and changing the labour market. As a result, the focus of this essay is on the idea of Industry 4.0, as well as its ramifications and significance.

. In this study, chitosan, curcumin, and aloe vera gel powder were applied to braided silk sutures in both pure and combined forms, and their effects on braided silk suture features were investigated. The braided silk suture coated with a combination of chitosan, curcumin, and aloe vera gel powder outperformed conventional coated sutures in terms of tensile and knot performance. The braided silk sutures coated with a combination of chitosan, curcumin, and aloe vera gel powder (zone of inhibition 5 mm against E.coli and 8 mm against S.aureus) had greater antibacterial properties than those coated with pure forms (zone of inhibition 5 mm against E.coli and 8 mm against S.aureus). The aloe vera gel powder and chitosan-coated braided silk suture possesses a 7mm zone of inhibition against E.coli and S.aureus. The friction coefficient of the same is lower than that of different coated sutures. Sutures coated with aloe vera gel powder and combination had lower bending rigidity, but sutures coated with chitosan had higher bending rigidity.
