Development and Characterization of Cardanol Based Polymer Reinforced Fibre Bicomposites

The emerging quest for optimal use of naturally obtained resources through advanced technigues and products has escalated research and exploration of naturally oriented renewable materials. In present investigation, cardanol, obtained from cashew nut shell liquid CNSL , was utilized as base material for a thermosetting polymer TP development. Furthermore, rice husks flour RHF was utilized as reinforcement for the TP. The fabricated biocomposite was characterized for microstructure, thermal behavior and biodegradability. Results from DSC and TG analysis revealed that the sample filled with 5 wt. NaOH modified RHF demonstrated most superior thermal stability, and tensile strength. Moreover, results from FESEM revealed uniform dispersion, and bonding to polymer matrix. Enhanced biodegradability was realized from NaOH modified RHF filled biocomposite post 90 days of monitored soil tests. Therefore, the cardanol obtained TP and biocomposites demonstrated good prospects for application in the electronics, automotive and furniture industry.

Study on Behaviour of Permeable Concrete in the Utilization of Chemical Processing of Ash

Permeable concrete is a distinctive kind of concrete with excessive porosity used for concrete flat work functions that enable the water from precipitation and different sources to ignore without delay through, thereby decreasing the runoff from a web page and permitting floor water recharge. This porosity is attained via a surprisingly interconnected void content. Typically permeable concrete has little or no pleasant mixture and has simply adequate cementing paste coat the coarse combination particles whilst maintaining the interconnectivity of the voids. Permeable concrete is historically used in parking areas, areas with excessive traffic, stroll methods in parks and gardens, residential streets, pedestrian walkways and inexperienced houses, basketball and volley ball courts etc. Porous concrete is an essential utility for the sustainable building and is one of many low affect improvement methods used via builders to defend water quality. The predominant purpose of the challenge is to amplify the mechanical properties. Silica fume and fly ash used as the essential cloth in permeable concrete. Silica fume is a derivative of the ferrosilicon industry, is a relatively pozzolanic fabric that is used to beautify mechanical and sturdiness houses of concrete. This experimental learn about on engineering homes of permeable concrete the use of silica fume and fly ash alternative of cement. The concrete specimen have been examined for compressive strength, flexural strength, break up tensile test. Compressive power accelerated in substitute of silica fume and fly ash content.

Decentralized Finance On Blockchain and Smart Contract Based Financial Markets

The term decentralized finance DeFi refers to an alternative financial infrastructure built on top of the Ethereum blockchain. DeFi uses smart contracts to create protocols that replicate existing financial services in a more open, interoperable, and transparent way. This paper highlights opportunities and potential risks of the DeFi ecosystem. I propose a multi layered framework to analyze the implicit architecture and the various DeFi building blocks, including token standards, decentralized exchanges, decentralized debt markets, blockchain derivatives, and on chain asset management protocols. I conclude that DeFi still is a niche market with certain risks but that it also has interesting properties in terms of efficiency, transparency, accessibility, and compos ability. As such, DeFi may potentially contribute to a more robust and transparent financial infrastructure.

Design and Performance Analysis of a LCD Laboratory Lantern

This paper presents the performance of a LCD laboratory lantern designed to combust varieties of biofuels. The burner was designed as a laboratory scale standard model for experimental purposes. The effect of biofuel atomization on the temperature and structure of flame in the near burner region of a multi fuel stabilised burner of a laboratory scale lantern was investigated experimentally with the help of a microcontroller made of pic 16F877. The laboratory scale lantern is of two litres capacity and was designed and constructed at the department of Mechanical Engineering, Nnamdi Azikiwe University to be used for laboratory combustion analysis, such as flame stability, temperature, height etc with the help of microcontroller made of pic 16F877 which takes temperature reading between 0 150oC and content of flame in order to determine its structure. A 16 by 2 liquid crystal display was used to read out the values of the temperature read by the LM35. The LCD was interfaced to the microcontroller in a 4bit mode. The LM35 Temperature Sensor used in this design has Zero offset voltage, which means that the Output = 0V at 0 Â°C. The design of the fuel level detector unit was achieved using BC548 NPN transistor connected via collector to the microcontroller unit. The burner was designed to atomize and ignite a combination of gaseous, liquid and biofuels. Detailed fuel flow rate and flame temperature measurements were obtained by means of a regression model and a LM35 thermocouple. The measurements aim to provide additional understanding on the efficiency and combustion process interaction in laboratory scale burners which can lead to useful conclusions about the properties and structure of flames produced from different biofuels to ascertain their different areas of industrial applications.

Personal Health Record Management System

Good health is one of the most valuable resources for a human being. Large scale technological advancements have significantly improved human health by a large margin. But there are still several diseases whose symptoms are highly painful and debilitating for a patient. The doctor is in charge of facilitating an effective diagnosis of the patients illness and providing relief to the patient through various medications. For this purpose, the doctor has at his disposal repository of information in the form of PHR or Public Health Records which can be utilized for querying the symptoms experienced by the patient. Sometimes the Medical Institute does not have the PHR with the exact parameters and symptoms described by the patient. Due to the deficiency in the PHR database, the doctor can employ the use of a data aggregator or vendor for fulfilling the requirement from other medical institutions. The problem in this approach is that there is a lack of trust between the medical Institutions and the data aggregators, as PHR can contain sensitive and personally identifiable information that cannot be shared easily. Therefore, this Publication details the implementation of an effective access control mechanism through the use of the distributed blockchain framework along with the introduction of K means clustering and entropy analysis catalyst by the artificial neural network to alleviate the trust issues. Extensive experimentation on the proposed methodology has confirmed its superiority in comparison to the conventional approaches.
