Influence of Metakaolin and steel fibers on stress strain behavior of concrete
Authors: Chandak Mayuri , Pawade P Y 
Published: June 2021

Abstract
This article describes the effects of different proportions of metakaolin and steel fiber on the stress-strain behavior of concrete. Concrete has become an important part of infrastructure development due to its wide and wide application. However, its brittleness can cause cracking, and cause some deterioration problems and infrastructure failures. Considering the problem of cracking performance, researchers around the world have conducted various studies to develop concrete with higher performance, longer life, and minimized destructive effects on nature. In order to obtain such characteristics, researchers only focus on the improvement of strength. It is observed that the higher compressive strength can make the substitution rate of metakaolin 16% and that of steel fiber 1.5%. Although the published literature provides some theoretical models and a large amount of experimental data on the compressive performance of fiber-reinforced concrete, there are still considerable reservations about the applicability of these models in design. Stress-strain curve is required for correct design and repair. This article introduces the results of compression tests of steel fiber reinforced concrete carried out in accordance with standard procedures, and rigorously evaluates the proposed model to define compressive stress-strain behavior. The reported test was performed on cylindrical specimens of plain and steel fiber reinforced metakaolin with fiber content of 0.5%, 1.0% and 1.5%. The concrete grade considered in this study is M40.

The nature of catalytic species in the Wacker oxidation process-A review
Authors: Imandi Venkataramana , Puri Prafulla , Korde Vivek 
Published: June 2021

Abstract
The catalytic structure of the Wacker process is matter of debate. It is monomer or dimer complex in the Wacker oxidation of ethene. In this paper, we studied catalytic nature of the Wacker oxidation process. We employed rare event technique such as metadynamics simulation. We used Pd-Cu and Pd-Pd dimer complex as the initial structure. Our simulations show that Pd-Cu and Pd-Pd dimer complexes are getting hydrolysed to give monomeric complex. The barriers of Pd-Cu and Pd-Pd dimer complexes to hydrolysis are lower than the reactions with ethene ligand. Hence, the nature of catalytic complex in the Wacker oxidation is the monomeric complex of Pd.

Authors: Mandal Naba Kumar , Rao Y R M 
Published: June 2021

Abstract
Heavy metals which are discharged from industries in the environment with wastewater causes serious problems for the living organisms. To save the water bodies from the heavy metal contamination, many treatment processes are there. But most used is Adsorption processes where Activated Carbon is used as Adsorbent. As the activated carbon is costly, the treatment is expensive. So, low-cost alternate adsorbents are to be identified in the present scenario. The locally available agro waste material namely Teak Leaves (botanical name is Tectona Grandis) is used as low-cost adsorbent Teak leaves (TL) with pretreatment have been used to study for their potential use to remove chromium (VI) from wastewater by Adsorption. Contact time, Adsorbent dose, pH, initial Cr (VI) ions concentration and particle size have been studied for batch process. The optimum pH, agitation time, Cr (VI) ions conc. adsorbent dose and particle size were found 2.0, 75 minutes, 175 milligrams/l, 25 gm./l and 150 – 300 microns respectively at the room temperature (30 ± 2° C) and achieved 69.1 % to remove Cr (VI). Whereas, the powdered activated carbon (PAC), the removal was 78% at optimum conditions 2.0, 60 min, 125 mg/l, 15 gm/l and <75 micron respectively. The adsorption equilibrium data was used to fit into, Freundlich, Langmuir and modified Freundlich isotherm. But Freundlich isotherm fitted well compared to other two. A distinct advantage of TL as bio-sorbent is that these are locally and easily available agricultural waste and can be used with minor chemical treatment. This process is cost effective and eco-friendly.

Published: June 2021

Abstract
Bio-mimicry is one of the leading fields of research that has been around since the early ages of science. Aerospace industry, especially, takes most of its design inspiration from the aquatic life. In this paper a breed of flying fish scientifically known as Exocoetidae, Cypselurus Hiraii has been chosen to study. The aerodynamic characteristics of the fish were studied experimentally in a wind tunnel previously, but the plausibility of its design application in the aerospace industry hasn’t been explored yet. Therefore, in the present study the cross-section of the fish in the side view has been traced and its aerodynamic performance as a 2D infinite wing has been examined in ANSYS R15 (FLUENT). The performance of this fish inspired shape has been compared to the properties of conventional aerofoils in terms of coefficient of lift and coefficient of drag.

Abstract
We come across many disabled people in NGO’s and hospitals. These people find difficult to convey message as they cannot make full body movement like normal people. Looking at such condition we tried to make a system which can be used to convey messages on behalf of such people. This system give different messages by simple movement of hand of the person. The device is placed on person’s hand so the he can tilt it in particular direction. By tilting the device in different direction in a specified range of angle different messages are displayed. Here an accelerometer is used to measure the tilt. The data from the accelerometer is then passed to the microcontroller. The microcontroller takes the information, process the data and shows the particular message depending on the tilt by the person. The microcontroller send data to a LCD screen and desired message is displayed. On the receiver side along with LCD screen a buzzer is also present and in gets on as soon as it receives signal from the accelerometer. On person’s hand the device consists of an RF transmitter which is used to transfer the data signal in encoded form. On the receiving end the RF receiver gets the data from the transmitter and then decodes it and which is then passed to the microcontroller for reading the data, processing the data and responding to it.

Abstract
Cloud computing offers subscription based storage and resources. Cloud computing provides various services to cloud users. Increased use of information and communication technologies (ICT) has led to increase energy cost as well also increased emission of greenhouse gases like CO2. Since energy is an important asset, green cloud computing comes into picture. Green cloud computing can be achieved by applying various approaches, which uses lesser power as well as emits less CO2 gas, which is hazardous to environment. Energy efficient technologies results in decreased overall energy consumption. There is a need of data centre in almost every field like web applications and businesses which results in producing huge amount of CO2 in environment. To make data centres environmental friendly we need energy efficient approaches which will reduce energy consumption and there hazardous effects on environment. Data is being generated at very high speed so the need of data centres will also increase. Increased data centres will then consume more amount of energy. The main objective of these paper is to reviews various approaches applied by researchers to make energy efficient cloud computing.

This motivates us to introduce the new type of differential form by using second fundamental metrical tensor. In this paper, we have introduced the RP-harmonic integral, Modified RP-harmonic integral and Generalized harmonic integral. By using the period matrix corresponding to the RP-harmonic integral, Modified RP-harmonic integral and Generalized harmonic integral, we have studied the numerical invariant of a manifold M. As anologous to geometric genus of a surface, we have defined invariant of a surface, we called as RP-geometric genus Prp

Abstract
The risk of cyber-attacks on a country has grown drastically. The cyber security risks against critical power infrastructure seem to be worsening. Obviously, any sort of assault on an atomic plant is very concerning. An attack that allows hackers to manipulate the system that control a nuclear reactor, while very difficult, could have very serious consequences. The main reason for this attack is vulnerabilities in local computer networks in power plants. Which has direct access to the internet without any major protection against cyber-attacks like phishing attacks against power plant employees, virus injection tools etc., As the main defense against this attacks is to make power plant networks and employees anonymous to the internet and making sure that no one is tracking the employees which can lead to loss of sensitive information of the plant. The Tor onion networking protocol is best suitable for these types of attacks on employees and computer networks in the power plant. Since providing Tor network for individual employee in practically impossible. Our projected work aims to establish an onion router which provide overall coverage of computer systems and employees which has access to power plant inside the perimeter of power plant. To simulate the plant local networks we construct an internet router using raspberry pi which is configured with Tor onion routing protocol access the internet by computers connected to our Router.

Published: June 2021

Abstract
The aim of this work is to investigate the time fractional thermoelastic state of a thermally sensitive functionally graded thick hollow cylinder subjected to internal heat source. Convection boundary conditions are applied on the curved surface of cylinder also sectional heating is assumed on the lower surface. The material properties except density and Poisson’s ratio are assumed to be dependent on temperature. Kirchhoff’s variable transformation is used to reduce the nonlinear heat conduction with temperature dependent thermal conductivity and specific heat capacity to linear form. Further the solution of linear form is obtained by using integral transform technique in the form of Bessel’s and trigonometric functions. All physical and mechanical quantities are taken as dimensional for the theoretical analysis whereas for numerical computations non-dimensional parameters are assumed. Numerical results of temperature change and stress distribution are illustrated graphically for ceramic-metal-based functionally graded materials and shown in figures with the help of Mathematica software.
Study of influence of tool geometry and temperature on bone substructure to reduce bone drilling injury
Authors: Dahibhate R V , Jaju S B 
Published: June 2021

AbstractFor multiple piece bone fractures orthopaedic surgeons often prefer bone drilling. During bone drilling (cortical and cancellous) heat is generated. Heat accumulation above tolerance level of bone biomaterial causes permanent bone injury. This leads to delayed restoration period. This can be avoided by controlling drill tool geometrical aspects and in depth information of bone substructure. Among various angles of drill tool, helix angle is very important as it gives way out to bone chip and thereby heat removal from drilling site. Temperature affects bone up to cellular level and so to identify thermal damage, bone substructure has to study. This paper deals with the study of drill tool geometrical aspects that contributes to temperature rise and its effect on bone substructure.
