Using of chemical admixtures like lime, cement, bitumen in soil stabilization are highly expensive in now a days. However, egg shell powder and common salt are could be preferable replacement in case of these manufactured materials as they are cost reducing. This research investigates an experimental study for stabilizing a clayly soil with eggshell powder as a replacement of industrial lime as well as the engineering properties of soil. Stabilization was performed at optimum eggshell and with 2, 4, 6, 8, and 10% of common salt. The addition of common salt reduced the Plastic Indices (PI) of the samples. The values reduced from 14.82, 11.11 and 7.99% to 8.03, 1.25 and 1.23% in samples A, B and C respectively. The unsoaked CBR values also increased from 34.78 to 50.99 kN/m2, 15.64 to 28.89 kN/m2 and 27.31 to 34.20 kN/m2 at optimum stabilization in samples A, B and C respectively. The result showed that the addition of common salt improved the compaction and CBR characteristics of eggshell stabilized soils. Moreover, it is observed that curing duration had significantly improved the strength properties mentioned of the stabilized soil samples.

Plastic waste is generated from industrial as well as domestic sectors. Since plastic is non-biodegradable, the management of plastic wastes especially in urban areas are a major cause of concern in today’s world. Mostly, the plastic waste comprises of poly ethylene, poly propylene, poly styrene. The softening point of these compounds varies from 1100ºC to 1400ºC and no harmful gases are produced. Softened plastic has got an unique property of forming a coating around aggregates. This aggregate coated with polymer (ACP) when mixed with different grades of heated bitumen can be used for the construction of flexible pavements, where plastic acts as a raw material. It makes highly durable pavements with nil pothole, waterproof and reduces the amount of bitumen required by up to 10 kgs by weight. This paper intends to present the various steps involved in the procedure of such plastic road construction, points to be cautious while using the plastic waste, ecological situations withstanding the steps. The strength of roads achieved can be 100 percent.

Remote areas by their geographical inaccessibility or location in hostile/foreign territory present numerous challenges in their mapping despite advances in the field of remote sensing. The primary challenge still remains in achieving reasonable accuracy standards in locational and feature extraction domains. The plethora of open domain RS and GIS resources present us with a credible feasibility of obtaining information to generate mapping products. This research is an attempt to identify, utilize and assess quantitatively and qualitatively the open domain resources in mapping of remote inaccessible areas. The research identifies various open domain resources for obtaining Ground Control Points (GCPs), images and GIS data both physical and cultural for mapping requirements. On the quantitative assessment aspect, the location intelligence obtained in the form of GCPs has been verified using field verification. The research has been instrumental in arriving at robust methodology of online DGPS processing without uploading own sensitive raw GNSS observation data in the open domain.

Construction waste is growing expeditiously with the dramatic increase in the number of demolitions of old constructions across the world. Therefore, it has led to social as well as environmental concern in recycling process of the construction waste. The material used extensively for construction across the world is concrete and mostly it has been incorporated in all kind of civil engineering works. Since, 70-80% of the concrete volume comprises of aggregates, it will be judicious enough to utilize the recycled aggregate again. Based on the report of researchers, it can be concluded that recycled aggregates from concrete is acceptable for non-structural construction works. In this paper, a comprehensive investigation has been conducted by testing of the properties of the recycled aggregates and studying the results. Basic properties such as compressive strength, flexural strength, Split tensile strength are explained here for different combinations of recycled aggregate with natural aggregate. Study has shown that the strength of concrete using partial proportion of recycled aggregates could reach substantially similar strength compared to concrete having freshly used natural aggregates. Substantially, prevailing status of recycled aggregate in India along with its need about the time ahead and its prosperous implementation are discussed here.

This paper will examine Georges Prosper Remi’s (pen name Herge) representation of India in Cigars of the Pharaoh (French: Les Cigares du Pharaon), the fourth volume of The Adventures of Tintin, by this Belgian cartoonist. It was published in Le Petit Viengtieme, the children’s supplement of the conservative Belgian newspaper Le Viengtieme Siècle which was serialized weekly from December 1932 to February 1934. I shall argue how India has been (mis)represented by Herge in this volume. For instance I shall try to see how Herge looks at India in a postcolonial exotic manner. I shall try to examine was India really like this in the 1930s when Herge writes and publishes this volume and I shall also investigate the impact of Tintin comics on Indian minds.

Aromatic compounds present in soil can be degraded by catechol dioxygenases. They degrade these aromatic compounds present in soil mainly by two processes, intradiol and extradiol process. A brief account of the processes along with developments in this area are presented in this article.

The level of nonlinearity in the dynamics of the daily mean air temperature data series over Michigan Grate Lake has been examined using appropriate statistical tools. The time series is collected from the database of Tides and Currents under the National Oceanic and Atmospheric Administration (NOAA), Menominee, MI, Station ID: 9087088, length 1584 days from 14th March, 2011 to 14th July, 2015 for this purpose. The raw data has been pre-processed using simple exponential smoothing and discrete wavelet transform (DWT) based denoising. To gauge the extent of nonlinearity under the dynamics of the test series, delay vector variance (DVV) strategy is applied. The study yields that the fluctuation of daily mean air temperature over Michigan Great Lake poses deterministic, regular, non-linear behaviour in the temporal domain.

The Smart Solar EV Charging Station is a cutting-edge technology that integrates solar energy with electric vehicle (EV) charging capabilities. This system uses solar panels to generate electricity that can be used to power the charging station, reducing the reliance on the grid and providing a sustainable and cost-effective solution for EV charging.

This paper presents the generalized mathematical modelling and state space model of dc motor. The performance of dc motor under various conditions is simulated using MATLAB/SIMULINK environment and simulation result demonstrates the feasibility of the proposed system.

In the present era of Internet of Things (IoT), data driven decision making is getting much acceptability in industrial and agricultural sectors. Increase in world population and reduction in resources for agriculture have challenged the conventional farming method to optimize the utilization of resources in a statistical way. Therefore, different field parameters need to be collected and correlated to decide the optimum amount of resource to be applied. Estimation of field parameters are possible by visually comprehending the variation in color gradient or by applying multiple specialized sensors for different parameters at the field. Estimation of physical parameters, field parameters and environmental parameters with required accuracy helps to determine the accurate amount of the resource to be applied. Optimization of resources is the key requirement in the present situation which is not possible without the appropriate sensors. In this paper different types of sensing mechanisms have been discussed with their pros and cons to highlight the potential research challenges in current sensing technology.
