New products and materials innovations are rapidly owned by fast developing industries and smart startups. Automation in industry has taken out many jobs but has given opportunities for diversification. Evolution of the new technologies helps in improvement of global economy. Sustainable developments aim for self-reliance and technically acceptable. Sustainability may be understood as such development which meets the needs of the present without compromising the ability of future generations to meet their own needs. It is well understood that earlier development consumes vast quantity of natural resources without caring of negative impact on environment upon which they depend.

Cadmium is biopersistant. Significant concentration of cadmium is released in the environment by various industrial activities worldwide. Therefore, removal of cadmium from waste water is now receiving greater attention from researcher various techniques for cadmium metal removal from industrial effluents has been developed. These techniques are: chemical precipitation, chemical reduction, ion exchange, evaporation, membrane processes, and adsorption. Each method has its own advantages and disadvantages among these techniques; adsorption of cadmium metal by using various materials was proved to be a very effective method. Moreover, research is needed to find the commercial and practical utility of low-cost adsorbents.From the current review, adsorption seems to be t he best alternative, help to develop new metal remediation technology and to study the scientific advances of recent years in this area.

Forecasting is a broad research domain for multidisciplinary researchers. Forecasting climatic conditions is a challenging task that is carried out by scientists around the globe. The researchers for Forecasting of the various climatic phenomena have used multiple architectures of Artificial Neural Networks (ANN). Such tasks demand huge analysis on recent and past results to give appropriate with precise results of the forecast. The RBF network has a single hidden layer, simpler structure as well as a much faster training process; therefore, it is a popular alternative to the other ANN architectures. In this paper, we are proposing a Radial Basis Function Network (RBFN) as a machine learning tool for making forecasting. In a variety of real-time packages, that includes the prediction of weather, load forecasting, forecasting approximately a variety of traveller and in various programs RBFN applied.

Liquefied Petroleum Gases [LPG] are flammable mixtures of gases such as propane and butane mainly which is transported and stored in liquid phase in storage vessels under amply pressure. These industrial processes are of high fire and explosion hazard. When a vessel carrying LPG is damaged, an abrupt drop in pressure may release colossal quantities of evaporating gas and energy that has a destructive effect on the vessel itself and its surroundings. When comes in contact with ignition source, BLEVE phenomenon is developed. Elevated temperature environment outside the LPG pressure vessel can cause vessel explosion due to the pressure mount inside the tank and drop in strength of the tank walls. This catastrophic rupture will lead to BLEVE phenomenon which when ignited will again lead to a vapor cloud explosion. Most common scenario is when the pressure vessel partially filled with liquid form of LPG is exposed to a fire. The primary focus of the paper is to analyze the LPG storage pressure vessel under thermal loading condition. For this Finite element modeling approach is used and the analysis is carried out in ANSYS TM software.

Friction stir welding (FSW) broadly used in the same grade as aluminium alloy but for aluminium alloy material it requires high speed rotation of FSW tool which develops high temperature on tool. In this paper process parameter of FSW are studied based on the strength of welding joint and predict FSW tool speed as low as possible according to the past literature. Constant machining parameters are tool rotation of FSW is 800 rpm and welding speed 15 mm/min. In this work analysing the strength variation of welding joint under two mode of pre-heating temperature on the work-piece then variation of cooling medium apply after preheating to change the grain structure of work-piece. In this work the FSW process is passed over two pieces of aluminum at once and the effect of tool rotation and temperature of the tool is discussed by preparing the sample for testing according to the ASTM dimension.

Herein formation of pure In2O3 thin film for OLED material is reported. Synthesis and characterization are reported inside the manuscript. PL spectra were recorded for ultraviolet radiation and it shows down-conversion with emission peaks centred at 448 nm (Blue Region), 513 nm (Green Region) and 609 nm (red Region). For this emission spectra CIE coordinated are plotted and found to touches white light boundary with enhance blue emission. For CIE coordinate value of x = 0.27, y = 0.28 are found. The colour rendering index and co-related colour temperature are calculated for its practical/industrial ability. Thermoluminescence glow curve analysis of prepared pallet and it is found good TL glow curve response with UV dose. Now as formed thin film may be useful for energy efficient photovoltaic application.

For nitrogen analysis first and second soil samples were collected around the power plant and sponge iron plant of Siltara area, the third soil sample taken from crop area around rice mill of Bemetara district (India). Samples were collected from 15 cm. depth during post monsoon 2018. Result of chemical analysis of these samples indicates that the soil sample is found to be nitrogen deficient. Sample collected from 50 to 4500 meter around rice crop field. Available N content was raised continuously from 221.79 kg ha -1 (50 m) to 293.42 kg ha -1 (4500 m.) around sponge iron industry, 233.11 kg ha -1 (50 m) to 302.13 kg h -1 (4500 m) around power plant industry and 200.70 kg ha -1 at 50 m and 335.23 kg ha -1 at 4500 m around rice mill industry. This analysis is done by Nitrogen Auto Analyzer. Maximum value of nitrogen with phosphorus - potassium uptake observed in 150 kg of N ha -1 which is available in five split as 6S (10:10:10:20:05 at 11-13, 10, 30, 50, DAS & FL) and the concentration of higher soil available nitrogen also observed in 150 kg of N ha -1 described in following five split as 6S (10:10:10:20:05 at 11-13, 10, 30, 50, DAS & FL), maximum soil available phosphorus - potassium was observed in following three split as 1S (10:40:20 at 0, 20, 50 DAS) applied in 100 kg of N ha -1 .
