Life would not be the same without technology. Because of its many practical uses, nanotechnology has recently emerged as the most widely used sector of technology. Nanostructured materials, such as nanoparticles, nanopowders, nanowires, nanotubes, nanorods, nanofibers, dendrimers, nanoclusters, and nanocrystals, are produced in large quantities worldwide because of their potential applications in a variety of fields, including biotechnology, electronics, photonics, medicine delivery, and agriculture. This technique seems to be the solution to the global issues of water and environmental pollution. In addition to the immense benefits of nanotechnology, nanomaterials have negative consequences on human health that must be taken seriously. While some nanoparticles enter the body through the lungs or other organs through food, drink, or medication, they can also affect various organs and tissues such as the kidney, liver, brain, etc. and have cytotoxic effects. Certain nanoparticles can enter the body through breathing and cause damage to lung tissue and chronic breathing problems. The form, size, concentration, solubility, and stability of a nanoparticle all have a significant impact on its hazardous effect and interactions with biological systems. Therefore, it becomes essential to comprehend the risk and expense of any consequent harm while using new technologies. For the sake of society's safety, it is thus essential to research the different nanostructure materials and their human exposure. With an emphasis on their usefulness and toxicity, this paper provides a concise overview of the applications and potential effects of Ag and TiO2 nanoparticles on human health and the environment.

The purpose of the study was to find out the effect of callisthenic training on selected physical variables among engineering students. To achieve the purpose of the study, fifty Engineering students were selected randomly from SRM University, Tiruchirappalli. The subjects aged from 18 to22 years. The selected subjects were divided into two equal groups namely experimental and control groups of 25 subjects each. The training period was limited to eight weeks and for six days per week. The callisthenic training was selected as independent variables and Flexibility and Balance were selected as dependent variable and it was measured by sit and reach, and stroke stand. All the subjects were tested two days before and immediately after the experimental period on the selected dependent variables. The obtained data from the experimental group and control group before and after the experimental period were statistically analyzed with dependent‘t’-test to find out significant improvements. The level of significance was fixed at 0.05 level confidences for all the cases. Significant improvement was found on Flexibility and Balance of experimental group due to the effect of callisthenic training when compared to the control group.

Considerable progress is being made in the field of architecture, particularly when it comes to visual displays. Digital technology is always evolving, affecting the technical side of visualisation that was previously accomplished through modelling, rendering, and sketching methods. This paper presents a brief review of technology applications in architecture. Technologies include, virtual reality (VR) and augmented reality (AR), 3D Printing, Artificial Intelligence (AI) and parameter modelling techniques. Challenges and future scope of research in these technologies for architecture were also presented. Various applications of 3D printing in architectures such as architecture education, design and construction were also presented in brief. The use of AI techniques like, Expert systems, Evolutionary algorithms, Machine learning, and multi-objective optimization in architecture were also presented. Keywords; Virtual reality; Augmented reality; Artificial Intelligence; 3D Printing; Expert Systems; Evolutionary Algorithm.

Rainfall is a prime component in the hydrological parameters in Meerut region. Rainfall is an important factor for various studies like engineering, agriculture, weather, and many more. This article aims to review studies for rainfall trends and variability all over India. Rainfall trends vary at different places throughout the country. Precipitation analysis provides knowledge related to agricultural activities to assess the availability of water and to take proper measures for storage. Non-parametric tests such as Sen’s Slope were used as estimator of trend magnitude which was supported by Mann-Kendall test. Regarding rainfall trend results of different studies shows variation which leads to an unclear picture of rainfall trend. In the study of monsoon of different locations in India some places showed increasing trends however there is signifying decrease in trend allover India. It was also mentioned that analysis can vary from for a location if done using different source or types of collection of data.

The widespread online misinformation could cause public frenzy and genuine monetary harms. The misinformation containment issue aims at limiting the spread of misinformation in online interpersonal organizations by dispatching contending efforts. Roused by sensible situations, we present an investigation of the misinformation containment issue for the situation when a self-assertive number of falls are permitted. This paper makes four commitments. In the first place, we give a formal model for multi-course dissemination and present an important idea called as course need. Second, we show that the misinformation containment issue can't be approximated. Third, we present a few kinds of course need that are as often as possible found in genuine informal communities. At long last, we plan novel calculations for tackling the misinformation containment issue. The viability of the proposed calculation is upheld by empowering experimental outcomes.
