The main purpose of the present study is intended to establish briefly the role of teachers in facilitating 21st century learning skills for the development of creative insight among learners in inclusive classroom settings. The teachers display a vital role in the academic procedure. Learning can ensure anytime, wherever, and the places where this learning happens are extremely and progressively diverse. Educational systems are undergoing a pattern shift in the fight to encounter the requirements of learners in a world that is speedily moving from a technical, demographic, social, and environmentally friendly perspective in facilitating 21st-century learning skills for the development of creative insight among learners in inclusive classroom settings. In modern years, academic systems in the world have also advanced settings with an expanded pressure on emerging the skills, knowledge, and attitudes required for achievement in the 21st century. Teachers are facilitator and cohorts to practice a collective prospect prepared for the safety of persons, societies, and the world. The author made an exertion to share the new viewpoints of 21st-century learning skills to increase for development of creative insight among learners in inclusive classroom settings.

Wireless sensor network (WSN) comprises the distributed sensors for aggregating and organizing the data. Data aggregation is the major concern in WSN since it relies on several factors, namely energy constraints of sensors, network topology, links conditions and so on. The conventional approach does not perform efficient data aggregation due to their battery power of nodes and degrade the network lifetime. To improve data aggregation and network lifetime, An Energy-Efficient Ensembled Elbow Fuzzy C-means Clustering based Data Aggregation (EEEEFCC-DA) method is designed. Initially, residual energy of each sensor node (SN) is calculated. To determine the number of clusters, the elbow method is used in fuzzy c-means clustering algorithm. Then, Centroids value is calculated for every cluster to group SNs. Bray-Curtis Similarity Index is used to compute the similarity between the SN and Centroids value of cluster. SNs are grouped depends on the similarity value. The process gets iterated until every SNs gets clustered to the suitable clusters. After that, the SN with higher residual energy is selected as cluster head (CH). CH gathers data from each SNs and send to sink node. This, assist to enhance the data gathering accuracy and lessen the energy consumption.  Simulation of EEEEFCC-DA method is carried out with various metrics namely energy consumption, network lifetime, data aggregation accuracy (DAA) and data aggregation time with number of SNs and number of data packets (DP). Results show that EEEEFCC-DA method provides better performance in term of DAA , network lifetime , energy consumption and data aggregation time than the conventional methods.

The purpose of this research paper is to obtain access to the teacher effectiveness of secondary school teachers in relation to their gender, location and type of school. For the conduct of the research, the survey approach was used. The Teacher Effectiveness Scale (2010) was created by Dr. Shallu Puri and Prof. S.C. Ghakhar to gather data from teachers in secondary schools. Samples of 130 secondary school teachers from the Jalandhar district of Punjab were randomly chosen for this research. To analyze the results, statistical techniques such as Mean, SD, and t-test were used. The result showed that at both stages of importance, there is no significant difference between female and male high school teachers. There is a significant difference between the effectiveness of urban and rural secondary school teachers at both levels, and there is a significant difference between the effectiveness of teachers among secondary school teachers with regard to the form of institution.

The growth of various types of information happens day by day. The increased production of data, in turn, led to the invention of various data storage tools. The idea of storing data in DNA is now one of the major focuses. There are so many methods for storing data in DNA, the method put forward by Nick Goldman and Evan Birney has so many advantages over the other methods. They had converted data in the binary form into ternary by using improved Huffman coding of base 3. This helped to reduce the error rate that had produced in the earlier works.

Ayurvedic system of medicine includes an important class of drugs of mineral origin under which there is as subclass known as ayurvedic bhasmas. These are derived from metals like gold, silver, copper, iron, lead, supreme medicines due to their extraordinary medicinal properties. However, according to the modern science, heavy metals referred above are difficult to absorb at cellular levels and therefore are toxic and harmful to human bodies. As against this according to ayurved, all these elements, after ayurvedic processes of bhasmikarana not only lose their toxicity but miraculous medicinal properties are induced when they are transformed into what is called as bhasma state. In an attempt to elucidate the exact nature of this bhasma state, we found that a genuine Ayurveda bhasma possesses two characteristics (i) extremely tiny particle size, tending to nano level of the order of 20-90 nm and (ii) attachment of organic components to these nanosized bhasma particles. These findings are expected to be useful to throw light on the medicinal potential of ayurvedic bhasma. On this point of view, this work is concerned with analysis and study of samples of lohabhasma by Infrared spectroscopy method.

The green corrosion inhibitor is used in epoxy coating system by extraction of turmeric in dimethyl formamide (DMF). The major component extracted is curcumin. Three concentrations have been studied for anticorrosive performance i.e., X, 2X and 4X. Among this X based concentration showed the best performance. Magnesium hydroxide Mg(OH)2 has been treated with 3-glycidoxypropyltrimethoxysilane (GPTMS). It was added into coating formulation at three concentrations namely 5%, 7% and 10% (w/w). The best anticorrosive performance has been observed for 5% concentration. As the concentration increases the anticorrosive performance decreases but flame retardancy increases. The 7% Mg(OH)2 concentration has been combine studied with turmeric X concentration. It is observed that combination of extract with Mg(OH)2 gives good anticorrosive performance as well as flame retardant properties. The anticorrosive performance is evaluated by salt spray and electrochemical impedance spectroscopy (EIS) and flame retardancy is evaluated by Limiting oxygen index (LOI) and UL-94 study.

Inspired by recent experiments and theoretical work on vanadium spinels, the least investigated vanadium spinel i.e. NiV2O4 has been explored theoretically in this work. The systems is found to have an optimized vanadium- vanadium distance of 2.94 , which is the same as the limit of itinerancy in vanadium spinels.  This indicates that the system is sitting exactly at the border between metallic and insulating phase. The calculations show that there is no tetragonal distortion present in it and it would prefer normal spinel structure. The DFT calculations have been performed using GGA approximation.
