Abstract: As wireless sensor technology improves; an increasing number of organizations are using it for a wide range of purposes. ZigBee technology is a new standard in wireless personal garea after Bluetooth. After an introduction to this technology, a new wireless meter-reading system based on ZigBee protocol has evolved. This system, which is comprised of ZigBee network and database management system, has many important advantages such as low cost, low power consumption, and low date rate. Wireless Sensor Network based on ZigBee technology is a wireless network which is composed of many nodes of ZigBee RF chip, sensor and MCU, especially suitable for application of the remote monitoring system in flammable and explosive environment. Fusion of RFID and Zigbee is also possible which turn out to be boon for wireless sensor network technology. A complete overview of wireless sensor network technology is given in this paper. Wireless sensor network technology has become one of technological basic needs of us.

Abstract. The article deals with the current scientific problems of natural geography related to the development of new pedagogical technologies and their implementation in the educational process. The use of recommended interactive methods in independent study is considered very effective and is a very useful method for students, especially for students who work more on themselves. Today's demand is to make young people talented, intelligent, innovative, as well as mature and well-rounded individuals, as a result of the work carried out in the field of education today. This is how creating tables of different contents and filling them out shows the student's talent and desire for innovation. Also, the techniques and methods necessary for today's student are shown, the role of the teacher in conducting lessons meaningfully, the suitability of the method used by the teacher for the lesson, factors affecting the quality of education and natural issues of the use of methods based on the specific features of geography are highlighted.

Abstract: Adsorptive removal of environmental contaminants, using agricultural wastes, have proved to be cost-effective, sustainable and ecofriendly. This study experimented the biosorption of methylene blue dye (MBD) from aqueous solution using a treated plantain stalk biomass as adsorbent. 300 g of powdered plantain stalk biomass was treated with 1.0 M NaOH which was used as the experimental adsorbent in the batch studies. The surface area characterization of the NaOH-modified plantain stalk (nMPS) biomass was studied using Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM) both before adsorption and after adsorption. The effects of contact time, adsorbent dosage, initial dye concentration, and pH on the adsorption efficiency were examined. The result of the batch adsorption revealed that the optimal adsorption temperature is 30 0C, beyond which the adsorption efficiency drops considerably. The increased in pH from 4 to 10 favored increased adsorption, suggesting that alkaline media best facilitate nMPS adsorptive capacity. The adsorption was favored by high concentration of MBD. The FTIR surface area analysis of the nMPS suggested the presence of functional groups like; -OH, C-O, CN, C=O, N=C=O, O-H, C-C and C=C. The presence of these functional groups was afforded by the NaOH modification of the adsorbent material which gave an adsorption efficiency of 94 %. The SEM results also revealed changes in surface area structures before and the adsorption experiment. Thus, the findings demonstrate the potential of NaOH-modified plantain stalk biomass as a sustainable and efficient adsorbent for textile wastewater treatment.

Abstract: Various materials have been used to remove environmental contaminants for decades and have been an effective strategy for environmental cleanups. The current nonrenewable materials used for this purpose could impose secondary hazards and challenges in further downstream treatments. Biomass-based materials present viable, renewable, and sustainable solutions for environmental remediation. Recent biotechnology advances have developed biomaterials with new capacities, such as highly efficient biodegradation and treatment train integration. This review systemically discusses how biotechnology has empowered biomass-derived and bioinspired materials for environmental remediation sustainably and cost-effectively.
