Co-pyrolysis of Lignocellulosic Biomass and Synthetic Polymer

This project was carried out to determine a simple method to produce high-grade pyrolysis oil by maximizing the use of biomass wastes. In this study, the results of pyrolysis of sugarcane bagasse alone are compared with pyrolysis of sugarcane bagasse and LDPE mixtures. Pyrolysis was carried out in a semi-batch reactor with different temperature range of 350 to 550 oC, different Biomass : Plastic ratio of 9:1, 3:1, 1:1 and 1:3, with heating rate of 20oC/min. The maximum pyrolysis liquid yield of sugarcane bagasse alone was 47.15% at 500 oC. Whereas, when the co-pyrolysis of sugarcane bagasse and LDPE was done yield of liquid product increased to 52.75% with 1:1 blend. The pyrolysis temperature was 500 oC and it was selected based on results from thermo gravimetric analysis of the studied samples. Due to the synergistic effect in the pyrolysis of the biomass/polymer mixtures, higher amounts of liquid products were obtained compared to biomass alone. The physical properties of the liquid obtained were determined by using standard test methods and the chemical composition was analyzed by using FTIR, GC-MS analyzer for its suitability as an alternate fuel

A SURVEY PAPER ON SMS BASED STEGANOGRAPHY

ABSTRACT: After the advancement in mobile phone industry now mobile phones are available with huge variety of sensors, utility software, entertainment application and services like video conferencing and video call. Mobile phones has become ubiquitous and a general purpose device. SMS is one of the mostly used services in mobile phones throughout the world. Using this service, individuals can write and send to each other short messages and also binary pictures. On the one hand, information security is a critical issue in this digitalized world. For establishing hidden communications, a variety methods have been proposed for covert communications, among which steganography is a relatively new concept. As in mobile phones one can send text messages and binary picture messages both. In this paper, a survey work of all type of Steganographic techniques performed through mobile phone's SMS services esp. text steganography and image steganography and its future scope will be discussed. Most of these techniques are implemented on J2ME (Java 2 Micro Edition) platform

Enhanced dissolution of poorly soluble antiviral drugs from nanoparticles of cellulose acetate based solid dispersion matrices

Polysaccharide-based polymers were used to produce nanoparticles of poorly soluble antiviral drugs using a rapid precipitation process. The structure-property relationships of four novel cellulose acetate-based polymers were studied for their solubility enhancement of poorly soluble drugs. Particles were purified by dialysis, and dried powders were recovered after freeze-drying. The particle diameters were 150–200 nm. The target drug loading in the particles was 25 wt%, and the drug loading efficiencies were 80–96%. The effects of the formulation process and nanoparticle properties on drug solubility were investigated. All nanoparticles afforded increased solubility and faster release compared to pure drugs. Drug release was a function of the relative hydrophobicity (or solubility parameters) of the polymers

IJESRT INTERNATIONAL JOURNAL OF ENGINEERING SCIENCES & RESEARCH TECHNOLOGY A COMPARATIVE ASSESSMENT OF TOPOLOGIES AND THEIR ISSUES IN WIRELESS SENSOR NETWORKS

ABSTRACT A Wireless Sensor Network consists of small, self-configurable sensor nodes, which have very small storage capacity and low processing power. Sensor nodes are scattered over a field and they organize themselves in specific manner automatically to interchange information they sense. The organization of nodes plays a vital role from the point of view of efficiency of network. In this paper, a comparative assessment of WSN topologies is given, which leads the judgment of efficiency of sensor networks

In the present study, extensive surveys were conducted (during 2016–2017) followed with field experiments (2017 and 2019 kharif and 2018 rabi seasons) in the state of Chhattisgarh, India, comprising of three diverse agroecological zones, viz., northern hill zone, central plain zone and southern Bastar plateau zone, for understanding the distribution pattern of viruses and vector populations in prominent pulses and vegetable crops. Field experiments revealed that more than 90% incidence of yellow mosaic disease (YMD) was recorded in mungbean and urdbean, followed by YMD of ridge gourd and bitter gourd, leaf curl disease of tomato (ToLCD) and chilli and yellow vein mosaic disease of bhendi; however, only five per cent YMD was recorded in cow pea. Molecular and sequence analysis of viral genomic components revealed ToLCD in central plain zone of Chhattisgarh was caused by a consortium of begomoviruses, including Tomato leaf curl New Delhi virus (ToLCNDV), Tomato leaf curl Karnataka virus (ToLCKV), and Tomato leaf curl Kerala virus associated with satellite molecules. YMD of mungbean, cow pea and soybean was caused by Mungbean yellow mosaic India virus (MYMIV), while YMD of ridge gourd was caused by ToLCNDV. PCR analysis, using species-specific primers, of samples representing the three different regions revealed that YMD of mungbean, urdbean and cowpea was positive only for MYMIV and was unevenly distributed, while YMD of ridge gourd, bitter gourd, pumpkin and sponge gourd was positive only for ToLCNDV; however, ToLCD was positive for either ToLCNDV or ToLCKV or both, and some samples were also found associated with betasatellite molecules. Amaranthus and rice bean were identified as non-host species for the begomoviruses infecting tomato and MYMIV, as observed by surveys in the hot-spot-like areas, controlled whitefly transmission as well as agroinoculation. Compilation and analysis of available information on begomoviruses affecting these crops in India suggest that they are unevenly distributed in India. This is the first report of the begomovirus occurrence in pulses and vegetable crops in this agroecologically diverse region.Not Availabl
