Technology has evolved drastically over the past few years and one part of computers and technology is social networking platforms which give people the opportunity to connect and interact easily. The usage of social networking platforms is increasing daily as an educational system on various levels. The aim of this paper is to examine the role of social media in as e-learning educational tool. The article also determine and explores the similarities, features and differences that learning management systems and social media provide to serve as e-learning tool in online education. Moreover it examines students and lecturers' attitudes towards sharing their ideas and knowledge on social networks as online learning platforms.

This paper presents the results of colour removal from aqueous solutions of textile dye namely C.I. Acid Blue 45, Azo group by adsorption onto preformed flocs of Ferric Sulphate, Manganese Sulphate and Manganese Chloride. Agitated non-flow batch kinetic and isothermal equilibrium experiments were conducted and the experimental results revealed the potential of preformed flocs in the removal of colour of dye. Dye responded favorably and exhibited good to excellent colour removal of Ferric sulphate at pH of 4 and Manganese chloride, Manganese sulphate at pH of 10. The maximum colour removal of Ferric Sulphate, Manganese Sulphate and Manganese chloride flocs was 90%, 85% and 65% respectively. Isothermal equilibrium adsorption data fitted well to Langmuir model representing formation of a unimolecular monolayer of dyes over a homogeneous surface of uniform energy.

The distribution of microscope remaining oil is of great significance to select Reasonable improve oil recovery technology. ased on chromatically theory,the color information of each pixel in the image of rock fluorescence sheet were extracted and put into CIE chromatically diagram, The parameters such as wavelength, brightness, color saturation and difference of red and blue were calculated with the diagram. Then the discriminate functions of the rock, oil and water were constructed and the criteria for the classification of three components was determined, then initial quantitative division of three components from fluorescence sheet was achieved. It's concluded that there is good Relevance between micro oil saturation and color saturation, so according to the oil colors in different positions of fluorescence sheet image, micro oil saturation can be calculated, then ultimately determine the exact proportion of the rock, oil and water in fluorescent sheet. By using the methods mentioned above oil displacement efficiency is calculated with the fluorescent sheet image from cores of displacement experiment in laboratory, comparison results show the accuracy of the method. Compared with the conventional estimation methods, the method can be easily and quickly to quantitatively analyze the image of fluorescence sheets, and it can eliminate artificial disturbance.it is more accurate. The methods can be used to identify distribution of microscopic remaining oil and provide technical support for formulating enhanced oil recovery measures.

This paper presents the study of Three-phase Three-Level inverter topology fed Asynchronous motor drive. Three-level configurations are realized by Diode clamped and Improved multilevel inverter topologies. The poor quality of voltage and current of a conventional inverter fed induction machine is due to the presence of harmonics and hence there is significant level of energy losses. The Multilevel inverter configurations are used to reduce the harmonics by means of synthesizing the output waveforms. The inverters modes of operations are discussed under single phase one leg voltage circuit analysis. The three-phase asynchronous motor is analysed under a split-single phase asynchronous motor. The higher levels can be modulated by comparing a sinusoidal reference signal and multiple triangular carrier signals by means of pulse width modulation technique. The simulation of three-phase three-level inverters fed induction motor model are done using Matlab/Simulink. The results of rotor currents, stator currents, rotor speed, electromagnetic torque and three-phase output voltages are plotted. Furthermore, the numbers of circuit component counts in different inverter topologies are obtained.

Plasma gasification in waste to energy is one of the novel applications that were introduced many years ago. Landfill releases methane which is 21 times more dangerous as a greenhouse gas than carbon dioxide while Incineration which is often pushed as an alternative to land filling is known to produce ashes contaminated with heavy metals and unburned chemicals which are buried in landfill or dumped in the environment. Rather than making waste disappear, incinerators create more toxic waste that pose a significant threat to public health and environment. Sustainable and successful treatment of MSW should be safe, effective, and environmentally friendly. In this application, reactor gasifies the carbon-containing materials in thewaste to produce synthesis gas (syngas) composed primarily of carbon monoxide and hydrogen, which can be used to produce energy through reciprocating engine generators - gas turbines and steam boilers in integrated plasma gasification combine circle (IPGCC), and/or liquid fuels. The in-organicwaste materialsare vitrified and runs out of the vessel's bottom as glass-like slag and reusable metal. The benefits of waste management and energy generation are realized from the process.

In this paper, the dynamical behavior of some eco-epidemiological models is investigated. Preypredator models involving infectious disease in prey population, which divided it into two compartments; namely susceptible population S and infected population I, are proposed and analyzed. The proposed model deals with SIS infectious disease that transmitted directly from external sources, as well as, through direct contact between susceptible and infected individuals. in addition to the infectious disease in a prey species, predator switching among susceptible and infected prey population . The model are represented mathematically by the set of nonlinear differential equations .The existence, uniqueness and boundedness of this model are investigated. The local and global stability conditions of all possible equilibrium points are established. Finally, using numerical simulations to study the global dynamics of the model .

In spite of rapid development of industry energy, biomass remains standard energy source in rural and conventional segments and helps a third of India's energy. Developments like biogas and enhanced cook-stoves exist in India since a large portion of a century. The national biomass approach however has two decades of history, exuding with the local energy policies. The biomass methodology was multi-pronged. It concentrated on enhancing effectiveness of conventional innovations, enhancing supply of biomass advances to give concrete energy presidencies at intensive costs and constructing institutional support. While there is settlement on the requirement for a sustainable biofuels industry, there is little consensus on the most proficient method to continue to evade ecological and social degradation with worldwide biofuel generation. This research paper conducts a literature review of biomass resources and bio-fuels industries in India. Other data collection will be done through literature surveys of existing studies and industry detailed analyses of India, and also stakeholder feedback, on the substance of the SIBD.

This paper concerned with the heat transfer behaviour of aqueous suspension of nanoparticle i.e. nano fluid, a procedure for preparing a nanofluid its importance, application and challenges of nanofluid. Apart of these the theoretical study of the thermal conductivity of nanofluids is introduced. Some factors such as particle size, particle shape the volumefraction and properties of the nanoparticles are discussed. A theoretical model and empirical equation for the effective thermal conductivity of Nanofluid is proposed to describe heattransfer performance of the nanofluid.
