Controlling SO2 by Using Low Cost Adsorbents
Nenavath Gandhi,V. Mary Priyanka,D. Sirisha
Environmental Research, Engineering and Management , 2013, DOI: 10.5755/j01.erem.62.4.1947
Abstract: Sulphur oxides are formed during high temperature combustion processes from the oxidation of sulphur in the air. The principal source of sulphur oxides is sulphur oxide (SO) and sulphur dioxide (SO2), collectively known as SOx. SO and SO2 concentrations are therefore the highest in industrial area. Other important sources are power stations, heating plants, and industrial processes. Long-term exposure to sulphur dioxide may affect lung function, and that exposure to sulphur dioxide enhances the response to allergens in sensitized individuals. The feasibility of using waste materials as adsorbent for air pollutant SOx was evaluated in the present study. The experiments were carried out in laboratory on certain waste materials like Neem leaf powder, orange peel powder, custard apple leaf powder, Horse gram seed powder, Ragi seed powder, mango bark dust, mixed algae, and Neem bark dust. The experimental investigations were carried out by traditional adsorption studies, and they showed that all substances had certain capacity to adsorb SOx from aqueous solution of SOx. The order of adsorption by different low cost materials is Mango bark dust > Orange peel powder >Custard apple leaf powder> Neem leaf powder> Horse gram seed powder> Ragi seed powder> Neem bark powder, mixed algae by 98%>95%>88%>82%>80%>78%>77%>74%, respectively. At lower concentration the adsorption is more compared to higher concentration. It is found that the adsorption increases with an increase in surface area.

Transmission System Reconfiguration to Reduce Losses and Cost Ensuring Voltage Security  [PDF]
Veerapandiyan V., Mary D.
Journal of Power and Energy Engineering (JPEE) , 2016, DOI: 10.4236/jpee.2016.46002
Abstract: The aim of this paper is to reduce the losses, total generation cost by switching of transmission line and to maintain voltage security under N？- 1 contingency conditions. Generation cost is calculated and the priority list is made for switching the line. The problem is solved by ACOPF using Interior Point Method. In order to test the feasibility and effectiveness of the above method, a sample 6-bus system and IEEE 30-bus system have been used. The impact of switching on system parameter includes the generation cost, locational marginal pricing (LMP) and transmission losses, ensuring voltage security of the system.

TUMOR INDUCTION STUDIES IN DROSOPHILA MELANOGASTER USING TRYPTOPHAN

Abstract: Tumor cells have an altered amino acid metabolism. They express high levels of tryptophan and L-arginine metabolizing enzymes. This leads to depletion of tryptophan and L-arginine and locally blocks T cell proliferation. Therefore, the characteristic energy metabolism of tumor cells leads to immune suppression and contributes to immune escape processes at the tumor site [1]. Excess dietary Tryptophan has shown to cause increased tumor incidence in tumorous strains of Drosophila [2]. Canton (wild type) flies were exposed to 10mM, 20mM, 30mM, 40mM and 50mM concentrations of Tryptophan. Phenotypic analysis of the exposed flies and qualitative analysis of the isolated DNA was done 24 hours and 48 hours after exposure to Tryptophan. The quality of the DNA was evaluated using Nanodrop and the DNA was subjected to Fragmentation assay to study the damage induced. Phenotypic changes observed were elongated abdomen with distinct curling and discoloration of thorax to mild orange. The isolated DNA was found to be of good quality and the fragmentation assay showed patterns of shearing. As the damage observed was not significant and the tumor induction was not observed in the experimental concentrations, tryptophan was considered non tumorigenic at the above said concentrations. However, higher concentrations of Tryptophan may induce tumor
Classification Of Fungal Infections And General Applications Of Anti Fungal Agents
Priyanka. K,V. Saritha Rani
Golden Research Thoughts , 2012, DOI: 10.9780/22315063
Abstract: Fungal infections are common in human beings and animals. The recent development of novel antifungal agents as significantly contributed to the successful treatment of fungal dieases.Most of these agents are fungistatic and do not kill the fungal cell. Thus facilitating the emergency of resistance species, which further complicate therapy.Alternatively, some of the most effective anti fungal agents are too toxic after continuous use or can only be administered intravenously. The ideal antifungal drug would be non toxic, fungicidal, and amenable to self administration. Anti fungal agents have wider range of applications.
RED TACTON HUMAN AREA NETWORKING
Priyanka Kakade,Khobragade S V
International Journal of Computer & Electronics Research , 2013,
Abstract: All the user-friendly services require technologies that enable communication between people and objects in close proximity. This paper describes a model of human area networking technology that enables communication by touching, a technology we call Red Tacton. Human area networking technology for communication between mobile terminals and between terminals that are embedded in the environment has become important. When cables are used for communication between terminals, the routing of the cables is clearly inconvenient. When very weak radio signals are used for the communication, data speeds are reduced by packet collision and other such problems in crowded places such as exhibition sites and security risk from unwanted signal interception is another problem. Technology for solving such problems includes the use of the person body as a signal path for communication. A transmission path is formed automatically when a person comes into contact with a device and communication between mobile terminals begins. Here, the human body acts as a transmission medium supporting IEEE 802.3 half duplex communication at 10Mbit/s.

International Journal of Advanced Computer Research , 2012,
Abstract: Human area network(HAN) makes use of human body as a medium for transmission of signal. This is also known as RED TACTON. Because of its unique characters, this technology can be said as a novel and promising technology many applications in the fields such as personal area network (PAN), computer network access, implant biomedical monitoring, human energy transmission, etc. In this paper, work has been carried out for analyzing the electrostatic coupling for the RED TACTON technology by performing computer simulation using the developed finite-element models, in which (1) we have the incidence and reflection of electronic signal in the upper arm model which were analyzed by using the theory of electromagnetic wave, (2) the finite-element models of electrostatic coupling were developed by using the electromagnetic analysis package of ANSYS software, (3) the signal attenuation of electrostatic coupling were simulated under the conditions of different signal frequency, electrodes direction, electrodes size & transmission distance. Finally, important conclusions are deduced on the basis of simulation results.

Abstract:

In the present study, a novel non radioactive digoxigenen labelled PCR-DNA probe was developed targeting nor-1 gene to assess the contamination of aflatoxigenic Aspergillus species in food grain samples from Southern parts of India. The sensitivity of developed PCR-DNA probe was determined to be 10 pg of genomic DNA and 1 pg of purified PCR product. The specificity of the DNA probe was validated by testing against an array of Aspergillus, Fusarium and Penicillium spp. A total of 89 Aspergillus isolates were recovered from 152 grain samples of maize, paddy, and groundnut. Among them, maize had the highest (90%) incidence of toxigenic Aspergillus species. When developed PCR-DNA probe was evaluated onto pure cultures of toxigenic and nontoxigenic Aspergillus species, 60 samples were positive for the nor-1 gene probe. DNA probe results unequivocally matched with the HPLC analysis. In conclusion, the novel PCR-DNA probe developed in this study may find its application in rapid detection of aflatoxin-producing Aspergillus isolates from contaminated cereal grains.

International Journal of Engineering Science and Technology , 2011,
Abstract: In order to conserve energy, the use of azeotropes in a multistage refrigerating system is quite timely. Depending upon the requirement, such a system incorporates conventionally either a water cooled or air cooled condenser. The total operating cost of a refrigerating system with a water cooled condenser comprises the cost of water and the cost of electricity needed to drive the compressor(s). There is enough potential for research in finding out the ways to achieve maximum coefficient of performance and the least operating costsimultaneously for multi-stage azeotropic system. However, to avoid overloading of sewage facilities and to comply with municipal codes for the use of water, the water flow rate required in refrigerating system should be minimized. In the present investigation, economic water rates for two stage refrigerating systems, operating on mostcommonly used azeotropes R-500 and R-502, have been searched out over a wide range of operating limits. Such economic rates, if followed, would produce maximum COP and consume minimum power. The effects ofcontrolling variables, e.g. approach, cost ratio etc have also been studied on the heat transfer to condenser, optimum condensing temperature and economic water rate. The results have been presented in tabular form only However the work on graphical presentation is in progress and is within the scope of future research work.
