Iswar Man Amatya,Bhagwan Ratna Kansakar,Vinod Tare,Liv Fiksdal
Journal of the Institute of Engineering , 2009, DOI: 10.3126/jie.v7i1.2070
Abstract: Nitrate removal in groundwater was carried out by biological method of denitrification process. The denitrification and without denitrification were performed in two different sets of reactors. Each reactor consists of two columns connected in series packed with over burnt bricks as media. The filtration rate varied from 5.3 to 52.6 m/day for denitrification process. The ammonia, nitrate and nitrite nitrogen concentrations were measured at inlet, intermediate ports and outlet. The temperature varied from 10 to 30°C at 2°C intervals. The results demonstrated that high amount of nitrate nitrogen removed in groundwater at denitrification process. The nitrate nitrogen removed by denitrification varied from 3.50 to 39.08 gm/m3/h at influent concentration from 6.32 to 111.04 gm/m3/h. Denitrification was found more significant above 16°C.

Iswar Man Amatya,Bhagwan Ratna Kansakar,Vinod Tare,Liv Fiksdal
Journal of the Institute of Engineering , 2011, DOI: 10.3126/jie.v8i1-2.5102
Abstract: It is important to determine the effect of changing environmental conditions on the microbial kinetics for design and modeling of biological treatment processes. In this research, the kinetics of ammonia oxidation by nitrifying process bacteria under varying pH and temperature conditions are studied. Ammonia oxidation in groundwater was carried out by biological method of nitrification process. The nitrification was performed in one set of reactors. The reactor consists of two columns connected in series packed with over burnt bricks as media. The filtration rate varied from 10.5 to 210.4 m/day for nitrification process respectively. The ammonia, nitrate and nitrite nitrogen concentrations were measured at inlet, intermediate ports and outlet. The temperature varied from 10 to 30°C at 2°C intervals. The results demonstrated that high amounts of ammonia nitrogen nitrified in groundwater at nitrification process. The average ammonia nitrogen oxidation efficiency of 77.27% was achieved from pH 7.3 to 8.0 in the reactor packed with OBB media at 20°C, for the flow rate 500ml/min due to biological nitrification. The total amount of ammonia nitrogen removed by nitrification varied from 0.76 to 17.80 gm/m 3 /h at influent concentration from 2.84 to 149.28 gm/m 3 /h.

Golden Research Thoughts , 2012, DOI: 10.9780/22315063
Abstract: E-Commerce is buying and selling goods and products over internet. E -commerce includes not only buying and selling goods over Internet, but also various business processes within individual organizations that support the goal. As with ecommerce, e-business (electronic business) also has a number of different definitions and is used in a number of different contexts. Specifically, the use of ICTin business has enhanced productivity, encouraged greater customer participation, and enabled mass customization, besides reducing costs. One of the first to use the term was IBM, in October 1997, when it launched a campaign built around e-business.

Post-mastectomy breast reconstruction: Microsurgical methods
Ramakrishnan Venkat,Tare Makarand
Indian Journal of Plastic Surgery , 2007,
Abstract: Post-mastectomy breast reconstruction has become the standard of care in the western world. Breast reconstruction using autologous tissue can be performed in a safe, reliable and predictable fashion. The ultimate goal is to reconstruct a symmetrical autologous tissue mound comparable in shape, size and volume to the opposite breast without compromising the oncology clearance. Abdominal tissue remains the first choice for breast reconstruction though other alternatives are rapidly evolving.
Review of Research , 2012,
Abstract: The effect of foreign direct investment on the domestic economy has been widely debated in literature, but a consensus opinion has not emerged. Critics have attributed the Asian banking crisis to the growth of foreign direct investment following the liberalization of foreign investment restrictions. Generally, the argument runs that foreign investors create a destabilizing influence on stock prices. Stiglitz (1998) posits that unregulated capital flows render developing economies more vulnerable to fluctuations in supply of international capital. According to Dornbusch and Park (1995), foreign investors tend to follow positive feedback strategies which cause markets to overreact to fundamental changes in value. Radelet and Sachs (1998) attribute the Asian financial crisis to financial panic. Hamann (1999) concludes that currency crises lead to financial crises:

Indian Streams Research Journal , 2012,
Abstract: U.S. food prices rose 4% in 2007 and are expected to gain 3.5% to 4.5% in 2008. Higher farm commodity prices and energy costs are the leading factors behind higher food prices. Farm commodity prices have surged because(1) demand for corn for ethanol is competing with food and feed for acreage; (2) global food grain and oilseed supplies are low due to poor harvests; (3) the weak dollar has increased U.S. exports; (4) rising incomes in large, rapidly emerging economies have changed eating habits; and (5) input costs have increased. Higher energy costs increase transportation, processing, and retail costs.
Distinct and Contrasting Transcription Initiation Patterns at Mycobacterium tuberculosis Promoters
Priyanka Tare, Arnab China, Valakunja Nagaraja
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0043900
Abstract: Although sequencing of Mycobacterium tuberculosis genome lead to better understanding of transcription units and gene functions, interactions occurring during transcription initiation between RNA polymerase and promoters is yet to be elucidated. Different stages of transcription initiation include promoter specific binding of RNAP, isomerization, abortive initiation and promoter clearance. We have now analyzed these events with four promoters of M. tuberculosis viz. PgyrB1, PgyrR, PrrnPCL1 and PmetU. The promoters differed from each other in their rates of open complex formation, decay, promoter clearance and abortive transcription. The equilibrium binding and kinetic studies of various steps revealed distinct rate limiting events for each of the promoter, which also differed markedly in their characteristics from the respective promoters of Mycobacterium smegmatis. Surprisingly, the transcription at gyr promoter was enhanced in the presence of initiating nucleotides and decreased in the presence of alarmone, pppGpp, a pattern typically seen with rRNA promoters studied so far. The gyr promoter of M. smegmatis, on the other hand, was not subjected to pppGpp mediated regulation. The marked differences in the transcription initiation pathway seen with rrn and gyr promoters of M. smegmatis and M. tuberculosis suggest that such species specific differences in the regulation of expression of the crucial housekeeping genes could be one of the key determinants contributing to the differences in growth rate and lifestyle of the two organisms. Moreover, the distinct rate limiting steps during transcription initiation of each one of the promoters studied point at variations in their intracellular regulation.
Dynamics of Particle in a Box in Time Varying Potential Due to Chirped Laser Pulse  [PDF]
Brijender Dahiya, Vinod Prasad
Journal of Modern Physics (JMP) , 2010, DOI: 10.4236/jmp.2010.16053
Abstract: We describe a computational method for simulating the time dependent quantum mechanical system inter-acting with external field. In this method the Schrödinger equation is solved by expanding the wave function in the basis set of unperturbed Hamiltonian. The expansion yields a set of coupled first order differential equation. For expansion coefficients, the coupled channel method is applied to a particle in a box interacting with external field in the form of chirped laser pulse. The pulse shape is taken as Gaussian. We study the ef-fect of different pulse parameters i.e. chirp rate, intensity, center frequency, box length and laser duration on the dynamics of the particle. Many interesting results are obtained and explained.
Newborn Sex Selection and India’s Overpopulation Problem  [PDF]
Hrishikesh D. Vinod
Modern Economy (ME) , 2013, DOI: 10.4236/me.2013.42013

We begin by noting how India is highly overpopulated and that this creates negative externalities for world environment. Next, we note that females in child-bearing ages alone determine the birth rate, compounding the population growth anywhere. Third, forcing families to have unwanted daughters can increase discrimination against women. Fourth, most countries impose no restrictions on women choosing the sex of their next baby. We use these propositions to argue that cultural preference against daughters in India has important benefits until India achieves net reproduction rate of unity. We argue that the correct policy for malnourished overpopulated India must be the exact opposite of the focus in North America and Europe, where they have an obesity epidemic and declining populations.
