Comparison of Alkaline Treatment of Lead Contaminated Wastewater Using Lime and Sodium Hydroxide  [PDF]
Sudhakar M. Rao, G. C. Raju
Journal of Water Resource and Protection (JWARP) , 2010, DOI: 10.4236/jwarp.2010.23032
Abstract: A lead-acid storage battery manufacturing industry in India produces several thousand liters of lead con-taminated acidic wastewater on a daily basis and uses hydrated lime to render the lead-contaminated acidic wastewater alkaline (pH = 8.0). Alkaline treatment of the acidic wastewater with lime though a cost-effective method, generates copious amount of lead-contaminated gypsum sludge. Other alkali agents such as sodium hydroxide, sodium carbonate and dolomite are also used for alkali treatment of the acid wastewaters. The present paper compares the relative efficiency of hydrated lime and 0.05 M to 1 M NaOH solutions with re-spect to 1) amounts of sludge produced, 2) immobilization of the soluble lead in the acidic wastewater (AWW) and 3) increase in TDS (total dissolved solids) levels upon treatment of AWW with NaOH solutions and lime. The study also performs equilibrium speciation upon alkaline treatment of AWW with lime and NaOH (sodium hydroxide) solutions using the Visual MINTEQ program to understand the chemical reac-tions occurring during treatment process.

Advances in Pure Mathematics (APM) , 2011, DOI: 10.4236/apm.2011.15047
Abstract: We establish a common fixed-point theorem for six self maps under the compatible mappings of type (C) with a contractive condition [1], which is independent of earlier contractive conditions.
Resistivity Stability of Ga Doped ZnO Thin Films with Heat Treatment in Air and Oxygen Atmospheres  [PDF]
T. Prasada Rao, M. C. Santhosh Kumar
Journal of Crystallization Process and Technology (JCPT) , 2012, DOI: 10.4236/jcpt.2012.22010
Abstract: The effect of annealing in air and oxygen on structural, electrical and optical properties of gallium doped ZnO thin films was investigated. The X-ray diffraction patterns showed that the films were highly preferentially oriented along (002) plane. After the heat treatment in air and oxygen environments, the intensity of (002) peak was apparently improved. It was found that heat treatment in air atmospheres lead to increase in surface roughness of the film. The GZO films annealed in oxygen at 673 K exhibited low resistivity of 4.21 × 10–3 Ω.cm, while the resistivity of film annealed in air showed a slightly higher value of 7.14 × 10–3 Ω.cm. In addition to this, all films have good optical transmittance about 80% in the visible region. It is found from the photoluminescence studies that the broad visible emissions in GZO films originated from the intrinsic shallow traps (VZn) and deep level vacancies (ZZi, OZn and Vo)
Laparoendoscopic Single Site Donor Nephrectomy: The Preliminary Experience  [PDF]
Santosh A. Olakkengil, M. Mohan Rao
Open Journal of Organ Transplant Surgery (OJOTS) , 2012, DOI: 10.4236/ojots.2012.24013
Abstract: Methods: In our endeavour to give patients visibly scarless surgery we have raised the bar to the next level in laparoscopic donor nephrectomy. We have moved from standard laparoscopy to LESS Laparoendoscopic single site donor nephrectomy. 1997 we introduced laparoscopic donor nephrectomy in Australia. In September 2008 we did our first LESS donor nephrectomy. September 2008 to October 2009, 6 laparoscopic donor nephrectomies were performed using a single port. Two types of devices have been used R-port and SILSTM Port. The device was inserted through an intra umbilical incision using open technique. Surgical technique was similar to the laparoscopic method and standard rigid and roticulator laparoscopic instruments were used. Results: All were completed with no major complications. In 3 an additional 5mm port was added to reduce the dissection time. Average operating time was 4.4 hours, warm ischemia time was an average of 7.16 minutes and post surgery hospital stay was an average of 1.41 days. All grafts functioned immediately after transplantation. Conclusion: Initial experience with this technique is promising. It is too early to draw any conclusions on its benefits to the donor in terms of reduced morbidity. However the donors appreciated the cosmesis. It is yet another learning curve for the transplant surgeon.

Studies on Geochemical and Heavy Mineral Characteristics of Sediments of Gosthani River Estuary  [PDF]
Fatima Rezaye, Shivanna ?, M. Jagannadha Rao
Open Journal of Geology (OJG) , 2018, DOI: 10.4236/ojg.2018.83017
Abstract: The present work deals with the geochemical and heavy mineral characteristics studies of sediments of Gosthani river estuary. The aim of study is to determine the provenance, establish the depositional environment and spatial variability of sediment. From the study it is found that the sediment of Gosthani river contains heavy minerals that consist of Rutile, Garnet, Sillimanite, Staurolite, Monazite, Zercon, Pyroxenes, Epidote, Amphiboles and Opaques minerals. The lesser abundant heavy minerals are amphiboles, zircon, monazite, rutile, staurolite, epidote. These heavy minerals indicate that the sediments were essentially derived from metamorphic provenance varying from medium to high grade and partly from crystalline igneous rocks. Well rounded monazites come from Eastern Ghats. This is based on the occurrence of monazite in pegmatite and charnockites of Eastern Ghats. The various characters of rutile and zircon suggest that each of these minerals has a multisource. According to geochemical studies settling of organic matter is highest in areas where deposition of fine grained sediment takes place. The organic carbon is often a good index for deciphering depositional environment.
Wind Motions around the Tropical Cirrus Using Simultaneous Radar and Lidar Observations over Gadanki (13.45°N, 79.18°E), India  [PDF]

Abstract: The present study describes variation of peak linear depolarization ratio (LDR) with wind around the cloud altitude using simultaneous observation of winds and cirrus cloud for the first time using Indian MST radar and polarization lidar co-located over a low latitude station Gadanki (13.7°N and 79.2°E). Three different cases of passage of the cirrus at different altitudes are noticed, one during a North-East monsoon day and other two during South-West monsoon days. The zonal wind below the cloud height has shown similar variation with LDR during 02 November 2006 and the meridional wind within the cloud height during 25 July 2007 and 08 June 2006 has shown opposite variation with LDR. Even though there is a significant increase in zonal wind due to the existence of tropical easterly jet (TEJ) above cloud height during 25 July 2007 and 08 June 2006, also, the vertical wind is found to be continuously varying during 25 July 2007 and it is upward dominant in the initial stage and is mostly downward in the later stage of observation on 08 June 2006, there is a slight descent in cloud altitude only during 25 July 2007. Thus, the wind above the cloud height alone may not affect the ascent/descent of the cloud top altitude. The potential temperature gradient is high within the cloud heights when the cirrus present near the cold point tropopause indicates the maximum air-mass mixing near the tropopause.
Energy Aware Clustered Based Multipath Routing in Mobile Ad Hoc Networks  [PDF]
Int'l J. of Communications, Network and System Sciences (IJCNS) , 2009, DOI: 10.4236/ijcns.2009.22014
Abstract: With the advance of wireless communication technologies, small-size and high-performance computing and communication devices are increasingly used in daily life. After the success of second generation mobile system, more interest was started in wireless communications. A Mobile Ad hoc Network (MANET) is a wireless network without any fixed infrastructure or centralized control; it contains mobile nodes that are connected dynamically in an arbitrary manner. The Mobile Ad hoc Networks are essentially suitable when infrastructure is not present or difficult or costly to setup or when network setup is to be done quickly within a short period, they are very attractive for tactical communication in the military and rescue missions. They are also expected to play an important role in the civilian for as convention centers, conferences, and elec-tronic classrooms. The clustering is an important research area in mobile ad hoc networks because it im-proves the performance of flexibility and scalability when network size is huge with high mobility. All mo-bile nodes operate on battery power; hence, the power consumption becomes an important issue in Mobile Ad hoc Network. In this article we proposed an Energy Aware Clustered-Based Multipath Routing (EACMR), which forms several clusters, finds energy aware node-disjoint multiple routes from a source to destination and increases the network life time by using optimal routes.
