Sailabala Garikaparthi,Renuka Inuganti Venkata,Krishna Bharathi Yarlagadda,Annapurna Parvatala
Case Reports in Oncological Medicine , 2012, DOI: 10.1155/2012/213765
Abstract: Sarcoma-like mural nodules occur predominantly in middle-aged women. Distinction of these lesions from true sarcomatous nodules and foci of anaplastic carcinoma is important because of the worse prognosis of these tumors in comparison with the favorable behavior of sarcoma-like mural nodules. In this report we describe the case of a 35-year-old woman with a mucinous ovarian tumor having a mural nodule in the wall.
Benign Mucinous Tumor of Ovary with a Sarcoma-Like Mural Nodule: A Case Report

Abstract: Sarcoma-like mural nodules occur predominantly in middle-aged women. Distinction of these lesions from true sarcomatous nodules and foci of anaplastic carcinoma is important because of the worse prognosis of these tumors in comparison with the favorable behavior of sarcoma-like mural nodules. In this report we describe the case of a 35-year-old woman with a mucinous ovarian tumor having a mural nodule in the wall. 1. Introduction Mucinous cystic tumors of ovary whether benign or malignant may be associated with sarcoma-like mural nodules (SLMNs). These nodules resemble a gingival epulis or giant cell tumor of bone and are reactive rather than neoplastic. Their distinction from true sarcomatous mural nodules and foci of anaplastic carcinoma is extremely important since each of these lesions carries a different prognosis [1]. We describe a benign ovarian mucinous tumor with SLMN. The value of immunohistochemistry (IHC) in the differential diagnosis of these lesions is discussed. 2. Case Details A 35-year-old female patient presented with lower abdominal pain for six months. On examination a swelling of 15 to 18?cms was detected. Ultrasonography revealed a right ovarian mass, and ovarian cystectomy was performed. Grossly the ovarian cyst measured with an attached tube of 3?cms. The outer surface was whitish and smooth, with an elevation of 2?cms diameter (Figure 1). On cut section the cyst was unilocular with mucinous material and a gray-brown nodule. Microscopic examination showed features of a mucinous cystadenoma, surface epithelium being papillary and lined by tall columnar mucinous epithelium. Sections from the gray-brown nodule showed increased cellularity in the stroma with spindle- and polygonal-shaped cells, and plenty of osteoclastic type of giant cells (Figure 2). The stromal cells were monomorphic with no nuclear atypia, and minimal mitotic activity (1–5/10HPF) was seen. The giant cells were similar to osteoclastic giant cells of bone (Figure 3). Immunohistochemistry for Vimentin was positive, and pancytokeratin was only focally positive. Figure 1: Ovarian tumor with mural nodule. Figure 2: Microphotograph showing cyst lining and cellular mural nodule inset: SLMN with spindle-shaped stromal cells and giant cells (H and E ×100). Figure 3: Osteoclastic type of giant cells and cellular stroma (H and E ×400). 3. Discussion Various types of mural nodules are found in the walls of mucinous ovarian tumors. They include anaplastic carcinoma, carcinosarcoma, and sarcoma-like nodules, mixed nodules, and leiomyomas [2]. We describe a benign ovarian tumor
Potential Energy Curves & Material Properties  [PDF]
Devarakonda Annapurna Padmavathi
Materials Sciences and Applications (MSA) , 2011, DOI: 10.4236/msa.2011.22013
Abstract: Potential energy curves govern the properties of materials. A critical analysis of the potential energy curve helps better understand the properties of the material. Potential energy curve and in turn the properties of any material depend on the composition, bonding, crystal structure, their mechanical processing and microstructure. The type, strength, and directionality of atomic bonding controls the structure and material properties viz., melting temperature, thermal expansion, elastic stiffness, electrical properties, ductility and toughness etc. This paper attempts to bring out the correlation between the potential energy curves with the properties of materials.

Taskeen Zaidi, Annapurna Singh, Vipin Saxena
Computational Water, Energy, and Environmental Engineering (CWEEE) , 2013, DOI: 10.4236/cweee.2013.23009
Abstract: Modeling plays an important role for the solution of the complex research problems. When the database became large and complex then it is necessary to create a unified model for getting the desired information in the minimum time and to implement the model in a better way. The present paper deals with the modeling for searching of the desired information from a large database by storing the data inside the three dimensional data cubes. A sample case study is considered as a real data related to the ground water and municipal water supply, which contains the data from the various localities of a city. For the demonstration purpose, a sample size is taken as nine but when it becomes very large for number of localities of different cities then it is necessary to store the data inside data cubes. A well known object-oriented Unified Modeling Language (UML) is used to create Unified class and state models. For verification purpose, sample queries are also performed and corresponding results are depicted.
Impact of Population Structure, Growth Habit and Seedling Ecology on Regeneration of Embelia ribes Burm. f. —Approaches toward a Quasi in Situ Conservation Strategy  [PDF]
Dhavala Annapurna, Ashutosh Srivastava, Trilok Singh Rathore
American Journal of Plant Sciences (AJPS) , 2013, DOI: 10.4236/ajps.2013.46A005
Abstract:

Embelia ribes Burm f., also known as Vidanga or Baibidanga, belonging to the family of Myrsinaceae, is an important but vulnerable medicinal woody climber. Recent survey and observations of E. ribes in different aspects like distribution, population structure, growth habit, climate, natural regeneration and seedling ecology in Karnataka have been thoroughly discussed. This is the first report on artificial regeneration through seeds of diverse origins in ex-situ and in situ conditions and field planting of them in its natural environment. Field planting of in vitro and nursery raised seedlings showed better field performance in terms of survival and growth in its natural growing areas only. Current studies and observations have shown that this species has low ecological gradient and is a “habitat specialist”. E. ribes being a threatened species with small populations coupled with low ecological gradient and virtually no natural regeneration, a modified approach of quasi in situ conservation where in in-situ raising of seedlings of diverse origin with an aim to enrich the diversity of existing population was attempted with considerable success.

Optimization of 1, 3-Propanediol production by Klebsiella pneumoniae 141B using Taguchi methodology: Improvement in production by cofermentation studies
Vanajakshi Jalasutram,Annapurna Jetty
Research in Biotechnology , 2011,
Abstract: In this study, 1,3-Propanediol production by isolated Klebsiella pneumoniae 141Bstrain using glycerol as a substrate has been investigated. Initial experiments were carried forthe screening of nitrogen sources and yeast extract was found to be the optimum source. Theimpact of vitamin B12 on 1,3-PDO production was evaluated by growing the strain invitamin B12 supplemented medium. One interesting phenomenon noticed that 1,3-PDOproduction was not increased by vitamin B12 supplementation, which aided in lowering thecost of fermentation process. Further optimization studies were carried out with six selectedfermentation parameters such as pH, yeast extract, glycerol, calcium carbonate, inoculum sizeand temperature at three different levels. 1,3-PDO production has improved to 67% inTaguchi statistical optimization method. To further increase the 1,3-PDO production,cofermentation studies were carried out with the optimized medium having glucose andsucrose as co substrates. There was a sharp increase in the 1,3-PDO yield from control (0.70mol/mol) having glycerol alone to glycerol-sucrose mixture (0.98 mol/mol) followed byglycerol-glucose mixture (0.84 mol/mol). The sucrose-glycerol mixture with vitamin B12-freemedium allows the development of an economical biological process for the production of1,3-PDO from renewable resources.
Contrastive Study of “Time” in Iranian-Indian Mythology
BIBIAGHDAS ASGHARI,ANNAPURNA M.
Antrocom : Online Journal of Anthropology , 2011,
Abstract: The main aim in the study is to compare and contrast the textual contents and the formal structures that are involved in the myth of ‘time’ in Indian and Iranian mythologies. Three questions will be replay: What are the divisions of time? What is the function of time in the mythical system in both myths of Iran and India? And what is the formal structure in this myth in the both mythologies? Data collection for this article has been done with a documentary approach. The Primary sources involved the Avesta and the RigVeda and secondary sources (include: 31 books, related article) were reviewed, after data gathered from those, the data analysis has been done in this study.Comparison of two myths is done with following mythical three indices: 1. Structure (trinity) 2.Binary Oppositions 3.Archetypal patterns time. In the Iranian myth, like the Hindu myth time is divided into three and then again four part horizontally. In Hindu myths, time is cyclical. Lord Brahma in Hindu mythology is referred to as the creator. The Zoroastrian concept of time is linear not cyclical. In the creation myth Unlimited/limited and Numeric /Divine time are cosmic oppositions; Golden Age / Iron Age indicate sociological opposition.
Optimization of the Voltage Doubler Stages in an RF-DC Convertor Module for Energy Harvesting  [PDF]
Kavuri Kasi Annapurna Devi, Norashidah Md. Din, Chandan Kumar Chakrabarty
Circuits and Systems (CS) , 2012, DOI: 10.4236/cs.2012.33030
Abstract: This paper presents an optimization of the voltage doubler stages in an energy conversion module for Radio Frequency (RF) energy harvesting system at 900 MHz band. The function of the energy conversion module is to convert the (RF) signals into direct-current (DC) voltage at the given frequency band to power the low power devices/circuits. The design is based on the Villard voltage doubler circuit. A 7 stage Schottky diode voltage doubler circuit is designed, modeled, simulated, fabricated and tested in this work. Multisim was used for the modeling and simulation work. Simulation and measurement were carried out for various input power levels at the specified frequency band. For an equivalent incident signal of –40 dBm, the circuit can produce 3mV across a 100 k? load. The results also show that there is a multiplication factor of 22 at 0 dBm and produces DC output voltage of 5.0 V in measurement. This voltage can be used to power low power sensors in sensor networks ultimately in place of batteries.
Radiation-induced hematological alterations and their inhibition by Aegle Marmelos fruit extract
Agrawal Annapurna,Goyal Pradeep K.
Nuclear Technology and Radiation Protection , 2011, DOI: 10.2298/ntrp1103237a
Abstract: This study was carried out to observe the radio protective potential of Aegle Marmelos fruit extract (AME) against radiation-induced hematological and biochemical alterations in blood and liver of mice. For this purpose, adult Swiss albino mice were exposed to 6 Gy gamma radiation in the presence (experimental) or absence (control) of the extract (100 mg/kg body weight animal/day). Exposure to radiation resulted in a significant decline in the count of erythrocyte, hemoglobin (Hb) and hematocrit (Hct) in peripheral blood. In contrast, extract-pretreated irradiated animals had a significant rise in all of these blood constituents, as compared with the irradiated control. Furthermore, a significant elevation in lipid peroxidation over normal was recorded in the irradiated control, whereas such increase was considerably lesser in extract-pretreated animals. Likewise, pretreatment with AME caused a significant increase in glutathione levels in the serum, as well as in the liver, in comparison to irradiated controls. These results indicate that AME may be responsible for the protection of stem cells in bone marrow, subsequently resulting in a rise of hematological constituents in peripheral blood. The present study affirms the prophylactic use of AME against radiation-induced hematological and biochemical alterations in mammals.
Automation of J2EE Product Certification Process
Iddalgave Sandeep,Annapurna P. Patil
International Journal of Computer Science Issues , 2012,
Abstract: Automation is a process of developing a tool or a product to perform on its own, in order to achieve all the functionalities required of a complex system, without human intervention. The current Certification Process of the J2EE product in IBM is consuming unnecessary time even for the valid products. In order to reduce this processing overhead, the process of automation was proposed by the technologist to save time so as to accomplish the task early. The need for automating the tool of Certification arose due to unwanted utilization of man-hour and man-power. The existing system halts after the tool finishes the comparison of the listings (which contain details of the build, its environment and the list of files present within the build), until the administrator logs-in. Administrator checks each transaction ID individually for intimating the clients about the status of their products. The proposed system aims at sending the intimation to the clients as soon as the comparison is done successfully, without the intervention of administrator i.e., an automated notification will be sent after successful comparison of the listings. The tool will also provide an option to generate chart/graph whenever the managerial team needs it at just one click. The work carried out here is aimed at automating the process of certifying the Java products or assets developed by IBM Software Product Groups. It also aims at generating graphs at real-time for the number of products certified till date. The certification process is for IBM JRE/SDK used by IBM Software Product Groups. It will be done by comparing the listings submitted by the IBM Software Product Groups and the reference listings present in the Certification server. JRE/SDK should adhere to the constraints as per the Oracle license.
