Prevalence of asymptomatic bacteriuria and associated risk factors among antenatal women attending a tertiary care hospital
Humera Qudsia Fatima Ansari,Aruna Rajkumari
Journal of Medical and Allied Sciences , 2011,
Abstract: Asymptomatic bacteriuria (ASB) is the commonest bacterial infec-tion which requires medical treatment in pregnancy. Untreated ASB in 25-30% of can cases lead to pyelonephritis which may lead to increased risk of abortions, intrauterine fetal deaths, prematurity and low birth weight. A cross-sectional study was conducted at Gandhi Hospital over a period of ten months with 125 asymptomatic pregnant women in the age group of 15-35 years. The objectives of the study were to determine prevalence of asymptomatic bacteriuria, to identify its risk factors and to compare the screening methods. Of the 125 pregnant women, significant bacteriuria was seen in 21 (16%). The prevalence of bacteriuria showed a rise with increasing maternal age and increasing gestational period. Anemics and hypertensives were at greater risk. The most common isolates were Klebsiella pneumoniae and Staphylococcus aureus (28% each). Culture proved to be the gold standard for diagnosis. Catalase and Nitrate reduction tests were used as screening methods with a sensitivity of 90.48% and 71.43% respectively. Multiple drug resistance was observed in Gram-positive and Gram-negative isolates. Routine screening for asymptomatic bacteriuria is therefore recommended throughout pregnancy to avoid adverse fetal and maternal outcomes.
Role of Ethics Committee and issues involved in Bio-medical research on human beings – an update.
Rajkumari Ajita
Calicut Medical Journal , 2008,
Abstract: With the ever increasing and expanding in medical sciences and bio-medical research involving human beings, the role of Ethics Committee is becoming very important. It is mandatory that all proposals on biomedical research involving human subjects should bescrutinized and cleared by an appropriately constituted Institutional Ethics Committee (IEC) also referred to as Institutional Review Board(IRB) in many countries, to safeguard thewelfare and the rights of the participants. The purpose of a Research Ethics Committee is to protect the dignity, rights, safety and well being of all actual or potential research participantsand also to ensure that the privacy, safety, social sensitivities and welfare of participants are protected. This review paper makes anattempt to educate the medical fraternity about the role of Ethics Committee and share basic principles and contemporary issues of ethics guidelines with the physicians doing research on human beings.
Environmental Impact on Biomass and Allelopathic Effect of Cenchrus ciliaris.L
RAJKUMARI PARWANI,ARCHANA MANKAD
European Academic Research , 2013,
Abstract: The study was conducted at the GEER foundation, Gandhinagar, India to evaluate environmental impact on biomass production of Cenchrus ciliaris.L (buffel grass) and its allelopathic effect on Dichanthium annulatum and Sehima nervosum. These grasses were grown in separate plots and also in combination. Growth parameters which were studied for all sets were Shoot length, Above Ground Biomass (AGB), Below Ground Biomass (BGB) and number of leaves and meteorological data were also recorded. It was observed that C.ciliaris could survive through extreme climate and Dichanthium annulatum and Sehima nervosum could not flourish in the presence of Cenchrus ciliaris, which resulted in the maximum biomass of Cenchrus ciliaris. The effect of different seasons on biomass of Cenchrus ciliaris was observed over a year. Statistical analysis of the data showed significant variation in biomass.
Cryptosporidiosis in a tertiary care hospital in Andhra Pradesh

Indian Journal of Medical Microbiology , 2001,
Abstract: Enteric protozoal parasitic infection has become an important cause of morbidity in children and adults. In the developing countries the association of Cryptosporidium with acute and persistent diarrhoea has been striking. Stool samples from 1002 patients (800 adults and 202 children) suffering from diarrhoea or other gastrointestinal symptoms were examined for the presence of Cryptosporidium parvum oocysts by modified Ziehl Neelsen stained smears. C. parvum was detected in 2.99% of children and 0.12% adults. Other parasites detected were E. histolytica (6.18%), G. lamblia (1.49%), A. lumbricoides (1.49%), hookworm (1.39%), Strongyloides stercoralis (0.39%), and Taenia (0.09%).
Do the Indian Agricultural Commodities’ Prices Exhibit Non-Linear Mean Reversion? An Empirical Evidence  [PDF]
Aviral Kumar Tiwari, Mothkuri Aruna, Aruna Kumar Dash
Theoretical Economics Letters (TEL) , 2015, DOI: 10.4236/tel.2015.52039
Abstract: Indian economy’s inflation index often reflects double digit tendencies due to supply side shortages caused by droughts, rise in the prices of crude oil in the international markets etc. These factors may be responsible for non-linear behaviour of inflation index. Against this backdrop, an attempt is made in this study to capture non-linear mean reversion of prices of 47 agricultural commodities of India. The study employs powerful non-linear unit root test so as to generate robust findings to infer valid policy implications. The results of the study indicate the presence of unit root with drift process for Food Grains, Cereals, Pulses, Fruits, Vegetables, Primary Articles, Ragi and Rice. And for rest of the commodities, it is observed that there is evidence of mean reversion and therefore, the impact would be only temporary in nature. Thus, the empirical inferences enable the policy makers to design appropriate short term and long term polices related to the prices of agricultural commodities.

LLR ENHANCEMENT MODEL FOR A TURBO EQUALIZER
Aruna Tripathy
International Journal of Engineering Sciences and Emerging Technologies , 2012,
Abstract: The turbo equalizer (TEQ) is a baseband signal processor that combines the tasks of channel equalization and channel decoding in a closed loop by using turbo principles. The basic objective of a TEQ is to take care of interference in a communication system arising due to a host of reasons and correct the random errors caused by additive white Gaussian noise (AWGN) simultaneously. All the TEQs reported in literature can be broadly categorized into three types; the trellis based equalizers, the apriori aided minimum mean square error (MMSE) filters and the soft interference canceller (SIC) type of filters. Pivotal to the operation of all the TEQs is the flow of the extrinsic information between the equalizer and the channel decoder. The extrinsic information is the information about a given bit available by the use of knowledge about other bits in a transmitted data stream. Most often, the extrinsic information is modeled as a Gaussian random variable. However, a generic mathematical model capturing the operations of a TEQ seems to be missing in literature. It is with this motivation that we propose a suitable mathematical model for a TEQ under converging conditions. This is the log likelihood ratio (LLR) enhancement model that describes the evolution of the extrinsic information as observed at the equalizer output. The LLR becomes a monotonically increasing function of the signal to noise ratio (SNR) from the no apriori condition to the perfect apriori condition about the transmitted bits. KEYWORDS:
A Report on the Mock Interviews Conducted for Students of MCA IV Semester in April 2011 at the ELTC

Abstract: A mock interview was conducted for students of MCA IV Semester, University of Hyderabad on 9, 10 Apr-2011 with the help of the management and experts from outside. The Interview panel assessed the technical and communication competence of the students and gave them individual and group feedback on their performances. Students found it to be a good rehearsal for actual job interview. it was treated as a part of placement related training and continuous assessment of the students during the course.
