Sinonasal Undifferentiated Carcinoma—A Case Report  [PDF]
C. Aparna, I. V. Renuka
International Journal of Otolaryngology and Head & Neck Surgery (IJOHNS) , 2014, DOI: 10.4236/ijohns.2014.36068
Abstract: Sinonasal tumors with neuroendocrine differentiation are uncommon. They arise from schneiderian epithelium. The authors reported a case in a fifty-six years old female patient who came with complaints of headache and epistaxis. Differential diagnosis and review of literature are presented in detail. This case is presented in view of its rarity.
Primary Amyloid Goitre  [PDF]
C. Aparna, I. V. Renuka, G. Saila Bala, M. Vijayasri
International Journal of Otolaryngology and Head & Neck Surgery (IJOHNS) , 2014, DOI: 10.4236/ijohns.2014.31007

Goitre is defined as the presence of amyloid within the thyroid gland in such quantities as to produce a clinically apparent enlargement. We report a case on a fifty-two-year-old female patient who presented with a rapidly growing thyroid swelling. Thyroid function tests were normal. This case was diagnosed as amyloid goitre and was discussed in detail along with review of literature.

Solvent system designing for “kutaj dadim kwath” using sequential simplex method
Renuka,Dr. V. J. Shukla
International Journal of Pharmaceutical and Biological Research , 2012,
Abstract: A simplex[1] is a geometric figure defined by a number of points equal to one more than the number of factors. If simplex is carried out using two factors then it would give a triangle and three factors are used then resultant will be a tetrahedron. for the present formulation, two factors are used so the resultant was a triangle.This method is clearly based upon the acceptance and rejection criteria in which the point showing best response is accepted and the point showing worst response is rejected. The triangle is flipped at the point of acceptance such that a new triangle is formed which would be the mirror image of the previous one. Likewise the method isrepeated until the best results are obtained.The present study was aimed to design solvent system for the kwath formulation since it is one of the formulation being used in routine practice,so its important to develop chromatographic proifle for the identification and presence of various important constituent that are responsiblefor its efficacy.syneder[2] classification for solvents was used for selection of solvents.
Synthesis of C-8 alkyl xanthines by pentaamminecobalt(III) complex  [PDF]
Renuka Suravajhala
Advances in Biological Chemistry (ABC) , 2013, DOI: 10.4236/abc.2013.36058

Alkyl xanthines underwent selective homolytic aromatic substitution at C-8 position with alkyl groups of pentaamminecobalt(III) complex. In this process of synthesis, we used monoalkyl hydrazines as the radical source in aqueous ammonia solution. Evidence supporting coordination of the alkyl hydrazine to pentaamminecobalt(III) complex by radical trapping was in good agreement with literature. The products were characterized using GC-MS and 1H, 14N and 59Co NMR spectroscopy.


Precise Modelling of a Gantry Crane System Including Friction, 3D Angular Swing and Hoisting Cable Flexibility
Renuka V. S.,Abraham T Mathew
International Journal on Theoretical and Applied Research in Mechanical Engineering , 2013,
Abstract: A crane system offers a typical control problem being an under actuated MIMO system. In this paper the precise modelling of a 2D gantry crane system with 3 DOF is considered. First a simple dynamic model of the system is obtained using Lagrange’s equations of motion. Then, friction non-linearities were added to the model, which were found to decrease the output magnitudes from reference values. The model was further improved by considering the possibility of 3D angular swing which showed more accurate transient responses. Finally, the dynamics of hoisting cable flexibility was added to the system resulting in a complex model requiring time consuming simulation. But, significant change was seen in the angular swing output which will significantly affect controller performance. The models considering either flexibility or 3D load swing are comparatively less complex than the combined model. The precise model to be considered is a trade-off between safety (minimum swing angle) and precise load handling.
A Hybrid Image Cryptosystem Based On OMFLIP Permutation Cipher
G. Sudheer,B. V. S. Renuka Devi
Mathematics , 2012,
Abstract: The protection of confidential image data from unauthorized access is an important area of research in network communication. This paper presents a high-level security encryption scheme for gray scale images. The gray level image is first decomposed into binary images using bit scale decomposition. Each binary image is then compressed by selecting a good scanning path that minimizes the total number of bits needed to encode the bit sequence along the scanning path using two dimensional run encoding. The compressed bit string is then scrambled iteratively using a pseudo-random number generator and finally encrypted using a bit level permutation OMFLIP. The performance is tested, illustrated and discussed.
Dicephalus dipus tribrachius: A case report of unusual conjoined twins
Aparna C,Renuka I,Sailabala G,Nayudamma Y
Indian Journal of Pathology and Microbiology , 2010,
Abstract: A conjoined twin is a rarity. It occurs 1 in 50,000 to 1 in 2,00,000 fetuses. Forty percent of the conjoined twins are stillborn and an additional one-third die within 24 h of birth. They result from late twinning events about 14th day after fertilization. We report a case of stillborn conjoined twins sent for autopsy. The bodies of the fetuses were fused from the thorax to the pelvis. There were two heads, three upper limbs and two lower limbs, with fusion of the thoracic, abdominal and pelvic regions. On systemic examination, some organs were fused and some were separate. A multilocular cyst with milky fluid was seen in the pelvic region. This case is reported in view of its rarity.

Properties of some -dense-in-itself subsets
V. Renuka Devi,D. Sivaraj,T. Tamizh Chelvam
International Journal of Mathematics and Mathematical Sciences , 2004, DOI: 10.1155/s0161171204403391
Abstract: ℐ-open sets were introduced and studied by Janković and Hamlett (1990) to generalize the well-known Banach category theorem. Quasi-ℐ-openness was introduced and studied by Abd El-Monsef et al. (2000). These are ∗-dense-in-itself sets of the ideal spaces. In this note, properties of these sets are further investigated and characterizations of these sets are given. Also, their relation with ℐ-dense sets and ℐ-locally closed sets is discussed. Characterizations of completely codense ideals are given in terms of semi-preopen sets.
A Study Of Infant Feeding Practices And The Underlying Factors In A Rural Area Of Delhi
Taneja D. K,Saha Renuka,Dabas Pratibha,Gautam V. P
Indian Journal of Community Medicine , 2003,
Abstract: Research questions: 1. What are the infant feeding practices in a rural area? 2. What are the reasons underlying the harmful infant feeding practices? Objectives: 1. To study feeding practices among infants. 2. To find out the factors underlying various harmful practices. 3. To find out the sources of information/advice for the prevailing practices. 4. To determine Whether the Practice of giving diluted animal milk to infants is associated with type of family, caste or educational status of mother. Design: Cross-sectional. Setting: Rural field practice center of a Medical College in Delhi. Participants: Mothers of infants 6-9 Months of age, attending immunization clinic. Statistical analysis: Percentage, chi square test. Results: Water was commonly given to breast fed babies and top feeds introduced early. Consequently exclusive breast-feeding was uncommon. Semisolids were started late and diluted animal milk was commonly given to infants; as mothers often thought that child can not digest semisolids or undiluted milk. Milk was also diluted for economic reasons. Insufficient breast milk, illness of mother or child were cited as main reasons for early introduction of top milk.
