Pericentric inversion of chromosome 9[inv(9)(p12q13)]: Its association with genetic diseases
Rao Babu,Kerketta Lily,Korgaonkar Seema,Ghosh Kanjaksha
Indian Journal of Human Genetics , 2006,
Abstract: Background: The chromosomal polymorphism of short arms of acrocentric chromosomes and heterochromatin variation of Chromosomes 1, 9, 16 and Y have been reported in humans. The pericentric inversion of Chromosome 9 is commonly seen in normal humans and the frequency estimated to be 1 to 3% in general population and inherited in mendalian fashion or might occur spontaneously without any clinical significance. Aim: The aim of the study was to study the frequency of inv(9) and its clinical correlation with human genetic diseases. Materials and Methods:0 The chromosomal analysis using GTG-banding was carried out in 3,392 cases suspected with genetic diseases. Results: The pericentric inversion frequency of different chromosomes in our study was 1.24% and frequency of inv(9)(p12q13) was high (64.29%) compared to other pericentric inversions in our study. A high frequency (9.33%) of inv(9)(p12q13) was detected in children with dysmorphic features and congenital anomalies. Conclusion: As a high frequency of inv(9)(p12q13) detected in children with dysmorphic features, the inv(9) definitely have a role in the abnormal phenotype development. During inversion event there might be loss or suppression of euchromatin chromosome region and hence detailed chromosomal break point study is important to understand the clinical significance of the pericentric inversion of Chromosome 9.

Indian Journal of Human Genetics , 2007,
Abstract: We describe a five-year-old proband presented with Dandy-Walker malformations, right microopthalmia, hamstring contractures, undescended testis with absence of testis in right scrotum in addition to typical trisomy 9p clinical features. Routine cytogenetic studies with GTG - banding showed 46,XY,der(12)t(9;12) (p12;q13.3),mat karyotype (trisomy 9p). Chromosomal analysis of the father was normal and phenotypically normal mother had 46,XX,t(9;12)(p12;q13) karyotype. Fluorescence in situ hybridization analysis with single copy probes bA5OIA2 (9p11.2), bA562M8 (12p12.1) and centromere probes (9) showed break point at 9p12.1 region. The gene dosage effect of Chromosome 9p along with environmental factors might be associated with Dandy- Walker malformations in the patient.
Thread Synchronization: From Mutual Exclusion to Transactional Memory
Kamakoti V,Korgaonkar Kunal
IETE Technical Review , 2011,
Abstract: Transactional memory (TM) is being viewed by researchers as a suitable mechanism to perform shared-memory synchronization on upcoming many-core systems. This paper provides an introductory material on TM, followed by a background of important historical work on synchronization leading to current TM research. The paper reviews recent pure hardware and hardware-software TM design proposals, and finally brings out a list of interesting open problems in this field.

Seema Sharma
Open Journal of Social Sciences (JSS) , 2014, DOI: 10.4236/jss.2014.28021
Abstract: The study aimed at finding out the relationship between environmental awareness and emotional intelligence of student teachers and teachers. The sample of the study consisted of 200 student teachers (100 male and 100 female) and also of 100 teachers (50 male and 50 female). The sample was taken from 15 self-financed B.Ed. colleges of Ghaziabad District of CCS University, Meerut (UP). Environmental awareness measure scale by Dr. P. K. Jha and emotional intelligence inventory by Dr. S. K. Mangal and Mrs. Shubhra Mangal was used for assessing the environmental awareness and emotional intelligence of student teachers and teachers. Data was analyzed by using mean, SD, t-test and by Pearson Product Moment Correlation Technique. The results showed that there was no significant difference between male and female student teachers and teachers regarding environmental awareness and emotional intelligence. The results also showed that the environmental awareness of male and female student teachers was also found to be slightly positively but not significantly correlated with emotional intelligence. The environmental awareness of male teachers was found to be moderately, positively and significantly correlated with emotional intelligence. On the other hand the environmental awareness of female teachers was found to be slightly positively but not significantly correlated with emotional intelligence.
Blocking Response Surface Designs Incorporating Neigh-bour Effects  [PDF]
Eldho Varghese, Seema Jaggi
Open Journal of Statistics (OJS) , 2011, DOI: 10.4236/ojs.2011.13023
Abstract: In this paper, blocking in response surface for fitting first order model incorporating neighbour effects has been investigated. The conditions for orthogonal estimation of the parameters of the model have been obtained. A method of constructing designs which ensures the constancy of variance of the parameter estimates of the model has also been given.
Influence of Sintering Temperature on Densification, Structure and Microstructure of Li and Sb Co-Modified (K,Na)NbO3-Based Ceramics  [PDF]
Rashmi Rani, Seema Sharma
Materials Sciences and Applications (MSA) , 2011, DOI: 10.4236/msa.2011.210191
Abstract: Polycrystalline samples of Lead free (K0.5Na0.5)1-x(Li)x(Sb)x(Nb)1-xO3 ceramics with nominal compositions (x = 0.040 to 0.060) have been prepared by high temperature solid state reaction technique. X-ray diffraction (XRD) pattern shows that the crystal structure transforms from orthorhombic to tetragonal as Li and Sb content increases. Normal sintering process yield compounds with density ~98.2% of the theoretical value. Densification of the Li and Sb co-doped KNN ceramics might be explained by the liquid-phase sintering. This may be attributed to the low melting temperature of Li compounds that appears to promote the formation of a liquid phase during sintering.
Green Synthesis of Silver Nanoparticles Using Extracts of Ananas comosus  [PDF]
Naheed Ahmad, Seema Sharma
Green and Sustainable Chemistry (GSC) , 2012, DOI: 10.4236/gsc.2012.24020
Abstract: The biosynthesis of nanoparticles has been proposed as a cost effective and environmental friendly alternative to chemical and physical methods. Plant mediated synthesis of nanoparticles is a green chemistry approach that intercom nects nanotechnology and plant biotechnology. In the present study, synthesis of silver nanoparticles (AgNPs) or (Green-Silver) has been demonstrated using extracts of Ananas comosus reducing aqueous silver nitrate. The AgNPs were characterized by Ultraviolet-Visible (UV-vis) Spectrometer, Energy Dispersive X-ray Analysis (EDAX), Selected Area Diffraction Pattern (SAED) and High Resolution Transmission Electron Microscopy (HRTEM). TEM micrographs showed spherical particles with an average size of 12 nm. The XRD pattern showed the characteristic Bragg peaks of (111), (200), (220) and (311) facets of the face center cubic (fcc) silver nanoparticles and confirmed that these nanoparticles are crystalline in nature. The different types of antioxidants presented in the pineapple juice synergistically reduce the Ag metal ions, as each antioxidant is unique in terms of its structure and antioxidant function. The re- action process was simple for formation of silver nanoparticles and AgNPs presented in the aqueous medium were quite stable, even up to 4 months of incubation. This work proved the capability of using biomaterial towards the synthesis of silver nanoparticle, by adopting the principles of green chemistry.

Sharad Kandalkar, Seema Samdurkar
International Journal of Astronomy and Astrophysics (IJAA) , 2014, DOI: 10.4236/ijaa.2014.43038

A Bianchi type-V space time is considered with linear equation of state in the scalar tensor theory of gravitation proposed by Brans and Dicke. We use the assumption of constant deceleration parameter and power law relation between scalar field ø and scale factor R to find the solutions. Some physical and kinematical properties of the model are also discussed.

Awatuf Elshirif, Seema Sadiq
Open Journal of Obstetrics and Gynecology (OJOG) , 2014, DOI: 10.4236/ojog.2014.49076

Case: A 52-year-old female who was presented to accident and emergency felt unwell; she reported that she had an IUCD inserted over 20 years ago. On examination she had a large calcified mass occupying the vagina. CT scan confirmed a calcified IUCD. Conclusion: Serious complication secondary to IUCD is rare but well recorded, extensive calcification as in this case is very rare and has not been previously reported.
