Prevalence of Lingual eruption of mandibular permanent incisors and relationship between lingual eruption and arch– form in 6-8 years old Children in kerman
R Shojaeipour,Sh Arya
Journal of Isfahan Dental School , 2009,
Abstract: Introduction: The eruption of mandibular permanent incisors lingual to retained primary incisorsis often a source of concern for parents. It is seen both in patients with an obvious arch lengthinadequacy and in those with a desirable amount of spacing of the primary incisors. Because nostatistics on prevalence of lingual eruption of mandibular permanent incisors exists, the aim of thepresent study was to investigate the prevalence of lingual eruption of mandibular permanentincisors and relationship between lingual eruption an arch- form in 6-8 years old children inkerman during autumn 2006.Material and Methods: In this descriptive-cross sectional study, 4278 students (%50 girl, 50%boy) were selected randomly form 50 Schools in Kerman. Data including age, sex, position oflingual eruption of mandibular permanent incisors and dental arch form were recorded and thenanalyzed using t and chi- square tests.Results: The prevalence of Lingual eruption of mandibular permanent incisors was 2.2%. Lingualeruption of mandibular permanent incisors in girls was significantly more than boys (p value
Spin-Isospin Structure and Pion Condensation in Nucleon Matter
Arya Akmal,Vijay R. Pandharipande
Physics , 1997, DOI: 10.1103/PhysRevC.56.2261
Abstract: We report variational calculations of symmetric nuclear matter and pure neutron matter, using the new Argonne v18 two-nucleon and Urbana IX three-nucleon interactions. At the equilibrium density of 0.16 fm^-3 the two-nucleon densities in symmetric nuclear matter are found to exhibit a short-range spin-isospin structure similar to that found in light nuclei. We also find that both symmetric nuclear matter and pure neutron matter undergo transitions to phases with pion condensation at densities of 0.32 fm^-3 and 0.2 fm^-3, respectively. Neither transtion occurs with the Urbana v14 two-nucleon interaction, while only the transition in neutron matter occurs with the Argonne v14 two-nucleon interaction. The three-nucleon interaction is required for the transition to occur in symmetric nuclear matter, whereas the the transition in pure neutron matter occurs even in its absence. The behavior of the isovector spin-longitudinal response and the pion excess in the vicinity of the transition, and the model dependence of the transition are discussed.
Cutaneous tuberculosis in children a clinico-microbiological study
Arya Latika,Koranne R,Deb Manorama
Indian Journal of Dermatology, Venereology and Leprology , 1999,
Abstract: Twenty untreated patients of cutaneous tuberculosis varying from 2-12 years of age were included in the study. The incidence of cutaneous tuberculosis amongst the paediatric dermatological patients was 0.36%. Of these, 10 had lupus vulgaris, 8 had scrofuloderma, 3 had tuberculosis verrucosa cutis and 2 had lichen scrofulosorum. Three patients concomitantly had more than one type of skin tuberculosis. Systemic involvement in the form of pulmonary and osseous system was seen in 45% cases. The tuberculin test was uniformly positive. Affirmative clinico-histopathological correlation was observed in all the patients. However, acid fast bacilli could not be demonstrated in any of the sections. Only one patient (scrofuloderma) exhibited AFB on smear examination. In the same patient, M. tuberculosis could be cultured on L-J medium. However, Elisa for IgM antibodies in serum was positive in 12 (60%) cases. Need for newer techniques in the diagnosis is emphasised.
Unusual retinal manifestation in a combination of Sturge-Weber and Klipplel-Trenaunay syndrome-A case report
Sharma Pradeep,Arya A,Azad R
Indian Journal of Ophthalmology , 1990,
Abstract: An unusual retinal manifestation of arteriovenous communications is reported in a case showing a combination of Sturge-Weber and Kippel-Trenaunay syndromes. The arteriovenous communications are thought to be similar to those seen in the limbs in Parkes-Weber syndrome. This retinal finding indicates that the three syndromes are intricately related to each other and may be an incomplete manifestation of a single pathophysiologic entity which may be named neurocutaneous angiomatosis.

Abstract: A study conducted on forty four triple cross-bred ( Kankrej X Jersey X Holstein Friesian) pregnant heifers (20)and cows (24) on days 90,150, 210 and 275 of gestation for hematological parameters like hemoglobin, red blood cell count and pack cell volume revealed that the values decreased significantly(P<0.01) during advanced pregnancy while MCV, MCH and MCHC did not show any significant difference during the different stages of gestation.
Treatment of 78 type II and type IIIa open fractures by primary closure on suction drain: a prospective study
R. Siwach,R. Singh,S. Arya,R. Gupta
Journal of Orthopaedics and Traumatology , 2007, DOI: 10.1007/s10195-007-0085-9
Abstract: The purpose of this study was to assess if primary closure of wounds on a suction drain can be performed in open fractures after debridement and to determine the risk of infection and nonunion. A total of 78 type II and type IIIa open fractures were managed with primary closure on a suction drain. They were followed until union. Rates of infection, delayed union and nonunion were determined and compared with rates reported in the literature. Overall, 16 fractures (20.5%) were complicated with superficial infections and 8 fractures (10.2%) had deep infections. Delayed union was observed in 11 fractures (14.1%) and nonunion in 12 fractures (15.3%). Primary closure of a wound on a suction drain seems to cause no significant increase in rates of infection, nonunion or delayed union.
Parametric Investigation of Powder Mixed Electrical Discharge Machining of Al-Sic Metal Matrix Composites
R. K. Arya,A. Dvivedi,D. B. Karunakar
International Journal of Engineering Innovations and Research , 2012,
Abstract: – In recent few years composite materials have gained pace in engineering application. But they have poor machinability by using conventional machining methods. So it is required to study about these materials for better use in engineering application. To fulfillment of this aim, a study is done by conduct experiments (i.e. Machining) on Al/SiC metal matrix composite (MMC). From the non-conventional machining process, Powder Mixed Electrical discharge machining (PMEDM) is used to machining of Al/SiC MMC. PMEDM is a technological improvement in conventional EDM, which was previously studied by many researchers to better MRR with good surface roughness (SR). In this study, the controllable machining process parameters (i.e. Peak Current (Ip), Duty Cycle, Powder Concentration (PC), Gap Control and Sensitivity) of PMEDM was selected to experimental investigation. The process performance is measured in terms of material removal rate (MRR) and surface finish (SR). The research outcome will identify the important parameters and their effect on MRR of Al/SiC MMC in the presence of suspended graphite (Gr) powder in a kerosene dielectric of EDM. Response surface methodology (RSM) has been used to plan and analyze the experimental results. The experimental results emerged that only sensitivity has non-significant effect on MMR and SR from the selected process parameters, but it gives significant effects with other factors in interaction. Further it found that, the MRR is directly proportional to Ip and inversely proportional to the PC and duty cycle, and the SR improves at lower Ip and optimum range of PC, gap control and duty cycle.

Abstract: Prime object of present study was to develop and evaluate mucoadhesive tablets of Salbutamol Sulphate by non aqueous granulation of polymers HPMC K-4M (Hydroxypropyl Methyl Cellulose) and Chitosan in different ratios (1:1. 1:2 & 2:1). The tablets were evaluated for weight variation, hardness, thickness, drug content uniformity, mucoadhesion and swelling index. Swelling index of batches containing more HPMC K-4M was greater than that of containing less HPMC K-4M. In vitro bioadhesive strength studies showed that tablets containing more HPMC K-4M were excellent in bioadhesive nature. The in-vitro drug release was studied in phosphate buffer (pH 6.8). And all batches were subjected to release kinetics model fitting.
