Allelic Frequency of ABO And Rh D Blood Group Among The Banjara Backward Caste of Yavatmal District, Maharashtra , India

The distribution of ABO blood groups and Rh(D) factor has been studied among the Banjara of Backward population of Yavatmal (Maharashtra). The A, B, O and AB blood group percentage were recorded as 24.54%, 33.82%, 29.64% and 12% respectively. The allele frequencies of O, A, B and AB groups in the combined data were found to be 0.5354, 0.2022 and 0.2624 respectively. The distribution of Rh(D) group varies among the ABO blood groups. The Rh(D) positive allelic frequency was 0.8405 and the Rh(D) negative incidence was recorded as 02.55% in the studied population

Ant Species Richness Around Amravati City Maharashtra, India

Ants deserve a special place in the study of ecology, including behavior, given their species richness, social habits, and high densities, contributing to much of the animal biomes on earth (Gadagkar et.at. 1993). As ants can be studied virtually everywhere from forest interiors below ground, right up to the kitchen, we attempted a study to assess the ant species richness in a variety of habitats in and around Amravati city. The prime objective of this study is to prepare a partial checklist of ants of Amravati and to compare species richness between selected study sites. Eight study sites with different levels and types of vegetation were selected for the study.
We employed an “all out search” method for collection in the months of June and July 2010. Ants were hand collected using a brush and forecep during the day time for 6 hrs at each study site. Collected samples were preserved in 70% alcohol in the Department of Zoology, Govt. Vidarbha Institute of Science & Humanities, Amravati.
We identified Ants up to the genus level by using a Stemi DV4 Stereo microscope based on taxonomic keys of (Holldobles & Wilson, 1990; Bolton, 1994; Mathew & R.N. Tiwari, 2000).
During the present study a total of 34 species of 20 genera have been recognized from Amravati city representing five subfamilies namely Myrmicinae, Formicinae, Ponerinae, Dolichoderinae and Pseudomyrmicinae. Out of this subfamily, Myrmicinae is the most abundant having 11 genera including the genus Rhoptromyrmex. It has been recorded for the first time in this region, followed by Formicinae with four genera for being recorded for the first time as genus Oecophylla. Subfamily Ponerinae and Dolichoderinae were recorded only with two genera each; while the subfamily Pseudomyrmicinae where recorded very poorly with only one genera from G.V.I.S.H. campus.
Few ant genera such as Crematogaster and Myrmicaria of subfamily Myrmicinae, Camponotus and Polyrhachis of subfamily Formicinae and Leptogenys of subfamily Ponerinae were mostly found in all the habitats and most localities. Few genera are confined to few localities or habitat types, such as Rhoptromyrmex and Oecophylla recorded only from Pohara forests. Genus Tetraponera of subfamily Pseudomyrmicinae were collected from the tree trunk of Azadirakhta indica in the G.V.I.S.H. campus. 
Comparison of ant species distribution between the different study sites revealed that ant species richness was highest in Pohara forest with 28 species & lowest with 9 species around urban areas. Relatively high ant species richness was recorded at all the study sites such as the Agriculture field, Tree plantation area, and the Wadali and Chhatri Garden. On the other hand, ant species richness was low around urban houses compared to rural houses due to little or no vegetation and high levels of disturbance. The tree plantation site, roads, and pavement showed higher numbers of ant species compared to around urban areas probably due to road side richness of tree plantation.
From this study we conclude that due to availability of food and shelter, richness of ant species increases in forest and tree plantation areas. The number of ant species declines in low vegetative areas including urban areas. It is possible to study the ecology and biodiversity of living faunas by the studying the habitats of ants. The environs of Amravati city are rich in Ant fauna which deserve further study

Monopole Percolation in the Compact Abelian Higgs Model

We have studied the monopole-percolation phenomenon in the four dimensional Abelian theory that contains compact U(1) gauge fields coupled to unitary norm Higgs fields. We have determined the location of the percolation transition line in the plane $(\beta_g, \beta_H)$. This line overlaps the confined-Coulomb and the confined-Higgs phase transition lines, originated by a monopole-condensation mechanism, but continues away from the end-point where this phase transition line stops. In addition, we have determined the critical exponents of the monopole percolation transition away from the phase transition lines. We have performed the finite size scaling in terms of the monopole density instead of the coupling, because the density seems to be the natural parameter when dealing with percolation phenomena.Comment: 13 pages.

Monopole Percolation in pure gauge compact QED

The role of monopoles in quenched compact QED has been studied by measuring the cluster susceptibility and the order parameter $n_{max}/n_{tot}$ previously introduced by Hands and Wensley in the study of the percolation transition observed in non-compact QED. A correlation between these parameters and the energy (action) at the phase transition has been observed. We conclude that the order parameter $n_{max}/n_{tot}$ is a sensitive probe for studying the phase transition of pure gauge compact QED.Comment: LaTeX file + 4 PS figures, 12 pag., Pre-UAB-FT-308 ILL-(TH)-94-1

Antimicrobial activity of Acacia nilotica (L.) Del. plant extracts against Xanthomonas malvacearum bacteria

An experiment was conducted to check antibacterial activity of leaf bark and root extracts of Acacia nilotica (L.) Del. Plant against Xanthomonas malvacearum bacteria using agar well diffusion method expressed by zone of inhibition in mm in diameter. Antimicrobial activity of leaf, bark, and root extracts were separately assessed in triplicates for aqueous extracts, ethyl alcohol extracts. The results were compared with standard concentrations of antibiotics streptomycin and tetracycline. The ethyl acetate extracts of root seems to contain antibacterial component more than pure antibiotic with the concentration of 500 ug /ml

Phase field theory modeling of CH4/CO2 gas hydrates in gravity fields

Natural gas hydrates in reservoirs are thermodynamically unstable due to the interactions with surrounding fluids (aqueous, gas) and mineral surfaces. Depending on the local flow hydrate will dissociate as well as reform. If the dissociation rate is faster than the capacity of the surrounding fluids to dissolve the released gas, the gas will form bubbles. Depending on the rate of released gas and possible fracture patterns this may lead to venting of gas. The proper implementation of hydrodynamics will provide a deeper insight of the hydrate kinetics involved during dissociation and formation processes which involve hydrate former phase as smaller or larger bubbles or even continuous gas phase. In this work the phase field theory coupled with hydrodynamics model is implemented with variable density using the relative composition, phase field parameter and flow, which is an extension of our previous work which considers a constant density.publishedVersio

Takayasu\u27s arteritis presenting as ischemic stroke--case report

Takayasu’s Arteritis is a chronic, idiopathic, inflammatory disease that primarily affects large blood vessels such as aorta and its branches.1 Neurological symptoms occur in about 50% of cases but stroke occurs in about 10% of patients with Takayasu’s Arteritis2 . We report two such cases and emphasize the need for thorough evaluation of young patients with stroke to establish the underlying etiology

An investigation of oral sex as a risk factor for recurrent vaginitis: a case study

Background: Recurrent Vaginitis is defined as having three or more confirmed episodes within a year. Recurrence rates of vaginitis have been reported in up to 60% of previously infected women. The most common bacterial cause is due to Gardnerella vaginalis, while Candida albicans is the most common fungal cause; both microorganisms can cause opportunistic infections when imbalances occur in the vaginal environment. Commonly known risk factors include multiple sex partners, unprotected sex, douching, recent antibiotic use, and estrogen therapy. Case Presentation: A healthy 34-year-old female is complaining of recurrent episodes of vaginitis since the birth of her son two years ago. Vaginal irritation is typically accompanied by thick off-white vaginal discharge. She attributes her recurring symptoms to her intrauterine device (IUD) placed six-weeks postpartum. Symptoms occur after sexual intercourse, approximately once or twice a month. Her husband has incorporated oral sex into their routine sexual practice to help counteract the reduced libido she developed since having their son. She is married and monogamous with her husband. She has no prior history of sexually transmitted infection. She denies fevers, unintentional weight change, menstrual irregularity, rash or genital lesions, dyspareunia, or urinary complaints. Her vital signs are within normal range. A pelvic exam reveals mild suprapubic tenderness, erythema of the vaginal introitus, and thick off-white vaginal discharge with slight odor. No abnormal masses or cervical motion tenderness are noted on the bimanual exam. Urinalysis shows leukocyte esterase. Urine pregnancy test is negative. Vaginal swabs for gonorrhea and chlamydia are negative. Clue cells are seen on saline wet mount, and pseudohyphae with budding yeast are noted on potassium hydroxide preparation. For her concurrent bacterial vaginosis and Candidal vaginitis, she is prescribed a week of oral metronidazole 500 mg twice daily, and one dose of oral fluconazole 150 mg, respectively. Additionally, her husband is advised to thoroughly gargle with mouthwash prior to engaging in oral sex. On follow-up, the patient reports no further postcoital vaginitis episodes. Discussion: Current data is inconsistent regarding whether oral sex is considered a risk factor for recurrent vaginitis. The lack of research in this area could be due to the sensitive nature of discussing detailed sexual practices with patients, but these discussions provide a significant part of a patient’s history. Anecdotal evidence from our patient case prompted further investigation into the interactions between oral sex and recurrent vaginitis. An extensive literature review suggests that dysbiosis in vaginal flora resulting in vaginitis may be due to the direct inoculation of oral microbes, or the indirect effects of their byproducts. Furthermore, studies have shown that the use of mouthwash can effectively eliminate oral flora known to impact the vaginal microbiota. We plan to conduct a meta-analysis to further investigate the effects of varying vaginal and oral flora compositions on many aspects of the vaginal environment. A future case-control study can also be done to investigate the effectiveness of using mouthwash prior to oral sex for the prevention of recurrent vaginitis

CT and MR imaging in young stroke patients

Background: This study investigates the role of CT and MR imaging in the diagnosis and management of young stroke patients. Methods: CT scan findings of 108 patients and MR findings of 30 patients between 15-45 years of age were reviewed retrospectively. The variables included the territory of infarct on CT and MR imaging, the cortical distribution and size of infarct. Results: About 80% of the patients had infarcts of the carotid territory and 20% the vertebro-basilar distribution. More than half of the infarcts were cortical (56%). The yield of MR imaging was much higher for deeper structures such as basal ganglia, thalamus and brainstem. In half the cases, the infarct size was more than 3 cm. CONCLUSION: The ratio of carotid to vertebro-basilar infarcts was similar to that reported previously. A large proportion of the carotid territory infarcts were cortical. Deeper infarcts were better imaged with MR scan. There was a high proportion of large infarcts

A Validation of the p-SLLOD Equations of Motion for Homogeneous Steady-state Flows

A validation of the p-SLLOD equations of motion for nonequilibrium molecular dynamics simulation under homogeneous steady-state flow is presented. We demonstrate that these equations generate the correct center-of-mass trajectory of the system, are completely compatible with (and derivable from) Hamiltonian dynamics, satisfy an appropriate energy balance, and require no fictitious external force to generate the required homogeneous flow. It is also shown that no rigorous derivation of the SLLOD equations exists to date
