Formation of double ring patterns on Co2MnSi Heusler alloy thin film by anodic oxidation under scanning probe microscope

Double ring formation on Co2MnSi (CMS) films is observed at electrical breakdown voltage during local anodic oxidation (LAO) using atomic force microscope (AFM). Corona effect and segregation of cobalt in the vicinity of the rings is studied using magnetic force microscopy and energy dispersive spectroscopy. Double ring forma-tion is attributed to the interaction of ablated material with the induced magnetic field during LAO. Steepness of forward bias transport characteristics from the unperturbed region of the CMS film suggest a non equilibrium spin contribution. Such mesoscopic textures in magnetic films by AFM tip can be potentially used for memory storage applications.Comment: 7 pages, 5 figure

A rare case report on uterine perforation by levonorgestrel releasing intrauterine device

A levonorgestrel-containing intrauterine contraceptive devices are widely used in contemporary gynaecology, primarily as an effective method for contraception and for control of menstrual disorders like menorrhagia and dysmenorrhea. A case report of the uterine perforation by the levonorgestrel-releasing intrauterine device (LNG-IUD) in a 33-year-old asymptomatic woman after an 18-month of insertion. On routine cervical smear examination, the LNG-IUD threads were not visualised through the cervical os. After abdominal ultrasound scan the confirmation of perforated LNG-IUD was done and was removed laparoscopically

A comparative study to assess the efficacy of oral versus vaginal route of misoprostol in missed first trimester abortion

Background: Aim of the study to contrast the effectiveness of misoprostol taken oral vs vaginal method, for the management of missed abortion in the early trimester, and to acknowledge misoprostol value in cervical dilatation before any surgical pregnancy termination, Methods: Comparing the efficacy of misoprostol, by vaginal and oral routes, for termination of first trimester missed abortion was conducted in the department of obstetrics and gynaecology, at DR B. R. Ambedkar medical college and hospital, Bangalore. 2 groups were made as group A and group B which had 24 participants in each group and a total of 48 participants, in which group A was given misoprostol 400 mcg orally, maximum up to 3 doses and group B was given misoprostol 400 mcg maximum up to 3 doses and outcome was documented. Primary outcome expecting drug-induced complete expulsion of products of conception (POCs). Secondary outcomes measured were induction expulsion interval, number of doses required, classification of failures, cervical canal permeability in women requiring surgical evacuation, side effects. Results: Both oral and vaginal routes are highly effective (oral=75%, vaginal=91.7%, p=2.400), safe and acceptable with tolerable side effects. The mean time to expulsion was longer (10.55 hours) in the oral than vaginal group (8.09 hours). All unsuccessful cases, 2 in vaginal group and 6 in oral group had permeable cervices prior to surgical evacuation. Most of the side effects were tolerable in both groups. Conclusions: Vaginal route of misoprostol is more effective than oral misoprostol for first trimester missed abortion.

Comparative Experimental Study on Torsional Behavior of RC Beam Using CFRP and GFRP Fabric Wrapping

AbstractFiber reinforced polymer (FRP) as an external reinforcement is used extensively to enhance the strength requirement related to flexure and shear in structural systems. But the strengthening of members subjected to torsion is yet to be explored as Torsion failure is a brittle form of failure. In present experimental study deals with the torsional strengthening of Reinforced Concrete beams using epoxy bonded Fiber- Reinforced Polymer (FRP) fabric. Total Thirty nine rectangular beams of size 150mm × 300mm and 1200 in length are casted. Out of which, three beams are control beam and remaining thirty six beams are classified into two groups. One with CFRP fabric wrapping and another with GFRP fabric wrapping. With various wrapping patterns. The applied CFRP and GFRP configurations are U-jacketed, vertical strips with spacing, and edge strips along with vertical strips along its entire length. Torsional capacity of beams of two groups is compared with control specimen with respect to torsional moment, angle of twist and ductility factor and it was observed that CFRP fabric bonded beam shows more torsional strength than the GFRP bonded beam

Evaluation of Anti Asthmatic Activity of Urtica Dioica (Linn.) Leaves and Its Phytochemical Studies

Urtica dioica, often called common nettle, stinging nettle (although not all plants of this species sting) or nettle leaf, is a herbaceousperennial flowering plant in the family Urticaceae. It is native to Europe, Asia, northern Africa, and North America, and introduced elsewhere. The species is divided into six subspecies, five of which have many hollow stinging hairs called trichomes on the leaves and stems, which act like hypodermic needles, injecting histamine and other chemicals that produce a stinging sensation upon contact ("contact urticaria"). The plant has a long history of use as a source for traditional medicine, food, tea, and textile raw material in ancient societies. Urtica dioica is a dioecious, herbaceous, perennial plant, 1 to 2 m (3 to 7 ft) tall in the summer and dying down to the ground in winter.[1] It has widely spreading rhizomes and stolons, which are bright yellow, as are the roots. The soft, green leaves are 3 to 15 cm (1 to 6 in) long and are borne oppositely on an erect, wiry, green stem. The leaves have a strongly serrated margin, a cordate base, and an acuminate tip with a terminal leaf tooth longer than adjacent laterals. It bears small, greenish or brownish, numerous flowers in dense axillary inflorescences. The leaves and stems are very hairy with non-stinging hairs, and in most subspecies, also bear many stinging hairs (trichomes or spicules), whose tips come off when touched, transforming the hair into a needle that can inject several chemicals causing a painful sting or paresthesia, giving the species its common names: stinging nettle, burn nettle, burn weed, or burn hazel. AIM & OBJECTIVE: Synthetic drugs used for the treatment of asthma and allergy in India but more side effects are reported. Over the centuries, they are using medicinal herbs in daily life and approximately 6000 plants species are known to have medicinal properties in India. As per the literature survey will be expressed medicinal plants and traditional systems of medicines, Ayurveda, Yunani, Siddha and Homeopathy for the treatment of asthma and allergy but no scientific validation. Several literatures are indicated that the herbal drugs have lesser adverse effects when compared to synthetic drugs. The Urtica dioica is not scientifically validated and which was traditionally using herb. The work provides scientific validation for use of leaves against asthma by revealing the chemical compounds may be present in the plant. The present study is attempts to develop a novel plant based antihistamine work through antiastmatic drug which will be evaluated by in vitro and in vivo. CONCLUSION: This work will be useful to find new anti asthamatic drug with help of in vitro and in vivo models. Ethanolic extract will be possess highly substantial anti-asthmatic activity by significantly inhibited the histamine induced broncho constriction of guinea pig representing its H1 receptor antagonistic activity and support the plants by its anti-asthmatic properties. The results will be obtained in the study to be provide basic data for further progress and application of plant

Functional Outcome of the Distal Femur Locking Compression Plates in the Treatment of Fractures of Distal Femur

AIMS AND OBJECTIVES: Aim of this study is to evaluate the functional outcome of the distal femur locking Compression plates in the treatment of fractures of distal femur. OBJECTIVES: 1.Whether fractures reduction and fixation with locking compression plate will give acceptable results in the distal femur fractures treated in our setup. 2. To study the clinical outcome associated with this treatment modality 3. what are the potential complication associated with the procedure MATERIALS AND METHODS: This is a prospective, nonrandomised observational study of 14 Patients, with distal femur fractures (Muller A classification type 33 A,C) who were treated with DFLCP at Department of Orthopaedics, Coimbatore medical college hospital, Coimbatore from May 2013 to September 2014. The study sample was 14 patients and all these patients were included with predefined inclusion & exclusion criteria in this study. Minimum of 6 months and a maximum of 16 months follow up was done. The functional and radiographic results were recorded according to Neer’s criteria RESULTS: In this study, Most of the patients in this study were old patients in the age group 50-85 yrs. In this study 53% of the cases were Muller type A and 47% were type C and for three patients MIPPO technique was followed In our study in most of cases long working length was followed but in four patients short working length was used but we had no implant failure among these cases and Bone grafting was done for three patients The shortest follow up period was 3 months and longest period was 12 months , average union time was 4 months and most common Complications is knee stiffness which was almost 84 % of the patients with average knee motion was 25 degree of flexion,15% of the cases got infected. Shortening seen in 21% and no cases of implant failure in our study . In this study by the analysis of the results two cases with excellent results, 7 cases with good results and one cases with failure result. CONCLUSION: We conclude that DF-LCP, the “internal fixator” is a safe and reliable implant although careful preoperative planning and case selection and taking up cases for surgery as soon as possible are important factors which determine the final outcome. It may substitute a conventional plate and screw system(compression method) in treatment of complex distal femoral fractures especially in osteoporotic bone. As our study was limited by its small sample size and time duration so further randomised controlled studies are required in different situations to know the usefulness of this implant

Study on awareness and knowledge regarding Janani Suraksha Yojana (JSY) among ANC registered women in a primary health centre of tribal area of Thane District of Maharashtra

Background: In an attempt to make primary health care services available, especially, to the poorest and most vulnerable segments of rural & tribal society, JSY forms a crucial component of the NRHM. JSY is a safe motherhood intervention initiated to reduce maternal and neo-natal mortality and increasing institutional deliveries in them. Objective: 1) To assess awareness about Janani Suraksha Yojana (JSY) among ANC registered women. 2) To establish association of socio-demographic factors with awareness about Janani Suraksha Yojana (JSY).Methods: A cross sectional study was conducted in Primary Health Centre, Khardi of Thane district of Maharashtra during the period of Oct. 2010. A total of 110 ANC registered women were interviewed using pre-designed questionnaire. Results were analyzed by using SPSS version-15. Chi-square test was applied and p < 0.05 was considered as statistically significant. Results: More than half of the women (52.7%) were aware about this governmental scheme & only 17.24% of them were able to answer the correct name of the scheme. They obtained this knowledge mainly from the ANMs (58.6%), AWWs (22.4%) and ASHAs (17.2%). About 54.5% women had the knowledge about the components of JSY. Poor socioeconomic class, backward caste (SC/ST) & skilled/unskilled type of occupation were found to be significantly associated with the presence of knowledge about JSY. Conclusion: As the awareness and knowledge in our study group was less compared to other studies, there is a need to intensify the efforts to increase awareness and knowledge about JSY.
