The study of efficacy of injection iron sucrose in treatment of iron deficiency anemia in pregnancy

Background: Iron deficiency is the most common cause of anaemia in pregnancy amounting to almost 50% of pregnant ladies in India. All pregnant women, irrespective of haemoglobin status, should receive prophylactic doses of iron from second trimester. Iron sucrose has an advantage of being cost effective and readily available. The objective of this was to study the efficacy of injection Iron Sucrose in treatment of iron deficiency anaemia in pregnancy.Methods: About106 patients were given in injection iron sucrose in pregnancy, who had intolerance to oral iron or were non-compliant, in pre calculated (Ganzoni’s formula) doses and were followed up with rise in hemoglobin and ferritin after 6 weeks and at term.Results: Statistically significant increase in hemoglobin levels was observed at 6 weeks after initiation of treatment (9.689±0.821 gm% vs 10.906±0.775 gm%) as well as at term (mean 10.981±0.690 gm%). The serum ferritin levels too increased significantly at term (26.7 ng/mL±12.92 vs 65.34 ng/mL±15.73).Conclusions: Present study demonstrates that iron sucrose is an excellent option to treat iron deficiency anemia in patients where oral iron therapy has either failed or not suitable. It significantly increases hemoglobin levels in the study population. It is readily available in the market and can be infused on an outpatient basis

Superconductivity at 5K in NdO0.5F0.5BiS2

We report appearance of superconductivity at 5K in NdO0.5F0.5BiS2 and supplement the discovery [1] of the same in layered sulfide based ZrCuSiAs type compounds. The bulk polycrystalline compound is synthesized by conventional solid state route via vacuum encapsulation technique. Detailed structural analysis showed that the studied compound is crystallized in tetragonal P4/nmm space group with lattice parameters a = 3.9911(3) {\AA}, c = 13.3830(2) {\AA}. Bulk superconductivity is established in NdO0.5F0.5BiS2 at 5K by both transport and magnetic measurements. Electrical transport measurements showed superconducting Tc onset at 5.2K and Tc ({\rho}=0) at 4.7K. Under applied magnetic field both Tc onset and Tc ({\rho} =0) decrease to lower temperatures and an upper critical field [Hc2(0)] of above 23kOe is estimated. Both AC and DC magnetic susceptibility measurements showed bulk superconductivity below 5K. Isothermal magnetization (MH) exhibited typical type II behavior with lower critical field (Hc1) of around 15Oe. Isothermal magnetization (MH) exhibited typical type-II behavior with lower critical field (Hc1) of around 15Oe. Specific heat [Cp(T)] is investigated in the temperature range of 1.9-50K in zero external magnetic field. A Schottky-type anomaly is observed at low temperature below 7K. This low temperature Schottky can be attributed to the change in the entropy of the system.Comment: 10 pages text + Figs (New Version):comments/suggestion welcome ([email protected]

Background: To evaluate the effectiveness of regime of thromboprophylaxis including soluble aspirin, pneumatic compression devices and early mobilization in prevention of deep vein thrombosis (DVT) with patients of proximal femoral fracture managed by internal fixation.Methods: The study was an observational study conducted at tertiary care hospital of Indian armed forces with sample size of n= 50, diagnosed case of fracture proximal femur and managed operatively with soluble aspirin and pneumatic compression devices and early mobilization. Patients were observed and evaluated periodically for 12 weeks post discharge with colour doppler assessment.Results: The findings at end of 2 Week, n=1 (2%, p<0.003) had findings suggested of DVT and n=49 (98%) had no signs of DVT. Next periodic evaluation at 6 weeks and 12 weeks n=50 (100% p<0.001) was devoid of any doppler findings suggestive of DVT.Conclusions: The observational prospective study demonstrated the triad of soluble aspirin, pneumatic compression and early mobilization were efficacious in prevention of DVT in surgically managed cases of fracture proximal femur

Phase separation of a magnetic fluid: Equilibrium phases and non-equilibrium kinetics

We study self-assembly in a colloidal suspension of magnetic particles by performing comprehensive molecular dynamics simulations of the Stockmayer (SM) model which comprises of spherical particles that are decorated by a magnetic moment. The SM potential incorporates dipole-dipole interactions along with the usual Lennard-Jones interaction, and exhibits a gas-liquid phase coexistence observed experimentally in magnetic fluids. When this system is quenched from the high-temperature homogeneous phase to the coexistence region, the non-equilibrium evolution to the condensed phase proceeds with the development of spatial as well as magnetic order. We observe density-dependent coarsening mechanisms - a diffusive growth law $\ell(t)\sim t^{1/3}$ in the nucleation regime, and hydrodynamics-driven inertial growth law $\ell(t)\sim t^{2/3}$ in the spinodal regimes. [$\ell(t)$ is the average size of the condensate at time $t$ after the quench.] While the spatial growth is governed by the expected conserved order parameter dynamics, the growth of magnetic order in the spinodal regime exhibits unexpected non-conserved dynamics. The equilibrium morphologies have density-dependent shapes which typically include the isotropic sphere and spherical bubble morphologies in the nucleation region, and the anisotropic cylinder, planar slab, cylindrical bubble morphologies in the spinodal region. The structures are robust and non-volatile and exhibit characteristic magnetic properties. For example, the oppositely magnetized hemispheres in the spherical morphology impart the characteristics of a {\it Janus particle} to it. The observed structures have versatile applications in catalysis, drug delivery systems, memory devices and magnetic photonic crystals to name a few.Comment: 12 pages, 8 figure

DELTA-R: a change detection approach for RDF datasets

This paper presents the DELTA-R approach that detects and classifies the changes between two versions of a linked dataset. It contributes to the state of the art firstly: by proposing a more granular classification of the resource level changes, and secondly: by automatically selecting the appropriate resource properties to identify the same resources in different versions of a linked dataset with different URIs and similar representation. The paper also presents the DELTA-R change model to represent the changes detected by the DELTA-R approach. This model bridges the gap between resource-centric and triple-centric views of changes in linked datasets. As a result, a single change detection mechanism will be able to support the use cases like interlink maintenance and dataset or replica synchronization. Additionally, the paper describes an experiment conducted to examine the accuracy of the DELTA-R approach in detecting the changes between two versions of a linked dataset. The result indicates that the accuracy of DELTA-R approach outperforms the state of the art approaches by up to 4%. It is demonstrated that the proposed more granular classification of changes helped to identifyup to 1529 additional updated resources compered to X.By means of a case study, we demonstrate the support of DELTA-R approach and change model for an interlink maintenance use case. The result shows that 100% of the broken interlinks were repaired between DBpedia person snapshot 3.7 and Freebase

Reducing the hygroscopic swelling in MEMS sensor using different mold materials

Today, Hygroscopic swelling is one of the biggest challenging problem of Epoxy mold compound (EMC) in packaging with Microelectromechanical system (MEMS) devices. To overcome this hygroscopic swelling problem of EMC and guard the devices, MEMS devices are molded in this paper with different Mold Compound (MC) i.e. titanium and ceramic etc. during their interconnection with the board. Also, a comparatively performance analysis of this various mold compound with MEMS pressure sensor has been studied in this paper at 60% humidity, 140 mol/m3 saturation concentration and 25 oC. It was observed that hygroscopic swelling does not take place in the titanium mold compound. But, titanium is very costly so we have to consider something cheaper material i.e. ceramic in this paper. The Hygroscopic swelling in Ceramic Mold Compound after 1 year is nearly 0.05mm which is very less than epoxy

INVESTMENT BEHAVIOUR AND AWARENESS AMONG TEACHERS OF PRIVATE COLLEGES

In India, unlike certain western countries, social security is a big concern. Investors are invariably faced with a dilemma as to where to put their money to get maximum yield. There has been a considerable surge in the investment options that are available to the investors. The investors need to decide their portfolio from the available pool of investment opportunities. But, the investors realize that the decision making process is not an easy task. Teaching community is busy with their own assignments of teaching, examinations, evaluations, coping with new syllabus, new subjects, etc. As such, they do not have enough time and scope for study into investment analysis and avenues. Now that, a majority of teaching community is in private sector, they have very less appetite for investments. This makes the situation worse and academicians are desperately in need of good investments to plan their retirement life. A proper understanding of money, and it’s worth, the open avenues for investment, various financial institutions, the rate etc., are essential to successfully manage one’s finance for achieving life’s goal. The study discusses about the marital status and other factors influencing the investment behaviour of college teachers towards different investment avenues with special reference to Bhopal. In this regard, this study will help us to know the investment pattern among the academicians in Bhopal, the investment behaviour and the extent of investment awareness amongst them. The study also aims to explore the risk return dynamics on the investment made by them. The data was collected by distributing a structured questionnaire to 100 teachers in different private UG and PG colleges. The major impact on nature and extent of savings depends on the level of income of teachers. The research shows that majority of the respondents are saving money, resorting to the traditional investment avenues, believing the same to be safer, considering unpredictable contingencies in the future. These main avenues of investment are bank deposits followed by gold, and the main purpose of investment is for education of children, and security after retirement
