Evaluation on the Corrosion of the Three Ni-Cr Alloys with Different Composition

Dental casting alloys are widely used in contact with oral tissue for many years now. With the development of new dental alloys over the past 15 years, many questions remain unanswered about their biologic safety. Concepts and current issues concerning the response to the biologic effects of dental casting alloys are presented. In this paper, samples of three commercially available nickel-chrome (Ni-cr) casting alloys (Dentaurum, Bego, Sankin) were taken to assess their corrosion behavior, using potentiodynamic polarization method (electrochemical method) with fusayama artificial saliva as an electrolyte medium to check for their biocompatibility. The parameters for corrosion rate and corrosion resistance were obtained from computer-controlled corrosion schematic instrument, namely, potentiostat through corrosion software (power CV). The results obtained were analyzed by classic Tafel analysis. Statistical analysis was done by Student's t-test and ANOVA test. It was concluded that Dentarum and Bego showed satisfactory corrosive behavior, with exception of Sankin which depicted higher corrosion rate and least resistance to corrosion. Thus, the selection of an alloy should be made on the basis of corrosion resistance and biologic data from dental manufactures

Drug utilization of antibiotics in post-operative cesarean section inpatients in tertiary care hospital: a prospective observational study

Background: The aim of this study is to evaluate the pattern and rational use of antibiotics in post-operative caesarean section (CS) inpatients in tertiary care teaching hospital, BIMS Belagavi.Methods: This cross sectional prospective observational study was conducted from December 2019 to February 2020, prior permission from institutional ethics committee was taken. Detailed data of post-operative caesarean section (CS) inpatients including age, diagnosis, line of management, complications and any adverse effects if occurred during the study was collected and entered in a specially designed proforma and MS word excel and analyzed by descriptive statistics like percentage.Results: Total 100 post-operative caesarean section inpatients were involved in the study. Most common indication for C-section was cephalopelvic disproportion. Average no of antibiotics per prescription was 3.32. Most commonly prescribed antibiotic was cefotaxime (27.71%) followed by gentamycin (25.90%) and metronidazole (24.59%). Majority (90%) of patients who admitted for ≤3 days (66%) had received combination antibiotic i.e., cefotaxime, metronidazole and gentamycin. IV fluids (21.21%) and analgesics (13.13%) were most frequently prescribed concomitant drugs. Majority (97.8%) of patients received parenteral preparation. 306 antibiotics (92.17%) used were from national model list of essential medicines (NLEM) and 332 antibiotics (100%). used were by generic name. Polypharmacy was 7.92.Conclusions: Cefotaxime was the most frequently prescribed antibiotic. Most of the antibiotics prescribed was rationally from NLEM and were by generic name

Extracting Interests of Users from Web Log Data Log

The knowledge on the cobweb is growing expressively. Without a recommendation theory, the clients may come through lots of instance on the network in finding the knowledge they are stimulated in. Today, many web recommendation theories cannot give clients adequate symbolized help but provide the client with lots of immaterial knowledge. One of the main reasons is that it can't accurately extract users interests. Therefore, analyzing users' Web Log Data and extracting users' potential interested domains become very important and challenging research topics of web usage mining. If users' interests can be automatically detected from users' Web Log Data, they can be used for information recommendation and marketing which are useful for both users and Web site developers. In this paper, some novel algorithms are proposed to mine users' interests. The algorithms are based on visit time and visit density which can be obtained from an analysis of web users' Web Log Data. The experimental results of the proposed methods succeed in finding users interested domains

Profitability of Cotton on a Pest Management Continuum in Guntur District of Andhra Pradesh

The plant protection response of farmers in the Guntur district of Andhra Pradesh has been examined with particular reference to the adoption of Bt cotton varieties and IPM components. The farmers have been found to follow a wide range of practices to manage the insect pests in cotton. The use of chemical insecticides has accounted for, about 37 per cent of the total variable costs. No significant reduction in plant protection expenditure has been recorded on adoption of Bt varieties without IPM practices. The adoption of IPM practices, however, has led to reduced use of insecticides and increased profitability. The saving on plant protection chemicals has more than compensated the cost of adopting IPM components. Consequently, the net returns have been found increased considerably from cotton cultivation.Crop Production/Industries,

Theoretical Study of Irradiation Effects in Close Binaries

The effect of irradiation is studied in a close binary systemassuming that the secondary component is a point source, moving in a circularorbit. The irradiation effects are calculatedon the atmosphere of the primary component in a 3-dimensional Cartesiancoordinate geometry. In treating the reflection effect theoretically, the totalradiation $(S_mathrm{T})$ is obtained as the sum of the radiation of 1) the effect ofirradiation on the primary component which is calculated by using onedimensional rod model $(S_mathrm{r})$ and 2) the self radiation of the primarycomponent which is calculated by using the solution of radiative transferequation in spherical symmetry $(S_mathrm{s})$. The radiation field is estimated alongthe line of sight of the observer at infinity. It is shown how the radiationfield changes depending on the position of the secondary component

STUDIES ON THROMBOLYTIC AND ANTI-HELMINTIC ACTIVITY OF Cocccinea grandis

Traditional system of medicine consists of large number of plants with various medicinal and pharmacological values and hence represents a priceless tank of new bio active molecules. Coccinea grandis belongs to the family Cucurbitaceae, is a rapidly growing, perennial climber or trailing vine. Traditionally different parts of this plant namely roots, leaves, and fruits are used in folklore medicine for several purposes like jaundice, diabetes, wound healing, ulcers, stomach ache, skin disease, fever, asthma, cough. Development of anthelmintic resistance and high cost of conventional anthelmintic drugs led to the evaluation of medicinal plants as an alternative source of anthelmintics.  As no scientific data was available on this plant hence, the present study was carried out for the investigation of antihelmintic activity and thrombolytic activity of bark of Coccinea grandis. Antihelmintic activity was done on pheritima posthuma. The results obtained were compared with standard albendazole and control groups respectively, the parameters evaluated are time of paralysis and time of death. On the other hand thrombolytic activity was done by using aqueous extract of Coccinea grandis bark. Thrombi or emboli can lodge in a blood vessel and block the flow of blood in that location depriving tissues of normal blood flow and oxygen. This can result in damage, destruction (infarction), or even death of the tissues (necrosis) in that area. Streptokinase is an antigenic thrombolytic agent used for the treatment of acute myocardial infarction, served as standard. This study was conducted on human blood sample and compared with standard and control groups respectively. The parameters studied are percentage of clot lysis. From the present study we found that various extracts of this plants showed significant thrombolytic and antihelmintic properties.Key words: thrombolysis, helminthes, coccinea, albendazole, streptokinase
