    A mapping g:V\left(G\right)\rightarrow{k,k+1,\ldots,k+N-1} is a radio heronian mean k-labeling such that if for any two distinct vertices s and t of G, d\left(s,t\right)+\left\lceil\frac{g\left(s\right)+g\left(t\right)+\sqrt{g\left(s\right)g\left(t\right)}}{3}\right\rceil\geq1+D,for every s,t\in\ V(G), where D is the diameter of G. The radio heronian mean k-number of g, {rrhmn}_k(g), is the maximum number assigned to any vertex of G. The radio heronian mean number of G, {rhmn}_k(g), is the minimum value of {rhmn}_k(g) taken overall radio heronian mean labelings g of G. If {rhmn}_k(g)=\left|V\left(G\right)\right|+k-1, we call such graphs as radio heronian mean k-graceful graphs. In this paper, we investigate the radio heronian mean k-graceful labeling on degree splitting of graphs such as comb graph P_n\bigodot K_1, rooted tree graph {RT}_{n,n} hurdle graph {Hd}_n and twig graph\ {TW}_n.A  mapping    is a radio heronian mean k-labeling such that  if for any two distinct vertices  and  of , ,for every V(G), where  is the diameter of .

    Objective: Azelnidipine (AZEL) and Telmisartan (TELM) combination is referred to the sufferers of hypertension. No analytical process has yet been mentioned for the TELM and AZEL combination analysis. We, therefore, have designed for its first time stability demonstrating methodology based on HPLC for analysing TELM and AZEL in the tablets and bulk. Methods: The assay of TELM and AZEL was get done on a 250 mm length C18 column (Supelco, 4.6 mm inner diameter, 5.0 μm particle size), and utilized 0.1M Na2SO4 (pH 3.6) and acetonitrile (55% volume:  45% volume) as the mobile solvents phase, at a stream rate 1.0 ml/min. HPLC recognition of TELM and AZEL was taken by a photodiode array sensor set at 258 nm. For validation of the stability demonstrating methodology proposed in terms of sensitivity, precision, specificity, linearity, device adequacy, robustness and accuracy, ICH directives were followed. Results: Calibration curves of TELM and AZEL were generated in the array of 20-60 µg/ml and 4-12 µg/ml with recovery percentage ranges of 99.62%-101.05% and 97.76%-100.17%, and detection limits of 0.020 µg/ml and 0.009 µg/ml, respectively. TELM and AZEL stability was inspected in the existence of acid, base, light, heat, and oxidation and it was realised to be more stable under oxidation degradation testing conditions employed when compared to acid, alkaline, photo, and heat degradation testing conditions applied. Conclusion: The observations demonstrated that the described HPLC stability demonstrating methodology was suitable for quantitating TELM and AZEL combination in tablets and bulk

    A protease producing bacteria was isolated from meat waste contaminated soil and identified as Pseudomonas fluorescens. Optimization of the fermentation medium for maximum protease production was carried out. The culture conditions like inoculum concentration, incubation time, pH, temperature, carbon sources, nitrogen sources and metal ions were optimized. The optimum conditions found for protease production was 37°C at pH 9, with 2% inoculum in the medium for 24 h. Wheat bran and peptone stimulates the production of protease. Magnesium sulphate has less inhibitory effect among the metal ions tested

    INVESTIGATION OF TECHNIQUES FOR EFFICIENT & ACCURATE INDEXING FOR SCALABLE RECORD LINKAGE & DEDUPLICATION

    Get PDF
    Record linkage is the process of matching records from several databases that refer to the same entities. When applied on a single database, this process is known as deduplication. Increasingly, matched data are becoming important in many applications areas, because they can contain information that is not available otherwise, or that is too costly to acquire. Removing duplicate records in a single database is a crucial step in the data cleaning process, because duplicates can severely influence the outcomes of any subsequent data processing or data mining. With the increasing size of today’s databases, the complexity of the matching process becomes one of the major challenges for record linkage and deduplication. In recent years, various indexing techniques have been developed for record linkage and deduplication. They are aimed at reducing the number of record pairs to be compared in the matching process by removing obvious nonmatching pairs, while at the same time maintaining high matching quality. This paper presents a survey of variations of six indexing techniques. Their complexity is analyzed, and their performance and scalability is evaluated within an experimental framework using both synthetic and real data sets. These experiments highlight that one of the most important factors for efficient and accurate indexing for record linkage and deduplication is the proper definition of blocking keys

    Get PDF
    Studies on Thermal decomposition of ammonium perchlorarte(AP)- polystyrene(PS) propellant and burning rate of PS/AP propellant have been carried out as a function of oxidizer particle size. Thermal decomposition of AP and AP/PS propellant as function of AP particle size shows a maximum rate around 100 micro particle size which has been explained on the basis of Mample's theory. No such maximum is observed in the case of PS/AP propellant burning rate

    Background: Coronary artery disease (CAD) is a major cause of mortality and morbidity. Per Cutaneous Interventions (PCI) is emerging as the mainstay of treatment for CAD. Periprocedural myocardial necrosis, which can range from a low-level elevation of cardiac biomarkers to a large myocardial infarction, is an important complication of PCI. There are conflicting reports regarding peri-procedural biomarker elevation and adverse outcome. It is in this context we have undertaken this study to assess the prognostic significance of cardiac troponin T elevation after elective stent implantation.Methods: The study population included 100 consecutive patients who underwent elective PCI with stent implantation in cardiology unit of Medical College, Trivandrum. Serial cardiac enzyme levels were measured in all patients undergoing the procedure. CPK was measured at 8 hrs, 16 hrs and 24 hrs and Troponin T was measured at 8hrs and 24 hrs. post PCI. In hospital events were documented and patients were on follow up for a period of 1 year. Primary endpoints of death, myocardial infarction, recurrent ischemia leading to revascularization were noted.Results: In our study population of 100 patients there were 87 males and 13 females. Among them 50% had unstable angina, 18% had exertional angina and 32% were post myocardial infarction patients. In this group of hundred patients 79% had single vessel disease, 18% had two vessels and 3% had triple vessel disease. A total of 103 stents were deployed. Mean CPK levels were CPK-1 (80.11+36.19), mean CPK-2 (83.91± 34.8) and mean CPK-3 (86.32+57.80). Mean Troponin T-1 was 0.04+0.1 and mean Troponin-2 was 0.06+0.145. In this study, we compared late onset angina with Troponin and CPK positivity and found that both Troponin-1 & Troponin-2 had significant correlation with late onset angina.Conclusions: Periprocedural Troponin T is more sensitive than CPK in predicting late events. Thrombus containing lesions and bifurcation lesions were significantly associated with elevation in Troponin T. No significant Troponin T elevations were noted in patients with diabetes mellitus and those containing calcified lesions. Drug eluting stents were associated with a relatively lesser Troponin T elevations but not statistically significant

    Visible Light Communication (VLC) has become an accolade to its radio frequency counterpart. In VLC system, orthogonal frequency division multiplexing (OFDM) has drawn much attention, because of simple equalization, high spectral efficiency, high data rate and robustness to intersymbol interference (ISI). Besides, there are emerging applications that ought to be gotten with low latency and high reliability. To diminish power requirements with no transmission capacity extension, Trellis coded modulation (TCM) is utilized as a part of the framework in which the free distance of trellis diagram is equivalent to the minimum distance between the points of constellation focuses in partitioned subsets, which augments the coding gain up i.e. the performance parameter viably. TCM together with VLC-OFDM enhances the transmission execution in reasonable frameworks. In this paper, we propose OFDM which is based on TCM and is planned and exeuted for digitized OFDM frameworks by presenting delta sigma modulation (DSM) considering VLC channel. Simulation results show that the proposed TCM based VLC-OFDM offers incredible robustness against noises and nonlinear degradation
