Multi level DVR with Energy Storage System for Power Quality Improvement

In this Paper, DVR of different voltage injection schemes is used to mitigate Sag, Swell and compensate Harmonics. The Reference Voltage signals are generated by SRF theory and unit vector template generation is used to estimate the load voltages. The performance of DVR is compared when BESS and Capacitor are used as source for the VSC. The power quality issues such as Sag, Swell and Harmonics are compensated using Multi level Neutral Point Clamped inverter based DVR employing SPWM, SVPWM modulation techniques. In order to evaluate the performance of DVR, simulations are carried out using MATLAB/SIMULINK software

A Survey on Secret Key Extraction Using Received Signal Strength in Wireless Networks

Secure wireless communications typically rely on secret keys, which are difficult to establish in an ad hoc network without a key management infrastructure. The channel reciprocity and spatial decorrelation properties can be used to extract secret key, especially in a Rayleigh fading channel. But the intervention of intermediate objects between the communication nodes reduces the strength of the secret key generated through such methods. Furthermore, the impact of small fluctuations also reduces the bit matching rate of such key agreement methods. This paper is based on the survey conducted on secret key generation from Received Signal Strength (RSS). By consider ing uniqueness property of RSS as base, various authors have proposed different methods for secret key extraction. Due to use of RSS for key extraction the existing systems suffer from predictable filter response at random period. The existing system also faces signal fading and drop in RSS because of intermediate object. By this survey we specify that even after generating high entropy bits for key extraction, there are considerable drawbacks in extracted key du e to intervention of intermediate objects and remarkable fading and drop in RSS

Efficacy of pregabalin versus nortriptyline in the treatment of chronic low backache with radiculopathy: an open label observational study

Background: The efficacy and safety of Pregabalin and Nortriptyline have been proved individually in low backache with radicular pain. However, there are limited number of studies comparing the efficacy of Pregabalin and Nortriptyline in Chronic Low Backache (CLBA) with radicular pain. Hence the present study was designed to determine the efficacy as well as tolerability of Pregabalin in comparison with that of Nortriptyline for reduction of pain in CLBA. The present study was an open label prospective observational study.Methods: Patients with CLBA, 15-60 years of age without specific cause and significant neurological deficit were included in the study. Severity of pain was assessed by Visual Analogue Scale (VAS). Patients were followed up at 2 and 4 weeks and their VAS scores and side effects were noted.Results: Both Pregabalin and Nortriptyline were effective in reducing pain, from baseline to 2 weeks and up to 4 weeks of treatment in chronic low backache with radicular pain, but there was no statistically significant difference between the two treatment groups. The incidences of side effects were less in the Nortriptyline treatment group as compared to Pregabalin.Conclusions: From the results of the present study it can be concluded that both Pregabalin and Nortriptyline were equally effective in the treatment of chronic low backache with radicular pain, but the incidence of adverse effects were more with Pregabalin as compared to Nortriptyline

Effect of turmeric and curcumin on BP-DNA adducts

Many human cancers that are widely prevalent today can be prevented through modifications in life-styles, of which diet appears to be an important agent. Several dietary constituents modulate the process of carcinogenesis and prevent genotoxicity. Many plant constituents including turmeric appear to be potent antimutagens and antioxidants. Therefore the modulatory effects of turmeric and curcumin on the levels of benzo[a]pyrene induced DNA adducts in the livers of rats were studied by the newly developed 32P-postlabelling assay method. Turmeric when fed at 0.1, 0.5 and 3% and the active principle of turmeric (curcumin) when fed at a level of 0.03% in the diet for 4 weeks significantly reduced the level of BP-DNA adducts including the major adduct dG-N2-BP, formed within 24 h in response to a single i.p. injection of benzo[a]pyrene. The significance of these effects in terms of the potential anticarcinogenic effects of turmeric is discussed. Further, these results strengthen the various other biological effects of turmeric which have direct relevance to anticarcinogenesis and chemoprevention

A study on association of thrombocytopenia with pregnancy induced hypertension

Background: Hypertension is common complication of pregnancy and contributes significantly to maternal and perinatal morbidity and mortality. With incidence of 5-7% of all pregnancy. Platelet count is the most simple and economical method of prediction of PIH, way before the derangements in PT, PTT and TT occur. This study sought the importance of platelet count as the most consistent and reliable method in predicting the severity of PIH. The aim and objectives of the study was to correlate severity of PIH with degree of thrombocytopenia and the degree of thrombocytopenia with fetal and maternal outcome.Methods: Prospective observational study was done during November 2014 to June 2015. A total of 100 cases were included in this period that was diagnosed as PIH. Investigations like platelet count, LFT, RFT, PT were done. Observations were tabulated, analyzed and conclusions were drawn.Results: 66% of all the cases had severe preeclampsia and 56% had thrombocytopenia. There was very high significant relationship between the degree of thrombocytopenia with the severity of the PIH (at p <0.001). 12% of the fetuses had IUD, 10% had IUGR, 4% died after birth and 2% had severe birth asphyxia. 5 % of the mothers had DIC, 3 % showing HELLP syndrome, and 1% died.Conclusions: Thrombocytopenia is the most common complications of PIH and at times is life threatening. Therefore, platelet count can be used as an early, simple, and rapid test to assess the severity of pre eclampsia and prevent progression to HELLP syndrome and DIC

Rare case report of metastatic cervical carcinoma

Although carcinoma of cervix is among the most common malignancies in women, cutaneous metastasis is very unusual. Here we report a case of a parous woman diagnosed with adenocarcinoma of cervix who did not undergo chemotherapy in spite of being advised after initial surgery, presenting with cutaneous metastasis at the operative scar site 2 years later

Development of new genomic microsatellite markers from robusta coffee (Coffea canephora Pierre ex A. Froehner) showing broad cross-species transferability and utility in genetic studies

<p>Abstract</p> <p>Background</p> <p>Species-specific microsatellite markers are desirable for genetic studies and to harness the potential of MAS-based breeding for genetic improvement. Limited availability of such markers for coffee, one of the most important beverage tree crops, warrants newer efforts to develop additional microsatellite markers that can be effectively deployed in genetic analysis and coffee improvement programs. The present study aimed to develop new coffee-specific SSR markers and validate their utility in analysis of genetic diversity, individualization, linkage mapping, and transferability for use in other related taxa.</p> <p>Results</p> <p>A small-insert partial genomic library of <it>Coffea canephora</it>, was probed for various SSR motifs following conventional approach of Southern hybridisation. Characterization of repeat positive clones revealed a very high abundance of DNRs (1/15 Kb) over TNRs (1/406 kb). The relative frequencies of different DNRs were found as AT >> AG > AC, whereas among TNRs, AGC was the most abundant repeat. The SSR positive sequences were used to design 58 primer pairs of which 44 pairs could be validated as single locus markers using a panel of arabica and robusta genotypes. The analysis revealed an average of 3.3 and 3.78 alleles and 0.49 and 0.62 PIC per marker for the tested arabicas and robustas, respectively. It also revealed a high cumulative PI over all the markers using both sib-based (10^-6and 10^-12for arabicas and robustas respectively) and unbiased corrected estimates (10^-20and 10^-43for arabicas and robustas respectively). The markers were tested for Hardy-Weinberg equilibrium, linkage dis-equilibrium, and were successfully used to ascertain generic diversity/affinities in the tested germplasm (cultivated as well as species). Nine markers could be mapped on robusta linkage map. Importantly, the markers showed ~92% transferability across related species/genera of coffee.</p> <p>Conclusion</p> <p>The conventional approach of genomic library was successfully employed although with low efficiency to develop a set of 44 new genomic microsatellite markers of coffee. The characterization/validation of new markers demonstrated them to be highly informative, and useful for genetic studies namely, genetic diversity in coffee germplasm, individualization/bar-coding for germplasm protection, linkage mapping, taxonomic studies, and use as conserved orthologous sets across secondary genepool of coffee. Further, the relative frequency and distribution of different SSR motifs in coffee genome indicated coffee genome to be relatively poor in microsatellites compared to other plant species.</p
