    Radii of Starlikeness of Ratios of Analytic Functions with Fixed Second Coefficients

    No full text
    We introduce three classes of analytic functions with fixed second coefficients that are defined using the class P of analytic functions with positive real parts. The objective of this paper is to determine the radii such that the three classes are contained in various subclasses of starlike functions. The radii estimated in the present investigation are better than the radii obtained earlier. Furthermore, connections with previously known results are shown

    Diversity of Sodium Transporter HKT1;5 in Genus Oryza

    Asian cultivated rice shows allelic variation in sodium transporter, OsHKT1;5, correlating with shoot sodium exclusion (salinity tolerance). These changes map to intra/extracellularly-oriented loops that occur between four transmembrane-P loop-transmembrane (MPM) motifs in OsHKT1;5. HKT1;5 sequences from more recently evolved Oryza species (O. sativa/O. officinalis complex species) contain two expansions that involve two intracellularly oriented loops/helical regions between MPM domains, potentially governing transport characteristics, while more ancestral HKT1;5 sequences have shorter intracellular loops. We compared homology models for homoeologous OcHKT1;5-K and OcHKT1;5-L from halophytic O. coarctata to identify complementary amino acid residues in OcHKT1;5-L that potentially enhance affinity for Na+. Using haplotyping, we showed that Asian cultivated rice accessions only have a fraction of HKT1;5 diversity available in progenitor wild rice species (O. nivara and O. rufipogon). Progenitor HKT1;5 haplotypes can thus be used as novel potential donors for enhancing cultivated rice salinity tolerance. Within Asian rice accessions, 10 non-synonymous HKT1;5 haplotypic groups occur. More HKT1;5 haplotypic diversities occur in cultivated indica gene pool compared to japonica. Predominant Haplotypes 2 and 10 occur in mutually exclusive japonica and indica groups, corresponding to haplotypes in O. sativa salt-sensitive and salt-tolerant landraces, respectively. This distinct haplotype partitioning may have originated in separate ancestral gene pools of indica and japonica, or from different haplotypes selected during domestication. Predominance of specific HKT1;5 haplotypes within the 3 000 rice dataset may relate to eco-physiological fitness in specific geo-climatic and/or edaphic contexts

    Cancer narratives, communitas and liminality: A study of fictional cancer narratives and the formation of communitas

    No full text
    The present study is based on the qualitative exploration of Cancer narratives through the lens of Liminality, the theory that was proposed by Arthur Van Gennep. It was further explored by Victor Turner. The Cancer narratives also show that the cancer patients go through a mental condition called pre-liminal, liminal and post-liminal stages. The liminal stage proves, "a neither here nor there," kind of stage. The study also aims at finding out the how illness can bring a change in an individual's perspective of life. It also aims at finding out whether the disease has been studied in the right perspective. Besides how communitas helps in understanding the cancer condition because those who are not in the lethal range of cancer don't understand what a cancer sufferer has to go through. How cancer influences people of different age, gender and stages of life is also the objective of the study? How the doctors who treat cancer patients feel about their patients because the patients come to the doctor for hope and assurance

    Ocimum basilicum L. (Sweet Basil) is a medicinal herb used in traditional Indian and Chinese medicine to treat a variety of disease conditions including hypertension, and has well established antihypertensive effects among renovascular hypertensive rats. The aim of this study was to evaluate the antihypertensive effects of O. basilicum as adjunct in the management of stage 1 and 2 hypertensive patients. A double blind-randomized controlled trial was performed, with participants (n=24) randomized into a control and treatment group. Participants randomized into the control group (n=12) were given their prescribed antihypertensive medication plus placebo while those in the treatment group (n=12) were given their antihypertensive medication plus Ocimum basilicum L. capsules containing 128 mg of dried, powderized leaves once a day. Participants’ blood pressure (BP) was measured at baseline, 1 week, and 2 weeks of drug administration and the Mean Arterial Pressure (MAP) calculated. Results showed that systolic and diastolic BP in the treatment group measured from baseline, one and two weeks of drug administration are significantly different, whereas the control group had insignificant findings. Furthermore, the MAP in the control group (105.25±9.52 mm/Hg, 104.08±8.45 mm/Hg and 104.47±8.85 mmHg) were comparable while that in the treatment group (106.47±6.65 mm/Hg,100.89±9.99 mm/Hg, and 97.14±9.96 mm/Hg) showed significant lowering (p=<0.0001) over time by Repeated Measures-Anova with Bonferroni’s post-hoc test. The significant findings in this study support the antihypertensive action of Ocimum basilicum L. among humans which warrant further exploration. DOI: http://dx.doi.org/10.5281/zenodo.427494

    Review: Location Based Authentication to Mitigate Intruder Attack

    Abstract -Recently the use of online banking has been increased to perform various online banking transactions. On the other hand, it is been targeted by various attacks found at the client side. Lately, traditional security methods were not capable enough to tackle these attacks such as intruder attacks, phishing attacks, etc. Presently remote authentication is the most efficient technique used to protect various services, resources, security for the unauthorized use. In this paper we use three-factor authentication and upgrade this method by including the fourth factor. The main three factors are (a) password (b) smart-card, and (c) biometrics. The newly introduced fourth factor is "Where you are" (Location), which mainly consist of REAL TIME LOCATING SYSTEM technique and instant generated pin code mechanism for the verification of the user performing the transaction

    Robust estimation of bacterial cell count from optical density

    Optical density (OD) is widely used to estimate the density of cells in liquid culture, but cannot be compared between instruments without a standardized calibration protocol and is challenging to relate to actual cell count. We address this with an interlaboratory study comparing three simple, low-cost, and highly accessible OD calibration protocols across 244 laboratories, applied to eight strains of constitutive GFP-expressing E. coli. Based on our results, we recommend calibrating OD to estimated cell count using serial dilution of silica microspheres, which produces highly precise calibration (95.5% of residuals <1.2-fold), is easily assessed for quality control, also assesses instrument effective linear range, and can be combined with fluorescence calibration to obtain units of Molecules of Equivalent Fluorescein (MEFL) per cell, allowing direct comparison and data fusion with flow cytometry measurements: in our study, fluorescence per cell measurements showed only a 1.07-fold mean difference between plate reader and flow cytometry data

    A study to evaluate the effectiveness of planned teaching program in terms of knowledge regarding prevention of pressure ulcers and create awareness through posters, flashcards and pamphlet distribution among patient’s relatives at orthopedic ward in Vardhman Mahavir medical college and Safdarjung hospital. Quantitative and evaluative research approach and a single group pretest and post-test research design were adopted. The sample size was thirty patient relatives selected for their long stay at Orthopedic Department in Safdarjung hospital. Data was collected by using structured interview schedule. Pretest was conducted to assist the knowledge on bed-sore care followed by administration of planned teaching program. After two days post-test was conducted using same questionnaire. The study finding showed, after the administration of planned teaching program, post-test mean value ± SD i.e. 21.9 ± 3.99 was higher than the pretest mean value ± SD i.e. 12.1 ± 2.20. At 0.05 level of significant the calculated t value, i.e., 11.9 was more than the tabulated value i.e. 8.1. Hence, there was statistically significant difference between pretest and post-test knowledge scores and hence the hypothesis was accepted. There was no statistically significant (p>0.05) association between post-test knowledge scores and socio-demographic variable. The study concluded that planned teaching program was found to be effective in proving the knowledge of patient relatives regarding prevention of bed sore

    Degree of exposure to interventions influences maternal and child dietary practices: Evidence from a large-scale multisectoral nutrition program.

    The prevalence of maternal and child malnutrition in Nepal is among the highest in the world, despite substantial reductions in the last few decades. One effort to combat this problem is Suaahara II (SII), a multi-sectoral program implemented in 42 of Nepal's 77 districts to improve dietary diversity (DD) and reduce maternal and child undernutrition. Using cross-sectional data from SII's 2017 annual monitoring survey, this study explores associations between exposure to SII and maternal and child DD. The study sample included 3635 mothers with at least one child under the age of five. We focused on three primary SII intervention platforms: interpersonal communication (IPC) by frontline workers, community mobilization (CM) via events, and mass media through a weekly radio program (Bhanchhin Aama); and also created an exposure scale to assess the dose-response relationship. DD was measured both as a continuous score and as a binary measure of meeting the recommended minimum dietary diversity of consuming foods from at least 5 of 10 food groups for mothers and at least 4 of 7 food groups for children. We used linear and logistic regression models, controlling for potentially confounding factors at the individual and household level. We found a positive association between any exposure to SII platforms and maternal DD scores (b = 0.09; p = 0.05), child (aged 2-5 years) DD scores (b = 0.11; p = 0.03), and mothers meeting minimum dietary diversity (OR = 1.16; p = 0.05). There were significant, positive associations between both IPC and CM events and meeting minimum DD (IPC: OR = 1.31, p = 0.05; CM: OR = 1.37; p<0.001) and also between CM events and DD scores (b = 0.14; p = 0.03) among mothers. We found significant, positive associations between mass media and meeting minimum DD (OR: 1.38; p = 0.04) among children aged 6-24 months and between mass media and DD scores (b = 0.15; p = 0.01) among children aged 2-5 years. We also found that exposure to all three platforms, versus fewer platforms, had the strongest association with maternal DD scores (b = 0.45; p = 0.01), child (aged 2-5 years) DD scores (b = 0.41; p<0.001) and mothers meeting MDD (OR = 2.33; p<0.001). These findings suggest that a multi-pronged intervention package is necessary to address poor maternal and child dietary practices and that the barriers to behavior change for maternal diets may differ from those for child diets. They also highlight the importance of IPC and CM for behavior change and as a pre-requisite to mass media programs being effective, particularly for maternal diets
