Quintessential inflation with canonical and noncanonical scalar fields and Planck 2015 results

We investigate two classes of models of quintessential inflation, based upon canonical as well as noncanonical scalar fields. In particular, introducing potentials steeper than the standard exponential, we construct models that can give rise to a successful inflationary phase, with signatures consistent with Planck 2015 results. Additionally, using nonminimal coupling of the scalar field with massive neutrino matter, we obtain the standard thermal history of the Universe, with late-time cosmic acceleration as the last stage of evolution. In both cases, inflation and late-time acceleration are connected by a tracker solution.Comment: 13 pages, 18 figures, minor clarifications added and refs updated, to appear in PR

: The difference increased knowledge and attitudes of mothers about oral hygiene through dental health education lecture with discussion groups and lectures with hands on. Dental health education will be more effective when started from the family by teaching the mothers about the importance of oral health maintenance. This study aims to determine the difference in the increased knowledge and the attitudes of mothers about oral hygiene through dental health education lecture with discussion groups and lectures with hands on. This study was a quasi-experimental design with pretest and post-test group design. The subjects of research were 95 mothers of children aged 6-8 years who met the inclusion criteria and divided into two groups. Group I in PPA IO-497 Benjamin Oebufu, Kupang (53 subjects) were given a lecture with discussion groups and group II in PPA IO-495 Alfa Omega Bakunase 2, Kota Kupang with total of 42 subjects were given a lecture with hands on. Measuring tool was a questionnaire. The analysis of data using Statistic Program for Social Science (SPSS) for a different test testing the T-test for normal distribution of data, while the Mann-Whitney test and the Wilcoxon Signed Rank test were for abnormal distribution data. The initial analysis on knowledge and attitudes obtained some comparable results in which there were no differences between treatment groups I and II (p > 0.05). The results of the analysis of mean differences between groups on post-test 1 and 2 showed some significant differences knowledge and attitudes in the treatment group II of the treatment group I (p < 0.05). The results of the analysis of the average increase showed the increased knowledge and attitudes were significant in both treatment groups. Delta analysis results from pre-test to post-test 1 and pre-test to post-test 2 showed the treatment group improved knowledge and attitudes II is higher than in the treatment group I (p < 0.05). Dental health education using lecture with hands on increased knowledge and attitudes about the subject of oral hygiene of the a lecture with discussion groups

A Simulation Study of Pilots\u27 Ability to Perceive Angular Motion under the Influence of Alcohol

The study consisted of experimental research to determine the effect of alcohol on the pilots’ ability to perceive angular motion. It was hypothesized that in the absence of visual cues, pilots’ thresholds of perceiving a change in angular motion is adversely affected by alcohol in the blood, thereby increasing the potential to enter a state of spatial disorientation. The experiments were designed to simulate a real time in-flight scenario, in a rotating flight simulator, where angular accelerations could be controlled and pilots’ thresholds of perceiving a change in angular motion could be measured. The study revealed that the subjects registered a significant deterioration of their ability to perceive a change in angular motion at low Blood Alcohol Contents (BA

Heating up the cold bounce

Self-dual string cosmological models provide an effective example of bouncing solutions where a phase of accelerated contraction smoothly evolves into an epoch of decelerated Friedmann--Robertson--Walker expansion dominated by the dilaton. While the transition to the expanding regime occurs at sub-Planckian curvature scales, the Universe emerging after the bounce is cold, with sharply growing gauge coupling. However, since massless gauge bosons (as well as other massless fields) are super-adiabatically amplified, the energy density of the maximally amplified modes re-entering the horizon after the bounce can efficiently heat the Universe. As a consequence the gauge coupling reaches a constant value, which can still be perturbative.Comment: 28 pages, 13 figure

A high-resolution mRNA expression time course of embryonic development in zebrafish.

We have produced an mRNA expression time course of zebrafish development across 18 time points from 1 cell to 5 days post-fertilisation sampling individual and pools of embryos. Using poly(A) pulldown stranded RNA-seq and a 3' end transcript counting method we characterise temporal expression profiles of 23,642 genes. We identify temporal and functional transcript co-variance that associates 5024 unnamed genes with distinct developmental time points. Specifically, a class of over 100 previously uncharacterised zinc finger domain containing genes, located on the long arm of chromosome 4, is expressed in a sharp peak during zygotic genome activation. In addition, the data reveal new genes and transcripts, differential use of exons and previously unidentified 3' ends across development, new primary microRNAs and temporal divergence of gene paralogues generated in the teleost genome duplication. To make this dataset a useful baseline reference, the data can be browsed and downloaded at Expression Atlas and Ensembl

Determining and modeling the dispersion of non point source pollutants in Lake Victoria: A case study of Gaba Landing site in Uganda

Lake Victoria is an important source of livelihood that is threatened by rising pollution. In this study, pollutants in runoff are characterized and their dispersion after they enter the lake is measured and modeled at different points in the study areas. The objective is to develop a one dimensional mathematical model which can be used to predict the nutrient (ammonia, nitrite, nitrate, and phosphate) dispersion distances within the lake. A comparison between rain period nutrient concentrations and dry period nutrient concentrations within the Lake showed an elevation in nutrient levels during the rainy season, with exception of nitrate. However, nitrate had high levels during the dry season. Ammonia was found to disperse to horizontal distances of 38 m; nitrite 45 m, with nitrate and phosphate each attaining distances of 34 m. Measured nutrient concentration within the Lake compared well with model estimations.Key words: Modeling, water quality, nutrients, lake Victoria
