ABBREVIATIONS AND ACRONYMS ....................................................... 197 APPENDIX 1: APPLICATIONS AND IMPACT 1.1 Examples of Research Findings and Relation to SDGs Bangladesh Antibiotics in chicken SDG 3 – Good Health and Well-Being Food security The residue level of different antibiotics (tetracycline, oxytetracycline and chlortetracycline) were determined in broiler chicken meat, at a limit of quantification of 0.13-0.56 ng/g. The maximum residue levels (MRL) are 200 ng/g according to the Bangladesh Food Safety Authority (2017) and CODEX Alimentarius for human health protection. None of the antibiotics were detected in the meat samples. (IPICS BAN:04) Quality of azithromycin SDG 3 – Good Health and Well-Being Pharmaceutics Azithromycin is an antibiotic heavily used in Bangladesh for infections caused by bacteria. The quality of tablets from nine manufacturers was investigated, and the indicated content of the active ingredient was verified in all cases. (IPICS BAN:04) Contaminants in marine and fresh-water fish SDG 3 – Good Health and Well-Being Food security SDG 14 –Life Below Water Environmental Chemistry Thirteen marine fish and twelve fresh-water fish samples from different super markets in Dhaka were examined regarding the level of 20 organochlorine pesticides (OPCs), heavy metals, microplastics All OPCs were below the permitted level set by EC, 2004 and FAO/WHO, 2016. In the marine fish, all the metals concentrations were below the permitted limit set by FAO/WHO 2004 as well as the Bangladesh Food Act 1983 and Food Regulations 1985, whereas a few of the fresh-water fish had concentrations exceeding the MRLs. Eight of the marine fish samples were suspected to contain microplastics, and a variety of microplastics were identified in the fresh- water fish. (IPICS BAN:04) Contamination by leather industries SDG 6 – Clean Water and Sanitation Environmental Chemistry SDG 14 – Life Below Water Environmental Chemistry SDG 15 – Life on Land Environmental Chemistry Leather industries may pose serious threats to the environment due to the dumping of both solid and liquid wastes into the environment. In this study, chromium (Cr) concentrations of soil and water samples from Dhaleshwari river bank near to the Savar Tannery Estate (STE) were examined. The Cr was found to be significantly higher in soil (39 to almost 700 mg/kg) compared to water (< 0.005 mg/L). Water samples were collected from the surface level and may have been diluted due to the high flow in the river. (IPICS BAN:04) Antidiabetic effects of the plant Artemisia vulgaris SDG 3 – Good Health and Well-Being Medical chemistry In a chronic exposure experiment with rats, it was found that the ethanol extract of Artemisia vulgaris improves glucose metabolism. (IPICS ANRAP) 1 Antidiabetic effects of the plant Psidium guajava SDG 3 – Good Health and Well-Being Medical chemistry In a chronic exposure experiment with rats, it was found that the ethanol extract of Psidium guajava possesses antidiabetic activity. The plant extract stimulated insulin secretion, improved dyslipidemia and enhanced glycogenesis in the liver. (IPICS ANRAP) Test of medical instrumentation on patients in intensive care SDG 3 – Good Health and Well-Being Medical physics The Focused Impedance Method (FIM) (including Pigeon Hole Imaging, PHI), was further developed and used to monitor stomach emptying in 20 patients in an intensive care unit at a hospital. The new method gave correct results in 80% of the cases. Necessary computerised instrumentation was also successfully developed for this study.

Received 2019 November 6; in original form 2019 September 11 ABSTRACT We have analysed a selected sample of 36 Kepler short-cadence stars in the field of NGC 6811. The results reveal that all the targets are variable: two red giant stars with solar-like oscillations, 21 main-sequence pulsators (16 δ Scuti and five γ Doradus stars), and 13 rotating variables. Three new γ Doradus (γ Dor) variables (one is a hot γ Dor star) are detected in this work together with five new rotating variables. An in-depth frequency analysis of the δ Scuti (δ Sct) and γ Dor stars in the sample shows that the frequency spectra are very rich, in particular for the δ Sct-type variables. They present very dense frequency distributions and wide diversity in frequency patterns, even for stars being members of the cluster and with very similar location in the Hertzsprung–Russell (H–R) diagram.

The Kepler spacecraft is providing time series of photometric data with micromagnitude precision for hundreds of A-F type stars. Aims. We present a first general characterization of the pulsational behaviour of A-F type stars as observed in the Kepler light curves of a sample of 750 candidate A-F type stars, and observationally investigate the relation between γ Doradus (γ Dor), δ Scuti (δ Sct), and hybrid stars. Methods. We compile a database of physical parameters for the sample stars from the literature and new ground-based observations. We analyse the Kepler light curve of each star and extract the pulsational frequencies using different frequency analysis methods.

The Tycho-Gaia Astrometric Solution (TGAS) subset of the first Gaia catalogue contains an unprecedented sample of proper motions and parallaxes for two million stars brighter than G 12 mag. Aims. We take advantage of the full astrometric solution available∼ for those stars to identify the members of known open clusters and compute mean cluster parameters using either TGAS or the fourth U.S. Naval Observatory CCD Astrograph Catalog (UCAC4) proper motions, and TGAS parallaxes. Methods. We apply an unsupervised membership assignment procedure to select high probability cluster members, we use a Bayesian/Markov Chain Monte Carlo technique to fit stellar isochrones to the observed 2MASS JHKS magnitudes of the member stars and derive cluster parameters (age, metallicity, extinction, distance modulus), and we combine TGAS data with spectroscopic radial velocities to compute full Galactic orbits.

  • How the Tidal Evolution of Hot J Upiters Affects Transit Surveys of Clusters
    Too Little, Too Late: How the Tidal Evolution of Hot J upiters affects Transit Surveys of Clusters 1 John H. Debes1,2, Brian Jackson ,2 ABSTRACT The tidal evolution of hot Jupiters may change the efficiency of transit surveys of stellar clusters. The orbital decay that hot Jupiters suffer may result in their destruction, leaving fewer transiting planets in older clusters. vVe calculate the impact tidal evolution has for different assumed stellar populations, including that of 47 Tuc, a globular cluster that was the focus of an intense HST search for transits. vVe find that in older clusters one expects to detect fewer transiting planets by a factor of two for surveys sensitive to Jupiter-like planets in orbits out to 0.5 AU, and up to a factor of 25 for surveys sensitive to Jupiter-like planets in orbits out to 0.08 AU. Additionally, tidal evolution affects the distribution of transiting planets as a function of semi-major axis, producing larger orbital period gaps for transiting planets as the age of the cluster increases. Tidal evolution can explain the lack of detected exoplanets in 47 Tuc without invoking other mechanisms. Four open clusters residing within the Kepler fields of view have ages that span 0.4-8 Gyr~if Kepler can observe a significant number of planets in these clusters, it will provide key tests for our tidal evolution hypothesis. Finally, our results suggest that observers wishing to discover transiting planets in clusters must have sufficient accuracy to detect lower mass planets, search larger numbers of cluster members, or have longer observation \\'indows to be confident that a significant number of transits will occur for a population of stars.

Asteroseismology involves probing the interiors of stars and quantifying their global properties, such as radius and age, through observations of normal modes of oscillation. The technical requirements for conducting asteroseismology include ultrahigh precision measured in photometry in parts per million, as well as nearly continuous time series over weeks to years, and cadences rapidenough to sample oscillations with periods as short as afew minutes. We report on results from the first 43 days of observations, in which the unique capabilities of Kepler in providing a revolutionary advance in asteroseismology are already well in evidence.
