    Between October 2016 and February 2017 we imaged asteroid (22) Kalliope (10.3RC) a=243+/-6 km; P=11.5265+/-0.0204 d; T0=2457725.137+/-0.050; Pole[RA;Dec]=[ 96.2;-68.3]; e=0Roxane S/1 (PC) a=245+/-6 km; P=11.5858+/-0.0203 d; T0=2457721.631+/-0.051; Pole[RA;Dec]=[275.7;+68.8]; e= 0Roxane S/1 (RE) a=251+/-8 km; P=11.4927+/-0.0215 d; T0=2457717.730+/-0.126; Pole[RA;Dec]=[ 95.3; -67.8]; e=0.178+/-0.061ω=124+/-4Roxane S/1 (PE) a=249+/-7 km; P=11.5594+/-0.0190 d; T0=2457717.603+/-0.162; Pole[RADec]=[276.6+69.2]e=0.133+/-0.038ω= 230+/-5Roxane’s moon’s orbital pole is less than 4 degrees from the Ecliptic pole or Roxane’s orbital pole, but more than 22 degrees from Roxane’s rotational pole. Perhaps this indicates that the moon was captured from the Ecliptic plane rather than spun into Roxanne’s equatorial plane.The Starfire Optical Range’s 3.5 m telescope is the smallest ground based telescope used to derive orbits of asteroid satellites. Kalliope and Roxane follow our study of (87) Sylvia and its Romulus (Drummond, Reynolds, and Buckman (2016), Icarus 276, 107-115).

    A study was conducted at Marang River, Terengganu on determination of hydrological variation of Marang River at seven sampling stations. Sampling stations were selected along Marang River started from downstream to upstream. Each station was located 2 km apart from each other. Sampling was done twice; the first sampling was in 13 November 2012 (rainy season) and was repeated for second sampling on 24 February 2013 (dry season). Hydrological measurements of river such as velocity, river width and river depth were measured by using specific equipment. River velocity was measured by using flow meter (model FP101), river width was measured by using a range finder (model Bushnell 20-0001) and river depth was measured by using depth meter. Primary data of hydrological measurements of Marang River were measured and analyzed for each sampling station. Overall, station 1 shows the highest readings for most hydrological variables at both water tides during the first and second samplings. Station 1 that was located at the Marang River estuary identified by higher hydrological variables due to seawater movement during high tide as compared to stations 7 which located at the upstream. During dry season hydrological variables were slightly decrease since low freshwater flow from the upstream due to less rainfall intensity. (author)

    A study was conducted at seven sampling stations to determine water quality condition of Marang River, Terengganu. Each station was 2 km apart from each other, the first sampling was in 13 November 2012 and was repeated in 24 November 2013. The aim of the study is to determine water quality in spatial and temporal variation on different tides based on selected fourteen physicochemical parameters with regard to National Water Quality Standard. Six in-situ parameters such as pH, temperature, salinity, conductivity, DO and TDS were measured by using YSI 556 Multi parameters. Six ex-situ parameters such as sulphate, sodium, nitrate, phosphate, magnesium and turbidity also were measured. Sulphate, nitrate, phosphate and turbidity were analysed according to the standard method of analysis by Portable Data logging Spectrophotometer HACH DR/2010. Sodium and magnesium were analysed using Atomic Absorption Spectrophotometer. One way ANOVA shows that there are no significant changes between first sampling and second sampling, the data were average to give impression of water quality of Marang River in spatial and temporal perspective. Overall, water quality of Marang River was classified as class I to III according to NWQS classification, therefore Marang River needs proper water treatment for tolerant fish species and other aquatic water continuance.

  8. Genetic relatedness of low solitary nests of Apis dorsata from Marang, Terengganu, Malaysia.

    Directory of Open Access Journals (Sweden)

    Najmeh Sahebzadeh

    Full Text Available Knowledge on the population of genetic structure and ecological behaviour of Apis dorsata from Peninsular Malaysia is needed for effective management and conservation of this species since unsustainable whole solitary low nest cutting for product harvesting is the current common practice here. The analysis of 15 single locus DNA microsatellite markers on samples from 20 solitary nests of A. dorsata showed that while these markers were polymorphic, high intracolonial relatedness existed. Furthermore, in general, slightly negative values of intercolony relatedness (R among the nests of A. dorsata were found. However, positive values of mean intercolony relatedness were observed between 54 pairs of nests out of 190 possible combinations. The R values among nest pairs 3-4 and 3-5 was higher than 0.50 showing that their queens were half siblings, whereas nest pair 19-20 showed relatedness of 0.95 indicating that the same queen was sampled. The results that we obtained could not conclusively support the hypothesis of this study that the honey hunters in Marang district of Malaysia repeatedly harvest the same nest located at a different site and at a different time during the same honey harvesting season. However, our finding of an appreciable level of intercolonial relatedness between several pairs of nests in this pioneer study indicated that a comprehensive study with a larger sample size of solitary nests found throughout the region would be necessary to provide concrete proof for this novel idea.

    Full Text Available The creation and cohesion of the Roman empire owed much to the spread of literacy through the provinces and the use of texts as an instrument of government. An important manifestation of this is the role of the written word in the Roman army, exemplified by the diplomas that granted Roman citizenship and other privileges to auxiliary soldiers on completion of their military service. Margaret Roxan, one of the Institute's honorary research fellows, has studied these diplomas for many years, and her achievement was honoured at an international conference in London in May 2002.

  20. Evaluation of the Stability of Mercaptopurine Suspension Compounded in a Commercial Vehicle and the Determination of an Appropriate Beyond-use Date.

    Mercaptopurine is commonly used to treat acute lymphoblastic leukemia and has historically been commercially available only in tablet form. Since tablets may be difficult for children and elderly patients to swallow, many pharmacists have compounded mercaptopurine suspensions. The U.S. Food and Drug Administration recently approved a commercial suspension, but it is not widely available at this time. Therefore, pharmacists may still need to compound mercaptopurine suspension for use in areas where it is not available or if the commercial suspension is in short supply. Stability studies must be conducted in order to assign appropriate beyond-use dates for compounded preparations. The objective of this study was to evaluate the stability of extemporaneously compounded suspensions using commercially available mercaptopurine tablets, as well as active pharmaceutical ingredient in a vehicle of Ora-Sweet and Ora-Plus (1:1) stored in plastic and glass containers at room temperature. Each mercaptopurine preparation was analyzed using a validated stability-indicating high-performance liquid chromatography method at the following time points: 0, 7, 14, 21, 30, 60, and 90 days. Suspensions were also observed for changes in appearance or odor, and pH was tested at each time point. The suspension compounded from Roxane generic tablets was extremely viscous and was therefore eliminated from the study. All other suspensions showed no observed physical changes and maintained greater than 93% of initial concentration of mercaptopurine for the entire study period.

    There is a need for managing and displaying drug addiction phenomena and trend at both spatial and temporal scales. Spatial and temporal assessment on drug addiction in Terengganu was undertaken to understand the geographical area of district in the same cluster, in addition, identify the hot spot area of this problem and analysis the trend of drug addiction. Data used were topography map of Terengganu and number of drug addicted person in Terengganu by district within 10 years (2004-2013). Number of drug addicted person by district were mapped using Geographic Information system and analysed using a combination of multivariate analysis which is cluster analysis were applied to the database in order to validate the correlation between data in the same cluster. Result showed a cluster analysis for number of drug addiction by district generated three clusters which are Besut and Kuala Terengganu in cluster 1 named moderate drug addicted person (MDA), Dungun, Marang, Setiu and Hulu Terengganu in cluster 2 named lower drug addicted person (LDA) and Kemaman in cluster 3 named high drug addicted person(HDA). This analysis indicates that cluster 3 which is Kemaman is a hot spot area. These results were beneficial for stakeholder to monitor and manage this problem especially in the hot spot area which needs to be emphasized. (author)

    Full Text Available Los patrones de producción de hojarasca fueron estudiados en Pom-Atasta, un sistema estuarino asociado a la Laguna de Términos Campeche, México. Se seleccionaron cuatro rodales de manglar, contrastantes por sus condiciones de influencia de marea. Se colocaron al azar diez trampas en cada sitio para la colecta de hojarasca, estas fueron revisadas a intervalos mensuales durante un ciclo anual (1995-96. El material recolectado fue clasificado, secado y pesado. La floración de Avicennia germinans se presentó desde junio hasta septiembre; Rhizophora mangle presentó flores e hipocotilos todo el año. Los bosques más productivos fueron los ribereños dominados por A. germinans en la zona de menor influencia de marea, con condiciones hipohalinas de escasa variación anual y substratos limo-arcillosos. La producción promedio de hojarasca varió entre 1.8 y 4.5 g m-2 dìa-1. y respondió a los periodos climáticos de la región. En octubre de 1995 los ciclones Roxane y Opal se presentaron en la región y causaron una extraordinaria defoliación con aportes de hojarasca de 8 a 12 g m-2día-1 cifras que exceden a las registradas para manglares de México, del Caribe y del Ecuador. La tasa de renovación de follaje fue de 129-392 días.The patterns of mangrove litter production were studied in Pom-Atasta, a estuarine system linked to Terminos Lagoon, Campeche coast, Mexico. Four sampling sites with contrasting conditions of tidal influence were selected. Ten litter baskets placed randomly in each site for litter fall evaluation, were emptied monthly during an annual cycle (1995-1996. Litter material was classified, dried and weighed. The flowering season for Avicennia germinans was from June through September; Rhizophora mangle had flowers and hypocotyls year round. The most productive site was riverine forest dominated by A. germinans in the area with least tidal influence and hypohaline conditions, low annual salinity variation and lime-clay soils

    Full Text Available The aim of this study was to identify which attributes impacted the dynamic liking of cheese and wine individually, as well as when consumed together. Three wines (one white, Pouilly Loché; and two red, Maranges and Beaujolais and three cheeses (Comté, Époisses, Chaource were individually evaluated by a group of 60 consumers using mono-intake Temporal Dominance of Sensations (TDS with simultaneous hedonic ratings. The same data acquisition screen was used for all products showing a unique list of 14 descriptors (covering cheese and wine perception and a hedonic scale for dynamical rating of liking. The dynamic hedonic data were associated with the TDS profiles obtaining Temporal Drivers of Liking (TDL. Furthermore, the nine associations that resulted from combining each wine with each cheese were evaluated by multi-bite and multi-sip TDS. Individually, Chaource had practically no TDL; for Comté, mushroom flavor was a positive TDL, and in Époisses, salty was a negative TDL. As for wines, negative TDL were only found in the red wines: bitter, sour and astringent. Positive TDL for wines were: fruity, spicy and woody. Changes in the dynamic perception had a bigger impact on liking of wine compared to cheese. For the associations, the negative TDL were only three and mostly wine related: sour (for seven out of nine combinations, bitter (six out of nine and astringent (five out of nine. Positive TDL were more varied (a total of 10 descriptors and were related either to wine or cheese. As opposed to what was found in cheese alone, salty was a positive TDL in two of the combinations. It was observed that the dynamic sensory perception had a more important impact on liking in wine-cheese combinations than when consumed separately. TDS and TDL have a big potential in the study of food pairing, which should be further exploited.

    Body weight is highly associated with overall health status. Being severely thin or obese may impose the risk of many health problems. Early detection of body mass index (BMI) status may help to reduce the associated comorbidities. Although many studies in the literature have investigated the BMI of school adolescents in Malaysia, the data on status of body weight among school adolescents in suburban states like Terengganu is limited. This study aimed to describe the body weight status of the whole population of school adolescents in all seven districts in Terengganu, Malaysia. Using a cross-sectional study design, body weight and height were measured, and BMI was calculated and classified using WHO BMI-for-age Z-score. Data was obtained using the National Fitness Standard (SEGAK) assessment, which was uploaded in a specific Health Monitoring System (HEMS). From a total of 62,567 school adolescents, 50.7% were boys and 49.3% were girls. Girls had significantly higher BMI than boys in age groups of 13 to 15 and 16 to 17 years old. Among boys and girls, there were significant differences in mean BMI of school adolescents between rural and urban school locations in all age groups (p < 0.001). There were also significant differences in BMI between boys and girls in all districts in Terengganu, except Kemaman and Kuala Terengganu, for all age groups (p < 0.001). Overall, the prevalence of thinness, normal, overweight and obesity were 8.4, 64.6, 15.0 and 12.0%, respectively. There were significant differences between BMI categories and genders in total participants, and within rural and urban school locations (p < 0.05). In all districts except Marang and Dungun, significant difference was also found between BMI categories and genders. The prevalence of thinness, overweight and obesity in Terengganu were substantial. In this study, BMI category was associated with gender, age, school location and district. However, the actual effects of these factors on the

    relatively reduced and had methane as the dominant carbon species (XCO2 = 0.1-0.5). Application of our model to a recently published set of in-situ carbon isotope analyses for peridotitic diamonds from Marange, Zimbabwe (Smit et al., 2016), which contain CH4 fluid inclusions, allows us to perfectly match the observed co-variations in δ13 C, δ15 N and N content and at the same time explain the previously counter-intuitive observation of progressive 13C enrichment in diamonds that appear to have grown from a fluid with methane as the dominant carbon species. Similarly, the almost complete absence in the published record of progressive 13C depletion trends within diamonds likely reflects ubiquitous precipitation from CH4- and CO2-bearing water-rich fluids, rather than diamond formation exclusively by carbonate-bearing and CH4-free oxidized fluids or melts.
