Abstract Essential oils produced from a population of Artemisia vulgaris Vietnamese origin cultivated near Hanoi were subjected to analysis by GC, GC/MS and 13C-NMR. The found contain oxygenated monoterpenes as major components (1,8-cineole, camphor α-terpineol). composition these differed that previously reported for A. oil. Only slight differences in the oil observed along vegetative life plant. No significant difference was between compositions leaf flower oils. In addition, combination...
Observations of 12CO(3–2) emission the circumbinary envelope Mira Ceti, made by Atacama Large Millimetre/sub-millimetre Array, are analysed. The observed Doppler velocity distribution is three components: a blueshifted south-eastern arc, which can be described as ring in slow radial expansion, ∼1.7 km s−1, making an angle ∼50° with plane sky and born some 2000 years ago; few arcs, probably at same epoch all sharing velocities redshifted approximately 3±2 s−1 respect to main star; thirdly,...
<h2>Abstract</h2> The Red River Delta is considered one of the largest megadelta systems in Asia. formation this delta has been controlled by continent-ocean interaction and sea-level fluctuation during Cenozoic. In study, we present a new sequence stratigraphic framework based on borehole lithofacies analysis high resolution seismic data. Late Pleistocene–Holocene sediments coastal zone were subdivided into three tracts: (1) lowstand tract (LST) characterized Pleistocene alluvial silty sand...
Observations by the Atacama Large Millimetre/sub-millimetre Array of 358 GHz continuum emission gravitationally lensed quasar host RX J0911.4+0551 have been analysed. They complement earlier Plateau de Bure Interferometer observations CO(7-6) emission. The good knowledge lensing potential obtained from Hubble Space Telescope makes a joint analysis three emissions possible. It gives evidence for source to be concentric with within 0.31 kpc and 1.10 kpc. also provides measurement size source,...
The unprecedented quality of the observations available from Atacama Large Millimetre/sub-millimetre Array (ALMA) calls for analysis methods making best them. Reconstructing in space morphology and kinematics radio sources is an underdetermined problem that requires imposing additional constraints its solution. hypothesis rotational invariance about a well-defined star axis, which good approximation to description gas envelopes many evolved stars protostars, particularly efficient this role....
A small radio telescope (SRT) has been installed on the roof of Hanoi astrophysics laboratory VATLY. It is equipped with a 2.6 m diameter mobile parabolic dish remotely controlled in elevation and azimuth super-heterodyne detection around 21 cm hydrogen line. First results observations Sun centre Milky Way are presented. They demonstrate high quality performance used to evaluate lobe size, signal noise ratios, anthropogenic interferences measurement accuracies. Particular attention given...
A new parameterization for calculating the nonlinear near-bed wave orbital velocity in shallow water was presented. The equations proposed by Isobe and Horikawa (1982) were modified order to achieve more accurate predictions of peak velocities. Based on field data from Egmond Beach Netherlands, correction coefficient maximum skewness determined as functions Ursell number. obtained validated against measurements Beach, with laboratory small-scale flume experiments at Delft University...
Observations of an unprecedented quality made by ALMA on the Red Rectangle CO(3-2) and CO(6-5) emissions are analysed jointly with aim obtaining as simple possible a description gas morphology kinematics. Evidence is found for polar conical outflows broad equatorial torus in rotation expansion. Simple models both proposed. Comparing provides evidence strong temperature enhancement over outflows. Continuum emission (dust) seen to be enhanced region. Observed asymmetries briefly discussed.
Using Atacama Large Millimeter/submillimeter Array observations of the C18O(2–1) line emission gas envelope protostar L1527, we have reconstructed its morphology and kinematics under assumption axisymmetry about west–east axis. The main original contribution to our understanding formation process L1527 is presentation a simple 3D parametrization based solely on regions that are not dominated by absorption. In explored range (∼0.7 5 arcsec from star), model reproduces better than earlier...
We present high-resolution Atacama Large Millimeter/submillimeter Array (ALMA) observations of the CO(3–2) and 350 GHz continuum emissions debris disc 49 Ceti, known to be particularly rich in molecular gas spite its age. The main new results are as follows: i) both CO dust discs share same position angle inclination but is more homogeneous, central thinner than disc; (ii) evidence obtained for a significant deficit observed emission at Doppler velocities differing from star systemic...
Building ancestral recombination graphs (ARG) with minimum number of events for large datasets is a challenging problem. We have proposed ARG4WG and REARG heuristic algorithm constructing ARGs thousands whole genome sequences. However, these algorithms do not result in minimal events. In this work, we propose GAMARG algorithm, an improvement ARG4WG, to optimize the ARG building process. Experiment different showed that outperforms other datasets. It also much better than comparable...
Raw coconut jelly is a popular byproduct of the processing industry in Asia Pacific which can enhance added economic value for local families rural area. However, production has resulted significant environmental impacts, particularly to aquatic environment due its heavily polluted wastewater e.g. very high values COD (up 120,000 mg/l), total nitrogen 1,740 and phosphorus 64 mg/l). The available treatment technology for such type likely be not economically efficient small-scale at craft...

We analyse ALMA observations of the 12CO(3-2) emission circumstellar envelope (CSE) Mira variable binary star W Aql. These provide, for first time, spatially resolved Doppler velocity spectra CSE up to angular distances central ∼ 5'' (meaning some 2000 AU). The exploratory nature (only five minutes in each two different configurations) does not allow a detailed modelling properties but provides important qualitative information on its morphology and kinematics. Emission is found be enhanced...
