The morphology of –ly and the categorial status of ‘adverbs’ in English.
No full textThe author challenges the traditional assumption of derivational morphology which accords adverbial –ly derivational status and gives adverbs lexical category status on a par with nouns, verbs and adjectives.
The author argues that adverbial –ly, unlike its adjectival counterpart, is inflectional and adverbs ending in –ly are rather to be regarded as inflected adjectives while those adverbs not containing –ly are uninflected adjectives; “adverbs cannot be categorially distinct from adjectives” (p. 342-343)
Shear Strength Measurements in LY-12 Aluminium Alloy During Shock Loading
No full textLateral stress of LY-12 alummium alloy under plate impact shock loading was measured. Based on the measured data, the Hugoniot relation and shear strength were obtained. The result has demonstrated that the shear strenath of the tested material increases remarkably with the increasing longitudinal stress. This means that the assumption of constant shear strength usually adopted in shock stress calculation is not suitable for the present material

No full textCommunity-based tourism (CBT) is no longer a new form in many countries, including Vietnam. However, the approach of CBT in a sustainable manner, especially in coastal villages, where tourism has recently emerged as an alternative livelihood, has received little attention. This study explores the impact of tourism on the lives of the local community, the level of people’s participation in tourism, and the challenges of tourism development in the coastal commune of Nhon Ly, Binh Dinh province. By utilizing a qualitative method such as observation and semi-structured interviews with 19 villagers engaged in tourism, the results show that tourism contributes significantly to the lives of the residents in Nhon Ly (e.g., improving income, changing livelihoods from fishing to tourism, improving environmental awareness). However, tourism development has obstacles related to local people’s skills and knowledge working in tourism and their limited participation in tourism policy and planning. Other issues were related to the negative impacts of tourism on cultural-social and environmental aspects in Nhon Ly. Therefore, there is a need for comprehensive coordination among all tourism stakeholders, building long-term strategies to overcome barriers toward sustainable CBT development in the future.</div

Hydrogen Ly α and Ly β Radiances and Profiles in Polar Coronal Holes
No full textThe hydrogen Lya plays a dominant role in the radiative energy transport in the lower transition region, and is important for the studies of transition-region structure as well as solar wind origin. We investigate the Ly alpha profiles obtained by the Solar Ultraviolet Measurement of Emitted Radiation spectrograph on the Solar and Heliospheric Observatory spacecraft in coronal holes and the quiet Sun. In a subset of these observations, the H I Ly beta, Si III, and O VI lines were also (quasi-)simultaneously recorded. We find that the distances between the two peaks of Ly alpha profiles are larger in coronal holes than in the quiet Sun, indicating a larger opacity in coronal holes. This difference might result from the different magnetic structures or the different radiation fields in the two regions. Most of the Ly beta profiles in the coronal hole have a stronger blue peak, in contrast to those in quiet-Sun regions while in both regions the Ly alpha profiles are stronger in the blue peak. Although the asymmetries are likely to be produced by differential flows in the solar atmosphere, their detailed formation processes are still unclear. The radiance ratio between Ly alpha and Ly beta decreases toward the limb in the coronal hole, which might be due to the different opacity of the two lines. We also find that the radiance distributions of the four lines are set by a combined effect of limb brightening and the different emission level between coronal holes and the quiet Sun.Astronomy & AstrophysicsSCI(E)7ARTICLE2L152-L15670
Influence of physical galaxy properties on Ly alpha escape in star-forming galaxies
No full textContext. Among the different observational techniques used to select high-redshift galaxies, the hydrogen recombination line Lyman-alpha (Ly alpha) is of particular interest because it gives access to the measurement of cosmological quantities such as the star formation rate (SFR) of distant galaxy populations. However, interpreting this line and calibrating such observables are still subject to serious uncertainties. Aims. In this context, it important to understand the mechanisms responsible for the attenuation of Ly alpha emission, and under what conditions the Ly alpha emission line can be used as a reliable star formation diagnostic tool. Methods. We used a sample of 24 Ly alpha emitters at z similar to 0.3 with an optical spectroscopic follow-up to calculate the Ly alpha escape fraction and its dependence upon different physical properties. We also examined the reliability of Ly alpha as a SFR indicator. We combined these observations with a compilation of Ly alpha emitters selected at z = 0-0.3 from the literature to assemble a larger sample. Results. We confirm that the Ly alpha escape fraction clearly depends on the dust extinction following the relation f(esc)(Ly alpha) = C-Ly alpha x 10(-0.4 E(B-V) kLy alpha) where k(Ly alpha) similar to 6.67 and C-Ly alpha = 0.22. However, the correlation does not follow the expected curve for a simple dust attenuation. A higher attenuation can be attributed to a scattering process, while f(esc)(Ly alpha) values that are clearly above the continuum extinction curve can be the result of various mechanisms that can lead to an enhancement of the Ly alpha output. We also observe that the strength of Ly alpha and the escape fraction appear unrelated to the galaxy metallicity. Regarding the reliability of Ly alpha as a SFR indicator, we show that the deviation of SFR(Ly alpha) from the true SFR (as traced by the UV continuum) is a function of the observed SFR(UV), which can be seen as the decrease in f(esc)(Ly alpha) with increasing UV luminosity. Moreover, we observe redshift dependence of this relationship, revealing the underlying evolution of f(esc)(Ly alpha) with redshift.IPE
Application of method of false transients to generate smooth grids around a body in motion
No full textA time marching finite difference scheme incorporating an efficient method of false transients, an approximate factorisation technique and a time steps cycling process, is presented for solution of a system of Poisson's equations. The solution to the equations provides a smooth three dimensional boundary fitted grid around a body in motion. The scheme required much less computational effort than that required by other iterative schemes. In closure, examples of a static grid around an aircraft tailplane and a dynamic grid around a flapping wing are presented.

STUDY ON THE TROPICAL-STORM-GENERATED WAVE FIELD ON THE SEA AREA AROUND LY SON ISLAND
No full textLy Son is a frontline island of our country that is often affected by adverse weather conditions such as monsoons or tropical storms. Studying the hydraulic parameters of tropical storms, including the storm's wave field, to determine extreme conditions plays an important role in forecasting, planning and construction of hydraulic works. The author uses the two-dimensional wave propagation model MIKE 21 SW to simulate the wave field of Molave storm 2020 in Ly Son sea. The results show a good agreement between the values obtained from the model and the actual measurements at Ly Son station. Based on the results obtained, the author proposes a method to simulate storm wave fields that is relatively accurate and effective. In particular, current standards based on wind speed and wind fetch still have many limitations. This is valuable in the actual design and planning of hydraulic works
