Fungsi Tari Babangsai Dalam Upacara Aruh Ganal Di Desa Loksado Hulu Sungai Selatan Kalimantan Selatan

Tari Babangsai disajikan sebagai ungkapan rasa syukur dan rasa gembira atas berhasilnya panen padi. Tarian ini tersaji menjadi bagian tak terpisahkan dari pelaksanaan upcara Aruh Ganal. Kegembiraan masyarakat penyangga ini tampak terlihat dengan hadirnya masyarakat Loksado sebagai pelaku maupun penyelenggara upacara Aruh Ganal. Penyelengaraan upacara Aruh Ganal diadalan setahun sekali, sesuai dengan ketentuan masyarakat adat Loksado Hulu Sungai di Kalimantan Selatan. Kehadiran tari Babangsari dalam upacara Aruh Ganal berfungsi sebagai sarana upcara di satu sisi, dan di sisi yang lain juga untuk hiburan bagi masyarakat pelaku upacara sehingga dapat melaksanakan upacara secara berurutan selama tujuh hari tujuh malam. The Babangsaidance is performed as an expression of thankfulness and happiness due to the successful rice harvest. This dance is an inseparable part of the AruhGanalceremony. The joyfulness of the supporting community can be seen from the presence of the members of Loksado society as both the performers and organizers of the ceremony. The AruhGanalceremony is carried out once a year, that is in accordance with the rule of the society of the village of river upstream Loksado, south Borneo. The existence of the Babangsaidance in the AruhGanalritual ceremony functions as a means of ceremony on one hand, and as an entertainment for the society carrying out the ritual ceremony on the other. Consequently, the ceremony may take place continually for seven days and seven nights

Generalized vegetation map of north Merrit Island based on a simplified multispectral analysis

A simplified system for classification of multispectral data was used for making a generalized map of ground features of North Merritt Island. Subclassification of vegetation within broad categories yielded promising results which led to a completely automatic method and to the production of satisfactory detailed maps. Changes in an area north of Happy Hammocks are evidently related to water relations of the soil and are not associated with the last winter freeze-damage which affected mainly the mangrove species, likely to reestablish themselves by natural processes. A supplementary investigation involving reflectance studies in the laboratory has shown that the reflectance by detached citrus leaves, of wavelengths lying between 400 microns and 700 microns, showed some variation over a period of seven days during which the leaves were kept in a laboratory atmosphere

Generalization of the coupled dipole method to periodic structures

We present a generalization of the coupled dipole method to the scattering of light by arbitrary periodic structures. This new formulation of the coupled dipole method relies on the same direct-space discretization scheme that is widely used to study the scattering of light by finite objects. Therefore, all the knowledge acquired previously for finite systems can be transposed to the study of periodic structures.Comment: 5 pages, 2 figures, and 1 tabl

Study of charm and beauty mass spectra, semileptonic decays of B(s,c)B_{(s,c)} and Bc→J/ψ(ηc)+P(V){B_c} \to J/\psi ({\eta _c}) + P(V) in a phenomenological potential model

Using a non-relativistic potential model, we obtain the mass spectra, leptonic decay constants, and parameters of the Isgur-Wise function for the beauty and charm mesons. With the calculated quantities, we investigate purely leptonic decays of $B^+$, $B^{*}$, $B_c^+$, semileptonic decay modes ${B_{(s)}} \to {D_{(s)}}l\nu$ and ${B_c} \to {\eta _c}\ell \bar \nu$ for three lepton channels $e,\mu ,\tau$, and obtain the corresponding branching fractions. $\bar B_{(s)}^{} \to D_{(s)}^*l\bar \nu$ transitions are also studied. Next, we apply the form factors for spin zero and spin one transitions of $B_c$ to calculate the nonleptonic branching ratios of ${B_c} \to J/\psi ({\eta _c}) + P(V)$, where $P$ and $V$ stand for the $D_q^{* - }$ vector meson and the $D_q$ pseudoscalar meson, respectively. Our results are found to be in agreement with those obtained in the experimental and theoretical results

Human action recognition via skeletal and depth based feature fusion

This paper addresses the problem of recognizing human actions captured with depth cameras. Human action recognition is a challenging task as the articulated action data is high dimensional in both spatial and temporal domains. An effective approach to handle this complexity is to divide human body into different body parts according to human skeletal joint positions, and performs recognition based on these part-based feature descriptors. Since different types of features could share some similar hidden structures, and different actions may be well characterized by properties common to all features (sharable structure) and those specific to a feature (specific structure), we propose a joint group sparse regression-based learning method to model each action. Our method can mine the sharable and specific structures among its part-based multiple features meanwhile imposing the importance of these part-based feature structures by joint group sparse regularization, in favor of discriminative part-based feature structure selection. To represent the dynamics and appearance of the human body parts, we employ part-based multiple features extracted from skeleton and depth data respectively. Then, using the group sparse regularization techniques, we have derived an algorithm for mining the key part-based features in the proposed learning framework. The resulting features derived from the learnt weight matrices are more discriminative for multi-task classification. Through extensive experiments on three public datasets, we demonstrate that our approach outperforms existing methods

Perbandingan Daya Antioksidan Ekstrak Metanol Daun Tembakau (Nicotiana Tabacum L) Dengan Rutin Terhadap Radikal Bebas 1,1-diphenil-2-pikrilhidrazil (Dpph)

An experiment was done to compare the antioxidant activity of methanolic extract of tobacco leaves and rutin. This experiment was conducted by extracting methanolic extract of tobacco leaves with soxhletation method with methanol and measuring the absorbance of DPPH using spectrofotometry UV- Vis in λ 517 nm. The obtained data was analized by t-test with the confidence level 95%. The result showed that methanolic extract of tobacco leaves extract and rutin have the different of antioxidant activity. Key word: Antioxidant, 1,1-diphenil-2-pikrilhidrazil, methanolic extract of tobacco leafes, rutin

Evolution of a barotropic shear layer into elliptical vortices

When a barotropic shear layer becomes unstable, it produces the well known Kelvin-Helmholtz instability (KH). The non-linear manifestation of KH is usually in the form of spiral billows. However, a piecewise linear shear layer produces a different type of KH characterized by elliptical vortices of constant vorticity connected via thin braids. Using direct numerical simulation and contour dynamics, we show that the interaction between two counter-propagating vorticity waves is solely responsible for this KH formation. We investigate the oscillation of the vorticity wave amplitude, the rotation and nutation of the elliptical vortex, and straining of the braids. Our analysis also provides possible explanation behind the formation and evolution of elliptical vortices appearing in geophysical and astrophysical flows, e.g. meddies, Stratospheric polar vortices, Jovian vortices, Neptune's Great Dark Spot and coherent vortices in the wind belts of Uranus.Comment: 7 pages, 4 figures, Accepted in Physical Review

Economic Analysis of Working Waterfronts in the United States

Waterfront communities in the United States, whether rural or urban, recreational or industrialized, have been subject to economic, technological, ecological, and demographic changes that challenge their continued existence or development. The purpose of this study is to document the current status, contribution to regional economies, and future prospects of U.S. coastal communities in order help promote their long‐term economic prosperity. A review of the relevant literature on economic valuation of waterfront and ocean‐related economic activities found that previous studies usually evaluated only one particular economic sector or specific region. The present study attempts to provide a comprehensive evaluation of all ocean‐related economic activity for all coastal regions of the United States
