Kontruksi Media Dalam Gerakan Islam Populis 212
Full text linkThis paper studied the movement of Aksi Bela Islam (ABI) which was propagated by the GNPF MUI group to bring down Basuki Tjahaja Purnama from the governor position. This demonstration not only in Jakarta but also the various cities in Indonesia. The involvement of Muslims are influenced by social media. Social media has succeeded in becoming a public sphere for society. Today, society can take a truth from social media. Therefore, social construction is not only formed from individuals or society but also social media. This research uses literature study with analytical descriptive writing method. This paper uses framing analysis approach and Islam populist. The results of this paper show that social media has an important role in the construction of public awareness. This social construction can be seen with the birth of Islam populist movement 212 which has a goal to reform the bureaucracy in government.Keyword: Social Contruction, Islam Populist, Aksi Bela Islam, Social Media, Post-Truth
Converting SrI <sub>2</sub> :Eu <sup>2+</sup> into a near infrared scintillator by Sm <sup>2+</sup> co-doping
No full text The luminescence and scintillation properties of SrI 2 single crystals doped with 5% Eu 2+ and 0.05%, 0.2% and 0.5% Sm 2+ are evaluated. X-ray excited and photoluminescence measurements show energy transfer from excited Eu 2+ ions to Sm 2+ ions. At a concentration of 0.5% Sm 2+ , the luminescence consists almost entirely of 740 nm emission from Sm 2+ 5d-4f transitions. Co-doping SrI 2 :5% Eu 2+ with Sm 2+ provides a novel method to bypass the self-absorption problem encountered in large SrI 2 :Eu 2+ crystals and, at the same time, provides a unique near-infrared emitting scintillator with a light yield of approximately 40,000 photons/MeV.

Crystal structure determination of new compounds Li6MB3O9 (M= Nd, Sm, Eu, Tm, Er)
No full textNew compounds Li6MB3O9 (M=Nd,Sm,Eu,Tm,Er) were synthesized by solid-state reaction. The crystal structure of Li6NdB3O9 was analyzed from both powder and single crystal X-ray diffraction data. The results obtained by powder diffraction analysis and Rietveld refinement are a=7.2725(4) angstrom, b=16.6398(9) angstrom, c=6.7529(5) angstrom, beta=105.398(8)degrees, and space group P2(1)/c, which agree with the results obtained by single crystal diffraction analysis: a=7.2712(4) angstrom, b = 16.6268 (9) angstrom, c = 6.7484(4) angstrom, beta=105.411 (1)degrees, and space group P2(1)/c. This compound is isostructural with Li6YB3O9, Single crystal structure analysis showed that the fundamental building unit of these isostructural compounds comprises three isolated [BO3](3-) triangles, one distorted [NdO8](13-) triangulated dodecahedron, four distorted [LiO5](9-) five-coordinated polyhedra, and two [LiO4](7-) tetrahedron. An analysis of the infrared spectrum of Li6NdB3O9 confirmed the presence of isolated [BO3](3-) triangles in Li6NdB3O9. The remaining four Li6MB3O9 (M=Nd, Sm, Eu, Tm, and Er) compounds were found to be isostructural with Li6NdB3O9. Their unit cell dimensions decrease with an increase in the atomic number of the rare-earth atoms. DTA and TGA measurements of Li6MB3O9 (M=Nd, Sm, Eu, Tm, and Er) revealed that these borates congruently melt from 800 degrees C to 860 degrees C.

INTERACTION MODE BETWEEN METHYLENE BLUE-Sm(III) COMPLEX AND HERRING SPERM DNA
No full textSpectroscopic and viscosity methods were applied to investigate the interaction between methylene blue (MB)-Sm(III) complex and herring sperm DNA by using acridine orange as a spectral probe in Tris-HCl buffer (pH 7.40). By means of molar ratio method, the binding ratios between MB-Sm(III) and DNA were determined as n(Sm(III):)n(MB) = 1:3, n(MB-Sm(III) complex:)n (DNA) = 8 : 1, and the apparent molar absorption coefficient of epsilon(MB-Sm(III)-DNA) was found to be 7.01x10(5) M-1.cm(-1). The bonding constants at different temperatures K-292K(0) = 7.35x10(5) M-1, K-310K(0) = 1.25x10(5) M-1 were obtained by double reciprocal method. Thermodynamic function computation demonstrates that Delta rSm(circle minus) is the primary driving power of the interaction between MB-Sm(III) and herring sperm DNA. By combination analysis of the Scatchard method, circular dichroism spectroscopy and viscosity method, it suggests that the interaction mode between MB-Sm(III) complex and herring sperm DNA are a mixed binding, which contains partial intercalation and electrostatic interaction
SYNTHESIS AND DNA INTERACTION OF A Sm(III) COMPLEX OF A SCHIFF BASE DERIVED FROM VANILLIN AND L-TRYPTOPHAN
No full textThe interaction between the Sm(III) complex of an ionic Schiff base [HL](-), derived from vanillin and L-tryptophan, and herring sperm DNA at physiological pH (7.40) has been studied by UV-Vis absorption, fluorescence and viscosity methods. The binding ratios nSm(III) : nK[HL] = 1: 1 and nSm(III) L : nDNA = 5: 1 were confirmed by a mole ratio method. The calculated binding constants of [Sm(III)L](+) with DNA at 25 and 37 C were 1.19 x 10(5) M-1 and 3.96 x 10(4) M-1, respectively. The thermodynamic parameters demonstrate that the interaction between [Sm(III) L](+) and DNA is driven mainly by enthalpy. Fluorimetric studies show that [Sm(III) L](+) is able to displace intercalated acridine orange. Combined with Scatchard methods, circular dichroism spectroscopy and viscosity measurements, the results indicate that the interaction between [Sm(III) L](+) and herring sperm DNA is mainly by intercalation with some groove binding
Direct EELS observation of the oxidation states of Sm atoms in Sm@C-2n metallofullerenes (74 <= 2n <= 84)
Full text linkThe oxidation states of Sm atoms in various fullerene cages are directly investigated by electron energy-loss spectroscopy. The observed peak positions of the M-45 edges of the Sm atom in Sm@C-2n, [2n = 74, 78, 80, 82 (isomers I, III), 84, (isomers I, II, III)] are apparently shifted to the lower binding energy region in comparison with those of a trivalent Sm3+ in Sm2O3. The results indicate that the Sm atoms take 12 valence states irrespective of the fullerene cages. This observation is discussed based on a simple thermochemical cycle model. We also report that the Sm metallofullerenes have been converted to Sm carbide materials under a prolonged electron beam irradiation. (C) 2000 American Institute of Physics.

beta-decay spectroscopy of neutron-rich Sm-160,Sm-161,Sm-162 isotopes
Full text linkNeutron-rich Sm-160,Sm-161,Sm-162 isotopes have been populated at the RIBF, RIKEN via beta decay for the first time. beta-coincident gamma rays were observed in all three isotopes including gamma rays from the isomeric decay of Sm-160 and Sm-162. The isomers in Sm-160 and Sm-162 have previously been observed but have been populated via beta decay for the first time. The isomeric state in Sm-162 is assigned a 4(-) nu 7/2(+)[633]circle times nu 1/2(-)[521] configuration based on the decay pattern. The level schemes of Sm-160 and Sm-162 are presented. The ground states in the parent nuclei Pm-160 and Pm-162 are both assigned a 6(-) nu 7/2(+)[633]circle times pi 5/2(-)[532] configuration based on the population of states in the daughter nuclei. Blocked BCS calculations were performed to further investigate the spin-parities of the ground states in Pm-160, Pm-161, and Pm-162, and the isomeric state in Sm-162.CPCI-S(ISTP)[email protected]
Parallelizations on products of spheres and octonionic geometry
No full textA classical theoremof Kervaire states that products of spheres are parallelizable if and only if at least one of the factors has odd dimension. Two explicit parallelizations on Sm × S2h−1 seem to be quite natural, and have been previously studied by the first named author in [32]. The present paper is devoted to the three choices G = G2, Spin(7), Spin(9) of G-structures on Sm × S2h−1, respectively with m + 2h − 1 = 7, 8, 16 and related with octonionic geometry
Turnitin Religious Syncretism As A New Model For Interreligious Harmony: A Study Of Tridharma In Indonesia
Full text linkSix-proposition manifesto for small Island territories
Full text linkConventional wisdom suggests that small, often island, states are more likely than larger nations to be hard hit by the effects of national disasters, of fluctuations in the global economy, and the political aspirations of world powers. The structural weaknesses they share have been quantified to create a Vulnerability Index. This paper points to what the author sees as flaws in the concept of vulnerability and its application to the weaknesses of small states. In particular he presents evidence that small developing countries have performed no worse than larger countries. He sets out six propositions which explain this paradox and identifies the comparative advantages that small states hold.peer-reviewe
