INTERTEXTUALITY IN INDONESIAN NEWSPAPER OPINION ARTICLES ON EDUCATION: ITS TYPES, FUNCTIONS, AND DISCURSIVE PRACTICE

This research deals with intertextuality in opinion articles on education. Its objectives are to discover types and functions of intertextuality in the articles and to reveal its social practice. The results of the research reveal there are three major types and two major functions of intertextuality in the articles. The type dominantly ap-plied is indirect quotation and the function dominantly applied is to provide things in detail. The social practice found in the articles is that the intertextuality is functioned to create an image that the articles possess a level of academic text. Key words: intertextuality, discursive practice, discourse, newspaper, opi-nion articl

Analytical approximation for the sphere-sphere Coulomb potential

A simple analytical expression, which closely approximates the Coulomb potential between two uniformly charged spheres, is presented. This expression can be used in the optical potential semiclassical analyses which require that the interaction be analytic on and near the real r-axis.Comment: 4 pages including 3 figures and 1 tabl

Santon Dari Kulit Batang Tumbuhan Asam Kandis (Garcinitz Cowa)

The genus Garcinia is known to be a rich source of oxygenated xanthone, prenylated xanthone, and polyisoprenylated benzophenones. Some of them exhibiting various biological activities such as antimycrobachterial,antioxidant, cytotoxic, and antimalaria activities. Garcinia cowa belonging to the Guttiferaefamily, in Indonesia this plant is locally named asamkandis In our continuing phytochemical investigation of Garcinia plants is found in Indonesia a xanthone cowanine compound has been isolated from the steam bark of Garctnia cowa. The structure of this compound has been determined base on spectroscopic data including uv, lR,J-D NMR, and these are comparedwith the literaturedata

Increased Expression of Autophagy-Related Genes in Alzheimer’s Disease—Type 2 Diabetes Mellitus Comorbidity Models in Cells

The association between Alzheimer’s disease (AD) and type 2 diabetes mellitus (T2DM) has been extensively demonstrated, but despite this, the pathophysiological mechanisms underlying it are still unknown. In previous work, we discovered a central role for the autophagy pathway in the common alterations observed between AD and T2DM. In this study, we further investigate the role of genes belonging to this pathway, measuring their mRNA expression and protein levels in 3xTg-AD transgenic mice, an animal model of AD. Moreover, primary mouse cortical neurons derived from this model and the human H4Swe cell line were used as cellular models of insulin resistance in AD brains. Hippocampal mRNA expression showed significantly different levels for Atg16L1, Atg16L2, GabarapL1, GabarapL2, and Sqstm1 genes at different ages of 3xTg-AD mice. Significantly elevated expression of Atg16L1, Atg16L2, and GabarapL1 was also observed in H4Swe cell cultures, in the presence of insulin resistance. Gene expression analysis confirmed that Atg16L1 was significantly increased in cultures from transgenic mice when insulin resistance was induced. Taken together, these results emphasise the association of the autophagy pathway in AD-T2DM co-morbidity, providing new evidence about the pathophysiology of both diseases and their mutual interaction

Morphological Characteristics of the Stomach of the Swamp Buffalo (Bubalus Bubalis)

The ability of swamp buffaloes for adaptation to swampland was suggested to be supported by their digestive system efficiency including absorption one. This research was done to obtain scientific explanation about digestive efficiency of swamp buffalo by investigating swamp buffalo stomach morphologically. Six stomachs were obtained at slaughterhouse from 2.5-3 years old healthy male swamp buffaloes. Every part of the stomach includes nonglanduler stomach (forestomach: rumen, reticulum, and omasum) and glanduler stomach (abomasum) was taken for measuring length, width, and weight organs. Then all of samples from each part of stomach were prepared for morphological observation. The data were analyzed descriptively. Stomach of swamp buffalo had morphological peculiarities, such as: mucosa surface of rumen, reticulum, and omasum has black color, and there is variation of ruminal papillae of swamp buffalo, including branching. Special characteristics of swamp buffalo stomach is estimated as supporting morphological factors for increasing digestive efficiency to survive in swampland

Bimbingan Kesulitan Belajar Berbasis Self Regulating Learning Dalam Meningkatkan Prestasi Belajar Siswa

: Self-regulated Learning as a Learning Guidance Model to Improve Learning Achievement. This study aims at developing a guidance model to deal with students\u27 learning problems and examining the effectiveness of its implementation. The development of self-regulated learning as the learning model involved senior high school students, advisory teachers, subject-matter teachers, and the headmaster. This learning model is geared toward encouraging the students to utilize self-regulated learning. This model appeared to be able to improve the students\u27 learning achievement

Temperature dependence of the photoluminescence properties of colloidal Cd Se ∕ Zn S core/shell quantum dots embedded in a polystyrene matrix

We report on the temperature dependence of the photoluminescence (PL) spectrum and of the PL relaxation dynamics for colloidal $\mathrm{Cd}\mathrm{Se}∕\mathrm{Zn}\mathrm{S}$ core/shell quantum dots (QDs) embedded in an inert polystyrene matrix. We demonstrate that the confinement energy in the QDs is independent of the temperature. The coupling with both acoustic and optical phonons is also studied. Quantum confinement results in a strong increase of the exciton\char21{}acoustic-phonon coupling constant, up to 71\phantom{\rule{0.3em}{0ex}}\ensuremath{\mu}\mathrm{eV}∕\mathrm{K}, and in a reduced exciton\char21{}longitudinal-optical (LO)-phonon coupling constant, down to $21\phantom{\rule{0.3em}{0ex}}\mathrm{meV}$, with respect to bulk CdSe. In addition, we demonstrate that the main nonradiative process that limits the quantum efficiency of the QD at room temperature is the thermal escape from the dot assisted by scattering with four LO phonons. Thermally activated trapping in surface states is also observed at low temperature, with an activation energy of about $15\phantom{\rule{0.3em}{0ex}}\mathrm{meV}$

Challenges on Missing Packet Detection or Packet Dropping Attacks in Mobile Adhoc Network -A Survey

Collection of wireless nodes forms together to communicate each other in the network without infrastructure less and any access point along with the characteristics of freedom in mobility is called Mobile Adhoc Network. Transmitting of packets from source to destination plays the vital role in MANET. When a Packet is not delivered properly at the destination , its affects the performance of the MANET.  Due to this characteristics of the mobility nodes can subject to falls on the packet missing also the various packets dropping security attacks take part in the dropping the packets while communication to achieve the decreasing the performance of the MANET. This article focus on the survey about the missing packet assembly as well the packet dropping security attacks in MANET
