Berdasarkan hasil penelitian menunjukan bahwa ekstrak buah mahkota dewa (Phaleria macrocarpa) dan ekstrak buah kurma (Phoenix dactylifera) memiliki efektivitas sebagai nefroprotektor dengan buah mahkota dewa lebih efektif dibandingkan dengan buah kurma

Identifikasi dan Penetapan Kadar Rhodamin B dalam Kerupuk Berwarna Merah yang Beredar di Masyarakat

Kerupuk  merupakan  makanan  ringan  yang  dibuat  dari  adonan  tepung tapioka dicampur bahan perasa.Kerupuk tidak lepas dari masalah keamanan makanan jajanan. Adanya produsen yang menggunakan Rhodamin B pada produknya. Rhodamin B merupakan zat warna sintetis yang umumnya digunakan sebagai zat warna kertas, tekstil atau tinta.Tujuan dari penelitian ini adalah untuk melakukan uji analisa kuantitatif terhadap Rhodamin B yang terdapat pada kerupuk merah  dengan  menggunakan  Spektrofotometri  Uv-Visibel.Penelitian  yang digunakan adalah penelitian eksperimental. Populasi penelitian ini adalah seluruh kerupuk berwarna merah yang beredar di pasar tradisional dan pasar modern Kota Medan. Dengan mengambil 5 sampel dari masing-masing pasar tradisional dan pasar modern Kota Medan. Dari penelitian ini didapatkan 7 sampel kerupuk teridentifikasi mengandung Rhodamin  B  dan  3  sampel  kerupuk  lainnya  tidak  mengandung  Rhodamin  B. Dengan  sampel  kerupuk  dari  pasar  modern  tidak  terdapat  kadar  Rhodamin  B, hanya dua (2) sampel yaitu A3 dan A4 yang memiliki kadar Rhodamin B yang sangat sedikit yaitu 0,01. Dan sampel kerupuk dari pasar tradisional terdapat kadar Rhodamin B yang cukup beragam mulai dari 1,14 PPM (B1), 1,39 (B2), 1,63 PPM (B3), 2,06 PPM (B5), dan 2,53 PPM (B2).Rata-rata kandungan Rhodamin B pada sampel  kerupuk  dari  pasar  tradisional  adalah  1,75  PPM.  Sedangkan  rata -rata kandungan sampel kerupuk dari pasar modern adalah 0,004 PPM. Berdasarkan uji statistika dengan Mann-Whitney Test, didapati nilai P adalah 0,008 yang artinya terdapat perbedaan rata-rata kadar Rhodamin B antar sampel kerupuk dari pasar tradisional dan modern yang secara statistik bermakna. Perlu dilakukannya penelitian untuk menemukan inovasi dalam identifikasi Rhodamin B pada sampel kerupuk yang lebih praktis, cepat, dan murah sehingga lebih aplikatif bagi masyarakat

Phase ordering and shape deformation of two-phase membranes

Within a coupled-field Ginzburg-Landau model we study analytically phase separation and accompanying shape deformation on a two-phase elastic membrane in simple geometries such as cylinders, spheres and tori. Using an exact periodic domain wall solution we solve for the shape and phase ordering field, and estimate the degree of deformation of the membrane. The results are pertinent to a preferential phase separation in regions of differing curvature on a variety of vesicles.Comment: 4 pages, submitted to PR

Generic, network schema agnostic sparse tensor factorization for single-pass clustering of heterogeneous information networks

Heterogeneous information networks (e.g. bibliographic networks and social media networks) that consist of multiple interconnected objects are ubiquitous. Clustering analysis is an effective method to understand the semantic information and interpretable structure of the heterogeneous information networks, and it has attracted the attention of many researchers in recent years. However, most studies assume that heterogeneous information networks usually follow some simple schemas, such as bi-typed networks or star network schema, and they can only cluster one type of object in the network each time. In this paper, a novel clustering framework is proposed based on sparse tensor factorization for heterogeneous information networks, which can cluster multiple types of objects simultaneously in a single pass without any network schema information. The types of objects and the relations between them in the heterogeneous information networks are modeled as a sparse tensor. The clustering issue is modeled as an optimization problem, which is similar to the well-known Tucker decomposition. Then, an Alternating Least Squares (ALS) algorithm and a feasible initialization method are proposed to solve the optimization problem. Based on the tensor factorization, we simultaneously partition different types of objects into different clusters. The experimental results on both synthetic and real-world datasets have demonstrated that our proposed clustering framework, STFClus, can model heterogeneous information networks efficiently and can outperform state-of-the-art clustering algorithms as a generally applicable single-pass clustering method for heterogeneous network which is network schema agnostic

300 Area Treatability Test: Laboratory Development of Polyphosphate Remediation Technology for In Situ Treatment of Uranium Contamination in the Vadose Zone and Capillary Fringe

This report presents results from bench-scale treatability studies conducted under site-specific conditions to optimize the polyphosphate amendment for implementation of a field-scale technology demonstration to stabilize uranium within the 300 Area vadose and smear zones of the Hanford Site. The general treatability testing approach consisted of conducting studies with site sediment and under site conditions, to develop an effective chemical formulation and infiltration approach for the polyphosphate amendment under site conditions. Laboratory-scale dynamic column tests were used to 1) quantify the retardation of polyphosphate and its degradation products as a function of water content, 2) determine the rate of polyphosphate degradation under unsaturated conditions, 3) develop an understanding of the mechanism of autunite formation via the reaction of solid phase calcite-bound uranium and aqueous polyphosphate remediation technology, 4) develop an understanding of the transformation mechanism, the identity of secondary phases, and the kinetics of the reaction between uranyl-carbonate and -silicate minerals with the polyphosphate remedy under solubility-limiting conditions, and 5) quantify the extent and rate of uranium released and immobilized based on the infiltration rate of the polyphosphate remedy and the effect of and periodic wet-dry cycling on the efficacy of polyphosphate remediation for uranium in the vadose zone and smear zone

Relationships between anopheline mosquitoes and topography in West Timor and Java, Indonesia

<p>Abstract</p> <p>Background</p> <p>Malaria is a serious health issue in Indonesia. Mosquito control is one aspect of an integrated malaria management programme. To focus resources on priority areas, information is needed about the vectors and their habitats. This research aimed to identify the relationship between anopheline mosquitoes and topography in West Timor and Java.</p> <p>Methods</p> <p>Study areas were selected in three topographic types in West Timor and Java. These were: coastal plain, hilly (rice field) and highland. Adult mosquitoes were captured landing on humans identified to species level and counted.</p> <p>Results</p> <p>Eleven species were recorded, four of which were significant for malaria transmission: <it>Anopheles aconitus, Anopheles barbirostris, Anopheles subpictus </it>and <it>Anopheles sundaicus</it>. Each species occupied different topographies, but only five were significantly associated: <it>Anopheles annularis, Anopheles vagus </it>and <it>Anopheles subpictus </it>(Java only) with hilly rice fields; <it>Anopheles barbirostris, Anopheles maculatus </it>and <it>Anopheles subpictus </it>(West Timor only) with coastal areas.</p> <p>Conclusion</p> <p>Information on significant malaria vectors associated with specific topography is useful for planning the mosquito control aspect of malaria management.</p
