Measuring the muon's anomalous magnetic moment to 0.14 ppm

The anomalous magnetic moment (g-2) of the muon was measured with a precision of 0.54 ppm in Experiment 821 at Brookhaven National Laboratory. A difference of 3.2 standard deviations between this experimental value and the prediction of the Standard Model has persisted since 2004; in spite of considerable experimental and theoretical effort, there is no consistent explanation for this difference. This comparison hints at physics beyond the Standard Model, but it also imposes strong constraints on those possibilities, which include supersymmetry and extra dimensions. The collaboration is preparing to relocate the experiment to Fermilab to continue towards a proposed precision of 0.14 ppm. This will require 20 times more recorded decays than in the previous measurement, with corresponding improvements in the systematic uncertainties. We describe the theoretical developments and the experimental upgrades that provide a compelling motivation for the new measurement.Comment: 5 pages, 1 figure, presented at International Nuclear Physics Conference 2010 (INPC 2010

JAARMARKT DI SURABAYA MASA PEMERINTAHAN HINDIA-BELANDA

Pada awal abad ke-20, Surabaya telah berkembang menjadi kota modern di mana pengembangan pusat industri dan komersial. Kemajuan  ini tidak  terlepas  dari arah  politik negara yang  dikelola Etis Hindia  Belanda tahun 1900-an ditandai  dengan  kemajuan  dalam  berbagai  sektor  kehidupan.  Seiring  dengan  pesatnya  pertumbuhan  industri  dan meningkatnya  jumlah  penduduk  yang  hidup  di  Eropa  Surabaya, pemerintah  Hindia  Belanda  menyediakan  fasilitas untuk  menampilkan  hasil  industri  dan  menyediakan  sarana  promosi  bagi  perusahaan  yang  ingin  memperkenalkan produk mereka. Produksi pameran yang diselenggarakan pemerintah disebut Jaarmarkt. Jaarmarkt juga bertujuan untuk mencari  keuntungan  finansial melalui  media  pemerintah menunjukkan  pameran  yang  diadakan  setiap  tahun  sekali. Permasalahan  yang  diteliti dalam  penelitian  ini  adalah apa  latar  belakang Jaarmarkt pemerintah terorganisir Hindia Belanda.  Jenis  penelitian  dalam  penelitian  ini  adalah  studi  sejarah  dengan  menggunakan  metode  historis.  Metode sejarah  meliputi  tahap  heuristik,  kritik,  interpretasi,  dan  historiografi.  Hasil  akhir  dari  penelitian  ini  adalah  untuk memberikan  gambaran  informasi  mengenai  Jaarmarkt  alasan  mulai  dari  Hindia  Jaarmarkt  pemerintah  terorganisir Belanda,  produk  industri  dan  hiburan  yang  ditampilkan  dalam  Jaarmarkt,  serta  pengelolaan  Jaarmarkt  awal  berdiri diselenggarakan oleh pemerintah dengan manajemen birokrasi sendiri.  Kata Kunci: Jaarmarkt, Pemerintah Hindia-Belanda, Surabay

Determinação da aptidão para desportos de natureza em áreas classificadas com recurso à análise multicritério. A Orientação no Parque Natural do Tejo Internacional.

A crescente procura de territórios rurais para fins turístico-recreativos, com especial incidência nas áreas de valor paisagístico mais elevado, requer a necessidade de compatibilizar a fruição dessas áreas com a preservação e conservação dos valores naturais. Surge, assim, a necessidade de desenvolver uma metodologia de gestão do território apoiada em ferramentas de análise espacial multicritério. Para a determinação das áreas com potencial para a prática das atividades de recreio ativo, recorreu-se à pesquisa de informação, biofísica e socioeconómica, que permitiu a caracterização do território e da sua utilização por parte dos diferentes stakeholders. Por outro lado, foi analisada informação sobre as especificidades das diferentes modalidades de recreio ativo com o objetivo de identificar as condicionantes e potencialidades para a sua prática. A identificação das áreas com aptidão para o recreio, bem como das condicionantes, foi efetuada com base na integração de um conjunto de fatores com recurso ao programa ArcGIS. Os fatores foram classificados em três níveis de aptidão, calculados mediante a aplicação de um método de análise espacial multicritério - o Processo Analítico Hierárquico (AHP). Como resultado obteve-se um modelo de utilização turístico-recreativo do território em estudo numa perspetiva de apoio à sua gestão sustentável.info:eu-repo/semantics/publishedVersio

Pengaruh Emulgator Buah Lerak (Sapindus Rarak) dengan Emulsi Air dan Solar sebagai Bahan Bakar Motor Diesel Ramah Lingkungan

This research is aimed at finding out the effect of emulsion of water and diesel fuelwith lerak emulsifier on the gas emission of diesel fuel and its effect on the power producedby the diesel motor.The steps involved in the research are extracting lerak and blending the emulsion ofwater and diesel fuel by using lerak extract emulsifier. To test the sample of lerak extractmethods used were IKU/5.4/TK-02 for Viscosity Kinematic at 30°C, IKU/5.4/TK-03 for FlashPoint PM.CC, IKU/5.4/TK-04 for Pour Point, ASTM 130 for Copperstrip Corosion at 100°C, (3hrs),ASTM 473 for Sediment test, dan ASTM D 95 for Water Content.The reasearch result showed that the lerak extract was made successfully by usingethanol solvent. However, the process of blending the lerak emulsifier and water as well asdiesel fuel was not successful yet. They were not blended perfectly yet though the result ofthe blending process had shown the different contents of diesel fuel

Kekerasan Di Televisi: Perspektif Kultivasi

Indonesians are categorized as Views Society, i.e. society who significantly spent most of their leisure times in front of the screen, instead of doing other activities, such as reading. Television, on the other hand, proved to be an effective media whose outreach and penetration potent were undefeatable compared with other media. This situation turns to be problematic, due to the low quality of television which contained violence materials. People naturally learn violence from television. Being overexposed to violence materials, people were getting used to solve their problems by means of violence, too

Strategi Komunikasi Dinas Lingkungan Hidup (Dlh) dalam Mengimplementasikan Program Green City di Kota Teluk Kuantan Kabupaten Kuantan Singingi

Green city is a program issued by the Ministry of Environment and Forestry in 2007. This program is for local governments to implement environmentally sound development. Kuantan Singingi regency is one of the regencies that try to apply Green City concept, this program is coordinated by the Environment Agency (DLH). The purpose of this program is to realize Kuansing with the concept of Environment. This program involves many parties, namely the public, private parties, offices, and companies in Kuansing. Many implementations have been done to realize this green city, one of which is planting tree seeds on the protocol road. The purpose of this research is to know communicator strategy in implementing green city, audience strategy, message strategy and media USAge in implementing green city program.This research uses qualitative research method. Informant of this research is 5 people consisting of 2 people from Environmental Office of Kuantan regency singingi and 3 people of society which is chosen by purposive. Data collection techniques used are observation, interview, and documentation. Data validity technique used in this research is triangulation and extension of participation.The result of the research shows that the communicator strategy of Environmental Office is to involve people who are experts and experienced in environment such as Environmental Science Lecturer and Environmental Expert. In addition, it also involves people who have influence on the community such as Village Heads, Adat Stakeholders and Religious Leaders. Strategy Determination of the audience by the Office of the Environment is to choose the nearest audience from downtown, the city of Kuantan Bay and surrounding areas.
