How the minuscule can contribute to the big picture: the neutron electric dipole moment project at TRIUMF

A permanent electric dipole moment (EDM) of a fundamental particle violates both parity (P) and time (T) reversal symmetry and combined charge and parity (CP) reversal symmetry if the combined reversal of charge, parity \textit{and} time (CPT) is preserved. It is a very promising place to search for physics beyond the Standard Model. Ultracold neutrons (UCN) are the ideal tool to study the neutron electric dipole moment since they can be observed for hundreds of seconds. This article summarizes the current searches for the neutron EDM using UCN and introduces the project to measure the neutron electric dipole moment at TRIUMF using its unique accelerator driven spallation neutron and liquid helium UCN source. The aim is to reach a sensitivity for the neutron EDM of around $10^{-27} \,e \cdot$cm.Comment: 12 pages, 6 figures, MENU 2016 Conference, Kyoto, Japa

Preparation of linear hydroxy substituted polyphosphazenes

The synthesis of partially hydroxy-substituted phosphazene prepolymers amenable to processing into cellular, flexible polyurethane foams was investigated. Factors determined include (1) the environment of the hydroxyl group; (2) the ease of the hexachlorocyclotriphosphazene polymerization; (3) the nature of the nonreactive substituents; and (4) the mode of introduction of the hydroxyl entity. The specific approaches taken, the rationale of the selections made, and the results are discussed

The NJL-jet model for quark fragmentation functions

A description of fragmentation functions which satisfy the momentum and isospin sum rules is presented in an effective quark theory. Concentrating on the pion fragmentation function, we first explain why the elementary (lowest order) fragmentation process q --> q \pi is completely inadequate to describe the empirical data, although the "crossed" process \pi --> q \bar{q} describes the quark distribution functions in the pion reasonably well. Taking into account cascade-like processes in a generalized jet-model approach, we then show that the momentum and isospin sum rules can be satisfied naturally, without the introduction of ad hoc parameters. We present results for the Nambu--Jona-Lasinio (NJL) model in the invariant mass regularization scheme and compare them with the empirical parametrizations. We argue that the NJL-jet model, developed herein, provides a useful framework with which to calculate the fragmentation functions in an effective chiral quark theory.Comment: 21 pages, 7 figure

The structure and possible origins of stacking faults in gamma-yttrium disilicate

Parallel stacking faults on (010) planes are frequently observed in hot-pressed Y2Si2O7. A combination of conventional dark-field imaging and high-resolution transmission electron microscopy was used to investigate the structure of these faults and it was found that they consist of the repeat of one layer of the two layer γ-Y2Si2O7 structure with an associated in-plane rigid body displacement. The resulting structure was confirmed by image simulation of high-resolution images from two perpendicular projections. A model for the formation of the stacking faults is proposed as a consequence of a transformation from β-Y2Si2O7 to γ-Y2Si2O7 in the hot pressing

Preparation of perfluorinated 1,2,4-oxadiazoles

Fluorinated alkyl or alkylether 1,2,4 oxadiazole compounds are prepared by cyclizing the corresponding alkyl or alkylether imidoyl amidoximes in vacuo or in an inert atmosphere at a temperature within the range of 40 C to 100 C. for a period of 8 to 144 hours in the presence of an acid compound which can accept ammonia to form a salt. The imidoyl amidoximes usable in this process are either polymeric or nonpolymeric. The products, when polymeric, have excellent heat, chemical and solvent resistance

Efek Membangun Pendidikan Karakter di Lingkungan Perguruan Tinggi: Strategi, Budaya, dan Kinerja

Institusi pendidikan tinggi sebagai salah satu wahana dan media yang dapat dijadikan sebagai strategi pembangunan dan pengembangan pendidikan karakter bagi mahasiswa, agar menjadi mahasiswa yang memiliki etika dan moral akademik dan menjunjung tinggi nilai-nilai luhur pancasila. Upaya yang dapat dilakukan institusi pendidikan tinggi dengan cara mengintegrasikan pendidikan karakter ke dalam mata kuliah. Pengintegrasian pendidikan karakter sebagaimana dimaksud mulai dari penyusunan profil dan capaian pembelajaran, pelaksanaan pembelajaran dan sampai tahapan evaluasi hasil belajar yang memberikan kesimbangan pada tiga domain pendidikan yaitu kognitif, afektif dan psikomotorik. Selain mengintegrasiakan pendidikan karakter pada mata kuliah, dosen sebagai pengendali pembelajaran dapat melakukan dengan memberikan keteladan nilai karakter akademik dalam bentuk sikap dan perilaku disiplin dalam menegakkan norma, kritis dan kreatif dalam bentindak, rasional dalam berpikir, jujur dalam tutur kata, bertanggung jawab dalam mengemban kewajiban serta sikap anti plagiat dalam penyelesaian karya ilmiah. Bagaimana pembentukan karakter mahasiswa yang beretika dan bermoral akademis. Bagaimana proses integrasi pendidikan karakter melalui kegiatan ekstra mahasiswa yang dilaksanakan di luar kelas. Apa tindakan best practice institusi untuk menjalankan program integratif didalam kampus dengan luar kampus. Penelitian ini menggunakan metode fenomenologi. Tujuan penelian ini memberikan konsep dan strategi tentang pengembangan pendidikan karakter pada institusi pendidikan tinggi, dan diharapkan memberikan manfaat kepada pelaksana akademik dalam mendesain pendidikan karakter bagi mahasiswa
