Non-minimal Einstein-Yang-Mills-Higgs theory: Associated, color and color-acoustic metrics for the Wu-Yang monopole model

We discuss a non-minimal Einstein-Yang-Mills-Higgs model with uniaxial anisotropy in the group space associated with the Higgs field. We apply this theory to the problem of propagation of color and color-acoustic waves in the gravitational background related to the non-minimal regular Wu-Yang monopole.Comment: 14 pages, no figure

Hutan Diklat Sisimeni Sanam merupakan suatu areal hutan yang diperuntukan sebagai sarana dan prasarana praktek dalam rangka mendukung kegiatan diklat kehutanan serta sebagai laboratorium alam untuk mengembangkan ilmu pengetahun dan teknologi (Iptek) di bidang kehutanan. Kawasan Hutan Diklat Sisimeni sanam (RTK.185) Pulau Timor secara keseluruhan telah disahkan sebagai kawasan hutan tetap pada tanggal 25 September 1982 oleh MenteriPertanian u.b. Direktur Jendral Kehutanan dengan fungsi sebagai hutan produksi terbatas, sehingga kawasan hutan tersebut telah mempunyai kekuatan hukum. Dalam Permenhut No. 44 tahun 2012, tentang pengukuhan kawasan hutan dilakukan melalui tahapan penunjukan kawasan hutan, penataan batas kawasan hutan serta penetapan kawasan hutan. Kawasan Hutan Dengan Tujuan Khusus (KHDTK) Diklat Sisimeni sanam telah ditetapkan melalui Keputusan MenteriKehutanan No. SK. 367/Menhut-II/2009 dengan luas ± 2.973,20 ha dan panjang 37,94 km. Sebelum ditunjuk sebagai kawasan hutan pendidikan dan pelatihan berstatus sebagai Register Tanah Kehutanan (RTK) 185 kelompok hutan Sisimeni Sanam, dikelola sebagai Hutan Produksi oleh RPH Camplong, BKPH Camplong, CDK Kupang. Kurangnya sosialisasi dan komunikasi dari pihak pengelola dengan masyarakat Desa Sillu, mengakibatkan kurangnya pemahaman danwawasan masyarakat tentang Keberadaan Hutan Diklat Sisimeni Sanam. Tujuan dari penelitian ini adalah untuk mengetahui sikap, persepsi, perilaku mayarakat lokal terhadap keberadaan Hutan Diklat Sisimeni Sanam dan untuk mengetahui bagaimana partisipasi masyarakat dalam pengelolaan Hutan Diklat Sisimeni Sanam. Sampel yang digunakan dalam penelitian ini adalah penduduk sekitar kawasan Hutan Diklat Sisimeni Sanam yang berjumlah 91 jiwa, dengan penentuannya menggunakan purposive sampling. Hasil dari penelitian ini menunjukan bahwa sikap dan partisipasi masyarakat terhadap Hutan Diklat Sisimeni Sanam di Desa Sillu, Kecamatan Fatuleu, Kabupaten Kupang, Provinsi Nusa Tenggara Timur tergolong pada kategori baik (60.93% dan 79,08%), sedangkan tingkat persepsi dan perilaku mayarakat lokal terhadap keberadaan Hutan Diklat Sisimeni Sanam tergolong pada kategori netral (50,92% dan 52,59%)

Light Rays at Optical Black Holes in Moving Media

Light experiences a non-uniformly moving medium as an effective gravitational field, endowed with an effective metric tensor $\tilde{g}^{\mu \nu}=\eta^{\mu \nu}+(n^2-1)u^\mu u^\nu$, $n$ being the refractive index and $u^\mu$ the four-velocity of the medium. Leonhardt and Piwnicki [Phys. Rev. A {\bf 60}, 4301 (1999)] argued that a flowing dielectric fluid of this kind can be used to generate an 'optical black hole'. In the Leonhardt-Piwnicki model, only a vortex flow was considered. It was later pointed out by Visser [Phys. Rev. Lett. {\bf 85}, 5252 (2000)] that in order to form a proper optical black hole containing an event horizon, it becomes necessary to add an inward radial velocity component to the vortex flow. In the present paper we undertake this task: we consider a full spiral flow, consisting of a vortex component plus a radially infalling component. Light propagates in such a dielectric medium in a way similar to that occurring around a rotating black hole. We calculate, and show graphically, the effective potential versus the radial distance from the vortex singularity, and show that the spiral flow can always capture light in both a positive, and a negative, inverse impact parameter interval. The existence of a genuine event horizon is found to depend on the strength of the radial flow, relative to the strength of the azimuthal flow. A limitation of our fluid model is that it is nondispersive.Comment: 30 pages, LaTeX, 4 ps figures. Expanded discussion especially in section 6; 5 new references. Version to appear in Phys. Rev.

Efektivitas Pemanfaatan Limbah Tahu Cair Melalui Metode Frekuensi Waktu Penyiraman terhadap Pertumbuhan Produksi Rumput Gajah (Pennisetum purpureum)

This research was conducted in the experimental garden of the Faculty of Agriculture, University of Timor, Sasi, North Central Timor Regency. The research will last for 1 production period (45 HST), from the end of March to the beginning of June 2019. The purpose of this study is to analyze the value of growth and production of Pennisetum purpureum treated with frequency of time watering liquid tofu waste. This research is an experimental study using a randomized design Complete (CRD) consisting of 4 treatments and 4 replications so that there are 16 units of the experimental unit. The treatments tested consisted of: R0 = Without watering tofu waste, R1 = Frequency of watering once every 2 days, R2 = Frequency of watering once every 4 days, R3 = Frequency of watering once every 6 days. The variables observed in this study were plant height, stem diameter, leaf fresh weight and leaf dry weight. The results showed that giving treatment of the frequency of time of watering the liquid tofu waste, had a significant effect on the fresh weight of leaves produced but did not differ on plant height of stem diameter and dry weight produced. It could be concluded that liquid tofu waste with good watering time frequency was found in the treatment R1 which is 2 days, liquid tofu waste has the ability to improve soil texture and can stimulate the growth of Pennisetum purpureum in this case the growth of plant height, stem diameter, leaf fresh weight, and leaf dry weight.Penelitian ini dilaksanakan di kebun percobaan Fakultas Pertanian, Universitas Timor, Kelurahan Sasi, Kecamatan Kota, Kabupaten Timor Tengah Utara.

On the inertia of heat

Does heat have inertia? This question is at the core of a long-standing controversy on Eckart's dissipative relativistic hydrodynamics. Here I show that the troublesome inertial term in Eckart's heat flux arises only if one insists on defining thermal diffusivity as a spacetime constant. I argue that this is the most natural definition, and that all confusion disappears if one considers instead the space-dependent comoving diffusivity, in line with the fact that, in the presence of gravity, space is an inhomogeneous medium.Comment: 3 page

First Penning-trap mass measurement in the millisecond half-life range: the exotic halo nucleus 11Li

In this letter, we report a new mass for $^{11}$Li using the trapping experiment TITAN at TRIUMF's ISAC facility. This is by far the shortest-lived nuclide, $t_{1/2} = 8.8 \rm{ms}$, for which a mass measurement has ever been performed with a Penning trap. Combined with our mass measurements of $^{8,9}$Li we derive a new two-neutron separation energy of 369.15(65) keV: a factor of seven more precise than the best previous value. This new value is a critical ingredient for the determination of the halo charge radius from isotope-shift measurements. We also report results from state-of-the-art atomic-physics calculations using the new mass and extract a new charge radius for $^{11}$Li. This result is a remarkable confluence of nuclear and atomic physics.Comment: Formatted for submission to PR
