Exact Static Cylindrical Solution to Conformal Weyl Gravity
We present the exact exterior solution for a static and neutral cylindrically
symmetric source in locally conformal invariant Weyl gravity. As a special case
the general relativity analogue still can be attained, however only as a
sub-family of solutions. Our solution contains a linear term that would thus
result in a potential that grows linearly over large distances. This may have
implications for exotic astrophysical structures as well as matter fields on
the extremely small scale.Comment: 8 pages, Physical Review
Analisis Dampak Lalu Lintas di Kawasan Singkawang Grand Mall pada Saat 48% Beroperasi
The construction of the Singkawang Grand Mall will impact traffic around Singkawang area Grand Mall (Jalan tani, Jalan Kesatriaan, Jalan alianyang). Changes and intensity of land use activities will certainly bring increased traffic volume. Land use change when not in anticipation of it well can lead to problems in the operation of the Singkawang Grand Mall. A problem that caused IE not the share of road capacity with volume road after 100% operational Singkawang Grand Mall. This research aims to know the magnitude of the force generation and dirimbulkan by the Singkawang Grand Mall, to know the capacity of the Farm Road, kesatriaan Road, and the road Alianyang before and after operation of Singkawang Grand Mall in the study take sampling data Singakwang grand Mall at present operates 48% of the test results of the research are as follows: 1) farmer\u27s Road performance level before operating 100% acquired Grand Mall of Singkawang 0.325 or enter into A service level; 2) after operating 100% level of service in the way Farmers to 0.60 or into alternative b. service levels obtained from this research such as; menambahan Farm Road Width of 6 meters to 7 meters so that the level of service "Jalan Tani" back A
Cr doped III-V nitrides: potential candidates for spintronics
Studies of Cr-doped III-V nitrides, dilute magnetic alloys, in the
zinc-blende crystal structure are presented. The objective of the work is to
investigate half-metallicity in Al(0.75)Cr(0.25)N, Ga(0.75)Cr(0.25)N and
In(0.75)Cr(0.25)N for their possible application in the spin based electronic
devices. The calculated spin polarized band structures, electronic properties
and magnetic properties of these compounds reveal that Al0.75Cr0.25N and
Ga0.75Cr0.25N are half-metallic dilute magnetic semiconductors while
In0.75Cr0.25N is metallic in nature. The present theoretical predictions
provide evidence that some Cr doped III-V nitrides can be used in spintronics
devices
Strategi Partai Politik dalam Pemilihan Legislatif Tahun 2014 (Studi Kasus Pdi Perjuangan di Dapil II Kecamatan Rumbai dan Rumbai Pesisir Kota Pekanbaru)
This study on the legislative elections of 2014 ago, an increase of votes is very significant that experienced by the PDI-P in the City Pekanabru. This is seen in the comparison sounds PDI obtained in 2009 which won 11 551 votes, while in 2014 the PDI-P, said Monday that 30 374 voice sound. the author is trying to formulate questions such as "how the PDI-P strategy in recruiting legislative pemelihan pemillih in 2014 in Dapil II District Rumbai and Rumbai Coastal. The purpose of this study to mengetahuai strategy undertaken by the PDI-P in recruiting voters on the legislative elections 2014. On the results of research and discussion of trying to define all mutual researcher in two classifications at the level of analysis that is offensive strategy PDI Pekanbaru city, then the analysis is based on the strategy Defensive Indonesian Democratic Party struggle Pekanbaru. This research method approach this research uses qualitative that can be interpreted as the research that produced the data Descriptive, location research was conducted in the city of Pekanbaru precisely at the Council Office Pimpingan Branch Party PDI Pekanbaru, tekni pengumpula data in this study are: Interviews then Documentation after data writers get, for data analysis techniques, as follows: Presentation of Data Reduction the data is then include various types namely matarik, tables, and charts network. Based on the research and the strategies used Branch Council party PDI-P Pekanbaru in increasing the vote on the legislative elections of 2014 the city of Pekanbaru do Retkrutmen is open for prospective Legislature, then the Son Branch PDI help celeg to socialize under pantawan Board PDI Branch Pimpimnan struggle Pekanbaru
Excitonic quasiparticles in a spin-orbit Mott insulator
In condensed matter systems, out of a large number of interacting degrees of
freedom emerge weakly coupled particles, in terms of which most physical
properties are described. For example, Landau quasiparticles (QP) determine all
electronic properties of a normal metal. The lack of identification of such QPs
is major barrier for understanding myriad exotic properties of correlated
electrons, such as unconventional superconductivity and non-Fermi liquid
behaviours. Here, we report the observation of a composite particle in a Mott
insulator Sr2IrO4---and exciton dressed with magnons---that propagates with the
canonical characteristics of a QP: a finite QP residue and a lifetime longer
than the hopping time scale. The dynamics of this charge-neutral bosonic
excitation mirrors the fundamental process of the analogous one-hole
propagation in the background of ordered spins, for which a well-defined QP has
never been observed. The much narrower linewidth of the exciton reveals the
same intrinsic dynamics that is obscured for the hole and is intimately related
to the mechanism of high temperature superconductivity.Comment: submitted versio
Pengembangan Bahan Ajar Kimia Larutan Pada Semester 2 Jurusan Pmipa Fkip Unbari Jambi
Development of teaching materials Chemical solution with contextual learning for FKIP UNBARI Jambi PMIPA department is based on the fact the unavailability of teaching materials especially those that have spesipikasi with contextual learning. This development aims to produce teaching materials Chemical solution with contextual learning for PMIPA department FKIP UNBARI Jambi as grip material faculty and students. Where the research performed at the Department of Guidance and Counseling PMIPA UNBARI Jambi. Product validation teaching materials in this study is a matter experts and instructional media experts, field trials .uji student groups. Teaching materials development activities carried out four (4) phases, (1) the preliminary stage, (2) the stage of development, (3) the stage of preparation of teaching materials products, (4) the stage of expert validation and testing stage products of small groups and large groups. Results of expert validation and expert validation meteri media only give suggestions for the improvement of teaching materials chemical solution. Teaching materials that have been tested in this final group of small and large groups. Results of testing the effectiveness of teaching materials components were analyzed using percentages show good results with an average value of 85.32% dan79,19%. Based on trial results, we can conclude that the solution chemistry teaching materials developed can be used in basic chemistry lectures on the subject of chemical solution
