Scalar Sector in the Minimal Supersymmetric 3-3-1 model

We consider the minimal supersymmetric extension of the 3-3-1 model and we study the mass spectra in the scalar sector of this model without the anti-sextet. We show that all our lighest scalars are in agreement with the experimental limits.Comment: It was included on the introduction of the article the motivation to > study the model, and we moved the sections 4.1 and 4.2 to the appendix. It has 22 pages, 9 figures. It was accepted to be published at International Journal of Modern Physics

An on-line harmonics elimination PWM scheme for three-phase voltage source inverters

An on-line harmonic elimination PWM (HEPWM) scheme for three-phase voltage source inverters is proposed. It is based on curve fitting method derived from the trajectories of the exact (off-line) HEPWM angles. The main advantage of the technique is its fast and efficient realization using a microprocessor. An outline to obtain the switching angles is presented. The method is proven by experimental result

Role of the K1K_1 meson in K0K^0 photoproduction off the deuteron

Neutral kaon photoproduction off the nucleon and deuteron has been reinvestigated by utilizing the new experimental data on both targets. An isobar model for elementary operator and impulse approximation for the reaction on the deuteron have been used. The available free parameters in the elementary model have been extracted from both elementary and deuteron data. In contrast to the elementary reaction, fitting the deuteron data requires an inclusion of weighting factor. The result indicates that the angular distribution of the elementary $K^0\Lambda$ process does not show backward peaking behavior.Comment: 4 pages, 4 figures, prepared for the Fifth Asia-Pacific Conference on Few-Body Problems in Physics 2011 (APFB2011), Seoul, Korea, August 22-26, 201

Inhibitor(S) of prostaglandin endoperoxide synthase and lipoxygenase activity in extracts of barley

Aqueous extract of barley was found to inhibit PG endoperoxide synthase and lipoxygenase enzymes responsible for arachidonic acid metabolism. Only 6% (v/v) of aqueous extract produced 50% inhibition of PG endoperoxide synthase while five times more extract was required to produce 50% inhibition of lipoxygenase. Boiling barley extract did not destroy the ability of the extract to inhibit the enzymes. Fractionation of barley with organic solvents, petroleum ether, chloroform, ethylacetate and acetone exhibited selectivity in its action in that foamy layer formed during petroleum ether and ethyl acetate extraction inhibited PG endoperoxide synthase completely whereas lipoxygenase activity was only partially inhibited. These results suggest the presence of inhibitor(s) of arachidonic acid metabolism in extracts of barley

Spectrum of D=6, N=4b Supergravity on AdS_3 x S^3

The complete spectrum of D=6, N=4b supergravity with n tensor multiplets compactified on AdS_3 x S^3 is determined. The D=6 theory obtained from the K_3 compactification of Type IIB string requires that n=21, but we let n be arbitrary. The superalgebra that underlies the symmetry of the resulting supergravity theory in AdS_3 coupled to matter is SU(1,1|2)_L x SU(1,1|2)_R. The theory also has an unbroken global SO(4)_R x SO(n) symmetry inherited from D=6. The spectrum of states arranges itself into a tower of spin-2 supermultiplets, a tower of spin-1, SO(n) singlet supermultiplets, a tower of spin-1 supermultiplets in the vector representation of SO(n) and a special spin-1/2 supermultiplet also in the vector representation of SO(n). The SU(2)_L x SU(2)_R Yang-Mills states reside in the second level of the spin-2 tower and the lowest level of the spin-1, SO(n) singlet tower and the associated field theory exhibits interesting properties.Comment: 37 pages, latex, 5 tables and 3 figures, typos corrected, a reference adde

Analisis Perjanjian Kerjasama dan Pola Perbandingan Penyelesaian Sengketadi Luar Pengadilan

The contract or agreement is rapidly growing at this time as the consequence logical from the development cooperation business people business. Many business cooperation carried out by businessmen in the form of a contract or written agreement. The purpose of this research is to know and understand the legal analysis against the risks that arise in the agreement as well as to know the form of resolving disputes outside of the courts in the perspective of positive law and Islamic law. The type of research used in this study are normative legal research which in the use of research analysis Techniques used are qualitative techniques for which information unearthed through in-depth interviews and information search through the library, either from legislation, documents relating to the writing of this thesis so that what is in question in the study answered with a maximum. Results of the study showed that a cooperation agreement with Sejahtera Corporateand Adil Makmur potentially cause conflict so that it appears in the dispute between the parties resulting from any such agreement surfaced that there are risks such as risks language, the risk of disputes. To resolve this issue then there needs to be a model of dispute resolution that is ADR in particular using arbitration institutions while the Model dispute resolution outside of court according to ACT No. 30 of 1999 are mediation, arbitration, consilition, which chosen by the parties in accordance with applicable LAW while according to customary law, the dispute could be resolved through private, family, head of the indigenous organizational institution. &nbsp

Perspektif Politik Hukum terhadap Perlindungan dan Pembinaan Tenaga Kerja Luar Negeri di Indonesia

Pengiriman TKI ke luar negeri memang dapat memberikan manfaat ekonomi yang relatif besar tidak hanya bagi TKI itu sendiri dan keluarganya tetapi juga bagi negara tersebut, karena Negara tersebut menganggap pengiriman TKI ke luar negeri merupakan jawaban atas tidak adanya negara dalam menyediakan lapangan kerja. Penelitian yang digunakan dalam penelitian ini adalah dengan menggunajan jenis penelitian hukum normatif yang digunakan untuk menyusun penelitian. Review hasil penelitian menunjukkan bahwa Undang-Undang Hukum Politik Nomor 39 Tahun 2004 tentang perlindungan dan pembangunan Tenaga Kerja Indonesia di luar negeri ada 4 (empat) yaitu 1) Memberdayakan dan mendayagunakan tenaga kerja secara optimal dan manusia; 2) Menciptakan pemerataan peluang kerja dan penyediaan tenaga kerja sesuai dengan pembangunan nasional dan kebutuhan kabupaten; 3) memberikan perlindungan kepada pekerja dalam menciptakan kesejahteraan; dan 4) kesejahteraan buruh dan keluarganya sementara Faktor hukum politik implementasi hukum memengaruhi hukum Nomor 39 Tahun 2004 tentang perlindungan dan pembangunan Tenaga Kerja Indonesia di luar Negri terkait dengan perlindungan hukum di luar negeri memiliki TKI 2 (dua) yaitu 1) Struktur ( Ketenagakerjaan Dewan, b. Menjadi Keluhan minimal yang disediakan oleh Penguasa di luar negeri untuk TKI) dan 2) Substansi

Field Redefinition Invariance in Quantum Field Theory

The issue of field redefinition invariance of path integrals in quantum field theory is reexamined. A ``paradox'' is presented involving the reduction to an effective quantum-mechanical theory of a $(d+1)$-dimensional free scalar field in a Minkowskian spacetime with compactified spatial coordinates. The implementation of field redefinitions both before and after the reduction suggests that operator-ordering issues in quantum field theory should not be ignored.Comment: 7 page

The spread of the gluon k_t-distribution and the determination of the saturation scale at hadron colliders in resummed NLL BFKL

The transverse momentum distribution of soft hadrons and jets that accompany central hard-scattering production at hadron colliders is of great importance, since it has a direct bearing on the ability to separate new physics signals from Standard Model backgrounds. We compare the predictions for the gluonic k_t-distribution using two different approaches: resummed NLL BFKL and DGLAP evolution. We find that as long as the initial and final virtualities (k_t) along the emission chain are not too close to each other, the NLL resummed BFKL results do not differ significantly from those obtained using standard DGLAP evolution. The saturation momentum Q_s(x), calculated within the resummed BFKL approach, grows with 1/x even slower than in the leading-order DGLAP case.Comment: 24 pages, 8 figures, An improved, slightly more precise NLL resummation is used and the figures are updated accordingly. The conclusions are unchange
