Scattering states of a particle, with position-dependent mass, in a double heterojunction

In this work we obtain the exact analytical scattering solutions of a particle (electron or hole) in a semiconductor double heterojunction - potential well / barrier - where the effective mass of the particle varies with position inside the heterojunctions. It is observed that the spatial dependence of mass within the well / barrier introduces a nonlinear component in the plane wave solutions of the continuum states. Additionally, the transmission coefficient is found to increase with increasing energy, finally approaching unity, whereas the reflection coefficient follows the reverse trend and goes to zero.Comment: 7 pages, 6 figure

ANALISIS PUTUSAN HAKIM TERHADAP SENGKETA PEMBATALAN PENDAFTARAN MEREK DALAM PUTUSAN PENGADILAN NIAGA SURABAYA NOMOR 08/HAKI/2007.PN.NIAGA SBY

Based on Law No. 15 of 2001 concerning Brands and Law Number 20 of 2016 concerning Brands and Geographical Indications explains that the role of brands is very important, especially in maintaining good business competition. The brand can be used as a tool to explain the origin of the product, know the quality of the product, as well the authenticity of the product. The problem of Intellectual Property Rights, especially in the field of brands, is a problem that will continue to develop following the development of the world of science. This can be seen from the increasing prevalence of crime, one of which is in the current trade sector. Where in the registration of the mark is filed by the Applicant in bad faith, where the mark has similarities in essence or in its entirety with the wellknown mark belonging to the other party for goods and/or the like. This study aims to determine what the legal consequences are for Brands that have been canceled by the Directorate General of Brands and Geographical Indications and to find out how the Surabaya commercial court judges consider in deciding case No.08/HAKI/2007/PN.Niaga Sby. The research method used in this study is a normative legal research method where the source of the data used is obtained based on primary legal materials, namely Court Decision No.08 / HAKI / 2007 / PN.Niaga Sby and secondary legal materials such as books, journals, and so on. The outputs targeted in this research are mandatory outputs in the form of accredited national journals.  Keywords: IPR, Cancellation, Registration, Bran

VATANDAŞ: RURALIST NEWSPAPER OF SALONICA THIRD CLUB OF COMMITTEE OF UNION AND PROGRESS

Halkçılığın ve köycülüğün belirgin bir gelişme gösterdiği II. Meşrutiyet döneminin ilk yıllarında Selanik'te İttihat ve Terakki Üçüncü Kulübü tarafından köylüler için Vatandaş isimli bir gazete çıkarılmıştır. Dönemin halkçı ve köycü söylemine, İttihat ve Terakki kulüplerine ışık tutmak üzere bu makalede, adı geçen gazete değişik boyutlarıyla incelenecektir. Vatandaş gazetesi ile yakından ilişkili olduğu için, yine Selanik'te yayımlanan Tenvir-i Efkar dergisi de bu incelemeye dahil edilmiştir. The newspaper called Vatandaş (Citizen) was issued in Salonica by the Third Club of The Committee of Union and Progress during the early years of the II. Constitutional Era (Ottoman Empire), when ruralism and populism were making notable progress. With an aim to set light on the discourse of populism and ruralism about that period, and to Committee of Union and Progress clubs, the mentioned newspaper will be analysed in varied dimensions. The journal Tenvir-i Efkar published in Salonica is also incorporated into this article due to its close relation to the newspaper Vatandaş

Efektifitas Pemberdayaan Kelompok Ibu Rumah Tangga Dalam Peningkatan Pengetahuan, Sikap Dan Praktek Pemberantasan Demam Berdarah Dengue Di Kelurahan Adiarsa Barat Kabupaten Karawang Provinsi Jawa Barat

. Adiarsa Barat village is one of endemic area of the Dengue Haemorrhagic Fever (DHF) in Karawang. That village had not touched by community empowerment yet. The purpose of this research was to knoweffectiveness of housewives empowerment for eradication of DHF with breeding site control. This research was an experimental quation, with intervention in one location and control in other. The final result was hoped that the respondents would increase of knowledge, attitude and practice. The data of housewife behaviour was collected by intervew. This research found that there was the increase of housewife's group behaviour, followed by the increase of housewifes behaviour at intervention area with P value < 0,05. Although housewifes behaviour at control area hasn't increase with P value> 0,05. This reaserch suggested that people participation needed to be identified first then monitored periodically, so that their behaviour to eradicate DHF disease would be a habit or permanent

New exact solution of the one dimensional Dirac Equation for the Woods-Saxon potential within the effective mass case

We study the one-dimensional Dirac equation in the framework of a position dependent mass under the action of a Woods-Saxon external potential. We find that constraining appropriately the mass function it is possible to obtain a solution of the problem in terms of the hypergeometric function. The mass function for which this turns out to be possible is continuous. In particular we study the scattering problem and derive exact expressions for the reflection and transmission coefficients which are compared to those of the constant mass case. For the very same mass function the bound state problem is also solved, providing a transcendental equation for the energy eigenvalues which is solved numerically.Comment: Version to match the one which has been accepted for publication by J.

Effective Mass Dirac-Morse Problem with any kappa-value

The Dirac-Morse problem are investigated within the framework of an approximation to the term proportional to $1/r^2$ in the view of the position-dependent mass formalism. The energy eigenvalues and corresponding wave functions are obtained by using the parametric generalization of the Nikiforov-Uvarov method for any $\kappa$-value. It is also studied the approximate energy eigenvalues, and corresponding wave functions in the case of the constant-mass for pseudospin, and spin cases, respectively.Comment: 12 page
