Wizerunek kobiety aktywnej politycznie

"Wraz z upadkiem systemu komunistycznego Polska otworzyła się na Zachód. Rozpoczął się proces demokratyzacji, obejmujący każdą sferę życia społecznego. Zasadnicze zmiany dotyczyć miały także życia politycznego, miały przyczynić się do kształtowania nowej kultury politycznej, stanowiącej zarazem zaprzeczenie porządku obowiązującego w latach PRL-u. Proces demokratyzacji zakończyć się miał wypracowaniem nowych zasad wyłaniania władz państwowych, które we właściwy sposób reprezentować miały tak wszystkich, jak i poszczególnych obywateli kraju."(...

Hydrographic changes in a river system and their influence on the legal classification of watercourses, exemplified by selected tributaries of the San river

The paper presents hydrographic changes in a river system and their influence on the legal classification of watercourses in Poland. As a case study, the watercourse Motwica, right tributary of the river San has been analysed. The main objective of this paper is an attempt to analyse whether the Motwica should be classified as flowing or standing water and the legal grounds for such classification in the Water Law act. On the base of archival and contemporary cartographic materials’ analysis it has been determined that the Motwica should not be classified as natural watercourse because its significant part flows in an artificial channel

Time Evolution of the 3-D Accretion Flows: Effects of the Adiabatic Index and Outer Boundary Condition

We study a slightly rotating accretion flow onto a black hole, using the fully three dimensional (3-D)numerical simulations. We consider hydrodynamics of an inviscid flow, assuming a spherically symmetric density distribution at the outer boundary and a small, latitude-dependent angular momentum. We investigate the role of the adiabatic index and gas temperature, and the flow behaviour due to non-axisymmetric effects. Our 3-D simulations confirm axisymmetric results: the material that has too much angular momentum to be accreted forms a thick torus near the equator and the mass accretion rate is lower than the Bondi rate. In our previous study of the 3-D accretion flows, for gamma=5/3, we found that the inner torus precessed, even for axisymmetric conditions at large radii. The present study shows that the inner torus precesses also for other values of the adiabatic index: gamma=4/3, 1.2 and 1.01. However, the time for the precession to set increases with decreasing gamma. In particular, for gamma=1.01 we find that depending on the outer boundary conditions, the torus may shrink substantially due to the strong inflow of the non-rotating matter and the precession will have insufficient time to develop. On the other hand, if the torus is supplied by the continuous inflow of the rotating material from the outer radii, its inner parts will eventually tilt and precess, as it was for the larger gamma's.Comment: 19 pages, 19 figures; accepted to ApJ; version with full resolution figures may be downloaded from http://users.camk.edu.pl/agnes/publ_en.htm

Wokół rekodyfikacji prawa cywilnego. Prace jubileuszowe

Praca recenzowana / Peer-reviewed paperPrezentowana książka to głos w debacie nad stanem naszej kodyfikacji cywilnej. Jubileusz 50-lecia uchwalenia Kodeksu cywilnego, Kodeksu rodzinnego i opiekuńczego oraz Kodeksu postępowania cywilnego zbiega się z jubileuszem Profesora Janusza Szwai1. Profesor, wybitny cywilista, obchodzi swoje 80. urodziny, mija także 50 lat od obrony przez Niego doktoratu. Jest to doskonała okazja by przyjrzeć się propozycjom zmian prawa cywilnego płynących z różnych środowisk akademickich. Wszak dużą część swojego życia Profesor Szwaja poświęcił pracom legislacyjnym, ich komentowaniu czy krytykowaniu. Sam aktywnie w zmianach różnych kodyfikacji uczestniczył. Jego poglądy zawsze były wyważone. Dziś właśnie taki wyważony głos w dyskusji nad kształtem polskiego prawa cywilnego stał się niezbędny

Optimasi Portofolio Resiko Menggunakan Model Markowitz MVO Dikaitkan dengan Keterbatasan Manusia dalam Memprediksi Masa Depan dalam Perspektif Al-Qur`an

Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis

Search for heavy resonances decaying to two Higgs bosons in final states containing four b quarks

A search is presented for narrow heavy resonances X decaying into pairs of Higgs bosons (H) in proton-proton collisions collected by the CMS experiment at the LHC at root s = 8 TeV. The data correspond to an integrated luminosity of 19.7 fb(-1). The search considers HH resonances with masses between 1 and 3 TeV, having final states of two b quark pairs. Each Higgs boson is produced with large momentum, and the hadronization products of the pair of b quarks can usually be reconstructed as single large jets. The background from multijet and t (t) over bar events is significantly reduced by applying requirements related to the flavor of the jet, its mass, and its substructure. The signal would be identified as a peak on top of the dijet invariant mass spectrum of the remaining background events. No evidence is observed for such a signal. Upper limits obtained at 95 confidence level for the product of the production cross section and branching fraction sigma(gg -> X) B(X -> HH -> b (b) over barb (b) over bar) range from 10 to 1.5 fb for the mass of X from 1.15 to 2.0 TeV, significantly extending previous searches. For a warped extra dimension theory with amass scale Lambda(R) = 1 TeV, the data exclude radion scalar masses between 1.15 and 1.55 TeV

Search for electroweak production of charginos and neutralinos in multilepton final states in proton-proton collisions at root s=13 TeV

Results are presented from a search for the direct electroweak production of charginos and neutralinos in signatures with either two or more leptons (electrons or muons) of the same electric charge, or with three or more leptons, which can include up to two hadronically decaying tau leptons. The results are based on a sample of protonproton collision data collected at p s = 13TeV, recorded with the CMS detector at the LHC, corresponding to an integrated luminosity of 35.9 fb1. The observed event yields are consistent with the expectations based on the standard model. The results are interpreted in simpli ed models of supersymmetry describing various scenarios for the production and decay of charginos and neutralinos. Depending on the model parameters chosen, mass values between 180GeV and 1150 GeV are excluded at 95% CL. These results signi cantly extend the parameter space probed for these particles in searches at the LHC. In addition, results are presented in a form suitable for alternative theoretical interpretations.Sponsoring Consortium for Open Access Publishing in Particle Physic
