Badania nad działalnością legislatur — interdyscyplinarny obszar nauki
Z wprowadzenia: "W okresie żywiołowego i wielokierunkowego rozwoju nauki, z jakim niewątpliwie
mamy obecnie do czynienia, jednym z charakterystycznych zjawisk zachodzących
w świecie akademickim jest samorzutne pojawianie się nowych kierunków, czy
wręcz dyscyplin badawczych. Wynika ono przede wszystkim z potrzeby porządkowania
informacji, której ilość i dostępność zwiększa się gwałtownie i prowadzi
do powstania coraz węższych specjalizacji, usiłujących ogarnąć coraz mniejszy (ale
zarazem coraz „gęstszy”, bo bogatszy w informację) fragment rzeczywistości."(...
The parties on the political scene of Poland of the interwar period, 1918–1939
The article contains a brief overview of the main political parties of the Second Republic of Poland. It outlines the genesis of the most important groups operating in each of the partitions, showing the impact of the political activity of Poles in the occupant countries on the shape of Polish political scene in later years. A particular emphasis is placed on presenting the groups active during the “sovereignty of the Parliament,” i.e. in the years 1919–1926. The Polish Socialist Party (PPS) and National Democracy (ND), portrayed as the main political antagonists, are discussed, as well as the peasants’ parties, acting as the political centre. In addition, the author presents the main political currents representing the Jewish and Ukrainian minorities, and describes the special place of the Polish Communist Party in the political system of that time
Polityczne uwarunkowania polityki prawnej w latach 2005–2007
"Polski parlament nie cieszy się uznaniem ani obywateli1, ani międzynarodowych
instytucji oceniających jego pracę2. Taki stan rzeczy odzwierciedla zarówno słabości
regulacji normatywnej procesu legislacyjnego, jak i niespójny charakter
polskiej sceny politycznej. Niniejsze opracowanie ma na celu zwrócenie uwagi
na wzajemne oddziaływanie norm i zachowań politycznych determinujących
proces stanowienia prawa w Polsce. Słabości zarówno jednej, jak i drugiej sfery,
zilustrowane zostały na przykładzie Sejmu V kadencji."(...
The supreme turbinate and the drainage of the posterior ethmoids: a computed tomographic study
Background: It is generally acknowledged that the posterior ethmoidal cells drain under the superior nasal turbinate (SorNT) or, rarely, under the supreme nasal turbinate (SmeNT), and the sphenoid ostium (SO) opens to the sphenoethmoidal recess. However, detailed relations between these structures are variable, complex and still not clear. There is no reliable data on the prevalence of SmeNT and drainage of the posterior ethmoidal cells under this structure. The aim of this study was to re-evaluate the anatomy of the aforementioned region.
Materials and methods: Multiplanar and three-dimensional reconstruction analysis of 100 thin slice paranasal sinus computed tomography scans.
Results: SmeNT was identified in 77 subjects (136 sides). It formed the ostium to the posterior ethmoidal cell adjacent to the skull base or orbit in 58 subjects (91 sides). This cell drained independently from the remaining posterior ethmoidal cells. The sphenoethmoidal (Onodi) cell drained to supreme meatus in 41 subjects (54 sides), and to superior meatus in 37 subjects (49 sides). SO was always located medial to the posteroinferior attachment of SmeNT, or SorNT (in absence of SmeNT).
Conclusions: Patients with divergent drainage of the posterior ethmoids (with posterior ethmoidal cell draining to the supreme meatus) may require more extensive surgery to avoid persistence or recurrence of inflammatory disease. SmeNT is more common than thought, but due to its posterior and superior location to SorNT, it is rarely seen intraoperatively. If SmeNT is present, SO is always located medial to its posteroinferior attachment. (Folia Morphol 2018; 77, 1: 110–115
Metric gravity theories and cosmology:II. Stability of a ground state in f(R) theories
A fundamental criterion of viability of any gravity theory is existence of a
stable ground-state solution being either Minkowski, dS or AdS space. Stability
of the ground state is independent of which frame is physical. In general, a
given theory has multiple ground states and splits into independent physical
sectors. All metric gravity theories with the Lagrangian being a function of
Ricci tensor are dynamically equivalent to Einstein gravity with a source and
this allows us to study the stability problem using methods developed in GR. We
apply these methods to f(R) theories. As is shown in 13 cases of Lagrangians
the stability criterion works simply and effectively whenever the curvature of
the ground state is determined. An infinite number of gravity theories have a
stable ground state and further viability criteria are necessary.Comment: A modified and expanded version of a second part of the paper which

A mechanochemical strategy for IRMOF assembly based on pre-designed oxo-zinc precursors.
We demonstrate a mechanochemical strategy that allowed the first successful mechanosynthesis of IRMOFs based on an oxo-centred secondary building unit (SBU). The presented study indicates that controlling the acid-base relationship between reagents is key to mechanochemical synthesis of IRMOFs, revealing a pre-assembled oxo-zinc amidate cluster as an efficient precursor for IRMOF mechanosynthesis.The authors would like to acknowledge the project operated within the Foundation for Polish Science Team Programme co-financed by the EU ‘‘European Regional Development Fund’’ TEAM/2011–7/8, and the European Union in the framework of Regional Development Fund through the Joint UW and WUT International PhD Program of Foundation for Polish Science – “Towards Advanced Functional Materials and Novel Devices” (MPD/2010/4) (D.P.) for financial support.This is the accepted manuscript.

Adsorption of chain molecules in pores with crystalline walls: a density functional approach
A microscopic density functional theory of adsorption of chain molecules on the attractive solid surfaces of
crystalline symmetry is developed. The proposed approach is based on the expansions of one-particle functions
into two-dimensional Fourier series. Illustrative calculations for dimers, 8- and 16-mers adsorbed on a
(100) fcc crystal surface indicate the effect of the periodicity of the adsorbing potential on the structure of the
adsorbed layer and thermodynamics of adsorption.Розвинуто мiкроскопiчну теорiю функцiоналу густини для вивчення адсорбцiї ланцюгових молекул на притягальних твердих поверхнях кристалiчної симетрiї.

The catalog of short periods stars from the ''Pi of the Sky'' data
Based on the data from the ''Pi of the Sky'' project we made a catalog of the
variable stars with periods from 0.1 to 10 days. We used data collected during
a period of two years (2004 and 2005) and classified 725 variable stars. Most
of the stars in our catalog are eclipsing binaries - 464 (about 64%), while the
number of pulsating stars is 125 (about 17%). Our classification is based on
the shape of the light curve, as in the GCVS catalog. However, some stars in
our catalog were classified as of different type than in the GCVS catalog. We
have found periods for 15 stars present in the GCVS catalog with previously
unknown period.Comment: New Astronomy in prin
Absolute properties of BG Ind - a bright F3 system just leaving the Main Sequence
We present photometric and spectroscopic analysis of the bright detached
eclipsing binary BG Ind. The masses of the components are found to be 1.428 +-
0.008 and 1.293 +- 0.008 Msun and the radii to be 2.290+-0.017 and 1.680+-0.038
Rsun for primary and secondary stars, respectively. Spectra- and
isochrone-fitting coupled with color indices calibration yield
[Fe/H]=-0.2+-0.1. At an age of 2.65+-0.20 Gyr BG Ind is well advanced in the
main-sequence evolutionary phase - in fact, its primary is at TAMS or just
beyond it. Together with three similar systems (BK Peg, BW Aqr and GX Gem) it
offers an interesting opportunity to test the theoretical description of
overshooting in the critical mass range 1.2-1.5 Msun.Comment: 8 pages, 5 figures, corrected bugs in author lis
Graviton Spectra in String Cosmology
We propose to uncover the signature of a stringy era in the primordial
Universe by searching for a prominent peak in the relic graviton spectrum. This
feature, which in our specific model terminates an increase and
initiates an decrease, is induced during the so far overlooked
bounce of the scale factor between the collapsing deflationary era (or pre-Big
Bang) and the expanding inflationary era (or post-Big Bang). We evaluate both
analytically and numerically the frequency and the intensity of the peak and we
show that they may likely fall in the realm of the new generation of
interferometric detectors. The existence of a peak is at variance with
ordinarily monotonic (either increasing or decreasing) graviton spectra of
canonical cosmologies; its detection would therefore offer strong support to
string cosmology.Comment: 14 pages, RevTex source and 6 figures.p
