In the present paper, values of the psi function for many arguments connected with the golden ratio and Fibonacci numbers are determined or given in alternative form. Moreover, some integral representation of the psi function is found. This is a potential calculation base of values of the psi function for powers of argument. We also note that this integral representation gives better numerical estimation of values of the psi function than the respective Legendre’s integral formula.

Opis:
The election of Bettino Craxi as PSI general secretary marked, from 1976, a very important turning point in thehistory of Italian socialism. His dynamic and charismatic leadership in fact contributed to a profound revisionof its ideological seeds, the so-called scientific Marxism, and above all to the recovery of the humanitarianand libertarian suggestions of pre-Marxist socialism. This led to the clear and definitive condemnation of theMarxist-Leninist model, which had found its practical realization in the Soviet system and in the countriesbeyond the Curtain, and prompted PSI to support the anti-communist dissidence and to establish strongrelations with the Polish opposition and above all with Solidarność. Craxi, both in the role of PSI generalsecretary and as Italian prime minister, was able to provide it with a great political-diplomatic support and alot of concrete help. Up to now, the history of these relations has not yet been adequately studied and thispaper therefore aims to fill the gap.

Opis:
The paper presents the use of the Persistent Scatterers Interferometry (PSI) Synthetic Aperture Radar (SAR) data to determine magnitude of subsidence in area of the town ofWieliczka. The town is home to a unique salt mine, over 700 years old, one of the best known tourist attractions in Poland. Each year the mine is visited by about 1 million tourists from all over the world and in 1978 UNESCO placed it on its first International List of theWorld Cultural and Natural Heritage. There is direct evidence that the mining has been influencing stability of ground and buildings in the town, which is located above the mine. The application of the PSI SPINUA technique made it possible to identify large number of radar targets (with density exceeding 100 PS/km2), suitable for monitoring ground motion in the Wieliczka area. The results show continuous subsidence with average annual movements ranging from a few millimeter per year to 24 mm/yr in the period 1992–2000. The detected subsiding zone very well corresponds to the extent of the underground salt mine. There are also indications of possible connections between the mine-induced subsidence and the presence of the old large landslides occurring on the north-facing slopes south of the Wieliczka Salt Mine.

In this research, the nanocrystalline porous silicon (PSi) films are prepared by electrochemical etching of p types silicon wafers with 15 mA/cm2 etching current densities and 15 min etching time on the formation nanosized pore array. PSi was characterized by the measurement of XRD, FTIR spectroscopy and atomic force microscopy properties (AFM). We have estimated crystallites size from X-Ray diffraction about nanoscale for PSi and Atomic Force microscopy confirms the nanometric size Chemical fictionalization during the electrochemical etching show on the surface chemical composition of PSi. The atomic force microscopy investigation shows the rough silicon surface. Also, it is reported the preparation of colloidal CdS nanoparticles NPs prepared by laser ablation in liquid (LAL) technique by irradiating with a Nd:YAG laser pulses CdS target immersed in methanol and varying the laser fluence 1.32 J/cm2. The structural, morphological and optical of CdS NPs has been studied. XRD measurement disclosed that the CdS NPs were of wurtzite hexagonal crystal structure. Transmission electron microscopy (TEM) investigation revealed that the synthesized CdS particles are spherical and have an average particle size in the range of (25 nm). AFM investigations showed that the produced CdS particles have ball-shape with good disposability. The energy band gap of CdS NPs prepared with 1.32 J/cm2 laser fluence has been determined from optical properties and found to be in the range (2.9 eV). Optical constants of CdS NPs were determined from transmittance and reflectance spectra.The effect of CdS NPs diffusion on properties of PSi Photodetector have reported which reveals that improving in (Al/PSi/Si/Al). The results show that a linear relationship between 1/C2 and reverse bias voltage was obtained. The built-in potential have values depending on the etching time current density and laser flunce. Al/CdSe/PSi/Si/Al photodetector hetrojunction have two peaks of response located at 415 nm and (700 -800nm) with max sensitivity 0.6 A/W. The maximum specific detectivity is 6.8×〖10〗^12 cm•〖Hz〗^(1/2) 〖•W〗^(-1) at 770 nm wavelength.

Opis:
In this paper we present two algorithms that may serve as efficient alternatives to the well-known PSI BLAST tool: SeedBLAST and CTX-PSI Blast. Both may benefit from the knowledge about amino acid composition specific to a given protein family: SeedBLAST uses the advisedly designed seed, while CTX-PSI BLAST extends PSI BLAST with the context-specific substitution model. The seeding technique became central in the theory of sequence alignment. There are several efficient tools applying seeds to DNA homology search, but not to protein homology search. In this paper we fill this gap. We advocate the use of multiple subset seeds derived from a hierarchical tree of amino acid residues. Our method computes, by an evolutionary algorithm, seeds that are specifically designed for a given protein family. The seeds are represented by deterministic finite automata (DFAs) and built into the NCBI-BLAST software. This extended tool, named SeedBLAST, is compared to the original BLAST and PSI-BLAST on several protein families. Our results demonstrate a superiority of SeedBLAST in terms of efficiency, especially in the case of twilight zone hits. The contextual substitution model has been proven to increase sensitivity of protein alignment. In this paper we perform a next step in the contextual alignment program. We announce a contextual version of the PSI-BLAST algorithm, an iterative version of the NCBI-BLAST tool. The experimental evaluation has been performed demonstrating a significantly higher sensitivity compared to the ordinary PSI-BLAST algorithm.

Opis:
The paper presents results of SPINUA (Stable Point Interferometry over Unurbanised Areas) Persistent Scatterers Interferometry (PSI) processing chain to study Earth surface deformations along the SW coast of the Gulf of Gdańsk, along the SE part of the Baltic Sea. As the input for SPINUA techniques 40 descending ERS-1/2 SLC (Frame = 251, Track = 36) images from the period 1995-2001 has been used. The area of interest (AOI) includes few cities and several towns, villages and harbors. The low lying coastal areas of the SW part of the Gulf of Gdańsk are at risk of floods and marine erosion. The PSI results, however, did not reveal the presence of a regional scale, spatially consistent pattern of displacements. It is likely that any crustal deformations in the AOI simply do not exceed +2 mm/year, which is the velocity threshold we assumed to distinguish between moving and non-moving persistent scatterers (PS). Importantly, for the most part the urban areas of the main cities (Gdańsk, Gdynia and Sopot) results show ground stability. Nevertheless, significant downward movements up to several mm/year, are locally noticed in the Vistula river delta - alluvial plain system located in the coastal zone east of Gdańsk as well as in the inland area west of the Gdańsk city. Indeed, the highest subsidence rates (-12 mm/year) was observed in the Gdańsk petroleum refinery constructed on alluvial sediments. Thus the anthropogenic loading and consolidation of the recent deposits can locally be an important factor causing ground subsidence.

Opis:
We investigated the influence of personality and culture on effects of mortality salience (MS) over cultural worldview defense (CWVD). We hypothesized that CWVD reactions to MS differ between Germany and Poland because of the higher conservatism of the latter country, and that they are moderated by action vs. state orientation. In this study German (N=112) and Polish (N=72), participants were exposed either to MS or to a control condition (dental pain). Punishment ratings to trivial offences and serious social transgressions were measures of CWVD. Results showed that social transgressions in both conditions were more strongly punished in Poland than in Germany. Additionally, compared to the control condition, under MS action oriented punished serious transgressions more strongly in Germany whereas state oriented punished serious transgressions more strongly in Poland. That is, the effects of MS on CWVD are moderated by personality and culture. We interpret the opposite pattern of punishment to serious social transgressions given by action and state orientedin in Germany and Poland, respectively, according to the higher emotional autonomy of action-oriented persons in either culture.

This paper presents a study to ensure the minimum values of Ra and Rz, and the maximum value of MRR when external cylindrical grinding by the PSI method. The experiments were performed according to the orthogonal Taguchi L9 matrix with the input parameters including workpiece speed, feed rate, and depth of cut in the conventional grinding machine. Analysis of experimental results by Pareto chart showed that the feed rate and the depth of cut most influence on Ra and Rz, respectively. Feed rate and depth of cut all have a great influence on MRR. Meanwhile, the workpiece speed has a negligible effect on all three output parameters. The research results showed that to obtain the minimum values of Ra and Rz, and maximum of MRR, the workpiece speed, feed rate, and depth of cut were 400 rev/min 37.7 mm/min, 0.09 mm/rev, and 0.02 mm, respectively.

This work presents some aspects related to the designing of a roller for stands that are intended to determine the parameters of the transmission of a vehicle, such as braking force, wheel revolutions, etc. The computational scheme of simply supported beam is used to create an analytical mechanical-mathematical model through which a multicriteria optimization problem has been solved. A finite element macro and submodel of the roller has been created, and by using the R1MS technique, the fatigue strength in the welding seams in the roller has also been determined. A parametric analysis is accomplished to determine the influence of the thickness of the base steel and the covering ebonite layer on the perimeter change of the outer surface, taking into account the physical non-linearity of the outer layer.

Opis:
The photochemical characteristics of mesophyll and bundle sheath chloroplasts isolated from the leaves of C4 species were investigated in Zea mays (NADP-ME type), Panicum miliaceum (NAD-ME type) and Panicum maximum (PEP-CK type) plants. The aim of this work was to gain information about selected photochemical properties of mesophyll and bundle sheath chloroplasts isolated from C4 plants grown in the same moderate light conditions. Enzymatic as well as mechanical methods were applied for the isolation of bundle sheath chloroplasts. In the case of Z. mays and P. maximum the enzymatic isolation resulted in the loss of some thylakoid polypeptides. It was found that the PSI and PSII activities of mesophyll and bundle sheath chloroplasts of all species studied differed significantly and the differences correlated with the composition of pigment-protein complexes, photophosphorylation efficiency and fluorescence emission characteristic of these chloroplasts. This is the first report showing differences in the photochemical activities between mesophyll chloroplasts of C4 subtypes. Our results also demonstrate that mesophyll and bundle sheath chloroplasts of C4 plants grown in identical light conditions differ significantly with respect to the activity of main thylakoid complexes, suggesting a role of factor(s) other than light in the development of photochemical activity in C4 subtypes.
