Molecular Phylogeny and Estimated Time of Divergence in the Central European Melanopsidae: Melanopsis, Fagotia and Holandriana (Mollusca: Gastropoda: Cerithioidea)
Marcin Smoleń , Andrzej Falniowski
Folia Malacologica , 2009, DOI: 10.2478/v10125-009-0001-4
Abstract: Three European melanopsids: Melanopsis parreyssii (Philippi, 1847) from Ochiul Mare (Romania), Fagotia acicularis (A. Férussac, 1828) from a spring near Crisul Negru (Romania), and Holandriana holandri (C. Pfeiffer, 1828) from Lake Skutari (Montenegro), as well as Melanopsis costata Oliver, 1804 from Iraq, are considered is this paper. Eight partial sequences of ribosomal 18S, and seven of mitochondrial COI were analysed. Maximum likelihood trees based on 18S confirm the placement of the Melanopsidae within the Cerithioidea, as well as the monophyly of the latter group. The COI-based tree confirms the placement of the Melanopsidae within the Cerithioidea, but does not confirm the monophyly of either Melanopsidae or Cerithioidea. The results suggest that Fagotia should be synonymised with Melanopsis, Holandriana is a distinct genus, and Melanopsis costata is not congeneric with M. parreyssii. The application of molecular clock, with one point calibration for COI for the Hydrobiidae, estimated the times of divergence as 2.53±0.56 Mya for M. parreyssii and F. acicularis, 9.49±1.67 Mya for M. parreyssii and H. holandri, and 10.71±1.88 Mya for F. acicularis and H. holandrii. 2.5 Mya coincides with the beginning of the glacial period in Europe, and 8-12 Mya was the time when Lake Pannon covered the largest area.

Abstract: The use of formalin-fixed paraffin-embedded (FFPE) tissues for HPV DNA detection by PCR from biopsy materials is not entirely clear in retrospective studies. The aim of our study was to evaluate the usefulness and efficiency of FFPE tissues from laryngeal cancer (LSCC) in HPV detection by immunohistochemistry reaction (IHC) and PCR-DNA enzyme immunoassay method (PCR/DEIA) and to compare with HPV detection from DFT. HPV-DNA was amplified from 54 FFPE tissues from LSCC specimens by the short PCR fragment (SPF10) primer set using PCR/DNA method and monoclonal anti Human Papillomavirus antibodies in IHC. In the same patients 54 specimens were collected and immediately deep-frozen and stored at (-70 °C) to (-80 °C). All the FFPE and deep-frozen tissue (DFT) specimens were positive for -globin amplification. HPV was detected by two methods (SPF10 PCR/DEIA and IHC) in 14 (25.92%) out of 54 specimens from FFPE. Significant differences were found between the HPV detection using PCR/DEIA method and IHC method in FFPE tissues. The comparative analysis of the 54 samples after assuming PCR method in FFPE tissues showed accuracy of 92.6%, sensitivity of 90.5% and specificity of 93.9%. The FFPE tissues method has high sensitivity, specificity and accuracy when used to detect HPV DNA by PCR reaction and it is comparable to DFT results. DNA quality of FFPE samples is adequate and it can be used in HPV-DNA detection and in retrospective studies on LSCC.
Soft power w polityce zagranicznej Turcji wobec regionu Bliskiego Wschodu

Annales UMCS, Sectio K (Politologia) , 2011, DOI: 10.2478/v10226-011-0005-3
Abstract: The subject of analysis in the article is soft power in the foreign policy of Turkey towards the Region of Middle East. In the conditions of the parameter change of the international system and in particular, appearance of new outside-state subjects and new quality phenomena and dangers, soft power has become an effective instrument enabling states to affect the external system as well as realization of the aims of foreign policy. Soft power model in Turkey's foreign policy towards Middle East is conditioned by internal factors: dynamically developing economy, access to energetic resources and internal factors such as geopolitical location and current shape of the international system. Realization of soft power in Turkey's foreign policy towards the Middle East region is accomplished, among others, through mediation in local conflicts, political and economic cooperation, propagating principles of liberal economy and democracy, promotion of culture and fostering the civil society. Analyzing effectiveness of soft power in Turkey's foreign policy towards the Middle East region, the author has concluded that this model is "the catalyst" of the regional cooperation and of civil society development as well as an effective tool of state image promotion abroad. However, it is not a sufficient tool of extinguishing international conflicts.
VideoCar in finan ne plati zajema cestnih podatkov v ob inah : VideoCar and the Financial Aspects of Community Road-Data Acquisition

Geodetski Vestnik , 2003,
Abstract: In the article there are two (often overlooked) aspects laid out regarding the important role and the influence of geodesy on the life of communities. First, the possibilities enabling communities to improve their financial management are emphasized. Such possibilities are often based on unbiased real-estate listings which can be provided by geodesy. The other type of communication between a community and geodesy is imposed by the law and as such supports communities in their efforts to reach the aims outlined by their spatial planning and managament departments.
Changes in the Classroom: Accomplishments and Obstacles of an Innovative Proposal in the View of Teachers  [PDF]

Abstract:

In 1999, the Judaic Education Council of Rio de Janeiro implemented the Educational Innovation Program (EIP) in the Israeli schools of that city so as to meet the new trends in Brazilian education. The present work was designed to evaluate the modifications taking place in the school environment as a result of EIP implementation, a program whose core idea is to work on knowledge building from the Piagetian perspective, active learning in Dewey’s conception, and multiple intelligences as presented by Gardner. In order to assess the chosen program, we used a qualitative approach through semi-structured interviews with the participants and observation of classrooms from the first to the fifth grade of elementary school. The results of our study showed that from the implementation of the program, the professionals involved were more motivated to search for information and update their knowledge so as to meet the differences between students, using a diversity of strategies and dynamic activities which led to encouraging student autonomy as regards their learning. The reported difficulties for the work to proceed were mainly about the schoolwork timetable planned for both the project and the subjects, and teachers having to cover an extensive curriculum, common to other Brazilian schools. In every innovative program, it is important for the professionals involved in it to continually re-evaluate its development, searching for changes or alternatives as difficulties are encountered. The aim of the present paper is to report the main findings of this research, as well as indicate the strengths and precautions to take in educational innovation proposals whose primary focus is classroom innovation.

Optimization of organization and access to basic spatial data
Rada Rikanovi?,Domen Smole
Geologija , 2005,
Abstract: Geologic Survey of Slovenia acquired, in the last few years numerous digital spatial data of various sources and scales. Amounts of data constantly increased which lead to considerations on their organization in a unique collection to which the users could havedirect access. For surveying the already organized spatial data the ESRI ArcIMS program was selected, whereas for organization of spatial data themselves and for certain specific users requirements (cropping of raster data to a selected domain) the mentioned GIS internet solution had to be upgraded with additional program modules. In the following paper factual internet GIS solutions shall be presented especially from the aspect of simplification and increased efficiency of existing working procedures.
CdSe/ZnSe quantum dot with a single Mn$^{2+}$ ion - a new system for a single spin manipulation
Tomasz Smoleński
Physics , 2014, DOI: 10.1063/1.4913831
Abstract: We present a magneto-optical study of individual self-assembled CdSe/ZnSe quantum dots doped with single Mn$^{2+}$ ions. Properties of the studied dots are analyzed analogously to more explored system of Mn-doped CdTe/ZnTe dots. Characteristic sixfold splitting of the neutral exciton emission line as well as its evolution in the magnetic field are described using a spin Hamiltonian model. Dynamics of both exciton recombination and Mn$^{2+}$ spin relaxation are extracted from a series of time-resolved experiments. Presence of a single dopant is shown not to affect the average excitonic lifetime measured for a number of nonmagnetic and Mn-doped dots. On the other hand, non-resonant pumping is demonstrated to depolarize the Mn$^{2+}$ spin in a quantum dot placed in external magnetic field. This effect is utilized to determine the ion spin relaxation time in the dark.
Scots pine (Pinus sylvestris L.) ecosystem macronutrients budget on reclaimed mine sites—stand trees supply and stability  [PDF]
Marcin Pietrzykowski
Natural Science (NS) , 2010, DOI: 10.4236/ns.2010.26074
Abstract: The aim of this study was to determine the sources, accumulation rate and relationships between macronutrients in reclaimed mine soils (RMS) and aboveground plant biomass on external slopes of lignite mines in central Poland. The study was conducted on two different types of sites with 10-year-old Scots (Pinus sylvestris L.) pine stands located on Quaternary loamy sands (QLS) and on Tertiary acidic carboniferous sands following neutralisation (TCS). The control plot was located in the same vicinity on an external slope in a natural pine ecosystem on a Haplic Podzol in a young mixed coniferous forest habitat (NPE). The nutrient resources, apart from N, were higher in RMS than in comparable Haplic Podzols, however, N primarily accumulated in the mineral horizons. In forest soils, the main macronutrient resources were accumulated in organic horizons, which in natural soils of coniferous forest habitats constitute the main source of nutrients. The proportion of individual macronutrients accumulated in the biomass vs. pools in soil was much lower on the external slope RMS than in the natural site, which in view of the potential richness of RMS, indicated poorer sorption and utilization of macronutrients in aboveground plant biomass than in natural habitats. Other important linear correlations (p = .05) were found between the sources of nutrients in RMS and elements accumulated in biomass (most clearly in case of K, Ca and Mg), which indicates important relationships between soil and vegetation in the first stages of ecosystem development as stimulated by reclamation.
Labor Productivity Parity vs Trend of Exchange Rate  [PDF]
Marcin Jedrzejczyk
Modern Economy (ME) , 2012, DOI: 10.4236/me.2012.36099
Abstract: Translation, understood as a process of restating the value from a particular currency to another currency, is based on the market exchange rate. So in practice, almost every value in terms of goods, assets, liabilities, and wages is converted to US dollars according to the current exchange rate. A fundamental method of translation was originated by Balassa and Samuelson in 1964 who explained that the main driver of the exchange rate is productivity, which is higher in developed countries and lower in poor countries. That is why these differences must be eliminated in order to make the exchange rate useful. However, different research verifying the Balassa-Samuelson approach, especially in the long run, had revealed some inconsistencies. Recently the Balassa-Samuelson theory has been enriched by more precise determination of productivity; specifically, an appropriate ratio for the translation procedure has appeared labor productivity Q defined as quotient of real GDP to cost of labor. The main aim of the paper is to present statistical verification of labor productivity parity as the main driver of the exchange rate. In the research, there will be an estimation of parameters of linear function in which the dependent variable represents the average exchange rate for the period between a particular country and the USA, and the independent variable is the average hourly pay quotient modified by labor productivity parity. If the linear function parameters describe the y = x relation, the theory of labor productivity as the determinant of exchange rate behavior will be confirmed.
Cosmic Engineering: Moving Asteroids  [PDF]
Marcin Misiak
International Journal of Astronomy and Astrophysics (IJAA) , 2013, DOI: 10.4236/ijaa.2013.34060
Abstract:

This paper presents methods of orbit transfer for small planetoids from the main belt to the future colonies on Mars using current technologies. The results show that by using nuclear weapon or even kinetic energy weapon (for retrograde bodies) asteroids with masses up to about 100 tons can be moved. Both options assume that asteroid will survive explosion.
