Published: April 2013

Abstract
Improvements of modern manufacturing techniques implies more efficient production but also new challenges for coordinate metrologists. The crucial task here is a coordinate measurement accuracy assessment. It is important because according to technological requirements, measurements are useful only when they are stated with their accuracy. Currently used methods for the measurements accuracy estimation are difficult to implement and time consuming. It is therefore important to implement correct and validated methods that will also be easy to implement. The method presented in this paper is one of them. It is an on-line accuracy estimation method based on the virtual CMM idea. A model is built using a modern LaserTracer system and a common test sphere and its implementation lasts less than one day. Results obtained using the presented method are comparable to results of commonly used uncertainty estimation methods which proves its correct functioning. Its properties predispose it to be widely used both in laboratory and industrial conditions.

Background.The aim of the study was to evaluate the efficacy, as well as the acute and late toxicity of an accelerated hypofractionated 3DCRT schedule as radical treatment in patients with organ confined glottic cancer cT1-2N0.
Patients and methods. Between June of 2004 and September 2010, 47 retrospectively selected patients (29 males, 18 females) diagnosed with organ confined T1 or T2 glottic cancer, were treated with external 3DCRT in an accelerated hypofractionation schedule. The median age was 70 years. A dose of 64.4 Gy in 28 daily fractions was prescribed. The primary study endpoints were to assess the acute and late effects of radiation toxicity, according to the EORTC/ RTOG scale, as well as the therapeutic impact of this schedule in terms of local recurrence.
Results. The median follow up was 36 months. At the end of radiotherapy, grade I, II and III acute toxicity was observed in 34, 9 and4 patients, respectively. Late grade I and II toxicity was observed in 25 and in 8 patients respectively. Only two local recurrences were observed, 15 and 24 months post 3DCRT respectively.
Conclusions. Our radiotherapy schedule achieves a high locoregional control rate with the advantage of voice preservation. The proposed hypofractionated schedule can be recommended as a standard radiotherapy treatment, since these results are comparable with those of conventional fractionation schedules.
Mapping as a Spatial Data Source
Authors: Hudecová Ľubica 
Published: April 2013

Abstract
The basic database for a geographic information system (BD GIS) forms the core of a national spatial data infrastructure. Nowadays decisions are being made about the potential data sources for additional data updates and refinement of the BD GIS. Will the data from departmental or other information system administrators serve for this purpose?
This paper gives an answer as to whether it is advisable to use “geodetic mapping” (the results realized in the process of land consolidation) or “cadastral mapping” (the results realized in the process of the renewal of cadastral documentation by new mapping) for additional data updates. In our analysis we focus on the quality parameters at the individual data element level, namely the positional accuracy, attribute accuracy, logical consistency, and data resolution. The results of the analysis are compared with the contents of the Object Class Catalog of BD GIS (OCC), which describes the group of objects managed by BD GIS and defines the data collection methods, types of geometry and its properties.

Abstract
Ibrahim W.A.L., Busse P. 2012. Migration of passerines through some protected areas in the
eastern part of Egypt. Ring 34: 69-205.
The fieldwork - catching and ringing birds using mist-nets - were conducted at several sites during both spring and autumn migration seasons in 2001-2008. These sites were: Burullus Protected Area, Wadi El Rayan Protected Area, Hurghada, Sharm El Shiekh (Ras Mohamed National Park), Saluga and Ghazala Protected Area and Wadi El Gemal Protected Area. Altogether 21 site/seasons were covered (9 in spring and 12 autumn). In the most cases the work in a season lasted 1-2 months and the timing of work was not standardized. This make the results not exactly compatible, but still this is a first so wide study of the mainly passerine migration over the area. The aim of this paper is to make accessible the basic information on passerine migration there. Some non-passerines, that are more easily caught with mist-nets or that are caught ocassionally are listed too. Altogether 19 748 individuals of 117 species were ringed in spring and 11 238 individuals in autumn. The data are presented in the text as faunistics style lists of birds caught in spring and autumn separately, as tables of birds ringed at stations and those that show relative abundance and dominance of species and in Appendices I and II (for spring and autumn) as maps with average numbers per station and as seasonal number dynamics - total for seasons and yearly, if possible. The data included in the paper are treated as a source information about migration over the area studied, while the more detailed data about migration pattern, measurements, stopover ecology will be evaluated in next papers being under preparation.

Rural schools: wrinklers for mayors?
All municipalities in the Czech Republic are obliged to guarantee access to basic education for children eligible for compulsory schooling. To meet this task, most municipalities establish a primary school whose operational and investment costs they cover. Running a school can be very demanding for rural municipalities. The article presents the results of a questionnaire survey which involved founders (mayors) the so-called small schools with composite classes, situated mainly in small rural municipalities. Based on these results examines the main stereotypes associated with the notion of small rural schools. A hypothetical balance between what the municipality must invest and what benefits the school brings is sought.
ICT-Enabled Climate Change Education for Sustainable Development Across the School Curriculum

Published: April 2013

Abstract
A radical shift in pedagogy is necessary for information and communication technology (ICT) to enhance teaching and learning for sustainability. Climate change takes an inter/crossdisciplinary approach attempting to synthesise diverse ideas and observations concerning global warming. This paper deals with the integration of climate change across the school curriculum through a web-based hypermedia application entitled ICT-enabled integration of climate change education (CCE) that is used as a resource for the EU-funded project ICT-enabled education for sustainable development (ESD). The web-based environment includes interactive activities and supportive material on climate change and is open to all the six forms at the primary school level. The methodological approach used merges ICT, ESD, critical pedagogy and CCE principles and practices. Drupal (content management system) was chosen as the back-end system of our hypermedia learning environment. The main learning content is composed of learning objects (LOs) created through the authoring tool Adobe Flash. The combination of Drupal and Flash provides a dynamic and adaptable learning environment. Through this web-based learning environment that integrates six thematic areas supported by various ICT tools, learners are expected to gain insight into how climate change is altering the planet, potential impacts on the future, and how they can intervene to address its effects.
The structure of the fréchet space s regarding the series ∑ƒn(xn)
Authors: Šalát Tibor , Vadovič Peter 
Published: April 2013

Abstract
We investigate the subsets of the Fr´echet space s of all sequences of real numbers equipped with the Fr´echet metric ρ from the Baire category point of view. In particular, we concentrate on the “convergence” sets of the series ∑ƒ<sub>n</sub> (x<sub>n</sub>) that is, sets of sequences x = (x<sub>n</sub>) for which the series converges, or has a sum (perhaps infinite), or oscillates. Provided all ƒ<sub>n</sub> are continuous real functions, sufficient conditions are given for the “convergence” sets to be of the first Baire category or residual in s.
Formal analysis of security protocols for wireless sensor networks
Authors: Novotný Marián 
Published: April 2013

Abstract
Design of security protocols is notoriously error-prone. For this reason, it is required to use formal methods to analyze their security properties. In the paper we present a formal analysis of the Canvas protocol. The Canvas protocol was developed by Harald Vogt and should provide data integrity inWireless Sensor Networks. However, Dieter Gollmann published an attack on the protocol. We consider the fallacy of the Canvas scheme in different models of the attacker and present a solution for correcting the scheme.We propose a formal model of the fixed Canvas protocol in the applied pi-calculus. This model includes a model of the network topology, communication channels, captured nodes, and capabilities of the attacker. Moreover, we formulate and analyze the data integrity property of the scheme in the semantic model of the applied pi-calculus. We prove that the fixed Canvas scheme, in the presence of an active adversary, provides data integrity of messages assuming that captured nodes are not direct neighbors in the communication graph of a sensor network. Finally, we discuss the applicability of the proposed formal model for analysis of other WSN security protocols.

Abstract
Multiple sclerosis (MS) is an autoimmune demyelinating disorder of the central nervous system characterised with a complex system of interactions between proinflammatory and anti-inflammatory cytokines in its course.
Aim: The aim of the present study was to investigate the serum levels of cytokines TNF-α, IFN- γ, IL- 4 and IL- 10 in female patients with MS and healthy individuals, the changes occurring in the relapse and remission phases of the disease and their correlation with the severity of the neurological deficit.
Patients and methods: Thirty-five women with relapsing-remitting MS were examined. The patients’ age ranged between 18 and 50 years and MS was verified clinically and by magnetic resonance imaging according to the McDonald criteria. Thirteen of the patients were treated with interferon-β-1b. The serum concentrations of TNF-α, IFN- γ, IL- 4 and IL- 10 were determined twice - in relapse and in remission - using an enzyme-linked immunosorbent assay (EL ISA). The control group consisted of 35 age-matched healthy females. Results: The comparison of cytokine serum concentrations during the two phases of the disease showed significant elevation of the TNF-α serum levels in the relapse phase and of IL- 4 - in the remission phase. The comparison between the patients and the healthy control subjects demonstrated statistically significant lower concentrations of TNF-α in remission patients and higher concentrations of IL- 10 in relapse patients. The patients with interferon-β-1b treatment showed different profile of cytokine secretion from the patients without interferon-β-1b treatment. Interferon-β-1b-treated patients showed significantly lower serum levels of TNF-α and IFN- γ during the relapse phase and higher TNF-α and IL- 10 serum levels during the remission phase compared with the untreated patients.
Conclusions: Serum levels of TNF-α and IL- 4 objectively reflect the immune response during relapse and remission of the disease. The severity of neurological deficit as estimated with the expanded disability status scale (EDSS ) does not depend on the serum levels of TNF-α, IL- 10 and IFN- γ in the two phases of MS.

The institution of co-operation in border regions – examples of the activities of Polish organisations
Authors: Szmigiel-Rawska Katarzyna 
Published: April 2013

Abstract
The aim of this study was to determine the conditions of sustainable (long-term) partnerships for the development of cross-border co-operation with regard to how they are formed and how they function. The analysis concerns partnerships created as a part of the PHARE CBC Small Project Fund between 2000-2003. It focuses on the sustainability of these partnerships through the prism of their duration and the frequency of actions taken. The conceptual assumption was that cross-border cooperation can be seen as an institution and analysis used the concept of path dependency. Entering into relations of co-operation in a border region in Poland is a behavioural norm, but co-operation is not seen in the light of the benefits of entering into a relationship, that is, not in the light of the direct benefits of co-operation.

Linear Closed-form Solution and Finite-element Analysis of an Active Tensegrity Unit
Authors: Kmeť Stanislav , Platko Peter 
Published: April 2013

Abstract
Results of the linear closed form solution of an active or adaptive tensegrity unit, as well as its numerical analysis using finite element method are presented in the paper. The shape of the unit is an octahedral cell with a square base and it is formed by thirteen members (four bottom and four top cables, four edge struts and one central strut). The central strut is designed as an actuator that allows for an adjustment of the shape of the unit which leads to changes of tensile forces in the cables. Due to the diagonal symmetry of the 3D tensegrity unit the closed-form analysis is based on the 2D solution of the equivalent planar biconvex cable system with one central strut under a vertical point load.
An Energetic Approach for Numerical Analysis of an Interface crack in Shearing Mode
Authors: Vodička Roman 
Published: April 2013

Abstract
A mathematical model of a layered structure and initiation and growth of interface cracks are presented. A numerical approach for solving this problem is described, with the emphasis to the analysis of a shearing-mode crack. The model defines a scalar damage variable in the interface and also plastic tangential slip, which increases the fracture toughness in the shearing crack mode. An energetic formulation governing the adhesive damage until it breaks is proposed. The approach is also tested numerically to demonstrate the behaviour of the model and to assess its suitability in a particular physical situation.
Simultaneous determination of artificial sweeteners in possible counterfeited wines, using high performance liquid chromatography with DAD detection

Published: April 2013

Abstract
Increased use of food, beverages or drugs containing synthetic sweeteners presents a real danger to health, which is why the EU Member States had to establish a system of regular surveys to monitor sweetener consumption. In case of wine industry, according to law no. 244/2002, Romania prohibits the addition of synthetic sweeteners in wine in order to obtain sweet wine. The official method for detection of adulterated sweet wines with synthetic sweeteners is TLC-Thin Layer Chromatography. However, quantitative methods of analysis are needed to measure levels of sweeteners in different food matrices and high performance liquid chromatography has proved to be a powerful tool for quantitative analysis of compounds at traces levels. In this paper, a high performance liquid chromatographic (HPLC) method for the simultaneous separation and determination of three of the most popular artificial sweeteners (acesulfame potassium, saccharine and aspartame) in a single injection was developed. The described method is rapid, accurate and highly sensitive. Detection limit were 4 mg/L for acesulfame K, 1 mg/L for saccharine and 9 mg/L for aspartame respectively. The precision of the method was about 2% and recovery ranged between 92.6% and 103.3%. There were analyzed commercial wine samples, in order to detect possible counterfeits-sweet and medium sweet wines. Therefore, of the 20 analyzed wine samples, only two samples consisting in wine sweet table, were counterfeited by adding saccharin.
Le choix de la forme du dialogue : le dialogue des Athéniens et des Méliens (Thucydide. V,85-113)
Authors: Roman Agathe 
Published: April 2013

Agathe Roman, Choosing the dialogue form: the Melian dialogue (Thuc. V.85-113), DHA 33/1, 2007, 9-22.
Abstract: The speeches in Thucydides are usually studied in a historical point of view. Without trying to prove whether the Melian dialogue truly took place in history or not, the present paper wishes to examine why Thucydides chose the dialogue form -an exception in the Peloponnesian war - instead of the speech, more usual in his work. Considering the conditions in which this exchange took place according to the historian, and examining the uses of the dialogue and the speech, it will be possible to conclude that the dialogue form can express the imbalance of the Melian exchange. Using this form, Thucydides shows the Athenian power without the speech's rhetoric.

Javier Andreu Pintado, A chapter on public construction's spending in the Roman Provinces under Domitian. The imperial initiative, DHA 34/2., 2008, 115-143.
Abstract : This article is the first sketch of a study on the actions conducted by the emperor Domitian in the provinces of the Roman Empire. As there has not been any real investigation on the subject, we start by taking into account the epigraphical datas on imperial spending. From then, we study the chronological and geographical repartition of the edilitarian activity of Domitian in the provinces, as well as the consequences of his damnatio memoriae for the epigraphical sources, which supply us with the main part of our information on his reign.
Les enjeux du grand marché intérieur européen
Authors: Lebègue Daniel 
Published: April 2013

The Unified European Market at Stake
The achievement of a unified european market is a necessity. Eventually, any financial intermediary in Europe should be able to make business in other countries without being submitted to other authorities than his own country's. The European Commission's approach is based on three points. Firstly a free circulation of capital, which implies the end of safeguard clauses, the freedom of emitting and buying securities, and a last step that should suppress all remaining restriction on financial loans, on monetary market operations, and on deposits and assets on bank accounts. Second point, the free circulation of services and financial products. This is already done for securities and transborder operations, according to the Luxemburg Court's decision on december 4th 1986. The banking sector-especially mortgage credit- is under study. The third point consists in harmonizing legal regulations, consumer protection and information, and electronic fund transfers, and protection of public savings.
The success of european financial integration depends on three main conditions. First, each country should work towards this opening; France's efforts in this direction are quite important. Second, there should be a harmonization from the top, by means of protection of savers and by avoiding, when difficulties arise, a return to national protectionist measures. The third condition is that all aspects must be considered important for the making of Europe. No sectors can be neglected. The monetary dimension, especially, should not be left apart.
Les conséquences macro-économiques et financières du krach
Authors: Cheval Jean 
Published: April 2013

The macroeconomlc and financial consequences of the crash
The stock market's crash occured in the boom of global activity, boom which was obvious in almost all countries. This growth's movement was specially strong in Japan, UK and USA. Two main factors generated this dynamism : the positive effects of the slump of oil prices and the outcome of the Louvre Agreement. This dynamics cannot be broken in the short term, because, unlike the financial events, the inertia of the real economy is a basic fact. This fact is strengthened by the weakness of the "wealth effect", even in the USA, and by the accomodating character of the monetary policies since the crash. The way is very narrow between the "ideal exit" (current trend) ans the set-off scenario (US recession). While the effects of the crash on real sphera are paradoxically not significant, the consequences for the financial sphera show, in any case, a "financial intermediation overcapacity" and prompt the professionnals to make some rationalization efforts.
