Opis:
Reliquefaction technologies are being currently applied on board liquefied natural gas (LNG) carriers on the basis of economic criteria and energy efficiency. A variety of reliquefaction techniques have been developed so far during the last decade. Nevertheless, technology enhancement continues being a research area of interest. In this article the different technologies applied to the reliquefaction of the boil-off gas (BOG) on LNG carriers have been described, analysed and discussed, contributing to highlight the process and operation characteristics as well as selection plant criteria. Finally, a comparison of the different reliquefaction plants, considering their capacities and efficiencies as well as other technical data of interest has been carried out.

Opis:
The relation between the density of states at the Fermi level and the sign of the indirect coupling in metallic systems is revisited in the framework of a simple model recently outlined by the authors. It is shown that high density of states tends to favor ferromagnetic structures. Some examples which support this idea are indicated. Finally we develop a phenomenological explanation for the antiferromagnetic → ferromagnetic transition induced by heating equiatomic FeRh. The transition is analysed in terms of the increase in the density of states produced by the giant volume expansion associated with the ferromagnetic phase.

Opis:
A Research Object (RO) is defined as a semantically rich aggregation of resources that bundles together essential information relating to experiments and investigations. This information is not limited merely to the data used and the methods employed to produce and analyze such data, but it may also include the people involved in the investigation as well as other important metadata that describe the characteristics, inter-dependencies, context and dynamics of the aggregated resources. As such, a research object can encapsulate scientific knowledge and provide a mechanism for sharing and discovering assets of reusable research and scientific knowledge within and across relevant communities, and in a way that supports reliability and reproducibility of investigation results. While there are no pre-defined constraints related to the type of resources a research object can contain, the following usually apply in the context of scientific research: data used and results produced; methods employed to produce and analyze data; scientific workflows implementing such methods; provenance and settings; people involved in the investigation; annotations about these resources, which are essential to the understanding and interpretation of the scientific outcomes captured by a research object. The example research object contains a workflow, input data and results, along with a paper that presents the results and links to the investigators responsible. Annotations on each of the resources (and on the research object itself) provide additional information and characterize, e.g. the provenance of the results. Therefore, exploitation of the RO model should be considered as a way to provide additional reliability and reproducibility of the research. The concept of the RO was introduced to the environment created in the EVER-EST project in the form of Virtual Research Environment (VRE). a group of Earth Scientists, who are observing, analyzing and modeling processes that take place on land and see, was examined against their needs and expectations about the possible improvements in their scientific work. The results show that scientist expectations are focused on knowledge sharing and reuse, and new forms of scholarly communications beyond pdf articles as supporting tools of knowledge cross-fertilization between their members. The Research Object concept seems a natural answer for these needs. However, the model, in order to be sufficient and usable, must become a part of the working environment and needs to be integrated with the actual tools. Therefore, great efforts have been undertaken to create a generic, technical solution – VRE , which implements the expected functionalities. In this article we present a concept of the VRE as a tool that takes advantage of the Research Object model in order to integrate and simplify the information exchange, as well as persist, share and discover assets of the reusable research. Moreover, we are presenting example scenarios of the VRE usage in the four different Earth Science domains.

Opis:
The issue concerns the barriers limiting the process of cross-border cooperation (CBC) in Euroregions. There are two identified kinds of barriers coming out from the cross-border environment and the specific CBC circumstances in Euroregions. These barriers are identified and analysed with reference to the strategic goals of Cieszyn Silesia Euroregion, located on the Polish-Czech border. The goal of this paper is to point out the possible ways to limit the key barriers hindering the achievement of Euroregion goals, thanks to the commitment of the three key CBC stakeholders. The results of the research are analysed in comparison with other research concerning EUROACE Euroregion, located between the Portuguese and Spanish territories. Research shows that in both Euroregions similar ‘external’ barriers to the development of cross-border cooperation are identified, which are characteristics of peripheral regions, distant from national and regional decision centres. At the same time, the study identified ‘internal’ barriers to the development of cross-border cooperation, which most strongly affect the social objectives of cooperation and can be reduced at the local level by a skilful policy of local governments that should create the development of Euroregions and mobilize non-governmental organizations and entrepreneurs for cooperation.
Kwestia dotyczy barier ograniczających proces współpracy transgranicznej (CBC) w euroregionach. Istnieją dwa zidentyfikowane rodzaje barier wychodzących ze środowiska transgranicznego oraz szczególne okoliczności związane z CBC w euroregionach. Bariery te są identyfikowane i analizowane w odniesieniu do celów strategicznych Euroregionu Śląsk Cieszyński, położonego na granicy polsko-czeskiej. Celem tego artykułu jest wskazanie możliwych sposobów ograniczenia kluczowych barier utrudniających osiągnięcie celów euroregionu, dzięki zaangażowaniu trzech kluczowych interesariuszy CBC. Wyniki badań są analizowane w porównaniu z innymi badaniami dotyczącymi Euroregionu EUROACE, zlokalizowanego między regionami portugalskimi i hiszpańskimi. Badania pokazują, że w obu euroregionach zidentyfikowano podobne "zewnętrzne" bariery rozwoju współpracy transgranicznej, które są cechami regionów peryferyjnych, odległych od krajowych i regionalnych ośrodków decyzyjnych. Jednocześnie w badaniu zidentyfikowano "wewnętrzne" bariery rozwoju współpracy transgranicznej, które najsilniej wpływają na społeczne cele współpracy i mogą zostać zredukowane na poziomie lokalnym dzięki umiejętnej polityce samorządów lokalnych, które powinny przyczynić się do rozwoju Euroregionów i zmobilizować organizacje pozarządowe i przedsiębiorców do współpracy.

Opis:
In this article, we point out the need to base the process of designing buildings and architectural and urban spaces on criteria that take into account the gender perspective. As a conceptual framework for developing such standards serves the methodology proposed by Bernard Tschumi,1 referring to “theory” as a “practice” and the concept of care and corresponding values derived from feminist ethics of care. In his text “Event-Cities 3” (Tschumi, 2005), Tschumi claims that “theory is a practice of concepts.” In the present text, this is particularly understood as a need and way to redefine/re-construct the content...

Opis:
The grid method is the most widely used technique for measurement-based noise assessment, and indeed is part of the ISO 1996-2 standard. Nevertheless it has certain disadvantages. The present work is an analysis of the grid method for evaluating noise, firstly in the city of C´aceres and, secondly in two other smaller towns. Using as reference a 200 metre grid study, a study was made of the effect of varying the size and form of the grid on the city’s overall noise value, the percentage of data found to lie above some reference thresholds, and the noise value assigned to a certain zone of the city. The ISO 1996 recommendations of the necessity of new sampling points and the method’s predictive capacity for these new measurements were also analyzed.

The results of the measurements of temperature dependence of the electrical resistivity ρ(T), thermal expansion L(T) and susceptibility χ(T) on single crystal DyNi$\text{}_{5}$ in the temperature range 4.2-300 K are reported. The maximum in ρ(T) at T$\text{}_{N}$=12.2 K was observed which corresponds to the transition to antiferromagnetically ordered state. Taking into account the Bloch-Grüneisen formula for electron-phonon contribution ρ$\text{}_{ph}$(T) to ρ(T) the anisotropic magnetic contribution ρ$\text{}_{mag}$(T) was determined. We also observed the anisotropic behaviour of L(T) at low temperatures.

Opis:
The olive tree is represented in Tunisia by two varieties: var. sylvestris (wild olive trees) and var. europaea (cultivated olive trees including diverse cultivars). Seed (stone) size and shape analysis may provide the basis for relationships between varieties and cultivars as well as to study the responses to environmental conditions. A semi-automated method of image analysis allows to obtain data related with magnitudes descriptive of stone size and shape and to compare between wild and cultivated olives. Also, the effect of bioclimate on size and shape was analyzed in some cultivars. Stone size and shape presents high variability. In cultivated trees stones are larger. Mean seed image area is 0.38 and 0.75 cm² for wild and cultivated plants respectively. Roundness and circularity were compared as to their potential to define seed shape. Mean values were higher for circularity, but roundness is more variable reaching higher values in some individuals and varieties. Roundness is more useful to compare seed shape variations. In addition, climate factors affect the stone characteristics in cultivars; those of sub-humid region having larger stones. Phenotypic parameters of stone are discriminating parameters for the analysis of intra-specific, intra-varieties and intra-cultivars variability in Olea europaea.

Opis:
Previous studies concerning the categorisation method have been based on short daytime measure- ments. These studies demonstrated urban-noise stratification in the daytime. Nevertheless, legislation and standards refer to noise estimation throughout the day. This paper presents the first attempt to apply the categorisation method to indicators obtained through long-term measurements. The study was conducted in Plasencia, Extremadura (Spain) which has approximately 41,500 inhabitants. First, we conducted a stratification of the roads using the categorisation method. Second, long-term measurements (approxi- mately one week) were conducted at different sampling locations across different categories of streets. The results were analysed by category. Moreover, the profile of the noise-level variation was analysed during the day. The results revealed a stratification of sound levels measured across the different categories. Furthermore, we found health risks due to the noise levels in this town. Short-term measurements were also conducted to complete the categorisation method suitability analysis.

Opis:
Due to the problem that represents the accelerated production of waste from the consumption of polyethylene terephthalate (PET), it becomes necessary to look for alternative solutions; chemical recycling is a suitable method for conversion into a material with potential application in concrete additive, such as unsaturated polyester resins; with the above improvements and conservation of non-renewable raw materials can reduce the environmental impact. This investigation was focused on obtaining the synthesis of a polymeric resin by the method of glycolysis, and their characterization by Infrared Spectroscopy (FT-IR); the results show that the recycled materials (PET and its processing) are similar to reagents made from primary materials so that it is considered feasible to use in the intended application.

Opis:
The objective of this paper is to demonstrate a novel signal processing for detection, identification and flaw sizing of structural damage using ultrasonic testing with Electromagnetic Acoustic Transducers (EMATs). Damage detection involves the recognition of a defect that exists within a structure. Damage location is the identification of the geometric position of the defect. Defect classification is the cluster of the damage type into multiple damage scenarios. In the absence of external interferences, a good measure of detectability of a flaw is its signal-to-noise ratio (SNR). Although the SNR depends on various parameters such as electronics used, material properties, e.g. homogeneity and damping, and flaw size, it can be improved using advanced signal processing. The main scientific novelties presented in this paper focus on filtering signal noise through advanced digital signal processing; incorporating wavelet transforms for image and signal representation enhancements; investigating multi-parametric analysis for noise identification and defect classification; studying attenuation curves properties for defect localisation improvement and flaw sizing and location algorithm development.
Celem niniejszego artykułu jest omówienie nowatorskiego sposobu przetwarzania sygnałów w celu wykrywania, identyfikacji i oceny uszkodzeń strukturalnych przy użyciu ultrasonograficznych testów za pomocą elektromagnetycznych przetworników akustycznych (EMAT). Wykrywanie uszkodzeń polega na rozpoznaniu istniejących defektów wewnątrz danej struktury. Lokalizacja uszkodzeń sprowadza się do identyfikacji geometrycznego położenia defektu. Klasyfikacja defektu to klaster typu uszkodzenia w wielu scenariuszach uszkodzeń. W przypadku braku zewnętrznych zakłóceń, dobrym wskaźnikiem wykrywalności błędu jest stosunek sygnału do szumu (SNR). Pomimo tego, że SNR zależy od różnych parametrów, takich jak użyta elektronika, właściwości materiału, np. jednorodność i tłumienie, a także wielkość wady, wskaźnik ten można poprawić przy użyciu zaawansowanego przetwarzania sygnałów. Główne nowe zagadnienia naukowe przedstawione w niniejszym artykule skupiają się na filtrowaniu szumu sygnału za pomocą zaawansowanego przetwarzania sygnału cyfrowego, w tym wykorzystując transformaty falkowe w celu ulepszenia obrazu i sygnału; badanie analizy wieloparametrycznej w celu identyfikacji szumów i klasyfikacji defektów; badanie właściwości krzywych osłabiania w celu sprawniejszego wykrywania i oceny wad oraz rozwoju algorytmu lokalizacji.
