Authors: Vargas Diana P. , Giraldo Liliana , Moreno-Piraján Juan Carlos 
Published: January 2018

Abstract
The effect of textural and chemical properties such as: surface area, pore volume and chemical groups content of the granular activated carbon and monoliths on phenol adsorption in aqueous solutions was studied. Granular activated carbon and monolith samples were produced by chemical activation. They were characterized by using N2 adsorption at 77 K, CO2 adsorption at 273 K, Boehm Titrations and immersion calorimetry in phenol solutions. Microporous materials with different pore size distribution, surface area between 516 and 1685 m2 g−1 and pore volumes between 0.24 and 0.58 cm3 g−1 were obtained. Phenol adsorption capacity of the activated carbon materials increased with increasing BET surface area and pore volume, and is favored by their surface functional groups that act as electron donors. Phenol adsorption capacities are in ranged between 73.5 and 389.4 mg · g−1.
Immigration and Federalism in Canada: beyond Quebec Exceptionalism?
Authors: Strazzari Davide 
Published: January 2018

Abstract
The paper focuses on Canadian Provinces’ role in migrant selection. After an asymmetric approach, that benefited only Quebec, the federal government granted devolutionary powers in migrant selection to the other Provinces as well, moving towards de facto asymmetry. This process has proved to be successful over the years, but recently the federal government has reacted, recentralizing some aspects of immigration policy. This does not apply to Quebec.
This policy change may suggest that, although immigration federalism may be grounded on reasons other than the need to accommodate linguistic or ethnic claims, it remains the case that the former are “weaker” than the latter, and are more subject to pressure from the central government.
This is also confirmed by looking at the mechanisms through which intergovernmental agreements have been translated into law. Unlike the Quebec case, immigration’s devolution in relation to the other Provinces has occurred through administrative delegation of powers from the federal government. This permits the federal government to exercise some form of political pressure in order to realign the Provinces’ discretionary choices.
The Spanish vision of Canada’s Clarity Act: from idealization to myth
Authors: Caro Francisco Javier Romero 
Published: January 2018

Abstract
Since it was passed, the Clarity Act has been at the core of any secessionist debate in Canada and abroad. Although contested at home, the Clarity Act has earned worldwide prestige as the democratic standard that must be observed when a secessionist debate arises. In the last fifteen years Spain has experienced successive debates about the need to establish a mechanism of popular consultation to address secessionist claims in the Basque Country and Catalonia. Most political actors in favour of such consultations have expressed their will to import the Canadian Clarity Act as a tool to settle disputes on how to conduct a referendum. However, this deification of the Canadian example is, for the most part, based on a misreading of the Secession Reference, only taking into account certain passages while ignoring others. The emphasis tends to be made on the quantitative clear majority test, disregarding other factors. Hence, the aim of this paper is to study the causes of this deification of the Clarity Act in Spain, and its influence on the treatment of secessionist claims that the country is currently experiencing.
Comparative Pedagogical Studies on Models of Education Systems Management in the EU and Ukraine
Authors: Desiatov Tymofii 
Published: January 2018

Abstract
The article highlights the peculiarities of models of education systems management in the EU and Ukraine. It has been proved that effectiveness of the education process is determined by managerial culture, which characterizes a manager’s professional image. Special attention has been paid to finding the right balance between centralization and decentralization, national goals and regional or local interests. It has been emphasized that this balance should take into account the features of each country, region. It has been found out that centralized education management systems in some countries and decentralized ones in others are preserved due to specifics of the national traditions. It has been revealed that these two models of management have tendencies for convergence. The relationship between the model of education management and a teacher’s pedagogical style has been investigated. It has been emphasized that a managerial component should be transformed into professional and personal qualities. It has been stated that education managers’ quality is considered to be a priority for the countries-participants of the Bologna process, including Ukraine, as it is taken into account as a leading condition for establishing trust, correlation, mobility, comparability and attractiveness. It has been noted that education managers’ training is associated with a complex of direct and remote psychological and pedagogical problems arising under the influence of scientific and technological transformations: a person’s employment, their intellectual development, biophysical state. It has been revealed that the management model development does not correspond to the level of the management object development in all EU countries. In this context, the fact should be taken into account that in the EU countries there are processes of transformation of national thinking in continental one, which somehow diminishes the traditional cult of the nation.

Published: January 2018

Abstract
Modeling of water flow in multi-channel river system in the Narew National Park. Anastomosing rivers constitute a rare example of multi-channel systems, which used to be very common before the agricultural and industrial development. Presently few of them remain worldwide and the only example in Poland is the Upper River Narew within Narew National Park. Although hydraulic modeling using one-dimensional models is commonly used to describe water flow in rivers, for multi-channel rivers problem is more complicated. For this type of rivers it is expected that the feedback between process of plants growth (expressed by Manning’s coefficient) and distribution of flow in anabranches is high. However, assignment procedure on roughness coefficients in splitting and rejoining channels is laborious and difficult. Therefore, for efficient water flow modeling in multi-channel systems a stand-alone hydraulic model equipped with automatic optimization procedure was developed. Optimization and validation stages, based on field measurements data of discharge and water levels, indicated that the model accurately simulates water flow in multi-channel system.

Abstract
The overconsolidation ratio of eemian gyttja determination. The overconsolidation ratio is an important parameter that determines the value of stress history exerted in the past on the subsoil in the geotechnical engineering. Overconsolidation ratio (OCR) is one of the main criteria conditioning soil behavior and characteristics. To know the relation between geological background, history and mechanical behavior of the soil, aims a knowledge that can help engineers who often have to predict soil behavior based upon the soil geological history and a geotechnical data. In order to evaluate the overconsolidation ratio of eemian gyttja, it is necessary to restore this soft soil as much as possible to the in situ conditions. The eemian gyttja is an organic soft soil from the “Zoliborz channel” located in Warsaw. These soils are used as a base construction in the foundation engineering. In practical geotechnical engineering, evaluation of stress history is based on the overconsolidation ratio. The overconsolidation ratio is one of the basic parameters for the geotechnical design of the structure. Determination of this parameter using for example dilatometer tests, is usually based on empirical formulas which were established in different countries. Therefore, regional geotechnical conditions could have substantially affected on the empirical relationships. The laboratory tests are used to determinate the preconsolidation pressure and then the overconsolidation ratio. The laboratory tests were made in the automatic oedometer and the in situ tests were carried out on the dilatometer test (DMT). The paper presents results of determination the overconsolidation ratio of eemian gyttja from the laboratory and in situ tests. The studies have shown that the values of the overconsolidation ratio determination from the laboratory tests are a little higher than determination from the in situ tests.

Abstract
A series of novel functionalized mesoporous silica-based materials with well-defined pore diameters, surface functionalization and surface morphology is synthesized by co-condensation or grafting techniques and characterized by solid-state NMR spectroscopy, DNP enhanced solid state-NMR and thermodynamic techniques. These materials are employed as host-systems for small-guest molecules like water, small alcohols, carbonic acids, small aromatic molecules, binary mixtures and others. The phase-behavior of these confined guests is studied by combinations of one dimensional solid-state NMR techniques (1H MAS, 2H-line shape analysis, 13C CPMAS) and two-dimensional correlation experiments like 1H-29Si- solid-state HETCOR.

AbstractHydraulic interconnection of Jomblangan cave (Petung) with other caves and water discharges in Gunungkidul karst area has been investigated using tracer techniques and variationof stable isotopes and hydrochemical data interpretation from water samples near the cave. Many studies related to the interconnections of underground rivers around Gunungkidul Karst area have been conducted, most of them, however, focused on the area around Bribin and Seropan caves. This is because of the development activites of microhydro turbines to lift the water from underground river were still focused around Bribin and Seropan caves. Petung cave, located in the north of Bribin and Seropan caves, was believed to be one of the caves at the upstream river system of Bribin and Seropan, however, there is no evidence yet of the hydraulic interconnection between Petung cave with either Bribin or Seropan caves. The results of tracer technique at the current study showed that there was no hydraulic interconnection between Petung cave with either Bribin and Seropan caves.On the other hand, the study showed an indication of a direct flow from Petung cave to Sriti and Beton springs. The travel times from Petung to Sriti and Beton springs were found to be around 2 and 10 hours, respectively. This finding is also in agreement with the results of chemical and stable isotopes analysis from the research location. AbstrakPenelitian keterhubungan Gua Jomblangan (Petung) dengan gua lainnya dan keluaran air di sekitar daerah karst Gunungkidul telah dilakukan dengan menggunakan teknik perunut dan variasi kandungan isotop stabil serta hidrokimia sampel air di sekitar gua. Penelitian yang berkaitan dengan keterhubungan antara sistim aliran bawah tanah di sekitar daerah karst Gunungkidul telah banyak dilakukan, namun sebagian besar dari penelitian tersebut hanya berpusat pada gua di sekitar Bribin dan Seropan. Hal ini terjadi karena kegiatan pembangunan turbin-turbin mikrohidro untuk mengangkat air dari sungai bawah permukaan tanah masih terfokus di daerah gua Bribin dan Seropan. Gua Petung, yang berada di sebelah utara gua Bribin dan Seropan, dipercaya merupakan salah satu gua yang berada di hulu sistim sungai bawah tanah Bribin dan Seropan, namun, sampai sekarang belum ada bukti keterhubungan hidrolika antara gua Petung dengan gua Bribin maupun dengan gua Seropan.Hasil uji perunut dalam penelitian ini menunjukkan bahwa aliran air bawah tanah di gua Petung tidak berhubungan langsung dengan aliran bawah tanah di gua Bribin maupun di gua Seropan. Sebaliknya, hasil penelitian ini menunjukkan adanya aliran langsung dari gua Petung ke mata air Sriti dan Beton. Waktu tempuh yang dibutuhkan dari gua Petung ke mata air Sriti adalah sekitar 2 jam dan ke mata air Beton adalah sekitar 10 jam. Temuan ini sangat bersesuaian dengan hasil analisis kimia air dan isotop stabil dari lokasi penelitian.
