Authors: Tafazolian Saeed , Torres Fernando
Published: January 2018

Let 𝓧 be the nonsingular model of a plane curve of typeyn=f(x) over the finite fieldFof orderq2, wheref(x) is a separable polynomial of degree coprime ton. If the number ofF-rational points of 𝓧 attains the Hasse–Weil bound, then the condition thatndividesq+1 is equivalent to the solubility off(x) inF; see [20]. In this paper, we investigate this condition forf(x) =xℓ(xm+1).

Authors: Liao Kaili , Ge Jijiang , Zhang Guicai , Fu Lipei
Published: January 2018

Ultrasound has a wide range of applications in oil sands separation industry due to its green and nopolluting characteristics. The combined ultrasounds technology has been widely used in many industries by virtue of the synergistic effect of cavitation effect; meanwhile, dual-frequency ultrasounds have been reported being used in lotion oil sands technology. Based on this idea, this study focuses on the application of multiple frequency ultrasounds in oil sands separation, and a comparative study has been conducted between the combined ultrasounds systems with the difference in the number of the ultrasound. The results show that the oil production rate of the samples treated by the lotion of sodium dodecyl benzene sulfonate (SDBS) and assisted by multiple frequency ultrasounds (96%) is significantly higher than that of the single frequency ultrasound (76%); the bigger the number of the ultrasound participating in the combination is, the higher the oil production rate of the oil sands is; the lower the frequency of the ultrasounds employed in the combined system is, the higher the oil production rate is. The optimum treating conditions for tri-frequency ultrasounds assisted technology are as follow: the treating time is 10-15 min, the treating temperature is 20-30°C, the concentration of surfactant in the lotion is 1.5 g/l, and the mass ratio of the lotion to oil sands is 1.8. In short, the use of multiple frequency ultrasounds can improve the oil production rate of oil sands, reduce the energy consumption during the separation process, and reduce the environmental contamination; therefore, multiple frequency ultrasounds assisted oil sands separation technology is a promising technology for oil sands resources exploitation with high efficiency.

Arbeitshandeln und der digitale Wandel von kleinen und mittleren Unternehmen
Authors: Huchler Norbert , Rhein Philipp
Published: January 2018

Der Beitrag geht von der These aus, dass die technikgetriebenen Leitbilder des digitalen Wandels, wie sie im Zusammenhang der Vision „Industrie 4.0“ vertreten werden, die Potenziale des menschlichen Arbeitshandelns nicht bzw. nicht ausreichend berücksichtigen. Im Unterschied zu früheren Strategien der Technisierung, die auf die „menschenleere Fabrik“ zielten, werden zwar im Diskurs normative Markierungen zum Stellenwert des Menschen gesetzt, aber diese werden nicht funktional und empirisch untermauert, im Sinne der Leistung menschlichen Arbeitshandelns für Arbeitsergebnis und wirtschaftlichen Erfolg. Anhand einer empirischen Studie in produzierenden kleinen und mittleren Unternehmen wird exemplarisch gezeigt, welche funktionalen Leistungen menschliche Arbeitskraft erbringt, die durch digitale Technik zwar beeinträchtigt oder unterstützt, nicht aber ersetzt werden können. Aus den empirischen Ergebnissen werden zwei Schlüsse gezogen: Digitalisierungsleitbilder, die die funktionalen Leistungen menschlichen Arbeitshandelns nicht systematisch erfassen, sind insbesondere für kleine und mittlere Unternehmen dysfunktional. Und: Nicht die Digitalisierung als solche gefährdet menschliche Handlungsspielräume, vielmehr kann digitale Technik diese auch fördern; dazu kann und muss sie aber entsprechend gestaltet werden. Für ein entsprechendes Zusammenspiel von Mensch, Technik und Organisation in der digitalen Arbeit fehlen aktuell noch geeignete Konzepte und Lösungen.
Subjektive Aneignungspraktiken digitaler Technologien und die zugrunde liegenden Gerechtigkeitsansprüche der Beschäftigten
Authors: Walker Eva-Maria
Published: January 2018

Mit der Digitalisierung der Arbeitswelt wird die Frage nach einer humanen Gestaltung von Arbeit neu diskutiert. Der Beitrag zeigt anhand einer empirischen Fallstudie zur Implementierung eines digitalen Warenwirtschaftssystems („Shelvesfit“) in einem Handelskonzern, wie sich hierdurch Arbeitsinhalte verändern und ob – und wenn ja, wie – damit subjektive Ansprüche an „gute Arbeit“ verletzt werden. Als „gute Arbeit“ werden dabei jene Arbeitsbedingungen verstanden, die den Filialbeschäftigten in ihrer Selbsteinschätzung ein angemessenes Maß an Handlungsautonomie gewährleisten (das kann also auch heißen:keineHandlungsautonomie), um ihre Selbstansprüche an erfolgreiches Beraten und Verkaufen zu erfüllen. Die empirischen Befunde zeigen, dass die subjektiven Ansprüche der Beschäftigten an die Einführung der digitalen Technologie durchaus in Widerspruch geraten können mit den organisational intendierten Funktionen der Technologie, die Filialbeschäftigten sich die Technologie aber auf eine Art und Weise aneignen, dass sie das subjektiv als notwendig wahrgenommene Maß an professionellem Handlungsspielraum bewahren oder zurückgewinnen können, um in ihrer Wahrnehmung erfolgreich beraten und verkaufen zu können. Der Beitrag zeigt damit auch auf, wie eine kritische Arbeitsforschung in ihrer Analyse „guter Arbeit“ auch die subjektiven Ansprüche der Beschäftigten einbeziehen kann.
Comparison of hydrogen production in microalgae under autotrophic and mixotrophic media
Authors: Duangjan Kritsana , Nakkhunthod Watsamon , Pekkoh Jeeraporn , Pumas Chayakorn
Published: January 2018

Hydrogen is an alternative source of energy of considerable interest, because it is environmentally friendly. Biological hydrogen production processes involving green microalgae are of significant interest. However, until present only few microalgae genera have been studied and almost all of those studies have focused only on cultivation using mixotrophic or heterotrophic media, which are expensive, and can be easily contaminated. This study aimed to compare the potential of biohydrogen production from novel green microalgae under autotrophic and mixotrophic media. A total of ninety strains of six orders of green microalgae were investigated for their capabilities of hydrogen production. The results showed that eleven novel hydrogen-producing microalgae genera were found. The hydrogen production in each order was influenced by the medium. Moreover, several strains presented notable levels of autotrophic hydrogen production and performed at over twice of the mixotrophic medium. These results should be supportive information for the selection and cultivation of hydrogen-producing microalgae in further studies.
The Role of Innovation in Fostering Competitiveness and Economic Growth: Evidence from Developing Economies
Authors: Terzić Lejla
Published: January 2018

This paper deals with the essential features determining the role of innovation in developing economies by examining the structure of innovation measures. The economic growth and competitiveness of developing economies are powerfully connected to its innovation status. The purpose of this paper is to examine the significance of innovation in driving economic growth per capita and competitiveness in selected developing economies. In order to determine the interconnection among the variables of innovation, competitiveness, and growth, assorted methodological measurement instruments have been applied. The data were collected from both primary and secondary sources. The results suggest the importance of specific innovation dimensions for prospective economic growth in developing economies. The identical measures responsible for fragile innovation are associated to the low composite measures of innovation accomplishment. This demonstrates the enormous disparity concentrated in every innovation aspect over time, specifically in innovation output and enterprise performances between the developing economies and the EU–28 average measures. The research results indicate the usage of appropriate economic instruments in diminishing the problems that developing economies are currently dealing with.
Personal Finances vs. the Overall Economic Conditions: What Drives the New EU Member States’ Stock Markets?
Authors: Lolić Ivana , Sorić Petar , Čižmešija Mirjana
Published: January 2018

This paper analyses the leading characteristics of the Consumer Confidence Index (CCI) with respect to stock market returns for 11 New EU Member States. It proposes novel CCI weights by minimizing mean squared errors from regression forecasting equations, using CCI lags as regressors. With regards to the obtained “optimal” weights, the examined countries are grouped into micro‑ and macro‑oriented clusters. A strong shift is found in the weights due to the recent recession. The micro aspects (reflecting the wealth effect) severely lose their importance in the crisis, while the consumers’ macroeconomic sentiments grow in significance and constitute a separate transmission channel.
Analysis of the Polyphenols of Tobacco Using Pressurized Liquid Extraction (PLE) and Ultra Performance Liquid Chromatography With Electrospray Ionization – Tandem Mass Spectometric Detection (UPLC-ESI-MS/MS)
Authors: Shifflett John R. , Watson Leah , McNally Devin J. , Bezabeh Dawit Z.
Published: January 2018

Polyphenols are chemicals found in tobacco that are affected by the method used to cure the leaf and, as a result, can be useful in the characterization of tobacco products. The purpose of this work was to develop an analytical method to investigate the levels of six polyphenols found in tobacco leaves and tobacco products: 3-O-caffeoylquinic acid (chlorogenic acid), 4-O-caffeoylquinic acid (cryptochlorogenic acid), 5-O-caffeoylquinic acid (neochlorogenic acid), kaempferol 3-O-rutinoside (nicotiflorin), quercetin 3-O-rutinoside (rutin), and 6-methoxy-7-hydroxycoumarin (scopoletin). Extraction conditions for sample preparation using PLE and instrument conditions for analysis by UPLC-MS/MS were optimized and validated. Results from the analysis of 30 cured tobacco leaves are presented and discussed in the context of each curing method represented. Results from the analysis of various tobacco products are also presented and trends observed across product types are discussed in the context of the applicability of the validated method. Total polyphenol levels for flue-cured, Oriental, and air-cured leaves were determined to be in the ranges of 18–41 mg/g, 5–27 mg/g, and 0.5–3 mg/g respectively. Similarly, cigarette polyphenol levels were found in the range of 4–16 mg/g and cigar polyphenol levels were less than 1.5 mg/g. The trends observed in the results for the tobacco leaf samples are consistent with expectations regarding the fate of polyphenols under the conditions commonly used in curing procedures. The results for the tobacco products demonstrate that the validated method can be used to study polyphenol content in cigarettes and a variety of cigar types including pipe tobacco cigars.
Accuracy of the Smoking Questionnaire
Authors: Sponsiello-Wang Zheng , de La Bourdonnaye Guillaume , David Morgane , Lüdicke Frank , Weitkunat Rolf
Published: January 2018

The smoking questionnaire (SQ), a multidimensional questionnaire covering the major dimensions of cigarette smoking, was developed to address the heterogeneity in the assessment of smoking exposure. It consists of eight questions and can be completed within a few minutes. Test-retest reliability of the SQ and concurrent validity with the Behavior Risk Factor Surveillance System (BRFSS) 2011 questionnaire were examined in a clinical study conducted in adult US current menthol cigarette smokers. The SQ and the BRFSS were self-administrated twice before and after randomization with a 6-day interval. The inter-temporal analyses included current smokers aged 22 to 66 years who completed the SQ at both timepoints. The percent agreement of items and 95% confidence intervals were calculated for the comparisons between the two timepoints and between the SQ and the BRFSS questionnaire. To evaluate the feasibility of the SQ and to capture subjects’ opinions about the SQ, a meta-questionnaire was administrated. High test-retest reliability levels (percent agreement of > 70 to 100% between the two timepoints) were found for SQ smoking behavior items, in particular for items related to current smoking status, 100-cigarettes lifetime, regular smoking, age of initiation and preferred brand. Moderate (55% agreement) to high test-retest reliability (84% agreement) was found for daily consumption of manufactured cigarettes. The comparison between the SQ and the BRFSS 2011 showed a high concurrent validity (98 to 100% agreement). The SQ was completed on average in 3 to 4 min and was assessed as easy to use. The findings demonstrate that the SQ is reliable in smokers and a practical tool to assess smoking exposure in clinical studies.

Authors: Kirişci Murat
Published: January 2018

Fuzzy sets are the cornerstone of a non-additive uncertainty theory, namely possibility theory, and of a versatile tool for both linguistic and numerical modeling. Fuzzy sets have be- come popular in every branch of mathematics such as analysis, topology, algebra, applied mathematics etc. Thus fuzzy sets triggered the creation of a wide range of research topics in all areas of science in a short time. In this paper, we use the triangular fuzzy numbers for matrix domains of sequence spaces with infinite matrices. We construct the new space with triangular fuzzy numbers and investigate to structural, topological and algebraic properties of these spaces.

Ultrasonographic Examination of Some Vessels in Dogs and the Characteristics of Blood Flow in These Vessels
Authors: Figurová M. , Kulinová V.
Published: January 2018

The examination by Doppler ultrasonography provides haemodynamic information about blood flow velocity in a respective vessel. It specifies high- and lowresistance flow patterns. The aim of our study was to record the flow in a. carotis communis, a. femoralis and aa. renales in 16 adult clinically healthy dogs of small and medium size; characterize the types of vessels and also determine the pulsatility index (PI) and the resistive index (RI) of these vessels. The a. femoralis is a high-resistance vessel with a pronounced three-peak waveform. The aa. renales gives a typical picture of a low-resistance flow pattern. The characteristics of a. carotis communis involves different images of its branches a. carotis interna and a. carotis externa. In the investigated groups we observed a medium degree of pulsatility (atypical highresistance flow pattern with an absence of reverse flow). The mean measured values of indices for a. carotis communis were: left side PI 1.824 and RI 0.742; right side PI 1.891 and RI 0.746, and for aa. renales: PI 1.366 ± 0.04 and RI 0.684 ± 0.05.
Current state of art of satellite altimetry

Published: January 2018

One of the fundamental problems of modern geodesy is precise defi nition of the gravitational fi eld and its changes in time. This is essential in positioning and navigation, geophysics, geodynamics, oceanography and other sciences related to the climate and Earth’s environment. One of the major sources of gravity data is satellite altimetry that provides gravity data with almost 75% surface of the Earth. Satellite altimetry also provides data to study local, regional and global geophysical processes, the geoid model in the areas of oceans and seas. This technique can be successfully used to study the ocean mean dynamic topography. The results of the investigations and possible products of altimetry will provide a good material for the GGOS (Global Geodetic Observing System) and institutions of IAS (International Altimetry Service). This paper presents the achievements in satellite altimetry in all the above disciplines obtained in the last years. First very shorly basic concept of satellite altimetry is given. In order to obtain the highest accuracy on range measurements over the ocean improved of altimetry waveforms performed on the ground is described. Next, signifi cant improvements of sea and ocean gravity anomalies models developed presently is shown. Study of sea level and its extremes examined, around European and Australian coasts using tide gauges data and satellite altimetry measurements were described. Then investigations of the phenomenon of the ocean tides, calibration of altimeters, studies of rivers and ice-sheets in the last years are given.

Stimuli of Collaboration in Product Development: A Case Study in a Project Manufacturing Company
Authors: Jääskeläinen Aki , Heikkilä Jussi , Hiidensalo Anna , Thitz Otto
Published: January 2018

There is already a wide acceptance on the importance of involving supplier and customer companies in product development. Decent understanding prevails on the relationship-oriented approach to product development including various collaboration forms. However, there is less research on the factors explaining the decision of attending to joint product development. In addition, less studies have examined the integrated role of both suppliers and customers in product development initiatives. This study searches answers to the following research questions: 1. What is the role of different actors in product development initiatives? 2. What factors motivate suppliers and customers to participate in product development? The research is carried out as an in-depth qualitative single case study in a large project manufacturing company. It takes the perspective of a focal company striving for product improvements. The first part of the empirical study consists of 15 semi-structured interviews. The second part includes two discursive workshops and builds upon the results of the interviews. This study contributes to the existing research by explaining the challenges and conditions facilitating joint product development with supplier and purchaser companies. The results highlight the role of customers in improving the effectiveness of product development. As a practical contribution, the paper reports the application of workshop method as a facilitator of collaboration between supplier, purchaser (focal company) and customer companies.
A Dual Perspective of Value in a Bundle of Product and Service
Authors: Safarpour Niusha , Sillanpää Ilkka
Published: January 2018

Focusing on value creation in marketing has always been the key to success for companies. As a result, the definition, analysis and communication of value has gained importance. Companies are making an attempt to make a value proposition that is not only lucrative for the customer, but also has great returns for the company itself. Although this might sound simple on paper, since it is the basis for business logic, it is much more complicated in real life situations. With the service elements in the offering and the emergence of technologies such as smart and connected phenomenon, the business models become more innovative and more complexity is added to the analysis of value.

The objective of this paper is to introduce a method for the dual perspective of value in a bundle of product and service in a smart and connected context. This method draws from the customer value and customer lifetime value concepts to offer an all-inclusive study on value. This assists companies in crafting an appealing value proposition in a cost-saving offering for a client that offers value to the company over its lifetime. This study specifically deals with the state of the arts smart and connected phenomenon and provides a view on how value works in that context.

The framework created through this study serves to help the company choose a client that is of most value to the firm over the time of their cooperation. It then leads the company towards a better fabrication of the offering that is not only an attractive proposition to the client but also for the company. It gives a close insight onto where the benefit comes from and how a smart and connected bundle of products, services and relationships must be put together for maximum results in the modern age.
A Turning Point in the Translation of Shakespeare into Catalan: The Case of Josep M. De Sagarra’s Macbeth
Authors: Palomo Berjaga Vanessa
Published: January 2018

Josep Maria de Sagarra translated twenty-eight of Shakespeare’s plays into Catalan in the early forties, at a time when Catalan language and culture were suffering severe repression due to Franco’s regime. The manuscript of Macbeth by Sagarra is from 1942; and the first edition (an impressive hard-bound clandestine edition) is from 1946 or 1947. Before his translation, there were three other Catalan translations of Macbeth, produced by Cebrià Montoliu (1907), Diego Ruiz (1908) and Cèsar August Jordana (1928). The main purpose of this article is to show that Sagarra’s translations marked a turning point regarding the translation of Shakespeare’s works in Catalan culture. This is done by reflecting on both cultural and personal circumstances that led Sagarra to translate Shakespeare and by comparing Sagarra’s translation of Macbeth with the other three from the first half of the twentieth century.
Biosorption of lead ions by cyanobacteria Spirulina platensis: kinetics, equilibrium and thermodynamic study
Authors: Zinicovscaia Inga , Yushin Nikita , Rodlovskaya Elena , Kamanina Inna
Published: January 2018

The potential use of dry Spirulina platensis biomass to remove lead ions from aqueous solution was investigated. Effects of various parameters such as contact time, temperature, dosage of biosorbent, initial pH, and initial concentration of lead were investigated in the batch adsorption mode. The highest lead removal of 5.7 mg/g was obtained at pH 5, biomass dosage of 0.5 g, initial lead concentration of 60 mg/L. The Langmuir and Freundlich models fit the experimental data (R2 > 0.99), while the kinetic data was best described using the pseudo second-order kinetic model (R2 > 0.99). FTIR spectra indicated that the metal removal takes place through binding to OH, C=O and P=O groups. Lead was efficiently recovered from biomass by mineral acids, while using CH3COOH and NaOH as eluents the biomass maintained high biosorption capacity during three cycles. This study demonstrates the potential of using Spirulina platensis as biosorbent to remove lead from industrial wastewater.

Balthasar Hubmaier: The Theologian of the Anabaptists. Nikolsburg and Catechetical Instruction: A Labor ofLove
Authors: Graffagnino Jason J.
Published: January 2018

Balthasar Hubmaier is often called ‘the theologian of the Anabaptists’ for he was the only early Anabaptist leader with an earned doctorate. The former Catholic priest embraced the reforming thought of Erasmus, Zwingli, and eventually Zwingli’s former pupils (the Anabaptists) and led the Moravian city of Nikolsburg to become a bastion of Anabaptist thought and practice. The multi-dimensional religious landscape both afforded Hubmaier the opportunity and compelled him to author the first Anabaptist catechism. Through the work, Hubmaier articulated a clear and succinct portrayal of Anabaptist theology and ecclesiology summed up in the Erasmian tenet of the love of God and neighbor.
Effect of textural and chemical characteristics of activated carbons on phenol adsorption in aqueous solutions
Authors: Vargas Diana P. , Giraldo Liliana , Moreno-Piraján Juan Carlos
Published: January 2018

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

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

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

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.

Among the criteria for determining the stages, there were socio-political, socio-economic, organizational and pedagogical factors that led to the change of subjects, goals, objectives, content, principles, forms, methods of organizing adult learning in Poland in the 20th century. The historical and pedagogical features of each stage are shown, the influence of historical events on the formation and development of adult education in Poland is taken into account and analyzed. In accordance with each stage, the leading forms and methods of adult learning are have been determined. The peculiarities of the activity of adult learning institutions at all stages have been demonstrated. The disadvantages of the adult learning system, as well as the difficulties of its development, have been identified.

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.

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.

Published: January 2018

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.
