Published: May 2018

Turbojet engine is a complex technical object. It fulfils an important role in the civil and military aviation. Its undesired operation can lead to tragic accidents. Hence the large role takes the proper preparation for work and adequate regulation. The correctness of the engine work is tested periodically during ground tests. During the ground tests the responses to set engine control lever (DSS) shift is examined, thus means that the engine is examined from the "set point". During ground testing is not possible to reflect the impact of changing conditions during engine operation in flight so the engine is not tested on the noise signal. It turns out that it is the properties of the noise signal often have a decisive effect on the engine operation correctness and by that on the safety of the flight. Hence there is a need to develop methods to assess the state of the engine control signal from noise on the basis of standard ground test from the set point (delivered by the DSS).
Safety Culture and its Influence on Safety / Kultura Bezpieczeństwa I Jej Wpływ Na Bezpieczeństwo
Authors: Berg Heinz-Peter , Kopisch Christopher
Published: May 2018

Safety culture is a well-known concept in different industries worldwide, in particular in the nuclear field. Safety culture is recognized as an important factor in achieving high levels of safety performance. Although there is a wealth of information relating to safety culture, there is still no universal definition or model. Thus, the appropriate definition for the respective area such as nuclear, aviation or maritime has to be determined. However, the essence of safety culture is the ability and willingness of the organization to understand safety, hazards and means of preventing them as well as to act safely. Safety can only be achieved through the use of reliable structures, components, systems, and procedures as well as plant personnel committed to a strong safety culture.

A TYPOLOGICAL RARUM IN SOGDIAN: OVERT COMPLEMENTIZERS IN INDICATIVE ROOT CLAUSES
Authors: Franco Ludovico
Published: May 2018

The purpose of this work is to illustrate an extremely rare linguistic feature, namely the overt present of a root complementizer in assertive/indicative (i.e. unmarked) matrix clauses, of the Sogdian language, an Eastern Middle Iranian Language once spoken in a region located in the valley of rivers Zaravshan and Kashkadarya (roughly corresponding to the territory of modern day Uzbekistan and Tajikistan). This linguistic fact is very interesting because it represents an overt evidence of the principle of endocentricity inferred in the Generative tradition since the early 80s. In comparative perspective, this uncommon feature of the Sogdian language may be associated to the mechanism of para-hypotaxis, previously studied in many different Romance languages (e.g. Old French, Old Italian, Old Catalan) and recently discovered in other genetically unrelated languages (e.g. Swahili, Zamucoan languages)
SOME BERBER ETYMOLOGIES X
Authors: Takács Gábor
Published: May 2018

My series “Some Berber Etymologies” is to gradually reveal the still unknown immense Afro-Asiatic heritage in the Berber lexical stock. The first part with some miscellaneous Berber etymologies was published back in 1996. Recently, I continued the series according to initial root consonants1 in course of my research for the volumes of the Etymological Dictionary of Egyptian (abbreviated as EDE, Leiden, since 1999, Brill)2 with a much more extensive lexicographical apparatus on the cognate Afro- Asiatic daughter languages. As for the present part, it greatly exploits the results of my ongoing work for the the fourth volume of EDE (analyzining the Eg. lexical stock with initial n-). The present part contains etymologies of Berber roots with initial *n- followed by sibilants. The numeration of the entries continues that of the preceding parts of this series. In order to spare room, I quote those well-attested and widespread lexical roots that appear common Berber, only through a few illustrative examples. The underlying regular consonant correspondences between Berber vs. Afro-Asiatic agree with those established by the Russian team of I.M. Diakonoff and summarized by A.Ju. MILITAREV: (1991, 242-243).

Social capital as a determinant of business innovativeness / Kapitał społeczny jako czynnik determinujący innowacyjność przedsiębiorstw
Authors: Skawińska Eulalia , Zalewski Romuald
Published: May 2018

The problem of innovativeness and competitiveness of the Polish economy is rising to strategic importance in the new EU financial perspective for 2014-2020. It is strongly related to social capital. This paper contains the results of the research on the relationship between social capital and innovative companies and the existing barriers to the implementation of innovative functions by this capital in Greater Poland. The data used have come from independent studies carried out on two collectivities of managers. Each one was composed of about 150 participants. Surveyed managers have indicated medium and low ratings regarding the attributes of social capital of their own employees. These shortcomings of individual social capital have not been reduced in the expected network process of value-added relationships reflected in a higher group capital. Opinions of entrepreneurs on different forms of innovative potential of employees expressed in a five point rating scale have ranged from 3.82 to 2.47, and the average value stands at 2.97. Nevertheless, most companies have not undertaken any action to prepare and shape the pro-innovation attitude of its employees. Only a few companies have initiated or strengthened the knowledge and information management system, methods to motivate employees to submit innovative ideas or shaping the competences supporting innovative processes. In reflection on this problem we find the need to identify the causative factors that increase the potential for innovation and its efficiency by improving the level and structure of social capital in the future.

In the paper the author provides insight into core aspects of the destination competitiveness as well as marketing communication. Theoretical contributions) were expanded by the author’s surveys designed to feature the most effective channels for communicating with a potential customer, as well as to identify key message contents, and factors at the heart of making a travelling decision
Financing of SME using non-recourse factoring – legal, economic and tax aspects / Finansowanie małych i średnich przedsiębiorstw w postaci faktoringu pełnego aspekty prawne, ekonomiczne i podatkowe
Authors: Czternasty Waldemar , Mikołajczak Paweł
Published: May 2018

Specific character of SME determines a limited access to short-term capital which is essential for running the business. A financial tool which on one hand enables small entities to improve their financial liquidity and, on the other, to limit the risk connected to delays in settling the receivables, is non-recourse factoring. Both, its construction in the legal, tax and financial context, as well as the procedure of granting it by financial institutions make this instrument gain more and more popularity among the companies in Poland.

Real convergence of the European Union members states – evaluation attempt
Authors: Grzelak Aleksander , Kujaczyńska Marlena
Published: May 2018

The key aim of the article is to verify the hypothesis concerning convergence in the economic development of the EU member states, which is reflected in evening out differences in the economic development level of the EU member states. New member states develop faster than old member states. In the light of the presented results, economic convergence of the member states seems not to be homogenous. Thus, it can be provisionally stated that progress has been recorded as regards convergence of the member states economies, in particular since 2007, although it needs to be emphasised that differences between them are still significant.
Cereal Market before and after the Integration of Poland into the European Union. Dynamics of Supply and Demand Correlations / Rynek zbóż przed i po integracji Polski z Unią Europejską. Dynamika relacji popytowo-podażowych
Authors: Czakowski Dariusz
Published: May 2018

The purpose of this publication is to show some changes in supply and demand correlations on the cereal market after Poland’s accession into the European Union. To meet the above objective there were compared some data concerning the volume of domestic cereal production and its cereal species structure, foreign trade balance, domestic consumption and purchase price levels. The formation of the above mentioned items was analyzed for two periods. The first one covered the years 1995-2003 whereas the second one was from 2004 to 2012. This allowed us to make some interesting comparisons through the prism of Poland’s accession to the EU. Additionally, long time series increased their reliability. To study supply and demand correlations, there were applied various statistical methods including dynamic indexes, trend models, analyses of correlation and various regression. A comprehensive analysis of the gathered research material allowed us to answer the question about some quantitative and qualitative changes which took place on the cereal market after Poland’s accession to the EU.

Authors: Ghita Cornel , Scarlat Cezar , Santos José Freitas , Correia de Barros Antonio
Published: May 2018

The paper presents a study on business micro-location behaviour as well as corresponding factors of influence, conducted in two metropolitan areas, Bucharest-Ilfov (Romania) and Greater Porto (Portugal). By business micro-location we refer to a specific site such as a building or facility, accommodating a business within a small, compact geographical area (e.g. metropolitan area). At this geographical scale, the macroeconomic layer factors were excluded, applicable when discern between regions or countries. The factors derived from location theory and previous empirical studies were surveyed, completing a cross-sectional analysis in order to find out the specific weights of the location factors and preferences, by region and by industry. Based on already established firms’ feedback on location, the specific weights were granted by each industry to the main location factors, types of areas, and types of accommodation facilities. The authors also suggested a model to integrate these results into a Geographical Information System (GIS).

Generating Sub-nanometer Displacement Using Reduction Mechanism Consisting of Torsional Leaf Spring Hinges
Authors: Fukuda Makoto , Hayashi Masato , Marita Sintaro
Published: May 2018

Recent demand on the measurement resolution of precise positioning comes up to tens of picometers. Some distinguished researches have been performed to measure the displacement in picometer order, however, few of them can verify the measurement performance as available tools in industry. This is not only because the picometer displacement is not yet required for industrial use, but also due to the lack of standard tools to verify such precise displacement. We proposed a displacement reduction mechanism for generating precise displacement using torsional leaf spring hinges (TLSHs) that consist of four leaf springs arranged radially. It has been demonstrated that a prototype of the reduction mechanism was able to provide one-nanometer displacement with 1/1000 reduction rate by a piezoelectric actuator. In order to clarify the potential of the reduction mechanism, a displacement reduction table that can be mounted on AFM stage was newly developed using TLSHs. This paper describes the design of the reduction mechanism and the sub-nanometer displacement performance of the table obtained from its dynamic and static characteristics measured by displacement sensors and from the AFM images
RICHARD HOOKER’S WORRIES ABOUT THE MIND: THE PATH TO CERTAINTY
Authors: Almasy Rudolph P.
Published: May 2018

Focusing on two of Richard Hooker’s sermons, “Certaintie and Perpetuitie of Faith in the Elect” and “Learned Sermon of the Nature of Pride”, this essay explores Hooker’s worries about how the mind reacts to matters of religious doubt, curiosity, arrogance, and mental confusions. These worries of what enters the mind influence the search for what Hooker calls the certainty of adherence (faith) and the certainty of evidence (knowledge). Such worries, prompted by what Hooker sees as the mind’s frag- ileness in the face of religious experience and religious truth, lead Hooker in the sermons, as well as in his Ecclesiasticall Lawes, to a certain religious and rhetorical position which emphasizes the notion of approaching faith and knowledge in terms of simplicity or singleness. This approach, Hooker counsels, should lead the potentially confused mind, regardless of the certainty it seeks and of the influence of the Holy Spirit, toward the notion of surrender-to God or to the rhetor.
Dietary Sodium Intake and the Main Sources of Salt in the Diet of Young Adults in Latvia
Authors: Leite Gunta , Kunkulberga Daiga
Published: May 2018

Scientific studies have regularly confirmed that nowadays the salt consumption through food is too much, and its consumption has to be reduced. The aim of the study was to ascertain the amount of salt consumed per day by 18–35 year-old Latvians as well as to identify the main sources of salt in their diets. The following research methods were used in the study: questionnaire based on an example recommended by the World Health Organisation, sociological research method, bread baking tests, and logically constructive, and statistical research methods. The results of this research showed that the average intake of salt in the diet of 18–35 year-old Latvians was 7.1 g per day. Of all the respondents, 63% consumed more than the recommended 5 g of salt per day, and none of them consumed less than necessary to meet their physiological needs. The results showed that women consumed less salt than men — approximately 6 g per day, while men consumed 8.2 g of salt per day. The main sources of salt in the diet of 18–35 year old Latvians were cereals and cereal products, as well as meat and meat products. Among cereal products, the key source of salt was represented by bread and pastry.

Authors: Ozola Liene , Kampuse Solvita
Published: May 2018

The objective of this study was to examine the suitability of heat treatment methods on concentrations of bioactive compounds in pumpkin–guelder rose sauce. Berry hybrids 2--30--K, 2--45--K and variety ‘Krasnaya Grozdj’ were selected for further research. The juice of these fruits was used to create pumpkin–guelder rose sauce samples (experimental samples) where the pumpkin puree and guelder rose fruit juice ratio was 74.5 : 13.1. To all samples heat treatment under atmospheric conditions (traditional cooking) and vacuum cooking at 0.6 bar pressure at 85 °C and 0.2 bar pressure at 75 °C temperature was performed. These samples were compared with uncooked experimental samples. Sauce chemical evaluation showed better retention of vitamin C concentrations (per dry weight) for guelder rose variety ‘Krasnaya Grozdj’ sauces cooked at 0.2 bar pressure, compared to fresh samples. Samples that were prepared with vacuum cooking methods on average showed higher total phenol concentration, antiradical activity and total anthocyanins concentration than in control samples cooked under atmospheric conditions. These observations were consistent with reports in the literature on better preservation of bioactive compounds in plant-based products that are cooked under vacuum heat treatment at lower temperatures.

Authors: Vereş Monica , Babeş Aurel , Lacziko Szidonia
Published: May 2018

Background and aims: Gestational diabetes represents a form of diabetes diagnosed during pregnancy that is not clearly overt diabetes. In the last trimester of gestation the growth of fetoplacental unit takes place, thus maternal hyperglycemia will determine an increased transplacental passage, hyperinsulinemia and fetal macrosomia. The aim of our study was that o analyzing the effect of maternal glycemia from the last trimester of pregnancy over fetal weight. Material and method: We run an observational study on a group of 46 pregnant women taken into evidence from the first trimester of pregnancy, separated in two groups according to blood glucose determined in the third trimester (before birth): group I normoglycemic and group II with hyperglycemia (>92mg/dl). Results: The mean value of third trimester glycemia for the entire group was of 87.13±22.03. The mean value of the glycemia determined in the third trimester of pregnancy was higher in the second group (109.17 mg/dl) in comparison to the first group (74.,21 mg/dl). The ROC curve for third trimester glycemia as fetal macrosomia appreciation test has an AUC of 0.517. Conclusions: Glycemia determined in the last trimester of pregnancy cannot be used alone as the predictive factor for fetal macrosomia.
Are There Any Substantial Differences in the Anthropometric and Metabolic Profile Between Patients with Impaired Fasting Glycemia and Impaired Glucose Tolerance ?
Authors: Mihai Bogdan Mircea , Ungureanu Didona Anca , Petriş Antoniu Octavian , Lăcătuşu Cristina Mihaela
Published: May 2018

Background and Aims: Prediabetes, a category of incipient hyperglycemia that includes impaired fasting glycemia (IFG) and impaired glucose tolerance (IGT), has an increasing incidence in the modern world. We searched for differences in anthropometric and metabolic characteristics between subjects with isolated IFG and IFG+IGT. Material

and Methods: In our cross-sectional study, 154 subjects with IFG and IFG+IGT, without any other major pathologies, were analyzed. Anthropometric data, lipid profile, uric acid, insulin resistance indexes, adiponectin, leptin and leptin-to-adiponectin ratio were compared. Results: Only 122 subjects (64 with isolated IFG and 58 with IFG+IGT), without any other identifiable major disease, were included in the final analysis. Most characteristics of the two groups were similar, only minor differences in anthropometric data, biochemical profile and insulin resistance indexes being noted. Insulin resistance indexes were stronger associated with adiponectin in the group with isolated IFG and with leptin and leptin-to-adiponectin ratio in the IFG+IGT group. Conclusions: Our data suggest a similar anthropometric and metabolic profile in subjects with isolated IFG and with IFG+IGT. In isolated IFG, insulin resistance seems to correlate better with adiponectin, while in IFG+IGT it seems to associate mostly with leptin and derived parameters
The Role of Distubances of Phosphate Metabolism in Metabolic Syndrome
Authors: Stoian Marilena , Stoica Victor , Radulian Gabriela
Published: May 2018

Background and Aims: Metabolic syndrome represents a cluster of cardiovascular risk factors and reached epidemic proportions. It was hypothesized that disturbances in phosphate metabolism may represent a feature of the metabolic syndrome. The aim of the study was to investigate the relationship between phosphate levels and the presence of metabolic syndrome components, as well as the putative mechanism for reduced phosphate level in metabolic syndrome. Materials and Methods: We enrolled 155 subjects: 64 with metabolic syndrome and 91 controls. Biochemical parameters of the metabolic syndrome study population were compared with the healthy population. Results: Patients with metabolic syndrome showed significantly lower phosphate (46%) and magnesium levels compared with controls (22.7%) (p<0.001). Women showed significantly greater serum phosphate levels than men (3.32 mg/dl versus 3.18 mg/dl) (p<0.03). Serum magnesium levels did no differ significantly between men and women. Fractional phosphate excretion rates in patients with metabolic syndrome were similar with controls (10.1±10.2% vs 13.1±9.9%), as well as fractional magnesium excretion (3.1±1.6% vs 2.8±1.3%). Conclusions: Patients with metabolic syndrome show significantly lower phosphate and magnesium concentrations compared to controls. This reduction is likely to be attributed to internal redistribution of phosphate and is more pronounced as the number of components of metabolic syndrome increases
Wrist Circumference: An Independent Predictor of Both Insulin Resistance and Chronic Kidney Disease in an Elderly Population
Authors: Mitrea Adina , Soare Andreea , Popa Simona Georgiana , Tudor Mirela Nicoleta , Mota Maria , Pozzilli Paolo
Published: May 2018

Background and aim: It was recently reported that wrist circumference is associated with insulin resistance (IR) both in children and adults. We aimed to evaluate whether wrist circumference is a useful anthropometrical parameter for the evaluation of IR in an elderly population. Material and method: We performed a study on 40 subjects, 20 with type 2 diabetes (T2D) and 20 control subjects. IR was evaluated using the homeostasis model assessment of insulin resistance (HOMA-IR). We measured the following anthropometrical parameters: weight, height, waist circumference (WC), hip circumference, wrist circumference, waist to hip ratio (WHR), waist to height ratio (WHtR), body mass index (BMI) and body adiposity index (BAI). Results: We found statistically significant differences between the subjects with T2D and the control group for all the analyzed parameters. Statistically significant correlations between all the anthropometrical parameters and HOMA-IR were observed. However, only WC was an independent predictor of IR. Wrist circumference was the only parameter negatively correlated with the estimated glomerular filtration rate (eGFR). Furthermore, this measurement was an independent predictor of chronic kidney disease (CKD) in the studied subjects. Conclusion: Wrist circumference can be used in the general practice as a surrogate marker of IR in the elderly, being both easily determined and a cost-free method
Lantus solostar in real life medical practice
Authors: Florenţiu Ariel , Dima Ioana
Published: May 2018

Background and aims: The epidemic of diabetes mellitus has made the effective treatment of hyperglycemia a top priority. Maintaining near-normal glycemic levels has been demonstrated to have a beneficial effect on diabetes-specific complications. Insulin can decrease any level of elevated glycated hemoglobin. Insulin glargine (Lantus®) is a long-acting insulin analog with a favorable 24-h time-action profile, once daily administration and low risk of hypoglycemia used in type 1 and 2 diabetes. In Romania, real-life data about glycaemic control is lacking. Material and methods: We present results from a retrospective, open-label, non-randomised, registry trial in 2946 Romanian diabetes patients. The objective of the study was to assess the proportion of patients with appropriate glycaemic control after 3 to 6 months of glargine treatment. Results and conclusions: A little over one third of the patients had reached target glycated hemoglobin after 3-6 months of glargine treatment in both types of diabetes. In type 2 diabetes patients the glargine dose used was not high (0.33 UI/kg). Inadequate insulin titration is a possible cause for not reaching glycemic targets.

Published: May 2018

Background and Aims: The evaluation of preoperative status of diabetic chronic dialyzed patients consists in determining the preoperative risk factors and choosing the optimal surgery time to reduce further complications. Material and method: we conducted a retrospective study that included 156 chronic dialyzed subjects (diabetic and non-diabetic patients) undergoing surgical interventions, between 2010 and 2013. The incidence of preoperative parameters considered as risk factors (e.g.: cardiovascular, cerebrovascular or pulmonary diseases, anemia, nutritional and inflammatory status) was compared between the 2 groups of patients. Results: the diabetic group compared to the non-diabetic one presented a statistically significant higher value of the following variables: obesity (29.8% vs. 8%, p<0.05), ischemic cardiovascular disease (100% vs. 85.8%, p<0.05), congestive heart failure (100% vs. 79.7%, p<0.05), peripheral vascular disease (42.1% vs. 7%, p<0.05), stroke sequelae (12.28% vs. 3.03%) and elevated Creactive protein levels (4.01±5.4 vs. 6.34±10.28, p<0.05). There were no statistically significant differences between the 2 groups regarding: age, smoking status, hypertension, mean hemoglobin, serum albumin, and chronic lung diseases prevalence (p>0.05). Conclusions: considering the high prevalence of cardiovascular diseases in diabetic patients, the preoperative evaluation of dialyzed diabetic individuals should be performed thoroughly, emphasizing the diagnosis and staging of cardiovascular diseases, chronic lung diseases and nutritional status.

Published: May 2018

Autoimmune polyglandular syndromes are characterized by the association of two or more autoimmune diseases. They are classified into two major subtypes, each having its own characteristics. The autoimmune polyglandular syndrome type 2 is defined by the presence of at least two of the following diseases: Addison’s disease, type 1 diabetes mellitus and thyroid autoimmune disease. Other autoimmune diseases belonging to the autoimmune polyglandular syndrome type 2 are: primary hypogonadism, myasthenia gravis, celiac disease, pernicious anemia, alopecia, vitiligo. We are going to present the case of a patient, aged 40, with diabetes mellitus (probably latent autoimmune diabetes of the adult), chronic autoimmune thyroiditis and celiac disease.
Lifelong Learners Influencing Organizational Change
Authors: Caves Lonzo
Published: May 2018

Organizational change occurs in every organization that deals with growth and transition. Organizational leaders develop a commitment to lifelong learning throughout their careers. As the organizational leader grows, the organization in which they lead grows as well. Organizational leaders are characterized by how they develop their strategic plan that will influence change. Discipline is essential to the development of a leader influencing organizational change. Organizational leaders create psychological contracts with employees to build trust, confidence, and business relationships. Psychological contracts motivate employees intrinsically, and in ways that go beyond the confines of the physical contract signed between employees and management. Organizational leaders honor psychological contracts to take advantage of the talented employees that can benefit the organization. Psychological contracts assist leaders guiding their organization through changes by creating intrinsic motivators to develop an understanding of expectations. Changes that need to occur should be well communicated and implemented at a time that offers the organization and advantage rather than a setback. Leadership differs from management by requiring an alternative approach when dealing with employees and how to direct change at the individual, group, or larger system level. Organizational leaders create an environment for change that must be nurtured for the employees to commit to following the leader. Organizational change develops throughout the life cycle of an organization and is dependent on the organizational leader’s willingness to continue to learn.
On Legal Interpretation of Basic Consumer Rights
Authors: Mróz Teresa
Published: May 2018

The liability of an entrepreneur towards a consumer is the specific kind of contractual responsibility. The typical feature of this regime is weakness of two principles that are basic for market economy: freedom of contracts and pacta sunt servanda principle. This liability is regulated by specific acts of law. Its object is to intensify the legal protection of the consumer.

Nowadays in the Polish law, the form of legal provisions concerning pro- tection of the consumer, is influenced by European Union law, especially con- sumerist directives. The Act on specific terms and conditions of consumer sale, on 27th July 2002, has huge practical significance. The basic premise of this lia- bility is the fact of ’nonconformity of goods with the contract’. Therefore there is no need to prove any damage and other premises inseparably connected with damage liability. Moreover, it must be noticed that normally specific acts of law concerning protection of the consumer, do not entirely realize the compensatory function which is typical of general principles of contractual responsibility.
Limits of the Prohibition of Using Personal Data of Social Assistance Beneficiaries
Authors: Miruć Alina
Published: May 2018

The objective of this paper is to present the limits of using personal data of the social assistance beneficiaries. Therefore, it will analyse issues concerning such terms as personal data, the essence of its protection, the essence of the limit in personal data use, acceptability and rules of personal data pro- cessing on the grounds of both general and specific legal solutions included in the Act on Social Assistance.

It is important to emphasise that the limits of using personal data of the persons benefitting from social security are determined by means of legal solutions referring to personal data protection. The basic regulation in this question is APDP of 29 August 1997, and specific solutions may be found foremost in Article 100 ASA of 12 March 2004, which implies that in the proceedings on social assistance benefits it is important to pursue primarily the good of social assistance beneficiaries, as well as protection of their personal rights. In particular, the names of social assistance beneficiaries and the type and range of the benefit granted must not be published. On the other hand, to a degree necessary for granting and allotting social assistance benefits, it is allowed to process personal data of applicants for and users of these benefits referring to: ethnic origins, state of health, bad habits, convictions, statements of penalties, as well as other statements issued in judicial or administrative proceedings. The existence of exceptions which allow making beneficiaries’ personal data avail- able is justified. Every acceptance of revealing social assistance beneficiaries’ personal data is subject to many provisions of universally binding law, due to which beneficiaries may protect their rights and good name.

Authors: Rudolf Boris
Published: May 2018

The boundary value problem for a differential equation with one dimensional p-Laplacian is studied. The technique of lower and upper solutions is used. The existence of a solution for well ordered and unordered case as well as the existence of multiple solutions are proved. The growth condition is assumed only on a part of the nonlinearity.
On Some Difference Equations of First Order
Authors: Vasilyev Vladimir B.
Published: May 2018

One considers two boundary value problems for the Laplacian and biharmonic operator in a plane sector with boundary conditions of the Dirichlet and the Neumann type on the angle sides. The system of difference equations of first order to which this problem is reduced, is explicitly written out. Certain cases of solvability for such difference equations of first order are described; it will be useful for studying similar equations.

New trends in social housing allocation – case study (City of Poznań, Poland)
Authors: Suszyńska Katarzyna , Rataj Zuzanna
Published: May 2018

In recent years, the allocation of social housing has undergone a radical change. Local governments as well as housing organisations providing social housing are revising the procedures applied in the field by modifying methods for ranking applications. European experience shows that the general tendency is to replace the traditional allocation mechanism based solely on the criteria of income and needs with the one incorporating (though to a limited extent) the preferences of potential tenants. An example of innovative practice is announcing unoccupied social flats in the press and on the Internet which gives prospective tenants the opportunity to rethink the match between the housing conditions offered and the household’s needs. The aim of the paper is to explore various models of housing allocation used by local governments in EU countries and identify new trends within the field. A special focus is on the local regulations applied in the City of Poznań. Some information applied in the process of preparation of the paper has been obtained while conducting the research project “Social housing and its role in satisfying the housing needs of indigent households in Poland” financed by the National Science Centre (2014/13/N/HS4/02100).
Urban design for mobilities – towards material pragmatism
Authors: Jensen Ole B.
Published: May 2018

The aim of this paper is twofold: firstly, to present a critique of mainstream transport thinking based on the so-called ‘mobilities turn’, and secondly to connect this to a design perspective. The aim is thus to establish this reflection based upon a theoretically informed discussion. In this paper, we shall explore the potential for a better understanding of contemporary urban challenges through the cross-disciplinary approach of ‘mobilities design’. The paper investigates how this notion is based on an understanding of materialities and social action that is framed under the heading of ‘material pragmatism’. The paper critically discusses transport versus mobilities and uses the combination of urban design and mobilities not just to argue for a pragmatic approach to urban transformation, but also to illustrate how such a different frame of understanding is better suitable for the ‘kind of a problem a city is’ to paraphrase the well-known urban scholar Jane Jacobs.
Preliminary results of sulphur isotope studies on sulfides from selected ore deposits and occurrences in the Karkonosze–Izera Massif (the Sudety Mts., Poland)

Published: May 2018

Preliminary sulphur isotope data are presented for selected ore deposits and occurrences in the Karkonosze-Izera Massif, namely, polymetallic mineralization sites at Budniki, Ciechanowice, Izerskie Garby and Sowia Dolina, and the pyrite deposit at Wieściszowice. The data reveal two populations of δ34S values: from 2.74 to 3.95‰ (pyrrhotites and pyrites in Sowia Dolina, and some pyrites in Wieściszowice) and from 0.79 to 1.8‰ (pyrites in Budniki, Ciechanowice and Izerskie Garby, and some pyrites from Wieściszowice). All of the data are indicative of endogenic sulphur typical of hydrothermal mineralization despite the genetic differences between the sites.
Reinforcement learning in discrete and continuous domains applied to ship trajectory generation
Authors: Rak Andrzej , Gierusz Witold
Published: May 2018

This paper presents the application of the reinforcement learning algorithms
to the task of autonomous determination of the ship trajectory during the
in-harbour and harbour approaching manoeuvres. Authors used Markov
decision processes formalism to build up the background of algorithm
presentation. Two versions of RL algorithms were tested in the simulations:
discrete (Q-learning) and continuous form (Least-Squares Policy Iteration).
The results show that in both cases ship trajectory can be found. However
discrete Q-learning algorithm suffered from many limitations (mainly curse
of dimensionality) and practically is not applicable to the examined task. On the other hand, LSPI gave
promising results. To be fully operational, proposed solution should be extended by taking into account
ship heading and velocity and coupling with advanced multi-variable controller.
Dynamic positioning system design for “blue lady”. simulation tests
Authors: Tomera Mirosław
Published: May 2018

The dynamical positioning system is a complex control consisting of a number of
components, including: filters, observers, controllers, and propeller allocation systems.
The design and preliminary analysis of operational quality of system operation are usually
done based on numerical simulations performed with the aid of the mathematical model
of the ship. The article presents a concept of the dynamic positioning system applied to
steering the training ship Blue Lady used for training captains in the ship handling research
and training centre owned by the Foundation for Safety of Navigation and Environment
Protection in Ilawa/Kamionka. The simulation tests performed in the numerical environment
of Matlab/Simulink have proved the usability of the designed system for steering a ship at low speed.
Measuring system for parallel moving ships
Authors: Waszkiel Anna
Published: May 2018

The paper introduces algorithm for determining the relative positions of two ships
manoeuvring as a pair. This algorithm also takes into account determination of angle γ,
which is difference between present approaching vessel and guidance vessel course. Relative
positioning system is a vision system based on three colours LEDs matrix and rotating
CCD camera. There are presented ways of distance calculation based on photogrammetric
methods from the known distance between the characteristic points of the real. Several
possible cases are taken into account. The considerations have been illustrated on the
basis of model of the system. These results confirm the correctness of the operation of the algorithm that
is used by the designed measuring system.
A new method for a preliminary definition of a high–performance rudder for tuna purse seiners
Authors: Martínez–López Alba , Munín–Doce Alicia
Published: May 2018

The aim of this paper is to provide a simple method for the definition of a rudder for tuna purse seiners.
The model achieved by the application of this method ensures the manoeuvrability of initial turning,
course keeping and yaw checking. For this, the results obtained by other authors, through rudder tests and
manoeuvrability tests of fishing vessels have been integrated with the recommendations of the International
Normative. Finally, in the paper the method is applied to the case of a tuna vessel, providing a rudder model
which could be optimised with CFD (Computer Fluid Dynamics) in further tests. The method proposed
can be applied to other vessels whose main dimensions are met.
Effect of the working liquid compressibility on the picture of volumetric and mechanical losses in a high pressure displacement pump used in a hydrostatic drive part ii mechanical losses in a pump
Authors: Paszota Zygmunt
Published: May 2018

Working liquid compressibility may considerably change the values and proportions of
coefficients of the volumetric and mechanical energy losses in the displacement pump used
in a hydrostatic drive system. This effect can be particularly seen in the operation under
high pressure and also in the system, where aeration of the working liquid can occur. In
the Part II the mathematical model is presented of the torque of mechanical losses in the
pump and its laboratory verification. Conclusions are drawn regarding the effect of working
liquid compressibility on the mechanical and volumetric losses in the pump.
