Competition and the Efficiency of Markets for Technology
Authors: Allain Marie-Laure , Henry Emeric , Kyle Margaret
Published: October 2015

The sale of ideas through licensing facilitates the division of labor between the separate activities of research and development. This vertical specialization can improve the overall efficiency of the innovative process. However, these gains depend on the timing of the sale: the buyer of an innovative project should assume development at the stage at which he has an efficiency advantage. Using data from the pharmaceutical industry, we show that competition between potential buyers is related to the timing of licensing. Furthermore, the effect differs by the type of competitor. We then describe a class of models that yields predictions consistent with these empirical patterns. Our key insight is that increased competition may increase licensing delays and hence inefficiency.

Pregnancy-induced hypertension and associated factors among pregnant women attending public health facilities in Swaziland
Authors: Mbonane Siphesihle , Ziyane Isabella
Published: October 2015

Background/Aims:

Pregnancy-induced hypertension is the main cause of morbidity and mortality among pregnant women in Swaziland. The main objectives of this study were to: i) identify the factors contributing to the development of pregnancy-induced hypertension among women attending public health facilities in Swaziland; ii) investigate the association between the development of pregnancy-induced hypertension sociodemographic variables, family history, obstetric history, lifestyle, and access to health care services.

Methods:

An exploratory, descriptive research design, using a quantitative research approach was used. Data were analysed using SPSS version 20, where a sample frame of 60 women diagnosed with pregnancy-induced hypertension, and a sample of 50 women was selected using simple random sampling.

Results:

The findings revealed a significant association between sociodemographic variables and obstetric history (p=0.001), marital status (p=0.025) and lifestyle, which in turn predisposes the woman to pregnancy-induced hypertension. Employment status (p=0.044) was significantly associated with access to health care services and level of education (p=0.027).

Conclusions:

Factors that are significantly associated with the development of pregnancy-induced hypertension include age, multiple pregnancy, a history of pregnancy-induced hypertension in previous pregnancies and limited use of antenatal care services. The authors recommend strengthening pre- and in-service midwifery education on the management of pregnancy-induced hypertension, as well as client education on the risk factors for pregnancy-induced hypertension.

Published: October 2015

Background/Aims:

Bra cup size is associated with pectoral girdle myalgia in women. this study investigated the prevalence of pectoral girdle myalgia in a population of nigerian women and the association of pectoral girdle myalgia with the congruence of measured vs reported bra size.

Methods:

291 females aged 15–50 years completed a 31-item biodata questionnaire, which included questions on attributed pain to bra use. A chi-squared test was used to determine the association between age, cup size, congruence of measured vs reported bra size, and occurrence of pectoral girdle myalgia.

Results:

The 12-month prevalence of pectoral girdle myalgia was 44% (n=122). There was no association between age, cup size, congruence of measured vs reported bra size, and occurrence of pectoral girdle myalgia (p>0.05).

Conclusions:

Pectoral girdle myalgia was found to be common among the respondents. The fact that the size of bra worn was largely dependent on self-selection might have been responsible for the high number of respondents wearing wrong-sized bras. Working with the arms elevated had a significant association with the development of pectoral girdle myalgia (χ2=4.12, p=0.040), a finding that requires further exploration.

A dialogue of one: Reflection on visual practice through drawing
Authors: Croft Michael
Published: October 2015

This article concerns the reflection of the author on his visual practice. The author carried out a piece of work in the medium of drawing-based painting for this purpose. The work is on canvas and was situated in the right angle of two adjoining walls of a studio. The process was recorded visually using stop-motion photography, reference to stills of which are included at the end of the article. The author also spoke his thoughts into a voice recorder while drawing, the transcripts providing, as nearly as possible, subjective reflexive content for the author’s more analytical reflection. Summaries of the transcripts are included in the article as well as some excerpts included as long-form captions alongside photographic images. The article involves questions of the author’s own corporeal embodiment in the drawing, self-performance as a mode of content, and the author’s individual working process as the work’s narrative. Theoretical references are to phenomenology, philosophy of perception and some recent articles concerning research from a practice basis.
See for yourself: Drawing (out) the interiors of vision1
Authors: Imperatore Lynn
Published: October 2015

Drawing can apprehend and articulate from unexpected edges of the visual field/perceptual world – even as the draughtsman seeks to record ostensibly straightforward observation. Drawing is a sleight-of-hand that registers and interprets through layers of vision – by shifting regard between what is perceived and what is imagined, between the percept and the image. In ordinary perception, the disposition of sight is oriented towards expectation, in a visual regime that reinforces what meets the eye (rather than the ‘I’). Yet the view towards drawing allows for reception of other data: perception that un-enforces to expand or distil apprehension, to allow us to see more, or less, than what meets the eye. Even the established techniques that inform the western traditions of drawing – as an acquired expressive skill – coalesce around specified rules that direct us to alter the pose and project of vision; isolating our look to contour, value, negative spaces and so on. From such discrete and reconfigured repositions in seeing, ‘honest’ representations of observation may become recognized and recorded. But what constitutes a measurement of such honesty of sight? Too often, the strategies of looking for drawing are applied to merely achieve mimicry of expectations of perception. If limited thus, we neglect to ‘see’ how drawing can open onto intervals at the peripheries of vision, onto dormant agents of perception: the subtleties of reflection, the borders of sleep and dreams, the auras and occlusions that flicker across our gaze and our imagination everyday. An observant artist cultivates the ability to withhold aspects of cognition and recognition from perception and – through drawing – purposely and purposefully cultivates a capacity to withhold conclusion based upon preconception. By tracking and recording glimpses into the ephemeral, drawing discloses a fuller account of embodied life.
Designing an artificial environment to create contemporary experimental drawings: An analytical and experimental study
Authors: Ahmedien Diaa Ahmed Mohamed
Published: October 2015

This article describes a non-traditional attempt to build a miniature artificial environment that seeks and creates experimental drawings. With microscopic techniques, ink gel was injected into tiny blocks of solid ice in a custom-made chamber. This process allowed us to create some artistic sketches on the inner surface of ice blocks. With our innovative technique we were able to control the ink distribution rate inside the ice blocks, and then we have already recorded ink paths as artistic sketches with microscopic recording processes. The experiment aimed to answer three questions: can we reinterpret the contemporary art of drawing through some contemporary concepts that deal with the art of drawing as an interactive process? How can we examine the effects of the technological aspects and scientific procedures on the interactive processes in contemporary experimental drawings? To what extent can this experiment contribute to redefine a key standard in twentyfirst century aesthetics? This case study hopes to enhance our understanding of the conceptual content of some contemporary experimental drawings, not only technically, but also by linking our results to leading artworks that have already had considerable impact on a wide range of artistic trends.
Juristische und theologische Dogmatik
Authors: Welker Michael
Published: October 2015

This article refers to the recent German discussion on the role and function of legal dogmatics. The insistence among legal scholars on relating the evolution of the law to academic work, to the praxis of the courts and on locating it in truth-seeking communities, but also the insight into the multifunctionality of dogmatics open up ways for a comparison of legal and theological dogmatics. The article identifies nine levels in legal and theological dogmatic thought and orientation which lead to fruitful observations of commonalities and differences of legal and theological normativity.
Das »Große Welthaus«
Authors: Haspel Michael
Published: October 2015

In this article Martin Luther King, Jr.’s concept of active non-violent resistance and his stand against the Vietnam War are reconstructed in their historical and societal context, following his own theological concept of contextualization. The findings suggest that King combines fundamental and contextual arguments to sustain his position. It is argued that in order to apply his positions to the current questions of peace and war, King’s arguments have to be recontextualized. Special emphasis is laid on King’s theological concept of human dignity and human rights as well as his vision of a Great World House as unique contributions to the peace discourse of his time and beyond.
Terrorismus und politische Theologie
Authors: Moltmann Jürgen
Published: October 2015

Bakunin’s anarchism on the one hand and Carl Schmitt’s State-God on the other mirror each other. Either concept is about the non-accountable, »absolute« political decision. Both modern terrorism and the political reaction to it in the »security state« follow the alternative Bakunin-Schmitt. By contrast, the »open society« of democracy needs the Christian, intelligent love of enemies to deal with its enemies without self-destruction.
Three-fold Thinking on the Sinicization of Christianity
Authors: Zhigang Zhang
Published: October 2015

This essay investigates the concept of »Sinicization of Christianity« from an »academic« standpoint, the goal being to discuss more objectively and rationally how Christianity may be able to meld into Chinese culture, the Chinese nation, and in particular, contemporary Chinese society. The investigation is presented in three parts: a comparison between the histories of Christianity in China and Korea, a study of the ecological situation of religions in contemporary China, and new developments in international research on interreligious dialogue. The article concludes that social practice should be the main criterion for testing religious faith, and that, based on China’s current conditions, the best course for the Sinicization of Christianity is to make positive and important contributions to continued reform and opening-up of Chinese society and to its development and progress.
A New Model Village? Nairobi Development and the Somali Question in Kenya, c. 1915–17
Authors: Whittaker Hannah
Published: October 2015

Kenya has a problem with its urban ethnic Somali population. Those who reside in suburbs of Nairobi are assumed to have entered the country illegally from Somalia, or to have migrated from the large refugee camps located in Dadaab and Kakuma in the north of the country. As such many perceive the Somali to be temporarily encamped in the city. This is despite the fact that Somali claims in Nairobi can be traced back to the first establishment of the British East Africa Protectorate. By outlining the history of a proposed new model village for the Somali, and the ways in which urban Somalis negotiated early British development of the city, this article emphasizes the longevity of Somali claims for rights and recognition from the state. Even though the British perceived them as nomads and livestock traders, and therefore not part of the city’s future, they actively negotiated their resettlement. The article argues that this was not simply and expression of political demands, but also a manifestation of an urban aspiration that is also reflected in more recent Somali migration to urban areas.
Mamluk Historiography Outside of Egypt and Syria: ʿAlī b. ʿAbd Allāh al-Samhūdī and his Histories of Medina
Authors: Munt Harry
Published: October 2015

This article is an investigation into the extant works on Medina’s history by the late Mamluk-era historian ʿAlī b. ʿAbd Allāh al-Samhūdī (d. 911/1506), the most prolific pre-modern historian of that town. Although the study of Arabic historiography during the Mamluk period has progressed rapidly over recent years, most published research focuses on historical works composed in Egypt and Syria. By offering an analysis of al-Samhūdī’s various books on Medina’s history, this article will demonstrate how the study of historical works written in the Mamluk Ḥijāz has much to add to wider research into Mamluk historiography more broadly.
Hierarchical Supervisor and Agent Routing Algorithm in LEO/MEO Double-layered Optical Satellite Network
Authors: Li Yongjun , Zhao Shanghong
Published: October 2015

A novel routing algorithm (Hierarchical Supervisor and Agent Routing Algorithm, HSARA) for LEO/MEO (low earth orbit/medium earth orbit) double-layered optical satellite network is brought forward. The so-called supervisor (MEO satellite) is designed for failure recovery and network management. LEO satellites are grouped according to the virtual managed field of MEO which is different from coverage area of MEO satellite in RF satellite network. In each LEO group, one LEO satellite which has maximal persistent link with its supervisor is called the agent. A LEO group is updated when this optical inter-orbit links between agent LEO satellite and the corresponding MEO satellite supervisor cuts off. In this way, computations of topology changes and LEO group updating can be decreased. Expense of routing is integration of delay and wavelength utilization. HSARA algorithm simulations are implemented and the results are as follows: average network delay of HSARA can reduce 21 ms and 31.2 ms compared with traditional multilayered satellite routing and single-layer LEO satellite respectively; LEO/MEO double-layered optical satellite network can cover polar region which cannot be covered by single-layered LEO satellite and throughput is 1% more than that of single-layered LEO satellite averagely. Therefore, exact global coverage can be achieved with this double-layered optical satellite network.
Some remarks on lexicographic treatment of idioms
Authors: Włodarczyk-Stachurska Anna
Published: October 2015

Phraseology is a domain of linguistic study which, to a certain extent, demonstrates the correlation between language and culture. At the same time, it is a source of information concerning the speakers’ world view. However, different phraseological units are used in different languages. Hence, when it comes to their understanding, it becomes particularly difficult to comprehend their meaning without the reference to their lexicographic description. The aim of this paper is to outline the treatment of selected idioms in several dictionaries in order to:

(i) identify how idioms are lexicographically presented,

(ii) find equivalence of some expressions of that kind in English/Polish,

(iii) investigate how the recorded parallels correspond with the functional view of idioms proposed by Dobrovol’skij (2000).
Cultural Influences in a multicultural academic workplace
Authors: Winch Junko
Published: October 2015

This study investigates if there are any cultural influences on language teaching staff in a multicultural British university language centre operating overseas. Language teaching staff who work at British universities in the UK usually involve only two cultures (British and their mother tongue culture). If non-native nationals are involved in two cultures, it is expected that they would conform to the host country’s culture. Language teaching staff in this study involve at least three cultures, that is, British, their mother tongue culture and the host country’s culture. In the case of the involvement of the three cultures, where do the majority of non-native nationals conform to in a multicultural workplace in the host country? Is it the institution’s country’s culture where they are based in their educational operation or the host country’s culture? This study looks at individual value orientation in decision-making and problem-solving. Discourse analysis of e-mails between 20/10/2013 and 20/01/2014 was used to focus on two main language staff (French and Japanese). The results showed that teaching staff in the multicultural workplace seemed to alter and replace their own value orientations on a mix and match basis, which may affect their preferred culture. It is also suggested that cultural acquisition could occur regardless of the establishment of one’s cultural preference.
The thousand and one tries: Storytelling as an art of failure in Rabih Alameddine’s Fiction
Authors: Tabačková Zuzana
Published: October 2015

The paper discusses experimental fiction of Rabih Alameddine, an American writer of Lebanese origin, whose literary pursuits subvert Orientalist discourse based on the East/West dichotomy by focusing on the commonalities of the two. The recurring motif of searching for one’s identity (while being trapped in-between two mutually distant and at the same time similar worlds) is reflected in the subversion of the traditional understanding of the narrative which is destined to a constant failure. Alameddine’s storytelling is, in reality, a “story-trying.“ By employing multiple narrators, intertwining plots, genres and languages, the author is striving hard to tell “hisstory” about American homophobia, Lebanese sectarianism as well as the physical and psychological outcomes of war - a story which turns up to be a narration of the thousand and one failed beginnings.
Suffering wives: Miller’s Linda and Mahfouz’s Amina
Authors: Abouelmaaty Atef Abdallah
Published: October 2015

The theme of suffering female characters has been the interest of both the drama and the novel of the late nineteenth and early twentieth centuries. Among those who are interested in the matter are the Noble Prize winners Arthur Miller and Naguib Mahfouz in Death of a Salesman (1949) and Palace Walk (1956). Both of Miller’s Linda and Mahfouz’s Amina have greatly suffered at the hands of their tyrannical husbands Willy Loman and Al- Sayyid Ahmad Abd-Elguaad respectively. The main aim of this paper is to study the sources, forms, and consequences of the sufferings of both Miller’s Linda and Mahfouz’s Amina, and to place their sufferings against the current beliefs of the age in which they lived. The reason behind choosing these two characters is that they look like each other in many ways. First, they are reliable, trusted wives and mothers who are dedicated to the welfare of their families. Second, they face the same inherently patriarchal cultures and suffer the same misogyny. Third, they are different from other tragic wives like Shakespeare's Desdemona, who are created to meet Aristotle's tragic requirements.
Queering gender in contemporary female Bildung narrative
Authors: Šnircová Soňa
Published: October 2015

The paper explores, in the context of feminist discussions about the Bildungsroman, a contemporary British novel that offers shocking images of female coming of age at the turn of the millennium. Queering gender and introducing male elements into the heroine’s process of maturation, the analysed novel appears to raise questions about the continuous relevance of the feminist distinction between male and female version of the genre. The paper however argues that although significantly rewriting both female Bildung and pornographic narratives, Helen Walsh’s Brass can still be read as a variation of the female Bildungsroman and an example of its contemporary developments.
On the Modal μ-Calculus Over Finite Symmetric Graphs
Authors: D’Agostino Giovanna , Lenzi Giacomo
Published: October 2015

In this paper we consider the alternation hierarchy of the modal μ-calculus over finite symmetric graphs and show that in this class the hierarchy is infinite. The μ-calculus over the symmetric class does not enjoy the finite model property, hence this result is not a trivial consequence of the strictness of the hierarchy over symmetric graphs. We also find a lower bound and an upper bound for the satisfiability problem of the μ-calculus over finite symmetric graphs.
Some Notes on Elimination Properties for The Theory of Riesz MV-Chains
Authors: Marchioni Enrico
Published: October 2015

Riesz MV-algebras are a variety of algebras strongly connected to Riesz spaces. In this short article we investigate some elimination properties of the first-order theory RMV of linearly ordered Riesz MV-algebras and show that RMV admits elimination of quantifiers and uniform elimination of imaginary elements. In the process, we also prove several other results such as modelcompleteness, o-minimality, definability of Skolem functions, and a version of the Di Nola Representation Theorem for Riesz MV-algebras.
Possibilistic and Probabilistic Logic under Coherence: Default Reasoning and System P
Authors: Coletti Giulianella , Scozzafava Romano , Vantaggi Barbara
Published: October 2015

Some results on coherence in probabilistic and in possibilistic frameworks are presented in order to deal with nonmonotonic reasoning. Moreover, we extend these results to conditional decomposable measures. We deal with entailment and prove that it satisfies the axiomatization of System P by referring to conditional necessities or to specific conditional decomposable measures (which include conditional probability). Finally, we study some aspects concerning a notion of irrelevance.
Functional Many-Valued Relations
Authors: Della Stella M. E. , Guido C.
Published: October 2015

Many-valued binary relations are considered, taking values in a complete lattice, possibly equipped with additional operations that characterize extended-order algebras. The functionality of such relations is defined, by means of properties such as univocality and totality, from three different perspectives, namely from the viewpoint of α-cuts, of composition and of powerset operators, respectively.

Functional many-valued relations are generalizations of functions and special care is devoted to characterize those which are actually functions. Relationships between the involved concepts are discussed with several results and examples.

Authors: Askerzade I.N. , Tagiyeva Askerbeyli R. T.
Published: October 2015

In this study we have calculated the fluctuation conductivity near critical temperature of SmFeAsO0.8F0.2 superconductor using two-band Ginzburg-Landau theory. It was illustrated that in the absence of external magnetic field, the two-band model reduced to a single effective band theory with modified temperature dependences. The calculations revealed three-dimensional character of fluctuations of conductivity in the new Fe-based superconductor SmFeAsO0.8F0.2. It has been shown that such a model is in good agreement with experimental data for this compound.

Authors: Dychalska Anna , Fabisiak Kazimierz , Paprocki Kazimierz , Dudkowiak Alina , Szybowicz Mirosław
Published: October 2015

Evolution of residual stress and its components with increasing temperature in chemical vapor deposited (CVD) diamond films has a crucial impact on their high temperature applications. In this work we investigated temperature dependence of stress in CVD diamond film deposited on Si(100) substrate in the temperature range of 30 °C to 480 °C by Raman mapping measurement. Raman shift of the characteristic diamond band peaked at 1332 cm-1 was studied to evaluate the residual stress distribution at the diamond surface. A new approach was applied to calculate thermal stress evolution with increasing tempera­ture by using two commonly known equations. Comparison of the residts obtained from the two methods was presented. The intrinsic stress component was calculated from the difference between average values of residual and thermal stress and then its temperature dependence was discussed.
Applications of magnetic nanoparticles in biomedical separation and purification
Authors: Yildiz Ibrahim
Published: October 2015

In recent years, nanoparticle formulations utilizing magnetic materials have started gaining more consideration in the biomedical arena due to their inherent superparamagnetic/paramagnetic nature paving ways to develop assays and sensors benefitting mostly magnetic separation technique. Coupled with the developments in the synthetic field in obtaining controlled-sized particles and surface functionalities, a variety of sensitive and selective assays have been developed ranging from detection/separation/enrichment of antibodies, enzymes, proteins, and nucleic acids to whole cells, virus, and pathogens utilizing a variety of signal transduction mechanisms including fluorescence, surface plasmon resonance, and magnetic resonance. In addition to ongoing research in this field, there are already commercialized products engineered to detect and quantify biomolecules with proper surface formulations. Owing to the immensity of applications of magnetic particles, in this article, recent trends in the design and applications of iron oxide nanoparticles will be reviewed.
Popular Religion in the Periphery. Church Attendance in 17th Century Eastern Finland
Authors: Kuha Miia
Published: October 2015

On the fringes of post-Reformation Europe, church and state authorities faced problems in enforcing church attendance. In the Swedish kingdom, religious uniformity was seen as vital for the success of the state after the Lutheran confession had been established, and absences from church were punishable by law. The seventeenth century saw significant tightening of legislation relating to church absences and other breaches of the Sabbath, and severe punishments were introduced. Despite considerable deterrents, it was sometimes difficult to control local inhabitants: absence cases were regularly brought before the local courts in Eastern Finland, where authorities were hampered by a combination of geographical distance and a highly mobile population. In this article, popular church-going practices are studied with an approach inspired by historical anthropology. In popular practice church attendance was required only on the most important holy days of the year, whereas on Sundays and prayer days, work or leisure were considered socially acceptable pursuits. Explanations of nonattendance should not only make reference to trying conditions: in certain situations people would travel long distances to church, despite the obvious difficulties they faced. Popular religious traditions and old conceptions of sacred time also affected behaviour among peasants. The great holy days of the year formed a ritual cycle, the aim of which was the maintenance of good relations with the supernatural. For the success of oneself and one’s household, it was more important to follow the norms of popular culture than the orders of the authorities.
Limits of Power. Clerical Appointment as Part of Domestic Policy in Sweden after the Reformation, 1560–1611
Authors: Hiljanen Mikko
Published: October 2015

This article examines state-church relations in Sweden by analysing clerical appointment processes in the latter part of the 16th century. The aim is to ascertain whether the king of Sweden could appoint pastors independently, and if not, with whom he was compelled to share the power. Earlier studies argue that the power of the king grew due to the reformation. First, this article examines the number of clerical appointments that were made in the period 1560-1611. The results reveal a remarkable annual variation in the number of clerical appointments. Second, the timing and share of clerical appointments made by the king are studied. The number of appointments made by the king is viewed against the total number of clerical appointments so as to reveal the importance of appointments made by the crown. Third, the article examines the proportion of appointments made by other authorities. The results suggest that the crown’s role in clerical appointment processes varied, but more interestingly, it was not as ubiquitous as earlier researchers suggest. Thus article concludes that crown’s power over the church in 16th century Sweden was not as vast as it has previously been claimed.
Numerical Analysis of Consolidation Settlement and Creep Deformation of Artificial Island Revetment Structure in a Large-Scale Marine Reclamation Land Project

Published: October 2015

In order to analyze the influential factors of soft foundation settlement in a marine reclamation land project, the consolidation settlement and pore pressure dissipation of the entire area are numerically simulated using Soft-Soil- Creep Model, in which the PLAXIS finite element software for professional geotechnical engineering is applied and empirical data of Japanese Kansai’s airport project are used. Moreover, the figures of settlement and pore pressure results in the different basic period are drawn, and the corresponding analysis conclusions are ob-tained based on the comparison among the results from the computational parameters of depth. In addition,, the influence rules of various parameters on settlement results is concluded through running the parameter sensitivity analysis in Soft-Soil-Creep Model, and the experience and conclusions can be for reference in the design and con-struction of similar large-scale marine reclamation land project. Also the empirical value method of the creep index has not been applied widely. Further research needs to be done.
Dynamic Strength and Accumulated Plastic Strain Development Laws and Models of the Remolded Red Clay under Long-Term Cyclic Loads: Laboratory Test Results
Authors: Li Jian , Chen Shanxiong , Jiang Lingfa
Published: October 2015

The dynamic strength and accumulated plastic strain are two important parameters for evaluating the dynamic response of soil. As a special clay, the remolded red clay is often used as the high speed railway subgrade filling, but studies on its dynamic characteristics are few. For a thorough analysis of the suitability of the remolded red clay as the subgrade filling, a series of long-term cyclic load triaxial test under different load histories are carried out. Considering the influence of compactness, confining pressure, consolidation ratio, vibration frequency and dynamic load to the remolded red clay dynamic property, the tests obtain the development curves of the dynamic strength and accumulated plastic strain under different test conditions. Then, through curve fitting method, two different hyperbolic models respectively for the dynamic strength and accumulated plastic strain are built, which can match the test datum well. By applying the dynamic strength model, the critical dynamic strength of the remolded red clay are gained. Meanwhile, for providing basic datum and reference for relevant projects, all key parameters for the dynamic strength and accumulated plastic strain of the remolded red clay are given in the paper.
Establishment of Motion Model for Wave Capture Buoy and Research on Hydrodynamic Performance of Floating-Type Wave Energy Converter
Authors: Gao Hongtao , Li Biao
Published: October 2015

Floating-type wave energy converter has the advantages of high wave energy conversion efficiency, strong shock resistance ability in rough sea and stable output power. So it is regarded as a promising energy utilization facility. The research on hydrodynamic performance of wave capture buoys is the precondition and key to the wave energy device design and optimization. A simplified motion model of the buoys in the waves is established. Based on linear wave theory, the equations of motion of buoys are derived according to Newton’s second law. The factors of wave and buoys structural parameters on wave energy absorption efficiency are discussed in the China’s Bohai Sea with short wave period and small wave height. The results show that the main factor which affects the dynamic responses of wave capture buoys is the proximity of the natural frequency of buoys to the wave period. And the incoming wave power takes a backseat role to it at constant wave height. The buoys structural parameters such as length, radius and immersed depth, influence the wave energy absorption efficiency, which play significant factors in device design. The effectiveness of this model is validated by the sea tests with small-sized wave energy devices. The establishment methods of motion model and analysis results are expected to be helpful for designing and manufacturing of floating-type wave energy converter.

Numerical Investigation of the Undrained Compression and Pull-Out Capacity of Suction Foundations in Clay
Authors: Du Jiaqing , Du Shouji , Shen Shuilong , Yin Zhenyu
Published: October 2015

This paper presents the results of three-dimensional finite difference analysis of suction foundations in uniform and non-uniform clays under undrained conditions. The Tresca criterion was used to simulate the stress-strain response. The bearing capacity of the foundations was investigated, with the degree of nonhomogeneity (kD/sum) of soil varying from 0 to 5, and the embedment depth being up to four times the foundation diameter. The end bearing capacity factor in compression and the reverse bearing capacity factor in tension were both calculated and were compared with each other under different foundation displacements. Numerical results showed that the ultimate bearing capacity factor can have the same value in cases of both compression and tension. The recommended ultimate bearing capacity factor is determined on the basis of the embedment ratio and displacement magnitude, and the displacement is not more than 30% of the foundation diameter. Finally, two equations are proposed to evaluate both the bearing capacity factor and the effective depth factor.

Learning from the motion principle of quadrotor, a symmetric propeller AUV, which has small size and low velocity is designed. Compared with the AUV equipped with rudders, it has better maneuverability and manipulation at low velocity. According to the Newton-Euler method, the 6 DOF kinematic model and dynamic model of the propeller AUV are established. A stability controller that consists of 3 different PID controllers is designed. It makes the depth and attitude angle as trigger conditions, and the relevant controller is chosen in different moving process. The simulation experiments simulate ideal motion state and disturbed motion state, and experiments results show that the stability controller based on combined sections method can make the best of mature technology of PID, and meet the control requirements in different stages. It has a higher respond speed and accuracy, improving the stability of the propeller AUV under the disturbance of complex ocean currents.

Published: October 2015

In this study numerical and analytical approaches were investigated in terms of accuracy of their results, practicality of solution and ability to reproduce the main features of the parametric roll phenomenon such as loss of stability and bifurcations in parametric roll motion analysis of ships. In general, single-degree-of-freedom analytical approach is based on reducing number of degrees of freedom from 3 to 1 by using the quasi-static Froude-Krylov assumption, incorporating heave and pitch effects by means of a time varying restoring moment. On the other hand, numerical approaches to motion of six and four degrees of freedom are based on three dimensional diffraction/radiation and potential flow theories. In summary, this paper reveals that analytical approaches are sufficiently adequate to obtain accurate practical results for this relatively complex phenomenon.

The SatBałtyk (Satellite Monitoring of the Baltic Sea Environment) project is being realized in Poland by the SatBałtyk Scientific Consortium, specifically appointed for this purpose, which associates four scientific institutions: the Institute of Oceanology PAN in Sopot - coordinator of the project, the University of Gdańsk (Institute of Oceanography), the Pomeranian Academy in Słupsk (Institute of Physics) and the University of Szczecin (Institute of Marine Sciences). The project is aiming to prepare a technical infrastructure and set in motion operational procedures for the satellite monitoring of the Baltic Sea ecosystem. The main sources of input data for this system will be the results of systematic observations by metrological and environmental satellites such as TIROS N/NOAA, MSG (currently Meteosat 10), EOS/AQUA and Sentinel -1, 2, 3 (in the future). The system will deliver on a routine basis the variety of structural and functional properties of this sea, based on data provided by relevant satellites and supported by hydro-biological models. Among them: the solar radiation influx to the sea’s waters in various spectral intervals, energy balances of the short- and long-wave radiation at the Baltic Sea surface and in the upper layers of the atmosphere over the Baltic, sea surface temperature distribution, dynamic states of the water surface, concentrations of chlorophyll a and other phytoplankton pigments in the Baltic waters, spatial distributions of algal blooms, the occurrence of coastal upwelling events, and the characteristics of primary production of organic matter and photosynthetically released oxygen in the water and many others. The structure of the system and preliminary results will be presented.

Published: October 2015

The recently deployed supercomputer Tryton, located in the Academic Computer Center of Gdansk University of Technology, provides great means for massive parallel processing. Moreover, the status of the Center as one of the main network nodes in the PIONIER network enables the fast and reliable transfer of data produced by miscellaneous devices scattered in the area of the whole country. The typical examples of such data are streams containing radio-telescope and satellite observations. Their analysis, especially with real-time constraints, can be challenging and requires the usage of dedicated software components. We propose a solution for such parallel analysis using the supercomputer, supervised by the KASKADA platform, which with the conjunction with immerse 3D visualization techniques can be used to solve problems such as pulsar detection and chronometric or oil-spill simulation on the sea surface.

Introduction. Studies often suggest hypoxemia is an important factor for sodium retention in chronic obstructive pulmonary disease (COPD), although hypercapnia is also associated with sodium retention in these patients. Hence, we have presented the major role of PaCO2 in edema due to COPD.

Method. COPD patients who were hospitalized due to exacerbation were enrolled in the study and divided into two groups: with and without edema. Exclusion criteria included primary hepatic diseases, nephrotic syndrome and other renal diseases, left heart failure, or using drugs that would interfere with these organs or endocrine function. Data were coded and analyzed by SPSS software. Arterial blood gas variables including bicarbonate, pH, and PaO2, PaCO2 and O2 saturation, and FEV1, FVC, FEV1/FVC were measured and compared between the groups.

Results. No significant difference was found between the averages of bicarbonate, pH, PaO2, O2 saturation, FEV1, FVC and FEV1/FVC in COPD in the two groups. PaCO2 levels were significantly higher in patients with edema, compared to those without edema (p = 0.05). A reverse and significant correlation between PaCo2 and FEV1 levels (p = 0.03) (r = −0.501) was observed in patients with edema.

Conclusion. This study suggests that hypercapnia is a major factor in causing edema in COPD patients compared to hypoxemia.
Acute Atherothrombotic Disease and Severe Bleeding: A Difficult Clinical Presentation in Medical Practice

Published: October 2015

Management of antithrombotic therapy in elderly patients with unstable atherothrombotic disease and increased risk of bleeding is a major clinical challenge. We report the case of a 79 year-old diabetic man with rheumatoid arthritis on both oral corticosteroids and NSAID therapy with mild renal dysfunction, who presented to our hospital because of disabling claudication. Prior to admission he had several episodes of TIA. He also had recurrent small rectal bleeding and mild anemia attributed to his long-standing hemorrhoid disease. Angiography showed a sub-occlusive left internal carotid artery stenosis associated with a significant LAD stenosis and complex peripheral artery disease. Cataclysmic bleeding and hemorrhagic shock occurred in the third day post admission. Withdrawal of all antithrombotic treatment, blood transfusion and emergency sigmoidectomy were performed for bleeding colonic diverticulosis. Subsequently antiplatelet therapy was reinitiated and the patient successfully underwent left carotid artery endarterectomy and LAD stenting. He was discharged from hospital on the 21st day post admission and is doing well at 24 months follow-up.

A 78-year-old Caucasian man was admitted in the Department of Neurology for visual disturbances, started two days before. The next day the patient experienced headache, fever and gait disturbances. He had hypertension, diabetes mellitus, an ischemic stroke 13 years ago, longstanding seronegative rheumatoid arthritis (17 years), polynodular goiter, right ischio-pubian fracture and right femoral vein thrombosis a year ago due to a car accident, since he is treated with oral anticoagulants associated to antiaggregant, hypotensors, statin and oral antidiabetics. The neurologic examination had evidenced nuchal rigidity, left homonymous hemianopsia, left central facial palsy, ataxia of the inferior limbs with wide-based gait, achilean reflexes abolished bilaterally, bilaterally abolished plantar reflexes, ideomotor apraxia, dysarthria, hypoprosexia, and preserved consciousness patient. A non-contrast cerebral CT scan had shown right temporal and parieto-occipital intraparenchymatous hemorrhages, a right frontal sequelar lesion, multiple old lacunar infarcts, cortical atrophy. Laboratory findings included an inflammatory syndrome, absence of rheumatoid arthritis positive serology, normal coagulogram, an elevated proteinuria. The cerebral IRM performed on the seventh day of hospitalisation was suggestive for subacute right parietal hemorrhage, old cerebral infarction in the right anterior cerebral artery area, old lacunar infarcts and cerebral atrophy. The anticoagulant and antiaggregant treatment was stopped after a generalized tonic-clonic seizure occurred. Antiedematous, hypotensor, anticonvulsivant, beta-blocker, and symptomatic treatment was started, while the antidiabetic treatment was continued. All symptoms remitted. Arguments for amyloid angiopathy in our patient are previous non-cardioembolic ischemic stroke and a chronic inflammatory disease-rheumatoid arthritis in his personal medical history.
