Authors: Blé Gamaliel , Loreto-Hernández Iván
Published: March 2021

The conditions to have a stable limit cycle by an Andronov–Hopf bifurcation in a tritrophic model are given. A generalized logistic growth function for the prey is considered, and a general family of functional responses, including the Holling type, are taken for the predators. Some results obtained in previous works for tritrophic models, which consider logistic growth in the prey and Holling functional responses, are generalized.
Severe hypercalcemia in an infant with unbalanced translocation of chromosomes 2 and 8: a possible contribution of 2p duplication
Authors: Bhat Jayalakshmi Narayan , Mock Brittany , Alaqeel Aqeel , Dewoolkar Aditya , Gomez Ricardo
Published: March 2021

Objectives

We report an uncommon case of severe hypercalcemia in an infant with unbalanced translocation of chromosomes 2 and 8 with 2p duplication. After ruling out all the possible etiologies of hypercalcemia, we speculated a potential contribution of 2p duplication involving 225 genes.

Case presentation

An 11-month old female infant with global developmental delay, failure to thrive (FTT), hypotonia, amblyopia, constipation, and recent onset emesis was admitted to the hospital after an incidental diagnosis of severe hypercalcemia. Labs revealed normal serum phosphate, serum 25 (OH) vitamin D levels, and low serum parathyroid hormone (PTH) level. Elevated urinary calcium to creatinine ratio ruled out the possibility of hypocalciuric hypercalcemia. Endocrinological evaluations, including thyroid function test, Adrenocorticotropic hormone (ACTH), Cortisol, Insulin like growth factor 1 (IGF-1) were all normal. Transient elevation of parathyroid hormone related peptide (PTHrP) level was noted, but skeletal survey, chest X-ray and lab values including low 1,25 (OH)2 cholecalciferol, lactate dehydrogenase (LDH), uric acid (UA), erythrocyte sedimentation rate (ESR) excluded granulomatous diseases and malignancies. Further evaluation with chromosomal microarray (CMA) and whole exome gene sequencing (WES) showed an unbalanced chromosomal translocation with 2p duplication involving 225 genes. The infant showed an improvement with medical management.

Conclusions

2p duplication syndrome is a rare syndrome characterized by developmental delay, feeding problems, FTT, hypotonia, constipation, and unusual facial features as noted in our case. However, hypercalcemia has been only reported once earlier in 2p duplication syndrome, which was the presenting feature of our case. We attributed this genetic syndrome as an underlying etiology for hypercalcemia after ruling out all the common potential causes of hypercalcemia.

Objectives

To investigate the effect of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on fetal Doppler parameters.

Methods

This was a prospective case-control study conducted in Ankara City Hospital with confirmed SARS-CoV-2 infected pregnants between August 1, 2020 and October 1, 2020. There were 54 COVID-19 confirmed pregnant women and 97 age-matched pregnant women as a control group between 28 and 39 weeks. Infection was confirmed based on positive real-time polymerase-chain reaction results. Demographic features, uterine artery (right, left), umblical artery, middle cerebral artery, ductus venosus, cerebro-placental ratio, and cerebral-placental-uterine ratio Doppler parameters were investigated in both groups.

Results

Two groups were similar in terms of demographic features and no difference was found for fetal Doppler parameters.

Conclusions

COVID-19 seems to have no adverse effect on fetoplacental circulation in mild and moderate patients during the acute phase of the infection.

Authors: Ren B. , Dang Y. , Gan F. J. , Yang P.
Published: March 2021

This paper describes the computational fluid dynamics (CFD) methodology to simulate the boiling flow in a typical Pressurized Water Reactor (PWR) 5 ⨯ 5 rod bundle. The method includes the Eulerian-Eulerian two-fluid model coupled with the improved wall heat partitioning model. The NUPEC PWR Subchannel and Bundle Test (PSBT) International Benchmark are used for validation. The simulated surface averaged void fraction agree well with the experimental data, which indicate the promising application of the present method for modeling the boiling flow in the fuel rod bundle. The main emphasis of current research has been given to the analysis of the phase distribution around and downstream the spacer grid, the effect of the spacer grid structure, including the mixing vanes, the springs and the dimples on the void fraction distribution is investigated. The findings can contribute to a better understanding of three dimensional flow boiling characteristics and can be used to assist in optimizing the spacer grid.
Investigation of level density parameter dependence for some 233U, 235U, 237U, 239U, 249Cf, 251Cf, 237Pu and 247Cm nuclei in neutron fission cross sections with the incident energy up to 20 MeV
Authors: Sönmez Ö. , Karaman O.
Published: March 2021

Level density models have increasing importance to gain more in-depth into the nature of nuclear reactions. Many novel and advanced medical application use radioisotopes, which are produced with nuclear reactions. In this study, the effect of the level density parameters of the nucleus on the cross sections of neutron-fission reactions for 233U, 235U, 237U, 239U, 249Cf, 251Cf, 237Pu and 247Cm nuclei were investigated for up to 20 MeV neutrons. TALYS 1.8 software was used to calculate the cross-sections of neutron-fission reactions for different level density parameters. The calculations were compared with the EXFOR nuclear data library and the level density parameters, and the closest fit were searched. As outputs of the study, the effect of selection of level density parameter on cross section calculations was observed. The theoretically obtained data were compared with the experimental data taken from the literature. The results are presented graphically for better interpretation.
Managing interpersonal discourse expectations: a comparative analysis of contrastive discourse particles in Dutch
Authors: van Bergen Geertje , Hogeweg Lotte
Published: March 2021

In this article we investigate how speakers manage discourse expectations in dialogue by comparing the meaning and use of three Dutch discourse particles, i.e.wel,tochandeigenlijk,which all express a contrast between their host utterance and a discourse-based expectation.The core meanings oftoch, welandeigenlijkare formally distinguished on the basis of two intersubjective parameters: (i) whether the particle marks alignment or misalignment between speaker and addressee discourse beliefs, and (ii) whether the particle requires an assessment of the addressee’s representation of mutual discourse beliefs. By means of a quantitative corpus study, we investigate to what extent the intersubjective meaning distinctions betweenwel,tochandeigenlijkare reflected in statistical usage patterns across different social situations. Results suggest thatwel,tochandeigenlijkare lexicalizations of distinct generalized politeness strategies when expressing contrast in social interaction. Our findings call for an interdisciplinary approach to discourse particles in order to enhance our understanding of their functions in language.
Prior Residence and Immigrant Voting Rights
Authors: Goppel Anna
Published: March 2021

Although the moral foundations of voting rights regulations have been the subject of widespread scrutiny, there is one aspect of the debate which has gone largely unquestioned and is currently accepted in every state’s actual voting rights regulations. This is the requirement of prior residence, which stipulates that immigrants are granted the right to vote only once they have lived in the host country for a certain period of time. It is this requirement I call into question in this paper. Taking up the most plausible justifications for this requirement, I aim to put substantial pressure on its moral acceptability by arguing that it is not directly grounded by any of the principles that are currently defended as a means to determine thedemos, nor a proxy for some other morally relevant feature, nor a warrantor for abilities held to be significant for the right to vote.

Pulp pumping efficiency II – Designing of a pulp pump
Authors: Zhang Qihua , Kang Shun , Xie Zhiang , Cao Li , Yan Zhaoxu , Zhang Weidong
Published: March 2021

Based on the loss model of pulp pump set up in the I part of this research, an efficient designing method is proposed by taking account of the influences of head reduction by small blade number, leakage loss via tip clearance, and erosion-corrosion wears in pumps separately. Further, a two-stage optimal designing approach was proposed to tackle the oversized design. The pump designing was performed by coupling with a CFD-based optimization procedure. An efficiency increase of near 10 % was achieved on the pump model validated in laboratory. It was proved that performance could be improved by increasing the impeller blade width and enlarging the impeller blade outlet angle. It was further shown that the erosion-corrosion wear in pulp pump was relatively lighter when compared to particle-impingement wear in slurry and sewage pump. Adoption of composite material showed potential in energy-saving in the pumping system.
Effective ion pathways and 3D conductive carbon networks in bentonite host enable stable and high-rate lithium–sulfur batteries
Authors: Wu Lian , Dai Yongqiang , Zeng Wei , Huang Jintao , Liao Bing , Pang Hao
Published: March 2021

Fast charge transfer and lithium-ion transport in the electrodes are necessary for high performance Li–S batteries. Herein, a N-doped carbon-coated intercalated-bentonite (Bent@C) with interlamellar ion path and 3D conductive network architecture is designed to improve the performance of Li–S batteries by expediting ion/electron transport in the cathode. The interlamellar ion pathways are constructed through inorganic/organic intercalation of bentonite. The 3D conductive networks consist of N-doped carbon, both in the interlayer and on the surface of the modified bentonite. Benefiting from the unique structure of the Bent@C, the S/Bent@C cathode exhibits a high initial capacity of 1,361 mA h g−1 at 0.2C and achieves a high reversible capacity of 618.1 m Ah g−1 at 2C after 500 cycles with a sulfur loading of 2 mg cm−2. Moreover, with a higher sulfur loading of 3.0 mg cm−2, the cathode still delivers a reversible capacity of 560.2 mA h g−1 at 0.1C after 100 cycles.

Published: March 2021

In this analysis, the baffling method is used to increase the efficiency of channel heat exchangers (CHEs). The present CFD (computational fluid dynamics)-based work aims to analyze the constant property, steady, turbulent, Newtonian, and incompressible fluid flow (air), in the presence of transverse-section, arc-shaped vortex generators (VGs) with two various geometrical models, i.e., arc towards the inlet section (called arc-upstream) and arc towards the outlet section (called arc-downstream), attached to the hot lower wall, in an in-line situation, through a horizontal duct. For the investigated range of Reynolds number (from 12,000 to 32,000), the order of the thermal exchange and pressure loss went from 1.599–3.309 to 3.667–21.103 times, respectively, over the values obtained with the unbaffled exchanger. The arc-downstream configuration proved its superiority in terms of thermal exchange rate by about 14% than the other shape of baffle. Due to ability to produce strong flows, the arc-downstream baffle has given the highest outlet bulk temperature.
Adsorption and separation behavior of palladium(II) from simulated high-level liquid waste using a novel silica-based adsorbents
Authors: Wu Hao , Osawa Naoki , Kubota Masahiko , Kim Seong-Yun
Published: March 2021

Aiming at selective adsorption and separation of Pd(II) in nitric acid solution, a hybrid soft N and hard O donor adsorbent (TAMIA-EH+TOA)/SiO2–P (P = Polymer) was successfully synthesized. The adsorption performances of (TAMIA-EH+TOA)/SiO2–P adsorbent towards Pd(II) were systematically investigated as a function of contact time, effect of concentration of nitric acid, effect of temperature etc. Adsorption speed of Pd(II) was fairly fast and can reach equilibrium state within only 0.5 h. The distribution coefficient of Pd(II) was more than 103 when [HNO3] = 0.1. Though it decreased gradually with an increase in the concentration of HNO3, the adsorption selectivity of (TAMIA-EH+TOA)/SiO2–P adsorbent towards Pd(II) was still significant than other co-existing metal ions in the whole HNO3 range from 0.1 to 5 M. The adsorption isotherm of Pd(II) onto (TAMIA-EH+TOA)/SiO2–P adsorbent fitted well with Langmuir adsorption model but Freundlich isotherm model. The calculated results of adsorption thermodynamic parameters indicated that the adsorption process of Pd(II) was exothermic and happened in a natural way. Furthermore, the separation chromatography experiment by utilizing (TAMIA-EH+TOA)/SiO2–P adsorbent packed column was carried out. Based on the results of plotted elution curves, it was found that the successful recovery of Pd(II) (96.27%) was achieved by eluting with thiourea solution.
On the evolution of acceleration discontinuities in van der Waals dusty magnetogasdynamics
Authors: Srivastava Shobhit Kumar , Chaturvedi Rahul Kumar , Singh Lal Pratap
Published: March 2021

The article presents the study of the evolutionary behavior of plane and cylindrically symmetric acceleration discontinuities along the characteristic path under the effect of dust particles in a non-ideal magnetogasdynamic flow. Implications regarding the propagation of disturbances in planar and cylindrically symmetric flows have been shown. Using the characteristics of the governing quasilinear system as a reference coordinate system, we transform the fundamental equations and find the solution. It is explored how the dust particles, along with the nonideal parameter, will influence the steepening or flattening of the propagating waves in magnetic and nonmagnetic cases. The transport equation leading to the evolution of acceleration discontinuities is determined, which provides the relation for the occurrence of shock. The impact of non-idealness of the gas and dust on the evolutionary process of propagating waves for the magnetic and nonmagnetic cases are discussed. The comparison between the flow patterns and distortion of the propagating waves for planar and cylindrically symmetric flows is demonstrated under the various parameter effects.
Mapping (as) Resistance: Decolonizing↔Indigenizing Journalistic Cartography
Authors: Lowan-Trudeau Greg
Published: March 2021

This article considers journalistic cartography in relation to socioecological disasters in Indigenous territories and associated resistance movements. The authority of Western-style maps as presented in news media and elsewhere is often taken for granted—colonial cartography exerts powerful, typically unquestioned, influence upon peoples’ understandings of cultural geographies and associated land-based relationships. Such dynamics are particularly germane to consideration of Indigenous environmental and territorial concerns and associated resistance actions across Turtle Island / North America and elsewhere around the world. I present Indigenous mapping traditions and contemporary cartographic interventions as inspiring counterexamples for shifting public narratives and understanding of Indigenous territories, environmental knowledge, and related issues within news media and beyond.
The Architectural Origins of the Parthenon Frieze
Authors: Senseney John R.
Published: March 2021

In light of evidence for substantial alterations to the forms and spatial configurations of the Parthenon during the construction process, John R. Senseney interrogates the origins of the celebrated Ionic frieze, with its continuous figural procession sculpted by the workshop of Pheidias, in The Architectural Origins of the Parthenon Frieze. Emphasizing ancient planning methods, Senseney argues that the Parthenon’s builders settled on an Ionic frieze in response to the rare decision to include prostyle porches. To contend with formal complexities, the builders engaged in exploratory design within the construction of the east peristyle, east porch, and pronaos, the results of which then guided construction elsewhere in the superstructure. Comparative analysis supports Senseney’s argument that the Ionic form of the Parthenon frieze arose not from the sculptural program but rather in response to issues of alignment within the pronaos and as part of a fluid process of modeling that coalesced in an aesthetic focused on formal continuity and integration.
Economic Incentive to Ignore the Environment
Authors: Henderson Kent E.
Published: March 2021

The world environmental regime has influenced government policy and improved environmental conditions around the globe, but its influence on governance is sometimes decoupled from, or loosely connected with, actual practice. This article examines the influence of the environmental regime on foreign aid and proposes that economic incentive, in the form of FDI, is a source of decoupling between aid donors’ stated environmental goals and actual aid commitments. Using a three-dimensional panel design (donor × recipient × year), I test allocations of environmental protection and fossil fuel aid in a two-stage process where first the aid recipient is chosen, and then the aid amount. I find that although donor and recipient environmental regime integration are associated with higher likelihood of exchanging environmental aid, other factors (donor/recipient GDP, recipient democracy, etc.) determine the amount of aid. Regime integration does not reduce the likelihood of exchanging fossil fuel aid, but donor regime integration is associated with giving less fossil fuel aid, contingent on the donor’s level of FDI in the recipient nation. I conclude that the world environmental regime and the global economy exert contradictory pressures on aid organizations that result in policy–practice decoupling. The world environmental regime, therefore, has only been partially successful in improving foreign aid, and its effect is constrained by donors’ economic incentive to ignore environmental norms.
Coming to Critical Disability Studies: Critical Reflections on Disability in Health and Social Work Professions
Authors: Burghardt Madeline , Edelist Tracy , Fudge Schormans Ann , Yoshida Karen
Published: March 2021

This paper describes how four ‘helping’ professionals came to embrace and teach critical disability studies (CDS) perspectives rather than biomedical approaches to impairment and disability that traditionally inform those professions (occupational therapy, physiotherapy, social work, and speech-language pathology). Sharing examples from our experiences, we describe how we came to question the normative, ableist assumptions of our professional disciplines. We then briefly outline literature demonstrating how critical approaches have been incorporated into professional research and practice and discuss possible obstacles and tensions in adopting more widespread critical approaches into professional spaces. We conclude by suggesting that continued development of connections among scholars and activists within CDS, rehabilitation and social work, and the community, is necessary to ensure that intersectional critical perspectives in relation to disability become a core component of professional training programs.

Thermo-Optical Effects in Plasmonic Metal Nanostructures
Authors: Yeshchenko O.A. , Pinchuk A.O.
Published: March 2021

The effects of the temperature on the surface plasmon resonance (SPR) in noble metal nanoparticles at various temperatures ranging from 77 to 1190 K are reviewed. A temperature increase results in an appreciable red shift and leads to a broadening of the SPR in the nanoparticles (NPs). This observed thermal expansion along with an increase in the electron-phonon scattering rate with rising temperature emerge as the dominant physical mechanisms producing the red shift and broadening of the SPR. Strong temperature dependence of surface plasmon enhanced photoluminescence from silver (Ag) and copper (Cu) NPs is observed. The quantum photoluminescence yield of Ag nanoparticles decreases as the temperature increases, due to a decrease in the plasmon enhancement resulting from an increase in the electron-phonon scattering rate. An anomalous temperature dependence of the photoluminescence from Cu nanoparticles was also observed; the quantum yield of photoluminescence increases with the temperature. The interplay between the SPR and the interband transitions plays a critical role in this effect. The surface-plasmon involved laser heating of a dense 2D layer of gold (Au) NPs and of Au NPs in water colloids is also examined. A strong increase in the Au NP temperature occurs, when the laser frequency approaches the SPR. This finding supports the resonant plasmonic character of the laser heating of metal NPs. The sharp blue shift of the surface plasmon resonance in colloidal Au NPs at temperatures exceeding the water boiling point indicates the vapor-bubble formation near the surface of the NPs.

Chronic Kidney diseases: Role of Vitamin-K and Vitamin-D
Authors: Varapete Vinod Kumar , B N Ravindra , S Shaji Jerin , Mulla Yaseen , P Jose Jiss , Dominic Alex , Paul Prolay , Ghosh Sayantan
Published: March 2021

Chronic kidney disease is the most common form of kidney disease and high blood pressure is the most common cause the pressure on the glomeruli increases due to high blood pressure which can prove to be very dangerous. Lack in VITAMIN D isn't restricted to the dynamic chemical, calcitriol (25-hydroxycholecalciferol) is likewise insufficient in many patients with constant kidney sickness (CKD), free of their fundamental renal capacity. Diminishes in calcitriol happen generally right off the bat in the movement of kidney illness and may originate before the increment in PTH. These progressions in calcitriol and PTH add to the upkeep of moderately ordinary serum and calcium fixations until the glomerular filtration rate (GFR) diminishes to <20–25%; nonetheless, the outcome is the potential advancement of bone and vascular sickness. Vitamin K intake and long-term vitamin K status are expressed by a high percentage of undercarboxylated OC (uOC). Vitamin D, which is needed for uOC development, and parathyroid hormone (PTH), which is often elevated in patients with CKD, are also affected by osteocalcin levels. Therefore, elevated serum uOC is present in patients with chronic kidney disease (CKD) with hyperparathyroidism, but this does not generally mean that they are deficient in vitamin K.

The objective: to analyze the approaches to delivery of women with pregnancy after the application of curative programs of assisted reproductive technologies (ART). Patients and methods. In the process of the study, the approaches to the choice of the method of delivery of women after the application of ART were studied and analyzed. To achieve this goal, women were divided into two groups: the 1-st group – women after ART (2005-2009), whose delivery was performed in a conventional way, their number was 132 women; the 2-nd group – women after ART (2010-2014), whose delivery was performed according to the developed algorithm, their number was 162 women giving birth. Results. The comparative characteristics of the two groups established that the delivery of women after the use of assisted reproductive technologies (ART), which gave birth through the natural birth canal, in 70% ended with physiological labor. This trend indicates that the delivery of women after ART through the natural birth canal is one of the concepts for a significant reduction in the percentage of cesarean section (CS) in the hospital. Conclusion. To determine the optimal method of delivery in patients after ART, first of all, it is necessary to take into account the etiologic factor of infertility and the features of the course of pregnancy, and not the presence of an ART program in the history, as indications for the planned CS. Key words: auxiliary reproductive technologies, cesarean section.

“Philosophy of the Name” by S. Bulgakov (Cogytological Interpretation)
Authors: Fefilov Alexander
Published: March 2021

The paper focuses on the interpretation of the basic linguophilosophical views of S.N. Bulgakov set out in his work Philosophy of the Name (1920, 1953). Philosopher and theologian S.N. Bulgakov expresses opinions on the essence of a word from the point of view of cogitology. The author interprets S.N. Bulgakov's explanations of such integrative terms as "word-thought", "logos" and "sound word". S.N. Bulgakov declares that a word is equated to an enlightened logos as a unity of words and thoughts, words and deeds, words and things. According to the philosopher, the meaning of a word is an idea embodied in the sound form of a word. In speech, the word-meaning turns into a word-thought. A thought comes true due to a speech-word. Language as a means of expression exists in its complete form long before the act of its designation. A thing is revealed in its name. The article also reveals the views of S.N. Bulgakov on words from the root, verbs-linker and pronouns that do not have their own content. The author believes that the results of the analysis in the article can enrich our ideas about language as an instrument of naming, designation and expression (cognitive aspect), and as a means of speech activity (communicative aspect).

In recent years, rapid urbanisation has caused a large volume of construction and demolition waste in China. Although China has introduced some documents and policies to manage the waste, these documents are not operable or detailed enough to guide the practice further. It is of great importance to analyse critical success factors (CSFs) that could contribute to the successful development of construction and demolition waste management in China. A survey questionnaire was delivered to 150 participants, with 121 responses returned. Eighteen CSFs were identified and evaluated. The results showed that five factors – namely, ‘polluter-pays principle’, ‘subsidies for recycling activities’, ‘waste minimisation at the planning stage’, ‘value-added tax deduction’ and ‘penalties on violations’ – were considered the most important factors. Additionally, differences among the perspectives of three groups of related stakeholders (researchers, industry practitioners and government officers) on the criticality of the 18 CSFs were investigated. ‘City plan for land use’ was considered to have significant disagreement among researchers and government officers. However, the perceptions of industry practitioners were significantly different from those of researchers and government officers. The disagreements might be caused by the different interests, needs and objectives of related stakeholders. The findings of this study will likely prompt the policymakers in China to consider relevant CSFs to enhance the performance of construction and demolition waste management.
Media Image of a Contemporary Writer via Interpretation of Their Texts (by the Example of Inwerviews with Dina Rubina's)
Authors: Zueva Galina
Published: March 2021

This paper studies the media image of a modern Russian writer Dina Rubina basing on her portrait (face-to-face) interviews and subject-related portrait interviews in various contemporary Russian and pro-Russian media: newspapers, magazines, radio, TV, and the internet-media. Growing interest to modern writers in the media environment and to interaction between the writer and the reader via mass media determines the topicality of the research. The study object is a public figure from the literary community. In this relation, the author finds it necessary to distinguish between the notions "media image", "imagery", and "image". The interviews with Dina Rubina are analyzed in the context of the form and contents of her works, which helps to identify and fix some personal intentions of the writer. The author studies the writer's media image basing on the theory of archetypes, as well as their influence on Dina Rubina's and her interviewers' professional behavior. The specific character of the questions asked to the writer prove the importance of the archetype of the creator and its dominance among the contributory archetypes, namely, those of the Harlequin and the mother. Special attention is paid to the gender aspect of a modern writer's media image, which is quite significant for Dina Rubina and her readers.
Trends in State Regulation of Russian Mass Media: a Legal Aspect
Authors: Pankeev Ivan , Timofeev Alexey
Published: March 2021

The article deals with major trends in state regulation of Russian media landscape in the period 2017-2020, which features a large amount of fake news, extremist publications and other information harmful for the people and the society. The authors analyze the key measures taken by the state in order to protect the population from such information and diminish its negative effect, define the problems and difficulties that journalists and Internet-users face, and propose ways of addressing the problems. The article focuses on legal aspects of the governmental bans and regulatory policy as, in the authors opinion, they are primary to the other measures (economic, technological, etc.). Special attention is paid to the state legislative response to such threats as fake news, suicide, drug abuse, extremist or terrorist propaganda, and foreign agents financial impact on Russian media. The research involved an analysis of media reports on the relevant issues, as well as a study of the recent changes in the legislation concerning media landscape and results of other researches in this field. The authors infer that there are two major trends in the state regulation: one is liberalization of privacy laws for media landscape, and the other is harsher punishments for spreading extremist information, fake news and other state abusive content. However, such control should not be always viewed as negative.

The issues of assessing the fairness and efficiency of the distribution of the total income of society between different groups of the population have attracted attention of scientists for a long time. They became most relevant at the end of the 19th – beginning of the 20th centuries in connection with the intensive stratification of countries with various political and social systems caused by the intensive development of the economy, science and technology. The Lorenz function and the Lorenz curve, as well as the Gini index, are commonly used for theoretical research and applications in the economic and social sciences. These tools were originally introduced to describe and study the inequality in the incomes and wealth distribution among a given population. Nowadays they have found wide application in such fields as demography, insurance, healthcare, the risk and reliability theory, as well as in other areas of human activities. In this paper we present the properties of the Lorentz function and various representations of the Gini index, systematize the analytical results for uniform, exponential, power-law (types I and II) and lognormal distributions, as well as for the Pareto distribution (types I and II). Additionally, the issue of estimating inequality based on the Pietra index and its relationship with the Lorentz function was studied. Nonparametric estimates of the Lorentz function and the Gini index based on a sample from the corresponding distribution are considered. Strict consistency and asymptotic unbiasedness of these estimates are shown under certain conditions for the initial distribution with an increase in the sample size. On the basis of the method of linearization of estimates, the asymptotic normality of the empirical Lorentz function and the empirical Gini index is determined.

A brief comparative review of English-language literatures of Australia and New Zealand is given in the article. The aim of the article is to highlight the similarities and differences at the stages of the literary process development from the point of view of postcolonial studies. The historical genesis specificity of the region and the uniqueness of national identity formation at the juncture of colonial and colonized cultures stipulate the definition of Australia and New Zealand as settler societies. Tasks needed to be resolved are to disclose the notion “settler societies”, to determine common characteristics of the studied national literatures as postcolonial ones, to give their comparative outline, to make a textual analysis of a number of literary works which are indicative for each stage of the literary process development. In the course of the study, the authors refer to a comparative historical method of scientific enquiry to highlight similarities in the literary process development and the degree of influence of metropolitan literature on it. They also use a sociological method to estimate the impact of the settler societies development on the literary process and a hermeneutic interpretative method in textual analysis to interpret the transformation of a typical hero at various stages of the literary process in Australia and New Zealand. The article is divided into theoretical and practical parts. In the theoretical part, the authors define “settler societies”, overview the place of “settler” countries in the postcolonial space, and note factors allowing to review the national literatures comparatively as postcolonial ones. In the practical part, the authors characterize three stages of the literary process development observed in the national literatures of Australia and New Zealand, conduct an interpretative analysis of the works in which the prolific features of a typical hero are shown. On conducting the research the authors come to the following conclusions. The national literatures of Australia and New Zealand are under the influence of the metropolitan culture and literaturel, but the relation started to loosen at a contemporary stage of the literary process development due to the formation of the national identities of Australians and New Zealanders. The impact of colonized indigenous peoples’ cultures on the literary process defines the difference between the national literatures. For the countries, the national identity formation is characteristic in the cultural sphere, which makes the further study of identification processes presentation in literary text promising.

Teknolojik ve ekonomik ilerlemeyle birlikte sınırların ortadan kalkması, müşteri taleplerinin içerikleri ve hacimlerinin sürekli bir şekilde değişmesini ve beraberinde işletmelerin bu değişimlere hızlı cevap verebilmesi gerekliliğini ortaya çıkarmıştır. Bu ihtiyaç, işletmeleri kitlesel üretim sistemlerinin hızını ve esnek üretim sistemlerinin de esneklik kabiliyetini birlikte karşılayacak modern üretim sistemlerine yöneltmiştir. Bu üretim sistemlerinden bir tanesi de Japonya’da 90’lı yıllarda elektronik sektöründe kullanılmaya başlanan seru üretim sistemleridir. Bu sistemler, geleneksel montaj hatlarını seru adı verilen hücrelere bölerek, bir ürünün üretimindeki tüm görevlerin tek ya da birden fazla yüksek yetenekli çalışan tarafından gerçekleştirildiği sistemlerdir. Bu çalışmanın amacı, kitle üretimin hızını ve esnek üretimin ürün çeşitliliği sağlama kapasitesini karşılayan seru üretim sistemi için optimum seru yükleme planları elde etmektir. Bu nedenle, seru üretim sistemlerinde karşılaşılan problemlerden olan seru yükleme problemi ele alınmıştır. Belirli bir seru tasarımına ait optimal işçi ve iş yükleme planını elde etmeye yönelik karışık tamsayılı yeni bir matematiksel model ve bir mat-sezgisel algoritma önerilmiştir. Modelden ve sezgisel yöntemden elde edilen sonuçların etkinliği, literatürden alınan gerçek bir uygulama veri setiyle karşılaştırmalı olarak gösterilmiş karşılaştırma sonucunda elde edilen seru yükleme planlarının etkin olduğu gözlemlenmiştir.
Bir ters-basamak üzerindeki engellerin etrafındaki akışın sayısal olarak incelenmesi
Authors: BAYRAKTAR Seyfettin
Published: March 2021

Bu çalışmada, bir ters-basamak üzerine konumlandırılmış kare, daire ve eşkenar üçgen kesitli prizmatik engellerin akım alanı üzerindeki etkileri sayısal olarak incelenmiştir. Türbülanslı, üç-boyutlu, daimi ve sıkıştırılamaz olarak kabul edilen akış, modifiye k-omega türbülans modeli kullanılarak çözülmüştür. Elde edilen sonuçlar, boyutsuz sürtünme ve boyutsuz basınç katsayıları ile boyutsuz ayrılmış akış bölgesi cinsinden sunulmuşlardır. Çalışmada engellerin geometrik şekillerinin dışında, yüksekliklerinin (h) ilgili değişkenler üzerindeki etkileri basamak yüksekliği (H) ile boyutsuzlaştırılarak H/h=0,125; 0.25; 0,5 ve 1 için sunulmuştur. Üzerinde engel bulunmayan ters-basamak için elde edilen sayısal sonuçlar, Driver and Seegmiller, 1985`in deneysel verileri ile karşılaştırılarak sayısal modelin doğruluğu gösterilmiştir. Üzerinde engel olmayan ters-basamak üzerindeki akış göz önüne alındığında, sadece engellerin varlıklarının değil, aynı zamanda kesit şekillerinin de sürtünme katsayısı, basınç katsayısı ve boyutsuz ayrılmış akış bölgesi uzunluğu üzerinde etkilerinin olduğu görülmüştür. Ters-basamak üzerine konulmuş engellerin kesit geometrisi fark etmeksizin herhangi bir engelin varlığının, ayrılmış akış bölgesi uzunluğunu artırdığı, ancak en uzun bölgeye, eşkenar üçgen kesitli prizma kullanıldığında ulaşıldığı saptanmıştır. Engel yüksekliğinin ayrılmış akış bölgesi üzerindeki etkisinin H/h=0,25 ten sonra oldukça düşük olduğu belirlenmiştir.
