Hardware in the Loop Simulation and Control Design for Autonomous Free Running Ship Models
Authors: Dubey Awanish Chandra , Subramanian Anantha V
Published: July 2020

This paper presents an hardware-in-the-loop (HIL) simulation system tool to test and validate an autonomous free running model system for ship hydrodynamic studies with a view to verification of the code, the control logic and system peripherals. The computer simulation of the plant model in real-time computer does not require the actual physical system and reduces the development cost and time for control design and testing purposes. The HIL system includes: the actual programmable embedded controller along with peripherals and a plant model virtually simulated in a real-time computer. With regard to ship controller design for ship model testing, this study describes a plant model for surge and a Nomoto first order steering dynamics, both implemented using Simulink software suit. The surge model captures a quasi-steady state relationship between surge speed and the propeller rpms, obtained from simple forward speed towing tank tests or derived analytically. The Nomoto first order steering dynamics is obtained by performing the standard turning circle test at model scale. The control logic obtained is embedded in a NI-cRIO based controller. The surge and steering dynamics models are used to design a proportional-derivative controller and an LQR controller. The controller runs a Linux based real-time operating system programmed using LabVIEW software. The HIL simulation tool allows for the emulation of standard ship hydrodynamic tests consisting of straight line, turning circle and zigzag to validate the combined system performance, prior to actual for use in the autonomous free-running tests.

Authors: Tang Jiayu , Li Xiangmin , Dai Jinjin , Bo Ning
Published: July 2020

As a challenging and highly complex problem, the trajectory planning for unmanned combat aerial vehicle (UCAV) focuses on optimising flight trajectory under such constraints as kinematics and complicated battlefield environment. An online case-based trajectory planning strategy is proposed in this study to achieve rapid control variables solution of UCAV flight trajectory for the of delivery airborne guided bombs. Firstly, with an analysis of the ballistic model of airborne guided bombs, the trajectory planning model of UCAVs is established with launch acceptable region (LAR) as a terminal constraint. Secondly, a case-based planning strategy is presented, which involves four cases depending on the situation of UCAVs at the current moment. Finally, the feasibility and efficiency of the proposed planning strategy is validated by numerical simulations, and the results show that the presented strategy is suitable for UCAV performing airborne guided delivery missions in dynamic environments.

Authors: Vala Masoud Mohamadi , Bayat Yadollah , Bayat Mohammad
Published: July 2020

An energetic binder epoxy poly glycidyl nitrate (e-PGN) with a molecular weight of about 1244 gr/mol was synthesised via end modified poly glycidyl nitrate (PGN) is presented in the paper. This structure was characterised by the number of epoxy groups, infrared spectroscopy, and nuclear magnetic resonance. The thermal degradation behavior of e-PGN was studied by thermo gravimetric analysis (TG) and differential scanning calorimetry (DSC) under nitrogen atmosphere at different heating rates. The glass transition temperature (Tg) was measured to determine the compatibility of energetic plasticizer with the binder in the mixture of plasticizer/binder and compared with the results of e-PGN, and initial decomposition temperature in e-PGN was studied using the DSC method. The DSC results showed that the glass transition temperature of a mixture of 20 % Bu-NENA/e-PGN mixture (Tg = −56 °C) was lower than e-PGN (Tg = −37.78 °C) that shows the most compatible plasticizer is Bu-NENA. The activation energy of degradation e-PGN and e-PGN-20% Bu-NENA were calculated with DSC by the model-free methods and compared with the results of AKTS software in version 3.51(2013-07-10). The activation energy of exothermic decomposition of the e-PGN and e-PGN-20% Bu-NENA were calculated by the Kissinger, Flynn–Wall–Ozawa, Starink, and AAdvanced kinetics and technology solutions (Friedman) methods. Finally, the half-life prediction of the e-PGN and e-PGN-20% Bu-NENA were investigated.

Koncepcja federacyjna polskiego rządu jako forma nowego ładu pokojowego w Europie (1939–1945)
Authors: Miszewski Dariusz
Published: July 2020

W czasie II wojny światowej wyszła z koncepcją integracji Europy Środkowej we współpracy z Czechosłowacją. Polska tradycja wolności i pokojowych unii z sąsiednimi narodami była alternatywą dla niemieckiej i radzieckiej jedności Europy Środkowej na drodze przemocy. Polski plan pokojowej i dobrowolnej integracji państw Europy Środkowej miał im przynieść bezpieczeństwo i rozwój oraz regionalną solidarność i niezależność od wrogich i sojuszniczych mocarstw. Stałe spotkania polskiego rządu w Londynie z ośmioma emigracyjnymi rządami państw okupowanych miały doprowadzić do powstania subregionalnych związków państw. Miały być jednym z filarów pokoju i bezpieczeństwa w Europie obok mocarstw. Sprzeciw ZSRR uniemożliwił realizację polskich planów.

Do głównych tendencji w zakresie współczesnej składni funkcjonalnej należy przede wszystkim semantyzacja, która opiera się na przeorientowaniu badań lingwistycznych na zasadzie „od treści do formy”. Aktualność danego badania uwarunkowana jest koniecznością wielowymiarowej analizy korelacji przyimków wtórnych — składników czasowych przyimkowo- rzeczownikowych konstrukcji ze znaczeniem czasu przybliżonego i pośredniego oraz analizy korelacji między pochodnymi przyimkami czasowymi zgodnie ze współczesną nauką. Badanie koncentruje się na formalnej strukturze czasowych przyimkowo-rzeczownikowych temporatywów z uwzględnieniem relacji genetycznychvtomych przyimków czasu, także na wariantach znaczeniowych przez nie realizowanych. Przeprowadzono analizę paradygmatów czteroskładnikowych przyimkowo-rzeczow- nikowych korelatywów ze znaczeniem czasu przybliżonego i pośredniego we współczesnym języku ukraińskim. Stwierdzono, że wtórne przyimki czasowe powodują pojawienie się cech różnicujących we współzależnych przyimkowo-rzeczownikowych strukturach czasowych, dzięki czemu wchodzą w wewnętrzne związki korelacyjne. Specyficzne warianty semantyczne, odcienie stylistyczne i sfera zastosowania są podstawowymi atrybutami różnicującymi przyimkowo- rzeczownikowe konstrukcje z wtórnymi przyimkami czasowymi.
НОВЕЛІСТИКА ВАСИЛЯ ҐАБОРА: ТРАДИЦІЇ Й НОВАТОРСТВО
Authors: ДАШКО НАТАЛІЯ
Published: July 2020

Artykuł poświęcony jest twórczości W. Gabora w kontekście zróżnicowanej gatunkowo i stylistycznie współczesnej ukraińskiej nowelistyki. Celem artykułu jest ukazanie twórczości wspomnianego pisarza w dialektyce tradycji i nowatorstwa. W wyniku dogłębnej analizy można dojść do wniosku, że W. Gabor kontynuuje gatunek klasycznej noweli i jednocześnie eksperymentuje, wprowadzając innowacje nie tylko w obrębie formy, ale i treści. Wczesne utwory prozaika wykazują cechy poetyki modernistycznej. Silnym dramatyzmem i lakonicznością w duchu W. Stefanyka wyróżniają się nowele Щоб не бив бубон, Звір, Швонц (tom Книга екзотичних снів та реальних подій), w których realizowane są główne postulaty ekspresjonizmu — konfrontacja życia i śmierci, tragiczny światopogląd, psychologizm, ważna rola szczegółu artystycznego. W nowelach ze zbioru Про що думає людина pojawiają się cechy impresjonizmu łączące W. Gabora z M. Kociubynskim. Jednocześnie można wyróżnić w powyższym tomie główne cechy współczesnej noweli modyfikowanej, gdy działania wewnętrzne bohaterów wychodzą na plan pierwszy, podobnie jak pogłębiona asocjatywność, metaforyczność, wyobrażenia. Ponadto w stylu W. Gabora można wyróżnić zarówno elementy realistyczne, jak i romantyczne, których połączenie stanowi podstawę fantastycznego realizmu pisarza (nowela Поминки).
УКРАЇНСЬКА РОМАНТИЧНА ПОЕЗІЯ: СИМВОЛІКА ОБРАЗУ КОНЯ
Authors: HAYDUK SVITLANA
Published: July 2020

W artykule został przeanalizowany obraz konia w twórczości ukraińskich poetów romantyków na tle europejskiej tradycji pisania w świetle jego symbolicznych oraz mitologicznych paradygmatów. Podkreśla się, że w ukraińskiej romantycznej poezji symbolika obrazu konia bezpośrednio koreluje z symbolem wolności, ponieważ koń jako obraz poetycki jest „istotą obdarzoną duszą”. Wolność symbolizują jego działania, czyli pęd, dziki galop lub spokojna wędrówka (wiersz Козак Ł. Borowykowskiego, ballada Кінь M. Kostomarowa). Zauważono, że obraz konia działa jako symbol wierności i piękna. Potrafi się wczuć w romantycznego bohatera, przestrzec go przed niebezpieczeństwem (poemat Гайдамаки, ballada Причинна T. Szewczenki, wiersz Козак Ł. Borowykowskiego, До коня W. Zabiły, Украинская дума O. Afanasjewa-Czużbińskiego). Jednak obrazy koni mogą również symbolizować mroczne siły natury. Niosą one jeźdźca w nieznane, ucieleśniają negatywną energię (poemat satyryczny Сон T. Szewczenki).
Conceptions of Truth in Plato’s

Sophist
Authors: Peramatzis Michail
Published: July 2020

The paper seeks to specify how, according to Plato’s Sophist, true statements achieve their being about objects and their saying that ‘what is about such objects is’. Drawing on the 6th definition of the sophist, I argue for a normative-teleological conception of truth in which the best condition of our soul –in its making statements or having mental states– consists in its seeking to attain the telos of truth. Further, on the basis of Plato’s discussion of original and image, his distinction between correct and incorrect image, and the 7th definition, I argue that achieving the telos of truth involves preserving the original’s proportions and appropriate features. The view that Plato’s conception of truth takes statements or mental states to be certain types of image is not ground-breaking. The important contribution of my argument is that it offers a plausible way to understand two recalcitrant claims made by Plato: first, that falsity obtains not only in the region of incorrect images (appearances) but also within correct images (likenesses); second, that some incorrect images are based on knowledge and so could be true.
Kant über die Vollständigkeit der „Tafel der Kategorien der Freiheit“
Authors: Zimmermann Stephan
Published: July 2020

Kant’s repeated statement in the Critique of Pure Reason that the so-called table of judgements and, as a consequence, the table of pure concepts of the understanding or categories, is fully exhaustive is well-known. This ambitious assertion has worried and challenged generations of authors. However, thus far the entire discussion has completely disregarded the fact that in his Critique of Practical Reason Kant undertakes a coordinate venture. For the “Table of the Categories of Freedom”, which he sets out, with only a few explanations, in the “Second Chapter” of the Critique, Kant makes, when looked at more closely, the very same claim to completeness. This article shows that this same claim is made, even though Kant does not state this assertion as explicitly as one might have expected. And it poses the question, which underlying, yet concealed assumptions this view might appeal to. Or is it that Kant has merely failed to provide the evidence in this case?

A distributed cognitive approach in cybernetic modelling of human vision in a robotic swarm
Authors: Podpora Michal , Kawala-Sterniuk Aleksandra , Kovalchuk Viktoria , Bialic Grzegorz , Piekielny Pawel
Published: July 2020

Objectives

In this paper a novel approach regarding image analysis in Machine Vision applications was proposed.

Methods

The presented concept consists of two issues: (1) shifting some of the complex image processing and understanding algorithms from a mobile robot to distributed computer, and (2) designing the cognitive system (in a distributed computer) in such a way, that it would be common for numerous robots. The authors of this work focused on image processing, and they propose to accelerate vision understanding by using Cooperative Vision (CoV), i.e., to get video input from cooperating robots and process it in a centralized system.

Results

To verify the purposefulness of such approach, a comparative study is currently being conducted, involving a classical single-camera Computer Vision (CV) mobile robot and two (or more) single-camera CV robots cooperating in CoV mode.

Conclusions

The CoV system is being designed and implemented so that the algorithm would be able to utilize multiple video sources for recognition of objects on the very same scene.
Personal branding in an elevator: Developing job search pitch skills in tertiary level Business English pedagogy
Authors: Łącka-Badura Jolanta
Published: July 2020

This contribution reports on the use of genre-based instruction in developing students’ job search pitch skills in a Business English course taught at the tertiary level. The job search pitch (also referred to as personal branding pitch) is viewed as a subgenre of an elevator pitch; it is regarded as an essential communication tool to be mastered and used by students in future job search situations. Drawing on the available literature as well as the author’s own research and experience, the report demonstrates how the generic structure and rhetorical devices contributing to the realisation of the communicative function of job search pitch are incorporated in the job search module of an undergraduate Business English course taught at the University of Economics in Katowice. It also provides a brief account of students’ reflections and observations related to the usefulness of job search pitch skills and the challenges involved in their development.
The effect of the stress distribution of anchorage and stress in the textured layer on the durability of new anchorages
Authors: Tomaszewicz Dariusz , Jablonska-Krysiewicz Agnieszka , Szlendak Jerzy K.
Published: July 2020

The paper estimated the effect of the distribution of edge and shear stresses occurring in the façade texture layer of three-layer walls of large slab panel buildings, as well as the variability of these stresses depending on the anchorage strength of the anchorage. Bonded anchors with seven different diameters M8 ÷ M30, selected based on catalogues, were analysed. The traction stress was determined based on the destructive force, which is determined by the catalogues of manufacturers of bonded anchors. Depending on the choice of the method of repairing the connections between the textured layer and the structural layer, we give the three-layer walls a new character of work. One of the methods of strengthening the textured layer is the popular COPY-ECO system in Poland. It is a system of two anchors (horizontal and diagonal), reflecting the shape of the work of existing hangers. The article also analyses the variants of oblique anchorages for the M12 anchor with inclination angles of 30∘, 45∘ and 60∘. The extent to which the anchorage inclination angle has been assessed influences the higher parameters of the anchor’s bearing capacity due to the shearing of the textured layer.

Two-weighted inequalities for maximal operators related to Schrödinger differential operator
Authors: Vignatti Maria Amelia , Salinas Oscar , Hartzstein Silvia
Published: July 2020

We introduce classes of pairs of weights closely related to Schrödinger operators, which allow us to get two-weight boundedness results for the Schrödinger fractional integral and its commutators.
The techniques applied in the proofs strongly rely on one hand, boundedness results in the setting of finite measure spaces of homogeneous type and, on the other hand, Fefferman–Stein-type inequalities that connect maximal operators naturally associated to Schrödinger operators.
Homological epimorphisms, homotopy epimorphisms and acyclic maps
Authors: Chuang Joseph , Lazarev Andrey
Published: July 2020

We show that the notions of homotopy epimorphism and homological epimorphism in the category of differential graded algebras are equivalent.
As an application we obtain a characterization of acyclic maps of topological spaces in terms of induced maps of their chain algebras of based loop spaces. In the case of a universal acyclic map we obtain, for a wide class of spaces, an explicit algebraic description for these induced maps in terms of derived localization.

In order to identifying of high yielding compatible sunflower hybrids for different regions of Iran, a set of 10 exotic hybrids from Serbia, Turkey, and Italy and four Iranian hybrids were evaluated for agronomic traits; days to flowering and maturity, plant height, head and stem diameter, 1000-achenes weight, achene number per head, oil content and achene, and oil yield. The experiments were conducted as completely randomized block design with four replications in Alborz, Mazandaran, Khuzestan, and West Azerbaijan Provinces for two years (2017–2018). According to the results growing period of the hybrids were variable from 86 days for Dukat to 98 days for Fantaziya. The hybrids Slatki and Dukat had the highest (70 g) and lowest (56 g) 1000-achenes weight. The highest oil content was observed in 08TR003 (45.6%). Among the locations, Miandoab had the highest achene yield (3110 kg/ha). In Sari; the hybrids Barzegar, Fantaziya, and Slatki (3080, 2893, and 2853 kg/ha respectively), In Dezful; Barzegar, Cartago, and Oscar (3234, 3409, and 3226 kg/ha respectively), in Karaj; Oscar, Shams, and Fantaziya (3138, 3081, and 3050 kg/ha respectively), and in Miandob Shams, Fantaziya, and Slatki (4093, 4038, and 3895 kg/ha respectively) had the highest achene yield. Considering overall mean Fantaziya, Shams, and Oskar had the highest achene yield (3286, 3145, and 3087 kg/ha respectively), as well as Fantaziya followed by Barzegar and Shams had the highest oil yield (1396, 1335, and 1330 kg/ha respectively). Considering phenotypic variability among the exotic hybrids Fantaziya, Oskar, Slatki, Novak, 08TR003, and Meteor with lower coefficient of variation and higher achene yield considered as the stable higher yielding hybrids in four test locations of Iran.

Published: July 2020

Photo catalytic degradation of pollutants is one of the techniques used for treatment of dye contaminated wastewater. TiO2 has attracted much attention as photo catalyst for treatment of contaminated water. In this study, the photo catalytic performance of TiO2 has been enhanced by formation of p–n Co3O4-TiO2 hetero-junction. The p–n Co3O4-TiO2 hetero-junction was prepared by wet incipient impregnation method and characterized by various techniques. The photo catalytic activity of prepared composite was evaluated by photo degradation of methyl orange. The as prepared Co3O4-TiO2 composite was found as effective catalyst than Co3O4 and TiO2. The higher photo catalytic activity was attributed to p–n junction formed between Co3O4 and TiO2. The degradation data was analyzed according to Eley–Rideal mechanism in terms of 1st and 2nd order kinetics.
The Social Practice of Being Born Again: Historical and Cultural-Sociological Perspectives on Conversionist Piety
Authors: Krause Katharina
Published: July 2020

What kind of practices, emotions and self-understandings are linked to conversion? This contribution offers a set of analytical tools which help to understand processes of constructing, performing and maintaining conversionist identity. In doing so, it builds on both, source material related to 17th and 18th century New England and conversion research in the area of sociology, anthropology, and cultural studies. Holistic in its approach, it reconstructs conversionist piety as a social practice that builds up into pious cultures of body, emotion, and meaning-making. The analytical concepts developed on the way may prove to be a starting point for further empirical research on lived religion in Practical Theology and Religious Studies.
Religious Speech as Resource. A Research Report
Authors: Conrad Ruth , Hardenberg Roland
Published: July 2020

Religious speeches aim at social efficacy. They are therefore an important resource for religious communities and groups. The article pursues a cultural concept of resources, which does not ask about the benefit of a resource, but about its values in and effects on societies. The crucial elements are the social dynamics, actions and relationships that are closely related to culturally shaped interests in and use of resources. This concept is brought into conversation with more recent research on Christian and Islamic preaching cultures. Anthropological research in particular has repeatedly pointed to the social value attributed to preaching. This interdisciplinary article shows the yield of the dialogue between anthropology and practical theology.

Authors: Staszewski Cara L. , Garretto Diana , Garry Evan T. , Ly Victoria , Davis Jay A. , Herrera Kimberly M.
Published: July 2020

Objectives

To compare pregnancy outcomes with medication assisted treatment using. methadone or buprenorphine in term mothers with opioid use disorder.

Methods

A cohort of women receiving medication assisted treatment with either methadone or buprenorphine were identified from delivery records over a 10‐year period. Women were excluded with delivery <37 weeks, multiple gestations, or a known anomalous fetus. Maternal demographics, medications, mode of delivery, birthweight, newborn length of stay, and neonatal abstinence syndrome were extracted. The study was IRB approved and a p-value of <0.05 was significant.

Results

There were 260 women, 140 (53.8%) with methadone use and 120 (46.2%) with buprenorphine use. Groups were similar for maternal age, race, parity, homeless rate, tobacco use, mode of delivery and incidence of neonatal abstinence syndrome. The methadone group had a lower mean newborn birthweight (2874±459 g) and a greater incidence of low birth weight (11.4%) than the buprenorphine group (3282±452 g; p<0.001 and 2.5%; p=0.006). The incidence of neonatal abstinence syndrome was similar between groups (97% methadone vs. 92.5% buprenorphine; p=0.08). The methadone group had a longer newborn length of stay (11.4+7.4 days) and more newborn treatment with morphine (44.6%) than the buprenorphine group (8.2+4.4 days; p<0.001 and 24.2%; p<0.001). Maternal methadone use was an independent predictor for a newborn length of hospital stay >7 days (OR 3.61; 95% confidence interval 1.32–9.86; p=0.01).

Conclusions

Medication assisted treatment favors buprenorphine use when compared to. methadone with an increased birthweight, reduced need for newborn treatment, and a shorter newborn length of stay in term infants.

Published: July 2020

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2)–associated infection (COVID-19) is affecting populations worldwide. This statement may serve as guidance for infection prevention and safe ultrasound practices during the COVID-19 pandemic. Ultrasound examination is a fundamental part of obstetric care, yet it is a potential vector for transmission of SARS-CoV-2. Decontamination methods should always be implemented for ultrasound equipment, especially in the presence of suspected or confirmed COVID-19 cases. There must be workflow policies to protect pregnant women and healthcare providers from nosocomial cross transmission of SARS-CoV-2. Cleaning and disinfecting of equipment must be in accordance with their potential of pathogen transmission. Consider using telemedicine and genetic technologies as an adjunctive of obstetric ultrasound to reduce patient crowding. Patient triage and education of healthcare providers of infection prevention are crucial to minimize cross contamination of SARS-CoV-2 during obstetric ultrasound.

Total parenteral nutrition-induced Wernicke’s encephalopathy after oncologic gastrointestinal surgery
Authors: Fedeli Piergiorgio , Justin Davies Richard , Cirocchi Roberto , Popivanov Georgi , Bruzzone Paolo , Giustozzi Michela
Published: July 2020

Carl Wernicke described the disease bearing his name in 1881 and reported three cases characterized by the presence of mental confusion, ataxia, and ophthalmoplegia. Wernicke’s disease is mainly observed in alcoholic patients, due to decreased vitamin intake as a consequence of an unbalanced diet, and a reduction of absorption due to the effects of alcohol. Likewise, inadequate vitamin intake is prevalent in older patients. Wernicke’s encephalopathy due to inappropriate total parenteral nutrition (TPN) occurs infrequently; recently, there is an increase in the literature concerning Wernicke’s encephalopathy in patients after general and bariatric surgeries. We present two cases of Wernicke’s encephalopathy after oncologic gastrointestinal surgery by failure to administer vitamin B1 during TPN; to our knowledge, these are the first two cases of Wernicke’s encephalopathy after colorectal surgery for cancer. In our opinion, timely diagnosis and treatment are mandatory to avoid nonfunctional recovery and consequent malpractice legal actions as well as an increase in the health-care costs correlated with the prolonged hospital stay and with the nonfunctional recovery.
Near-field plates and the near zone of metasurfaces
Authors: Merlin Roberto
Published: July 2020

A brief, tutorial account is given of the differences between the near and far regions of the electromagnetic field emphasizing the source-dependent behavior of the former and the universal properties of the latter. Field patterns of near-field plates, that is, metasurfaces used for sub-wavelength applications, are discussed in some detail. Examples are given of fields that decay away from the plates in an exponential manner, a ubiquitous feature of many interface problems, and metasurfaces for which the decay is not exponential, but algebraic. It is also shown that a properly designed system of two parallel near-field plates can produce fields that exhibit pseudo minima, which are potentially useful for near-field tweezer-like applications.

Trans-border Friendships and Strategic Inclinations: Some Insights on the Molecular Emergence of Subversion in Chile
Authors: Donoso Patricio Azócar , Retamales Hugo Sir
Published: July 2020

In the last 30 years, Chile has crowned itself as one of the most singular, sophisticated, and cruel reference points of the global neoliberal laboratory. This article delves into the conceptual thinking of that laboratory by investigating the formation of an emotive-financial consensus based on the operation of institutionalizing sadism and a masochism of merit that profits from the affective destruction of collective intelligence. It situates this dystopic Chilean reality within the broader Latin American context, where the delicate administration of crisis and fear exposes the affective inclinations of persistence and resistance.
Brexit and the limits of Article 50 Treaty of the European Union
Authors: Barata Mario
Published: July 2020

This article aims to analyse the limits of Article 50 of the Treaty of the European Union (TEU) which expressly consecrates a Member State’s unilateral right to leave the Union. However, the provision seems to raise more questions than it answers due to the lack of concrete legal guidelines, and Brexit has underlined this reality. For example, the exit procedure contemplates the possibility of signing a withdrawal agreement with the European Union (EU), but it does not discipline its content. In our opinion, any agreement must regulate three questions: fundamental rights, financial settlement, and borders. A second limitation refers to the possibility of a Member State withdrawing its withdrawal notice. This question has recently been decided by the Court of Justice of the European Union (CJEU) in a manner that leaves the EU without any say in the process. Finally, the provision does not deal with the constitutional implications of withdrawal: treaty revision, institutional deadlock, and institutional representation. In sum, these critical omissions are analysed considering the relevant legal doctrine, jurisprudence, as well as the Brexit process. It also proposed that Article 50 of the TEU be amended in the future.
Brahmanical Patriarchy and Voices from Below: Ambedkar‘s Characterization of Women’s Emancipation
Authors: Senanayake Harsha , Trigunayat Samarth
Published: July 2020

Western feminism created a revolution on the international stage urging the world to look at things through the perspective of women who were historically suppressed because of their gender, yet in many instances, it failed to address the issue of women in the Indian subcontinent because of the existence of social hierarchies that are alien concepts to the western world. As a result, the impact of western feminist thinkers was limited to only the elites in the Indian subcontinent. The idea of social hierarchy is infamously unique to the South Asian context and hence, in the view of the authors, this evil has to be fought through homegrown approaches which have to address these double disadvantages that women suffer in this part of the world. While many have tried to characterize Ambedkar’s political and social philosophy into one of the ideological labels, his philosophy was essentially ‘a persistent attempt to think things through’. It becomes important here to understand what made Ambedkar different from others; what was his social condition and his status in a hierarchal Hindu Society. As a matter of his epistemology, his research and contribution did not merely stem from any particular compartmentalized consideration of politics or society, rather it encompassed the contemporary socio-political reality taking into consideration other intersectionalities like gender and caste. The paper argues for a system of convergence of casteism and sexism rather than an isolated approach to counter the gender inequalities. This convergence is important to be considered because most of the Indian feminist thinkers of our times are qualifying patriarchy with the term ‘Brahmanical’.
The role of exosome lipids in central nervous system diseases
Authors: Wang Ge , Wang Yong , Liu Ningyuan , Liu Mujun
Published: July 2020

Central nervous system (CNS) diseases are common diseases that threaten human health. The CNS is highly enriched in lipids, which play important roles in maintaining normal physiological functions of the nervous system. Moreover, many CNS diseases are closely associated with abnormal lipid metabolism. Exosomes are a subtype of extracellular vesicles (EVs) secreted from multivesicular bodies (MVBs) . Through novel forms of intercellular communication, exosomes secreted by brain cells can mediate inter-neuronal signaling and play important roles in the pathogenesis of CNS diseases. Lipids are essential components of exosomes, with cholesterol and sphingolipid as representative constituents of its bilayer membrane. In the CNS, lipids are closely related to the formation and function of exosomes. Their dysregulation causes abnormalities in exosomes, which may, in turn, lead to dysfunctions in inter-neuronal communication and promote diseases. Therefore, the role of lipids in the treatment of neurological diseases through exosomes has received increasing attention. The aim of this review is to discuss the relationship between lipids and exosomes and their roles in CNS diseases.
Authoritarianism, Prejudice, and Support for Welfare Chauvinism in the United States
Authors: Kehrberg Jason
Published: July 2020

This article examines the role of authoritarianism in shaping individual policy support for creating a waiting period before legal immigrants can access welfare programs. I use logistic regression models to analyse the opinions of non-Latino whites from the 1992 American National Election Study (ANES). I find that authoritarianism is related to a waiting period before immigrants can access welfare benefits, despite a significant number of non-authoritarians also preferring a waiting period. This effect is robust with the inclusion of several traditional predictors of welfare attitudes.
3D modelling for realistic training and learning
Authors: Bati Ayse Hilal
Published: July 2020

Objectives

Three-dimensional (3D) reconstruction and modelling techniques based on computer vision have shown significant progress in recent years. Patient-specific models, which are derived from the imaging data set and are anatomically consistent with each other, are important for the development of knowledge and skills. The purpose of this article is to share information about three-dimensional (3D) reconstruction and modelling techniques and its importance in medical education.

Methods

As 3D printing technology develops and costs are lower, adaptation to the original model will increase, thus making models suitable for the anatomical structure and texture. 3D printing has emerged as an innovative way to help surgeons implement more complex procedures.

Results

Recent studies have shown that 3D modelling is a powerful tool for pre-operative planning, proofing, and decision-making. 3D models have excellent potential for alternative interventions and surgical training on both normal and pathological anatomy. 3D printing is an attractive, powerful and versatile technology.

Conclusions

Patient-specific models can improve performance and improve learning faster, while improving the knowledge, management and confidence of trainees, whatever their area of expertise. Physical interaction with models has proven to be the key to gaining the necessary motor skills for surgical intervention.
Comparison of different equations for estimation of low-density lipoprotein (LDL) – cholesterol
Authors: Alpdemir Mehmet Fatih , Alpdemir Medine
Published: July 2020

Objectives

The aim of this study was to compare low-density lipoprotein cholesterol (LDL-C) estimations using various formulas with directly measured LDL-C (d-LDL-C) in the Turkish population.

Material and methods

A total of 1,478 participants who were aged between 18 and 80 were classified into five groups according to serum triglyseride (TG) concentration as follows: <100, 100–199, 200–299, 300–399, and 400–1000 mg/dL. Glucose (Glu), LDL-C, total cholesterol (TC), HDL-C, TG, and HbA1C were measured with Cobas 6000 c501. d-LDL-C concentrations were measured by a homogenous direct assay using reagents. We investigated the accuracy 10 equations that are Friedewald, De Cordova, Ahmadi, Anandaraja, Teerakanchana, Chen, Hattori, Vujovic, Puavillai, and Hatta for estimating LDL-C in this study.

Results

In group 1, Anandaraja formula correlated best with d-LDL-C (r=0.367), but this correlation is weakly. In group 2; Teerakanchana formula (r=0.931), in group 3; Friedewald and Teerakanchana formulas (r=0.935, r=0.961), in group 4; Teerakanchana formula (r=0.950) and in group 5, Anandaraja formula (r=0.792) correlated best with d-LDL-C.

Conclusions

In this study, although there was a strong correlation between d-LDL-C measurement and estimated LDL-C formulas, there was a negative bias between results of these formulas and the d- LDL-C.
The effect of diurnal variation on erythrocyte sedimentation rate
Authors: Yucel Muammer , Ihtiyar Alperen , Koseoglu Mehmet
Published: July 2020

Objectives

It has been known that some laboratory tests showed diurnal variation and were affected by fasting-satiety status. We aimed to examine erythrocyte sedimentation rate (ESR) for both pre-analytical factors.

Methods

Blood samples from 12 volunteers were taken and studied with the Westergren method. Fasting blood samples taken at 9:00 am were accepted as basal. Samples were taken at 10:00, 11:00, 12:00 were compared with baseline to evaluate fasting-satiety status and samples taken at 12:00, 15:00, 18:00, and 24:00 to evaluate diurnal variation.

Results

ESR was found to be the lowest at 09:00 and 15:00 (Median=5.5 mm/h). The 10:00, 11:00, and 12:00 results for assessing fasting-satiety status on ESR were not different than the baseline (6.2, 6.0, and 7.8 mm/h, respectively). The rates at 18:00 and 24:00 were not found to be different than the baseline (5.7 and 6.6 mm/h).

Conclusions

We didn’t find that ESR had diurnal variation, and it wasn’t affected by fasting-satiety status. Although it is known that routine biochemistry tests should be performed from the blood sample taken in the morning in case of starvation, blood sampling can be done for ESR during the day if necessary.

Published: July 2020

Small copper-oxide cluster cations, namely, CuOAr+ and Cu2O2
+, are studied by mass spectrometry and X-ray absorption spectroscopy (XAS) to investigate the oxidation state of copper atoms. The XAS in Cu L3-region revealed that the oxidation number of Cu is almost +2.1 and +2.3 for CuOAr+ and Cu2O2
+, respectively, which are consistent with the natural charges obtained by quantum chemical calculation. It was also revealed that the binding energy of Ar to CuO+ is unexpectedly high to form CuOAr+ dominantly as a result of a significant amount of charge transfer to the Ar atom.
Comparative Study on Bearing Capacity of Bottom Ash–Stabilized Soil Mixed with Natural and Synthetic Fibers
Authors: Prasannan Swetha , Kolathayar Sreevalsa , Sharma Anil Kumar
Published: July 2020

This article assesses the strength behavior of bottom ash (BA)–stabilized soil mixed with different fibers through a series of laboratory tests. Optimum BA and fiber percentage were obtained by small scale lab tests like compaction tests and unconfined compressive strength (UCS) tests. From compaction tests with varying proportions of BA (10, 20, 30, and 40 %), the optimum BA content was found to be 30 %. With this optimum BA content, UCS tests were conducted on soil-BA mix with different fibers (coir, areca, sisal, and polyvinyl alcohol) at various percentages (0.5, 1, 1.5, and 2 %) to find the optimum fiber content. A set of model footing tests were done to check the credibility of using fibers as a strengthening material beneath footing to upgrade the engineering properties of soil to make a reasonable subsoil for the foundation. A total of six model footing tests were performed on raw soil, on soil with optimum BA content, and on BA–stabilized soil mixed with different fibers in their optimum percentage (1.5 %). The bearing capacity of unstabilized unreinforced soil was found to increase significantly with the inclusion of fibers.

Vibrações em estruturas geralmente são efeitos indesejados e que podem causar atéo colapso total. Esses fenômenos ocorrem em estruturas de grande porte submetidasà excitações dinâmicas periódicas, como é o caso da ação das ondas em plataformasde petróleo ou da ação dos ventos em pontes. Tendo em vista a utilização crescentede perfis de alma corrugada nessas estruturas onde os esforços de flexão predominamsobre os demais esforços, faz-se necessário avaliar o comportamento de vigas comalmas corrugadas mediante solicitações dinâmicas. Nesse contexto, desenvolve-se umestudo com o intuito de comparar as frequências naturais e os modos de vibração deperfis com uma e duas almas corrugadas senoidais avaliando diferentes configuraçõesgeométricas e seus possíveis ganhos de rigidez. Por fim, conclui-se que perfis com duasalmas senoidais podem apresentar ganhos de rigidez variando-se apenas a distânciaentre as almas.
