Treating skin conditions: a holistic approach in dermatology
Authors: Coleman Emma
Published: March 2020

This article is a review of current evidence to both support and refute holistic approaches to dermatological cases, including analysis of data linked to psychodermatology, psychosocial and lifestyle influences.

A case for taking an integrated approach adjuvant to traditional medicine in skin disease therapy, how this could save time, money and reduce pressure on resources will be discussed. Overall, the research is promising; however, there are gaps in knowledge and there is a need for long-term, larger scale studies in the future. Also, an improved understanding of the processes that lead to inflammatory cutaneous diseases in the future will enable practitioners to make better treatment choices.

How to Burn a Network or Spread Alarm
Authors: Simon Marek , Huraj Ladislav , Dirgova Luptakova Iveta , Pospichal Jiri
Published: March 2020

This paper compares centrality indices usage within a heuristic method for a fast spread of alarm, or crucial information. Such indices can be used as a core part within more sophisticated optimisation methods, which should determine a graph parameter - burning number, defining, how fast can an alarm spread through all nodes. In this procedure at each time step a new chosen node is alarmed (i.e. burned) “from outside”, and already alarmed nodes at each time step then alarm their neighbours. The procedure ends, when all the nodes are alarmed (i.e. burned). The optimisation heuristic should choose such ordered sequence of nodes, which are to be alarmed “from outside”, that their number, equal the number of time steps (i.e. burning number) necessary to alarm the whole network, is minimised. The NP completeness of the problem necessitates a usage of heuristics. However, even the heuristics can be slower, reaching towards a global optimum, or faster, exchanging part of the quality for a time. This paper studies the usage of centrality indices in a simpler and faster heuristic. It should be useful e.g. for a mobile network of cars or drones, when an optimal solution cannot be computed in advance, or take too much CPU time, since the connections within the dynamic network might not exist any longer. A wide range of centrality indices was tested on selected networks, both real as well as artificially generated. While the performances of indices substantially differ for different types of networks, results show, which centrality indices work well across all tested networks.
Rectangular illumination method using LED arrays for machine vision
Authors: Zhang Huai-liang , Peng Ling , Luo Yong-kang , Yu Sheng
Published: March 2020

Machine vision image quality is significantly affected by illumination. Uniform illumination of a rectangular target surface requires a function for evaluating the illumination system. In this study, based on an LED array light source illuminance model, such an evaluation function was established. Further, the influence of the light source’s structure on illumination was analyzed using a single-factor analysis method to determine the boundary conditions, and it was then solved using a genetic algorithm to finalize the structural design. An experimental platform was built to measure the illuminance uniformity. The experimental results were consistent with the numerical results, verifying the effectiveness and feasibility of the proposed illumination method. Thus, this research provides a theoretical reference for the illumination of a rectangular target surface for vision-based detection.
Enhancement mechanism of the saturable absorption effect in reduced graphene oxide decorated with silver nanoparticles
Authors: Li Ming , Yan Lihe , Si Jinhai , Li Xiaoyu , Li Jianlin , Hou Xun
Published: March 2020

Reduced graphene oxide (rGO) decorated with silver nanoparticles exhibits an enhanced nonlinear absorption effect compared with pure rGO. Using femtosecond time-resolved transient absorption spectroscopy, the enhancement mechanism and carrier dynamics of the composites are experimentally demonstrated. When the material is excited by laser pulses, the excited carriers in the conduction band of graphene will transfer to the d-band of silver before returning to the valence band. As the decay process (∼210 ps) is much longer than that of the relaxation time in pure graphene (∼fs), the bleaching effect of valence band is prolonged, resulting in enhanced saturable absorption effect.
Hybrid integration methods for on-chip quantum photonics
Authors: Kim Je-Hyung , Aghaeimeibodi Shahriar , Carolan Jacques , Englund Dirk , Waks Edo
Published: March 2020

The goal of integrated quantum photonics is to combine components for
the generation, manipulation, and detection of nonclassical light in a
phase-stable and efficient platform. Solid-state quantum emitters have
recently reached outstanding performance as single-photon sources. In
parallel, photonic integrated circuits have been advanced to the point
that thousands of components can be controlled on a chip with high
efficiency and phase stability. Consequently, researchers are now
beginning to combine these leading quantum emitters and photonic
integrated circuit platforms to realize the best properties of each
technology. In this paper, we review recent advances in integrated
quantum photonics based on such hybrid systems. Although hybrid
integration solves many limitations of individual platforms, it also
introduces new challenges that arise from interfacing different
materials. We review various issues in solid-state quantum emitters
and photonic integrated circuits, the hybrid integration techniques
that bridge these two systems, and methods for chip-based manipulation
of photons and emitters. Finally, we discuss the remaining challenges
and future prospects of on-chip quantum photonics with integrated
quantum emitters.

When an intense, few-cycle light pulse impinges on a dielectric or semiconductor material, the electric field will interact nonlinearly with the solid, driving a coherent current. An asymmetry of the ultrashort, carrier-envelope-phase-stable waveform results in a net transfer of charge, which can be measured by macroscopic electric contact leads. This effect has been pioneered with extremely short, single-cycle laser pulses at low repetition rate, thus limiting the applicability of its potential for ultrafast electronics. We investigate lightwave-driven currents in gallium nitride using few-cycle laser pulses of nearly twice the duration and at a repetition rate 2 orders of magnitude higher than in previous work. We successfully simulate our experimental data with a theoretical model based on interfering multiphoton transitions, using the exact laser pulse shape retrieved from dispersion-scan measurements. Substantially increasing the repetition rate and relaxing the constraint on the pulse duration marks an important step forward toward applications of controlling currents with light.
Optical transmission matrix measurement sampled on a dense hexagonal lattice
Authors: Pai Pritam , Bosch Jeroen , Mosk Allard P.
Published: March 2020

The optical transmission matrix (TM) characterizes the transmission properties of a sample. We show a novel experimental procedure for measuring the TM of light waves in a slab geometry based on sampling the light field on a hexagonal lattice at the Rayleigh criterion. Our method enables the efficient measurement of a large fraction of the complete TM without oversampling while minimizing sampling crosstalk and the associated distortion of the statistics of the matrix elements. The procedure and analysis described here is demonstrated on a clear sample, which serves as an important reference for other systems and geometries, such as dense scattering media.

Published: March 2020

This work demonstrates a new photosensitive glassy material in the form of poly-di-methyl-siloxane (PDMS) loaded with novel Ge-derivatives. A femtosecond laser is used to write directly into the bulk of pristine and Ge-modified PDMS. Raman spectroscopy is used to study the origin of the stable refractive index (RI) change induced by fs laser exposure. Multimode waveguides, as well as a highly tunable diffraction gratings, were written into the bulk of the new material, Ge-PDMS, in order to demonstrate the inclusion of photonics structures embedded inside. Novel photonics functionality may now be incorporated into PDMS, which is a material widely used in the optics industry and for lab-on-chip application (LOC).
Talk for collaborative learning in computer-based music production
Authors: Dobson Elizabeth
Published: March 2020

This article presents a case study exploring the interrelationship between talk and learning in collaborative computer-based music production. Framed by Neil Mercer and Karen Littleton’s Sociocultural perspective on collaborative learning, research on talk and ‘thinking together’ for learning, this study observed two undergraduate composers as they co-produced a contemporary dance film soundtrack across one academic term. The composers recorded their collaboration, providing data for a systematic moment-by-moment micro-analysis focusing on the audio-visual aspects of this project over twelve weeks. Sociocultural discourse analysis methods were used to explore how social, cultural and concrete situations shaped the students’ developing common knowledge. Interaction analysis has been used to code turn functions and display talk characteristics and patterns. This research found that collaborative computer music production is a ‘cumulative conversation’, comprised of many ‘thinking spaces’ that foster ‘post-dialogic’ activity’ and ‘connection building’. In this case the students developed new ‘tools for progressive discourse’ providing them access to the remote and private ‘thinking spaces’ that are characteristic of longer-term co-creating. This research argues for the development of new pedagogies that focus on understanding how talk shapes collaborative learning within music technology.
‘Who is really gonna benefit?’: The punk habitus in the downtown Edmonton field
Authors: Kafara Rylan
Published: March 2020

The new home of the National Hockey League’s (NHL) Edmonton Oilers opened in 2016. This publicly financed, CAD 613.7 million arena was built in downtown Edmonton, Alberta. The arena and its broader entertainment district were designed to ‘revitalize’ Edmonton’s inner city that was already home to the majority of the city’s homeless population. The spatial transformation of Edmonton’s inner city was an example of what geographer Neil Smith referred to as ‘The New Urban Frontier’. Using Pierre Bourdieu’s theory of practice, this article explores how the local music community reacted to downtown gentrification through songs by punk bands Latcho Drom, Rebuild/Repair and Audio/Rocketry, along with rapper Cadence Weapon. This article assesses a series of reactions ranging from supportive and promotional to critical and resistive. By showing how musicians engaged in the debate over development, this article creates a template for assessing processes of gentrification, through the relationship between professional sport, media and music. It analyses the role of cultural production in the continued process of gentrification, future developments in cities and who belongs in the new urban landscape. In doing so, this article suggests the embodiment of a punk habitus by agents negotiating various fields in Edmonton and beyond.
I want something new: Limp Records and the birth of DC punk, 1976–80
Authors: Davis John R.
Published: March 2020

Recountings of the Washington, DC punk rock scene’s history often start with the founding of Dischord Records in 1980 and focus on the subsequent ascent of Dischord co-owner Ian MacKaye’s bands like Minor Threat and Fugazi. As seminal as Dischord remains in the narrative of DC punk – a community still thriving today – the years just prior to the label’s founding generated the scene’s true incunabula. Beginning with the self-released debut EP from the Slickee Boys in 1976, this first wave of DC bands – also including Razz, Nurses, White Boy and others – combined elements of art rock, surf, proto-punk, pub rock and power pop together to craft a protean version of punk that embraced eccentricity and humour, serving as the city’s own defiant rebuke of the staid state of 1970s rock music. No record label was more central to the nascent punk scene in DC than Limp Records. Operated by Skip Groff, Limp provided the punk community with its first proper record label. Rather than a label that centred around the efforts of a single band – as most other new DC punk labels did – Limp issued singles for several groups, collaborating with the fledgling Dacoit and O’Rourke labels to co-release defining singles for the Slickee Boys and Razz. DC punk would not have taken shape the way it did without Groff’s efforts, particularly considering his connections with bands like Bad Brains and the Slickee Boys and his musical and entrepreneurial influence on local teenage punks like MacKaye, Jeff Nelson and Henry Rollins. This article is a history of DC punk record labels from 1976 to 1980 and seeks to establish this overshadowed era of the scene as one of the most critical in the community’s 43-year existence. Considering the outsize influence the DC scene ultimately had on punk culture – whether through the eponymous clean living philosophy inspired by the Minor Threat song ‘Straight Edge’, the unwaveringly independent business model of Dischord or the pacesetting music reliably turned out each decade by participants in the scene – the impact of Groff and his first wave DC punk peers must be acknowledged.
Embodying history: Casting and cultural memory in 1776 and Hamilton
Authors: Harbert Elissa
Published: March 2020

Both Lin-Manuel Miranda’s Hamilton and recent all-female productions of Sherman Edwards and Peter Stone’s 1776 dramatize historical events of the American Revolution with women and people of colour in the roles of white ‘founding fathers’. This article juxtaposes the casting and reception of these history musicals to theorize the ways their non-traditional casting opens up new possibilities for cultural memory of that revered era in US history. Underlying the seemingly progressive embodied performance, the written texts of both 1776 and Hamilton perpetuate founders chic and rehearse traditional versions of the nation’s founding story. Thus they expose but do not subvert the construction of whiteness and masculinity as unmarked categories that have always dominated US culture. The process of upholding the old version while blending it with the new exemplifies the incremental process of cultural memory as it shapes national identity.
‘Don’t feed the plants!’: Monstrous normativity and disidentification in Little Shop of Horrors
Authors: Mandracchia Christen
Published: March 2020

The 1982 camp horror musical Little Shop of Horrors tells the story of a meek little flower shop attendant named Seymour, who comes across a novelty carnivorous plant that eats human blood. The talking plant preys on Seymour’s infatuation with his beautiful co-worker Audrey to radicalize him into feeding the plant ‘fresh’ bodies. Building on the work of theatre scholar Michael Chemers, who asserts that stage monsters represent larger social and political anxieties of their time, this article identifies Seymour, the normal, white, heterosexual everyman, as the real ‘monster’ of the musical. Thus, the musical’s creators, Alan Menken and Howard Ashman, exposed the monstrousness of normativity at the poignant moment in American culture, during the early years of the conservative Reagan administration. This article uses José Muñoz’s theory of ‘disidentification’, a strategy employed by marginalized people working ‘on and against dominant ideology’ to analyse the creators’ didactic and subversive strategy.
Kaspar Holten’s production of Szymanowski’s King Roger: A test of ‘fidelity’
Authors: Ewans Michael
Published: March 2020

Kaspar Holten’s production of Szymanowski’s King Roger (completed in 1924) is an important realization of this complex and challenging opera. It was premiered at the Royal Opera House, Covent Garden in 2015; a DVD recording of the London performances makes a detailed study of the production possible. This article is concerned with the issue of what constitutes fidelity in a director’s approach. It begins by discussing Szymanowski’s mise en scène, and outlines the main themes of King Roger and its relationship to Euripides’ Bacchae; then it engages with Holten’s interpretation, and the fascinating designs by Steffen Aarfing, which enable his vision to be realized. The lead characters – Roger and his Queen, Roxana – are both discussed with reference to how Holten illuminates Szymanowski’s drama and its music. His production raises fundamental questions about fidelity and innovation which have dominated critical discussion of many modernist and post-modernist productions not just of opera, but of ‘classics’ of the spoken theatre as well; these questions are posed in particular by Holten’s decision that Roxana should remain with Roger until the end of the opera, in violation of Szymanowski’s scenario.

MENGENAL MAKROALGA Turbinaria DAN PEMANFAATANNYA
Authors: Handayani Tri
Published: March 2020

KNOWING MACROALGAE Turbinaria AND THEIR USAGES. Turbinaria is a member of brown macroalgae that can be found in almost all Indonesian waters. Turbinaria is often regarded as Sargassum because they have a similar morphology and both belong to the Family Sargassaceae. There are 35 species of Turbinaria in the world and 11 of which can be found in Indonesia. Turbinaria conoides, T. decurrens and T. ornata are the most common ones in Indonesian waters. Turbinaria grows on rocky intertidal coastlines, tidepools and reef flats. The life cycle of Turbinaria occurs through alternations between sexual and asexual. Their biphasic life cycle contains gametophytes and sprorophytes. In their sexual reproduction, sporophytes resulted from the germination of zygotes formed by fusion (fertilization) of male and female gametes. Asexual spores develop from both sporophytes and gametophytes. Turbinaria was commonly used as a source of alginate, fucoidan and other bioactive polysaccharides (antioxidant, anticancer, antibacterial, anticoagulant, antiploriferative and antivirus activities).

Granulation Red Index To Assess Pressure Ulcer Granulation Tissue Quality Treated By Honey Gauze Dressing By Digital Image Analysis
Authors: Fortuna Fory , Putri Nandita Melati , Sudjatmiko Gentur
Published: March 2020

Background : Good formation of granulation tissue in the ulcer bed is regarded as one of the indicators of pressure ulcer healing. Granulation red index (GRI) had been published as an objective parameter to assess the quality of granulation tissue. Honey stimulates granulation of tissue and creates a moist healing environment. However, the assessment of granulation tissue quality of pressure ulcers treated by honey has yet to be proven in clinical settings. In this study, we evaluate the granulation tissue quality of pressure ulcers treated by honey using granulation red index by digital image analyses.
Method: There were 12 subjects who fulfill inclusion criteria treated by honey gauze dressing and were evaluated every week for three times measurements of %GRI and DESIGN-­‐score. Parameters of this study were the delta %GRI80 and DESIGN-­‐R score. Correlations were evaluated by Spearman’s correlation coefficient.
Result : The correlation  of  delta  GRI80%  and  DESIGN-­‐R  score  was  statistically  significant  from  baseline measurement to first week of treatment and to second week of treatment (r1=0.65, p1=0.02 and r3=0.832, p2=0.001). The correlation of delta GRI80% and DESIGN-­‐R score from first to second week therapy was not statistically significant (r=0.23, p=0.47), but the GRI80% from first week therapy to second week of therapy was increasing and DESIGN R score was decreasing.
Conclusion:This study shows the correlation of %GRI80 and DESIGN-­‐R score of pressure ulcer after the treatment of honey gauze dressing. This study hopefully assists further study for wound bed preparation assessment and treatment of pressure ulcer for surgical intervention.

Plastic surgery in Indonesia was pioneered and developed by Moenadjat Wiratmadja, MD., in 1958. This specialty experienced many developments and improvements over time with more specific subspecialties to facilitate the advancement of the science of plastic surgery, including the reconstructive microsurgery subspecialty. The reconstructive microsurgery service in the plastic surgery division dr. Ciptomangunkusumo National Hospital (RSCM), Jakarta, Indonesia was first initiated by Sidik Setiamiharja, MD., self-taught from the textbooks. In late 1985, following the success of conducting the first basic microsurgery course in Jakarta, the plastic surgery team in RSCM which consisted of Sidik Setiamihardja, MD, Chaula L. Sukasah, MD and Gentur Sudjatmiko, M.D. pioneered many of the first microsurgery cases, including the first major limb replantation, first penile replantation and the first free flap. Overtime, the reconstructive microsurgery subspecialty has been growing significantly. In 2019, the number of free flap cases at RSCM reached the highest number in Indonesia with 90 free flap cases with 94% success rate.

Die Buchpublikationen der „Academic Communities“ in Dänemark und den Niederlanden: Rückschlüsse für globale Publikationsstrategien
Authors: Tausch Arno
Published: March 2020

Unser Aufsatz hat zahlreiche Kriterien entwickelt, mit denen die Bibliometrie und Szientometrie des auf akademische Bücher spezialisierten Verlagswesens betrieben werden kann. Wir testen den Einfluss von Messgrößen, wie sie auf Grund von Altmetrics, Entlehnungsstatistiken, Libcitation nach OCLC Worldcat und anderen Unionskatalogen in Industrie- und Entwicklungsländern, subjektivem Ranking durch academic communities und Zitierungen im Book Citation Index gewonnen werden können. 57 global operierende Buchverlage, über die sämtliche Daten vorhanden sind, stehen dabei im Mittelpunkt. All diese Daten haben eine Relevanz für die Publikationsstrategie-Beratung der Wissenschaft durch die Bibliotheksdienste im 21. Jahrhundert. Die Innovation dieses Aufsatzes besteht vor allem in der Verwendung von neuen Daten über die Publikationspräferenz zweier renommierter akademischer communities in Europa, nämlich Dänemark (landesweit) und von der Reichsuniversität Groningen in den Niederlanden in der multivariaten Analyse. Unsere Auswertungen zeigen, dass sowohl Ansätze, die auf die Zitierungen im Book Citation Index oder auf Größen der Libcitation (globale Verbreitung im OCLC Worldcat) ausschließlichen Wert legen, die komplexe Realität des heutigen internationalen Publikationswesens nicht erfassen. Anders als Prototheorien des globalen Publikationswesens bisher annahmen, haben die Daten des Book Citation Index oder Libcitation (globale Verbreitung im OCLC Worldcat) keine besondere Bedeutung für die Publikationsentscheidungen der dänischen und niederländischen Wissenschaftler. Bei den dänischen Wissenschaftlern scheint der Faktor „size and high quality“ der ausschlaggebende zu sein. Für Groningen kommt als determinierender Faktor noch die international anerkannte Verlagsqualität hinzu. Vergleiche unserer Ergebnisse mit den landesweiten subjektiven Verlagseinschätzungen der einzigen Wissenschaftscommunity, wo solche Daten erhoben wurden (Spanien) bestätigen unsere multivariaten Ergebnisse.
Curve and surface construction based on the generalized toric-Bernstein basis functions
Authors: Li Jing-Gai , Zhu Chun-Gang
Published: March 2020

The construction of parametric curve and surface plays an important role in computer aided geometric design (CAGD), computer aided design (CAD), and geometric modeling. In this paper, we define a new kind of blending functions associated with a real points set, called generalized toric-Bernstein (GT-Bernstein) basis functions. Then, the generalized toric-Bézier (GT-Bézier) curves and surfaces are constructed based on the GT-Bernstein basis functions, which are the projections of the (irrational) toric varieties in fact and the generalizations of the classical rational Bézier curves/surfaces and toric surface patches. Furthermore, we also study the properties of the presented curves and surfaces, including the limiting properties of weights and knots. Some representative examples verify the properties and results.
Where is the Great Outdoors of Meillassoux’s Speculative Materialism?
Authors: Šatkauskas Ignas
Published: March 2020

Quentin Meillassoux’s speculative materialism aims to define access to reality of the natural world apart from its giveness to sentient subjects. This world apart is designated by Meillassoux as the “Great Outdoors” which was marginalized as a topic of philosophy after Kant’s critiques. The question of the incommensurability of human subjects and physical objects is taken up by Meillassoux and addressed by allowing mathematizable properties of physical objects to be referred to objectively in mathematical statements. In this paper we follow the discussion with speculative materialism conducted by Deborah Danowski and Eduardo Viveiros de Castro in The Ends of the World (2017). These authors show that Meillassoux’s conception of the “Great Outdoors” includes, yet insufficiently explores, the notion of ancestral humanity in Amerindian myth – and intimately related to the practice of hallucinogenic trance – as the means to address the problem of said incommensurability.

PROJECT MANAGER JOB DESCRIPTION AS ONE OF PROJECT MANAGEMENTKEY SUCCESS FACTORS
Authors: Kolesnikov Oleksii E. , Lukianov Dmytro V. , Sherstyuk Olha I. , Kolesnikova Kateryna V.
Published: March 2020

The article discusses the practical aspects of profiling knowledge in project management, taking into account competence and experience for various categories of professionals involved in project management. Very often, project managers are forced to not only manage the project, but also train the project team members or help them develop their best skills to achieve the project goal. It is shown that success of project activities of organizations substantially depends on the professional personnel training and the proper formation of project participants' job descriptions. In addition to the formal responsibilities outlined in the basic project management methodologies the project manager plays an important role in the interaction between the project and the business area.Market pressure on project activities is associated with a rapid reduction in the life cycles of technologies and products, which significantly increases the responsibility of project managers for the ultimate fate of their project outputs. The employees’ knowledge, skills and competencies are the basis for the development and improvement of any organization. In this case, more and more situations arise when, under extremely short deadlines, it is necessary to make a decision on the project team formation and on the selection of the project manager. When executing projects, there is always a need to coordinate the work of managers, staff and project team. To do this, organizations develop the rules of interaction and managers’ responsibilities, as well as determine the managers’ responsibility for various types of work. The responsibilities of managers are fixed in the job descriptions, which serve as the basis for the formation of responsibility matrices. At the same time, the fulfillment of the type of work specified in the instruction must be supported by the performer’s certain competence. A general concept of forming job descriptions is proposed. Each instruction point is formed at the intersection of three coordinates: the performer, the work and the competence. A Markov model for changing the project manager’s states has been developed, which describes the system using homogeneous Markov chains with discrete states and time. Discrete states form a specific structure of communications and interaction of project processes, which take into account the system topology and contextual features of the processes of project activities.

Operational features of modern distributed information systems significantly increase the requirements for the reliability oftheir functioning and tighten the time limits for its restoration. High reliability of work is provided by various tools, in particular, offline and online testing, but often limiting the real time of the operation of these systems. Well-known testing methods use hardware accelerators, decomposition and parallelization, artificial intelligence technologies, but their capabilities do not remove the advisability of developing new models and methods, in particular, high-level ones, based on a special analysis of system behavior. The article presents a multi-level method of online behavioral testing of distributed information systems, based on hierarchical Petri nets, single-level model and method, and alsohierarchicalmodel of online behavioral testing. The multi-level method uses evolutionary optimization and has the features of parallel multi-level organization of compatible check evolutions of individual levels, which develop according to the principle of a “wave” algorithm in the background relative to the mainfunctioning of the distributed information systems themselves. To determine the complex testingcriteria in the check evolutions of the multilevel method, a hierarchical system of compatible functions of fitness and the choice of objects in the level evolutions of the hierarchical model is proposed. The functions offer completeness estimates for positions, transitions and arcs of Petri nets, linear and nonlinear graph behavior structures, theaction of functions is extended to check primitives and fragments. The hierarchy of fitness and choice functions made it possible to introduce estimationsof completeness of testing used to optimize evolutionary search in a multi-level coverage of necessary checks. Hierarchical decomposition, evolutionary approach and hierarchy of optimizing fitness and choice functions of a multi-level method made it possible to reduce time and increase the flexibility of organizing online behavioral testing, taking into account the features of distributed information systems.

The article is devoted to the development of a method for determining the minimum interaction surface in a system of heat exchangers. A comparative analysis of direct-flow and counter-current types of heat exchange is carried out in relation to the creation of systems for ensuring temperature conditions, for which weight and size characteristics are decisive. It is shown that the main characteristic of efficiency in the design and simulation of heat exchangers, based on the temperature representation, is not applicable for devices with a phase transition.The definition of efficiency as the energy characteristic of the energy exchange process of interacting flows is proposed. Comparison of the energy received by the heated stream from the heating stream made it possible to determine the energy potential in the heat exchanger. The introduction of energy efficiency made it possible to substantiate the relationship between the efficiency of once-through and counter-flow heat exchangers with access to structural and thermophysical requirements. The analysis of analytical relationships showed that in assessing the thermal stresses arising in the apparatus, the determination of average values over the surface of the temperature of the coolant plays a significant role.It is shown that the countercurrent heat exchanger represents the limiting case of minimizing the heat transfer area. The increase in the efficiency of once-through heat exchangers due to sectioning is analyzed and the possibility of increasing the efficiency of once-through heat exchangers is shown. The research results indicate not only the topological equivalence of the direct-flow apparatus system to one counter-current, but also the possibility of constructing a partitioned apparatus system with the serial connection of its elements with an efficiency equal to the efficiency of counter-current apparatuses.A recursive algorithm is proposed for constructing a partitioned system of direct-flow apparatus. The developed method can be used to create computer-aided design systems for heat exchangers of complex chemical plants.
Acute Respiratory Distress Syndrome in Preterm Newborns (Morphological Study)
Authors: Perepelitsa S. A.
Published: March 2020

The aim of the study is to provide a rationale for the morphological diagnostic criteria of respiratory distress syndrome (RDS) and acute respiratory distress syndrome of the newborn (ARDSN) in extremely preterm newborn infants.

Materials and methods. Autopsy protocols of 31 newborns were studied. The average gestational age of children was 28.9±5.3 weeks, body weight at birth was 1404±945 grams. Fifty eight percent of newborns in the sample had extremely low body weight (ELBW). At birth, all newborns were found to have severe asphyxia, and the median score on the Apgar scale at the 1st minute of life was 3 [2; 5] points. In all cases there was an unfavorable course of the disease. The median life span was 72 [22; 181] hours.

The results of the study. The study revealed two variants of hyaline membrane formation in preterm newborns with acute respiratory failure. Hyaline membranes in the lungs were found in 93.5% of newborns, in 51.6% of cases there was ARDSN due to the primary surfactant deﬁciency, in 41.9% of children ARDS was due to immature lung being exposed to various direct and indirect damaging factors. In all cases a distinct morphological pattern in newborns with the hyaline membranes was identiﬁed: immaturity and antenatal damage to air-blood barrier, pneumonia, microaspiration, ischemia of the lungs.

Conclusion. Acute respiratory distress syndrome is typical for 41.9% of extremely preterm infants, its development is favored by exposure of immature lungs to direct (congenital pneumonia, amniotic ﬂuid aspiration) and indirect (severe perinatal hypoxia with ischemia, shock, hemorrhagic syndrome) damaging factors. Morphological signs of ARDS were most often found in newborns with congenital pneumonia, asphyxia, neonatal aspiration of amniotic ﬂuid.

ANALISIS KEMAMPUAN BERPIKIR KRITIS SISWA DALAM MENYELESAIKAN SOAL LITERASI SAINS BERDASARKAN TINGKAT KEMAMPUAN METAKOGNISIAbstractThe purpose of this study is to describe students critical tninking skill in solving scientific literacy based on metacognition ability. This research is descriptive research. The subject of this research is 99 students of grade XI in SMA Batik 2 Surakarta. Data collection methods used are test methods and questionnaires. Data analysis techniques use quantitative descriptive analysis. The results showed that the achievement of scientific literacy in science as a body of knowledge, science as a way of thinking, science a way of investigating, science as interaction between technology and society less than 50%. This is because the students' critical thinking skill in the assessment, inference and strategy in solving scientific literacy problem is still low that is below 20%. The low ability of critical thinking due to the students' metacognition level is still low, 84% of students are at the metacognition ability level on tacit use and awareness use and 16% of students on the strategic use level and no students on reflective use level.AbstrakPenelitian ini bertujuan untuk mendeskripsikan kemampuan berpikir kritis siswa dalam menyelesaikan soal literasi sains berdasarkan tingkat kemampuan metakognisi. Penelitian ini termasuk penelitian deskriptif. Subjek penelitian ini adalah 99 siswa kelas XI SMA Batik 2 Surakarta. Metode pengumpulan data yang digunakan adalah metode tes dan angket. Teknik analisis data mengunakan analisis deskriptif kuantitatif. Hasil penelitian menunjukkan bahwa ketercapaian literasi sains pada kategori science as a body of knowledge, science as a way of thinking, science a way of investigating, science as interaction between technology and society tergolong rendah yakni dibawah 50%. Hal ini dikarenakan kemampuan berpikir kritis siswa pada tahapan penilaian, inferensi dan strategi dalam menyelesaikan masalah literasi sains masih rendah yaitu dibawah 20%. Rendahnya kemampuan berpikir kritis dikarenakan tingkatan metakognisi siswa masih rendah yakni 84% siswa berada pada tingkat kemampuan metakognisi pada tacit use dan aware use dan 16% siswa pada tingkatan strategic use dan tidak ada siswa pada tingkatan reflective use.
