Published: May 2021

O objetivo deste estudo foi realizar uma reflexão sobre desafios e caminhos para a puericultura a partir dos resultados vivenciados no seguimento de bebês nascidos a termo e prematuros tardios em uma unidade básica de saúde, no qual se pôde analisar o desenvolvimento infantil do ponto de vista do psiquismo, linguagem e motricidade. Os resultados apontam para a necessidade de se repensar os profissionais e os espaços para inserção da puericultura, tendo em vista as limitações do SUS relacionadas à inexistência de uma carreira nacional de saúde que impacta na organização hierárquica dos níveis de atenção, a ausência ou limitação na inserção de temáticas como psiquismo e linguagem na formação dos profissionais da puericultura, e as limitações educacionais familiares. Sugere-se que uma visão intersetorial e menos médico-centrada poderá ampliar possibilidades no acompanhamento do desenvolvimento infantil.

Published: May 2021

A nefropatia diabética (ND) é a principal causa de terapia de substituição renal nos países desenvolvidos e no Brasil é a segunda causa de necessidade de diálise, ficando atrás da hipertensão arterial. A identificação precoce de alterações como a diminuição da taxa de filtração glomerular e a albuminúria são cruciais para prevenir a evolução da doença. No tratamento, além do controle glicêmico, alguns fármacos para controle da pressão arterial são empregados para tratar ou mesmo retardar o desenvolvimento da ND, tais como os inibidores da ECA e os bloqueadores da angiotensina II. Há ainda os fármacos mais recentes, inibidores da SGLT2, utilizados no tratamento do diabetes que estão sendo estudados com evidências de nefroproteção e impedirem a progressão da doença. O objetivo deste trabalho foi conhecer uma das principais causas de morbidade e mortalidade em indivíduos com Diabetes Mellitus, a importância de seu diagnóstico precoce e identificar os possíveis tratamentos preventivos mais recentes como forma de não evoluir para doença renal, com enfoque nos inibidores da SGLT2. A metodologia utilizada foi a revisão literária com busca nas bases de dados Scielo, PUBMED, LILACS, MEDLINE E BVS. Os resultados comprovaram a segurança e eficiência dos inibidores da SGLT2 como adjuvantes no tratamento da ND. Os benefícios superam os riscos e medicamentos como a dapagliflozina, empagliflozina e canagliflozina devem ser prescritos aos pacientes diabéticos.

RESUMO:OBJETIVO: Comparar o controle postural de meninas adolescentes com e sem sintomas de asma, estudantes de uma escola pública, em um município da Fronteira Oeste do Rio Grande do Sul, Brasil. MÉTODOS: As meninas foram selecionadas através do questionário ISAAC (International Study of Asthma and Allergies in Childhood), que visa mostrar a prevalência de sintomas de asma, alergias e rinite. O mesmo é composto de 8 perguntas referentes aos sinais e sintomas e a última sobre diagnóstico, ao atingir a pontuação 5, o indivíduo pode ser considerado com sintomas de asma. O controle postural foi avaliado através de posturografia dinâmica computadorizada, por meio dos Testes de Organização Sensorial (TOS), divididos em seis condições sensoriais. RESULTADOS: Participaram do estudo 20 meninas de 10 anos de idade, sendo 10 do grupo controle (GC) e 10 crianças com sintomas de asma (GA). É possível observar que em ambos os grupos, o excesso de peso (sobrepeso+obesidade) esteve presente na maioria das avaliadas. As meninas com sintomas de asma apresentaram pior equilíbrio na condição II dos TOS (P=0,048), quando comparadas ao grupo assintomático, evidenciando assim, maior déficit no sistema proprioceptivo e vestibular. CONCLUSÃO: Meninas adolescentes com sintomas de asma apresentam déficit no controle postural, principalmente no sistema proprioceptivo e vestibular.

The role of media in psychological warfare
Authors: Petrović Jelena
Published: May 2021

The Gulf War represents a turning point in understanding of psychological warfare, so as the way of presenting development of war in the media. The basic means are not propagandas' messages and leaflets, anymore. The chosen reporters, the chosen journalists and the chosen TV stations have primacy. The development of technique and technology and appearance of social network services and applications creates posibillity for avoiding of war in classical meaning. The classic armed conflict creates huge economic consequences and political crysis with long-term effects. Because of it, the basic mean of fight in psychological warfare becomes disinformations and missinformations. Their ability of quick and efficient adaptation for modern technologies demands brings to the evolution into another modes of psychological warfare, such as spinn, fake news, astroturfing, social engineering. Trapped into their own pitfall because of fight for market by their insisting on interactivity with their readers and audience, the media give possibility for creating fake, made up public opinion. For now, there are two possible solutions for this situation: by canceling of access to the interactive contents either by ignoring true facts if they are not compatible with the policy of certain media or redaction (if it was shown that older course of reporting was not auspicious for them of was not true from the very beginning).

Published: May 2021

The new wave of information and communication technology transformation relies on the concepts of the Internet of Things, Big Data and machine learning. These concepts will enable the connection and independent communication of a large number of devices, the processing of data that arises as a result of these processes and learning based on the refined information. Payment system is a sector that will experience major impacts by the coming changes. A large number of transactions create an information basis, whose analysis can provide precise inputs for business decision making. The subject of paper is the impact of managing a large amount of transactional data on key stakeholders in the payment process. The aim of the paper is to identify the key advantages and dangers that the Big Data concept will bring to the payment industry. The general conclusion is that the use of Big Data tools can facilitate the timely distribution of payment services and increase the security of transactions, but the price in the form of a loss of privacy is extremely high.

Authors: Hochkirch Karsten , Brandt Hartmut
Published: May 2021

At the Institute of Naval Architecture, Marine and Ocean Engineering (ISM), Technical University of Berlin, a research project was initiated investigating prediction methods for hydrodynamic forces acting on sailing yachts.

For a 33ft. sailing yacht model tests with various keel designs and RANSE calculations have been carried out. In order to verify both, a full scale sail-force­dynamometer was built which enables to record the resulting hydrodynamic forces in a seaway without scaling parameters. In addition, separate six and five component balances have been designed for measuring the forces acting on keel and rudder for the model tests as well as on the full scale boat.

The design and construction of the full scale measuring device is presented. Along with some sample measurements a general calibration procedure for inclined multicomponent balances is proposed. A short review of the model tests and RANSE-calculations complement the presentation.
A 1997-1998 Whitbread Sail Program- Lessons Learned
Authors: Ranzenbach Robert C. , Andersson Per , Flynn David
Published: May 2021

There are many factors critical to the success of a Whitbread Round The World Race™ campaign. One of the most significant is the design, construction, and selection of an individual leg inventory of offwind sails.

As a result of the technical challenges to the experimental and computational analysis of offwind sails, shape development for this class of sails has historically relied upon empirical efforts. An added element for any advanced, state-of-the-art, sail development program is the extensive reliance upon wind tunnel results to guide sail shape improvement and leg inventory selection of offwind sails.

Lessons regarding improved offwind sail shapes, construction techniques, use of exotic materials, and sail trim learned or reinforced during the 1997-98 Whitbread Round the World Race sail development program for Swedish Match, are described with particular emphasis placed on the role of wind tunnel testing.

Published: May 2021

Thermal decomposition processes of two types of Barzas sapromixites - a tile-like modification (“tile”) and a product of its weathering (“exfoliated tile”) - have been investigated in various media (air and helium). It has been shown that in the course of temperature-programmed decomposition (10 °C/min) of these forms of tile-like Barzas sapromixite, in both oxidizing (air) and inert (helium) atmospheres, four main temperature ranges can be distinguished: 1) < 150 °C - removal of adsorbed water (this temperature region is more pronounced for the weathered form of tile-like Barzas sapromixite); 2) 150-350 °C - removal of low molecular weight volatile components of coal in helium environment (with their simultaneous ignition in case of the decomposition in air); 3) 350-550 °C - the temperature region of primary or fast coal pyrolysis in an inert medium; in an oxidative medium, this stage of pyrolysis is accompanied by the burning of released tarry substances; 4) > 550 °C - the temperature region of secondary or high-temperature coal pyrolysis to form semi-coke in helium atmosphere, or the region of burning this semi-coke in air medium. Thermal breakdown processes of “exfoliated tiles” in the temperature range of the most intensive decomposition (350-550 °C) have been found to require less energy consumptions than the similar processes for tile-like Barzas coals (by 72-73 kJ/mol for both gas media of thermal treatment). It is supposed that the differences observed in thermal behavior of Barzas sapromixite forms under investigation may be related to the different contents of mineral components and their effects on the thermal decomposition of coal organic matter.

Published: May 2021

The paper investigates the possibility of using SKS-30 ARK as a promising coagulant of triethanolamine and its salt in the technology of producing styrene-butadiene rubber. It was found that complete coagulation in the presence of triethanolamine occurs only at high consumption of its acidifying agent (sulfuric acid solution). Otherwise, complete coagulation is not observed. This is due to the fact that aqueous solutions of triethanolamine have an alkaline medium, and in this medium the aggregate stability of latex is greatest. It is noted that an increase in the consumption of triethanolamine in the process of coagulation not only does not increase the yield of rubber crumbs, but also leads to an increase in the consumption of the acidifying agent. It was found that to eliminate this disadvantage, it is possible to use the triethanolamine salt-triethanolamine hydrochloride. This solution was obtained from aqueous solutions of triethanolamine and hydrochloric acid, using homogenization. When triethanolamine hydrochloride is used as a coagulant, the process of separating rubber from latex proceeds by a neutralization mechanism. It was found that it is possible to use triethanolamine hydrochloride as a coagulant in lower dosages than sodium chloride and triethanolamine. It should be noted that the aqueous phase formed during the coagulation process in the presence of triethanolamine hydrochloride can later be returned to production as a solvent in the preparation of aqueous solutions of the acidifying agent and coagulant. At the same time, triethanolamine has anti-corrosion activity, which is a positive point for processes where strong sulfuric acid is used. It is established that the physical and mechanical characteristics of vulcanizates obtained on the basis of rubbers made in the presence of triethanolamine hydrochloride meet the requirements of the standard.

Published: May 2021

Electrochemical oxidation of graphite powder in 58% HNO3 was studied. Samples of oxidized graphite were obtained with a imparting of the amount of electricity 500, 700, 1500 mAh g-1. The character of the galvanostatic dependencies allows to select a region of the formation of intercalated compounds of graphite prior to the accumulation of quantity of electricity of 500 mA h g-1. It was found that when the quantity of electricity of over 700 mA h g-1 the process of electrochemical peroxidation of intercalated graphite begins with the formation of multilayer graphene oxide, as confirmed by comprehensive studies using X-ray diffraction, scanning electron microscopy, FTIR spectroscopy, laser diffraction. The synthesized multilayer graphene oxide is characterized by the presence of a spectrum of oxygen-containing functional groups, mainly hydroxyl, as well as carboxyl, epoxy and alkoxyl. X-ray images show a peak at 2θ = 11.45° which intensity increases for re-oxidized graphite compounds and also indicate the formation of a multilayer graphene oxide with an interlayer distance of 7.8 Å. The synthesized material in aqueous suspensions under the action of ultrasound is dispersed with a 7-11-fold reduction in particle size. Graphene layers remains layered structure but the degree of their deformation increases, and the thickness of the layers decreases with an increase in the imparted amount of electricity.

Published: May 2021

The paper considers the main components and products of wood processing, agricultural waste, pulp and paper industry waste and qualifies them as sources of pentose-containing resource-renewable domestic raw materials. The article describes in detail the structural components of wood as a natural polymer, which contains aromatic and carbohydrate parts. It is noted that these poly-mers are promising as raw materials for the production of useful chemical products. The role of lignin, cellolose and hemicellulose in the design of mechanical and structural properties of wood is considered. The article considers the features of the sulfonation reactions of the lignin monomer unit depending on the pH of the medium: acidic, neutral and alkaline. There are three main reac-tions that occur simultaneously with lignin in the process of wood delignification during sulfite cooking, such as the sulfonation reaction, the hydrolytic destruction reaction, and the condensation reaction. It is shown that the lignin-hemicellulose matrix contains three types of interconnected mesh structures: the lignin itself; a network of covalent bonds of lignin with hemicelluloses, and a network whose structure is obtained due to the hydrogen bond and the forces of the physical inter-action of lignin and hemicelluloses. The features of chemical transformations of the monomeric aromatic link of lignosulfonate – phenylpropane unit in the processes of wood delignification, the main chemical reactions of wood raw material delignification under the conditions of sulfite and neutral-sulfite brews are shown. The method of quantitative determination of monosaccharides in the composition of the carbohydrate part is proposed.

Published: May 2021

The paper presents the results of a study evaluating the effect of the addition of nanosized detonation diamond of the NA-SP brand on the characteristics of a filled polymer composition based on SKU PFL-100 prepolymer manufactured by Kazan Synthetic Rubber Plant JSC cured by 4,4'-methylene-bis-orthochloraniline. The scale of heterogeneity of the carbon powder was estimated. It is shown that the studied additive allows you to create a fairly dense and developed structure in a dispersion medium. The discussion of interfacial interaction at the nanodiamond – polyurethane interface is carried out, as well as the influence of the carbon nature of the filler particles. A possible chemical interaction between the functional groups of the prepolymer, hardener and particles of the studied additives is shown. The results of the experimental evaluation show that the combination of chemistry features (the presence of functional groups) and the mechanics of nanodiamond powder affects both the physical and mechanical properties of the filled polyurethane composition and its thermal stability. It was found that the introduction of up to 1% detonation diamond allows to increase the strength and stiffness of the polymer by approximately 2 times. As a result of the approximation of the experimental data, quadratic dependences of the physical and mechanical characteristics of the filled polyurethane system on the content of nanoscale diamonds in the range 0 - 1% (mass.) were obtained. The results of thermogravimetric analysis show that the introduction of 1% (mass.) detonation diamond powder can increase the temperature of destructive processes by about 20 °С. Anomalies in the dynamics of the process of dissociation of filled polyurethane are noted. It has been suggested that the introduction of detonation diamond leads to the initiation of secondary synthesis reactions with the formation of allophate and biuret groups with low temperature stability.
5-(R)BENZYLIDENE-2,2-DIMETHYL-1,3-DIOXANE-4,6-DIONES IN SYNTHESIS OF AROMATIC OXIMES, THIOSEMICARBAZONES AND HYDRAZONES

Published: May 2021

The behavior of some derivatives of Meldrum's acid, namely, 5-(R)benzylidene-2,2-dimethyl-1,3-dioxane-4,6-diones (a well-known synthetic platform) was studied with mono- and biazanucleophiles (hydrochloric hydroxylamine, thiosemicarbazide, hydrazine hydrate). The reaction of the reagents was carried out in acetic acid in a 1:1 molar ratio at 75 °C for 6-8 h, which resulted in aromatic oximes, thiosemicarbazones and hydrazones. The synthesis of (E)-4-chlorobenzaldoxime, (E)-N-(4-nitrobenzylidene) hydroxylammonium chloride, (E)-2-(4-chloro)- and (E)-2-(4-nitrobenzylidene) hydrazine-1-carbothioamides is probably accompanied by the formation of the Michael β-adduct with the subsequent elimination of Meldrum's acid. The interaction of nitrobenzylidene dioxanedione with hydrazine hydrate occurs to form a mixture of (E)-N-(4-nitrobenzylidene) acetohydrazide, (E)-(4-nitrobenzylidene) hydrazine and acetate of the latter in a ratio of 17:3:1, found from the integral signal intensity in the 1Н NMR spectrum (the ratio of similar products was 6:2:1 for chlorobenzylidene dioxanedione). It has been shown that during the reaction the studied substrates are attacked by two hydrazine molecules at the arylidene fragment and the carboxyl group of the opened dioxane cycle of Meldrum's acid. Further, the intermediates are recondensed to form hydrazones and acetylhydrazides. The latters interact with the aromatic aldehydes arising under these conditions as a result of the Knoevenagel retro-reaction of the substrates, with the formation of major products, mixtures of (E)-N-(4-chloro)- or (E)-N-(4-nitrobenzylidene) acetohydrazides. Thus, under the selected conditions, in contrast to the common mechanism presented in the periodicals, no formation of N-heterocyclic systems is observed. The structure of the compounds obtained was confirmed on the basis of 1H, 13C NMR spectroscopy data, as well as elemental analysis. Methods of two-dimensional heteronuclear correlation spectroscopy (HSQC) were also used for more reliable identification of the signals of the products (the components of mixtures).

Published: May 2021

Purpose: Antithyroid drugs (ATDs) are primarily used as an initial treatment in pediatric patients with Graves’ disease (GD). We aimed to investigate the long-term outcomes in pediatric GD patients receiving ATDs.Methods: Retrospective data from a single center were collected from April 2003 to July 2020. A total of 98 children and adolescents aged 2–16 years diagnosed with GD and receiving ATDs was enrolled. We investigated the factors correlated with remission by comparing children who achieved remission after 5 years and those with persistent disease.Results: The study included 76 girls (77.6%) and 22 boys (22.4%). During the 5-year follow-up period, 18 children (18.3%) maintained remission, ATDs could not be discontinued in 74 patients (75.5%), and relapse occurred in 6 patients (6.2%). The remission group had significantly lower thyroid-stimulating hormone-binding inhibitory immunoglobulin (TBII) level at diagnosis (P=0.002) and 3 months (P=0.002), 1 year (P=0.002), 2 years (P≤0.001), 3 years (P≤0.001), 4 years (P≤0.001), and 5 years (P≤0.001) after ATD treatment than did the nonremission group. The remission group also had a shorter time for TBII normalization after ATD treatment (P≤0.001). Multiple logistic regression analysis showed that the time to TBII normalization (cutoff time=2.35 years) was related to GD remission (odds ratio, 0.596; 95% confidence interval, 0.374–0.951).Conclusion: TBII level and time to TBII normalization after ATD treatment can be used to predict remission in pediatric GD patients.

“The lady who dared” – an examination of the 1914 Dronfield school strike
Authors:   , Whitfield Paul Leon
Published: May 2021

This study explores the events of the Dronfield school strike of 1914. In doing so it considers the personal experiences of those centrally involved and the impact of events on them. The core aim of the study is to consider how much the Dronfield events were initiated and driven by the reformist actions of one woman, headteacher of Dronfield Elementary School Girls’ Department Sarah Outram; how much they were the expression of conflicting social forces prevailing in the early years of the twentieth century; and how much the specific circumstances prevailing in the town of Dronfield created the atmosphere in which the school strike could occur. This study examines a wide range of primary source material relating to the Dronfield school strike. Some of the primary sources, such as the file of the Board of Education investigation, have been considered by earlier historical studies, but this study examines sources not explored before. These include the widespread newspaper coverage, and documents about the pre-existing conflict between the Dronfield school managers and the Derbyshire Education Committee, which formed a backdrop to the strike events. The study places the Dronfield event in the wider context of the social movements of the early 20th century, including the struggle for women’s suffrage and debates around feminism, sex education, social purity and eugenics. It then focusses on the particular circumstances in Dronfield and examines how events were shaped by the actions, motives and beliefs of people within the town. The study shows how tensions around social issues existed across the country, but only in Dronfield did they combine with local circumstances to provoke and sustain the unique phenomenon of the Dronfield school strike. In doing so the study presents an example of the impact wider social movements could have on everyday life at a local level.

Published: May 2021

Nursing career paths in public health centers have not been well established compared with nurses in hospitals. It is because the nursing career path has a different organizing system, which then becomes an obstacle in implementing the career path for nurses in primary health care. Therefore, this study aimed to identify the relationship between institutional and nurses’ readiness in implementing nursing career paths within public health centers. A cross-sectional study design with questionnaire as instrument was used in this research. A consecutive sampling technique was used to select 93 nurses from 13 public health centers. Furthermore, to identify the objective of this research, the Spearman’s correlation coefficient was used to determine the relationship between paired data. The results found that institutional readiness was 64 or 71.9% of maximum values, yet nurses’ readiness was 112 or 74.5% of maximum values. Thus, it can be concluded that there was a meaningful relationship between institutional and nurses’ readiness with career path implementation (p< 0.001), indicating a strong positive relationship (r= 0.521). The results of this study are expected to become a baseline data for public health centers and public health offices to establish a professional nursing career path in public health centers. Abstrak Kesiapan Individu Berhubungan dengan Kesiapan Institusi dalam Penerapan Jenjang Karir Perawat di Puskesmas.

Published: May 2021

The Malaysia Ministry of Health reported adolescents’ low utilization of healthcare services, although they need this service as a consequence of their involvement in risky behavior. This cross-sectional study aimed to determine adolescents’ perception on risk-taking behavior and their utilization of health care services. A modified self-administered questionnaire was used to collect data from 250 secondary school students aged 13 and 14 years in one of the selected schools in Malacca, Malaysia. Data were analyzed using SPSS 20. Fast-food consumption, loitering after school, physical fighting, smoking, and non-use of helmets were the most reported risky behaviors among adolescents in Malaysia. More than half of the adolescents who knew about health care services had a positive perception on their utilization of such services. Thus, the promotion of adolescents’ health services helps increase their use of these services and consequently achieve a healthy lifestyle. Abstrak Persepsi Siswa Sekolah terhadap Perilaku Risiko dan Pemanfaatan Layanan Perawatan Kesehatan.

Authors: Crisan Adina V. , Vancea Ion V.
Published: May 2021

In this paper, we review recent results on the interaction of the topological electromagnetic fields with matter, in particular with spinless and spin half charged particles obtained earlier. The problems discussed here are the generalized Finsler geometries and their dualities in the Trautman-Ra\~{n}ada backgrounds, the classical dynamics of the charged particles in the single non-null knot mode background and the quantization in the same background in the strong field approximation.
The Transformation of Commutative Phase Space to Noncommutative One, and its Lorentz Transformation-Like Forms
Authors: Nakamura Makoto , Kakuhata Hiroshi , Toda Kouichi
Published: May 2021

Noncommutative phase space of arbitrary dimension is discussed. We introduce momentum-momentum noncommutativity in addition to co-ordinate-coordinate noncommutativity. We find an exact form for the linear transformation which relates a noncommutative phase space to the corresponding ordinary one. By using this form, we show that a noncommutative phase space of arbitrary dimension can be represented by the direct sum of two-dimensional noncommutative ones. In two-dimension, we obtain the transformation which relates a noncommutative phase space to commutative one. The transformation has the Lorentz transformation-like forms and can also describe the Bopp's shift.
Generalized Weyl Quantization and Time
Authors: Romeo Daisy A. , Nable Job A.
Published: May 2021

This work presents quantization of time of arrival functions using generalized Stratonovich-Weyl quantization. We take into account the ordering problems involved, mainly the Born-Jordan and the symmetric ordering schemes. We call attention to the combination of the group theoretic methods usually employed in Weyl quantization with the implementation of different ordering schemes via integral kernel factors. It is possible to, and we do, apply the Pegg-Barnett method to the quantization of time to address physical issues such as boundedness and self-adjointness.
You Have One New Message
Authors: Aktas Bilge Merve
Published: May 2021

Knitting is often practiced as a group activity that takes place in the domestic environment. Besides the collectivity, using motifs with meanings has also facilitated communication between people. Building on these ideas, a workshop was designed to facilitate discussions about everyday concerns or experiences, both on personal and societal levels, to strengthen communication with the self and others. In the workshop, the thirteen participants were asked to design a motif to convey a message to themselves, to the group or to the society. Through a group discussion, the motifs stemming from personal experiences were knitted, shared and discussed. The topics emerging from the workshop indicates that knitting affords intimate exchanges between the self and others, and connects people by facilitating socio-political discussions, such as on environmental sustainability, women rights and self-development.
Twist-hands and shuttle-kissing
Authors: Penny Simon , Fisher Tom
Published: May 2021

This paper seeks to understand the skills of operating automated manufacturing machines of the C19th as craft practices, employing externally powered and automated tools around which new cultures of practice emerged. We draw upon situated/embodied/enactive/extended/distributed (SEEED) approaches to cognition to explicate the sensibilities of these practices, as well as the history of science and technology, Anthropology, STS and related fields. Our case study is a body of work focused on embodied/ embedded knowledge in the textile industry – specifically in the making of machine lace. We conclude with a proposal for multi-modal museum exhibits that provide an understanding of know-how, kinesthetic/proprioceptive skills and procedures. The authors are both long term practitioners of crafts, both traditional and industrial (see bios). This experience informs the research at every step.
Knowledge transfer in heritage cultural craft, damask weaving
Authors: Jönsson Clary
Published: May 2021

The hand weaving of damask is no longer a craft that is commonly learned and very few books on the subject have been published in the last century. Damask weaving still exists among private practitioners, but what happens to the knowledge when nobody knows how to dress a loom and weave anymore?  The aim of this study is to describe and compare damask weaving from a learning perspective in order to generate knowledge of how damask weaving is described in the literature and how the knowledge is communicated to increase understanding of the learning process and to generate a theoretical understanding of practical knowledge transfer. The method used is a literature study and open interviews with people who teach damask weaving. The study shows that the literature does not provide enough information on how to dress and weave damask. The interviews give a deeper understanding of the practical knowledge. The analysis shows that it is difficult to use only cognitive reading as interpretation from the body and hands are needed and the different steps need to be dissected in detail.
Linear Algebra, Computational
Authors: Durón Christina
Published: May 2021

Computational linear algebra is the study of numerical algorithms used to solve linear algebra problems on computers. Consequently, the field can be divided into three parts: discrete computations, constrained optimization, and numerical linear algebra. Due to limitations of space, only the most important topics of numerical linear algebra are discussed. These topics include matrix decompositions, iterative methods for systems of linear equations, updating methods, the underlying principles of numerical stability, accuracy of computed solutions, and high‐quality mathematical software. For each topic, a short overview and best practices are discussed. In selecting or developing methods for solving a problem in computational linear algebra, it is necessary to have an understanding of each of these main features.

Published: May 2021

In this study, effects of different yttrium (Y) contents ranging from 0 to 2.5 wt% on the microstructure and tension/compression asymmetry of as‐extruded Mg–5.5Zn–0.6Zr alloys are investigated. The influence of Y on improving the tension/compression yield strength is been studied. The results show that the volume fractions of the microscale I (Mg3YZn6) and W (Mg3Zn3Y2) phases remarkably increase with Y addition. Simultaneously, the nanoscale MgZn and Mg–Zn–Y phases uniformly precipitate during extrusion. Benefiting from the pinning of second phases, the microstructure is strikingly refined from 16.3 to 5.5 μm. Among them, the Y element promotes grain refinement most effectively when the Y content is 2.0 wt%. Second phase strengthening and fine‐grain strengthening enhance the hardening rate and suppress twinning, which leads to the improvement of the tension/compression asymmetry. Specifically, yield strength of 231 MPa and ultimate tensile strength of 312 MPa are achieved with 2.5 wt% Y addition. The relative increment is about 33.0% and 65.3% compared to the unmodified alloy, respectively. In addition, the tensile yield strength to compressive yield strength ratio (TYS/CYS) is reduced from 1.30 to 1.09.
Lightweight Ni Foam‐Based Ultra‐Broadband Electromagnetic Wave Absorber

Published: May 2021

Skin effect and high density are the main reasons that restrict the search of lightweight and high‐performance metal‐based electromagnetic (EM) wave absorbing materials. Although nanostructured metal materials have been fabricated to solve above problems, poor dispersibility and chemical stability issues brought about by high surface energy due to existing nano‐size effect. In this work, lightweight Ni foam with NiO/NiFe2O4 in situ growth composites are fabricated by a facile and universal route as an effective alternative to high‐performance metal‐based EM wave absorber. Impressively, it is found that the foam structure and NiO/NiFe2O4/Ni components can synergistically boost EM wave absorption capacity. In detail, impedance matching from foam structure and energy dissipation from interfacial polarization and defect induced polarization provided by NiO/NiFe2O4 mainly contributes to its ultra‐broadband EM wave absorption performance. As a result, the as‐prepared sample (0.06 g·cm−3) delivers a wide absorption bandwidth of 14.24 GHz and thin thickness of 0.6 mm, as well as, high specific effective absorption bandwidth of 19444.4 GHz·g−1·cm−2. This work sheds light on the novel view on the synergistic effect of structure and components on EM wave absorption behaviors and demonstrates a new pathway for preparation of lightweight and high‐performance metal‐based EM wave absorbers.

Published: May 2021

Predicting the performance of thermoelectric generators (TEGs) is an essential part of designing high‐performance TEGs. However, due to the complexity of the TEG system, the existing methods are either time‐consuming or not precise enough, inconvenient for device optimization. In this paper, the deep learning (DL) method to fast and accurately get the performance of TEG devices is presented. First, the key features of a typical TEG device are captured and the training dataset is prepared based on the extracted features and finite element simulations. Next, a proper deep neural network architecture is acquired and the model is trained to converge at a low loss. Finally, the experimental data is used to validate the generalization ability of the presented model. Besides, the device optimization based on the DL solution is performed and an output power enhancement of up to 182% is achieved for the authors’ sample module. The presented DL solution thus can be well applied in designing or optimizing high‐performance TEGs. Furthermore, the established framework also sheds considerable light on applying the DL approach to solve general engineering problems.

Published: May 2021

Surface‐enhanced Raman spectroscopy (SERS) is a powerful analytical tool to detect molecular species at ultralow concentrations. However, considering current approaches, controlling and tuning plasmonic hot‐spot formations where the Raman signal enhancements maximize are still challenging due to high process cost, complexity, and inability of large‐area fabrication. To address these problems, a strategy is demonstrated based on the controlled folding of polymeric materials, which is a new perspective in the field of SERS. Manipulation of hot‐spot formations through controlled polymer folding enables a Raman signal enhancement up to 70 folds for the probe methylene blue molecule. Furthermore, sample collection and analysis have been successfully implemented through the magnetic field control of the platform motion and folding manipulation. The results demonstrate that soft actuator platforms can bring new modalities in sensing applications.
