Color polymorphism in organic crystals
Authors: Nogueira Bernardo A. , Castiglioni Chiara , Fausto Rui 
Published: March 2020

AbstractColor polymorphism is an interesting property of chemical systems which present crystal polymorphs of different colors. It is a rare phenomenon, with only a few examples reported in the literature hitherto. Nevertheless, systems exhibiting color polymorphism have many potential applications in different domains, such as pigment, sensor, and technology industries. Here, known representative chemical systems showing color polymorphism are reviewed, and the reasons for them to present such property discussed. Also, since some of the concepts related to color polymorphism have been frequently used imprecisely in the scientific literature, this article provides concise, systematic definitions for these concepts.
Formation of thioglucoside single crystals by coherent molecular vibrational excitation using a 10-fs laser pulse

Published: March 2020

AbstractCompound crystallization is typically achieved from supersaturated solutions over time, through melting, or via sublimation. Here a new method to generate a single crystal of thioglucoside using a sub-10-fs pulse laser is presented. By focusing the laser pulse on a solution in a glass cell, a single crystal is deposited at the edge of the ceiling of the glass cell. This finding contrasts other non-photochemical laser-induced nucleation studies, which report that the nucleation sites are in the solution or at the air-solution interface, implying the present crystallization mechanism is different. Irradiation with the sub-10-fs laser pulse does not heat the solution but excites coherent molecular vibrations that evaporate the solution. Then, the evaporated solution is thought to be deposited on the glass wall. This method can form crystals even from unsaturated solutions, and the formed crystal does not include any solvent, allowing the formation of a pure crystal suitable for structural analysis, even from a minute amount of sample solution.

The article deals with the feature’s projects portfolio formation of head enterprise that produces high-tech products. Methods the projects portfolio formation are considered: mathematical, simulation and economic-statistical. The factors that influence the choice of the model are illustrated.It is proposed to carry out research on the basis of creation complexes ofinterrelated, multi-level models and optimization-simulation approach. Themeans of implementing this approach are human-machine iterative,interactive procedures. To find the optimal solution by the decision maker,procedures should be based on the identification of the main goals andpreferences used in the creation of an optimal of the project portfolio, thestudy of a set of acceptable parameters and actions.
The head enterprise is considered as a complex system described by severalmodels, to which the control scheme with direct and feedback is applicable,where:
functional breakdown of the process of forming the projects portfolio into separate blocks justifies the use of multi-level modeling of a complex production system;
in long-term planning and forecasting, it is necessary to solve both the direct problem of system consequences for a given “input”, and the inverse problem of planning, which has a significant spread of output parameters. In order to optimize the method, it is proposed to create iteration- optimization analytical models using the two-point boundary value method, including planning from the achieved and planning from the final result. Indicated the advantages of using a specialized mathematical apparatus inthe formation of the projects portfolio.
Formation of working environment and capacity of a management at the enterprise
Authors: Zotov Fedor 
Published: March 2020

The formation of a methodology of a supporting of a development of an enterprise management system is a direction of the author’s research. As part of the study in this work, it seemed appropriate to present the author’s point of view on understanding the place of management in a modern industrial enterprise. In management theory, interpretations of similarities and differences in the contents of the terms “management” and “administration” are found. In this work, a comparative analysis of the concepts of “management” and “business administration” is carried out. In determining these concepts, the functional content, essence and relationship of management and business administration in the enterprise are highlighted. Based on the analysis, the management potential is formed. Management aspects of the activity are identified as such potential. As a working environment for the implementation of management potential, flows are defined. The main flows constituting the activities of the enterprise are presented. A stream visualization tool, the Senkai diagram, was brought in. The visualization of the flows made it possible to identify the area of application of the management potential, both for solving the current practical problems of the business and for the development of the enterprise management system.It is proposed to consider the results of the study as an approach to solving the urgent problem of streamlining an expensive managerial resource in the enterprise. The analysis of the achievements in solving this problem, published in domestic and foreign literature and related to overcoming the existing state in the management activities, is carried out. The causes of the problem are highlighted. An analysis of the reasons led to the conclusion that, within the framework of the existing approaches to management, the manager cannot carry out full-fledged effective activity. A generalization of the research results made it possible to identify the main directions for solving the problem. Mostly this decision is expressed in increasing the effectiveness of the actions of officials at different levels of the hierarchical structure, that is, in the chain of relations “leader - subordinate.” In this study, the author proposed an approach to solving the problem, which consists in eliminating the overlapping responsibilities of managers at the hierarchical levels of the administrative structure. This approach involves the transformation of the structure.

Published: March 2020

ZusammenfassungFür Patienten mit hereditären Netzhautdystrophien (auf Englisch: inherited retinal dystrophies, IRD) ist die Früherkennung, Differenzialdiagnose und mögliche Therapieentscheidung von erheblicher persönlicher und sozialer Bedeutung. Für den Augenarzt kann dies aufgrund der Heterogenität der Erkrankungen und Verläufe sowie der Seltenheit der IRD eine Herausforderung sein. Die vorliegende Übersicht empfiehlt eine zielorientierte klinisch-ophthalmologische Diagnostik bei Verdacht auf IRD mit einer Bewertung der Relevanz der einzelnen Methoden und ihrer Kombination für Diagnose, Differenzialdiagnose und Beurteilung der Progression im Verlauf. Nach einer umfassenden Anamnese ist initial die Kombination von optischer Kohärenztomografie (OCT), Fundus- und Nahinfrarot-Autofluoreszenz zur Frühdiagnose einer IRD ggf. vor ophthalmoskopisch sichtbaren Läsionen sinnvoll. Spektrale Reflexionsfotografie, OCT-Angiografie und Fluorescence Lifetime Imaging Ophthalmoscopy sind bei einzelnen IRD hilfreich. Erlaubt die retinale Bildgebung keine sichere Diagnose, ist das multifokale Elektroretinogramm zur Frühdiagnose und das Ganzfeld-Elektroretinogramm zur Differenzialdiagnose von IRD geeignet. Eine Vorstellung in Schwerpunktzentren für IRD zur Differenzialdiagnostik und Therapie ist empfehlenswert.

Resumo
Objetivo Este estudo teve o objetivo de analisar a associação entre a osteoartrite (OA) de joelho e a síndrome metabólica (SM) em pacientes idosos não institucionalizados.
Métodos Pesquisa transversal, aleatorizada, extraída de um estudo probabilístico por conglomerado realizado com 416 idosos de uma Unidade de Saúde da Família do nosso município. A SM foi definida de acordo com o National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III), e a OA de acordo com a escala Kellgren-Lawrence (KL) (≥ 2).
Resultados Para a análise estatística, foi realizada uma análise exploratória de dados, testes de Mann-Whitney ou Qui-quadrado e regressões logísticas uni e multivariadas, com nível de significância de p < 0,05; a concordância entre os avaliadores foi verificada através do coeficiente de Kappa. Verificou-se associação entre OA e índice de massa corpórea (IMC) (p = 0,0021) e entre OA e circunferência de cintura (CC) (p < 0,001; razão de chances [RC] = 3,524). Não foi encontrada associação significativa entre a OA e o número de componentes metabólicos nem com a SM em si.
Conclusão Conclui-se que a OA de joelho associa-se à CC, independente do peso, e que o aumento em sua medida reflete em uma maior chance de SM em idosos não institucionalizados.

ResumoA doença de Freiberg é rara, e seu diagnóstico requer alto grau de suspeita clínica. A necrose avascular da cabeça do metatarso progride com colapso articular, e causa dor no antepé e limitação da atividade.Há diversas técnicas cirúrgicas para o tratamento da doença; como o diagnóstico geralmente é feito em estágios posteriores, a maioria dessas técnicas inclui procedimentos de destruição articular.A artroscopia tem sido utilizada nas pequenas articulações do pé nos últimos anos, mas sua aplicação na doença de Freiberg ainda é escassa. Procedimentos de preservação articular têm sido preconizados na doença em estágio inicial, com o objetivo de aliviar os sintomas e impedir a progressão.Neste relato, descrevemos o tratamento bem-sucedido de uma paciente de 12 anos de idade com doença de Freiberg em estágio inicial por meio de descompressão central e enxerto de medula óssea, por meio de abordagem minimamente invasiva assistida por artroscopia.
Functionally Crippled Nose

Published: March 2020

AbstractNasal obstruction is a common presenting symptom of patients seen by primary care physicians, otolaryngologists, and facial plastic surgeons. A variety of treatment strategies, both surgical and nonsurgical, have been used with success in improving nasal obstruction and quality of life. In a subset of patients, many of whom have either attempted these common treatment strategies or are intolerant of them, nasal obstruction remains a significant symptom. In these patients, there may be an identifiable problem, but it is simply not repairable or there is no identifiable anatomic issue. The management of these patients is discussed in this article, with an emphasis on a sensitive approach that takes into consideration a patient's mental health. While the need for diagnostic testing is generally not necessary for most cases of nasal obstruction, endoscopy and imaging should be considered in these patients. Validated patient-reported outcome measures are particularly helpful in providing an objective measure to a patient's frustrating symptoms. A variety of medications can be either contributory to the patient's symptoms or therapeutic if used appropriately. A variety of surgical interventions can also result in a functionally crippled nose and diagnoses including nasal valve stenosis, septal perforations, and empty nose syndrome are discussed. Importantly, further surgical interventions may not be appropriate if a deformity is minimal, and a surgeon should resist the temptation to proceed with surgery in those situations.
Role of Computerized Tomography in Evaluation of Coronary Bypass Grafts—Special Reference to Women
Authors: Patnaik Sujata , Murty Sri Rama , Rao Amaresh , Rammurti Susarla 
Published: March 2020

AbstractComputerized tomography-coronary angiography (CT-CAG) is gaining popularity as an alternative to conventional CAG to evaluate grafts in a post-coronary artery bypass graft (post-CABG) patient, since it is a noninvasive procedure and is less influenced by cardiac motion. The primary challenge is to image a rapidly beating heart. With introduction of 64-slice scanner, the coronary imaging became a possibility with acceptable accuracy. In recent years, with the development of 128,256 and 320 multislice CT scanners, further enhancement in the temporal and spatial resolution is achieved due to lesser influence of the respiratory and cardiac motion, enhancing the accuracy of the lesion assessment in the grafts and the native vessels. Achieving low heart rate and artifact-free image acquisition, proper reconstruction, and image interpretation are challenges to the radiologists and the technicians involved in coronary imaging. Women pose special subset because of smaller sized coronary vessels, interference due to breast shadows, low-referrals, and gender-specific reluctance to accept the procedure itself. Cardiologists and radiologists caring for these patients must be familiar with the pros and cons of CT-CAG and gender-specific challenges.
Science, advocacy, and quackery in nutritional books: an analysis of conflicting advice and purported claims of nutritional best-sellers
Authors: Marton Rebecca M. , Wang Xindi , Barabási Albert-László , Ioannidis John P. A. 
Published: March 2020

AbstractNutritional decisions may be important for health, and yet identifying trustworthy sources of advice can be difficult to achieve. Many people turn to books for nutritional advice, making the contents of these books and the expertise of their authors relevant to public health. Here, the top 100 best-selling books were identified and assessed for both the claims they make in their summaries and the credentials of the authors. Weight loss was a common theme in the summaries of nutritional best-selling books. In addition to weight loss, 31 of the books promised to cure or prevent a host of diseases, including diabetes, heart disease, cancer, and dementia; however, the nutritional advice given to achieve these outcomes varied widely in terms of which types of foods should be consumed or avoided and this information was often contradictory between books. Recommendations regarding the consumption of carbohydrates, dairy, proteins, and fat in particular differed greatly between books. To determine the qualifications of each author in making nutritional claims, the highest earned degree and listed occupations of each author was researched and analyzed. Out of 83 unique authors, 33 had an M.D. or Ph.D degree. Twenty-eight of the authors were physicians, three were dietitians, and other authors held a wide range of jobs, including personal trainers, bloggers, and actors. Of 20 authors who had or claimed university affiliations, seven had a current university appointment that could be verified online in university directories. This study illuminates the range of the incongruous information being dispersed to the public and emphasizes the need for future efforts to improve the dissemination of sound nutritional advice.
Framing economic inequality in the news in Canada and the United States
Authors: Baumann Shyon , Majeed Hamnah 
Published: March 2020

AbstractNews frames are the interpretations and emphases in the presentation of complex issues that privilege certain understandings over others. We take the case of the framing of economic inequality in the news in order to make an empirical contribution and a conceptual contribution. The framing of economic inequality in news coverage is important to understand as news frames can shape public opinion and subsequently policy responses to inequality. There is no research we are aware of that documents how economic inequality is framed in the news. We compiled a dataset of 2109 news articles, published between 2000 and 2014, about economic inequality, and conducted a detailed content analysis. Empirically, we document how inequality was framed as an issue, specifically whether it was framed as a social problem with negative consequences, and what its causes, consequences, and solutions were. Conceptually, we also address an important gap in knowledge about the determinants of news frames. Research about how news frames are shaped by contextual factors in the production of news is uncertain about which factors matter and to what extent. The dataset has a set of features that allow us to simultaneously examine a number of potential determinants of news frames. Our data allow us to compare the relative influences on news coverage of economic inequality of (1) national context, (2) the political leaning of newspapers, (3) changing economic conditions, and (4) social movement efforts. Of these four factors, we find that only the Occupy movement influenced the volume of attention and the identification of economic inequality as a problem with negative consequences. National context, political leaning, and change in economic conditions had much more limited, or no, influence. Following the emergence of the Occupy movement, attention to economic inequality increased and remained higher than before. However, despite the clear effects of the Occupy movement on problem identification, news coverage of the causes and solutions to economic inequality did not significantly shift. We, therefore, find that social movement activity had the clearest influence on news frames, but the observed effect in this case was superficial rather than detailed.
The impact of translated Harry Potter on children’s
fantasy literature system in South Korea
Authors: Shin Jisun 
Published: March 2020

Abstract
This study examined the impact of translated Harry
Potter series on Korea’s literature system, adopting Even-Zohar’s
polysystem theory. Literature review shows that (1) discourses on children’s
fantasy literature increased; (2) the number of the country’s original
children’s fantasy books apparently inspired by Harry Potter
rose; (3) the country’s discourses about children’s fantasy literature began to
focus more on its own originals and their distinctive features. This indicates
that translated Harry Potter moved to the centre in Korea’s
children’s literary system. And this is mainly attributed to the weakness of the
country’s fantasy literature system. This research is based on Even-Zohar’s
polysystem theory which is considered an effective framework to describe the
dynamic and competitive interplay between systems, and it is significant as the
first attempt to explain the rise of translated fantasy children’s books in
Korea’s children’s literature system in the wake of the sweeping popularity of
translated Harry Potter.
The syntax of intensifiers in Muishaung
Authors: van Dam Kellen Parker 
Published: March 2020

Abstract
The Tangsa-Nocte languages of the India/Myanmar border region employ a system of suffixes to modify descriptive
words. These may be reduplicated under certain conditions, determined by the stress patterns of the larger utterance. Previously
referred to as intensifiers (Morey n.d.; van Dam 2018), these affixes modify their stems to cover a wide range of different meanings, with each
stem having a limited and sometimes unique set of applicable modifiers. Such intensifiers are found throughout the Pangwa
varieties of Tangsa-Nocte and occur with the majority of basic adjectives derived from monosyllabic verbal stems.
Suppression of (Cu,Ni)6Sn5 Intermetallic Compound in Sn-0.7Cu-0.05Ni+1wt.TiO2 Solder Paste Composite Subjected to Isothermal Aging
Authors: Mohd Said R , Saud N , Salleh MAA Mohd , Derman M N 
Published: March 2020

Abstract
This paper investigated the intermetallic compound (IMC) layer that formed in Sn-0.7Cu-0.05Ni+1wt.% TiO2 (SCNT) composite solder paste added with reinforcement (TiO2) particles. Besides, the growth of the IMC layer during subsequent aging at temperature of 75 °C, 125 °C and 150 °C also being studied. Scanning electron microscopy was used to observe the IMC growth and to measure the thickness of IMC layer. The interfacial IMC layer has been suppressed whereas the activation energy value of the composite solder paste was high (37.35 kJ/mol) which in turn improved the thermal stability of the IMC layer. Results also show the IMC formed at bulk solder microstructure of SCNT solder paste composite was refined. The presence of TiO2 particles has become the obstacle for the Cu atom diffusion from the substrate to the solder and Sn atom from the solder, thus, successful for the suppression of the IMC layer.

Abstract
This research focus on the effect of polyethylene glycol (PEG) on TiO2 thin film. Sol-gel method is the best method which tends to be used due to its simplicity, good chemical homogeinity and high purity of the product. Titanium (IV) isopropoxide, isopropanol and acetic acid are the three different chemical which being used to make sol solution. The samples was then will annealed at three different temperature which are 400 °C, 500 °C and 600 °C to observed the phase composition of TiO2 added PEG thin film and pure TiO2 by using x-ray diffraction (XRD) analysis and the structural surface by using scanning electron microscope (SEM) analysis. The XRD analysis show the anatase phase present for the sample of pure TiO2 thin film and rutile phase present for the sample of TiO2 added PEG thin film. The micrograph of SEM show that with the addition of PEG at high temperature will give the analysis of flaky large cracked which is not separated to each other on the surface coating. Meanwhile, pure TiO2 give the result of irregular shape structure of the film.
