Full textAbstract:
Compression moulded NdFeB bonded magnets can advantageously replace the sintered version in applications that require specific shape and size. The maximum densities that can be obtained for ready-to-press commercial raw materials are close to 6.0 g/cm3. For large pieces, uniaxially pressed, densities should be limited to values as 5.0 g/cm3 due to the friction during compression. This paper investigate the effects of final density (ranging from 5.0 to 6.0 g/cm3) on the magnetic of compression moulded magnets. A ready-to-press Magnequench MQPB+ was used as raw material. Small cylindrical samples were produced by press and cure. Results are presented and discussed considering aspects related to relative densities. The magnetic properties are dependent of density, and coercivity decreases with deformation during compaction.

A new testing form was designed, in which the screens having gray scales and some solid blocks were included. The screens consist of gray scales from 0 to 100% of dot coverage, and the solid blocks also have coverage scales from 0 to 100%. Printing experiment was performed, and densities and dot coverage of specific places were measured and recorded. Based on the testing data, density or dot coverage undulation with printing impressions was indicated by curves. Furthermore analysis was taken. Dot gains in the same prints are not constant, which cause that saddle shape in prints. Some reasons from construction of press such as the gap of cylinder, swing of transferring roller and oscillation of oscillating rollers were brought out. Same values of ink presetting can not get the same printing quality in the ink zones which have the same graphic coverage. The traditional press has a long make-ready time in printing running, which can reduce the efficiency of press. Shaft-less technology of inking system is put forward to cut down the make-ready time and to decrease the power consumption. New algorithm research is necessary for ink zone presetting in order to get more precise ink feeding. Some research on the press construction is also important for the press having some inherent defects

On May 7, 1996 about 50 politicians were gathered together in the Parliament buildings in Cape Town negotiating the final details of South Africa's long-awaited democratic Constitution. There, too, were huddles of advisers, the long-suffering members of the administrative staff of the Constitutional Assembly, and members of the press who, generally absent from the process, had come to record the last moments. Behind the scenes the lay-out team was ready to put the last touches to the document and printers stood ready. Late that night, Cyril Ramaphosa, the Chairperson of the Constitutional Assembly, pleaded with the group in his characteristically ironic fashion: “I know it's late but just 20 minutes more, just 20 minutes – for our Constitution which is for the next 20 years, no, 50 years, 100 years, 200 years. …”

In 1995 I whined to Dave Henige about the difficulties involved in producing a 753-page volume of 383 pages of translated poetry (each including a work number, language of the original, source of the text, an historical introduction, and related text section) containing three orthographies, four languages, 947 footnotes, 241 pages of barely-arranged Arabic-script (but not all Arabic language) facsimiles, six maps, three glossaries, two works cited lists (published and unpublished), two appendices, and an index – all without a copy editor, and for a press demanding camera-ready copy from two novices an ocean apart who had access only to primitive email (remember CompuServe?) that would scramble poetic verse and jumble margins. When I finally took a breath, he smiled. Dave loves a challenge, and loves even more, passing one on. “Write about it,” he said. Suddenly I found myself signed up for the “Technical Problems in Preparing Text and Translations for Camera-Ready Copy” Historical Texts Panel at ASA's 1996 meetings. But that was not enough for Dave. He also expected an article, which I duly produced: “This Will (Not) Be Handled By the Press: Problems and Their Solution in Preparing Camera-Ready Copy for The Collected Works of Nana Asma'u, Daughter of Usman Dan Fodiyo 1793-1864” for History in Africa 25 (1998). In fact, it was Dave who rained on our anticipated title, “The Complete Works…,” dryly inquiring, “How can you be sure?” So it was “Collected Works…” instead.

The principle of inking system in sheet-feed printing press is introduced. Some tests on ink thickness are performed and the experiment results shows that in the traditional press, some inherent defects cause serious quality problems. The application of shaft-less drive technology to printing press is introduced and the drive principle of inking rollers of printing press and is explained. Synchronization control method of rollers is put forward, and the shaft-less technology is applied to the inking roller. Control system of shaft-less roller press is constructed for four color printing. Mechanical zero and electrical zero can be reset and corrected. Slight asynchrony is allowed between inking rollers and cylinders for normal printing, and the speed difference between them can eliminate a kind of printing troublesome of ghosting when needed. Analysis shows that with this technology, the functions of press are extended. Furthermore, the results of calculation indicated that when printing the special products, the make-ready time for inking is shorten about 50% and the power consumption is decreased about 19.8 to 21.5%, so the efficiency of machine can be increased by a big margin and the power cost can be cut down obviously.

Rajnarayan Chandavarkar—Fellow of Trinity College and Reader in History at the University of Cambridge—passed away on 23 April 2006. In addition to a rich legacy of books and articles that were published in his lifetime, he left behind an enormous amount of manuscript material, much of which was ready for publication. A selection of this material was published in his posthumous History, Culture and the Indian City (Cambridge University Press, 2009), but new manuscripts continue to come to light. His wife, Jennifer Davis, recently found this essay among his effects. There is good reason to believe that Raj felt it was ready for publication. Therefore, we publish this essay almost exactly as it appears in his typescript, only correcting typos and minor errors, and adding a map. The editors would like to thank David Washbrook and Jennifer Davis for proofing this article, Uttara Shahani and Binney Hare for researching and adapting the map, and Francoise Davis for the photograph of Raj.

Full textAbstract:
Purpose The purpose of this paper is to discuss the relationship dynamics between the executive office and the free press; and how these dynamics have been altered under the Trump administration. Donald Trump has questioned the validity and accuracy of claims, even going as far to call some organizations (CNN and The New York Times) “fake news.” The authors discuss the historically contentious relationship between the executive office and the free press as well as the ways in which Donald Trump has altered the dynamics of this relationship. Design/methodology/approach In this paper, the authors explore the role of the free press in American politics. The authors designed two classroom-ready activities by drawing on the best teaching practices advocated for in the C3 Framework. To elaborate, both activities allow students to research and analyze arguments made by Donald Trump and challenge false claims. This enables students to engage in the four dimensions of the Inquiry Arc in the C3 Framework. Findings The authors provide two activities that can be utilized in the high school social studies classroom to enable students to dissect American politicians’ messages. These two activities can be adapted and utilized to enable students to examine political candidate’s messages. By completing the steps of these two activities, students are better prepared to be critical consumers of political media messages and take civic action to challenge false claims. Originality/value Donald Trump has attempted to undermine the free press in the USA. He objects to stories that do not paint his administration in a positive light. This manuscript uses the media literacy position statement from NCSS and Ochoa-Becker’s framework for truth claims to explore Trump’s statements and claims.

Full textAbstract:
The study presents a new method, developed by the authors, for producing twist drills by extrusion using a three-slide forging press. The method consists in using two sectional dies with specially shaped impressions that allow the removal of a ready drill from the die without unscrewing. The study describes the main assumptions of the new method for twist drill extrusion, discussing benefits offered by this method when compared to the conventional process for producing twist drills by extrusion using a monolithic die. In order to verify the proposed solution, dies conforming to the assumptions of the new method were designed and executed. Experimental tests were conducted under laboratory conditions using a three-slide forging press. The model of the material used in the experiments was assigned the properties of Pb1 lead. As a result of the experiments, the theoretical assumptions of the new method could be examined and its practical application verified. Also, ideas for further research aimed at better understanding of the new technology for producing twist drills by extrusion are presented.

On the combination analog of the mussel ripple and leaf embrace, designed a new composite bottle cap consisting of the outer body, the inner lining washer, and the resin embrace, for multi-function, especially for better seal and ready open. According to the structural feature and the functional requirements of the cap, two fundamental components, the lining washer and the outer body, were abstracted into a plate and a cylinder with thin wall, respectively. Under the pressing force the elastic and plastic deformations of both were studied with Tresca’s yielding rule and the limitation of the plastic deformation was presented when the two components were assembled into a unit. For the production of this kind of bottle cap, the maximum value of the allowance press and the maximum pressing velocity were also provided.

Full textAbstract:
ECKA Granules Alumix 431D commercial grade, press ready, pre-alloyed aluminium-based powder containing 1.5 mass% of Acrawax C was used to study the effect of nitrogen linear flow on de-lubrication and sintering densification. In situ dimensional changes were controlled by dilatometry. Microstructural observations of sintered compacts were also performed. The results clearly showed the strong influence of nitrogen linear flow on de-lubrication, and thus on the sintering behaviour of the examined powder. High nitrogen linear flow is required to produce the desired sintered microstructure—characterised by residual porosity. In contrast, at low nitrogen velocity, the lubricant removal is not complete, which in turn significantly impedes densification.

Compression moulded rare earth magnets are used in many applications, and one of them is in electrical motors, which can operate at temperatures as high as 150 °C. In high temperatures, oxidation and phase transformations may affect magnetic properties. Another issue to be considered is polymer degradation. In this paper cylindrical samples of a commercial ready-to-press raw material (MQPB+, Molycorp-Magnequench) were pressed to densities close to 5.50 g/cm3. These samples were cured (low temperature heat treatment) and thermal aged at 200 °C for 72 hours, under dynamic air. Physical characteristics (weight, dimensions and densities) and magnetic properties were measured at room temperature in a TCH2020 hysteresigraph (Globalmag). Degradation of magnetic properties was observed, and oxidation seems to be the main reason.

Full textAbstract:
The aim of this article is to present the using of phraseological units in Georgian and French newspapers headlines. The role of the newspapers headlines is very important, because, to a certain extent, the understanding of the text depends on how the title presents the underlying text. Consequently, the journalists often use phraseological units to draw the attention of the readers. Phraseological units exist in the language as ready-made units and make newspapers very expressive because of their figurative nature. The analysis of press texts in both languages showed that the phraseological units are used for the purpose of text. We are going to try to show which type of phraseological units are used most of the time in the Georgian and French newspapers headlines.

With analytic applications in mind, in particular beyond endoscopy, we initiate the study of the elliptic part of the trace formula. Incorporating the approximate functional equation into the elliptic part, we control the analytic behavior of the volumes of tori that appear in the elliptic part. Furthermore, by carefully choosing the truncation parameter in the approximate functional equation, we smooth out the singularities of orbital integrals. Finally, by an application of Poisson summation we rewrite the elliptic part so that it is ready to be used in analytic applications, and in particular in beyond endoscopy. As a by product we also isolate the contributions of special representations as pointed out in [Beyond endoscopy, in Contributions to automorphic forms, geometry and number theory (Johns Hopkins University Press, Baltimore, MD, 2004), 611–697].

[This paper responds to “Monetary and Exchange Rate Policies for International Financial Stability: A Proposal,” by Ronald I. McKinnon, in this same issue.] For over ten years, Ronald McKinnon has advocated a new monetary system centered on fixed exchange rates between the Japanese yen, the German mark, and the U.S. dollar. His proposal has fallen on fertile soil because the dramatic volatility in exchange rates makes the financial press and the business community grasp for ready answers. McKinnon's scheme seems to solve the problem of currency instability and to judge from his presentation there are only merits and not one shortcoming. In fact, however, there is little theoretical or empirical basis for his standard. To support this criticism, I will first summarize several of McKinnon's key propositions and prescriptions and then review these in a critical spirit.

Artificial Intelligence (AI) is gradually changing every industry, including the Public Relations industry (Afzal, 2018). Skills associated with conducting research, creating content, evaluating campaigns, tracking issues and countless work processes are being automated with AI. We believe, although never fully replace public relations professionals but will increasingly assist us and possibly do a better job. We are developing PR Bot, a tool that help PR to create an instant press release using an AI (machine learning). Before we continue building the app, we need to know whether the PR practitioners will accept this technology or not. To find the results we conduct a descriptive research, using interview and polling survey, convenient sampling among the PR professional in Greater Jakarta area. We use Technology Acceptance Model to develop the questionnaire. According to the interview, we found that the knowledge and skill of using new technology of the respondents is very good. The survey shows the acceptance of the perceived ease of use and perceived usefulness of the PR Bot is high. The conclusion, the target market is ready to use the technology, they feel that this tech will help them in daily basis task. Based on this result, we will continue developing and using the insight from the respondents to build the feature of this application.

Full textAbstract:
These words introduced a collection entitledDeutsche Wehrlieder für das Königlich-Preussische Frei-Corps(German Military Songs for the Royal Prussian Volunteer Corps), that appeared in March 1813 immediately after Prussia declared war on France. It was not only in this songbook that the patriotic national mobilization for the struggle against Napoleonic rule was closely linked to the propagation of “valorous manliness” (wehrhafte Mannlichkeit). In the period of the Wars of Liberation between 1813 and 1815, the press and topical literature teemed with similar phrases and cultivated a veritable cult of manliness. A new breed of “patriotically”-minded, “combat-ready” men was needed if, as intended, a “people's army” of conscripts was to fight a successful “national war” against France. This phenomenon has generated scant interest in the extensive historical literature about the time between 1806 and 1815, which is considered as the birth period of the German national movement.

Full textAbstract:
The main aim of this paper is to show how ECAP influences the porosity distribution of PM aluminium alloys. The dimensional and morphological characteristics of investigated materials were measured individually for each pore. A commercial ready-to-press aluminium based powder (ECKA Alumix) was used as material to be investigated. After applying different compacting pressures (400 - 700 MPa), specimens were debinded in a ventilated furnace (Nabertherm) at 400 °C for 60 min. Sintering was carried out in a vacuum furnace at 610 °C for 30 min. The specimens were ECAPed for 1 pass. When severe plastic deformation is applied, the stress distribution in deformed specimens causes the powder particles to squeeze together to such an extent that the initially interconnected pores transform to small isolated pores, determining a given value of the dimensional characteristics. Consequently, ECAP influences the porosity distribution in terms of the involved severe shear deformation and therefore influences the pore morphology.

Full textAbstract:
The linkage of suicide and crisis was a prominent feature of Weimar Germany's cultural landscape. In films as different as Bertolt Brecht and Slatan Dudow'sKuhle Wampeor Walter Ruttmann'sBerlin: Symphony of a Big City, suicide appears as a reaction to the darker aspects of urban modernity: an individual's answer to capitalist exploitation or personal drama in an otherwise smoothly functioning metropolis. In a number of contemporary novels the possibility of a suicide is disturbingly present. In Vicki Baum'sGrand Hotel, one character asks himself, “My God, does everyone now have his tea cup of veronal ready?” Tales of suicide also surfaced in the tabloid press which presented them as human interest stories. Partisan papers supported their respective stances by tying individual actions to political narratives, a strategy pursued by both Nazis and Communists as well as liberal reformers. Even schools' reports on pupils who had taken their own lives and farewell notes themselves echoed a general feeling that suicide was a sign of the times.

This article describes features of phytoremediation. Phytoremediation involves planting beds of wetland vegetation and using them to treat or dewater several types of noxious effluents, including sewage sludge, leachates from landfills, and wastes from chemical plants and oil-drilling operations. According to a video produced by New England Waste Systems, more than 60 municipal wastewater treatment facilities in the United States are using reed beds to treat at least part of their sludge. The reed bed can handle only a certain amount of sludge at any one time. Occasionally, Lloyd’s bed has been overloaded, causing some of the green growth to die off, but with patience and light loading the next few times, the reeds have been able to bounce back. In effect, solar energy is replacing fossil fuels and electricity. The costs, environmental and otherwise, of generating electricity are avoided, and all those chemical additives are kept in their bottles. Proponents say the remaining solid material, when ready to be dug up and disposed of, is far cleaner than waste that has merely been put through a filter press.

Following Milton Babbitt's untimely death at the age of 94 (death at any age is untimely, since it unties the time dimension) in January 2011, I was interested in finding out more about his relationship, personal and music-theoretical, with the US information science community during and after the Eisenhower years. The musical avant-garde represented in parody by Babbitt and Cage as two poles of an antithesis sprang into life in the Cold War era at the same time as Scientology, MAD and Playboy magazine. Today the US doyen of priapism is ready to admit that even the best formula for a creative life has its natural limits. I wanted to ask Joseph Straus and Jerry Kohl what they thought of Babbitt's influence in the wider context of cognitive linguistics. In addition to positioning Babbitt as a significant influence on the Russian composer's serial music in the instructive Stravinsky's Late Music (Cambridge University Press, 2001), Joseph Straus is co-editor (with Stephen Dembski) of Babbitt's Words about Music. Jerome Kohl is a fellow Stockhausen enthusiast and distinguished former editor of Perspectives of New Music, a periodical set up in the 1960s to assert US authority in new musical theory and practice by an editorial board including Babbitt and graced by a logo in honour of serial music devised by Stravinsky himself.

Full textAbstract:
The paper deals with the influence of severe plastic deformation on the typical powder metallurgy (PM) microstructural characteristics, such as porosity, of a PM aluminum alloy. A commercial ready-to-press aluminum based powder was used as material to be investigated. After applying different compacting pressures (400, 500, 600 and 700 MPa), specimens were debinded in a ventilated furnace at 400 °C for 60 min. Sintering was carried out in a vacuum furnace at 610 °C for 30 min. The specimens were ECAPed for 1 pass. The dimensional and morphological porosity of investigated materials were measured individually for each pore. Results show that ECAP generates shearing stress breaking down the oxide film; this, coupled to particles deformation under local constraints, enables strong bonding and stability. Therefore, ECAP supports next progressive decreasing of pore size as well as strongly influences both dimensional and morphological porosity characteristics, considering that small pores evolve easily to a circular form.

Full textAbstract:
This study aims to identify how Arab press deals with issues of tolerance and ways of addressing the Other. The study traces this theme in some of the major Arab daily newspapers inside and outside the Arab world. These newspapers are: Al-Ahram, Al- Riyadh, Al-Sharq Al-Awsat, and Al-Hayat. The study argues that the media alone do not create the image or even attempt to change it. In fact, there are other institutions that strive to do this. In all societies, there are institutions that actually provide the raw material which is then used to form the desired stereotypical image of individuals, societies, countries, and institutions. The media then seize this material, forge it and integrate it with framed media packages that are then used as ready-made recipes to produce, alter or reinforce these stereotypes in which the Other is always an embedded element. The study recommends that Arab media need to develop awareness among Arab citizens through enhancing positive principles and values that contribute to the social cohesion of the society. They also need to stress the issue of identity and encourage an active role of individuals in issues of common social interest. They need to promote a culture of acceptance of the Other, however different that Other might be.

Full textAbstract:
The article analyzes the male daily and leisure activities among the Ukrainian workers, reflected in the press of the 1920–1930s. The objective of the article is to study the specifics of media representations of male daily and leisure activities and to determine the features of modeling the normative masculinity of a proletarian in the 1920s and 1930s. Research results. Based on the analysis, the conclusions are drawn about the normative masculinity of the Soviet proletarian of the 1920–1930s, reflected in Ukrainian newspapers and magazines. The Soviet construct of masculinity consisted of two models – ideal and real. According to the journalists of that time an exemplary proletarian was a physically strong man, certainly a Komsomol member or communist, capable of performing the labor, sports and / or military heroic acts for the sake of party and homeland. The propaganda of physical education and sport had military connotation, because sports organizations were entrusted with the task of preparing the men for a future war with the capitalist countries. Some forms of cultural recreation were popularized in the press: visits to work and other clubs, libraries, non-alcoholic picnics in nature etc. However the journalists of the 1920s and the early 1930s designed also another, more reliable model of the proletarian, through reflection of social reality and everyday context of working life. The daily and leisure activities formed the proletarian life style, which included alcohol abuse, primitive habits in everyday life, gambling, etc. Сonclusions. In the Ukrainian Soviet press of the 1920s, two versions of normative masculinity of the proletarian coexisted – official and popular. In the 1920s, a lot of critical materials appeared in the Ukrainian press regarding the life and leisure activities of proletarians. But in the 1930s, such reports almost disappeared from the newspapers, and embellishment of reality and mass dissemination of the ideal proletarian image, ready for labor exploits and defense of the fatherland from capitalist enemies, became a general tendency. Significance. In the modern media studies one of the key points is that media texts form social identity and subjectivity. The study of interconnections and interactions within the framework of the paradigm media – ideology – society is important and promising area, including the historical aspect.

"Influence of Pressure Extraction Systems on the Performance, Quality and Composition of Virgin Almond Oil and Defatted Flours." Foods 10, no. 5 (May 11, 2021): 1049. http://dx.doi.org/10.3390/foods10051049.
Full textAbstract:
Almond is the most cultivated nut throughout the world. The oil content of almonds in most varieties exceeds 50%, which encourages the oil extraction to be used in gastronomy or in the cosmetic industry. The preferred system to extract almond oil is by means of pressure, which leads to obtaining a virgin oil ready for consumption. In this work, almond oil has been obtained using two pressure systems: screw press (SP) and hydraulic press (HP). The performance of both methods, as well as their influence on quality and composition characteristics of the almond oils obtained are analyzed from both a physical-chemical and sensory point of view. From an industry perspective, the highest oil yield is obtained with the SP when it operates at temperatures of 100–150 °C. Regarding the quality and chemical composition, the oils obtained by HP showed better quality indices, as they are subjected to a less aggressive treatment without influence of temperature, but lower content in total sterols. Fatty acid pattern, characterized by the predominance of unsaturated fatty acids (>90%), was not affected by the pressing system. The different operational conditions tested did not greatly affect the performance or composition of the oils obtained, but sensory tests showed two clearly differentiated products, the oil obtained by HP and that obtained by SP, according to consumer preferences. The defatted almond flours obtained as a by-product of the oil extraction process are characterized by a high content in protein and fiber, and a higher content in fat when the flour is produced from the pressing cake of HP.

Full textAbstract:
This article describes the first survey of European science journalists working for general national print media and news agencies in 14 different countries of the European Union. The survey was carried out through the internet and calls for participation were sent to 208 journalists from 102 different media. Answers were received from 97 science journalists, a response rate of 46.6 percent. After the survey, interviews with 12 of the respondents were conducted. The main conclusion is that not only are science journalists becoming more dependent on scientific journals in their daily reporting, they are also spending a lot of time on the internet – 3.5 hours a day, on average – an activity that increases the concentration on breaking news and prevents them from going outside the newsroom to write more feature stories. In consequence, readers are receiving a distorted image of science as a series of ‘discoveries’ or ‘breakthroughs’, distant from the real daily world of scientists and the scientific process. This dependency on the internet, and on ‘ready-to-write’ press releases from scientific journals, is threatening science journalism, as professionals are controlled by the same embargoes, are using the same sources and visiting the same sites, no matter what country they are working in. This loss of information diversity is a consequence of the introduction of the internet in newsrooms, but also a result of the increasing media awareness of science sources.

Branding activities carried out to provide an image to the public about a brand. As one of the tertiary institutions in Sumatra that specializes in arts education, the Indonesian Institute of Art (ISI) Padangpanjang does not have a brand identity that is able to reach the public effectively. This has caused a lack of relationship between the ISI Padangpanjang and the public. To build a strong institutional identity that easily touches the public emotionally, gives a feeling of being closer so as to foster public trust in the institution, a mascot of ISI Padangpanjang has been designed. In the process, branding theory, as well as analysis of the vision of ISI Padangpanjang became the foundation in creating a mascot design. The results obtained are the creation of a mascot representing the ISI Padangpanjang named Si Kuaw. The Si Kuaw mascot design method is carried out through the design stages: research, thumbnails, roughs, comprehensive, and ready to press. As a media branding, the Si Kuaw mascot has been applied to various media, such as: motion graphics, art exhibition posters, new student acceptance brochures, pins, and mascots in the form of dolls.

Full textAbstract:
The nineteenth century was an era of enormous changes in garden design and garden practice. A wealth of new and exotic plants, located and shipped back by adventurous plant hunters from southern Europe and other, warmer continents, changed the look and character of the garden beyond recognition. The repeal of the glass tax and advances in iron and glass production initiated the craze of the glass house. “Bedding out” consequently became popular, a system in which delicate plants grown under glass could be planted straight outside in warmer months, producing instant colour and ending the frustrating months of bare beds during which gardeners waited for native perennials to bloom. And there were many other important technological advances to ease the lot of the Victorian gardener, such as the patenting of the first lawn mower in 1830 and improvements in tool design. Moreover, with huge advances in printing press technology and distribution, a slew of gardening magazines and gardening manuals sprang up to educate and aid the amateur gardener. The rise of the middle class, housed in suburban terraces and villas with small gardens front and back, produced a ready market for such texts.

The Sumatran Money Museum (MUS) in Medan, North Sumatra is one of the self-managed museums, with a collection of thematic and distinctive artifacts, namely the Sumatran currency! The official currency that was issued after independence in 1947-1949. This is among MUS's strengths. However, the problem that arises is that MUS has not yet maximally arranged aspects of visual communication such as consistency in implementing corporate identity, stationary, and graphic signaling (sign system), including the absence of graphic information (infographic) information on the history of the Sumatran currency. This study provides solutions to problem solving through designing a visual communication media based on identity (brand identity) and prioritizing informationfriendly principles, especially for young millennials. The problem in this study was answered by using the design method by following the stages of the graphic design process from Amy E. Arntson namely Research, Thumbnails; Roughs, Comprehensives and Ready for Press. The solution obtained from this research is to design a corporate identity service. Consists of the logo, stationary, merchandise and graphic information of the museum. As a first step in building the MUS brand identity.

Full textAbstract:
The article examines the daily life of the Ukrainian officers (elders) imprisoned in the Camp of Cassino (Italy) in 1919 – the first half of 1920. It deals with illustrated materials published by the camp editions. The community of Prisoner Ukrainian officers has a special place in the history of Ukrainian captivity in Italy. It is determined by the level of national consciousness of its members, and those significant achievements in the field of culture and education that were made due to their morality and active citizenship. Living in the conditions of camp and being almost completely isolated from the national life of Ukraine, the Prisoner Ukrainian elders managed to organize the work of schools and educational courses. They organized a choir, orchestra and amateur theater. They celebrated national Ukrainian holidays as well. Most of the Prisoner Ukrainian elders were ready to give their assistance to the UNR in its fight against the Bolshevik Russia by joining the national army. The camp press vividly reflected the national self-consciousness of the Prisoner Ukrainian elders. It contributed to the unity of camp prisoners and helped them to overcome strength to overcome the difficulties of everyday life. The production of the camp editions, such as «The Prisoner» magazine and its satirical-humorous appendix «Lazaroni», faced a lot of problems. The editions were produced manually in the amount of one (or several) copies of each issue. Nevertheless the camp editions met the prisoners’ demand for information effectively. They also performed an extremely important functions of mobilizing and educating the prisoners.The author emphasizes that the camp press was highly important not just for the prisoners, but for the whole Ukrainian community in Cassino. It contributed significantly to preserving the Ukrainian national identity and supported the idea of Ukraine’s independence.

The article is devoted to the problem of public solidarity through volunteer activities during the fight against the pandemic. At the beginning of the article, the phenomenon of volunteerism is considered as a new social institution that is ready to consolidate society, contribute to solving global problems and meet the challenges of our time. Further, the concept of solidarity in the works of outstanding scientists is considered, which leads to the conclusion that solidarity is the most important component of civil society. The empirical study uses inductive content analysis using marker words from nine of the most popular Russian press publications from March to August 2020, which describes the types of volunteer activities during the pandemic, provides statistics across the country, reviews the results of work, and identifies the problems faced by both volunteers and citizens in need of support. A detailed analysis of solidarity in the framework of the activities of pandemic volunteers was conducted using the example of the all-Russian volunteer action #WeAreTogether. In conclusion, the results of the study allow us to state the fact that the fight against the pandemic has become the most important factor in uniting the citizens of Russia, where public solidarity is one of the main components of the development of civil society.

Full textAbstract:
Abstract Traditional static publication formats make visualization, exploration, and sharing of massive phylogenetic trees difficult. A phylogenetic study often involves hundreds of taxa, and the resulting tree has to be split across multiple journal pages, or be shrunk onto one, which jeopardizes legibility. Furthermore, additional data layers, such as species-specific information or time calibrations are often displayed in separate figures, making the entire picture difficult for readers to grasp. Web-based technologies, such as the Data Driven Document (D3) JavaScript library, were created to overcome such challenges by allowing interactive displays of complex data sets. The new phylogeny.IO web server (https://phylogeny.io) overcomes this issue by allowing users to easily import, annotate, and share interactive phylogenetic trees. It allows a range of static (e.g. such as shapes and colors) and dynamic (e.g. pop-up text and images) annotations. Annotated trees can be saved on the server for subsequent modification or they may be shared as IFrame HTML objects, easily embeddable in any web page. The principal goal of phylogeny.IO is not to produce publication-ready figures, but rather to provide a simple and intuitive annotation interface that allows easy and rapid sharing of figures in blogs, lecture notes, press releases, etc.

Full textAbstract:
AbstractThis article examines a much cited but little understood aspect of the Latin American intellectual and cultural ferment of the 1910s and 1920s: the frequency with which intellectuals from the southeastern Brazilian state of São Paulo referred to developments in post Sáenz Peña Argentina, and to a lesser extent in Uruguay and Chile. In books, pamphlets, speeches, and the pages of a vibrant periodical press—all key sources for this article—São Paulo intellectuals extolled developments in the Southern Cone, holding them out for imitation, especially in their home state. News of such developments reached São Paulo through varied sources, including the writings of foreign travelers, which reached intellectuals and their publics through different means. Turning from circuits and sources to motives and meanings, the Argentine allusion conveyed aspects of how these intellectuals were thinking about their own society. The sense that São Paulo, in particular, might be “ready” for reform tending toward democratization, as had taken place in Argentina, Uruguay, and Chile, was accompanied by a belief in the difference of their southeastern state from other Brazilian states and its affinities with climactically temperate and racially “white” Spanish America. While these imagined affinities were soon forgotten, that sense of difference—among other legacies of this crucial period—would remain.

Full textAbstract:
The article examines the image of radical Islamists, which was created in the publications of the largest domestic periodicals during the military operations in Dagestan in August–September 1999. The author analyses front-line reports and interviews with high-ranking military leaders published in such central newspapers and magazines as Nezavisimaya gazeta, Trud, Izvestiya, Kommersant, Echo planety, Novoe vremya and some others. Among the sources, there are both serious analytical broadsheets and tabloids. The author also pays attention to the regional press, for example, the Yaroslavl periodicals Karavan-Ros and Yaroslavskie novosti. These publications delivered valuable information on the ideology of the enemy, their weapons and equipment, and the war crimes they committed, and also reflected the attitude to the militants of the Russian soldiers and policemen who opposed them. The detachments of militants who opposed the federal forces and the Dagestani law enforcement officers appeared in these reports as cruel religious fanatics, intolerant of the bearers of any other ideology, ready to impose it on other people by force. At the same time, following military and law enforcement officials, Russian journalists were forced to recognize high combat qualities of the enemy, their perseverance and steadfastness in battle. Most of the pieces mentioned the fact that the rebels possessed a large number of modern weapons, both domestic and foreign-made, and also said that they had developed professionally competent in-depth defense. The author draws a conclusion about the antipathy of Russian reporters to the rebel combat units and identifies the reasons for the change in the attitude of the media towards them in comparison with the First Chechen War of 1994–96. In those years, journalists condemned military actions of the federal forces in the Caucasus, but in 1999 they supported the operation in Dagestan and considered Islamic radicals as ordinary bandits.

The subject of this study is relationship of Alexey Remizov with his readers from the professional literary community that draws from the materials of the author’s scrapbook Foreign Censorship — unknown artifact created in 1923–1931. The album as a product of the literary “everyday life” (“byt”) reflects the process of Remizov’s selfreflection prompted by various instances of editing and criticism of his works in the emigrant press. The author of this article explains the meaning that Remizov associated with censorship under the conditions of emigration and highlights the hidden plots of Remizov’s biography connected with the publication of his censored works. The collection of materials in the scrapbook reveals Remizov’s rejection of the ready patterns of the literary norm and stereotypes that affected the perception of his work by editors. Analysis of the scrapbook’s documents has allowed disclose the reasons for imposing editorial restrictions on Remizov. The author specifically focuses on the critical reviews selected by Remizov for his scrapbooks demonstrating the discrepancy between Remizov’s own “horizon of expectation” and that of his critics. The article is followed by the publication of the hitherto unpublished archival materials, a welcome addition to Remizov’s biography that reveals his place in the Russian émigré literary scene.

Full textAbstract:
Wax apple (Syzygium samarangense) is an important tropical fruit tree cultivated in Southeast Asian. It produces red pear-like shape fruits. The fruit flesh is considered high in antioxidants, phenolics, and flavonoids that have a potential to contribute to the human healthy diet, and was proved to have anti-inflammatory and antimicrobial characteristics. To allow year-round marketing of high quality wax apple fruit, growers always perform shading to inhibit new flushes so as to repress vegetative growth and promote reproductive growth. To investigate the effect of shading on carbohydrates, wax apple trees were shaded with sun shade nets under field conditions. The effects of shading on shoot growth were studied and leaf carbohydrate levels of the trees were determined. The results showed that shading inhibit the the growth of the terminal shoots and promoted bud dormancy. Shading also reduced total soluble sugar, sucrose, glucose, fructose, and starch levels of leaves. The results suggested that shading reduced carbohydrate accumulation and repressed vegetative growth.

Full textAbstract:
One of the great challenges that apple producers face is to substantially improve the quality of fruit, including after harvest. A balanced and timely supply of calcium (Ca) during growth and in the post-harvest stage is considered a technique that could improve shelf life and fruit quality; thus calcium plays a key role during post-harvest, with calcium carbonate and calcium sulphate being an alternative of foliar spraying. The study was carried out on ‘Top Red’ and ‘Golden Delicious’ apple cultivars, in a randomized complete block design with 13 treatments (referring to different commercial presentations of calcium) and 6 repetitions; 8 foliar sprays were applied weekly, from June 22 until harvest; ‘Top Red’ (151 days after full flowering, DDCF) and ‘Golden Delicious’ (145 DDCF) fruit were evaluated in regard with fruit traits (diameter, weight and colour) and maturity (pulp firmness, total soluble solids, titratable acidity and sugar acidity ratio). In ‘Top Red’ cv., calcium carbonate presented the best results, with intermediate to high quality apple fruit, while for cv. ‘Golden Delicious’ the best results were obtained with calcium sulphate, which increased fruits’ diameter, weight, colour and titratable acidity. Even more, of the products evaluated, CaCO3 and CaSO4 had the lowest costs, and can be considered as good alternatives of foliar calcium supplement applied in order to preserve the quality of the apple during post-harvest.

Full textAbstract:
A rapid micropropagation protocol was designed to produce Calamintha sylvatica plantlets by using nodal segments as explants for the shoot formation. 6-BA favored the highest shoot formation and biomass yield, whilst kinetin was found superior for the highest shoot length (38.97 ± 2.85 mm) and node numbers (2.89 ± 0.63). Rosmarinic acid was detected as major phenolic acid, ranging from 7.59 mg/100 g to 81.44 mg/100 g. Hexane extracts from natural and in vitro propagated plantlets showed activity only against Staphylococcus aureus ATCC 25923 with MIC values at 6.25 and 3.33 m/mL, respectively while in the latter case, extracts from natural plantlets exerted higher cytotoxic activity than those of micropropagated ones (IC50 values were 83 µg/mL and 98 µg/mL on HeLa cells, respectively). C. sylvatica showed high micropropagation performance and produced remarkable amount of rosmarinic acid in vitro as well as antimicrobial and cytotoxic effect.

Full textAbstract:
Nitrogen (N) is an essential mineral nutrient for plant growth and development. Wild soybean (Glycine soja), which has many superior traits, is an important germplasm resource and is also an excellent experimental material for researching the mechanisms of low-N tolerance. In this study, the physiological differences between common wild soybean (W1) and low-N tolerant wild soybean (W2) among growth characteristics, photosynthetic carbon (C) metabolism, N metabolism and C-N metabolic-coupling relationship were investigated, and the mechanism of low-N tolerance of wild soybean was explained at three different levels of low-N stress. Both W1 and W2 showed some resistance to low-level N stress. However, W2 could withstand the damage by increasing the root length and root–shoot ratio under high-level stress conditions. Moreover, when resisting low-N stress, W2 maintained a stable photosynthetic rate and coordinated ion balance to maintain required nutrient levels. W2 also tolerated low N by coordinating the C-N metabolic balance through the accumulation of soluble sugars to provide energy and C skeletons for N metabolism and through enhanced N metabolic enzyme activities and soluble protein accumulation levels to supply the enzyme proteins and photosynthetic pigments for C metabolism. The current results provide a physiological methodology and theoretical basis for protecting wild soybean germplasm resources and improving cultivated soybean.

Citrus canker is a quarantined disease, severely harming citrus plants. Soil beneficial arbuscular mycorrhizal fungi (AMF) can provide a biological control pathway to resist pathogens. This work was to test changes of signal substances including hydrogen peroxide (H2O2), nitric oxide (NO), calmodulin (CaM), salicylic acid (SA) and jasmonic acid (JA) and the pathogen defense gene expression in roots of AMF (Paraglomus occultum) and non-AMF trifoliate orange (Poncirus trifoliata) seedlings after infected by a expressions citrus canker pathogen (Xanthomonas axonopodis pv. Citri, Xac). AMF inoculation significantly improved plant height, stem diameter and leaf number. Xac infection dramatically decreased root H2O2, NO, and SA levels, but increased root CaM and JA concentrations in non-AMF seedlings. There were higher H2O2 and CaM levels and lower JA levels in Xac-infected seedlings than in non-Xac-infected seedlings under mycorrhization. Under non-Xac infection, mycorrhizal treatment reduced root H2O2, NO, and SA but increased CaM and JA levels. However, under Xac infection, mycorrhizal inoculation distinctly accelerated root H2O2, NO, CaM, and SA accumulation, accompanied with up-regulated expression levels of root PtEPS1 (enhance pseudomonas susceptibility 1) and PtPR4 (pathogenesis related gene 4), indicating that Xac stimulated mycorrhizal roles in enhancing resistance of citrus canker. Such results imply that citrus plants with pre-inoculated AMF had stronger resistance to Xac infection through increasing signal substrate accumulation and pathogen defense gene expressions.

Full textAbstract:
The first risk posed by heavy metal pollution in an ecosystem is metal accumulation in the biomass of growing plants, which has harmful effects on human health. Natural-based nanoparticles are efficient in remediating environmental pollutants because they have a high surface/volume ratio, high chemical activity and produce no harmful side-products. The present study investigates the capacity of natural-based nano-porous adsorbents for reducing the availability of heavy metals to annual alfalfa (Medicago scutellata L.) roots and keeps them in soil. In a factorial experiment based on a randomized design (with four replications), three nano-adsorbents (nano-activated carbon, natural nano-zeolite and modified nano-zeolite) and two heavy metals (lead and cadmium) have been tested. The results demonstrated that applying the highest rate of activated carbon and modified nano-zeolite reduced shoot Pb content by 34% and 33.2%, and shoot Cd content by 35.5% and 46.7%, respectively, compared with the adsorbent-free control.
