The beginning of the article briefly outlines the history of Jindřichův Hradec from its foundation through its development in the 15th century and especially in the 16th century, until the 19th century, when the Landfras printing works functioned in the town. Afterwards, the article focuses on the Landfras family of printers and its work in Jindřichův Hradec. It deals with the founder of the printing works, Josef Jan Landfras (1869–1840), as well as with his family background and his public activities. Most attention is devoted to his successor, Alois Landfras (1797–1875), who became one of the most remarkable figures in the history of Jindřichův Hradec, because he was very actively involved in social events in the town. From 1841, he was a member of the town council; ten years later, he was elected mayor and remained in the position for ten years. His private and family life is marginally mentioned as well. The last member of the family active in the 19th century was Vilém Antonín Landfras (1830–1902), who was also a member of the town council. Thanks to him, the weekly Ohlas od Nežárky [Echoes from the River Nežárka] began to be published in the town in 1871. The article further mentions his important role in the organisation of the social entertainment of burghers and his family life. The end of the paper is devoted to his son, Vilém Bohumil Landfras (1865–1931), whose work falls into the first third of the 20th century.

Full textAbstract:
AbstractElizabeth Pickering took over Robert Redman's press when he died in 1540, thus becoming the first woman known to print books in England. Her books tell us simply that she was Redman's widow. Wills and other legal documents in the London archives permit us to know much more. The documents examined here illuminate aspects of her personal life, but also reveal connections between a group of law-printers and lawyers that appear to have influenced the printing of law books in Tudor London. The first part of the essay traces this microhistory of family and community relations. The second half examines the books Elizabeth Pickering published.

Full textAbstract:
Three-dimensional printing with cement-based materials is a promising manufacturing technique for civil engineering applications that already allows for the design and the construction of complex and highly customized structures using a layer-by-layer deposition approach. The extrusion mechanism is one of the most expensive parts of the 3D printer. Also, for low-scale 3D printers, based on the shape of the extruder and the geometry limitation of the mixing blade, the 3D mixture is often limited to a narrow range of materials due to the risk of layer splitting or blockage. Therefore, there is a need to develop affordable and feasible alternatives to the current design–fabrication–application approach of 3D printers. In this paper, various newly designed mixtures of fiber-reinforced mortars that can be 3D printed using only a commercially available screw pump are analyzed based on their fresh properties and mechanical characteristics. The results, in terms of extrudability, buildability, flowability, and flexural and compressive strengths, highlight the potential of using this technology for constructing complex structures with high strength and durability. Also, the reduced facility requirements of this approach enable 3D printing to be made more available for civil engineering applications. With further innovations to come in the future, this method and these mixtures can be extended for the sustainable and economically feasible printing of single-family housing units.

Full textAbstract:
This article focuses on the history of the Rodez printing firm in provincial France from 1624 to 1820 (although the firm ran until 1984). In contrast to the world of clandestine printing and bookselling, very little is known about the lives of ordinary sedentary printers in ancien-régime France. The paper is organized in three parts and considers the following issues. How did the firm operate, who worked in it, what training was required, and what was produced? How did this change over time? Secondly, this was a family firm, so we may ask how was it kept in the family, and how did the family fare as it made a living out of printing? Here we have an insight into the history of an artisan family over nearly 200 years, the ascension of an artisanal family to the level of respectable bourgeoisie. The third area considered is the possible contribution to understanding the cultural world of a provincial town. The firm printed and sold books, and account books and order books give us further information, though of a fragmentary nature. From this it is possible to raise questions about recent research on the starkly contrasting world of Enlightenment bestsellers.

Full textAbstract:
Abstract This article examines the lost production of a sixteenth-century Parisian family of printers, the Bonfons. This family, who specialized mainly in medieval vernacular romances, was chosen because the survival rate of their publications is relatively low and the number of lost editions high. Such study goes beyond the strict framework of bibliometry to raise two questions: do bibliographies really reflect what was published at that time? And, as a corollary, do survival rates distort our perception of early-modern book production? Previous research on the Bonfons’s production is complemented by an outstanding source that has never been investigated in this context: the archives of the Commission of the Index of Prohibited Books of Antwerp (printed in 1570). In this light, the number of books printed for or by Jean Bonfons and his widow should be revised to almost 200 editions, with an average loss rate of around 40 per cent.

Full textAbstract:
In recent years, 2D materials have been implemented in several applications due to their unique and unprecedented properties. Several examples can be named, from the very first, graphene, to transition-metal dichalcogenides (TMDs, e.g., MoS2), two-dimensional inorganic compounds (MXenes), hexagonal boron nitride (h-BN), or black phosphorus (BP). On the other hand, the accessible and low-cost 3D printers and design software converted the 3D printing methods into affordable fabrication tools worldwide. The implementation of this technique for the preparation of new composites based on 2D materials provides an excellent platform for next-generation technologies. This review focuses on the recent advances of 3D printing of the 2D materials family and its applications; the newly created printed materials demonstrated significant advances in sensors, biomedical, and electrical applications.

Full textAbstract:
The microfluidics field is at a critical crossroads. The vast majority of microfluidic devices are presently manufactured using micromolding processes that work very well for a reduced set of biocompatible materials, but the time, cost, and design constraints of micromolding hinder the commercialization of many devices. As a result, the dissemination of microfluidic technology—and its impact on society—is in jeopardy. Digital manufacturing (DM) refers to a family of computer-centered processes that integrate digital three-dimensional (3D) designs, automated (additive or subtractive) fabrication, and device testing in order to increase fabrication efficiency. Importantly, DM enables the inexpensive realization of 3D designs that are impossible or very difficult to mold. The adoption of DM by microfluidic engineers has been slow, likely due to concerns over the resolution of the printers and the biocompatibility of the resins. In this article, we review and discuss the various printer types, resolution, biocompatibility issues, DM microfluidic designs, and the bright future ahead for this promising, fertile field.

Full textAbstract:
AbstractDespite the increased interest in all aspects of the Radical Reformation we are still in need of a bibliography of David Joris which might satisfy reasonable requirements. A. van der Linde's book, which presented itself as such over a century ago, is imprecise and not unnaturally entirely out of date. A new version would thus fulfil an obvious need. The reasons for which it has not yet been undertaken must be sought in the complication created by the fact that the hundreds of writings all appeared without an imprint. The dates, if indeed any are given, generally apply to the composition of the text and only coincide exceptionally with the often considerably later year of publication. All we can conclude from historical sources is that a number of his tracts were published in Deventer in about 1540 by Albert Pafraet and Dirk (II) van den Borne. In order to determine who dared to work for the arch-heretic (or, after his death, for later followers of his teaching) it is impossible to avoid a bibliographical analysis. In this manner we find the names of various of his printers and, from the years of their activity, we can deduce sufficient indications to date the publication of the writings within certain limits. This investigation shows that the first were indeed printed in Deventer, the very earliest being a treatise which has so far been ascribed to the Anabaptist Bernhard Rothmann. Thereafter David Joris gave orders for his works to be printed alternately in Antwerp, to Adriaen van Berghen, and in Deventer. After he had left for Basel he briefly applied to the services of two printers in the German-speaking area until he discovered a permanent supplier in the future university printer Ludwig Dietz in Rostock. The sectarian's death and his posthumous execution in 1559 were succeeded by a few decades of silence in the camp of his followers. In 1584, however, an edition of the Wonderboeck, entirely revised by the author, appeared and was soon followed by a series of other publications. Much previously unpublished work proved to have remained in the possession of David Joris's family. The printer, as he himself was later to admit, was Dirk Mullem in Rotterdam. When his activities came to an end in the last years of the century, other publishers took over the task.

En se basant sur l’histoire des Bradfords, l’une des plus grandes familles d’imprimeurs de l’histoire américaine, ce mémoire étudie la relation entre l’imprimé, les imprimeurs, et divers discours sur la liberté au cours du « long » 18e siècle. Il retrace la transition entre une ère de la « liberté de parole, » née des débats sur la liberté de presse et d’expression de la période coloniale, et une ère de la « parole de la liberté, » née au cours de la Révolution et entretenue sous la jeune république. Cette transition fut le produit de la transformation du discours des contemporains sur la liberté, mais s’effectua également en lien avec la transformation du milieu de l’imprimerie et de la culture de l’imprimé. Selon les circonstances politiques, sociales, économiques et culturelles particulières des périodes coloniale, révolutionnaire, et républicaine, l’imprimé et les imprimeurs américains furent appelés à disséminer et à contribuer au discours sur la liberté. Ils établirent ainsi une forte association entre l’imprimé et la liberté dans la culture de l’imprimé du 18e siècle, qui était destinée à être transmise aux siècles suivants.
Mots-Based on the family history of the Bradfords, one of America’s most celebrated printing dynasties, this thesis studies the interplay between print, printers, and various discourses on freedom during of the long 18th century and through the colonial, revolutionary, and early republican periods. It traces the transition between an era of the “speech of freedom,” born out of the colonial debates on the freedom of speech and press, and an era of the “freedom of speech,” born in the course of the Revolution and upheld during the early republic. This transition resulted from the transformation of the contemporaries’ discourse on liberty, but also had to do with the transformation of the printing trade and print culture. As a result of the political, social, economic, and cultural circumstances of the colonial, revolutionary, and early republican periods, American print and printers were led to disseminate and to contribute to the discourse on liberty. They thus established a strong association between print and freedom in the 18th-century print culture, an association which was destined to be transmitted to the following centuries.

Full textAbstract:
The printer and bookseller John Evans was, in the last decade of the eighteenth century, seemingly prolonging the lifespan of the type of publication that had hitherto typified the Aldermary Churchyard press and which it was abandoning in search of ‘respectability’. The place of business Evans established for his work, and which was retained by his family for a further forty-five years, was originally John Marshall’s, and what seems to have been his ‘big break’ came courtesy of Marshall when he fell out of favour with the patrons of the Cheap Repository Tracts. Nevertheless, Evans had a distinct career. Stretching into the 1800s, he was arguably the last printer of the traditional ‘penny history’ in the capital, a text and illustrative tradition that dated back at least to the printers and publishers of the mid-seventeenth century; he was a major link in the production of broadside ballads and slip songs between Marshall and the later printers Pitts and Catnach; and, as this chapter will show, he was a significant and heretofore underappreciated printer of street literature specifically for children.

Full textAbstract:
The widespread presence of the chapbook in Scotland (not to be confused with the Scottish chapbook) over the later decades of the eighteenth century (thus covering the period of its highest production) is subjected to a number of detailed considerations. The production of such material was dominated by a relatively few firms, and the greatest number of chapbooks themselves emanated at this period from Glasgow, followed by Edinburgh. The activities of the printers and publishers John Morren, Edinburgh, and the Robertson family, Glasgow, are given particular attention. Some chapbook publishers, as with James Chalmers of Aberdeen, evidently regarded their production as a small but integral part of their broader printing activities, while for others it came close to a monopoly.

Early modern and Enlightenment children travelled. They toured, emigrated, visited family, or fled persecution. Silvia Cole, the Dutch-English granddaughter of a Huguenot, moved to London. An Austrian ambassador’s daughter read English children’s books. Colonial civil servants and military officers fathered children while posted abroad, sometimes with local women. Teachers, female and male, also travelled, whether as religious, political, or economic migrants. Writing masters travelled to the American colonies. The French Revolution spread educators across Europe. Booksellers and printers published in more than one language and advertised to colonial markets. Drawing on paratexts, life writing, manuscripts, ephemera, and marginalia, this chapter seeks commonalities of reading experiences among children living abroad or in the care of foreign teachers, exploring how booksellers catered to both groups.

Abstract During his career as a provincial tradesman, Benjamin Franklin built a loosely structured network of fellow printers that spanned the colonies. Most of his associates had little of his ability for using journalistic artifice, and none attained anything close to his prestige, but several did hold local offices and the majority were capable publishers. They were typically his former employees and often became postmasters through his appointment. He shipped them Poor Richard almanacs and shop supplies and periodically advised them on financial and political matters. Some of his business relationships with printers were short-lived–such as those he established in attempts to start a German-language paper in Pennsylvania. Others—like his efforts to help his troublesome nephew Benjamin Mecom-involved intermittent attention to family duties.

Beyond the family, other collectivities also played a role in the production of written works that endured across generations. For literary and learned works, these other collectivities included: households (with their servants, secretaries, disciples, and collaborators in addition to family members); networks of clients, patrons, and friends; salons; courtly circles; institutions such as universities, humanist colleges, and printers’ workshops; religious communities ranging from monastic orders to Jesuits to Protestant churches. They had complex and varying relationships to families. Some overlapped with families or were supplementary extensions of them—especially households, governed by the family head. But some of these other collectivities were in competition with families for loyalty or offered an alternative to them. Moreover, literary and learned legacies could reach beyond the family to benefit broader communities.

Abstract In view of the uniquely complex development of James Joyce’s literary texts in notebooks, manuscripts, and typescripts, along with the author’s practice of composing extensively on the printers’ galleys, the study and appreciation of his art calls for an exacting examination of the written and printed materials involved at every stage. Voluminous materials of this kind have been dispersed throughout libraries and collections in Ireland, Britain, and the USA. Many of Joyce’s papers are now held at the Lockwood Memorial Library of the State University of New York at Buffalo, together with the Joyce family portraits.

This chapter unravels motherhood from idealized notions of the Jewish family and stereotypes of the Jewish mother and presents a complex, nuanced, and robust perspective on motherhood in the Jewish cultural imagination. It emphasizes the variety of identities held by mothers and the vast array of cultural and social patterns that characterizations of mothers reflect. It also shows how Jews used motherhood across time and place as a way to construct and comprehend their culture. The chapter refers to writers, activists, rabbis, artists, printers, and poets who have projected, created, engaged, and contested Jewish culture by relying on the trope of the Jewish mother. It goes on to explain how Jews break away from biological conceptions of motherhood.

This chapter reveals the complex afterlives of Peninsular War memoirs, many of which outlived their authors and continued to be published and re-published in different formats over the long nineteenth century. It considers the many different groups of people involved behind the scenes in the production of a Napoleonic military memoir: family members, especially women; editors; publishers; indexers; printers; illustrators; archivists; lawyers; even luxury booksellers. It shows in detail the alterations that were made to veterans’ autobiographies over time, from omitting or adding sections of text to changing the title, inserting portraits of the author, or commissioning artist’s impressions of his battles. Along the way, some war memoirs underwent an almost total transformation, becoming dry family biographies, ‘boy’s own’ adventure stories, regimental histories, consumer objects, or, in the decades before the First World War in Britain and France, tools for national military education, targeted to children.

This chapter looks at the medium of printed books that was introduced into Jewish culture soon after its emergence in the mid-fifteenth century. It discusses the arrival of the presses that were run by different members of the Jewish Soncino family in Italy and elsewhere at the beginning of the 1480s, wherein a wide variety of genres appeared in print. It also describes the Soncino editions that were distinguished among printers by the accuracy and beauty of their typefaces. The chapter mentions the early printed book that was seen as a radical innovation in the age of complex cultural transformations both within and outside Jewish society. It recounts how the 'knowledge explosion' that was spurred by the rise of the printing press was a key factor in the formation of early modern Jewish cultural history.

Chapter 4, ‘The mystery and school house of nature: bibliography and the works of Thomas Willis’, explains that there is no published bibliography of the works of Thomas Willis. Copies known to Willis’s contemporaries, and those which remained in the family until the nineteenth century are identified. The process of imposition, printing, stop press alteration, folding and distribution of sheets, and binding are described. From this follows discussion of bibliographical description relating to separate editions and issues, and the state of individual leaves. The bibliographical method used in the book is explained: classification, title page(s), collation, type, contents, headlines, catchwords, frontispiece, portrait, printers’ ornaments, decorated initials, plates, and the copy used for detailed description. The chapter concludes with a short title list of 103 copies containing various combinations of the fourteen treatises printed in Latin, English, or Dutch across the period of interest (1659–1721). {143 words}

Multiple factors affect the decisions of selecting the appropriate components to share in product family design. Some of the challenges that the designers face are maintaining uniqueness and the desired performance in each variant while taking advantage of a common structure. In this paper, the sharing decision making process is analyzed for the case when a firm knows a priori that some of the components contain sensitive information that could be exposed to the user, third-party manufacturers, or undesired agents; thence, it is important to enclose it and protect it. Two important aspects to consider are defining the architecture of the product while protecting the sensitive information. This paper proposes tools to help the designers to identify components that are candidates for sharing among the family and finds the most desirable component arrangement that facilitates sharing while protecting the sensitive information that has been previously identified. The proposed framework is applied to three printers in which the architecture used for the ink cartridges and printheads are significantly different. Third-party manufacturers and remanufacturers offer their own alternatives for these subsystems (ink cartridges and printheads) since the customer for printer supplies is always looking for a cheaper alternative; meanwhile, the OEMs attempt to secure their products and retain their customers with original supplies. Having identified the sensitive components for each printer, the optimal clustering strategy is found, as well as the set of components that are candidates for sharing, according to their connectivity and the security considerations.

Abstract. The FFF process is one of the most widely used additive manufacturing processes for shaping thermoplastic polymers. The recent development of industrial printers equipped with high-temperature ovens has made it possible to print high-performance thermoplastics from the PAEK family for applications in the aerospace, medical and other industries. Numerous studies have shown that thermal history is a key factor to improve the mechanical properties of printed parts. Nevertheless, the uniformity of mechanical properties of printed parts is generally poor and highly dependent on the homogeneity of the thermal oven used, which, to our knowledge, has never been properly characterized. For semi-crystalline polymers, the thermal driven crystallization process is also a key factor in adhesion. However, the coupling between phase transformation and heat transfer is often neglected in numerical modelling and its influence has not yet been clearly demonstrated. In this work, we will carry out a preliminary characterization of the printer by measuring air velocity and temperature gradients over the whole printing zone. Secondly, the comparison between simulation and experimental measurements will show the importance of correctly predicting crystallization kinetics to obtain more accurate predictions.

Full textAbstract:
The development of high-temperature fused filament fabrication (FFF) 3D printers has enabled the additive manufacturing (AM) of polymers and composites with relatively high thermomechanical properties. Among them is polyetherketoneketone (PEKK) reinforced with short carbon fibers (CF-PEKK). PEKK is a high-performance thermoplastic that belongs to the polyaryletherketone (PAEK) polymer family with excellent mechanical properties. In particular, it offers a glass transition temperature of ~140°C, a relatively high modulus that can be readily enhanced by carbon fiber addition, and specific strength comparable to aluminum alloys. Therefore, there is a growing interest in using CF-PEKK to replace metal parts. Low dimensional accuracy and resolution, high porosity, and poor inter-layer strength [1-3] have limited FFF parts to rapid prototyping and non-structural applications. This paper aims to investigate extrusion rate, a printing parameter, and post-annealing as a potential solution to reducing porosity and enhancing inter-layer strength in CF-PEKK printed parts. A 5% increase in the theoretical extrusion multiplier (EM) resulted in a 1.6% reduction of void content accompanied by a 30% improvement in the inter-layer tensile strength of CFPEKK coupons. The impacts of extrusion rate and post-annealing (in a salt-packed container) on the printing quality of CF-PEKK parts are also determined. No significant structural or dimensional changes were detected with the higher extrusion rate or annealing in salt. This paper provides a new understanding of mechanical properties, processing, printability of CF-PEKK, and their AM challenges.

This paper investigates the thermal and radiation performance of 3D-printed ULTEM materials following ASTM standard D638. ULTEM is a thermoplastic in the polyetherimide (PEI) family that is regularly used as a high-grade material for 3D printing. This material has similar properties to polyether ether ketone (PEEK), which is another thermoplastic that has strong mechanical properties at elevated temperature conditions. While PEEK has stronger mechanical properties, ULTEM is significantly more cost efficient to acquire and process via 3D printing. Also, most 3D printers are unable to utilize PEEK because of the significantly higher temperature requirements this material imposes on a 3D printer. This work is motivated by the need to rapidly deploy robotic inspection systems within a nuclear canister environment, which exposes the material to temperatures up to 170°C (340°F), and radiation levels of 270 Gy/hr (27 krad/hr), which are significantly beyond that of conventional 3D-printed parts. The design analysis was performed via an experiment consisting of three treatment groups of dogbone ULTEM test pieces. After tensile testing all of the pieces, the material properties were compared to those of the control group. These results allow manufacturers to select a more cost-effective material to build parts to operate in such a harsh high-temperature, high-radiation environment, which could include applications in both space systems and nuclear inspection robotics. Specifically, the results were used to guide the development of a robust robotic inspection system for the Nuclear Energy University Program (NEUP) by replacing complex parts with easily-fabricated 3D-printed ULTEM pieces.

Full textAbstract:
As a result of the COVID-19 pandemic that affected most countries during the year 2020, the society had to adapt rapidly to new forms of working in which the Internet has been an essential tool. And so did the higher institutions around the world, which had to move from a face-to-face classroom environment to an online one. The change from traditional learning to online learning was so unexpected that neither the instructors nor the students may have been prepared for it and could have important consequences on students’ learning and academic achievement. The purpose of this study was to explore how university students had to struggle with online learning during the COVID-19 pandemic lockdown attending to three aspects: (a) availability and use of electronic devices, (b) personal factors, and (c) teaching factors. A non-experimental study based on a survey design was conducted, in which a convenience sample of 496 undergraduate and graduate students from two different universities located in south eastern Spain participated. The majority of the participants (66.3%) had very little or no experience in online learning and 55% considered that their academic performance was being worse than in face-to-face classes. Findings showed that most of the students had the electronic devices required for online learning (e.g. laptops, earphones, webcams, smartphones), although they mainly used laptops and earphones. They did not have other devices at home such as desktop computers, printers and scanners. The personal factors that most affected their academic performance were family problems and/or responsibilities (46.6%), psychological or emotional problems (41.6%), an inappropriate study environment (41.2%), and a bad Internet connection (31.4%). With regard to teaching factors, students complained of excessive assignments (82.6%), lack of lesson explanations (78.6%), loss of concentration during synchronous classes (64.3%), having to learn through the computer screen (58.9%), and feeling of being abandoned (57.4%), among others. In sum, university students’ struggles with online learning were more related to teaching factors than to personal and material factors. Therefore, higher education institutions and faculty should be prepared to respond to student’s needs in different teaching scenarios, and more specifically in online environments, by adapting not only their teaching styles and resources but also the way they interact with students.

Full textAbstract:
Companies can derive many benefits from educating workers on health. Yet workplaces in many lower income countries have a need for easy-to-access, on-demand health education materials. The Evidence Project/Meridian in partnership with Bayer has developed a set of health education materials for these industrial and agricultural workplaces. The materials cover important health issues facing women and men workers: - Family Planning - Engaged Fathers and Health - Healthy Timing and Spacing of Pregnancy - Menstrual Hygiene - Handwashing These materials are designed to be printed at the workplace on desktop printers, making the materials easy to access and available on demand. They are available in English, Bengali (approved by the Ministry of Health), and Arabic. The materials, in color and black and white (to save on printing costs), come in three types: - Mini-Posters (MP), to be posted in public areas - Handouts (HO), for workers to take home and containing a bit more information - Supplemental materials (QA) to reinforce learning. Each workplace can determine how best to use these materials. The Implementation Guide gives workplace health staff and managers ideas for fitting the materials into their health promotion activities. There is also a User’s Guide for Brands/Retailers, NGOs and other interested parties explaining how the materials can be used in their workplace programs in global supply chains.
