Many researchers have attempted to use computer-aided design (C.A.D) and computer-aided manufacturing (CAM) to realize a scaffold that provides a three-dimensional (3D) environment for regeneration of tissues and organs. As a result, several 3D printing technologies, including stereolithography, deposition modeling, inkjet-based printing and selective laser sintering have been developed. Because these 3D printing technologies use computers for design and fabrication, and they can fabricate 3D scaffolds as designed; as a consequence, they can be standardized. Growth of target tissues and organs requires the presence of appropriate growth factors, so fabrication of 3Dscaffold systems that release these biomolecules has been explored. A drug delivery system (D.D.S) that administrates a pharmaceutical compound to achieve a therapeutic effect in cells, animals and humans is a key technology that delivers biomolecules without side effects caused by excessive doses. 3D printing technologies and D. D. Ss have been assembled successfully, so new possibilities for improved tissue regeneration have been suggested. If the interaction between cells and scaffold system with biomolecules can be understood and controlled, and if an optimal 3D tissue regenerating environment is realized, 3D printing technologies will become an important aspect of tissue engineering research in the near future. 3D Printing promises to produce complex biomedical devices according to computer design using patient-specific anatomical data. Since its initial use as pre-surgical visualization models and tooling molds, 3D Printing has slowly evolved to create one-of-a-kind devices, implants, scaffolds for tissue engineering, diagnostic platforms, and drug delivery systems. Fuelled by the recent explosion in public interest and access to affordable printers, there is renewed interest to combine stem cells with custom 3D scaffolds for personalized regenerative medicine. Before 3D Printing can be used routinely for the regeneration of complex tissues (e.g. bone, cartilage, muscles, vessels, nerves in the craniomaxillofacial complex), and complex organs with intricate 3D microarchitecture (e.g. liver, lymphoid organs), several technological limitations must be addressed. Until recently, tablet designs had been restricted to the relatively small number of shapes that are easily achievable using traditional manufacturing methods. As 3D printing capabilities develop further, safety and regulatory concerns are addressed and the cost of the technology falls, contract manufacturers and pharmaceutical companies that experiment with these 3D printing innovations are likely to gain a competitive edge. This review compose the basics, types & techniques used, advantages and disadvantages of 3D printing

Abstract Background The coronavirus disease 2019 (COVID-19) pandemic has severely impacted the Italian healthcare system, underscoring a dramatic shortage of specialized doctors in many disciplines. The situation affected the activity of the residents in neurology, who were also offered the possibility of being formally hired before their training completion. Aims (1) To showcase examples of clinical and research activity of residents in neurology during the COVID-19 pandemic in Italy and (2) to illustrate the point of view of Italian residents in neurology about the possibility of being hired before the completion of their residency program. Results Real-life reports from several areas in Lombardia—one of the Italian regions more affected by COVID-19—show that residents in neurology gave an outstanding demonstration of generosity, collaboration, reliability, and adaptation to the changing environment, while continuing their clinical training and research activities. A very small minority of the residents participated in the dedicated selections for being hired before completion of their training program. The large majority of them prioritized their training over the option of earlier employment. Conclusions Italian residents in neurology generously contributed to the healthcare management of the COVID-19 pandemic in many ways, while remaining determined to pursue their training. Neurology is a rapidly evolving clinical field due to continuous diagnostic and therapeutic progress. Stakeholders need to listen to the strong message conveyed by our residents in neurology and endeavor to provide them with the most adequate training, to ensure high quality of care and excellence in research in the future.

AbstractThe actual paper is related to adhesive properties of 3D objects printed on cotton textile fabrics. For practical applications of 3D prints in the textile sector, the adhesion of the printed object on the textile substrate is an important issue. In the current study, two different types of polymers are printed on cotton – polylactide acid (PLA) and polyamide 6.6 (Nylon). Altogether six cotton fabrics differing in structure, weight and thickness are evaluated. Also, the effect of washing and enzymatic desizing is investigated. For printing parameters, best results are gained for elevated process temperatures, intermediate printing speed and low Z-distance between printing head and substrate. Also, a textile treatment by washing and desizing can improve the adhesion of an afterwards applied 3D print. The presented results are quite useful for future developments of 3D printing applications on textile substrates, e.g. to implement new decorative features or protective functions.

Abstract. Part of the INGV activity is focused on the production of resources concerning Educational and Outreach projects on Geophysics and natural hazard topics. The forefront results of research activity, in fact, are periodically transferred to the public through an intense and comprehensive plan of scientific dissemination. In the past 15 years, graphic and visual communication has become an essential point of reference supporting institutional and research activities. Positive experiences are the result of a strict relationship between graphic design and scientific research, in particular the process concerning the collaborative work between designers and researchers. In projects such as the realization of museum exhibition or the production of illustrative brochures, generally designed for broad-spectrum public, the goal is to make easier the understanding and to support the scientific message, making concepts enjoyable and fruitful through the emotional involvement that visual image can arouse. The graphics and editorial products, through composition of signs and images by using different tools (colors, form, lettering) on different media (print, video, web), link to create a strong identity INGV style, in order to make them easily recognizable in Educational and Outreach projects. A project product package might include a logo or other artwork, organized text and pure design elements such as shapes and color, which unify the piece. Color is used not only to help the logo stand out from the international overview, but in our case to have a unifying outcome across all the INGV sections. A recent and stimulating experience has been the collaboration between INGV project design and its reference scientific community in order to create edu-games, products specifically designed for scientific dissemination. The edu-games have been designed to be an efficient combination of educational content and playful communicative aspects, with the aim therefore to learn while having fun.

Young Researchers

Introduction. In modern Russian science, there is a contradiction between the need for workforce rejuvenation and the orientation of the existing system on established scientists, whose interest in conducting breakthrough research has been weakened. Most promising young researchers are deprived of the freedom to independently choose the field of application of their abilities; also, scientists do not have access to resources to solve complex innovative problems and cannot directly represent the products of their work to those people, who may need them. As a rule, young scientists’ research interests are usually limited by the agenda dictated by scientific supervisors; the list of grant contests available for participation is extremely small; formalised requirements of postgraduate studies and thesis defence are conservative and full of outdated rules. In particular, all the above-mentioned problems are evident in the regions.The aim of the work is to highlight young scientists’ (e.g. employees of provincial scientific and educational organisations) motivational factors influencing the research on relevant topics and conditions for success in such research activities.Methodology and research methods. The methodological framework is based on the systemic approach, which involves a comparative analysis method and a hypothetical-deductive method. The empirical material was collected through questionnaire and expert surveys. The cluster sampling involved 148 young scientists (Doctors of Sciences under 40 years old, Candidates of Sciences under 35 years old, postgraduate students and researchers without a degree under 30 years old). In-depth interviews were conducted with the most successful respondents (N = 20) to comprehensively assess the factors of their professional activity, since it is the leaders, who primarily determine the effectiveness of functioning system.Results and scientific novelty. The motivation of a young scientist is considered as a key factor in the productivity of his or her research behaviour, which, in turn, depends on the needs of the individual and the degree of his or her satisfaction with self-realisation in the process of targeted scientific search. The authors formulated a number of hypotheses regarding the motivation of young scientists and the reasons for the decreased scientific activity in recent years based on the analysis of statistics on the state and dynamics of research activities in Russia as a whole, in regions and in individual institutions; on the comparative indicators of such activity and the benchmarking of its best practices beforehand, in the course of the pilot study (in February-March 2018). The authors developed and validated survey tools in order to test the assumptions and to check the final list of assumptions, which included a questionnaire and a list of expert assessments. The generalisation of results based on the questionnaire and the interviews of young researchers made it possible to specify their motivational features and to identify the structural core. There is a clear discrepancy between the desire of respondents to engage in research and the opportunities provided at the state and regional levels, and in the scientific and educational organisations. Traditional support mechanisms for young scientists do not allow using their research and personal potential adequately. The lack of due attention to young scientific personnel will have long-term negative consequences not only for the Russian science, but also for the entire production and economic sector of the country.Practical significance. The proposals and recommendations are made to adjust the management of research activities in the regions and to revise the research policy in order to implement the Strategy of Scientific and Technological Development of the Russian Federation.
