Friction stir welding (FSW) of polymers is relatively a new concept among modern polymer joining techniques. This study demonstrates the applicability of FSW on 16mm thick nylon-6 plates at constant welding rate of 25mm/min and varying rotational speed between 300 to 1000RPM. A special designed tool was fabricated which has double shoulder and right-hand threaded pin profile. It has shown excellent results at relatively lower rotation speeds. Visual inspection and microstructural examination of cross sections showed that the cavities and tunnel defects appeared only at higher rotational speeds. A linear relationship was observed between temperature and rotation speed.

AbstractBackgroundClassic articles are defined as research papers with a total citation of one thousand or more. The present study is to identify and analyse the characteristics of the classic articles in apoptosis research.MethodClassic articles with total of 1,000 or more citations from Web of Science Core Collection since year of publication to the end of 2017 were basically assessed regarding their document types, languages, journals, and Web of Science categories within 1900 to 2017.ResultThe study showed 418 classic documents in apoptotic research including 260 articles published between 1972 and 2012. The most productive Web of Science category was multidisciplinary sciences. Nature published most of these classic articles followed by Cell, and Science. The most productive country and institution were United States and Harvard University respectively. The author S.J. Korsmeyer from Harvard University was the most productive in apoptosis field and published 13 classic apoptosis articles while the author J.C Reed had more potential to publish classic apoptosis articles in future. The author J.C. Reed and V.A. Fadok had equal potential to publish the same number of classic articles as first- and corresponding-author. Article of Kerr et al. in 1972 was the most popular and cited apoptosis article. The most impact article in 2017 was article entitled “Tumor-associated B7-H1 promotes T-cell apoptosis: A potential mechanism of immune evasion” by Dong et al. in 2002.ConclusionThis study seems to identify the most industrious authors, institutions, and countries in the field of apoptosis research. It also tends to reveal the historical and discoveries related to the pathophysiology of apoptosis as well as the most impact publications on apoptosis studies.

The late 20th and early 21st centuries were marked by sudden and rapid changes, including the free flow and interconnectedness of people, information, and trade, but the most prominent changes pertain to scientific and technological advancements. New connections were also found between different scientific disciplines, which had previously been considered unrelated, thus causing the breakthrough of multidisciplinary sciences. Unfortunately, the 21st century has so far been ridden with natural disasters worldwide. According to EM-DAT (Emergency Event Database 2015), the consequences and losses caused by natural disasters have been increasing. Thus, risk assessment became a priority for reducing the risk from natural disasters. Risk assessment is the essence of risk management. Just as there are connections between various scientific disciplines, so are there connections between various disastrous events, which resulted in the increased importance of the concept of multi-risk. Multi-hazard risk assessment is a key step in integrated risk management. Over the last decade, the interest in multi-risk assessment has grown in Europe but also globally.

Abstract Considerable progress has been made in improving child health and well-being in Europe over the past 40 years, with great reductions in neonatal, and child deaths, and in deaths from causes such as vaccine-preventable diseases. Paediatric primary care (PPC) has significantly contributed to these advances. However, there are still differences between and within countries regarding the content and organizations of primary care for children that might have an impact on important aspects such as access and availability of primary care. These cross-country and within-country differences together with current and future challenges in child health care, such as increasing prevalence of chronic and long-term conditions, fragmentation of care and shortage of health personnel, pose a complex challenge for European countries. Working towards an approach to tackle these challenges requires the vision, input and collaboration of multidisciplinary sciences. In this workshop four perspectives are brought together with the goal to learn from each other’s experiences and to establish a common knowledge base on how to collaborate between different disciplines and sciences to bring PPC to a next level. The first presentation will be from a public health perspective and is about the comparison of actual and desired organization and content of adolescent health services. The second presentation will be a paediatrician’s perspective and stresses the importance of an adequately trained paediatric workforce. The third presentation will be from a sociological perspective and focuses on the societal scale drivers framing health among children and their families. In the final presentation a philosophical perspective will be given on adherence to therapy, resilience and resonance in the treatment triangle of ‘patient-family-therapist’. The presentations will be followed by a round table discussion in which the audience will be involved: the presenters will answer questions and discuss with the audience how we should create better and sustainable PCP by making use of multiple disciplines and sciences. Key messages Differences between and within countries regarding the content and organizations of primary care for children might have an impact on important aspects such as access and availability of primary care. Working towards an approach to tackle challenges in paediatric primary care requires the vision, input and collaboration of multidisciplinary sciences.

AbstractWe consider a model for prion proliferation that includes prion polymerization, polymer splitting, and polymer joining. The model consists of an ordinary differential equation for the prion monomers and a hyperbolic nonlinear differential equation with integral terms for the prion polymers and was shown to possess global weak solutions for unbounded reaction rates [
