In hot-dip galvanizing process, air jet wiping control is so crucial to determine the coating thickness and uniformity of the zinc layer on the steel strip. A numerical simulation of gas-jet wiping in hot-dip galvanizing was conducted to minimize the occurrence of edge over coating (EOC). The causes of EOC were identified by contrasting and analyzing the airflow fields on the strip edge with and without a baffle. The factors influencing the airflow field on the strip edge during the change in the gap between the baffle and the strip edge were also analyzed. The effect of the distance between the air knife and the strip was evaluated. Technological parameters with on-site guidance role were obtained by combining them with the actual production to elucidate the role of the baffle in restraining the occurrence of EOC. The uniform distribution of pressure and coating thickness on the strip is achieved when the distance of the baffle from the strip edge is about 0.3 times of the jetting distance.

UNSTRUCTURED Introduction Majority of older people with hip fractures once admitted to acute hospital care are unable to return to their pre-fracture level of independence and a significant number are either newly admitted or return to residential aged care. Patient education involves family members and/or residential aged care staff as networked units, crucial for empowerment through improving health literacy. Advancement of digital technology has led to evolving solutions around optimising health care including self-management of chronic disease conditions and telerehabilitation. The aim of this study is to understand perspectives of older patients with hip fractures, their family members and residential aged carers, to inform the development of a digitally enabled model of care using a personalised digital health hub (pDHH). Methods A mixed methods study was conducted at a public tertiary care hospital in South Australia involving patients aged 50 years and above along with their family members and residential aged carers. Quantitative data, including basic demographic characteristics, access to computers and Internet were analysed using descriptive statistics. Spearman’s Rank Order Correlation was used to examine correlations between the perceived role of a pDHH in improving health and likelihood of subsequent usage. Whereas qualitative data included series of open-ended questions and findings were interpreted using constructs of capability, opportunity and motivation to help understand the factors influencing the likelihood of potential pDHH use Results Overall, 100 people were recruited in the study, representing 55 patients, 13 family members and 32 residential aged carers. The mean age of patients was 76.4 years (SD-8.4, age range 54-88) and females represented 60% of patients. Although a moderate negative correlation existed with increasing age and likelihood of pDHH usage (ρ= -0.50, p<0.001) the perceived role of the DHH in improving health had a strong positive correlation with the likelihood of pDHH usage by self (ρ=0.71, p<0.001) and by society, including friends and family members (ρ=0.75, p<0.001). Of particular note, almost all the patients (98%) believed they had a family member or friend /carer who would be able to help them to use a digital health platform. Whereas our qualitative findings suggest emphasising on complex interplay of capability, opportunity and motivation as crucial factors while designing a pDHH enabled model of care for hip fractures at a local context level. Conclusion Findings from this study contributed to understand the dynamics around capabilities, motivation and opportunities of patients, family members and formal carers as a “patient networked unit”. Future research recommendation must involve co-creation guided by iterative processes through improving understanding of factors influencing development and successful integration of complex digital healthcare interventions in real-world scenarios.

Studying the current state of cartography and ways of further developing the industry, the role of the map in the future of the society, new methods of promoting cartographic products is impossible without a deep scientific analyzing all the paths, events and factors influencing its formation and development throughout all the historic steps of cartographic production in Russia. In the article, the history of cartographic production in Russia is considered together with the development of private, state and military cartography, since, despite some differences, they have a common technical, technological and production basis. The author describes the stages of originating, formation and growth of industrial cartographic production from the beginning of the XVIII century until now. The connection between the change of political formations and technological structures with the mentioned stages of maps and atlases production is considered. Each stage is studied in detail, a step-by-step analysis was carried out, and the characteristics of each stage are described. All the events and facts are given in chronological order, highlighting especially significant moments influencing the evolution of cartographic production. The data on the volumes of printing and sales of atlases and maps by commercial and state enterprises are presented. The main trends and lines of further development of cartographic production in Russia are studied.

This new and comprehensive volume invites the reader on a tour of the exciting subfield of comparative political economy. The book provides an in-depth account of the theoretical debates surrounding different models of capitalism. Tracing the origins of the field back to Adam Smith and the French Physiocrats, the development of the study of models of political-economic governance is laid out and reviewed. Comparative Political Economy (CPE) sets itself apart from International Political Economy (IPE), focusing on domestic economic and political institutions that compose in combination diverse models of political economy. Drawing on evidence from the US, the UK, France, Germany, Sweden, and Japan, the volume affords detailed coverage of the systems of industrial relations, finance, welfare states, and the economic role of the state. There is also a chapter that charts the politics of public and private debt. Much of the focus in CPE has rested on ideas, interests, and institutions, but the subfield ought to take the role of culture more seriously. This book offers suggestions for doing so. It is intended as an introduction to the field for postgraduate students, yet it also offers new insights and fresh inspiration for established scholars. The Varieties of Capitalism approach seems to have reached an impasse, but it could be rejuvenated by exploring the composite elements of different models and what makes them hang together. Rapidly changing technological parameters, new and more recent environmental challenges, demographic change, and immigration will all affect the governance of the various political economy models throughout the OECD. The final section of the book analyses how these impending challenges will reconfigure and threaten to destabilize established national systems of capitalism.

AbstractThe aim of the study was to present a single institution’s treatment strategy for nasal dermoids and to identify factors influencing distant results. The study covered 24 surgically treated pediatric patients with nasal dermoids (NDs). The medical data concerning demographics, preoperative local inflammations and surgical procedures, form of the abnormality, imaging, surgical techniques, and a role of osteotomies and reconstructions were analyzed. The recurrence rates and distant aesthetic outcomes were assessed. The surgical approach included vertical incision in 21 patients, the external rhinoplasty approach in 2 cases, and bicoronal incision in 1 child. The intracranial extension was confirmed in 6 patients. Seven out of 8 cases with preoperative local inflammations and 3 out of 4 with secondary fistulization were < 4 years old. Nine patients required osteotomies. Three children required reconstruction of the nasal skeleton. None of the distant cosmetic results was described as hideous or unsatisfactory. The incidence of local inflammatory complications is unrelated to the age of the patients. The distant aesthetic result depends on both the initial extent of the disease and preoperative local conditions or interventions. Prompt surgical intervention is highly recommended.
