Abstract

I enthusiastically invite you to contribute to a Special Issue of the open-access journal Polymers, focusing on “Host–Guest Polymer Complexes”, which I and two of my former PhD students, Drs. Alper Gurarslan and Ganesh Narayanan, are editing. We hope to include papers describing the syntheses, characterization, and use of host–guest polymer complexes, as well as factors that are important to their formation. Submissions that describe unusual and unique applications of host–guest polymer complexes using hosts other than traditional ones: cyclodextrins, cucurbiturils, urea, thiourea, cyclotriphosphazines, etc., are particularly encouraged.I hope that you accept our invitation to make this Special Issue one that will introduce, effectively summarize, and increase interest in this important area of polymer science.

Abstract

Social safety in social environments entails the sense of feeling safe with other people. Thus, social safety and security are very important to our life. Although research in this area has made significant progress in the past few years, there are still many social problems that require attention and further development in order to secure peace of mind. There is a very clear and accurate understanding and judgment of the overall situation of social security in the current and future period. This Special Issue focuses on a number of contemporary issues in social safety and security. The objective of this book is to rapidly disseminate the latest research and knowledge in this important area.

Abstract

Continuous casting is an industrial process whereby molten metal is solidified into a semi-finished billet, bloom, or slab for subsequent rolling in finishing mills; it is the most frequently used process to cast not only steel, but also aluminium and copper alloys. Since its widespread introduction for steel in the 1950s, it has evolved to achieve improved yield, quality, productivity and cost efficiency. It allows lower-cost production of metal sections with better quality, due to the inherently lower costs of continuous, standardized production of a product, as well as providing increased control over the process through automation. Nevertheless, challenges remain and new ones appear, as ways are sought to minimize casting defects and to cast alloys that could originally only be cast via other means. This Special Issue of the journal ""Metals"" consists of 14 research articles that cover many aspects of experimental work and theoretical modelling related to the ongoing development of continuous casting processes.

Abstract

Since 2017, the United States and Europe—among many other refugee-hosting countries—have made significant changes in their refugee policies. New visa restrictions, travel bans, and other regulations were imposed by national governments. At the local level, towns and cities responded in different ways: some resisted national policy by declaring themselves “sanctuary cities”, while others supported exclusionary policies. These different responses influenced refugees’ ability to settle and become integrated. The Refugees in Towns (RIT) project at Tufts University explores local urban integration experiences, drawing on the knowledge and perspectives of refugees and citizens in towns around the world. Since 2017, more than 30 RIT case studies have deepened our local knowledge about the factors that enable or obstruct integration, and the ways in which migrants and hosts co-exist, adapt, and struggle with integration. In this Special Issue, seven articles explore urban integration in towns in Europe (Frankfurt-Rödelheim, Germany; Newcastle, UK; Ambertois, France; Italy’s cities; and Belgrade, Serbia) and in North America: Bhutanese refugee-hosting US cities, and Antigonish, Canada. The papers explore how refugees and citizens interact; the role of officials and politicians in enabling or obstructing integration; the social, economic, and cultural impact of migration; and the ways—inclusive or exclusive—locals have responded.

Abstract

The aim of this collection of papers is to provide the reader with a cogent understanding of the role of evidence in the development of social or community-based interventions to promote inclusion oral-health and reduce oral health, health, and psychosocial inequities. In addition, this material will include various methods used for their implementation and evaluation. At the outset, the reader will be offered a working definition of inclusion oral-health, which will be modelled on the work of Luchenski et al. [1]. The interventions described are theoretically underpinned by a pluralistic definition of evidence-based practice [2] and the radical discourse of health promotion as postulated by Laverack and Labonte [3] and others [4,5]. This Special Issue will consist of eight papers, including an introduction. The first three papers will examine the various sources of evidence used to transform top-down into bottom-up community-based interventions for people experiencing homelessness; people in custody and for families residing in areas of high social deprivation. The final four papers will report on the implementation and evaluation of social or community-based interventions. This collection of research papers will highlight the importance of focusing on prevention and the adoption of a common risk factor agenda to tackle oral health, health and psychosocial inequities felt by those most excluded in our societies.

Abstract

This book is comprised of important reviews and cutting-edge original research papers concerning electrospun and electrosprayed formulations in drug delivery. Electrospinning and electrospraying have, in recent years, attracted increasing attention in the pharmaceutical sector, with research in the area advancing rapidly. It is now possible to prepare extremely complex systems using multi-fluid processes, and to increase production rates to an industrial scale. Electrospun formulations can be produced under GMP conditions and are in clinical trials. In this volume, we explore a range of topics around electrospinning and electrospraying in controlled drug delivery. Four reviews cover the exciting potential of cyclodextrin-containing fibers and the many potential biomedical applications of electrospun fibers. The use of electrospinning to prepare amorphous systems and improve the dissolution rate and solubility of poorly soluble active ingredients is addressed, and the possibilities of such materials in tissue engineering are comprehensively covered. The six original research papers cover the effect of molecular properties on API release from Eudragit-based electrospun fibers; ferulic acid solid dispersions; electrospun medicines to treat psoriasis; scale up of electrospinning and its use to produce low-dose tablets; transepithelial permeation of drugs released from electrospun fibers, and the possibilities for the synergistic chemophotothermal treatment of cancer.

Abstract

There are two constants in academic and theological discourse throughout history, they are the debate around secularization and the dialogue concerning the intersection of religion and education. Each age has had its debate about modernizing forces that drive concerns of impending secularization. In this publication this theme is approached from perspectives of teachers, of students, of policy makers and situated in a politico-historical context. Aware of the fact that in today’s plural societies one sacred canopy is non-existent anymore, cracks of the sacred canopy/canopies are described, as well as ‘the light that gets in’, the possible and challenging ways out are roughly sketched. We expect that each of the contributions of scholars of the East and the West, of the North and the South, and their presented examples and case studies, will stimulate the ongoing exploration and elaboration on the relationship between education and religion in todays’ and the coming world – work-in-progress for coming generations.

Abstract

It is well-known that colloid and interface science and petroleum production are inextricably linked. Whether in the reservoir, with its porous structure, or during recovery, crude oil is intimately associated with rock surfaces and with water, often in the form of emulsions. This situation leads to highly complex systems, comprising multiple colloids and interfaces, which require to be optimized if oil is to be recovered efficiently, both in terms of economic cost and with due concern for the environment. This book contains a compilation of contemporary research topics which illustrate various aspects of the importance of colloids and interfaces in crude oil recovery through modifying conditions between the rock, crude oil, and water in the reservoir, in order to achieve improved oil recovery. The specific topics covered relate both to conventional oils, in which waterflooding is the most common secondary and tertiary means of recovery, and to non-conventional heavy oil and natural bitumen, which require thermal recovery methods, owing to their high viscosity.

Abstract

A plethora of problems from diverse disciplines such as Mathematics, Mathematical: Biology, Chemistry, Economics, Physics, Scientific Computing and also Engineering can be formulated as an equation defined in abstract spaces using Mathematical Modelling. The solutions of these equations can be found in closed form only in special case. That is why researchers and practitioners utilize iterative procedures from which a sequence is being generated approximating the solution under some conditions on the initial data. This type of research is considered most interesting and challenging. This is our motivation for the introduction of this special issue on Iterative Procedures.
