Vaccines, medicines and COVID-19 : How can WHO be given a stronger voice?
The considerable health, economic and social challenges that the world faced at the beginning of 2020 with COVID-19 continued and worsened in many parts of the world in the second-half of 2020 and into 2021. Many of these countries and nations wanted to explore COVID-19 on their own, sometimes without listening to the main international health bodies such as WHO, an agency of the United Nations system with long-standing experience and vast knowledge at the global level and of which all countries in the world are members.

Vaccine Adjuvants
The authors lay down a rational basis for vaccine adjuvant function and analyze a number of significantly distinct adjuvant-active molecules to illuminate the principles of their function and use. The focus is on specific receptor-ligand interactions, including the molecular features needed for a compound to possess adjuvant activity. The critical interface zone between the innate and adaptive immune systems is also analyzed to show how adjuvants exert their effects on T- and B-cell activation. Additional chapters address the possibility of tailoring adjuvants to yield optimally safe and effective responses.
Vacation Queueing Models : Theory and Applications
A classical queueing model consists of three parts - arrival process, service process, and queue discipline. However, a vacation queueing model has an additional part - the vacation process which is governed by a vacation policy - that can be characterized by three aspects: 1) vacation start-up rule; 2) vacation termination rule, and 3) vacation duration distribution. Hence, vacation queueing models are an extension of classical queueing theory.

Utilizing Sumac (Rhus coriaria) in pharmaceutical preparations for skin health
Aims to extract gelatin from sumac berries and incorporate it into two cosmetic products—a lip balm and a facial/hand mask—evaluating their physicochemical properties, antioxidant activity, and skinbenefiting attributes. A secondary objective is to assess the level of awareness among the Syrian population regarding sumac’s various uses beyond its culinary applications. Sumac fruits were mechanically ground and subjected to immersion, ultrasound, and microwave-assisted extraction methods, followed by filtration and evaporation to yield a viscous gelatinous extract.
Utilization of Space : Today and Tomorrow
Utilization of Space aims to serve as an authoritative overview for professionals and interested laymen by explaining scientific space utilisation, commercial and entrepreneurial issues, and technological applications.
Utilization of By-Products and Treatment of Waste in the Food Industry
The ISEKI-Food book series is a collection of books where various aspects of food safety and environmental issues are introduced and reviewed by scientists specializing in the field. In all of the books a special emphasis is placed on including case studies applicable to each specific topic. The books are intended for graduate students and senior level undergraduate students as well as professionals and researchers interested in food safety and environmental issues applicable to food safety.
Utility Maximization, Choice and Preference
The utility maximization paradigm forms the basis of many economic, psychological, cognitive and behavioral models. Since it was first devised in the eighteenth century, numerous examples have revealed the deficiencies of the concept. This book makes a contribution to overcome those deficiencies by taking into account insensitivity of measurement threshold and context of choice. It covers classic theory as a special, context-free case and gives a systematic overview of new models of utility maximization within a context-dependent threshold as well as related preference and choice models. The second edition has been updated to include the most recent developments and a new chapter on classic and new results for infinite sets.
Using the Borsuk-Ulam Theorem : Lectures on Topological Methods in Combinatorics and Geometry
Matousek's lively little textbook now shows that Lovász' insight as well as beautiful work of many others (such as Vrecica and Zivaljevic, and Sarkaria) have opened up an exciting area of mathematics that connects combinatorics, graph theory, algebraic topology and discrete geometry.
Using SPSS for Windows : Data Analysis and Graphics
The second edition of this popular guide demonstrates the process of entering and analyzing data using the latest version of SPSS (12.0), and is also appropriate for those using earlier versions of SPSS. The book is easy to follow because all procedures are outlined in a step-by-step format designed for the novice user. Students are introduced to the rationale of statistical tests and detailed explanations of results are given through clearly annotated examples of SPSS output. Topics covered range from descriptive statistics through multiple regression analysis. In addition, this guide includes topics not typically covered in other books such as probability theory, interaction effects in analysis of variance, factor analysis, and scale reliability. Chapter exercises reinforce the text examples and may be performed for further practice, for homework assignments, or in computer laboratory sessions.

Using Discrete Choice Experiments to Value Health and Health Care
Using Discrete Choice Experiments to Value Health and Health Care takes a fresh and contemporay look at the growing interest in the development and application of discrete choice experiments (DCEs) within the field of health economics. The authors have written it with the purpose of giving the reader a better understanding of issues raised in the design and application of DCEs in health economics. The use of this relatively new instrument to value health and health care has now evolved to the point where a general text is necessary. The few existing books in this area are either research monographs or focus almost entirely on more advanced topics. By contrast, this book serves as a general reference for those applying the technique to health care for the first time as well as more experienced practitioners. Thus the book is relevant to post-graduate students and applied researchers with an interest in the use of DCEs for valuing health and health care and has international appeal.
Using CAMELS as an early warning indicator to predict financial failure in Syrian banks during Covid-19 (Analytical study on a sample of Syrian banks)
Banks play an important role in financing economic development through their impact on the performance and effectiveness of deposit mobilization and other banking services. Thus, the financing of economic activity is affected, and therefore the performance of banking system is considered as one of the important requirements for the development and the growth of the national economy, Since the safety and stability of the economy of a particular country based on the stability of its banking system. Banks serve as backbone to the financial sector, which facilitate the proper utilization of financial resources of a country.
Using calcium carbonate material as a bone graft following teeth extraction
Dental bone grafting is a crucial procedure in oral and maxillofacial surgery aimed at restoring bone volume and integrity for various dental applications, particularly in preparation for dental implants. The technique involves the transplantation of bone tissue or bone substitute into areas with inadequate bone structure due to tooth loss, periodontitis, trauma or congenital defects. in this research, we will discuss the dental bone grafting, including its indications, contraindications, types of graft materials, surgical techniques, and possible complications.
Uses of technology in upper secondary mathematics education
This survey addresses the use of technology in upper secondary mathematics education from four points of view: theoretical analysis of epistemological and cognitive aspects of activity in new technology mediated learning environments, the changes brought by technology in the interactions between environment, students and teachers, the interrelations between mathematical activities and technology, skills and competencies that must be developed in teacher education. Research shows that the use of some technologies may deeply change the solving processes and contribute to impact the learning processes. The questions are which technologies to choose for which purposes, and how to integrate them, so as to maximize all students’ agency. In particular the role of the teacher in classrooms and the content of teacher education programs are critical for taking full advantage of technology in teaching practice.
