Cosmeceuticals are the latest additions to the health industry and have an ever-expanding market. They are considered to be a marriage between cosmetics and drugs and are defined as preparations applied on the body that may modify the physiological functions of the skin. However, as more cosmeceuticals are being launched in the market and more types of drugs are incorporated into the formulation, the composition of cosmeceuticals is becoming more complex. Handbook of Cosmeceutical Excipients and their Safeties summarises the current evidence relating to cosmeceuticals' side effects and highlights the important information that practitioners and consumers need to know, as well as ways to avoid the adverse effects of the excipients. Handbook of Cosmeceutical Excipients and their Safeties includes chapters covering topics such as the history of cosmeceuticals and the laws that regulate them, skin permeation, carcinogenicity as a systemic adverse effect and dermatitis as a topical adverse effect. It concludes with an appendix that gives brief information on the potency and permeability of common ingredients in cosmeceuticals. The appendix aims to highlight the maximum allowable quantity of each ingredient to ensure product safety for consumers. The appendix was prepared by compiling the ingredients of 257 products containing more than 500 compounds, collected from a hospital pharmacy in Singapore.

Sintering is the process of forming materials and components from a powder under the action of thermal energy. It is a key materials science subject: most ceramic materials and many specialist metal powder products for use in key industries such as electronics, automotive and aerospace are formed this way. Written by one of the leading experts in the field, this book offers an unrivalled introduction to sintering and sintering processes for students of materials science and engineering, and practicing engineers in industry.
The book is unique in providing a complete grounding in the principles of sintering and equal coverage of the three key sintering processes: densification, grain growth and microstructure. Students and professional engineers alike will be attracted by the emphasis on developing a detailed understanding of the theory and practical processes of sintering, the balanced coverage of ceramic and metal sintering, and the accompanying examination questions with selected solutions.
-Delivering unrivalled depth of coverage on the basis of sintering, science, including thermodynamics and polycrystalline microstructure.
-Unique in its balanced coverage of the three key sintering elements - densification, grain growth and microstructure.
-A key reference for students and engineers in materials science and engineering, accompanied by examination questions and selected solutions.

Faced with the economic pressures of globalization, many countries have sought to curb the fundamental right of workers to join trade unions and engage in collective action. In response, trade unions in developed countries have strategically used their own governments' commitments to human rights as a basis for resistance. Since the protection of human rights remains an important normative principle in global affairs, democratic countries cannot merely ignore their human rights obligations and must balance their international commitments with their desire to remain economically competitive and attractive to investors."Human Rights and Labor Solidarity" analyzes trade unions' campaigns to link local labor rights disputes to international human rights frameworks, thereby creating external scrutiny of governments. As a result of these campaigns, states engage in what political scientist Susan L. Kang terms a normative negotiation process, in which governments, trade unions, and international organizations construct and challenge a broader understanding of international labor rights norms to determine whether the conditions underlying these disputes constitute human rights violations. In three empirically rich case studies covering South Korea, the United Kingdom, and Canada, Kang demonstrates that this normative negotiation process was more successful in creating stronger protections for trade unions' rights when such changes complemented a government's other political interests. She finds that states tend not to respect stronger economically oriented human rights obligations due to the normative power of such rights alone. Instead, trade union transnational activism, coupled with sufficient political motivations, such as direct economic costs or strong rule of law obligations, contributed to changes in favor of workers' rights.
