Environmental Regulations and Industrial Competitiveness Case Studies of Toxic Industries in Southern California - Original PDF
نویسندگان: خلاصه: 1 Chapter 1 Environmental Regulations and Industrial Competitiveness Abstract Industries in the U.S. emit billions of pounds of toxic chemicals into the environment every year, resulting in a major risk to human health. Many economists and policy makers, however, are strongly opposed to environmental regulations based on an assumption that regulations lead to a loss of jobs and a declining stan- dard of living for U.S. citizens. The empirical literature on this question has pro- duced mixed results, and this chapter critically assesses several conceptual and methodological issues that are embedded in this literature. Our thesis is that strin- gent environmental regulations have the potential to effectively and efficiently reduce toxic emissions from polluting firms and industries while having a negligible impact on the economic competitiveness of firms and industries. We investigate this thesis through three empirical case studies of polluting industries in Southern California that are highly regulated by the South Coast Air Quality Management District (AQMD): metal finishing, wood furniture, and dry cleaning. We also attempt to reveal the institutional process by which firms comply with environmen- tal regulations. Keywords Environmental regulations · Economic competitiveness · Environmental pollution · Economic externalities · Market failure · Environmental compliance · Technological uncertainty · Innovation · Adoption Introduction Over the last half century, the US federal government has played an active role in regulating the emission of toxic chemicals from polluting firms and industries (Rosenbaum, 2019; Telsey, 2016). Congress passed the Clean Air Act of 1970 “to protect and enhance the quality of the nation’s air resources so as to promote the public health and welfare and the productive capacity of the population” (US Environmental Protection Agency, 2007, p. 2). Congress also created the EPA (Environmental Protection Agency) in 1970 to implement and enforce the nation’s environmental law
Disaster Management and Information Technology Professional Response and Recovery Management in the Age of Disasters - Original PDF
نویسندگان: خلاصه: There is no one single journey when it comes to technology. For those who did not grow up as “digital natives” each has taken their own path in accepting, developing technological skills and expanding them by integrating them into their everyday work environment. Indeed, the journey continues with no hard- set destination before us. We only know that technological development and use of technology continue to expand exponentially with each passing day. What follows is therefore just one American perspective on how the profession of emergency management has adopted technologies over the decades in which the profession has existed. All the while, working daily to plan for, train, and practice for future emergency and disaster response events that are sure to come.

Blockchain Technology and Emerging Technologies - Original PDF
نویسندگان: خلاصه: ID-Based Self-encryption via Hyperledger Fabric Based Smart Contract Ilya Grishkov1, Roland Kromes1(B), Thanassis Giannetsos2, and Kaitai Liang1 1 Cyber Security Group, Delft University of Technology, Delft, The Netherlands I.Grishkov-1@student.tudelft.nl, {R.G.Kromes,Kaitai.Liang}@tudelft.nl 2 Ubitech Ltd., Digital Security and Trusted Computing Group, Athens, Greece agiannetsos@ubitech.eu Abstract. This paper offers a prototype of a Hyperledger Fabric-IPFS based network architecture including a smart contract based encryp- tion scheme that meant to improve the security of user’s data that is being uploaded to the distributed ledger. A new extension to the self- encryption scheme was deployed by integrating data owner’s identity into the encryption process. Such integration allows to permanently pre- serve ownership of the original file and link it to the person/entity who originally uploaded it. Moreover, self-encryption provides strong security guarantees that decryption of a file is computationally not feasible under the condition that the encrypted file and the key are safely stored. Keywords: Blockchain · IPFS · Self-Encryption · Security · Hyperledger Fabric 1 Introduction The modern world is increasingly adopting blockchain technology. The first major market adoption of blockchain happened in 2009 when Bitcoin was introduced [12]. Interest in blockchain solutions grew over the years and lead to the invention of Ethereum - Bitcoin peer but with support for smart contracts which are digital codes enabling the description of complete business logic [1]. The introduction of smart contracts leads to further development in the field of blockchain and cre- ated demand for more industry-friendly solutions that allow to identify users of the system (Know-Your-Customer, Anti-Money-Laundering). Hyperledger Fab- ric was then introduced as a highly modular permissioned blockchain that allows great customization to suit particular industrial needs [3]. Given its customizabil- ity and modularity, Hyperledger Fabric (HLF) is a perfect platform for extending it with various trust and privacy preservation solutions
Iron Oxides by Damien Faivre - PDF
نویسندگان: خلاصه: As the name of the book “Iron oxides: from nature to applications” suggests, iron oxides are not only widespread in the environment, but also widely used by mankind in a variety of applications (Figure 1.1). Both this ubiquitous presence in nature and the utilization as tools have been established for cen- turies and are still valid today. The first illustrative examples of iron oxides certainly are compass needle or rust (Figure 1.2). Iron oxides are present in solid, liquid, and gaseous environments, with respective examples such as rocks, as mineral inclusion in swimming bacteria or in aerosols. Depending on the type of use, several sources of iron oxides exist. Applications range from the heavy steel production to medicine and art. The different aspects of mineral formation and their use as well as modern characterization techniques are reviewed in this book
Essentials of Flow Assurance Solids in Oil and Gas Operations Understanding Fundamentals, Characterization, Prediction, Environmental Safety, and Managemen - Original PDF
نویسندگان: خلاصه: ntroduction Oil and gas were formed over millions of years from the dead bodies of plankton (tiny marine organ- isms). These prehistoric dead plankton and their naturally engineered product have dominated and shaped modern times into “the Great Oil Age,” as McKenzie-Brown, Jaremko, and Finch titled their book on the subject [1]. Petroleum shapes our modern times in two main ways: first by serving as the main source of energy, and secondly by being the raw material for thousands of products that play critical roles in modern civilization. Fossil fuels still constitute the major global source of energy, despite the recent advances in renew- able sources of energy. Fossil fuels represent 85% of global primary energy consumption [2,3], with oil remaining as the most used source in the energy mix (33%–34%), as shown in Fig. 1.1. The global consumption of and demand for hydrocarbons (oil and gas) outweigh that of other sources of energy such as coal, nuclear, and renewable energies, due to the fast-growing population and newly emerging technologies. The global energy demand is projected to more than double by 2050 due to the growth in population and economies [4]. The demand for gas is growing faster than the demand for oil, especially in developing countries [5,6]
Absorbable biodegradable polymers - Original PDF
نویسندگان: خلاصه: Egyptians sutured wounds as early as 3500 B.C. using a variety of natural polymers including treated intestines, which are the early versions of collagen-based surgical gut sutures.1 Synthetic, absorbable polyesters based on 2-hydroxyacetic acids were developed for preparing less tissue reactive alternatives to surgical gut sutures in the early 1970s. In addition to collagenbased polymers, other natural, absorbable polymers, such as albumin, chitosan, and hyaluronic acid and derivatives thereof have been used for many pharmaceutical and biomedical applications for several decades.2 Of these polymers, the application of chitosan and hyaluronic acid–based polymers has received a great deal of attention in the past 15 years for use in controlled drug delivery systems, tissue repair, tissue engineering, and controlling certain biological events.
Handbook of Biodegradable Polymers - Original PDF
نویسندگان: خلاصه: Biodegradable polymers are niche market materials finding focused applications, including agricultural applications such as mulch films, flowerpots and controlled-release fertilisers and packaging items such as carrier bags and food wrapping and containers. They have the potential to provide a solution to a range of environmental concerns: decreasing availability of landfill space, declining petrochemical sources, and also offer an alternative option to recycling. Rapra's Handbook of Biodegradable Polymers is a complete guide to the subject of biodegradable polymers and is ideal for those new to the subject or those wanting to supplement their existing knowledge. The book covers the mechanisms of degradation in various environments, by both biological and non-biological means, and the methods for measuring biodegradation. The degree and rate of biodegradation is dependent on the chemical composition of the polymer and its working environment, and so there is no single optimal method for determining biodegradation. This handbook provides discussion of international and national standards and certification procedures developed to ensure accurate communication of a material's biodegradability between producers, authorities and consumers. The book goes on to consider the characteristics, processability and application areas for biodegradable polymers, with key polymer family groups discussed.آیا کتاب مورد نظر هنوز بر روی سایت قرار نگرفته است؟ جای نگرانی نیست! کافی است بر روی گزینه سفارش کتاب کلیک کرده و درخواست خود را ثبت کنید. در کمتر از چند ساعت کتاب شما را آماده خواهیم کرد.
