Ozone Journal by Peter Balakian Pdf

"A sequel of sorts to "Ziggurat," published in the Phoenix Poets series in 2010, the title poem from "Ozone Journal" recounts the memory of the speaker's excavating the bones of Armenian genocide victims in the Syrian desert with a TV journalist crew in 2009. The speaker "dreams back," as it were, to the 1980s, when, as a young man in his thirties and caring for a young daughter after a recent divorce, he is having to juggle both personal and cultural/historical complexities living as a single parent in Manhattan. The poems create a montage that has the feel of history as lived experience, with the speaker struggling with the nature of memory as the poems move constantly back and forth to the Syrian desert, the dissolution of his marriage, visits and conversations with a cousin dying of AIDS, and encounters with famous jazz producers at Columbia Records to discuss music. In this book, Peter Balakian aims at the bigger picture of humanity's history of atrocity and trauma, but through short vignettes grounded in everyday situations, and in particular times and places"--Publisher's info.

Remote Sensing and Atmospheric Ozone by Arthur Philip Cracknell,Costas Varotsos Pdf

The destruction of the ozone layer, together with global warming, is one of the hot environmental topics of today. This book examines the effect of human activities on atmospheric ozone, namely the increase of tropospheric ozone and the general diminution of stratospheric ozone and the production of the Antarctic ozone hole. Also discussed is the role of remote sensing techniques in the understanding of the effects of human activities on atmospheric ozone as well as in the development of social and political awareness of the damage to the ozone layer by man-made chemicals, principally CFCs. This led to the formulation and ratification in 1989 of the Montreal Protocol on controlling/banning the manufacture and use of chemicals that damage the ozone layer. Since then, remote sensing has played a key role in monitoring atmospheric ozone concentration and determining the success of the Montreal Protocol in protecting the ozone layer from further damage. In this book, the renowned authors discuss the sophisticated instruments that have been launched into space to study not only ozone but also other trace gases in the atmosphere, some of which play a key role in the generation and destruction of ozone in the atmosphere. Professors Cracknell and Varotsos also examine the satellite-flown instruments which are involved in monitoring the absorption of solar ultraviolet light in the atmosphere in relation both to the generation and destruction of ozone and consequently to human health. This scholarly book, written by the foremost experts in the field, looks at remote sensing and its employment in the various aspects of ozone science. It is widely acknowledged that global warming, due to anthropogenic greenhouse gases emissions, represents a threat to the sustainability of human life on Earth. However, many other threats are potentially just as serious, including atmospheric pollution, ozone depletion, water pollution, the degradation of agricultural land, deforestation, the depletion of the world's mineral resources and population growth.

Twenty Years of Ozone Decline by Christos Zerefos,G. Contopoulos,Gregory Skalkeas Pdf

Homer speaks of lightning bolts after which ‘a grim reek of sulphur bursts forth’ and the air was ‘?lled with reeking brimstone’. (Homer 3000 BC). The odour was not actually the smell of sulphur dioxide associated with burning sulphur, but rather was the ?rst recorded detection of the presence of another strong odour, that of ozone (O ) in Earth’s atmosphere. These molecules were formed by the passage of 3 lightning through the air, created by splitting the abundant molecular oxygen (O ) 2 molecules into two, followed by the addition of each of the free O atoms to another O to form the triatomic product. In fact, most of the ozone molecules present 2 in the atmosphere at any time have been made by this same two-step splitti- plus-combination process, although the initiating cause usually begins with very energetic solar ultraviolet (UV) radiation rather than lightning. Many thousands of years later, the modern history of ozone began with its synthesis in the laboratory of H. F. Schonbein in 1840 (Nolte 1999), although the positive con?rmation of its three-oxygen atom chemical formula came along sometime later. Scienti?c interest in high-altitude stratospheric ozone dates back to 1881 when Hartley measured the spectrum of ozone in the laboratory and found that its ability to absorb UV light extended only to 293nm at the long wavelength end (Hartley 1881a).

Chemistry of Ozone in Water and Wastewater Treatment by Clemens von Sonntag,Urs von Gunten Pdf

Even though ozone has been applied for a long time for disinfection and oxidation in water treatment, there is lack of critical information related to transformation of organic compounds. This has become more important in recent years, because there is considerable concern about the formation of potentially harmful degradation products as well as oxidation products from the reaction with the matrix components. In recent years, a wealth of information on the products that are formed has accumulated, and substantial progress in understanding mechanistic details of ozone reactions in aqueous solution has been made. Based on the latter, this may allow us to predict the products of as yet not studied systems and assist in evaluating toxic potentials in case certain classes are known to show such effects. Keeping this in mind, Chemistry of Ozone in Water and Wastewater Treatment: From Basic Principles to Applications discusses mechanistic details of ozone reactions as much as they are known to date and applies them to the large body of studies on micropollutant degradation (such as pharmaceuticals and endocrine disruptors) that is already available. Extensively quoting the literature and updating the available compilation of ozone rate constants gives the reader a text at hand on which his research can be based. Moreover, those that are responsible for planning or operation of ozonation steps in drinking water and wastewater treatment plants will find salient information in a compact form that otherwise is quite disperse. A critical compilation of rate constants for the various classes of compounds is given in each chapter, including all the recent publications. This is a very useful source of information for researchers and practitioners who need kinetic information on emerging contaminants. Furthermore, each chapter contains a large selection of examples of reaction mechanisms for the transformation of micropollutants such as pharmaceuticals, pesticides, fuel additives, solvents, taste and odor compounds, cyanotoxins.

Ozone Pollution and Plant Health: Understanding the Impacts and Solutions for Sustainable Agriculture by Anonim Pdf

Advances in Botanical Research Volume 108: Ozone Pollution and Plant Health: Understanding the Impacts and Solutions for Sustainable Agriculture provides a comprehensive overview of the harmful effects of tropospheric ozone (O3) pollution on crop productivity, with a focus on how it is measured and modeled under climate change scenarios. The book discusses the sources of O3 pollution, including anthropogenic precursor gases, and how O3 exposure can impair photosynthesis, reduce gas exchange, induce early leaf senescence, and hamper growth in natural vegetation and crops. The book highlights how O3 interacts with plant physiology and metabolism, including through the activation of signal transduction pathways, changes in phytohormone signaling, and modulation of reactive oxygen species (ROS) generation and signaling. The book also explores the experimental and modeling methods used to assess the effects of O3 on crops, with a focus on studies conducted in Asia. The book emphasizes the importance of understanding the implications of ozone pollution for ensuring food security and protecting human and environmental health and suggests strategies such as using ozone-resistant cultivars of plants and crops. Additionally, the book discusses the broader context of air pollution and its impact on crop productivity, including the effects of other air pollutants on plants and crops and the need for mitigation strategies and policies to address agricultural losses. This book is essential reading for early-career researchers, sustainable agriculture practitioners, and policymakers interested in understanding the complex interactions between ozone pollution and plant productivity and finding solutions to mitigate the detrimental effects of ozone pollution on crops in a changing climate. Discusses the impact of O3 pollution on plant productivity and the methods for measuring and modeling this under climate change scenarios Reviews recent findings about the target sites for O3 in plants, O3-induced stomatal regulation by phytohormone signaling, and plants' responses related to phytohormone biosynthesis, ROS generation, and signaling in exposure to O3 Provides an overview of ozone air quality, ozone effects on plant and crop, and experimental and modeling methods used to assess the effects. It focuses on the results of the experimental and modeling studies of the ozone effects on agricultural crops in Asia Covers the effects of common air pollutants on crops and their pathways of exposure to plants. It also discusses the disturbance in the biochemistry of plants and their metabolisms due to air pollution, and some laws implemented for air pollution control in Pakistan

Ozone in Nature and Practice by Jan Derco,Marian Koman Pdf

Ozone has an important and irreplaceable function in nature and human society. It preserves life on the Earth by stratospheric ozone layer. On the other hand, the formation of ground-level ozone by reactions of hydrocarbons with nitrogen dioxide in the presence of sunlight has adverse effects on humans and animals as well as on various materials. This book concentrates on the protection of stratospheric ozone and prevention of ground-level ozone formation; applications of its strong oxidizing properties in the treatment of water, wastewater and sludge; odor and color removal; uses in medicine as a disinfectant; and various other ozone therapies. It also deals with catalytic ozonation in water treatment, control methods for ozone applications on biological systems, various areas of ozone use in dental care, follow-up therapy and prevention.

OZONE by Velio Bocci Pdf

Oxygen-Ozone therapy is a complementary approach less known than homeopathy and acupuncture because it has come of age only three decades ago. This book clarifies that, in the often nebulous field of natural medicine, the biological bases of ozone therapy are totally in line with classical biochemistry, physiological and pharmacological knowledge. Ozone is an oxidizing molecule, a sort of super active oxygen, which, by reacting with blood components generates a number of chemical messengers responsible for activating crucial biological functions such as oxygen delivery, immune activation, release of hormones and induction of antioxidant enzymes, which is an exceptional property for correcting the chronic oxidative stress present in atherosclerosis, diabetes and cancer. Moreover, by inducing nitric oxide synthase, ozone therapy may mobilize endogenous stem cells, which will promote regeneration of ischemic tissues. The description of these phenomena offers the first comprehensive picture for understanding how ozone works and why. When properly used as a real drug within therapeutic range, ozone therapy does not only does not procure adverse effects but yields a feeling of wellness. Half the book describes the value of ozone treatment in several diseases, particularly cutanious infection and vascular diseases where ozone really behaves as a “wonder drug”. The book has been written for clinical researchers, physicians and ozone therapists, but also for the layman or the patient interested in this therapy.

Decontamination of Fresh and Minimally Processed Produce by Vicente M. Gómez-López Pdf

Attempts to provide safer and higher quality fresh and minimally processed produce have given rise to a wide variety of decontamination methods, each of which have been extensively researched in recent years. Decontamination of Fresh and Minimally Processed Produce is the first book to provide a systematic view of the different types of decontaminants for fresh and minimally processed produce. By describing the different effects – microbiological, sensory, nutritional and toxicological – of decontamination treatments, a team of internationally respected authors reveals not only the impact of decontaminants on food safety, but also on microbial spoilage, vegetable physiology, sensory quality, nutritional and phytochemical content and shelf-life. Regulatory and toxicological issues are also addressed. The book first examines how produce becomes contaminated, the surface characteristics of produce related to bacterial attachment, biofilm formation and resistance, and sublethal damage and its implications for decontamination. After reviewing how produce is washed and minimally processed, the various decontamination methods are then explored in depth, in terms of definition, generation devices, microbial inactivation mechanisms, and effects on food safety. Decontaminants covered include: chlorine, electrolyzed oxidizing water, chlorine dioxide, ozone, hydrogen peroxide, peroxyacetic acid, essential oils and edible films and coatings. Other decontamination methods addressed are biological strategies (bacteriophages, protective cultures, bacteriocins and quorum sensing) and physical methods (mild heat, continuous UV light, ionizing radiation) and various combinations of these methods through hurdle technology. The book concludes with descriptions of post-decontamination methods related to storage, such as modified atmosphere packaging, the cold chain, and modeling tools for predicting microbial growth and inactivation. The many methods and effects of decontamination are detailed, enabling industry professionals to understand the available state-of-the-art methods and select the most suitable approach for their purposes. The book serves as a compendium of information for food researchers and students of pre- and postharvest technology, food microbiology and food technology in general. The structure of the book allows easy comparisons among methods, and searching information by microorganism, produce, and quality traits.

Oxygen-Ozone Therapy by V. Bocci Pdf

When I was about fifteen, my Biological Seiences teacher, Prof. N. Benacchio, lent me a book by Paul de Kruif "The Microbe Hunters" and I remained fascinated by infectious diseases. I was intrigued by the potency of virulent bacteria which are constantly trying to invade our bodies and often overcome what today we call innate and adoptive immunity. Indeed, shortly after that, I was struck by his tragic death due to peritonitis. Later, while studying medicine (although medical knowledge in the 1950s was almost primordial compared with today), I soon realised how the various biological systems were wonderfully organised but at the same time frail and how our life could end in a few minutes. Slowly it became obvious that our "wellness" was the result of a dynamic and very unstable equilibrium between health and disease. This unstable equilibrium could be broken forever if the body's response could not reverse the pathological state. I stuck a sort ofposter on the wall ofmy room with these three words and connecting arrows: HEALTH~-? DISEASE -? DEATH As I don't believe in another world after death, it became obvious to me that we should make every possible effort not only to delay death, but to try always to shift the equilibrium to the left. In this book, I will try to show that this can be achieved, as a last resort, even with ozonetherapy.
