    Description: The 60–80s of the last century were the period of the most rapid development of commercial oceanology in the Azov and Black Sea Scientific Research Institute of Marine Fisheries and Oceanography (AzCherNIRO, further renamed YugNIRO). In addition to the monitoring of oceanographic processes, it was involved in the areas of general marine ecology, monitoring of marine pollution, and space oceanology. Oceanographic information is used in forecasting the state of aquatic ecosystems at various timescales and is crucial for fishing forecasts. In 1981, a satellite data reception center was established in AzCherNIRO. In the 80–90s, in YugNIRO, an optimal procedure was created for multidimensional predictive monitoring of the state of the Black Sea ecosystem. In September 1986, within the Laboratory of Commercial Oceanology of the Black Sea, a group for the conservation of marine ecosystems was created, which turned into a sector in January 1989, and into a separate laboratory in December 1996. Its reasearchers carried out multidisciplinary environmental studies, investigating the ecological status of the aquatic areas affected by the facilities of the marine industry during their operation, monitoring the level of soil contamination, and excercising the toxicological control of fish and fish products. YugNIRO oceanological studies conducted in the World Ocean from the early 1970s to the early 1990s made it possible to link the productivity and catches of exploitable species to the atmospheric circulation, changes in the climatic fields of currents, as well as to the geo- and heliophysical factors, which enabled the fishing predictions with a one-year lead time or more for the fishing areas of the Central, Southeastern and Southwestern Indian Ocean, the Patagonian Shelf, and the Indian Ocean sector of Antarctica. In the 70–90s and early 2000s, YugNIRO conducted marine geological studies facilitating fishing operations and environmental protection in the Gulf of Aden, on the bottom elevations of the tropical and subtropical parts of the Indian Ocean, in the Antarctic Shelf area, and in the Black and Azov Seas. This article lays down the current major goals and prospects of commercial oceanology.
    Description: 60–80-е годы прошедшего столетия были в АзЧерНИРО (ЮгНИРО) периодом наиболее активного развития промысловой океанологии. Кроме мониторинга океанографических процессов она начала внедряться в сферы общей экологии моря, мониторинга загрязнения моря, космической океанологии. Океанографическая информация используется при разработке прогнозов состояния водных экосистем различной заблаговременности и является неотъемлемой составляющей рыбопромысловых прогнозов. В 1981 г. в АзЧерНИРО был создан центр приема спутниковой информации. В 1980–1990-х гг. в ЮгНИРО была создана оптимальная для Черного моря схема комплексного прогностического мониторинга состояния его экосистемы. В сентябре 1986 г. в составе лаборатории промысловой океанологии Черного моря была создана группа, в январе 1989 г. — сектор, в декабре 1996 г. — лаборатория охраны морских экосистем. Сотрудниками лаборатории проводились комплексные экологические исследования состояния акваторий предприятий морехозяйственого комплекса в условиях их производственной деятельности, контроль уровня загрязненности почв, токсикологический контроль рыбы и рыбопродукции. Океанологические исследования ЮгНИРО, проводимые в Мировом океане с начала 1970-х до начала 1990-х гг., позволили получить систему связей урожайности и вылова промысловых объектов с особенностями атмосферной циркуляции, изменениями макромасштабных полей течений, гео- и гелиофизическими факторам для прогноза промысловых характеристик с заблаговременностью год и более в промысловых районах центральной, юго-восточной и юго-западной частей Индийского океана, в районе Патагонского шельфа, в индоокеанском секторе Антарктики. Выполнение морских геологических работ в рыбопромысловых и природоохранных целях проводилось ЮгНИРО в 1970–1990-х и в начале 2000-х гг. в Аденском заливе, на поднятиях тропической и субтропической частей Индийского океана, на шельфе Антарктиды, в Черном и Азовском морях. В статье формулируются основные современные цели и пути развития промысловой океанологии.

    Description: La producción de ostión en Cuba aumenta hacia el este, y los máximos de abundancia y captura se presentan en la zona costera cercana a la cuenca del río Cauto, en la región correspondiente al municipio Manzanillo, provincia de Granma. En esta región habitan el ostión de mangle antillano (Crassostrea rhizophorae Guilding, 1828), y el ostión americano (Crassostrea virginica Gmelin, 1791). Aunque la tendencia histórica ha sido al incremento, posterior a 2013 (853 t) la producción promedio anual disminuye a 307 t. El objetivo de esta investigación fue evaluar el estado actual del recurso ostión y su aprovechamiento industrial en la región del golfo de Guacanayabo, en relación a la situación ambiental de sus hábitats. Se realizó un diagnóstico de la pesquería de ostión y de la gestión ambiental de la pesca extractiva para determinar impactos ecosistémicos. Se identificaron como principales factores de impacto negativo, que inciden sobre las poblaciones de ostión y sus hábitats, el incumplimiento del periodo de veda, el manejo inadecuado de la pesca extractiva, y eventos de contaminación, que afectan los bienes y servicios ecosistémicos del manglar y reducen las poblaciones de ostión. Se propone la ostricultura artesanal como alternativa pesquera sostenible y se proyectó un plan de producción de ostión para 2023-2030. Se estimó que a calidad ambiental de la región donde se desarrollan las especies de interés es adecuada para su desarrollo.
    Description: Oyster production in Cuba increases to the east, and the maximum abundance and catch occur in the coastal zone near the Cauto river basin, in the region corresponding to the Manzanillo municipality, Granma province. The West Indian mangrove oyster (Crassostrea rhizophorae Guilding, 1828), and the American oyster (Crassostrea virginica Gmelin, 1791) inhabit this region. Although the historical trend has been to increase, after 2013 (853 t) the average annual production decreases to 307 t. The objective of this research was to evaluate the current state of the oyster resource and its industrial use in the region of the Guacanayabo Gulf, in relation to the environmental situation of its habitats. A diagnosis of the oyster fishery and the environmental management of extractive fishing was carried out to determine ecosystem impacts. The main factors of negative impact, which affect oyster populations and their habitats, were identified as non-compliance with the closed season, inadequate management of extractive fishing, and pollution events, which affect the goods and ecosystem services of the mangrove and reduce oyster populations. Artisanal oyster farming is proposed as a sustainable fishing alternative and an oyster production plan was projected for 2023-2030. It is estimated that the environmental quality of the region where the species of interest develop is adequate for their development.

    Description: Redox reactions are involved in biochemistry, energy, corrosion, and much more. In both biology and electrochemistry, the redox reaction is complex and varied. For example, redox shuttles in supercapacitors show aspects of molecular electrochemistry applied to electrode porosity. In pseudocapacitors, the formalism associated with their electrochemical response requires investigation and formalism. Similarly, the simple definition of redox potential opens fundamental questions about its measurement in solutions without supporting salts. This book illustrates the variety of redox reactions in its examination of the importance of redox molecules in the development of new electrical energy storage devices.

    Description: We are living in a critical time, both for humanity and the planet, which has led us to look for more sustainable formulas to interact with the environment. One of the important changes in the design and operation of chemical processes is the search for environmentally friendly technologies. Supercritical carbon dioxide has been revealed as a promising environmentally friendly solvent that is energy efficient, selective and capable of reducing waste, making it a promising alternative to conventional organic solvents. However, reliable and versatile mathematical models of phase equilibrium thermodynamics are needed for the use of supercritical carbon dioxide in process design and viability studies. This book reviews experimental procedures for obtaining high-pressure phase equilibria data and describes the phase diagrams of binary mixtures and some thermodynamic models capable of determining the conditions of phase equilibria at high pressures. These concepts are applied to the components of the transesterification reaction of rac-2-pentanol with a vinyl ester, which is important in the pharmaceutical industry because (S)-2-pentanol can be obtained as a reaction product. This product is a key intermediate in the synthesis of drugs against Alzheimer’s disease.

    Description: In recent decades, artificial porous structures have attracted increasing enthusiasm from researchers inspired by the fascinating molecular pores in nature and their unique biological functions. Although substantial achievements in porous materials have been realized, the construction of topologically designed pores is still challenging. Recently, the emergence of covalent organic frameworks (COFs), which are constructed based on organic and polymer chemistry, has made it possible to design artificial pores with controlled pore size, topology and interface properties. COFs are crystalline porous materials constructed by the precise reticulation of organic building blocks via dynamic covalent bonds. Distinct from non-covalent interactions which tend to produce isostructures, covalent bonds enable accurate pore design owing to their predetermined reaction pathways. In addition, the appropriate polycondensation of organic building units enables the formation of extended two-dimensional (2D) and three-dimensional (3D) polymer architectures with periodically ordered skeletons and well-defined pores. With their large surface area, tailorable structures, and tunable chemistry, COFs are regarded as potentially superior candidates for various applications including catalysis, energy storage and conversion, mass transport and biotechnology. This book examines the historic achievement of COFs, providing clear and comprehensive guidance for researchers on their structural design, synthetic protocols and functional exploration.

    Description: Fluoride covers a continuum of topics that are frequently studied in the broad area of fluoride (F) research. It provides an overview of the primary sources of environmental fluoride in typical high-fluoride environments and demonstrates the transitions and transformations that emerge and culminate in hydro-geochemical interactions that result in fluoride-fouling of large portions of the world’s water and agricultural resources. This way, the book pinpoints the connection between F enrichment of water sources and the prevalence of endemic fluorosis in certain areas of the world. In order to contribute to a better understanding of the global fluoride problem, new fluoride detection and quantification technologies are proposed with an in-depth analysis of emerging trends in the use of portable user-friendly devices in point-of-use measurements of water fluoride. This has been presented against the backdrop of a robust overview of traditional fluoride quantification methodologies that are still in wide application among the scientific communities. In addressing fluoride toxicities, which are not limited to dental and skeletal dilapidations, the authors have explored the role of natural antioxidants in ameliorating physiological fluoride-induced noxious effects in mammalian systems. Nonetheless, since community dependence on high-fluoride water due to a lack of alternative clean water sources remains to be the principal pathway of human fluoride over-exposure, a review chapter on F mitigation techniques applied all over the world is incorporated aiming at providing a succinct overview of water defluoridation techniques and strategies being used to combat the impacts of human F overexposure around the globe. Since every cloud has a silvery lining, the possibility of using ammonium fluorides as a novel reagent in mineral processing has been considered convenient industrial fluorinating agents, which present the possibility of complete regeneration that is not afforded by the reagents presently used in decomposing silicon component of the ores.

    Description: The book comprises 14 chapters covering all the issues related to water desalination. These chapters emphasize the relationship between problems encountered with the use of feed water, the processes developed to address them, the operation of the required plants and solutions actually implemented. This compendium will assist designers, engineers and investigators to select the process and plant configuration that are most appropriate for the particular feed water to be used, for the geographic region considered, as well as for the characteristics required of the treated water produced. This survey offers a comprehensive, hierarchical and logical assessment of the entire desalination industry. It starts with the worldwide scarcity of water and energy, continues with the thermal - and membrane-based processes and, finally, presents the design and operation of large and small desalination plants. As such, it covers all the scientific, technological and economical aspects of this critical industry, not disregarding its environmental and social points of view. One of InTech's books has received widespread praise across a number of key publications. Desalination, Trends and Technologies (Ed. Schorr, M. 2011) has been reviewed in Corrosion Engineering, Science & Technology – the official magazine for the Institute of Materials, Minerals & Mining, and Taylor & Francis's Desalination Publications. Praised for its “multi-faceted content [which] contributes to enrich it,” and described as “an essential companion...[that] enables the reader to gain a deeper understanding of the desalination industry,” this book is testament to the quality improvements we have been striving towards over the last twelve months.

    Description: Surfactants are ubiquitous and have applications in diverse areas, including food, cosmetics, detergents, lubricants, enhanced oil recovery (EOR), and targeted drug delivery systems. Their wide diversity of applications owes to their unique structure, namely, a hydrophilic and a hydrophobic group present in the same molecule. Although most surfactants used industrially are synthetic, there is a growing need for natural surfactants, as the latter is obtainable from renewable sources and are less toxic and highly biodegradable in contrast to their synthetic counterparts. This book is a compilation of interesting articles by various experts that cover various applications of both synthetic and natural surfactants.

    Description: Food waste is an abundant and inexpensive resource for the production of renewable fuels. Biocrude yields obtained from hydrothermal liquefaction (HTL) of food waste can be boosted using hydroxyapatite (HAP) as an inexpensive and abundant catalyst. Combining HAP with an inexpensive homogeneous base increased biocrude yield from 14 ± 1 to 37 ± 3%, resulting in the recovery of 49 ± 2% of the energy contained in the food waste feed. Detailed product analysis revealed the importance of fatty-acid oligomerization during biocrude formation, highlighting the role of acid-base catalysts in promoting condensation reactions. Economic and environmental analysis found that the new technology has the potential to reduce US greenhouse gas emissions by 2.6% while producing renewable diesel with a minimum fuel selling price of $1.06/GGE. HAP can play a role in transforming food waste from a liability to a renewable fuel.

    Description: Chemiebezogene Kompetenzen werden bereits im Sachunterricht der Grundschule entwickelt und sollen im Chemieunterricht der Sekundarstufe I aufgegriffen und weiterentwickelt werden. Ziel dieser Studie war es, die chemiebezogenen Kompetenzen der Schülerinnen und Schüler in der Übergangsphase zwischen Sachunterricht und Chemieunterricht zu analysieren. In einer Ergänzungsstudie wurden zusätzlich sowohl die Auswirkungen der Schulschließungen aufgrund der SARS-CoV-II Pandemie auf die Kompetenzen der Schülerinnen und Schüler als auch der Einfluss einer veränderten Testadministration untersucht. Insgesamt wurden die Kompetenzen von 2262 Lernenden der Jahrgangsstufen 5 bis 9 zu drei Messzeitpunkten analysiert. Die Ergebnisse zeigen, dass die chemiebezogenen Kompetenzen sowohl zum Ende der Grundschulzeit als auch zu Beginn des Chemieunterrichts über alle Kompetenzbereiche hinweg sehr heterogen ausfallen. Dennoch sind sie zu Beginn des Chemieunterrichts in einigen Kompetenzbereichen höher ausgeprägt als zum Ende der Grundschulzeit. Nach den pandemiebedingten Schulschließungen waren die Kompetenzen ähnlich ausgeprägt wie in den gleichen Jahrgangsstufen vor den Schulschließungen. Eine während der Schulschließungen notwendige Bearbeitung der Testhefte von zu Hause aus führte vor allem bei den jüngeren Schülerinnen und Schülern zu besseren Testergebnissen als die Bearbeitung in der Schule. Um die Entwicklung chemiebezogener Kompetenzen in der Übergangsphase zu optimieren, sollte der Erwerb dieser Kompetenzen bereits im Sachunterricht einheitlicher gestaltet werden.

    Description: In 2005, the hybrid model was published by Prof. H.-D. Alber and Prof. P. Zhu as an alternative to the Allen-Cahn model for the description of phase field transformations. With low interfacial energy, it is more efficient, since the resolution of the diffuse interface is numerically broader for the same solution accuracy and allows coarser meshing. The solutions of both models are associated with energy minimisation and in this work the error terms introduced in the earlier publications are discussed and documented using one and two dimensional numerical simulations. In the last part of this book, phase field problems, initially not coupled with material equations, are combined with linear elasticity and, after simple introductory examples, a growing martensitic inclusion is simulated and compared with literature data. In addition to the confirmed numerical advantage, another phenomenon not previously described in the literature is found: with the hybrid model, in contrast to the examples calculated with the Allen-Cahn model, an inclusion driven mainly by curvature energy does not disappear completely. The opposite problem prevents inclusions from growing from very small initial configurations, but this fact can be remedied by a very finely chosen diffuse interface width and by analysing and adjusting the terms that generate the modelling errors. The last example shows that the hybrid model can be used with numerical advantages despite the above mentioned peculiarities.

    Description: Das selbstgesteuerte Experimentieren ist laut den nationalen Bildungsstandards sowie den Lehrplänen im Fach Chemie ein wichtiger Bestandteil der naturwissenschaftlichen Schulbildung. Offene Experimentierformen sind jedoch wenig etabliert. Um das selbstgesteuerte Experimentieren in die Unterrichtspraxis zu implementieren, wurde im Rahmen dieses Forschungsprojekts eine eintägige Lehrkräftefortbildung zur Konzeption von selbstgesteuerten Experimenten im Chemieunterricht durchgeführt. Dazu wurde ein literaturbasiertes Strukturierungskonzept entwickelt, mit dem die Lehrkräfte kochbuchartige Schulversuche zu selbstgesteuerten und kompetenzorientierten Experimenten mit beliebigen Öffnungsgraden modifizieren können. Begleitend zur Fortbildung wurde im Prä-Post-Follow-Up-Design das fachdidaktische Wissen der Teilnehmenden hinsichtlich der Planung von selbstgesteuerten Experimenten empirisch überprüft. Zur Erfassung dieses Konstrukts wurde ein neues Messinstrument literaturbasiert entwickelt und die Güte des Messinstruments evaluiert. Die Auswertungen zeigen, dass die Fortbildung hinsichtlich des fachdidaktischen Wissens der Lehrkräfte kurz- sowie langfristig lernförderlich ist und die Fortbildung von den Teilnehmenden positiv bewertet wird. Die Reliabilitätsanalyse sowie die Validierungsstudie zeigen, dass der Test sowohl reliabel als auch valide ist. In Folgestudien könnte die langfristige Verhaltensänderung der Lehrkräfte bezüglich der Implementierung des selbstgesteuerten Experimentierens in den Unterricht untersucht werden.

    Description: Konsumgüter werden beispielsweise mit Slogans wie "Gut in Bio. Schlecht in Chemie." beworben. Dabei wird intendiert, sich gezielt von "Chemie" abzugrenzen und sich das positive Bild von "Natur" zu Nutze zu machen. Dies prägt die öffentliche Meinung und trägt zu einer antagonistisch-wertenden Sicht von "Chemie" und "Natur" bei. Dass Chemie als Naturwissenschaft der Beschreibung der Natur dient, um deren Stoffe und Stoffumwandlungen zu erklären, ist dem Laien selten bewusst. Chemie findet überall statt, insbesondere in der Natur! Genau an diesem Punkt setzt das Unterrichtskonzept "Chemie Pur - Unterrichten in der Naturglqq an. Ziel ist es, im Freiland, mit direkt vor Ort gewonnenen Naturstoffen, Umweltprozesse experimentell zu erarbeiten. Die projektbegleitende Evaluationsstudie stellte sich der Forschungsfrage, wie sich das Unterrichtskonzept auf das Fach- und Sachinteresse, auf die Naturverbundenheit sowie auf die Einstellung zu Chemie und Natur von Schülerinnen und Schülern der Sekundarstufe II auswirkt. Die Auswertung der Fragebogenergebnisse mit latenten Veränderungsmodellen haben gezeigt, dass die Intervention im Freiland das inhaltsbezogene Sachinteresse steigert und die Einstellung zu Chemie und Natur positiv beeinflusst sowie ein erhöhten Fachwissenszuwachs ermöglicht. Die gewonnenen Erkenntnisse können die Grundlage für die Entwicklung und Evaluation von good-practice-Ansätzen naturwissenschaftlicher Lernsituationen bilden. Das Unterrichtskonzept Chemie Pur leistet zudem einen Beitrag im Bereich Outdoor Education, um den Antagonismus von Chemie und Natur zu verringern.

    Description: The original 1818 text of Mary Shelley's classic novel, with annotations and essays highlighting its scientific, ethical, and cautionary aspects. Mary Shelley's Frankenstein has endured in the popular imagination for two hundred years. Begun as a ghost story by an intellectually and socially precocious eighteen-year-old author during a cold and rainy summer on the shores of Lake Geneva, the dramatic tale of Victor Frankenstein and his stitched-together creature can be read as the ultimate parable of scientific hubris. Victor, “the modern Prometheus,” tried to do what he perhaps should have left to Nature: create life. Although the novel is most often discussed in literary-historical terms—as a seminal example of romanticism or as a groundbreaking early work of science fiction—Mary Shelley was keenly aware of contemporary scientific developments and incorporated them into her story. In our era of synthetic biology, artificial intelligence, robotics, and climate engineering, this edition of Frankenstein will resonate forcefully for readers with a background or interest in science and engineering, and anyone intrigued by the fundamental questions of creativity and responsibility. This edition of Frankenstein pairs the original 1818 version of the manuscript—meticulously line-edited and amended by Charles E. Robinson, one of the world's preeminent authorities on the text—with annotations and essays by leading scholars exploring the social and ethical aspects of scientific creativity raised by this remarkable story. The result is a unique and accessible edition of one of the most thought-provoking and influential novels ever written. Essays by Elizabeth Bear, Cory Doctorow, Heather E. Douglas, Josephine Johnston, Kate MacCord, Jane Maienschein, Anne K. Mellor, Alfred Nordmann

    Description: When auralizing moving sound sources in Virtual Reality (VR) environments, the two main input parameters are the location and radiated signal of the source. An array measurement-based model is developed to characterize moving sound sources regarding the two parameters in this thesis. This model utilizes beamforming, i.e. delay and sum beamforming (DSB) and compressive beamforming (CB) to obtain the locations and signals of moving sound sources. A spiral and a pseudorandom microphone array are designed for DSB and CB, respectively, to yield good localization ability and meet the requirement of CB. The de-Dopplerization technique is incorporated in the time-domain DSB to address moving source problems. Time-domain transfer functions (TDTFs) are calculated in terms of the spatial locations within the steering window of the moving source. TDTFs then form the sensing matrix of CB, thus allowing CB to solve moving source problem. DSB and CB are further extended to localize moving sound sources, and the reconstructed signals from the beamforming outputs are investigated to obtain the source signals. Moreover, localization and signal reconstruction are evaluated through varying parameters in the beamforming procedures, i.e. steering position, steering window length and source speed for a moving periodic signal using DSB, and regularization parameter, signal to noise ratio (SNR), steering window length, source speed, array to source motion trajectory and mismatch for a moving engine signal using CB. The parameter studies show guidelines of parameter selection based on the given situations in this thesis for modeling moving source using beamforming. Both algorithms are able to reconstruct the moving signals in the given scenarios. Although CB outperforms DSB in terms of signal reconstruction under particular conditions, the localization abilities of the two algorithms are quite similar. The practicability of the model has been applied on pass-by measurements of a moving loudspeaker using the designed arrays, and the results can match the conclusions drawn above from simulations. Finally, a framework on how to apply the model for moving source auralization is proposed.

    Description: Neuere Erkenntnisse zum Umsatzverhalten an Dieseloxidationskatalysatoren (DOCs) zeigen, dass das Umsatzverhalten von Schadstoffen vom Oxidationsgrad der verwendeten Edelmetallkatalysatoren abhängen kann. Dabei wird deutlich, dass sich der Oxidationsgrad bei typischen Abgaszusammensetzungen langsam und reversibel mit der Katalysatortemperatur ändert. Das kann bei periodischen Katalysatortemperaturänderungen zu einem ausgeprägten Hystereseverhalten führen. Bisherige Ergebnisse liegen insbesondere zum Verhalten der NO-Oxidation an Platin-Katalysatoren vor. Ziel der vorliegenden Arbeit ist es daher, die Untersuchungen auf seriennahe Pd- und PtPd-Mischkatalysatoren sowie auf andere abgastypische Schadstoffe, wie CO und Kohlenwasserstoffe, zu erweitern und dabei auch den Einfluss der Katalysatoralterung zu erfassen. Es wurde ein globalkinetisches Modell entwickelt und an die experimentellen Befunde angepasst. Dabei zeigte sich, dass es in der Regel möglich ist, das Umsatzverhalten bei reinen Pt- und Pd-Katalysatoren mit diesem örtlich eindimensionalen, makrokinetischen Zweiphasenmodell zutreffend zu beschreiben, wohingegen das Verhalten auf Pt/Pd-Mischkatalysatoren weniger gut simuliert werden kann. Dies ist vermutlich auf die heterogene Struktur der Pt/Pd-legierten Partikel zurückzuführen.

    Description: Nanofibers, particularly those of a carbonaceous content, have received increased interest in the past two decades due to their outstanding physico-chemical characteristics and their possibility to form and contribute towards a plethora of potentially advantageous materials for consumer, industrial and medical applications. Despite this, and together with the numerous research studies and published articles that have sought to investigate these aspects, the potential impact of CNTs is still not understood. Whether or not nanofibers may be able to provide a sophisticated alternative to conventional materials is still debatable, whilst their effects upon both environmental and human health are highly equivocal. How nanofibers are conceived can determine how they may interact with different environments, such as the human body. Understanding each key step of the synthesis and production of nanofibers to their use within potential applications is therefore essential in gaining an insight into how they may be perceived by any biological system and environment. Thus, obtaining such information will enable all scientific communities to begin to realize the potential advantages posed by nanofibers. The aim of this Special Issue therefore, was to provide a collective overview of nanofibers; ‘from synthesis to application’. The Issue particularly focuses upon carbon-based nanofibers, but also highlights alternative nanofiber types. Emphasis is given holistically, with articles discussing the production routes of nanofibers, their plight during their life-cycle (origin to applied form and effects over time), as well as how nanofibers could either incite conflict, or provide aid to human and environmental health.

    Description: This volume, occasioned by the centenary of the Fritz Haber Institute, formerly the Institute for Physical Chemistry and Electrochemistry, covers the institute's scientific and institutional history from its founding until the present. The institute was among the earliest established by the Kaiser Wilhelm Society, and its inauguration was one of the first steps in the development of Berlin-Dahlem into a center for scientific research. Its establishment was made possible by an endowment from Leopold Koppel, granted on the condition that Fritz Haber, well-known for his discovery of a method to synthesize ammonia from its elements, be made its director. The history of the institute has largely paralleled that of 20th-century Germany. It undertook controversial weapons research during World War I, followed by a "Golden Era" during the 1920s, in spite of financial hardships.

    Description: Die Chemie büßt zugunsten physikalischer und lebenswissenschaftlicher Konzeptionen zunehmend an Deutungsmacht über die molekulare Welt ein. Sandra Lang untersucht, inwiefern die Ausdifferenzierung der chemischen Wissenschaften mit sich ebenfalls ausdifferenzierenden Zugriffen auf das Molekulare zusammenhängt. Anhand der vier exemplarischen Grenzfelder Materialwissenschaften, Biomedizin, Pharmazie und Quantenchemie und deren Narrative zur molekularen Eigenschaft der Chiralität veranschaulicht sie die transformative Phase der Chemie angesichts sich wandelnder Innovationsdispositive.

    Description: This document, which is directed at the fishing sector, researchers, conservationists and fishery administrators, was developed by researchers who are members of the Specialists Group for Marine Turtle Research and conservation in the Southwestern Atlantic Ocean (SWA) in response to the urgent need to evaluate the impact generated on sea turtles by fisheries. Historically, sea turtle conservation efforts have focused almost exclusively on the protection of nesting beaches. Nevertheless, over the last decade, research has proved incidental mortality as a result of fishing activities to be one of the greatest threats to these animals. This type of interaction is not only problematic for turtles, but also generates financial losses for fishermen and businesses. In spite of the efforts that are currently underway, researchers still do not have a detailed understanding of the impact that bycatch produces on sea turtle populations in the SWA. We have a long way to go before its effects can be minimized. Further research is needed regarding the biology and ecology of the various turtle species as well as the effective application of mitigation measures. The life cycles of sea turtles are long and complex. Turtles occupy various ecosystems (nesting beaches, coastal, neritic and oceanic zones, as well as pelagic and demersal areas) throughout their lifetimes, transcending various Exclusive Economic Zones and International Waters. The five species that inhabit the SWA region perform vast feeding and reproductive migrations, traveling through areas where many different fishing fleets operate. Therefore, sea turtles in the SWA interact with virtually all fisheries. These circumstances make it necessary to carry out biological, fishing related and conservation studies on a regional level. The efficiency of the existing international and national legal instruments has yet to be determined, in terms of their effectiveness in protecting sea turtles. In some cases, legislation that is specifically related to the interaction between fisheries and turtles does exist, such as those laws requiring the mandatory use of turtle excluding devices (TEDs). There are also explicit bans on sea turtle capture. Nevertheless, none of these regulations prevent sea turtle bycatch. Although some regional legal instruments are needed, these and the existing legislation will only be effective if they are accompanied by a broader range of permanent education and control measures, to achieve the commitment of all the parties involved. The ecosystem approach is gaining popularity among fishery administration organizations. Research and conservation efforts should also be moving in that direction. A regional and international effort is required in order to compile information regarding the bycatch produced by the various types of fisheries and fleets operating in the area. The enormous increase in fishing pressure that these fleets are exerting in this area has not been accompanied by an increase in information regarding the bycatch of species that have no commercial value. Pelagic longlining is one of the fishing methods, which must be most closely monitored, due to the high levels of bycatch that it produces, as well its ample distribution throughout the region, and the high level of fishing effort that it accounts for. Coastal trawlers and gillnetters must also be considered critical players, because they too produce a large rate of bycatch. These are the three types of fisheries that are most broadly distributed throughout the region, accounting for the majority of the fishing effort. Most of the institutions that work toward sea turtle conservation in the area have only begun to address the issue of bycatch over the last decade. This timeframe is reflected in the scope and quantity of the available publications, as well as the progress of activities directed at mitigating this problem. All of the institutions that have been mentioned in this report have made the gathering of information regarding interaction between sea turtles and fisheries one of their top priorities. Some institutions are even developing working programs for monitoring fisheries and testing mitigation measures. Many of these institutions have managed to develop adequate relationships with fishermen, ship owners and administrators. Nevertheless, limited access to funding is an obstacle to the development and testing of mitigation measures. The SWA network, which is a very valuable instrument that was created in 2003, has allowed the region’s institutions and researchers to exchange information and share their experience, in addition to lending each other support in carrying out joint activities, thus strengthening sea turtle conservation efforts. The capacity demonstrated so far by the region’s researchers and institutions, testifies to their ability to continue to make progress in knowledge generation and tests of bycatch mitigation measures.

    Description: Este documento, dirigido al sector pesquero, investigadores, conservacionistas y administradores de las pesquerías, surge como respuesta de investigadores pertenecientes al Grupo de Especialistas en Investigación y Conservación de Tortugas Marinas en el Atlántico Sud Occidental (ASO) a la urgente necesidad de evaluar el impacto de las pesquerías sobre las tortugas marinas. Históricamente, los esfuerzos referidos a la conservación de las tortugas marinas se han dirigido casi exclusivamente a proteger las playas de anidación. Sin embargo en la última década se ha podido comprobar que una de las mayores amenazas es la mortalidad incidental causada por las pesquerías. Esta interacción no implica únicamente un problema para las tortugas, sino que también genera pérdidas económicas para los pescadores y las empresas.

    Description: El presente trabajo llama la atención a las recientes epidemias de intoxicación histamínicas reportadas en los Estados Unidos, debido al consumo del dorado (Coryphaena hippurus) o Mahi-Mah, contaminado. Esto dió como resultado la prohición de las importaciones de esta especie, proveniente de varios países entre ellos el Ecuador, y siendo el dorado una especie de relativa importancia económica en este país, dicha prohibición ha preocupado al sector pesquero. Los estudios llevados a cabo muestran claramente la susceptibilidad de esta especie a desarrollar histamina. Esto se debe principalmente a la temperatura a la que está expuesta, pues la demora antes de enhielar el pescado es la etapa crítica. Los resultados muestran un aumento exponencial de los niveles de histamina, en ciertos casos después de tan solo 9 horas de almacenaje a temperaturas ambientales entre 25-30°C. Los niveles de histamina en pescado muestreado en el mercado local fueron tan altos como 250 mg/100g de muestra. Se demuestra que el problema se debe fundamentalmente al mal manejo de la captura por parte de la flota artesanal, y la subsecuente falta de infraestructura adecuada para conservarla, es decir, no se enfría el pescado. Sin embargo, el estudio muestra que una reducción de la temperatura del pescado de solo 15° menos, podría dar como resultado un producto de mayor calidad. En el presente trabajo se hacen recomendaciones para establecer un nivel máximo permitido para la exportación de 10 mg%, y se comparan dos métodos rápidos de análisis.

    Description: 153 experimental sets were made with stackable Antillean fish traps in depths of 5 to 30 m in the waters around the Galápagos Island (Ecuador), between Octobre and April 1983. 1,885 fish were caught of 18 species mainly of the families Pomadasyidae, Acanthuridae, Sparidae and Serranidae. The mean catch rate was 5,5 Kg per lift or 0,4 Kg.h-1, and the mean weight of the fish caught was 0,45 Kg. The optimum set duration was found to be between 2 and 18 hours (possibly indicating a high rate of escape). This study took place during the period of the ”El Niño”, when catches of fish in this area generally were low, and it is not known what effect this had. The catches were good compared with other shallow areas, but the fishes caught were mainly of medium quality. It is thought that significant increases in the quantity and quality of the catch could be obtained with commercial traps in deeper areas, but the efficient use of these would require new vessels and equipment, and the resulting increase in fishing effort could lead to overfishing of the most acceptable species of reef fish. Hence the development of fishery using fish traps is not recommended for Galápagos. A study of the biology of the fish caught was carried out. A bibliography of references on fish traps and their use was compiled and is included.

    Description: Le domaine maritime sénégalais s’étend de 18°00 N, -20°00 W, -16°30 E, 12°15 S ; la presqu’île du Cap-Vert située entre 14°30 N et 15°00 N le divise en deux zones aux caractéristiques topographiques distinctes. Au nord, le plateau continental est peu étendu vers le large et orienté Nord-Nord/Est. Au sud de la presqu’île, le plateau s’élargit et le talus continental est orienté nord-sud. L’embouchure du fleuve Sénégal au Sénégal au Nord de la presqu’île du Cap-Vert et celles de la Gambie et de la Casamance au Sud constituent également un trait marquant de cette région. Les travaux réalisés au Sénégal en océanographie ont montré : - l’existence de deux saisons marines aux caractéristiques très différentes qui se succèdent : une saison chaude de juillet à octobre et une saison froide de décembre à mai. Ces deux saisons sont séparées par des périodes de transition. Pendant la saison froide, les alizés (vent de secteur nord-ouest à nord-est) s’établissent et engendrent à la côte une résurgence d’eau profonde (upwelling) vers la surface ; - la mise en évidence de systèmes de grands courants aux caractéristiques différentes : le courant des Canaries et le contre courant équatorial ; - la description de trois grandes houles au large du Sénégal : o la houle de Nord-Nord ouest qui a lieu toute l’année o la houle de Sud-Sud ouest apparaissant pendant l’hivernage o la houle d’ouest possible aux environs du mois de novembre. Le littoral sénégalais représente une zone d’intérêt stratégique à la fois sur le plan démographique, économique et environnemental. Les milieux naturels, dans un état de conservation relativement préservé, produisent des ressources vitales pour les 11 millions d’habitants peuplant le Sénégal. L’économie nationale sénégalaise est très dépendante de ces ressources côtières et marines qui constituent les principales recettes en devises, qu’il s’agisse de pêche ou de tourisme. L’analyse de la situation et des tendances montre que la zone côtière fait l’objet de pressions diversifiées et de plus en plus lourdes. Ces pressions se traduisent souvent par des conflits d’intérêts entre les différents secteurs et par des impacts qui génèrent une dégradation de l’environnement et des conditions de vie des populations. Cette évolution risque ainsi de compromettre les potentialités de développement offertes par les 700 Km de littoral sénégalais. La pression démographique se développe préférentiellement sur la zone côtière qui accueille déjà près de 60% des habitants, notamment dans les centres urbains et les capitale, toutes situées en bord de mer, et qui continuent à recevoir des populations en provenance de l’intérieur, réfugiés climatiques ou économiques, ou simplement jeunesse attirée par les « lumières de la ville ». Cet exode, à l’origine de dysfonctionnements des systèmes de production ruraux qui manquent peu à peu de main d’oeuvre, contribue à son tour à générer des perturbations au niveau des centres urbains où la misère se substitue parfois à la pauvreté.
    Description: Les besoins en matériaux de construction consécutifs à cette évolution démographique entraînent des prélèvements massifs de sable sur les plages qui ont à leur tour des conséquences négatives sur l’érosion et la protection du littoral. La fragilisation des cordons dunaires augmente ainsi les risques d’inondations des terres, la ville de Saint Louis étant particulièrement vulnérable à cet égard. Les besoins en développement ont conduit à la réalisation d’infrastructures le long du littoral. Ces constructions, qui tiennent trop rarement compte des contraintes environnementales, ont entraîné des répercussions structurelles sur l’équilibre de la zone côtière. Ainsi, les barrages anti-sel, tel le barrage de Diama sur le fleuve Sénégal, ont entraîné des répercussions sur le fonctionnement de certains écosystèmes côtiers. En condamnant les influences des apports d’eau douce ils appauvrissent les milieux situés en aval, stérilisant peu à peu des zones riches en ressources ainsi que les économies et les cultures qui en dépendent. Le ralentissement des courants et la baisse de salinité en amont du barrage favorisent l’apparition de certaines plantes envahissantes, telles que la bilharziose ou le paludisme. Les effectifs de poissons dépendant de milieux à salinité variable sont directement affectés, expliquant par exemple une chute de près de 70% des captures dans le bas delta du Sénégal. Les besoins du développement se traduisent également par l’amélioration ou la création d’axes routiers qui, dans la majorité des cas, longent la zone côtière. Ces ouvrages entraînent des impacts directs sur l’environnement, tels la destruction des mangroves là où les routes barrent l’écoulement des marées (exemple de la route Samba Dia – Djifère. Les systèmes de production traditionnels sont en règle générale peu préparés à faire face à des circuits de commercialisation organisés à une échelle régionale ou internationale, où à des technologies plus performantes, et éprouvent des difficultés à maintenir un contrôle sur leur terroir. Faute de pouvoir opérer une métamorphose rapide de leur système de production, le risque existe de voir peu à peu disparaître des savoir-faire d’une grande valeur dans la gestion même de ces territoires et de leurs ressources et , plus généralement, des cultures qui leur sont associées. Le développement industriel exerce des impacts potentiels ou réels de grande magnitude sur la zone côtière et marine. Les secteurs les plus significatifs à cet égard sont le tourisme et les hydrocarbures. Concernant le premier, les infrastructures, principalement orientées vers le tourisme balnéaire, sont en grande majorité installées à proximité directe de la zone côtière. L’absence quasi généralisée d’études d’impacts approfondies et indépendantes a conduit à de nombreux échecs. Ainsi, la plupart des projets ont été pensés et réalisés sans tenir suffisamment compte des contextes socio-économiques, culturels et environnementaux dans lesquels ils s’insèrent. Certaines réalisations ont été planifiées sur des secteurs soumis à une forte érosion littorale, compromettant de façon irrémédiable non seulement les investissements mais l’utilisation ultérieure du site, comme cela s’est produit sur les plages au sud immédiat du Cap Skirring. Les questions relatives à la disponibilité en eau douce qui se posent de façon cruciale dans le Saloum par exemple, à la gestion des déchets et des eaux usées ne sont que rarement prises en considération de façon structurelle et durable, conduisant à la dégradation de l’environnement ou à des conflits avec les communautés locales qui nuisent à la qualité même du tourisme. L’exploration et l’exploitation des ressources en hydrocarbures représentent aussi un secteur d’intérêt stratégique avec une généralisation des prospections. Si la découverte de gisement d’intérêt commercial représente une opportunité majeure pour l’économie nationale, elle soulève néanmoins un certain nombre de questions au regard de l’environnement. En effet les des puits. Parmi ces risques nous pouvons citer les impacts des études sismiques sur les organismes marins, notamment poissons et cétacés, le rejet de fluides toxiques et déblais de forage, le déversement des eaux de production et les pollutions aiguës dues à des accidents intervenant pendant le forage, le stockage ou le transport. Le Sénégal en ce moment, en est au stade de la prospection. Toutefois, pour ce qui concerne le transport d’hydrocarbures, plus de 90 000 0000 de tonnes d’hydrocarbures transitent par les côtes sénégalaises. Les modèles de dérive des nappes élaborés par la Compagnie pétrolière Woodside en relation avec le champ de Chinguetti, actuellement en cours de production au large de la Mauritanie, montrent des probabilités d’impact sur les côtes allant du golfe d’Arguin jusqu’à Dakar, en cas d’accident. La surexploitation des ressources halieutiques constitue également un problème au niveau de l’environnement marin et côtier. En effet, si une partie de la fluctuation des biomasses peut s’expliquer par les changements du régime des upwellings, la baisse des captures s’explique par un effort de pêche excessif, que ce soit dans le sous-secteur industriel ou artisanal. A cette surcapacité vient s’ajouter la présence de flottes illicites non déclarées et non réglementées. L’utilisation de certains engins ou pratiques de pêche contribue à aggraver la situation : la pêche crevettière est à l’origine de prises accidentelles qui représentent jusqu’à 85 % du total des captures, incluant des espèces protégées comme les tortues marines, et qui sont rejetés à la mer . Les chaluts de fonds, qui vont pêcher jusqu’à 800 m de profondeur, ainsi que les dragues à coquillages entraînant des dégâts structurels sur les écosystèmes De plus l’influence des marchés à l’exportation exerce des pressions sélectives sur certaines espèces, les espèces démersales de poissons, céphalopodes étant les plus recherchées sur le marché. Les changements climatiques ont également des impacts négatifs sur l’environnement marin et côtier. On sait que l’élévation du niveau marin aura des répercussions directes sur les installations humaines littorales ainsi que sur les écosystèmes insulaires et côtiers. Des zones de mangroves entières qui ne disposent pas des conditions écologiques pour s’adapter peuvent disparaître, entraînant des risques accrus d’érosion et d’inondation. Ces mêmes risques se multiplient avec la fréquence accrue des épisodes météorologiques exceptionnels tels que les ondes de tempêtes capables de drosser les pirogues à la côte ou de provoquer la rupture de cordons dunaires. On sait par ailleurs que le réchauffement de la température des mers influe négativement sur la productivité des océans et la dynamique des courants tels que le courant profond originaire de l’antarctique et qui exporte vers le Sénégal et les autres pays de la sousrégion des sels nutritifs présents dans les upwellings. On observe également une diminution de la puissance des alizés qui pourrait avoir des répercussions directes sur la force des upwellings et donc sur la productivité des pêcheries et du milieu marin en général. La stratégie de réponse proposée combine une protection des zones côtières importantes et un reboisement des dunes littorales dans les secteurs de la côte nord et de la Flèche de Sangomar particulièrement menacés. L’évaluation économique de cette stratégie montre qu’elle est coûteuse mais nettement en deçà de la valeur économique des terres qu’elle sera amenée à protéger. Des efforts complémentaires devront cependant être faits pour évaluer le coût d’autres solutions de protection telles que le nourissement artificiel des plages. Par ailleurs, la stratégie envisagée ne répondant qu’à l’un des impacts des changements climatiques, à savoir les inondations, toute une série de mesures dites d’accompagnement ont été suggérées qui visent à diminuer la vulnérabilité en gérant mieux les ressources présentes dans la zone côtière, en développant les techniques de récupération des sols salés et en prenant des mesures législatives et institutionnelles appropriées. Enfin, il est très important de souligner que ces différentes mesures ne devraient être envisagées que dans un cadre plus global de gestion intégrée des zones côtières, seul à même d’assurer la participation de l’ensemble des acteurs concernés, l’éducation, la recherche et l’information environnementales mais aussi la cohérences et le suivi des mesures.

    Description: This paper examines the arrival of a new group of fishermen on the Kenyan coast and what this has meant for the state of fishery resources. It reviews four subject areas: access and the number of fishermen; the fishermen’s identity; the choice of fishing gear; and the fishing grounds selected. Data were collected from a small number of fishing households in the villages of Uyombo and Takaungu in Kilifi District, using mainly qualitative research methods. Local households on the Kenyan coast face increasing pressure on land as well as on marine resources. The declining economic situation and greater pressure on land have made people turn to fishing as an income-generating activity. This group of fishermen is referred to as the ‘new’ generation of fishermen as they have been involved in fishing for only one or two generations (including the current one) in contrast to the ‘old’ generation from families who have been fishing or in fishingrelated activities for much longer. The old generation of fishermen and their households have also diversified their incomes, with many fishing households turning to farming, for example, with women and grown-up children involved in various activities. The new generation of fishermen, mainly of the Mijikenda population group, has often been blamed for the loss of traditional access regulations and for using harmful fishing gear. This paper discusses the new generation of fishermen and their identity as they perceive it and relates this to employment generation as a policy measure for marine conservation.

    Description: The management and conservation of the world's oceans require synthesis of spatial data on the distribution and intensity of human activities and the overlap of their impacts on marine ecosystems. We developed an ecosystem-specific, multiscale spatial model to synthesize 17 global data sets of anthropogenic drivers of ecological change for 20 marine ecosystems. Our analysis indicates that no area is unaffected by human influence and that a large fraction (41%) is strongly affected by multiple drivers. However, large areas of relatively little human impact remain, particularly near the poles. The analytical process and resulting maps provide flexible tools for regional and global efforts to allocate conservation resources; to implement ecosystem-based management; and to inform marine spatial planning, education, and basic research.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Halpern, Benjamin S -- Walbridge, Shaun -- Selkoe, Kimberly A -- Kappel, Carrie V -- Micheli, Fiorenza -- D'Agrosa, Caterina -- Bruno, John F -- Casey, Kenneth S -- Ebert, Colin -- Fox, Helen E -- Fujita, Rod -- Heinemann, Dennis -- Lenihan, Hunter S -- Madin, Elizabeth M P -- Perry, Matthew T -- Selig, Elizabeth R -- Spalding, Mark -- Steneck, Robert -- Watson, Reg -- New York, N.Y. -- Science. 2008 Feb 15;319(5865):948-52. doi: 10.1126/science.1149345.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Center for Ecological Analysis and Synthesis, 735 State Street, Santa Barbara, CA 93101, USA. halpern@nceas.ucsb.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18276889" target="_blank"〉PubMed〈/a〉

    Description: Atlantic bluefin tuna populations are in steep decline, and an improved understanding of connectivity between individuals from eastern (Mediterranean Sea) and western (Gulf of Mexico) spawning areas is needed to manage remaining fisheries. Chemical signatures in the otoliths of yearlings from regional nurseries were distinct and served as natural tags to assess natal homing and mixing. Adults showed high rates of natal homing to both eastern and western spawning areas. Trans-Atlantic movement (east to west) was significant and size-dependent, with individuals of Mediterranean origin mixing with the western population in the U.S. Atlantic. The largest (oldest) bluefin tuna collected near the northern extent of their range in North American waters were almost exclusively of western origin, indicating that this region represents critical habitat for the western population.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rooker, Jay R -- Secor, David H -- De Metrio, Gregorio -- Schloesser, Ryan -- Block, Barbara A -- Neilson, John D -- New York, N.Y. -- Science. 2008 Oct 31;322(5902):742-4. doi: 10.1126/science.1161473.
