عمدة الطبيب في معرفة النبات

by يحيى مراد

دراسة التراث وتاريخ العلوم عند العرب والمسلمين، أمر لابدّ منه في مرحلة التحوّل التي تمر بها الأمة العربية. ذلك لأن اطلاع أبنائها على المنجزات العلمية التي حققها الأجداد في الماضي، لابدّ أن يكون باعثاً على الثقة في النفوس، وحافزاً لحث الخطى في طريق التقدم العلمي والتقني الذي نسعى لتحقيقه.‏ ومن واجب التراث علينا أن نتصدى بأنفسنا لكشف مكنوناته، ونشر روائعه، وإلقاء الضوء على مدى مساهمته في إغناء المعرفة والعلم خلال قرون عديدة، بعد أن ظل هذا العمل مقتصراً على المستشرقين الذين ينتمون إلى أمم مختلفة.‏ وفي مكتباتنا العربية العامة والخاصة كثير من المخطوطات القيّمة، والكتب النافعة التي لم تدرس حتى الآن، ولاسيّما في موضوع الطب والصيدلة وعلم النبات والتي كان لها سماتها، فأدت دوراً كبيراً في إثراء العلوم وبث روح الحياة. حيث كان يلتقي النبات والدواء في مسيرة واحدة لتأمين الغذاء النافع والدواء الناجع.‏ لقد توافرت للعرب ثروة معرفيّة ولغويّة هائلة حين انصرفوا إلى الطبيعة، كغيرهم من الأمم التي سبقتهم، فوجدوا أن الأرض تزخر بالخيرات، من شجر وعشب وبقل وتابل وغذاء، فانصرفوا إلى "علم الفلاحة" ودراسة النباتات. وألّفوا في ذلك كتباً كثيرة لها أهميتها في ميادين علوم النبات والصيدلة والطب وغيرها.‏ وكانت عنايتهم بأصناف النبات نابعة من حاجتهم إلى الغذاء والدواء معاً. وإلى التطيب بالعطور، وصناعة الصباغة والدباغة، وتركيب المواد الصيدلانية من جذور وقشور وثمار وبذور وأعشاب نباتات مختلفة.‏ وهكذا أصبحت المعاجم العربية، والمؤلفات العلمية، غنية بكم وافر من الأسماء والمصطلحات النباتية، وضمَّت معارف العرب المسلمين القدماء في علمي الطب والنبات. فكانت مصدراً لمن ألف وكتب في المفردات النباتية والغذائية والدوائية. وهي كثيرة العدد نذكر منها: "كتاب النبات" لأبي حنيفة الدينوري(1) ت 282هـ-895م)، وكان من أكثر المعاجم جمعاً للمادة، وأعظمها أثراً في معاجم النبات التي ألفت فيما بعد.‏

Electricity Capacity Markets

by Todd S. Aagaard Andrew N. Kleit

Initially created as afterthoughts to competitive electricity markets, capacity markets were intended to enhance system reliability. They have evolved into massive, highly controversial, and poorly understood billion-dollar institutions. Electricity Capacity Markets examines the rationales for creating capacity markets, how capacity markets work, and how well these markets are meeting their objectives. This book will appeal to energy experts and non-experts alike, across a range of disciplines, including economics, business, engineering, public policy, and law. Capacity markets are an important and provocative topic on their own, but they also offer an interesting case study of how well our energy systems are meeting the needs of our increasingly complex society. The challenges facing capacity markets – harnessing market forces for social good, creating networks that manage complexity, and achieving sustainability – are very much core challenges for our twenty-first century advanced industrial society.

Public Participation, Science and Society: Tools for Dynamic and Responsible Governance of Research and Innovation

by Timo Aarrevaara Mikko Rask Saulė Mačiukaitė-Žvinienė Loreta Tauginienė Vytautas Dikčius Kaisa Matschoss Luciano d’Andrea

The field of public participation is developing fast, with phenomena such as citizen science and crowdsourcing extending the resource base of research, stimulating innovation and making science more accessible to the general population. Promoting public participation means giving more weight to citizens and civil society actors in the definition of research needs and in the implementation of research and innovation. As yet, there is limited understanding of the implications of widespread use of public participation and as a result, there is a risk that it will become a burden for research and an obstacle to bridging the gap between research and society. This volume presents the findings of a three-year international study on innovative public participation. The resulting work studies the characteristics and trends of innovative public participation through a global sample of 38 case studies. It provides theoretical generalisations on the dynamics of public participation, suggestions for an evaluation framework and clear empirical examples of how public participation works in practice. Illustrated by best practice cases, the authors identify characteristics which contribute to successful public participation. The book is aimed primarily at scholars and practitioners of public participation, as well as research managers, policy makers and business actors interested in related issues. There is also a secondary market for students and scholars of European governance studies, sociology and political sciences.

Climate Change and the Voiceless: Protecting Future Generations, Wildlife, and Natural Resources

by Randall S. Abate

Future generations, wildlife, and natural resources - collectively referred to as 'the voiceless' in this work - are the most vulnerable and least equipped populations to protect themselves from the impacts of global climate change. While domestic and international law protections are beginning to recognize rights and responsibilities that apply to the voiceless community, these legal developments have yet to be pursued in a collective manner and have not been considered together in the context of climate change and climate justice. In Climate Change and the Voiceless, Randall S. Abate identifies the common vulnerabilities of the voiceless in the Anthropocene era and demonstrates how the law, by incorporating principles of sustainable development, can evolve to protect their interests more effectively. This work should be read by anyone interested in how the law can be employed to mitigate the effects of climate change on those who stand to lose the most.

The Law for Energy Prosumers: The Case of the Netherlands, New Zealand and Colombia

by Daniela Aguilar Abaunza

This book argues that law has a vital role in shaping the electricity system to enable a more active role for consumers in liberalizsed electricity industries. To do that, this book offers a unique legal perspective of the Netherlands, New Zealand and Colombia to help understand some of the current legal approaches to prosumers and therefore the legal challenges and opportunities facing. Law and regulation have the role of creating a level playing field for emerging participants, such as prosumers, to participate and compete in the market together with traditional actors, bringing not only more competition but also representing a more sustainable, environmental and democratic way to supply energy. Furthermore, law and regulation have the role of responding to innovation and creating space for technological advances to procure the changes in the industry without delay. This book examines some of the legal barriers for the raise of energy prosumers. The traditional role of the distributor when responding to increasing distributed generation in the network; prosumers unable to decide to whom they can sell their electricity to; the price of the energy or even whether to participate more actively in demand response programs. A further issue is the lack of clarity about whether small prosumers are entitled to consumer protection rights and legal challenges regarding configuration, access to the network, access to markets and strict unbundling rules for community energy projects. This book provides a clear, analytical, and informed approach to understanding the regulatory framework around energy prosumers. It will appeal to policy makers, lawyers, individuals, business entrepreneurs or communities wanting to engage in energy projects, as well as academics, researchers and students

Earth Apples: The Poetry of Edward Abbey

by Edward Abbey

Poems about love and landscapes by the author of the classic Desert Solitaire, an &“environmentalist, nature writer, novelist and all-around iconoclast&” (The New York Times).

The New York Times called his memoir Desert Solitaire &“deeply poetic&”—and now Earth Apples gives us his actual poetry, in Abbey&’s first and only collection. Whether writing about vast desert landscapes, New York City, or a love of bawdy women, Abbey's verse is eloquent, irreverent, and unapologetically passionate. The poems gathered here, published digitally for the first time, are culled from Abbey&’s journals and give an insightful and unique glance into the mind of this literary legend.
