اعلم أن المرارة كيس معلّق من الكبد إلى ناحية المعدة من طبقة واحدة عصبانية ولها ضمّ إلى الكبد ومجرى فيه يجذب الخلط الرقيق الموافق لها والمرار الأصفر ويتصل هذا المجرى بنفس الكبد والعروق التي فيها يتكون الدم وله هناك شعب كثيرة غائصة وإن كان مدخل عمودها من التقعير والفم ومجرى إلى ناحية المعدة‏.‏ والأمعاء ترسل فيه إلى ناحيتهما فضل الصفراء على ما ذكرناه في الكتاب الأول‏.‏ وهذا المجرى يتصل أكثر شعبه بالاثني عشري وربما اتصل شيء صغير منه بأسفل المعدة وربما وقع الأمر بالضد فصار الأكبر المتصل بالوعاء الأغلظ إلى أسفل المعدة والأصغر إلى الاثني عشري‏.‏ وفي أكثر الناس هو مجرى واحد متصل بالاثني عشري‏.‏ وأما مدخل الأنبوبة المصاصة للمرارة في المرارة فقريب من مدخل أنبوبة المثانة في المثانة‏.‏ ومن عادة الأطباء الأقدمين أن يسموا المرار الكيس الأصغر كما أنه من عادتهم أن يسموا المثانة الكيس الأكبر ومن المنافع في خلقة المرارة تنقية الكبد من الفضل الرغوي وأيضاً تسخينها كالوقود تحت القدر وأيضاً تلطيف الدم وتحليل الفضول وأيضاً تحريك البراز وتنظيف الأمعاء وشدّ ما يسترخي من العضل حوله وإنما لم يخلق في الأكثر للمرارة سبيل إلى المعدة لتغسل رطوباتها بالمرة كما تغسل بها في رطوبات الأمعاء لأن المعدة تتأذى بذلك وتغثّي ويفسد الهضم فيها بما يخالط الغذاء من خلط رديء ويأتيها من العرق الضارب‏.‏ وللعصبة التي تتصل بالكبد شعبتان صغيرتان جداً والمرارة كالمثانة طبقة واحدة مؤلفة من أصناف الليف الثلاثة وإذا لم تجذب المرارة المرار أو جذبت فلم تستنق عنه حدثت آفات فإن الصفراء إذا احتبست فوق المرارة أو رمت الكبد وأورثت اليرقان وربما عفنت وأحدثت حميات رديئة‏.‏ وإذا سالت إلى أعضاء البول بإفراط قرحت وإذا سالت إلى عضو ما أحدثت الحمرة والنملة وإذا دبت في البدن كله ساكنة غير هائجة أحدثت اليرقان وإذا سالت عن المرارة إلى الأمعاء بإفراط أورثت الإسهال المراري والسحج‏.‏  

Diversity and Interaction in a Temperate Forest Community: Ogawa Forest Reserve of Japan (Ecological Studies #158)

by Dr

The studies in the Ogawa Forest Reserve (OPR) were initiated by a group of plant ecologists and gradually expanded into a comprehensive project covering various aspects of biology, soil science, and silviculture. The project was integrated as part of the Forest Ecosystem Team under the BIO-COSMOS Program funded by the Ministry of Agriculture, Forestry and Fisheries. As the coordinators of the Forest Ecosystem Team, we are pleased that reports of the long-term studies carried out in the OFR are being published in this first volume on Japanese ecosystems in the Ecological Studies series. Scientists and researchers have made numerous contributions to the field of forest ecology during more than 10 years of studies in the OFR. Two reasons can be cited for the success of the project: scientists from various disciplines concen­ trated on a single target forest ecosystem, and the research continued over a rela­ tively long term. It is now recognized that ecological processes include compli­ cated mechanisms supported by interactions among organisms and large temporal variations. The researchers in the OFR project were motivated by their interest in the history of ecosystems and the interactions of diverse creatures in the forest.

Small Firms and Entrepreneurship in Central and Eastern Europe: A Socio-Economic Perspective (Technology, Innovation and Policy (ISI) #14)

by Dr

Much of the research on transformation/transition in Central and Eastern European Countries (CEECs) focuses on macroeconomic issues (inflation, economic growth, employment ...). Little research has been devoted so far to microeconomic analysis. Recently the issue of new enterprises and firm founders has moved to the centre of economic and policy considerations. Readers of this book will learn about the role played by these firms in the transformation of central and eastern European countries. The book also includes contributions from Central and Eastern Europe on which little or no investigation has been performed until now (Yugoslavia, Romania, Slovakia).

Modern Methods of Drug Discovery (Experientia Supplementum #93)

by Dr Prof.

Research in the pharmaceutical industry today is in many respects quite different from what it used to be only fifteen years ago. There have been dramatic changes in approaches for identifying new chemical entities with a desired biological activity. While chemical modification of existing leads was the most important approach in the 1970s and 1980s, high-throughput screening and structure-based design are now major players among a multitude of methods used in drug discov­ ery. Quite often, companies favor one of these relatively new approaches over the other, e.g., screening over rational design, or vice versa, but we believe that an intelligent and concerted use of several or all methods currently available to drug discovery will be more successful in the medium term. What has changed most significantly in the past few years is the time available for identifying new chemical entities. Because of the high costs of drug discovery projects, pressure for maximum success in the shortest possible time is higher than ever. In addition, the multidisciplinary character of the field is much more pronounced today than it used to be. As a consequence, researchers and project managers in the pharmaceutical industry should have a solid knowledge of the more important methods available to drug discovery, because it is the rapidly and intelligently combined use of these which will determine the success or failure of preclinical projects.

Physical and Chemical Aspects of Organic Electronics: From Fundamentals to Functioning Devices

by Christof W 246 Ll

Organic molecules are currently being investigated with regard to their application as active components in semiconductor devices. Whereas devices containing organic molecules for the generation of light - organic light emitting diodes (OLED) - have already reached the market (they e.g. display information on mobile phones), transistors where organic molecules are used to actively control currents and voltages are still in the development stage. In this book the principle problems related to using organic materials as semiconductors and to construct functioning devices will be addressed. A particular emphasis will be put on the difference between inorganic semiconductors such as Si, Ge and GaAs and organic semiconductors (OSC). The special properties of such soft matter require particular approaches for processing characterization and device implementation, which are quite different from the approach used for conventional semiconductors.

Teaching Fundamental Concepts of Informatics: 4th International Conference on Informatics in Secondary Schools - Evolution and Perspectives, ISSEP 2010, Zurich, Switzerland, January 13-15, 2010, Proceedings (Lecture Notes in Computer Science #5941)

by Juraj Hromkovi 269 Rastislav Královic Jan Vahrenhold

The International Conference on Informatics in Secondary Schools: Evolution and Perspective (ISSEP) is an emerging forum for researchers and practitioners in the area of computer science education with a focus on secondary schools. The ISSEP series started in 2005 in Klagenfurt, and continued in 2006 in Vilnius, and in 2008 in Torun. ´ The 4th ISSEP took part in Zurich. This volume presents 4 of the 5 invited talks and 14 regular contributions chosen from 32 submissions to ISSEP 2010. The ISSEP conference series is devoted to all aspects of computer science teaching. In the preface of the proceedings of ISSEP 2006, Roland Mittermeir wrote: “ISSEP aims at educating ‘informatics proper’ by showing the beauty of the discipline, hoping to create interest in a later professional career in c- puting, and it will give answers di?erent from the opinion of those who used to familiarize pupils with the basics of ICT in order to achieve computer lit- acy for the young generation. ” This is an important message at this time, when several countries have reduced teaching informatics to educating about current softwarepackagesthatchangefromyeartoyear. ThegoalofISSEPistosupport teaching of the basic concepts and methods of informatics, thereby making it a subject in secondary schools that is comparable in depth and requirements with mathematics or natural sciences. As we tried to present in our book “Algori- mic Adventures.

Routledge Handbook of Energy Economics (Routledge International Handbooks)

by U 287 Ur Soyta 351 Ramazan Sar 305

Energy consumption and production have major influences on the economy, environment, and society, but in return they are also influenced by how the economy is structured, how the social institutions work, and how the society deals with environmental degradation. The need for integrated assessment of the relationship between energy, economy, environment, and society is clear, and this handbook offers an in-depth review of all four pillars of the energy-economy-environment-society nexus. Bringing together contributions from all over the world, this handbook includes sections devoted to each of the four pillars. Moreover, as the financialization of commodity markets has made risk analysis more complicated and intriguing, the sections also cover energy commodity markets and their links to other financial and non-financial markets. In addition, econometric modeling and the forecasting of energy needs, as well as energy prices and volatilities, are also explored. Each part emphasizes the multidisciplinary nature of the energy economics field and from this perspective, chapters offer a review of models and methods used in the literature. The Routledge Handbook of Energy Economics will be of great interest to all those studying and researching in the area of energy economics. It offers guideline suggestions for policy makers as well as for future research.

Drug Delivery with Targeted Nanoparticles: In Vitro and In Vivo Evaluation Methods

by Y 305 Lmaz Çapan Adem Sahin Hayrettin Tonbul

Nanotechnology has the potential to change every part of our lives. Today, nanotechnology-based products are used in many areas, and one of the most important areas is drug delivery. Nanoparticulate drug delivery systems not only provide controlled delivery of drugs and improved drug solubility but also improve drug efficiency and reduce side effects via targeting mechanisms. However, compared with conventional drug delivery systems, few nanoparticle-based products are on the market and almost all are nontargeted or only passively targeted systems. In addition, obtaining targeted nanoparticle systems is quite complex and requires several evaluation mechanisms. This book discusses the production, characterization, regulation, and currently marketed targeted nanoparticle systems in a broad framework. It provides an overview of targeted nanoparticles’ (i) in vitro characterization, such as particle size, stability, ligand density, and type; (ii) in vivo behavior for different targeting areas, such as tumor, brain, and vagina; and (iii) current advances in this field, including clinical trials and regulation processes.

Advances in Environmental Engineering Research in Poland

by Ma 322 Gorzata Paw 322 Owska Lucjan Paw 322 Owski

A side-effect of numerous anthropogenic activities involves unfavourable changes in the natural environment. The acquisition of natural resources, especially fossil fuels, solid waste and wastewater production, as well as emission of gases and particulate matter from industrial plants and means of transport contribute to disturbances in the natural cycles of elements between different parts of the environment. Local changes lead to global effects, changing the composition of atmosphere, its capacity for absorbing the infrared radiation and temperature, which has further repercussions in the form of weather anomalies, melting glaciers, flooding, migration or extinction of species, social problems, etc. These global changes can be mitigated by local remedial actions, simultaneously taken all over the world, including Poland. Only the joint efforts of communities from different countries can be successful in preserving the world as we know it for the future generations. Realisation of this task requires the cooperation of experts across many fields of science, environmental engineering being one of most relevant. It comprises the engineering actions taken to preserve the balance of the natural environment or restore it if degradation has occurred. This monograph presents several key issues related to the actions aimed at mitigating the negative impact on the environment connected with the acquisition and transport of energy, management of municipal and industrial wastes, as well as the impact of the industry on the aquatic and soil environment. This book is dedicated to academics, engineers, and students involved in environmental engineering, who are following the advances in the research on environmental aspects of energy production and waste management.
