توضیحاتی در مورد کتاب پیشرفت در تحقیقات تثبیت نیتروژن: مجموعه مقالات پنجمین سمپوزیوم بین المللی تثبیت نیتروژن ، Noordwijkerhout ، هلند ، 28 آگوست - 3 سپتامبر 1983



در مورد چهار سمپوزیوم بین المللی قبلی در مورد تثبیت نیتروژن، که در پولمن، واشنگتن ایالات متحده آمریکا (1974) برگزار شد. سالامانکا، اسپانیا (1976); مدیسون، ویسکانسین، ایالات متحده آمریکا (1978); و کانبرا، استرالیا (1980)، پنجمین سمپوزیوم که از 28 اوت تا 3 سپتامبر 1983 در نوردویکرهوت هلند برگزار شد، از حمایت ژنتیکی آزمایشگاه تحقیقاتی بنیاد چارلز اف. کترینگ و اداره دره تنسی برخوردار شد. این حمایت با ارائه یک انجمن هم برای تبادل ایده ها و هم برای جمع بندی علمی و بحث، همانطور که در 10 سال گذشته در هر یک از چهار کتاب منتشر شده قبلی به تصویر کشیده شده است، به پیشرفت تحقیقات در این زمینه وسیع علم کمک کرده است. با وجود اینکه همه جلسات قبلی با حضور خوبی همراه بود، کنفرانس حاضر بزرگترین کنفرانس تاکنون بوده است. 550 دانشمند از 60 کشور مختلف در "کنفرانس Leeuwenhorst" شرکت کردند و بسیاری از رشته های مختلف را که به طور فعال در تحقیقات در این زمینه درگیر هستند را ارائه کردند: شیمیدانان، بیوشیمی ها، زیست شناسان مولکولی، ژنتیک ها، میکروبیولوژیست ها، فیزیولوژیست های گیاهی، کشاورزان. تعداد زیادی از آنها باید دوران سختی را برای جمع آوری بودجه لازم برای حضور سپری کنند. علاوه بر این، نشست موازی "سیاست گذاران" از آسیای جنوب شرقی، آفریقا و آمریکای جنوبی تحت نظارت موسسه بین المللی Crosscurrents، دیتون، OR، ایالات متحده آمریکا و دانشگاه سازمان ملل متحد، توکیو، ژاپن برگزار شد. این شرکت کنندگان در برخی از جلسات علمی شرکت کردند تا از دیدگاه تعدادی از دانشمندان در سمپوزیوم بهره مند شوند.


توضیحاتی درمورد کتاب به خارجی

As for the preceding four International Symposia on Nitrogen Fixation, held in Pullman, Washington USA (1974); Salamanca, Spain (1976); Madison, Wisconsin, USA (1978); and Canberra, Australia (1980), the 5th Symposium held from August 28 - September 3, 1983 in Noordwijkerhout, The Netherlands, received the gene­ rous support of the Charles F. Kettering Foundation Research Laboratory and the Tennessee Valley Authority. This support has helped research progress in this broad field of science by offering a forum both for the exchange of ideas and for scientific summary and discussion as captured over the last 10 years in each of the four books published previously. Although all previous meetings were well attended, the present conference was the largest so far. 550 scien­ tists from 60 different countries attended the "Leeuwenhorst Conference", re­ presenting the many different disciplines actively involved in research in this field: chemists, biochemists, molecular biologists, geneticists, microbiologists, plant physiologists, agriculturalists. A large number of them had to go through a difficult period to raise the necessary funds to attend. In addition, a parallel meeting of "policymakers" from Southeast Asia, Africa and South America was held under the auspices of Crosscurrents International Institute, Dayton, OR, USA and the United Nations University, Tokyo, Japan. These participants attended some of the scientific sessions to benefit from the vision of a number of scientists at the symposium.
