قایقی خواهم ساخت

emjm — Sat, 14 Nov 2009 17:07:01 GMT

قایقی خواهم ساخت،
خواهم انداخت به آب.
دور خواهم شد از این خاک غریب
که در آن هیچ‌کسی نیست که در بیشه عشق
قهرمانان را بیدار کند.

قایق از تور تهی
و دل از آرزوی مروارید،
هم‌چنان خواهم راند.
نه به آبی‌ها دل خواهم بست
نه به دریا-پریانی که سر از خاک به در می‌آرند
و در آن تابش تنهایی ماهی‌گیران
می‌فشانند فسون از سر گیسوهاشان.

هم‌چنان خواهم راند.
هم‌چنان خواهم خواند:
“دور باید شد، دور.”
مرد آن شهر اساطیر نداشت.
زن آن شهر به سرشاری یک خوشه انگور نبود.

هیچ آیینه تالاری، سرخوشی‌ها را تکرار نکرد.
چاله آبی حتی، مشعلی را ننمود.
دور باید شد، دور.
شب سرودش را خواند،
نوبت پنجره‌هاست.”

هم‌چنان خواهم خواند.
هم‌چنان خواهم راند.

پشت دریاها شهری است
که در آن پنجره‌ها رو به تجلی باز است.
بام‌ها جای کبوترهایی است که به فواره هوش بشری می‌نگرند.
دست هر کودک ده ساله شهر، خانه معرفتی است.
مردم شهر به یک چینه چنان می‌نگرند
که به یک شعله، به یک خواب لطیف.
خاک، موسیقی احساس تو را می‌شنود
و صدای پر مرغان اساطیر می‌آید در باد.

پشت دریاها شهری است
که در آن وسعت خورشید به اندازه چشمان سحرخیزان است.
شاعران وارث آب و خرد و روشنی‌اند.

پشت دریاها شهری است!
قایقی باید ساخت.

کتاب آنالیز عمر خستگی سازه های جوشی Fatigue Life Analyses of Welded Structures

Fatigue Life Analyses of Welded Structures (FLAWS)

Avoiding or controlling fatigue damage is a major issue in the design and inspection of welded structures subjected to dynamic loading. Life predictions are usually used for safe life analysis, i.e. for verifying that it is very unlikely that fatigue damage will occur during the target service life of a structure. Damage tolerance analysis is used for predicting the behavior of a fatigue crack and for planning of in-service scheduled inspections.
It should be a high probability that any cracks appearing are detected and repaired before they become critical. In both safe life analysis and the damage tolerance analysis there may be large uncertainties involved that have to be treated in a logical and consistent manner by stochastic modeling.
This book focuses on fatigue life predictions and damage tolerance analysis of welded joints and is divided into three parts. The first part outlines the common practice used for safe life and damage tolerance analysis with reference to rules and regulations. The second part emphasises stochastic modeling and decision-making under uncertainty, while the final part is devoted to recent advances within fatigue research on welded joints. Industrial examples that are included are mainly dealing with offshore steel structures. Spreadsheets which accompany the book give the reader the possibility for hands-on experience of fatigue life predictions, crack growth analysis and inspection planning. As such, these different areas will be of use to engineers and researchers.

Fundamentals of Corrosion: Mechanisms, Causes, and Preventative Methods

Philip A. Schweitzer P.E.
CRC 2009 | ISBN-10: 1420067702 | 416 Pages | PDF | 2,9 MB

ساليانه بيليون‌ها دلار براي جايگزيني و تعويض سازه‌ها ، ماشين آلات ، اجزا و قطعات خورده شده خرج مي‌شود.همچنين خرابي زود‌هنگام پل‌ها يا سازه‌ها به علت خوردگي مي‌تواند صدمات انساني ، جان باختگي و خسارت‌هاي جنبي ديگر را نتيجه دهد.

اين كتاب “اصول خوردگي – مكانيزم‌ها ، اسباب و اندازه‌گيري‌هاي پيشگيرانه” توسط يكي از بانيان دانش خوردگي نوشته شده است و دلائل خوردگي و ابزارهايي براي محدود كردن و يا جلوگيري كردن از آن را به طور جامع شرح مي‌دهد.

مهندسين ، طراحان ، معماران و همه آنهايي كه با انتخاب مصالح ساخت و ساز درگير هستند از يك مرجع كه چنين امكاني را از طريق تشريح اصولي عوامل ، پيشگيري و كنترل خوردگي را فراهم مي‌كند، ملحوظ خواهند شد.

اين مرجع موارد زير را مورد كاوش قرار مي‌دهد:
-اشكال و مكانيزم‌هاي خوردگي
-روش‌هاي حمله به مواد نرم و شكل‌پذير
-دلائل خرابي پوشش‌هاي ، روكش‌ها و رنگ‌هاي محافظتي
-تكامل آليا‍‌ژهاي جديد با خاصيت مقاومت در برابر خوردگي

يكي از بزرگترين مشكلات و دلائل خوردگي كه مهندسان و طراحان در ساخت با آن مواجه هستند ، قرارگيري در معرض اتمسفر مي‌باشد. برآورد تكميلي شده است كه هزينه محافظت در برابر خوردگي محيطي ، تقريبا با نيمي از هزينه‌هاي كلي تمامي روش‌هاي محافظت برابري مي‌كند. اين كتاب تاكيد و‌يژه‌اي بر روي قرارگيري در معرض اتمسفر دارد و اطلاعات حياتي مربوط به طراحي سازه‌ها ، خودروها ، لوله‌كشي خانگي ، دستگاه‌هاي توليد و ساير موارد همانند تاثيرات مواد شيميايي يخ‌زدا بر روي بزرگ‌راه‌ها و پل‌ها را ارائه مي‌دهد

Billions of dollars are spent annually for the replacement of corroded structures, machinery, and components. Premature failure of bridges or structures due to corrosion can also result in human injury, loss of life, and collateral damage. Written by an authority in corrosion science, Fundamentals of Corrosion: Mechanisms, Causes, and Preventative Measures comprehensively describes the causes of corrosion—and the means to limit or prevent it. Engineers, designers, architects, and all those involved with the selection of construction materials will relish a reference that provides such a thorough yet basic illustration of the causes, prevention, and control of corrosion.This reference explores:
Mechanisms and forms of corrosion Methods of attack on plastic materialsCauses of failure in protective coatings, linings, and paints
Development of new alloys with corrosion-resistant properties Exposure to the atmosphere is one of the largest problems and biggest causes of corrosion that engineers and designers face in construction. It has been further estimated that the cost of protection against atmospheric corrosion accounts for approximately half the total cost of all corrosion protection methods. This book places special emphasis on atmospheric exposure and presents vital information regarding the design of structures, automobiles, household plumbing, manufacturing equipment, and other entities, as well as the effects of de-icing chemicals on highways and bridges.

Handbook of Sealant Technology

Publisher: CRC | Pages: 532 | 2009-08-26 | ISBN 0849391628 | PDF | 8 MB

Sealing is an age-old problem that dates back to our earliest attempts to create a more comfortable living environment. Prehistoric people used natural sealants such as earth, loam, grass, and reeds to protect the interior of their homes against the weather. Today’s applications extend to a myriad of uses. The Handbook of Sealant Technology provides an in-depth examination of sealants, reviewing their historical developments and fundamentals, adhesion theories and properties, and today’s wide range of applications.
