    تاریخچه

 

    پیاز یکی از سبزیهای مهم و مشهور دنیا است . این سبزی در بیشتر نقاط دنیا کشت می شود . پیاز گیاه بومی جنوب غربی آسیا و احتمالا مربوط به ناحیه ای بین فلسطین و هندوستان و یا منطقه شرق مدیترانه می باشد . بعضی ایران را موطن اصلی پیاز می دانند ،  از زمانهای بسیار قدیم پیاز کشت می شده است و مردم به خصوصیات این سبزی پی برده اند .

 

    تاریخچه استفاده از آن به عنوان غذا به زمانی می رسد که تاریخ نوشته شده است . کشور مصر به خاطر کاشت نوعی پیاز مشهور بوده است . کشت آن در این کشور با 5000 سال قبل از میلاد مسیح می رسد و در اهرام مصر پیاز کشف گردیده است . در نوشته رومیان و یونانیان مطالبی در مورد پیاز به چشم می خورد ، و نیز در کتاب مقدس مسیحیان از  آن نام برده شده است . در قرآن کریم نیز به نام (بصل)‌ از آن صحبت به میان آمده .

 

    پیاز یکی از موادی بود که قوم بنی اسرائیل در موقع مهاجرت از مصر در بیابانهای عربستان خواهان آن بودند .

 

 

 

 

 

 

 

 

 

 

 

 

 

    مشخصات گیاه شناسی

 

    نام علمی پیاز Allium cepa  است و از خانواده سوسنیها   Liliacea  است . پیاز با وجود اینکه دو یا چند ساله است در سبزی کاری به طور محصول یک ساله کاشته می شود . جنس Allium cepa  دارای گونه های زیادی است ،‌ که اغلب تولید غده پیاز کرده ،‌ ولی گونه های وحشی در این جنس یافت می شود ،‌ که به جای تولید بذر ،‌ تولید پیازچه های کوچک در خوشه گل می کند ،‌ که برای تکثیر از آن استفاده می شود .

 

 

 

    گل 

 

گل پیاز دارای سه پرچم و یک تخمدان 6 برچه ای می باشد  . ساقه گل دهنده همانند توپ به نظر می رسد .

 

 

 

    ساقه

            پیاز دارای ساقه پهن  نازک ،‌ مدور ،‌  سفید رنگ

کاربرد های لیزر

 

مقدمه

 

امروزه لیزر کاربردهای بیشماری دارد که همه زمینه های مختلف علمی و فنی فیزیک-شیمی-زیست شناسی - الکترونیک و پزشکی را شامل می‌شود. همه این کاربردها نتیجه مستقیم همان ویژگی‌های خاص نور لیزر است.

 

کاربرد لیزر در فیزیک و شیمی

 

اختراع لیزر و تکامل آن وابسته به معلومات پایه‌ای است که در درجه اول از رشته فیزیک و بعد از شیمی گرفته شده‌اند. بنابراین طبیعی است که استفاده از لیزر در فیزیک و شیمی از اولین کاربردهای لیزر باشند.

 

رشته دیگری که در آن لیزر نه تنها امکانات موجود را افزایش داده بلکه مفاهیم کاملا جدیدی را عرضه کرده است طیف نمایی است. اکنون با بعضی از لیزرها می‌توان پهنای خط نوسانی را تا چند ده کیلو هرتز باریک کرد (هم در ناحیه مرئی و هم در ناحیه فروسرخ) و با این کار اندازه گیری‌های مربوط به طیف نمایی با توان تفکیک چند مرتبه بزرگی ( 3 تا 6) بالاتر از روش های معمولی طیف نمایی امکان پذیر  می‌شوند. لیزر همچنین باعث ابداع رشته جدید طیف نمایی غیر خطی شد که در آن تفکیک طیف نمایی خیلی بالاتر از حدی است که معمولا با اثرهای پهن شدگی دوپلر اعمال می‌شود. این عمل منجر به بررسیهای دقیقتری از خصوصیات ماده شده است.

 

در زمینه شیمی از لیزر هم برای تشخیص و هم برای ایجاد تغییرات شیمیایی برگشت ناپذیر استفاده شده است. ( فوتو شیمی لیزری) به ویژه در فون تشخیص باید از روش‌های  (پراکندگی تشدیدی رامان) و (پراکندگی پاد استوکس همدوس رامان) (CARS) نام ببریم. به وسیله این روشها می توان اطلاعات قابل ملاحظه‌ای درباره خصوصیات مولکول‌های چند اتمی به دست آورد (یعنی فرکانس ارتعاشی فعال رامن - ثابتهای چرخشی و ناهماهنگ بودن فرکانس). روش CARS همچنین برای اندازه گیری غلظت و دمای یک نمونه مولکولی در یک ناحیه محدود از فضا به کار می‌رود. از این توانایی برای بررسی جزئیات فرایند احتراق شعله و پلاسما ( تخلیه الکتریکی) بهره برداری شده است.

 

شاید جالبتری کاربرد شیمیایی ( دست کم بالقوه ) لیزر در زیمنه فوتو شیمی باشد. اما باید در نظر داشته باشیم به خاطر بهای زیاد فوتونهای لیزری بهره برداری تجاری از فوتو شیمی لیزری تنها هنگامی مواجه است که ارزش محصول نهایی خیلی زیاد باشد. یکی از این موارد جداسازی ایزوتوپها است.

 

کاربرد در زیست شناسی

 

از لیزر به طور روزافزونی در زیست شناسی و پزشکی استفاده می‌شود. اینجا هم لیزر می تواند ابزار تشخیص و یا وسیله برگشت ناپذیر مولکولهای زنده یک سلول و یا یک بافت باشد. (زیست شناسی نوری و جراحی لیزری)

 

در زیست شناسی مهمترین کاربرد لیزر به عنوان یک وسیله تشخیصی است. ما در اینجا تکنیک های لیزری زیر را ذکر می کنیم :

 

الف) فلوئورسان القایی به وسیله تپهای فوق العاده کوتاه لیزر در DNA در ترکیب رنگی پیچیده DNA و در مواد رنگی موثر در فتوسنتز

 

ب) پراکندگی تشدیدی رامان به عنوان روشی برای مطالعه ملکولهای زنده مانند هموگلوبین و یا رودوپسین ( عامل اصلی در سازوکار بینایی)

 

ج) طیف نمایی همبستگی فوتونی برای بدست آوردن اطلاعاتی در مورد ساختار و درجه انبوهش انواع ملکولهای زنده

مقدمه:

بی شک معطوف شدن نگاههای والدین و جامعه ی آموزش کشور به برآورده ساختن نیازهای علمی دانش آموزان سبب شده است تا نیازهای روحی آن دسته از افراد در بین مشکلات گوناگون کم رنگ شود اگر خصوصیاتی نظیر گذشت، همدلی، شوخ طبعی، کمک به دیگران درک ضعف خود و دیگران ، عدالت خواهی، رازداری، کنترل خشم و احساسی بودن را از جمله ویژگیهای هوش هیجانی یا هوش اجتماعی بدانیم ضرورت دارد که سازمان آموزش و پرورش کشور دانش آموزان مستعد و مدیران آینده کشور را تربیت کند. بررسی های انجام شده در تعیین هوش هیجانی نشان داده است که هوش هیجانی در دانش آموزان خودنمایی می کند. و به همین علت است که در طول سالیان دراز مدارس جهت توجه به این نیازهای درونی اقداماتی مانند المپیادهای ورزشی، طرح پژوهش های دانش آموزی، ابداعات و خلاقیت در زمینه های علوم انسانی در برنامه های مدارس گنجانده شده است. تحقیقاتی در زمینه توضیح رابطه هوش هیجانی و پیشرفت تحصیلی در دنیا و در ایران به عمل آمده است و اغلب معنادار بودن رابطه را نشان داده است. هوش هیجانی خود به تنهایی تولیدکننده ی موفقیت نیست اما واقعیت این است که اسنادهای مثبت در درازمدت می تواند عامل پیش بینی کننده ی خوبی برای موفقیت باشد (سیارویی و همکاران، 1384)

The Easiest and Fastest Way to Learn Italian
Whether you want to travel, communicate with friends or colleagues, reconnect with family, or just understand more of what’s going on in the world around you, learning Italian will expand your horizons and immeasurably enrich your life.

The best part is that it doesn’t have to be difficult or take years to master. Thirty minutes a day is all it takes, and we get you speaking right from the first day. Pimsleur courses use a scientifically-proven method that puts you in control of your learning. If you’ve tried other language learning methods but found they simply didn’t stick, then you owe it to yourself to give Pimsleur a try.

Why Pimsleur?
- Quick + Easy – Only 30 minutes a day.
- Portable + Flexible – Core lessons can be done anytime, anywhere, and easily fit into your busy life.
- Proven Method – Works when other methods fail.
- Self-Paced – Go fast or go slow – it’s up to you.
- Based in Science – Developed using proven research on memory and learning.
- Cost-effective – Less expensive than classes or immersion, and features all native speakers.
- Genius – Triggers your brain’s natural aptitude to learn.
- Works for everyone – Recommended for ages 13 and above.

What’s Included?
- 30, 30-minute audio lessons
- 60 minutes of reading instruction to provide you with an introduction to reading Italian designed to teach you to sound out words with correct pronunciation and accent
- in total, 16 hours of audio, all featuring native speakers
- a Reading Booklet and a User’s Guide

What You’ll Learn
In the first 10 lessons, you’ll cover the basics: saying hello, asking for or giving information, scheduling a meal or a meeting, asking for or giving basic directions, and much more. You’ll be able to handle minimum courtesy requirements, understand much of what you hear, and be understood at a beginning level, but with near-native pronunciation skills.

In the next 10 lessons, you’ll build on what you’ve learned. Expand your menu, increase your scheduling abilities from general to specific, start to deal with currency and exchanging money, refine your conversations and add over a hundred new vocabulary items. You’ll understand more of what you hear, and be able to participate with speech that is smoother and more confident.

In the final 10 lessons, you’ll be speaking and understanding at an intermediate level. In this phase, more directions are given in the target language, which moves your learning to a whole new plane. Lessons include shopping, visiting friends, going to a restaurant, plans for the evening, car trips, and talking about family. You’ll be able to speak comfortably about things that happened in the past and make plans for the future.

Reading Lessons begin in Lesson 9 to provide you with an introduction to reading Italian. In addition, the combined Reading Lessons are included after Lesson 30. These Reading Lessons, which total about one hour, are designed to teach you to sound out words with correct pronunciation and accent.

The Pimsleur Method
We make no secret of what makes this powerful method work so well. Paul Pimsleur spent his career researching and perfecting the precise elements anyone can use to learn a language quickly and easily. Here are a few of his “secrets”:

The Principle of Anticipation
In the nanosecond between a cue and your response, your brain has to work to come up with the right word. Having to do this boosts retention, and cements the word in your mind.

Core Vocabulary
Words, phrases, and sentences are selected for their usefulness in everyday conversation. We don’t overwhelm you with too much, but steadily increase your ability with every lesson.

Graduated Interval Recall
Reminders of new words and structures come up at the exact interval for maximum retention and storage into your long-term memory.

Organic Learning
You work on multiple aspects of the language simultaneously. We integrate grammar, vocabulary, rhythm, melody, and intonation into every lesson, which allows you to experience the language as a living, expressive form of human culture.

Learning in Context
Research has shown that learning new words in context dramatically accelerates your ability to remember. Every scene in every Pimsleur lesson is set inside a conversation between two people. There are no drills, and no memorization necessary for success.

Active Participation
The Pimsleur Method + active learner participation = success. This method works with every language and every learner who follows it. You gain the power to recall and use what you know, and to add new words easily, exactly as you do in English.

The Italian Language
Italian is the official language of Italy and San Marino, and one of the official languages of Switzerland, Croatia, and Slovenia. Italian is spoken by about 58 million people in Italy, 24,000 in San Marino, 840,000 in Switzerland, another million in other European countries, and approximately 5 million in North and South America. Historically, Italian is a daughter language of Latin. Italian uses the Roman alphabet and the pronunciation of the language follows the spelling very closely.

The Pimsleur Method + active learner participation = success. This method works with every language and every learner who follows it. You gain the power to recall and use what you know, and to add new words easily, exactly as you do in English.

The Italian Language
Italian is the official language of Italy and San Marino, and one of the official languages of Switzerland, Croatia, and Slovenia. Italian is spoken by about 58 million people in Italy, 24,000 in San Marino, 840,000 in Switzerland, another million in other European countries, and approximately 5 million in North and South America. Historically, Italian is a daughter language of Latin. Italian uses the Roman alphabet and the pronunciation of the language follows the spelling very closely.
