آرواره مکانیکی به تحقیق درباره مواد دندانسازی کمک می کند




این روبات توسط آقای رابه دانشجوی دانشگاه بریستول ساخته شده است
یک گروه محقق از دانشگاه بریستول انگلستان روباتی ساخته است که درک بهتر سائیدگی و تخریب دندان را امکانپذیر می کند.
این "روبات جونده"، جایگزین مناسبی است برای تحقیق در باره انواع جدید تاج دندان و موادی که برای ترمیم و بازسازی دندان استفاده می شود.
مطالعه عملکرد و دوام این مواد در انسان نه تنها هزینه بردار است بلکه همچنین به زمان زیادی نیاز دارد.
اما این آرواره مکانیکی جدید خیلی عالی ادای آرواره انسان و عمل جوئیدن را در می آورد.
دکتر کاظم عالمزادف، از دانشگاه بریستول بعد از این که عملکرد شبیه ساز پرواز با هواپیما را مشاهده کرد و متوجه شد که در آن از حرکت های مشابه آرواره استفاده می شود، به فکر طراحی آرواره مکانیکی افتاد.
ساخت و بهتر کردن طرح پیشنهادی او توسط دانیال رابه، دانشجوی مقطع دکترا در رشته مهندسی مکانیک این دانشگاه انجام گرفته است.
آقای رابه گفت: "با بازسازی عمل جویدن و حرکت های آرواره به طور طبیعی در انسان، روبات جونده می تواند به تولید مواد جدیدی کمک کند که برای ترمیم دندان انسان استفاده می شود."
بریتانیا هر سال دو و نیم میلیارد پوند برای موادی که برای ترمیم یا استحکام بخشیدن به دندان استفاده می شود، هزینه می کند.
آرواره مکانیکی در حال حاضر در نمایشگاه تابستانی علوم "رویال سوسایتی" در لندن به نمایش گذاشته شده است. رویال سوسایتی، آکادمی علوم ملی بریتانیا و نهادی مستقل است.

تجارت سکس- برگرفته شده از سایت فارسی بی بی سی


مقام های امنیتی از سراسر آسیا که نشستی را در استرالیا برگزار کرده بودند، تصمیم گرفته اند عملیات مشترک بی سابقه ای را به اجرا گذارند که هدف از انجام آن جلوگیری از قاچاق افراد به منظور تجارت سکس است.
در این نشست گفته شد که تجارت سکس بسیار سازماندهی شده تر از آن است که در ابتدا تصور می شده است.
مقام های امنیتی در آسیا معتقدند که غالب قربانیان این تجارت که به استرالیا قاچاق می شوند زنان جوان اهل جنوب شرقی آسیا هستند.
آنها اکثرا فریب خورده اند یا با خشونت وادار شده اند به استرالیا سفر کنند و وارد تجارت سکس شوند.
عملا بسیاری از زنانی که برای تجارت سکس قاچاق شده اند، گروگان این صنعت هستند چون بدهکاری مالی آنها به تبهکاران هنگفت است.
مقام های امنیتی که در نشست استرالیا شرکت داشتند به توافق رسیدند که باید تلاش های خود را در مبارزه با این تجارت شدت بخشند.
شرکت کنندگان همچنین گفتند که تحقیقات جدید مشترک مرزی صورت خواهد گرفت.
رمزی جبور، فرمانده پلیس استرالیا، معتقد است که افزایش همکاری های منطقه ای در بهبود این وضعیت موثر است.
او گفت: "اگر ما به تنهایی کار کنیم، مالزی به تنهایی فعالیت کند، تایلندی های به صورت انفرادی با تجارت سکس مبارزه کنند، ممکن است کسی متوجه نشود که فقط یکی دو نفر هستند که این سندیکاهای جنایتکار را هدایت می کنند."
آمار قابل اعتمادی در ارتباط با شمار افرادی که هر ساله برای تجارت سکس به استرالیا قاچاق می شوند وجود ندارد، اما تخمین های متعدد حاکی از آن بوده که رقم آن به هزار نفر می رسد.
محاکمه های موفق نادر بوده است اما مقام های استرالیا واحد ویژه ای را راه اندازی کرده اند تا در باره ادعاهایی تحقیق کند که در ارتباط با برده داری مطرح شده است.
سازمان های خیریه گفته اند که قربانیان قاچاق وادار می شوند در شرایط بسیار بدی به عنوان مستخدم خانگی، کارگر مزارع و کارگر ساختمانی به کار گرفته می شوند.

عشق و دوستی


Love starts with a smile, grows with a kiss, and ends with a tear. Don't cry over anyone who won't cry over you.



Good friends are hard to find, harder to leave, and impossible to forget. You can only go as far as you push. Actions speak louder than words



The hardest thing to do is watch the one you love, love somebody else. Don't let the past hold you back; you're missing the good stuff. Life's short. If you don't look around once in a while, you might miss it.


A best friend is like a four leaf clover: hard to find and lucky to haveIf you think that the world means nothing, think again.
You might mean the world to someone else.When it hurts to look back, and you're scared to look ahead, you can look beside you andyour best friend will be there



True friendship never ends. Friends are forever. Good friends are like stars....You don't always see them, but you know they are always there.


Don't frown. You never know who is falling in love with your smile. What do you do when the only person who can make you stop crying is the person who made you cry?



NOBODY IS PERFECT UNTIL YOU FALL IN LOVE WITH THEM

محققان: مصرف چربی حیوانی با سرطان لوزالمعده ارتباط دارد

محققان آمریکایی می گویند مصرف زیاد گوشت قرمز و لبنیات احتمال ابتلا به سرطان لوزالمعده را افزایش می دهد.
محققان موسسه ملی سرطان در مریلند پس از مطالعه عادت های غذایی پانصدهزار نفر در طول شش سال به این نتیجه رسیدند با افزایش مصرف چربی های حیوانی، احتمال ابتلا به سرطان نیز افزایش می یابد.
نتیجه این تحقیق در مجله موسسه ملی سرطان منتشر شده است.
کارشناسان می گویند کاهش مصرف چربی های حیوانی به پیشگیری از بروز سرطان موثر است.
مصرف سیگار بزرگ ترین عامل ابتلا به سرطان لوزالمعده است. این بیماری از پیش آگهی خوبی برخوردار نیست و معمولا فاصله زمانی میان تشخیص آن تا مرگ حدود شش ماه است.
پیش از این محققان درباره نقش چربی های حیوانی در بروز سرطان لوزالمعده نظرات متناقضی را ارائه کرده بودند.
به همین علت محققان موسسه ملی سرطان در بتزدای مریلند که در حومه واشنگتن قرار دارد، تصمیم گرفتند با تحقیق بر روی نیم میلیون نفر، بیشترین دقت آماری را در تحقیقات خود داشته باشند.
از این میان نزدیک به یک هزار و چهارصد تن از افراد مورد بررسی به سرطان لوزالمعده مبتلا شدند.
بر اساس نتیجه این تحقیق، احتمال ابتلا به سرطان لوزالمعده در افرادی که رژیم غذایی پرچربی دارند، سی و شش درصد بیشتر از دیگران است.
در این حال، احتمال ابتلای مردان به این بیماری بیشتر از زنان است و این رقم برای آنها 53 درصد و زنان 23 درصد است.
پزشکان می گویند توقف مصرف دخانیات، افزایش مصرف میوه و سبزیجات و محدود کردن مصرف گوشت قرمز، غذاهای چرب و الکل بهترین راه برای پیشگیری از ابتلا به سرطان لوزالمعده است.

love











You will find as you look back upon your life,
that the moments when you have really lived,
are the moments when you have done things in the spirit of love.


Immature love says,
"I love you because I need you.
" Mature love says,
"I need you because I love you."



The quality of love and the duration of a relationship are in direct
proportion to the depth of the commitment by both people
to making the relationship successful.
Commit yourself wholeheartedly and unconditionally to
the most important people in your life.



How on earth are you ever going to explain in terms of chemistry
and physics so important a biological phenomenon as first love?



Love is like a friendship caught on fire.
In the beginning a flame,
very pretty, often hot and fierce,
but still only light and flickering.
As love grows older, our hearts mature and our love
becomes as coals, deep-burning and unquenchable.



It's easy to fall in love.
The hard part is finding someone to catch you.



Love doesn't make the world go round.
Love is what makes the ride worthwhile.



For you see, each day I love you more.
Today more than yesterday and less than tomorrow.



Of all forms of caution,
caution in love is perhaps the most fatal to true happiness.



When the power of love,
overcomes the love of power,
the world will know peace.



Two things only a man cannot hide:
that he is drunk and that he is in love
