تمكن تقنية جديدة، عبر استخدام الهاتف الذكي، التخلص من استخدام جهاز كبير للأشعة ومن احتمال التعرض لأخطار الإشعاع

 تسمح عدة تقنيات مثل الأشعة والموجات فوق الصوتية والتصوير المقطعي الكومبيوتري والتصوير بالرنين المغناطيسي برؤية ما تحت السطح، ولكن تقنية جديدة تعتمد على الضوء طوُرت في إسرائيل قد تخطو بالطب خطوة أخرى إلى الأمام.

فبدل استخدام جهاز كبير للأشعة واحتمال التعرض لأخطار الإشعاع، أصبح في إمكاننا الآن رؤية ما تحت سطح الجسم والذي يكاد يكون غير شفاف للضوء عبر استخدام الهاتف الذكي.

هذه التقنية الجديدة التي طورت في مختبرات الجامعة العبرية بأورشليم تمكن المختصين من رؤية ما تحت سطح الجسم من خلال تحليل تناثر الضوء.

وقد يحدث هذا البحث الأولي ثورة علمية عبر تحسين جودة الصور المجهرية، وتشخيص الأمراض دونما حاجة إلى جراحة، ذلك أنّ الجلد البشري يعتبر عديم الشفافية للضوء تقريبا.

وحين يصل الضوء إلى سطح غير منفذ للضوء مثل الزجاج المثلج، يتناثر ويضطرب، ليجعلنا عاجزين عن الاطلاع على ما تحت السطح. وكان الباحثون على مر التاريخ يعتقدون بأن تناثر الضوء عشوائي، بمعنى أننا لو عجزنا عن رؤية ما تحت السطح، لا نستطيع استخراج أي معلومة منه.

ولكن البحث الجاري في الجامعة العبرية يروي قصة مختلفة، مفادها أن التناثر ليس عشوائيا، بل يستطيع موافاتنا بكثير من المعلومات لو أننا حللناها بطريقة صحيحة. ويقول د. “أوري كاتس” الذي يشرف على البحث متحدثا إلى مجلة NoCamels: لقد سحرنا بفكرة استخراج المعلومات من شيء يبدو وكأنه خالٍ تماما من المعلومات.

وقد استخدم د. كاتس وفريقه البحثي مؤخرا كاميرا هاتف ذكي لالتقاط صورة لجسم مخفي تحت زجاج مثلج لإحدى النوافذ. ويروي قائلا: “ما نراه في الصورة التي التقطناها مجرد هالة ضبابية للضوء المنبعث من الجسم، ولكن عبر التحليل المتعمق للصلات المتبادلة بين أجزاء الصورة، تمكنّا من إعادة بناء شكل الجسم”، بمعنى أن الضوء في الصورة يكشف عن مميزات الجسم أكثر من الكاميرا أو ما لمحته العين أول الأمر.

  4. I am really impressed with your writing skills and also with the layout on your blog.
    Is this a paid theme or did you customize it yourself?

    Either way keep up the excellent quality writing, it is rare to see a great blog
    like this one today.

  5. about my name. Roonil Wazlib was written inside Ron’s Potions textbook because his Spellcheck Quill started malfunctioning, so he ended up misspelling his own name, the poor thing. Later, Snape asked for all of Harry’s textbooks after he attacked Malfoy in the bathroom (in the 6th book), and Harry couldn’t hand over his own (because it has the Half-Blood Prince’s notes all over it) and remedied by grabbing Ron’s instead.:)

  15. Thanks for the sensible critique. Me & my neighbor were just preparing to do some research about this. We got a grab a book from our area library but I think I learned more clear from this post. I’m very glad to see such fantastic info being shared freely out there.

  16. DanTheHockeyMan^This is by far the most stunning shirt I have ever seen. This here shirt was the 4th shirt I got from The Mountain (my other ones are the Peace Pipes shirt&#44 their Mountain Majesty eagle shirt&#44 and the Eagle Talon Flag shirt)&#44 and no other t-shirt company can even come close to these designs. Their animal shirts are unlike any others&#44 and this Bark at the Moon wolf shirt is no exception. The biggest of the 4 wolves (the 4th one is way out in the background on a different part of the mountain&#44 so that makes this shirt have one more wolf than Three Wolf Moon)&#44 shows the most impressive amount of detail. You can see this wolf’s breath from its howling as if it’s a cool night outside. That right away sold me on this shirt. The shining light coming off the moon&#44 the stars&#44 and the comet&#44 are pretty nice too. The details of the other wolves by the mountain are equally as impressive&#44 as you can really see their expressions on their faces and all their other details. The extra 4th wolf all the way in the background just adds to the epicness of this shirt. As I start wearing this shirt more&#44 hopefully I will get more attention as the power of wolves are just known to do that. Upon my first wearing of this shirt&#44 I noticed it is really soft and comfortable just like all my other shirts from The Mountain. If you want a cool shirt to add to your collection&#44 look no further than this Bark at the Moon wolf shirt.~5|Richard Medwid^Put it this way. I was hiking in Glacier National Park and was waylaid by a Grizzly on a nice&#44 serene daytime hike. Usually a single wolf like myself wouldn’t stand a chance against a Grizzly on his way to dinner. Anyhow&#44 as chance would have it&#44 I happened to wearing my Bark at The Moon T-Shirt that fateful day. The four wolves on my shirt magically appeared and formed a protective circle around me to keep the predator at bay. As the bear probed the wolf defenses&#44 my pack worked in concert to form a formidable defense incapable of being breached. Eventually the bear retreated back towards the cave in which he came&#44 suddenly realizing that working the river in hopes of salmon might yield better returns. I highly recommend this shirt. I wouldn’t be here without it.~5|Jacee^This shirt is a heavy cotton T-shirt&#44 a vibrant print that lasts for a long time and has a generous length for those who are tall. You will not be disappointed! I have ordered from ‘The Mountain’ many&#44 many times and I have not ever been disappointed! I bought two shirts at Christmas this one and one similar to it from a local store. The one from the local store has already fallen apart at the inside armpit seam 🙁 And it has shrunk to short and the picture has faded….a total waist of time and money 🙁 ‘THE MOUNTAIN’ is the BEST for quality and price! Their shirts have not fallen apart and we have had them for years now! I am very pleased and would recommend to anyone and everyone who wants a nice quality shirt that will last a life time! Ok&#44 almost a life time :)~5|Avataress59^great gift~5|A. Cheffy^I bought this for my daughter as a comfy night-shirt in the extra-large. Beautiful graphics&#44 all cotton and not too thick or too thin. Definitely wash this before wearing though because it had that slightly stiff feel to it out of the package.~5|Pat^I HAVE BEEN GETTING MOUNTAIN TEES FOR OVER 20 YEARS&#44 AND I CAN TELL YOU THAT THEIR TEES ARE TOP NOTCH!! IT IS COTTON AND GOOD QUALITY!!! THE BEST PART IS THE ILLUSTRATIONS!!! THEY ARE ALWAYS BEAUTIFUL!! THE TEES LAST A LONG TIME&#44 IF YOU WASH THEM IN COLD WATER AND TURN THEM INSIDE OUT. I DO THAT SO THE PICTURE STAYS FOR A LONG TIME. I HAVE TEES THAT I HAVE HAD FOR MORE THAN 10 YEARS THAT I STILL WEAR!!!! GREAT PRODUCT!!!~5|Galen^I love this shirt. I wear it to Wolf-PAC meetings. It’s my favorite T when I’m bringing a mule deer down with my teeth clenched on its jugular vein or when I’m harrowing lost travelers like Liam Neeson in a remote&#44 snowy wilderness. It really fits just about any situation. Car break-down? You can definitely eat those stranded motorists with this on. Human caught in a bear trap? Blood tastes so irony!~5|Fito^I love these Mountain T-shirts&#44 I’m a very “nature” kind of guy&#44 and every corner of this planet has something that speaks to me in its very deeply beautiful language. This time a wolf&#44 which express some sadness and worry&#44 and below a wolf in alert while resting on the floor. Very nice design. And Its quality exceeded my expectations. Check the other t-shirts&#44 this brand has several amazing designs. Overall very satisfied with my purchase!~5|Assmann^I ordered this shirt as a joke to parody people who seriously wear “3 wolves howling at the moon” t-shirts. I expected to wear it once to get a laugh from my friends but it is surprisingly comfortable and now it is a guilty pleasure of mine wearing it around the house. If you like “3 wolves howling at the moon shirts” I would definately pick it up. I still doubt I will ever wear it outside though unless I forget to do laundry.~5|Shannon^I’ve ordered many medium shirts online here for my teenage son&#44 but this one is a large even though the shirt says medium. The shirt is also really long for a t-shirt. Order one size smaller as this one is large. The picture on the shirt looks great.~4|

  17. May I simply just say what a comfort to find somebody that really understands what they are discussing on the net.
    You definitely know how to bring a problem to light and make
    it important. More and more people have to check this out and understand this side of the story.
    I was surprised that you are not more popular given that you certainly
    have the gift.

  18. Please let me know if you’re looking for a article author for your site.
    You have some really great articles and I believe I would be a good asset.

    If you ever want to take some of the load off, I’d absolutely love to write some
    content for your blog in exchange for a link back to mine.
    Please blast me an e-mail if interested. Thanks!

  19. Hey! I know this is kinda off topic but I was
    wondering which blog platform are you using for this site?
    I’m getting sick and tired of WordPress because
    I’ve had issues with hackers and I’m looking at alternatives for
    another platform. I would be great if you could point me in the direction of a good platform.

  20. Having read this I believed it was extremely enlightening.
    I appreciate you spending some time and effort
    to put this short article together. I once again find myself personally spending a significant amount of time
    both reading and posting comments. But so what, it was still worth it!

  21. Thank you for the great info! I would never have gotten this by myself!

  22. もう遅いかな・・。ウチの娘(現27才)の昔話かとビックリしました。我が家の場合ですが参考になれば。。年長さんから小学校一年・・すぐに手が出てキレる問題児でした。原因は私です。そのころ長患いに加え家庭内がぐちゃぐちゃで、私自体が最悪の時期でした。子どもにその姿を見せないように気をつけ、しつけもしてきたつもりでしたが、子どもは敏感に母親の不安定を感じ取っていたようです。娘の状況を知ったのは、近所の仲良しのお母様からと、一年の担任の先生から。私はまったく気づいていませんでした。担任の先生に家庭の状況も話し、全面的に助けていただきました。その時の先生の言葉は今でも私の宝物です。○○ちゃんはすぐ手が出て乱暴者と言われている。それは欠点と言われるかもしれない。でも欠点と長所はその子の性格の裏と表なんです。表が出るようにすれば良いのです。性格を否定してはいけません。絶対に怒らないでください。(裏)すぐ手が出る→(表)感情を表現できる(裏)ガキ大将のふるまい→(表)リーダーシップがある(裏)わがままで自己中→(表)主義主張がはっきりしている。などなど。性格が裏に出る理由は必ずあります。今回は家庭の不安定による寂しさ。毎日抱きしめてあげてください。その後先生は密に連絡をくださり、一緒に「性格を表にする」ご苦労をしてくださいました。それほど時間をかけずに落ち着きました。その後、娘本人曰く。親の前ではおとなしくいい子にしていて、外でキレていた。毎日イライラしてどうしていいかわからなかった。乱暴してると先生には止められたたけど、怒られなかった。「○○ちゃんはこんな良いところがあるのに、今日はどうしたの?」と聞いてくれた。拍子抜けした。嬉しかった。今娘は図書館の児童室に勤務しています。読み聞かせは年齢制限なし、希望されれば高校生にもするそうです。読み聞かせは「本を読んであげる」でなく、気持ちのキャッチボールだと言ってます。自分の経験からか「問題児」と言われてる子がかわいくってしょうがないらしい。「いじめっこしてたが経験が活かせたわ。人生無駄がない。」と自信満々です。

  24. Något som jag undrar över är ju varför alla LCHF ätare är så rädda för frukt, då det inte påverkar insulinet nämnvärt, utan omvandlar fruktsockret till fett i levern först. Fett är de ju inte rädda för vad jag vet. Kroppen gör väl ingen skillnad på varifrån fettenergin kommer från. Detta gäller människor med hyfsad fysisk aktiviet, som inte har konstant fulla glyk.lager i muskler m.m.Helen

  25. Cathy^Reasonable quality&#44 t-shirt type fabric. It’s a bit pricy but I haven’t been able to find Pusheen T-shirts locally. My daughter really likes it and says it’s comfortable. She is very slim&#44 and the t-shirt fits her just a little loosely.~4|Scott M.^DO NOT BUY!!! Product is not 100% Preshrunk Cotton as advertised. My daughter received a thin polyester/rayon shirt.~3|Erica^Poor quality all around. Pixel ates image and thin&#44 odd fabric.~3|finsrin^Love this cat/mermaid t-shirt&#44 i wore it to celebrate my grandsons 2nd birthday @ seaworld. I got asked multiple times if i had purchased it in the park. Very cute and comfy.~5|A. Hendricks^love the tee-shirt&#44 but don’t think this is a sanctioned Pusheen design. The copy of the image is blurry. We kept the shirt&#44 but will know better next time.~3|Nicole Foster^Great product&#44 my daughter loves it~5|Amazon Customer^Excellent quality and fit. Print appears to be substantial so I don’t have to worry about it coming off in the wash.~5|frequent shopper^Great quality! Not like some of the cheap imposters&#44 this t-shirt and graphic is soooo cute! My daughter LOVES it.~5|primeshopper^My 13 yr. old neice loved it. A must for ny Pusheen lover out there – colors were good! Soft tee.~5|Amazon Customer^Granddaughter will love it.~4|
