थ्री डि प्रिन्टरबाट तयार गरिएको मेरुदण्डलाई बालकको शरीरमा लगाइयो

http://hamroknowledge.blogspot.com/
चीनका डाक्टरहरुले थ्री डि प्रिन्टरबाट प्रिन्ट गरिएको मेरुदण्डलाई सफलतापूवर्क एक १२ वर्षीय बालकको शरीरमा इम्प्लान्ट गरेका छन् । ती बालक हड्डीको क्यान्सरबाट पीडित थिए ।

डाक्टरहरुका अनुसार उनीहरुले यस्तो प्रकारको सर्जरी पहिलो पटक गरेका हुन् । यसका लागि ५ घण्टा लागेको थियो ।

उक्त मेरुदण्ड टाइटानियम पाउडरले बताइएको र बालकको हड्डीलाई बढ्न दिन त्यसमा स साना प्वालहरु बनाइएका छन् ।

एक दिन उक्त बालक फुटबल खेल्दै गर्दा बललाई हेड गर्दा घाँटीमा चोट लागेको थियो । जब उनलाई उपचारका लागि अस्पताल लगियो त्यतिबेला मेरुदण्डमा ट्युमर रहेको पत्ता लागेको थियो ।

पेकिङको अर्थोपेडिक्स डिपार्टमेन्टका डाइरेक्ट लिउ झोङजुनका अनुसार यस नयाँ प्रविधि प्रयोग गर्दा परम्परागत इम्प्लान्ट जस्तै स्क्रीउ र सिमेन्ट प्रयोग गर्न पर्दैन । यो परम्परागत इम्प्लान्ट भन्दा मजबुत हुने पनि उनीहरुको दाबी छ ।

यो प्रविधिले कुनै पनि बिरामीलाई अवश्यक शरीरको कुनै पनि भाग तुरुन्तै निर्माण गर्न मद्दत पुग्ने डाक्टरहरु बताउँछन् ।

अब रायोको सागले गुडाउनेछ कार

कार गुड्न पेट्रोल होइन अब रायोको साग भए पुग्नेछ । वैज्ञानिकहरुले रायोको सागमा यस्तो क्षमता भेट्टाएका छन् जसले सूर्यको प्रकाशलाई वैकल्पिक स्वच्छ उर्जामा परिणत गर्न सक्छ । अमेरिकाको एरिजोना र पुर्ड्यु विश्वविद्यालयका शोधकर्ताहरुले रायोको सागबाट निकालिएको फोटोसिस्टम-२ नामक प्रोटिन कम्प्लेक्स लाई वैकल्पिक उर्जा उत्पादनमा प्रयोग गर्न सकिने विधि पत्ता लगाएका हुन् ।
शोधकर्ताहरुले यो प्रोटिनलाई लेजर प्रकाशको माध्यमबाट उत्प्रेरित गराएपछि त्यसका अणुमा रहेका इलेक्ट्रोनको संरचनामा परिवर्तन भएको पाए ।

त्यो प्रोटिन कम्प्लेक्स काम गर्नका लागि प्रकाश आवश्यक परेकोमा लेजरलाई सूर्यको प्रकाशको रुपमा प्रयोगशालामा प्रयोग गरियो । प्रोटिनले काम गर्न थालेपछि शोधकर्ताहरुले इलेक्ट्रोन प्याराम्याग्नेटिक रिजोनेन्स तथा एक्स रे स्पेक्ट्रोस्कोपीको प्रयोग गरी इलेक्ट्रोनका संरचना कसरी परिवर्तन भए भन्ने कुराको अवलोकन गरे ।
‘हामीले अध्ययन गरेका प्रोटिनहरु अहिलेसम्मकै सबैभन्दा शक्तिशाली प्रणालीको रुपमा रहेका छन् जसले सूर्यको प्रकाश शक्तिलाई रासायनिक शक्तिमा बदल्ने काममा ६० प्रतिशत दक्षता प्रदर्शन गर्छन्’, पुर्ड्यु विश्वविद्यालयकी शोधकर्ता युलिया पुष्कर बताउँछिन् ।
यो प्रणालीको माध्यमबाट कृत्रिम प्रकाश सस्लेसणमार्फत वैकल्पिक उर्जा उत्पादनमा प्रयोग गर्न सकिने सम्भावनाको ठोका उघ्रेको शोधकर्ता बताउँछन् । कृत्रिम प्रकाश संस्लेषणको माध्यमबाट शौर्य उर्जालाई नविकरणीय, वातावरणमैत्री हाइड्रोजनमा आधारिक इन्धनमा परिणत गर्न सकिने र सोही उर्जालाई गाडी गुडाउन लगायतका अन्य विभिन्न काममा समेत प्रयोग गर्न सकिने सम्भावना रहेको शोधकर्ताहरुको भनाइ छ ।

The Method to Write Compelling Headline That People Can't Resist

Headlines are the most crucial and overlooked part of writing an article. It's the first impression you make on any prospective readers. Without a compelling headline that turns a browser into a potential readers, your killer content can go to waste.

Even if you have a large chunk of subscribers. Most people will see your headline along with some other headlines in their feed reader, and it's obvious that they can't read all post in their feed reader, they only pick the one's that have a compelling headline and draw their curiosity to read the full story.

Imagine a newspaper or magazine with no headlines. Imagine a print ad with no headlines. Imagine a long-form sales page with no headlines.

A waste i guess?

People today are hunting for information. With so many blogs to read, so many stuffs to Like on Facebook, so many tweets to favorite or re-tweet, so many videos to watch. But how do you entice readers to consider your content first?

You need to focus on your ability to write compelling headline!
You don't have to be a pro-writer, it just about the way you can create curiosity and study what work best.

If you aren't confident in your ability to write outstanding headlines, you're not alone. Most bloggers and writers find it so challenging to actually craft captivating headlines.
I sometimes deliberate over titles for 30-60 minutes before i finally settle for one that works. And I often go back and change them if their performance are poor. This is what it takes to write a good headline.

If you are stuck and couldn't write a compelling headline for your blog, try these simple tricks that works for me:

  1.  Count The Benefits

Write about 50 ways to do something your audience might find interesting and helpful, and see a great upsurge in your site statistics.

If you are writing a post that shows 20 tips to blog as a pro, why don’t you show in the title that you are providing 20 tips?

    10 tips to blog like a pro
    10 tips to write great content that convert
    15 ways to suck your blog
    9 smart ways to get free quality blog traffic

There aren’t really any rules regarding what numbers work best, but large number like 42 or 50 can catch people’s attention, because it will show readers that you have a lot to say on the topic.

    2.  Use Adjectives


When it comes to writing headlines. Adjective plays a vital role. Proper use of adjectives in headline are attention-grabbing and easily get clicked.

Some interesting adjectives that work like charm include:

    Secret
    Strange
    Smart
    Easy
    Effortless
    Simple
    Incredible
    Free

You have to be very careful when using adjective in headline. Always avoid subjective claim like "The leading ......" or "The only one ......" or "The number one ......" etc. Most people use it, but they are futile; like claiming your post or blog is the best in the world. Sounds weird, right?

These sorts of claim are tempting really, but it will demote your credibility if the post doesn't truly provide what the headline advertise.

3.  The Why, What, When, and How Headline

These are trigger words and they are the widely used format in writing a captivating headline. They are very effective in creating curiosity that get clicked.

The headline says why something is important or relevant or secret or effective, but to find out exactly why that is, you have to read the article.

    Why people struggle to get what they want?
    Why you need to write great headline?
    Why You Will Fail at Blogging
    What you need to succeed at blogging?
    When should you monetize your blog?
    How to write compelling headline that people can't resist
    How to reduce your blog bounce rate fast

  4.  Urgent Headline

An urgent headline calls for immediate attention. Great headlines that demand attention use some type of time aspect to drive interest.

"Write Better Headlines" is not nearly as compelling as "Write Better Headlines Today!". Just one word can trigger a sense of urgency and make all the difference.

Give your headline a sense of urgency by using a time element. Use a specific unit of time in your headline, such as:

    Now
    Today
    Soon
    Day, Month, year

People are generally prone to take action if they know they're running against time. But make sure you withdraw your offer at the stated time. If you're going to extend the deadline, you should provide a better reason because your credibility is at stake.

  5.  Be Specific


I noticed that most of the highest converting headlines on the web are more specific. Qualifying your headline with specific phrase tends to be targeted and catchy.

Let's say you are above 40years of age and you read this two headline:
"Health tips"
"Health tips for people above 40years"
Which one will you read first? The later, right?

Instead of writing "100+ ways to do something," write something like "108 ways to do something." "Get a T-shirt for less than $20" is not as catchy as "Get a T-shirt for only $14." Let's people easily know what is in your post for them. Your headline must relate to a specific offer or to a specific result or benefit. The headline can't be vague or ambiguous.

  6.  Keep it Short and Clea
r

What is the ideal length for headlines?
Eight words or less is a good rule of thumb. Shorter headlines are easy to share especially on Twitter where your tweet are limited to only 140 characters.

It is difficult to stick to this rule, but nonetheless, it’s a good one. Fewer words make greater impact.

There’s no reason why you should use long tail keyword phrase for SEO sake, short keyword phrase if appropriate. Remember the article needs to be read by people, and not just search bots. So if your headline looks too forced it’s going to be a big turn-off for your audience.

Consider the following two examples:

10 things that will make people not to read your blog again
AND
10 Killer ways to suck your blog

Notice any difference? That's the effectiveness of brevity!
There are times where long words works well. But trying to stick up with shorter words have always be the best and effective ways to write compelling headlines.

  7.  Controversy Headline

Taking a stand on a big issue or vocalizing your opinion can be very effective at attracting readers and increasing click-through rates. If you can write a headline that go against a bad product or popular practice, write it. If you find out a way of doing things that people will find it hard to believe, get your computer ready!
Controversy is one of those things that tends to pique people’s interest. But you have to back these types of titles up with posts that reflect the title and with good reasons.

Avoid race, religion, and extremely sensitive topics so you don’t earn a bad rep or offend a lot of people, because when you create controversy, you'll attract opinions, questions and different reactions.

  8.  News Format


People are pre-disposed to seek out what is new and different in their environment. To give readers a reason to read your blog content, your headline must say something she never heard before. If your headline make her feel "i already know about that." that's a big turn-off.

Putting your headline in terms of a story, news or announcement, have always works great. Headline starting with "Introducing", "At last", "Finally", "New", "Now", "Just released" and so on are all tested winners.

If you want to get inspiration, look at the cover of magazines or news paper. Those editors sure know how to write compelling headlines. They know the secret of headlines: it’s the headlines that sells. Same thing with your blog headlines.

  9.  Make BIG Claims

When you have a "Wow" level content, share it! Making big claims have prove to be very effective in driving people attentions. People who don't really need your post will also like to check it out.

When making big claims, you have to back up your claims with tangible proof or testimonial if you don't want to run a risk of loosing your readers interest.

Examples:

    How i make $40,000 less than a month using [blank]
    You don't have to be a runner to win a marathon


  10.  Make a Promise


Will you teach your readers how to learn a new skill? Will you persuade them to do something they never done before? Will you unlock an ancient mystery? Whatever the story will do, it should have some use to the reader.

For your reader to see value in your copy, you must show how it will help him. Remember that people buy because they want a result. Make your headline have your big promise in it - and guarantee it!

    Sell your house in a day
    Get rid of that carpet stains once and for all
    How to burn fat until you hit your ideal weight - GUARANTEED!

To make your promising headline, simply speak to the issue which is foremost in your reader’s mind - the solution he have been craving for. Always deliver what you promised.

  11.  Ask a Question


Questions are a good way to arouse readers curiosity, effective at getting readers to leave comment, powering them to want to find out more and give them a need to read the full story.

    Why doctors don't get sick?
    Would you travel 1000miles for this girl?
    Do you make this blogging mistake?

When you ask a question, those who read it are wired to respond. But these is also risky if the readers immediate answer is 'no'. A question like "Do you want to know my blogging secrets?" might get a 'no' as answer. Likewise "Do you need a web designer?" can get skipped. Asking rhetorical question like "How do you know when it is time to hire a web designer?" sounds enticing.

Further Headline Writing Tips
    Write it first: Can you start writing an article without knowing the main idea or concept behind it? Can you write it without knowing what it’s about? Of course not. Don't save the headline for last. You must write it down first so as to know where the article is headed.
    Write different version: Don't just go with the first attempt. Write down 5-7 different styles and experiment the one that sound enticing by saying it loud or re-check it with a fresh mind after few hours to see how it will appeal to your audience.
    Use bold font size: Make sure the font size for your headlines is big and clear enough so people know they’re headlines. You’ve spent time creating headlines you can be proud of, won't it be a waste if people can't read them?.
    Check for boring headlines: Go through your blog archives to see if there is any headline that turn-off readers. If you find some, change it to give room for more people to read.

People don’t want to be tricked into reading something boring, they want to be drawn into something exciting. Don't make them feel depressed after reading your copy. The time spent on crafting your great headline, should also be spend on creating great content to back it up.

There’s a lot more you can study when it comes to headlines, but practice is more important than study, so get out there and create articles that need headlines, and incorporate the above best practice.

फसेबूक ले Like र Share buttons first चोटी change गर्यो !!

It won't be wrong to say that the Like button is the soul of Facebook, the popular social networking service. The Like and Share buttons aren't just confined to the Facebook website but extend much beyond it across the Internet allowing users to share and recommend content driving referral hits.

For the first time, Facebook has decided to give these buttons a makeover. The social network says that it's already seeing a 'favourable increase in Likes and Shares with the new design' and that it would be rolling these buttons out to everyone in the next few weeks.

The new buttons sport a brighter shade of blue with white 'Like' text in a new font and a Facebook 'F' logo instead of the thumbs-up symbol.

Facebook will automatically upgrade the new design of the buttons part of the roll out for websites currently using the old ones. The new design allows websites to use the Like and Share button together in convenient ways.

Alicia Ann Lynch: Boston Marathon Bombing Halloween Costume Draws Death Threats; Social Media User Gets Fired - Hoax or Fact?

Alicia Ann Lynch is the latest name to draw death threats on Twitter over a joke, which, according to many social media users, was not funny. Alicia posted photos of herself in a Boston marathon bombing Halloween costume. Is the news some attention grabbing hoax or for real?

The proliferating marathon bombing Halloween costume (click here to see the photo) shows a smiling young lady in a blue marathon shirt marked 739. Her arms and legs are painted with fake blood, making some people shudder over the memory of the Boston tragedy.   

"Totally saw this costume last night. RT A woman who dressed up as a Boston bombing victim," Twitter user @chachkevitch posted. The RT is understood to be "retweet," for the others to react or simply retweet the photo. Many others have done the same.

The latest developments indicate Alicia's parents and she herself have received death threats over the joke. Screen captures of her Halloween photo are widespread on Twitter and Instagram, and it remains visible even after she has cancelled her social media accounts.

"Plz stop with the death threats towards my parents. They did nothing wrong. I was the one in the wrong and I am paying for being insensitive," Alicia Ann Lynch was quoted as saying in a screen capture report. She has also reportedly tweeted about having lost her job over the incident.

"Girl Who Wore Boston Marathon Bombing Victim Costume Is Lowest Form Of Life Possible," tweets @txsunshinegrl04.

"To the girl that thought it would be a good idea to dress up in a marathon bombing victim costume, I hope you get hit by a train," tweets @ajorge4793.

The controversial Halloween photo may have sparked some very angry remarks, but others have shown they can react without angry words and imply disgust at the same time. Some just have to point out one word to describe the "bombing victim" costume.

"It really disturbs me that people would find a marathon bombing victim halloween costume funny, clever or appropriate," tweets @TiarraNorcross.

"This is disgusting. It's not 'too soon,' its WRONG," tweets @SashaWithLuv.

Social media users often fail to separate the act from the doer, as others believe there should be no separation at all. However, there are others who care more about pointing out what is wrong, instead of giving people a taste of their own (perceived) offence.

The Halloween photo, if not displayed in Facebook, Twitter, and Instagram, is linked - permanently - in some users image host accounts.

"How's everyone feel about this girls Marathon Bombing costume? http://tinyurl.com/n7qppvr," tweets @thejustinmac. 

There's a lesson for social media users here. Think twice before you post. This is not the first mistake ever made on Twitter or anywhere online. But there has been a pattern, and some people are not too forgiving. This Twitter user (@TheTwidster) who claims to be a Bostonian, has a message for Alicia Ann Lynch:

"As a Bostonian, I forgive you. I am glad that you have not killed yourself, and I seriously hope you learned your lesson."
