Do not Underestimate the Tingling

Some people must have experienced numbness when sitting cross-legged for too long or fall asleep with his head crushed. This condition also occurs when pressure on the nerve that goes right. However, the numbness will go away when the pressure is not there anymore.
Pins can also be indicative of many diseases, such as diabetes mellitus, hypertension, pinched nerves, impaired blood flow in the peripheral blood vessels, and blood disorders. There are times when those who have not known to have diabetes, tingling may be an early symptom of diabetes known.
Paresthesia or numbness is often a symptom of chronic neurological disease or traumatic nerve damage. The cause is a disorder that affects the central nervous system such as stroke and mini stroke, multiple sclerosis, transverse myelitis, and encephalitis.
Tumors and vascular lesions of the brain or spinal pressure can also cause paresthesia. Neurological syndromes such as carpal channel syndrome (CTS) can damage the peripheral nerves and cause paresthesia accompanied by pain.
Here are a number of diseases characterized by symptoms of tingling.

1. Diabetes mellitus (DM)
In patients with DM, tingling is a symptom of damage to blood vessels. As a result, blood flow in the nerve endings is reduced. This condition can be overcome by controlling blood sugar levels closely, also taking drugs such as gabapentin, vitamin B1 and B12.
2. Stroke
Tingling can be a sign of a mild stroke. Usually caused by blockages in blood vessels in the brain, resulting in damage to local nerves. Other symptoms that occur: numbness half body, half body paralyzed, blind one eye, difficulty speaking, dizziness, double vision and blurred.
Symptoms last a few minutes or less than 24 hours. Usually occurs during sleep or just waking up. This condition should be treated because it can develop into a severe stroke.

3. Heart disease
Tingling neuropathy is not only due to pressure, but because of cardiac complications with her nerves. In patients undergoing cardiac valve surgery installation, there are blood clots that stick. Clot that can be carried by the flow of blood to the brain, causing cerebral embolic.
If the blockage in the brain regions that regulate the sensory system, the patient will feel a tingling right. If the local governing motor system is also affected, the tingling will be accompanied by paralysis.

4. Infections of the spine
This causes the body from the navel downwards can not be moved. Patients could not control urination. Bowel movement was difficult. This disease called myelitis (inflammation of the spinal cord). Level of recovery depends on the damage. Can recover some, but there is also a paraplegic.

5. Rheumatism
This disease can cause tingling or feeling thick. In this case due to a pinched nerve at the hinge joints, such as the wrist joint, change shape. Tingling symptoms usually disappear when cured rheumatism.

6. Spasmofilia (tetani)
Symptoms of tingling can also be a sign of disease spasmofilia (tetani). The disease is caused by calcium ion levels in the blood decreases. The reason is the decrease of carbon dioxide tension in the lungs. Other symptoms: leg cramps, insomnia, emotional instability, fear, weakness, headaches or migraines, and lost consciousness.

7. Guillain-Barre syndrome
Tingling could be one indication of this disease. Marked symptoms of high fever, cough, and shortness of breath. Also followed by tingling and numbness. Tingling sensation usually felt in the whole body, especially on the tip of the toes and fingers due to virus attacks the peripheral nervous system.
If things were not addressed, will continue to attack vital organs. As a result, the patient felt shortness of breath and was paralyzed on the entire body.

8. Cytomegalovirus (CMV)
There is a tingling sensation that preceded severe flu. Tingling will increase in intensity starting from the tip of the finger, creeping up to the navel. Patients may simply feel numb or to difficulty walking, means inflammation of the spinal cord is taxable. This is due to virus attacks, typically cytomegalovirus.

Bloggers, now we already know that tingling sensation should not be left alone. Let's keep the health, because health is good. If healthy, we can move comfortably, including blogging. Is it true?

New Name in the Periodic Table of Chemical Elements

Blogger Friend, surely you're all familiar with chemical terms, chemistry, and so on. Especially during high school that used to sit in science class. Chemistry is arguably one of the lessons that 'maybe' less liked by students, because the chemistry lesson arguably one of the lessons are hard to understand. If that were the case, this could be bad news. Why? Due to the already complicated chemistry has now got a new comer in the periodic table of elements. There are three additional new elements were added in the periodic table of elements. These three names have been approved by the General Assembly of International Union of Pure and Applied Physics (IUPAP). Approval was committed in the meeting by the General Assembly which consists of 60 people at the Institute of Physics (IOP), London, Saturday 5 November 2011 that then. These three elements are named Darmstadtium (Ds), Roentgenium (Rg) and Copernicium (Cn), each is numbered 110, 111 and 112.

Head of IOP and the Secretary General of IUPAP, Dr Robert Kirby-Harris, as quoted by the Daily Mail last Saturday said the naming of this element has been approved in consultation with physicists from around the world and we are pleased to see them introduced in the periodic table of elements.

In earlier publications Saturday, LiveScience stated that the three elements of the new element called "superberat" or transuranium. This element exists only in the laboratory, not in nature, once shed quickly become another element and difficult to learn. Not much is known about that element. These three elements have long been found. However, indirect naming must be done in accordance with the agreement due to organizational scientists. Therefore, the three elements can only be added to the Periodic Table.

In general, an element named after its discoverer, the place is found or the name of honor. Copernicium for example, was created February 9, 1996 under the name ununbium. The name did not change until 2009 when the existence of an element has been demonstrated. The name was taken in honor of Copernicus and Copernicus, the first scientist to claim that the Earth around the Sun.

While Roentgenium found December 8, 1994 with the original name unununium. Roentgenium name then used as a tribute to the services of Wilhelm Conrad Roentgen, the scientist who detects X-rays and won the physics Nobel in 1901.
Darmstadtium created by Peter Armbruster and Gottfried Munzenberg with names beginning ununnilium. The name is taken Darmstadtium conducted at the facility for the manufacture of the GSI Helmholtz Centre for Heavy Ion Research in Germany, located near the city of Darmstadt.

Having succeeded in giving the names of three elements, the scientists are now trying to name the elements 114 and 116 that have been added to the periodic table of elements that last July. Its official name will soon be introduced some time to come.

Eat Dark Chocolate = Exercising?

Good news for my friends who do not like exercise. What is it? Now there is another way that 'may' is much more comfortable that the effect is not lost through exercise. Want to know? Curious? The answer is to eat chocolate. Why? Not good? we do not need to tired to exercise, do not need to be bathed in sweat, quite simply by eating chocolate. This is not true? Lest lie? First patient, do not protest!

You could say that chocolate is a favorite food of all ages. Foods that this one was known to have a delicious flavor. People who do not like chocolate 'maybe' you could say 'weird'. Some time ago, a study has brought out another one for the health benefits of chocolate. Previously found a variety of chocolate's health benefits. But this is different to that before. A recent study revealed that eating dark chocolate has health benefits for our body, which is equivalent to people who do sports activities.

A researcher from Wyne State University, Dr.. Moh Malek, focused his research on mitochondria. Mitochondria are the energy generation sources that produce energy in cells. In his research, he discovered the existence of a plant compound found in cocoa or cocoa called epicatechin. These compounds are able to provide stimulation to the muscles so that the response generated is similar to sports activities. Dr. Malek explained that mitochondria produce the energy used by cells in the body. The more mitochondria means the greater the energy produced. Thus, the more work that can be done by the body.

This study used rats as experimental. Research conducted by Dr. Malek is using a type of cocoa epicatechin administered to rats twice a day. This is done regularly and continuously for 15 days. At the same time, other rats that underwent exercise treadmill for 30 minutes per day. From both experiments, Dr. Malek found that rats that ate only epicatechin has the same performance as a treadmill exercise rats.

The researchers hope these findings can be used as an alternative to fight age-related muscle wasting.
"It appears that epicatechin treatment combined with exercise can be a means to offset the aging of muscles," adds Dr. Malek.

How is my friend? I am not lying, right? Now to select which one? Want sports tired, perspiring, it took the sacrifice of time or enough to eat chocolate? If I so choose both, exercise and eating chocolate ....

How Much We Use Brain?

Basic pinhead! Such statements are usually uttered by someone who is upset face stupidity of others. In fact, as quoted by the journal Intelligence, on the basis of the results of research conducted at Virginia Commonwealth University, noted that the intelligence of a person not related to brain size has. Whether it's big or small brain size, has nothing to do with intelligence. But the brain size of this will affect the other functions. As examples of people who live in the Antarctic region in general have large brains. It is necessary to support the function of vision. As we know, in Antarctica, which is part of the north end gets very little sun exposure because the sun is rarely seen. Therefore, the weather there tends to dim. This is why they need more visibility to be able to look around than people who live in khaulistiwa.
Different things happen to people who live in the Micronesia region. Most of them had a relative brain size smaller. Women have smaller brains than men, about 11-12 percent. However, this does not mean men are smarter than women.
"Only the brains of different buildings. Areas of the brain associated with intelligence in men with different areas of the brain associated with intelligence in women. There are at least two different brain architectures that lead to the same level of intelligence between men and women," said Prof.. Richard Haier, a consultant neuroscience at the University of California, Irvine.

Need Lots of Energy

Another misperception that had circulated in the community for decades is the opinion which states that most new human brain uses about 10 percent, while most of the brain has not been used or otherwise unemployed. Some experts are then denied the presumption. One of them is Barry Gordon, a neurologist from Johns Hopkins School of Medicine, in Baltimore, USA.

In addition to Barry, John Henley, brain specialists from the Mayo Clinic, Rochester, Minnesota, United States stated that the evidence shows that our brain uses 100 percent, all day. When we sleep, frontal cortex areas that control high-level thinking and self-awareness, or somato sensory area which helps us to feel the surroundings remain active. In addition, he also stated that sometimes the brain that we use is no more than 10 percent, but all parts of our brain functioned every day. So no one allowed to remain unemployed. Every part of the brain has the function of each. For example, frontal lobe associated with the motor, memory, cognition, and language, and cerebral cortex that has the task of learning new information, make decisions, etc..
Therefore, if every time we use every part of the brain simultaneously, it will require a lot of body energy. Most of our body's energy, about 20 percent, is allocated for normal brain function. It was meant to do other things such as walking, breathing, eating, digesting food, and other vital activities, we will lack energy.

Thousand Tera

Physically viewed our brain is a soft organ, mostly composed of water (78 percent), fat (10 percent), and protein (8 percent). Beyond the physical aspects, in fact many scientists are only able to open up a bit of mystery that envelops the brain. Until now, it is not clear about the dreams, the relationship between the conscious and subconscious, the relationship between brain and mind, brain and soul, the funds are still many more, including how much brain capacity we have.
In an age-paced computerized, as now, the human brain is often compared to the "brain" is actually a computer that man's own creation. How hell, why even compared to homemade?
In the human brain there are about 100 billion nerve cells, where one another have a connection. Experts suspect, in many connections that the data (memory) is stored. It is estimated that our brain's capacity to store terabytes of data between 1-1000 terabyte.

Bloggers, in fact the most important thing is not on the size of our brains. Whether it's big or small, the most important thing is that we must love him. The trick to give him healthy food, exercise regularly, use it only for things that are positive and beneficial for others. And do not forget is to not use excessive brain. Rest when tired. The brain is also like a muscle. He also can wear out and need to relax, especially if you have to concentrate on the same task in a long time. To revive, Dr. Marc Berman suggested for a moment the streets in a city park between the trees big or look at the beautiful green gardens, rather than going into a busy shopping center.

"Enjoying the natural beauty of memory will improve performance by up to 20 percent. Instead, go to crowded places instead will add to the anxiety," said researchers from the Rotman Research Institute in Toronto, Canada.

Bloggers, already described?! Never force the brain. If you are tired, it breaks. Stop all activity for a moment to rest, so that fresh anymore and certainly can blog again ...

Apa itu CAPTCHA

Saya sangat yakin bahwa Sobat Blogger pernah mendengar atau mungkin melihat / membaca kata “CAPTCHA “. Mungkin diantara Sobat Blogger ada yang bertanya-tanya, Apa itu CAPTCHA ?
CAPTCHA merupakan kependekan dari Automated Public Turing test to tell Computers and Humans Apart. Istilah ini diciptakan oleh Luis von Ahn, Manuel Blum, Nicholas J. Hopper, dan John Langford pada tahun 2000. CHAPTCHA merupakan jenis respon tes yang digunakan dalam dunia komputasi yang bertujuan untuk memastikan bahwa user adalah human atau manusia, dan bukan robot. Prosesnya biasanya melibatkan sebuah server yang meminta user untuk menyelesaikan sebuah tes sederhana yang sudah diidentifikasi oleh server tersebut. Dalam hal ini, computer lain diasumsikan tidak mampu untuk memecahkan tes yang dimaksud, sehingga setiap user yang memasukkan solusi yang tepat diduga sebagai manusia. Jenis umum dari CAPTCHA mengharuskan user untuk mengetik huruf dan atau angka dari gambar terdistorsi yang muncul di layar.
Mungkin ada diantara sobat blogger yang bertanya-tanya, mengapa harus menggunakan CAPTCHA? Sebenarnya apa fungi CAPTCHA? Berikut ada beberapa fungsi dari CAPTCHA.
Mencegah Spam Komentar di Blog
Seperti kita ketahui bersama, ada sebagian Blogger yang suka mengirimkan komentar palsu. Ini dilakukan dengan menggunakan sebuah program. Biasanya tujuannya adalah untuk meningkatkan rangking pada mesin pencari. Ini disebut sebagai spam komentar. Disinilah peran CAPTCHA diperlukan. Dengan menggunakan CAPTCHA, manusia hanya dapat memasukkan komentar di blog. Tidak perlu untuk membuat pengguna mendaftar sebelum mereka memasuki komentar.
Melindungi Situs Pendaftaran
Beberapa perusahaan (Yahoo, Microsoft, dll) menawarkan layanan email gratis. Sampai beberapa tahun yang lalu, kebanyakan dari layanan ini menderita jenis serangan tertentu: "bot" yang akan mendaftar untuk ribuan akun email setiap menit. Solusi untuk masalah ini adalah menggunakan CAPTCHA untuk memastikan bahwa hanya manusia yang akan memperoleh akun email. Secara umum, layanan bebas harus dilindungi dengan CAPTCHA untuk mencegah penyalahgunaan oleh program otomatis.
Mencegah Serangan Kamus
Selain hal diatas, CAPTCHA juga dapat digunakan untuk mencegah terjadinya serangan kamus dalam sistem sandi. Idenya sederhana: mencegah komputer dari mampu iterate melalui seluruh ruang dari password dengan mengharuskan untuk memecahkan CAPTCHA setelah sejumlah login gagal.
Search Engine Bot.
Worms dan Spam
CAPTCHA juga menawarkan solusi yang masuk akal terhadap cacing email dan spam: ". Saya hanya akan menerima email jika saya tahu ada manusia di balik komputer lain" Beberapa perusahaan sudah memasarkan ide ini.
Setelah kita mengetahui fungsinya, sekarang kita akan membahas bagaimana aplikasi CAPTCHA ke website.
Jika website Anda membutuhkan perlindungan dari spammer, Anda dapat menggunakan CAPTCHA. Namun dalam penggunaanya, ada beberapa pedoman yang sangat disarankan, antara lain :
Aksesibilitas
CAPTCHA harus dapat diakses, CAPTCHA hanya didasarkan pada teks membaca - atau persepsi visual-tugas - mencegah robot atau mesin dari mengakses sumber daya yang dilindungi. Selain berbentuk visual, sekarang CAPTCHA juga ada yang berbentuk audio. Hal ini dilakukan untuk memudahkan bagi user tunanetra.
Security Image Gambar
Dari teks harus terdistorsi secara acak sebelum disajikan kepada user. Banyak implementasi CAPTCHA menggunakan teks terdistorsi, atau teks dengan hanya distorsi kecil. Implementasi ini rentan terhadap serangan otomatis yang sederhana.
Keamanan Script
Membangun sebuah CAPTCHA yang aman tidak mudah. Selain membuat gambar terbaca oleh komputer, sistem harus memastikan bahwa tidak ada cara mudah sekitarnya di tingkat script.
Meskipun kelihatannya aman, sebuah CAPTCHA masih mempunyai celah yang mungkin masih bisa ditembus, diantaranya :
Mengeksploitasi bug dalam pelaksanaan yang memungkinkan penyerang untuk sepenuhnya bypass CAPTCHA
Meningkatkan perangkat lunak pengenalan karakter, atau
Menggunakan murah tenaga manusia untuk proses tes.


Sobat Blogger, kita sudah membahas tentang fungsi, pedoman pemasangan, sampai celah yang mungkin bisa ditembus. Semoga coretan yang sedikit dan jelek ini bisa bermanfaat bagi kita semua. Silahkan dikoreksi, dan jangan lupa tinggalkan komentar.

Versi Terbaru Opera Mini 6.5 dan Opera Mobile 11.5

Opera, salah satu perusahaan peramban web raksasa telah meluncurkan dua produk terbaru mereka dalam event bertajuk “Up North Web” 2011 di Holkenkollen, Oslo Norwegia, pada tanggal 11 Oktober 2011 kemarin. Dua produk terbaru ini adalah versi terbaru mobile browser, yaitu Opera Mini 6.5 dan Opera Mobile 11.5. Kedua browser tersebut sudah bisa didownload secara gratis. Bagi pengguna ponsel Android, bisa mendownload melalui m.opera.com, sedangkan untuk platform yang lainnya akan segera hadir dalam beberapa hari ke depan.
Sebenarnya apa sih yang membedakan dua versi ini dengan versi terdahulu? Salah satunya adalah adanya fitur data usage. Dengan adanya data usage, pengguna bisa melacak besarnya pemakaian data saat membuka suatu situs. User bisa melihat berapa besarnya data yang dihemat oleh server Opera dari halaman situs aslinya. Seperti kita ketahui bersama, urusan hemat-menghemat data adalah salah satu kelebihan yang ditawarkan oleh opera mini dan mobile. Mungkin ini tidak penting untuk Anda yang browsing di rumah, tapi ini akan sangat terasa bagi pengguna dengan kartu SIM atau buat yang bepergian ke luar negeri dan tak punya pilihan fitur roaming yang murah.
Selain adanya fitur data usage, versi terbaru ini juga mengalami beberapa perbaikan dibanding dengan versi sebelumnya. Diantaranya adalah mesin rendering Presto versi terbaru, peningkatan kemampuan jaringan, dukungan HTML5 mikro data dan juga penghematan memori untuk pemakaian JavaScript. Selain itu, untuk Opera Mobile yang terbaru sudah mendukung inline video pada Honeycomb. Khusus untuk Anda pengguna Android, versi terbaru ini akan lebih memanjakan anda. Kedua versi terbaru ini lebih terintegrasi dengan system operasi Android. User dapat mengimpor “bookmarks” dari browser bawaan Android serta membuat “shortcut” dengan hanya dengan satu langkah saja.
