– Aspirin – The most common analgesic used today to treat fever, arthritis and pain; possible side effects can include nausea, heartburn or development of bleeding ulcers. Aspirin prevents stomach upset. Reye’s syndrome may develop if aspirin is given to children with the flu or chicken pox. This disease is characterized by vomiting, swelling of the brain and liver, difficulty with mental functioning, and can often lead to death. People with liver damage should also avoid using aspirin.
To understand why, just think about how heat is conducted through the air. It is carried via molecules, which constantly collide with each other and scatter the heat in all directions—forwards, sideways and even backwards. That fundamental inefficiency makes conductive heat relatively sluggish (radiant heat, by comparison, can travel at light speed as infrared radiation). The same sluggishness holds for heat moving through a solid. Here, phonons (packets of acoustic vibrational energy) carry the heat much like molecules in the air, allowing it to scatter in all directions and slowly disperse. “It's a little bit like, if you take a drop of food coloring and put it into water, it spreads,” says Keith Nelson, Duncan’s advisor at MIT. “It doesn’t just move straight as an arrow away from where you put the drop.” But that is precisely what Duncan’s experiment suggested. In second sound, the backscattering from phonons is heavily suppressed, allowing heat to shoot forward. “That’s the way wavelike motion behaves,” Nelson says. “If you’re in a pool and you launch a water wave, it will leave where you are.… But it’s just not normal for heat to behave that way.”
Researchers have found that THC changes the way in which sensory information gets into and is processed by the hippocampus. The hippocampus is a component of the brain’s limbic system that is crucial for learning, memory, and the integration of sensory experiences with emotions and motivations. Investigations have shown that neurons in the information processing system of the hippocampus and the activity of the nerve fibres in this region are suppressed by THC. In addition, researchers have discovered that learned behaviours, which depend on the hippocampus, also deteriorate via this mechanism.
Text to speech enables brands, companies, and organizations to deliver enhanced end-user experience, while minimizing costs. Whether you’re developing services for website visitors, mobile app users, online learners, subscribers or consumers, text to speech allows you to respond to the different needs and desires of each user in terms of how they interact with your services, applications, devices, and content.
It is no wonder that Duncan, a graduate student at the Massachusetts Institute of Technology, could not quite believe his eyes. To ensure that he had not made a mistake, he quadruple-checked everything within his set-up, ran the experiment again, and took a mental-health break. “I tried to get some sleep, knowing that I wouldn’t be able to tell if the experiment was successful or not for several more hours, but I was finding it pretty difficult to shut down for the night,” he recalls. When Duncan’s alarm went off the next morning, he ran to his computer (still in his pajamas) and crunched the new measurements only to confront the same result: Heat had still moved impossibly fast.

And it certainly is not supposed to do that at such high temperatures. Marzari, who predicted the phenomenon at almost the same time as Chen, was therefore fairly confident that it would prove valid. Even so, he was less certain that second sound would be seen at the foreseen high temperatures. “If you had asked me to bet my mortgage on the existence of this effect, I would have said yes,” Marzari says. “But the question is always does it happen at 100 Kelvin, 20 Kelvin or 0.1 Kelvin?” Duncan’s experiment found the effect at 120 Kelvin—more than 10 times higher than previous measurements. “Nobody ever thought that you would actually be able to do this at such high temperatures,” says Venkatesh Narayanamurti, a research professor of technology and public policy at Harvard University who was not involved in the study. “In that sense, it breaks some conventional wisdom.”
Methamphetamine releases high levels of the neurotransmitter dopamine, which stimulates brain cells, enhancing mood and body movement. It also appears to have a neurotoxic effect, damaging brain cells that contain dopamine and serotonin, another neurotransmitter. Over time, methamphetamine appears to cause reduced levels of dopamine, which can result in symptoms like those of Parkinson’s disease, a severe movement disorder.

It also suggests that the finding might find a practical use in the future. Not only is the temperature far more practical than the cryogenic chill required to work with the previous findings, but graphite is a commonplace material—two characteristics that might help engineers overcome the daunting issue of heat management in microelectronics today. Just imagine if heat rushed away at the speed of sound, allowing materials and devices to cool much more rapidly. Such a feat surely would allow engineers to build smaller, more efficient microelectronics. With this in mind, Narayanamurti (who worked on second sound when he was at AT&T Bell Laboratories from 1968 to 1987) suspects that the field soon flourish once again. “If I were still at Bell Labs, I would have people doing experiments on it because it will be important 10, 15 years down the road.”

أثناء هذه السنوات فى تدخين الحشيش والخمرة كنت أسمع عن البرشام و أدوية الكحة المخدرة و لكني كنت أنظر باحتقار لهؤلاء الذين يستخدموا هذه الأشياء لأنها ليس على المستوى، وأنهم ناس بيئة. ولكني بعد سنوات قليلة بدأت في تجربة البرشام ووجدت أنها دماغ روشة جداً وإني مختلف حتى في استقبالي لهذه المخدرات فأنا أتعاطاها ولكن بمستوى خاص وبأسلوب راقي. في هذه الفترة بدأت المغامرة تأخذ شكلاً أكبر في حياتي. بدأت السرقة مع أصدقائي بأسلوب منظم ومنتظم. سرقنا الكماليات الداخلية للسيارات مثل الكاسيت والسماعات وأجهزة الصوت أو أي شيء يوجد داخل السيارات. وأصبح التجمع بشكل يومي، فنقوم بتعاطي البرشام المخدر ثم نبحث عن السيارات في المناطق الهادئة ونقوم بكسر الهواية لفتح السيارة وسرقتها. كانت المغامرة في شدتها لأننا كنا نعلم أن الشرطة تبحث عنا و تريد القبض علينا. كنا نحاول تضليلهم بطرق عديدة و أساليب مختلفة ثم نستمتع بنجاحنا بشرب المخدرات والسهر والفلوس والبنات. ولكن بعد وقت ليس بكثير تم القبض علينا في تشكيل عصابي لسرقة محتويات السيارات.

Sensations and feelings change much more dramatically than the physical signs. The user may feel several different emotions at once or swing rapidly from one emotion to another. If taken in a large enough dose, the drug produces delusions and visual hallucinations. The user’s sense of time and self changes. Sensations may seem to cross over, giving the user the feeling of hearing colours and seeing sounds. These changes can be frightening and can cause panic.
