Self-assembled nanocrystals discovered in Chelyabinsk meteorite
Current interest in nanomaterials is focused mostly on artificial materials fabricated for various applications. However, naturally occurring nanocrystal arrays, like those recently found in the meteorite that fell near Chelyabinsk in Russia on 15 February, 2013, can provide some new insights into the nature of nanomaterials, including the conditions for their natural occurrence. Here we report...
متن کاملChelyabinsk airburst, damage assessment, meteorite recovery, and characterization.
The asteroid impact near the Russian city of Chelyabinsk on 15 February 2013 was the largest airburst on Earth since the 1908 Tunguska event, causing a natural disaster in an area with a population exceeding one million. Because it occurred in an era with modern consumer electronics, field sensors, and laboratory techniques, unprecedented measurements were made of the impact event and the meteo...
متن کاملTraveling ionospheric disturbances triggered by the 2009 North Korean underground nuclear explosion
Underground nuclear explosions (UNEs) can induce acoustic-gravity waves, which disturb the ionosphere and initiate traveling ionospheric disturbances (TIDs). In this paper, we employ a multi-step and multi-order numerical difference method with dual-frequency GPS data to detect ionospheric disturbances triggered by the North Korean UNE on 25 May 2009. Several International GNSS Service (IGS) st...
متن کاملanalysis of power in the network society
اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...
15 صفحه اولGeneration of Artificial Acoustic-Gravity Waves and Traveling Ionospheric Disturbances in HF Heating Experiments
We report the results of our ionospheric HF heating experiments to generate artificial acoustic-gravitywaves (AGW) and traveling ionospheric disturbances (TID),whichwere conducted at theHigh-frequencyActiveAuroral Research Program facility inGakona, Alaska. Based on the data from UHF radar, GPS total electron content, and ionosonde measurements, we found that artificialAGW/TID can be generated ...
