Art and Technology - Essay Example This section of the Tapestries provides information dated back to a time when the battle had not taken place. The choice to explore the Battle of Hastings is critical to gaining knowledge that relates to the fact that the battle marked the very last time that the Island was conquered by a foreign power. This section therefore provides a one-time conflict that any scholar throughout the world ought to know about. Ubiquitous is defines as act of being everywhere, all at the same time (Smith 53). Ubiquitous computing is a form of computing paradigm that is considered to be the next big thing in the computer industry. Every day is characterized by a number of ubiquitous computing elements and activities. One of these is mobile devices in the context of Ubiquitous computing. Mobile development has developed mobile capacities and capabilities to a more complex aspect, allowing mobile devices to handle user environments; like setting up reminders based on the location of the phone. Biometrics is another ubiquitous computing observed. It is a privacy control mode of computing characteristic to many firms and organizations. Biometrics employs physical characteristics, and a user can be identified by simply touching the ubiquitous device. Ubiquitous networking is another example. Computing activities and performance heavily dwells on networking. Transmitted computing networks are not visible yet they are actually put into use. Ubiquitous networks range from low power, short range, ad hoc to wireless networks and systems (Smith

Gibberellic Acid In Fruits Essay Example | Topics and Well Written Essays - 1500 words

Gibberellic Acid In Fruits - Essay Example These enzymes include cytochrome P450 monooxygenases, terpene synthases (TPSs) and 2-oxoglutarate-dependent dioxygenases (2ODDs). It is used in the enlargement of ovary without any effect on the underlying ovary structure. Commercially, Gibberellins is used in Grapes farming to promote the growth of a variety of fruit crops. The effects of plant hormones are complicated biologically and biochemically hence they are not fully understood because of their unique effects on different plants. Gibberellins also known as gibberellic acids were first discovered by Eiichi Kurosawa, a Japanese scientist while investigating bakanae, the â€Å"foolish seedling† infection in rice (Yeoshua, 2005). The United States developed the interest about gibberellins after the Second World War. The Japanese rice farmers had long known of ‘foolish seedling’ a fungal disease that causes rice plants to grow taller and eliminate seed production. Later, the plant pathologists established that these symptoms in rice plant were induced by a chemical secreted by a pathogenic fungus, Gibberella fujikuroi. Japanese scientists started culturing this fungus in the laboratory and analyzing the culture filtrate in 1930s that enabled them to obtain impure crystal of two fungal â€Å"compounds† possessing plant growth promoting activity (Thompson, 2008). Teijiro Yabuta and Sumuki named one of these compounds gibberellin A because they isolated it from the fungus  Gibberella. In 1950s scientists from Tokyo, University isolated and classified three different gibberellins from gibberellin A sample, which he named them gibberellin A1, gibberellin A2  and gibberellin A3 (Cline & Trought, 2007). This system for numbering gibberellins used in the past 50 years was based on this initial nomenclature of gibberellins A1  (GA1), GA2, and GA3. Gibberellins (GAs) are
