history‚ titled’ A Journey In Time: The Remarkable Story of Seiko’ (2003)‚ Seiko is a Japanese word meaning success. The first watches produced under the Seiko brand appeared in 1924. In 1969‚ Seiko introduced the Astron‚ the world’s first production quartz watch when it was produced; it cost the same as a medium-sized car. In 1985‚ Orient Watches and Seiko established a joint factory. The company was incorporated (K.Hattori & Co.Ltd.)in 1917 and was renamed Hattori Seiko Co. Ltd in 1983 and Seiko

APPLICATION OF CHEMICAL SENSORS IN MECHANICAL ENGINEERING A chemical sensor is a device that transforms chemical information‚ ranging from the concentration of a specific sample component to total composition analysis‚ into an analytically useful signal. The chemical information‚ mentioned above‚ may originate from a chemical reaction of the analyte or from a physical property of the system investigated. Chemical sensors its application in various fields of engineering like civil‚ environment‚ medical

Mpenjati estuary‚ KZN. ABSTRACT The study was done in the Mpenjati estuary. It was found more briefly if sediment grain size and mineralogy distribution change across a beach profile changes and how it change. 4 zoneS of a beach profile were sampled. Quartz is the most stable sediment composition in the surface of the earth‚ compared to heavy minerals and feldspar (Marshak‚ 2008). INTRODUCTION The aim of the study was to find out how does the sediment grain size and mineralogy distribution change

Hornfels DEFINITION Hornfels is a very fine-grained metamorphosed shale rock‚ usually gray to black in color. Mineral composition in variable but is usually made up of some combination of equidimensional mosaic of quartz or calcite along with inequidimensional sheet silicates in random orientation or sometimes containing andalusite porphyroblasts. OCCURANCE Hornfels forms when shale rocks come into contact with a hot igneous intrusion body at lower pressures and at the equilibrium temperature

across India. Titan watches are sold in India through exclusive Titan showrooms called “The World of Titan” and through various franchisees and through retail stores. The company brought about a paradigm shift in the Indian watch market‚ offering quartz technology with international styling‚ manufactured in a state-of-the-art factory at Hosur in Tamil Nadu. Leveraging its understanding of different segments in the watch market‚ the company launched a second independent watch brand‚ Sonata as a value

remember them as. Some headstones can become very expensive depending on what kind of stone you get and what you put on it. The most common rocks used to make headstones are granite‚ marble‚ and sandstone. Granite is an “igneous rock made of mostly quartz and feldspar with some mica‚ and amphiboles” (Granite‚ 2017). Granite has a granular texture. Granite forms from magma slowly crystalizing below the surface of the Earth. The magma then cools down before reaching the Earth’s surface and forms large
