Spider

Spiders (order Araneae) are air-breathing arthropods that have eight legs and chelicerae with fangs that inject venom. They are the largest order of arachnids and rank seventh in total species diversity among all other orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every habitat with the exceptions of air and sea colonization. As of November 2015, at least 45,700 spider species, and 114 families have been recorded by taxonomists. However, there has been dissension within the scientific community as to how all these families should be classified, as evidenced by the over 20 different classifications that have been proposed since 1900.

Anatomically, spiders differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax and abdomen, and joined by a small, cylindrical pedicel. Unlike insects, spiders do not have antennae. In all except the most primitive group, the Mesothelae, spiders have the most centralized nervous systems of all arthropods, as all their ganglia are fused into one mass in the cephalothorax. Unlike most arthropods, spiders have no extensor muscles in their limbs and instead extend them by hydraulic pressure.

Kumo (sculpture)

Kumo is a public art work by artist Isaac Witkin located at the Lynden Sculpture Garden near Milwaukee, Wisconsin. The sculpture is an abstract form made of Corten steel curved shapes; it is installed on the lawn.

LEWA

LEWA is a manufacturer for diaphragm metering pumps, process pumps as well as customized metering systems and production units. The company has developed from a pure technology provider to a solution provider over the last years. LEWA systems are in use in oil & gas and chemical industry.

The headquarters of the company are located in Leonberg (Stuttgart Metropolitan Region) in the south of Germany. LEWA has 16 subsidiaries and over 80 sales partners on all continents.

LEWA-Nikkiso America, Inc., which has its head office in Holliston, Massachusetts, and LEWA Process Technologies, Inc., which has its office in Devens, Massachusetts, are American subsidiaries of the LEWA Group.

In 2013, LEWA generated a turnover of 218 million euro with more than 1,070 employees worldwide.

History

The company was founded in 1952 as "Ingenieurbüro LEWA" ("Engineering Office LEWA") by the two engineers Herbert Ott and Rudolf Schestag. LEWA stands for Leonberger Wasseraufbereitung (water conditioning in Leonberg). In 1954, LEWA applied for a patent for the rocker arm pump. In 1955, the company participated in Achema, an exhibition in Frankfurt am Main, for the first time.

Rock (geology)

In geology, rock or stone is a naturally occurring solid aggregate of one or more minerals or mineraloids. For example, the common rock granite is a combination of the quartz, feldspar and biotite minerals. The Earth's outer solid layer, the lithosphere, is made of rock.

Rocks have been used by mankind throughout history. From the Stone Age, rocks have been used for tools. The minerals and metals found in rocks have been essential to human civilization.

Three major groups of rocks are defined: igneous, sedimentary, and metamorphic. The scientific study of rocks is called petrology, which is an essential component of geology.

Classification

At a granular level, rocks are composed of grains of minerals, which, in turn, are homogeneous solids formed from a chemical compound that is arranged in an orderly manner. The aggregate minerals forming the rock are held together by chemical bonds. The types and abundance of minerals in a rock are determined by the manner in which the rock was formed. Many rocks contain silica (SiO₂); a compound of silicon and oxygen that forms 74.3% of the Earth's crust. This material forms crystals with other compounds in the rock. The proportion of silica in rocks and minerals is a major factor in determining their name and properties.
