Engineering

Engineering is the application of mathematics, empirical evidence and scientific, economic, social, and practical knowledge in order to invent, innovate, design, build, maintain, research, and improve structures, machines, tools, systems, components, materials, and processes.

The discipline of engineering is extremely broad, and encompasses a range of more specialized fields of engineering, each with a more specific emphasis on particular areas of applied science, technology and types of application.

The term Engineering is derived from the Latin ingenium, meaning "cleverness" and ingeniare, meaning "to contrive, devise".

Definition

The American Engineers' Council for Professional Development (ECPD, the predecessor of ABET) has defined "engineering" as:

History

Engineering has existed since ancient times as humans devised fundamental inventions such as the wedge, lever, wheel, and pulley. Each of these inventions is essentially consistent with the modern definition of engineering.

Withania somnifera

Withania somnifera, known commonly as ashwagandha,Indian ginseng,poison gooseberry, or winter cherry, is a plant in the Solanaceae or nightshade family. Several other species in the genus Withania are morphologically similar. It is used as a herb in Ayurvedic medicine.

Description

This species is a short, tender perennial shrub growing 35–75 cm (14–30 in) tall. Tomentose branches extend radially from a central stem. Leaves are dull green, elliptic, usually up to 10 - 12 cm. long. The flowers are small, green and bell-shaped. The ripe fruit is orange-red.

Etymology

The species name somnifera means "sleep-inducing" in Latin.

Cultivation

Withania somnifera is cultivated in many of the drier regions of India, such as Mandsaur District of Madhya Pradesh, Punjab, Sindh, Gujarat, and Rajasthan. It is also found in Nepal, China and Yemen.

Pathology

Withania somnifera is prone to several pests and diseases. Leaf spot disease caused by Alternaria alternata is the most prevalent disease, which is most severe in the plains of Punjab, Haryana, and Himachal Pradesh. Biodeterioration of its pharmaceutically active components during leaf spot disease has been reported. The Choanephora cucurbitarum causes a stem and leaf rot of Withania somnifera A treehopper, feeds on the apical portions of the stem, making them rough and woody in appearance and brown in colour. The apical leaves are shed and the plant gradually dies. The carmine red spider mite (Tetranychus urticae) is the most prevalent pest of the plant in India.

Mountain Rose Herbs

Mountain Rose Herbs is an American herbal distribution retailer based in Eugene, Oregon and founded in 1987. It is the first Fair Trade Certified supplier of medicinal herbs in the United States.

Background

Herbalist Rosemary Gladstar started Mountain Rose Herbs in order to provide herbal materials and supplies to students of the California School of Herbal Studies. The retailer continued as a home-based business in Humboldt County, California until the late 1990s, under several different owners, filling orders by mail from a small catalog. In 1998 the company moved into a larger residential location in North San Juan, California.

Mountain Rose Herbs relocated to a commercial location in Pleasant Hill, Oregon in 2001 to be closer to many of its farms and suppliers. The retailer became a certified organic processor through Oregon Tilth in 2002. In 2010, the company moved again to a larger facility in Eugene, Oregon.

Education and events

In 2011, Mountain Rose Herbs created and hosted the four-day Rootstalk Festival in Salem, Oregon. Over 700 people attended herbal education workshops and classes taught by herbalists, botanists, and environmental experts. All proceeds went to the nonprofit known as Cascadia Wildlands.

Rapid transit

Rapid transit, also known as metro, subway or underground is a type of high-capacity public transport generally found in urban areas. Unlike buses or trams, rapid transit systems are electric railways that operate on an exclusive right-of-way, which cannot be accessed by pedestrians or other vehicles of any sort, and which is often grade separated in tunnels or on elevated railways.

Modern services on rapid transit systems are provided on designated lines between stations typically using electric multiple units on rail tracks, although some systems use guided rubber tyres, magnetic levitation, or monorail. The stations typically have high platforms, without steps inside the trains, requiring custom-made trains in order to avoid gaps. They are typically integrated with other public transport and often operated by the same public transport authorities. However, some rapid transit systems have at-grade intersections between a rapid transit line and a road or between two rapid transit lines. It is unchallenged in its ability to transport large numbers of people quickly over short distances with little use of land. Variations of rapid transit include people movers, small-scale light metro, and the commuter rail hybrid S-Bahn.
