High Quality Content by WIKIPEDIA articles! Seersucker is a thin, puckered, all-cotton fabric, commonly striped or checkered, used to make clothing for spring and summer wear. The word came into English from Hindustani (Urdu and Hindi), which originates from the Persian words "shir o shekar", meaning "milk and sugar", probably from the resemblance of its smooth and rough stripes to the smooth texture of milk and the bumpy texture of sugar. Seersucker is woven in such a way that some threads bunch together, giving the fabric a wrinkled appearance in places. This feature causes the fabric to be mostly held away from the skin when worn, facilitating heat dissipation and air circulation. It also means that pressing is not necessary.

In a polycrystalline solid, a segregation site can be a dislocation, grain boundary, stacking fault, or an interface with a precipitate or secondary phase within the solid. There are two recognized types of segregation: equilibrium segregation and non-equilibrium segregation.

Seismic retrofitting is the modification of existing structures to make them more resistant to seismic activity, ground motion, or soil failure due to earthquakes. With better understanding of seismic demand on structures and with our recent experiences with large earthquakes near urban centers, the need of seismic retrofitting is well acknowledged. Prior to the introduction of modern seismic codes in the late 1960s for developed countries (US, Japan etc.) and late 1970s for many other parts of the world (Turkey, China etc.), many structures were designed without adequate detailing and reinforcement for seismic protection. In view of the imminent problem, various research work has been carried...

Beyond conventional actuation, sensing and control typically found in fixed-morphology robots, self-reconfiguring robots are also able to deliberately change their own shape by rearranging the connectivity of their parts, in order to adapt to new circumstances, perform new tasks, or recover from damage.
High Quality Content by WIKIPEDIA articles! Self-healing materials are a class of smart materials that have the structurally incorporated ability to repair damage caused by mechanical usage over time. The inspiration comes from biological systems, which have the ability to heal after being wounded. Initiation of cracks and other types of damage on a microscopic level has been shown to change thermal, electrical, and acoustical properties, and eventually lead to whole scale failure of the material. Usually, cracks are mended by hand, which is difficult because cracks are often hard to detect. A material (polymers, ceramics, etc.) that can intrinsically correct damage caused by normal usage could lower production costs of a number of...
High Quality Content by WIKIPEDIA articles! Self-assembled monolayers (SAM) of organic molecules are molecular assemblies formed spontaneously on surfaces by adsorption and are organized into more or less large ordered domains. In some cases molecules that form the monolayer do not interact strongly with the substrate. This is the case for instance of the two dimensional supramolecular networks of e.g. Perylene-tetracarboxylicacid-dianhydride (PTCDA) on gold or of e.g. porphyrins on highly oriented pyrolitic graphite (HOPG). In other cases the molecules possess a functional group that has a strong affinity to the substrate and anchors the molecule to it. Such a SAM consisting of a head group, tail and functional end group is depicted in...

The Selgovae were a people of the late 2nd century who lived in what is now the Stewartry of Kirkcudbright and Dumfriesshire, on the southern coast of Scotland. They are mentioned briefly in Ptolemy`s Geography, and there is no other historical record of them. Their cultural and ethnic affinity is commonly assumed to have been Brittonic.

The site is served by Sellafield railway station. Sellafield is an off-shoot from the original nuclear reactor site at Windscale which is currently undergoing decommissioning and dismantling. Calder Hall, another neighbour of Windscale is also undergoing decommissioning and dismantling of its 4 nuclear power generating reactors.

Sembawang MRT Station (NS11) is an elevated Mass Rapid Transit (MRT) station in Singapore, and the northernmost MRT Station of the North South Line and part of the Woodlands Extension. It is sited in Sembawang, a residential area which is just over 6 years old and still undergoing development. The first level of the station is open in design and can be accessed from almost all sides. It is now integrated with the open-air, newly-opened Sembawang Bus Interchange which allows residents to commute to work or travel to other places easier. Sun Plaza Shopping Centre cum condominium is sited next to the station.

The Sensei X robotic catheter is a medical robot designed to enhance a physician’s ability to perform complex operations using a small flexible tube called a catheter. As open surgical procedures that require large incisions have given way to minimally invasive surgeries in which the surgeon gains access to the target organs through small incisions using specialized surgical tools. One important tool used in many of these procedures is a catheter used to deliver many of things a surgeon needs to do his work, to impact target tissue and deliver a variety of medicines or disinfecting agents to treat disease or infection.

Located at third level of VivoCity, the northern terminus is just a few levels above HarbourFront MRT Station and the nearby HarbourFront Bus Interchange. It is the only air-conditioned station, the only station on mainland Singapore and the only station with full-height platform screen doors on the line. Just like Changi Airport and Promenade MRT Stations, ticketing, turnstiles and platforms are all on the same level. Like the dismantled Sentosa Monorail stations in the past and Ten Mile Junction station, it is currently the only train station in Singapore to feature an organised boarding system like the Spanish...
High Quality Content by WIKIPEDIA articles! A separation barrier is a wall or fence constructed to limit the movement of people across a certain line or border, or to separate two populations. These structures vary in placement with regard to international borders and topography. The most famous example of a separation barrier is probably the Great Wall of China, a series of barriers separating the Empire of China from nomadic powers to the north; the most prominent recent example was the Berlin Wall that separated the enclave of West Berlin from the rest of East Germany during most of the Cold War era.

A septic tank is a key component of the septic system, a small-scale sewage treatment system common in areas with no connection to main sewage pipes provided by local governments or private corporations. (Other components, typically mandated and/or restricted by local governments, optionally include pumps, alarms, sand filters, and clarified liquid effluent disposal means such as a septic drain field, ponds, natural stone fiber filter plants or peat moss beds.) Septic systems are a type of On-Site Sewage Facility (OSSF). In North America, approximately 25% of the population relies on septic tanks; this can include suburbs and small towns as well as rural areas (Indianapolis is an example of a...

The station is located in the Serangoon Central area, at the intersection of Upper Serangoon Road and Serangoon Central. This station sees relatively heavy usage during peak periods, because a number of bus services which used to go to the city area now terminate at Serangoon Bus Interchange instead. The station is operated by SBS Transit on the North East Line and SMRT Corporation on the Circle Line.
