Artà
Coordinates: 39°42′N 3°21′E / 39.700°N 3.350°E / 39.700; 3.350
Artà is one of the 53 independent municipalities on the Spanish Balearic island of Majorca. The small town of the same name is the administrative seat of this municipality in the region (Comarca) of Llevant.
Population
In 2008 the municipality of Artà had a population of 7,113 recorded residents within an area of 139.63 square kilometres (53.91 sq mi). This equates to 50.9 inhabitants per km2. In 2006 the percentage of foreigners was 13.2% (890), of which Germans made up 3.9% (262). In 1991 there were still 136 illiterates in the municipality. 1,292 inhabitants had no education, 1,675 only a primary school certificate and 1,210 had secondary school leaving certificates. The official languages are Catalan and Spanish (Castilian). The Catalan dialect spoken on the island is known as Mallorquí.
Geography
Location
Artà lies in the northeast of the island of Majorca, around 60 km from the island's capital of Palma. The Massís d’Artà, the highest and most compact massif in the eastern mountain chain of the Serres de Llevant, occupies more than half the area of the municipality. The municipality is located on the western part of peninsula of Artà and is bordered in the west by the Bay of Alcúdia (Badia d’Alcúdia), and in the north by the Mediterranean sea where its coast lies opposite the neighbouring island of Minorca. The coast of Artà stretches for 25 kilometres and, so far, has escaped being developed. Particularly noteworthy are the beach and sand dune formations of sa Canova d’Artà, the flat coastal strip near the settlement of Colònia de Sant Pere, the high rocky coves of the Cap de Ferrutx and a large number of smaller bays that extend from s’Arenalet des Verger to Cala Torta.
ART image file format
ART is a proprietary image file format used mostly by the America Online (AOL) service and client software.
Technical details
The ART format (file extension ".art") holds a single still image that has been highly compressed. The format was designed to facilitate the quick downloading of images, among other things. Originally, the compression was developed by the Johnson-Grace Company, which was then acquired by AOL. When an image is converted to the ART format, the image is analyzed and the software decides what compression technique would be best. The ART format has similarities to the progressive JPEG format, and certain attributes of the ART format can lead to image quality being sacrificed for the sake of image compression (for instance, the image's color palette can be limited.)
Usage by AOL
The AOL service used the ART image format for most of the image presentation of the online service. In addition, the AOL client's web browser also automatically served such images in the ART format to achieve faster downloads on the slower dialup connections that were prevalent in those days. This conversion was done in the AOL proxy servers and could be optionally disabled by the user. This image conversion process effectively reduced the download time for image files. This technology was once branded as Turboweb and is now known as AOL TopSpeed.
Momentum (electromagnetic simulator)
Momentum is 3-D planar EM simulation software for electronics and antenna analysis, a partial differential equation solver of Maxwell's equations based on the method of moments. It is a 3-D planar electromagnetic (EM) simulator used for passive circuit analysis.
It combines full-wave and quasi-static EM solvers to provide insight into EM behavior of MMIC, RFIC, RF Board, Signal Integrity, and antenna designs. The Momentum simulation engine is integrated into Keysight ADS and Keysight Genesys.
It was originally developed by a Belgian company, Alphabit, a spinoff from IMEC. Early contributors to the technology include Niels Faché, Jan Van Hese, Frank Libbrecht, Jeannick Sercu, Luc Vandormael, Mieke Herreman, Peter Kok, Tom Dhaene and Krist Blomme.
The company was acquired by Hewlett-Packard, later it became part of Agilent Technologies and since November 2014 it is part of Keysight Technologies EEsof division, the current owners.

Spectator sport
A spectator sport is a sport that is characterized by the presence of spectators, or watchers, at its matches. For instance, American football, association football, baseball, basketball, professional boxing, Canadian football, cricket, field hockey, Formula One, ice hockey, rugby league, rugby union, soccer, team handball, tennis and volleyball are spectator sports, while hunting or underwater hockey typically are not. Spectator sports may be professional sports or amateur sports. They often are distinguished from participant sports, which are more recreational; golf and tennis can be either. Association football, also known as soccer, is by far the most watched sport on the planet.
The increasing broadcasting of sports events, along with media reporting can affect the number of people attending sports due to the ability to experience the sport without the need to physically attend and sometimes an increasingly enhanced experience including highlights, replays, commentary, statistics and analysis. Some sports are particularly known as "armchair sports" or "lounge room sports" due to the quality of the broadcasting experience in comparison to the live experience.
Four-momentum
In special relativity, four-momentum is the generalization of the classical three-dimensional momentum to four-dimensional spacetime. Momentum is a vector in three dimensions; similarly four-momentum is a four-vector in spacetime. The contravariant four-momentum of a particle with energy E and three-momentum p = (px, py, pz) = mu = γmv, where v is the particles 3-velocity and γ the Lorentz factor, is
The quantity mv of above is ordinary non-relativistic momentum of the particle and m its rest mass. The four-momentum is useful in relativistic calculations because it is a Lorentz vector. This means that it is easy to keep track of how it transforms under Lorentz transformations.
The above definition applies under the coordinate convention that x0 = ct. Some authors use the convention x0 = t, which yields a modified definition with p0 = E/c2. It is also possible to define covariant four-momentum pμ where the sign of the energy is reversed.
Minkowski norm
Calculating the Minkowski norm of the four-momentum gives a Lorentz invariant quantity equal (up to factors of the speed of light c) to the square of the particle's proper mass:
Choke (horse)
Choke is a condition in horses in which the esophagus is blocked, usually by food material. Although the horse is still able to breathe, it is unable to swallow, and may become severely dehydrated. A secondary condition, aspiration pneumonia, may also develop if food material and saliva accumulate in the pharynx, spilling into the trachea and into the lungs. Choke is one of the "top 10" emergencies received by equine veterinarians.
The condition is seen in other Equidae like mules and donkeys.
Causes
Chewing: Horses may develop choke if they do not chew their food properly. Therefore, horses with dental problems (e.g. acquired or congenital malocclusion, loose or missing teeth, or excessively sharp dental ridges) that do not allow them to completely grind their food are particularly at risk. In addition, horses that bolt their feed and do not take the time to chew properly are more likely to suffer from choke.
Dry Food: Dry foods may cause choke, especially if the horse does not have free access to water, or if the horse has other risk factors linked to choking. While pelleted or cubed feeds in general fall in this category, horse owners sometimes express particular concerns about beet pulp. However, while horses have choked on beet pulp, a university study did not document that beet pulp is a particular problem. It is believed that choke related to beet pulp is linked to the particle size and the horse's aggressive feeding behaviour, rather than the actual feed itself. Research suggests that horses that bolt their feed without sufficient chewing, or who do not have adequate access to water, are far more likely to choke, regardless of the type of feed, compared to horses that eat at a more leisurely rate. The risk of choke associated with any dry feed can be reduced by soaking the ration prior to feeding.
