Racquetball is a racquet sport played with a hollow rubber ball on an indoor or outdoor court. Joseph Sobek is credited with inventing the modern sport of racquetball in 1950, adding a stringed racquet to paddleball in order to increase velocity and control. Unlike most racquet sports, such as tennis and badminton, there is no net to hit the ball over, unlike squash, no tin to hit the ball above; the court's walls and ceiling are legal playing surfaces, with the exception of court-specific designated hinders being out-of-bounds. Racquetball is similar to 40×20 American handball, played in many countries, it is very similar to the British sport Squash 57, called racketball before 2016. Joe Sobek is credited with inventing the sport of racquetball in the Greenwich, Connecticut, YMCA, though not with naming it. A professional tennis and American handball player, Sobek sought a fast-paced sport, easy to learn and play, he designed the first strung paddle, devised a set of rules, based on those of squash and paddleball, named his game paddle rackets.

In February 1952 Sobek founded the National Paddle Rackets Association, codified the rules, had them printed as a booklet. The new sport was adopted and became popular through Sobek's continual promotion of it. In 1969, aided by Robert W. Kendler, the president-founder of the U. S. Handball Association, the International Racquetball Association was founded using the name coined by Bob McInerney, a professional tennis player; that same year, the IRA assumed the national championship from the NPRA. In 1973, after a dispute with the IRA board of directors, Kendler formed two other racquetball organizations, yet the IRA remains the sport's dominant organization, recognized by the United States Olympic Committee as the American national racquetball governing body. In 1974, the IRA organized the first professional tournament, is a founding member of the International Racquetball Federation; the IRA became the American Amateur Racquetball Association. In 2003, the USRA again renamed itself to USA Racquetball, to mirror other Olympic sports associations though Racquetball is ‘’not’’ an Olympic sport.

Kendler used his publication ACE to promote both racquetball. Starting in the 1970s, aided by the fitness boom of that decade, the sport's popularity increased to an estimated 3.1 million players by 1974. Consequent to increased demand, racquetball clubs and courts were founded and built, sporting goods manufacturers began producing racquetball-specific equipment; this growth continued until the early 1980s, declining in the decade's latter part when racquet clubs converted to physical fitness clubs, in service to a wider clientele, adding aerobics exercise classes and physical fitness and bodybuilding machines. Since the number of players has remained steady, an estimated 5.6 million. In 1976, Ian D. W. Wright created the sport of racketball based on U. S. racquetball. British racketball is played in a 32-foot long by 21-foot wide squash court –8 feet shorter and 1 foot wider than the U. S. racquetball court–, using a smaller, less dynamic ball than the American racquetball. In racketball, the ceiling is out-of-bounds.

The racketball is served after a bounce on the floor struck into play with the racket. Scoring is like squash with point-a-rally scoring of up to 11 points; the British Racketball Association was formed on 13 February 1984, confirmed by the English Sports Council as the sport's governing body on 30 October 1984. The first National Racketball Championship was held in London on 1 December 1984; the sport is now played in countries where squash is played, Bermuda, Germany, the Netherlands, New Zealand, South Africa, Argentina and Sweden. Racketball is played in parts of North America. In 1988, the British Racketball Association merged with the Squash Rackets Association. England Squash & Racketball is now recognised by Sport England as the English national governing body for the sports of squash and racketball. There is now an established UK Racketball Tournament Series consisting of 8 events around the UK, which forms the basis of the national rankings along with the National Racketball championships held annually at The Edgbaston Priory Club.

In 2016, World Squash Federation announced an international're-branding' of racketball as Squash 57, the 57 referring to the diameter of the ball, in order to emphasise both its membership of the'squash rackets' family, its distinctiveness from the U. S. racquetball The International Racquetball Federation governs the World Racquetball Championships, which were first held in 1981 in conjunction with the first World Games. The second World Championships were played in 1984, since have been held biennially in August. Players from the United States have won the most World Championship titles; the IRF runs the World Junior Racquetball Championships that occur annually in either late October, or early to mid November, as well as the annual World Senior Racquetball Championships for players who are 35 years of age or older. Racquetball has been included in the World Games on five occasions: 1981, 1989, 1993, 2009 and 2013; the sport has a high appeal in the Americas, because of this racquetball has been included in the Pan American Games in 1995, 1999, 2003, 2011 and 2015.

Bali Strait

Bali Strait is a stretch of water separating Java and Bali while connecting the Indian Ocean and the Bali Sea. At its narrowest it is 2.4 kilometres wide. The Bali Strait is one of the bodies of water surrounding the island of Bali: Lombok Strait to the east, the Badung Strait to the southeast, the Bali Sea to the north, the Indian Ocean to the southwest, the Bali Strait to the west. Geologically the two islands of Bali and Java were joined until the end of the last Ice Age when the sea rose and cut the land bridge, they both share. The Indonesian government has considered a bridge across the strait; the project is obstructed by economic hardships, as well as objections from certain locals in Bali. There is no fixed link to Bali, only a ferry between Ketapang in Java and Gilimanuk, Jembrana Regency, Bali. On 28 January 1797 during the Bali Strait Incident a French squadron of six frigates encountered fleet of six British East Indiaman in the Bali Strait. Disguising themselves as ships of the line, the British merchant ships were able to intimidate the French into withdrawing.

The temperature of the water in Bali Strait is subject to noticeable seasonal fluctuations, predetermined by the periods of monsoons. During the period of the northwestern monsoon, average temperature is about 28-29 °C, whereas in the southeast temperature drops to 26 °C. Regardless of the season, the water temperature in the northern part of the strait is 1-1.5 degrees lower than it is in the southern part. The level of salinity is more stable: about 33 ‰ in the season of the northwestern monsoons and about 34 ‰ in the southeast period. Sea currents in the strait have a complex configuration dependent on monsoon seasons: during the northwesterly winds, the northern vector predominates, while in the south-east it is the southern one; the maximum speed - up to 13 km / h - flows reach the northern, most narrow part of the strait. Tidal currents have a semi-diurnal amplitude. At the beginning of the 21st century, there were noticeable negative trends in the development of the ecological situation in the strait and on its shores, related to human economic activity.

Numerous cases of water pollution with industrial wastes, fertilizers, as well as chemicals used in gold mining on the Javanese shore are recorded

Mouse brain development timeline

The house mouse has a gestation period of 19 to 21 days. Key events in mouse brain development occur both before and after birth, beginning with peak neurogenesis of the cranial motor nuclei 9 days after conception, up to eye opening which occurs after birth and about 30 days after conception.

Duchy of Masovia

The Duchy of Masovia was a medieval duchy formed when the Polish Kingdom of the Piasts fragmented in 1138. It was located in the historic Masovian region of northeastern Kingdom of Poland; the duchy was re-incorporated into the Jagiellonian Kingdom of Poland by 1526. The Duchy went through various border changes in the coming years, sometimes losing and sometimes gaining territory; the lands of the Masovians east of the Vistula river had been conquered by the Piast duke Mieszko I of Poland and formed a constituent part of his Civitas Schinesghe. The Masovian Diocese of Płock was established in 1075. Following the death of Duke Bolesław III Wrymouth in 1138, as specified by his testament, the Masovian province was governed by his second son Bolesław IV the Curly, after he had expelled his elder half-brother Władysław II, in 1146 became Grand Prince of Poland, his Masovian realm comprised the adjacent lands of Kujawy on the west bank of the Vistula. Among the Piast Dukes of Masovia, Bolesław's IV nephew Konrad I was Polish high duke from 1229 to 1232 and again from 1241 to 1243.

In turn he ceded the Prussian Chełmno Land to the knights in 1230. In 1233 Konrad gave Kujawy to his second son Casimir I, while Masovia passed to the first-born Bolesław I upon his death in 1247, succeeded by the youngest brother Siemowit I the next year. While Siemowit's son Duke Konrad II moved his residence to Czersk he and his brother Bolesław II entered into a long-term conflict over the Polish seniorate with their Kujawy relatives and the Silesian Piasts, which estranged them from the Piast monarchy; when the kingdom was restored in 1295 by the coronation of Duke Przemysł II of Greater Poland, the Duchy of Masovia remained independent. Upon the death of Duke Boleslaus II in 1313, Masovia was divided among his sons: Siemowit II became Duke at Rawa Trojden I became Duke at Czersk Wenceslaus became Duke at Płock, followed by his son Bolesław III As neither Siemowit II nor Bolesław III of Płock left any heirs, Trojden's son Duke Siemowit III was able to re-unite most of the Masovian lands under his rule.

Upon Siemowit's III death in 1381 however, Masovia was again partitioned between his sons: Janusz I, ruled as duke at Czersk until 1413, when he moved his residence to Warsaw, followed by his grandson Duke Boleslaus IV Siemowit IV, Duke at Rawa and Płock Duke of Belz from 1388Since the Polish-Lithuanian Union of 1385, Masovia was localized between the joined Jagiellonian states. The Dukes of Masovia ruled the Duchy of Belz until 1462. After the establishment of the Rawa and Płock Voivodeships, in 1495 the last surviving son of Boleslaus IV, Duke Konrad III Rudy, once again united the remaining Masovian lands under his rule. However, the male line of the Masovian Piasts became extinct upon the death of his son Duke Janusz III in 1526, whereafter the duchy as a reverted fief became the Masovian Voivodeship of the Polish Crown. Parts of the southern region of neighboring East Prussia received settlers and Protestant religious refugees who became known as the Mazurs. By the 18th century the portion of East Prussia in which they settled was sometimes referred to as Masuria, inhabited by a Protestant population of Germans and Poles.
