Franz Reuleaux, was a mechanical engineer and a lecturer of the Berlin Royal Technical Academy appointed as the President of the Academy. He was called the father of kinematics, he was a leader in his profession, contributing to many important domains of knowledge. Today, he may be best remembered for the Reuleaux triangle, a curve of constant width that he helped develop as a useful mechanical form. Reuleaux was born in Eschweiler in Germany, his father and grandfather were both machine builders. His technical training was at the Karlsruhe Polytechnic School, he studied at universities in Berlin and Bonn. After a time spent in the family business he became a professor at the Swiss Federal Institute in Zurich. In 1879 he became Rector at the Königs Technischen Hochschule Berlin – Charlottenburg; this was a major technical institute, with about 300 professors. He became known as an engineer-scientist — a professor and industrial consultant, education reformer and leader of the technical elite of Germany.
Reuleaux was the appointed chairman of the German panel of judges for the Sixth World Industrial Fair opened in Philadelphia on 10 May 1876. He admitted that German-made goods were far inferior to those of other countries and that German industry's guiding principle was “billig und schlecht”; this evoked wide comment in the press. Reuleaux was a consultant to the development of the Otto-Langen internal combustion engine, winner of the 1867 World's Fair in Paris, based on efficiency. Reuleaux served on several international juries and commissions and involved in formation of a patent system, as he was active in German politics, he was a member of the Royal Swedish Academy of Sciences from 1882. Reuleaux believed that machines could be abstracted into chains of elementary links called kinematic pairs. Constraints on the machine are described by constraints on each kinematic pair, the sequence of movements of pairs produces a kinematic chain, he developed a compact symbolic notation to describe the topology of a wide variety of mechanisms, showed how it could be used to classify them and lead to the invention of new useful mechanisms.
At the expense of the German government, he directed the design and manufacture of over 300 beautiful models of simple mechanisms, such as the four-bar linkage and the crank. These were sold to universities for pedagogical purposes. Today, the most complete set are at Cornell University College of Engineering. Using his notation and methods for systematically varying the elements he showed how the four-bar linkage could be mutated into 54 mechanisms, which fall within 12 classes.

Yacht is a public domain dice game, similar to the Latin American game Generala, the English game of Poker Dice, the Scandinavian Yatzy, Cheerio. Yacht dates back to at least 1938, is a contemporary of the similar three-dice game Crag. Yahtzee is a development, similar to Yacht in both name and content; the name Yacht is used for a number of dice games that include many features of Yahtzee, being closer to Yahtzee than the original Yacht game. The object of the game is to score points by rolling five dice to make certain combinations; the dice can be rolled up to three times in a turn to try to make these combinations. A game consists of twelve rounds. After each round the player chooses. Once a category has been used in the game, it cannot be used again; the scoring categories have varying point values, some of which are fixed values and others where the score depends on the value of the dice. A Yacht is scores 50 points; the winner is the player. The following are the 12 categories and the points scored in those categories: If a category is chosen but the dice do not match the requirements of the category the player scores 0 in that category.
A Yacht cannot be scored on Full House but can be scored on Four of a Kind, although the fifth die is not counted in the score. The scores for the Straights vary; the maximum possible score depends on the scoring rules used, but with the above rules and both straights counting 30, the maximum score is 297. The rules of Yacht differ from those of Yahtzee in a number of ways: It does not have an upper section bonus. There is no three-of-a-kind category. Both straights are set sequences of five. There are no Yahtzee bonuses or Joker rule. There are a number of differences to the category names compared to Yahtzee. "Aces" is called "Ones", "Large Straight" is called "Big Straight", "Yahtzee" is called "Yacht" and "Chance" is called "Choice". The order of the categories on the score sheet can be different from that used on a Yahtzee score sheet. There is no "upper" or "lower" section scoring, just a "Total" row at the bottom of the score sheet. Although there are no official rules for Yacht, the scoring of some categories differs from that used in Yahtzee.
Four-of-a-kind scores the sum of those four dice, not all five dice. Full house scores the sum of the five dice, not a fixed score of 25; the scores for the straights can be different from those used in Yahtzee Game design
Olindiidae is a family of hydrozoans in the order Limnomedusae. They have a medusa phase; the polyps are small and solitary, but a few species are colonial. They can reproduce by budding. In the largest species, the medusae can grow to 15 cm. Centripetal canals may be present or absent and the radial canals are unbranched; the gonads are except in Limnocnida, where they are on the manubrium. The fertilised eggs develop into planula larvae; these can bud off medusae. In some species, medusae are only produced. Most species are marine, but several can be found in brackish water and a few, notably Craspedacusta and Limnocnida, are found in fresh water; this family is named after its type genus Olindias Muller 1861, but with confusion about the correct spelling, with Olindiadae, Olindiidae and Olindiasidae all being used. Haeckel established the family in 1879 as Olindiadae, but his intentions as to the stem of the genus and hence the name of the family are unclear. In 2010, Calder determined; the World Register of Marine Species lists these genera: Aglauropsis Mueller, 1865 Astrohydra Hashimoto, 1981 Calpasoma Fuhrmann, 1939 Craspedacusta Lankester, 1880 Cubaia Mayer, 1894 Eperetmus Bigelow, 1915 Gonionemus A.

"Hō-Ren-Sō" is a business mantra or mnemonic acronym in Japanese business culture. It is an "abbreviation of "Hōkoku", "Renraku" and "Sōdan", is more memorable as a homonym of hōrensō, the Japanese word for "spinach", it is utilized as a basic business rule in Japan to conduct smooth business communication. The origin of "Ho-Ren-So" comes from Tomiji Yamazaki, the ex-president of Yamatana Security firm. In 1982 he started using the term for effective business communication in his firm and it has been spread and used throughout Japan through his book, "Strengthen your company with Ho-Ren-So". "Hokoku" is to report on a result of business from a subordinate to a superior. In Japan, subordinates don't have much authority to make business decision; the decisions are made by an organization as a whole. Therefore, a subordinate must report everything to superior and exactly, it is important to report a mistake or a problem because his/her superior has the responsibility for it. "Renraku" is to inform facts.
One must inform the facts and decision to the relevant parties. One should not include one's opinion and guesses. If "Renraku" is not done or not completed you cannot control your team, and "Renraku" communicated to the people who need it. "Renraku" done quickly. Its content might need to prepare for the next action. "Sodan" is to discuss. For example, a superior give a subordinate an advice, an employee talks over with superior about some unnecessary consultation in Japanese business; because a superior speaks to a subordinate in the Japanese company, they want to be asked for their advice. They want others to think that "you can always count on me." So, they feel better. There are many benefits to incorporating the "Ho-Ren-So" philosophy. First, if an issue within tasks are reported, it can be resolved because a manager controls it and decides how to resolve it. Next, if information is communicated with team members and it is known all members of a team, they can take ownership of the schedule and tasks.
If information is consulted from a subordinate, a decrease of quality will be prevented and won't occur again. On the other hand, there are some Cons in "Ho-Ren-So". First, there is a cost of management, it is a time-consuming process, leaving employees with little time to complete their various work assignments. Moreover, since a subordinate must always wait instructions from his/her supervisor, this prevents employees from applying problem-solving skills on their own without the constant need for managerial input
Jakub Brabec is a Czech professional footballer who plays as a centre/right back for Czech club Viktoria Plzeň. Jakub was part of the youth system at Sparta Prague, but having been released in the summer of 2008 he joined Viktoria Žižkov, another Prague-based club, he was promoted to the Žižkov first team during the 2008–09 Gambrinus liga season, when he was still at school. He made one league appearance for the club in this season, playing a full match against FC Viktoria Plzen as a 16-year-old in a 2–0 defeat. In the 2009–10 season, he played a further 14 games for Žižkov, who were playing in the second tier Czech 2. Liga. One of the fourteen appearances was as a substitute. In one match in this season, against FC Zenit Čáslav, he received a 31st-minute red card, he made six appearances in the Czech 2. Liga in the following 2010–11 season, four of which were as a substitute, he helped Žižkov achieve a second-place league promotion back to the Gambrinus liga. In June 2011, he secured a move back to Sparta Prague, for an undisclosed fee.
He told Uefa.com that his primary motivation for making the transfer was that he was a childhood fan of his former club and that he would have a better chance of playing in the Uefa Cup and the Uefa Champions League. He started the 2011–12 season with the reserve team, Sparta Prague II, who compete in the 2. Liga. On August 31, Jakub signed a 4 year deal with K. R. C. Genk, where he will be playing as a centre back/right back. Jakub has represented the Czech Republic at youth international level, he scored his first national goal on his third and final appearance for the Czech Republic under-18s in a 3–1 loss to the Austria under-18s in a March 2010 friendly match. In 2009, he made his debut for the Czech Republic under-19s in a 4–0 win over the Malta under-19s, he was selected as captain of the Czech Republic under-19s squad for the 2011 UEFA European Under-19 Championship. His first goal at under-19 level came in this tournament, he scored a header in a group game tournament fixture against the Republic of Ireland under-19s to equalise 1–1 on 23 July 2011.
