Drag Suit
Competitive swimwear refers to the swimsuit, clothing, equipment, and accessories used in the aquatic sports of swimming, diving, synchronized swimming, triathlon, and water polo. Some swimsuits are designed specifically for swimming competitions where they may be constructed of a special low resistance fabric that reduces skin drag. For some kinds of swimming and diving, special bodysuits called "diveskins" are worn. These suits are made from spandex and provide little thermal protection, but they do protect the skin from stings and abrasion. Most competitive swimmers also wear special swimsuits including partial bodysuits, racerback styles, jammers and racing briefs to assist their glide through the water thus gaining a speed advantage. Unlike regular swimsuits, which are designed mainly for aesthetic appearances, swimsuits designed to be worn during competitions are manufactured to assist the athlete in swim competitions. They reduce friction and drag in the water, incre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FINA World Championships
The FINA World Championships or World Aquatics Championships are the World Championships for aquatics sports: swimming, diving, high diving, open water swimming, artistic swimming, and water polo. They are run by FINA, and all swimming events are contested in a long course (50-metre) pool. The event was first held in 1973 in Belgrade, Yugoslavia, and is now held every two years. From 1978 to 1998, the World Championships were held every four years, in the even years between Summer Olympic years. From 2001 until 2019, the Championships have been held every two years, in the odd years. Due to the effects of the Covid-19 pandemic, the scheduling of both the Olympic Games and the Championships between 2019 and 2025 became somewhat erratic, with World Championships not taking place in Japan in 2021 to accommodate the delayed 2020 Summer Olympics, and then delayed again to 2023 because of pandemic-related issues in Japan. As a result, an extraordinary edition of the event was announc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Drag (physics)
In fluid dynamics, drag (sometimes called air resistance, a type of friction, or fluid resistance, another type of friction or fluid friction) is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid. This can exist between two fluid layers (or surfaces) or between a fluid and a solid surface. Unlike other resistive forces, such as dry friction, which are nearly independent of velocity, the drag force depends on velocity. Drag force is proportional to the velocity for low-speed flow and the squared velocity for high speed flow, where the distinction between low and high speed is measured by the Reynolds number. Even though the ultimate cause of drag is viscous friction, turbulent drag is independent of viscosity. Drag forces always tend to decrease fluid velocity relative to the solid object in the fluid's path. Examples Examples of drag include the component of the net aerodynamic or hydrodynamic force acting opposite to the di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lycra
Spandex, Lycra, or elastane is a synthetic fiber known for its exceptional elasticity. It is a polyether-polyurea copolymer that was invented in 1958 by chemist Joseph Shivers at DuPont's Benger Laboratory in Waynesboro, Virginia, US. The generic name "spandex", which is an anagram of the word "expands", is the preferred name in North America. In continental Europe, it is referred to by variants of "elastane", including (France), (Germany, Sweden), (Spain), (Italy), and (Netherlands); and in the UK, Ireland, Portugal, Spain, Latin America, Australia, and New Zealand, it is primarily known as "Lycra". Brand names for spandex include Lycra (made by The Lycra Company, previously a division of DuPont Textiles and Interiors), Elaspan (The Lycra Company), Acepora (Taekwang Group), Creora (Hyosung), INVIYA (Indorama Corporation), ROICA and Dorlastan (Asahi Kasei), Linel (Fillattice), and ESPA (Toyobo).

Bereavement in Judaism () is a combination of ''minhag'' and ''mitzvah'' derived from the Torah and Judaism's classical rabbinic texts. The details of observance and practice vary according to each Jewish community. Mourners In Judaism, the principal mourners are the first-degree relatives: parent, child, sibling, and spouse. There are some customs that are unique to an individual mourning a parent. Halachot concerning mourning do not apply to those under thirteen years of age, nor do they apply when the deceased is aged 30 days or less. Upon receiving news of the death Upon receiving the news of the death, the following blessing is recited: : :Transliteration: :Translation: "Blessed are You, Lord, our God, King of the universe, the Judge of Truth lt., the Just Judge" There is also a custom of rending one's clothes at the moment one hears news of a death. Another prevalent custom is to tear at the funeral.Klein, Isaac, A Guide to Jewish Religious Practice, Ktav Publishing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Navel
The navel (clinically known as the umbilicus, commonly known as the belly button or tummy button) is a protruding, flat, or hollowed area on the abdomen at the attachment site of the umbilical cord. All placental mammals have a navel, although it is generally more conspicuous in humans. Structure The umbilicus is used to visually separate the abdomen into quadrants. The umbilicus is a prominent scar on the abdomen, with its position being relatively consistent among humans. The skin around the waist at the level of the umbilicus is supplied by the tenth thoracic spinal nerve (T10 dermatome). The umbilicus itself typically lies at a vertical level corresponding to the junction between the L3 and L4 vertebrae, with a normal variation among people between the L3 and L5 vertebrae. Parts of the adult navel include the "umbilical cord remnant" or "umbilical tip", which is the often protruding scar left by the detachment of the umbilical cord. This is located in the center of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

2008 Summer Olympics
The 2008 Summer Olympics (), officially the Games of the XXIX Olympiad () and also known as Beijing 2008 (), were an international multisport event held from 8 to 24 August 2008, in Beijing, China. A total of 10,942 athletes from 204 National Olympic Committees (NOCs) competed in 28 sports and 302 events, one event more than those scheduled for the 2004 Summer Olympics. This was the first time China had hosted the Olympic Games, and the third time the Summer Olympic Games had been held in East Asia, following the 1964 Olympics in Tokyo, Japan, and the 1988 Olympics in Seoul, South Korea. These were also the second Summer Olympic Games to be held in a communist state, the first being the 1980 Summer Olympics in the Soviet Union (with venues in Russia, Ukraine, Belarus, and Estonia). Beijing was awarded the 2008 Games over four competitors on 13 July 2001, having won a majority of votes from members of the International Olympic Committee (IOC) after two rounds o ...

LZR Racer
The LZR Racer (pronounced as "laser") is a line of competition swimsuits manufactured by Speedo using a high-technology swimwear fabric composed of woven elastane-nylon and polyurethane. The swimsuits are made in body-length; they compress the body and trap air for buoyancy. The LZR Pro and LZR Elite were launched on 13 February 2008; the higher-priced LZR Elite was replaced by the LZR Elite 2 in early 2014. The LZR X, the most recent addition to Speedo's competition suit lineup, was launched in early 2015. The technology is patented in Italy, and protected worldwide. The swimsuits have been found to improve performance, and permitting their use in competitive swimming has been controversial, and led to changes in regulations. People have gone so far as to label their use as "technical doping". They were deemed to provide an unfair advantage to the wearer by FINA, which led to a ban on all swimsuits of a similar nature. Design and development The LZR Pro and LZR Elite were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
