Dance


Move is a kind of workmanship that for the most part includes development of the body, regularly cadenced and to music. It is performed in numerous societies as a manifestation of enthusiastic interpretation, social association, or activity, in a profound or execution setting, and is at times used to express thoughts or recount a story. Move might likewise be viewed as a manifestation of nonverbal correspondence between people or different creatures, as in honey bee moves and conduct examples, for example, a mating moves. Meanings of what constitutes move can rely on upon social and social standards and tasteful, aesthetic and good sensibilities. Definitions may run from practical development to virtuoso systems, for example, toe dance. Combative technique kata are regularly contrasted with moves, and games, for example, tumbling, figure skating and synchronized swimming are by and large thought to consolidate move.

There are numerous styles and classifications of move. African move is interpretative. Graceful dance, assembly hall and tango are established move styles. Square move and electric slide are manifestations of step move, and breakdancing is a kind of road move. Move could be participatory, social, or performed for a group of people. It can likewise be stately, aggressive or sensual. Move developments may be without essentialness in themselves, as in performance or European society move, or have a gestural vocabulary or typical importance as in some Asian moves. Choreography is the specialty of making moves. The individual who makes a move is known as the choreographer.

Tour d'Afrique

Tour d'Afrique is one of the longest bicycle races and expeditions in the world. It is organised by Tour d'Afrique Ltd. a Canadian company based in Toronto. It runs each year from January to May, from Cairo to Cape Town. Most of the participants are expedition riders who cover each day at their own pace, stopping in the villages and roadside cafes. The racing format is that of a stage race (~100 stages varying from 40 km to 200 km). There are about 20 rest days. The organisers prepare three meals every day and transport tents and other equipment the riders need for the night stops.

The 2003 Tour d'Afrique set a Guinness World Record for fastest crossing of Africa by bicycle and this was achieved by nine participants of the race, Michael Kennedy, Chris Evans, Dave Genders (all UK), Paul Reynaert (Belgium), Jeremy Wex, Steve Topsham, Scotty Robinson, Andrew Griffin (all Canada) and Sascha Hartl (Austria). The 2008 Tour d'Afrique did not cross Kenya due to the political situation and reported violence.

'White Stork' Delivers New Research and Technology Investigations to the International Space Station

A "white stork" is soon to deliver supplies to the International Space Station. But it's not the typical stork you associate with baby deliveries. The Japan Aerospace Exploration Agency's Kounotori3 H-II Transfer Vehicle, or HTV-3, is a 16.5-ton cargo ship. Kounotori is Japanese for "white stork."

Following a weeklong journey since its launch July 20, the HTV-3 is scheduled to dock to the station July 27 packed with nearly four tons of supplies, including a mix of NASA and international partner research ranging from biology to education to technology demonstration.

A Japan Aerospace Exploration Agency investigation will study new sampling techniques and environmental microbiological methods for environmental analysis. Microbial Dynamics in the International Space Station - III (Microbe-III) will monitor the abundance and diversity of fungi and bacteria in Kibo, the Japanese Experiment module on the station. The results will be used to produce a microbiologically safe environment which is essential for a long-duration stay in space.

Another Japanese investigation, In-situ Observation of Growth Mechanisms of Protein Crystals and Their Perfection Under Microgravity (NanoStep), aims to clarify the relationship between crystal growth mechanism and the perfection of crystals. Crystallization of proteins in microgravity yields crystals with better perfection than crystallization on Earth. This study will look at the reason for this phenomenon, which has not been explained from a viewpoint of crystal growth mechanism.

NASA's ISS SERVIR Environmental Research and Visualization System (ISERV) is an automated system designed to acquire images of the Earth's surface from the space station. It is primarily a means to gain experience and expertise in automated data acquisition from the station, although it is expected to provide useful images for use in disaster monitoring and assessment, and environmental decision making.

Five small mission payloads that perform science and technological demonstrations also are among the newest investigations arriving at the station. The Multi-mission Consolidated Equipment (MCE) includes two atmospheric observations that study lightning and resonant scattering from plasma and airglow. The other technology demonstrations include inflatable structure deployment, robotic tether movement and testing a high-definition television camera in the space environment.

Several educational activities are scheduled to begin after the supplies arrive at the station, including the Japan Aerospace Exploration Agency Education Payload Observation 5 (JAXA EPO5). These activities demonstrate artistic activities aboard the station to enlighten the public about microgravity research and human spaceflight.

Through an agreement with NASA, Space Adventures is sponsoring the YouTube Space Lab world-wide contest for students 14-to-18 years old. Over the past year, students submitted entries in the areas of physics or biology via a two-minute YouTube video. The top two experiments were selected in March 2012 through online voting and by an international panel of experts, including William Gerstenmaier, associate administrator for NASA's Human Exploration Mission Directorate, and Leland Melvin, NASA’s associate administrator for the Office of Education. The winning experiments -- from Egypt and Michigan -- are being flown to the station to be conducted later this year. One experiment will study how bacteria grow in space to see if different nutrients can block the growth. The other winning entry looks at how a Zebra spider -- which jumps on its prey instead of catching them in a web on Earth -- will hunt its prey in microgravity.

Several human research activities will arrive with the cargo ship, including Sonographic Astronaut Vertebral Examination (Spinal Ultrasound). This investigation aims to use ground- and space-based studies to fully characterize and assign a mission health risk to microgravity-associated spinal changes for back pain and potential injury. This research will determine the accuracy of the ultrasound in characterizing the anatomy and composition of the vertebral unit and help to develop new training methods.

In the area of physical sciences, the Binary Colloidal Alloy Test - C1 (BCAT-C1) experiment will study nano-scale particles dispersed in liquid, known as a colloidal suspension, commonly found in such commercial commodities as paint, electronic polishing compounds and food products. These suspensions will have the unique property that the particles will separate -- like oil and water -- and the particles will self-assemble into crystals that interact strongly with light, like opal. Photographing these samples in microgravity will allow the measurement of these processes while avoiding the effects of particle sinking due to gravity. This study will allow the development of new insights into this important materials process.

A technology demonstration, called The Reentry Breakup Recorder (REBR), tests a cost-effective system that rides a space vehicle reentering Earth’s atmosphere, records data during the reentry and breakup of the vehicle, and returns the data for analysis. Understanding how vehicles behave during atmospheric reentry gives future spacecraft developers unique information that can enhance design efficiencies and safety.

One of the new facilities for the station is the Aquatic Habitat. This habitat is capable of accommodating small fish, such as medaka or zebrafish, which have many advantages as vertebrate models. The Aquatic Habitat will be used for experiments investigating how microgravity and the space radiation environment affect living things including human beings, particularly over the long term.

Space


Space is the boundless, three-dimensional extent in which objects and events occur and have relative position and direction. Physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of the boundless four-dimensional continuum known as spacetime. In mathematics one examines 'spaces' with different numbers of dimensions and with different underlying structures. The concept of space is considered to be of fundamental importance to an understanding of the physical universe although disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework.

Debates concerning the nature, essence and the mode of existence of space date back to antiquity; namely, to treatises like the Timaeus of Plato, in his reflections on what the Greeks called: Chora / Khora (i.e. 'space'), or in the Physics of Aristotle (Book IV, Delta) in the definition of topos (i.e. place), or even in the later 'geometrical conception of place' as 'space qua extension' in the Discourse on Place (Qawl fi al-Makan) of the 11th century Arab polymath Ibn al-Haytham (Alhazen). Many of these classical philosophical questions were discussed in the Renaissance and then reformulated in the 17th century, particularly during the early development of classical mechanics. In Isaac Newton's view, space was absolute - in the sense that it existed permanently and independently of whether there were any matter in the space. Other natural philosophers, notably Gottfried Leibniz, thought instead that space was a collection of relations between objects, given by their distance and direction from one another. In the 18th century, the philosopher and theologian George Berkeley attempted to refute the 'visibility of spatial depth' in his Essay Towards a New Theory of Vision. Later, the metaphysician Immanuel Kant said neither space nor time can be empirically perceived, they are elements of a systematic framework that humans use to structure all experiences. Kant referred to 'space' in his Critique of Pure Reason as being: a subjective 'pure a priori form of intuition', hence it is an unavoidable contribution of our human faculties.

In the 19th and 20th centuries mathematicians began to examine non-Euclidean geometries, in which space can be said to be curved, rather than flat. According to Albert Einstein's theory of general relativity, space around gravitational fields deviates from Euclidean space. Experimental tests of general relativity have confirmed that non-Euclidean space provides a better model for the shape of space.
