Patterns in nature are visible regularities of form found in the natural world. These patterns recur in different contexts and can sometimes be modelled mathematically . Natural patterns include symmetries , trees , spirals , meanders , waves , foams , tessellations , cracks and stripes. [ 1 ]
Overview, including some physiological parameters, of the human circadian rhythm ("biological clock").. Chronobiology is a field of biology that examines timing processes, including periodic (cyclic) phenomena in living organisms, such as their adaptation to solar- and lunar-related rhythms. [1]
The best studied rhythm in chronobiology is the circadian rhythm, a roughly 24-hour cycle shown by physiological processes in all these organisms.The term circadian comes from the Latin circa, meaning "around" and dies, "day", meaning "approximately a day."
The upper parts show; a) two cells of 3:2, beginning on beats 1 and 3 (Play ⓘ); b) the same, beginning on beats 2 and 4 (Play ⓘ); c) one cell of a) and one of b) giving d) the standard bell pattern notation (Play ⓘ) The most commonly used key pattern in sub-Saharan Africa is the seven-stroke figure known in ethnomusicology as the standard ...
A composite rhythm is the durations and patterns (rhythm) produced by amalgamating all sounding parts of a musical texture. In music of the common practice period , the composite rhythm usually confirms the meter , often in metric or even-note patterns identical to the pulse on a specific metric level.
A circadian rhythm (/ s ər ˈ k eɪ d i ə n /), or circadian cycle, is a natural oscillation that repeats roughly every 24 hours. Circadian rhythms can refer to any process that originates within an organism (i.e., endogenous ) and responds to the environment (is entrained by the environment).
Uluṟu-Kata Tjuṯa National Park, sacred landscape of the aboriginal Australian, classified as "cultural landscape" by Unesco. The World Heritage Committee's adoption and use of the concept of 'cultural landscapes' has seen multiple specialists around the world, and many nations identifying 'cultural landscapes', assessing 'cultural landscapes', heritage listing 'cultural landscapes ...
Traditional sub-Saharan African harmony is a music theory of harmony in sub-Saharan African music based on the principles of homophonic parallelism (chords based around a leading melody that follow its rhythm and contour), homophonic polyphony (independent parts moving together), counter-melody (secondary melody) and ostinato-variation (variations based on a repeated theme).
