AP World History: Modern was designed to help students develop a greater understanding of the evolution of global processes and contacts as well as interactions between different human societies. The course advances understanding through a combination of selective factual knowledge and appropriate analytical skills.
[25] [26] [27] An alternative technique with the phoropter requires the use of a "clock dial" or "sunburst" chart to determine the astigmatic axis and power. [28] [29] A keratometer may also be used to estimate astigmatism by finding the difference in power between the two primary meridians of the cornea.
A recent development are computer-controlled stigmators, which usually use the Fourier transform of the image to find the ideal stigmator setting. The Fourier transform of an astigmatic image is usually elliptically shaped. [13] For a stigmatic image, it is round, this property can be used by algorithms to reduce the astigmatic aberration. [4]
This technique was first applied by Davis. In peribulbar block, local anaesthetic is injected to the peripheral spaces of the orbit. The anaesthetic diffuses into the muscle cone and eyelids, causing global and orbicularis akinesia and anaesthesia. After injection, orbital compression is applied for around 15 minutes.

Woodblock printing or block printing is a technique for printing text, images or patterns used widely throughout East Asia and originating in China in antiquity as a method of printing on textiles and later on paper.
Lectures on the Philosophy of History, also translated as Lectures on the Philosophy of World History [1] (LPH; German: Vorlesungen über die Philosophie der Weltgeschichte, VPW), is a major work by Georg Wilhelm Friedrich Hegel (1770–1831), originally given as lectures at the University of Berlin in 1822, 1828, and 1830.
When it was introduced in the French newspaper Le Figaro in June 1833, the term 'phénakisticope' was explained to be from the root Greek word φενακιστικός phenakistikos (or rather from φενακίζειν phenakizein), meaning "deceiving" or "cheating", [2] and ὄψ óps, meaning "eye" or "face", [3] so it was probably intended loosely as 'optical deception' or 'optical illusion'.
Woodcut is a relief printing artistic technique in printmaking in which an image is carved into the surface of a block of wood, with the printing parts remaining level with the surface while the non-printing parts are removed, typically with gouges. The areas to show 'white' are cut away with a knife or chisel, leaving the characters or image ...
