Hydrogels are three-dimensional polymeric networks filled with water. The water content can reach as high as 90-99% depending on the polymer concentration. It contains polymers that are attracted to water, they swell and hold large amounts of water while maintaining their structure due to chemical or physical cross-linking of individual polymer chains. The physical cross-linked hydrogels are easily pulled and relaxed, like a rubber band. The chemically cross-linked hydrogels avoid deformation. The behaviour of hydrogels is typically viscoelastic which is associated with the water and the movement of polymer networks in fluids. Similar to other polymers, there are natural and man-made hydrogels. The man-made hydrogels are also known as synthetic, this allows the hydrogels to have a longer service life, hold more water, and have greater strength.
There are many types of hydrogels. The most common ones are pH-sensitive hydrogels, which respond to pH changes in the environment. Temperature-sensitive hydrogels, which are affected by how hot or cold the environment is. Electro-sensitive hydrogels, which either shrink or expand when an electric field is applied. Lastly, the light-responsive hydrogels respond to light.
In many ways hydrogels are similar to our bodies because the human body is made out of mainly water and matrix materials that are surrounded by cells. This is why hydrogels can be used in tissue engineering. Hydrogels are filled with water so they mimic tissue environments, this means they are optimal to deliver cells and repair damaged tissue.

Electrowinning
Electrowinning is a manufacturing process for making metals from a solution containing dissolved metal. The process involves passing an electrical current from an inert electrode through the solution containing the metal, to plate the metal to another electrode. Also called electroplating, it is a common process for producing metals like copper, cobalt, nickel, zinc, aluminum, and gold among others. Electrowinning is one of the last processes in metal production. It commonly follows leaching which is a process that dissolves minerals into a solution.
The electrical current is passed from the inert electrode, called the anode, and passes through the metal containing solution, called the electrolyte, and the metal is plated on another electrode, called the cathode. The ability to plate a metal depends on the reduction potential. The reduction potential depends on the many factors such as the metal in question, the solution temperature, the pH of the solution and other factors. The rate at which the metal can be produced depends on the amount of current being passed through the solution.
Industrially the process is made up of a square cathode with equal sized anodes on each side so that the metal can be plated evenly on both sides of the cathode. A cell consists of alternating anodes and cathodes, starting and ending with anodes. A production plant consists of many cells allowing for production of lots of metal.

Asia Pacific Democrat Union
The Asia Pacific Democrat Union (APDU), is in international political centre-right, right group of political parties in the Asia Pacific Region. This union is tied and related to the International Democrat Union that is based in Munich ,Germany, the (APDU) Is labelled as a regional union on the International Democrat Union (IDU) Website.
The Asia Pacific Democrat Union aims to provide a place in which political parties that have similar beliefs can exchange there views on matters of policy and interest so that ideas can be shared between party's so that centre-right ideals can be spread and be encouraged all over the world.
This Union currently has 15 members, ranging from Bangladesh to El Salvador, the current chairperson is Ranil Wickramasinghe the former Sri Lankan Prime Minister Serving in this position since 2016. Tenzin Dargyalb Khangsar (Canada) From Tibet serves as vice chairman of the union making him the first person of Tibetan ancestry to represent the organisation. This lead to Controversy with China disagreeing with this Choice due to Tenzin Dargyalb Khangsar (Canada) previously denouncing China's claims on Tibet. BNP secretary general Mirza Fakhrul Islam Alamgir (India) has also been chosen as vice chairman and Hassan Latheef (Maldives).
The Asia Pacific Democrat Union (APDU), does not have a separate website but you can email, and there party address currently is Sirikotha 400 Kotte Road, Pita Kotte Sri Jayawardenepura, Sri Lanka witch is also the headquarters of the United National Party (UNP).
Current party members and affiliates include a range of party in government and opposition including the Liberal party of Australia, The Republican Party of the United States and even the Kuomintang in Republic of China (Taiwan). A full list of party members can be found Bellow.
Emperor Kōtoku
Emperor Kôtoku was the 36th emperor of Japan according to the traditional counting. He was also called "Taika," for "Great Change." He ruled from 645 AD - 654 AD. He made the Taika Reforms, which changed parts of Tang dynasty ways of thinking about politics, running the government, and doing rituals for the Japanese court.
Before he was the Emperor, he was called Prince Karu. He became emperor in 645 AD after his sister, Empress Kôgyoku, abdicated in his favor. That means she quit being Empress and gave Karu the throne. Some historians say that Empress Kôgyoku's son, Prince Naka no Oe, asked her to abdicate. Prince Naka no Oe who would later become Emperor Tenji.
With the Taika Reforms, Kôtoku changed the way court officers wore clothes in 647. People of different rank (level of importance) wore different clothes. Kôtoku also said that the government had a monopoly on mined iron ore, meaning that no one else was allowed to mine iron ore. Before that, the Wakebe clan had mined iron ore.
After Kôtoku died in 654, Kôgyoku became Empress again, but this time she was called Empress Saimei.
