Solar energy

Solar energy is radiant light and heat from the Sun harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture and artificial photosynthesis.

It is an important source of renewable energy and its technologies are broadly characterized as either passive solar or active solar depending on the way they capture and distribute solar energy or convert it into solar power. Active solar techniques include the use of photovoltaic systems, concentrated solar power and solar water heating to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air.

The large magnitude of solar energy available makes it a highly appealing source of electricity. The United Nations Development Programme in its 2000 World Energy Assessment found that the annual potential of solar energy was 1,575–49,837 exajoules (EJ). This is several times larger than the total world energy consumption, which was 559.8 EJ in 2012.

Solar Energy (journal)

Solar Energy is a peer-reviewed scientific journal covering research on solar energy such as photovoltaics and solar heating, but also its indirect usages like wind power or bioenergy. It is published by Elsevier on behalf of the International Solar Energy Society. The editor-in-chief is Yogi Goswami. According to the Journal Citation Reports, the journal has a 2013 impact factor of 3.541.

Mali (ⁱ/ˈmɑːli/; French: [maˈli]), officially the Republic of Mali (French: République du Mali), is a landlocked country in West Africa. Mali is the eighth-largest country in Africa, with an area of just over 1,240,000 square kilometres (480,000 sq mi). The population of Mali is 14.5 million. Its capital is Bamako. Mali consists of eight regions and its borders on the north reach deep into the middle of the Sahara Desert, while the country's southern part, where the majority of inhabitants live, features the Niger and Senegal rivers. The country's economy centers on agriculture and fishing. Some of Mali's prominent natural resources include gold, being the third largest producer of gold in the African continent, and salt. About half the population lives below the international poverty line of $1.25 (U.S.) a day. A majority of the population (55%) are non-denominational Muslims.

Present-day Mali was once part of three West African empires that controlled trans-Saharan trade: the Ghana Empire, the Mali Empire (for which Mali is named), and the Songhai Empire. During its golden age, there was a flourishing of mathematics, astronomy, literature, and art. At its peak in 1300, the Mali Empire covered an area about twice the size of modern-day France and stretched to the west coast of Africa. In the late 19th century, during the Scramble for Africa, France seized control of Mali, making it a part of French Sudan. French Sudan (then known as the Sudanese Republic) joined with Senegal in 1959, achieving independence in 1960 as the Mali Federation. Shortly thereafter, following Senegal's withdrawal from the federation, the Sudanese Republic declared itself the independent Republic of Mali. After a long period of one-party rule, a coup in 1991 led to the writing of a new constitution and the establishment of Mali as a democratic, multi-party state.

Malič (Serbian Cyrillic: Малич) is a mountain in western Serbia, near the town of Ivanjica. Its highest peak has an elevation of 1,110 meters above sea level.

Mali (cartoonist)

T. R. Mahalingam, better known by his pen-name Mali, was an illustrator and cartoonist from Tamil Nadu, India, in the pre-independence era. He was the Tamil Press's first caricaturists, according to Chennai historian S. Muthiah in The Hindu. Muthiah has written elsewhere that Mali did as much with his strokes for Vikatan as its celebrated editor Kalki Krishnamurthy did with his words.

Mali published his drawings in the Indian Express in the 1930s, and first made his name at the Free Press Journal 'before being immortalised in the pages of Ananda Vikatan, the first popular Tamil periodical'. He also did cartoons for the Vikatan group's English-language Merry Magazine, where he became the editor in 1935. He is said to have left the editorial nitty-gritty to his assistant editor, while continuing to illustrate such humorous serials as 'Private Joyful in Madras' (The magazine shut down in c. 1935 or 1936).

While it was the writer and poet Subramanya Bharathi who first introduced cartoons to Tamil journalism, it was Ananda Vikatan that made them truly popular. As cartoonist and senior artist at Ananda Vikatan, Mali was thus a key influence on a second generation of cartoonists. Gopulu and Silpi were illustrators he mentored at Vikatan.
