ARM

The ARM architecture (Advanced RISC Machine or Acorn RISC Machine) is a 32-bit RISC processor architecture developed by ARM Limited that is widely used in a number of embedded designs. Due to their power saving features, ARM CPUs are dominant in the mobile electronics market, where low power consumption is a critical design goal.

Today, the ARM family accounts for over 75% of all 32-bit embedded CPUs, making it one of the most prolific 32-bit architectures in the world. ARM CPUs are found in all corners of consumer electronics, from portable devices to computer peripherals. Important branches in this family include Marvell's XScale and the Texas Instruments OMAP series.

Ice

Ice is the name given to any one of the 14 known solid phases of water. Though in non-scientific contexts, it usually describes ice Ih, which is the most abundant of these phases. It is a crystalline solid, which can appear transparent or an opaque bluish-white color depending on the presence of impurities such as air. The addition of other materials such as soil may further alter appearance. The most common phase transition to ice Ih occurs when liquid water is cooled below 0 °C (273.15 K, 32 °F) at standard atmospheric pressure. However, it can also deposit from a vapor with no intervening liquid phase such as in the formation of frost. Ice appears in varied forms such as hail, ice cubes, and glaciers. It plays an important role with many meteorological phenomena. The ice caps of the polar regions are of significance for the global climate and particularly the water cycle.

Neem cake

Neem cake natural manure is the by-product obtained in the process of cold pressing of Neem fruits and kernels, and the solvent removal process for neem oil cake. It is a potential source of organic manure under the Bureau of India Standards, Neem has established considerable potential as a fertilizer. For this purpose, neem cake and neem leaves are particularly promising. Puri , in his book on neem has given details about neem seed cake as manure and nitrification inhibitor. The author has described that after processing neem cake can be used for partial replacement of poultry and cattle feed.

People

People are a group of humans, either with not mentioned traits, or specific characteristics (e.g. the people of Spain or the people of the Plains).The term people is often used in English as the suppletive plural of person. However, the word persons is sometimes used in place of people, particularly when it would be ambiguous with its collective sense (e.g. missing persons instead of missing people). The term people can together refer to all humans or it can be used to identify the citizens of a nation, or members of a tribe, ethnic, or religious group. People of color is a phrase used to describe people with skin color darker than that of white people.

Fashionable watches

At the end of the 20th century, Swiss watch makers were seeing their sales go down as analog clocks were considered outmoded. They joined forces with designers from many countries to reinvent the Swiss watch.
The result was that they could considerably decrease the pieces and production time of an analog watch. In fact it was so cheap that if a watch broke it would be cheaper to fling it away and buy a new one than to repair it. One of these Swiss watch manufacturers started a new brand, Swatch, and called graphic designers to redesign a new annual collection.

Social status

In many societies, people of high rank set aside special items of clothing or decoration for themselves as symbols of their social status. In ancient times, only Roman senators could wear garments dyed with Tyrian purple; only high-ranking Hawaiian chiefs could wear feather cloaks and palaoa or imprinted whale teeth. Under the Travancore kingdom of Kerala (India), lower caste women caste had to pay a tax for the right to cover their upper body. In China before the establishment of the republic, only the monarch could wear yellow. In many cases throughout history, there have been intricate systems of sumptuary laws regulating who could wear what. In other societies, no laws prohibit lower-status people wearing high status garments, but the high cost of status garments effectively limits purchase and display. In current Western society, only the rich can afford haute couture. The threat of social exclusion may also limit garment choice.
