Cattle

Cattle is colloquially referred to as cows, are disciplined ungulates, a member of the subfamily Bovina of the family Bovidae. They are raised as livestock for meat dairy products (milk), leather and as draught animals. In some countries, such as India, they are honored in religious ceremonies and revered. It is expected that there are 1.4 billion head of cattle in the world today.

Cattle were originally known by Carolus Linnaeus as three separate species. These were Bos taurus, the European cattle, including similar types from Africa and Asia, Bos indicus, the zebu,and the extinct Bos primigenius, the aurochs. The aurochs is ancestral to together zebu and European cattle. More newly these three have increasingly been grouped as one species, sometimes using the names Bos primigenius taurus, Bos primigenius indicus and Bos primigenius. Complicating the matter is the capacity of cattle to interbreed with other closely related species. Hybrid individuals and even breeds exist, not only between European cattle and zebu but also with yaks, banteng, gaur, and bison, a cross-genera fusion. Cattle cannot effectively be bred with water buffalo or African buffalo.

Real estate

Real estate or fixed property is a legal term that encompasses land along with anything permanently affixed to the land, such as buildings. Real estate is often considered synonymous with real property, in contrast with personal property. However, for technical purposes, some people prefer to distinguish real estate, referring to the land and fittings themselves, from real property, referring to ownership rights over real estate. The terms real estate and real property are used mainly in common law, while civil law jurisdictions refer in its place to immovable property.

In law, the word real means relating to a thing, as well-known from a person. Thus the law broadly distinguishes between real possessions and personal property. The conceptual difference was between immovable property, which would transport title along with the land, and changeable property. In most advanced economies, the main source of capital used by individuals and small companies to purchase and get enhanced land and buildings is mortgage loans, bank loans for which the real property itself constitutes collateral.

Solar wind

The solar wind is a stream of charged particles which are expelled from the upper atmosphere of the sun. It consists mostly of high-energy electrons and protons that are able to get away the sun's gravity in part because of the high temperature of the corona and the high kinetic energy particles gain through a process that is not well understood at this time.

They are directly related to the solar wind, together with geomagnetic storms that can knock out power grids on Earth, auroras and the plasma tail of a comet always pointing away from the sun. While early models of the solar wind used primarily thermal energy to accelerate the material, by the 1960s it was clear that thermal hurrying alone cannot account for the high speed solar wind. Some additional acceleration mechanism is required, but is not presently known, but most likely relates to magnetic fields in the solar atmosphere. The solar wind is answerable for the overall shape of Earth's magnetosphere, and fluctuations in its speed, density, direction, and entrained magnetic field powerfully affect Earth's local space environment.

Sql

SQL generally expanded as Structured Query Language. The first report of SQL was developed at IBM by Donald D. Chamberlin and Raymond F. Boyce in the early 1970s. This version, initially called SEQUEL, was planned to manipulate and retrieve data stored in IBM's original relational database creation, System R. The SQL language was later formally standardized by the American National Standards Institute (ANSI) in 1986. Later versions of the SQL standard have been released as International Organization for Standardization (ISO) standards.Originally intended as a declarative query and data manipulation language, variations of SQL have been created by SQL database management system (DBMS) vendors that add procedural constructs, control-of-flow statements, user-defined data types, and various other language extensions. With the release of the SQL:1999 standard, many such extensions were formally adopted as part of the SQL language via the SQL continual Stored Modules portion of the standard. In SQL first, there are the standard Data Manipulation Language (DML) basics. DML is the subset of the language used to insert, update and delete data.
