AGRICULTURE |
|
Agriculture (a term which encompasses farming) is the art, science or practice of producing food, feed, fiber and many other desired goods by the systematic raising of plants and animals. Agri is from Latin ager ("a field"), and culture is from Latin cultura, meaning "cultivation" in the strict sense of tillage of the soil. Thus a literal reading of the English word yields tillage of the soil of a field. In actual usage, Agriculture denotes a broad array of activities essential to food and material production, including all techniques for raising and processing livestock (see Animal husbandry) no less than those essential to crop planting and harvesting.

CANCER - GENERAL |
|
Cancer is a class of diseases or disorders characterized by uncontrolled division of cells and the ability of these cells to invade other tissues, either by direct growth into adjacent tissue through invasion or by implantation into distant sites by metastasis. This unregulated growth is caused by damage to DNA, resulting in mutations to genes that encode for proteins controlling cell division. Many mutation events may be required to transform a normal cell into a malignant cell. These mutations can be caused by chemicals or physical agents called carcinogens, by close exposure to radioactive materials, or by certain viruses that can insert their DNA into the human genome. Mutations occur spontaneously, or are passed down generations as a result of germ line mutations.

CRITICAL CARE |
|
Intensive Care Medicine or critical care medicine is concerned with providing greater than ordinary medical care and observation to people in a critical or unstable condition.
People requiring intensive care include those after major surgery, with severe head trauma, life-threatening acute illness, respiratory insufficiency, coma, haemodynamic insufficiency, severe fluid imbalance or with the failure of one or more of the major organ systems (life-critical systems or others).

ECONOMIC ANALYSIS |
|
Economic base analysis was developed by Robert Murray Haig in his work on the Regional Plan of New York in 1928. Briefly, activities in an area divide into two categories basic and non-basic. Basic industries are those exporting from the region; non-basic (or service) industries support basic industries. Because of data problems, it is not practical to study industry output and trade flows to and from a region. As an alternative, basic and non-basic concepts are operationalized using employment data.

HORSES |
|
The horse (Equus caballus or Equus ferus caballus) is a sizeable ungulate mammal, one of ten modern species of the genus Equus. Horses have long been one of the most economically important domesticated animals, and have played an important role in the transport of people and cargo for thousands of years. Most notably, horses can be ridden by a person perched on a saddle attached to the animal, and are also widely harnessed to pull objects like wheeled vehicles or plows. In some human cultures, horses are also widely used as a source of food. Though isolated domestication may have occurred as early as 4500 BC, clear evidence of widespread use by humans dates to no earlier than 2000 BC, as evidenced by the Sintashta chariot burials, thus firmly establishing the domestication of the horse.

OPHTHALMOLOGY |
|
Ophthalmology is the branch of medicine which deals with the diseases of the eye and their treatment. The word ophthalmology comes from the Greek roots ophthalmos meaning eye and logos meaning word; ophthalmology literally means "the science of eyes." As a discipline it applies to animal eyes also, since the differences from human practice are surprisingly minor and are related mainly to differences in anatomy or prevalence, not differences in disease processes. By convention the term ophthalmologist is more restricted and implies a medically trained specialist. Since ophthalmologists perform operations on eyes, they are generally categorized as surgeons.

ORTHOPEDICS |
|
Orthopedics - The branch of medicine that deals with the prevention or correction of injuries or disorders of the skeletal system and associated muscles, joints, and ligaments. Orthopedic surgery or orthopedics (Commonwealth: "orthopaedics") is the branch of surgery concerned with acute, chronic, traumatic, and recurrent injuries and other disorders of the musculoskeletal system, its muscular and bone parts. Apart from the mechanical considerations, it also is concerned with the pathology, genetics, intrinsic, extrinsic, and biomechanical factors involved.
|
PATHOLOGY |
|
Pathology (from Greek pathos, feeling, pain, suffering; and logos, study of; see also -ology) is the study of the processes underlying disease and other forms of illness, harmful abnormality, or dysfunction. Within biology, it means specifically the study of the structural and functional changes in cells, tissues and organs that underlie disease. Another name for pathology is laboratory medicine.
|
RADIOLOGY |
|
Radiology is the medical specialty that utilizes and interprets imaging technologies to diagnose disease. Traditionally it was the branch of medical science dealing with the medical use of X-rays emitted by X-ray machines or other such radiation devices for the purpose of obtaining visual information as part of medical imaging. Radiologists now also use all other imaging technologies (such as ultrasound, computed tomography (CT) and magnetic resonance imaging) to diagnose or treat disease. Interventional radiology is the performance of (usually minimally invasive) medical procedures with the help of medical imaging.

SURGERY - ORTHOPEDIC |
|
Orthopedic surgery or orthopedics (Commonwealth: "orthopaedics") is the branch of surgery concerned with acute, chronic, traumatic, and recurrent injuries and other disorders of the musculoskeletal system, its muscular and bone parts. Apart from the mechanical considerations, it also is concerned with the pathology, genetics, intrinsic, extrinsic, and biomechanical factors involved.

URGENT / EMERGENCY CARE |
|
Urgent care is the delivery of ambulatory care in a facility dedicated to the delivery of unscheduled, walk-in care outside of a hospital emergency department. The initial urgent care centers opened in the 1970s. Since then this sector of the healthcare industry has rapidly expanded to an approximately 17,000 centers. Many of these centers have been started by entrepreneurial physicians who have responded to the public need for convenient access to unscheduled medical care. Other centers have been opened by hospital systems, seeking to attract patients. Much of the growth of these centers has been fueled by the significant savings that urgent care centers provide over the care in a hospital emergency department. Many managed care organizations (MCOs) now encourage their customers to utilize the urgent care option.

VETERINARY |
|
Veterinary medicine is the application of medical, diagnostic, and therapeutic principles to companion, domestic, exotic, wildlife, and production animals. Veterinary Science is concerned with the scientific basis of animal production, health and disease. It requires the acquisition and application of scientific knowledge in several disciplines and uses technical skills towards the solution of animal production, health, management and welfare problems.
