National Crime Victimization Survey (NCVS)
The National Crime Victimization Survey (NCVS) began in 1972 as an attempt to gather information about crimes not reported to the police, including rape, robbery, assault, burglary, theft, and motor-vehicle theft.
Unlike data derived from police reports, NCVS data comes from survey interviews.
The survey includes questions about both victims and offenders (race, age, educational level), as well as questions about the actual crime: time, place, weapons used,

Austria in the 17th Century: Valid Kings
The kings of the Austrian dynasty in the 17th century were characterized by a weak character and lack of political vocation, leading to the delegation of government to the validos (the king’s trusted person, who, without an official position, exercised power). Top validos were the Duke of Lerma, favorite of Philip III, and the Count-Duke of Olivares, valido of Philip IV.
The validos had to cope with the slow decline of Hispanic hegemony, motivated by the depletion

Joint Mobility
Joint mobility exercises involve mobilizing the major joints of the body through their full range of motion. The goal is to help heat and circulate synovial fluid. These movements must be controlled, continuous, smooth, and comfortable.
Examples: shoulder elevations, trunk rotations, hip circles, knee flexion and extension.
Low-Impact Activities
Low-impact activities are low-intensity exercises that exclude jumps and therefore do not require great

Respiratory System Anatomy
Area of Conduct
Formed by a series of interconnected cavities and tubes: nose, pharynx, larynx, trachea, bronchi, bronchioles, and terminal bronchioles. These structures conduct air into the lungs.
Respiratory Tract
The respiratory tract is woven into the lungs where gas exchange occurs, covering the respiratory bronchioles, alveolar ducts, alveolar sacs, and alveoli.
Nose
The internal structures of the nose fulfill these functions:
- Filter, warm, and humidify the incoming air.
