what is the denver ii developmental screening test
Denver Developmental Screening Test The DENVER II (1992) is a revision and update of the Denver Developmental Screening Test, DDST (1967).[6][7] Both were designed for use by the clinician, teacher, or other early childhood professional to monitor the development of infants and preschool-aged children. Doing so, enables the clinician to identify children whose development deviates significantly from that of other children warranting further investigation to determine if there exists a problem requiring treatment. The tests cover four general functions: personal social (such as smiling), fine motor adaptive (such as grasping and drawing), language (such as combining words), and gross motor (such as walking). Ages covered by the tests range from birth to six years. Since its publication the test has enjoyed widespread popularity as reflected by its use in many of this nation's medical schools.
Trinity (nuclear test) Trinity was the code name of the first detonation of a nuclear weapon. It was conducted by the United States Army at 5:29 a.m. on July 16, 1945, as part of the Manhattan Project. The test was conducted in the Jornada del Muerto desert about 35 miles (56Â km) southeast of Socorro, New Mexico, on what was then the USAAF Alamogordo Bombing and Gunnery Range (now part of White Sands Missile Range). The only structures originally in the vicinity were the McDonald Ranch House and its ancillary buildings, which scientists used as a laboratory for testing bomb components. A base camp was constructed, and there were 425 people present on the weekend of the test.
