factors that affect the occupational exposure to whole-body vibration include the frequency of vibrations, the magnitude of vibrations, the daily exposure to vibrations, the standing or seating posture of the operator, the direction of the vibration, and how tightly coupled the human is to the source of the vibration.
assistive technology devices have been created to enable people with disabilities to use modern touch screen mobile computers such as the ipad, iphone and ipod touch. the pererro is a plug and play adapter for ios devices which uses the built in apple voiceover feature in combination with a basic switch.
tat-8 did not have the screen conductor over the vast majority of its length, as the threat of shark attack was deemed be small over the majority of the route. because the canary island cable was the first fiber optic cable and not coaxial cable, the electrical interference shielding for the high voltage supply lines was removed.
sepro-sizetec screens are used for a variety of particle size separation and dewatering duties in mineral processing and aggregate applications. in mineral processing applications, particle size separation is of utmost importance in order to optimize crushing, grinding and gravity separation as well as many other processes.
cinerama is a widescreen process that originally projected images simultaneously from three synchronized 35 mm projectors onto a huge, deeply curved screen, subtending 146 of arc. clarification needed the trademarked process was marketed by the cinerama corporation.it was the first of a number of novel processes introduced during the 1950s, when the movie industry was reacting to .
the history of watches began in 16th century europe, where watches evolved from portable spring-driven clocks, which first appeared in the 15th century. the watch which developed from the 16th century to the mid 20th century was a mechanical device, powered by winding a mainspring which turned gears and then moved the hands, and kept time with a rotating balance wheel.

accelerometers are also used for machinery health monitoring to report the vibration and its changes in time of shafts at the bearings of rotating equipment such as turbines, pumps, fans, rollers, compressors, or bearing fault which, if not attended to promptly, can lead to costly repairs. accelerometer vibration data allows the user to monitor machines and detect these faults before the .
a hygrometer is an instrument used to measure the amount of humidity and water vapour in the atmosphere, in soil, or in confined spaces. humidity measurement instruments usually rely on measurements of some other quantity such as temperature, pressure, mass, a mechanical or electrical change in a substance as moisture is absorbed.
bronchiolitis typically presents in children under two years old and is characterized by a constellation of respiratory symptoms that consists of fever, rhinorrhea, cough, wheeze, tachypnea and increased work of breathing such as nasal flaring or grunting that develops over one to three days. crackles or wheeze are typical findings on listening to the chest with a stethoscope.
the asphalt plant is mainly composed of cold aggregate supply system, drum dryer, coal burner, coal feeder, dust collector, hot aggregate elevator, vibrating screen, filler supply system, weighing and mixing system, asphalt storage, bitumen supply system. all these components have characteristics that impact not only the overall quality of the .
vibration isolation is the process of isolating an object, such as a piece of equipment, from the source of vibrations. vibration is undesirable in many domains, primarily engineered systems and habitable spaces, and methods have been developed to prevent the transfer of vibration to such systems. vibrations propagate via mechanical waves and certain mechanical linkages conduct vibrations more efficiently than others. passive vibration isolation makes use of materials and mechanical linkages tha
laryngopharyngeal reflux lpr is the retrograde flow of gastric contents into the larynx, oropharynx and/or the nasopharynx. lpr causes respiratory symptoms such as cough and wheezing and is often associated with head and neck complaints such as dysphonia, globus pharyngis, and dysphagia. lpr may play a role in other diseases, such as sinusitis, otitis media, and rhinitis, and can be a .
a security alarm is a system designed to detect intrusion – unauthorized entry – into a building or other area. security alarms are used in residential, commercial, industrial, and military properties for protection against burglary or property damage, as well as personal protection against intruders.security alarms in residential areas show a correlation with decreased theft.
