Transmission lines are conductors that transmit energy, including electricity, acoustic energy, and electromagnetic energy. They can be designed to carry large or small quantities and operate in extreme conditions. Loss and interference can be problems, but manufacturers take measures to minimize them. The science behind transmission lines dates back to the 1800s and played a […]
A transmission dynamometer measures the torque a transmission can handle without failing. Choosing the right one depends on the job and available space. It can detect leaks and faults, and heavy-duty versions are ideal for large trucks. Manual transmissions require specific testing procedures. A transmission dynamometer, commonly called a transmission dynamometer, is a piece of […]
Acoustic transmission is when sound waves pass through a material, causing noise on both sides. Engineers use Sound Transmission Class (STC) ratings to control sound transmission levels. Materials with higher STC ratings are more effective. Designers can control acoustic transmission by using materials that absorb sound waves, mass to deaden sound, or an airspace to […]
Non-synchronous transmissions are found in heavy-duty equipment and require double clutching and proper engine speed to shift. In contrast, passenger vehicles use fully synchronized transmissions with a cone and collar system to mesh gears. Non-synchronous transmissions are stronger and capable of pulling heavier loads. A non-synchronous transmission is typically found in commercial, agricultural, and heavy-duty […]
Letters of Conveyance are official documents used in international trade to describe securities remittance details, including shipment contents, transport means, and sender/receiver information. They may also include departure and delivery dates, carrier names, and tracking numbers. These letters facilitate processing at customs checkpoints and help law enforcement verify shipment contents. Letters of Conveyance are documents […]
Secure transmission is the process of protecting data as it is transferred from one point to another. It is crucial for businesses to secure data, such as customer information and financial data, through encryption and other security measures to prevent interception and duplication. A good secure transmission strategy includes preventing spoofing and identifying physical breaches. […]
Data is sent from one computer to another through synchronous or asynchronous transmission. Characters are made up of bits and are transmitted with a START, PARITY, and STOP bit. Asynchronous transmission is preferred for less frequent data and is simpler and cheaper than synchronous transmission. When data needs to be sent from one computer to […]
Data transmission involves transporting information using various methods, including audio, video, and text. These methods have become more efficient with advances in technology, such as VoIP and video conferencing. The use of these methods continues to expand as new technology emerges. Data transmission is any process that allows information of any kind to be transported […]
Vertical transmission of disease from mother to infant during perinatal period can occur through placental transmission, exposure to bodily fluids during labor, and breast milk. HIV, hepatitis C, and toxoplasmosis are examples of vertically transmitted diseases. Precautions and tests during pregnancy can reduce risks, and a C-section may be recommended in some cases. Mothers can […]
Flexible AC transmission systems (FACTS) improve power transmission capacity and reliability, optimizing existing systems and reducing the need for new equipment. FACTS technology includes hardware and software that can control voltage and current flow, improve power quality, and reduce electrical losses. It can be installed within existing substations or transmission facilities, reducing construction time and […]
Transmission electron microscopy (TEM) uses beams of electrons to image very thinly sectioned samples at high resolutions. TEMs have played important roles in virology, cancer research, materials study, and microelectronics R&D. The first TEM prototype was built in 1931, and the technology was refined over the following decades. Scanning transmission electron microscopy (STEM) was developed […]
Broadcast and sound engineers install, test, operate and repair electronic equipment used for broadcasting. They must have knowledge of audio, computer, and radio frequency engineering. They maintain digital broadcast automation systems, recording equipment, and radio towers. The median salary for broadcast engineers was $30,690 USD in 2006. Education requirements vary, but a degree in electrical […]
Factors limiting electricity transmission include distance, transmission power, materials, and location. Energy loss occurs during transmission due to Joule’s law and corona discharge. Thick cables and strategic additions like capacitor banks and transformers help manage power flow and minimize loss. Extension cords increase loss, limiting transmission. There are several key factors that limit the transmission […]
Neuromuscular transmission occurs at the neuromuscular junction, where nerves release acetylcholine to trigger muscle movement. Disorders can cause paralysis or weakness, and drugs can interrupt transmission. Myasthenia gravis is a potential disorder, and knockout studies in mice offer insight into human treatment. In the process of neuromuscular transmission, nerves send a signal to muscle fibers […]
To prevent the spread of herpes, abstain from sex, use condoms, limit sexual partners, and avoid sexual contact during outbreaks. Pregnant women can have a C-section or use antiviral medication to avoid spreading the virus to their baby. Kissing can also spread herpes. Herpes is mainly spread through sexual contact. If you want to avoid […]
Horizontal transmission is the spread of infectious diseases from one organism to another through direct or indirect contact. It is more common than vertical transmission, which only occurs from parent to offspring. Pathogens can be transmitted through direct contact, contaminated surfaces, or carriers such as mosquitoes. Horizontal transmission is a term used to describe one […]
To become a transmission mechanic, one must complete post-secondary training, gain related work experience, obtain certification, and go through the job interview process. This career requires mechanical skills and working with tools. Certification exams and work experience are required, and career advancement opportunities include specialization in a specific engine make or size. There are four […]
