It can lead to serious complications if left untreated, including infertility and blindness. Treatment involves antibiotics and safe sex practices are recommended to prevent re-infection. Chlamydia trachomatis is a human pathogen that causes the sexually transmitted disease […]

What’s boat building?

[ad_1] Boat building requires skills in carpentry, welding, engine building, electronics, plumbing, and adherence to local laws. Boat building has been a part of human history, from basic canoes to advanced ships. Wooden boats are still popular and require durable lumber and a sealing finish. The hull is typically built with skeletal structures and outer […]

What’s Britannia Metal?

[ad_1] Britannia metal is a blend of tin, antimony, and copper used for household items. Elkington & Company developed electroplating, making silver-plated Britannia metalware successful. It’s stronger than tin, easier to work with, and commonly used for silver-plated utensils and teapots. Britannia metal is a blend of tin, food and copper commonly used in household […]

What’s a Screw Feeder?

[ad_1] Auger feeders accurately measure or feed bulk materials using the auger principle. They can handle coarse-grained bulk or thick slurry materials and are controlled by servo motors for precise stop-start and speed control. There are two basic types: volumetric and gravimetric. An auger feeder is a device used in various industries to accurately measure […]

What’s a Screw Feeder?

[ad_1] Auger feeders accurately measure and transport coarse-grained bulk or thick slurry materials using a helical screw mounted on a central shaft. They are controlled by servo motors and come in two types: volumetric and gravimetric. They are commonly used in industries requiring constant and accurate control of feed rates. An auger feeder is a […]

What’s a hydrogen car?

What’s the use of parallel capacitors?

[ad_1] Capacitors in parallel increase total capacitance due to their tendency to form a single capacitor with combined plate area. Capacitance is determined by plate area and is increased in parallel configurations. This is useful in smoothing DC output voltages in power supplies. Groups of capacitors are placed in parallel in a circuit to raise […]

What’s a hydrogen car?

[ad_1] Hydrogen vehicles use hydrogen as fuel and do not produce carbon dioxide or greenhouse gas emissions, but are not considered truly “zero emission” as hydrogen is typically produced from fossil fuels.
