Pretzels are crisp, brittle, and salted baked snack foods made of flour dough. These are available in various shapes and have shiny outer surfaces. Raw materials that are used to produce pretzels are flour, yeast, leavening agents, and shortenings. Different varieties of pretzels are available in the market in terms of shape and flavor. Companies sell pretzels as on- the-go snacks in packages, and some sell freshly made pretzels at foodservice outlets. The modern production process of pretzels is completely automated. It involves multiple steps, such as mixing the dough, forming pretzels, dipping, and salting, cooking, and packaging. These steps vary depending on the type of pretzel.

Process automation and instrumentation solutions are used for controlling the manufacturing process or control process in production without continuous human intervention. Process instrumentation is used for measuring process variables such as temperature, fluid, and others within industrial premises. Automation control systems include MES, DCS, PLC, and SCADA. Process instrumentation includes transmitters, control valves, and analyzers.

Professional lighting refers to the application of lighting techniques and fixtures to create optimal lighting conditions in various commercial and industrial spaces, including offices, retail stores, hospitality venues, healthcare facilities, sports arenas, and outdoor environments. It is designed to meet specific requirements, such as enhancing visibility, creating ambiance, highlighting architectural features, or promoting productivity and well-being. It incorporates lighting, control systems, and advanced technologies to provide efficient and customizable lighting solutions.

A projector is an optical device that projects an image or a series of moving images onto a surface, typically a projection screen. Lasers are used in some modern types of projectors to project the image directly. Instead of using an external projection screen, a virtual retinal display or retinal projector projects an image directly onto the retina. Video projectors are the most common type of projector used at present.

A pupillometer is a medical device used to measure and assess the size, shape, and reactivity of the pupils in the eyes.

A RF signal generator is an electronic device used to generate waveforms and electronic signals. RF signal generators produce continuous wave tones, which are used for designing, testing, troubleshooting, and repairing electronic devices and components. The capacity of RF signal generators ranges from a few kHz to 40 GHz.

Based on type, the global carbon black market is segmented into acetylene black, channel black, furnace black, thermal black, and others

A stool test can reveal the presence of blood or other gastrointestinal abnormalities such as colon or gastric cancer, inflammatory bowel disease, hemorrhoids, anal fissures, or infections. Microscopic inspection and chemical, immunologic, and microbiologic testing are all part of the stool analysis process. Leukocytes, lipids, sugars (reducing substances), pancreatic enzymes, alpha-1 antitrypsin, calprotectin, occult blood, and infectious causes (bacteria, viruses, and parasites) can all be detected in stool samples.

Surface-mount technology (SMT) is a method where the electrical components are fitted directly onto the surface of a printed circuit board (PCB). An electrical component mounted in such a manner is known as a surface-mount device (SMD).

Thermochromic paints are permanent change inks that are high temperature activated, permanent change pigment used for quality purposes in manufacturing processes such as metalworking, annealing, welding, and riveting for quality purposes where color former and color developer are intimately mixed. It has several practical uses, such as alerting someone to a potentially hot surface using thermochromic paint, which is not only extremely practical but helps to avoid serious injuries. The ability of thermochromic paints to make instantly aware of the temperature is extremely useful. It can also be used as an option to use special paints on road signs to alert drivers to specific temperatures such as freezing.
