An umbilical line is a catheter that is inserted into one of the two arteries or the vein of the umbilical cord. Generally the UAC/UVC (Umbilical Artery Catheter/Umbilical Vein Catheter) is used in Neonatal Intensive Care Units (NICU) as it provides quick access to the central circulation of premature infants .
The location of 'far-UVC' radiation (200-235 nm) in the electromagnetic spectrum. Far-UVC is a type of ultraviolet germicidal irradiation being studied and commercially developed for its combination of pathogen inactivation properties and reduced negative effects on human health when used within exposure guidelines.

A peripherally inserted central catheter (PICC or PICC line), also called a percutaneous indwelling central catheter or longline, [1] is a form of intravenous access that can be used for a prolonged period of time (e.g., for long chemotherapy regimens, extended antibiotic therapy, or total parenteral nutrition) or for administration of substances that should not be done peripherally (e.g ...
A low-pressure mercury-vapor discharge tube floods the inside of a biosafety cabinet with shortwave UV light when not in use, killing microbes on irradiated surfaces. Ultraviolet germicidal irradiation (UVGI) is a disinfection technique employing ultraviolet (UV) light, particularly UV-C (180–280 nm), to kill or inactivate microorganisms .
UVC may refer to: Science and technology ... Umbilical venous catheter or umbilical vein catheter, a type of umbilical line in neonatal medicine;
The root words photo, litho, and graphy all have Greek origins, with the meanings 'light', 'stone' and 'writing' respectively. As suggested by the name compounded from them, photolithography is a printing method (originally based on the use of limestone printing plates) in which light plays an essential role.
Side lobe levels of −20 dB or greater are usually not desirable in many applications. Attainment of a side lobe level smaller than −30 dB usually requires very careful design and construction. In most radar systems, for example, low side lobe ratios are very important to minimize false target indications through the side lobes.
The diagram shows that there are three quartet excited states: 4 T 2, 4 A 2, and 4 T 1 (P). From the diagram one can predict that there are three spin-allowed transitions. However, the spectrum of [Co(H 2 O) 6] 2+ does not show three distinct peaks that correspond to the three predicted excited states. Instead, the spectrum has a broad peak ...
