Frictional lichenoid dermatitis is a skin condition characterized by lichenified plaques and papules resulting from repetitive friction or rubbing against the skin. It commonly affects areas prone to friction, such as the inner thighs, neck, and under breasts. Histologically, it shows epidermal hyperplasia, orthokeratosis, and acanthosis. Management involves emollients, lubricants, topical steroids, and oral antipruritics….

Channel associated signaling is a communication method used in telecommunication systems where signaling information is transmitted over the same channel as user traffic. It classifies into in-band (signaling on traffic channel) and out-of-band (dedicated signaling channel). Related methods include common channel (shared signaling) and dedicated signaling (exclusive signaling channel). Channel concepts involve forward and reverse…

The red-flanked duiker (Cephalophus rufilatus) is a small, ruminant mammal native to West and Central Africa. It belongs to the family Bovidae and is closely related to other duiker species. Its distinctive white shoulder stripe and pointed horns in males differentiate it from other duikers. Found in dense forests and woodlands, the red-flanked duiker is…

Chlorhexidine teeth staining occurs due to the prolonged use of chlorhexidine gluconate (CHX), an antimicrobial agent typically found in mouthwashes and gels. This extrinsic staining is caused by CHX binding to dental plaque and forming complexes with tannins and other chromogenic agents. While CHX effectively reduces plaque and gingivitis, it can also lead to brown…

** Introduction:** UPLC-MS/MS combines ultra-performance liquid chromatography (UPLC) and tandem mass spectrometry (MS/MS), enhancing sensitivity, selectivity, resolution, and structural elucidation. Concepts:** UPLC separates analytes using high pressure and smaller particles, while MS/MS fragments ions for structural information. Ionization converts analytes into ions, and mass analyzers measure their mass-to-charge ratio. Applications:** UPLC-MS/MS enables qualitative and quantitative…

Stress skin panels are lightweight sandwich structures used for high-strength and flexible constructions. Composed of a thin outer skin bonded to a framework (substructure), they provide excellent strength-to-weight ratios. The skin, bonded using adhesives or welds, transfers loads to the framework, which resists bending and shear forces. Stress skin panels offer advantages such as low…
