Enhancement of hydrophobicity and UV aging resistance of Poly (p-phenylene benzobisoxazole) fibers modified by fluorosilane and UV absorber. [PDF]
Sci Rep, 2019 Poly (p-phenylene benzobisoxazole) (PBO) fibers were functionalized by 3-Glycidoxypropyltrimethoxysilane (KH-560) and then coated with 1 H, 1 H, 2 H, 2H-Perfluorodecyltrimethoxysilane (HFTES) and UV absorber (UV-328) to improve hydrophobicity and UV ...

Optical and UV-Aging Properties of LDH-Modified Bitumen. [PDF]
Materials (Basel), 2015 Layered double hydroxides (LDHs) are an ultraviolet-light (UV) resistant material. In this study, LDHs were used to modify bitumen. The optical and UV aging properties of LDHs modified bitumen were investigated. Firstly, the thin films of bitumen, with and without LDHs, were prepared.

Synergistic interplay between UV and urban particulate matter exposure induces melanocyte senescence and contributes to human skin aging [PDF]
Scientific ReportsExtrinsic skin aging is driven by environmental factors, including ultraviolet (UV) radiation and air pollution. While melanocytes serve as key protectors against UV-induced damage, their role in aging, particularly through the process of senescence ...

Dermato-Endocrinology, 2012 Skin is a model of choice in studies on aging. Indeed, skin aging can be modulated by internal and external factors, reflecting its complexity. Two types of skin aging have been identified: intrinsic, mainly genetically determined and extrinsic-also called "photo-aging"-resulting on the impact of environmental stress and more precisely of UV rays ...

Dermato-Endocrinology, 2012 Age-associated skin lesions linked to UV radiation (UVR) include actinic keratosis, non-melanoma skin cancer-such as basal cell carcinoma and squamous cell carcinoma-lentigo senilis and lentigo maligna. Their incidence is increasing worldwide, mainly due to exaggerated UV exposure and to an aging population. Early diagnosis and therapy of pre-malignant

Kinematics and Ages of UV Ceti Stars [PDF]
International Astronomical Union Colloquium, 1995 AbstractThe kinematic properties of 93 UV Ceti stars of the solar neighborhood are studied, based on a list of flares within 25 pc of the Sun (π ≥ 0".04). With updated values for their distances, proper motions and radial velocities (Gliese & Jahreiss 1991) space velocity dispersions are calculated for these stars.
