Sun protective behaviour and sunburn prevalence in primary and secondary schoolchildren in Western Switzerland [PDF]

open access: yes, 2015
Background: Switzerland has one of the highest incidence of cutaneous malignant melanoma, a potentially preventable cancer since its main risk factor, exposure to ultraviolet (UV) radiation, is amenable to behavioural changes.

Clean‐Limit 2D Superconductivity in a Thick Exfoliated Kagome Film

open access: yesAdvanced Functional Materials, EarlyView.
This study reports clean‐limit 2D superconductivity in a thick kagome system, analogous to the 3D case. It observes a drop in superfluid stiffness near the superconducting transition and a cusp‐like feature in the angular dependence of the upper critical field.

Fermi Surface Nesting and Anomalous Hall Effect in Magnetically Frustrated Mn2PdIn

open access: yesAdvanced Functional Materials, EarlyView.
Mn2PdIn, a frustrated inverse Heusler alloy, showing electronic‐structure driven anomalous Hall effect with Weyl crossings, Fermi‐surface nesting and near‐zero magnetization ideal for low‐magnetization spintronics. Abstract Noncollinear magnets with near‐zero net magnetization and nontrivial bulk electronic topology hold significant promise for ...

Cool Kitchen: Processing Starch and Eggshell Powder into Sustainable Coatings for Passive Daytime Cooling

open access: yesAdvanced Functional Materials, EarlyView.
A food‐grade cooling composite made from starch and recycled eggshell powder offers a scalable, ultra‐low‐cost solution for passive daytime radiative cooling. Easily prepared using basic kitchen tools, this material empowers communities, even in areas with limited infrastructure, to stay cooler during worsening summer heat waves.

Sun Protection Policy in Elementary Schools in Hawaii

open access: yesPreventing Chronic Disease, 2004
Introduction Childhood sun exposure is a major risk factor for skin cancer, the most common form of cancer in the United States. Schools in locations that receive high amounts of ultraviolet radiation have been identified as important sites for reducing ...

Penentuan Nilai Spf (Sun Protecting Factor) Ekstrak N-heksan Etanol (1:1) Dari Rice Bran (Oryza Sativa) Secara in Vitro Dengan Metode Spektrofotometri Uv-vis [PDF]

open access: yes, 2014
Sunlight is an energy source for the survival of living on earth, but the overexposure on the skin provides the degree of damage depends on the frequency and duration of sunlight exposure on the skin.
