The Formation of Freckles in Binary Alloys
This paper presents a synopsis of some recent work, still in progress, aimed at elucidating a quantitative explanation of the processes by which flow chimneys form when certain types of alloys are directionally solidified. If (for example) light fluid is released at the liquid-solid "mushy" (dendrite) zone, and cooling is from below, then the intermediate fluid flow undergoes convection through...
متن کاملAnti-Freckles Herbal Treatment in Iranian Traditional Medicine
BACKGROUND Freckles are numerous pigmented spots of the skin, mainly confined to the face, even arms and back. Although freckles are light-brown macules, most frequently observed in individuals with red or blond hair, they are common to Asian people too.

متن کاملIris Freckles a Potential Biomarker for Chronic Sun Damage.
Purpose To investigate the role of sunlight exposure in iris freckles formation. Methods We prospectively examined volunteers attending a skin cancer screening program conducted by ophthalmologists and dermatologists. Frequency and topographical variability of iris freckles were noted and associated with behavioral and dermatologic characteristics indicating high sun exposure. Results Six h...
متن کاملClinical Approaches of Retinal Diseases in Pregnancy
Pregnancy leads to significant changes in the body, which potentially affect the retina. Pregnancy can induce disease such as that seen in hypertensive retinopathy and choroidopathy. It can cause exudative retinal detachments in the HELLP syndrome (hemolysis, elevated liver enzymes, and low platelets), disseminated intravascular coagulation (DIC), and thrombotic thrombocytopenic purpura (TTP), ...
متن کاملFlexible Electrode Array for Retinal Stimulation
In this Work, ITO/PET (Indium Tin Oxide / Polyethylene Terephthalate) electrode structure which provides biocompatibility, mechanical stability and flexibility is fabricated. Flexible ITO/PET implantable electrode array for a retina has been developed. The electrode array is fabricated on a thin PET/ITO substrate and is encapsulated using, SU-8, an insulating material. PET substrate and SU-8 po...
