This paper focuses on aerodynamic analysis over a 3D cambered wing with dimple-like surface modification. Application of the golf ball dimples airfoils is predicted to be good alternative for drag reduction. A allows smooth and controlled flight. Models wings based NACA 2412 airfoil were created investigate dimple effect. comparative study carried out between models inward outward at 50% chord ...

Background: Sacral pit is a shallow or deep dimple in the lower sacral region, with a reported prevalence of 3-5% among newborns. The aim of the present study was to investigate spinal cord abnormalities in newborns with sacral pit via ultrasound examinations. Methods: In this descriptive study, 3071 infants born at 34-42 weeks of gestation were studied in hospitals affiliated to Islamic Azad U...

BACKGROUND Becker nevus is a nevoid melanosis, referred to as Becker nevus syndrome when it is associated with other anomalies. Our objectives were to report the occurrence of a Becker nevus with an underlying desmoid soft-tissue tumor; to review Mayo Clinic's experience with Becker nevi, concentrating on Becker nevi associated with bone, vascular, neural, and other soft-tissue abnormalities; t...

A change in the shape of a charged surface of liquid hydrogen and helium — the formation of a solitary wave ~a positively charged hump for hydrogen and a negatively charged dimple for helium! – is observed in an electric field exceeding a critical value under conditions of total compensation of the applied field by the surface charge. © 1997 American Institute of Physics. @S0021-3640~97!01107-9#

US Patent 6,284,563 (Joseph Fjelstad) describes a method of making compliant microelectronic assemblies. This technique introduces a compliant layer (140) with a number of concave areas on top of a microelectronic element. Conductive flexible bond ribbons (175) are plated in these concave areas and extend to the periphery of the device. Electrical contacts can be formed with precision by placin...
