Mastopexy: Modification of periwinkle shell operation. Ten years of experience
Aesthetic Plastic Surgery, 1990Degrees I and II ptosis and atrophy of the female breast can definitively be corrected by the modified periwinkle shell operation. More problematic are the long-term results after correction of a degree III condition, especially when silastic prostheses for augmentation have been used.

Microgeographical shell variation in Littorina striata , a planktonic developing periwinkle
Marine Biology, 1997Littorina striata is a strictly Macaronesian, intertidal periwinkle with planktonic development. The species produces both nodulose and smooth shells, which co-occur at Ilheu de Vila Franca do Campo, a drowned crater situated about 1000 m off the south coast of Sao Miguel, Azores.

Effect of Detergent on Concrete prepared with Periwinkle shell as Coarse Aggregate
Materials Science Forum, 2021The use of the periwinkle shell in the production of lightweight concrete has been studied and accepted to be used for concrete works. Hard water containing detergent-like chemicals has been observed to be used in mixing locally produced concrete. This exploratory study is on the effect of water mixed with detergent in a concrete prepared with the ...

The Potential Use of Periwinkle Shell as Coarse Aggregate for Concrete
Advanced Materials Research, 2009The potential of periwinkle shell as coarse aggregate for concrete was studied in this paper. The properties of concrete made with periwinkle shell as coarse aggregate were examined. Test conducted on the concrete was compressive strength test. Prescribed mix designs of 1:1:2, 1:2:3, 1:4:6, 1:2:4 and 1:3:5 were used to produce concrete cubes used for

MECHANICAL PROPERTIES OF PALM KERNEL SHELL CONCRETE IN COMPARISON WITH PERIWINKLE SHELL CONCRETE
Malaysian Journal of Civil Engineering, 2018Comparative analysis of mechanical properties of palm kernel shell concrete with periwinkle shell concrete is presented in the paper. The binder and fine aggregate were Ordinary Portland cement and river sand, respectively, while potable water was used for mixing and curing. The constituent materials were batched by weight. Concrete mix ratio was 1:2:4
