Mastopexy: Modification of periwinkle shell operation. Ten years of experience

Aesthetic Plastic Surgery, 1990
Degrees 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.

Effect of Detergent on Concrete prepared with Periwinkle shell as Coarse Aggregate

Materials Science Forum, 2021
The 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 ...

Investigation of coconut-periwinkle shell bio-composites for alternate thermal insulation application

Environmental Science and Pollution Research
Periwinkle and coconut shells are becoming increasingly popular as dielectric materials with thermal insulation properties. Natural sources of synthesis could provide a cheaper and more ecologically friendly alternative to chemically synthesizing such compounds as thermal insulators or fillers in polymer composites.

Microgeographical shell variation in Littorina striata , a planktonic developing periwinkle

Marine Biology, 1997
Littorina 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.

Efficacy of Periwinkle Shell Ash and Periwinkle Shell Powder in Bioremediation of Crude Oil-Polluted Mangrove Soil

International Journal of Advances in Engineering and Management
This study assessed the efficacy of periwinkle shell ash and periwinkle shell powder in bioremediation of crude oil-polluted mangrove soil. The 48-week experiment was conducted using a wooden microcosm (3.75 m2), subdivided into 18 cells (0.25 m), with each containing 20 kg of contaminated soil.

MECHANICAL PROPERTIES OF PALM KERNEL SHELL CONCRETE IN COMPARISON WITH PERIWINKLE SHELL CONCRETE

Malaysian Journal of Civil Engineering, 2018
Comparative 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

Evaluation of organic enhancer on the mechanical properties of periwinkle shells concrete

Journal of Engineering Innovations and Applications, 2022
The utilization of green materials in engineering applications has become a necessity due to the negative environmental and health consequences of most synthetic materials. Enhancement of periwinkle shell concrete through corn starch treatment was investigated in this study.
