An Overview of the Applications of Periwinkle (Tympanotonus fuscatus) Shells

open access: yesCurrent Journal of Applied Science and Technology, 2021
The waste generated by the periwinkle (Tympanotonus fuscatus) shell cannot be undermined. In coastal communities worldwide, periwinkle is a major source of proteins and other vital minerals in most delicacies. The shells of these aquatic species, notable for their nutrient provision, contribute to environmental degradation because of the indiscriminate

Shoreline oiling effects and recovery of salt marsh macroinvertebrates from the Deepwater Horizon Oil Spill [PDF]

open access: yesPeerJ, 2017
Salt marshes in northern Barataria Bay, Louisiana, USA were oiled, sometimes heavily, in the aftermath of the Deepwater Horizon oil spill. Previous studies indicate that fiddler crabs (in the genus Uca) and the salt marsh periwinkle (Littoraria irrorata)

Investigating the Performance of Palm Kernel Shells and Periwinkle Shells as Coarse Aggregates in Concrete [PDF]

open access: yesLAUTECH Journal of Civil and Environmental Studies, 2020
Excessive usage of materials is causing fast depletion of natural stone deposit. This study therefore investigates the performance of palm kernel shells (PKS) and periwinkle shells (PS) as alternatives coarse aggregates in concrete. Forty cubes and 40 cylinders each were produced with PKS and PS as replacement materials for granite.

Thermal, structural and acetylation behavior of snail and periwinkle shells chitin [PDF]

open access: yesProgress in Biomaterials, 2017
This article reports a successful removal of CaCO3 from snail and periwinkle shells for the purpose of producing high quality chitin for possible application as bio-fillers in bone fixation materials. Experiment was designed with varying concentrations of acid and alkali for demineralization, deproteinization and deacetylation of the samples.

Characterizations of some discarded shells particles polymer-based composites for ceilings and particles board applications

open access: yesRecent Advances in Natural Sciences, 2023
Sea-shells, periwinkle-shells, and snail-shells were pulverized into 35.5 µm particle sizes. Using a two-roll Rheomixer with a rotor speed of 60 rpm for 10 minutes, the particles were thoroughly mixed with the binders in ratio 2:1 and placed in the ...

Potentials of waste seashells as additives in drilling muds and in oil well cements

open access: yesCleaner Engineering and Technology, 2020
Additives to drilling fluids and oil well cements play a significant role during wellbore drilling operations. These additives (such as carboxymethyl cellulose and starch) are often expensive and most times degrade at high temperature conditions ...
