PREDICTION OF COMPRESSIVE STRENGTH OF CEMENT BLENDED FLY ASH-PERIWINKLE SHELL ASH SANDCRETE BLOCKS

, 2017
This study centred on the development of a mathematical model for the prediction of the compressive strength of cement blended Fly Ash-Periwinkle shell ash sandcrete blocks using Scheffe’s simplex lattice. A total of ninety (90) fly ash-PSA solid sandcrete blocks of dimensions 450 x 125 x 225 mm were cast, consisting of three (3) blocks per mix ratio ...

Of Clams and Clades: Genetic Diversity and Connectivity of Small Giant Clams (Tridacna maxima) in the Southern Pacific Ocean

Ecology and Evolution, Volume 14, Issue 10, October 2024.
We sequenced the cytochrome oxidase 1 (CO1) gene in small giant clams (Tridacna maxima) in Australia's Coral Sea Marine Park and Cook Islands to assess the genetic diversity and connectivity of these populations. Both regions had very high haplotype diversities but differed in their population structures, with no structure detected within the Coral Sea

β‐Chitin and chitosan from waste shells of edible mollusks as a functional ingredient

Food Frontiers, Volume 5, Issue 1, Page 46-72, January 2024.
This review explores the edible mollusk shell waste sources and its suitable extraction techniques, characterizations, and functional properties of β‐chitin and chitosan. Further, the genetic pathway of synthesizing mollusk chitin and chitosan was discussed.

Trait compensation in marine gastropods: shell shape, avoidance behavior, and susceptibility to predation [PDF]

, 2004
Many organisms have evolved morphological and behavioral traits that reduce their susceptibility to predation. However, few studies have explicitly investigated the relationships between defensive traits and susceptibility. Here we demonstrate a negative

Understanding the Factors Influencing the Properties of Biomass‐Derived Porous Carbon and Their Impacts on Electrical Double‐Layer Capacitor Electrodes: A Comprehensive Review

Journal of Renewable Energy, Volume 2024, Issue 1, 2024.
The use of biomass as carbon precursors has been extensively investigated, with a particular emphasis on examining the properties of derived porous carbon and its application in electrical double‐layer capacitors (EDLCs). Biomass‐derived porous carbon‐based electrodes have shown promising properties that can improve the efficiency of EDLCs.

Assessing the Mechanical Performance of Ternary Blended Cement Concrete Incorporating Periwinkle Shell and Bamboo Leaf Ashes [PDF]

, 2013
The study investigates the mechanical properties of concrete incorporating Periwinkle Shell Ash (PSA) and Bamboo Leaf Ash (BLA) as cementitious binders. Concrete cube (100mm) prepared from a standardized prescribed mix of 1:2:4, batch by volume was taken

Cymbopogon nardus Leaf Ash as an Alternative Material for Enhancing Concrete Strength

Advances in Civil Engineering, Volume 2024, Issue 1, 2024.
Numerous waste materials containing calcium and silica have been adopted as partial cement substitutes. This practice is intended to reduce the environmental impact of cement production, specifically in terms of carbon dioxide (CO2) emissions. However, plantation waste, specifically waste from Cymbopogon nardus leaf, has not been completely exploited ...

CHARACTERIZATION OF PERIWINKLE SHELL ASH REINFORCED POLYMER COMPOSITE FOR AUTOMOTIVE APPLICATION

FUDMA JOURNAL OF SCIENCES
The Periwinkle shell (Tympanotonus fuscatus) is one of the most abundant wastes in the Calabar coastal region of  Nigeria and needs to be put into proper use. The great need to shift attention towards waste materials with good mechanical properties to replace some materials used in the Automobile industries for Automobile products is paramount.
