Poisson distribution:How tensile properties of particulate polymer composites are enhanced in a Poisson-motivated Taguchi method

open access: yesEngineering and Applied Science Research, 2019
This paper examines how the Poisson distribution is being used to model thetensile properties of selected particulate reinforced polymer composites. While past studies have shown that the Taguchi method provides robust optimized composites forcost and ...

Long-Term Effects of an Invasive Shore Crab on Cape Cod, Massachusetts [PDF]

open access: yes, 2015
Invasive species can cause dramatic changes in the structure of intertidal communities. In some systems, however, abundance or impacts of invaders may peak 10–20 years after invasion and decline thereafter.

Development and distribution of the non-indigenous Pacific oyster (Crassostrea gigas) in the Dutch Wadden Sea [PDF]

open access: yes, 2009
Pacific oysters (Crassostrea gigas) were first observed in the Dutch Wadden Sea near Texel in 1983. The population increased slowly in the beginning but grew exponentially from the mid-1990s onwards, although now some stabilisation seems to be occurring.

PREPARATION AND INVESTIGATION OF THE PHOTOCATALYTIC PROPERTIES OF PERIWINKLE SHELL ASH FOR TARTRAZINE DECOLOURISATION [PDF]

open access: yesJournal of Mechanical Engineering and Sciences, 2014
The discharge of dye-containing effluents into the aquatic environment represents a source of aesthetic pollution with associated negative effects. Photocatalytic degradation has been identified as a suitable means of treating these effluents.

Isothermal and Batch Adsorption Studies of Malachite Green Oxalate Dye onto Activated Carbon from Snail Shell [PDF]

open access: yes, 2017
Adsorption efficiency, kinetic and thermodynamic studies of the adsorption of Malachite green oxalate onto activated carbon from snail shell was carried out. The cleaned Snail shell was carbonized at 400oC, crushed and sieved before it was activated with

Evaluation of the properties of lightweight concrete using periwinkle shells as a partial replacement for coarse aggregate

open access: yesJournal of Applied Sciences and Environmental Management, 2016
The properties of lightweight concrete, such as aggregate impact value, aggregate crushing value and compressive strength were assessed utilizing periwinkle shell (PWS) as partial replacement for coarse aggregate.

Optimization and Modeling of Cyanide Removal from Cassava Waste Water Using Calcined and Activated Adsorbent Mixtures of Oyster Shell and Periwinkle Shell Ash

open access: yesJournal of Engineering Research and Reports, 2023
Cyanide, a toxic compound found in cassava wastewater which on frequent basis is discharged to the environment poses danger to the ecosystem; this research work aims to curb this menace.

The impacts of biological invasions

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1255-1310, June 2026.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Cyanide adsorption from cassava wastewater onto calcined periwinkle shell

open access: yesJournal of Degraded and Mining Lands Management, 2019
Local cassava processing industries produce large quantities of wastewater containing cyanide which is toxic in nature with negative impacts on the environment when disposed without treatment.
