Physicomechanical Properties of Rice Husk/Coco Peat Reinforced Acrylonitrile Butadiene Styrene Blend Composites.

Utilizing agro-waste material such as rice husk (RH) and coco peat (CP) reinforced with thermoplastic resin to produce low-cost green composites is a fascinating discovery. In this study, the effectiveness of these blended biocomposites was evaluated for their physical, mechanical, and thermal properties. Initially, the samples were fabricated by using a combination of melt blend internal mixer and injection molding techniques.

Mercerization Optimization of Bamboo (Bambusa vulgaris) Fiber-Reinforced Epoxy Composite Structures Using a Box-Behnken Design.

The objective of this research is to optimize the alkaline treatment variables, including sodium hydroxide (NaOH) concentration, soaking, and drying time, that influence the mechanical behavior of bamboo fiber-reinforced epoxy composites. In this study, a Box-Behnken design (BBD) of the response surface methodology (RSM) was employed to design an experiment to investigate the mercerization effect of bamboo fiber-reinforced epoxy composites. The evaluation of predicted tensile strength as a variable parameter of bamboo fiber (Bambusa vulgaris) reinforced epoxy composite structures was determined using analysis of variance (ANOVA) of the quadratic model.

Metal concentrations in American oyster Crassotrea virginica and adjacent sediments from harvestable and non-harvestable sites in the Southeastern USA.

Human population growth in coastal areas continues to threaten estuarine ecosystems and resources. Populations of Crassostrea virginica have declined across the USA due to water quality degradation, disease pressure, alteration of habitat, and other changes related to anthropogenic impacts. Metals that may be present in estuarine habitats can bioaccumulate in oysters, with potential consequences to the health of oysters and humans consumers.

Canine vector borne diseases of zoonotic concern in three dog shelters in Peninsular Malaysia: The importance of preventive measures.

This study investigated canine vector borne diseases (CVBDs) of zoonotic significance in three major shelters in Peninsular Malaysia in order to highlight the importance of shelter management in diseases prevention. Since crowded housing has the potential to bring vectors and infected dogs into close proximity, the prevalence of CVBDs infection is always higher in sheltered dogs in comparison to pet dogs. Serum was collected from 90 adult dogs (30 from each shelter) from three shelters in different regions of Peninsular Malaysia (Shelter A, B and C).
