The global market for tires is ever-growing, and partially replacing sand with crumb rubber (CR) as fine aggregates in concrete could reduce environmental pollution. However, the main barrier to complete usage of recycled tire crumbs construction deterioration effect CR on mechanical properties cement-based composites. Therefore, this paper attempts improve fresh hardened mortar (CRM) by incorp...

Kenaf (Hibiscus cannabinus L.), an environmental friendly and economic fiber crop, has a certain tolerance to abiotic stresses. Identification of reliable reference genes for transcript normalization of stress responsive genes expression by quantitative real-time PCR (qRT-PCR) is important for exploring the molecular mechanisms of plants response to abiotic stresses. In this study, nine candida...

A sequential solvent extraction scheme was employed for the extraction of antioxidant compounds from kenaf (Hibiscus cannabinus L.) seeds. Yield of extracts varied widely among the solvents and was the highest for hexane extract (16.6% based on dry weight basis), while water extract exhibited the highest total phenolic content (18.78 mg GAE/g extract), total flavonoid content (2.49 mg RE/g ext...

Different levels of NPK fertilizer were used to improve the growth, yield, and fiber morphology two kenaf varieties. Therefore, a field experiment was conducted in summer season 2021 at Grdarasha Field, College Agricultural Engineering Sciences, Salahaddin University-Erbil. The results revealed that adding rate 100 kg/ha caused improved growth yield characteristics includes; plant height, stem ...

Abstract In this research, the hybrid natural fiber composite specimens were fabricated with a 64 wt% epoxy resin matrix, 20 coir fiber, and 16 of various fibers by hand-layup method. The influences (Coir, Jute, Flax, Cotton, Human Hair, Sisal, Kenaf, Calotropis) on mechanical characteristics (tensile, flexural, impact strengths) drilling properties (delamination factor ovality) Coir-fiber base...

The purpose of the current study was to determine the effect of root-knot nematode infection on the growth of kenaf. Seeds of sixteen (16) varieties of kenaf, comprising of eight from Australia, three local and five accessions from Bangladesh were planted under controlled condition and inoculated with four level of 0, 1000, 5000 and 10000 RKN eggs per plant. The growth parameters of height, sta...

The efficiency and dynamics of simultaneous kenaf biomass decomposition by basidiomycetous fungi and actinobacteria were investigated. After 8weeks of incubation, up to 34wt.% of the kenaf biomass was degraded, with the combination of fungi and bacteria being the most efficient. Lignin decomposition accounted for ∼20% of the observed biomass reduction, regardless of the culture used. The remain...
