چکیده
Plantation softwood timber poles are associated with low natural durability, and it is also not clear what the effects of high humidity environment on long-term performance composite action integrity such a system. This paper presents durability study for proposed using (GFRP) glass fiber-reinforced polymer as confinement system wooden sourced from plantation timber. Radiata pine 6 m length were wrapped multiple layers 0°/90° woven roving biaxial E-glass fiber sheets through wet layup process confinement. The prepared GFRP then subjected to environmental conditions up 95 ± 2% relative 22 2 °C temperature period 30 months. Various lengths considered in this ranging 0% 70% span length. had 5.4 tested three-point bending test. Results showed that GFRP-softwood provided satisfactory did greatly affect improvement mechanical provided.

Long-Term Flexural Behaviors of GFRP Reinforced Concrete Beams Exposed to Accelerated Aging Exposure Conditions
This study investigates the impact of accelerated aging conditions on the long-term flexural behavior and ductility of reinforced concrete (RC) members with glass fiber-reinforced polymer (GFRP) bars (RC-GFRP specimen) and steel bars (RC-steel specimen). A total of thirty six specimens were designed with different amounts of reinforcement with three types of reinforcing bars (i.e., helically wr...
متن کاملChanges in biochemical and physiological responses of common carp, Cyprinus carpio L. after long-term exposure to Pb (II)
In this study, the chronic toxic effects of Pb (II) on common carp, Cyprius carpio were investigated using several biomarkers at different levels of biological functions for assessing changes in ecosystem quality. In a bioassay, common carp juveniles were individually exposed to different dose of heavy metal, Pb II (0, 0.45, 0.89, 1.34 mg.l-1) for 28 days. Morphological indices such as hepat...
متن کاملCytotoxicity of Subtoxic AgNP in Human Hepatoma Cell Line (HepG2) after Long-Term Exposure
Background: We aimed at evaluating the toxicity effects of low (subtoxic) concentrations of silver nanoparticles (AgNP, 5-10 nm) in human hepatoblastoma (HepG2) cell line after and during a period of about one month. Methods: XTT and MTT assays were used to draw a dose-response curve IC50 (half maximal inhibitory concentration) value of the AgNP on HepG2 cells was calculated to be 2.75-3.0 mg/l...
متن کاملHistomorphometrical changes of oviduct during the long-term exposure of breeder hens to extra thyroxine
In this research a 100 day long treatment period was considered to unmask the probable adverse effects of long-term induced hyperthyroidism on histomorphometrical attributes of the oviduct in broiler breeder hens. A total of seventy 47-week-old Cobb 500 breeder hens were randomly allotted to two treatment groups (5 replicates of 7 hens each). Thyroxine (T4) was orally administered to the hypert...
