The Soil supports a range of microorganisms and is one of the most complex microbial habitats, allowing the fungi to sustain their entire life cycle. Soil is a cosmopolitan habitat for majority of microbial population that can be explored to find out more specific fungal flora.1 The soils rich in keratinous material were found to more conducive for keratinophilic fungi2−11 where this group of f...

This paper presents the results of an experimental program conducted for evaluating the performance of corrosion damaged HSC beams strengthened with GFRP laminates. Five Beam specimens of size 150x250x3000 mm were caste and tested for the present investigation. One beam specimen was neither corroded nor strengthened to serve as reference. Two beams were corroded to serve as corroded control. A ...

Glass fiber-reinforced polymer- (GFRP-) packaged optical fiber (OF) sensors are considered a promising engineering-suitable sensor for structural health monitoring. To date, some critical characteristics of the GFRP-packaged OF (GFRP-OF) have not yet been thoroughly studied. This study aimed to systematically characterize properties GFRP-OF sensors. Firstly, we proposed dimension optimization m...

Glass Fiber Reinforced Plastic composites have an increased application in recent days, due to its enhanced structural, mechanical and thermal properties. The heterogeneous nature of this kind of materials makes complications during machining operations. Drilling of holes in GFRP becomes almost unavoidable in fabrication. However, drilling is a common machining practice for assembly of componen...

This paper deals with the study of machinability of GFRP composite tubes of different fiber orientation angle vary from 30 to 90. Machining studies were carried out on an all geared lathe using three different cutting tools: namely Carbide (K-20), Cubic Boron Nitride (CBN) and Poly-Crystalline Diamond (PCD). Experiments were conducted based on the established Taguchi’s Design of Experiments (DO...

This paper aims at demonstrating the feasibility of Glass Fiber Reinforced Polymer (GFRP) systems for low-profile bypass roadways, in particular, sandwich panels comprised of GFRP facings and a Fiber Reinforced Foam (FRF) core. With the purpose of investigating the performance of the sandwich construction, an experimental program, including static and dynamic fatigue tests, was performed. The s...

Abstract In this study, the effect of nailing angle on pull-out capacity nails in soil slopes was investigated using finite difference method with help FLAC 3D software. Initially, geometric model created at three different angles excavation slope (45°, 63°, and 80°). Considering Mohr–Coulomb behavioral applying physical parameters order to nail system, five rows angles, relative horizon, which...
