Silane treatment used to improve mechanical properties and swelling behaviour of polypropylene/coconut fiber (PP/CF) composites by creating more adherent bonding between CF filler and PP Matrix. 3-Aminopropyltriethoxysilane (3-APE) treated and untreated composites were prepared in formulation of 10 wt%, 20 wt%, 30 wt%, and 40 wt%. The mechanical testing indicates that composite with 10 wt% has the optimum value of tensile strength, and the 3-APE treated composites shows the tensile strength was increased. By increasing of filler loading, elastic modulus was increased while the elongation at brake was decreased. Meanwhile, the swelling test discerned that the increase of filler loading increased the water absorption of composites and the presence of 3-APE reduced the equilibrium water absorption percentage.

The aim of this study was to evaluate the effect of elastane material linear densities on lateral compression values (ankle and calf) in newly designed shape (V-shape) compression socks. For this purpose, three types of yarns: main yarn (MY), plating yarn (PY) and inlaid yarn (IY) were used. Each yarn contains elastane material as core with varying linear densities. Firstly, Machine adjustments were optimized to achieve special V-shaped compression socks according to fix leg size. All the yarns were installed simultaneously and evaluated for their impact on compression pressure value at different segments of leg. Total eighteen socks samples were developed and quantified for pressure exertion using MST MKIV, Salzmann pressure monitoring device. All samples were analyzed using ANOVA in MINTAB 16 software. Consequently, only two socks samples finalized acquiring pressure exertion values of 21 mmHg and 23 mmHg with graduation percentage of 76% and 74% simultaneously

Concrete filled steel tabular columns have gained immense importance in recent decades due to numerous structural benefits especially in developed countries like china, Japan, U.S.A, Britain. In this paper analytical equations are put to understand the mechanism of concrete filled tabular columns under axial loading. For this purpose a comparison between design codes Eurocode-4, and AISC-LRFD has been made in evaluating the axial compressive strength of concrete filled tabular columns. This study further presents a numerical investigation in to the behavior of concrete filled tabular columns using three dimensional nonlinear finite element software ABAQUS 6.13. The proposed finite element model is validated by comparing its results with those of the corresponding experimental specimens. The analytical results obtained are compared with the numerical results obtained from ABAQUS. Both square and circular concrete filled tabular columns having steel tubes of different geometries and infilled with different grades of concrete chosen from the literature are analyzed and the predicted axial strength obtained from different codes and by finite element analysis are compared. In this study 10rectangular specimens and 4 circular are analyzed.
