energy as an important production factor has significant effects on economic growth. identifying the relationship between energy and economic growth can help to improve governmental energy policies. applying ardl and ecm methods, this paper examines the longrun and shortrun causality relationships between (1) energy consumption and economic growth and (2) energy consumption and employment in va...

Abstract One of the applications composites is in manufacturing tubes, which are widely used industries such as petroleum, petrochemical, and aerospace. Composite tubes made thermoset resin base material reinforced by fibers, having a solid, lightweight, corrosion-resistant structure, great replacement for metal concrete tubes. In this research, composite with various resins material, Swancor90...

Determination of the effective elastic properties unidirectional short fiber reinforced composites (SFRCs) is a key fundamental requirement which usually estimated by mean-field homogenization (MFH) methods. Available classical MFH methods only account for volume fraction and aspect ratio fibers do not consider physical cylindrical geometry fibers. Moreover, MFHs are designed predicting SFRCs w...

Abstract To reveal the effects of microstructure characteristics including fiber shape, void, distribution pattern, and interphase on transverse moisture diffusivities unidirectional composites, steady analysis method based Fick’s law is adopted. The predicted numerical results are compared with from analytical models to demonstrate accuracy. From simulation results, it found that increase in o...

1. The primary goal of this study was to characterize the information about single-joint forelimb movements supplied to intermediate cerebellar cortex by mossy fibers. Discharge of mossy fibers and Golgi cells was studied while monkeys operated six devices that required movements about specific joints. Additional control experiments in anesthetized cats and monkeys established criteria for iden...

Synthetic dental fiber tape for reinforcement (FRC) restoration is relatively costly and its availability still limited in Indonesia, so natural fibers have been used as an alternative material. The aim of this study was to assess the effect impregnation various toward flexural strength hardness FRC. materials were Bombyx mori silk (Indonesia), polyethylene (Construct Kerr, USA), Quartz (Quartz...

large intercoronary communications in the absence of obstructive coronary artery disease constitute a very rare coronary artery anomaly in which there is a readily visible connection between the 2 coronary arteries with a unidirectional or bidirectional blood flow; consequently, this anomaly may be misinterpreted as a functioning collateral vessel, indicative of an unrecognized proximal coronar...
