This paper investigates the bond between high-strength concrete (HSC) and tensile lap-spliced basalt fiber-reinforced polymer (BFRP) bars. Ten large-scale BFRP-reinforced beams (300 × 450 3900 mm) were fabricated tested under four-point loading until failure. The parameters investigated included BFRP bar diameter (10, 12, 16 mm), splice length (400–1200 mm range), surface texture (sand-coated (...

A substantial fraction of barred galaxies host additional nuclear bars which tumble with pattern speeds exceeding those of the large-scale (primary) stellar bars. We have investigated the mechanism of formation and dynamical decoupling in such nested bars which include gaseous (secondary) nuclear bars within the full size galactic disks, hosting a double inner Lindblad resonance. Becoming incre...

The central kpc of barred galaxies exhibits a wealth of morphological information on different components with clear dynamical consequences. These include nuclear rings, spirals, bars, and more. We argue that this morphology is driven by large-scale stellar bars and analyze its consequences for gas dynamics and the distribution of star-forming regions. Specifically, we focus on gas flows in nes...

A new bariline fish, Barilius kamjongensis is decribed from Kamjong district, the Chindwin basin of Manipur, India. It can be distinguished its congeners in having a body with 2 pairs barbels, 16–19 predorsal scales, 12–15 bars, 40–43 perforated lateral line 7.5/2.5 transverse origin dorsal-fin closed to base caudal-fin, pectoral-fin shorter than head length, depth at 22.8–26.6 % SL, caudal ped...

Error bars commonly appear in figures in publications, but experimental biologists are often unsure how they should be used and interpreted. In this article we illustrate some basic features of error bars and explain how they can help communicate data and assist correct interpretation. Error bars may show confidence intervals, standard errors, standard deviations, or other quantities. Different...

This paper presents the results of an experimental study of the mechanical properties of FRP reinforcement bars, used as internal reinforcement in concrete structures, at elevated temperatures. Two types of FRP bars namely: carbon fibre reinforced polyester bars of 9.5mm diameter and glass fibre reinforced polyester bars of 9.5mm and 12.7 mm diameter were used in the study. For comparison, conv...

It is difficult to track, count and separate the bars moving at a high speed on production line for their overlap under occlusion. Therefore, it is necessary to establish a reliable, practical splitting mechanism for the adhered bars. This paper proposed a new solution to the problem of bars adhesion: the plane array camera was utilized to acquire the images of moving bars so as to recognize th...
