In this paper we present a new digital ultrasonic instrument for nondestructive inspection of rock bolts using guided waves. The Rock Bolt Tester (RBT) instrument applies long-range ultrasound to investigate bolt’s status, especially its grouting condition. RBT features an application tailored ultrasound probe that transmits high-energy, low frequency (below 100kHz) guided waves and is capable ...

Pada masa kini, penggunaan dron dalam pendidikan sebagai alat bantu mengajar telah semakin dikenali dan digunakan kalangan guru pensyarah bagi menarik minat pelajar aktiviti pembelajaran. Oleh yang demikian, objektif utama kajian ini adalah untuk menilai keberkesanan terhadap pencapaian topik reka bentuk elektronik. Reka Bentuk Elektronik merupakan salah satu sub pembelajaran diperkenalkan mata...

Papers published on the resource-based theory (RBT) have made clear its widespread application, heterogeneity, and usefulness as a strategic approach. This paper empirically analyzes the assumptions underlying the theory from an inductive perspective. The paper differs from previous works by identifying the main trends within the theory and by noting their diffusion among the leading management...

This paper introduces the resonant body transistor (RBT), a silicon-based dielectrically transduced nanoelectromechanical (NEM) resonator embedding a sense transistor directly into the resonator body. Combining the benefits of FET sensing with the frequency scaling capabilities and high quality factors (Q) of internal dielectrically transduced bar resonators, the resonant body transistor achiev...

Two established international reference preparations (IRP) for thromboplastins, i.e. RBT/90 (rabbit, plain) and rTF/95 (recombinant human, plain) have been calibrated against each other in a 7-centre exercise performed in 2000. The purpose of the study was to compare the calibration results with those of the original calibration study performed in 1995. The international sensitivity index (ISI)...

Forty four pigs with typical characteristics for false positive serolpgical reactions (FPSR) were examined for the presence of Yersinia enterocolitica O:9. The positive reactions were observed in rose bengal test (RBT, N = 23 sera), serum agglutination test (SAT, N = 16), complement fixation test (CFT, N = 9), indirect ELISA (i-ELISA, N= 11) in first, and in RBT (N = 14), SAT (N = 8), CFT (N = ...

Five serological assays were evaluated for the diagnosis of brucellosis in goats: the rose bengal test (RBT), complement fixation test (CFT), radial immunodiffusion (RID) with Brucella and Yersinia enterocolitica O:9 polysaccharides, counterimmunoelectrophoresis (CIEP) with cytosol, and enzyme-linked immunosorbent assay (ELISA) with polyclonal and protein G conjugates and smooth lipopolysacchar...

We consider the solution of sparse linear systems using direct methods via LU factorization. Unless the matrix is positive definite, numerical pivoting is usually needed to ensure stability, which is costly to implement especially in the sparse case. The Random Butterfly Transformations (RBT) technique provides an alternative to pivoting and is easily parallelizable. The RBT transforms the orig...

BACKGROUND This paper reports on the feasibility and initial efficacy of a culturally sensitive, comprehensive women-centered substance use intervention for women who inject drugs in Georgia in terms of the primary and secondary sex risk outcomes. The hypothesis under examination was that, relative to case management participants, participants in a culturally sensitive, comprehensive women-spec...

Introgressive hybridization is a common feature of many zones of contact between divergent lineages of fishes. This is particularly common when taxa that are normally allopatric come into artificial (human-induced) secondary contact. We examined 18 native populations of westslope cutthroat trout (Oncorhynchus clarki lewisi, WCT) to determine the extent of introgressive hybridization with introd...
