Pull-out experiments were performed on three carbon fiber-reinforced polymer (CFRP) ground anchors simulating their applications in different rock types which provided different confinement levels. The CFRP tendons comprised, on the ground side, a prefabricated conical anchor body of high-strength grout in which two CFRP straps were embedded. The anchors reached an average load-bearing capacity...

This study analyzes how teens represent themselves through their profile photographs on a popular nonymous chat site. Using visual content analysis methods, we analyzed 400 profile photographs, controlling for the self-reported gender and the apparent race of the photographic subject. The analysis finds significant differences in gaze, posture, dress, and distance from the camera according to g...

cGMP regulates vascular smooth muscle tone and arterial wall response to proliferative signals. We determined plasma cGMP and carotid artery intima-media thickness (IMT) and diameter in 84 asymptomatic men submitted to investigation of their cardiovascular risk profiles. Plasma cGMP was positively associated with IMT (P<0.01) and diameter (P<0.05), independently of coexisting risk factors. Thes...

Modeling and predicting retweeting dynamics in social media has important implications to an array of applications. Existing models either fail to model the triggering effect of retweeting dynamics, e.g., the model based on reinforced Poisson process, or are hard to be trained using only the retweeting dynamics of individual tweet, e.g., the model based on self-exciting Hawkes process. In this ...

1.1 Overview One of the interesting changes in the last twenty years as the developed economies became service economies is that the emphasis in marketing changed from transactions to relationships. This shift is still not fully comprehended by many business people, but it is radically reshaping the effective methods of doing business. In the twentieth century, mass marketing took over, thanks ...

It is investigated how figures of merits of nanocomposites are affected by structural and interaction length scales, Aside from macroscopic effects without characteristic lengths scales and atomic-scale quantum-mechanical interactions there are nanoscale interactions that reflect a competition between different energy contributions. We consider three systems, namely dielectric media, carbon-bla...

Pulmonary tuberculosis (TB) persists as a great public health problem in Korea. Increases in the overall age of the population and the rise of drug-resistant TB have reinforced the need for rapid diagnostic improvements and new modalities to detect TB and drug-resistant TB, as well as to improve TB control. Standard guidelines and recent advances for diagnosing pulmonary TB are summarized in th...

The fiber bundle model is one of the most important theoretical approaches to investigate the fracture and breakdown of disordered media extensively used both by the engineering and physics community. We present the basic construction of the model and provide a brief overview of recent results focusing mainly on the physics literature. We discuss the limitations of the model to describe the fai...

in this research the effect of randomly reinforced soil and soil cement with different percent of cement and fiber and different length of fiber was investigated. samples were prepared according to the maximum dry unit weight and optimum water content due to the corresponding compaction curves. compressive and tensile strength were conducted on samples for different curing times. regression equ...

Computer technology has mostly focused either on the isolated individual, or has treated the person as a clueless extra wandering in a computer-controlled environment. Researchers seem to have forgotten that people are social animals, and that the quality of their lives is defined by their roles in human organizations. Instead of inventing technology for the individual as an isolated entity, wh...
