Adding steel braces to reinforced concrete frames is a common way for seismic rehabilitation of these structures. Due to ease of installation and the possibility of creating openings in the braced bays, this method of rehabilitation has been more preferred than using shear walls. In this paper, three experimental specimens including a reinforced concrete frame, a reinforced concrete frame with ...

Vogt M, Hoppeler HH. Eccentric exercise: mechanisms and effects when used as training regime or training adjunct. J Appl Physiol 116: 1446–1454, 2014. First published February 6, 2014; doi:10.1152/japplphysiol.00146.2013.—The aim of the current review is to discuss applications and mechanism of eccentric exercise in training regimes of competitive sports. Eccentric muscle work is important in m...

Stars are generally formed in clusters. Prior to the the dispersal of small clusters, which occurs on the time scale of 10 8 yr, dynamical interaction between young stars may also affect the stability and dynamical evolution of their companion planetary systems. Through a series of numerical simulations, we show that distant stellar encounters generally do not strongly modify the compact and ne...

Diplonemid mitochondria are considered to have very eccentric structural genes. Coding regions of individual diplonemid mitochondrial genes are fragmented into small pieces and found on different circular DNAs. Short RNAs transcribed from each DNA molecule mature through a unique RNA maturation process involving assembly and three types of RNA editing (i.e., U insertion and A-to-I & C-to-U subs...

The current consensus in exercise physiology is that the repeated bout effect always appears after few eccentric exercise sessions. This is the first attempt to challenge this tenet, by exploiting specificity in muscle plasticity. More specifically, we examined whether the opposing adaptations in muscle induced after concentric and eccentric exercise can attenuate and/or remove the repeated bou...

This study investigated whether the specific motor control strategy reported for eccentric muscle actions is dependent on muscle mechanical behavior. Motor evoked potentials, Hoffman reflex (H-reflex), fascicle length, pennation angle, and fascicle velocity of soleus muscle were compared between isometric and two eccentric conditions. Ten volunteers performed maximal plantarflexion trials in is...

ABSTRACT We analyse how drag forces modify the orbits of objects moving through extended gaseous distributions. consider hydrodynamic (surface area) and dynamical friction (gravitational) drive evolution orbital eccentricity. While cause eccentric to become more circular, can eccentric. develop a semi-analytic model that accurately predicts these changes by comparing total work torque applied o...
