I analyze an economy in which firms can undertake both laborand capital-augmenting technological improvements. In the long run, the economy resembles the standard growth model with purely labor-augmenting technical change, and the share of labor in GDP is constant. Along the transition path, however, there is capital-augmenting technical change and factor shares change. Tax policy and changes i...

Summary answer Sperm and can be used as a predictive marker for IUI outcome. What is known already Oxidative stress resulting from excessive production of (ROS) profoundly subsequent functional integrity. Diagnostics to measure semen oxidative have been added 6th ed...

An alkaline primary Mg-air battery made from a porous Mg thin film displayed superior discharge performances, including a flat discharge plateau, a high open-circuit voltage of 1.41 V and a large discharge capacity of 821 mAh g(-1), suggesting that the electrochemical performances of Mg-air batteries can be improved by controlling the Mg anode morphology.
