Researchers at Purdue University have developed several new walnut varieties (Greatwoods) that reduce variation in growth rate and tree form. Greatwoods have higher growth rates, better timber quality, and a stronger resistance to disease than any clones currently available. Black walnuts are not th.....

BackgroundA common feature in photovoltaic (PV) systems is that their power output is unpredictable and unstable in nature (intermittent). Various storage technologies can smooth the stochastic power output levels but are neither cost-effective nor efficient. In addition, many PV systems are typical.....
