How can you turn desert into farmland?

...out of the soils. Mweetwa and her team are isolating bacteria that thrive in legume root systems, where they live alongside and work together with a type of fungus that expands plant roots’ water and nutrient uptake. “We have already done the reintroduction to see if what we have isolated can reconnect with the beans, and those results are looking pretty good at the...

...out their hands, and piteously crying to him for relief." Saint Patrick prepares for his mission in Ireland "Some think he had travelled into Gaul before he undertook his mission, and we find that, whilst he preached in Ireland, he had a great desire to visit his brethren in Gaul, and to see those whom he calls the saints of God, having been formerly acquainted with them....

Introduction to quantum computing

...out computations; i.e. they are binary based. The complexity of tasks that any computer can complete is limited by the available time and computing resources. There are two routes to increasing the power of classical computing: one is to improve the hardware, which means increasing the size of the memory, the number of gates on a processor chip, or improving the speed of...

Cell signalling

...out the cellular response(s) of the signalling pathway). In the yeast, signal transduction to mating factor ultimately stops the target cell proliferating, and induces morphological changes which result in the formation of protrusions towards the cell that releases the mating factor (Figure 1b). The morphological changes are a response to the signal. The two cells can...

...out amplifiers or regenerators. Optical fibre has completely superseded copper wires as the primary medium for cabled transmission over long distances. As demand for capacity has risen, fibre is now being used even in LANs and the access network. An understanding of optical-fibre communications is therefore very important for anyone with an interest in digital...

Fundamentals of cost accounting and environmental management accounting

...out the marginal cost of a unit of output at any level of activity within the so-called relevant cost range. When we cannot accurately predict the future level of activity (which happens often), this classification of costs gives us a powerful management tool for evaluating results under different levels of activity. Variable costs are directly proportional to the level...
