Rice-maize systems of South Asia: current status, future prospects and research priorities for nutrient management Rice ( Oryza sativa L.) and maize ( Zey mays ) are grown in 3.5 million hectares (Mha) in Asia that includes 1.5Mha in South Asia. These crops are grown i... J Timsina,ML...
When beginning to explore the world of electricity and electronics, it is vital to start by understanding the basics of voltage, current, and resistance. These are the three basic building blocks required to manipulate and utilize electricity. At first, these concepts can be difficult to understand...

(V) across a resistor (R) in terms of the work done in moving a unit charge. State the relation between these two works and the work it charge through a cell connected across the resistor. Take the internal resistance of the cell as r. Hence, obtain expression for the current i in ...
Three resistors, 33 Omega, 48 Omega, and 110 Omega, are connected in series, and a 0.58-A current passes through them. What are (a) the equivalent resistance and (b) the potential difference across this equivalent resistance? T...
Helicoverpa armigera is a major pest on a wide range of crops in Europe, Africa, Asia and Australia. Insecticide treatments are currently indispensable for its control in almost all crops, which has resulted in insecticide resistance occuring in some situations. However, since information about insec...

After a resistance point has been overcome, it is not unusual to see sellers briefly test lower to the breakpoint to see if it holds. If it does, traders are likely to conclude that the break of resistance is valid and that the upside is in play. This is an example of a broken resi...
Those who have not yet decided which way to trade and remain on the sidelines As the price rises from a support level, the traders who are long are happy and may consider adding to their positions if the price drops back down to the same support level. The traders who are short in thi...
