Gardeners connect the drip hose to a water source and lay them along a row of tomatoes or wind them in between plants. Water leaks slowly from the hose at a rate of about Â½ gallon a minute per 100 feet of hose. 1  Drip hoses work best when they lay flat.  Place hoses directly on top of the soil, not underneath it.
Project Fi. Project Fi is Google's long-rumored (and finally official) program to provide fast and easy cellular service directly to phones. It works by combining access to both T-Mobile and Sprint, with a SIM card that can actively switch between the two without any user intervention.oogle has announced Project Fi, a new program that aims to keep you connected, no matter what network you're on. Beginning as an early access program, Google is working with Sprint and T-Mobile to build Fi. The service is centered around three main areas of focus: high-quality connections,...
RNAi Overview. RNA interference (RNAi) is a relatively new technology that is revolutionizing the way that researchers study mammalian gene expression. RNAi has had significant impact on the ease, speed, and specificity with which the loss of gene function analysis can be done in mammalian cells and animal models.This is becoming the method of choice for researchers doing loss of function studies. brief history of RNA interference (RNAi). Figure 1. Evolution of RNAi. RNA Interference (RNAi) is one of the most important technological breakthroughs in modern biology, allowing us to directly observe the effects of the loss of function of specific genes in mammalian systems.
