In the analytical expression of the PEMFC polarization curve, Eq. (16) , the independent variables are the current density, the temperature and the pressure, while the dependent variable is the voltage. Moreover there are a few constants, that usually are called parameters, and some of these are often unknown.
In particularly cold areas, Trachelospermum jasminoides is best grown in patio containers of loam based compost, such as John Innes No.2, that can be moved to a protected position over winter. Provide the twining stems with an appropriate support such as trellis, wires or a free standing climbing frame.row star jasmine plants in frost-free conditions until large enough to plant outdoors. When they are well grown, plant Trachelospermum jasminoides in fertile, well drained soil in sun or semi-shade. Choose a sheltered position that is protected from cold winter winds.
Another alternative: About two months before your last frost date in spring, take cuttings from geranium plants that you brought indoors and treated as houseplants.. 3. Let the geraniums go dormant and store in a cellar. This is the best method if you have lots of geraniums and nowhere to grow them as houseplants.iew Caption. Geraniums (actually Pelargoniums, botanically) are more expensive than most annual plants we grow in our yards. So, when cooler weather reminds us that fall is here and winter not too far behind, it's natural not to want to lose them all to frost -- especially if we plan to buy and plant more next year.
