get_powers_j: scaled powers for abj model
In Echinophoria/DEB: What the Package Does (One Line, Title Case)

Description Usage Arguments Value Note Author(s) References See Also Examples

This function calculates scaled powers assimilation, mobilisation, somatic maintenance, maturity maintenance, growth, reproduction and dissipation as function of length and scaled reserves

1	get_powers_j(p, L, e, s_M)

`p`	A named list resulting from the importing of DEB parameters using the function `get_DEB_pars`. Alternatively a vector containing the DEB parameters (g, k, v_Hb, v_Hj and v_Hp (optional)) in the same order. For symbol meaning check code and documentation of `get_DEB_pars`
`L`	Structural length of the organism for which the powers are being calculated (it can be a vector)
`e`	Scaled reserves at which the variables are to be calculated (see Kooijman 2010 for a definition of e). It is a value between 0 and 1.
`s_M`	Acceleration factor for abj model.

This function return a vector/matrix containing s scaled powers p_A, p_C, p_S, p_J, p_G, p_R, p_D They can be unscaled by * L_m^2 p_Am p_A = assimilation power; p_C = mobilisation power; p_S = somatic manteinance power; p_J = maturity mainenance power; p_G = growth power; p_R = reproduction power; p_D = dissipation power;

Scaled values obtained here can be unscaled for further use. See examples. For further info on temperature corrections see Kooijman 2010 and t_corr
