In a review evaluating 21 studies from 1999 to 2009 (18 studies therein from 2007 to 2009), BEV and PHEV consumed a mean of 17.5 kWh/100 km [29].
Although numerous studies have expounded on depletion of the Ogallala aquifer, very few researchers have studied groundwater quality therein which relates to the 'usability' of available groundwater resources.
Our findings show an increase of mRNA abundance of all genes therein studied upon HS treatment only when seedlings were grown in the presence of nitrate.
Using this technique, Rajaram (1980, 1983) (for more details, see references therein) studied the common and anomalous features of equatorial geomagnetic variations and also determined the latitude of the Sq focus.
The evolution of the mean grain size (i.e. size may be radius, area or volume) during grain growth has been extensively studied [[21 23], and references therein].
Remark 3.4 Several authors (see, e.g., [8, 31] and references therein) have studied the following problem: Let C be a closed convex nonempty subset of a real Hilbert space H with inner product 〈 ⋅, ⋅ 〉 and norm ∥ ⋅ ∥.
It follows that if a map P is a retraction, then (Py = y) for all y in the range of P. For nonself-nonexpansive mappings, some authors (see [3, 4] and the references therein) have studied the strong and weak convergence theorems in Hilbert spaces or uniformly convex Banach spaces.
Recently, several authors (see [6, 11 14] and the references therein) have studied the existence of nontrivial or positive solutions for second-order three-point boundary value problem of the type { u ″ = f ( t, u, u ′ ), u ′ ( 0 ) = 0, u ( 1 ) = a u.
While there are plenty of results on the existence of periodic solutions for the p-Laplacian equation (see [1 10] and references therein), studying delay Liénard equations with a variable coefficient in front of the nonlinear term is relatively uncommon.
