Since recently, there are numerous results in studying boundary value problems for ordinary differential equations in the presence of a lower solution α and an upper solution β with (alphaleqbeta).
Pursuing the most productive method of directed differentiation has been the subject of numerous studies, resulting in the development of many effective protocols.
Their colour changes have been the focus of numerous studies, resulting in a description of rapid changes associated with courtship displays [21] [23] and stress [19], [24], [25].
Zn exposures, likewise have impacted reproduction in numerous studies, resulting in reduced fecundity and population growth rate in Valvata piscinalis [10], reduced fecundity in Helix aspersa [6], and, as an effluent containing Zn, Cd, and Fe, mortality and reduced egg laying in Lymnaea palustris [9].
That can be confirmed by numerous conclusions resulting from other studies [ 15, 16, 18].
Furthermore, numerous results from time-series studies have shown an association between mortality and particulate air pollution, and the results observed were similar (Filleul et al. 2001; Goldberg et al. 2001; Samet et al. 2000).
As a result, numerous studies have discussed the control and acceleration of osteogenic differentiation of hMSCs on graphene based hybrid nanomaterials.
Similar to our results, numerous studies have found strong and very strong positive correlations between pain intensity and neck disability with respect to craniofacial disability [41, 43, 44].
Aiming to promptly process the massive fault data and automatically provide accurate diagnosis results, numerous studies have been conducted on intelligent fault diagnosis of rotating machinery.
As a result, numerous studies have considered the power-line channel modeling method to accurately establish an effective PLC transmission model and select the best transmission frequency according to the frequency selectivity transmission characteristic [6 8].
