The life stages of seed germination and seedling establishment play a vital role in maintaining plant populations and determining range dynamics of species. Thus, it is not surprising that specific germination requirements and dormancy mechanisms have evolved in all major angiosperm clades. In a rapidly changing climate, we face growing pressure to manage, conserve and restore native plant spec...

In this study, we suggested the local convergence of three iterative schemes that works for systems nonlinear equations. earlier results, such as from Amiri et al. (see also by Behl al., Argryos Chicharro Cordero Geum Guitiérrez, Sharma, Weerakoon and Fernando, Awadeh), authors have used hypotheses on high order derivatives not appearing these procedures. Therefore, methods a restricted area ap...

Abstract This paper presents a new multiscale method for analysing water pollutant data located in river networks. The main idea of the proposed is to adapt conventional lifting scheme, reflecting characteristics streamflow network domain. Due complexity domain structure, it difficult apply scheme directly. To solve this problem, we propose algorithm that incorporates flow-adaptive neighbourhoo...

Cylindrospermopsin (CYN) is an emerging freshwater cyanobacterial toxin, and its reports on toxicity toward the human liver kidney tissues has drawn a lot of attention. An appropriate analytical method necessary to determine presence this toxin in water resources including drinking water; therefore, it develop sensitive for CYN detection. In study, we developed simple detection using liquid chr...
