The availability of data is the main constrain to use factors from one study to another.
With a more realistic approach, we used a complete data set, including events with small amplitude, and we took in consideration the state of the geomagnetic field behind and ahead of SC, and we took as a main constrain to maintain coherence with the older lists.
While low temperature stress remains as the pivotal limitation in rice production in temperate regions (Andaya and Tai 2006), the acclimation to long day conditions of northern rice cultivars represents one of the main constrains during their expansion, and the most evident difference with the cultivars that remained in tropical latitudes (Izawa, 2007).
Considering that sunflower production is expanding to arid regions, tolerance to abiotic stresses as drought, low temperatures and salinity arises as one of the main constrains nowadays.
It highlights the main constrains that discourage such modern concept in building and construction.
From geological perspective, the lithological properties of the roof strata are the main constrains of the emplacement of the bed separation.
Poor physical and chemical properties of sand dune soil are the main constrains in afforestation of sand dune in desertified area.
This method is useful especially in optimization problems, having no explicit constraint on the main lobe width, such as minimizing the sidelobe levels or minimizing main lobe width constrained to a predetermined value of sidelobe level.
In addition, the survey obtained the main reason that partners wanted to live apart (i.e., financial reasons, to keep independence, because of children, not yet ready for living together, other) or the main constraining circumstances (i.e., work circumstances, financial circumstances, housing circumstances, legal circumstances, my partner has another family, other).
Our results show that the operating ranges of both D and ω values in our main model are constrained to satisfy the criterion of λ (Fig. S2E, H), indicating that, as expected, these parameters are particularly important for determining the gradient shape.
