Fig. 8(a)–(c) details the processes involved in ball milling process, ranging from collision stage (Fig. 8(a)–(b)) to new deformation path (Fig. 8(c)). For instance, Ali et al . (2018) used different mixing fractions of Fe 2 O 3 into Ti 3 C 2 T x matrix in order to improve the storage performance of Ti 3 C 2 T x (MXene)/Fe 2 O 3 nanocomposite via a facile and scalable dry ball milling method.

Underground mining techniques have progressed significantly over the past years, including using remote controlled machinery. Drills assist in creating holes descending underground. If miners are required to work underground, drills can also be used in ensuring the holes are large enough to serve as a portal for miners to enter.

The dataset is already binned, thus representing population counts per 100 meter intervals (=bins). Now I''m wondering if better binning would have been possible, thus I was thinking about using e.g. Freedman–Diaconis rule for estimating the bin width. Therefore, I pretend that e.g. 110 people living in a bin at x=200 meters is like 110
