This work aims to study the distribution and quantification of genus Rhizosolenia known for its abundance diversity among planktonic diatoms at 9 sampling stations in Nador lagoon during 2 seasons (spring summer 2018). The collected were identified morphologically using an inverted optical microscope. A total 10 species have been listed including: bushsolei, R alata forma alata, bergonii, cochl...

We find a lower bound to the size of finite groups detecting a given word in the free group. More precisely we construct a word wn of length n in non-abelian free groups with the property that wn is the identity on all finite quotients of size ∼ n2/3 or less. This improves on a previous result of BouRabee and McReynolds quantifying the lower bound of the residual finiteness of free groups. A gr...
