Here’s how to approach this question Calculate the mass of the lamina, M, by integrating the mass density ρ(x,y)=xy over the region R. Step 1 Given a lamina in the first quadrant bounded by y=x24, x=0, and y=9 with density ...
Thus, a uniform lamina with the geometry of a circle will have the centre of mass coinciding with the geometric centre for the circular shape. Provided a complex lamina can be broken down into a set of shapes for which the centre of mass is known, the centre of mass for complex shaped ...

the homeoprotein may generally be determined using experimental models and/or clinical trials. The optimal dose may depend upon the body mass, weight, or blood volume of the subject. The use of the minimum dose that is sufficient to provide effective therapy is usually preferred. Design and ...

Ribosomal RNA (rRNA) gene (rDNA) transcription by RNA Polymerase I (Pol I) drives cell growth and underlies nucleolar structure and function, indirectly coordinating many fundamental cellular processes. The importance of keeping rDNA transcription under
Inhibition of Pol I transcription leads to cell cycle arrest associated with apoptosis, senescence or autophagy depending on the cell type [14-17]. Hence, rDNA transcription has been proposed to directly couple cell growth to cell cycle progression and to influence the decision of a cell to ...
