This work is confined to the preparation and characterization of acrylate polymeric additives. These additives were prepared by estrification of acrylic acid with different alcohols (decyl, 1- dodecyl, 1- tetradecyl and hexadecyl) and then copolymerization of the prepared esters with different moles of styrene. The molecular weights of the prepared copolymers were determined by GPC. The efficiencies of the prepared copolymers as viscosity index and flow improvers for base lube oil were studied. It was found that the best VI improver (D4) afforded value of VI equals to 177. On the other hand, the lowest temperature at which the lube oil doped with the most efficient additive (A1) retains its flow equals -22 C.

Innovation keeps a superlative role for technology based modern teaching and research. In order to achieve the goal, this manuscript has been published for the teacher, researcher, research students (MS, PhD) and students (Undergraduate) in the area of Cell Biology related to plant, animal and human. Modern technology based data on cell Biology like cell structure, function, signaling, physiology, cell metabolic process, division and multiplication, cell cycle, inhibition and regeneration in plant, animal and human have been noted in this manuscript. Moreover, auxin (IAA, IBA), Gibberelin (GA3), cytokinin, abscissic acid (ABA), cytokine, steroid and others hormone's effect on different cell, tissue and organelles growth, regeneration and inhibition have been described well using different research data. In addition, application of Genetic engineering technology in cell growth, regeneration and inhibition has been described well. Kinase influences on oncogene, cell proliferation, differentiation and apoptosis have been delineated. Finally, we believe, this book would be an innovative study in the field of Cell Biology for the academician, researcher and student.
