Optimum Filtered Backprojection Images by Geometric Modeling: With Application to Medical Imaging


Author(s): Atefeh Hasan-Zadeh*

This article pays to prove that the number of times that the projections from some angles in filtered backprojection image (which are equally spaced) can be calculated by the surface area of the convex body and (symplectic) Holmes-Thompson volume in notions of Fourier transform, Finsler metrics and Minkowski spaces. For this purpose, these parameters are calculated by the surface area of a convex body of the corresponding projective spaces and Holmes-Thompson volume in notions of integral geometry (Radon and Fourier transform), Finsler Geometry (and Minkowski spaces) and symplectic geometry...

Ubiquitous Role of Ribosomal DNA in the Viability of Living Cells and Organisms


Author(s): Natalia S Kupriyanova; Andrey A Vergun; Alexey P Ryskov*

Ribosomes are among the most ancient and important substructures of the cell, retaining the organization of common features in all living organisms. The genes responsible for the synthesis of nucleic acids and proteins that form ribosomes, as well as those that serve the processes of these genes, the maturation of transcription products, and the transition of mature products to the active state, together form the largest polygenic complex...

A Comprehensive Review on the Physical and Chemical Properties of the Three Generations of Biofuels


Author(s): Mehdi Ardjmand* and Farid Jafarihaghighi, Mohammad Salar Hassani, Neda Bazel, Hasanali Bahrami

The shortage of fossil fuel resources and the dramatic increase in population have raised many concerns about fuel supply in the years ahead. Researchers are now focusing on renewable fuels, and biodiesel is one of those renewables. Four generations of biodiesel have been reported today and many studies have been done to optimize and enhance their performance. The present review article examines the physical and chemical properties of three generations of biodiesel...

Molecular Regulation of Preimplantation Development of Farm Animals


Author(s): Nasser Ghanem*; Romysa Samy; MD Fakruzzamana; Ibrahim Abdalla Hassan Barakat; Kong IK

Preimplantation period is the early series of events required to establish pregnancy. Therefore, it is one of the main research focus all over the world. The early classic studies was based on in vivo model to monitor the success of fertilization based on superovulation and embryo flushing at different time points. However, application of in vitro embryo production has advanced our understanding on the molecular regulation of the events encompass this crucial period. Indeed, different approaches and molecular techniques have been performed to get deep insights into the molecular mechanisms controlling early events of preimplantation embryo development of several mammalian species.
