It is well known that the Galilei algebra is a sub algebra of Poincare algebra in one space dimension more. 1 This fact allows us to relate relativistic Poincare and Galilean theories. An interesting point is that Galilei transformations in two space dimensions are contained in the usual Poincare transformations? This enables us to present Poincare spin zero wavefunctions as Fourier transforms ...
Abstract Introduction: Many industries such as manufacturers of pesticides, paints and pharmaceutics produce large amounts of 2,4,6-Trichlorophenol (TCP). Due to its high toxicity and environmental pollution TCP is classified as a leading hazardous compound. The aim of this study was to investigate the TCP removal by using zeolite (clinoptilolite) modified with surfactants from the aqu...
background: recently, tissue engineering has developed approaches for repair and restoration of damaged skeletal system based on different scaffolds and cells. this study evaluated the ability of differentiated osteoblasts from adipose‑derived stem cells (adscs) seeded into hydroxyapatite/ tricalcium phosphate (ha‑tcp) to repair bone. methods: in this study, adscs of 6 canines were seeded in ha...
The complete list of Poisson–Lie structures on 4-d Galilei group is presented.
The effects of solid state synthesis process parameters (time and temperature) and primary calcium precursor on the amount of produced α-tricalcium phosphate (Ca3(PO4)2 or α -TCP) have been investigated. α-TCP was synthesized by firing of stoichiometric amount of calcium carbonate and monetite in first group and calcium carbonate and brushite in the second group, once at 1350°C for 3,6,8,16 h d...
In this study, the effect of 1,2,3-trichloropropane (TCP) as trifunctional monomer on thermophysical properties of synthesized poly(ethylene tetrasulfide) (PETS) is investigated. To this end, different amounts of TCP (0-40 mol. % of halide-containing monomer) were incorporated into the structure of polysulfide polymer via interfacial condensation polymerization. Measuremen...
A vector space G is introduced such that the Galilei transformations are considered linear mappings in this manifold. The covariant structure of the Galilei Group (Y. Takahashi, Fortschr. Phys. 36 (1988) 63, 36 (1988) 83) is derived and the tensor analysis is developed. It is shown that the Euclidean space is embedded the (4,1) de Sitter space through in G. This is an interesting and useful asp...
