Toward a Lemaitre-Hubble-Riess Cosmology

However, if A tends to 0 and ⁇ the external space density has been discarded by A. Einstein could mutually cancel the positive and negative volumetric acceleration tensors and the General Relativity could not be extended to the external space. Otherwise, A. Friedman provided alternatives to the equations of Einstein, showing that without the term,

Selection of the coordinate system is essential for rotation problems. Otherwise, mistakes may occur due to inaccurate measurement of angular speed. Approximate inertial coordinate system selections for rotation problems should be the gravitational field of the celestial body higher than the object being rotated: (1) the Earth fixed Cartesian coordinate system for normal rotation problem;

Forced axi-symmetric response of polar orthotropic circular plates of linearly varying thickness resting on Winkler type of elastic foundation has been studied on the basis of classical plate theory. An approximate solution of problem has been obtained by Rayleigh Ritz Method, which employs functions based upon the static deflection of polar orthotropic circular plates. The

We attempt to obtain Pythagorean triples by a simple method consisting in transforming the relation between integers 2 22 ) na(ba  into an equation innby introduction of a parameter n /b  . By this way we obtain easily Pythagorean triples for each choice of  . Following this example we introduce also a

In this short review some aspects of applications of free electron theory on the ground of the Fermi statistics will be analysed. There it is an intention to attempt somebody’s attention to problems in widespread literature of interpretation of conductivity of metals, superconductor in the normal state and semiconductors with degenerate electron gas. In literature

Climate change is currently an eminent theme in politics. Thereby, so-called greenhouse gases such as CO2 are considered as the real cause for the temperature rise of the global atmosphere. This theory traces back to measurements of Tyndall at the end of the 19th century which revealed that CO2 absorbs thermal radiation, in contrast to

Sustainable Hydrogen Production Identifying and building a sustainable energy system are perhaps two of the most critical issues that today’s society must address. Replacing our current energy carrier mix with a sustainable fuel is one of the key pieces in that system. [1] Bio-hydrogen production from waste materials Hydrogen is a valuable gas as a

Localized Intracoronary Gamma-Radiation Therapy to Inhibit the Recurrence of Restenosis after Stenting Although the frequency of restenosis after coronary angioplasty is reduced by stenting, when restenosis develops within a stent, the risk of subsequent restenosis is greater than 50 percent. We report on a multicenter, double-blind, randomized trial of intracoronary radiation therapy for the treatment

Electron energy-loss spectroscopy in the TEM Electron energy-loss spectroscopy (EELS) is an analytical technique that measures the change in kinetic energy of electrons after they have interacted with a specimen. When carried out in a modern transmission electron microscope, EELS is capable of giving structural and chemical information about a solid, with a spatial resolution
