What is the antibody titer test? The antibody titer is a test that detects the presence and measures the amount of antibodies within a personâs blood. The amount and diversity of antibodies correlates to the strength of the bodyâs immune response.
The Centre for Renewable Energy Sources and Saving (CRES) is the Greek organisation for Renewable Energy Sources (RES), Rational Use of Energy (RUE) and Energy Saving (ES). CRES has been appointed as the national co-ordination centre in its area of activity. CRES was founded in September 1987 by Presidential Decree 375/87.
According to Bohr, the amount of energy needed to move an electron from one zone to another is a fixed, finite amount. These zones are known as energy levels (or sometimes called electron shells). At the lowest energy level, the one closest to the atomic center, there is a single 1s orbital that can hold 2 electrons. At the next energy level, there are four orbitals; a 2s, 2p1, 2p2, and a 2p3. Each of these orbitals can hold 2 electrons, so a total of 8 electrons can be found at this level of energy. In larger and larger atoms, electrons can be found at higher and higher energy levels (e.g. 3s and 3p). Moving between Levels. As Neils Bohr showed, it is possible for electrons to move between energy levels. Light contains energy.
