Preliminary Work I started my preliminary work because, when I started my measurements using 2 coils used in experiments to deflect electrons from and electron gun. While testing for the deflection of beta particles, I found that beta radiation was scattered in a very large cone, I can not get any readings with amount of beta radiation scattering. So I would have to construct some type of shielding for this

However, in vitro studies have shown, that the beta-isoform is far more stable than the alpha-isoform (Wagman) Despite their structural and enzymatic similarities their genomes reside on different chromosomes. GSK3, like many other kinases, is affected by various phosphorylation events, and thus can require “prime phosphorylation”. Phosphorylation of the N-terminal serine in GSK3 at ser21 in alpha and ser9 in beta, results in inhibition of the enzyme. Inactivation of GSK 3 β

    The concept of beta has gained prominence due to the pioneering works of Sharpe (1963), Lintner (1965) and Mossin (1966). There are many studies that examine the behaviour and nature of beta. These studies include the impact of the length of the estimation interval, the stability of individual security beta as compared to portfolio beta, factors influencing the beta as well as the stability of beta in various market conditions. In theory, market capitalisation weighted indices are preferred as compared

    a) Beta in financial terms is the amount of systematic risk brought by vulnerability of movements in the market. Beta of equity is found by using the following formula: First of all, in order to determine the beta of firm’s equity we need the covariance of stock return and market return (i.e. return index). Then variance should be determined. We use formulas for: Covariance Variance R i-stock return R m - market return P-probability As there are 5 states of economy, in our case

In about 4,000 years, the motion of Alpha Centauri, who’s proper name is Rigel Kentaurus, will carry it close enough to Hadar that they will appear to be a magnificent double star. Because of the distance away from Earth that Alpha and Beta Centauri are (approximately 90 parsecs), they will be an optical double. As they sit today, the

Overall, the resultant portfolio should have a beta of zero. The positions in the risk-free asset cancels out and the net investment is zero.

    The beta mixed effects model parameters can be estimated from the Bayesian approach. Bayesian inference on beta mixed models is not straightforward because the posterior distribution is not analytically available. Markov Chain Monte Carlo (MCMC) technique is the standard approach to fit these models \citep{zuniga:2013}. In practice, this approach comes with a wide range of problems in terms of convergence and computational time. Moreover, the implementation itself can be problematic, especially
