The 408 MHz B 3 . 2 survey
We present a new 408MHz survey (B3.2) carried out with the “Croce del Nord” radiotelescope in Bologna. The survey coordinates limits are −2◦00′ to +2◦15′ in Dec. and 21h to 24h, 00h to 17h in R.A., equivalent to 0.388 sr. The B3.2 is complete to 0.15 Jy but many sources down to 0.1 Jy are included. Our aim was to select a new and complete sample of Ultra Steep Spectrum (USS) radio sources, as t...

Viruses are ubiquitous components of the marine environment, frequently reaching concentrations of 107–108 viruses per milliliter of surface seawater. The majority of these viral particles are bacteriophages (phages). Although the oceans are probably the largest pool of bacteriophages on the planet, the evolutionary relationships of marine phages to phages from other environments are unknown. T...

Let k ≥ 3 be an integer. We show that if d is a positive integer such that the product of any two distinct elements of the set {k−2, k+2, 4k, d} increased by 4 is a square, then d must be 4k(k2−1).

We analyze three-body decays of and . Under the factorization approach, there are tree level diagrams for these decay modes and the transition matrix element of decay is factorized into a form factor multiplied by decay constant and form factor multiplied into weak vertices form factor. The transition matrix element of decay is also factorized into a form factor multiplied into weak vertic...

Analysis and design of structural systems always requires the treatment of uncertainties by using statistical and probabilistic concepts so this can be done in a rational way. It is shown that traditional, deterministic concepts can be easily extended to account for uncertainties. The so-called Monte Carlo Simulation procedures are the key for these developments. By this method, deterministic m...
