Cooperating to improve healthcare in Arab countries

This brief note presents a few examples of successful health collaboration to improve healthcare in Arab countries. Considerable growth has been noticed in the past years in the health sector of the Middle East and North Africa region countries due to the need to address health service capacity gaps and improve the quality of health infrastructure. The rising population coupled with the aging demographic is expected to drive healthcare demand in the Arab region, augmenting its demand. In order to meet this demand, a lot of progress within the public sector has been made and several initiatives have taken place to create awareness of the most common diseases affecting the region. Among the steps undertaken in order to face the shortage of experience of medical personnel and the rising cost of the delivery of health services, the most noticeable ones relate to major investments within the realm of healthcare provision. However, country-specific drivers of disease burden should inform financial and research investments, prevention efforts, health policies, and health system improvement initiatives for all countries along the development continuum. Moreover, health gains will need to be sustained by supporting interventions on income, education, and fertility as drivers of health improvement

Modelling of the neutron production in a mixed beam DT neutron generator

Compact DT neutron generators based on accelerators are often built on the principle of a mixed beam operation, meaning that deuterium (D) and tritium (T) are both present in the ion beam and in the target. Moreover, the beam consists of a mixture of ions and ionized molecules (D, T ions, and ionized D-D, T-T and D-T molecules) so the relevant source components come from T(d, n), D(t, n), D(d, n) and T(t, 2n) reactions at different ion energies. The method for assessing the relative amplitudes of different source components (DD, DT, TT) is presented. The assessment relies on the measurement of the neutron spectrum of different DT components (T(d, n) and D(t, n) at different energies) using a high resolution neutron spectrometer, e.g. a diamond detector, fusion reaction cross-sections, and simulations of neutron generation in the target. Through this process a complete description of the neutron source properties of the mixed beam neutron generator can be made and a neutron source description card, in a format suitable for Monte Carlo code MCNP, produced
