Disaster Risk Management of Cultural Heritage Sites in Albania.
No full textUNESCO has a vital role to play in constructing a global culture of disaster preparedness and mitigation, building in the minds of people a Disaster Risk Management of Cultural Heritage Sites in Albania culture of resilience to risk, promoting awareness, education and capacity and foremost a different way to approach the domain of Disaster Risk Reduction (DRR) and preparedness. UNESCO is also the secretariat of the 1972 World Heritage Convention, of which the properties have recently been the focus of substantial advancement in securing better capacity in risk management and reduction.
Since UNESCO is engaged in important actions for the protection of cultural heritage it implements several projects in post disaster scenarios. This book has been elaborated as a final outcome of the project “Natural Risk Preparedness and Mitigation - Building capacity in the field of risk mitigation for Cultural Heritage properties in Albania” during the period 2011-2013.
The project aimed to streamline disaster risk management in the Country, using its World Heritage properties as demonstration sites. The project was conceived to assist the country in order to enhance its capacity for Disasters Risk Management (DRM) and advancement in seismological and geological
vulnerability of Cultural Heritage properties
Biohydrogen production from food waste in batch and semi-continuous conditions: evaluation of a two-phase approach with digestate recirculation for pH control
No full textThe research investigated the production of Biohythane in a two-phase anaerobic digestion process treating food waste as substrate. Preliminary batch assays were carried out at initial organic loadings of 15, 20, 25 and 30 kg TVS m?3, in stirred 1.5-l reactors at 55 °C. The results showed all hydrogen was produced within the first 24 h after feeding and the highest load tested gave the maximum hydrogen production (0.047 m3 H2 kg?1VS, H2 30%). Similar loadings were then tested in a two-phase system. Hydraulic retention times of 3 and 12 days were applied to the first and second reactor respectively. In order to keep the pH at ?5.5, either supernatant or whole digestate from the methanogenic reactor was recirculated to the first phase. Results showed that hydrogen was produced (0.117 Nm3 kg?1 VS, 47.7%) when recirculating whole digestate with an organic loading rate of 20 kg TVS m?3 day?1

No full textResponse functions and charge transition densities for monopole excitations in (e, e′) and (e, e′x) reactions of 16O and 40Ca
No full textThe energy behaviour of the monopole (e, e') and (e, e'x) response functions of 16O and 40Ca at q = 100 MeV/c is discussed in the framework of a self-consistent RPA-SK3 theory based on the 1plh energy continuum. The microscopic structure of the resonant states is inferred from the analysis of proton and neutron monopole transition densities in the most populated decay channels. The role of the RPA final-state interactions and ground state correlations is investigated
Reactivity of M(ArN-N=NAr)(CO)(PPh3)2 with aryldiazonium salts (M = rhodium(I), iridium(I); Ar = p-CH3C6H4, p-FC6H4)

[Ir(ArNN:NAr)(CO)(PPh3)2]BF4 and [Rh(CONArN:NAr)(N2Ar)(PPh3)2]BF4. The latter are formed by an insertion
reaction. IR and NMR spectral date are discussed
Photoreactions of 12C, 16O and 40Ca in self–consistent RPA theory. II. Unpolarized (γ, p) and (γ, n) angular distributions below pion threshold
No full textThe (γ, p), (γ, n) and inverse capture reactions in 12C, 16O and 40Ca below pion threshold have been analysed in the frame of a self-consistent RPA theory with a Skyrme force (Sk3). E1 and E2 transitions in LWA are present in the calculation. Thereby, EC linked by gauge invariance to the effective interaction are included in the predicted cross sections. Through an overall comparison with the available experimental data, we attain, in the present context, a good fit of data up to 80 MeV. The observed symmetric behaviour of (γ, p) and (γ, n) angular distributions is well reproduced. The rôle of nuclear correlations on the action of EC by gauge invariance is discussed
The one–nucleon energy continuum in RPA–Sk3 40Ca(e, e′) nuclear responses at q < 550 MeV/c
No full textLongitudinal and transverse nuclear responses on 40Ca (e, e′) electron scattering have been calculated at q≤550 MeV/c in self-consistent HF-SK3 and RPA-SK3 nuclear models with the full treatment of the one-nucleon energy continuum. We analyze the quenching phenomena of the charge response in terms of he RPA-SK3 nuclear dynamics. The isoscalar and isovector longitudinal currents, which fulfil the continuity equation with the Skyrme RPA hamiltonian density, are derived. The missing strength is located in the isoscalar channel
