Here the lower-bound Theorem of Limit Analysis is applied to historic masonry vaults modeled as continuous no-tension bodies where singular stress fields can take place. To this aim, by following...doi:10.1007/978-3-319-99441-3_118Aguinaldo Fraddosio...
Although it can reflect the situation of the HMS in Tianjin, the level of the HMS varies by region and city and cannot fully reflect the national level, which may limit the generalizability of our findings. We will broaden the scope of the sample and increase the number of city comparisons...

Based on the conceptual fra- mework illustrated in Fig. 1, we evaluated country-level food security by considering both climate change and dietary changes during the historical period of 1990–2018 and the future climate horizon of 2060. The climate conditions spanning these two periods could be...
We showed that some climate measures provide more co-benefits across the SDGs than others; yet, to reach global GHG-emissions neutrality before the end of the century to stay below the Paris Agreement temperature-increase limit, action must be taken across all economic sectors. Countries will nee...
The USA-CAN community has the highest risk index, while the BRA community and the AGR-FRA community have the largest increase in the RECSI of the seven communities. In addition, 60%, 50%, and 70% of countries face medium and above (high and very high) EDI risk, HHI risk, and RICI...
The area of culti- vated land that can be retired from water resources is the lower limit, which is the minimum area that can be retired. Any further reduction in the area of retired land will threaten ecological security. Table 4. Water consumption of townships in Manas County. Township,...

is not fast enough to achieve the emission reduction level required in the international climate regime targeting to limit the warming below 2 °C compared to pre-industrial levels in the long term. The results show that even if the reduction target pledged in NDC is attained by 2030, the ...
The sandy texture (Table 5) and the acidic parent material of the soils (Table 4) limit nutrient retention, thus soils cannot buffer natural and management induced pH changes, which leads to further nutrient leaching and a further decrease of the pH-value. A low pH affects plant availability...
