The volcanic Comoro Islands, located in the Indian Ocean in between mainland Africa and Madagascar, host several thousand African baobabs (Adansonia digitata). Most of them are found in Mayotte, which currently belongs to France, as an overseas department. We report the investigation of the largest two baobabs of Mayotte, the Big baobab of Musical Plage and the largest baobab of Plage N’Gouja. The Big baobab of Musical Plage exhibits a cluster structure and consists of 5 fused stems, out of which 4 are common stems and one is a false stem. The baobab of Plage N’Gouja has an open ring-shaped structure and consists of 7 partially fused stems, out of which 3 stems are large and old, while 4 are young. Several wood samples were collected from both baobabs and analyzed via radiocarbon dating. The oldest dated sample from the baobab of Musical Plage has a radiocarbon date of 275 ± 25 BP, which corresponds to a calibrated calendar age of 365 ± 15 yr. On its turn, the oldest sample from Plage N’Gouja has a radiocarbon date of 231 ± 20 BP, which translates into a calibrated age of 265 ± 15 yr. These results indicate that the Big baobab of Musical Plage is around 420 years old, while the baobab of Plage N’Gouja has an age close to 330 years. In present, both baobabs are in a general state of deterioration with many broken or damaged branches, and the Baobab of Plage N’Gouja has several missing stems. These observations suggest that the two baobabs are in decline and, most likely, close to the end of their life cycle.

Cluster Development

The article aims at investigating the commonalities and differences between cluster policies in selected East Asian and Southeast Asian countries: Thailand, Singapore, South Korea, and China, to outline the Asian model of a cluster policy. Clusters play a significant role in the economic development of these countries, and some practical experiences from Asia may be used to shape the cluster policy in the recovery process after the COVID-19 pandemic. The conducted research contributes to a better understanding of the cluster formation process, cluster development, and policy aims in the analyzed countries. In Singapore and South Korea, which are among the most innovative countries in the global economy, cluster policy is to a great extent part of innovation policy, focusing on facilitating the networking and cooperation between science and business, the flow of knowledge, transfer of technology, and developing innovative technologies of key economic importance. In China and Thailand, which are developing countries, there is a much stronger role of foreign direct investments, which take the central place in the cluster structure. However, one common characteristic of cluster development patterns in all the analyzed countries is a top-down approach, where clusters are emerging and developing mostly as a result of governmental decisions and public programs.

The bonds structure, atomic coordination situation and local cluster structure in SrBi2Ta2O9 were analyzed by means of the Atomic Environment Calculation (AEC), and then the SrBi2Ta2O9 crystal was decomposed into 20 pseudo-binary crystals with the crystal decomposition method. The chemical bonds properties, such as effective valence electron density and iconicity of the individual bond were calculated by the dielectric chemical bonds theory. And the correlation between chemical bonds properties and spontaneous polarization of the bismuth layered ferroelectrics was established. Finally, the spontaneous polarization in ferroelectric SrBi2Ta2O9 and other relevant ferroelectrics were calculated, which are in good agreement with the experimental values and other theoretical calculated values.
