Owing to the advancement of wireless technologies, there is a strong public perception of increasing exposure to Radiofrequency (RF) electromagnetic fields (EMF). The aim of this study is to determine the evolution of EMF in the environment, and consequently, human exposure to them, over a period of about two decades, spanning from the end of 2003 until February 2022. The study is based on data collected by two non-ionizing radiation monitoring networks in Greece.

Studies recommend that organisations adopt innovative and flexible business models to generate added value for customers and other stakeholders as a survival and growth strategy. However, such measures require business ecosystems which encourage co-creative engagement.

Safety limits and exposure assessment methods were developed and are regularly updated to mitigate health risks. Continuous radiofrequency EMF monitoring networks and in situ measurement campaigns provide useful information about environmental EMF levels and their variations over time and in different microenvironments.

For the large La(III) ion, the bis-adduct (Cp)La(C≡NCy) could also be synthesized and characterized. The metal-ligand interactions, focusing on the comparison of the actinides and lanthanides as well as on the competition of the two different ligands for M, were elucidated using the Quantum Theory of Atoms in Molecules (QTAIM) and Natural Bond Orbital (NBO) models.

Methods: Ac-DOTATOC was administered to thirty-nine patients with various somatostatin-receptor-positive tumors. Baseline and follow-up Ga-DOTATOC PET/CT, lab tests, and renal scintigraphy were obtained.
