Biological Activity of Extracts from Artemisia arborescens (Vaill.)L.: An Overview about Insecticidal, Antimicrobial, Antifungal and Herbicidal Properties
Following their evolutionary process, many plants have oriented their secondary metabolism towards the production of complex molecules, which often show an apparent protective function against pests (insects, fungi, viruses, but also competing plants). The identification and the study of such compounds could play a significant role in the frame of the development of new techniques for sustainable plant protection, where they could help in achieving the goal of a reduction in the use of the most highly-impact chemicals. The Mediterranean basin, with its very large biodiversity, represents a huge reservoir of highly promising plant material, which is scarcely explored as far. Indeed, preliminary trials have allowed to state that a large number of Mediterranean plants possess definite biological activities, that give them a great interest as potential raw matters for many industrial sectors. Among these, Artemisia arborescens (Vaill.) L., a common shrub from the family Asteraceae, was found to exert a wide range of biocidal activities, which may represent the starting point for the best exploitation of this plant. In this paper, a thorough review is made about the studies that have been carried out worldwide about the composition and some of the biological activities of A. arborescens. Original data are included and discussed, concerning trials about the evaluation of the activity of essential oil and water extracts against selected mealybugs, fungal and microbial strains, as well as against the germination capacity of the seeds of several common weeds

Data for Gupta et al., "Estimating the Meridional Extent of Adiabatic Mixing in the Stratosphere using Age-of-Air", JGR:Atmospheres,
Model data and post-processed data supporting the creation of the manuscript "Estimating the Meridional Extent of Adiabatic Mixing in the Stratosphere using Age-of-Air" submitted to JGR:Atmospheres in August 2022.
1) The netCDF files created through post-processing of full model data in FORTRAN are shared in the /data/ directory. These file contains the zonal mean circulation statistics based on Gupta et al. (2020), age-of-air transport diagnostics based on Linz et al. (2021), and the novel \Gamma-\Theta circulation streamfunction introduced in this study. The /data/ directory also contains MATLAB .mat data files for the transport diagnostics obtained from WACCM. 150 days of actual GFDL-FV3 model data in the northern hemisphere, between 0.1 hPa-500 hPa pressure levels is also provided to support external computations and validation.
2) The Jupyter notebook used for final computation and figures production is provided in .ipynb, .html and .pdf formats in /code/. All the files referred to in the notebook are stored in the /data/ directory.

Hypericum spp.: A Resource from Wild Mediterranean Flora for the Treatment of Mild Depression
The genus Hypericum holds about 480 species (Crockett and Robson, 2011), widely spread throughout the world. A large part of them grows wild in the Mediterranean areas: 30 Hypericum taxa (26 species and 4 sub-species) have been detected in Italy, and about one third of them (11 taxa) are native to Sicily (Castellano and Spadaro, 2010). Actually, traditional and folk medicines in many parts of the world use Hypericum species for a plenty of different purposes. The most important are certainly two: the treatment of wounds and burns (because of the strong effects stimulating the formation of new tissue and lenitive of pain), and the therapy of moderate to mild depression (due to its remarkable hypnotic and tranquilizer effect, with specific antidepressant and anxiolytic effects). Besides these well-known actions, other biological effects of Hypericum extracts have been recognized in time, including antimicrobial, antioxidant, antiproliferative activities. Although many compounds have been identified in Hypericum extracts, however, which compound, or mixture of compounds, is exactly responsible for every specific pharmacological action it is not perfectly clear as far. The available literature agrees in ascribing a great importance to three active compounds, namely hypericin and pseudohypericin (two naphthodianthrones), and hyperforin (a phloroglucinol derivative). The occurrence of these substances in Hypericum extracts is highly variable, as an effect of both genetic factors (species and/or subspecies) and environmental conditions (growing site or cropping techniques). This paper makes a review of the information available in the newest literature about botanical and agronomical concerns, chemical composition and biological activity of Hypericum species, with a special emphasis to the treatment of depressive states. Original data about the content of hypericin, pseudohypericin and hyperforin in several Hypericum species and populations coming from different Italian sites are also exposed and discussed
Legal Protection of Databases
The computer-based databases have made significant value addition in information products and services, and have enabled fast access to information. The growing role of databases for information access has brought to the fore questions of legal rights of the owners and users of the databases. The paper examines current developments in the legal protection of databases. The developments in the European Union (EU) and USA show significant departure from the existing practices in many countries. The salient aspects of these developments, the relevant provisions of the international agreements, the proposed WIPO draft database treaty, the legal implications of the protection of databases within the context of promotion and progress of science, and the role of the library and information science profession, are also discussed
