This study was carried out in the Regional Park of San Rossore (Italy) where we found natural regeneration of Stone pine (Pinus piena L.) in an even-aged stand of pine. The objectives of our study were to characterize the forest structure of the Stone pine stand and to quantify the natural regeneration of pine. Our results show that natural regeneration of P. pinea in the Park of San Rossore is…
Italy was one of the countries severely affected by the Covid-19 pandemic. An analysis of the factors that played a role in the spread of this epidemic is necessary. However, the assessment of which factors may be specific, and which may contribute the most is complex and involves a high degree of uncertainty. The main objective of this study is to evaluate and analyse the statistical associati…
This chapter describes spin-wave excitations in nanosized dots and rings in the presence of the vortex state. The special attention is paid to the manifestation of the competition between exchange and dipolar interactions in the spin-wave spectrum as well as the correlation between the spectrum and the stability of the vortex. The calculation method uses the dynamic matrix for an all-discrete s…

This study characterizes the zonation of coastal vegetation in six coastal sites in Malta. The vegetation sequence on the coastal zone is predictable and displaces in response to changes in shoreline. The halophyte Limbarda crithmoides was used as an indicator species to ‘locate’ the position of the sequence. The vegetation surveys were used to construct a Gaussian distribution model for th…
To investigate plastic pollution in rivers, the Tara schooner collected samples from 9 of the main European rivers from May to November 2019. The objectives of the present study are the quantification of the microplastic (MP) contamination and the identification of the chemical nature of microplastics. Thus, extraction methods and automated computer processing for polymer characterization were …
Physical activity is one of the most basic human functions, and it is an important foundation of health throughout life. Physical activity apports benefit on both physical and mental health, reducing the risk of several diseases and lowering stress reactions, anxiety and depression. More specifically, physical activity is defined as "any bodily movement produced by skeletal muscles that require…
