No full textCorporate Ownership and Control: International Trends
No full textThe book "Corporate Ownership and Control: International Trends" examines the corporate governance systems in nine countries (the USA, Italy, Spain, Turkey, New Zealand, China, Brazil, India, Nigeria) with particular emphasis on corporate ownership and control issues. This book picks up several very important issues related to corporate governance. Is corporate ownership and control still nationally driven issue or not? What sort of corporate governance regulation is more effective – soft or strict? Does family ownership produce a new model for corporate ownership and control? Is corporate law able to account all those national peculiarities of corporate ownership and control on one side, and respect the worldwide best practices in corporate governance on another side
Biofilm as an adaptation strategy to extreme conditions
Full text linkBiofilm is the most successful and widely distributed form of life on earth, it is not simply structured collections of cells attached to surfaces but is a dynamic complex biological system able to respond to environmental changes. The biofilm characteristics make it unique and central to microbial evolution and adaptation. The ability to establish biofilms is a key trait for microorganisms growing in extreme environments like extreme temperature, high radiation, acidic or alkaline pH values, heavy metal pollution, and high salinity. In this article, we report the main features of biofilm and how these characteristics make biofilms a successful survival strategy in extreme conditions. All aspects examined in this article help to explain why biofilms are a successful survival strategy in extreme conditions and why the ability to establish biofilms is a key trait for microorganisms growing in extreme environments
Particulate PAHs in two urban areas of Southern Italy: impact of the sources, meteorological and background conditions on air quality
No full textThe present work studied how much the meteorological parameters and the emission sources can influence the particulate polycyclic aromatic hydrocarbons (Invalid Journal Information PAHs) concentrations in two areas located in Southern Italy (Bari and Taranto). It was found that when the vehicular traffic is the main source of PAHs, there is a negative correlation between ambient temperature, wind speed and PAHs concentration (Bari). This is because these parameters are generally correlated with the dispersion capacity of the atmosphere. In the presence of a large industrial area, the wind direction becomes an important parameter able to determinate large changes in PAHs concentrations. This happened in Taranto where PAHs concentrations are exceptionally high. During the study the seasonal trend of particulate PAHs and PM10 was compared. PM10 did not show a significant seasonal cycle during the year because it is conditioned from a high regional aerosol background, especially during the summertime. On the contrary, particulate PAHs exerted distinct seasonal variation with higher concentrations in the winter and lower concentration during other months of the year. This evidence suggested that PAHs concentrations can be considered a more reliable index for air-quality assessment. In order to identify an index that considers the contributions of other particulate PAHs, it is necessary to calculate the carcinogenic potency of total PAHs (i.e., total BaPeq) obtained by the sum of the benzo[a]pyrene equivalent concentration (BaPeq) for each PAH
