On thermoeconomics of energy systems at variable load conditions: integrated optimization of plant design and operation
2007
Abstract Thermoeconomics has been assuming a growing role among the disciplines oriented to the analysis of energy systems, its different methodologies allowing solution of problems in the fields of cost accounting, plant design optimisation and diagnostic of malfunctions. However, the thermoeconomic methodologies as such are particularly appropriate to analyse large industrial systems at steady or quasi-steady operation, but they can be hardly applied to small to medium scale units operating in unsteady conditions to cover a variable energy demand. In this paper, the fundamentals of thermoeconomics for systems operated at variable load are discussed, examining the cost formation process an…
Corporate Social Responsibility and Sustainability of Local Community: A Case Study of the Transnational Project in China-Pakistan Economic Corridor
2019
While achieving great benefits, the Belt and Road Initiative (BRI) has triggered potential problems between the transnational projects and local communities in the participant countries. However, there is still a knowledge gap on how corporate social responsibility (CSR) is adopted, and how CSR affects the local community. Based on a context of China-Pakistan Economic Corridor (CPEC), this research exploits a combination of qualitative and quantitative methods to fill the gap. It finds that the CSR activities in the CPEC project are initiated by the long-term CSR initiative. Organized by the professional CSR foundation in an autonomous environment, the panoramic CSR activities are governed …

Contribution to the knowledge of the therophytic flora of Sardinia
2003
The abundance of therophytes, largely contributes to the naturalistic value of Sardinia. Moreover, most of the annual species belonging to the Sardinian flora have an historical and cultural value, as they followed the men in his migrations and still reflect the different ways of traditional land exploitation characterising the island. As a matter of fact, the development of human technology increased number and frequency of the annual plants of Sardinia. Nowadays, annuals occur in several habitats of the island, where they play a primary ecological role, both as biomass producers and protecting the soil from rill erosion during the rainy season, at least where the environmental factors do …
The genus Orobanche (Orobanchaceae) in Sicily
2011
The taxa of Orobanche occurring in Sicily and on the surrounding islets have been surveyed in the field and in herbaria. In total, 23 species occur in the region. O. litorea is found to be distinct from O. minor and O. thapsoides from O. canescens. O. crenata and O. ramosa are serious pests that cause heavy losses to broad bean and tomato cultures, respectively.

Exploring natural products-based cancer therapeutics derived from egyptian flora
2020
Abstract Ethnopharmacological relevance Egyptian plants are a rich source of natural molecules, representing considerable biodiversity due to climate variations between the Northern, Southern, Eastern and Western regions of the country. Sinai is considered a precious nature reserves preserving flora, fauna, marine organisms, and historical habitats with ancient origins. Here, traditional medicinal approaches have been used for hundreds of years. Healthy lifestyles, low levels of stress and microbial infections, and a dependence on flora and herbal medicine might in combination explain why the burden of cancer is lower in some regions than in others.

This empirical research proposal is to be considered in the framework of “Business to Consumer” relationships and is addressed to the flowers a…
