Meeting the goals of Paris Agreement poses significant challenges to provide renewable energy for power, heating, transport, and industrial sector. Both green hydrogen methane are considered key carriers reaching these climate targets. However, future needs an effective infrastructure deployment highly uncertain, particularly concerning timely substantial expansion electricity generation in Eur...

The airline industry faces economic challenges making it paramount that they provide satisfactory service to customers relative to their expectations. This study uses a service quality-adjusted data envelopment analysis (SQ-adjusted DEA) to study US-based airline carrier operational efficiency. We found that airlines can overcome the traditional tradeoff between quality and productivity. Using ...

In this paper we conduct the analysis of economic and ecological aspects of alternative energy carriers based on biomass sources. These sources encompass short rotation copies, forest wood residue, wood industry residues, waste wood as well as energy crops. In 2010 the energy output from all these biomass-based alternative energy carriers was about 4000 PJ in the EU-15. We show which energy out...

This paper introduces a general optimization approach for power dispatch and conversion in power systems that include multiple energy carriers such as electricity, natural gas, and district heating. The classical Economic Dispatch method is modified in order to account for certain system properties, such as the possibility of conversion between the different energy carriers, or local overproduc...

introduction pistachio (pistacia vera l.) is one of the most important export crops of iran which has an important role in non-petroleum exports and has over $800 million benefit per year. however, production of this crop faces many problems in main production centers, especially in energy efficiency and productivity. the pistachio is a native crop of iran and syria. the major producers of pist...

this paper, examines the factors that influence energy intensity- the ratio of energy consumption to gdp- in 42 oil exporting and none-oil exporting countries in the period 1985 to 2009. the research applies panel data models to analyze the impacts of oil price, gdp, exchange rate, co2 emissions, population, surface area and productivity on energy intensity. an attempt is made in this paper, to...

Background: Gold nanoparticles are emerging as promising agents for cancer therapy and are being investigated as drug carriers, photothermal agents, contrast agents and radiosensitisers.Objective: The aim of this study is to understand characteristics of secondary electrons generated from interaction of gold nanoparticles GNPs with x-rays as a function of nanoparticle size and beam energy and ...
