AbstractAcademics have had numerous responsibilities during the centuries. However, now with global climate changes and the attendant, looming crises, it is increasingly crucial that administrators, faculty members, graduate, undergraduate students, staff members and alumni work together with governmental, non-governmental and industrial members in envisioning societies that are truly sustainable. The visions must then be effectively and efficiently implemented in numerous locations throughout t...

The Kyoto target for Romania was to reduce its carbon dioxide emissions by 8 % from the 1989 levels. The 1989 emissions were around 260 million tones. In 2000 the net CO2 emission - some 125 million tones - were 54% of the net CO2 emission in the reference year -1989, leaving some 115 million tones as a reserve or as a tradable resource to other countries that can not met their Kyoto targets.

Since Romania is now an EU Member State, such a plan is a must to enhance life quality, in order to meet the objectives of the National Strategy for Sustainable Development. Having regarded to this Strategy and the Kyoto Protocol signed in 1997, this paper provides the results from a study of am...

Wireless local area networks (WLAN) are an increasingly used communication technology employing energy of radiofrequency (RF). Although the power emitted by WLAN systems is relatively small (in Europe, a maximum of 100 mW is permitted in the classic 2.4 GHz frequency band), concerns about possible health effects risks from exposure to radiofrequency (RF) fields originating on WLAN are sometimes expressed by the general public. In such a context, this paper presents results of a survey conducted ...

Methane (CH4) is one of the greenhouse gases, with an ability to trap heat in Earth's atmosphere 21 times greater than carbon dioxide (CO2) per unit mass and in the same period of time. Because the lifetime of methane in the atmosphere is relatively short, it could be kept under control. Wastewater treatment plants (WWTPs) are anthropogenic sources of CH4 emissions.

AbstractDue to the continuously increasing trend in the costs of the traditional fossil fuels, the development of residential or commercialbuildings with reduced energy needs becomes a significant and more pressing scientific challenge. At the same time, consumersare increasingly demanding more comfortable buildings, where the energy needs are addressed using locally available renewableenergy resources. Consumers also require a higher level of security, supervision, and control of the building, ...

Convergence, that is the concentration of human populations into small areas, has been common throughout history. However, convergence has now reached historically unprecedented levels. Historically, convergence has tended to increase the long-term risk to humanity caused by many factors, including the associated environmental damage. Large cities appear to be at greater risk of unforeseen disasters, and may even collapse when some maximum sustainable size is exceeded. Based on a review of publi...

In this study, Coal Fly Ash (CFA), a byproduct of coal combustion power plants, was used as an adsorbent to remove color from locally-obtained pulp mill effluent (PME). Batch adsorption studies were conducted to determine the adsorption parameters that would result in the maximum color removal from PME at the lowest CFA dosage and process cost. The effects of operating variables on color removal were studied by varying: 1) CFA dosage, 2) initial PME pH, and 3) contact time. The findings indic...

With the rapid development of electric vehicles (EV), more and more EV batteries will intensively face the retirement. If they are treated improperly, EV batteries might pose a serious threat to human health and environment. Therefore, recycling spent EV battery is full of significance. However, the recycling system and specific policies have not be well established in China. This paper aims to evaluate several recycling subsidy policies being considered and tested in China for their influenc...

The soil was heavily polluted up to values of total hydrocarbon equal to 1800 mg/kg. The consortium was selected from the microorganism living in the Fidenza soil, bioaugmented and finally reinoculated in the bio-pile for soil treatment. The approach is absolutely innovative, due to the presence not...
