there is widespread recognition today that we are living in a period of profound technological, social, economic and political change, and that this process of change is accelerating. yet, there is less certainty about the nature and meaning of these changes—whether they should be regulated or liberalized, supported or resisted— and the kind of world they are leading to. despite these uncertai...

Novel Visualization and Algebraic Techniques for Sustainable Development Through Property Integration. (December 2006) Vasiliki Kazantzi, B.S., University of Thessaloniki, Greece; M.E., Texas A&M University Chair of Advisory Committee: Dr. Mahmoud M. El-Halwagi The process industries are characterized by the significant consumption of fresh resources. This is a critical issue, which calls for a...

OBJECTIVES Here we aim to describe in detail the logical procedure and philosophical approach to establish a minimally access aortic valve replacement programme in the current era. METHODS A real example of a National Health Service Trust in the United Kingdom has been described in a step-wise manner. RESULTS The outcomes of the new procedure established in this fashion are reported and the...

conclusions small dose of clopidogrel (75 mg) may lead to rare, life-threatening dah, so physicians should be aware of the possibility of dah after neurointervention in patients who have respiratory distress, worsening alveolar infiltrates accompanied by hemoptysis. introduction diffuse alveolar hemorrhage (dah) is a very rare complication but acute and life-threatening event. clopidogrel has g...

interventional techniques aim to find safer and better ways to treat vascular diseases even in many instances, the interventional radiology solutions has been considered the only treatment option for the patients. interventional radiologists are specialists who perform minimally invasive procedures instead of surgery or other treatments. these procedures apply various imaging and catheterizatio...

The urban development process displays regressive tacit-dominant knowledge areas and their tacit level would impede their movements during multi-level knowledge transfers among stakeholders. The accuracy of a knowledge may be distorted when recipient stakeholders fail to understand a specific knowledge for its purpose. Earlier studies by the authors had highlighted complex yet dynamic environme...

Having the possibility to systematically evaluate objectives of different nature at the same time is becoming crucial to operate processes, plants and production sites under more sustainable conditions. Most often, this multi-objective nature is tackled by combining all individual objectives into a global Weighted Sum (WS). This approach is widespread because it is easy to use and understand, b...

China's geosciences data sharing has progressed significantly but is still facing some key questions that need to be solved Because of the data’s insufficiency, it has limited use in modern scientific research. The documents and metadata for the data are insufficient. The scientific data service is dated. The data application procedure is troublesome, etc. All this has become a bottleneck affec...

Recent facility location allocation problems are engaged with social, environmental and many other aspects, besides cost objectives.Obtaining a sustainable solution for such problems requires development of new mathematical modeling and optimization algorithms. In this paper, an uncapacitated dynamic facility location-network design problem with random budget constraints is considered. Social i...

Pectin methylesterase was extracted from potato tubers and partially purified in a single chromatographic step at large industrial scale. The preparation obtained in this way matched the temperature and pH profile of the species reported earlier by Puri et al. (Food Chemistry 8:203-213, 1982) and was enriched 23 times relative to the original potato tubers on a dry matter basis. Potato PME indu...
