One of the main controlling parameters in diesel engine combustion is the fuel – air mixing process that has direct effects on engine performance and pollutant emissions, reviewing over previous literature showed that split injection strategies could satisfy this purpose very well. For the first time and in this paper, pilot and double injection strategies were combined and formed new triple in...

The purpose of this paper is studying the status of the administrative system evolution in Mazandaran university of medical science with emphasizing on root factors. Materials and methods: In this research, three aspects, organizational structure, jo...
The amount of pollutant gases in the atmosphere has reached a critical state due to an increase in industrial development and the rapid growth of automobile industries that use fossil fuels. The combustion of fossil fuels produces harmful gases such as carbon dioxide, nitrogen monoxide (NO), soot, particulate matter (PM), etc. The use of Dimethyl Ether (DME) biofuel in diesel engines or other c...

PURPOSE OF THE STUDY Older adults often have problems finding their way in novel environments such as senior living residences and hospitals. The purpose of this study was to examine the types of self-reported search strategies and cues that older adults use to find their way in a virtual maze. DESIGN AND METHODS Healthy, independently living older adults (n = 129) aged 55-96 were tested in a...
he future of healthcare delivery systems will depend on heir ability to provide the best care at the least cost. In he clinical laboratory, this translates to ensuring that lecreased test use means appropriate use. The latter is nhikely to occur unless clinical laboratories provide practicing physicians with advice on test strategy and iterpretation of results. Effective clinical laboratory con...
Testing is the process of stimulating a system with inputs in order to reveal hidden parts of the system state. We consider a variant of the testing problem that was put forward in the model-based diagnosis literature, and consists of finding input patterns that definitely discriminate between different constraint-based system models. We show that this problem can be framed as a game played bet...
The purpose of this paper is to show that for a dense G set of three smooth convex bodies with nowhere vanishing curvature in the C topology k the open billiard obtained from these convex bod ies determines a potential the one that de nes the natural escape measure of this billiard which is non lattice This result generalizes one of the results obtained in a previous work of A Lopes and R Marka...
Scholars have been investigating the quick emergence of digital platforms, essentially through the lens of digital native firms. If there is limited occurrence of platforms launched by incumbent firms such as Daimler (Car2Go, Moovel) or Johnson Controls (Panopix), the economics of their strategic responses through platforms by incumbents merit attention. This paper provides the first largescale...
