BACKGROUND Current evidence suggests that endothelial progenitor cells (EPC) contribute to ischemic tissue repair by both secretion of paracrine factors and incorporation into developing vessels. We tested the hypothesis that cell-free administration of paracrine factors secreted by cultured EPC may achieve an angiogenic effect equivalent to cell therapy. METHODOLOGY/PRINCIPAL FINDINGS EPC-de...

Invariant rectifying and stripping (IRS) curves are used for thermodynamic analysis of a distillation column. Thermal integration of a distillation column with the background process through side exchangers (side reboilers/condensers) is important for energy-efficient design of a distillation column. Thermal integration of a distillation column through side exchangers also improves the exergeti...

BUSINESS PROCESS MODELING USING EXTENDED EPC META-MODEL FOR SCM SYSTEMS Danish Irfan, **** COMSATS Institute of Information Technology, Abbottabad, Pakistan ABSTRACT—This work extends the Event-driven process chain (EPC) with an additional perspective that integrates information about the key performance indicators (KPIs) given by SCM system. The considered extended metamodel makes the unseen k...

In recent years, the integration of Statistical Process Control (SPC) and Engineering Process Control (EPC) has received considerable attentions due to the superiority for the process improvement. However, a drawback of the integration of SPC and EPC may be encountered for monitoring a process. Because EPC would compensate for the effects of underlying disturbances, the disturbance patterns cou...

For increasing first law efficiency in terms of COP and Second law efficiency (Exergetic Efficiency) of VCR systems.the experiment is performed on VCR system to study the effect of silver oxide Nano particle(50nm) in base fluid of ethyl glycol (50:50 ratio with water) with concentration factor 0.02 to 0.06g by volume % on hot side of system (condenser side). For high efficiency out-put, the pla...

during the last years the total cost of lng technology has decreased significantly due to improvements of the liquefaction process. however, many liquefaction plants that are still in operation use a three-cascade refrigeration system. in this paper, an advanced exergetic analysis is applied to better understand the operation of a three-cascade refrigeration system for liquefaction of natural g...

PURPOSE We sought to compare the effects of external pneumatic compression (EPC) and sham when used concurrently with resistance training on performance-related outcomes and molecular measures related to recovery. METHODS Twenty (N = 20) resistance-trained male participants (aged 21.6±2.4 years) were randomized to balanced sham or EPC intervention groups. The protocol consisted of 3 consecuti...

The UK EPC scheme was established in 2007 as a response to the European Union Directive 2002/91/EC (Council of the European Union 2002), which aims to promote improvements on building energy efficiency and requires member states to develop their own scheme of evaluating and labelling the energy performance of buildings (UK Government 2007; Department for Communities and Local Government 2014b)....

Earth–air heat exchanger (EAHE) systems are used to pre-heat or pre-cool air before entering into a building using shallow geothermal energy. Assessment of EAHE is important quantify the profitability these systems. For this purpose, an system built at ICUBE University Strasbourg in northeast France was studied energy and exergy analyses for typical heating period (between 25 February 3 March)....

To realize the high-efficiency and high-performance manufacture of complex high-web panels, this paper introduced electric pulse current (EPC) into the stress relaxation aging forming process of 2219 aluminum alloy and systematically studied the effects of EPC, stress, and aging time upon the microstructure and properties of 2219 aluminum alloy. It is discovered that: (a) EPC greatly enhanced t...
