Memetic Algorithm with Filtering Scheme for the Minimum Weighted Edge Dominating Set Problem

The minimum weighted edge dominating set problem (MWEDS) generalizes both the weighted vertex cover problem and the problem of covering the edges of graph by a minimum cost set of both vertices and edges. In this paper, we propose a meta heuristic approach based on genetic algorithm and local search to solve the MWEDS problem. Therefore, the proposed method is considered as a memetic search algori

Pre-clinical effects of highly potent MEK1/2 inhibitors on rat cerebral vasculature after organ culture and subarachnoid haemorrhage

Background: Aneurysmal subarachnoid haemorrhage (SAH) is a variant of haemorrhagic stroke with a striking 50% mortality rate. In addition to the initial insult, secondary delayed brain injury may occur days after the initial ischemic insult and is associated with vasospasms leading to delayed cerebral ischemia. We have previously shown that the MEK1/2 inhibitor U0126 improves neurological assessme

Experimental investigation on heat transfer characteristics of various nanofluids in an indoor electric heater

Heat transfer characteristics of an electric heater were experimentally investigated by using various fluids in this paper, including Cu-EGW (a mixture of ethylene glycol and DI-water), Al2O3-EGW, Fe3O4-EGW nanofluids. A 4:6 mixture of ethylene glycol and deionized water was used as the base liquid. All these nanofluids were prepared by ultrasonic treatment, and nanoparticle mass concentration of

Over-rich combustion of CH4, C2H6, and C3H8 +air premixed flames investigated by the heat flux method and kinetic modeling

An uncommon non-monotonic behavior of the temperature dependence of adiabatic laminar burning velocity has been found in over-rich methane+air flames at equivalence ratio, ϕ = 1.4. To find out the universality and reasons of this turning point, methane, ethane and propane + air flames are studied both experimentally by the heat flux method and numerically using GRI-mech, USC-mech, UCSD-mech, FFCM

A role for hepatic lipase in chylomicron and high density lipoprotein phospholipid metabolism

The rate of removal of phosphatidylethanolamine and phosphatidylcholine from the plasma of rats treated with antiserum to hepatic lipase was measured. The hepatic lipase antiserum was injected intravenously into animals prior to injection of 32P-labeled chylomicrons or 32P-labeled high density lipoproteins. In experiments in which 32P-labeled chylomicrons were injected, antiserum treatment inhibit

Var finns den oberoende professorn?

Ett generellt problem för professorn är att finna en lämplig avvägning mellan rollen som oberoende bedömare av samhällsutvecklingen och rollen som expert eller konsult åt externa uppdragsgivare. Detta dilemma diskuteras här med utgångspunkt från den växande kopplingen mellan professorskåren inom nationalekonomi och den offentliga sektorn under de senaste 10–15 åren. Någon enkel lösning på motsättn

Spurring remanufacturing through public procurement – A case study in the Swedish automotive industry

There is a growing political consensus in the European Union (EU) to move away from the current resource intensive “linear” economic system, towards an innovative system aiming at closing material loops – the so-called circular economy. An array of new policy proposals targeting all stages of the life-cycle of a product are needed to facilitate the transition to a circular economy in Europe. While

Employees as ambassadors: embracing new role expectations and coping with identity-tensions

PurposeTo provide an employee perspective on ambassadorship in the context of corporate communication, the purpose of this paper is to explore how employees relate to and experience ambassadorship.Design/methodology/approachThe study has a qualitative approach, and the empirical material consists of semi-structured interviews with, and focus groups of, employees of seven organizations in both the

Structural basis for the interaction of the chaperone Cbp3 with newly synthesized cytochrome b during mitochondrial respiratory chain assembly

Assembly of the mitochondrial respiratory chain requires the coordinated synthesis of mitochondrial and nuclear encoded subunits, redox co-factor acquisition, and correct joining of the subunits to form functional complexes. The conserved Cbp3-Cbp6 chaperone complex binds newly synthesized cytochrome b and supports the ordered acquisition of the heme co-factors. Moreover, it functions as a transla

Taking Action for Urban Nature: Innovation Pathways Directory

What are the enabling conditions and driving forces for nature-based solutions in the context of urban sustainability transitions? And how do innovation pathways play a role for nature-based solutions? Innovation pathways are a journey: from the initial idea and its demonstration, to its broader uptake within policy, industry and society. The Innovation Pathways Directory provides an entry point t
