Programs in quantum gravity often claim that time emerges from fundamentally timeless physics. In the semiclassical program, arises only after approximations are taken. Here we ask what justifies taking these and show seems to sneak when answering this question. This raises worry approach is either unjustified or circular deriving no-time.

Time should be understood in relation to others, not as a private matter. Therefore time, including its use and experience, is subject negotiations, power relations inequality. This article utilises the concept of household economy money management systems model explore couples’ practices time. The research questions are: what time can identified, how are couples differentiated? study uses inte...

the target of this study was to investigate the possibility of mdf productionfrom eucalyptus camaldulensis wood. mdf fibers were produced applying threelevels of steaming time. laboratory mdf boards were produced using thegenerated fibers and different pressing temperature and time. physical andmechanical properties of mdf panels were measured using relevant eu testmethods and were statisticall...

assembly line production is one of the widely used basic principles in production system. the problem of assembly line balancing deals with the distribution of activities among the workstations so that there will be maximum utilization of human resources and facilities without disturbing the work sequence. research works reported in the literature mainly deals with minimization of idle time i.e...
