The Speed of the Passing of Time as Yet Another Facet of Cosmic Dark Energy

The topological speed of light which may be used to compute the density of ordinary energy and dark energy of the cosmos is replaced by dimensionless quantity taken from Special Relativity. The said quantity may be interpreted as akin to time dilation ergo a notion topologically equivalent to the speed of the passing of time or the difference of elapsed time between two events in Einstein’s Relativity Theory. This results via Newton’s kinetic energy into the well-known observationally confirmed and accurately measured 4.5 and 95.5 percent of ordinary and dark Cosmic Energy density respectively.

Pass Appearance Time and Pass Attempts by Teams Qualifying for the Second Stage of FIFA World Cup 2014 in Brazil

This study aimed to clarify the difference between the not qualified teams and the qualified teams to 2nd stage in the Pass Appearance Time and passes attempted at all group stage games of World Cup 2014 and compared with World cup 2010. Results indicated changes in passing in modem football tactics. Actual playing time is represented as Net Playtime in this study. Pass Appearance Time is calculated by Net Playtime divided by passes Attempted. Pass Appearance Time of each team for the all Group stage games was calculated and compared with World cup 2010. No difference was revealed in the 2014 data between teams that did and did not qualify, though the 2010 data revealed differences. World cup 2010 data suggested that increasing passes attempts and lessening Pass Appearance Time were effective in qualifying for the 2rid stage. World cup 2014 data, however, suggested that diversity of tactics was important.

Optimization of ultrasonic-assisted freezing of Penaeus chinensis by response surface methodology

Objectives:Optimization of ultrasonic-assisted freezing of Penaeus chinensis by response surface methodology was studied in order to(1)obtain frozen Penaeus chinensis of high quality and(2)provide practical guidance for the application of ultrasonic-assisted freezing in Penaeus chinensis.Materials and Methods:Three independent and major variables were selected,including initial ultrasonic temperature(℃),ultrasonic power(W)and ultrasonic time(s on/2 s off).On the basis of one-factor experiments,17 groups of experiments were established by response surface methodology according to Box-Behnken design.Using multiple regression analysis the experimental data were fitted into a second-order polynomial equation,which was tested by proper statistical methods.Results:The optimal ultrasonic conditions were as follows:initial ultrasonic temperature 0℃,ultrasonic power 180 W,ultrasonic time 5 son/2 s off.Under the optimization conditions,the time of passing through maximum ice crystal generation zone was 105.500 s,which was very close to the predictive passage time of 101.541 s.Conclusions:Initial ultrasonic temperature,ultrasonic time and ultrasonic power played an important role in the process of ultrasonic-assisted freezing of Penaeus chinensis.Response surface methodology was used to optimize the three factors in ultrasonic-assisted freezing,which could greatly shorten the time of passing through the maximum ice crystal generation zone and maintain the tissue structure of Penaeus chinensis well.
