We present a new method to construct a stability diagram of a serial quantum dot system. The partition function and average charge numbers of the system were calculated by means of imaginary-time path integrals. Consequently, the stability diagram for the quantum dot system was obtained by projecting the average charge numbers of the system to the gate voltage-phase space. To verify the...

In this work, density functional theory (DFT) has been performed to investigate high-pressure phase transitions of TlX (X = N, P, As). Both standard GGA and LDA functionals with norm-conserving pseudopotential are used to compare each other in recent work which the calculation results are reported in form GGA (LDA). Based on the previous theoretical predictions, B3-to-B1 (B4-to-B1 for TlN) are...

The present study employs exponential decay pulse-electric field inductions to enhance sex reversal of Nile tilapia eggs in suspensions for monosex-male. The novel technique was the pilot study to initiate the usage of natural androgen hormone of $\textit{Butea superba}$ (Red Kwao Krua) extract instead of our previous electroporation medium of 17$\alpha$ - methyltestosterone (MT). The eggs of...

There are various strategies for solving physics problems in mechanics. Each strategy contains particular steps that are appropriate for particular topics in mechanics. One of the most important steps in almost all strategies is drawing a free-body diagram (FBD). It is an essential skill students must have in order to solve physics problems successfully. In this study, we conducted a survey of...

Over the last 30 years, physics education research revealed that students already have a number of ideas about how physical systems behave, even before they start to study physics. In many cases, these ideas differ from accepted scientific ideas. Other research showed that it is difficult for students to change their initial ideas and found that traditional instruction is relatively...

The complexity of physics has implications for the teaching of physics today. That physics is a very complex subject is shown from the research on problem solving and misconceptions that has dominated the field during the past 30 years. It is commonly known that students have difficulty for solving physics problems because of mathematic skill. In this study 120 high school physics students...

In crime scene reconstruction, the patterns of bloodstains serve us opportunities to determine the location of bloods source which can be referred to the position of victim or weapon used. For medium velocity blood spatters, generally the victim is hit by a blunt object (such as a hammer or a baseball bat). The trajectories of blood drops are in projectile motions. In this work, the projectile...
