Anecdotal reports suggest that children often outperform adults when playing Concentration. This is surprising as cognitive processes tend to develop progressively throughout childhood. To date, very few studies have examined this apparent paradox, and with mixed results. In the present study, the ability of 6-year-olds (n = 34), 8-year-olds (n = 48), and adults (n = 38) to play Concentration was examined in a controlled computer-based setup involving eye tracking. The main dependent variables were the number of moves and time in seconds to finish the first nine (out of 12) matching pairs. The results revealed that while 6-year-olds were outperformed by older children and adults, 8-year-olds performed just as well as adults. It is suggested that Concentration may represent a cognitive challenge rarely encountered in the real world, and when playing Concentration, adults seem to use strategies that are effective in real life situations, but may be less appropriate when playing the game.

Metal-semiconductor contact plays a significant role in devices such as transistors, photoemitters, and photodetectors. Here, the AuIn alloy contact gives a state-of-the-art low (contact resistance) in GeSe devices. The of GeSe-AuIn is measured to be 25 kΩ μm under channel carrier concentration around = 2.

Carbonic anhydrases (CAs) are ubiquitous enzymes that catalyze reversibly both the hydration and dehydration reactions of CO and HCO-, respectively. Higher plants contain many different isoforms of CAs that can be classified into α-, β- and γ-type subfamilies. β-type CAs play a key role in the CO-concentrating mechanism, thereby contributing to efficient photosynthesis in the C plants in addition to many other biochemical reactions in plant metabolism.

The self-assembled ferritin protein nanocage plays a pivotal role during oxidative stress, iron metabolism, and host-pathogen interaction by executing rapid iron uptake, oxidation and its safe-storage. Self-assembly creates a nanocompartment and various pores/channels for the uptake of charged substrates (Fe) and develops a concentration gradient across the protein shell. This phenomenon fuels rapid ferroxidase activity by an upsurge in the substrate concentration at the catalytic sites.

Background: Concerns about leadership style and job achievement are global priorities. Most previous investigations have concentrated on one or two of the variables rather than on the sociodemographic characteristics. To properly understand the impact of leadership styles on teacher performance, it is critical to grasp the sociodemographic characteristicsvia a holistic approach to rethinking and improving the existing level.
