We present two abstract models of puzzles, permutation puzzles and cyclic puzzles, which can be modelled as puzzle graphs. Based on these models, we implement two puzzle generators and produce various layouts of the puzzles using graph drawing algorithms. Using these puzzle generators we can create new puzzles. Further, we can create new user interfaces of a puzzle by applying different layout ...

A logic puzzle is a form of entertainment that asks the solver to infer relationships between objects given a set a clues. Each clue is a portion of the solution. A good puzzle is one that is challenging one that that requires the solver to make difficult inferences to realize each part of the solution. My goal was to find an algorithm that, given a solution to a puzzle, would generate a set of...

Introduction: Video games are common cultural issues with great influence in all societies. One of the important cognitive effects of video games is on creating stress on video players. The present research objective was to study different types of stress in players based on video game styles.  Methods: A total of 80 players, aged 18 to 30 years, played four types of video games;  Ru...

The shape and function of plant cells are often highly interdependent. The puzzle-shaped cells that appear in the epidermis of many plants are a striking example of a complex cell shape, however their functional benefit has remained elusive. We propose that these intricate forms provide an effective strategy to reduce mechanical stress in the cell wall of the epidermis. When tissue-level growth...

calpastatin (cast) is a specific inhibiter of calpains, playing a role in meat tenderization and myogenesis. in the present study, the polymorphism of the cast gene of makoei sheep was investigated by polymerase chain reaction and single strand conformation polymorphism technique (pcr–sscp). genomic dna was extracted from whole blood samples collected from 100 sheep. a 622 bp cast exon 1 segmen...

calpastatin (cast) is a specific inhibiter of calpains, playing a role in meat tenderization and myogenesis. in the present study the polymorphism of the cast gene ofkhalkhali goat in azerbaijan province in iran was investigated by polymerase chain reaction and restriction fragment length polymorphism technique (pcr-rflp). genomic dna was extracted from whole blood samples collected from 200 kh...

background: creating a socket with proper fit is an important factor to ensure the comfort and control of prosthetic devices. several techniques are commonly used to cast transtibial stumps but their effect on stump shape deformation is not well understood. this study compares the dimensions, circumferences and volumes of the positive casts and also the socket comfort between two casting method...

background and aims. current chemical methods may not efficiently disinfect dental stone casts. the aim of this study was to investigate if microwave irradiation is effective for disinfection of stone casts. materials and methods. in this laboratory study, three groups (n = 162) of prepared spherical stone beads as carriers with a diameter of 10 mm were inoculated by separately soaking in three...

Exchange rates differ considerably with respect to exchange rate volatility, while they are very similar with respect to the macroeconomic fundamentals — the well known exchange rate disconnect puzzle. The microeconomic structure of foreign exchange markets, especially the existence of noise traders, may be responsible for the excessive volatility in flexible exchange rate regimes. The entry of...
