in this study, the disadvantages of wood, which is widely employed in producing music instruments, are discussed. for example, high moisture sensitivity, low impact resistance, and time-consuming procedure as well as various properties of different species or in several parts of one specimen which are the main problems of wooden music instruments are extensively discussed in this paper. many ma...

Consider the following probabilistic one-player game: The board is a graph with n vertices, which initially contains no edges. In each step, a new edge is drawn uniformly at random from all non-edges and is presented to the player, henceforth called Painter. Painter must assign one of r available colors to each edge immediately, where r ≥ 2 is a fixed integer. The game is over as soon as a mono...

The addition of cottonwood and ash sapwood powder to YPSSl2 medium influenced the mycelial growth of 13 species of freshwater lignicolous Ascomycetes and Hyphornycetes. These species fall into three groups with respect to their responses to the presence of leached or non-leached wood powder. Neither wood type showed strong inhibitory effect on the mycelial growth of the species. Leaching di...

Assume G is a graph, and k,d,m are natural numbers. The d-defective (k,m)-painting game on played by two players: Lister Painter. Initially, each vertex has k tokens uncolored. In round, chooses set M of vertices removes one token from chosen vertex. Painter colors subset X which induces subgraph G[X] maximum degree at most d. A v fully colored if received m colors. wins the end some there with...

Noise impacts resources and visitor experience in many protected natural areas, and visitors can be the dominant source of noise. This experimental study tested the efficacy and acceptability of signs asking visitors to be quiet at Muir Woods National Monument, California. Signs declaring a "quiet zone" (at the park's Cathedral Grove) or a "quiet day" (throughout the park) were posted on a rand...
