In this study, we used a spatially explicit landscape model, LANDIS, to simulate the changes of fire regime and forest landscape under four larch caterpillar disturbance intensity levels scenarios in Huzhong forest area, northern of Da Hinggan Mountains. The results indicate that larch caterpillar disturbances would decrease fine fuel load and increase coarse fuel load in the 300 simulation years. Larch caterpillar disturbances would decrease fire frequency in the first 200 years, and the disturbances also decrease fire intensity and fire risk in the early and late stage of simulation. Larch caterpillar disturbances would decrease the area percent of larch cohorts and increase the proportion of white birch, and increase the degree of aggregation of white birch as a result of its strong seed dispersal and colonization ability. Disturbances would also decrease the mature and over-mature larch cohorts and increase all cohorts of white birch, especially the mature and over-mature cohorts. Larch caterpillar disturbances will decrease the stability of forest landscape, therefore,some measures preventing in- sect outbreak and ensuring the sustainable management of forest ecosystem should been taken in the study area.展开更多

So, technology is approached as a simple efficiency increase whose source is unknown. In terms of established economics view, technology is like a "black box" that cannot be predicted. As the creator of the concept of"creative destruction", Joseph Schumpeter (1883-1950) caused significant changes in terms of the view of neoclassical economics about technology. On one hand, Schumpeter created a new point of view about the concept of"innovation" by using key concepts, such as "invention", "imitation", and "business cycles". Schumpeter's "creative destruction" concept carries out the role of a new map for the new institutional economics trend which accepts "technology" as an institution. On the other hand, if one is to understand why the ideology differs between neoclassical economics and new institutional economics, "transaction costs" should be analyzed. Since, transaction costs and creative destruction have a relationship between each other; Schumpeter and Coase's ideas are resembling each other. While doing this, this paper will try to discuss the question of how to accept the technology as "external" instead of "internal" limit neoclassical economics. In this process, it will primarily base the dimension on the concept of"technology" developed by Schumpeter. The second station is an inquiry between Schumpeter's and Coase's ideas about technology. Although new institutional economics (NIE) and neoclassical economics can be confused, they can be seperated from each other by the way they look at technology. Because, technology is accepted as an external theme by neoclassical economics, on the contrary, NIE acceptes technology as an internal fact. One of the most important reasons why technology is internal in terms of NIE can be evaluated by "transaction costs". As a result, the author will give effort to create a critical presentation in order to readdress the viewpoint of mainstream economics about "technology".展开更多

In [7] We have obtained some properties of Dt(G, x) and its coefficients. Also, we have calculated the total domination polynomials of complete graph, complete bipartite graph, join of two graphs and a graph consisting of disjoint components. In this paper, we presented for any two isomorphic graphs the total domination polynomials are same, but the converse is not true. Also, we proved that for any n vertex transitive graph of order n and for any v ∈ V(G), dt(G, i) = 7 dt(V)(G, i), 1 〈 i 〈 n. And, for any k-regular graph of order n, dr(G, i) = (7), i 〉 n-k and d,(G, n-k) = (kn) - n. We have calculated the total domination polynomial of Petersen graph D,(P, x) = 10X4 + 72x5 + 140x6 + 110x7 + 45x8 + [ 0x9 + x10. Also, for any two vertices u and v of a k-regular graph Hwith N(u) ≠ N(v) and if Dr(G, x) = Dt( H, x ), then G is also a k-regular graph.展开更多

The page number is a measure of the quality of a book embedding which is the minimum number of pages in which the graph G can be embedded. In this paper, the authors discuss the embedding of the generalized Petersen graph and determine that the page number of the generalized Petersen graph is three in some situations, which is best possible.展开更多
