based on description and nature of geomorphology, the geomorphologists must be have specific tendency to form of earth crust's landforms and their transformation. but some of related specialists in iran, believe that questa have relationship to old (paleo) geology formations, and by this reason say that questa there is not in iran. whereas anothers such as the writer (author) of this articl, wi...

Generation mean analysis was carried out to estimate the nature andmagnitude of gene effects for sugar yield and its component traits in sweet sorghum[Sorghum bicolor (L.) Moench. Six basic generations, namely P1, P2, F1, F2,BC1P1, BC1P2 of four crosses involving seven diverse parents were evaluated inrainy 2009. The mean performance of the F1 in all the crosses indicated dominantgene effect fo...

The concepts of Nature-based Solutions (NbS) and the Blue Economy (BE) are two prominent sustainability frameworks at forefront policy dialogues. However, investment within BE has been slowed by lack a sufficiently robust operational definition. This definition reduces investor confidence impacts adoption makers practitioners. By considering overlap between it is possible to identify specific s...

Engineering projects often undergo several design iterations before being completed. Information received from other groups working on a project (analysis, manufacturing, marketing, sales) will often necessitate changes in a design. The interaction between different groups associated with a design project often takes the form of informal “negotiation.” This form of interaction commonly arises w...

Introduction Phenotypic expression depends on the interaction between the genotype (nature) and the environment (nurture). This is true for all living organisms, but the physiologic mechanisms that mediate this interaction remain poorly understood. Very early developmental events generally are regarded as being buffered from environmental effects (ie, they are canalized), but it is now clear th...

interaction between human and his environment is always in consideration from scientists and scholars across various scientific spheres. for decades there are not any doubts that enhancement of connection between human and nature in various forms is necessarily influenced by their attitudes, feelings and perspectives toward this environment. however, examining of environmental emotions separate...

this paper shows how game theory can be applied to modeling the interaction between government and manufacturer in implementation of cleaner production. a generic game model based upon ‘two-person non-cooperative’ static game is created to allow various strategic actions being tested by stages, and aid decision making by selecting optimal strategy for both manufacturer and policy maker to reduc...

the track stiffness experienced by a train will vary along the track. sometimes the stiffness variation may be very large within a short distance. one example is when an unsupported sleeper is hanging in the rail. track stiffness is then, locally at that sleeper, very low. at insulated joints the bending stiffness of the rail has a discontinuity implying a discontinuity also of the track stiffn...

A discrete event system (DES) is a dynamic system that evolves in accordance with the abrupt occurrence, at possibly unknown irregular intervals, of physical events. Because of the special nature of these systems, different tools are currently used for their analysis, design and modeling. The main focus of this paper is the presentation of a new modeling approach of Discrete Event Systems. The ...
