Various tumor cells may exhibit different genetic or phenotypic characteristics.This Playing Cards phenomenon of cancer cells, known as Tumor Heterogeneity, is responsible for multiple cancer sites caused in a single patient through metastases.It is possible that the biopsy of the most accessible metastasis will not provide enough information to re
In rapidly changing environments populations and species face a challenge to remain adapted and avoid extinction or replacement by fitter types.If evolutionary adaptation cannot keep pace with the speed of environmental change populations will exhibit varying degrees of maladaptation with respect to the current environmental state.Reciprocal transp
In this paper, there were deduced three new lifetime distributions of serial-parallel and parallel-serial networks, their distribution being approached by means of analytical and Monte-Carlo methods.The novelty of the distribution consists in the fact click here that the number of subnets is random, governed by the Poisson and Logarithmic distribut
Excessive use of chemical fertilizers in rice fields can reduce soil pH.Elemental P in acid soils is generally not available to plants because it is bound by Fe and Al elements; therefore, it is necessary to make an effort to optimize the availability of P in the soil by improving soil pH with the addition of dolomite Cushion lime supported by inor
