No other element essential for life takes as many forms in soil as nitrogen (N), and transformations among these forms are mostly mediated by microbes. Soil microbiology thus plays yet another crucial role in ecosystem function: in most terrestrial ecosystems N limits plant growth, and thus net primary production—the productive capacity of the ecosystem—can be regulated by the rates at which so...

for the first time, it is mentioned in the interpretation of muqātil bin sulayman that: ‘nadr ibn al-harith, who was familiar with the traditions of ancient iran, claimed that the qur’an contained ‘legends of the ancients’; i.e. stories like those of rostam and esfandiyār. following muqātil, commentators often quoted this view, associating and translating ‘legends of the ancients’ with and into...

background & aim: a meta-analysis refers to the statistical synthesis of results from a series of studies and has been used to estimate pooled prevalence of human diseases. in this study, we review some statistical issues regarding the meta-analysis of the prevalence of human diseases such as statistical software and programs, transformations of prevalence rate, assessment of heterogeneity, and...

we prove that every r-quadratic metric of scalar flag curvature with a dimension greater than twois of constant flag curvature. then we show that generalized douglas-weyl metrics contain r-quadraticmetrics as a special case, but the class of r-quadratic metric is not closed under projective transformations

A new class of rank one transformations with singular spectrum * Abstract. We introduce a new tool to study the spectral type of rank one transformations using the method of central limit theorem for trigonometric sums. We get some new applications. 1. Introduction The purpose of this paper is to bring a new tool in the study of the spectral type of rank one transformations. Rank one transforma...

While software methodology encourages the use of libraries and advocates architectures of layered libraries, in practice the composition of libraries is not always seamless and the combination of two well-designed libraries not necessarily well designed, since it could result in suboptimal call sequences, lost functionality, or avoidable overhead. In this paper we introduce Simplicissimus, a fr...

In the two-Higgs-doublet model (THDM), generalized-CP transformations (φi → Xijφj where X is unitary) and unitary Higgs-family transformations (φi → Uijφj) have recently been examined in a series of papers. In terms of gauge-invariant bilinear functions of the Higgs fields φi, the Higgs-family transformations and the generalized-CP transformations possess a simple geometric description. Namely,...

We discuss how ontologies can be used to facilitate the construction of transformations between XML documents. We introduced a method to compose transformations for XML documents reusing existing (smaller) transformations to define transformations for more complex documents. Linking the types on which these transformations are built to the elements (concepts) of an ontology supports the identif...
