Information about the uncertainties associated with eddy covariance measurements of surface–atmosphere CO2 exchange is needed for data assimilation and inverse analyses to estimate model parameters, validation of ecosystem models against flux data, as well as multi-site synthesis activities (e.g., regional to continental integration) and policy decisionmaking. While model residuals (mismatch be...

the acquisition of argument structures has been studied by a variety of second language acquisition scholars within the past two decades (atay, 2010; can, 2009; chay, 2006, & kras, 2007, among others). in the present study, ‘predicate’ as the most substantial element of a sentence is investigated. there are three english verb-types which seem to be more problematic for persian efl learners:...

A dominating set of a graph is a vertex subset that any vertex belongs to or is adjacent to. Among the many well-studied variants of domination are the so-called paired-dominating sets. A paired-dominating set is a dominating set whose induced subgraph has a perfect matching. In this paper, we continue their study. We focus on graphs that do not contain the net-graph (obtained by attaching a pe...

The evolution of the writing machine from early eighteenth-century concepts to the modern electronic typewriter represents a rich history of innovative efforts by many individuals in several countries. This paper briefly highlights several significant early milestones and then draws particular attention to typewriter developments within the IBM Corporation. After entering the typewriter busines...

We define a ranked trigroupoid as a natural followup on the idea of a ranked bigroupoid. We consider the idea of a derivation on such a trigroupoid as representing a two-step process on a pair of ranked bigroupoids where the mapping d is a self-derivation at each step. Following up on this idea we obtain several results and conclusions of interest. We also discuss the notion of a couplet (D, d)...

Furin inhibitors are promising therapeutics for the treatment of cancer and numerous infections caused by bacteria and viruses, including the highly lethal Bacillus anthracis or the pandemic influenza virus. Development and improvement of inhibitors for pharmacological use require a detailed knowledge of the protease's substrate and inhibitor binding properties. Here we present a novel preparat...

Twenty-four species of mites were found associated with Ips typographus (Linnaeus) collected from pheromone traps in Sweden, bringing to 38 the total recorded for this scolytid. Because three of the species are parasites, it may be possible to use them in biological control of I. typographus. Couplets from an earlier key to these mites in south Germany have been modified to include three of the...

In this article, I try to think through the question, "What distinguishes phenomenology in its original sense?" My intent is to focus on the project and methodology of phenomenology in a manner that is not overly technical and that may help others to further elaborate on or question the singular features that make phenomenology into a unique qualitative form of inquiry. I pay special attention ...
