Input-output budgets for dissolved inorganic nitrogen (DIN) are summarized for 24 small watersheds at 15 locations in the northeastern United States. The study watersheds are completely forested, free of recent physical disturbances, and span a geographical region bounded by West Virginia on the south and west, and Maine on the north and east. Total N budgets are not presented; however, fluxes ...

Clear-cutting is today the primary driver of largescale forest disturbance in boreal regions of Fennoscandia. Among the major environmental concerns of this practice for surface waters is the increased mobilization of nutrients, such as dissolved inorganic nitrogen (DIN) into streams. But while DIN loading to first-order streams following forest harvest has been previously described, the downst...

Differential interaction nets (DIN) have been introduced by Thomas Ehrhard and Laurent Regnier as an extension of linear logic proof-nets. We prove that DIN enjoy an internal separation property: given two different normal nets, there exists a dual net separating them, in analogy with Böhm’s theorem for the λ-calculus. Our result implies in particular the faithfulness of every non-trivial denot...

This study deals with the cumulative pitch variations in DIN male contacts. A connector provides a separable interface between two subsystems of an electronic system. DIN is a series of connector which stands for Deutsch Institut fur Normung. They are used for applications like switching, transmission, radio base stations, control units and machines. Connector manufacturing involves stamping, m...

The effect of the din distribution on the error probability of the detection test is studied here that when a class of randomly rotated spherical Ridges is used. The detection test is performed by a focused correlation detector, and the spherical codes studied here form a randomized orthogonal constellation. The colluders create a din-free forgery by uniform averaging of their individual copies...

DNA damage-inducible (din) genes in Bacillus subtilis are coordinately regulated and together compose a global regulatory network that has been termed the SOS-like or SOB regulon. To elucidate the mechanisms of SOB regulation, operator/promoter regions from three din loci (dinA, dinB, and dinC) of B. subtilis were cloned. Operon fusions constructed with these cloned din promoter regions rendere...

This paper will report on lessons learned from two studies using blended learning courses involving past and present experience of the authors. Will also discuss the importance of online asynchronous discussions in the teaching and learning process. The paper concludes with suggested guidelines for the use of asynchronous online discussions, considered useful for instructors who teach for the f...

We have identified many dark-inducible (din) genes that are expressed in Arabidopsis leaves kept in the dark. In the present study we addressed the question of how plant cells sense the depletion of sugars, and how sugar starvation triggers din gene expression in suspension-cultured cells of Arabidopsis. Depletion of sucrose in the medium triggered marked accumulation of din transcripts. Suppre...

Irrigated agriculture can modify the cycling and transport of nitrogen (N), due to associated water diversions, water losses, and changes in transport flow-paths. We investigate dominant processes behind observed long-term changes in dissolved inorganic nitrogen (DIN) concentrations and loads of the extensive (465,000 km2) semi-arid Amu Darya River basin (ADRB) in Central Asia. We specifically ...
