BACKGROUND AND OBJECTIVES: This study aims down to evaluate the ability of chloride magnesium- aluminium- layered double hydroxides (4:1) for nitrate adsorption from the soil solution in successive cropping periods. METHODS: The study was conductedunder long-term cropping periods, including first crop): bell pepper; second crop: mentheae; third crop: cher...

In spite of the intense efforts of metrics researches, the impact of object-oriented software metrics is for the moment still quite reduced. The cause of this fact lies not in an intrinsic incapacity of metrics to help assessing and improving the quality of object-oriented systems, but in an unsystematic, dispersed and ambiguous manner of defining and using the metrics. In this paper we define ...

This paper presents the EarthTutor authoring tool, a multi-layered system designed to remove the technical hurdles preventing teachers from having full control over the structure of their lessons, without sacrificing the power and technical flexibility required for an effective ITS implementation. EarthTutor reduces the ITS design problem to a series of related but independent layers. Each laye...

The effects of link annotations on user search performance in hypertext environments having deep (layered) and shallow link structures were investigated in this study. Four environments were tested—layered-annotated, layered-unannotated, shallow-annotated, and shallow-unannotated. A single document was divided into 48 sections, and layered and unlayered versions were created. Additional version...

Offshore wind is a key part of the change toward renewable energy sources. farm developments are moving to sites that characterized by increased water depths and layered soil profiles, e.g., in North Sea. Suction caisson–based jacked structures expected be increasingly used support turbines at such sites. Experience suction caissons serving as foundations for offshore limited. The mechanisms go...
