A river network is a typical completely open system formed by interconnected river channels. The interactions between the imports of a river (water and sediment) and the channel will cause the change of the channel patterns. This is actually a feedback between the erosion and the sedimentation states of the channel via an adjustment of the sedimentcarrying capability of the stream. This feedbac...

This study is motivated by problems related to environmental transport on river networks. We establish statistical properties of a flow along a directed branching network and suggest its compact parameterization. The downstream network transport is treated as a particular case of nearest-neighbor hierarchical aggregation with respect to the metric induced by the branching structure of the river...

photodegradation of dicamba, an ionizable herbicide, using tio2 supported on hzsm-11 zeolite was investigated. four photocatalysts with different weight percentages (wt%) of tio2 were evaluated: 3%, 10%, 30% and 50%. the effects of the catalyst concentration, the initial ph value and the repeatability of the photocatalytic activity after multiple cycles of reuse were also evaluated. results sho...

hexavalent chromium is mobile and hazardous in the environment. electrokinetic remediationof chromium (iv)-contaminated soils is intended either to remove or to reduce cr (vi) to cr (iii). this studyexamines the effectiveness of utilizing edta and acetic acid solutions as alternative electrolytes in theelectrokinetic (ek) process, with coupled nano-scale zero-valent iron (nzvi) as a barrier for...

Abstract This study provides a design diagram which involves series of pragmatic strategies for ecological remediation and restoration plain river networks in the Yangtze River Delta. The is composed two stages: first concerns reduction pollutants, including those from non-point sources, point sediments; second, biological habitat, riparian zone aquatic habitat. A case Gehu Lake was used as an ...

We introduce a formal model of cost-sensitive fault remediation, derive an exact algorithm for solving the special case of deterministic observations, and demonstrate it on two example problems. This effort is part of two self-healing software projects that attempt to use collected data for better decision making in emerging autonomic systems.

BACKGROUND Cognitive remediation (CR) is a psychological therapy, effective in improving cognitive performance and functioning in people with schizophrenia. As the therapy becomes more widely implemented within mental health services its longevity and uptake is likely to depend on its feasibility and acceptability to service users and clinicians. AIMS To assess the feasibility and acceptabili...

Remediation Therapy CRT is designed to improve memory and boost thinking power. Cognitive Remediation Therapy for Schizophrenia: Theory and Practice.

Cognitive remediation is a technique derived from.Cognitive remediation therapy ai...

Abstract Context Increasing fragmentation of rivers caused by barriers continues to impact watersheds, especially disruption fish migration patterns and loss access spawning nursery habitats. Infrastructure expansion ageing installations exacerbate the problem, reducing effectiveness management in addressing barriers. Reduction watershed connectivity requires effective tools capable guiding riv...
