Seasonal surface drainage of sloping farmland : a review of its hydrogeomorphic impacts [PDF]

open access: yes, 2015
The combination of runoff-generating areas (saturated soils) and overland flow concentration in features such as drainage ditches makes sloping farmland vulnerable to soil erosion.

BOD5 dynamics in three vertical layers in free-water surface wetlands

open access: yesEgyptian Journal of Aquatic Research, 2022
This paper introduces a first-order variable residence time (VART) model, the so-called BOD-VART model, to estimate the biochemical oxygen demand (BOD) in built wetlands with a free-water surface.

CNS lymphatic drainage and neuroinflammation are regulated by meningeal lymphatic vasculature

open access: yesNature Neuroscience, 2018
Neuroinflammatory diseases, such as multiple sclerosis, are characterized by invasion of the brain by autoreactive T cells. The mechanism for how T cells acquire their encephalitogenic phenotype and trigger disease remains, however, unclear.

Chest Drainage [PDF]

open access: yesSeminars in Interventional Radiology, 2012
Infectious, traumatic, or neoplastic processes in the chest often result in fluid collections within the pleural, parenchymal, or mediastinal spaces. The same fundamental principles that guide drainages of the abdomen can be applied to the chest.

Foamed emulsion drainage: flow and trapping of drops [PDF]

open access: yes, 2017
Foamed emulsions are ubiquitous in our daily life but the ageing of such systems is still poorly understood. In this study we investigate foam drainage and measure the evolution of the gas, liquid and oil volume fractions inside the foam.

EROSIONAL DEVELOPMENT OF STREAMS AND THEIR DRAINAGE BASINS; HYDROPHYSICAL APPROACH TO QUANTITATIVE MORPHOLOGY

open access: yes, 1945
The composition of the stream system of a drainage basin can be expressed quantitatively in terms of stream order, drainage density, bifurcation ratio, and stream-length ratio. Stream orders are so chosen that the fingertip or unbranched tributaries are

Effect of saline drainage water on performance of denitrification bioreactors

open access: yesWater Supply, 2021
Excessive use of nitrate fertilizers in agriculture causes harm to humans and the environment. The most suitable nitrate removal process is heterotrophic biological denitrification.

Influence of drainage status on soil and water chemistry, litter decomposition and soil respiration in central Amazonian forests on sandy soils [PDF]

open access: yes, 2011
Central Amazonian rainforest landscape supports a mosaic of tall terra firme rainforest and ecotone campinarana, riparian and campina forests, reflecting topography-induced variations in soil, nutrient and drainage conditions.

Assessment of Climate Change Impacts on Agriculture of the Hashtgerd Plain with Emphasis of AR5 Models Uncertainty [PDF]

open access: yesعلوم و مهندسی آبیاری, 2018
Nowadays, in water resources management, climate change is one of the main challenges. Changes in the water cycle are one of the most important of ground responses to warming it (IPCC 2014).

Comparison of Some Split-window Algorithms to Estimate Land Surface Temperature from AVHRR Data in Southeastern Tehran, [PDF]

open access: yesDesert, 2009
Land surface temperature (LST) is a significant parameter for many applications. Many studies have proposedvarious algorithms, such as the split-window method, for retrieving surface temperatures from two spectrallyadjacent thermal infrared bands of ...
