Do we need intervention after pine tree removal? The use of different management techniques to enhance Cerrado natural regeneration
(2019-01-01)
Some Cerrado areas are suppressed by pine tree cultivation. These monoculture processes can exclude the fire presence and inhibit native species development. In Southeastern Brazil, thousands of hectares were planted with ...
Effect of hydraulic retention time on chemical oxygen demand and total nitrogen removal in intermittently aerated constructed wetlandsRemoção de DQO e Nitrogênio Total em alagados construídos com aeração intermitente em relação ao tempo de detenção hidráulica
(2020-01-01)
This study evaluated the effect of hydraulic retention time on chemical oxygen demand (COD) and total nitrogen (TN) removal in an intermittently aerated constructed wetlands. Two horizontal subsurface-flow constructed ...
Removable Partial Denture after Gunshot Injury: Five Year Follow-Up
(2017-06-01)
The aim of this study was to report a patient of rehabilitation with removable partial denture retained by implants in-patient who suffered injury after firearm shooting. A 19-year-old man presented to the hospital of the ...
Comparison of different strategies for nitrogen removal by simultaneous nitrification and denitrification process in a batch rotating disk reactor
(Natural State Research, Inc., 2017-10)
In this paper, different strategies of aeration and organics feed in the reactor were studied toevaluate the simultaneous nitrification and denitrification (SND) process efficiency for a sequencing batchrotating disk biofilm ...
Functional diversity revealed by removal experiments
(Elsevier Science London, 2003-03)
The dominant protocol to study the effects of plant diversity on ecosystem functioning has involved synthetically assembled communities, in which the experimental design determines species composition. By contrast, the ...
Copper, lead and cadmium removal by Ca Al layered double hydroxides
(Elsevier Science, 2014-01)
Layered double hydroxides are increasingly studied as heavy metal scavengers due to their acid/base buffering capacity that leads to hydroxide precipitation. Their intercalation with ligands such as edta also provides ...
Copper removal by Botryococcus braunii biomass with associated production of hydrocarbons
(Scitec Publications, 2013-10)
The goal of the present article is to evaluate the potential of copper(II) removal from acidic wastewater, associated with the production of hydrocarbons by the microalgae Botryococcus braunii. Results demonstrate that the ...
Spatial variation in post-dispersal seed removal in an Atlantic forest: Effects of habitat, location and guilds of seed predators
(Elsevier B.V., 2007-11-01)
Studies of post-dispersal seed removal in the Neotropics have rarely examined the magnitude of seed removal by different types of granivores. The relative impact of invertebrates, small rodents, and birds on seed removal ...
Poly(4-vinylbenzyl)trimethylammonium chloride) resin with removal properties for vanadium(v) and molybdenum(vi). A thermodynamic and kinetic study
(Journal of the Chilean Chemical Society, 2022)
Biomass Accumulation and Nutritional Requirements of Potato as Affected by Potassium Supply
(2020-09-01)
Potassium (K) supply affects the growth and tuber yield of potato (Solanum tuberosum L.) as well as the uptake and removal of certain nutrients. However, information on this is scarce or inconsistent. Thus, this study was ...
