Tree pruning is a management tool in agroforestry systems for reducing shade, enhancing nutrient cycling or providing fodder. However, little information is available on the effect of pruning manageme...
Reducing reliance on nitrogen fertilizers via biological nitrogen fixation（图）
reliance nitrogen fertilizers biological nitrogen fixation
2020/4/3
Crop yields have increased substantially over past decades, along with increasing use of nitrogen fertilizer. While nitrogen fertilizer benefits crop growth, it has negative effects on the environment...

Potassium fixation in soil size fractions of arid soils
calcareous soils Iran smectite soil fractionation
2015/3/9
Amounts of potassium (K) fixed in soil fractions of 10 calcareous soils of southern Iran were measured to evaluate the contributions of different soil size fractions to K fixation. Soil particles were...
Assessing nonpoint-source nitrogen loading and nitrogen fixation in lakes using δ15N and nutrient stoichiometry
Assessing nonpoint-source nitrogen loading nitrogen fixation lakes using δ15N nutrient stoichiometry
2014/4/3
Runoff from human-dominated watersheds has greatly altered nitrogen (N) and phosphorus (P) cycling in lakes. Nutrients from human sources are distinct from those from undisturbed ecosystems in several...
Nickel limitation of nitrogen fixation inTrichodesmium
Nickel limitation nitrogen fixation Trichodesmium
2014/4/2
I show that the growth ofTrichodesmium, the primary diazotrophic phytoplankton in tropical and subtropical oceans, can be limited by Ni availability in both trace metal–defined culture media and natur...
Advective transport of diazotrophs and importance of their nitrogen fixation on new and primary production in the western Pacific warm pool
Advective transport diazotrophs importance their nitrogen fixation new primary production in the western Pacific warm pool
2014/4/2
The western Pacific warm pool (WPWP) is a region of low nutrient and chlorophyll concentrations in which new production is generally considered to be supported by upward fluxes of nitrate from the dee...
Diversity trumps acidification: Lack of evidence for carbon dioxide enhancement of Trichodesmiumcommunity nitrogen or carbon fixation at Station ALOHA
Diversity trumps acidification Lack of evidence carbon dioxide enhancement Trichodesmiumcommunity nitrogen carbon fixation Station ALOHA
2014/4/2
We conducted 11 independent short-term carbon dioxide (CO2) manipulation experiments using colonies of the filamentous cyanobacteria Trichodesmiumisolated on three cruises in the North Pacific Subtrop...
Evaluation of Fixation Disparity Curve Parameters With the Modified Near Mallett Unit in Symptomatic and Asymptomatic University Students
Fixation Disparity Visual Symptoms Binocular Vision
2015/10/9
Background: Research suggests that fixation disparity data are extremely useful in the assessment of the binocular and accommodative systems.
Ammonium uptake and dinitrogen fixation by the unicellular nanocyanobacterium Crocosphaera watsonii in nitrogen-limited continuous cultures
nanocyanobacterium Crocosphaera Ammonium uptake
2014/4/2
Ammonium uptake and nitrogen (N) fixation of the unicellular nanocyanobacterium Crocosphaera watsonii
isolated from the western subtropical North Pacific were determined in N-limited continuous cultu...
Iron, phosphorus, and nitrogen supply ratios define the biogeography of nitrogen fixation
Iron phosphorus nitrogen fixation
2014/4/2
We present a unified conceptual framework describing the competition between diazotrophs and non–
nitrogen-fixing marine plankton and their interaction with three essential nutrient elements: nitroge...
Study of Mechanism of the W-OH Sand Fixation
W-OH Sand Fixation Adhesive Force Porosity Solidifying Time Wind Tunnel Test
2013/3/11
A novel hydrophilic polyurethane (abbreviated as W-OH) was developed and applied as a sustainable sand-fixing material. This paper on the chemical sand fixation mechanism of W-OH discusses the adhesiv...

Whenever eye movements are measured, a central part of the analysis has to do withwheresubjects fixate, andwhy they fixated where they fixated. To a first approximation, a set of fixations can be view...
Predicting Fixation Tendencies of the H3N2 Influenza Virus by Free Energy Calculation
Fixation Tendencies of the H3N2 Influenza Virus Free Energy Calculation Biomolecules
2012/5/2
Influenza virus evolves to escape from immune system antibodies that bind to it. We used free energy calculations with Einstein crystals as reference states to calculate the difference of antibody bin...
