Effect of Vinasse on Soil Acidity [PDF]
, 1987 The effects of microbiological activity on soil acidity components in soils previously treated with vinasse are determined. These soil acidity components were interpreted through the measurement of pH, exchangeable aluminium and titratable acidity.

The determination of exchangeable cations in acid soils: Errors caused by weathering reactions during neutral salt extraction [PDF]
, 1991 To investigate pH-controlled chemical reactions associated with the neutral salt measurement of exchangeable cations in acid soils, and to estimate the potential error caused by such reactions, a series of experiments was performed which modify an ...

Alleviating aluminum toxicity in an acid sulfate soil from Peninsular Malaysia by calcium silicate application [PDF]
Solid Earth, 2016 In response to human population increase, the utilization of acid sulfate soils for rice cultivation is one option for increasing production. The main problems associated with such soils are their low pH values and their associated high content of ...

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Revisiting Titration Procedures For The Determination Of Exchangeable Acidity And Exchangeable Aluminum In Soils [PDF]
, 2015 The use of 1 mol L-1 ammonium chloride (NH4Cl) or ammonium nitrate (NH4NO3) solutions as alternative soil extractants were evaluated for the determination of the exchangeable acidity and exchangeable aluminum (Al) in twelve soil samples by the ...

Ion-exchange Behavior of Acidic and Basic Amino Acids [PDF]
Bulletin of the Chemical Society of Japan, 1961 Abstract The ion-exchange behavior of the acidic and the basic amino acids was described and discussed. The maximum uptake of amino acids takes place in the pH range close to the iso-electric points and the pH effect is more remarkable and more characteristic, in comparison with the case of neutral amino acids.

FEBS Letters, EarlyView.Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Impacts of Choerospondias axillaris growth on acidity of Udic Ferrosols in subtropical China [PDF]
, 2005 Changes in acidity of Udic Ferrosols, caused by growth of Choerospondias axillaris (Roxb.) Burtt et Hill, in comparison to wild grass, were investigated for pH distribution in the soil profile, exchangeable acidity, and cation status in the soil leachate

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...
