Nutrient/TOR signaling controls adipose mitochondrial transcription factor A (TFAM) to regulate organismal growth in Drosophila

FEBS Letters, EarlyView.
Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...

Are Phosphorous and Phosphoric Acids Equal Phosphorous Sources for Plant Growth?

EDIS, 2012
Phosphorus (P) is one of the 17 elements essential for plant growth and development, and is also a key component in some agrochemicals, such as phosphorous acid. Thus, there are two types of P closely associated with crop production.

Evaluation of the properties of complexing agent-collectors of eudialyte flotation [PDF]

Vestnik MGTU, 2015
Acid-based and complexing properties of reagent-collectors (carboxylic and hydroxamic acids, styrylphosphonic acid and dialkyl ether of phosphoric acid) for flotation of zirconium-containing minerals have been studied.

Influence of monoisodecyl phosphoric acid on extraction of neptunium with diisodecyl phosphoric acid. [PDF]

Journal of Nuclear Science and Technology, 1989
The influence of monoisodecy1 phosphoric acid (MIDPA) on the separation of Np with diisodecy1 phosphoric acid (DIDPA) was studied from the aspects of the extraction rate and the back-extraction with H2C2O4 solution. This study is important for the development of the partitioning method for high-level waste because MIDPA is one of the radiolysis ...

A minimal cellulosome‐like system in Cellulosilyticum lentocellum

FEBS Open Bio, EarlyView.
Cellulose‐degrading bacteria typically use cellulosomes, large multi‐enzyme complexes on a scaffold protein. In Cellulosilyticum lentocellum, we characterise a far smaller arrangement, a single scaffold bound to one cellulase through a single cohesin‐dockerin interaction.

Superlubricity and Corrosion Inhibition Properties of Solvate Ionic Liquids in Hybrid Carbon Fiber Reinforced Plastic–Steel Interfaces

Advanced Engineering Materials, EarlyView.
Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...

Corrosion Behaviour of the Anodic Oxide Film on Commercially Pure Titanium in NaCl Environment

International Journal of Electrochemical Science, 2014
Anodic oxide growths on commercially pure titanium in 1 M sulphuric and phosphoric acids have been investigated in the present study. Ruptures and blisters of the oxide layers were found as result of a huge pressure of oxygen bubbles developed within the
