The present study aimed to investigate the effects of root surface iron plaque on the uptake kinetics of arsenite and arsenate by excised roots of rice (Oryza sativa) seedlings. The results demonstrated that the presence of iron plaque enhanced arsenite and decreased arsenate uptake. Arsenite and arsenate uptake kinetics were adequately fitted by the Michaelis-Menten function in the absence of ...

Human mesenchymal stem cells (hMSCs) from the bone marrow represent a potential source of pluripotent cells for autologous bone tissue engineering. We previously discovered that over activation of the Wnt signal transduction pathway by either lithium or Wnt3A stimulates hMSC proliferation while retaining pluripotency. Release of Wnt3A or lithium from porous calcium phosphate scaffolds, which we...

Using the recently developed Cahn-Hilliard reaction (CHR) theory, we present a simple mathematical model of the transition from solid-solution radial diffusion to two-phase shrinking-core dynamics during ion intercalation in a spherical solid particle. This general approach extends previous Li-ion battery models, which either neglect phase separation or postulate a spherical shrinking-core phas...

A new phosphate-binding agent which does not cause any severe side effects in vivo was developed by modifying a crosslinked dextran with polynuclear iron(III)oxide-hydroxide. Its particle size ranges from 150 to 300 microns, and the iron content was about 18% by dry weight. The oxidation state of iron was characterized by ESCA and Mössbauer spectroscopy. The maximum phosphate binding capacity o...

information about forms of phosphorus (p) is important for the evaluation of p status in soil and also understanding of the soil fertility and plant nutrition. to obtain such information and to determine the relationship between the p forms from soil characteristics, amount of different organic and inorganic p forms of 20 soil composite samples of eastern azerbaijan province, iran were determin...

A good cooling inside a battery pack is important to avoid safety issues and avoid the development of too large internal temperature gradients. The temperature distributions inside two packs (in-line and staggered) made of large cylindrical lithium iron phosphate cells (of 18 Ah nominal capacity) are analysed in this paper during a 90 A constant discharge current. The analysis of the battery pa...

The battery State of Charge (SoC) is critical information to overcome agricultural robots’ limitations related and energy management. Although several SoC estimation methods have been proposed in the literature, performance these has not validated for different chemistries mobile robot applications. Compared previous work, this paper evaluates limits using RC model Thevenin a Lithium Iron Phosp...

This publication will present best practices for incremental capacity analysis, a technique whose popularity is growing year by because of its ability to identify battery degradation modes diagnosis and prognosis. While not complicated in principles, the analysis can often feel overwhelming newcomers contradictory information introduced ill-analyzed datasets. work aims summarize centralize good...

Summary The state‐of‐charge (SOC) of the battery is most critical parameter for an electric vehicle (EV) dashboard. Generally, Coulomb counting (CC) method used SOC estimation, but conventional CC has some errors due to initial determination. This work uses modeling and estimation a lithium‐iron‐phosphate (LFP) determine SOC. equivalent circuit models (ECMs) have been parameters by least‐square...
