Abstract:
In biological membranes that are permeable to water and ions but impermeable to other solutes, the diffusible ions cannot reach a concentration equilibrium. Instead, a state of electroneutrality is achieved on each side of the membrane, which requires that the diffusible ions be found in different concentrations on either side of the membrane. The Donnan equilibrium is a major contributing factor to the polarized state of cells, and appreciating it is vital to the understanding of neuronal physiology. This article presents a nonmathematical active-learning exercise that will help AP and college biology students understand how the Donnan equilibrium is achieved.

Moffat, Jeffrey C. "Properties of Conductance and Inhibition of Proton Channels: M2 from Influenza A Virus and Fo from Escherichia coli ATP Synthase." BYU ScholarsArchive, 2006. https://scholarsarchive.byu.edu/etd/479.

Full text
Abstract:
Proton channels are essential for many of the processes of life. The influenza A viral protein M2 is responsible for sensing the conditions necessary for viral RNA release. The proton-translocating FoF1 ATPase (ATP synthase) uses a proton gradient to drive adenosine triphosphate (ATP) synthesis. We have directly measured proton uptake in vesicles containing reconstituted M2 or FO by monitoring external pH after addition of valinomycin to vesicles with 100-fold diluted external [K+]. This proton flux assay was utilized to quantify proton flux through single M2 and Fo channels. Contrary to previous reports, proton uptake by M2 was not significantly altered by acidification of the extravesicular pH. We conclude that pH only weakly affects proton flux through M2 in the pH range of 5.4 - 7.0. Theoretical analysis utilized for such vesicle uptake assays illuminates the appropriate time scale of the initial slope and an important limitation that must be placed on inferences about channel ion selectivity. The rise in pH over 10 seconds after ionophore addition yielded time-averaged single channel conductances of 0.35±0.2 aS and 0.72±0.4 aS at pH 5.4 and 7.0 respectively. Such a low time-average conductance implies that M2 is only conductive 10^-6 to 10^-4 of the time. M2 selectivity for hydrogen over potassium is ~10^7. Fo translocates protons across membranes, converting electrochemical energy to rotational inertia. Previous experiments have been partially confounded by a contaminating channel, CL, which co-purifies with Fo and leaks cations. CL activity is shown to not decrease following deletion of the previously uncharacterized yraM open reading frame of E. coli. Fo purified from a deletion strain lacking yraM is just as active as Fo purified from the wild-type strain. Using Fo from the deletion strain, the single-hit hypothesis of DCCD inhibition of passive proton flux through Fo was examined. A DCCD-induced reduction in ATP synthase activity correlates with a reduction in the total initial slope, the number of functional Fo per µg protein, and the single channel proton flux. At least 2 DCCD per Fo are required to totally inactivate passive proton flux. M2 and Fo have similar single channel conductances but different open probabilities.

Abstract:
Acid/base and metal ion adsorption properties have been investigated for a range of chemically modified bleached Kraft fibre materials (pulps). The studies were performed via potentiometric titrations, Flame Atomic Absorbtion (and Emission) Spectroscopy, Inductively Coupled Plasma Optical Emission Spectroscopy and Extended X-ray Absorbtion Fine Structure measurements. As a result of a chemical modification procedure, the total concentration of acidic carboxylate groups in the fibre materials ranged between 43 and 590 μmol/g. The preferable surface potential model for modelling the ionic strength dependent acid/base properties of fibre materials with low charge densities, i.e. unmodified fully bleached Kraft fibre materials, was found to be the Basic Stern Model. For fibre materials with high total charge, ≳100 μmol/g, this model resulted in poor fits to data, and for such materials a number of Constant Capacitance Models, one at each ionic strength, must be recommended. With respect to metal ion adsorption, the results have indicated that the unspecific Donnan theory could correctly model the simultaneous adsorption of several metal ions, i.e. K+, Na+, Mg2+, Ca2+ and Cu2+, provided that the salt concentration in the fibre suspension is low. In suspensions of high salt concentration it was, however, found that this very same model strongly underestimated the adsorption of Ca2+ and Cu2+. Here, the Donnan model had to be complemented by specific ion exchange equilibria. These results were corroborated by spectroscopic evidence of specific interactions between Cu2+-ions and fibres. The spectroscopic indication of a complex formed between two fibre surface carboxylate groups and one Cu2+-ion, agree with the specific ion exchange model. It was therefore concluded that specific metal ionfibre interactions cannot be neglected, especially at high salt concentrations. The interactions occurring between the polycation GaO4Al12(OH)24(H2O)127+ and fibre materials were studied by both adsorption and spectroscopic measurements. These indicate that GaO4Al12(OH)24(H2O)127+ is surprisingly stable in fibre suspensions and that intact GaO4Al12(OH)24(H2O)127+- ions are strongly adsorbed onto the fibres. Also for this ion, specific interactions has to be considered, since the strong adsorption registered was too strong to be explained by Donnan equilibria. In the thesis, the stochiometric composition and an equilibrium constant characterising these interactions is presented.

We put the factor of pressure drop in the process of electrodialysis, and discuss the assumption of Donnan equilibrium in the interface of membrane and solution to influence the current efficiency. In this paper, we will discuss the fixed charges of linear and sinusoidal types. If we don't assume the Donnan equilibrium, current efficiency of linear type is higher than sinusoidal type of fixed charge in the condition of fixed total charges. If increasing the electrical potential drop, we found current efficiency increasing in the condition of fixed flow effect before some value of flow effect. But after some value of flow effect found current efficiency decreasing in the condition of fixed flow effect when increasing the electrical potential drop. The results of assuming Donnan equilibrium is the same as not assuming Donnan equilibrium qualitatively, but current efficiency is higher in the case of assuming Donnan equilibrium.

Abstract:
Con la Rivoluzione della Dignità (2014) un’ampia rappresentanza della popolazione dell’Ucraina si è pronunciata a favore di una collocazione geopolitica nell’UE e nella NATO. In parallelo, la Russia è intervenuta in Crimea e nel Donbas. La società ucraina, oltre ad affrontare le conseguenze di un conflitto e di una situazione geopolitica delicata, sta cercando un proprio equilibrio socio-politico interno, come dimostra l’avvicendamento Poroshenko-Zelens’kyj. La presente raccolta di studi, che coinvolge studiosi italiani, si concentra sui risvolti di carattere storico, giuridico, linguistico, culturale e religioso che accompagnano questo assestamento.

Questo volume raccoglie i migliori elaborati di tesi degli anni accademici 1999/00 e 2000/01 di studenti del Master Europeo in Scienze del Lavoro della Facoltà di Scienze Politiche "Cesare Alfieri" di Firenze. I contributi si concentrano sul tema del lavoro e della sua regolazione nei paesi europei, analizzando aspetti quali la flessibilità del lavoro, la formazione, le relazioni industriali aziendali, la responsabilità sociale delle imprese, la promozione della partecipazione al mercato del lavoro delle donne e dei disabili. Questi temi costituiscono dei punti di osservazione privilegiati per mettere in luce sia gli effetti di promozione del cambiamento del processo di integrazione politica europea sia il ruolo giocato dalla presenza di determinate architetture istituzionali relative ai sistemi di welfare, di regolazione dell'economia e del lavoro che continuano a essere differenti da paese a paese. Guardare a questa coesistenza tra stabilità e cambiamento con un approccio multidisciplinare e comparato come quello utilizzato nei lavori qui raccolti è come utilizzare un caleidoscopio che contribuisce a far luce sugli equilibri multipli e sui diversi percorsi di sviluppo che caratterizzano il cosiddetto "modello sociale europeo".

Abstract:
This chapter, “A Marriage of Mutual Convenience,” traces Callas’s marriage to Battista Meneghini, an affluent industrialist whom she met after arriving in Verona in 1947 to sing at the Arena amphitheater. During the twelve years they spent together, the couple became inseparable, with Battista fulfilling Maria’s dependency needs and Callas providing Meneghini, who became her manager, with a highly lucrative source of income and power. Throughout their marriage, Maria was grateful to Battista for launching her singing career. She found him a source of comfort and care. While projecting an image of a dutiful wife, Callas expected Meneghini to obey her wishes and desires, treating him as an extension of herself. Signs of disobedience were met with outbursts of anger and rage. Callas’s vocal problems disturbed the marital equilibrium. Meneghini’s insistence that she continued her career revived in Maria feelings that she was loved for her voice rather than for herself.

Abstract:
Processes in which charge is transferred from one phase to another at an interface make up an important class of interfacial reactions. Well-known examples are the reactions which occur at the electrodes of an electrochemical cell. These are electron transfer reactions, oxidation taking place at one electrode and reduction at the other. The early study of electrochemical cells provided valuable thermodynamic information about the redox processes occurring in them. When an electrochemical cell is a source of energy, for example, a battery, chemical energy is converted to electrical energy. When electrical energy is driven into an electrochemical cell from an external source, electrode reactions producing products of commercial interest are possible. Thus the general subject discussed here is of considerable practical importance. Another important class of interfacial charge transfer processes occurs at the membrane | solution interface. Some solute species can move into the membrane phase, whereas others cannot. When ions are involved in membrane selectivity, a potential drop is established at the interface. Ion transfer processes at membranes are extremely important in living organisms and form the basis for the functioning of the nervous system. Membranes are also involved in ion selective electrodes such as the ubiquitous pH electrode. These electrodes are often used in modern analytical techniques based on potentiometry. In the present chapter, the relationship between the electrode potential and the activity of the solution components in the cell is examined in detail. The connection between the Galvani potential difference at the electrode solution interface and the electrode potential on the standard redox scale is discussed. This leads to an examination of the extrathermodynamic assumption which allows one to define an absolute electrode potential. Ion transfer processes at the membrane | solution interface are then examined. Diffusion potentials within the membrane and the Donnan potentials at the interface are illustrated for both liquid and solid state membranes. Specific ion electrodes are described, and their various modes of sensing ion activities in an analyte solution discussed. The structure and type of membrane used are considered with respect to its selectivity to a particular ion over other ions.

Abstract:
In this study, electrokinetic transport in a micro-nanofluidic system is numerically investigated by solving the transient Poisson, Nernst-Planck, and Navier-Stokes equations simultaneously. The system considered is a nanochannel connected with two microchannels at its ends. Under various applied electric potential biases, the effect of concentration polarization on the fluid flow, induced pressure and electric current is examined. By comparing with the Donnan equilibrium condition and electroosmotic flow in microscale dimension, electric body force due to non-zero charge density is the mechanism for producing vortex flow and inducing positive pressure gradient in the anodic side of the system. The diffusive boundary layer thickness is reduced due to the stirring of the generated vortex flow and results in the over-limiting current when the applied electric potential bias is high.
