Energy Potential Mapping: Open Data in Support of Urban Transition Planning
Authors: Fremouw Michiel , Bagaini Annamaria , De Pascali Paolo
Published: March 2020

Cities play a key role in driving the transition to sustainable energy. Urban areas represent between 60% and 80% of global energy consumption and are a significant source of CO2 emissions, making energy management at the urban scale an important area of research. Urban energy systems have a strong influence on the environment, economy, social dimensions and urban spatial planning. Energy consumption affects the urban microclimate, urban comfort, human health, and conversely, urban physical, economic and social characteristics affect the energy urban profile. In order to improve the quality of energy strategies, policies, and plans, local authorities need decision support tools, like energy potential mapping, which have risen significance in the last decades. Energy data are crucial for those tools. They can increase the quality and effectiveness of energy planning but also support the integration between energy and spatial planning. Energy data can also stimulate citizen engagement as well as encourage sustainable behaviours and CO2 emission reduction. This paper aims to increase the practice of data-aware planning, through the study of problems in energy data acquisition and processing observed in European projects focused on developing energy mapping tools. The problems observed attend to two main areas: technical and socio-economic issues. Those were derived from a comparison of energy mapping tools, and the work conducted for the PLANHEAT development. The scope of the research is to understand the main recurring issues in energy data acquisition and processing, in order to overcome the barriers in data availability. Increasing awareness of the relevance of energy data can foster the use of energy mapping tools, increasing the quality of energy policies and planning.

Published: March 2020

Backfill mining is the most environmentally friendly mining method at present, which can effectively control the surface subsidence, improve the recovery rate, and has good social and economic benefits. The purpose of this study is to solve the environmental problems caused by solid waste, combined with the rich geographical advantages of aeolian sand in the Yushenfu mining area of China. The rheological properties of the aeolian sand-fly ash-based filling slurry with different fly ash content are studied by experiments, and the strength development law of the filling body under different age and fly ash content are studied from the macroscopic and microscopic points of view. The rheological experiments showed that the increase of the amount of fly ash has a significant effect on the thixotropy, plastic viscosity, and yield stress of the filling slurry. Additionally, rheological properties of aeolian sand-fly ash-based filling slurry conform to the Bingham model. With the increase of the amount of fly ash, the performance of the filling slurry has been significantly improved. Uniaxial test and scanning electron microscope observation showed that the influence of fly ash on the strength of the filling body was mainly reflected in the late stage of maintenance, but was not obvious in the middle stage. Fly ash particles mainly bear the role of “water reduction” and a physical filling effect, which makes the filling slurry thicker and the internal structure more closely spaced. The volcanic ash reaction of fly ash is lagging behind the hydration reaction of cement; the secondary product of the delayed reaction is filled in the pores of cement hydrates, which can greatly reduce the porosity of the backfill body and increase the later strength of the backfill body. It provides a guarantee for the safe replacement of coal pillars in the working face.

Published: March 2020

In the next decade, due to the desire for significant reduction in the carbon footprint left by the aviation sector and the development of a sustainable alternatives to petroleum, fuel from renewable sources will play an increasing role as a propellant for turbine aircraft engines. Currently, apart from five types of jet fuel containing synthesized hydrocarbons that are certified by the ASTM D7566 standard, there is yet another synthetic blending component that is at the stage of testing and certification. Hydroprocessed esters and fatty acids enable the production of a synthetic component for jet fuel from any form of native fat or oil. Used feedstock affects the final synthetic blending component composition and consequently the properties of the blend for jet fuel and, as a result, the operation of turbine engines. A specialized laboratory test rig with a miniature turbojet engine was used for research, which is an interesting alternative to complex and expensive tests with full scale turbine engines. The results of this study revealed the differences in the parameters of engine performance and emission characteristics between tested fuels with synthetic blending components and neat jet fuel. The synthetic blending component was obtained from two different feedstock. Noticeable changes were obtained for fuel consumption, CO and NOx emissions. With the addition of the hydroprocessed esters and fatty acids (HEFA) component, the fuel consumption and CO emissions decrease. The opposite trend was observed for NOx emission. The tests presented in this article are a continuation of the authors’ research area related to alternative fuels for aviation.

Authors: Rajapakse Gimara , Jayasinghe Shantha , Fleming Alan
Published: March 2020

Oscillating water column wave energy converter arrays can be arranged to enhance the energy production and quality of power delivered to the grid. This study investigates four different array configurations of vented oscillating water columns and their effect on power quality and capacity of the energy storage systems required to absorb power fluctuation. Configuring the array of vented oscillating water columns as a nearshore detached breakwater allows combining the benefits of their complementary features. This increases the economic optimization of wave energy converters, paving the path to the energy market. The operations of the integration schemes are evaluated using the results obtained from simulations carried out using MATLAB/Simulink software. Simulation results show that the array of vented oscillating water columns and array of vented oscillating water columns as nearshore detached breakwater configurations increase the quality of power delivered to the grid and reduce the capacity of the energy storage systems required.
Defects and Dopants in CaFeSi2O6: Classical and DFT Simulations
Authors: Kuganathan Navaratnarajah , Chroneos Alexander
Published: March 2020

Calcium (Ca)-bearing minerals are of interest for the design of electrode materials required for rechargeable Ca-ion batteries. Here we use classical simulations to examine defect, dopant and transport properties of CaFeSi2O6. The formation of Ca-iron (Fe) anti-site defects is found to be the lowest energy process (0.42 eV/defect). The Oxygen and Calcium Frenkel energies are 2.87 eV/defect and 4.96 eV/defect respectively suggesting that these defects are not significant especially the Ca Frenkel. Reaction energy for the loss of CaO via CaO Schottky is 2.97 eV/defect suggesting that this process requires moderate temperature. Calculated activation energy of Ca-ion migration in this material is high (>4 eV), inferring very slow ionic conductivity. However, we suggest a strategy to introduce additional Ca2+ ions in the lattice by doping trivalent dopants on the Si site in order to enhance the capacity and ion diffusion and it is calculated that Al3+ is the favourable dopant for this process. Formation of Ca vacancies required for the CaO Schottky can be facilitated by doping of gallium (Ga) on the Fe site. The electronic structures of favourable dopants were calculated using density functional theory (DFT).

Authors: Vahabzadeh Alireza , Kasaeian Alibakhsh , Monsef Hasan , Aslani Alireza
Published: March 2020

This study proposes a fuzzy self-organized neural networks (SOM) model for detecting fraud by domestic customers, the major cause of non-technical losses in power distribution networks. Using a bottom-up approach, normal behavior patterns of household loads with and without photovoltaic (PV) sources are determined as normal behavior. Customers suspected of energy theft are distinguished by calculating the anomaly index of each subscriber. The bottom-up method used is validated using measurement data of a real network. The performance of the algorithm in detecting fraud in old electromagnetic meters is evaluated and verified. Types of energy theft methods are introduced in smart meters. The proposed algorithm is tested and evaluated to detect fraud in smart meters also.

Farming systems need to be planned to provide suitable levels of economic profitability and, at the same time, ensure an effective energy use, in order to perform environmentally friendly production strategies. The herein present work aims to assess the efficiency of energy use and economic impacts of the main farming methods (conventional, organic and integrated) of Clementine’s crops in Calabria (South Italy), through a combined use of Life Cycle Energy Assessment (LCEA) approach and economic analysis. For this purpose, data were collected from clementine producers by using face-to-face interviews. The results revealed that average energy consumption in the organic farming systems was 72,739 MJ, lower than conventional and integrated systems equal to 95,848 MJ and 94,060 MJ, respectively. This is mainly due to the ban of chemicals. Economic analysis showed that organic farms were more profitable compared with the other farming methods, because of the greater selling price and the EU economic support, reaching an average net profit of 4255 € ha−1 against 3134 € ha−1 of integrated farms and 2788 € ha−1 of conventional ones. The economic efficiency of energy from clementine production was 0.058 € MJ−1 in the organic farming, higher compared to the other two farming systems equal to 0.033 € MJ−1 on average.

Published: March 2020

The paper presents the results of a study on chemical composition of ashes from three types of waste biomass in terms of fertilizer usefulness. Waste from the process of corn grain drying, including corn cobs, corn grains and corn husk and their mixtures in the ratio 4:1 (v/v) were examined. The study proved that corn grain was the material with the highest concentration of macroelements among those studied (P—21,452 ppm, K—25,970 ppm, S—5911 ppm) and the mixture of corn cobs with corn grains (Ca—81,521 ppm). When microelements were considered, the highest concentration was recorded for corn cobs (Cu—207 ppm, Mn—844 ppm, Zn—857 ppm) and corn husk (Fe—15,100 ppm). The analysis of toxic elements in the ashes of the biomass studied showed their highest concentration in corn husk ash (Ni—494 ppm, Cr—301 ppm, Pb—42.7 ppm, As—4.62 ppm). The analysis showed that regardless of the type of biomass studied, all ashes were strongly enriched (in relation to the average soil content) with phosphorus and corn husk ash with calcium in particular. A slight enrichment in copper and lead was recorded for all ashes, and moderate or low for the other elements. It was found that the examined ashes from biomass, which is a residue from the drying of maize grain, have a high fertilizer usefulness.

Published: March 2020

Higher-voltage-standard and higher-power-rating aerospace power systems are being investigated intensively in the aerospace industry to address challenges in terms of improving emissions, fuel economy, and also cost. Multilevel converter topologies become attractive because of their higher efficiency under high-voltage and high-switching-frequency conditions. In this paper, an asymmetrical-voltage-level back-to-back multilevel converter is proposed, which consists of a five-level (5L) rectifier stage and a three-level (3L) inverter stage. Based on the comparison, such an asymmetrical back-to-back structure can achieve high efficiency and minimize the converter weight on both rectifier and inverter sides. A compact triple-surface-mounted heatsink structure is designed to realize high density and manufacturable thermal management. This topology and structure are evaluated with a full-rating prototype. According to the evaluation, the achieved power density is 2.61 kVA/kg, which is 30% higher than that of traditional solutions. The efficiency at the rated power of the back-to-back system is 95.8%.

Gramsci and The South as a Space of Emancipation
Authors: Fontana Antonio
Published: March 2020

The paper will actively engage with the contradictions found in Gramsci in an attempt to tease out the elements of emancipation found in his thought, as well as a sub-culture of opposition against Western notions of rationality. Antonio Gramsci’s analysis of the Italian South and of the Southern Italian peasantry in relation to the formation of a radical politics of emancipation constitutes one of the most salient features of his critique of orthodox Marxism. I argue that for the Italian Marxist theorist, the liberation of the Italian peasantry is not only a project of social, economic and political emancipation. Rather, the peasantry’s emancipation is also seen as a project of cultural liberation, a liberation from the dominant strands of rationalist and positivist Enlightenment thought, which Gramsci saw as encapsulated in Crocean philosophy. For Gramsci, the task of the organic intellectuals is to create an ideational sphere in which the colonized South can potentially articulate and celebrate a culture that has historically been deemed backward and primitive. However, Gramsci’s analyses of the South also contain historicist encrustations, which create a dialectical tension in his theory of politico-cultural emancipation that has never really been solved. I argue that the positivist and progressionist encrustations of Gramsci’s program for the emancipation of the South is an instantiation of a wider, Western, 19th and 20th century intellectual tradition which conflates “progress” as such with emancipation, a tradition that goes beyond the Italian and European context, and that is even paralleled by the model for black emancipation in the American South put forth by a figure as seemingly divergent as, say, W.E. B. Du Bois in the The Souls of Black Folk (1903).
Sardegna tra leggenda e realtà: ‘Sa femmina accabadora’, colei che dà la buona morte, nelle immagini e nelle parole di alcuni autori sardi
Authors: Murgia Gisella
Published: March 2020

The term accabadora refers to a woman entrusted with the task of facilitating the passing of the dying people. She killed for pity, called by the families of the patients to relieve their sufferings on their own deathbed. Basically, she practiced a sort of ante litteram euthanasia. But that carried out by the woman was also a necessary action for the survival of relatives who, most of the time, did not have the necessary resources to alleviate the sufferings of the kinsmen. Furthermore, in small towns, the doctor was often several days away on horseback. While the accabadora took life away, on the other hand, she gave it back, helping the women of her community to give birth. Everyone in the village knew the activity of these women but all of them were silent. They were convinced that the work of the accabadora was a meritorious work because it took the burden of putting an end to the sufferings of the patient. They implicitly recognized in it a social utility. After outlining the figure of 'sa fèmmina practica', this report analyses some works by Sardinian authors who are interested in it. Above all, we will mention the novel by Michela Murgia, Accabadora (Campiello prize 2010); the film by Enrico Pau, L'accabadora; the novels L’ultima agabbadòra by Sebastiano Depperu and L'agabbadora. La morte invocata by Giovanni Murineddu; the short film Deu ci sia by Gianluca Tarditi, winner of the 2011 Golden Globe at 48th New York Film Festival; Ho visto agire s’accabadora by Dolores Turchi; Eutanasia ante litteram in Sardegna. Sa femmina accabadora by Alessandro Bucarelli and Carlo Lubrano and S’accabadora e la sacralità del femminino of Maria Antonella Arras.
The Last Mother: From Enrico Pau’s L’accabadora (2015) to Valeria Golino’s Miele (2013)
Authors: Luciano Bernadette
Published: March 2020

L'accabadora, is a Sardinian term deriving from the Spanish word 'acabar' which means to finish or complete. It refers to a female figure in Sardinian popular tradition, 'the last mother', an angel of mercy who assists the terminally ill in leaving the world. In this paper I explore variations of this female figure in two contemporary films. Enrico Pau's film L'accabadora set in pre- and World War II Sardinia, revolves around a protagonist (Annetta) who is a direct descendant of this Sardinian tradition. The second film, Valerio Golino's Miele, proposes what might be considered a contemporary variant of the Sardinian folk figure. While the tabu subject of euthanasia certainly forms the backdrop to the films, what is foregrounded is the isolation and alienation of the female protagonists who carry out care-giving roles tied to death. Torn between the conviction that the tasks they perform as “last mothers” console or provide final moments of serenity to the dying and an intangible discomfort with their execution of the task, they remain seemingly haunted by their roles, exhibiting an unease that arises from societal discomfort with administering death and a profession that requires that they direct their care to the dying rather than to the living. The representation of the films’ protagonists, their framing and the construction of the journeys they undertake, turn both films into narratives of self-discovery, motivated by encounters with others and otherness, and visually configured by the physical mobility across transformed geo-political landscapes that is central to the films.
Per una grammatica del sogno nel «Decameron». Forme e strutture delle novelle a tema onirico
Authors: Artico Tancredi
Published: March 2020

This paper takes into account the oneiric issue in Giovanni Boccaccio Decameron, with the aim of defining Boccaccio’s overall “grammar of dreaming”: besides an accurate investigation on Decameron’s sources, which range from classic to Medieval literature, it retraces the narrative constructions of the short-novels with oneiric subjects, hypothesizing the existence of two main schemes. In the short-tales on a vision (which are the most known), it is almost always replied the scheme of the “tale in the tale”, due to the creation of a imaginary world with its own rules. Meanwhile, in the short tales of deceiving, the dream is useful to trick the naive antagonist, making him believe something unbelievable. In both cases, it has a deep influence on the so-called “statute of reality” (Amedeo Quondam): in the first, there is the invention of a new reality; in the second it is deconstructed instead.
Goliarda Sapienza atipica “giornalista militante”
Authors: Trevisan Alessandra
Published: March 2020

This paper retraces Goliarda Sapienza’s no-fiction production between 1981 and 1988, considering in particular two feminist reviews of that period such as «Quotidiano Donna» and «Minerva: l’altra metà dell’informazione» on which she wrote articles about society, most of them never considered before today. Excluding the topic of the prison in her most important novels L’università di Rebibbia (1983) and Le certezze del dubbio (1987), the 80s could be defined as a moment of experience inside and beyond the Italian political context. Her reflections on Feminism authorize an interpretation of her “anomalous” way of thinking. At the end, the need to belong to a group will also open the following season.

L'esempio di Silvio Trentin
Authors: Bobbio Norberto
Published: March 2020

Using unpublished documents, this volume restores the meeting between two masters in a historical and ideal way: Norberto Bobbio and Silvio Trentin. Through the writings which Bobbio dedicated to Trentin between 1954 and 1991, the readers are introduced to Trentin’s world. They gradually discover Trentin’s exemplary biography, his clear moral personality and his commitment to anti-fascism and the Resistance, as well as the great themes of his work as a jurist and political thinker: the criticism of fascism, federalism and the idea of the 'third way'. As Bobbio observes, the fundamental reason why Trentin represents a still valuable example is that, through his life and thought, he has perfectly embodied the conception of politics as a desire of justice, as opposed to the will to dominate.

The Ground-Motion Attenuation Comparison: A case study for the 2017/05/11 Askale earthquake (Mw4.7)
Authors: Bayrak Erdem
Published: March 2020

Turkey is located on the Mediterranean-Himalayan seismic belt, which is the second largest earthquake zone in the world. Due to the fact that Erzurum basin is located in the Eastern Anatolia Region, it has a very complex structure in terms of its geological, tectonic and morphological features. Erzurum has been affected by destructive earthquakes throughout history. Some of these are Erzincan earthquake (26 December 1939), Horasan-Narman earthquake (30 October 1983), Spitak-Armenia earthquake (7 December 1988). In this study, the acceleration data of Erzurum-Aşkale (Mw=4.7) was used in order to estimate the peak ground acceleration using attenuation relationships. Attenuation relationships are important to determine how the peak ground acceleration decreases with distance. The data was recorded at twenty accelerometers in and around Erzurum. Peak ground accelerations were estimated according to Sadigh et al. (1997), Ambraseys et al. (1996), Kalkan and Gülkan (2004) attenuation relationships. As a result of calculations and comparisons, attenuation relationship of Sadigh et al. (1997) has found to be appropriate to the acceleration values recorded in the stations and has given the best results for the different soil types.
Influence of Composition, Concentration and Temperature of some Biological Liquids upon the Corrosion Behaviour of Titanum
Authors: Popescu Rodica , Ionita Daniela , Minculescu Florin
Published: March 2020

In order to investigate the corrosion behaviour of titan in aqueous solutions of lactic acid (1, 3 and 4% w) and albumin (2 and 10 % w) the cyclic polarization curves in potentiodynamic conditions were used. The corrosion parameters were estimated and their values were discussed as a function of acid lactic and albumin concentration and temperature. The stability of titan in investigated biological liquids was interpreted by involvment of the adsorption of either lactic acid or albumin onto the passive layer, a process which is favorised by moderate temperatures (as 370C � the human body temperature) as well as by low concentrations of lactic acid and albumin, respectively.

3,5-disubstituted-1,2,4-tiadiazoles with substituted-styril and heterocycle-vinyl were obtained by extending the method which implies the use of 3,5-disubstituted-1,2,4-ditiazolium salts as precursors [1-4]. A comparative study of the reaction process in the case of perchlorates, diacide phosphates, tribromides and 3,5-distyrile-dithiazolium triiodides, taken as etalon, was perfomed. Good yields were obtained when using perchlorates, phosphates and triiodides. The reaction was made by heating the reaction mixture and by ultrasound exposure. The structure of the compounds was confirmed by chemical and physical analysis and the data obtained were identical to those of 3,5-disubstituted-1,2,4-tiadiazoles obtained by another methods [5,6]. The biological (antibacterial and anticancer) activity of the synthesized compounds was tested and the results indicated a medium activity.

The aim of this paper is to study the use of a mixture of commercial clay namely K10 and a natural Romanian sodium bentonite in the adsorption of NH3 contained in air using fixed and fluidized bed gas-solid reactors. Qualitative (DRX) and quantitative (XPS, DTG) analysis were performed. Clays were agglomerated and treated with NH3. Adsorption isotherms were determined under several operating conditions. Results showed that after 70 minutes of ammonization, activated agglomerated clay exhibits a superior capacity of adsorption (2.09 mmoles NH3/g clay instead of 1.057 mmoles/g clay for natural clay). The saturation duration depends on the adsorbent bed state (fixed or fluidized bed). The mass transfer is better in fluidized bed, the clay layer being saturated more rapidly compared to the fixed bed.

The European laws and recently the Romanian ones impose more and more strict norms to the large nitrogen dioxide polluters. They are obligated to continuously improve the installations and products so that they limit and reduce the nitrogen dioxide pollution, because it has negative effects on the human health and environment. In this paper are presented these researches made within a case study for the Timi�oara municipality, regarding the modeling and simulation of the nitrogen dioxide dispersion phenomenon coming from various sources in atmosphere with the help of analytical-experimental methods. The mathematical model resulting from these researches is accurately enough to describe the real situation. This was confirmed by comparing the results obtained based on the model with real experimental values.

Authors: Siminiceanu Ilie , Dragan Mihaela , Friedl Anton , Harasek Michael
Published: March 2020

The effective mass transfer area of a Mellapak 750 Y structured packing was measured in a bench- scale plant with a column having an internal diameter of 100mm, and a packing height of 518 mm, using a broad range of gas and liquid flow rates. The absorption of carbon dioxide into natrium hydroxide aqueous solutions of 0.5 and 1.0 mol/L has been employed as test reaction. The validity of data obtained was tested by checking the two conditions of fast pseudo first order irreversible reaction. The data have been correlated by a criterial equation giving the ratio between the effective and the geometric areas versus the Reynolds number of the liquid phase. The coefficients of the equation have been identified by regression.

Published: March 2020

In a preceding study, the molecular hydrophobicity (RM0) was determined experimentally from reverse-phase thin-layer chromatography data for several substituted phenols and 2-(aryloxy-a-acetyl)-phenoxathiin derivatives, obtained from the corresponding phenoxides and 2-(a-bromoacetyl)-phenoxathiin. QSPR correlations for RM0 were explored using four calculated molecular descriptors: the water solubility parameter (log Sw), log P, the Gibbs energy of formation (DGf), and the aromaticity index (HOMA). Triparametric correlations do not improve substantially the biparametric correlation of RM0 in terms of log Sw and HOMA.

A theoretical study of the effect of variable viscosity on the steady free convection flow in a horizontal infinite porous channel when a part of its bottom wall is heated is presented in this paper. The transformed equations are solved numerically using a finite-difference method. The effects of the Rayleigh number and viscosity parameter on the flow and heat transfer characteristics are discussed.
The structure of [Cu(bipy)3][Cu(bipy)(ala)(ClO4)2]ClO4 � a Compound with Two Different Coordination Modes in the same Complex
Authors: Braban Mircea , Haiduc Ionel
Published: March 2020

The paper describes the solid state structure of a compound of composition [Cu(bipy)3][Cu(bipy)(ala) (ClO4)2]ClO4, in which both the cation and anion are octahedral complex species with copper(II) as coordination center. The cation contains three chelate rings formed by bipy; the anion contains in the quatorial plane a CuONC2 chelate ring formed by the alaninato ligand and a CuN2C2 chelate ring formed by bipy, with two monodentate perchorato ligands in axial positions completing the six-coordination. In the crystal p-p stackings lead to a supramolecular self-assembled structure.

Authors: Tomoaia-Cotisel Maria , Mocanu Aurora
Published: March 2020

The phase behaviour and surface structure of dipalmitoyl phosphatidyl choline (DPPC) monolayers at the air/water interface, in the absence and the presence of procaine, have been investigated by Langmuir-Blodgett (LB) technique and atomic force microscopy. The LB films were transferred on mica, at a controlled surface pressure, characteristic for the expanded liquid to condensed liquid phase transition of pure DPPC monolayers. The results indicate that procaine penetrates into and specifically interacts with phospholipid monolayers stabilizing the lipid membrane interface.

Authors: Cecal Alexandru , Ionic� Florica , Popa Karin
Published: March 2020

This paper deals with an approach of the investigation of the corrosion reactions, which is based on the absorption of b rays emitted by Tl-204 radionuclide by the iron ions, which pass into the aggressive solution through anodic dissolution of a metal sample. There can be noticed a decreassing of the activity b rays, reduction which is measured while the concentration of the iron ions in the corrosive solution increases. Out of the experimental data, there can be calculated the constant of the global corrosion rate, which accurately characterizes the development of this complex process. There was experimentally investigated the corrosion of three types of steel: H-12, MoCN-15 and W-85 in aggressive media of HCl and NaCl solutions.The values of the global rate constants vary depending on the steel composition and the corrosion medium.
Theoretical Analysis of Hydrogen Bonding in the Active Site of Bovine Rhodopsin
Authors: Bondar Ana-Nicoleta , Sugihara Minoru
Published: March 2020

The retinal binding pocket of bovine rhodopsin contains an extended hydrogen-bonded network that involves protein amino acids and water molecules. The protonation state and the role of Glu181, which is part of the hydrogen-bonded network, have been debated. According to the counterion switch model, Glu181 is protonated in the rhodopsin state and it becomes negatively charged (and a counterion for the protonated retinal Schiff base) in Meta II, upon proton transfer to Glu113[24, 25]. In contrast, in the complex counterion model Glu181 is negatively charged in rhodopsin, and the role of counterion is gradually shifted from Glu113 to Glu181 during activation [13]. Here we perform computer simulations to examine the energetics of a putative proton transfer path from Glu181 to the counterion of the retinal Schiff base, Glu113, in the rhodopsin and bathorhodopsin intermediates. The calculated energy barriers and reaction energies are significant. This suggests that proton transfer from Glu181 to Glu113 is very unlikely in the rhodopsin and bathorohodopsin protein structures.

The rock layers from above the cavity are slowly crossed, through micro cracks, by the rain water. The rain water arrives on the cavity wall as a concentrated solution with a high acidity level (pH 1-1.5). The percolating acid solution is crowded by acidophilic microorganisms with a dominating population of chemo-autotrophic bacteria Acidithiobacillus ferrooxidans provides the primary organic substance by oxidation of pyrite from the cavity walls and with six strains of Penicillium representing the heterotrophic organisms that use the organic substance from the primary producer. Between the A. ferrooxidans population and the Penicillium strain populations a close trophic relationship is established and the microorganisms number depends on the acid solution concentration. The ferric hydroxide formed through the oxidation of pyrite by A. ferrooxidans is deposed at the Penicillium hyphae exterior and forms minerals structures.

Published: March 2020

The aim of the present paper was the synthesis and chemical characterization of some original compounds with dibenzo[b,e]thiepine structure. The synthesis of the new compounds was performed in several stages. Thus, by reaction of phtalide with thiophenol potassium salt, we obtained the 2-phenylthiomethyl-benzoic acid. The acid was cyclized with polyphosphoric acid to the desired 6,11-dihydrodibenzo[b,e]thiepin-11(6H)-one, converted afterwards to the corresponding oxime and subsequently to the O-acyloximino-dibenzo[b,e]thiepins by acylation with various substituted benzoic acid chlorides. The oxidation of O-acyloximino-dibenzo[b,e]thiepins with hydrogen peroxide afforded the corresponding sulfones. The new compounds, four O-acyl-oximino-dibenzo[b,e]thiepins, and four O-acyl-oximino-dibenzo[b,e]thiepin-5,5-dioxides, have been characterized by their physical constants (melting point, solubility) and their structures and purity were confirmed by elemental analysis, and spectral analysis (IR, 1H-NMR, 13C-NMR).

Electrochemical deposition of polytyramine (PTy) was performed by cyclic voltammetry and it was observed that, in acidic media, 20 to 50 consecutive deposition cycles allowed us to obtain polymer coatings with good conductivity and high porosity. The polytyramine layers were used as a matrix for electrochemical deposition of platinum and the electrocatalytic activity for methanol oxidation of the composite material thus obtained was put in evidence.
