Authors: Tarko Laszlo , Pintilie Lucia , Negut Catalina , Oniscu Corneliu , Caproiu Miron Teodor
Published: March 2020

This paper presents results of three QSAR (Quantitative Structure Activity Relationship) studies realized with the PRECLAV computer program. The database we used contains initially 100 derivatives of 3-carboxy-4-quinolone. The dependent property is bactericidal activity against Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa. A specific criterion identifies the outlier molecules in the calibration set. Two molecules are identified as �possible outliers for lead hopping�. After the elimination of outliers, we obtained: N = 77 / 86 / 84, s = 0.2904 / 0.3583 / 0.2993, r2 = 0.8850 / 0.7943 / 0.8645, F = 91.1 / 37.6 / 82.9 and r2CV = 0.8415 / 0.7337 / 0.8415. The bactericidal activity against the three studied bacteria was favored by the presence of saturated C substituted (hetero)cycles, by the presence of certain groups (-F, unconjugated -NH/-NH2) and by a non-balanced molecular shape. The bactericidal activity was disfavored by the presence of certain chemical groups (-NO2, -C6H4, -CO-) and of the triazole cycle. The lipophilic/hydrophilic feature of quinolones has little impact upon bactericidal activity.

Use of Ecotoxicological Risk Evaluation Concept for Chemical Substances in Prediction of Irradiation Danger in a Surface Uranifer Tailing Dump
Authors: Bragea Mihaela , Perju Delia , Jinescu Gheorghita , Poiana Mariana
Published: March 2020

The concept of a comparative risk analysis presented here is based on the assumption that persistence, bioaccumulation and toxicity are a valid basis for a risk evaluation, if they are understood as generalized indicators and if they are completed by the two additional indicators release and uncertainty. Such a use of five indicators covers the whole pathway relevant for decisions, starting from information about the entry of the substance into the environment up to reflexive information about the quality of the evaluation. A revised comparative risk analysis of the radium 226 and uranium is presented. In this paper, the five risk indicators release T, spatiotemporal range R, bioaccumulation B, biological activity A and uncertainty I are used for the evaluation of a tailing dump from Ciudanovi�a, Cara� - Severin.

Authors: Stoica Ligia , Irimia Adriana , Oproiu Gabriela Carmen , Ordeanu Viorel
Published: March 2020

The optimization of arsenic separation by dissolved air flotation requires thoughtful consideration of the kinetics of the process. The overall flotation complexity, determined by several primary simultaneous and succesive micro-processes developed in space and time, chemical factors, hydrodynamic and mass transfer factors, is limiting the kinetic approach to estimate the overall order of the process and the overall rate constant, by analogy with chemical reaction kinetics. Kinetic modelling on different ore flotation models and interpretation of statistical fitting parameters were performed in order to establish the validity of the semi-empirical models for experimental data of the studied system.

Fractal Model of the Atom in the Hydrodynamic Approach of Scale Relativity Theory
Authors: Antici Adina , Paun Viorel-Puiu , Nica Petru , Agop Maricel
Published: March 2020

In this paper the fractal model of the atom, using the hydrodynamic approach of the scale relativity theory, is obtained. Thus, assuming that the electron motion around the nucleus takes place on fractal curves of fractal dimension DF (continuous but non-differentiable curves), it is shown that its dynamics, in the second order approximation of the equation of motion, is described in complex speed field by a generalized Navier-Stokes type equation with imaginary viscosity coefficient. Applying this model to study the atom, it resulted that the real part of the complex velocity field describes the electron averaged movement. The electron moves on stationary orbits according to a quantification condition and the imaginary part of the complex velocity describes the fractality through a fractal potential. In the DF=2 fractal dimension and for the D=h / 2m viscosity coefficient, the classical results of quantum mechanics for the hydrogen atom are obtained.

Published: March 2020

The electrochemical process of the solid titanium dioxide develops in the complex system: TiO2 (solid, sintered cathode) � CaCl2 (liquid, electrolyte) � C (anode, graphite). As a consequence of the chemical and electrochemical reactions which take place in this system, with determined conditions of temperature and potential, are finally formed solid metallic titanium (at the cathode) and oxygen (at the anode). The general reaction of the process is: TiO2(s) = Ti(s)+O2(g). A series of other reactions, implying the presence of other components (elements and compounds), as Ca, CaO, CaTiO3, C, CO, CO2, etc., are possible in certain conditions and stages of the process. In the paper are analyzed the main reactions which occur in the process, by their thermodynamic study. Through mathematical processing of thermodynamic data for the main reactions in the system, recently published in the literature, there was determined the temperature dependence of the Free Gibbs Energy, and based on it the values of the electrode potential were computed. In this manner was possible to prove that chemical reactions that could not spontaneously evolve, can develop in the electrochemical process by means of a corresponding voltage applied on the electrolysis cell.

Published: March 2020

As there is a broad range of constructive features and � more important � operating conditions regarding calciners that are used in clinkering plants, CFD simulations could be an effective tool in increasing their performance. A methodology that could be used to optimize their functioning is given here. In brief, CFD simulations are carried out both for computing the average gases velocity at their passage through the calciner and visualize exactly the flow patterns within the vessel. By properly adjusting dimensional and design features with the known outputs from the neighboring apparatus and with the required retention time of the particles in the calciner corresponding to a given decarbonation degree one could reach high running efficiency with low energy loses, without the need for demanding and expensive live trials.

Authors: Weber Viky , Popescu Adrian Radu , Oancea Ana Maria S.
Published: March 2020

The main objective of the present work was to determine the intraparticle interdiffusion coefficients in weak acid resins containing carboxylic acid groups, namely Purolite PPC 104 gel-like and C106 macroporous. The rate of H+/Na+ ion exchange process was measured on weak acid resins with gel and macroporous matrices using a potentiometric method under conditions favouring a particle diffusion controlled mechanism. The results obtained in experiments performed at different stirring speeds and size fractions support the mechanism. The H+/Na+ interdiffusion coefficients on the resins were obtained by modelling the data with quasi-homogeneous resin phase and bidisperse pore kinetic models, considering a parallel and two-stage interdiffusion in macro- and micropores, respectively. The macropore interdiffusion coefficients in the macroporous resin obtained with bidisperse pore kinetic model are higher than those calculated with quasi-homogeneous models and higher than the interdiffusion coefficients in the gel resin.

Gibbs Free Energy�Basicity Correlation in Binary Silica-Alkali Systems
Authors: Radu Dorel , Dumitrescu Ovidiu
Published: March 2020

In binary silica-alkali systems, the alkaline oxide reacts with SiO2 or with an alkali-silica compound in a chemical reaction characterized by the reaction constant Kp. At thermodynamic equilibrium Kp is calculated as a function of standard Gibbs free energy, DrGo298, and reaction temperature. The reactions between the various components of binary oxide systems M2O � SiO2 (M � alkaline ion) are acid-base type. These reactions take place between the different oxygen ion species having different basicities; consequently, the reactions equilibrium, evidently, depends on the difference of basicity. The present paper deals with the correlation between the standard free energy of formation, (DGo298), and the basicity percentage, pB, for binary compounds of the studied alkali-silica systems. The obtained relations show quantitative dependence between the standard reaction free energy, (- DrGo298), and basicity difference, DpB, for the same binary alkali-silica systems. It was observed that higher the saturation of SiO2 tetrahedron with metal ions leads to a decrease of the basicity difference between the reactants in the following order SiO2 disilicate � metasilicate � orthosilicate and confirms that the driving force of reactions is the acid-base interaction between the oxides and intermediate formed silicates.

A series of substances recommended as biological or chemical decontamination agents and new synthesized substances (e.g. Alkyl-phosphates) were tested. Among these we selected the microbiocide Alkyl-phosphate 2005, a complex mixture of aminosalts: mono- and bi- Alkyl-phosphates, which have in their molecular structures a variable percent of free acid functions were selected. It is a universal micro biocide with bactericide, fungicide, algaecide effects, with multiple uses, reduced toxicity and a minimum ecological impact. The products are liquids or solids, depending on their ester groups structures (R1, R2, R3 = ALKYL or/and ARIL) and amino components. The solubility of these products in water or in different common solvents is also a condition of their molecular structures. The substances are characterized by a high chemical stability to storing, solar radiation, and atmospheric oxygen etc. Also, the products are chemically stable in conditioning compositions and in direct contact to protected materials. The product is insoluble in water but is soluble in different organic solvents. After washing the objects or wetting the surfaces by spraying, the product makes a residual layer with disinfectant properties for a long period of time. The mixtures of compounds (I) and (II) are characterized by a strong microbiological activity developed, even at low levels of concentration (0.07% - 0.2 %), on a wide spectrum with bactericide, fungicide, algaecide effects etc., having at the same time a repellent and insecticide action. Laboratory tests proved the effectiveness of these products for positive-gram bacteria and also for negative-gram bacteria. These substances are characterized through a low toxicity for mammals and human subjects, feature that doesn�t impose specific measures in labor protection during preparation, conditioning, handling or use. Even more, when contacted with STL or toxins, these substances usually decompose into non-toxic compounds. By proper conditioning, products with multiple decontaminant effects can be obtained. The Alkyl-phosphate 2005 product can be used with very good results also as a decontaminant against bio-terrorism attacks.

The study presents the effect of Zn and Mn overdoses in relation with other trace metals in rat�s liver. All studied metals are involved in some enzymes activity, which are implicated in antioxidant defense system of the body. But, in some conditions � our case in overdoses � an imbalance can appear, and antioxidant character of a metal can become prooxidant. In this case, antagonistic or synergic behaviour in relation with other trace metals is obvious. The observed modifications are the increasing of zinc and manganese level in liver after solutions administration, and the amplification effect over the hepatic iron, with the possibility of oxidative stress appearance.
Arrest of Property in Bankruptcy Cases
Authors: Biryukov Oleksandr
Published: March 2020

This article focuses on the analysis of certain aspects of the application of security measures in liquidation procedure governed by Bankruptcy Law.

Arrest of property (according to Ukrainian legislation terminology — a seizure of property) as a temporary tool of enforcing future court decisions is a fairly popular legal tool to protect the parties’ property interests in money disputes. In modern court practice application of this legal remedy creates some difficulties, particularly, in bankruptcy cases. When administering these cases, the judges sometimes consider petitions regarding imposing arrests of property or freeing restrictions over the property imposed in civil, administrative and criminal cases.

In such situations, there is a need to answer a question whether the commercial court in a bankruptcy case has a power to free arrests or other restrictions on using the property imposed by other courts. Current legislation i.e. both procedural law and bankruptcy law does not contain clear rules on how the judges should aсt in such situations.

Different approaches to the application of bankruptcy proceedings regarding arrest of property influence the court practice in general. Some economic courts establish that the release of the debtor’s assets from bans and arrests during the bankruptcy proceeding is totally in accordance with the current law, other courts rule that commercial procedural code does not allow to free property from arrest imposed, for example, in civil cases as this arrest is done by civil procedural law.

Arrests attached in the criminal proceedings have different nature and purpose. It is known that in most cases in the criminal law property arrest serves as means to ensure possible future confiscation of property that may have been obtained in an illegal way. During such court proceedings a special review is conducted in order to discover whether property in acquired legally. Therefore, in order to cancel arrest of the property the procedure should be exercised in accordance with the rules of the criminal proceedings. However, while imposing new arrests of property in criminal proceedings it should be taken into account that the legal status of a person who was declared bankrupt has changed, i.e. he is deprived of the right to dispose the property which becomes a subject for sale at public tenders.

The main conclusion of this article is that existence of certain different approaches to application of security measures in different court proceedings can be explained by the fact that during the development of procedural laws the nature of insolvency relations and the peculiarities of the legal mechanisms used in bankruptcy cases were not fully taken into account.

REFLEXIONES EN TORNO A LA CALIDAD Y LA PERTINENCIA DE LA EDUCACIÓN COLOMBIANA DESDE LA PERSPECTIVA DE LA EVALUACIÓN DE LOS APRENDIZAJES
Authors: Correa Suárez Guillermo León
Published: March 2020

Este ensayo es una reflexión acerca de la educación como eje fundamental para el porvenir de cualquier nación en el planeta. Sin educación los pueblos no progresan, tal hecho se constata diariamente en la realidad mundial. La educación es la llave que abre todas las puertas. Se analiza además la realidad educativa colombiana en términos de calidad y pertinencia de la educación, la tendencia a la estandarización a partir de las pruebas de estado, que responden a requerimientos impuestos desde organizaciones internacionales con motivaciones estrictamente económicas. Por último se profundiza en el papel que los maestros tienen en la transformación coyuntural del modelo educativo en el actual momento de la historia del país.  “La escuela ha fracasado” es la conclusión a la que se puede llegar al ver el tipo de ciudadanos que se están formando en Colombia; la corrupción, el deplorable manejo del medio ambiente, la violencia presente; son entre otras tantas, las consecuencias de ello, por eso debemos despertar y promover ese cambio desde la gestión escolar, el diseño y la ejecución de los programas pertinentes a las necesidades del mundo de hoy. Pero es en el maestro donde hay que centrar los esfuerzos ya que este tiene estima social por su labor loable, pero no estatus social, la capacitación y el mejoramiento de las condiciones laborales de los docentes, la formación en liderazgo y en habilidades sociales para los promotores de la educación  son una exigencia en el mundo y específicamente en Colombia si queremos que se den los avances que deseamos en educación.
Power and Resistance : Variations on “what’s going on politically in and around organizations?”

general and organizational and management theory in particular. It is to be found at the heart of all social relationships, and forms a leitmotiv for social action (Russell, 1938; Foucault, 1977; Laclau & Mouffe, 1985; Clegg, 1989; Machiavelli, 1981). In other words, it is an integral part of social living involving groups or individuals within organizations. Although its role is a pivotal one, the “scientific” treatment to which this concept is subjected gives rise to a paradox in that substantial organizational research overtly dedicated to the topic are still few and far between. This is in spite of the numerous empirical projects which have been carried out and the excellent synoptic works which now exist. All things considered, one could assume either that power is merely subordinate to other organization-based social phenomena or that, by dint of its very significance, power merits only the courtesy of a “passing” glance, and constitutes so obvious a topic of discussion that we need barely tarry to pay it any particular attention.
De la salud pública a la Cobertura Universal de Salud: el caso argentino / From public health to Universal Health Coverage: the Argentinian case
Authors: Cejas Romanelli Pablo Sebastián
Published: March 2020

La salud pública es un concepto dinámico que obligó a los operadores sanitarios a pensar en estrategias de promoción y protección de la salud humana. Con el paso del tiempo, dicho concepto evolucionó hacia el de salud internacional, y este último, al de salud global en un contexto de globalización.

La Organización Mundial de la Salud (OMS) se perfiló como el ente destinado a instrumentar las políticas de salud global. En tal sentido la Cobertura Universal de Salud surgió como el resultado de la política de dicha organización que no estuvo exenta de presiones y controles de organismos no estatales.

La República Argentina incorporó al sistema de salud nacional, la Cobertura Universal de Salud que, tal como se verificó en la normativa internacional que le dio nacimiento, la prioridad está puesta en la salud financiera del sistema sanitario antes que en el derecho a la salud.

Public health is a dynamic concept that forced healthcare operators to think about strategies for the promotion and protection of human health. With the passage of time, this concept evolved towards international health, and the latter, to global health in a context of globalization.

The World Health Organization (WHO) emerged as the entity destined to implement global health policies. In this regard, the Universal Health Coverage emerged as the result of the policy of this organization that was not exempt from pressures and controls by non-state organizations.

The Argentine Republic incorporated into the national health system, the Universal Health Coverage that, as verified in the international regulations that gave birth to it, the priority is placed on the financial health of the health system rather than on the right to health.
El derecho a la salud y la publicidad infantil. Análisis en base a la normativa vigente en Argentina / Right to health and child advertising. Analysis based on current legislation in Argentina
Authors: Gerbaldo María Victoria , Merlo Vijarra Maga , Mozzoni Agustina
Published: March 2020

El presente artículo plantea la conexión existente entre el régimen protectorio del derecho a la salud, los derechos de los niños, niñas y adolescentes, y el régimen del Consumidor.

En Argentina, la protección a la salud dentro de las relaciones de consumo es una prioridad, así, pues, el resguardo de los intereses económicos del “consumidor”, como su salud tienen jerarquía constitucional. El carácter tuitivo se justifica en la asimetría que caracteriza a la “relación de consumo”; situación que se agrava cuando personas que ya son vulnerables forman parte de ella. Lo expresado cobra mayor relevancia al analizar la publicidad dirigida al público infantil, específicamente la de alimentos no saludables. Esto último, ha sido limitado en varios países y ha sido objeto de pronunciamientos judiciales en Latinoamérica.

Realizando la interpretación de todo el ordenamiento jurídico se pueden ofrecer razones para prohibir la publicidad de alimentos no saludables dirigida a un público infantil.

 

This article analyzes the connection between the regulations to the right to health, the right of children and adolescents and consumer`s regime. The protection to the health within the norms that regulate the consumption is a priority. In Argentina the protection of the economic interests of the "consumer", as well as, his/her health has a constitutional hierarchy. The tuitive character is justified by the asymmetry that is intrinsic to the "consumption relationship". This is even worse when people who are already vulnerable are involved in this relationship. This becomes more relevant when children`s advertising is analyzed, specifically unhealthy food advertising. This has been limited in several countries and has been subjected to judicial pronouncements in Latin America. By making an adequate interpretation of the entire legal system, good reasons can be offered to prohibit the advertising of unhealthy food addressed to a child audience.

Authors: De Cicco Andrés Oscar

La Corte Suprema de Justicia de la Nación revocó la sentencia dictada por el máximo tribunal de la provincia de Río Negro, que había desestimado una acción de amparo por improcedente, y que fuera oportunamente promovida por una abuela en representación de sus dos nietos a cargo, uno de ellos menor de edad y otro con discapacidad.

When Glöer & Hirschfelder in 2019 described the new species Bythinella magdalenae, they overlooked the description of Bythinella magdalenae Yıldırım, Kebapçı & Bahadır Koca, 2015. Thus B. magdalenae Glöer & Hirschfelder 2019 is a homonym. To give this species an available name we describe it with the replacement name Bythinella rethymnonensis n. sp., because it occurs in the regional unit of Rethymno.

Central Council of Ukraine: Introduction to Foreign Policy Activity
Authors: Verstiuk Vladyslav
Published: March 2020

The article describes the time when after the fall of autocracy in the Russian Empire, the power was taken by the Central Council of Ukraine emerged in Kyiv.
The fall of autocracy gave a chance for change, the newly formed Provisional Government declared its inclination to renewal and democratization processes. Ukrainians enthusiastically met the revolution. The Central Council of Ukraine emerged in Kyiv to head the national liberation movement. It based the political strategy on the slogan of gaining national-territorial autonomy of Ukraine in the Federal Democratic Republic of Russia.
The strength of the federalist-autonomous model was that in the First World War it made it possible to legitimately put the “Ukrainian question” to the Provisional Government and the Russian political elite without being accused of separatism.
Signing of the Brest Peace Treaty testified to the success of young non-professional Ukrainian diplomacy.
This was the first earnest act of the UPR on the international scene. However, given the circumstances Ukraine experienced, it had small effect. The difference could have been made only by a third-party military aid from countries of the Fourth Alliance, which later resulted in the occupation of Ukrainian lands. Unfortunately, it turned into the occupation of Ukrainian lands.
The weakest side of the Central Council was its Foreign policy. It was started with a considerable delay, it was a late reaction to the actions of the Bolsheviks. As a result, the Central Council failed to achieve recognition among the Entente countries, and a peace treaty with the Fourth Alliance in the long run, after the end of the World War, compromised Ukrainian statehood in the eyes of the victors.
The author emphasizes that wartime occupations acquire take the form of colonial exploitation and subordination regimes, which is clearly illustrated by the Central Powers’ presence in Ukraine in 1918.
It is also concluded that the Central Council, willing to rescue Ukraine from one disaster, brought it new challenges.
