Authors: Ustundag Ozgur , Dinc Erdal , Baleanu Dumitru
Published: March 2020

The simultaneous determination of pyridoxine hydrochloride (B6) and isoniazide (INH) in tablets was performed by using the Mexican hat wavelet function (MEXH). The absorption spectra of B6, INH and their samples were recorded in the spectral range of 200-330 nm. Linear regression functions for B6 and INH in the linear concentration range of 5-45 mg/mL were obtained by measuring the transformed signals at 253.5 nm corresponding to the zero-crossing point for INH and at 270.6 nm corresponding to the zero-points for B6, respectively. The validation of MEXH method was performed by using the synthetic mixtures. The percent mean recoveries and their relative standard deviations were found as 98.7% and 2.06 for B6 and 98.9 % and 1.89 for INH in the synthetic mixture analysis. The MEXH method was applied to the real samples and a good sensitivity and selectivity was reported. The MEXH method was sucessfully compared with classical derivative method.

Authors: Pektas Gozde , Dinc Erdal , Baleanu Dumitru
Published: March 2020

Principal component regression (PCR) and partial least squares (PLS) chemometric methods were applied to the simultaneous quantitative analysis of levamisole (LVM) and triclabendazole (TCB) in tablets without using a preliminary separation, even in presence of the overlapping spectra of the above compounds. For both PCR and PLS, a concentration set containing 25 different mixtures of LVM and TCB in the linear concentration range was symmetrically prepared and then the absorbance values of the concentration set were measured at the wavelength set with Dl=0.1 nm in the spectral region of 225-322.3 nm. PCR and PLS calibrations were obtained by applying the PCR and PLS algorithms to the concentration set data (y-block) and their corresponding absorbance data (x-block). The validity of PCR and PLS chemometric methods was performed by using the independent synthetic mixtures and the standard addition technique. Then, these analytical methods were applied to the commercial tablets and a good agreement was obtained between experimental results provided by the application of the PCR and PLS to the synthetic and real samples.

Published: March 2020

The catalytic activity of mixed alumina-supported copper-manganese oxides during complete oxidation of CO, ethylacetate, toluene and benzene is investigated. The samples were prepared by impregnation of g-Al2O3 with aqueous solutions of copper and manganese formates at room temperature and subsequent calcination at 670 K .All samples have been obtained using a fixed ratio between the two components in the impregnating solutions. The use of formates as precursors permits formation of mixed formates and their decomposition without preliminary melting thus resulting in the formations of oxide phases of high dispersity. The content of supported active metals was determined by chemical analysis. The specific surface area of the samples was measured using BET method and the magnetic susceptibility depending on temperature was investigated by the Faraday method at temperatures up to 620 K. The catalytic activity of the catalysts was measured in flow reactor.
Helical Diastereomerism in Self-organization of Molecular Strands
Authors: Barboiu Mihail , Lehn Jean-Marie
Published: March 2020

The polyheterocyclic molecule 2 reported in this paper is a helically-wrapped molecular strand presenting two helical substrands of same helicity separated in space thus forming P-P and M-M helical enantiomers. It represents the case of a molecule presenting two chiral centers of helical type. The dimerization process of the compound described in this paper appears to give rise to heterodimeric and homodimeric species. At high and room temperature the formation of dimeric species is accompanied by folding-unfolding interconversion of single molecular strands. Sliding of the monomers along one another without dissociation at low temperature allows each of two helical partners to associate in dimers stabilized by pronounced p�p stacking interactions between the internal heterocycles of the strands.

Authors: Blondeau Pascal , Legrand Yves-Marie , Lee Arie Van Der , Nasr Gihane , Barboiu Mihail
Published: March 2020

New crystalline coordination-polymers are obtained under conditions in which distinct metal ion coordination, hydrogen-bonding and p-p stacking subprograms are involved in independent binding events of ureidopyridyl ligands 1 and 2 by silver hexafluorophosphate or silver triflate. The geometrical information contained in the structure of the ligands 1 and 2 is fully exploited by the silver ion coordination and urea-self assembly or H-bond anion coordination templating features in an independent way. The resulted linear or angular sequences may serve to use the information stored in molecular components that could be read out by synergistic and sequential non-covalent subprograms. It results in linear or tubular supramolecular coordination polymers constructed in a bottom-up strategy.

Authors: Jipa Silviu , Kappel Wilhelm , Zaharescu Traian , Gorghiu1 Laura Monica , Dumitrescu Crinela
Published: March 2020

Most of the insulating solids have in their structure point defects, naturally occurring or artificially created, which induce electronic states in the forbidden band. These defects are strongly related with the thermoluminescence (TL) phenomenon. There are several models described in the literature which explain the basic principles of the TL process using charge carrier traps induced by impurities named dopants. This paper presents an example of analyzing the thermolumoinescence glow curves obtained for potassium tetraborate undoped and doped with Ag and Cu, respectively. On the base of these curves the kinetic parameters were calculated using some of the methods described in the literature. In addition, a comparison of the results obtained by applying these methods for K2B4O7 doped with Ag and Cu (1.2 and 1.5 mole %) samples is presented.

Authors: Nedeff Valentin , Mosnegutu Emilian , Panainte Mirela , Savin Carment , Macarescu Bogdan
Published: March 2020

The process of aerodynamic sorting of a solid particles mixture is influenced by the aerodynamic characteristics of the particles (shape, dimensions, the surface state and the density of the particle), which determine the behaviour of particles in the air flows. In this study it was analyzed the influence of the surface state of solid particles on the separation degree of a binary mixture, made from particles with smooth surface and particles with rough surface, submitted to the aerodynamic sorting. The correlation between the surface state of solid particles and their behavior in air flow is emphasized by the weight mass of the particles deposited in the collection boxes. It was observed that the particles with the smooth surface have higher floating velocities than the particles with the rough surface for closed dimensions, shapes and densities. The sorting process is influenced by the surface condition of the particle.

Compressor Issues for Hydrogen Production and Transmission Through a Long Distance Pipeline Network
Authors: Starr Fred , Cormos Calin-Cristian , Tzimas Evangelos , Peteves Stathis
Published: March 2020

A hydrogen energy system will require the production of hydrogen from coal-based gasification plants and its transmission through long distance pipelines at 70 � 100 bar. To overcome some problems of current gasifiers, which are limited in pressure capability, two options are explored, in-plant compression of the syngas and compression of the hydrogen at the plant exit. It is shown that whereas in-plant compression using centrifugal machines is practical, this is not a solution when compressing hydrogen at the plant exit. This is because of the low molecular weight of the hydrogen. It is also shown that if centrifugal compressors are to be used in a pipeline system, pressure drops will need to be restricted as even an advanced two-stage centrifugal compressor will be limited to a pressure ratio of 1.2. High strength steels are suitable for the in-plant compressor, but aluminium alloy will be required for a hydrogen pipeline compressor.
Materials for Anticorrosive Protection of Cellular Bodies of Rotatory Air Preheaters from Energentic Installations. Modification and Rheological Characterization of Some Epoxy Resins
Authors: Bantas Adriana , Cioroianu Lelian , Cioroianu Gabriela , Leca Minodora , Pica Alexandra , Marcovsci Claudiu
Published: March 2020

Celualar bodies from the cold region of the heat exchange surface of rotatory air preheaters from energetic installations are strongly affected by sulphuric corrosion and, can be protected using heat conducting and thermally resistant coatings. Epoxy resins, mofied firstly with tall and soy fatty acids to increase their elasticity and then reacted with acrylic acid and styrene to increase chemical, heat and corrosion resistance, adherence and elasticity, correspond to the qualities required for the film-forming material. The thermal conductivity of coating can be increased by introducing finely dispersed metal powders. Rheological measurement emphasizes that the resins esterified with both kinds of fatty acids have relatively low viscosities, ranging between 3500 and 8600 mPa.s, and ideal plastic fluid behaviour; the higher the epoxy equivalent of the resin the lower the viscosity of the esters. Treatment of resins (previoisly esterifies with tall fatty acids) with the two monomers increases the viscosity and modifies the rheological behaviour, transforming it into a pseudoplastic one. The increase of viscosity is huge for the resin having lower epoxy equivalent and its behaviour becomes thixotropic. Given the high specific weight of metal powders , it is expected that this last modified resin gives the most stable film-forming disperse systems with metal powders.

Authors: Branzoi Viorel , Pruna Alina , Branzoi Florina
Published: March 2020

The inhibition of zinc corrosion in 3.5% NaCl solution by some organic compounds (sodium dodecylsulphate (SDS), sodium dodecylbenzosulphonate (SDBS) and sodium 1,4-bis(2-etylhexyl) sulphosuccinate (AOT)) was investigated. The inhibition efficiencies were determined by polarization measurements of the zinc electrode in the solution. Electrochemical impedance spectroscopy (EIS) was also used for electrochemical studies of zinc electrode in this medium. The results showed that the used surfactants inhibit the cathodic reaction of hydrogen evolution and at low anodic overvoltage the corrosion process is under activation control, while at high anodic overvoltage the process is under diffusion control.
Experimental Studies Concerning the Semipermeable Membrane Separation Efficiency for 134Cs, 137Cs, 57Co, 58Co, 60Co, 54Mn in Liquid Radioactive Waste I. Treatment of secondary waste from POD decontamination procedure
Authors: Dulama Mirela , Deneanu Nicoleta , Dulama Cristian , Pavelescu Margarit
Published: March 2020

The paper presents the experimental tests concerning the treatment by membrane techniques of radioactive aqueous waste. Solutions, which have been treated by using the bench-scale installation, were radioactive simulated secondary wastes from the decontamination process with modified POD. Generally, an increasing of the retention is observed for most of the contaminants in the reverse osmosis experiments with pre-treatment steps. The main reason for taking a chemical treatment approach was to selectively remove soluble contaminants from the waste. In the optimization part of the precipitation step, several precipitation processes were compared. Based on this comparison, mixed [Fe(CN)6]4-/Al3+/Fe2+ was selected as a precipitation process applicable for precipitation of radionuclides and flocculation of suspended solid. Increased efficiencies for cesium radionuclides removal were obtained in natural zeolite adsorption pre-treatment stages and this was due to the fact that volcanic tuff used has a special affinity for this element. Usually, the addition of powdered active charcoal serves as an advanced purifying method used to remove organic compounds and residual radionuclides; thus by analyzing the experimental data (for POD wastes) one can observe a decreasing of about 50% for cobalt isotopes subsequently to the active charcoal adsorption.. The semipermeable membranes were used, which were prepared by the researchers from the Research Center for Macromolecular Materials and Membranes, Bucharest. The process efficiency was monitored by gamma spectrometry.

Published: March 2020

Vapour � liquid equilibrium, thermodynamic and volumetric properties were predicted for three pure hydrofluorocarbons: difluoromethane (R32), pentafluoroethane (R125) and 1,1,1,2 � tetrafluoroethane (R134a) as well as for binary and ternary mixtures of these refrigerants. Three cubic equations of state GEOS3C, SRK (Soave � Redlich � Kwong) and PR (Peng � Robinson) were used. A wide comparison with literature experimental data was made. For the refrigerant mixtures, classical van der Waals mixing rules without interaction parameters were used. The GEOS3C equation, with three parameters estimated by matching several points on the saturation curve (vapor pressure and corresponding liquid volumes), compares favorably to other equations in literature, being simple enough for applications.

Published: March 2020

The aim of this paper was the isolation and purification of medical interest polysaccharides from the European mistletoe (Viscum album L.) and their chemical and biological characterization in view of the usefulness for the regeneration of dermal tissue wounds. Four fractions (A1-A4) were obtained by ethanol precipitation of the polysaccharide aqueous total extract (PZT). The fraction A2 was the richest in hexoses (42.12 %) and was purified by ion-exchange chromatography, resulting six fractions (B1-B6). The chemical composition of the purified fractions showed that B3 had the highest content in hexoses (30.06 %) and uronic acids (23.74 %). The gelatin-zymography analysis of the proteinases secreted by the dermal fibroblasts in the presence of A2 and B3 samples has demonstrated that, at a concentration of 100 �g/ml, they didn�t affect the cellular metabolism. The spectrophotometric method used to study the influence of purified polysaccharides on cell viabillity showed that the tested fractions were not toxic. In conclusion, the selected polysaccharide fractions, A2 and B3, can be used as active compounds in the composition of bioproducts for the regeneration of injured dermal tissue.

De-contaminating the aDNA – archaeology dialogue on mobility and migration: discussing the culture-historical legacy
Authors: Furholt Martin
Published: March 2020

While the newly available ancient DNA data have shaken a lot of archaeological debates, they have, despite their enormous potential, not yet had any meaningful impact on the way we view prehistory. Instead of using this new data-source to explore new questions, or at least to re-assess the old ones, aDNA results have been tacked onto some of the most outdated narratives in European prehistory, stemming from the early twentieth century. The simplified Steppe migration narrative builds upon long-outdated culture-historical concepts, sloppy classification work, and a reliance on a monothetic culture concept which was convincingly deconstructed 50 years ago by David Clarke. In this paper, a polythetic approach to the material of the third millennium BC presents a different picture of the period. Additionally relying on a practice-based approach to how new transregional objects and practices are integrated into local contexts, it is argued that these two adjustments to our approach to the archaeological material can significantly improve the aDNA - archaeology dialogue, and better integrate the different datasets.
Casting in the Longhouse: the Organization of Metalworking at Late Bronze Age Settlements in South-eastern Sweden
Authors: Sörman Anna
Published: March 2020

Traces of bronze casting – fragmented moulds and crucibles - frequently occur at Late Bronze Age settlements. These traces are often assumed to represent utilitarian domestic production, in contrast to more specialised workshop production at ritual or elite locations. Moreover, settlements have often been reduced to overall production units, while actual arrangements of bronze casting within sites has remained unexplored. The aim of this paper is to provide new insight into the organization of metalworking from an empirical and ‘bottom up’ perspective by examining the spatial and social contexts of bronze casting. The analysis draws on ten excavated sites in south-eastern Sweden and addresses three spatial levels: site, setting and framing. The study shows that domestic arenas often hosted varied and complex metalworking staged at various indoor and outdoor hearths located in the core areas of settlements. Rather than being conceptualized as levels, the organization of Late Bronze Age metalworking was a multifaceted, communicative and user-oriented practice. These insights have consequences for excavation methods as well as for the interpretation of the role of metalworking in society

Con questo lavoro si vuole riflettere sulla semantica societaria – incentrata su termini quali ‘volontà’, ‘libertà’ e soprattutto ‘diritti’ – che descrive l’individualità moderna quale personalità soggettiva dotata della possibilità di distinguersi e di esercitare pretese. L’ambito di riflessione scelto è quello della salute, a partire dalla convinzione che esso rappresenti oggigiorno un contesto privilegiato per osservare la relazione tra individuo e società, tentando di capire quali spazi di azione personale e autonomia abbiano i singoli rispetto alle forze sociali che li condizionano. Alla riflessione di stampo teorico – attraverso la teoria dei sistemi sociali di Niklas Luhmann – sulle rivendicazioni del diritto alla salute, si aggiunge l’analisi della recente legge italiana sul “fine vita”, che consente l’adozione delle “disposizioni di trattamento” (DAT). L’ipotesi è che ciò rappresenti un esempio di riuscito equilibrio fra rivendicazioni dei singoli ed esercizio responsabile deidiritti, a vantaggio dell’integrazione societaria.

 

This work is about semantics of society – focused on terms such as ‘will’, ‘freedom’ and above all ‘rights’ – describing the modern individuality as a subjective personality endowed with the ability to be different and to exercise claims. We focus on health, starting from the idea that nowadays it is a perfect context to observe the relationship between individual and society, trying to understand which spaces for personal action and autonomy the individuals have, free from social influences. Beside the theoretical reflection – starting from the perspective of social systems theory by Niklas Luhmann – about claims in the area of the right to health, there is the analysis of the recent Italian law on “end of life”, which allows the adoption of “treatment provisions” (DAT). The hypothesis is that this represents an example of a successful balance between individual claims and responsible exercise of rights, to the advantage of integration of society.

Relaciones intergubernamentales y gestión pública de salud: Argentina y el caso de la Provincia de Córdoba / Intergovernmental relations and health public management: Argentina and the case of Córdoba
Authors: Bernal Marcelo , Bizarro Valeria
Published: March 2020

Las relaciones intergubernamentales resultan esenciales a la hora de examinar y definir los mecanismos de cooperación y de articulación entre los diferentes niveles de gobierno de un Estado federal, como es el caso argentino. En nuestro país podemos identificar dos fuertes movimientos descentralizadores de los aparatos de educación y de salud, el primero en los 70, y el segundo en los 90 del siglo pasado. Dicha descentralización se caracterizó por una escasa planificación, lo que implicó grandes complicaciones para las provincias que debieron gestionar y administrar miles de hospitales y escuelas sin una adecuada dotación de recursos, como así tampoco se tuvieron en cuenta mecanismos y agencias encargadas de coordinar esta trascendental reforma estatal. El principal objetivo de este trabajo es describir y analizar las relaciones intergubernamentales (RIGS) existentes en materia de políticas de salud en el eje Nación - provincias, sus principales características y las debilidades identificadas, con un anclaje específico en el caso de la Provincia de Córdoba. Para ello, se analizarán normas, instituciones y mecanismos de coordinación existentes en políticas de salud entre los gobiernos nacional y provinciales, con un especial acento en el caso de la Provincia de Córdoba.

 

Intergovernmental relations are essential when analyzing and defining the mechanisms of cooperation and articulation between the different levels of government of a federal State, such as the Argentine case. In our country there were two strong decentralizing movements of education and health apparatuses, the first in the 70s, and the second in the 90s of the last century. The main characteristic of this decentralization was a poor planning, which resulted in complications for the provinces that received thousands of hospitals and schools without adequate resources, as well as mechanisms and agencies in charge of coordinating this transcendental state reform. This paper specifically analyzes norms, institutions and mechanisms of coordination existing in health policies between the national and provincial governments, with a special accent in the case of the Province of Córdoba.

In the last decade the cypress jewel beetle Ovalisia festiva (Linnaeus, 1767) has become a real threat in many European countries. Although it was reported from Bulgaria long ago, there is no data on its current status. The aim of this study is to present new data on cypress jewel beetle’s distribution, damage and natural enemies in the country. The research was conducted in the period 2016-2019, with 106 localities on the territory of Bulgaria examined. As a result of the current study 16 localities new for this species were found. Our rearings identified adults of the parasitoid Metacolus unifasciatus Forster, 1856 (Hymenoptera, Pteromalidae) and the parasitizing mites belonging to genus Pyemotes. Amerling, 1861 (Acarina: Pyemotidae). The parasitoid-host association of M. unifasciatus with O. festiva is considered here a new biological relationship, not previously recorded for these species. Currently the cypress jewel beetle O. festiva is widely distributed in Bulgaria and can be regarded as an important pest in landscaping.
