Published: March 2020

The aim of this study is to bring personal contributions referring to the influence of aluminum ion (Al3+) on some biological systems. For this research the biological system was represented by an experimental design on domestic rabbits, working with three groups (one control group � C and two experimental groups � E1 and E2). The procedure was realized by aluminum solutions administration, with and without association of citrate to E1 and E2 groups, compared to control group. We followed the variation of some lipids in blood serum (total lipids, triglycerides, total cholesterol, HDL-cholesterol, LDL-cholesterol), the iron and total capacity for binding iron from blood serum, but also the modification of the concentration of trace and macroelements from liver of experimental animals. In our study are also presented chemical interactions specific for oxidative stress, process owed to the presence of aluminum ion (Al3+), which cause variations in lipidic metabolism.

Published: March 2020

Bilberries are known for their bioactive properties such as antioxidant activity. They contain a wide range of flavonoids and phenolic acids that show antioxidant activity. In the present work, the total phenolic and flavonoid contents, correlated with antioxidant activity of Vaccinium extracts were determined. The content of total phenolics in the extracts was determined spectrometrically according to the Folin-Ciocalteu procedure and calculated as gallic acid equivalents (GAE). The content of total flavonoids was measured also spectrophotometrically by using the aluminum chloride colorimetric assay. Effects of ethanol and methanol concentrations of the solutions on the contents of flavonoids and phenolic in extracts were investigated.
Ratio Spectra-Continuous Wavelet Transform and Ratio Spectra-Derivative Spectrophotometry for the Quantitative Analysis of Effervescent Tablets of Vitamin C and Aspirin
Authors: Dinc Erdal , Baleanu Dumitru
Published: March 2020

Simultaneous spectrophotometric analysis of tablets and binary mixtures containing vitamin C (VC) and aspirin (ASP) with overlapping spectra was performed by ratio spectra-continuous wavelet transform (RS-CWT) and ratio spectra-derivative spectrophotometry (RS-DS). In the application of RS-CWT and RS-DS to the simultaneous analysis of VC and ASP no separation step was considered. The basis of RS-CWT and RS-DS approaches is the transformation and the derivation of the ratio spectra of the related compounds and their samples. Calibration graphs in the linear concentration range 4-20 mg/mL for both compounds were obtained by measuring the CWT and first derivative amplitudes at 260.8 nm for VC and 234.6 nm for ASP in the BIOR-CWT spectra and at 256.0 nm for VC and 230.7 nm for ASP in the first derivative of ratio spectra, respectively. Both methods were tested by using the synthetic mixtures and standard addition technique, and were applied to the simultaneous determination of VC and ASP in commercial effervescent tablets and a good coincidence was reported for experimental results obtained by the proposed RS-CWT and RS-DS.

Authors: Segneanu Adina , Milea Marius , Simon Monika , Csunderlik Carol
Published: March 2020

The synthesis of mixed primary-, secondary-, and tertiary-alkyl phthalimidyl carbonates from N,N�-Diphtalimidylcarbonate (DPC) can be performed in a facile way, in one step reaction and with good yields. This new carbonate compound is usefull for peptide synthesis in preparation of active esters (activation step) and also in the protecting reactions by alkoxycarbonylation at nitrogen nucleophiles of amine- and aminoacid-types. It was proved that N,N�-diphtalimidylcarbonate (DPC) exhibited a similar reactivity to N,N�-disuccinimidylcarbonate, but the advantage of DPC seems to be that N-hydroxyphthalimide can be easily recovered quantitatively after the reaction.

Authors: Soica Codruta , Dehelean Cristina A. , Ordodi Valentin , Antal Diana , Vlaia Vicentiu
Published: March 2020

Birch bark contains important pentacyclic triterpens that determine an anticancer, anti-inflammatory and antiviral activity. The compounds can be extracted by simple procedures with organic solvents. The major problem of this type of triterpens is their low water solubility which can be increased by physical procedures like cyclodextrin complexation. The aim of present study was to analyse the products between birch bark extract and hydroxypropyl-g -cyclodextrin. Hydroxypropyl-g -cyclodextrin (HPGCD) was used as a host to improve its solubility in water, via inclusion complex formation. In order to obtain the inclusion complexes, 1:2 molar ratio and two preparation methods (physical mixing, kneading) were used. The inclusion complexes were analyzed by in vitro dissolution tests, thermal analysis and X-ray diffraction.

Authors: Cozmuta Leonard Mihaly , Varga Camelia , Marian Monica , Cozmuta Anca Mihaly , Hlanganani Tutu
Published: March 2020

Artificial neuronal networks are widely used in different fields such as finance, medicine, engineering, geology, chemistry, physics in order to predict, classify and control the development of different processes.
The paper presents experimental data on the adsorption process of copper from aqueous solutions and compares it with theoretical data obtained by mathematical modeling using artificial neural networks (ANN). The aim of the paper is to demonstrate that ANN ensure a high accuracy in the mathematical modeling of the process. We have collected experimental data by using synthetic solutions with different pH and cooper ions concentrations, which were retained on a PUROLITE S930 cationic resin. Both experimental and theoretical data obtained using ANN show the correlation between factors which influence the ionic exchange process (pH, temperature, initial copper concentration, activation energy).

Modelling Gas Processing Unit: An Inter-disciplinary Approach Based on Petri Nets
Authors: Mihalache Sanda Florentina
Published: March 2020

A modelling approach that will facilitate an in-depth understanding of the interactions of the different phenomena, human interactions and environmental factors constituting �real world� industrial processes is presented. An important industrial system such as Gas Processing Unit (GPU) have inter-related internal process activities coexisting with external events and requires a real time inter-disciplinary approach to model them. This modeling framework is based on identifying as modules, the part of processes that have interactions and can be considered active participants in overall behaviour. The selected initial set of modules are structured as Petri net models and made to interact iteratively to provide process states of the system. The modeling goal is accomplished by identifying the evolution of the process states as a means of effective representation of the �actual running�� of the industrial process. The paper discusses the function and the implementation of the modelling method as applicable to the industrial case of GPU.

Authors: Isopescu Raluca , Woinaroschy Alexandru , Draghiciu Loredana
Published: March 2020

The paper presents the analysis of the thermal efficiency of a dividing wall distillation column and the influence of the feed composition on the reduction of energy consumption compared to a classical scheme of multicomponent mixture separation. The study relays on rigorous simulations in HYSYSTM using thermodynamically equivalent schemes. A case study is presented for the separation of a hydrocarbon mixture: benzene, toluene, ethylbenzene, o-xylene separated in three products in a dividing wall column. The dividing wall column solution led to about 40 % energy saving. The efficiency of a dividing wall column increases when the middle component is in large amount in the feed.
The Influence of the Inorganic Species on Oxidative Degradation of 4-chlorophenol by Photo-Fenton Type Process
Authors: Orbeci Cristina , Untea Ion , Kopsiaftis Giorgios
Published: March 2020

An experimental study on 4-chlorophenol (4-CP) degradation in aqueous solutions by advanced oxidation process photo-Fenton type is presented. The efficiency of the oxidation process is determined by the very high oxidative potential of the OH. radicals generated by catalytic and photo-catalytic processes. The presence of the inorganic species inside the reaction medium influences the rate of the oxidation process as function of their nature and concentration. The inorganic anionic species reduce drastically the 4-CP oxidation efficiency by Fe2+/3+ complexing processes, HO. radicals scavenging effect or iron precipitate forming. The decrease of the 4-CP oxidation degree is correlated with the nature of the anions as following: Cl- ] PO43- ] SO42- ]] NO3-. The presence of the insoluble inorganic species (bentonite) modifies the oxidation efficiency by additional 4-CP and UV sorption processes, especially at high solution turbidity values.

Authors: Atkinson Irina , Teoreanu Ion , Zaharescu Maria
Published: March 2020

This study aims to investigate the structure and properties of raw glazes with zirconium and boron addition for sanitary porcelain. To obtain the glazes under investigation the following raw materials were used: potassium feldspar, kaolin, wollastonite, quartz, colemanite, ZnO and ZrO2. The glazes were prepared by traditional ceramic method and the resulted suspension was applied on the green ceramic substrate and thermally treated in an electrical furnace with a treatment time of 1 hour at the maximum temperature of 12500C. The microstructure of the glazes and the glaze-ceramic substrate interfaces were evaluated by SEM and EDAX microanalysis, which showed the presence of zircon micro crystals. X-Ray diffraction revealed that the mineralogical composition of the glazes consisted of quartz, zircon, feldspar and colemanite phases. The correlation between the composition and properties of the glazes was established by hot stage microscopy and dilatometry (melt viscosity, contact angle and thermal expansion coefficient). The colour characteristics were estimated in the HunterLab system (L* C* h*, remission spectra).
Characterization of Saccharomyces cerevisiae Mutants Resistant to High Concentrations of Co2+: A Primary Step to Bioremediation by Removal and Recovery of Co2+ from Waste Waters
Authors: Farcasanu Ileana Cornelia , Oprea Eliza , Paraschivescu Codruta , Ruta Lavinia , Avramescu Sorin
Published: March 2020

Engineering cell lines that hyperaccumulate heavy metals can be an invaluable tool in removing such ions from aqueous environments. In this study we obtained Saccharomyces cerevisiae mutants that were tolerant to high concentrations of Co2+. Chemically mutagenized yeast cells were plated on media containing lethal doses of Co2+. Five resistant colonies were isolated and characterized in terms of Co2+ tolerance and cation accumulation. Four mutants gained the Co2+-tolerance due to low level of accumulation, and only one mutant had the capacity to hyperaccumulate Co2+. Monitoring the intracellular distribution of Co2+ in the hyperaccumulating mutant revealed that the cation was mainly compartmentalized within the vacuoles. Utilizing hyperaccumulating mutants may facilitate the rational design of strategies for bioremediation of heavy metal waste waters.

Fantastic Beings and Where to Make Them ‒ Boats as Object-Beings in Bronze Age Rock Art
Authors: Fahlander Fredrik
Published: March 2020

The boat motif in Bronze Age rock art is generally assumed to represent real or symbolic boats in some form. In this paper, however, it is argued that Bronze Age rock art motifs are independent material articulations, made to do something rather than to represent. From such a perspective, the hybrid character of the boat motif as part animal, part object is conceived as a special type of entity, an object-being that has no original elsewhere. The change of perspective, from representation to articulation, and from object to being, allows for a more coherent view of Bronze Age rock art as primarily enacted imagery integrated with rock and metal as vitalist devices, aimed to affect the world.
La gestación por sustitución en el derecho y la jurisprudencia argentina / The gestational surrogacy in argentine law and jurisprudence
Authors: Asnal Silvana Del Carmen
Published: March 2020

El tema de la gestación por sustitución, subrogación de vientre o maternidad subrogada resulta, para algunos, una de las cuestiones más nuevas y actuales que presenta el Derecho de las Familias. Sin embargo, luego del análisis que se realizará en este trabajo, se podría concluir que ello no es tan así.En el presente se plantea, como cuestión principal, si la falta de regulación por parte del Código Civil y Comercial y/o leyes complementarias ha sido obstáculo para que la figura de la gestación por sustitución sea utilizada.La respuesta a esa cuestión es negativa. Como se demostrará a lo largo del trabajo, la falta de legislación no impidió que numerosos casos hayan sido sometidos a decisiones de la justicia nacional, antes y después de la vigencia del nuevo Código Civil y Comercial (en adelante CCC), que hoy innova en la regulación de las Técnicas de Reproducción Humana Asistida (en adelante TRHA), pero no ha incorporado regulación alguna con respecto a la gestación por sustitución. El vacío legal fue cubierto, antes y ahora por la doctrina y, sobre todo, por la jurisprudencia.

 

The Gestational surrogacy, for some, is a new and current theme in de Family Rights. However, after analyze made this dissertation, we can infer that this inference is wrong.The main question is if lack of regulation in the new Civil and Comercial Code, or in complementary laws, has been an obstacle to use the Gestational surrogacy.The answer in negative. Because lack of regulation did nonstop to many people, who resort to national justice, before and after the new Code.

This Code innovates in assisted humans reproduction techniques. However, there are no regulations about the Gestational surrogacy. The void was covered by jurisprudence and doctrinarians.

Derecho, salud y políticas públicas: el nuevo paradigma en salud mental y su impacto en las políticas de Estado / Health law and public policies: the new paradigm in mental health and its impact in State policies
Authors: Halac Gordillo Lucila
Published: March 2020

El presente ensayo propone delinear el nuevo paradigma en salud mental, partiendo de la sanción de leyes especiales, Código Civil de la Nación, y Tratados internacionales a los que Argentina adhiere, en consonancia con los avances de la ciencia médica, con una visión práctica, procurando analizar su recepción en las políticas de Estado, recorriendo los pilares normativos de la nueva concepción, seleccionando doctrina relacionada.

En esta tarea, hemos descubierto gran interés de la prensa en numerosos artículos periodísticos que dan cuenta que el tema esta instalado, que una sociedad mas inclusiva y permeable lo ha receptado, para así llegar a las políticas de Estado que incluyen en sus agendas la necesidad de cambios estructurales, los que se encuentran aún en un difícil camino de realización.

 

This essay proposes to delineate the new paradigm in mental health, starting from the sanction of special laws, Civil Code of the Nation, and international treaties to which Argentina adheres, in consonance with the advances of medical science, with a practical vision, trying to analyze its reception in State policies, going through the normative pillars of the new conception, selecting related doctrine.

In this task, we have discovered great interest of the press in numerous journalistic articles that show that the topic is installed, that a more inclusive and permeable society has received it, in order to reach the State policies that include in their agendas the need for structural changes those that are still in a difficult path of realization.

El presente artículo analizará el fallo dictado por la Corte Suprema de Justicia de la Nación, a través del cual, hacen lugar al recurso extraordinario y deja sin efecto la sentencia impugnada por la demandada en la causa “C.T., N c/OSDE s/amparo de Salud”.  El órgano supremo de Justicia de la Nación consideró que la alzada carecía de fundamentos que dieran sustento a su decisión; así como también existía una clara omisión en la valoración de las pruebas aportadas por la parte demandada, lo que la colocaba en una situación desventajosa. Entiende la Corte que se está frente a otra de las tantas sentencias arbitrarias. ¿Incide entonces que se trate de derechos fundamentales, como es el derecho a la salud? ¿Pierden objetividad los magistrados cuando se encuentran involucrados esta clase de derechos? Se intentará dilucidar a continuación.

 

This article will analyze the sentence handed down by the Supreme Court of Justice of the Nation, through which, it leaves the sentence contested by the defendant in the case “CT, N c / OSDE s / amparo de Salud” without effect. The Supreme Court of Justice of the Nation considered that the elevation lacked grounds to support its decision; as well as there was a clear omission in the assessment of the evidence provided by the defendant, which placed it in a disadvantageous situation. The Court understands that it is facing another of the many arbitrary sentences. Does it imply that these are fundamental rights, such as the right to health? ¿Do magistrates lose objectivity when this kind of rights is involved? Attempts will be made to clarify below.

Published: March 2020

The aim of work was to investigate the diversification, structure, physiognomy and floristic richness of riverside terophytes from Bidentetea tripartitae class in selected coastal river valleys. The investigates area encompassed the lower and middle section of the river valleys of Rega, Parsęta, Wieprza, Słupia, Łupawa  in the Western Pomerania (Poland). 68 phytosociological records were made according to the system of Braun-Blanquet. A database was created with the help of the software Turboveg for Windows.The hierarchy classification with the MVSP package was used in order to arrange and group the collected phytosociological data and to single out the types of plant communities. In order to evaluate similarity of samples with respect to species composition the Bray Curtis was calculated and the Unweighted Pair Group Method with Arithmetic Mean (UPGMA) was applied. Three plant communities belonging to one alliance Bidention tripartitae were identified: Bidenti-Polygonetum hydropiperis (Miljan 1933) Lohmeyer in R.Tx. 1950 nom invers., Bidentetum cernui Kobendza 1948, community with Polygonum minus, and one plant community belonging to the alliance Chenopodion glauci: Chenopodietum rubri Timar 1947.Given the natural origin of most of the patches, their structure, and the relatively small share of synanthropic species, including alien species, it should be emphasized that they constitute a spontaneous stage of succession of riparian vegetation. The presence of therophyte communities in the valleys of the coastal rivers, as well as their structure and physiognomy, testify to the preservation of their natural character.

Published: March 2020

Papilio demoleus Linnaeus, 1758 (Lepidoptera: Papilionidae) is a widespread pest of citrus plants originating from the Oriental Region. Here, we report on the discovery of its non-native population recently established on Mahé, Seychelles. Papilio demoleus was probably accidentally introduced to Mahé a few years ago (first records in November 2016). Morphologically, the Seychelles population is identified as the subspecies Papilio demoleus malayanus Wallace, 1865 from Southeast Asia. It was one of the most abundant butterfly species at the southeastern edge of Mahé in January 2020. Our finding highlights that generalist butterfly species associated with agricultural plants are rapidly spreading throughout remote oceanic islands such as the Inner Seychelles.

One of the efforts to prevent maternal death is through antenatal class activities which are group learning facilities for pregnant women to improve maternal knowledge and skills regarding pregnancy, childbirth, postpartum care and newborns. In Indonesia the antenatal class is still weak in its implementation although it is known to be very likely to reduce maternal mortality. This study aims to determine the factors that influence the class utilization of pregnant women in the work area of Puskesmas Lima Puluh Pekanbaru in 2018. This type of observational analytic quantitative research with cross sectional designe. The study population consisted of 315 third trimester pregnant women with a sample of 104 mothers. Data analysis was carried out in univariate, bivariate and multivariate. The results of the multivariate analysis showed that the variables that were significantly related to the utilization of the antenatal class were knowledge (POR: 4,248; CI 95%: 1,444-12,501), husband's support (POR: 3,707; 95% CI: 1,252-10,975), attitude (POR: 3,479; CI 95%: 1,210-9,997) and support from health workers (POR: 5,367; 95% CI: 1,758- 16,382).
