Authors: Ozdemir Sahika , TONG Hakan
Published: March 2020

With the widespread use of computers, rule-based design methods that can work in harmony with computer logic and can be easily adapted to the computer environment have come to the forefront in the design world. To be able to analyze the logic of a design made with the shape grammar method which is one of the rule based design methods; it is even possible to modify and transform the design, which has been placed on the rule base by removing shape rules, or to create new designs with the same design logic. In this study, some stores that will be exemplary for the store design are examined, analyzed and the system is designed to produce new plan schemes. In this study, it is aimed to produce a program that offers abstract plan alternatives to the designer during the early design process. In store design, clothing stores are emphasized especially due to its intensive use. Within the scope of the study, it is focused on developing a program that produces plan alternatives by using computational power of computer. In this way, it was possible to work on many plan alternatives in a short time during the design process and it became easy to examine large areas. With these alternatives, it is aimed to provide rapid and advance detection of possible problems that may arise. At this point, it is aimed to see a large number of plan alternatives by applying a few rules and to make the appropriate selection among these alternatives.

Authors: Ozdemir Yavuz , Nalbant Kemal Gokhan
Published: March 2020

Personnel selection is an important business process for companies. Training, experience information and personal characteristics are important qualities for employee to be recruited. The most accurate result of the personnel selection is obtained from the qualified personnel by determining the personnel who is most suitable for the job requirements. The basic idea of personnel selection is to choose the best candidate for a job. Personnel selection is crucial in human resources management. A solution to the Multi Criteria Decision Making (MCDM) problem is Personnel selection. The main goal of this paper is to find the best personnel using the integrated Consistent Fuzzy Preference Relations (CFPR) and Fuzzy Analytic Hierarchy Process (FAHP) methodology. CFPR is used to obtain the importance weight of personnel selection criteria (22 sub-criteria are categorized under 5 main criteria). Then, the importance weights of personnel selection criteria are integrated with a FAHP model to prioritize the personnel alternatives. For a case study in Turkey, the ranking of the alternatives (17) is calculated using the integrated CFPR-FAHP model, and the best personnel is selected for promotion. This methodology makes it easier for managers/human resources department to decide on recruitment and personnel promotion. The proposed methodology provides the consistent results owing to the integrated methods. The main contribution in this study is the reduction of judgments for a preference matrix using the proposed methodology. To the authors’ knowledge, this study will be the first to integrate CFPR and FAHP methods for personnel selection.

Published: March 2020

O presente artigo é fruto de uma pesquisa realizada nos anos de 2011, 2012 e 2013, que objetivou analisar discursos de dirigentes, alunos e/ou ex-alunos de um curso de montanhismo de um clube da cidade do Rio de Janeiro (Centro Excursionista Rio de Janeiro - CERJ), a fim de verificar como estes praticantes significam essa atividade e sua relação com o meio ambiente por meio dela. Esta análise permitiu identificar conflitos dentro deste campo esportivo e tensionamentos entre os elementos que buscam legitimar um monopólio de definição da atividade em questão. Dessa forma, a investigação dos significados imputados ao montanhismo, ainda que por um grupo específico, permite repensar como a busca por uma imposição de sua maneira de praticar influencia sua própria realização, a relação entre homem e meio ambiente e o sentido do esporte.

Published: March 2020

É raro encontrar estudos que investigam materiais pedagógicos de divulgação do final do século XIX e início do XX, como é o caso da Cartilha de Higiene: Alfabeto da Saúde. Nesta pesquisa objetivamos refletir sobre a maneira como a saúde e a ludicidade são compreendidas e orientadas nas práticas instituídas por essa Cartilha. Trata-se de uma pesquisa documental que utilizou a análise de conteúdo, construindo as seguintes categorias: “Saúde, Felicidade e Higiene” e “A Ludicidade em busca da Saúde”. Diante dos resultados encontrados, identificamos práticas que impunham, de certa forma, à população, uma padronização nas atitudes para que se obtivesse saúde. Tais atitudes influenciavam em todos os campos do contexto social, a saber: relações sociais, o lazer, os ambientes familiares, as escolas. Destacamos ainda  que a alegria pura e livre contida nos espaços de lazer e nas horas lúdicas parecem estar sendo sempre vigiadas. O que nos faz apontar a necessidade de refletirmos sobre a naturalização dessas ações ainda nos dias atuais.

Published: March 2020

Background. Gaucher disease (GD) is a rare hereditary condition, which represents the most common form of lysosomal storage diseases. Enzyme replacement therapy (ERT) with recombinant glucocerebrosidase is used for the treatment of type 1 and type 3 GD. Imiglucerase (recombinant glucocerebrosidase) is the ﬁrst biotechnological ERT medication possessing conﬁrmed clinical efﬁcacy and safety.

Aim. To compare the efﬁcacy and safety of the biosimilar drug Glurazyme and the reference drug Cerezyme during ERT therapy in patients with type 1 GD.

Materials and methods. Thirty patients aged from 19 to 63 years (33 ± 9.7 years) with a stable course of type 1 GD were enrolled in the study. The patients were randomly divided into two equal treatment groups, one of which received Glurazyme and the other received the reference drug Cerezyme. In both groups, the drugs were used in doses of 15–40 U/kg intravenously once every 14 days for 52 weeks.

Results. At the end of the study, at week 52 (primary endpoint of efﬁcacy), both groups demonstrated a similar increase in hemoglobin concentration compared to the baseline data. In both groups, the average increase in hemoglobin concentration was 4.8 g/l, with this parameter varying between the groups by 0.1 g/l. At week 52, the calculated 95% conﬁdence interval for the difference in hemoglobin concentration did not cross the non-inferiority margin of 18 g/l, which had been speciﬁed as the lower level of drug efﬁcacy. This led to the conclusion that the studied drug Glurazyme is not inferior to Cerezyme in terms of efﬁcacy. A comparison of the treatment groups by secondary endpoints of efﬁcacy revealed: no decrease in hemoglobin concentration by more than 20 % in both groups; no differences between the groups by the number of patients with a change in platelet concentration relative to the baseline values; no increase in the spleen and liver volume by more than 20 and 10 %, respectively, in both groups. The doses of the drug under study and the reference drug remained unchanged during the research. The concentration of chemokine CCL-18 decreased slightly in 10 patients (64.3 %) and 6 patients (40 %) in the Glurazyme group and the Cerezyme group, respectively. The proportion of patients with improved physical and mental health components was 57.1 and 57.1 %, respectively, in the Glurazyme group compared to 73.3 and 60 %, respectively, in the Cerezyme group. Changes in the state of the bone tissue and the reserves of accumulated metabolites in the bone marrow showed a similar decrease in the severity of bone marrow inﬁltration in both groups.

Conclusions. Glurazyme and Cerezyme showed comparable parameters of efﬁcacy and safety in patients with GD type 1 during long-term enzyme replacement therapy.
Features of immunohematological and hematological parameters of a donor with a rare phenotype -D-
Authors: Lamzin I. M. , Sokolova M. N. , Khayrullin R. M. , Mineeva N. V. , Khapman M. E.
Published: March 2020

Background. This study is devoted to a rare variation of the -D- phenotype . The -D- phenotype was ﬁrst discovered by R. Race, R. Sanger and J.G. Selwyn in 1951. In Russia, the phenotype -D- was ﬁrst discovered by V. Morokov in 1985. Typically, the -D- phenotype is detected when physicians examine post-transfusion complications or hemolytic disease of the newborn, since such patients demonstrate high antibody titres to absent antigens. In the present study, the -D- phenotype was detected in a primary blood donor at the clinical laboratory of the Ulyanovsk Regional Blood Transfusion Station (Ulyanovsk, Russia). Aim. To study speciﬁc features of immunohematological and hematological blood parameters in a donor with a rare variation of the -D- phenotype.

Materials and methods. The detection of the -D- phenotype by immunohematological methods was carried out using automatic analysers. Molecular DNA typing was used to conﬁrm the -D- phenotype. The shape of erythrocytes of the donor with the -D- phenotype was evaluated using an atomic force microscope. The characteristics of the erythroid lineage were studied using an automatic hematological analyser.

Results. The -D- phenotype was detected in a primary blood donor. Due to the extreme rarity of the -D- phenotype and the lack of programmed algorithms, the validation of the results by automatic analysers was incorrect. Of critical importance was the visual assessment of gel ID cards by the medical staff. Genotyping conﬁrmed the lack of C, c, E, e, Cw speciﬁcities in the RHCE gene. The hematological parameters of the donor were within the age norm. An assessment of the image of a cytological blood preparation did not reveal changes in the shape of erythrocytes and their size.

Conclusions. The primary determination of the -D- phenotype using automatic immunohematological analysers can be complicated by the impossibility of validating the results, the incorrect operation of the installed software and the need for expert evaluation of blood samples by the staff. The presented case of the -D- phenotype was not associated with changes in the shape of erythrocytes and blood hematological parameters.

Authors: Goncharov A. A. , Rybka M. M. , Khinchagov D. Ya. , Rogalskaya E. A.
Published: March 2020

Background. Protein C deﬁciency is a rare condition. However, this pathology occurs more frequently in premature babies with cyanotic heart disease.

Aim. To present a clinical case of an intraoperative detection of protein C deﬁciency in a patient operated for cyanotic heart disease.

General ﬁndings. A clinical case of an intraoperative recurrent thrombosis of systemic-to-pulmonary shunts in a newborn patient with cyanotic heart disease is described. Newborn and premature babies with cyanotic heart defects belong to a high risk group of developing intraoperative thrombosis due to a deﬁciency of natural anticoagulants, which can occur as a result of genetically conditioned protein C deﬁciency, prematurity, immaturity of the liver or its reduced synthetic function, heart failure and hypoxemia. Additional pre-operative screening is required for detecting a deﬁciency of natural anticoagulants in this group of patients. The hospitals that perform such surgery should be equipped with protein C concentrates.

This commentary provides an update to the last situation of 2019 novel coronavirus pandemic (COVID-19) in the world. Current known evidence for COVID-19 suggests that we are now faced with the most virulent coronavirus and epidemic that the world has ever seen. The coronaviruses already identified such as severe acute respiratory syndrome coronavirus, Middle East respiratory syndrome coronavirus, and nowadays COVID-19, may only be the tip of the iceberg, and probably more novel and severe zoonotic infections might be revealed in the near future in the humans' populations. However, in this pathway, the important issue that often has been neglected is the change and reforming of the person's lifestyle and eating habits.

Authors: Hancu Gabriel , Gyeresi Arpad , Gaspar Attila
Published: March 2020

The aim of this work is to elaborate a fast and reliable capillary electrophoresis method, for the separation of 1,4-benzodiazepine (BZD) derivates and their degradation products in acidic medium and in UV light. Because BZDs are neutral, hydrophobic compounds, the most efficient method proved to be micellar elektrokinetic capillary chromatography (MECC). For the separation we used a sodium tetraborate buffer with tensioactive agent (sodium dodecyl sulphate - SDS) and an organic modifier (methanol). We also optimized the analytical conditions, and studied the effects of the SDS and methanol concentrations and buffer pH on the determination efficiency.

Authors: Sarbu Costel , Pop Horia F. , Elekes Raluca-Stefania , Covaci Georgeta
Published: March 2020

Discriminant analysis was applied as a method of disease identification, using data obtained from blood analysis of several patients. The investigated compounds in human blood samples were organic compounds of clinical interest (glucose, triglycerides, cholesterol, creatinine and urea), inorganic compounds (Na, K, Ca, Mg and Fe) and enzymes (Lactate Dehydrogenase (LDH), Alanine Transaminase (ALT), Aspartate Aminotransferase (AST), Alkaline Phosphatase (ALP) and Gamma Glutamyltransferase (GGT)). According to their concentration level the following diseases have been selected for study: hydroelectric disorders, hepatic diseases, lipid disorders, diabetes and renal disorders. Some patients resulted to be healthy. Discriminant analysis was not only used for classifying the patients according to their disease but also for detecting the most important variables that discriminate between the groups. For example it has been found that the greatest contribution to the discriminatory power of the model is given by glucose (l* = 0.263; F = 44). The obtained results confirm that clinical analysis combined with the multidimensional interpretation of data gives an interesting and very useful way of disease correlations, interpretations, problem solving and cost effectiveness.

Authors: Badea Irinel Adriana , Vladescu Luminita , Dumitrescu Valerica , Marin Lucia , Capota Petre
Published: March 2020

In this paper the heterogeneous equilibriums between the reagent a-benzoine-oxyme and molybdenum were studied. We have studied the influence of pH, the solvent composition as well as the use of mixed solvents, the nature and concentration of acids, bases and also the nature of the cations that can be present in the solution obtained as a result of the 99Mo production using a low enriched uranium metal-foil target. It was proven that molybdenum can be selectively and quantitatively separated starting from acidic solutions in which Ru, Rh, Cu, Ni and Zn are present. The quantities of Mo, Ru and Rh were determined by optical emission spectroscopy coupled with direct coupled plasma (DCP-OES) and those of Cu, Ni and Zn by optical emission spectroscopy coupled with inductively coupled plasma (ICP-OES).

Three Cu(II) complex compounds with 4-methoxybenzaldehyde-2-benzothiazolyl hydrazone(HL) have been prepared and characterized by elemental and thermogravimetrical analysis, infrared, electronic and EPR spectra. The complex compounds have various composition and stereochemistry, depending on the reaction conditions and the metal salt used. The ligand acts as neutral bidentate NN donor in the complexes [Cu(HL)2(H2O)2] . Cl2 and [Cu(HL)2(H2O)Br] . Br and monobasic bidentate donor in the complex [Cu2L4]. EPR studies of the complexes gave axial symmetry, with dx2-y2 the ground state. The bonding parameters calculated from the electronic and EPR spectra indicate strong in-plane p-bonding for all the complexes. Investigations on antibacterial and antifungal activities show that the complexes are more active than the free ligand.

Authors: Feroiu Viorel , Geana Dan , Partenie Octavian
Published: March 2020

A cubic equation of state, GEOS, with quadratic mixing rules and two adjustable parameters was used to calculate the solid � gas equilibrium in aromatic compounds + supercritical carbon dioxide systems. The results are in good agreement with the experimental data for temperatures between 308 K and 343 K and pressures up to 360 bar. The adjustable parameters kij and lij used in the mixing rules vary linearly with the temperature or remain constant for the investigated systems. Based on this observation, the binary interaction parameters and hence, the solubilities of the studied solid aromatic compounds in supercritical carbon dioxide can be predicted.

Experimental results obtained with a sodium tetraborohydride (SBH) fuel cell equipped with a Nafion 117 membrane are presented in this paper. For both electrodes, anode (Pt-Ru/C) and cathode (Pt/C), the same catalyst loading of 1 mg cm-2 has been used. The increasing of performance has been realized by the optimization of the operating parameters: temperature, SBH concentration, reactants flow and oxidant nature (air or oxygen). In order to increase the contact region between reactant � catalyst layer � membrane, with a favourable effect on fuel cell performance, the Nafion 117 was added in the catalyst layer. Maximum power density of over 74 mW cm-2 has been achieved at 100�C with oxygen as oxidant.

Published: March 2020

This paper presents the characterization of carbonic functional phase based on carbon mesophase/carbon nanotubes nanocomposites used as functional filler in a polymeric matrix by optical microscopy, X-ray diffraction and functional by electrical resistivity measurements. The nanocomposites were prepared by adding of single walled carbon nanotubes (SWNT) or multi walled carbon nanotubes (MWNT) in a petroleum pitch. It was reported that SWNT behaves as either a metal or a semiconductor depending on the wrapping angle of the graphene sheet and its diameter, while MWNTs are always conductive. Carbonic functional phase was obtained by heat treatment of pitch/nanotubes mixtures at 450oC and 900oC temperatures. Polymeric composites were obtained by adding carbonic functional phase in an epoxy resin matrix. The polymeric composites were functional characterized from electrical point of view, establishing their behaviour.
The electrical behaviour of the (SWNT/MWNT)/PP systems heat treated at 450�C is not largely influenced by the CNTs, because they are not creating any conducting connections. The composite systems, heat treated at 450�C, show a high resistivity of 105 ohm�cm, while the systems heat treated at 900�C show a lower electrical resistivity of 10-1 ohm�cm.

The mechanism of the enzymatic iodination process of diethylmaleate and diethylfumarate (which present no miscibility with water) in the presence of lactoperoxidase, both in diluted hydrogen peroxide solution and in a generating system of hydrogen peroxide using ammonium and calcium iodides as halide sources in disperse system (after an ultrasonic pretreatment) was studied. The obtained sole product (diethyl-2, 3-diiodosuccinate) after the enzymatic iodination process was directly hydrolyzed to a tartaric acid present in an optically inactive form. The mechanism of obtaining the intermediate and final products and respectively, the existence of both D, L-tartaric acid and meso-tartaric acids (as lithium bitartrates) were also investigated.

Published: March 2020

This paper presents the molecular encapsulation of some odorant compounds in a- or b-cyclodextrin. The molecular encapsulation of hydrophobic compounds in these natural cyclic oligosaccharides provides powders at nano scale with very good protection against degradative environmental factors (temperature, light, moisture, air/oxygen), controlled release of the bioactive compounds (long life bio-action), easy handling of powdery complexes (containing bioactive liquid compounds), higher water soluble bioactive specialties (containing hydrophobic biocompounds). From this point of view, some odorant bionanoparticles with enhanced bioactive properties (protection against oxidation, enhanced olfactive and long life smelling properties) and possible applications in cosmetic and toiletries were obtained and characterized. Both limonene and linalool enantiomers (d and l), dl-linalyl acetate, b-caryophyllene, benzaldehyde, g-decalactone, a-ionone, menthol, vanillin, and hydroxycitronellal were used as guest compounds. The encapsulation was achieved by crystallization from the ethanol-water solution. The GC-MS was used for odorant compound analysis and TG for nanoparticle analysis. a- Cyclodextrin release the odorant compounds earlier then the b-cyclodextrin, as indicated by thermogravimetric analysis. The benzaldehyde, menthol and vanillin were decomplexed at lower temperatures then 70�C and the majority of compounds were complexed at 1:1 stoichiometry ratio.

Published: March 2020

The adsorption of cetylalkyl pyridinium and alkyloxyethylene pyridinium chlorides at the silica-alumina water interface at ph =7 and 25 0C was analyzed to determine the type of interaction between surfactant molecules and solid substrat between adsorbed adiacent molecules and with the surfactant molecules in the equilibrium water solution. The experimental adsorption isotherm for the entire concentration range consists of four regions with the maximum adsorption attained at the critical micelle concentration of each surfactant in aqueous solutions. Different models and equations of adsorption suitable to describe different types of forces implicated in adsorption of cationic surfactant at the opposite charged solid surfaces were applied. The free energy of adsorption, free energy of hydrophobic interaction and mean surface aggregation number were calculated. Insertion of oxyethylene groups leads to the increase of the hydrophobicity of these cationic surfactants. From the calculated free energy of adsorption through electrostatic and van der Waals interactions different surface structures were attributed to each region: neutralization of electrical charges, formation of hemimicelles, admicelles and bilayers.
Effects of Nanoparticle Clustering on the Heat Transport in Nanofluids Through Fractal Theories

Published: March 2020

Considering that the motion of microphysical object takes place on continuous but non-differentiable curves, i.e. on fractals, effects of nanoparticle clustering on the heat transfer in nanofluids using the scale relativity theory in the topological dimension are analyzed. In the one-dimensional differentiable case, the clustering morphogenesis process is achieved by cnoidal oscillation modes of the speed field and a relation between the radius and growth speed of the cluster is obtained. In the non-differentiable case, the fractal kink spontaneously breaks the vacuum symmetry by tunneling and generates coherent structures. Since all the properties of the speed field are transferred to the thermal one and the fractal potential (fractal soliton) acts as an energy accumulator, for a certain condition of an external load (e.g. for a certain value of thermal gradient) the fractal soliton breaks down (blows up) and releases energy. As result, the thermal conductibility in nanofluids unexpectedly increases.

Published: March 2020

Methanol extracts prepared from Ziziphus and Hydrangea fruits and leaves were examined for their antioxidant activity. Antioxidative activities were studied in sunflower oil at 980C, by measuring peroxide value, and with the spectrophotometric method, which uses 1, 1 diphenyl-2-picrylhydrazyl (DPPH) free radicals. The relationship between the structural characteristics of pure four flavonoids and their antioxidant activity was also studied. The obtained results suggest that the free radical scavenger potential of these polyphenolic compounds closely depends on the particular substitution pattern of free hydroxyl groups on the flavonoid skeleton.
Reduced Modular Representations Applied to Simulate Some Genetic Regulatory Circuits**
Authors: Maria Gheorghe
Published: March 2020

General chemical engineering modelling principles are valuable tools to represent the topology and the kinetics of complex cell processes. Elaboration of reduced models is based on a large amount of qualitative-quantitative information �translated� from the �language� of molecular biology to that of mechanistic chemistry. In the �reverse engineering� approach, linked modules of adjustable complexity are used to simulate the genetic expression regulatory networks by adequately lumping of species or metabolic reactions exhibiting similar functions. The resulted model must keep a satisfactory predictability on key-species and steps, an adequate representation of species inter-connectivity, structural, functional, and temporal cell hierarchy, and of the multi-cascade control loops of adjustable intermediate levels. Application of (non-) conventional identification and lumping methods can lead to a satisfactory prediction of local and global properties of the protein synthesis regulatory network. Examples on modelling the genetic expression illustrate the advantages but also the over-simplifications introduced by various reduced modular representations. Potential applications of the lumped simulation in `genetic circuit engineering` reveal the advantages of using modular constructions for �in-silico� design of new organisms that possess desired specific functions (e.g. biosensor design).
The Influence of Iron on the Colour of Red Wines
Authors: Alecu Aurora
Published: March 2020

The antochians are the pigments responsible of the color of the young red wine[ 7 ]. Among the antochians, the malvidine has the most important role in the coloring of the red wines. On its stability depends to a great extent the colouring tint and the sensorial particularities of the red and rose wines coming from various vineyards [8]. In the presence of the oxygen and of the iron, the malvidine suffers a degradation process, determining the depreciation of the wines [1; 3; 5]. In this paper was studied the malvidine-3-glucoside degradation kinetic, in model solutions of synthetic wine, in the presence of different concentrations of iron, at 70o C and two values of pH characteristic for the wines (2.9 and 3.4).

Interactions between metal ions and biological systems have many implications. Based on these facts, several platinum compounds have been obtained and evaluated as chemotherapeutical agents. It is generally believed that the anticancerous effects of cis-platinum are based on interactions with DNA. Our study is trying to reveal the interrelations between concentration of some metallic ions from hepatic tissue and different doses of cis-platinum (cDDP). The cytotoxic activity of cis-platinum can be correlate with the levels of platinum that bounds to DNA. For the experimental part, we used adults animals from Wistar rats strain divided in four experimental groups and one control group. Wistar rats from the experimental groups were injected intraperitoneally (i.p.) with cis-platinum (the drug called Sin-Platinum) in study days 3 and 8. The animals from control group were injected with saline solution (placebo), also in study days 3 and 8. The results showed that the concentration of metal ions in liver is modified proportionally with administrated doses.
