Published: May 2019

A method for copper(II) determination based on copper(II) ions interaction with the organic reagent picramine-ε, concentrating the formed complex on a solid-phase matrix and recording diffuse reflectance spectroscopy spectra by a portable combined LED miniphotometer was developed. Poly-ε-caproamide membranes were investigated as solid-phase matrixes. It was found that the diffuse reflectance coefficient of the studied membranes in the visible spectrum region does not depend on wavelength. So, the signal from membranes does not distort the results of the analysis. Factors controlling the process of sorption of the copper(II) complex with picramine-ε were studied. It was shown that the poly-ε-caproamide membranes are effective sorbents which provide the possibility of concentrating the analyte at a level higher than 105. The dependences of analytical signal on the acidity of the solution, the time of keeping the complex in the solution and the initial volume of the solution passed through the membrane were studied. Based on the obtained data, the optimal conditions of the analysis were found. Calibration dependence of the analytical signal on the concentration of copper(II) in model solutions was estimated. The method was tested for the determination of copper(II) ions in white wine. The method of additives was used for the analysis. It was found that the concentration of copper(II) ions in “Vagrus” wine is 0.0016 mkg/ml.
The Formation of Deposits on the Walls of the Pores in the Filtering Process
Authors: Taran Yu. A. , Kozlov A. V. , Taran A. L.
Published: May 2019

The aim of the work is to consider the mechanism of clogging the pores of the filter unit by small particles from the flow of filtrate inside them. Theoretical ideas about the process of filtering with the deposition of small particles from the filtrate on the pore walls and attribution of its fundamentals to restructuring from the original structure to the final structure allow to describe the process of clogging the pores using well studied concepts of known processes with phase transformations (in particular, crystallization). Based on this analogy and the approach to the description of the transformation of the "old" structure into a "new" one in time, using experimental data and their processing we calculated the rate of nucleation of the sediment centers (ωnucl), the linear (υlin) and volumetric rates of sediment plaques growth in the pores of the filter unit at different values of the process driving force, at different pressure difference in the system, and at different concentrations of solid particles in the suspension. Interpolation and extrapolation dependences were obtained for analyzing the mechanisms of sediments formation and growth for determining and calculating these (ωnucl, υlin) rates. Using the concepts of nonequilibrium thermodynamics to assess the influence of the driving forces we studied their influence (changes in the concentration of solid particles in the filtrate suspension and pressure drop across the filtering layer) on the dynamics of the filtration process. Using the data obtained it is possible to find the degree of clogging of through pores, which determines the filtration conditions, the filter septum type, and the filter overall dimensions.
Development of Reaction-Rectification Process of Obtaining Mesityl Oxide. II. Analysis of Statics and Modeling of the Process
Authors: Yakhyaev M. A. , Gutenkov V. S. , Cardona C. A. , Pisarenko Yu. A.
Published: May 2019

Using the results of an earlier study of the physicochemical properties of the reaction system of the process of producing mesityl oxide, an analysis of the statics of the combined variant of the organization of this process was carried out. It is shown that of practical interest are the modes of the process corresponding to the first specified separation. In this case, the limiting stationary states, characterized by the maximum acetone conversion, selectivity, and the yield of the target product — mesityl oxide, are distinguished. The possibility of practical implementation of the limiting stationary state of the reactive distillation process for producing mesityl oxide, which provides almost complete conversion of acetone with a yield of mesityl oxide approaching 100%, has been proved. The limit stationary state corresponds to the reaction-distillation process with the selection of a single product stream. For the mode of carrying out the combined process that corresponds to the selected limiting stationary state, a schematic flow chart for the production of the target product has been proposed. By means of computational research, it has been established that the most rational option for organizing a reaction hub is to use a single apparatus in it — the reaction-distillation column. In the Aspen Plus® software package, a process model was constructed that corresponded to the proposed technological scheme and through a computational experiment, its structural and parametric optimization was carried out. As a result, the static parameters of the technological system were established, as well as the characteristics of the apparatuses, allowing to obtain the required quality product in the reactiondistillation column. output, approaching 100%. It has been shown that when modeling a chemicaltechnological system, it is necessary to use different sets of parameters of the basic equation used to describe phase equilibrium. Thus, for calculating reactive distillation and distillation columns, the liquid – vapor phase equilibrium parameters for the mesityl oxide–water system should be used, and when calculating the Florentine vessel for this mixture, it is necessary to use the parameters corresponding to the liquid – liquid equilibrium. The use of a single set of parameters of the basic equation leads to significant errors and inadequate description of the process of producing mesityl oxide by condensation of acetone.

Published: May 2019

The dispersion composition of polymer suspensions and molecular weights of polymers obtained by suspension polymerization of MMA in the presence of polymer surfactants – methylmethacrylate and methacrylic acid copolymers – were studied. It is shown that a highly dispersed fraction of particles with diameters of 0.02–2.0 µm and a fraction of particles with large diameters (up to 1000 µm) are always present in the polymer suspension. After fractionation of polymer suspensions 3 fractions of particles with different diameters were obtained. For each particle fraction the molecular masses of polymers were determined by viscometry. A significant difference in the values of the molecular masses of polymers obtained as particles of small and large diameters – 105 and 106 Da, respectively – is shown. The presence of a highly dispersed fraction of particles in which a polymer of high molecular weight is formed has a noticeable effect on the average molecular weight of the polymer. In particles of small diameter polymerization takes place according to a mechanism close to the emulsion, due to the fact that the volume of such particles contains a small amount of radicals. The high rate of polymerization leads to the formation of a polymer of high molecular weight, the appearance of a gel effect and a decrease in the termination constant. In most particles, polymerization proceeds by a mechanism close to the solution polymerization, and polymers of low molecular weight are formed. This makes it possible to synthesize polymers of a given molecular weight in drops of certain dispersity.
Self-Regulating Electrically Conductive Materials Based on Polyethylene Compositions with UHMWPE and Carbon Black
Authors: Markov A. V. , Chizhov A. S.
Published: May 2019

Electrically conductive composites based on high density polyethylene (HDPE) / ultrahigh molecular weight polyethylene (UHMWPE) blends filled with carbon black were studied. The work is a part of the research of electrically conductive materials for the manufacture of self-regulating polymer heaters. In this work, the authors investigated composites based on HDPE/UHMWPE (molecular mass of ~ 7 million) blends filled with carbon black (average particle size ~ 20 nm). The goal of the work was to obtain a self-regulating electrically conductive polymer material with optimal thermoelectric characteristics and high heat resistance. It was shown that the effect of adding UHMWPE to the HDPE/carbon black composites on the thermoelectric behavior of the resulting material was similar to cross-linking. This reduced the undesirable effect of the negative thermal coefficient (NTC) of the electrical resistance. In addition, the heat resistance of the material at elevated temperatures was increased. This makes it possible to exclude the radiation or chemical cross-linking in the manufacture of self-regulating polymer heating elements. The rheological, mechanical and thermoelectric properties of HDPE/carbon black composites modified with UHMWPE were also studied. It was found that a diffusion interphase layer with a reduced fluidity in the melt of HDPE/UHMWPE blends was formed. It was established that self-regulating composites containing 30–40% of UHMWPE had the best operational properties. We can recommend the methods of extrusion and injection molding for the processing of HDPE/carbon black composites mixed with 30% UHMWPE, and the pressing method in case of UHMWPE content of 40%. The ability of the composites to be molded is sharply reduced at higher contents of UHMWPE.

Published: May 2019

The article deals with the results of experimental studies on statistical processing of diffraction spectra of solid drugs for the purpose of their separation and identification. Diffractograms of the original and falsified drugs Arifon were used for the study. They were obtained on a desktop diffractometer Difray 401 produced by Scientific Instruments Inc. (Saint Petersburg, Russia). The research was conducted in the Scilab environment distributed under a free license. The captured diffraction spectra were processed using a smoothing procedure that eliminated the influence of a random component in the original data. Analysis of the results of smoothing by the moving average method showed that the smoothing algorithm with the window 41 point is most preferable. The results of statistical processing of diffractograms of the drugs investigated by the principal component analysis (PCA) in graphical and numerical form, which showed good convergence and efficiency of this method in the separation of diffraction spectra, are presented. The conducted studies make it possible to create a technique that allows identifying solid drugs by X-ray diffraction.

Authors: Nguyen Dong Van , Vo Binh Thai , Dinh Phuc Van
Published: May 2019

The capability of chitosan-based MnO2 material for retention of arsenate in water was investigated for static and dynamic models. Several factors that influence the retention capacity of the material for As(V) such as pH, adsorption time, initial concentration of As(V), mixing speed (static) and competitive anions were studied. The results showed that the maximum adsorption capacity calculated from Langmuir model of As(V) on MnO2/chitosan was lower than that of chitosan (3.33 mg As/g compared to 12.5 mgAs/g). However, the retention efficiency for As(V) at low concentration (300 ppb) of MnO2/chitosan was much better than chitosan (>99% compared to 81%). MnO2/chitosan material worked with As(V) within pH range of 3.06 – 9.13 with best efficiency within pH range of 3–4. Chloride, nitrate and sulfate anions at concentrations of 8000–10000 mg/L reduced 20% retention efficientcy of As(V). The studied material showed its great promise to be useful for As(V) removal from water

Authors: Nguyen Tien Anh , Nguyen Hoi Thi
Published: May 2019

Nanomaterials of cobalt ferrite (CoFe2O4) doped with zinc have been synthesized by co-precipitation using KOH solution of 10-4 M as a precipitant. The effect of zinc contents and calcination temperature on the structure and magnetic properties of Co1-xZnxFe2O4 were studied. The parameters of the crystalline cubic lattice (a ~ 8.4 Å) and the crystalline size (d = 20–30 nm) increased with increasing the calcination temperature and zinc content in the samples. However, the remanent magnetization, saturation magnetization, coercive force and M at the maximum field decreased with increasing the zinc content. The nanomaterials of cobalt ferrite doped with zinc have Hc values in the range of 8.67–179.63 Oe, Mr values in the range of 1.33–16.90 emu/g, which are quite smaller than those of original CoFe2O4 material (Hc=497.89 Oe, Mr=36.29 emu/g); moreover, the nanomaterials prepared have Ms values in the range of 56.00 – 99.97 emu/g, which are similar to those of original CoFe2O4 material (Ms= 88.67 emu/g) and are quite higher than those of original ZnFe2O4 material (Ms ~ 1.2 emu/g).

Published: May 2019

A hyphenated system for methylmercury based on a gas chromatograph (GC) coupled with an atomic fluorescence spectrometric (AFS) detector equipped with an online purge and trap as a preconcentrator was made. Operating parameters for the whole system were optimized and analytical performances of the system are verified by quality control chart for stability. Organomercurial compounds in an aqueous sample were in-situ ethylated and purged to a trap in-line with a separation device instead of conventional off-line solvent extraction. A 100 mL aqueous sample containing methylmercury in an impinger was mixed with sodium tetraethylborate at pH 5.0. The forming volatile ethylmethylmercury was purged for 30 minutes with the assistance of an Ar flow and trapped into a Tenax sorbent. The trap was then heated to release volatile compounds including ethylmethylmercury into a GC-AFS for separation and detection. The instrumental detection limit was 4.8 pg Hg/L. The method can therefore be applied for the determination of methylmercury in water samples at ultra – trace.

The Iraqi economy has suffered and continues to suffer the burden of inheritance from the previous phase of more than half a century. The study aims at illustrating the economic openness in Iraq and searching its destructive results and impacts on the society. The importance of the research lies in discussing a significant and contemporary issue that has social and political impact represented by the economic openness and its reflection on the Iraqi economy and its role in disabling the process of development. Results showed that Economic openness is a major obstacle to economic development because of the direct and negative impact of investment, as well as the country’s distortion of spending and the reduction of state revenues, as well as the delay of approved projects, The state has not yet established serious mechanisms to solve the problems facing it, but all that happening is attempts to deal with problems temporarily without going to the causes of the problem to deal with them and develop solutions to them and The decline in the contribution of the economic sectors such as the agricultural and industrial sectors to the gross domestic product, as well as the clear deterioration of all services (municipal, health, education, electricity, water, etc.).

Authors: Palacio Fierro Andres , Calderón Alejandro , Revelo Renato
Published: May 2019

La corrupción es sinónimo de pobreza y retraso en general para la sociedad que la contiene, siendo en estos lugares donde este problema público, muchas veces, opera desde altos niveles, a través de autoridades que detentan poder político y/o económico, circunstancia que es aprovechada por grupos de interés para crear normativas que privilegie su beneficio en detrimento del interés general. Por tal motivo, el objetivo de este trabajo es brindar una propuesta que no se enfoque únicamente en cambios institucionales o normativos para atender este problema, ya que este asunto persiste a pesar de reformas administrativas o legales. En este sentido, este trabajo plantea una alternativa que permitan anticiparse y controlar la corrupción desde su raíz. Método. La fuente principal de la información será documental, a través de instrumentos de recolección bibliográfica, siendo el “análisis” el procedimiento para el tratamiento de la información recolectada. Resultados. La propuesta se sustenta en la formación de comisiones ciudadanas para la transparencia y anticorrupción, para que sean aquellas quienes sirvan de apoyo para controlar la corrupción de las principales instituciones u organismos estatales. Estas comisiones operarán bajo un método cuyo proceso tiene los siguientes pasos: diagnóstico del organismo público, gestión de riesgos, planeación, articulación, comunicación interna, controles, auditoría de gestión, medición y mejora. Conclusión. Los resultados y la propuesta de este artículo no son definitorios, sino más bien pretenden abrir ciertas líneas de discusión para futuras investigaciones y aplicaciones.

This study is trying to shed some lights on the ways that entrepreneurship intentions are developed. Depending on the Theory of Planned Behavior (TPB) the study tries to trace the effect of Omani Higher Education Institutions (HEIs) student’s attitudes towards entrepreneurial intentions to start-up. Practical analysis has been carried out on a sample of (2123) HEIs’ students of Oman. Through self-administered questionnaire, the data was collected and analysed using appropriate statistics tools. Hypothesis was tested and correlation matrices were developed to test the correlations between these two variables. The results show that the entrepreneurial attitudes of HEIs’ students in Oman positively related to their entrepreneurial intentions. This relationship between attitudes and intention was measured and it was found that the amount of variation in students’ intentions that is accounted for attitudes is 55 percent. The F ratio is found large 2550.7, which reflects the greater variation in intention that is explained by attitudes.
Spiritual Meaning of Placenta Disposal

The placenta was expelled after childbirth. Major functions of the placenta include the exchange of metabolites between the mother and the fetus, gas exchange, and immunological support for the fetus. How is the placenta, which played an important role in the development of the fetus, treated after its expulsion?

In Japan, a regulation implemented in 1948 ensures that designated operators incinerate placentas. However, prior to its enactment, various procedures has been implemented to dispose them. During the 8th - 12th centuries, placentas was placed in an unglazed pot or wrapped in hay, and buried either on a mountainside or under the floor of a building. Before burial, placentas were also covered with salt or alcohol.

The number of foreign residents has been rapidly increasing in Japan. In 2016, there were a total of 290 people living with resident visas, which is the highest number since1956 [1]. Although the majority of foreign residents are Chinese, Filipino,or Brazilian, the number of residents from Vietnam, Thailand, Nepal, and Indonesia has also been increasing rapidly over the last two decades [1]. These residents primarily exhibit health issues that involve noncommunicable diseases and occupational health problems, which is occur as a result of the fact that most of them have engaged in extended physical labor and are also senior citizens.

Antibody-derived chimeric antigen receptor (CAR) T cell therapy has achieved gratifying breakthrough in hematologic malignancies but has shown limited success in solid tumor immunotherapy. Monoclonal antibody, TAB004, specifically recognizes the aberrantly glycosylated tumor form of MUC1 (tMUC1) in all subtypes of breast cancer including 95% of triple-negative breast cancer (TNBC) while sparing recognition of normal tissue MUC1. We transduced human T cells with MUC28z, a chimeric antigen receptor comprising of the scFv of TAB004 coupled to CD28 and CD3ζ. MUC28z was well-expressed on the surface of engineered activated human T cells. MUC28z CAR T cells demonstrated significant target-specific cytotoxicity against a panel of human TNBC cells. Upon recognition of tMUC1 on TNBC cells, MUC28z CAR T cells increased production of Granzyme B, IFN-γ and other Th1 type cytokines and chemokines. A single dose of MUC28z CAR T cells significantly reduced TNBC tumor growth in a xenograft model. Thus, MUC28z CAR T cells have high therapeutic potential against tMUC1-positive TNBC tumors with minimal damage to normal breast epithelial cells.

With the aim of assessing the effects of beneficial microorganisms on greenhouse tomato “plum” grown under salinity conditions, research was carried out in southern Italy from summer to winter, by comparing two arbuscular mycorrhizal fungi (AMF) based formulates (Rizotech Plus, Myco Apply DR) and a non-inoculated control, in factorial combination with four soil electrical conductivities (1.5, 3.0, 4.5, 6.0 mS·cm−1 EC). The highest root colonization was 83% at 3.0 mS·cm−1 under AMF-based treatments and 34% at 1.5 mS·cm−1 in non-treated control; the latter attained lower values than AMF treatments at any soil EC. Harvest occurred 3.5 days earlier in control plants, six days earlier under 6.0 mS·cm−1 EC compared to 1.5 mS·cm−1. The inoculated plants always showed higher yield than the control ones and the highest production at 4.5 mS·cm−1 EC; control plants attained the highest yield under 3.0–4.5 mS·cm−1 EC. The highest values of most fruit quality indicators, mineral elements and antioxidant compounds and activity were recorded under AMF-based formulates inoculation and 6.0 mS·cm−1 soil EC. Beneficial microorganisms proved to be an effective environmentally friendly tool for improving tomato yield and quality performances in both normal and soil salinity conditions.

Background: Immunotherapy for multiple myeloma (MM) has been the focus in recent years due to its myeloma-specific immune responses. We reviewed the literature on non-Food and Drug Administration (FDA) approved monoclonal antibodies (mAbs) to highlight future perspectives. We searched PubMed, EMBASE, Web of Science, Cochrane Library and ClinicalTrials.gov to include phase I/II clinical trials. Data from 39 studies (1906 patients) were included. Of all the agents, Isatuximab (Isa, anti-CD38) and F50067 (anti-CXCR4) were the only mAbs to produce encouraging results as monotherapy with overall response rates (ORRs) of 66.7% and 32% respectively. Isa showed activity when used in combination with lenalidomide (Len) and dexamethasone (Dex), producing a clinical benefit rate (CBR) of 83%. Additionally, Isa used in combination with pomalidomide (Pom) and Dex resulted in a CBR of 73%. Indatuximab Ravtansine (anti-CD138 antibody-drug conjugate) produced an ORR of 78% and 79% when used in combination with Len-Dex and Pom-Dex, respectively. Conclusions: Combination therapy using mAbs such as indatuximab, pembrolizumab, lorvotuzumab, siltuximab or dacetuzumab with chemotherapy agents produced better outcomes as compared to monotherapies. Further clinical trials investigating mAbs targeting CD38 used in combination therapy are warranted.
Improving Computational Efficiency in Crowded Task Allocation Games with Coupled Constraints
Authors: Lim Ming Chong , Choi Han-Lim
Published: May 2019

Multi-agent task allocation is a well-studied field with many proven algorithms. In real-world applications, many tasks have complicated coupled relationships that affect the feasibility of some algorithms. In this paper, we leverage on the properties of potential games and introduce a scheduling algorithm to provide feasible solutions in allocation scenarios with complicated spatial and temporal dependence. Additionally, we propose the use of random sampling in a Distributed Stochastic Algorithm to enhance speed of convergence. We demonstrate the feasibility of such an approach in a simulated disaster relief operation and show that feasibly good results can be obtained when the confirmation and sample size requirements are properly selected.

Published: May 2019

In this study, different carob extract-based media containing Medium A (included all ingredients), Medium B (included yeast extract and salts), Medium C (included (NH4)2SO4 and salts), Medium D (included only salts) and Medium E (included no ingredients) were evaluated for ethanol fermentation by Saccharomyces cerevisiae in a biofilm reactor and their results were used for kinetic modeling. The logistic model for cell growth, Luedeking-Piret model for ethanol production and Modified Luedeking-Piret model for substrate consumption were studied. Kinetic parameters were determined by fitting the observed values of the models. The findings indicated that the predicted data with the suggested kinetic model for each medium fitted very well the experimental data. Estimated kinetics were also in good agreement with experimental kinetics. The techno-economic analysis was performed with the unit costs of the components used in the medium and ethanol. Medium-based process economic feasibility proved carob extract-based Medium E and subsequently Medium D as most economical for ethanol production. The present study verified the potential of carob extract-based medium for increased economical production of ethanol. In conclusion, the ethanol production in a biofilm reactor is growth-associated since α (gP/gX) was greater than β (gP/gX.h) and Media D and E increased the economic production of carob extract-based ethanol.
Improved Altitude Control Algorithm for Quadcopter Unmanned Aerial Vehicles
Authors: Xuan-Mung Nguyen , Hong Sung-Kyung
Published: May 2019

Quadcopter unmanned aerial vehicles continue to play important roles in several applications and the improvement of their control performance has been explored in a great number of studies. In this paper, we present an altitude control algorithm for quadcopters that consists of a combination of nonlinear and linear controllers. The smooth transition between the nonlinear and linear modes are guaranteed through controller gains that are obtained based on mathematical analysis. The proposed controller takes advantage and addresses some known shortcomings of the conventional proportional–integral–derivative control method. The algorithm is simple to implement, and we prove its stability through the Lyapunov theory. By prescribing certain flight conditions, we use numerical simulations to compare the control performance of our control method to that of a conventional proportional–derivative–integral approach. Furthermore, we use a DJI-F450 drone equipped with a laser ranging sensor as the experimental quadcopter platform to evaluate the performance of our new controller in real flight conditions. Numerical simulation and experimental results demonstrate the effectiveness of the proposed algorithm.
