Separation of IGCC syngas by using ZIF-8/dimethylacetamide slurry with high CO2 sorption capacity and sorption speed but low sorption heat

An absorption-adsorption hybrid method for separating the integrated gasification combined cycle (IGCC) syngas using ZIF-8/dimethylacetamide (DMAC) slurry was proposed. The viscosity of ZIF-8/DMAC slurries and its sorption performance of pure CO2 were investigated and one optimized slurry with moderate viscosity and high sorption capacity was proposed. Parallel absorption experiments show that the apparent solubility of CO2 in the slurry was doubled compared with that in pure liquid DMAC or propylene carbonate; it even overcomes that in aqueous monoethanolamine solutions at middle to high pressure range. More importantly, the slurry exhibits higher CO2 capture speed compared with conventional absorbents, while its desorption heat is only ∼16 kJ/mol. The equilibrium separation results on H2/CO2 mixtures using ZIF-8/DMAC slurry show that the selectivity of CO2 over H2 ranged from 22 to 119; it increases with decreasing temperature or pressure, increasing initial gas to slurry ratio or CO2 concentration in feed gas. Only 4 theoretical equilibrium stages are required to achieve a sufficient separation of IGCC syngas. Regeneration test shows that the crystal structure of recovered ZIF-8 remains intact after 6 sorption-desorption cycles. This work provides an efficient method for the separation of IGCC syngas at pressure of 2–5 MPa.

Concept Analysis of Social Support of Nursing Students Using a Hybrid Model

The purpose of this study was to analyze the concept of social support of nursing students using a hybrid model and to derive a definition and attributes of social support through theoretical, fieldwork, and final analysis stages. Twenty-nine studies were analyzed in the theoretical stage. Seventeen in-depth interviews were conducted with nursing students in the fieldwork stage. In the final analysis stage, the concept of social support was defined and the attributes were derived by integrating the theoretical and fieldwork stages. The attributes of social support of nursing students identified in the final analysis consisted of two dimensions and eight attributes. The two dimensions were structural and functional support. The eight attributes were social network, educational, emotional, informational, economic, positive evaluation, self-esteem support, and support by providing a role model provision. The structural dimension included the social network support attribute. The functional dimension included the remaining seven attributes. Educational support and support by providing of a role model provision were newly derived attributes that reflected specific characteristics of nursing students. Based on the results of this study, we suggest that researchers should attempt to develop a scale to measure the social support of nursing students.

Educational potential of Russian senior citizens

Introduction. Nowadays, in relation to the marked increase in the proportion of citizens of senior working age in the total Russian population, it is necessary to create the conditions for the development of human and educational potential in order to maintain social activity of senior people for as long as possible and successfully continue their professional activities.The aims of the present research are the following: to understand and promote foreign and Russian practices of education of people of pre-retirement and retirement age; to study readiness of senior citizens for training and further employment.Methodology and research methods. At the theoretical stage of the survey, an analytical review of scientific and regulatory sources was carried out. A questionnaire survey was organised in order to collect empirical data. 418 people (males and females) aged 50 to 72, who have different social statuses, education levels and incomes, took part in the survey.Results and scientific novelty. Comparative theoretical analysis of Russian and foreign solutions to the problems under discussion has shown that in Russia there is a legislative framework for managing the development of educational potential of senior citizens. However, unlike most developed countries, Russia does not have practical experience in the implementation of training of senior citizens. The factors, which have a positive impact on the employment of older generations, are identified: in addition to material interest, they include a high level of qualification, rare skills, and a desire to maintain good health, independence and self-respect. The surveys have demonstrated that many senior people, especially university diploma holders, entrepreneurs and self-employed, quite highly appreciate their professional qualities, abilities, merits and reputation. Senior people would like their experience, wealth of knowledge and skills to be in demand; they believe that they could perform social roles and functions such as a mentor or consultant in the professional sphere, an adviser in the authorities, an independent expert, etc. However, negative stereotypes regarding senior workers in the society – as they tend to have poor health, they are passive, helpless, ineffective, conservative, poorly trained, etc. – become a source of discrimination in the labour market. The interviewees disagreed with the characteristics attributed to them. The greatest objections were judgments that senior people were the brake of innovation (71.6%) and incapable of learning (77.1%). The respondents approved the planned measures to provide them with opportunities for additional education and more than half of respondents demonstrated readiness to receive education in various forms: at universities for people of the third aged, in retraining institutions, in courses of advanced training, etc. At the same time, in Russia, adequate organisational, socio-psychological, pedagogical and other conditions for the education of citizens of this age category have not been created yet.Practical significance. The research findings, the results of surveys and the conclusions drawn could contribute to the justification of new directions of state education policy in order to improve its effectiveness for people of senior generations.

Effectiveness of saponified D2EHPA in Zn(II) selective extraction from concentrated sulphuric solutions

Selective extraction of Zn(II) from industrial leach solutions containing Fe, Ni and Co is still a challenging task. In this paper solvent extraction of Zn(II) with D2EHPA and 5% saponified D2EHPA from sulphuric solutions has been performed. Experimental tests carried out on concentrated solutions allowed to select the operative conditions that allow to obtain both high Zn(II) extraction yield and selectivity. On the basis of the experimental results, a separation process has been proposed for the selective recovery of Zn from a solution containing 60 g/L of Zn. Zn extraction with saponified D2EHPA has been carried out in two different steps. In the first one 2 M D2EHPA has been used for extracting Fe(III) and part of Zn, while in the second one 1 M D2EHPA has been used for recovering the remaining Zn with less than two theoretical stages.

Solvent extraction of uranium and vanadium from carbonate leach solutions of ferruginous siltstone using cetylpyridinium carbonate in kerosene

The leachability of uranium and vanadium ions was conducted from ferruginous siltstone using carbonate ions. The optimum alkaline leaching parameters for dissolving about 92.92% U(VI), and 94.82% V(V) were 70 mg/L Na2CO3, 150 mg/L NaHCO3, 1:3 solid:liquid (S:L) ratio, and 150 rpm stirring rate, for 5 h leaching time at 50 °C. Uranium and vanadium ions were extracted from the carbonate leach liquor using the prepared cetylpyridinium carbonate [(CP)2CO3] in kerosene. The maximum extraction of U(VI) was gained using 0.012 M/L (CP)2CO3 and 5% (w/v) tridecyl alcohol (TDA) in kerosene from the carbonate leach solution assaying 413 mg/L U(VI) at pH 11 and 3:1 aqueous:organic (A:O) phase. Moreover, the maximum extraction of V(V) was achieved using 0.012 M/L (CP)2CO3 and 5% (w/v) TDA in kerosene from the carbonate leach solution containing 336 mg/L V(V) at pH9, and 3:1 A:O phase ratio. Vanadium ions were scrubbed from the uranium-loaded solvent and then it was followed by uranium stripping while vanadium ions were stripped from the vanadium-loaded solvent. McCabe–Thiele diagrams for U(VI) and V(V) extraction and stripping were constructed to determine the theoretical stages of extraction and stripping. Finally, the optimum conditions were applied to gain the sodium diuranate and ammonium vanadate cakes from carbonate leach liquor with the appropriate purities.

Purification of concentrated nickel sulfuric liquors via synergistic solvent extraction of calcium and magnesium using mixtures of D2EHPA and Cyanex 272

A synergistic solvent extraction circuit consisting of D2EHPA and Cyanex 272 was applied to purify a concentrated Ni sulfuric solution ([Ni] = 88 g L−1, [Mg] = 3.1 g L−1, [Ca] = 0.5 g L−1) similar to the MHP industrial liquors that feed the electrowinning step. The temperature was identified as a key parameter to optimize Mg extraction as well as to promote the selective recovery of co-extracted Ni in the extraction stages and make the stripping of Ca feasible using HCl as a stripping agent. Ca was crowded out by Ni from the loaded D2EHPA + Cyanex 272 solution and limited the operating pH range between 2 and 4. Under optimum conditions, 98.0% Ca and 98.4% Mg were simultaneously extracted in two and three theoretical stages by D2EHPA (0.30 M) + Cyanex 272 (0.32 M) mixture (pH 4, A/O ratio = 0.7 and 50 °C). Co-extracted Ni was selectively recovered (99.7%) from the loaded D2EHPA + Cyanex 272 using [H2SO4] = 0.063 M in three stages (O/A ratio = 1 and 50 °C). Ca and Mg can be completely stripped out from the loaded D2EHPA + Cyanex 272 at 50 °C in only 1 ([HCl] = 3 M, O/A ratio = 5) or two theoretical stages ([H2SO4] = 1 M, O/A ratio = 2). The purified liquor containing 80 g L−1 Ni (99.9% purity) can be directed for the electrowinning step to produce Ni cathodes. Extraction and stripping kinetics are rapid (equilibrium reached within 5 min). Thermodynamic analysis was done to support the synergism/antagonism trends observed experimentally.

Sclareol purification using the supercritical fractionation process: A modeling case study

The aim of this study was to model experimental results obtained for the supercritical CO2 fractionation of a liquid mixture containing 24% of sclareol in order to recover a raffinate with increased sclareol content. First, supercritical CO2 fractionation experiments were carried out at pressures (10–12) MPa, and temperatures (313–338) K. Secondly, the modeling of the raffinate and extract compositions for 12 selected compounds including sclareol was performed using the group method. The modeling was carried out at a temperature of 323 K and pressures of (10–11) MPa, and at a temperature of 338 K and a pressure of 12 MPa. The calculation of the raffinate and extract compositions required the adjustment of the number of theoretical stages and of the distribution coefficients for the selected compounds. Experimental raffinate and extract compositions were represented by the model with a relative error of about 15%.

Extraction of Uranium(VI) Ions from Sulfate Medium Using Synthesized o-(1-{(E)-[1-(o-Hydroxyphenyl)ethylidene]-hydrazono}ethyl)phenol

A new Schiff base extractant, o-(1-{(E)-[1-(o-hydroxyphenyl)ethylidene]hydrazono}ethyl)phenol (HPEHEP), was synthesized to separate and preconcentrate U(VI) ions from sulfate solution. Various instrumental techniques such as elemental analysis, FTIR, and 1H NMR were employed for full characterization of the synthetic extractant. Analysis of the traditional log D-log [extractant concentration] and log D-pH dependences shows that the uranium ions were extracted as a complex with the ligand: metal ratio of 2: 1, containing one ionizable hydrogen ion. The uranium extraction and stripping conditions have been experimentally optimized. From the extractant effects, 1.86 × 10−2 M HPEHEP was found to be suitable for the U separation. The thermodynamic study indicates that the extraction of uranium(VI) from sulfate medium is an exothermic process (ΔH = −9.87 kJ mol−1). The construction of extraction and stripping isotherms shows that three theoretical stages will be sufficient for countercurrent treatment. The tolerance limits for several metal ions with the synthesized Schiff base extractant were calculated and gave high tolerance limit. The optimum parameters of solvent extraction were finally applied to sulfate leach liquor.

La ciencia como recurso para el desarrollo turístico sostenible de los Archipiélagos Patagónicos

The article analyses the activation of the object “science” on the coast of southern Chile to create a destination for scientific tourism. A territorial resource is “revealed” through the selection and enhancement of scientific objects. A research centre acts as an articulator of the tourism development project and trans‑ forms “generic” resources to “specific” ones. New heritage milestones are created around cultural geographi‑ cal areas and relevant themes for scientists and local actors. New social links and collective dynamics allow the creation and insertion of an emerging tourist destination in the national and international scenario. Giving value to resources for the creation of a sustainable destination is carried out in 5 theoretical stages; selection, justification, conservation, exposure and valorisation. In practice, it requires the formation of a network of actors to clarify the nature of the destination and the marketing of four possible scientific tourism products: scientific and sports explorations, eco‑volunteering or cultural trips with scientific content. In this manner the Patagonian Archipelagos offers products based on scientific resources enhanced by local actors to create a sustainable destination.

Concept Development of Political Competence for Nurses

The purpose of this study was to define and clarify the concept of political competence for nurses. A hybrid model method was used to investigate the dimensions, attributes, and definitions of the concept. In the theoretical stage of the study, literature on nursing, politics, and other discipline were reviewed. In the fieldwork stage, individual in-depth interviews and focus groups interviews were conducted with politically seasoned experts or activists who had an understanding of the concept of political competence for extensive descriptions in nursing and field of health care. The concept of political competence was represented in four dimensions as political knowledge, political efficacy, political interaction, and political activity. In the political knowledge dimension, there were three attributes, namely, political knowledge, political information and systematic analysis ability. The political efficacy dimension had three attributes of internal political efficacy, external political efficacy, and self-pride of nursing profession. The political interaction dimension had three attributes of organizations and community service, networking, and persuasive power. The political activity dimension had six attributes of political leadership, political expression, assertive behavior, political advocacy, political participation, and policy intervention. This concept development might provide a basic understanding of developing a measurement tool and for constructing a theory promoting nurses' political competence.

Isopropyl Alcohol Purification through Extractive Distillation using Glycerol as an Entrainer: Technical Performances Simulation and Design

Isopropyl alcohol is widely used as industrial chemical intermediates and common solvents in households, pharmaceuticals, food, cosmetics, and medical purposes. The high purity of isopropyl alcohol requires special separation from its impurity i.e. water due to isopropyl alcohol and water form an azeotropic point, which is difficult to separate using a conventional distillation method. The azeotropic point of this mixture is at isopropyl alcohol mole fraction of 0.68 and temperature of 353.4 K. One of the optimum methods to separate an azeotrope point is through the extractive distillation which use a third component as a solvent. Glycerol is one of the solvents which can be used as a potential entrainer in the extractive distillation. Glycerol is produced in the biodiesel production as a by-product. Moreover, glycerol is an eco-friendly chemical. In this work, the simulation of the extractive distillation of isopropyl alcohol/water system with glycerol as an entrainer was simulated using Aspen Plus. The Non-Random Two-Liquid (NRTL) model was used as thermodynamic model in the simulation. The effect of stage number, binary feed stage, entrainer feed stage, and reflux ratio to the purity of isopropyl alcohol, and reboiler-condenser duties were examined to achieve the optimum design for the extractive distillation column with less energy requirements. The simulation results showed that the optimum configurations in the extractive distillation column design are at 25 theoretical stages, binary feed stage (BFS) of 20, entrainer feed stage (EFS) of 2, and reflux ratio (RR) of 0.5 to produce isopropyl alcohol with the purity of 99.27%. The design and sizing of the extractive distillation column were also proposed in this work.

A Novel Hollow-Fiber Membrane Embedded Co-axial Microdevice for Simultaneous Extraction and Stripping

ABSTRACTHow to realize multistage liquid-liquid extraction in a single microdevice is a big challenge in micro-separation processes. No simple solution has been presented until now. In this work, we designed a hollow-fiber membrane-embedded co-axial microdevice with a controllable transmembrane pressure to realize a multistage extraction process successfully. Using the extraction of phenol as a model system, the steady liquid-liquid-liquid three-phase flow of the feed, extractant, and back-extractant was realized in the designed microdevice. By precisely controlling the pressure of the tube side, the extractant was separated from the feed in situ and passed into the shell side to contact with the back-extractant directly. In this way, both of the extraction yield and stripping yield reached 95%. And by introducing a transmembrane pressure with periodic oscillation, five theoretical stages were successfully achieved within 3 min residence time in the single microdevice. This technology may open a new area for microfluidic applications.

Теоретичні засади використання системного підходу до процесу формування соціальної активності молоді в інститутах громадянського суспільства

The multidimensional nature of the notion «system» is conditioned by a wide range of factors applied in philosophical, pedagogical and social studies. The review of scientific and encyclopaedic literature on systemic research confirmed the versatility of approaches to the definition of “system”. The purpose of the article is theoretical analysis of scientific approaches to the concept «system», characterization of system types in the context of pedagogical research. The determined approaches to this category in the scientific theory and practice allow considering the system as an orderly classification of interrelated elements which, interacting with the environment, form a holistic system, constitute a set of interacting elements oriented towards the achievement of a specific goal. It has been defined that a set of components oriented towards the goal determines the basis of the research system and systematic research methods. It has been determined in the article that autonomy in choosing ways of action on the basis of the developed criteria is the characteristic feature of purposeful systems. During the research, the importance of introducing the systematic approach to modern pedagogical science was emphasized, in particular the problem of forming social activity of youth in the institutions of civil society. The systematic approach involves performing a number of tasks: developing system goals; constructing objects as a system; building models of the system; determining system properties; studying the functioning of the system. In the context of our study, it is worth noting that the social, pedagogical, social-pedagogical and innovative systems that justify a number of principles, features and characteristics that are considered relevant during the formation of social activity contribute to the development of the system enabling the development of young people’s social activity. The analysis of the scientific-pedagogical literature made it possible to identify the main characteristics of these systems. According to the results of theoretical analysis, the concept and development stage of the system enabling the formation of young people’s social activity in the institutions of civil society were determined. Keywords: system, systematic approach, pedagogical system, innovative system, social-pedagogical system, youth.

Investigating users’ willingness of acceptance for background music service in intelligent library

PurposeThe purpose of this paper is to study the users’ willingness for acceptance of background music service in university libraries based on intelligent campus and to improve the intelligence level of university libraries and provide a reference for the atmosphere.Design/methodology/approachThe research method of combining theory with practice is applied, and field distribution method and network survey method are used. An algorithm model is established to investigate relevant users, and statistical analysis of the data obtained is made.FindingsThe results show that in the questionnaire survey, girls are more inclined to study in the environment of library than boys; for grade, sophomores and juniors are more inclined to go to library than other grades; through model analysis, the target users are more inclined to choose light music as background music, accounting for 65 percent. Heavy metals and other users have fewer choices, accounting for only 8 percent.Research limitations/implicationsThis questionnaire is mainly filled out in paper form on site, so it only selects some nearby students as the survey objects. However, the condition of university libraries across the country must be different due to regional differences, disciplinary differences and funding differences, so the representative sample may be insufficient. Therefore, in the follow-up research, the scope of the survey should be expanded, especially the geographical scope. It should collect as much data as possible for students of different types and genders, so as to expand the applicable scope and explanatory power of the model.Practical implicationsStarting from the library scene, this research studies the acceptance intention of users of background music service in the library, which provides reference for the improvement of the intellectualization of university libraries and their atmosphere. Although different university libraries have different operation modes and service characteristics, the conclusions of this study have certain practical significance for the library industry because the library industry has many commonalities.Originality/valueAt present, the research on the background music service of University Library based on the smart campus is relatively rare and limited to the theoretical stage. Few people have deeply explored the background music service of the library, and no scholars have quantitatively studied it. In this study, based on the questionnaire and from the perspective of users, the acceptance intention of background music service users is investigated, which provides a reference for the improvement of the intellectualization of university libraries and its atmosphere. It is a research topic of great practical significance.

Research on the Development Method of the Semantic Web Application Based on AllegroGraph

With the continuous development of semantic web technology, semantic web applications are getting more and more attention. However, the research on semantic web applications at home and abroad is still in the theoretical stage, lacking the specific methods of semantic web application development. Moreover, there are few semantic web products for users. In response to this problem, the advantages of AllegroGraph in semantic data storage and query as well as in the semantic web application development are introduced. Then the development framework of the semantic web application based on AllegroGraph and its implementation method are given. Specifically, taking information retrieval as an example, the construction process of the data layer, the logic layer and the presentation layer are described in detail. The experimental results show that the information retrieval method based on semantic, compared with that based on keyword, has a significant improvement in the recall rate and precision rate, which lays a foundation for the application of semantic web products in enterprises to a certain extent.

Indoor Thermal Environment Control System Based on Maximum Work Efficiency

Based on the indoor thermal environment on the influence of the office personnel work efficiency on the basis of experimental research. In this paper, a control method based on maximizing work efficiency is proposed, which aims at maximizing indoor staff’s work efficiency and rest efficiency, and takes Predicted Mean Vote (PMV) as control parameter to control indoor environment, taking into account the requirements of comfort. The operation effect of the control method based on maximum work efficiency is estimated. It is found that compared with the traditional control system based on PMV index, the system not only improves the work efficiency and rest efficiency of indoor personnel, but also is more comfortable. The indoor environment control system based on maximizing work efficiency is still in the theoretical stage. The construction and actual operation effect of the system need to be further studied.

Adaptive support of it solutions (on the example of 1C: Enterprise 8.3 configurations)

The article is devoted to the results of an actual study, the purpose of which was to develop and implement design solutions for adaptively supporting configurations of the “1C: Enterprise 8.3” platform for subsequent practical application in the development of typical configurations for solving applied problems of small and medium-sized enterprises. The relevance of the study is determined by several positions. Firstly, the introduction of information technologies in the most important sectors of the economy helps to increase labor productivity, improve the overall investment climate in Russia, and helps to reduce the dependence of the country’s economy on commodity exports. Secondly, the low degree of realization of the potential of boxed solutions is due to the fact that many enterprises relate to the implementation and subsequent maintenance of such solutions as technical projects, not taking into account their business component. Thirdly, in some cases, when purchasing a replicated solution, it needs to be adapted to business requirements and the new IT infrastructure. Adaptation is carried out at the implementation stage or at the stage of supporting the implemented solution. However, the success of such work depends not only on the implementation and support specialists, but also on the availability of descriptions of specific rules, actions, and work that must be performed. At the same time, a lack of logically structured recommendations on their adaptation after acquisition and implementation is noticeable. The study took place in two stages. At the theoretical and methodological stage, a study of the subject area was carried out. The use of structural and object-oriented analysis and design tools made it possible to analyze the business processes of transferring data from the existing BOSS-Kadrovik automated system (AS) to 1C: ZUP, as well as the process of writing off material balances from account 10 to “1C: Accounting 3.0”, identify problem areas (analysis of IDEF0 functional models) and formulate the image and boundaries of the project (requirements model in the form of a use case diagram – Use Case). Selected adaptive support options were determined in accordance with the support rules recommended by 1C when implementing standard implementation technology. For the “1C: Salary and Enterprise Management 3.1” configuration, it was decided to develop a configuration extension, for adapting the “1C: Accounting 3.0” configuration, the creation of external processing. The design phase of work on the topic of this study involved the development of design solutions for the adaptation of the indicated configurations. At the same time, data models were developed at the logical and physical levels, the requirements for information support in the form of database directories were formulated. In addition, the dynamic component of the solutions being developed was examined, namely, the transitions of some objects from one state to another when fulfilling the selected precedents and the results of the state change. For these purposes, a special type of UML diagram technique was used – activity diagrams. Implementation of design solutions for adaptive configuration support was carried out on the 1C: Enterprise 8.3 platform. Testing the implemented solutions yielded positive results. In addition, the cost of adaptive support was calculated. In the calculation, the time norms for the configuration stage proposed by 1C were taken into account.
