Opis:
The purpose of this study is to investigate the entrepreneurial insight of purchase intention and co-developing behavior of organic food consumption in Thailand during the COVID-19 pandemic. The study is unique because it considers the management of changing lifestyle and eating habits of people occasioned by the increasing global health awareness brought about by the pandemic. The study has adopted the Stimuli-Organism-Response (SOR) paradigm to provide a conceptual model that incorporates corporate image and consumer engagement literature. The research used primary data collected from consumers in major cities across Thailand. The data was collected using a structured questionnaire. The hypotheses of the study were evaluated using Structural Equation Modeling (SEM). The findings of the study indicated that corporate image and corporate social responsibility have a strong influence on consumer trust. Corporate image and corporate social responsibility also have a positive and significant effect on personal values. Consumer trust and personal values were found to influence purchase intention significantly and positively, while purchase intention positively influenced co-developing behavior. Both consumer trust and personal values were found to positively mediate the relationship between corporate image, corporate social responsibility and purchase intention. The study recommended that business management should emphasize and cultivate a strong corporate image and corporate social responsibility image, which would increase customers' trust, their interactions, and interactions with the business, and the resultant purchase intention and co-developing behavior.
Celem tego badania było zbadanie przedsiębiorczego wglądu w intencje zakupowe i współrozwoju zachowań konsumpcji żywności ekologicznej w Tajlandii podczas pandemii COVID-19. Badanie było wyjątkowe, ponieważ uwzględniało zarządzanie zmieniającym się stylem życia i nawykami żywieniowymi ludzi spowodowane rosnącą globalną świadomością zdrowotną wywołaną pandemią. W badaniu przyjęto paradygmat Stimuli-Organism-Response (SOR), aby zapewnić model koncepcyjny, który obejmuje wizerunek firmy i literaturę dotyczącą zaangażowania konsumentów. W badaniu wykorzystano dane pierwotne zebrane od konsumentów w największych miastach Tajlandii. Dane zostały zebrane za pomocą ustrukturyzowanego kwestionariusza. Hipotezy badania zostały ocenione za pomocą modelowania równań strukturalnych (SEM). Wyniki badania wskazują, że wizerunek firmy i społeczna odpowiedzialność biznesu mają silny wpływ na zaufanie konsumentów. Również wizerunek firmy i społeczna odpowiedzialność biznesu mają pozytywny i znaczący wpływ na wartości osobiste. Stwierdzono, że zaufanie konsumentów i wartości osobiste istotnie i pozytywnie wpływają na zamiar zakupu, podczas gdy zamiar zakupu pozytywnie wpływa na zachowania współrozwojowe. Stwierdzono, że zarówno zaufanie konsumentów, jak i wartości osobiste pozytywnie wpływają na związek między wizerunkiem firmy, społeczną odpowiedzialnością biznesu i zamiarem zakupu. W badaniu zalecono, aby kierownictwo biznesowe podkreślało i pielęgnowało silny wizerunek firmy i wizerunek społecznej odpowiedzialności biznesu, co zwiększy zaufanie klientów, ich interakcje i interakcje z firmą, a także wynikający z tego zamiar zakupowy i wspólne zachowanie.

Opis:
The goal of multi-criteria decision making (MCDM) is to select the most appropriate of the alternatives by evaluating many conflicting criteria together. MCDM methods are widely available in the literature and have been used in various energy problems. The key problems studied in electrical power systems in recent years have included voltage instability and voltage collapse. Different flexible alternating current transmission systems (FACTS) equipment has been used for this purpose for decades, increasing voltage stability while enhancing system efficiency, reliability and quality of supply, and offering environmental benefits. Finding the best locations for these devices in terms of voltage stability in actual electrical networks poses a serious problem. Many criteria should be considered when determining the most suitable location for the controller. The aim of this paper is to provide a comparative analysis of MCDM techniques to be used for optimal location of a static VAR compensator (SVC) device in terms of voltage stability. The ideal location can be determined by means of sorting according to priority criteria. The proposed approach was carried out using the Power System Analysis Toolbox (PSAT) in MATLAB in the IEEE 14-bus test system. Using ten different MCDM methods, the most appropriate locations were compared among themselves and a single ranking list was obtained, integrated with the Borda count method, which is a data fusion technique. The application results showed that the methods used are consistent among themselves. It was revealed that the integrated model was an appropriate method that could be used for optimal location selection, providing reliable and satisfactory results to power system planners.

Opis:
This paper presents a novel fault detection algorithm for a three-phase interleaved DC–DC boost converter integrated in a photovoltaic system. Interleaved DC–DC converters have been used widely due to their advantages in terms of efficiency, ripple reductions, modularity and small filter components. The fault detection algorithm depends on the input current waveform as a fault indicator and does not require any additional sensors in the system. To guarantee service continuity, a fault tolerant topology is achieved by connecting a redundant switch to the interleaved converter. The proposed fault detection algorithm is validated under different scenarios by the obtained results.

Opis:
Since 2011, the Syrian Civil War has become an arena of international competition between regional and global powers. As a dominant regional actor, Turkey has important interests in this conflict. However, although great importance is given to civil war factors and power balances at the field level, Turkey’s internal conditions play a role as well as these externalities. Therefore, an analysis of Turkey’s foreign policy towards Syria from a local perspective is needed to reveal some negligible dynamics. In this direction, this study aims to analyse Turkey’s foreign policy towards Syria, taking into account the interaction between Turkey’s external and internal dynamics within the framework of neoclassical realist theory. Within this scope, we ask “how do Turkish external and internal dynamics explain its foreign policy in Syria?” as the leading search question and conduct our analysis using the explanatory case study method. Based on our findings, we provide a broad perspective on the significant impacts of four main internal factors on Turkish foreign policy, from the start of the Civil War to the most recent “Operation Spring Shield” by the Turkish Army and local Syrian armed groups.
Od 2011 roku syryjska wojna domowa stała się areną międzynarodowej rywalizacji pomiędzy regionalnymi i globalnymi mocarstwami. Jako dominujący aktor regionalny, Turcja ma w tym konflikcie ważne interesy. Jednak, mimo że dużą wagę przywiązuje się do czynników wojny domowej oraz równowagi sił na poziomie międzynarodowym, to oprócz tych zewnętrznych uwarunkowań pewną rolę odgrywają również wewnętrzne uwarunkowania Turcji. Dlatego też potrzebna jest analiza polityki zagranicznej Turcji wobec Syrii z perspektywy lokalnej, aby ujawnić pewne pomijalne dynamiki. W tym kierunku, niniejsze opracowanie ma na celu analizę polityki zagranicznej Turcji wobec Syrii, biorąc pod uwagę interakcję pomiędzy zewnętrzną i wewnętrzną dynamiką Turcji w ramach neoklasycznej teorii realistycznej. W tym zakresie zadajemy pytanie „jak turecka dynamika zewnętrzna i wewnętrzna wyjaśniają jej politykę zagraniczną w Syrii?” jako wiodące pytanie poszukiwawcze i przeprowadzamy naszą analizę przy użyciu metody wyjaśniającego studium przypadku. W oparciu o nasze ustalenia przedstawiamy szeroką perspektywę znaczącego wpływu czterech głównych czynników wewnętrznych na turecką politykę zagraniczną, od początku wojny domowej do najnowszej „operacji Wiosenna Tarcza” prowadzonej przez armię turecką i lokalne syryjskie grupy zbrojne.

Opis:
This study investigates the relationship between FDI, economic growth and financial development in the Next 11 countries. An analysis of the results was performed accordingly on the panel data gathered from the Next 11 countries from 1985 to 2019 - using the Pooled Mean Group (PMG) estimation method and the Autoregressive Distributed Lag model approach (ARDL). The results indicate an impact of both economic growth and financial development on the FDI flows to the study of countries during the period between 1985 and 2019 in the long run, while no such proof is affirmed in the short run. This study’s contribution provides a better understanding of the dynamic relationship between FDI, economic growth, and financial development by providing decision-makers to understand the nature of the dynamic association between the study variables. This study provides empirical evidence about the association between inflows of FDI, economic growth and financial development within the context of the Next-11 countries. The previous literature lacks empirical study on the relationship between variables of study for the Next-11 countries.

Purpose: The paper aims to highlight the trends in accounting research that used a literature review as their core research approach. The paper also provides an in-depth review of recent systemised reviews to analyse this trend. Methodology/approach: We analyse recent trends in systemised literature reviews in accounting along with coverage of related methodological considerations in research handbooks. Findings: The tendency to automate literature research is demonstrated. Initiatives to systematise the literature review were consistent with the standardisation of the research procedure necessary to develop specialised software. Identified examples of the application of big data analytics and artificial intelligence methods in the synthesis of various areas of accounting research signal the beginnings of the intelligent automation of literature research. Research limitations/implications: The intelligent automation of accounting research is a dynamic phenomenon that requires further, more in-depth analysis. Originality/value: The paper contributes to the very important and current topic of the digital transformation of accounting research.

Opis:
Heart disease is the leading cause of death in the world according to the World Health Organization (WHO). Researchers are more interested in using machine learning techniques to help medical staff diagnose or detect heart disease early. In this paper, we propose an efficient medical decision support system based on twin support vector machines (Twin-SVM) for heart disease diagnosing with binary target (i.e. presence or absence of disease). Unlike conventional support vector machines (SVM) that finds only one optimal hyperplane for separating the data points of first class from those of second class, which causes inaccurate decision, Twin-SVM finds two non-parallel hyper-planes so that each one is closer to the first class and is as far from the second class as possible. Our experiments are conducted on real heart disease dataset and many evaluation metrics have been considered to evaluate the performance of the proposed method. Furthermore, a comparison between the proposed method and several well-known classifiers as well as the state-of-the-art methods has been performed. The obtained results proved that our proposed method based on Twin-SVM technique gives promising performances better than the state-of-the-art. This improvement can seriously reduce time, materials, and labor in healthcare services while increasing the final decision accuracy.

The purpose of this research is to investigate the factors affecting the Behavioral Intention (BI) to use Massive Open Online Courses (MOOCs) in Thailand. The study adopted the Unified Theory of Acceptance and Use of Technology (UTAUT) Model with an extension to include two variables of Perceived Autonomy (PA) and Absorptive Capacity (AC). The study has also investigated the moderating effects of Culture (CUL) on the relationship between the independent and dependent variables. The study was conducted using primary data collected from 490 respondents, who were university students and intended to use MOOCs. The study used structural equation modelling (SEM) to evaluate the relationship between study variables in AMOS 26. The findings of the study indicated that Perceived Autonomy (PA) was found to have a positive and significant effect on Behavioral intention to use MOOCs (BI); Facilitating Conditions (FCS) has a positive and significant effect on Behavioral intention to use MOOCs (BI). Absorptive capacity (AC) has a positive and significant effect on Behavioral intention to use MOOCs (BI); Social Influence (SI) has a positive and significant effect on Behavioral intention to use MOOCs (BI). However, the results indicated that Performance Expectancy (PE) and Effort Expectancy (EE) have a non-significant effect on BI. Additionally, Perceived Autonomy has a positive and significant effect on Performance Expectancy and Effort Expectancy. The results of interaction between Culture and independent variables (PE, EE, SI, FC, AC, & PA) indicated that CUL does not moderate any relationship with dependent variable (BI). This research is considered very critical during the period of COVID-19 pandemics, where most learning is being conducted online. Therefore, the policymakers in the education sector in Thailand, and the heads and management of institutions of higher learning could benefit from the findings of this research.
Celem tego badania jest zbadanie czynników wpływających na intencję behawioralną (BI) do korzystania z Massive Open Online Courses (MOOC) w Tajlandii. W badaniu przyjęto Model Zunifikowanej Teorii Akceptacji i Wykorzystania Technologii (UTAUT) z rozszerzeniem o dwie zmienne: Postrzeganą Autonomię (PA) i Zdolności Absorpcyjne (AC). W badaniu zbadano również moderujący wpływ kultury (CUL) na związek między zmiennymi niezależnymi i zależnymi. Badanie zostało przeprowadzone na podstawie danych pierwotnych zebranych od 490 respondentów, którzy byli studentami uczelni i zamierzali korzystać z MOOC. W badaniu wykorzystano modelowanie równań strukturalnych (SEM) do oceny związku między badanymi zmiennymi w AMOS 26. Wyniki badania wykazały, że postrzegana autonomia (PA) ma pozytywny i istotny wpływ na behawioralny zamiar stosowania MOOC (BI). ; Warunki ułatwiające (FCS) mają pozytywny i znaczący wpływ na behawioralny zamiar korzystania z MOOC (BI). Zdolność absorpcyjna (AC) ma pozytywny i znaczący wpływ na behawioralny zamiar korzystania z MOOC (BI); Wpływ społeczny (SI) ma pozytywny i znaczący wpływ na behawioralny zamiar korzystania z MOOC (BI). Jednak wyniki wskazują, że oczekiwana wydajność (PE) i oczekiwana nakład pracy (EE) mają nieistotny wpływ na BI. Ponadto postrzegana autonomia ma pozytywny i znaczący wpływ na oczekiwaną wydajność i oczekiwany wysiłek. Wyniki interakcji między Kulturą a zmiennymi niezależnymi (PE, EE, SI, FC, AC i PA) wskazują, że CUL nie moderuje żadnego związku ze zmienną zależną (BI). Badanie to jest uważane za bardzo krytyczne w okresie pandemii COVID-19, kiedy większość nauki odbywa się online. Dlatego decydenci w sektorze edukacji w Tajlandii oraz dyrektorzy i kierownictwo instytucji szkolnictwa wyższego mogą skorzystać z wyników tych badań.

This study contributes to the existing literature by estimate Okun’s law for Arab economies during the period 1960–2017. The results of this study indicate that Okun’s coefficient is valid for the case of Arab countries in the different version, when unemployment rates reach the threshold and are between 6.35 and 7.933, in which the impact of the GDP on unemployment rates is negative and significant, with a significant level of 1 per cent. As for outside the threshold, i.e. less than 6.35 and more significant than 7.933, this effect is negative, but it is not significant. Moreover, the decision-makers in Arab countries seek to raise economic growth rates to address unemployment. This investigation provides original empirical evidence on the association between unemployment and economic growth within Arab countries. The current international literature lacks empirical evidence on the relationship between variables of this study for Arab countries as a whole.

Opis:
Groundwater quality determination and age estimation in a desert landscape of El Golea province situated in the south of Algeria has been investigated in the present research paper. For this regard, 57 water samples were collected from an aquifer composed of two superimposed systems; phreatic and deep continental intercalary (CI) aquifers which are a part of the Northern Sahara Aquifer System (NWSAS). Samples were analyzed to assess the age and water quality using descriptive, multivariate statistics (PCA and HCA) and stable isotopes. It is revealed that more than 71% of the IC points are characterized by a water type (Ca2+, Mg2+) (HCO3 – )2 and more than 83% of the TC samples are defined by a water type (Ca2+, Na+) (HCO3 – , SO4 2 – ) and very high salt ions contents due to the influence of surface water, evaporate leaching and irrigation water return. The isotopic composition of samples of phreatic and CI aquifers shows a clear difference between the two qualities of water. The phreatic aquifer is characterized by the δ18O range from –4.68 to –6.1, whereas δ2H from –47.25 to –59.48 and CI with values of the δ18O range from –5.96 to –7.6, and δ2H range between –53.7 and –65.78 isotopic signature. The unconfined aquifer above IC forms a special case of a mixture of ancient water from deep horizons and recent water strongly enriched from shallow horizon lands.

Opis:
Depending on a model for organizational context within work groups and a job perspective for the socially responsible behaviors, we have developed and examined a model for small and medium enterprises' success within the work place that explains some reasons leading to small and medium institutions' success. The sample included 217 workers in small and medium companies in Iraq. It was found that the intellectual capital integration and intentional junior accountants' turnover were related to small and medium companies' success within the work place for companies' members, in addition, there was a direct relationship between accountants' turnover and intellectual capital integration and small and medium companies' success and there also was an indirect relationship mediated by the financial knowledge management system within work groups.
W zależności od kontekstu modelu organizacyjnego w grupach roboczych i perspektywy pracy dla zachowań odpowiedzialnych społecznie, opracowano i zbadano model sukcesu małych i średnich przedsiębiorstw, który wyjaśnia wybrane przesłanki prowadzące do sukcesu tych firm. Próba obejmowała 217 pracowników w małych i średnich przedsiębiorstwach w Iraku. Stwierdzono, że integracja kapitału intelektualnego i celowa rotacja młodszego personelu finansowego były związane z sukcesem małych i średnich przedsiębiorstw, ponadto istniał bezpośredni związek między rotacją personelu finansowego a integracją kapitału intelektualnego i sukcesem małych i średnich firm, a także pośredni związek z systemem zarządzania wiedzą przez system zarządzania wiedzą finansową w ramach grup roboczych.

Opis:
In this work, nickel adsorption onto low Jordanian zeolite dose is being investigated. Natural zeolite doses were stirred continuously with nickel solutions in batch reactors at 180 RPM for 24 hours, where the temperature was set to 20°C. The pH was initially 4.5 and reached 5.2 at equilibrium. The removal efficiency of nickel reaches maximum value when the initial nickel concentration is around 1 ppm and then tends to decrease when the initial nickel concentration increases above 1 ppm. The optimal nickel removal reaches 65% when the initial nickel concentration is 1 ppm and the zeolite dose is 26 mg∙dm–3. This study investigates the behaviour of nickel removal and modelling isotherms below and above this critical peak point. At this level of zeolite dose, the adsorption does not follow either Freundlich or Langmuir isotherms, but rather, it follows Freundlich for the data plot just below the peak point with the highest coefficient of determination (R2) equals (0.98) when the zeolite dose is (26 mg∙dm–3), whereas it follows Langmuir for the data plot just above the peak point with the highest coefficient of determination (R2) equals (0.99) when the zeolite dose is (10 mg∙dm–3). These findings clarify the theory behind each isotherm and can be used to find new information for efficient treatment techniques.

Opis:
This analysis aimed to investigate the factors influencing the behavioural intention to use Massive Open Online Courses (MOOCs) in Thailand and Pakistan. The study was geared towards exploring the MOOCs, a relatively new technology platform allowing the spread of education and learning in various areas and fields and surpassing traditional online courses. The study adopted the UTAUT model with additional two variables of perceived autonomy and absorptive capacity. A quantitative method was applied using primary data collected from a sample of 490 and 513 respondents from Thailand and Pakistan, respectively. The sample size was composed of students in institutions of higher learning who were aware of MOOCs or intended to use them in their studies. The analysis was conducted using the Confirmatory Factor Analysis (CFA) and multi-group structural equation modelling (SEM). The study found that four variables (social influence, absorptive capacity, facilitating conditions and perceived autonomy) significantly influence the student intention to use MOOCs in Thailand and Pakistan. However, two variables (performance expectancy and effort expectancy) did not influence the student intention to use MOOCs in Thailand and Pakistan. The results indicated that the findings between the two countries were invariant. This study extended the model by Venkatesh et al. (2003), including two additional variables, the perceived autonomy and absorptive capacity. The study indicated various aspects related to the response of students using MOOCs. This study is especially beneficial during the COVID-19 pandemic for determining factors that officials of higher institutions of learning should consider when implementing MOOCs and associated online learning programs to deliver quality education to students.

Opis:
Vibration analysis for conditional preventive maintenance is an essential tool for the industry. The vibration signals sensored, collected and analyzed can provide information about the state of an induction motor. Appropriate processing of these vibratory signals leads to define a normal or abnormal state of the whole rotating machinery, or in particular, one of its components. The main objective of this paper is to propose a method for automatic monitoring of bearing components condition of an induction motor. The proposed method is based on two approaches with one based on signal processing using the Hilbert spectral envelope and the other approach uses machine learning based on random forests. The Hilbert spectral envelope allows the extraction of frequency characteristics that are considered as new features entering the classifier. The frequencies chosen as features are determined from a proportional variation of their amplitudes with the variation of the load torque and the fault diameter. Furthermore, a random forest-based classifier can validate the effectiveness of extracted frequency characteristics as novel features to deal with bearing fault detection while automatically locating the faulty component with a classification rate of 99.94%. The results obtained with the proposed method have been validated experimentally using a test rig.

Opis:
This study reports an investigation of the effect of different cellulose materials and yarn feeding patterns on thermo-physiological comfort, sensorial comfort, serviceability/pilling and ultraviolet properties. An interlock structure with a combination of hydrophilic and hydrophobic material was developed in such a way that each material was prominent in consecutive wales or courses. The yarn feed pattern in interlock fabric overcomes the limitation of plaited single jersey fabrics. Cellulose – based hydrophilic natural and regenerated fibres were used i.e cotton, model and viscose rayon, as well as hydrophobic synthetic fibre i.e. polyester for manufacturing fabric samples. By comparing the results, it became clear that wale-wise alternate yarns provide better overall moisture management properties than course-wise. Similarly, for fabric handle and pilling properties, wale-wise alternate yarn provides better properties. Interlock fabrics with the TransDRY® Technology effect are liable for use in protective textiles, medical textiles and in other functional textiles/children’s clothing.
W pracy badano wpływ różnych materiałów celulozowych i schematów podawania przędzy na komfort termofizjologiczny, komfort sensoryczny, użyteczność/mechacenie i odporność na działanie promieniowania UV. Opracowano strukturę blokującą z połączeniem materiału hydrofilowego i hydrofobowego w taki sposób, aby każdy materiał był widoczny w kolejnych rządkach i kolumienkach. Do produkcji próbek dzianin wykorzystano hydrofilowe włókna naturalne i włókna regenerowane na bazie celulozy, tj. bawełnę i jedwab wiskozowy, a także hydrofobowe włókno syntetyczne, czyli poliester. Po porównaniu wyników stwierdzono, że alternatywne przędze zapewniają lepsze właściwości zarządzania wilgocią. Podobne wnioski zostały wyciągnięte, jeśli chodzi o chwyt tkaniny i mechacenie się. Stwierdzono, że dzianiny interlokowe z wykorzystaniem technologii TransDRY® mogą być z powodzeniem stosowane w tekstyliach ochronnych, medycznych i innych tekstyliach funkcjonalnych oraz odzieży dziecięcej.

In the present investigation, heat transfer analysis of peristaltic flow in the presence of heat generation against high values of the Reynolds number using a numerical technique is presented. The Finite Element Method with the assistance of Galerkin’s variational method has been used on the governing Navier-Stokes equation in the stream-vorticity form. The graphs of computed longitudinal velocity, temperature distribution and pressure rise per wavelength are plotted against different values of an emerging parameter using a stream function and vorticity. The presented results are valid beyond the restrictions of long wavelength and low Reynolds number limits. Moreover, large values of the Reynolds number increases pressure rise per wavelength.

Opis:
The aim of this work was to investigate the properties of upholstery fabric produced from recycled hard waste of coloured fabric clippings. Mélange yarns were formed with the combination of red, green, black and yellow in different ratios. Five yarn samples of 5 Nec linear density were produced from each blend ratio using the rotor spinning technique. These yarns were used to develop fabric samples in a satin weave. These yarn and fabric samples were investigated for different quality parameters, especially the abrasion resistance, pilling resistance, absorbency and light fastness of the fabrics as per standard test methods. The abrasion test is important for the durability and longer-lasting performance of upholstery fabric. From the analysis of test results, it is concluded that all the serviceability properties are in a good range, and these fabrics can be used for waiting room area upholstery fabric.
Celem pracy było zbadanie właściwości tkanin obiciowych wytworzonych z recyklingu odpadów kolorowych ścinków tkanin. Przędze melanżowe powstały z połączenia czerwonego, zielonego, czarnego i żółtego koloru w różnych proporcjach. Wytworzono pięć próbek przędzy z każdego stosunku mieszanki przy użyciu techniki przędzenia rotorowego. Przędze zostały wykorzystane do opracowania próbek tkanin. Następnie próbki przędzy i tkanin zbadano pod kątem różnych parametrów jakościowych, w szczególności odporności na ścieranie, odporności na pilling, chłonności i odporności na światło tkanin zgodnie ze standardowymi metodami badawczymi. Test ścieralności jest ważny z punktu widzenia trwałości tkaniny obiciowej. Z analizy wyników badań wynikało, że wszystkie właściwości użytkowe mieszczą się w dobrym zakresie, a tkaniny te mogą być stosowane jako tkaniny obiciowe.

Opis:
The study evaluated the adsorption potential of white cedar sawdust (WCS) for dye removal. WCS was chosen from five preferred, abundant waste biomasses from Pakistan. Various parameters such as contact time, adsorbent dose, dye concentration, pH, and particle size were optimized for methylene blue (MB) dye adsorption. The adsorbent was characterized by FTIR, SEM, EDX and BET analyses. The surface area of the adsorbent was 1.43 m2·g-1 and pore volume was 0.000687 cm3·g-1. The adsorption data best fitted the isotherm models of Langmuir, Temkin, Dubinin–Radushkevich, and Freundlich. The maximum experimental adsorption capacity obtained was 55.15 mg·g-1, which was in close agreement to the calculated adsorption capacity. Fitness of the pseudo-second order kinetics suggested chemisorption as the rate-limiting step. Thermodynamic study for adsorption was carried out to evaluate the Gibbs free energy (ΔG°), enthalpy (ΔH°) and entropy (ΔS°). The negative values ΔG° at the examined temperature range confirmed the spontaneous adsorption of MB onto WCS.

Opis:
The objective of this research work was to estimate the effect of thermal cycling on the tensile behavior of CARALL composites. Fiber metal laminates (FMLs), based on 2D woven carbon fabric and 2024-T3 Alclad aluminum alloy sheet were manufactured by pressure molding technique followed by hand layup method. Before fabrication, aluminum sheets were anodized with phosphoric acid to produce a micro porous alumina layer on surface. This microporous layer is beneficial to produce a strong bond between the metal and fiber surfaces in FMLs. The effect of thermal cycling (-65 to +70ºC) on the tensile behavior of Cf/Al based FML was studied. Tensile strength was increased after 10 thermal cycles, but it was decreased slightly to some extent after 30 and 50 thermal cycles. Tensile modulus also show similar behavior as that of tensile strength.

Opis:
Cr(VI) adsorption was studied for abundantly available low-cost lignocellulosic adsorbents in Pakistan namely, tobacco stalks (TS), white cedar stem (WCS) and eucalyptus bark (EB). Several process variables like contact time, adsorbent dose, pH, metal concentration, particle size and temperature were optimized in batch mode. EB showed high Cr(VI) adsorption of 63.66% followed by WCS 62% and TS 57% at pH 2, which is higher than most of the reported literature. Langmuir isotherm (R2  = 0.999) was well fitted into the equilibrium Cr(VI) data of EB, suggesting homogeneous active sites and monolayer coverage of Cr(VI) onto the EB surface. Freundlich (R2  = 0.9982) isotherm was better fitted to the equilibrium data of TS and WCS, revealing the adsorption sites with heterogeneous energy distribution and multilayer Cr(VI) adsorption. Moreover, the Cr(VI) adsorption of studied adsorbents followed the pseudo-second order kinetic model. Thermodynamic properties were investigated in two temperature ranges, i.e., T1  (303–313 K) and T2  (313–323 K). TS and EB showed the exothermic at T1 and endothermic reactions at T2 with entropy controlled adsorption at the solid-liquid interface, and WCS exhibited an opposite thermal trend with decreasing disorderness at solid-liquid interface as temperature rises. Gibbs free energy (ΔG>0) confirmed the non-spontaneous adsorption process for all studied adsorbents.

Opis:
The influence of basalt fabric on the tensile mechanical properties and the impact resistance of green epoxy resin was investigated. Composites with parallel arrangement of insert yarns had better properties than in the case of their perpendicular arrangement. The properties were also influenced by the number of layers of the fabric. The tensile strength and impact resistance of the composites were better than the commercially available side mirror covers due to the superior properties of the basalt fiber.
Zbadano wpływ tkaniny bazaltowej na właściwości mechaniczne przy rozciąganiu i odporność na uderzenie „zielonej” żywicy epoksydowej. Kompozyty o równoległym ułożeniu przędzy charakteryzowały się lepszymi właściwościami niż te o prostopadłym ułożeniu. Na właściwości miała również wpływ liczba warstw tkaniny. Wytrzymałość na rozciąganie i odporność na uderzenie kompozytów były lepsze niż dostępnych na rynku osłon lusterek bocznych ze względu na dobre właściwości włókna bazaltowego.

Opis:
A series of Mn-doped CeO2-CuO catalyst (CeO2-MnOx-CuO) (Ce/Mn molar ratio of 0.5, 1.0 2.0 and 3.0) were prepared using co-precipitation method for the selective oxidation of CO in automobile engine exhaust. The content of copper was 5.0 wt. % in each sample. Catalysts were installed on the automobile engine exhaust and CO amount was recorded with help of CO sensor, with and without the catalyst. The catalytic converter efficiency was estimated for each catalyst through efficiency formula. It was observed that Ce/Mn catalyst with a molar ratio of 2.0 shows the maximum efficiency (88.35%). Stability of conversion process was analyzed by plotting the CO amount with respect to time. The catalyst with Ce/Mn molar ratio of 2.0 performed the most streamline conversion process with least deviations.

Opis:
The presence of organics materials in phosphate ores generates foam during the manufacture of phosphoric acid, thus affecting the production performance and the quality of the products. Today, in the phosphate industry defoamers are used to reduce the negative impact of foam phosphoric production. In the present work, we focused on root cause evaluation for foam generation during the phosphoric acid production process, we evaluated the effect of phosphate rock quality in terms of organic carbon (OC) and carbonate content, on foam generation using a laboratory protocol for foaming ability evaluation. The results show that there is a relationship between the volume of the foam generated and the values of those impurities, while the volume of foam generated is higher when the concentration of OC and Carbonate is high. In our work, we confirm that the foaming ability of the phosphate rock can be avoided if the concentration of organic carbon less than 0.1% and less than 3% for carbonate.

Opis:
Mineral processing applications increasingly use recycled water to preserve freshwater natural resources and comply with environmental regulations. However, accumulating anions, cations, and reagents in the process water may affect plant flotation performance and production continuity. Therefore, many cost actions may be needed to mitigate the recycled water effects. Typically, the process water properties and their effects on flotation performance are unknown for a greenfield project. Often, the result is an over-scaling up of the process plant with an additional financial cost. The experimental methodology in the paper focuses on creating water for testing that is closer to the actual process water during the comminution and flotation process for any greenfield project. The scope of the study consists of creating possible process water, conducting flotation experiments, and simulation. In order to validate the dissolution loop method, refractory gold flotation plant conditions were selected in our Finland laboratory. The simulation results of dissolution loop flotation kinetics were compared with the actual plant mass balance. According to the comparative results, the process water created by the dissolution loop method has the same physical and chemical properties as the actual process water at the site except for SO4 -concentration. Moreover, comparing the simulation results of the experimental data and plant mass balance studies shows that the gold grade and recovery results in the simulation were lower than the actual plant mass balance.

Opis:
The present study was aimed to identify the indigenous fungal strains which could possibly be applied to the bioremediation of heavy metal-contaminated soil. The contaminated soil samples of Korangi Industrial Estate Karachi were found to have total concentration of Cu 1.044 mgL1 , and Pb 0.631 mgL–1. A total of eight indigenous strains of the fungus were isolated and screened for bioremediation capacity from heavy metals-contaminated soil. For the bioremediation of Lead (Pb) these same indigenous eight fungal strains were used for biological remediation. All the fungal isolated with enhanced bioremediation capability were through phenotypic and genotypical characterization. The topology of the phylograms established that the fungal isolates used in this study were allocated to: K1 (Penicillium notatum), K2 (Aspergillus parasiticus), K3 (Aspergillus fumigatus), K4 (Aspergillus flavus), K5 (Aspergillus terries), K6 (Fusarium solani), K7 (Penicillium chrysogenum), K8 (Aspergillus niger), K9 (Penicillium piceum) and K10 (Penicillium restrictum). Thus, K8 fungal isolate was found to be more efficient with maximum bioremediation capacity, for copper and lead removal efficiency, and selected for FTIR and SEM to find out the uptake of Cu and Pb which of the functional groups are involved, and further to detect the effects of bioleaching of both heavy metals on to the surface of K8 fungus biomass. The current study indicates that indigenous fungal isolates could be used with high potency to remediate or clean up the heavy metals-contaminated soil either by the technique of in situ or ex-situ bioremediation.

Opis:
Satellite-based positioning, which started being developed in the mid-1960s for military purposes, is now used in almost every area. For the studies single and/or double frequency receivers are used. The cost of a receiver and antenna couple that have capable of high coordinate accuracies ranges from $3000 to $15000. With the production of Original Equipment Manufacturer (OEM) receivers, the cost of satellite-based location determination decreases to approximately one in 10 for the civilian user compared to the operations performed with geodetic receivers and antennas. However, although these receivers collect data in multi-Global Navigation Satellite System (GNSS) and frequencies, the accuracy of the coordinate values estimated is not as high as geodetic receivers and antennas. Therefore, it is necessary to carry out an accuracy study to obtain information about which studies can be used in. In this study, measurements were made at the UZEL point located on the roof of the Yıldız Technical University Geomatics Engineering Department by using the ZED-F9P-02B OEM multi GNSS receiver and ANN-MB L1/L2 multi-band GNSS patch antenna. The performance of the test results has been examined by comparing the results from CSRS(Canadian Spatial Reference System)-PPP with the coordinates of the UZEL point. As a result of the comparison, the difference between the coordinate determined with collected 3.5 hr data and the coordinates of the UZEL point has been determined as – 1.4 cm, 2.8 cm, and 9.3 cm in the East, North, and Height directions, respectively.
