Estimation of the displacement of soil nailing vertical face structures intended for building undergrounds

ABSTRACT This study proposes a methodology for estimating horizontal displacements in vertical face soil-nailing structures in urban areas, analyzing 20 projects in São Paulo, Brazil. To minimize displacements, post-grouting sectorized injections through polyethylene tubes was used, a methodology routinely adopted in Brazil which gives the soil mass a significant increase in strength and stiffness.To study the effect of the sectorized injections on soil treatment, a three-dimensional computational model using Plaxis 3D software and calibrated through back-analysis according to the displacements of the structures. Additionally, 11 models were tested with variations in nail length, mesh configuration, and geotechnical parameters, considering injection effects. The study provides design and execution guidelines to optimize this technique. Equations derived from the study predict horizontal displacements, which will be used to assess the technical feasibility of the projects in advance and, when they are being executed, to provide performance control within a more precise and realistic margin.

Assessing Direct Oral Anti-Coagulant And Therapeutic Low Molecular Weight Heparin Prescriptions At A University Teaching Hospital

Abstract Background A 2017-2018 survey identified anti-thrombotics as the most commonly implicated agents in reported medication incidents across Irish acute hospitals [State Claims Agency, 2020, Medication Incidents Report (2017-2018)]. Of the top 10 anti-thrombotics reported, 2 were Low Molecular Weight Heparins (LMWHs) and 3 were Direct Oral Anti-Coagulants (DOACs). 3 years after the survey results were published, we audited our hospital's compliance with the Health Service Executive's guidelines for prescribing DOACs and LMWHs. Methods Over 3 consecutive weeks, data was collected by doctors and clinical pharmacists across 6 wards and the intensive and coronary care units. In-patients on a DOAC or therapeutic LMWH were chosen for kardex and laboratory result review. Results 83 patients were included. The average age was 79 years. 81%(n=67) were on a DOAC. 91% were being treated for non-valvular atrial fibrillation (NVAF), 3% for pulmonary embolism (PE), 3% for deep vein thrombosis and 3% had no indication documented. 33%(n=22) had indications for dose reduction but only 77%(n=17) of them were prescribed the appropriate reduced dose. 3%(n=2) had no dose reduction indications but were inappropriately prescribed a reduced dose. 3%(n=2) were on dialysis, 1%(n=1) had their creatinine clearance persistently below 15ml/min and 1%(n=1) inappropriately received once daily dosing of apixaban for 3 days. 19%(n=16) of all participants were on therapeutic LMWH. Treatment indications included acute coronary syndrome in 63%, suspected PE in 19%, newly diagnosed NVAF in 6% and bridging anti-coagulation while a DOAC is temporarily held in 13%. 6%(n=1) were inappropriately prescribed an under-dose. Conclusion Overall, there was an error rate of 16%(n=11) in DOAC prescriptions and 6%(n=1) in LMWH prescriptions. To address this, we propose an educational intervention for prescribers and the introduction of e-prescriptions with built-in alerts for errors. We plan to re-audit once these recommendations are implemented.

2320 DNAR: all or nothing: impact of education sessions Re-audit

Abstract Introduction Do Not Attempt Resuscitation (DNAR) orders are implemented to obviate inappropriate Cardio-Pulmonary Resuscitation (CPR) in patients with low chances of survival post-CPR. However, ambiguity regarding ceilings of care for patients with a DNAR order can arise. This re-audit aimed to review DNAR and ceilings of care documentation according to national Irish Health Service Executive (HSE) guidelines after education sessions in a Model 3 Hospital. Methods A point-prevalence chart review of thirty-one adult medical inpatients with a DNAR order was conducted after two education sessions were held for Non-Consultant Hospital Doctors (NCHDs) and Consultants. Results Of all thirty-one charts, 35% documented DNAR status in the medical notes, with 32% documenting the reasoning for DNAR status, both unchanged from the first audit cycle. There was an increase in documentation of patient discussion (61% versus 45%) and reasons if this was excluded (66% versus 41%). There was no change in documentation of patient relatives’ discussion (48%) but there was an increase in the reasons if this was excluded (25% versus 18%). There was an overall increase in ceilings of care documentation for ICU admission (three-fold increase), intubation (two-fold increase), inotropic support, and comfort measures, but rates of documentation were still less than 15%. Discussion This audit elucidates the efficacy of education sessions in improving DNAR documentation adherence. Recent studies have highlighted uncertainty among NCHDs regarding treatment escalation in acutely unwell patients in the absence of adequately filled DNAR orders and clear documentation of ceilings of care. We posit the introduction of a Ceilings of Care document, akin to the United Kingdom’s Medical Advance Plan. Conclusion Accurate recording of DNAR status and ceilings of care is essential for quality care and treatment escalation. While simple education strategies have proven beneficial in enhancing compliance, additional efforts are needed to enhance ceilings of care documentation.

Exploring health professionals' knowledge, practices and attitudes regarding gestational diabetes: A cross-sectional Irish national survey.

Gestational diabetes confers short- and long-term risk of mother and offspring health complications. Healthcare professionals such as endocrinologists, diabetes nurses, dietitians, midwives and general practitioners provide gestational diabetes care. We sought to explore healthcare professionals' perspectives on gestational diabetes care during pregnancy and postpartum. Healthcare professionals in the Republic of Ireland, whose role included gestational diabetes care were invited to complete an online 20-item survey between June and September 2022. Social media, professional organisations and personal networks were used for recruitment. Questions included guideline use, postpartum diabetes screening and advice practices. Analyses were performed using SPSS statistical software and free text was coded using NVivo. Seventeen healthcare professions across primary and secondary care settings participated (n = 127). No differences were noted between groups (medical, nursing/midwifery, allied health/other); therefore, findings were reported as a single group. Healthcare professionals reported using multiple different guidelines to support gestational diabetes management (n = 14). The most cited were 'Health Service Executive guidelines' (24.5%), 'local guidelines' (13.2%) and National Institute for Clinical Excellence guidelines (11.3%); 12.3% cited uncertainty, and 27.5% reported not to follow any named guidelines. For postpartum follow-up, 39% felt clear guidelines were available to support practice, 37% felt appropriate systems were in place and 29% reported effective communication between primary and secondary care services. Qualitative findings emphasised a desire for improved communication between systems, participants and providers, clear interdisciplinary guidelines, and adequate resourcing for gestational diabetes management and postpartum diabetes prevention, including comprehensive support and follow-up. System-level challenges and ineffective communication across settings are barriers to optimum postpartum care. Nationally agreed guidelines for best practice gestational diabetes management including postpartum diabetes prevention are needed.

Microplastics: A One Health priority agenda

Interdisciplinary approaches are increasingly recognized as crucial for strengthening and integrating health systems. The implementation within One Health framework needs more guidelines for successful execution. Microplastics have become a growing environmental concern, as they are collectively found in all environmental sectors. Microplastics pose risks to crops, plants, animals, wildlife and human due to the persistence and bio–accumulative properties. Microplastics are directly and indirectly associated with climate change, not only threatening food security but also leading to the novel distribution of species that may transmit new pathogens. This article focused on the ubiquitous presence of microplastics in One Health, highlighting the necessity for further research and implementation efforts.

Pathology of the Implementation System of Iran’s Social Welfare Policies

Introduction: In the implementation of public policy, there are many factors and obstacles, the identification of which will lead to the efficient way of implementing the policies. Method: The present research was conducted with the aim of identifying and prioritizing the obstacles to the implementation of Iran's social welfare policies. The research is of a meta-composite type, in the qualitative part, semi-structured interviews were used so as to collect the data with open coding, and finally the obstacles to the implementation of social welfare policies were identified. In the quantitative part, using the review of related literature and research studies, six fundamental research studies in the field of policymaking were selected according to the citations and the items affecting the implementation of policies having been extracted from other studies in the form of commonalities. Then, the 10 experts cooperated, and the three-step Delphi method was used. Findings: Based on Friedman's test, ten priorities were identified, which are as follows: existence of opposing and supporting parties, technical difficulties, lack of use of new technologies, legitimacy of the country's political and governance system, lack of attention to the intellectual and political maturity of the target group, political factors, political conflicts, the welfare state of the target group, the lack of appropriate executive instructions, the lack of alignment of programs, and the lack of optimal allocation of the country's budget. Discussion: It was found that the influential factors are in the hands of the government and the role of the executives in the implementation of social welfare policies is weaker. Therefore, it is suggested that the government should pay more attention to the use of pro and opposition parties, the legitimacy of the ruling political system, and executive guidelines.

Nanoparticles assisted polymer flooding: Comprehensive assessment and empirical correlation

Conventional Polymer flooding is considered the most promising chemical-enhanced oil recovery by reducing water mobility, and hence increasing the sweep efficiency. However, there are certain drawbacks associated with polymer flooding as the degradation of its molecular structure in severe reservoir environments. Recently, it is experimentally adopted that attachment of nanoparticles (NPs) toward polymer macromolecule may ameliorate the flooding performance and hence increase the oil recovery further than conventional polymer flooding. The potential of NPs assisted polymer flooding has been extensively studied in porous media through core flooding. The target of this work is to statistically scrutinize the previous core flooding experiments and investigate the parameters that affect the incremental oil recovery by NPs assisted polymer flooding. To accomplish this target, a robust investigation of the outcome of over 350 core-flood tests from the literature was gathered to investigate the impacts of rock-oil properties, flooding conditions, polymer, and NPs characteristics on incremental oil recovery. Additionally, Fractional factorial design (FFD) was used to analyze core flood results and screen the effects of reservoir rock, fluid, polymer, and NPs properties on the performance of assisted polymer flooding. Furthermore, an empirical model was built using an Artificial neural network (ANN) to predict the incremental oil recovery for polymeric nanofluid. The results of the investigation indicated that NPs assisted polymer flooding with optimum concentration of both polymer and NPs may result in an incremental recovery of 18% of oil-in-place. Furthermore, the results of FFD revealed that NPs concentration, polymer concentration, and rock permeability are the most significant parameters of oil recovery. The results outcome showed that there is an optimal concentration of both polymer and NPs assisted polymer. In addition, the results revealed that core-flooded viscous oil needs a highly permeable rock to guarantee successful flooding. The coefficient of determination (R2) between the real and calculated incremental oil from the ANN model was established to be 0.953 and 0.952 with an error of 5.6 and 8.7% respectively for the training and testing approaches. Such statistical investigations and ANN approaches afford new insights and guidelines for preliminary assessment, designing, and execution of Nanohybrid polymer upcoming projects on a field scale.

State aid for airlines in the EU: policy changes during the COVID-19 pandemic

The paper analyses the developments in the EU state aid policy as a result of the COVID-19 pandemic breakout. The general framework for state aid in the EU was presented. Based on a case study analysis of selected airlines that benefited from state aid following the COVID-19 crisis, changes in the European Commission approach were identified. In general, investigation of arrangements between the state aid cases is a complex (and thus often lengthy) process. The outbreak of the COVID-19 pandemic was a challenge for EU member states and the European Commission as well due to the unexpected, turbulent, and very profound nature of the crisis. It made it necessary to look for new or revised policies for state aid to respond quickly and keep airlines afloat in times when the flow of revenue was practically stopped. One of the key issues that needed to be addressed was inflexibility and lengthiness of state aid approval processes. To this end, additional guidelines were introduced to make the state aid policy of the EU more flexible. This way member states could respond to the ongoing developments in a more targeted and objective-oriented approach, which possibly made state aid more efficient. It should be stressed that it could have been achieved without changes to pre-existing legislation and by adjusting executive guidelines instead.

Challenges of Rural Family Physician Policy in Iran.

As per the goals of the family physician program, it is essential to pay attention to the effectiveness and performance of FPP. Although the implementation of the FPP program is an important development in the discussion of rural health insurance and the provision of health services and referral systems in the country, the evidence suggests that by identifying challenges and taking appropriate action, this plan can be improved. This study aimed to investigate the challenges of rural Family Physician Policy (FPP) in northern Iran. This study comprised a mixed method. The former intended to identify the challenges of rural FFP using the narrative review method. To achieve a comprehensive list of challenges, a narrative review and content analysis were performed and semi-structured interviews were held with key stakeholders of FPP in the north of Iran, including physicians, managers, and policymakers. Identified challenges were categorized into eight categories including the weakness of the health insurance system, low comprehensiveness of executive guidelines, inappropriate recruitment and maintenance of human resources, weakness of cultural context, low efficacy of health information management system, poor educational effectiveness, inappropriate motivational mechanisms, and weakness of the referral system. As per the quantitative findings, "weakness of the referral system" and "inappropriate recruitment and maintenance of human resources" had the lowest and highest weaknesses, respectively. To address existing challenges in the rural FPP, a comprehensive plan of action should be developed with an emphasis on human resource management, health information management system, comprehensive rural health insurance, and legislation.

Kriterijumi za izbor odgovarajućih metoda analize kašnjenja (DAM) za mega građevinske projekte

Nowadays, one of the major sources of issues in the construction sector in the Middle East and North Africa (MENA) region is the Extension of time (EOT) claims, which is so hard to resolve. Authors and practitioners have started trials in numerous academic studies to show how to properly deploy Delay Analysis Methods (or "DAMs") and to give practitioners executive guidelines to support them with proper analyses and claim resolution. The awareness of the use of these methods is essential to realize their restrictions and capacity to fit in with various project circumstances and to select appropriate delay analysis methods. The main objective of this research is to provide a guide for the selection of appropriate DAM by defining a list of important criteria that have the most preference in choosing the effective method. These criteria will be rated by collecting feedback from experts in the MENA region through questionnaires. The survey was conducted in the United Arab Emirates (UAE) for the abundance of multinational firms working on mega construction projects with multicultural backgrounds and diversity of expertise in addition to the availability of carrying out interviews when needed and the widespread adoption of standard international construction contracts. Then, the possibility of ranking is calculated by using the Relative Importance Index (RII). This ranking will be considered as an important tool for the proper selection of convenient delay analysis methods. Ultimately this paper will facilitate the selection of appropriate DAM by Delay analyst through investigating project circumstances by mapping it with current ranked criteria.

Quality Assessment of Meta-Analyses on Cervical Cancer.

Meta-analysis (MA) quantitatively summarizes the findings of independent studies and is considered the highest quality of evidence for evidence-based medicine. However, issues in reporting and methodological rigor of MA hamper reproducibility and create the potential for bias. By applying PRISMA reporting guideline and AMSTAR2 execution guidelines on 40 cervical cancer MA samples covering topics such as interventions and risk factors, we determined the extent to which MA execution adhered to best practice guidelines. The results show that the elements with least adherence include "review methods established before MA" and "principal summary measures defined" (each 32.5% per PRISMA) and "characteristics of included studies" (31.3% per AMSTAR2) which undermine reproducibility and increase the risk of bias. This initial work presents common pitfalls in MA and is intended to improve awareness of these issues for clinicians who are interested in conducting MA and to pave the way toward quality improvement via informatics approaches.

Proposed marketing strategy to increase the revenue of a management consulting firms

The lack of execution guidelines is not the only problem faced by the consulting firms. They have other challenges to consult towards broad range of different segment and target, which each and every segment have their own characteristic, challenges, and difficulties. In its 4 years of company establishment, NAS realized that as any other newly developed company, it probably did not have the strong base for sustainable business. In this study, the author uses the AFI framework (Analysis, Formulation, and Implementation) in determining the right strategy to increase the competitiveness of NAS in the market. Primary data earned from quantitative research by spreading questionnaire to respondents and qualitative research by conducting depth interview for respondents to gain deeper insight as well as interview with an internal organization of NAS. Secondary data earned from articles, journals, and company data. The result shows that although NAS revenue has continued to increase since the first of its establishment, after analyzing one of the revenue clusters, it turns out that the largest NAS revenue does not come from consulting activities which are the main service of NAS itself, while market research which is a supporting service from NAS occupies the first position by donating 37 persen average income in the period 2018-2021. An even more surprising figure is that 34 persen of the average NAS revenue comes from service provider activities that are not part of the NAS core services and only acts as a single, unsustainable service activity.

A Data-Driven Fragmentation Model for Carbon Therapy GPU-Accelerated Monte-Carlo Dose Recalculation.

The advent of Graphics Processing Units (GPU) has prompted the development of Monte Carlo (MC) algorithms that can significantly reduce the simulation time with respect to standard MC algorithms based on Central Processing Unit (CPU) hardware. The possibility to evaluate a complete treatment plan within minutes, instead of hours, paves the way for many clinical applications where the time-factor is important. FRED (Fast paRticle thErapy Dose evaluator) is a software that exploits the GPU power to recalculate and optimise ion beam treatment plans. The main goal when developing the FRED physics model was to balance accuracy, calculation time and GPU execution guidelines. Nowadays, FRED is already used as a quality assurance tool in Maastricht and Krakow proton clinical centers and as a research tool in several clinical and research centers across Europe. Lately the core software has been updated including a model of carbon ions interactions with matter. The implementation is phenomenological and based on carbon fragmentation data currently available. The model has been tested against the MC FLUKA software, commonly used in particle therapy, and a good agreement was found. In this paper, the new FRED data-driven model for carbon ion fragmentation will be presented together with the validation tests against the FLUKA MC software. The results will be discussed in the context of FRED clinical applications to 12C ions treatment planning.

Ethanol test as a determinant of physiological potential of forest species seeds: The case of Plathymenia reticulata Benth. (Leguminosae-Mimosoideae), a tree of interest for Atlantic Forest restoration

Abstract: The ethanol test supplies information on physiological problems related to seed deterioration. The test optimization is crucial for its application in the seed analysis routine. This study aimed to evaluate vigor test for Plathymenia reticulataseeds based on ethanol production in order to establish execution guidelines and verify its relationship with other seed vigor tests. Seed lots were subjected to germination and vigor tests, and seed coat evaluation. Ethanol production assessment was carried out based on two trials testing water volumes for imbibition (0.25; 0.5; 0.75; 1.00; and 1.25 mL), reading periods (2, 4, 6, 8, 24, and 48 h), and seed quantities (5, 10, and 15). There was a distinction in physiological potential between the lots, indicated by the ethanol test and other traditionally used tests. The ethanol test was efficient for vigor assessment in Plathymenia seeds, as were the other vigor tests, when conducted with 15 seeds imbibed in a volume of water 2.5 times their mass for 48 h. The vigor test based on ethanol production proved reliable and it is recommended for use in a system of seed production and commercialization in nurseries and forestry companies.

95 DOCUMENTATION OF URINARY CATHETER INDICATION AND INSERTION PROCEDURE FOR MEDICAL INPATIENTS AT A UNIVERSITY TEACHING HOSPITAL

Abstract Background Approximately 25% of inpatients have urinary catheters at some point during their hospital stay; over half are deemed inappropriate. This is significant as catheter-associated urinary tract infections (CAUTI) increase morbidity, mortality and length of hospitalisation. Lack of medical documentation and clinician awareness of catheters have been identified as risk factors for inappropriate catheterisation. The aim of this audit was to assess inpatient urinary catheter use among medical inpatients to determine if the indication and insertion procedure were clearly documented. Methods The audit was conducted over one day and included all medical inpatients aged 18 years and above. Emergency Department and High Dependency patients were excluded. Data was collected using standardised data collection sheets and involved a review of medical/nursing notes. Data was benchmarked against Health Service Executive guidelines. Results 27 of 132 medical inpatients (20%) had a urinary catheter in situ on the day of audit. 37% (n = 10) had long-term urinary catheters in situ prior to admission and are not considered further. Of the remaining 63% (n = 17), 9 were female (53%), 8 were male (47%), and the average age was 75 years. Indication was documented in nursing notes for 76% and in medical notes for 53%. Indications included monitoring urinary output (29%), urinary retention (24%), sepsis (18%), comfort (6%) and haematuria (6%). Catheter insertion procedure was documented in nursing notes for 59% and in medical notes for 12%. Conclusion One fifth of medical inpatients had urinary catheters on the day of audit. 63% of these patients did not have a catheter prior to admission. Overall medical documentation of catheter indication and insertion procedure is poor. Better documentation would likely improve clinician awareness of their patient’s catheters and prompt earlier review of appropriateness. Education sessions, insertion proforma stickers and catheter review reminder systems are suggested to improve documentation.

Strategic Study of On-Line Reading Clubs in Senior High School Libraries of Taiwan

In this 21st century, information flow has already reached a matured level. It is the time to promote on-line reading clubs, as high school students generally possess the ability to study by themselves through the internet. In 1990, Taiwan Ministry of Education announced the plan to practice inter-schools on-line reading clubs for all high schools and constructed the students’ website to achieve a significant milestone for on-line reading clubs on campus. The on-line reading clubs are running through interactive web pages, electronic book stores, discussion boards, knowledge sharing etc. The essence of these clubs is the combination of key elements: reading, materials and communication. In this research, we first conduct with questionnaire and interview approaches to study their current situations, executive guidelines, resource requirements, performance evaluations and operating strategies of on-line reading clubs in Taiwan. Then we give a blueprint of well-function on-line reading club web environment to encourage students to involve in the clubs and cultivate inter-school reading. Finally, we propose strategic suggestions for practicing on-line reading clubs in senior high school libraries.

The development of a performance measurement system for indirect procurement: a Delphi study

PurposeThis study aims to address the current gap in knowledge of indirect procurement performance management. It attempts to argue the need for a specific and tailored performance management approach for the indirect procurement function that incorporates a balanced approach, beyond financial measures.Design/methodology/approachThe case study approach evaluated key performance indicators from a balanced scorecard (BSC) perspective in the development of a performance measurement system (PMS) for a Middle Eastern university’s indirect procurement division. It initially reviewed the literature to assess potential indicators for this context. It used vision and mission statement analysis alongside expert interviews to augment the literature. The candidate indicators were then evaluated and ranked by an expert panel through applying a four-round Delphi technique.FindingsTwenty-nine procurement-specific indicators are suggested in a BSC framework. The five highest-ranked indicators were not in the financial perspective unlike other BSC studies in the broader field of supply chain management (SCM).Practical implicationsThe study suggests a framework and indicators for a procurement PMS for practitioners to consider. It also highlights there is no one-size-fits-all and that organisations need to tailor PM to the organisation and divisional strategy and operational needs. This study aids the development of guidelines for executives and procurement management that wish to develop indicators and a PMS.Originality/valueThis study contributes to knowledge by partly addressing the under-researched field of indirect procurement PM. The literature suggested that various roles in SCM require specific PM indicators. This study puts forward a BSC framework with 29 indicators specifically for indirect procurement. Fourteen of these indicators were derived from non-literature sources. This study enhances knowledge and contributes to the limited debate and evidence on indirect procurement PM and the broader PM literature.

The significance of intellectual capital in strategies of transnational corporations

Abstract Objective This study is an attempt to identify crucial assets of intellectual capital (IC) of transnational corporations (TNCs). The author identifies key assets each of the IC layers: organizational, innovative, and institutional. Examining these complex constructions of IC and its comprehensive influence on achieving competitive advantage is justified as the topic has been investigated rarely till now. Methods The paper presents literature review and the results of an authorial survey (252 corporations). The author used the following methodology concepts: the Grounded Theory Method, the Social Network Analysis, and the Multidimensional Statistical Analysis. Findings The results of the conducted analysis do sustain the postulated hypothesis that the main pillars constituting the intellectual capital of the most powerful transnational corporations (leaders) are the same in terms of the core irrespective of the type of industry. Based on the conducted research, the author points to the three key requirements for each of three IC layers (organizational, innovative, and institutional). Practical implication The proposed model of layers of intellectual capital may be used to identify the relationship in question, or its lack of relationship, in other types of international business. Furthermore, the study results provide guidelines for executives of corporations with respect to intellectual capital management. Originality/value It is a new, original proposal for measurement and presentation of the relationship between international competitiveness of transnational corporations and their intellectual capital efficiency (pillars of IC-layers).

Reduction of hazardous SO2 into elemental sulphur over chicken eggshells-derived calcium-based redox agent: A systematic step-by-step thermodynamic analysis and process validations

Current work demonstrated the thermodynamic feasibility of SO2 reduction into elemental S via catalytic reaction-regeneration loop over chicken eggshells-derived Ca-based redox agent, while the experimental results were presented subsequent to thermodynamics analysis for validating purpose. Ideally, CaS, engineered from chicken eggshells, would facilitate the SO2 reduction upon oxygen-transferring process, resulting in CaSO4 and sulphur solid. Thermodynamic investigations via minimization of Gibb’s Energy (ΔGmin) were initiated with the development of Ca-based redox agent from modelled chicken eggshells, followed by pre-treatment of redox agent and finally the SO2 reduction reaction. Based on the thermodynamic analysis, Chicken eggshell, modelled by CaCO3, is mainly converted into functionalized CaS through dual-sulphurization process, favorably at mild temperature of 623–1023 K. At optimum 1023 K, the obtained product thermodynamically consists of CaSO4 (74.97%) and CaS (24.79%), which required further treatment to maximize CaS content prior to SO2 reduction reaction. H2- and CO-reductions indicate that conversion into 100% of desirable CaS are thermodynamically feasible, with H2-reduction preferred due to its lesser exothermic behavior. As for the SO2 reduction, CaS exhibits an excellent activity in reducing SO2 to elemental S (S2–S8) at relatively low temperature of 723–973 K, with exceptionally high yield (>99%). Upon increasing temperature (>1173 K), adverse effects to both SO2 conversion and sulphur yield were observed, implying the impracticality in laboratory executions. Simple, yet powerful experiments were conducted, subsequently validated the thermodynamic estimations in current study. This systematic study comprehensively investigated and justified the feasibility of entire process, hence providing provisional guidelines for the future execution of laboratory works.
