A Prefeasibility Study for the Adaptive Reuse of Cultural Historical Landscapes as Drivers and Enablers of Sustainable Development

The international scientific debate on the growing concern over land consumption has gained prominence in recent years. The awareness of the link between cultural heritage and sustainable development has become increasingly evident, leading to a greater focus on the Adaptive Reuse (AR) of cultural assets as a conscious process of creating new values. This trend has prompted a reflection on urban planning practices and the promotion of AR and valorization policies for heritage, which can contribute to environmental sustainability, social cohesion, and cultural identity, thereby providing fertile ground for innovation and local economic development. However, decisions regarding AR interventions pose significant complexity due to the multiple interests at stake, as well as high costs that discourage investiments. For these reasons, this paper proposes a multi-methodological approach—applied to a project for the AR of a cluster of mountain huts located in the Sila National Park (SNP)—aimed at effectively supporting decisions related to the evaluation of feasibility and economic sustainability of cultural heritage landscapes that have not yet been adequately valorized. This approach was applied to a pilot project of AR, allowing for the discussion of the proposed evaluation methodological framework. The final step involved verifying the economic feasibility and financial sustainability of the methodology based on a Financial Feasibility Plan (FFP) of the proposed of the new destination to ‘Rifugio Diffuso’ (RD). The assessment aimed to evaluate the intervention’s ability to create value, generate a level of profitability that meets private investment expectations, and promote sustainable development of the local economy.

Development and Pre-Feasibility Testing of SPECIFiC: A Psychoeducation Programme for Caregivers of Children with Fetal Alcohol Spectrum Disorder (FASD)

A growing number of evidence-based services are available for fetal alcohol spectrum disorder (FASD), but few focus on caregiver psychoeducation. Despite new guidance in the UK requiring FASD services, the evidence base for effective interventions is currently lacking. An FASD caregiver training program would be a novel and valuable addition to service provision. SPECIFiC (Salford parents and carers education course for improvements in FASD outcomes in children) was developed using an evidence-based logic model with input from clinicians, families, and the charity sector. The course was delivered online to a small number (n = 9) of families in a mixed-methods, exploratory pre-feasibility study. Families were represented by either one or two caregivers, all of whom were adoptive parents or special guardians of a child with FASD. Parent perceptions were assessed using semi-structured interviews. The performance of proposed outcome measures (stress, psychological functioning, parenting self-efficacy, knowledge of FASD, and child behavioral difficulties) was evaluated. Pre- and post-measures were acceptable and showed promise as outcome measures for a future trial. Participants spoke positively about the course, welcomed the opportunity to discuss their own situations with other FASD caregivers, found the advice to be immediately useful, and described the course as therapeutic. Suggestions for improvements tended to focus on timing and technical issues. Based on a small sample, SPECIFiC was shown to be an acceptable and feasible psychoeducation program. Further evidence from a randomized controlled trial is needed to evaluate whether SPECIFiC can lead to reduced stress in parents, improved parenting self-efficacy, and ultimately a reduction in children’s behavioral difficulties.

Evaluating the performance of Indonesia’s nuclear energy program using INPRO methodology

Abstract A project was initiated to assess the sustainability of Indonesia’s planned nuclear energy system using the IAEA INPRO Methodology to develop an awareness of sustainability issues to support nuclear energy development strategic planning and decision making. Accordingly, for a nuclear energy system to be sustainable, fulfilment of current needs should not compromise the ability of future generations to meet theirs. The sustainability of the planned nuclear energy system was assessed based on the basic principles, user requirements and criteria in the areas of economics, infrastructure, waste management, proliferation resistance, physical protection, environment, and safety. The assessments covers the sustainability of a large reactor completed in 2014 to support the Pre-Feasibility Study in Bangka Belitung, and of a small and medium-sized reactor (SMR) currently ongoing to support the study in West Kalimantan. The results indicate that evidence of achieving sustainability exists in many respects, but there remain gaps to be addressed in due time on aspects such as economics, investment climate, availability of technology, and global development on non-renewable resources. A preliminary study on fuel cycle arrangements is being performed in parallel, focussing on collecting data including on fuel cycle services abroad. Collecting data has been the main challenge for a newcomer country that has yet to decide on the exact reactor technology. The paper is intended to evaluate the performance of Indonesia’s nuclear energy program using the INPRO Methodology to address the sustainability of its planned NES, i.e., reactors and fuel cycle facilities, and to evaluate the effectiveness of the efforts to achieve the purpose. Awareness of sustainability issues plays a key role in nuclear energy policy, especially for determining the energy mix by 2040, to achieve the Net Zero Emission policy target by 2060 or earlier.

The surface challenges of underground hydrogen storage – pre-feasibility studies at the Otway International Test Centre, Victoria

Underground hydrogen storage (UHS) has the potential to overcome the infrastructure and safety challenges of large-scale hydrogen storage, support long-term supply security and decrease delivery costs through economies of scale. Depleted hydrocarbon reservoirs and saline aquifers are likely to be significant contributors to UHS capacity in Australia. The principles of subsurface hydrogen storage in porous reservoir rocks are based on experience from both natural gas and carbon dioxide storage projects. However, as field-scale testing is required to demonstrate and mature the technology, a pre-feasibility study of the potential for an early UHS demonstration at the Otway International Test Centre (OITC) has been undertaken. Pre-feasibility studies have shown that while the characterisation of the subsurface storage reservoir is the most important aspect of the site-selection process, above-ground factors, such as facilities design, the logistics of hydrogen supply and the regulatory environment, significantly affect project design. Existing technologies require only minor adaptation to provide the surface infrastructure for a UHS project, but the logistics of hydrogen supply may be a significant factor in the scope of a demonstration project.

Liquid-liquid extraction of molybdenum(VI) using aqueous two-phase systems (ATPS) consisting of polyethylene glycol (PEG) and sodium, ammonium and copper(II) salts: Comparison with conventional solvent extraction

In this work, the stripping of molybdenum from aqueous two-phase aqueous systems (ATPS) formed by a mixture of polyethylene glycol (PEG) 4000, salt and water was studied at different operational conditions of pH (7, 8 and 9) and temperature (308.15, 323.15 and 338.15 K), using two molybdenum salts (Na2MoO4 and (NH4)6Mo7O24). These salts were used for the experimental tests of extraction and stripping of the two-phase aqueous system of PEG 4000, CuSO4 and water, to evaluate the best percentage of stripping using different stripping agents: NaOH, Na2CO3, CuSO4 and a mixture of (NH4)2SO4 and NH4OH (Khayati et al., 2011). According to the results, the best stripping agent was the 20% (NH4)2SO4 solution as phase former plus 25% NH4OH as pH modifier. The experimental results indicate that the increase in temperature is directly proportional to the percentage of stripping. For the system of PEG 4000, CuSO4, water, Na2MoO4, (NH4)2SO4 and NH4OH system (ATPS 1) the percentage of stripping was 96.3%. In the case of PEG 4000, CuSO4, (NH4)6Mo7O24, water (NH4)2SO4 and NH4OH (ATPS 2) the stripping was 99%, these being the maximum values of stripping at pH = 2 and T = 308.15 K.It was determined that for ATPS 1, as the pH increases the stripping efficiency tends to decrease, while as the pH increases in ATPS 2, the stripping efficiency increases; this behavior is attributed to the hydration energy of the ions. Finally, a pre-feasibility study of the studied processes, ATPS 1, ATPS 2 and traditional solvent extraction (SX), was carried out, which included calculation of the profit factors.

Agricultural Grid Connected Photovoltaic System Design and Simulation in Egypt by using PVSYST Software

Agricultural Photovoltaic Systems are a key technology to achieve sustainable development goals by reducing competition between land for food and electricity. In addition, Agricultural Photovoltaic Systems are at the heart of the link between power generation, crop production and irrigation water conservation. The main ecophysiological constraint on crop production under photovoltaics is the reduction of light. It is difficult to recommend shade tolerance for some plant varieties due to insufficient information on shading conditions for most plants. The use of shading panels (photovoltaic panels) requires more crop-specific research to determine the optimal percentage of panels and their placement that will not reduce agricultural yields. Crop yield variation versus field shading and availability to maximize the system require extensive research. This study aims to develop a standard procedure for designing an agricultural grid-connected photovoltaic power generation system for solar power generation in an agricultural area in Bahteem, Egypt. The technical and annual performance of the grid-connected PV system was simulated using PV Syst software. The paper started with a pre-feasibility study of a grid-connected photovoltaic system using PV Syst. Software with an extensive database of meteorological data, including global daily horizontal solar irradiance, and a database of various renewable energy system components from different manufacturers. In this work, a comprehensive literature review of agricultural solar photovoltaic systems is conducted, with a particular focus on grid-connected systems, followed by a design procedure for grid-connected solar photovoltaic systems. The planned photovoltaic system will generate a total of 400 KWp of electricity. This generated electricity can drive down electricity prices by exporting excess electricity to the national grid. In addition, solar power systems are fuel-efficient and have a low environmental impact.

Pre-Feasibility Study of a Multi-Product Biorefinery for the Production of Essential Oils and Biomethane

Rural areas can benefit from the development of biorefineries for the valorization of endogenous feedstocks. In this study, a pre-feasibility assessment of an integrated multi-product biorefinery to produce essential oils and biomethane is carried out considering current technical and economic conditions. The proposed concept is based on the steam distillation of forestry biomass for the extraction of essential oils (2900 L/y) followed by biomethane production via syngas methanation using the spent biomass as feedstock (30.4 kg/h). In parallel, the anaerobic treatment of WWTP sludge (5.3 kg/h) is used to produce additional biomethane for mobile applications. The results show that the intended multi-product biorefinery delivers attractive benefits for investors as described by the calculated financial indicators: NPV of EUR 4342.6, IRR of 18.1%, and PB of 6 years. Overall, the pre-feasibility analysis performed in this study demonstrates that the proposed biorefinery concept is promising and warrants further investment consideration via cost and benefit analysis, ultimately promoting the implementation of multi-product biorefineries across Europe.

Renewable methanol production from green hydrogen and captured CO2: A techno-economic assessment

This paper aims to present a pre-feasibility study of a power-to-fuel plant configuration designed for the production of 500 kg/h of renewable methanol (e-methanol) from green hydrogen and captured carbon dioxide. Hydrogen is obtained by water electrolysis employing the overproduction of renewable electricity. Carbon dioxide is assumed to be separated from the flue gas of a conventional power station by means of an amine-based CO2 absorption system. A comprehensive process model has been developed with the support of Aspen Plus tool to simulate all the plant sections and the overall system. After the process optimization, a detailed economic analysis – based on capital and operating costs derived from commercial-scale experience and assuming a 20-year lifetime – has been performed to calculate a levelized cost of methanol (LCoM) of 960 €/t (about 175 €/MWh). The analysis confirms that, today, the technology is still not competitive from the economic point of view, being LCoM more than double than the current methanol price in the international market (450 €/t). However, it indicates that the process is expected to become competitive in a mid-term future, as a consequence of the new European policies. The study also reveals that LCoM is mainly affected by the electricity price and the electrolyser capital cost, as well as the capacity factor of the plant.

Pre-Feasibility Study of Carbon Sequestration Potential of Land Clearing Stumps Buried Underground

Stump harvesting for energy has decreased in Finland, and many heat and power plants no longer accept stumps in their fuel portfolio due to fuel quality problems. However Finland is a forested country, and land clearing stumps need to be extracted, e.g. in infrastructure construction projects. If stumps cannot be used for energy production, they are dumped in landfills, where they start to decay and release CO2 into the atmosphere. One option to avoid CO2 emissions would be the burying of stumps underground so that the decaying process of wood would be inhibited in anaerobic conditions. The aim of this study was to define the carbon sequestration potential of stump burying logistics and calculate their CO2-eq emissions to compare them with the emissions of decaying stumps in piles. The analysis was performed as a spreadsheet-based system analysis at a worksite level as a function of time and size of extracted stumps. As a result of the analysis, the emission effiency of the logistics chain based on stumps stored below the ground was good. The net carbon stock varied between 743.7 and 775.0 kg CO2-eq/m3 as a function of stump diameter, when the emissions of the stump burying logistics chain were 49.0 and 17.7 kg CO2-eq/m3 respectively. In the case of a Finnish municipality with an annual accumulation of 1000 m3 of land clearing stumps, the carbon sequestration potential of stumps buried underground is equivalent to the emissions of between 280,000 and 290,000 liters of diesel fuel consumption, depending on the diameter of the extracted stumps and the diesel fuel emission factors for different engine and diesel fuel types.

An estimation of bio-methane and energy project potentials of municipal solid waste using landfill gas emission and cost models

PurposeThe purpose of the study is to analyse municipal solid waste (MSW) disposed of in Jimeta-Yola metropolis for landfill gas (LFG), methane and project viability potential.Design/methodology/approachThe data was collected daily from landfills for four weeks. About 7,329.55 Mg/year of waste was analysed. These waste were separated into bio-degradable components i.e. paper and textile (263.66 Mg), non-food organic (681.45 Mg), wood and straw (189.50 Mg) and food and kitchen waste (1797.20 Mg). Non-degradable components include plastics, polythene bags, metals, sand, stones, cans etc. (4397.73 Mg). The component's characteristics such as a number of samples, weight, volume, landfill age etc. were measured. The waste, methane (CH4) and energy potential were also analysed using LFG energy cost model.FindingsThe landfills received 15 Gg/year of MSW and emit 0.31 Gg/year of LFG having CH4 content of 82.95 Mg in 2016. These can produce 33.78 GWh of heat energy equivalent to 10.14 GWh of electricity analytically. Therefore, between 2016 and 2022, about 2.24 Gg CH4 and 5201.32 MWh of electricity were wasted. Henceforth, proper management of these waste substances can produce 186.4 Gg CH4 which will generate 432.52 GWh of electricity. The most economically viable project is an electricity project generating 418 kW/year at a sale price of $1.14/kWh (58.38/kWh) and a payback period of 11 years.Practical implicationsRaw LFG collected can be used in heating brick kilns, boilers, furnaces and greenhouses. When treated, the LFG can produce renewable natural gas (RNG), which is used in energy generation and various domestic, vehicle and industrial applications.Social implicationsThe analytical energy generation can provide gross revenue of ₦19.46bn at an average of ₦192.71million/year. Using Landfill Gas Emissions Model (LandGEM) model, the gross and net revenue will be $0.42m and $0.28m yearly, respectively. The project can provide jobs and economic boost to the immediate community through associated ripple effect.Originality/valueThe research is a pre-feasibility study for LFG to gas or electricity projects in Jimeta-Yola. The study contributed to the body of knowledge as a source of literature for further studies locally and globally.

Home-Based Robotic Upper Limbs Cardiac Telerehabilitation System.

This article proposes a new, improved home-based cardiac telerehabilitation system enhanced by a robotic and Virtual Reality module for cardiac patients to be used in their rehabilitation program. In this study, a novel strategy was used to integrate existing equipment and applications with newly developed ones, with the aim of reducing the need for technical skills of patients using remote control. Patients with acute or chronic heart diseases require long-term, individualized rehabilitation in order to promote their motor recovery and maintain an active and independent lifestyle. This will be accomplished by creating a system for at-home cardiac telerehabilitation augmented by a VR and cobot systems, which can be used long-term at home by each individual patient. In the pre-feasibility study carried out on healthy volunteers familiar with software applications and robotic systems, we demonstrate that RoboTeleRehab could be technically feasible both hardware and software.

Strengthening the biogas sector of Ethiopia through international collaboration: the case of the Digital Global Biogas Cooperation (DiBiCoo)

Even though biogas technology was introduced in Ethiopia in 1957, the technology is still in its infancy stage with more than 98 % of biogas plants installed in Ethiopia at a small- scale level and used for cooking and lighting applications. The Digital Global Biogas Cooperation (DiBiCoo) project facilitates collaboration between European biogas industries and stakeholders from emerging and developing markets through the development and application of innovative digital and non-digital support tools, knowledge transfer and capacity building. The Digital Global Biogas Cooperation helped the Ethiopian biogas sector through capacity building trainings, creating a digital biogas and gasification matchmaking platform to link companies with local biogas actors in the country, and assisting demo case projects up to prefeasibility study stage. Furthermore, it provided practical exposure through virtual and in person biogas plant tour in several countries, and generating several documents related to the Ethiopian biogas sector including an assessment on biogas potential, financial options and a legal frame work to assist the sector. Based on this collaboration, more than 30 stakeholders participated in 11 web seminars, 2 capacity-building trainings, 3 days business model development training in Biogas and more than 10 virtual study tours. One demo case and three- follower cases prefeasibility studies were supported. Thus, the Digital Global Biogas Cooperation is providing much needed support to the biogas sector of Ethiopia.

Analysis of the market of mine support systems in Russia

The analytical results on the current condition and growth prospects of the market of mine support systems in Russia are presented. The scope of the analysis involved all available and open sources of information: databases of the Federal Customs Service and of the Federal Service for State Statistics of the Russian Federation; regulatory documents in open access; printed and electronic business materials and analytical reviews; global Internet; expert inquiries; information provided by the participants of the domestic and international markets; research data of marketing and consulting agencies; databases of sectoral institutions; pricing monitoring results; research papers and proceedings of scientific conferences. The present-day business climate in the mining industry in Russia is assessed. The major importers of mine support systems and the average price dynamics of the relevant imports for the last 5 years are identified. The vulnerable spots are detected on the Russian market, namely, the lack of the pre-feasibility study procedures of new, innovative and expensive systems and types of mine support; the lack of testing machines to estimate and demonstrate operation of different mine support systems and types under static and dynamic loading with a view to determining their energy absorption capacity and deformation characteristics, etc. The mineral resources and mineral reserves of Russia are evaluated per regions of the country. The information on production of mine support systems in Russia is given together with the review and characteristic of the suppliers, as well as with the procedure and sequence of mine support system certification in Russia. The manufacturers of sheet and rolled products, metal (forged) female screws, special structural iron and H-beams are listed. Based on the analytical results on the market of mine support systems in Russia, at the current stage of development of the mining industry, the Russian manufacturers and suppliers of mine support systems have good prospects for the effective internal marketing of the products and for engineering of innovative systems and materials. These prospects are for the first turn connected with: the ability to completely supply production with domestic rolled products, structural iron and other required materials; the elimination of imports of such products from unfriendly countries; the stiffening of the government supervision over safety in mining; and with the concern of the scientific community in Russia for engineering and design of novel and nonstandard mine support systems for different geological and geotechnical conditions. The 2021 Report on the Market of Mine Support Systems in Russia and Kazakhstan includes a substantial volume of statistical data on all essential areas and topics. The report is available on request at the Research Center for Applied Geomechanics and Convergent Technologies in Mining of the NUST MISIS’ College of Mining.

Assessing technical capacities and economic efficiency of granulated middling hydraulic transportation as applied to Kursk Magnetic Anomaly deposits development

Introduction. The majority of iron ore open pits in Russia and the CIS belong to the category of deep open pits, same as prospective Kursk Magnetic Anomaly (KMA) deposits (Prioskolskoye, Chernyanskoye, Pogrometskoye, etc.) with the thickness of overburden equal to 100–150 m where the open pits will be deep already at the early stage of mining operations. Research objective is to provide rationale for hydraulic transportation advantage over other types of industrial transport and identify technical capacities and economic efficiency for a new scheme of opencasting and transport of promising fields of KMA at the stage of the pre-project development. Research objects are Prioskolskoye and Chernyanskoye deposits. The main methods of research were the graphic method, graphic-analytical method and method of technical and economical comparison of different options. The basis of the proposal for development of the prospective KMA deposits is a new layout of the industrial site of a miningand-processing facility with location of parts of the crushing and grinding complex in the open pit and hoisting of ore in the form of pulp to the surface by pipeline transport for further beneficiation. Results. In general, the prefeasibility study involving the technical and economical comparison of two prospective KMA deposits shows cost savings with regard to ore transportation from the open pit to the industrial site by hydraulic transport compared to the cyclic-flow technology. The new technology enables reduction of the transportation costs by 1,5–2 times and increase in labour productivity with regard to ore transportation by 2–3 times.

It is known that the effective functioning of the railways depends on their load-bearing capacity, and therefore, special attention is paid to the pre-feasibility study and the payback period of the capital investments invested in the works during the capital investments of the railways. Because the operation of railway lines is associated with significant costs, its existence within the allowable limits of its size requires periodic evaluation and planning and implementation of engineering measures. The essence of the problem created by the operation of lowload railways of the world and Georgian railways are discussed. The main reasons for the deterioration of the operating data of these railways are reviewed. Low load railway lines are separated throughout the Georgian Railway and their total length and percentage composition in the overall railway network of the country are determined. The article outlines the main trends in the operation of low-load railways identified as a result of the analysis of foreign experience and presents four strategies based on this trends. Not yet established state approach to the use of LLRL infrastructure in Georgia can be based on the above mentioned stratages. It is noted that each of the proposed strategies has different efficiencies and selection conditions, so it should be considered according to the problems of each low-load rail section with innovative and / or traditional approaches to develop adaptive mechanisms for the operation of low-activity railway lines.

Usability and acceptability of a cognitive training intervention (SMART) for people with multiple sclerosis (MS): A prefeasibility formative evaluation.

Multiple sclerosis (MS) is a chronic autoimmune, inflammatory neurological disease of the central nervous system (CNS), increasing in incidence and prevalence across both developed and developing countries. Cognitive difficulties are common in MS sufferers with 70% experiencing difficulties in higher-level brain functioning such as planning, attention, problem solving, and memory. Computerised cognitive training programmes may hold promise as a treatment option for improving cognitive function in people with MS, subject to exploring and addressing potential barriers to usability and acceptability. This study aimed to test the usability and acceptability of a computerised cognitive training intervention-Strengthening Mental Abilities Through Relational Training (SMART) -for people with MS, through a mostly qualitative prefeasibility design ( n= 12). There were two phases of testing: (1) initial usability testing via a think-aloud protocol ( n= 6) and (2) alpha-testing to assess experienced acceptability over a four-week period of engagement ( n= 6). Data from the two phases were subjected to Framework Analysis, wherein we deductively applied the Health IT Usability Evaluation Model and Theoretical Framework of Acceptability to assess usability and acceptability, respectively. Results show SMART to have satisfactory usability with participants reacting positively to the formatting, visuality, and process of the interface. Minor suggestions were made on how best to adapt SMART for people with MS, but the programme and facilitative support were generally perceived to be acceptable, with participants expressing positive feelings about taking part in the intervention, despite associated burdens. This prefeasibility study provides preliminary evidence of the usability and acceptability of SMART as a computerised cognitive training programme for people with MS. We conclude that we can now move forward with a feasibility trial of SMART, with the intention of proceeding to a definitive trial with cost-effectiveness analysis.
