Abstract Geothermal energy, a form of renewable energy, has been extensively utilized for building heating. However, there is a lack of detailed comparative studies on the use of shallow and medium-deep geothermal energy in building energy systems, which are essential for decision-making. Therefore, this paper presents a comparative study of the performance and economic analysis of shallow and medium-deep borehole heat exchanger heating systems. Based on the geological parameters of Xi’an, China and commonly used borehole heat exchanger structures, numerical simulation methods are employed to analyze performance and economic efficiency. The results indicate that increasing the… More > Graphic Abstract

Abstract This research investigates the design and optimization of a photovoltaic (PV) water pumping system to address seasonal water demands across five locations with varying elevation heads. The system draws water from a deep well with a static water level of 30 m and a dynamic level of 50 m, serving agricultural and livestock needs. The objective of this study is to accurately size a PV system that balances energy generation and demand while minimizing grid dependency. Meanwhile, the study presents a comprehensive methodology to calculate flow rates, pumping power, daily energy consumption, and system capacity.… More >

Abstract In this study, a model of combined cooling, heating and power system with municipal solid waste (MSW) and liquefied natural gas (LNG) as energy sources was proposed and developed based on the energy demand of a large community, and MSW was classified and utilized. The system operated by determining power by heating load, and measures were taken to reduce operating costs by purchasing and selling LNG, natural gas (NG), cooling, heating, and power. Based on this system model, three operation strategies were proposed based on whether MSW was classified and the length of kitchen waste… More > Graphic Abstract

Abstract Objective: To use data from a randomized controlled trial and update an earlier economic evaluation of surgery versus collagen injection for the treatment of female stress urinary incontinence (SUI).
Materials and methods: A decision tree model was developed using probabilities of success and complications from a randomized controlled trial. Resource use and cost data were taken from the earlier economic evaluation. The primary outcome was treatment success, which was defined as a negative 24 hour PAD test given 1 year post-treatment. The evaluation was conducted from the 'healthcare system' perspective and separate analyses were undertaken for Ontario… More >

Abstract Objective: The Proscar Long-Term Efficacy and Safety Study (PLESS) and the Medical Therapy of Prostatic Symptoms (MTOPS) study provide new evidence regarding the benefits of finasteride in the treatment of benign prostatic hyperplasia (BPH). The objective of this study was to utilize data from the PLESS and MTOPS studies to assess the cost-utility of finasteride and finasteride in combination with doxazosin, compared to doxazosin alone in men with moderate to severe BPH symptoms.
Methods: A semi-Markov decision analytic model was constructed to estimate the clinical consequences, costs and cost-utility of doxazosin, finasteride, and combination therapy. Analyses were… More >
