The analysis of long-term borehole heat exchanger system exploitation
Computer Assisted Methods in Engineering and Science, 2017 The key issue in designing borehole heat exchangers (BHE) is the long-term performance of the ground source heat pump (GSHP) systems. The performance directly reflects economic profitability and depends on a large number of parameters including rock ...

Heat Transfer Modeling of the Ground Heat Exchangers for the Ground-Coupled Heat Pump Systems [PDF]
, 2012 Ground-coupled heat pump (GCHP) systems have been gaining increasing popularity for space air conditioning in buildings due to their reduced energy and maintenance costs. The efficiency of GCHP systems is inherently higher than that of the traditional options because it utilizes the ground which maintains a relatively stable temperature all the year ...

Methodology for estimating the ground heat absorption rate of Ground Heat Exchangers
Energy, 2017 Abstract In Ground Source Heat Pump systems, the heat exchange rate is an important factor with regard to the initial cost of the system. When the Ground Heat Exchanger (GHE) is installed in a lithology with high thermal properties in the presence of groundwater, the heat exchange rates are larger than in the cases with poor thermal response of the ...

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Lessons Learned from Labyrinth Type of Air Preconditioning in Exergy-Aware Solar Greenhouses
Journal of Sustainable Development of Energy, Water and Environment Systems, 2022 An exergy-based model hypothesizes that labyrinth-type ground-to-air heat exchangers are responsible for carbon dioxide emissions if the exergy of power demand concerning ancillaries like fans and pumps exceeds the thermal exergy gain.

Research on ground-coupled heat exchangers [PDF]
International Journal of Low-Carbon Technologies, 2010 Ground source heat pump (GSHP) has been considered as one of the most promising low-carbon technologies for building heating, ventilation and air conditioning (HVAC) applications at present. Since a GSHP relies heavily on the performance of ground-coupled heat exchangers (GCHEs), this paper was focused on GCHEs key technical issues and presented ...

FEBS Letters, EarlyView.The process of internalization of the Shiga toxin A subunit via formation of a complex with the Shiga toxin B subunit, which specifically binds to the Gb3 receptor. The peptide is designed to act as a carrier of drugs into cancer cells. Here, we explored the potential of peptides derived from the catalytic A subunit of Shiga toxin (STxA) to be drug ...
