Analysis of the rule of window-to-wall ratio on energy demand of residential buildings in different locations in China [PDF]

Heliyon, 2023
Building energy demands are influenced by the window-to-wall ratio (WWR). The impact of the WWR on the energy demand in the same area has been researched by software. However, the impact of the WWR on the energy demand of buildings in different locations

Response Surface Methodology using desirability functions for multiobjective optimization to minimize indoor overheating hours and maximize useful daylight illuminance [PDF]

Scientific Reports
Improving thermal comfort often impacts daylight, creating trade-offs that remain underexplored, particularly in tropical dwellings. Overheating metrics—essential for assessing thermal conditions in warm regions—are entirely absent from daylight ...

Project of NNbar Experiment at the WWR-M Reactor [PDF]

KnE Energy, 2018
Supersource of ultracold neutrons on the basis of superfluid helium is under construction in PNPI NRC KI. It must provide UCN density 2-3 orders of magnitude higher than existing sources. For the new source we propose an experiment on search for neutron–antineutron oscillations based on the storage of ultracold neutrons in a material trap.

Optimizing irradiation conditions for natural molybdenum in WWR-K reactor

Nuclear Engineering and Technology
The production of the radioisotope molybdenum-99 in the WWR-K research reactor is achieved through the activation method 98Mo(n,γ)99Mo, utilizing a target of natural molybdenum trioxide irradiated under standard conditions (thermal neutron spectra and water environment). Under such conditions, the maximum specific activity of molybdenum-99 reaches (2.3
