The proposal made 50 years ago by Schulman (1968), Laidlaw & Morette-DeWitt (1971) and Dowker (1972) to decompose the propagator according homotopy classes of paths was a major breakthrough: it showed how Feynman functional integrals opened direct window on quantum properties topological origin in configuration space. This paper casts critical look at arguments brought this series papers its nu...

Good daylighting design in buildings not only provides a comfortable luminous environment, but also delivers energy savings and comfortable and healthy environments for building occupants. The importance of using daylight in educational buildings is because of the synchrony of operating hours of the school and daylight plenitude the sky. Daylight improves environmental quality and saves energy ...

  Introduction: Poor sensitivity and poor signal to noise ratio because of low injected thallium dose and presence of scattered photons are the main problems in using thallium in scintigraphic imaging of the heart. Scattered photons are the main cause of degrading the contrast and resolution in SPECT imaging that result in error in quantification. Thallium decay is ve...

Incorrect implementation of window parameters, such as configuration, position, and size, cause an unpleasant indoor environment. The authors reviewed performance in a hot humid climate this paper. Articles were screened detail to determine eligibility, compiled, organised according Preferred Reporting Items for Systematic Reviews Meta-Analyses (PRISMA) requirements. articles included review co...
