Viral meningitis: Meningitis caused by many viruses is usually contagious. However, certain viruses that are transmitted by mosquitoes are usually not spread person to person, so they are not contagious.
3] Heat transfers through the glass by conduction 4] Heat transfers from the glass to the outside air via convection. If the temperature differences are small and there are no winds or drafts, transfer of heat to/from air/glass will be by conduction.
Given that the heat transfer through the wall system is typically represented by an overall R-value for the opaque area ( which may be area-weighted to include framing components ) , and the thermal transmittance of the window system is represented by a U-factor for the entire window area , the flanking heat flow around the base of the thinner ...
