A vehicle with a self-contained cooling and heating capability and a tenting feature for sheltering and controlling the temperature at a given location. Thus, the present invention provides novel substituted piperidino phenyloxazolidinone derivatives, processes for making compounds as well as antimicrobial compositions containing said derivatives as active ingredients and methods of treating bacterial infections with the said derivatives. Two insertion trenches are oppositely formed on both sides of the fixing base for holding the slide base. Resulting object code also allows processors lacking a suitable memory management processor to skip the reference table, preserving upward compatibility. The selector circuitry provides one of the two inputs of the logic element as an output in response to a selection signal.
