Abstract: A control valve a body having a fluid inlet and a fluid outlet and a valve seat between the fluid inlet and the fluid outlet. A valve plug is positioned within the body and movable between a closed position, in which the valve plug sealingly engages the valve seat, and an open position, in which the valve plug is spaced away from the valve seat. A cage is disposed within the body adjacent the valve seat. The cage includes a cage wall having a throttling inlet and a throttling outlet, which are connected by a throttling passageway. The throttling passageway has a radial direction, an axial direction, and an angular direction between the throttling inlet and the throttling outlet. The passageway includes a plurality of vena contracta and a plurality of pressure recovery chambers, which form a plurality of pressure reducing stages.

Abstract: A recombinant or chemically synthesized polypeptide includes SEQ ID NO: 1 or a variant thereof. A diagnostically useful carrier includes means for specifically capturing an antibody to SEQ ID NO: 1 in a sample from a subject. A kit includes the polypeptide or the diagnostically useful carrier. A method for diagnosing, prognosing, or monitoring the treatment of a virus, preferably Flavivirus, more preferably POWV infection includes detecting in the sample from a subject the presence or absence of an antibody to SEQ ID NO: 1 and/or an antibody to SEQ ID NO: 2. A polypeptide including SEQ ID NO: 1 and/or SEQ ID NO: 2, and/or a variant thereof is useful for the diagnosis. An IgM antibody to SEQ ID NO: 1 or means for specifically capturing an IgM class antibody to SEQ ID NO: 1 is useful for increasing the diagnostic reliability of an immunoassay for the diagnosis of a virus infection.

A diagnostically useful carrier includes means for specifically capturing an antibody to SEQ ID NO: 1 in a sample from a subject. A kit includes the polypeptide or the diagnostically useful carrier. A method for diagnosing, proposing, or monitoring the treatment of a virus, preferably Flavivirus, more preferably POWV infection includes detecting in the sample from a subject the presence or absence of an antibody to SEQ ID NO: 1 and/or an antibody to SEQ ID NO: 2. A polypeptide including SEQ NO: 1 and/or SEQ ID NO: 2, and/or a variant thereof is useful for the diagnosis. An IgIVI antibody to SEQ ID NO: 1 or means for specifically capturing an IgM class antibody to SEQ ID NO: 1 is useful for increasing the diagnostic reliability of an immunoassay for the diagnosis of a virus infection.
