Microautoradiographs of the harley leaf immediately after spraying showed the radioactive substance on the epidermis (Figure 6). However, a sequential time series of microautoradiographs of cryostat leaf sections (8 ym) shows that triadimefon and/or its metabolites are rapidly taken up (Figure 7). Subsequent transport takes place almost exclusively with the transpiration flow in the xylem. This transport system is then rapidly abandoned again so the active substance and/or metabolites move out of the transportation stream and are found in all leaf cells (29). 

In general, the overall balance for the mass transport streams (Eqs. 6.23 and 6.24) at the column inlet and outlet has to be fulfilled. In Eq. 6.92 the closed boundary condition is obtained by setting the dispersion coefficient outside the column equal to zero. In open systems, the column stretches to infinity and in these limits concentration changes are zero. 

Briggs, Bromilow and Evans subsequently examined the transportation stream concentration factor (TSFC) which is the concentration in the xylem divided by the concentration in the external solution. They developed Equation 2 for barley.

It is possible to circumvent problems arising from quercetin s apparent immobility when added to the basal end of a transport segment, by applying it or N PA as small local doses half-way up 20 mm long hypocotyl segments (Table 4). With this method both substances can be seen to interrupt the lAA transport stream and to inhibit basipetal auxin transport. Attempts to demonstrate perturbation of seedling gravitropism by quercetin have so far been unsuccessful. 

The transport subsystem employs the fixed-length transport stream packetization approach defined in ISO/IEC13818-1 [12], which is usually referred to as the MPEG-2 systems standard. This approach is well-suited to the needs of terrestrial broadcast and cable television transmission of digital television. The use of relatively short, fixed-length packets matches weU with the needs and techniques for error protection in both terrestrial broadcast and cable television distribution environments. 

The system time table is a small data structure that fits in one transport stream packet and serves as a reference for time-of-day functions. Receivers can use this table to manage various operations and scheduled events, as well as display time-of-day. 

There are up to 128 event information tables, EIT-0 through EIT-127, each of which describes the events or television programs for a time interval of 3 h. Because the maximum number of EITs is 128, up to 16 days of programming may be advertised in advance. At minimum, the first four EITs must always be present in every transport stream, and 24 are recommended. Each EIT-k may have multiple instances, one for each virtual channel in the VCT. 

Transport stream identification (TSID). The preassigned TSIDs must be set correctly in all three locations (PAT, VCT common information, and virtual channel-specific information). 

Payload Payload refers to the bytes that foUow the header byte in a packet. The transport stream packet header and adaptation fields are not payload. 

Program clock reference (PCR) A time stamp in the transport stream from which decoder timing is derived. 

Program specific information (PSl) Normative data that are necessary for the demultiplexing of transport streams and the successful regeneration of programs. 

Interval triggering lets the operator quickly check for intervals narrower than expected or wider than expected. Typical apphcations include monitoring for transmission phase changes in the output of a modem or for signal dropouts, such as missing bits in a transport stream. 

The rotating ring-disk electrode was first proposed by Frumkin et al in 1959 [24], This system can be used two different potentials, causing a reaction in the central electrode and then another subsequent reaction at the forward ring electrode, as the transport stream shown above. The proposed modem adaptation from Fmmkin for analysis is illustrated in Figure 8.
