A test system has been developed that allows the formation of mass balances for 14C-labeled organic compounds in soil-plant-atmosphere systems under field conditions. The main focus was the quantification of all different 14C-labeled gaseous losses from soil and plant surfaces after the application of 14C-labeled chemicals; therefore, a two-chamber system(More)
Resource reservation in advance (ReRA) enables scheduling and allocation of resources at an early stage in time. This way, the availability of resources can actually be guaranteed for the point in time when the resources are needed. As opposed to that, current reservation protocols such as RSVP perform an "immediate" reservation without advance scheduling.(More)
Existing reservation protocols such as RSVP implement so-called immediate reservations (ImRe) that are requested and granted just when the resources are actually needed. This paper describes the design, implementation and evaluation of a novel advance reservation protocol. Its major property is that resources are reserved well in advance to the actual usage(More)
The major detoxification product in maize roots after 24 h benzoxazolin-2(3H)-one (BOA) exposure was identified as glucoside carbamate resulting from rearrangement of BOA-N-glucoside, but the pathway of N-glucosylation, enzymes involved and the site of synthesis were previously unknown. Assaying whole cell proteins revealed the necessity of H2O2 and Fe(2+)(More)
This paper describes recent experiences with evaluating and implementing advanced communication protocols on top of ATM. First, experiences and performance results with conventional TCP/IP over ATM based on Digital Equipment’s Gigaswitch/ATM are reported. Moreover, the behaviour and performance of application-level remote procedure call protocols with mass(More)
This paper describes recent experiences with evaluating and implementing advanced internetwork communication protocols on top of ATM. First, performance results with conventional TCP/IP over ATM based on Digital Equipment’s Gigaswitch /ATM are reported. It becomes obvious that current protocols must be tuned specifically in order to exploit ATM performance.(More)
Diese Dissertation entstand im Rahmen eines DFG-Projektes an der TU-Dresden. Ausgehend von der allgemeinen Zielsetzung des Projektes, die eine komplexe Betrachtung der Thematik “Vorabreservierungen in verteilten Systemen” darstellt, werden zunächst grundlegende gemeinschaftliche Schwerpunktthemen dargestellt und diskutiert. Darauf aufbauend befaßt sich(More)
