Container based calculation of greenhouse gas emissions. A method to determine emissions of container handlings in container terminals: Paper presented at 13th World Conference on Transport Research, WCTR 2013, July 15-18, 2013, Rio de Janeiro, Brazil
The container transport is the key factor for globalized markets. Due to this the shipping volume in the past 20 years grew by the factor of 5. Based on this, container terminals are very important transshipment facilities in global transport chains with a high amount of annual throughput and greenhouse gas (GHG) emissions. The transport sector is responsible for a large proportion of GHG emissions. An increase of traffic and GHG emissions for any transport mode is estimated. However, emissions are caused by transport modes and transshipment facilities and have to be reduced for both. State of the Art methods of determining transportation caused emissions consider only transportation modes. Emissions in transshipment facilities were currently rarely applied. However, for calculating emissions along the entire transport chain, the emissions from transshipment facilities have to be taken into account. Furthermore the reduction of greenhouse gases is significant for both the terminal itself and for the entire transport chain. Derived from existing standards for calculation of GHG emission a calculation tool for container terminals has been developed. Based on the energy consumption of the handling equipment and storage facilities the tool calculates the overall emissions in terminals. Furthermore, these emissions are allocated to loading units by using overall handling data and handling factors. The developed tool can be adapted to any multimodal container terminal. The calculated results of the tool include total emissions and the allocation of emissions on loading units
Initial tests of a new phantom for investigation of spatial resolution, partial volume effect and detectability in nuclear medicine tomography
Abstract in UndeterminedA new phantom has been designed that can provide simultaneously different target to background activity ratios with a linearly changing diameter of lesions. The purpose of the study was to describe and perform initial measurements with the phantom aimed to characterize different nuclear medicine tomographic systems and reconstruction algorithms in their performance and behaviour concerning partial volume effect (PVE) and detectability by varying the acquisition parameters and the count statistics. The phantom has an external vessel whose outline is half-cylindrical and allows it to be incorporated into an anthropomorphic thorax phantom. The phantom itself contains 16 fillable cones with an inner diameter linearly decreasing from 16 mm to 2 mm and a wall thickness of 1 mm acrylic glass. They as well as the outer vessel were separately filled with (99m)Tc-and (18)F-solutions respectively of different activity concentrations. The phantom was easy to fill and air bubbles could easily be avoided. Images taken using a SPECT/CT and a PET/CT system are presented as well as evaluations of PVE. The new phantom seems to be useful for comparison and optimisation of different acquisition and reconstruction parameters in nuclear medicine tomographic studies and for comparisons between various tomographic units
