Recovery time and propagation effects of passenger transport disruptions
No full textWe propose a method to evaluate public transport network vulnerability. We study the evolution of the passenger Volume Over Capacity (VOC) ratio throughout the network to measure the spatial and temporal extent of the impacts caused by an unplanned service segment disruption. The VOC ratio provides an indication of the on-board travel comfort, an important level-of-service indicator, as well as reflects the residual capacity for absorbing additional demand. Because of the dynamic nature of public transport systems, disturbances propagate through the network in both time and space. Our modelling approach is able to capture transit system dynamics and quantify the extent to which the network exhibits spillover effects. We apply the method to the case of the rapid public transport system of Stockholm Sweden We demonstrate how the changes in network saturation and the corresponding recovery time can be quantified.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Transport and Plannin
Earlinet validation of CATS L2 product
No full textThe Cloud-Aerosol Transport System (CATS) onboard the International Space Station (ISS), is a lidar system providing vertically resolved aerosol and cloud profiles since February 2015. In this study, the CATS aerosol product is validated against the aerosol profiles provided by the European Aerosol Research Lidar Network (EARLINET). This validation activity is based on collocated CATS-EARLINET measurements and the comparison of the particle backscatter coefficient at 1064nm.Atmospheric Remote Sensin
Preliminary Studies on the Intrahepatic Anatomy of the Venous Vasculature in Cats
No full textHepatic surgeries are often performed in cats to obtain a disease diagnosis, for the removal of masses, or for the treatment of shunts. Whereas the vascular anatomy of the liver has been studied in dogs, such evidence is lacking in cats. The current study used corrosion casts of portal and hepatic veins and computed tomography (CT) analysis of the casts to identify and describe the intrahepatic anatomy in healthy cat livers (n = 7). The results showed that feline livers had a consistent intrahepatic portal and venous anatomy, with only minor disparities in the numbers of secondary and tertiary branches. The feline portal vein consistently divided into two major branches and not three, as previously described in the literature for cats. The finding of a portal vein originating from the right medial lobe branch leading to the quadrate lobe in 4/7 specimens is a novelty of the feline anatomy that was not previously described in dogs. Partial to complete fusion of the caudate process of the caudate and the right lateral lobe, with a lack of clear venous separation between the lobes, was present in two specimens. These findings allowed a detailed description of the most common intrahepatic venous patterns in cats. Further anatomical studies should be encouraged to confirm the present findings and to investigate the utility of this information in surgical settings
Preliminary investigation of the effects of long-term dietary intake of genistein and daidzein on hepatic histopathology and biochemistry in domestic cats (Felis catus)
No full textDietary isoflavones have been hypothesised to play a role in hepatic veno-occlusive disease in captive exotic felids, although empirical evidence is lacking. This study aimed to investigate the effect of long-term (>1 year) dietary genistein and daidzein exposure on the hepatic biochemistry and histology of domestic cats. Individual cats were assessed for hepatic enzyme and bile acid production before and after the removal of isoflavones from their diet in the treatment group (n=4), and at the same times in unexposed control animals (n=7). No significant differences were detectable in hepatic biochemistry between treatment and control groups, and all serum values were within the normal reference ranges for domestic cats. Additionally, treatment animals demonstrated slightly greater areas of fibrosis surrounding hepatic venules than control animals, but this difference was not statistically significant. On the basis of the results presented, dietary isoflavones, at the current dose and duration of exposure do not appear to modulate hepatic enzyme production or histological parameters
Urinary iodide concentration in hyperthyroid cats
No full textObjective—To compare concentrations of urinary iodide (UI) in euthyroid and untreated hyperthyroid cats.
Animals—118 euthyroid and 88 hyperthyroid client-owned cats from 2 nonreferral veterinary practices.
Procedures—Iodide concentration was measured in 5 urine samples collected every 3 to 12 months from selected cats, and variability of results between euthyroid cats and hyperthyroid cats prior to the diagnosis of hyperthyroidism was evaluated via 1-way ANOVA, after logarithmic transformation of UI concentrations (logUIs). The UI concentration in hyperthyroid cats was measured at diagnosis and 2 to 6 weeks and 3 to 6 months after treatment for hyperthyroidism. The pretreatment logUI in hyperthyroid cats was compared with that in euthyroid cats, taking into account the effects of renal function on UI concentration. Iodine intake was estimated in euthyroid cats following calculation of the volume of daily urine output, with a fixed value for iodine concentration in feces.
Results—The variability of UI concentrations did not differ significantly between hyperthyroid (n = 10) and euthyroid (8) cats. The logUI increased 2 to 6 weeks after initiation of treatment in hyperthyroid cats (n = 80) and was lower in azotemic versus nonazotemic cats. Hyperthyroid cats had a lower logUI than euthyroid cats, and there was no evidence of deficient iodine intake in euthyroid cats.
Conclusions and Clinical Relevance—The logUI was lower in cats with azotemia and with untreated hyperthyroidism, compared with that in euthyroid cats from the same population. Additional studies are needed to determine whether iodine intake plays a role in the development of hyperthyroidism in cats.Peer reviewedFinal article publishe
How can we better plan for the unplanned? Designing and operating more robust public transport systems
No full textTraditionally, transport systems have been designed to perform well under normal conditions assuming that everything works as planned. As anyone that uses public transport can testify, deviations from planning are a recurrent phenomenon. Investments in public transport are therefore increasingly motivated by the need to improve their reliability and robustness to disturbances and disruptions. Public transport systems are especially vulnerable to disruptions due to their lower density, the rigidity of service planning and operational constraints. In a series of studies, Assistant Professor Oded Cats investigates how public transport systems can be planned and operated to better withstand unplanned conditions.Transport & PlanningCivil Engineering and Geoscience
Thoracic injuries in cats with traumatic fractures
No full textThe medical records of 93 cats with traumatic fractures were examined to study the pattern of thoracic trauma and establish a possible relationship between specific patterns of skeletal trauma and the prevalence of thoracic wall and pulmonary injury. Radiographic evidence of thoracic trauma was identified in 38.7% of these cats. Cats with fractures cranial to T13 were significantly more likely to sustain thoracic trauma (58%) compared to those suffering a fracture caudal to LI (25%). Cats involved in motor vehicle accident were more likely to have radiographic evidence of thoracic trauma (52%) compared to those injured by other means (22%). Forty percent of cats with radio-graphic evidence of thoracic injury did not show any clinical sign.
In a retrospective survey of 93 cats admitted for evaluation of traumatic fractures, 36 cats (38.7%) had radiographic evidence of thoracic trauma. The most common thoracic injuries were lung contusion (66.6%) and pneumothorax (36%). Forty percent of the cats, with radiographic abnormalities, did not show clinical signs suggestive of thoracic injury
