Paleosols contain information about the rates of soil organic carbon turnover when the soil was actively forming. However, this temporal information is often difficult to interpret without tight stratigraphic control on the age of the paleosol. Here we apply ramped pyrolysis/oxidation (Ramped PyrOx) C-14 analyses to evaluate age spectra of transgressive early Holocene paleosols from the Mississippi Delta in southeastern Louisiana, USA. We find C-14 age spectra from soil organic matter (SOM) in both paleosols and overlying basal peats that represent variability in age that is close to, or only slightly greater than, analytical uncertainty of C-14 measurements, despite different sources of carbon with likely disparate ages. Such age spectra have not previously been observed in the sedimentary record. Here they indicate vigorous soil carbon turnover prior to burial, which homogenized C-14 ages within SOM across the entire thermochemical spectrum. The weighted bulk C-14 ages from Ramped PyrOx of paleosols and overlying peats are identical within analytical and process-associated uncertainty, and corroborate C-14 ages from charcoal fragments and plant macrofossils from the overlying peat. The youngest ages from Ramped PyrOx age spectra may also potentially be applied as chronometers for stratigraphic burial ages. Our results suggest rapid turnover (<<300 years) of carbon in these soils relative to input of allochthonous carbon, indicating that the C-14 age of different soil components is decoupled from thermochemical stability and instead reflects vigorous turnover processes. The concurrence of paleosol and peat C-14 ages also suggests that pedogenic processes were linked with the development of coastal marshes, and that the priming effect potentially masked the signal of allochthonous carbon inputs during sea level rise.

Context. With the proportional increase in the population of elderly people, there is an increase in the need for providing quality health-care. Operating room planning is one aspect that is considered to meet the requirement of providing quality health care. Operatingroom planning concerns about the efficient management of the available resources to perform surgeries. It deals with allocation and assignment of surgeries to operating rooms in a sequential manner using resource optimization strategies to manage with the available operating rooms. Objectives. In this thesis, we investigate the behavior and applicabilityof an optimization model and measure the degree to which the model can efficiently utilize the available hospital resources. Methods. Simulations are conducted to test the impact of implemented model on turnover time. The experiment is conducted on three different scenarios using the real world data collected from Blekinge hospital. Results. The impact on the turnover time measured for the three different scenarios is evaluated using simulation experiment. The relationship between the scenarios is identified by comparing the results with a baseline scenario (real world schedule). Conclusions. Based on the analysis, we conclude that the new optimization model is capable of scheduling better than the existing scheduling system used by the hospitals. The observations show that optimization model significantly reduces the turnover time compared to the real schedule. Besides, the scenario using an additional resourceis found to have better performance compared to other scenarios. The thesis concludes by showcasing the performance and applicability of the optimization model.

The diploma thesis titled "Analysis of receivables management in Rostex Vyškov, s. r. o." deals with claims from legal, accounting and tax point of view in its theoretical part. It describes the receivables management process, the risk influence and the importance of preventive measures against the problem claims occurrence. It also deals with debt collection and analyzes the impact of late payments and bad debts on the economic activities. Conclusion of the theoretical part is focused on out-of-court and judicial methods of debt collection. The practical part analyzes the receivables management in Rostex Vyškov, s. r. o. After a brief financial assessment of the company, it focuses primarily on claims records, supplier selection and control. Accounts receivables turnover time and payback period in the Czech Republic and Europe are confronted too. Finally, possible main reasons for the occurrence of outstanding claims are discussed together with the most common tools of credit management in the Czech Republic, in comparison with Europe again.

<p>The focus of this thesis is on groundwater vulnerability assessment by process-based simulation models and data acquisition for these assessments. A modelling system for intrinsic groundwater vulnerability assessment in water supply areas was developed, consisting of flow- and transport models for the unsaturated zone and the groundwater zone, coupled to a geographical informa-tion system. The system was applied to a water supply area located close to a major road south of Stockholm. Chloride was used as an indicator in determining the vulnerability for groundwater contamination from the road. The approach was useful to illustrate the dynamic change of chlo-ride concentrations both during the stage of continuous application and after the applications was terminated. A structure and content of a database for flow and transport modelling, based on hydrogeological environments, was outlined. An existing hydrogeological parameter database, HPAR at the Geological Survey of Sweden (SGU), was examined as a potential source of data for the new database. Values for some important parameters needed for groundwater modelling, such as hydraulic conductivity and effective porosity, were lacking in the three municipal HPAR databases that were studied. It was suggested that these data should be added, together with information on the hydrogeological environments, for all geographical positions of interest. Without such minimum information, the efficient use of modelling tools could not be expected.</p><p>Typical profiles of three common Swedish hydrogeological environments (sand deposits, glacial till and clay covered areas) were used to represent generic input data to model simulations in the unsaturated zone so that the importance of soil, vegetation type and groundwater levels on turn-over times of conservative contaminants transported by natural recharge could be examined. The same profiles were used to predict the penetration depth of accidental liquid spills that occur at the land surface level. In the case of contaminant transport by natural recharge, water storage in the soil profile and vegetation type played an important role for turnover times. For liquid spills, the hydraulic con-ductivity was found to be of major importance, while the water retention properties were of less importance. Modelling, together with available data sources, were successfully used to demon-strate the vulnerability of different environmental conditions.</p>
