and H‐MOR Catalysts
No full textA combined catalyst comprising TiO2-supported Re (Re(1)/TiO2; Re=1 wt\%) and H-MOR (SiO2/Al2O3=90) was found to promote the methylation of benzene using CO2 and H2. This catalytic system exhibited high performance with regard to the synthesis of methylated benzenes and gave high yields of total methylated products (up to 52 \% benzene-based yield and 42 \% CO2-based yield) under the reaction conditions employed in this study (pCO2=1 MPa; pH2=5 MPa; T=250 °C; t=20 h) in a batch reactor. Catalyst screening demonstrated that a combination of Re(1)/TiO2 and H-MOR (SiO2/Al2O3=90) exhibited superior performance compared to other combinations of supported metal catalysts and zeolites in terms of both yield and selectivity for methylated benzenes
Understanding Gender Equity in Author Order Assignment
No full textWomen remain underrepresented in many fields in computer science, particularly at higher levels. In academia, success and promotion are influenced by a researcher's publication record. In many fields, including computer science, multi-author papers are the norm. Evidence from other fields shows that author order norms can influence the assignment of credit. We conduct interviews of students and faculty in human-computer interaction (HCI) and machine learning (ML) to determine factors related to assignment of author order in collaborative publication. The outcomes of these interviews then informed metrics of interest for a bibliometric analysis of gender and collaboration in research papers published from 1996 to 2016 in three top HCI and ML conferences. Based on our findings, we make recommendations for assignment of credit in multi-author papers and interpretation of author order, particularly in regard to how this area affects women
Vehicle routing problems over time: a survey
No full textIn vehicle routing problems (VRPs) the decisions to be taken concern the assignment of customers to vehicles and the sequencing of the customers assigned to each vehicle. Additional decisions may need to be jointly taken, depending on the specific problem setting. In this paper, after discussing the different kinds of decisions taken in different classes of VRPs, the class where the decision about when the routes start from the depot has to be taken is considered and the related literature is reviewed. This class of problems, that we call VRPs over time, includes the periodic routing problems, the inventory routing problems, the vehicle routing problems with release dates, and the multi-trip vehicle routing problems
An investigation into the recent vegetation history of Great Wood, near Eggleston Co. Durham using fine resolution pollen analysis of Mor humus and relevant historical evidence.
No full textThis study investigated the recent vegetation history of an ancient woodland, Great Wood, near Eggleston Co. Durham which has been part of the lands of Eggleston Hall since at least 1614. Mor humus was extracted from two sites within the woodland canopy and consecutive 1cm samples were analysed from each sediment. The reasons for this fine resolution sampling was firstly, because the soil profiles were only between 14-20cms and only represented a time scale of a few hundred years, and secondly to provide fine temporal resolution to correspond with the fine spatial resolution obtainable under a closed canopy. Sediment analysis was undertaken to investigate the stratification of the soil in order to identify signs of disturbance. Mor # 1 proved to be highly stratified, whereas as mor # 2 was less stratified, possibly disturbed and had signs of charcoal at the lowest levels. It was therefore concluded that mor # 2 only represented part of the time scale that mor # 1 illustrated, as it was a more recently formed humus, the earlier part having been burnt away. An absolute time scale was not used but a relative time scale was assigned using documentary and anecdotal historical evidence. This took into account the development of the nearby village and the social and economic changes of the region, and also the association of the woodland with Eggleston Hall and the consequent utilisation of the woodland for timber and recreational purposes. The pollen record of mor # 1 was thought to represent the vegetation history from approximately 1750 to the present time, whereas the pollen record of mor # 2 shows the vegetation history from the late nineteenth century onwards. This time scale was deduced from the following:1. There were signs of a more open canopy, due to a greater proportion of herb pollen to tree pollen, and evidence of pollen representing a more regional source area such as Triticum and possibly Calluna. This was thought to represent 1750- 1820 when tillage increased in importance and there were reports of arable activity in the adjoining townfield probably causing a reduction in grazing pressure in the wood and allowing regeneration. This was promoted by the Enclosure Act in 1785, an attempt to establish mineral rights and to make the dales more commercially viable for agriculture and was a result of marginal land being used for tillage during the Napoleonic wars. However, signs of succession and canopy closure began to develop and there were also some signs of management deduced from Fagus pollen appearing and documentary evidence of the path construction through the woods.2. The herb pollen to tree pollen ratio began to fall and canopy closure continued but was not thought to be complete, due to selective management and extraction of timber. The disappearance of Triticum was believed to be due to a change in agricultural trends. Fagus pollen which was quite significant, disappeared abruptly due to the trees in the vicinity of the site being removed.3. Complete canopy closure shown by a consistently high tree pollen to herb pollen ratio with Quercus dominating, arose when management of the wood was abandoned in the 1920's.The fine resolution obtained, both temporally and spatially, demonstrated that mor humus was a useful medium for pollen analysis and with consideration of the underlying principles and mechanisms, meaningful interpretation of the pollen record was possible. Problems encountered with extraction of samples and during processing were discussed
La bellezza dell'anima come antidoto alla disumanizzazione. Le riscritture dei miti greci di Marie Luise Kaschnitz.
No full textIl saggio mette a fuoco come la riflessione sul tema della 'bellezza dell'anima' attraverso le riscritture di alcuni miti greci abbia rappresentato per la scrittrice tedesca M. L. Kaschnitz una forma di resistenza intellettuale alla barbarie e alla disumanizzazione nazista e possa essere considerata come una delle pagine più significative della "innere Emigration"

Benchmarking database for Unibest-TC and Delft3D-MOR
No full textA benchmarking database for UNIBEST-TC and Delft3D-MOR has been implemented with the objective to facilitate testing of various model settings. The database (Chapter 2) has been sub-divided into separate datasets, in which a number of cases are defined. This structure implies that running a simple script file in a case directory automatically runs the model and produces plots that compare the model output with available measurements at predefined moments and places. The clear database structure allows a user to straightforwardly insert a new dataset. Up to now, 11 data sets have been implemented for UNIBEST-TC, as described in Chapter 3 and 4. The data sets include both laboratory and field measurements. The majority of the datasets have been selected for their applicability to enable the testing of various hydrodynamic physical processes, such as wave height, and cross-shore and longshore velocity. Various other also include sediment transport information and profile development. Besides comparison of model results and experiments, the benchmarking database facilitates statistical error analysis, of which various examples are shown in Chapter 5. The benchmarking database for Delft3D-MOR is described in Chapter 6. A list of conclusions and recommendations is given in Chapter 7
