Atalie Van Dam Oral History Interview
No full textAtalie Cook Van Dam discusses her experiences growing up in Price, Utah, and her observations since moving back after many years. She highlights the positive community support and opportunities provided by USU Eastern\u27s growth, but expresses sadness over the decline of downtown Price and the impact of the coal mining industry\u27s slowdown. Van Dam also shares the challenges of rural life, such as limited job opportunities and the pervasive "talk of the town," contrasting it with a surprising feeling of less safety in Price compared to urban areas. Despite these concerns, she values the strong community connections and hopes for sustainable economic development and a renewed sense of civic pride in Price\u27s future

Tiny Perceptions
No full textA slightly rough texture, a minor vibration, a change in intensity of temperature or color. Within our daily experience as well as within the design process tiny perceptions guide our way. They are the ‘difference that makes a difference’. With a focus on these ‘Tiny Perceptions’ Renske Maria van Dam and the students of the Rietveld Academy in Amsterdam presented ‘It’s going to rain soon’: a spatial-temporal exhibition in which the sun and the wind perform.status: Publishe
Te vroeg rooien niet altijd wenselijk (verslag van M. van Dam op actualiteitenavond CNB/KAVB)
No full textTijdens de CNB/KAVB actualiteitenavond in Creil ging PPO-onderzoeker Martin van Dam dieper in op de resultaten van zijn onderzoek naar effecten op groei en bloei van vroeg gerooide tulpen. Daarbij ging het hem met name om de effecten op broeikwaliteit en op de wortelgroei van plantgoed
A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
Introduction. Europe 2020: Towards a more social EU?
No full textThis contribution aims to introduce the overall architecture of the new EU socio-economic governance and explain the complex interplay between its different parts: the three priorities, the five EU headline targets which need to be translated into national targets, the seven flagship initiatives, the ten Integrated Guidelines for employment and economic policies, and the newly introduced concept of a “European semester” that should contribute to mobilising the different instruments in support of the new Strategy and
to aligning it with the Stability and Growth Pact
Verzuring van vennen : een tijdsverschijnsel
No full textChanges in chemistry, particularly pH, of a number of soft-water moorland pools in The Netherlands are described. Several groups of organisms, including diatoms, and direct measurements are used to infer past pH values. Diatoms were studied from preserved samples from the beginning of the 20th century, from recent samples and from sediment cores. Old data about chemistry, macrophytes and human impact were obtained from published and unpublished documents.In isolated pools in nature reserves the pH declined to c. 4 from initial values between 4 and 6 at the beginning of this century. Small inputs of nutrients by agriculture, fisheries or swimming retards acidification. The diversity and dissimilarity of diatom assemblages decrease by acidification, particularly in clear water pools. Acidification boosts the growth of the diatom Eunotiaexigua .Sulphate concentrations were extremely high in 1977 and 1978 in two clear water pools where more than half of the bottom surface was exposed to the atmosphere during the extremely dry summer of 1976 and decreased afterwards, parallel to Juncusbulbosus . E.exigua decreased with a delay. Apparently reduced sulphur compounds, which accumulated in the bottom due to atmospheric deposition in the decades before, were oxidized in the dry summer of 1976. No such changes were seen after the dry summer of 1921. In these two pools the pH declined from 5-6 in 1920 to c. 4 in c. 1980. In a brown water pool, where only a small fraction of the bottom was exposed in 1976, changes by the drought were small. Also the decline of pH in this pool since 1920 (c. 0.5 unit) was relatively small.Palaeolimnological studies were conducted in three pools, which were supposed to be pristine. However, it appeared both from coring results and documented evidence that these pools had pH values between 4 and 5 in the early 19th century and became subsequently more alkaline by nutrient enrichment. After 1900 the pools were acidified because anthropogenic enrichment was finished and acid atmospheric deposition increased.To follow the effect of future changes of acid atmospheric deposition and understand the processes involved, chemical and biological monitoring should continue. Input of buffering substances in some moorland pools could maintain weakly acid conditions in Dutch surface waters.</p
Modelling studies of fish production in integrated agriculture - aquaculture systems
No full textThe general objective of this thesis is to formulate a general model for fish production in integrated ponds and ricefields as a means of obtaining a better understanding of these production systems. Integrated culture systems produce fish without large industrial energy inputs and have positive effects on the whole farm system. A main characteristic is their environmental variability, notably dissolved oxygen concentration and temperature. A systems approach using mathematical models is advocated because it can lead to insights that have universal applicability while avoiding the pitfalls of site- and species-specific, expensive experimental work. Two modelling approaches are distinguished: descriptive models, generally the result of statistical analysis of datasets; and explanatory models, based on knowledge of the biological processes underlying fish production.Multiple regression analysis (a descriptive modelling technique) was used for the analysis of data from 15 integrated rice-fish production experiments with the Nile tilapia (Oreochromis niloticus L.) in the Philippines. Results showed that this technique led to insights that had not been obtained through separate analysis of the experiments. Main drawback of this method was that the models were not applicable to other production environments.An explanatory model (called Fish Growth Simulator, or FGS) for growth of O.niloticus was developed on the basis of an existing simulation model for the African catfish Clarias gariepinus Burchell (1822). After parameterization and calibration, the model gave good predictions of fish growth in independent datasets. Parameterization and calibration of the same model for the rainbow trout Onchorhynchus mykiss (Walbaum) demonstrated the generality of the model and it was concluded that, provided that enough data are available, the model may be used to predict growth in a wide range of fish species. Food amount and composition, and temperature were the environmental variables upon which the model based its predictions.FGS was expanded with a dissolved oxygen module to accomodate oxygen as an environmental variable. The module was based on the hypothesis that oxygen is needed in sufficient amounts for aerobic metabolism, and that gill surface area limits the supply of oxygen to fish. The resulting model allowed the simulation of fish growth under low dissolved oxygen concentration and also provided an explanation for differences in the final weight of fishes, both within and between species.FGS was used for simulation of food and oxygen limitations in waste-fed fish ponds in Honduras, Thailand and Rwanda. The model simulated fish growth for various combinations of environmental conditions: temperature, food availability and dissolved oxygen concentration. Validation, using data from Indonesia and Panama, was not successful because estimates of the food consumption rate in these countries were not reliable.In the last chapter methodology, the role of oxygen in fish metabolism and growth, model implications for the management of integrated agriculture-aquaculture systems and implications for further work are discussed
