Children are sensitive to exposure of chemicals that may affect reproduction, cause allergies and cancer. Therefore it is important to strive for a toxin-free environment both at home and in preschools. The purpose of the study was to identify products in pre-school containing harmful chemicals. Furthermore, the purpose was to investigate how aware parents of the children in preschools are about chemicals in toys. The study included six preschools in Vindelns municipality and the parents of the children at these preschools. Inventories were made in the preschools to check which products could contain harmful chemicals and a questionnaire was distributed to the parents. The results of the inventories showed that most preschools have started removing plastic products but toys that can contain harmful substances still exist. The results of the surveys showed that 67% of parents do not know the concept of non-toxic preschool. This can be interpreted as the fact that the parents in question generally have limited knowledge about chemicals in toys and their impact on children's health. Parents need more information to become more aware of what products they have for their children and all the preschools in Vindelns municipality need to have a common plan to follow to continue to phase out products that may contain harmful substances in order to have a healthier environment for the children.

The study was designed to find a response on the behavioral level that would be an effective index across subjects for determining when conditioned aversive suppression of a response had been achieved. Ten male volunteers received shock during trials in which they had to smoke. Half of the subjects received a brief but more intense shock when they stopped smoking during a trial. A comparison of these subjects to the others showed their average amount of smoking suppression in pre- and post-treatment rates to be significantly (P < .025) greater. In addition, these subjects showed conditioned emotional responding. It was concluded that this behavioral level response was an effective index for determining when suppression of smoking would occur.

East Tennessee State University recently adopted Alma & Primo and was suprised by the lack of an A-Z database discovery module. Frustrated by having to maintain electronic resources separately on our library website and in Alma, we embarked on a goal to eliminate redundancy and use Alma/Primo exclusively. This presentation will cover our entire workflow in both Alma & Primo and the issues we encountered along the way. I'll first go over our process in Alma including MARC record creation, electronic collection setup, and the top level collection module. Next, I'll cover our workflow in Primo including normalization rules, scoping, PNX display, facets, and code table changes. The last section will cover the Primo X-Services API and how it was developed into an A-Z Database list.

This master's thesis deals with abrasive water jet cutting in the introduction. Another part is focused on deploying technology 3D cutting with abrasive water jet in conditions of a medium-sized company. This technology allows the elimination of bevels, and angel cutting. The following sections deal with technological capabilities of the specific machine and experimental comparison of samples cut by AWJ and DWJ technology. The work also includes a sample layout of machines on existing premises, the proposal for a potential component base and economic evaluation.

Braess' paradox is a counter-intuitive phenomenon which can occur in congesting networks. It refers to those cases where the introduction of a new link in the network results in the total travel time on the network increasing. The dissertation starts by introducing the traffic assignment problem and the concept of equilibrium in traffic assignment. The concept of equilibrium is based on Wardrop's first principle that all travellers will attempt to minimize their own travel time regardless of the effect on others. A literature review includes details of a number of papers that have been published investigating theoretical aspects of the paradox. There is also a brief description of Game Theory and the Nash Equilibrium. It has been shown that the equilibrium assignment is an example of Nash Equilibrium. The majority of work that has been published deals with networks where the delay functions that are used to compute the travel times on the links of the network do not include explicit representation of the capacity of the links. In this dissertation a network that is similar in form to the one first presented by Braess was constructed with the difference being that the well-known BPR function was used in the delay functions. This network was used to show that a number of findings that had been presented previously using simpler functions also applied to this network. It was shown that when it occurs, Braess' paradox only occurs over a range of values at relatively low levels of congestion. Real-world networks were then investigated and it was found that similar results occurred to those found in the simpler test networks that are often used in discussions of the paradox. Two methodologies of eliminating the paradox were investigated and the results are presented. / Decision Sciences / M.Sc.

The main topic of this work is the analysis of the measurement of partial discharge measurements on high voltage cables. The thesis also deals with other measurements, including the measurement of the loss factor and the voltage retention and breakdown test. Part of the text describes the issue of partial discharge, its measurement by galvanic method and methods of elimination of disturbing influences that affect this method in terms of sensitivity and accuracy of the measured values. Thesis also describes the construction of the cables, their marking and the tests carried out on them. There is also a description of the cable terminals used for measuring, especially water terminals, which are designed for high voltages and which are carried out in the practical part of the thesis. The next part deals with problems prior to the commissioning of water terminals and their preparation for certain tests, including description and evaluation of the results of the measurements.
