Engineering Study for Reducing Sign Vandalism Final Report Highway Research Advisory Board Projec HR 246, June 1992

Sign vandalism has traditionally been a vexing problem for Iowa counties. The extent of the cost and incidence of these acts have never been fully ascertained, but a 1990 survey indicated that they cost Iowa counties more than 1.5 million dollars annually. In 1990, the Iowa Legislature recognized the seriousness of the problem and strengthened the existing sign vandalism law by increasing the penalty for illegal possession of a traffic control device from a simple to a serious misdemeanor. However, the courts must be willing to prosecute vandals to the magnitude provided in the Iowa Code. An educational campaign begun in 1987 involving over 200 Iowa school districts to educate students on the seriousness of the problem evidently did not have the effect of dramatically reducing the overall cost of sign vandalism in Iowa. This study sought to define the scope of the problem and possibly offer some effective countermeasures to combat sign vandalism and theft in Iowa.

Pese a que ya en algunos trabajos de fines del siglo XIX se cita la existencia de materiales arqueológicos en el Puig de Sant Andreu (Ullastret), y al hecho de que a instancia del Institut d'Estudis Catalans el enclave fuese incluido en el Registre del Patrimoni Historie, Artístie i Arqueologie de Catalunya l'any 1936 (DOGC de 08/07/1936), no fue hasta 1947 en que Miquel Oliva, animado por el Dr. Lluís Pericot, Comisario Provincial de Excavaciones en Gerona, inició las intervenciones sistemáticas en el yacimiento, realizando una labor ininterrumpida hasta su fallecimiento en 1974.

Aspectes econòmics de l'evolució del sistema públic d'ensenyament superior a Catalunya, 1985-1992

L'educació superior espanyola ha sofert un procés d'expansió generalitzat a partir de la segona meitat de la decada deis vuitanta. Malgrat aixo, aquesta expansió no pot ser analitzada conjuntament, ates que durant el mateix període es fan efectives les transferencies de competencies en materia d'educació a set comunitats autonomes que comencen a dur a terme polítiques universitaries no sempre concurrents. En aquest article abordarem el model catala d'expansió úniversitaria i el seu finançament, fent emfasi en els problemes derivats dé l'expansió i les seves possibles solucions. Per fer-ho, utilitzarem la següent estructura: en primer lloc, en l'apartat 2 es descriuen els elements basics del procés d'expansió (especialment la creació de les cinc noves universitats) i la situació resultant tal i com es presenta en l'actualitat. Sense aquestes descripcibns no cobrarien sentit les analisis més específiques sobre el finançament, que es presenten en els apartats 3 i 4.

¿El modelo de cuña compuesta de C.I. Migliorini (1948) es aplicable a la estructura del rector central de los Catalánides?

Se comentan las conclusiones sobre la estructura de dos Catalánides recientemente publicadas, resaltando la ausencia de datos concretos que permitan aplicar el modelo de la cuna compuesta de Migliorini para 1os Catalánides. Además, los datos publicados (previamente, más como nuestras observaciones personales, indican una clara separación en el tiempo de una fase de comprensión y otra de distensión posterior.

One-year prevalence of low back pain in two Swiss regions: estimates from the population participating in the 1992-1993 MONICA project.

STUDY DESIGN: A cross-sectional survey was performed. OBJECTIVE: To estimate the extent of low back pain as a public health problem. SUMMARY OF BACKGROUND DATA: Health surveys converge on very high estimates of low back pain in general populations, but few studies have included severity criteria in their definition and conclusions. Because it is unlikely that interventions will influence the prevalence of minimal and infrequent symptoms, greater attention should be paid to characteristics of low back pain that indicate some impact on the life of survey respondents. METHODS: Two regions participated in the MONICA (MONitoring of trends and determinants in CArdiovascular disease) project in Switzerland. Participants randomly selected from the general population completed a standard self-administered questionnaire on cardiovascular risk factors. A special section on low back pain was added in the third (1992-1993) MONICA survey and completed by 3227 participants. RESULTS: A regional difference found in the 12-month prevalence rate disappeared with the inclusion of severity criteria. Low back pain over more than seven cumulated days was reported among men by 20.2% (age range, 25-34 years) to 28.5% (age range, 65-74 years), respectively, among women by 31.1% to 38.5%. Similar rates of reduction in activity (professional, housekeeping, and leisure time) and medical consultation (conventional and nonconventional) motivated by low back pain characterized the two participating regions. The cumulative duration of pain was related to all the indicators showing the impact of low back pain on everyday life. CONCLUSIONS: Determining the cumulative duration of low back pain over the preceding year is a straightforward task, and a cutoff at 1 week seems appropriate for distinguishing between low- and high-impact low back pain.

Effects of Heat Straightening Structural Steel, MLR-91-3, 1992

Heat straightening of steel beams on bridges struck by over height trucks has become common practice in recent years in Iowa. A study of the effects of this heat straightening on the steel beams thus straightened is needed. Appropriate samples for mechanical and metallurgical tests were cut from the same rolled beam from the end which was heated and the end which was not heated and the test results were compared. The test results showed beyond doubt that the steel was being heated beyond the permitted temperature and that the impact properties are being drastically reduced by the current method of heat straightening.

Control of Concrete Deterioration Due to Trace Compounds in Deicers, HR-299, 1992

This report describes the research completed under the research contract entitled "Development of a Conductometric Test for Frost Resistance of Concrete" undertaken for the Iowa Highway Research Board. The objective of the project was to develop a test method which can be reasonably and rapidly performed in the laboratory and in the field to predict, with a high degree of certainty, the behavior of concrete subjected to the action of alternate freezing and thawing. The significance of the results obtained, and recommendations for use and the continued development of conductometric testing are presented in this final report. In this project the conductometric evaluation of concrete durability was explored with three different test methods. The test methods and procedures for each type of test as well as presentation of the results obtained and their significance are included in the body of the report. The three test methods were: (1) Conductometric evaluation of the resistance of concrete to rapid freezing and thawing, (2) Conductometric evaluation of the resistance of concrete to natural freezing and thawing, and (3) Conductometric evaluation of the pore size distribution of concrete and its correlation to concrete durability. The report also includes recommendations for the continued development of these test methods.

Evaluation of Asphalt Mix Permeability, MLR-90-2, 1992

Efforts to eliminate rutting on the Interstate system have resulted in 3/4 in. aggregate mixes, with 75 blow Marshall, 85% crushed aggregate mix designs. On a few of these projects paved in 1988-1989, water has appeared on the surfaces. Some conclusions have been reached by visual on-sight investigations that the water is coming from surface water, rain and melting snow gaining entry into the surface asphalt mixture, then coming back out in selected areas. Cores were taken from several Interstate projects and tested for permeability to investigate the surface water theory that supposedly happens with only the 3/4 in. mixtures. All cores were of asphalt overlays over portland cement concrete, except for the Clarke County project which is full depth AC. The testing consisted of densities, permeabilities, voids by high pressure airmeter (HPAM), extraction, gradations, AC content, and film thicknesses. Resilient modulus, indirect tensile and retained strengths after freeze/thaw were also done. All of the test results are about as expected. Permeabilities, the main reason for testing, ranged from 0.00 to 2.67 ft per day and averages less than 1/2 ft per day if the following two tests are disregarded. One test on each binder course came out to 15.24 ft/day, and a surface course at 13.78 ft/day but these are not out of supposedly problem projects.
