Evaluation des campagnes de prévention contre le SIDA en Suisse : Kantonale Strategien der AIDS-Prävention und -Bekämpfung : Schlussbericht 1988

Der vorliegende Bericht versucht, zusammenfassend den Fortgang der Präventionsarbeit in ausgewählten Kantonen bis November 1988 nachzuvollziehen und nach bestimmten Kriterien analytisch zu beurteilen. Die Studie lehnt sich an die von 1987, "Kantonale Aktivitäten der AIDS-Prävention", an. Es wird bei dieser Untersuchung aber nicht darum gehen, einen Katalog der Massnahmen, welche in den ausgewählten Kantonen getrooffen wurden, zu erstellen. Vielmehr wird der Prozess, der sich auf kantonaler Ebene im Bereich der Aidsprophylaxe abspielt, im Mittelpunkt der Aufmerksamkeit stehen. Im Verlaufe der Etablierung und Institutionalisierung der AIDS-Prävention werden auf Konzepte und Strategien entwickelt, die aufeinander abgestimmt werden müssen. Dem Zusammenspiel zwischen den verschiedenen, an der AIDS-Prävention und -Bekämpfung beteiligten Akteuren und der Koordination ihrer je einzelnen Konzepte und Strategien wird deshalb besondere Aufmerksamkeit geschenkt. Die Prozess der Institutionalisierung der AIDS-Prävention auf kantonaler Ebene, eventuelle Formen der Planifikation der Gesundheitsvorsorge, bilden einen weiteren Teil des Untersuchungsinteresses.

Are we living longer but less healthy? Trends in mortality and morbidity in Catalonia (Spain), 1994-2011

Evidence on trends in prevalence of disease and disability can clarify whether countries are experiencing a compression or expansion of morbidity. An expansion of morbidity as indicated by disease have appeared in Europe and other developed regions. It is likely that better treatment, preventive measures and increases in education levels have contributed to the declines in mortality and increments in life expectancy. This paper examines whether there has been an expansion of morbidity in Catalonia (Spain). It uses trends in mortality and morbidity from major causes of death and links of these with survival to provide estimates of life expectancy with and without diseases and functioning loss. We use a repeated cross-sectional health survey carried out in 1994 and 2011 for measures of morbidity; mortality information comes from the Spanish National Statistics Institute. Our findings show that at age 65 the percentage of life with disease increased from 52% to 70% for men, and from 56% to 72% for women; the expectation of life unable to function increased from 24% to 30% for men and 40% to 47% for women between 1994 and 2011. These changes were attributable to increases in the prevalences of diseases and moderate functional limitation. Overall, we find an expansion of morbidity along the period. Increasing survival among people with diseases can lead to a higher prevalence of diseases in the older population. Higher prevalence of health problems can lead to greater pressure on the health care system and a growing burden of disease for individuals.

Transportation in Iowa: A Historical Summary, 1988

“This book traces the development of transportation in Iowa from territorial days to the 19 80s. It shows the evolution of the transportation systems; how they originated, progressed and functioned; their structural organizations; effectiveness in overcoming obstacles, under the guidance of state and federal legislation; and their impact upon the development of the state.” – From the Prologue, page xiii

Automated Traffic/Truck Weight Monitoring Equipment (Weigh-in-Motion), HR-282, 1988

This report documents work undertaken in the demonstration of a low-cost Automatic Weight and Classification System (AWACS). An AWACS procurement specification and details of the results of the project are also included. The intent of the project is to support and encourage transferring research knowledge to state and local agencies and manufacturers through field demonstrations. Presently available, Weigh-in-Motion and Classification Systems are typically too expensive to permit the wide deployment necessary to obtain representative vehicle data. Piezo electric technology has been used in the United Kingdom and Europe and is believed to be the basic element in a low-cost AWACS. Low-cost systems have been installed at two sites, one in Portland Cement Concrete (PCC) pavement in Iowa and the other in Asphaltic Cement Concrete (ACC) pavement in Minnesota to provide experience with both types of pavement. The systems provide axle weights, gross vehicle weight, axle spacing, vehicle classification, vehicle speed, vehicle count, and time of arrival. In addition, system self-calibration and a method to predict contact tire pressure is included in the system design. The study has shown that in the PCC pavement, the AWACS is capable of meeting the needs of state and federal highway agencies, producing accuracies comparable to many current commercial WIM devices. This is being achieved at a procurement cost of substantially less than currently available equipment. In the ACC pavement the accuracies were less than those observed in the PCC pavement which is concluded to result from a low pavement rigidity at this site. Further work is needed to assess the AWACS performance at a range of sites in ACC pavements.

Production of Acetic Acid for CMA Deicer, HR-304, 1988

Although the overall objective for undertaking this project is to help decide on the best way to produce CMA, the tasks to be performed deal primarily with acetic acid itself. The objectives of our part of this project can be restated here: A. Evaluate the cost and composition of potential low-cost fermentation substrates that are available in large quantity at central locations in Iowa. B. Compare the nutritional and physiological properties of a variety of homoacetogenic bacteria relative to acetic acid production, based on information available in the literature. C. Using both of these pools of information, evaluate the possibilities for use of substrates for acetic acid production that are significantly cheaper than the previous sugar, starch hydrolysate or whole corn based studies; also, compare the different acetogens encountered with the most commonly discussed acetogen, Clostridium thermoaceticum; arrive at conclusions on 1-3 of the best agriculture-derived substrates that should be further examined, and on 1-3 of the best organisms to evaluate experimentally. D. Collect experimental data at the tube and fermentor scale on 1-2 of the possibilities in C above. E. Comment on our understanding of acetic acid production possibilities from our perspective as microbiologists, and provide all this above information to Paul Peterschmidt for him to consider for his portion of this report. F. In addition, we would like to point out the possible advantage of examining the use of an agricultural by-product, corn steep liquor, as a direct, non-fermented feedstock for a non-acetic acid deicer.

Image Analysis of PCC and AC Pavements Using SEM Images, HR-346, 1994

The major objective of this work was to evaluate the potential of image analysis for characterizing air voids in Portland cement Concrete (PCC), voids and constituents of Asphalt Concrete (AC) and aggregate gradation in AC. Images for analysis were obtained from a scanning electron microscope (SEM). Sample preparation techniques are presented that enhance signal differences so that backscattered electron (BSE) imaging, which is sensitive to atomic number changes, can be effectively employed. Work with PCC and AC pavement core samples has shown that the low vacuum scanning electron microscope (LVSEM) is better suited towards rapid analyses. The conventional high vacuum SEM can also be used for AC and PCC analyses but some distortion within the sample matrix will occur. Images with improved resolution can be obtained from scanning electron microscope (SEM) backscatter electron (BSE) micrographs. In a BSE image, voids filled with barium sulfate/resin yield excellent contrast in both PCC and AC. There is a good correlation between percent of air by image analysis and linear traverse.

Precast Concrete Panel Thickness for Epoxy-Coated Prestressing Strands, Volume 2, HR-353, 1994

This final report for Phase 1 of the research on epoxy-coated, prestressing strands in precast prestressed concrete (PC) panels has been published in two volumes. Volume 1--Technical Report contains the problem description, literature review, and survey results; descriptions of the test specimens, experimental tests, and analytical models; discussions of the analytical and experimental results; summary, conclusions, and recommendations; list of references; and acknowledgments. Volume 2--Supplemental Report contains additional information in the form of appendix material for Volume 1 on the questionnaires, strand forces, geometry of the specimens, concrete crack patterns that formed in the strand transfer length and strand development length specimens, concrete strains in the strand transfer length specimens, and load-point deflections and strand-slip measurements for the strand development length specimens. Appendix A contains the questionnaires that were sent to the design agencies and precast concrete producers. A summary of the results to the questions on the surveys are given as the number of respondents who provided the same answers and as paraphrased comments from the respondents. Appendix B contains graphs of strand force versus time, strand force versus temperature, and strand force versus strand cutting sequence for the concrete castings. Appendix C contains figures that show the location of each specimen in the prestress bed, the geometrical configurations for the strand transfer length (T-type) specimens and strand development length (D-type) specimens, and the concrete cracks that developed in some of the T-type specimens when they were prestressed. Appendix D contains figures that show the concrete cracks that developed in the D-type specimens during the strand development length tests. For each of these tests, the sequence of the failure for the specimen is specified. Appendix E contains graphs of concrete strain versus distance from the end of the T-type specimens that were instrumented with internal embedment strain gages. Appendix F contains graphs of load versus load-point deflection and load versus strand-slip for the strand development length tests of the D-type specimens.

The Role of Magnesium in Concrete Deterioration, HR-355, Appendix, 1994

In the main report concerning the role that magnesium may have in highway concrete aggregate, over 20,000 electron microprobe data were obtained, primarily from automated scans, or traverses, across dolomite aggregate grains and the adjacent cement paste. Representative traverses were shown in figures and averages of the data were presented in Table II. In this Appendix, detailed representative and selected analyses of carbonate aggregate only are presented. These analyses were not presented in the main report because they would be interesting to only a few specialists in dolomite· rocks. In this Appendix, individual point analyses of mineral compositions in the paste have been omitted along with dolomite compositions at grain boundaries and cracks. Clay minerals and quartz inclusions in the aggregate are also not included. In the analyses, the first three column headings from left to right show line number, x-axis, and y-axis (Line number is an artifact of the computer print-out for each new traverse. Consecutive line numbers indicate a continuous traverse with distances between each point of 1.5 to a few μ-m. X-axis and y-axis are coordinates on the electron microscope stage). The next columns present weight percent oxide content of FeO, K20, CaO, Si02, Al203, MgO, SrO, BaO, MnO, Na20, and C02 (calculated assuming the number of moles of C02 is equal to the sum of moles of oxides, chiefly CaO and MgO), TOTAL (the sum of all oxides), and total (sum of all oxides excluding COi). In many of the analyses total is omitted.

Asphalt Cement Containing AC-13, HR-522, Final Report, 1988

Stopping and turning maneuvers on high traffic volume asphalt cement concrete surfaced roads and streets often cause distortion of the pavement. Distortion may show up as excessive rutting in the wheel path, shoving of the pavement and/or rippling of the surface. Often times repeated corrective work such as cold milling or heater planing is required in these areas to maintain the pavement surface in a reasonable condition. In recent years polymer additives have been developed for asphalt cement concrete paving mixes that show promise in improving the inplace stability of the pavements. AC-13 (Styrelf 13) available from Bitucote Products Company, St. Louis, Missouri is an asphalt cement that has been modified by an additive to exhibit characteristics of very high stability in asphalt mixes.

A Study of Fine Sand from Nine Mile Island at Dubuque, MLR-88-08, 1988

The specifications for concrete sand in Iowa have been used for many years with very good results. In several locations of the state, it is becoming more difficult to produce concrete sand consistently at a reasonable cost. Both ASTM and AASHTO have specifications for concrete sands that allow a finer, poorer graded sand than the Iowa specification. The ASTM and AASHTO specifications are based on the use of trial mix testing prior to construction. Iowa does not currently use the trial mix procedure.

Evaluation des campagnes de prévention contre le SIDA en Suisse : "La zone" : rapport final 1988

Cette étude est destinée à évaluer les effets des campagnes de Sida en Suisse auprès de jeunes en marge de la société que l'on qualifie de "zonards", en termes de modifications des représentations, attitudes et comportements face à cette maladie et aux manières de s'en protéger. Elle s'intéresse aussi aux modalités d'acquisition d'attitudes et comportements nouveaux, ainsi qu'à la manière dont les campagnes ont été accueillies et répercutées. [Auteurs, p. 5]
