The early-age thermal development of structural mass concrete elements has a significant impact on the future durability and longevity of the elements. If the heat of hydration is not controlled, the elements may be susceptible to thermal cracking and damage from delayed ettringite formation. In the Phase I study, the research team reviewed published literature and current specifications on mass concrete. In addition, the team observed construction and reviewed thermal data from the westbound (WB) I-80 Missouri River Bridge. Finally, the researchers conducted an initial investigation of the thermal analysis software programs ConcreteWorks and 4C-Temp&Stress. The Phase II study is aimed at developing guidelines for the design and construction of mass concrete placements associated with large bridge foundations. This phase included an additional review of published literature and a more in-depth investigation of current mass concrete specifications. In addition, the mass concrete construction of two bridges, the WB I-80 Missouri River Bridge and the US 34 Missouri River Bridge, was documented. An investigation was conducted of the theory and application of 4C-Temp&Stress. ConcreteWorks and 4C-Temp&Stress were calibrated with thermal data recorded for the WB I-80 Missouri River Bridge and the US 34 Missouri River Bridge. ConcreteWorks and 4C-Temp&Stress were further verified by means of a sensitivity study. Finally, conclusions and recommendations were developed, as included in this report.

The overall aim of the project has been to assess the extent to which data on the frequency of occurence of STDs [Sexually transmitted diseases] might be useful in the monitoring and evaluation of AIDS prevention programmes. The objectives have been to answer the following questions: (a) Can measures of STD occurence be used as an outcome measure of AIDS/HIV preventive efforts ? In particular: -> which diseases might be useful ? -> in what ways could they be used ? (b) If measures of STD occurence can be used in this way, is existing surveillance data in Western Europe adequate for the purpose ? If not why not ? (c) What do data from existing STD surveillance systems tell us about the success or failure of AIDS prevention to date ? (d) What needs to be done in order taht STD surveillance data in the countries of Western Europe could be used for this purpose ? [Authors, p. 4]

Most research current to the time of these projects was focused on use of Superpave mix designs on higher volume roads. Low volume roads have different requirements in terms of mix design, aggregate types, aggregate sources and project budgets. The purpose of this research was to determine if the Superpave mix design strategy for low volume roads was practical and economical. Eight projects were selected in five counties. The projects were completed in the summer of 1998. Performance evaluation of the resulting pavements was carried out annually. There was no significant increase in costs related to the use of Superpave. Nor were there any significant construction issues. There were some differences noted in placement and compaction in the field, but these were not serious.

O objetivo deste trabalho foi avaliar o ganho de peso vivo, a capacidade de suporte e a eficiência bioeconômica em pastos de Panicum maximum, cultivar Tanzânia, com aplicação de uma segunda dose de adubação nitrogenada no final do verão. Anualmente foram aplicados em cobertura: 50, 17,48, e 33,2 kg ha-1 de N, P e K, respectivamente, em novembro. A metade da área recebeu 50 kg ha-1 de N adicional em março. Os tratamentos foram pastos de capim-tanzânia com 50 e 100 kg ha-1 de N. Os piquetes foram submetidos ao pastejo rotacionado. Foram utilizados quatro animais por piquete, e animais adicionais foram colocados e removidos para manter resíduos semelhantes pós-pastejo. Não houve efeito da adubação nitrogenada sobre o ganho médio diário. No entanto, o pasto adubado com 100 kg ha-1 de N (1,8 UA ha-1) resultou em maior capacidade de suporte e maior produtividade (780 kg ha-1 por ano de PV) do que o adubado com 50 kg ha-1 de N (1,5 UA ha-1) e com 690 kg ha-1 por ano de PV, em média. A eficiência da conversão do N em produto animal foi de 1,8 kg de PV por hectare para cada quilograma adicional de N aplicado. O uso da adubação nitrogenada no final do verão é uma alternativa bioeconomicamente viável para a produção sustentável de carne.

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]

Individuals with disabilities have civil rights protection similar to that provided to individuals on the basis of race, sex, national origin, and religion. The advent of the Americans with Disabilities Act has improved these protections and brought this issue into the forefront. This book is not intended to be a legal translation of state or federal laws. Its purpose is to assist people with disabilities in understanding their rights. Please consult the Code of Iowa, the appropriate federal laws or an attorney if you need a legal interpretation.

This project resulted in the development of a proof of concept for a features inventory process to be used by field staff. The resulting concept is adaptable for different asset classes (e.g. culverts, guardrail) and able to leverage existing DOT resources such as the videolog and LRS and our current technology platforms including Oracle and our GIS web infrastructure. The concept examined the feasibility of newly available technologies, such as mobile devices, while balancing ease of use in the field. Implementation and deployment costs were also important considerations in evaluating the success of the project. These project funds allowed the pilot to address the needs of two DOT districts. A report of findings was prepared, including recommendations for or against full deployment of the pilot solution.

In order to reduce obesity and associated costs, policymakers are considering various policies, including taxes, to change consumers high-calorie consumption habits. We investigate two tax policies aimed at reducing added sweetener consumption. Both a consumption tax on sweet goods and a sweetener input tax can reach the same policy target of reducing added sweetener consumption. Both tax instruments are regressive, but the associated surplus losses are limited. The tax on sweetener inputs targets sweeteners directly and causes about five times less surplus loss than the final consumption tax. Previous analyses have overlooked this important point.

El projecte de recerca L'empresa xarxa a Catalunya. TIC, productivitat, competitivitat, salaris i beneficis a l'empresa catalana té com a objectiu principal constatar que la consolidació d'un nou model estratègic, organitzatiu i d'activitat empresarial, vinculat amb la inversió i l'ús de les TIC (o empresa xarxa), modifica substancialment els patrons de comportament dels resultats empresarials, en especial la productivitat, la competitivitat, les retribucions dels treballadors i el benefici. La contrastació empírica de les hipòtesis de treball l'hem feta per mitjà de les dades d'una enquesta a una mostra representativa de 2.038 empreses catalanes. Amb la perspectiva de l'impacte de la inversió i l'ús de les TIC no s'aprecia una relació directa entre els processos d'innovació digital i els resultats de l'activitat de l'empresa catalana. En aquest sentit, hem hagut de segmentar el teixit productiu català per a buscar les organitzacions en què el procés de coinnovació tecnològica digital i organitzativa és més present i en què la intensitat de l'ús del coneixement és un recurs molt freqüent per a poder copsar impactes rellevants en els principals resultats empresarials. Això és així perquè l'economia catalana, avui, presenta una estructura productiva dual.
