Paleopatología dental de una muestra esquelética del área funeraria del suburbio oriental de Tarraco (siglo I-III d. C.)

Los dientes son una importante fuente de información en el estudio de poblaciones del pasado. El estudio de las enfermedades dentales en restos esqueléticos antiguos busca reconstruir la forma de vida de las poblaciones antiguas relacionadas con su estado de salud y enfermedad.

Location models for airline hubs behaving as M/D/c queues

Models are presented for the optimal location of hubs in airline networks, that take into consideration the congestion effects. Hubs, which are the most congested airports, are modeled as M/D/c queuing systems, that is, Poisson arrivals, deterministic service time, and {\em c} servers. A formula is derived for the probability of a number of customers in the system, which is later used to propose a probabilistic constraint. This constraint limits the probability of {\em b} airplanes in queue, to be lesser than a value $\alpha$. Due to the computational complexity of the formulation. The model is solved using a meta-heuristic based on tabu search. Computational experience is presented.

Safer Construction and Maintenance Safer Construction and Maintenance Practices to Minimize Potential Liability by Counties from Accidents, September 1979

Tort claims resulting from alleged highway defects have introduced an additional element in the planning, design, construction, and maintenance of highways. A survey of county governments in Iowa was undertaken in order to quantify the magnitude and determine the nature of this problem. This survey included the use of mailed questionnaires and personal interviews with County Engineers. Highway-related claims filed against counties in Iowa amounted to about $52,000,000 during the period 1973 through 1978. Over $30,000,000 in claims was pending at the end of 1978. Settlements of judgments were made at a cost of 12.2% of the amount claimed for those claims that had been disposed of, not including costs for handling claims, attorney fees, or court costs. There was no clear time trend in the amount of claims for the six-year period surveyed, although the amount claimed in 1978 was about double the average for the preceding five years. Problems that resulted in claims for damages from counties have generally related to alleged omissions in the use of traffic control devices or defects, often temporary, resulting from alleged inadequacies in highway maintenance. The absence of stop signs or warning signs often has been the central issue in a highway-related tort claim. Maintenance problems most frequently alleged have included inadequate shoulders, surface roughness, ice o? snow conditions, and loose gravel. The variation in the occurrence of tort claims among 85 counties in Iowa could not be related to any of the explanatory variables that were tested. Claims appeared to have occurred randomly. However, using data from a sub sample of 11 counties, a significant relationship was shown probably to exist between the amount of tort claims and the extensiveness of use of warning signs on the respective county road systems. Although there was no indication in any county that their use of warning signs did not conform with provisions of the Manual on Uniform Traffic Control Devices (Federal Highway Administration, Government Printing Office, Washington, D.C., 1978), many more warning signs were used in some counties than would be required to satisfy this minimum requirement. Sign vandalism reportedly is a problem in all counties. The threat of vandalism and the added costs incurred thereby have tended to inhibit more extensive use of traffic control devices. It also should be noted that there is no indication from this research of a correlation between the intensiveness of sign usage and highway safety. All highway maintenance activities introduce some extraordinary hazard for motorists. Generally effective methodologies have evolved for use on county road systems for routine maintenance activities, procedures that tend to reduce the hazard to practical and reasonably acceptable levels. Blading of loose-surfaced roads is an example of such a routine maintenance activity. Alternative patterns for blading that were investigated as part of this research offered no improvements in safety when compared with the method in current use and introduced a significant additional cost that was unacceptable, given the existing limitations in resources available for county roads.

Estatuto juridico y urbanismo en la Tingitana (s. I-VII d.C.). Septem-Septon

La ciudad de Ceuta hace su aparición en las fuentes literarias históricas como 'statio' antes de ser citada, en la Antigüedad tardía, como un fuerte vándalo, y después como ciudad bizantina capital de la Mauretania Secunda. Ni las fuentes escritas, ni las fuentes arqueológicas ofrecen datos concluyentes sobre la adopción de un estatuto jurídico romano antes de su etapa bizantina.

Influência de fungos micorrízicos arbusculares sobre o crescimento de dois genótipos de aceroleira (Malpighia emarginata D.C.)

O objetivo deste trabalho foi avaliar o efeito da inoculação de fungos micorrízicos arbusculares (FMA) no crescimento da aceroleira (Malpighia emarginata D.C.). Estacas semi-lenhosas de dois genótipos de aceroleira (Barbados e Miró), com dois pares de folhas, foram plantadas para enraizamento das mudas. Após dois meses, montou-se um experimento em telado, inoculando dois isolados de FMA (Gigaspora margarita Becker & Hall e Glomus etunicatum Becker & Gerdemann) nessas mudas, em solo com 3 mg/dm³ de fósforo. Ao término do experimento (110 dias), observou-se que a inoculação de FMA proporcionou maior altura, aumentou a biomassa seca da parte aérea e a área foliar, e evidenciou correlações positivas entre algumas características de crescimento da planta e o número de esporos de FMA, em comparação com as plantas não colonizadas. Melhores respostas de crescimento foram obtidas nos dois genótipos com a inoculação de G. margarita. A concentração de P na parte aérea das plantas não variou significativamente entre os tratamentos com inoculação. A associação com FMA reduziu em pelo menos dois meses o tempo de produção de mudas dos dois genótipos de aceroleira.

Retórica, comedia, diálogo. La fusión de géneros en la literatura griega del s. II d.C.

Lucien de Samosate est sans doute un écrivain difficile a classer. Certains en font le roi du pastiche. Pour nous il s'agit. par contre, d'un écrivain lucide et intelligent qui cherche dans la tradition les éléments qui peuvent l'aider a comprendre le présent et a en faire une critique parfois féroce.
