Safety Evaluation of Turbo-Roundabouts with and without Internal Traffic Separations Considering Autonomous Vehicles Operation
2021
The paper presents a microsimulation approach for assessing the safety performance of turbo-roundabouts where Cooperative Autonomous Vehicles “CAVs” have been introduced into the traffic mix alongside conventional vehicles “CVs”. Based on the analysis of vehicle trajectories from VISSIM and subsequent analysis of traffic conflicts through the Surrogate Safety Assessment Model (SSAM), the research aims to evaluate the safety benefits of turbo-roundabouts where the lanes are physically separated by raised curbs, compared to roundabouts without such curbs. The paper will then describe the methodological path followed to build VISSIM models of turbo-roundabouts with and without raised curbs in …
Análisis de la variación y estabilización de los parámetros de programación del implante coclear en relación al tiempo post implantación
2023
La Tesis Doctoral que se presenta lleva por título “Análisis de la variación y estabilización de los parámetros de programación del implante coclear en relación al tiempo post implantación”, y se trata de un estudio retrospectivo sobre la estabilización de estos parámetros durante los primeros 5 años tras la realización de la cirugía. La universalización de la implantación coclear a lo largo de los últimos años ha supuesto cambios importantes en la perspectiva y pronóstico a largo plazo de los pacientes con hipoacusia neurosensorial. El número de pacientes implantados está incrementándose en los últimos años, y esto supone un aumento tanto en el número de cirugías como en el seguimiento pos…
Evaluation of biogas production and usage potential
2016
The aim of the research is the development of theoretical and methodical bases for determining the feasibility of plant raw materials growing for its further bioconversion into energy resources and tec hnological materials to maximize profit from business activities. Monograph, statistics, modelling and abstract logical methods have been used during the research. Directions of biogas usage have been examined. Biogas yields from different crops have been analyzed. It has been determined that high methane yields can be provided from root crops, grain crops, and several green forage plants. So, forage beet and maize can provide more than 5,500 m3 of biogas per hectare. Attention is paid to the…
More nature in the city
2020
According to projects and practices that the Italian botanists and ecologists are carrying out for bringing “more nature in the city”, new insights for a factual integration between ecological perspectives and more consolidated aesthetic and agronomic approaches to the sustainable planning and management of urban green areas are provided.
Relationships between Heavy Metal Concentrations in Greater Celandine (Chelidonium majus L.) Tissues and Soil in Urban Parks
2023
Anthropogenic ecological ecosystems create favourable conditions for the growth of the nitrophilous medicinal species Chelidonium majus in six urban parks in Southern Poland. This study focuses on the concentrations of trace elements in the soils, leaves, stems, and rhizomes of greater celandine. The soil samples were taken only in the humus horizon (A), which averaged approximately 15 cm in thickness under the clumps of Ch. majus. Regarding the reaction, the soil samples tested can be described as slightly acidic (5.6–6.8 in KCl) to alkaline (7.1–7.4 in H2O). Organic carbon content at all sites is high, ranging from 3.2% to 13.6%, while the highest total nitrogen (Nt) content is 0.664%. Th…
Pathways for the amplification of agroecology in African sustainable urban agriculture
2020
A growing awareness that highly intensified agricultural systems have made a substantial worldwide contribution to the worsening of the resilience capacity of natural ecosystems has, over the last twenty years, brought general attention to agroecological management models. This aspect is even more evident in industrial agriculture, which is based on the use of multiple chemical products derived from non-natural synthesis. In more developed countries, a new idea of ecology linked to agricultural production has been increasingly developed and, for this reason, there has been a greater diffusion of differentiated agricultural models taking into consideration the environmental impact of product…
Fertility and immunosuppression in allogeneic uterus transplantation
2015
A pesar de los avances en medicina reproductiva alcanzados durante las últimas tres décadas, la esterilidad absoluta de origen uterino (AUFI, por sus siglas en inglés), a día de hoy, carece de tratamiento. Ésta, puede ser causada tanto por la ausencia del útero (congénita o adquirida) o la no funcionalidad del mismo [1, 2]. Cálculos en el Reino Unido han demostrado que hay alrededor de 12000 a 15000 mujeres en edad reproductiva con infertilidad uterina en dicho país [3]. No hay cálculos correspondientes a España, pero extrapolando datos sobre prevalencia de causas de AUFI, se estima que puede haber alrededor de 2000-3000 mujeres en edad fértil que no tienen ninguna oportunidad de ser biológ…

Ulteriori studi sul comportamento agronomico di piante di fragola prodotte in Sicilia
2010
Nowadays, Sicilian growers moved fron traditional summer planting with cold-stored strawberry plants to winter planting using fresh plants. Fresh plants let di anticipate and expand the harvesting period from December to May and produce strawberries with better qualitative parameters. Fresh bare root plants are produced mainly in Spain and Poland but in the last years mountain's nurseries near yhe cultivation fields were set up in Sicily. This work consisted of comparing fresh bare root plants of three cultivars (Camarosa, Candonga, Tudla) coming from three Sicilian and one Poland nurseries. the Sicilian plants were the earliest and gave a yield higher than that of the plants imported from …
Colour alone matters : no predator generalization among morphs of an aposematic moth
2018
Local warning colour polymorphism, frequently observed in aposematic organisms, is evolutionarily puzzling. This is because variation in aposematic signals is expected to be selected against due to predators' difficulties associating several signals with a given unprofitable prey. One possible explanation for the existence of such variation is predator generalization, which occurs when predators learn to avoid one form and consequently avoid other sufficiently similar forms, relaxing selection for monomorphic signals. We tested this hypothesis by exposing the three different colour morphs of the aposematic wood tiger moth, Arctia plantaginis, existing in Finland to local wild-caught predato…
