The aims of this study were to determine the modulating role of ascorbic acid (AA) on rectal temperature (RT), heterophil to lymphocyte (H to L) ratio and aberrant behaviours of ostrich chicks transported by road for 4 h during hot-dry conditions. Twenty ostrich chicks aged 2.5 months, of both sexes and belonging to the Red Neck breed, served as subjects of the study. The chicks were assign...

This paper focuses on the development of a method for road network vulnerability analysis, from the perspective of capacity degradation, which seeks to identify the critical infrastructures in the road network and the operational performance of the whole traffic system. This research involves defining the traffic utility index and modeling vulnerability of road segment, route, OD (Origin Destin...

Dinghai district, the central area of Zhoushan, Zhejiang Province, lies on the biggest island of Zhoushan Archipelago. Owing to its marvelous island feature, Zhoushan has been attracting more and more people to Island Tourism, Agricultural Tourism and Culture Tourism. Shuangxiao Road is a transportation line through suburban area connecting the south to the north. However, the vicinity of Shuan...

In this paper, we demonstrate how to capture the robustness of a transportation network in the case of degradable links represented by decreasing capacities. In particular, with the use of Bureau of Public Road user link travel cost functions, we propose two relative total cost indices to assess transportation network robustness in the case of travel behavior associated with either user-optimiz...

The successful development of wildlife-transportation mitigation strategies requires access to timely and accurate information on the spatial and temporal movement patterns of wildlife. Unfortunately, conventional long term monitoring programs can be expensive and time consuming. In addition, expert-based approaches often marginalize local participation and knowledge. Alternative approaches to ...

This policy proposal will address the issue of public transportation as a means for sustainable development. Transportation is an issue that needs to be addressed because it has two deleterious effects on the environment. One is the effect of vehicle carbon dioxide, CO2, emissions on climate change and the second stems from other vehicle emissions that cause air pollution leading to negative he...

This study defines a methodology to compute unitary costs for freight transportation modes. The main objective was to gather relevant costs data to support the formulation and evaluation of railway, road, pipelines and port projects. This article will concentrate on the following steps: Compilation and analysis of relevant modal cost studies, Methodological adjustments to make cost figures comp...

The characterisation of transportation hazards is paramount for protective packaging validation. It is used to estimate and simulate the loads and stresses occurring during transport which are essential to optimise packaging and ensure that products will resist the transportation environment with the minimum amount of protective material. Characterising road transportation vibrations is rather ...
