This educational video discusses and visualises the key steps of the complex interaction between cancer and the immune system. Essential steps of the cancer immune cycle take place in the tumour itself and in regional lymph nodes, with immune cells travelling between these distinct sites. Antigen-presenting cells such as dendritic cells migrate into the tumour microenvironment and take up tumou...

This year we enjoyed a large number of very highy meritorious applications for our annual Toxins Travel Awards.[...].

This quantitative study focused on the self-rating of multicultural counseling competencies by counselor education graduate students in a pre-post design. Twelve students participated in a ten day travel study course to Antigua, Guatemala in May, 2008. Prior to travel, students self-rated their levels of multicultural competency using the Multicultural Counseling Competencies Self Assessment (M...

STUDY OBJECTIVE To assess the impact of a combined intervention on children's travel behaviour, stage of behavioural change and motivations for and barriers to actively commuting to school. DESIGN A quasi-experimental trial involving pre- and post-intervention mapping of routes to school by active and inactive mode of travel and surveys of "stage of behaviour change" and motivations for and b...

introduction: among the united arab emirates (uae) population more and more people now consider travelling abroad. this is potentially problematic because travelling enhances exposure between hosts and pathogens and so people that travel are putting their health at risk. this concern makes it necessary that public education is provided to inform people of the risks of travelling abroad so that ...

A novel microactuated micro-XYZ stage with large travel distance and fine positioning capability has been demonstrated using the surface-micromachming technology. The micro-XYZ stage consists of three inplane translation stages driven by integrated scratch drive actuators. Two vertically stacked 45" micromirrors in orthogonal directions are employed to achieve vertical beam adjustment without u...

To overcome the limitations of the independent stacked hybrid actuator with multiple sensors, a new hybrid linear actuator combines the advantages of both technologies: piezo actuator for extremely high accuracy and motorized stage for long travel ranges. A hybrid linear actuator prototype is developed for testing in our satellite tracking antenna pointing control system. For the maximum absolu...

With the rapid development of transportation and logistics economy, the vehicle travel time prediction and planning become an important topic in logistics. Travel time prediction, which is indispensible for traffic guidance, has become a key issue for researchers in this field. At present, the prediction of travel time is mainly short term prediction, and the predication methods include artific...
