The primary objective of the National Airspace System (NAS) is the transportation of passengers and cargo. It is no surprise, therefore, that passenger trip time performance is positively correlated with passenger satisfaction, airfare elasticity, and airline profits. Regulatory consumer information available to airline passengers provides measures of trip performance using only flight data (an...

Ribosome-inactivating proteins (RIPs) are N-glycosidases that remove a specific adenine from the sarcin/ricin loop of the large rRNA, thus arresting protein synthesis at the translocation step. In the present study, a protein termed tobacco RIP (TRIP) was isolated from tobacco (Nicotiana tabacum) leaves and purified using ion exchange and gel filtration chromatography in combination with yeast ...

BACKGROUND AND OBJECTIVES: The significance of road mobility in any nation cannot be far-fetched or beyond economic purpose, spatial interaction and social integration. It contributes enormously to the livelihood of human existence most especially by facilitating regional complementarity of trade, intervening opportunities, and spatial transferability. The objective of this stu...

In many wireless sensor network applications, the data collection sink (base station) needs to find the aggregated statistics of the network. Readings from sensor nodes are aggregated at intermediate nodes to reduce the communication cost. However, the previous optimally secure in-network aggregation protocols against multiple corrupted nodes require two round-trip communications between each n...

Readers may make verbatim copies of this document for non-commercial purposes by any means, provided that this copyright notice appears on all such copies. This paper combines fishing trip decisions – made before observing trip outcomes – with responses to set of double-bounded dichotomous choice CV questions regarding the outcome of the trip, to explore cognitive elements of choice and their i...

In this paper some experimental sequential models for the simulation of trip-chains are presented; the models have been calibrated on the base of a survey made in a medium-sized town. This work is part of a research, effected by the Department of Regional Planning of the University of Calabria, to forecast travel demand and to analyse travel behaviour of the transport system users. (Festa et al...

Travel websites and online booking platforms represent today’s major sources for customers when gathering information before a trip. In particular, community-provided customer reviews and ratings of various tourism services represent a valuable source of information for trip planning. With respect to customer ratings, many modern travel and tourism platforms – in contrast to several other e-com...

Every trip begins and ends with walking. Many factors affect our decisions on whether, when and where we walk: personal traits, built environment, trip purpose, urban context and other environmental and cultural variables. Although many models refer the importance of such issues, integrated and structured analysis that bring together these concerns is still lacking. Pedestrian accessibility has...

OBJECTIVE Effects of a 6-day snow skiing trip on 14 adolescents with limb deficiencies were explored. The purpose was to determine whether components of mastery and self-esteem could be identified. METHOD Participant observation data collection methods included videotape, interviews, daily progress notes by ski instructors, and a 1-month posttrip questionnaire. Data were analyzed for evidence...

transformation induced plasticity (trip) steels have a vast application in automotive industry because of theirhigh strength, high ductility and hence excellent energy absorption capacity. these characteristics of tripsteels are due to the existence of retained austenite in their microstructures in the ambient temperature, whichtransforms to the martensite phase during deformation. the microstr...
