Evolution of transport infrastructure and its’ influence on the development of traveling and tourism

Development of tourism and transport infrastructure closely related and interwoven process. Tourism as mass phenomenon was a result of nascence and development of transport. It’s admitted fact. However emergence of transport area as direction of social-geographic research happened in the middle of XIX century. Before that transport infrastructure just had been forming, evolving and making direct influence on the world’s travelling at all. Main stages of conception and development of transport infrastructure of Europe in the context of territorial spreading of tourism are considered in this article. Key words: transport infrastructure, stages of development, factors of influence, road network, mobility.

Development of transport infrastructure in Lviv region for European Championships in 2012

In this article the author examines the main directions of improving the transport system of Lviv region and Lviv for the success of the European Championship in 2012, such as: improving road, rail and air traffic in our region. According to the government programs are planned activities for the development of different modes of transport and improving transport networks. Key words: transport infrastructure, European Championships, railway transport, railways, highways, airports, international transport corridors.

The effect of transport time from the assembly yard to the abattoir and resting time at the abattoir on pork quality

Over 1900 pigs, supplied by two producers, were first delivered to an assembly yard and then transported to a commercial abattoir. Transport times were 50 min and 2 h, and resting periods at the abattoir were < 30 min, 3 h and 6 h. Times were chosen to represent normal practices in Ontario. The colour and structure of the boneless loins were as sessed subjectively 24 h postmortem. The shorter (50 min) transport time was associated with the highest (P ≤ 0.05) incidence of pale and soft/exudative loins. A longer transport time reduced the incidence of pale and soft/exudative loins; it also increased (P ≤ 0.05) the incidence of dark and firm/dry loins; particularly during winter. A resting period of < 30 min resulted in the highest (P ≤ 0.01) incidence of pale and soft/exudative loins. A 3 h resting period significantly improved (P ≤ 0.01) quality by reducing the incidence of pale loins and soft/exudative loins. Extending the resting period from 3 h to 6 h provided inconsistent improvements in quality due to interactions with season (P ≤ 0.05) and producer/management (P ≤ 0.05). Considering transport time and resting period together further highlighted the importance of resting period at the abattoir. Three h resting period always improved (P ≤ 0.05) quality regardless of transport time, season or producer. Key words: Transport, resting period, pork quality, pale, soft and exudative, DFD

The architecture of plant vasculature and transport as seen with magnetic resonance microscopy

Water and photosynthate transport through plants has been studied extensively for the past three centuries. Few techniques are available that are capable of providing both physiological and anatomical information, and most are destructive in nature. We report the use of high resolution magnetic resonance microscopy (MRM) for the study of intact plant vasculature. Both two- (2-D) and three-dimensional (3-D) image acquisition protocols are employed wherein the plant vasculature can be readily distinguished from surrounding parenchymal tissue. In the 3-D image sets, the vasculature has been digitally segmented, allowing isolation of only the intact vascular architecture. The paths of water and photosynthate transport into several plant specimens have been visualized in this manner. Images of sugar beets, plants that store high concentrations of sucrose within the parenchyma, show contrast patterns between vasculature and parenchyma that are opposite to those seen in images acquired of an apple, fig, okra pod, kiwi fruit, and potato, plants that do not store high concentrations of sucrose. This suggests that transport and accumulation of photosynthates may be partially responsible for contrasts seen within images acquired of these plant specimens. Key words: transport, transpiration, sugar, MRI, magnetic resonance imaging, plants.
