Tunnelling transit time for a frustrated total internal reflection (FTIR) in a double–prism experiment was measured using microwave radiation. We have found that the transit time is of the same order of magnitude as the corresponding transit time measured either in an undersized wave-guide (evanescent modes) or in a photonic lattice. Moreover we have established that in all such experiments the...

[Purpose] This study aimed to examine the effects of interventions on constipation and to provide basic data for physical therapy in internal medicine. [Subjects and Methods] The colon transit times of 30 subjects were measured and after the interventions. Fifteen subjects were assigned to a Maitland orthopedic manual therapy group, and 15 subjects were assigned to a dietary fiber group. [Resul...

UNLABELLED The purpose of this study was to determine the orogastric transit time of standard 131I capsules and the incidence of transit delay. METHODS We studied 58 consecutive subjects receiving outpatient diagnostic and therapeutic 131I dosages. A standard ion chamber survey meter, placed over the left upper quadrant of the abdomen, monitored orogastric transit. Each subject had ample wate...

BACKGROUND Most public transit users walk to and from transit. We analyzed the relationship between transit commuting and objectively measured physical activity. METHODS Adults aged 20 to 65 working outside the home (n = 1237) were randomly selected from neighborhoods in Seattle and Baltimore regions. Neighborhoods had high or low median income and high or low mean walkability. Mean daily min...

The wireless motility/pH capsule (WMC) is an orally ingested, nondigestible, data recording device that enables the simultaneous assessment of regional and whole gut transit. Approved by the US Food and Drug Administration for the evaluation of patients with suspected delayed gastric emptying and the evaluation of colonic transit time in patients with chronic idiopathic constipation, this capsu...

CONTEXT Esophageal dysphagia is the sensation that the ingested material has a slow transit or blockage in its normal passage to the stomach. It is not always associated with motility or transit alterations. OBJECTIVES To evaluate in normal volunteers the possibility of perception of bolus transit through the esophagus after swallows of liquid and solid boluses, the differences in esophageal ...

Already, the formation of the WTO did not halt the proliferation of new RTAs. There has been an enormous increase in Preferential Trade Agreements (PTAs) in the last twenty years. In fact, RTAs legitimacy is well recognised under GATT/WTO. By their very nature, such arrangements favour imports from members of the grouping and discriminate against imports from other countries. This departure fro...

Preferential trade agreements (PTAs) on services have proliferated since 2000. This working paper briefly presents the expansion of the dataset initially developed in Marchetti and Roy (2008). The data permits to assess the extent to which market access commitments undertaken by WTO Members in PTAs go beyond GATS commitments and offers made in the context of the Doha Development Agenda. The dat...

This study is an empirical attempt to find out whether under sanctions Iran’s trade direction has shifted away from Europe (trade policy of de-Europeanization) towards Asia (trade policy of Asianization). The analysis is conducted using a panel-gravity trade model to analyze bilateral trade pattern between Iran and 50 countries from the EU and Asia during the period 2006–2013. To this end, the ...

With IP networking booming in Africa, promotion of BGP peering in the region emerge, and changes in the transit behavior of ISPs serving Africa are expected. However, little is known about the IP transit topology currently forming the African Internet. Enhancing the RIPE Atlas infrastructure, we evaluate the topology interconnecting ISPs based on the continent. We reveal a variety of ISP transi...
