earthquakes travel times inversion for determination of velocity structure of crust is one of the most important objectives in seismology. in the simultaneous inversion method, the parameters of earthquakes and velocity model are determined initially and are improved during inversion steps. in this study, we have used more than 22000 calculated travel times for first arrivals of 6000 earthquake...

Localized ecological interactions can generate striking large-scale spatial patterns in ecosystems through spatial self-organization. Possible mechanisms include oscillating consumer-resource interactions, localized disturbance-recovery processes and scale-dependent feedback. Despite abundant theoretical literature, studies revealing spatial self-organization in real ecosystems are limited. Rec...

north-east khorasan is one of the most active regions in the world because of is setting on the alpine-himalayan belt. historical and geological backgrounds suggest that this region has experienced many destructive earthquakes throughout history. compared with the historical background, the seismicity of the region, in the present century, is better known both from the macroseismic and instrume...

BACKGROUND Pregnant women who travel to malarious areas and their clinicians need data on the safety of malaria chemoprophylaxis. METHODS The effect of exposure to mefloquine on pregnancy and offspring outcomes was evaluated using the F. Hoffmann-La Roche global drug safety database for the time frame 31 January 1986 through 26 October 2010. We investigated pregnancy and fetal outcomes in mat...

BACKGROUND Since a decline in activity levels occurs in adolescence, active transport could be important to increase daily physical activity in older adolescents (17-18 years). To promote active transport, it is necessary to be aware of the barriers and facilitators of this type of transport, but also of other transport modes. This study sought to uncover the factors influencing the choice of t...

Travel decisions during the COVID-19 pandemic might be substantially influenced by destination-based attributes, in particular, health safety measures at airports. In current study, we aimed to assess effects of perceived importance Sharm El Sheikh airport on intention international passengers revisit destination, which reflect their behavioral control for traveling other tourism destinations. ...

At the beginning of March 2020, Coronavirus pandemic was acknowledged as a great confrontation that shook travel organisations’ core. Indeed, it provides such profound disturbance to industry. It gives preview Malaysian travellers’ discernments in distinctive point time - times COVID-19 linked worldwide lockdown and restriction movement order. Therefore, this study examines relationship between...
