the effect of underground cavities in site seismic response was studied over the subway tunnels that are under construction in the city of karaj, using ambient noise measurements as well as numerical modeling. the idea for this research comes from the observation of differences in experimental site transfer function, calculated on more than 100 locations of the city, for the areas near the unde...

The historical centre of Rome is characterized by the presence of high thickness of anthropic cover with scarce geotechnical characteristics. This anthropic backfill could induce damages in urban areas, i.e. mainly differential settlements and seismic amplifications. About 1400 measurements from boreholes stored in the UrbiSIT database have been used to re-construct the anthropic backfill botto...

Informal settlements behave very dynamical over space and time and the number of people living in such housing areas is growing worldwide. The reasons for this dynamical behaviour are manifold and are not matter of this article. Nevertheless, informal settlements represent a status quo of housing and living conditions which is from a humanitarian point of view in the most cases below acceptable...

Settlement is a unit of space built up by man to live and where to find a living Settlement serves man in a number of areas, it is a defense against external and natural intruders, it is also a place of social and cultural interactions among people who live together for business and development [1]. Settlements have evolved in their different shapes, pattern and population based on the level of...

General declines in ecosystem service values (ESV) are acknowledged worldwide; however, rather few studies have quantitatively analyzed the interrelationship between changing rural settlements and values of ecosystem services. This study used the county of Tongyu in West Jilin Province, China, as a case study to analyze how changing rural settlements impact the values of ecosystem services on s...

Gas-lift pumps are devices for lifting liquid phase incorporating the gas phase to be injected in the bottom of liquid column. They are widely used in various industrial applications such as oil extracting in petroleum industries. Gas-liquid flow being the main part of the flow through these systems, flowing in vertical pipes of gas-lift pumps has different regimes namely bubbly, slug, chur...

We estimate deforestation and the carbon stock in 2740 (82 %) of the 3325 settlements in Brazil's Legal Amazonia region. Estimates are made both using available satellite data and a carbon map for the "pre-modern" period (prior to 1970). We used data from Brazil's Project for Monitoring Deforestation in Amazonia updated through 2013 and from the Brazilian Biomes Deforestation Monitoring Project...

the current manuscript presents the validation of smoothed particle hydrodynamics (sph) techniques for wave generation by underwater explosion, utilizing the so-called dualsphysics numerical model. this numerical method is used to analyze generated waves which are initiated by man-made or natural explosions below free surface level of sea. in spite of the modeling limitations (e.g. absence of o...
