“…Centrifuges are applied in various disciplines mainly in material and particle technology like for separation (Sahuquillo et al, 1999;Kuang et al, 2015), for nanomaterials classification (Wohlleben, 2012), casting (Huisman et al, 1994;Liu and Barnett, 2002;Dikel et al, 2005;Velhinho and Rocha, 2011), combustion (Merzhanov, 1995), but also in areas like geology (Gopal Madabhushi, 2004;Costa et al, 2016), life sciences in plants (Musgrave et al, 2009;Herranz et al, 2013;Hoson and Wakabayashi, 2015), single cells (Loesberg et al, 2006;Tavakolinejad et al, 2015), animals (van Loon, 2001;van Loon et al, 2005;Tateishi et al, 2015) and humans (Akima et al, 2005;van Loon et al, 2012;Goswami et al, 2015).…”

Due to the cumbersome nature of performing real microgravity-spaceflight research scientists have been searching for alternatives to perform simulated microgravity or partial gravity experiments on Earth. For more than a century one uses the slow rotating clinostat as developed by von Sachs at the end of the nineteenth century. Since then, the fast rotating clinostat, the 3D clinostat or the random positioning machine, the rotating wall vessels, tail suspension and bed rest head down tilt and lately the levitating magnets have been introduced. Several of these simulation systems provide some similarities of the responses and phenotypes as seen in real microgravity experiments. However, one should always realize that we cannot reduce gravity on Earth, other than the relative short duration free fall studies in e.g., drop towers or parabolic aircraft. In this paper we want to explore the possibility to apply centrifuges to simulate microgravity or maybe better to simulate hypo-gravity. This Reduced Gravity Paradigm, RGP is based on the premise that adaptations seen going from a hypergravity level to a lower gravity are similar as changes seen going from unit gravity to microgravity.

“…Suzuki et al [15] studied the effect of cement treated soil as a backfill material behind the reinforced soil walls under different seismic conditions. Costa et al [16] investigated the time dependent deformations in geotextile reinforced soil walls. Deformations of geogrid reinforced soil walls through centrifuge model tests at constant gravity under the effects of molding water content and stiffness of the geogrid were presented by Balakrishnan and Viswanadham [17].…”

Changing the natural conditions of soil creates unexpected stress increments in slope stability projects, which are required high amount of soil excavation near the highways and railways or braced cut systems. Some safety problems can occur during this application under different loading cases. In addition, slope stability design requires economical solutions. Slope-supporting structures should be designed with most effective solution according to these signified requirements. A slope stability problem considering deep excavations in front of the reinforced soils are studied within this study in all its parts, after an extensive review of the literature. Geotextile (GT), geogrid (GG) and steel strip (SS) reinforcements are used to increase the stability conditions of slope during both experimental procedure and modelling process with Plaxis software. Each reinforcement type provided the bearing capacity enhancement and showed that unique displacement behavior. Therefore, most effective reinforcement member can be chosen in design procedure and construction phase in the site according to the bearing capacity and displacement requirements according to presented values.

“…There is also study to improve behaviour of fine backfill by treating with lime [3]. There are also studies regarding performance of reinforced earthwalls considering effects of various factors [9][10][11][12][13][14][15][16][17][18]. Behaviour of reinforced earth wall under strip loading is studied experimentally [9].…”

İnşa edilmelerinin kolaylığı ve deprem yükleri altında sergiledikleri performanstan dolayı donatılı zemin uygulaması ile inşa edilen istinat duvarlarına olan ilgi dünya çapında artmaktadır. Bu çalışmada 450 mm yüksekliğinde kum ve kil dolguya sahip donatılı istinat duvarları inşa edilerek köprü ayağı yükleme şartlarında test edilmiştir. Elde edilen test sonuçlarından yararlanılarak sonlu elemanlar modeli oluşturulmuştur. Sonlu elemanlar ile yapılan parametrik çalışmada donatı rijitliği, donatı sıklığı ve donatı uzunluğunun temel oturmasına, istinat duvarı boyunca oluşan yatay deplasmanlara, her bir donatı üzerinde oluşan maksimum çekme kuvveti ile toplam maksimum çekme kuvvetine ve şev duyarlılığı üzerindeki etkileri araştırılmıştır.
