Experimental investigation of the uplift capacity of group anchor plates embedded in sand
Emirler, Buse,Tolun, Mustafa,Laman, Mustafa Techno-Press 2016 Geomechanics & engineering Vol.11 No.5
In this study, the uplift capacity of anchor plates embedded in sand was investigated by conducting model tests. Square shaped anchors were used in the tests and parameters such as relative density of sand, embedment ratio (H/B), spacing ratio between anchors (S/B) and anchor configuration affecting the uplift capacity were investigated. Breakout factor and group efficiency which are dimensionless parameters were used to show the results. A series of finite element analyses and analytical solutions were additionally performed to ascertain the validity of the findings from the laboratory model tests and to supplement the results of the model tests. It can be concluded that the embedment depth in dense sand soil condition is the most important parameter with respect to the other parameters as to influencing the uplift capacity of group anchors.

Objective: The umbilical cord consists of two arteries and one vein and it functions in the transport between the maternal and fetal circulation. Biochemical analysis of fetal cord blood (FCB) during delivery could be beneficial in terms of understanding the fetal environment. In this study, we aimed to investigate oxidative parameters like malondialdehyde (MDA), superoxide dismutase (SOD), and catalase (CAT) levels in FCB during delivery. Methods: We collected FCB samples during caesarean section. Our study included 33 depressed mothers and 37 healthy controls. We investigated MDA, SOD, and CAT levels in FCB samples. Results: We found no significant difference between groups in terms of MDA (p=0.625), SOD (p=0.940), and CAT (p=0.413) levels. Conclusion: Our study reveals probable protective effects of the placenta from oxidative stress. Future studies should include larger samples.

Leading order analysis of neutrino induced dimuon events in the CHORUS experiment
CHORUS Collaboration,Kayis-Topaksu, A.,Onengut, G.,van Dantzig, R.,de Jong, M.,Oldeman, R.G.C.,Guler, M.,Kama, S.,Kose, U.,Serin-Zeyrek, M.,Tolun, P.,Catanesi, M.G.,Muciaccia, M.T.,Bulte, A.,Winter, K North Holland 2008 Nuclear Physics, Section B Vol. No.
We present a leading order QCD analysis of a sample of neutrino induced charged-current events with two muons in the final state originating in the lead-scintillating fibre calorimeter of the CHORUS detector. The results are based on a sample of 8910 neutrino and 430 antineutrino induced opposite-sign dimuon events collected during the exposure of the detector to the CERN Wide Band Neutrino Beam between 1995 and 1998. The analysis yields a value of the charm quark mass of m<SUB>c</SUB>=(1.26+/-0.16+/-0.09)GeV/c<SUP>2</SUP> and a value of the ratio of the strange to non-strange sea in the nucleon of κ=0.33+/-0.05+/-0.05, improving the results obtained in similar analyses by previous experiments.
