Probe of anomalous neutrino couplings to W and Z in medium energy setup of a beta-beam facility
Capability of medium energy setup of a beta beam experiment to probe new
physics contributions to neutrino-W and neutrino-Z couplings are investigated.
We employ the effective lagrangian approach of Buchmuller and Wyler and obtain
95% confidence level limits on neutrino couplings to these gauge bosons without
assuming the flavor universality of the coupling of neutrinos. We show that a
beta beam facility can place 3 to 20 times more restrictive limits than present
ones on the deviations from the electron neutrino couplings in the Standard
Model.Comment: 22 pages, 10 figure
Tests of flavor universality for neutrino-Z couplings in future neutrino experiments
We investigate the physics potential of NuSOnG experiment to probe new
physics contributions to Z-neutrino-neutrino couplings in muon-neutrino
electron elastic and neutral-current deep-inelastic scattering processes. We
employ an effective Lagrangian approach and do not a priori assume universality
of the coupling of neutrinos to Z. We obtain 95% C.L. limits on possible
universality violating couplings.Comment: LaTeX with 6 figure
A Search for pair production of the LSP at the CLIC via RPV Decays
In this work we consider pair production of LSP tau-sneutrinos at the Compact
Lineer Collider. We assume that tau-sneutrinos decays in to e\textmu pair via
RPV interactions. Backgroundless subprocess
is analyzed in details. Achievable limits on
at and CL are
obtained depending on mass.Comment: 8 pages, 5 figure
The effect of vascular graft and human umbilical cord blood-derived CD34+ stem cell on peripheral nerve healing
AIM: There are many trials concerning peripheral nerve damage causes and treatment options. Unfortunately, nerve damage is still a major problem regarding health, social and economic issues. On this study, we used vascular graft and human cord blood derived stem cells to find an alternative treatment solution to this problem. MATERIAL AND METHODS: We used 21 female Wistar rats on our study. They were anesthetized with ketamine and we studied right hind limbs. On Group 1, we did a full layer cut on the right sciatic nerve. On Group 2, we did a full layer cut on the right sciatic nerve, and we covered synthetic vascular graft on cut area. On Group 3, we did a full layer cut on right sciatic nerve, and we covered the area with stem cell applied vascular graft. RESULTS: At the end of postoperative 8. weeks, we performed EMG on the rats. When we compared healthy and degenerated areas as a result of EMG, we found significant amplitude differences between the groups on healthy areas whereas there was no significant difference on degenerated areas between the groups. Then we re-opened the operated area again to reveal the sciatic nerve cut area, and we performed electron microscope evaluation. On the stem cell group, we observed that both the axon and the myelin sheet prevented degeneration. CONCLUSION: This study is a first on using synthetic vascular graft and cord blood derived CD34+ cells in peripheral nerve degeneration. On the tissues that were examined with electron microscope, we observed that CD34+ cells prevented both axonal and myelin sheath degeneration. Nerve tissue showed similar results to the control group, and the damage was minimal. © 2018 Ali Yilmaz, Abdullah Topcu, Cagdas Erdogan, Levent Sinan Bir, Barbaros Sahin, Gulcin Abban, Erdal Coskun, Ayca Ozkul
Measuring inequalities in the distribution of health workers by bi-plot approach: The case of Turkey
Optimal planning of the health workers is of vital importance for a country. Distribution of health workers among provinces in emerging markets is an important development criterion. In this study, biplot graphical approach is used to determine the distribution of health workers. The results of biplot analysis point out that the distribution of the healthcare staff in Turkey is unbalanced. The number of health workers should be planned and considered according to the desire, need, population, target and workload criteria. The new employment opportunities should be created and the workers should be encouraged to serve in low income regions by providing better conditions
