  • Analysis of dosimetric characteristics of flattening filter free photon beams and comparison with regular beams 
    Kourteli, C.; Benrachi, F. (Université Frères Mentouri - Constantine 1, 2016-12-14)
    Basic dosimetric properties of 6 MV and 10 MV photon beams from a linear accelerator operating without the flattening filter have been analyzed. These include dose rate data, depth dose dependencies, lateral profiles and ...
  • Evaluation of different parameters influencing the radiotherapy treatment plans (VMAT-RapidArc) 
    Saadi, A.; Benrachi, F.; Bali (Université Frères Mentouri - Constantine 1, 2016-12-14)
    Volumetric modulated arc therapy (VMAT)is a modern technique of high accuracy radiotherapy that allows the irradiation of tumor volume using a complete arc instead of fixed beams and protects the healthy tissues in the ...
  • New calculation of L1 subshell yields fluorescence of heavy elements 
    Sahnounea, Y.; Kahoula, A.; Kasrid, Y.; Deghfele, B.; Medjadic (Université Frères Mentouri - Constantine 1, 2016-12-15)
    The analytical methods based on X-ray fluorescence have a great importance for a number of practical applications in a variety of fields including atomic physics, X-ray fluorescence surface chemical analysis, medical ...
  • Relativistic K shell decay rates and fluorescence yield for Fe 
    Kahoula, B.; Kasric, Y.; Sahnounea; Deghfele; Khalfallaha; Sampaiogand (Université Frères Mentouri - Constantine 1, 2016-12-14)
    In this work, we derive the K-shell fluorescence yield using a Dirac-Fock model. To compute, radiationless and radiative transition rates we have used the MCDF code of Desclaux and Indelicato [1-3]. The wave functions were ...
  • Inflationary models and applications 
    Djeha, K.; Si Lakhal, B. (Université Frères Mentouri - Constantine 1, 2016-12-15)
    Study the cosmic microwave background: polarization and anisotropy.The inflationary model has been proposed to address the shortcomings of the standard model of cosmology. This cosmological model offers both a solution to ...
  • Dose Evaluation in adaptive radiotherapy in head and neck cancers 
    Chibane, B. I.; Benrachi, F.; Bali, M.S. (Université Frères Mentouri - Constantine 1, 2016-12-15)
    Recent developments in radiotherapy techniques, particularly VMAT technique is a tool of choice in the treatment of tumors with complex shapes such as head and neck cancers. Patients with head and neck cancer are prone ...
  • The numerical study of the origin of the ultra high energy cosmic rays with CRPropa. 
    Bouchachi, D.; Attallah, R. (Université Frères Mentouri - Constantine 1, 2016-12-14)
    The origin of ultra-high-energy cosmic rays is one of the most enigmatic questions in modern physics. The study of a such high-energy particles is a new and active research area where scientists wish to find the still-unknown ...
  • Path Integral Solution of a Singular Oscillator Potential 
    Bekhouche, S.; Bentag, B. (Université Frères Mentouri - Constantine 1, 2016-12-15)
    By path integral formulation and delta functional technics we calculated the propagator of singular oscillator. We have foundthe discrete spectrum and the corresponding wave functions.
  • The study of cosmic rays in the high-energy and the possibility monitored with telescope JEM EUSO 
    Attouia, T.; Kalli, S. (Université Frères Mentouri - Constantine 1, 2016-12-14)
    Ever since the discovery of cosmic rays by Victor Hess [Hes12] in 1912 great efforts have been undertaken to understand the origin of cosmic rays up to the highest energies of 1021eV. A common detection method utilizes the ...
  • Evaluation of radioactivity levels in sediment samples collected from Beni Haroun dam using high resolution gamma-ray spectrometry 
    Bouhila, G.; Azbouche; Belamri, M. (Universté Frères Mentouri - Constantine 1, 2016-12-14)
    The majority of exposure to radiation comes from natural sources. Therefore, the knowledge of radionuclide distribution and radiation levels in the environment is important. The purpose of the study is twofold: first to ...
