Authors: Gavardashvili Givi , Vartanov Martin 
Published: February 2023

Abstract
Based on theoretical and long-term field researche, the article provides assessment of the management of engineering and technical structures of the Zhinvali hydroengeneering complex. The methodology and quantitative assessment of the risk of loss resulting from accidents at hydraulic structures are described. The implementation of the recommendations of scientific researche related to the protection of the waters of the Zhinvali reservoir will allow to extend its service life for at least another twenty years, which, subject to one-time-only investments in protection measures in the amount of 35 million GEL (1 USA Dollar - 2,90 GEL), will provide an opportunity to bring the amount of direct and indirect loss prevented to 25 million GEL per year. The calculation showed that rational management of the reservoir will allow, with an internal rate of return (IRR) of 42%, to accumulate net present value (NPV) in the amount of 87.6 million GEL over twenty additional years of operation, which in turn indicates a high efficiency of investments in the protection of reservoir waters.
Multi-objective two-stage stochastic optimization model for post-disaster waste management

Published: February 2023

Abstract
Post-disaster waste management is one of the most crucial tasks in the recovery phase of the disaster cycle, and it was created to assist affected communities in returning to a stable state following a disaster. To develop an efficient post-disaster waste management strategy, this study presents a multi-objective two-stage stochastic mixed integer linear programming model for post-disaster waste management. The proposed mathematical model was developed based on a mixed strategy of on-site and off-site waste separation in the supply chain. This study aims to minimize not only the total cost and the environmental impact to provide waste flow decisions and choose collection and separation sites, recycling sites, landfill sites, and incineration sites throughout the supply chain under the uncertain situation. To solve a multi-objective problem, a normalized weighted sum method is used to find the solution. A numerical case based on realistic data is presented to validate and verify the proposed model. Based on the numerical example, the results demonstrated that the implementation of the mixed strategy for waste separation with the consideration of uncertain situations can reduce the total cost, balance the environmental impact, and determine the unexpected situation in the post-disaster waste supply chain efficiently.

Optical properties of Rhodamine B Dye mixed with Polyvinylpyrrolidone (PVP ) as a matrix
Authors: Ali Abdullah Basil 
Published: February 2023

In the present work, the spin casting method has been utilized for preparing different concentrations of Rhodamine B (Rh B) (5%,10% and 15%) mixed with a transparent polymer Polyvinylpyrrolidone (PVP) as a matrix. The spectral characteristics of the prepared samples are studied by absorption, transmission, reflection (the wavelength region from 300 nm to 900 nm) and fluorescence spectroscopy (the wavelength region from 550 nm to 800 nm). The calculated Stokes shift between the absorption and emission of Rh.B reflects the displacement in potential surface between the ground and the excited states. The analysis of the spectral behavior of the absorption coefficient in the absorption region reveals an direct allowed transition with a band gap of 2.07 eV . The values of some important parameters (refractive index n and extinction coefficient K ) of polymer thin film are determined from these spectra.

Authors: Ali Al-Helaly Emad , J. Muhsin Israa 
Published: February 2023

In this historical survey, we have reviewed researches of shadow phenomenon in satellite images since the beginning of the need for treatment and interpretation in remote sensing. Because remote sensing enters into many applications and is shared with many sciences, studies on the phenomenon of shadows have been conducted with in different ways. In this review, we attempted to link the evolution of remote sensing techniques with growing resolution of space images as research progresses in the treatment of shadows, because the evolution of space sensor abilities sure increases the options for the interpreter and processor of the satellite image in remote sensing and other purposes. There were also problems that appeared only with the emergence of high-resolution satellite images (0.6 meters) such as the problem of the semi-shadow region. Some researches included some weaknesses and limitations that could not be comprehensive for all satellite images, for all regions of the earth, or for all target shadows.

Authors: Ali Shakir Anfal 
Published: February 2023

In our experimental pure and cobalt (Co) doped Zinc oxide (ZnO) thin film were prepared onto glass substrate chemical spray pyrolysis technique at 400 oC, X-ray diffraction, Atomic force microscope and optical properties were all investigated for each prepared films. Nanocrystalline films with hexagonal structure and strong (100) and (002) preferred orientation were obtained. The maximum value of average grain size is (15.7) nm with 6% Co-doping concentration. The optical transmission spectra have shown that both pure and doped ZnO films were transparent in UV-Vis wavelength region. The energy band gap of 0% Co is about 3.28 eV and decrease to 3.2 eV after 4% doping. The excellent-estimated structure, the optical results are accomplished in doped ZnO film with (4 and 6) % Co.

The excitation energies for both the positive and negative parities of 90Sr,90Y,92Nb and 92Zr isotopes have been calculated by applying nuclear shell model with in the 2d5/2,1g7/2, 2d3/2, 3s1/2 and 1h11/2 model space for neutrons in 90Sr and 92Zr nuclei, also the 2p1/2, 1g9/2 for proton and 2d5/2,3s1/2 for neutron specified as model space in 90Y nucleus. While, model space for 92Nb nucleus was comprised of 1g9/2 for proton and 2d5/2 for neutron. Modified surface delta interaction with Matlab program have been used to calculate the present theoretical results. The agreement between theoretical prediction and experiment values were good. we determine and confirm the angular momentum and parity of energy levels that are not determined and unconfirmed experimentally. In addition to that, new energy levels have been predicted for all the isotopes in this present work. This will add more information which increases the theoretical Knowledge for all isotopes with respect to energy levels.
