This study is an example of applying the Normalized Full Gradient (NFG) method to an archeological site to determine the depth and location of structures that cause magnetic anomalies at the archeological site. One of the parameters that affects the shape and size of the magnetic anomaly is the depth of the source causing the anomaly. For this reason, it is important to correctly determine the location of the source. One of the methods of determining the depth of the structure using magnetic field data is the NFG technique. When using the downward analytical continuation, bias occurs due to the transition of the depth of mass, which is invalidated by this method. The NFG technique has been tested on anomalies caused by prismatic synthetic models. Test studies with synthetic models using the NFG technique have yielded satisfactory results. Based on these results, the NFG technique was applied to the real magnetic anomaly collected from the ancient city of Sapinuwa. The results were compared with the building remains found during the proposed excavations. The results obtained were satisfactory..

The condensation of compound 1 in presence of sodium hydroxide gave 3-((1Hbenzo[d][1,2,3]triazole-1-yl)methyl)-4- phenylethyl -1H-1,2,4-triazole-5(4H)-thione (BPT). Theoretical calculations of BPT have been studied. The 6-311G+ (d,p) basis set was used for the DFT computations. The calculated spectra matched up with what was observed; hence the findings were confirmed. The same theoretical calculation procedure was used to examine BPT's LUMO, HOMO, and other associated energy values. To find out whether solute-solvent interactions were peculiar to BPT, the Catalán–Kamlet–Taft solvent parameter was used. Molecular docking studies were performed and identified the active sites of BPT with four anti-microbial receptors like Aspergillus niger (3EQA), Hordeum vulgare (1CNS), and Candida Albicans (4HOE) Streptomyces sp. (1CHK).

In this context, they lead them to review their costs. When the cost items are analyzed, the most critical point that will give an advantage to companies in terms of cost is that companies healthily manage their inventory. Inventory management is of vital importance as the companies have a significant percentage in terms of cost and ensure that the customer demands are met in a timely and sufficient manner. This study focuses on the problems of the company's inventory control decisions that ensure balanced and minimum costs through effective inventory management. In this study, one-year data on demand, consumption, and inventory of a company that uses traditional methods including semi-finished products are considered. Since the demand is not known precisely and it is probabilistic, we apply the (R, S) inventory control model. We use simulation as a stochastic methodology to determine the inventory level of the construction materials manufacturing company under consideration. As a result of the study, after comparing the actual data in the current system with the developed model we apply, it is observed that the cost reduction and its use provided additional benefits to the company.

In this study, time-dependent settlement and three-dimensional (3D) seismic analyses of a historical stone bridge were investigated using the 3D discrete element modeling technique. For the settlement and seismic analyses, the historical single-span Çüngüş bridge which was built in the 18th century in Diyarbakır,Türkiye by Ottoman Empire was used. Since Diyarbakır is in a dangerous zone according to the Türkiye seismic map, the examination of this structure is very critical for the history of Türkiye. The 3D model of the bridge was created using the FLAC3D program based on the finite-difference method and all the stone elements in the historical bridge were modeled separately as blocks. Special interaction elements were defined between the discretely modeled stones. For settlement creep analyses, the Burger-creep material model, which was not used for the creep behavior of historical buildings in the past, was utilized. Firstly, the 500year long-term creep behavior of the bridge was examined by considering the fix boundary condition and full reservoir condition. According to the creep analyses, it was seen that the most deformation and failure section of the bridge is the arch section. Then, for the seismic analyses of the bridge, free-field and quiet nonreflecting boundary conditions were defined in the model. Furthermore, hysteresis damping coefficients were taken into account in seismic analyses with the help of special FLAC3D code. 10 different earthquakes were considered for the seismic analyses. According to the earthquake analyses, the earthquake behavior of the Çüngüş historical bridge was assessed by considering the full reservoir condition and it was understood that the 2023 Kahramanmaraş, Hatay, Malatya, Gaziantep earthquakes significantly changed the seismic safety behavior of Çüngüş single-span historical bridge.
