Regional and temporal evaluation of seismicity in the Vlora-Elbasani-Dibra Transversal Fault Zone, Albania
Characteristics of seismic activity along the Vlora- Lushnja-Elbasani-Dibra (V-L-E-D) Transversal Fault Zone are analyzed between 1964 and 2015. There are a total of 2814 events in the time interval 1964 and 2015 with Md1.7. This study is focused on the correlation of seismotectonic b-value, precursory quiescence Z-value, and interrelationships between some other seismicity parameters. The distribution of the relatively low b-value coincides with the tectonic compression field which acts along the V-L-E-D Transversal Fault Zone. The distribution of the relatively low b-value coincides with the tectonic compression field which acts along the V-L-E-D Transversal Fault Zone. Anomalously low b-value areas coincide more or less with the spatial distribution of M≥5.0 earthquakes and their known rupture extents. Temporal changes in b-value may be related to the stress variations in these times before and after the main events. The lowest Z-values show that the variations in seismic activity rate are not significant, and the highest Z-values demonstrate a decrease in seismicity rate. In the Z-value maps for all parts of the V-L-E-D, three areas exhibit significant seismic quiescence: centered at 41.00°N-19.78°E (region A, around Lushnja), 40.99°N-20.03°E (region B, in the Cerriku), 40.81°N-19.86°E (region C, including Kucova). In addition to these three significant areas, there are some small quiescence areas in different parts of the V-L-E-D
Oxide ionic conductivity properties of binary δ-(Bi2O3)1 - x (Yb2O3) x system
In this study, after doping ytterbium oxide (Yb2O3) to a-bismuth trioxide (a-Bi2O3) in the range of 9% n 20% in a series of different mole ratios, heat treatment was performed by applying a cascade temperature rise in the range of 700–790 C for 48 hours and new phases were obtained in the (Bi2O3)1 x(Yb2O3)x system. After 24 hours of heat treatment at 700 C and 750 C and 48 hours of heat treatment at 790 C, mixtures containing 9–20 mol% Yb2O3 formed a face-centered cubic phase. With the help of X-ray diffraction (XRD), the crystal systems and lattice parameters of the solid solutions were obtained and their characterization was carried out. The surfaces of the solid solutions were detected by a scanning electron microscope (SEM). Thermal measurements were made by using a simultaneous DTA/TGA (differential thermal analysis/thermogravimetric analysis) system. The total conductivity (sT) in the d-Bi2O3 doped with Yb2O3 system was measured using the four-probe DC method
Prediction of strain limits via the marciniak-kuczynski model and a novel semi-empirical forming limit diagram model for dual-phase DP600 advanced high strength steel
The prediction capability of a forming limiting diagram (FLD) depends on how the yield strength and anisotropy coefficients evolve during the plastic deformation of sheet metals. The FLD predictions are carried out via the Marciniak-Kuczynski (M-K) criterion with anisotropic yield functions for DP600 steel of various thicknesses. Then, a novel semi-empirical FLD criterion is proposed, and prediction capabilities of the criterion are tested with different yield criteria. The results show that the yield functions are very sensitive to anisotropic evolution. Thus, while the FLD curves from the M-K model and the proposed model are not the same for each thickness, the proposed model has better prediction than the M-K model. © 2020 Journal of Mechanical Engineering.

Kounis syndrome associated with benzathine penicillin G use: A case report
AbstractKounis syndrome is a life-threatening medical condition that causes severe allergic reaction and acute coronary syndrome. Benzathine penicillin G is one of the most widely used antibiotics in clinical practice, but it can enhance both allergic and hypersensitivity complications. In this report, we describe the case of a 42-year-old man admitted to our hospital who presented with cryptic tonsillitis accompanied by angioneurotic edema, chest pain, and electrocardiographic variations. The patient was diagnosed with Kounis syndrome and treated with oral antihistamines and prednisolone. He was discharged following a complete recovery and regression of electrocardiographic abnormalities within 72 hours
Visual Aesthetics and Mathematics in Cinema: Comparative Content and Cultural Analysis of Harry Potter and the Philosopher’s Stone and The Conquest 1453
Films are meticulously crafted using visual aesthetic elements, where mathematics and geometry play pivotal roles. Camera angles, timing in editing, staging sequences, lens specifications, and lighting ratios, demonstrate the intricate relationship between cinema and mathematics. Specifically, the virtual projection of isosceles and equilateral triangles is utilized in object positioning before the camera. Additionally, forms such as circles, squares, and rectangles are frequently employed in stage design. Number combinations, sequential numbers, and patterns are also common techniques used to enhance visual aesthetics in films. Fundamental components such as oblique, horizontal, vertical, and parallel lines are instrumental in achieving visual appeal.
In our research, we investigate the properties of these components as they are discussed in scientific publications and their relevance to aesthetics. In this context, a comparative and quantitative analysis is conducted on 2001’s “Harry Potter and the Philosopher’s Stone” and the Turkish film “The Conquest 1453” (known as Fetih 1453 in Turkey). It is observed that “The Conquest 1453” employs excessive mathematical and geometric data, which somewhat diminishes the thematic strength of the film. In contrast, “Harry Potter and the Philosopher’s Stone” demonstrates a more balanced use of these elements
