Signals In The Ionosphere Ahead Of Tsunami Arrival, Svetlana Riabova, Sergey Shalimov

Turkish Journal of Earth Sciences

We consider the impact of the tsunami propagating after the earthquake in Tohoku on the ionosphere according to measurements from the Hawaiian Islands, i.e., at a fairly large distance from the epicenter of the earthquake. These measurements, taken at a tidal tsunami monitoring station, at a magnetometric station, and by GPS, were used to record the arrival of the tsunami. We experimentally establish that the arrival of atmospheric waves generated by the tsunami significantly advanced the arrival of sea waves at the observation point, and this advance from one source was recorded in both the lower and upper ionosphere. Attention …

Possible Fluid Contributions From Active Faults To Mercury Distribution In Surface Sediments Of The Gemlik Gulf And Health Risk Assessment, Erol Sari, M. Namik Çağatay, Tuğçe Nagi̇han Arslan Kaya, Zeynep Çeti̇n, Nuray Çağlar

Turkish Journal of Earth Sciences

The Gemlik Gulf, located in the eastern part of the Sea of Marmara (Türkiye), is recognized as a relatively contaminated marine environment, influenced by a variety of natural and anthropogenic inputs. A comprehensive geochemical study was performed to examine the distribution of total mercury (THg) in surface sediments and to elucidate the possible sources contributing to its accumulation. The analysis revealed that THg concentrations ranged from 485 to 6486 ng/g, with all measured values substantially exceeding the average shale background concentration of 400 ng/g, indicating significant enrichment. According to sediment quality guidelines, none of the samples exceeded the effects range …

Paleoecology Of Loftusia Species (Large Benthic Foraminifera) In The Zagros Basin, North Of The Neotethys, Hossein Ghanbarloo, Amrollah Safari

Turkish Journal of Earth Sciences

Paleoecological analyses based on the wall structure of the genus Loftusia were carried out in the Maastrichtian deposits of seven outcrops of the Zagros Basin. Two types of particles are present within the wall structure: (1) tiny fossil grains and (2) detrital grains. Tiny fossil grains consist of smaller foraminifera and other small microorganism tests. Foraminiferal tests are associated with miliolid, textulariid, and rotaliid forms. Detrital grains include intraclasts and extraclasts. The presence of different particles in the test wall of this genus and the abundance of this genus in nutrient-rich conditions indicate that Loftusia are probably opportunistic foraminifera. This …

Turkish Journal of Earth Sciences

The Kaladgi Basin of the Dharwar Craton, southeast India, hosts Proterozoic unconformity-related uranium (U) mineralization controlled by faulted contacts between Archean basement and Proterozoic cover sediments. To understand the ore-forming processes, 25 core samples from the Cave Temple Arenite were analyzed using whole-rock geochemistry and fluid inclusion microthermometry. U concentrations reach up to 0.13% U3O8 in the basal arenite and lower conglomerate, whereas the basement schist records only 0.0017% U. Whole-rock data reveal high SiO2 contents (72–97 wt.%), variable Al2O3 (0.4–12.9 wt.%), and enrichments in U (0.38–6.63 ppm), Th (1.5–13.7 ppm), and trace elements such as Cu, Pb, and Ni …

Optimization Of Methane Production From Poultry Slaughterhouse Wastewater With Hydraulic Retention Time And Biochar Addition Using Response Surface Methodology, Juniarti Manova Hasibuan, Rita Purwasih, Bambang Haryanto, Dessy Ariyanti, Alfian Destomo, Agung Purnomoadi, Sutaryo Sutaryo

Baghdad Science Journal

Processing poultry slaughterhouse wastewater as a biogas substrate is a sustainable solution. The current study aimed to optimize methane production from poultry slaughterhouse wastewater at various hydraulic retention times, biochar addition levels, and biochar addition types. Optimization of the anaerobic digestion process was determined through response surface methodology with central composite design. The input variables were hydraulic retention times (10, 20, and 30 days), biochar levels (5, 10, and 15 g/L), and biochar types (chicken litter and rice straw). Meanwhile, the response variable was methane production. The results revealed that the resulting central composite design model was significant (p < 0.05) with an R-squared of 0.94, indicating a high model suitability. The analysis of variance showed that hydraulic retention times, biochar levels, and biochar types significantly affected methane production (p < 0.05). Based on optimization, the highest methane production was achieved at a 30-day hydraulic retention times, a biochar level of 15 g/L, and a biochar type of rice straw, which was 473.00 mL/g volatile solid. These results emphasize the importance of determining the correct hydraulic retention times and biochar addition (level and type) to optimize methane production.

Supporting Multilingual Learners Through Culturally Responsive Practices, Betsy Twedell

Graduate Teacher Education

This literature review examined how educational leaders can implement culturally responsive practices to support multilingual learners, improve academic achievement, encourage a sense of belonging, and advance equitable educational outcomes. A total of sixteen qualitative, quantitative, and mixed-methods studies were reviewed, along with two conceptual studies that provided additional guidance. Three recurring themes emerged: culturally and linguistically responsive practices, professional development, and Multi-Tiered Systems of Supports (MTSS). The research suggested that multilingual learners were best supported when educators viewed students’ languages, cultures, identities, and lived experiences as academic assets and integrated these resources into instruction. Findings also showed that professional development …

Surface Wave Propagation At The Interface Between An Inviscid Liquid Layer And A Rotating Micropolar Elastic Solid With Stretch, Somaiah Kamidi, Narsimharao Kandula, Venkateswara Rao Burugu, Gaddam Rajkumar, Srinivas Remidi

Baghdad Science Journal

This article investigates the impact of angular rotation on surface-wave propagation at the interface between an inviscid liquid layer and a rotating micropolar elastic solid with stretch. The surface-wave secular equation is obtained analytically using the plane-harmonic solution method after the mathematical model has been developed. It is noticed that for symmetric modes of surface waves, the liquid effects and the micro-stretch do not manifest simultaneously. Using MATLAB software, the impacts of the solid's angular rotation and the liquid layer's thickness on the symmetric mode of surface waves are illustrated for a specific model. The velocity of surface waves at …

Approximation Of Bi-Continuous Semigroups In The Trotter-Kato Framework: Application To Diffusion Equations With Non-Local Boundary Conditions, Abdulhameed Qahtan Abbood Altai

Baghdad Science Journal

This study develops and practically reformulates the Trotter–Kato theorem for the approximation of bi-continuous semigroups defined on Banach spaces with weaker locally convex Hausdorff topologies. This method extends the Trotter–Kato framework to semigroups with weak continuity by moving the analysis from the classical norm topology to a weaker topology. Equivalence and approximation conditions are derived without requiring explicit computation of resolvents, replacing them with T-stability and T-consistency properties. This new reformulation of the Trotter–Kato theorem provides a direct method for establishing convergence between approximating and limit semigroups, thereby simplifying both theoretical proofs and numerical analysis. The suggested framework …

Structural And Hamiltonian Properties Of The N–Array Unit Graphs Over Finite Rings, Puguh Wahyu Prasetyo, Muhammad Ardiyansyah, Joe Repka

Baghdad Science Journal

Consider a finite ring R, and let U( R ) denote the set of all its unit elements. The unit graph G_R of R is defined as follows: the vertex set V( G_R ) consists of all elements of R. Two distinct elements a,\ b∈ \ G_R are adjacent if and only if a + b∈ U( R ). Recent research has provided necessary and sufficient conditions for the unit graph G_R to have a Hamiltonian cycle. However, the property of Hamiltonicity under direct product constructions of rings has not been fully understood. This paper addresses this gap by studying …
