ECONOMIC EFFECTS OF EARTHQUAKES 1999 MARMARA/TÜRKİYE EARTHQUAKE CASE
No full textFrequent earthquakes are a reality of Türkiye. It is very important to be prepared for these earthquakes, take the necessary measure before the earthquake and to recover the losses quickly when an earthquake occurs. In this study, the literature on the economic effects of earthquakes is examined and the effects of earthquake on the Kocaeli province, the epicenter of the 1999 Marmara Earthquake, are analyzed. As an important indicator of the level of economic activity, the effects of the earthquake on the city's exports were examined with panel data regression covering the years 1996-2021 and 163 countries. The results of the regression analysis show that despite the big magnitude of the earthquake and the heavy losses, the economy of Kocaeli province recovered rapidly and returned to its export performance rapidly, even surpassing its previous performance in a short time
Investigation of the thermal-hydraulic properties of a L-footed spiral finned tube heat exchanger and derivation of new empirical correlations
No full textThe aim of this study is to investigate the thermal hydraulic properties of the l-footed spiral fin-and-tube heat exchanger and to derive empirical correlations giving the Colburn (j) factor and the Fanning (f) friction factor. In the cross-flow heat exchanger, the rows of tubes were arranged staggered in the direction of the air flow. Under constant water inlet volumetric flow rate (2.3 l/min) and ambient air conditions, experimental study was carried out for seven different water inlet temperatures (40 degrees C, 45 degrees C, 50 degrees C, 55 degrees C, 60 degrees C, 65 degrees C, 70 degrees C) and air inlet velocity (3.40 m/s, 4.20 m/s, 5.26 m/s, 5.83 m/s, 6.33 m/s, 7.02 m/s, 7.90 m/s). The temperature effectiveness-the number of transfer units (P-NTU) method was used to determine the overall heat transfer coefficient. The non-linear least squares method was used for regression analysis. Reynolds number (Re) ranged from 9043 to 21579. As a result of the study, average heat transfer, P-1 and P-2 temperature effectiveness, overall heat transfer coefficient (U), fin efficiency (eta(f)), total surface efficiency (eta(o)), heat transfer coefficient (h), Nusselt number (Nu), Colburn (j)-factor, pressure drop (triangle p) and Fanning (f)-friction factor values were obtained. Using experimental findings, air side Colburn (j) factor and Fanning (f) friction factor correlations were obtained. Dimensionless maximum temperature difference (DMTD) has been proposed as a new parameter to add the effect of water inlet temperature to the Reynolds number-Colburn (j) factor relationship. Adding DMTD to the Colburn (j) factor-Re number relationship increased the correlation coefficient (r) from 0.717 to 0.965
Generalized Fuzzy Subalgebras of Sheffer Stroke Hilbert Algebras
No full textThis paper introduces new generalized fuzzy subalgebras and investigates their important properties within the framework of Sheffer stroke Hilbert algebras. We characterize these generalized subalgebras through their level subsets and establish key properties that define their structure. The Sheffer stroke operation, known for its ability to construct logical systems independently of other operators, plays a central role in our study. Using fuzzy set theory, we adapt the traditional ideas of subalgebras to fit fuzzy contexts, giving a detailed look at (?, ? ?qm)-fuzzy subalgebras. Our results include necessary and sufficient conditions for a fuzzy set to qualify as such a subalgebra, along with theorems addressing their intersections, unions, and homomorphic invariance. This work contributes to the broader understanding of algebraic structures in fuzzy logic and their applications in logical systems. © 2025 Elsevier B.V., All rights reserved

Resistance of some lentil cultivars against the cowpea beetle, Callosobruchus maculatus (F.) (Coleoptera: Chrysomelidae)
No full textThe cowpea beetle, Callosobruchus maculatus (F.), is one of the detrimental insect pests of legume seeds in field and storage conditions. In the current study, the seeds of five lentil cultivars, Perkouz, Sana, Sepehr, Bileh-Savar, and Gachsaran, were evaluated for their resistance to C. maculatus based on life-table parameters, oviposition preference, and digestive function. The biochemical and physical features of studied cultivars were also evaluated to comprehend their potential correlations with examined pest parameters. In the free-choice experiment, the quantity of eggs deposited on Perkouz was highest, while it was lowest on Bileh-Savar. Developmental times on Bileh-Savar, Gachsaran, and Sepehr were longer than on Perkouz. The beetles fed with Bileh-Savar showed lowest net reproductive rate, intrinsic rate of population increase and finite rate of increase. Fourth-instar larvae exhibited lowest proteolytic and highest amylolytic activity on Bileh-Savar. Among the characteristics of lentil seeds, hardness index, moisture content, as well as starch and protein levels notably affect the population parameters of C. maculatus. Given the results of this investigation, Bileh-Savar is the most resistant cultivar for feeding and population increase of C. maculatus and can be considered in management strategies of this pest.University of Mohaghegh ArdabiliThis work received financial support from the University of Mohaghegh Ardabili which is greatly appreciated
In Vitro Evaluation of the Mechanical Properties of Posterior Adhesive Restorations Fabricated Using Three Different Techniques
No full textThis study evaluates the optical properties and mechanical durability of adhesive restorations fabricated using different techniques for the treatment of single-tooth loss in the posterior region after an aging process. Sixty extracted human teeth (thirty molars and thirty premolars) were restored using three different fabrication methods: 3D-printed resin restorations, fiber mesh-reinforced direct composite restorations, and indirect composite restorations. Color stability was assessed using a spectrophotometer, and fracture resistance was measured using a universal testing machine. Finite element stress analysis (FEA) was conducted to validate mechanical test results under simulated intraoral conditions. The fiber-reinforced composite group exhibited the highest fracture resistance (1057.91 MPa), while 3D-printed restorations showed the lowest (p < 0.05). Regarding color stability, the fiber-reinforced group demonstrated the highest Delta E-00 values (Delta E-00 = 1.71), differing significantly from the other groups, while the 3D-printed and indirect composite restorations showed no significant difference. Mechanical test results were consistent with FEA findings. These results indicate that fiber reinforcement enhances mechanical durability in high-load-bearing areas, while 3D-printed restorations may not yet be suitable for posterior regions. However, their potential use in anterior restorations, where occlusal forces are lower, warrants further investigation to improve material properties.Ege University Scientific Research Projects Coordination; [BAP/32594]This research was funded by Ege University Scientific Research Projects Coordination, grant number BAP/32594
Potential Impact of Parental Origin of Inheritance on the Clinical Presentation of Familial Partial Lipodystrophy Type 2 Syndrome
No full textContextFamilial partial lipodystrophy type 2 (FPLD2) is a rare autosomal dominant disorder caused by pathogenic variants in the LMNA gene. The influence of parental inheritance on clinical presentation has not been fully explored.ObjectiveTo investigate the influence of maternal versus paternal inheritance of LMNA variants on the clinical and metabolic phenotype of patients with FPLD2.Design, Patients, MeasurementsThis retrospective cohort study included 83 patients with FPLD2 from four different centres. Clinical, biochemical, and body composition data were analysed. Patients were grouped based on maternal (maternal inheritance group; n = 49) or paternal (paternal inheritance group; n = 34) inheritance of LMNA variants. Statistical comparisons were made between the groups.ResultsPatients in the maternal inheritance group had a younger current age (35 (33) vs. 48 (22) years, p = 0.042) and earlier diagnosis of lipodystrophy (22 (30) vs. 36 (25) years, p = 0.044) compared to those in the paternal inheritance group. Body fat percentages in the arms (23.8 (6.5) % vs. 21.0 (6.2) %, p = 0.034) and trunk (32.1 (10.3) % vs. 28.5 (6.1) %, p = 0.024) were higher in maternal inheritance group. Fatty liver disease (79% vs. 57%, p = 0.029) and pancreatitis (26% vs. 8%, p = 0.033) were more prevalent in paternal inheritance group.ConclusionParental lineage may influence the phenotype of FPLD2: patients with a maternally inherited LMNA variant tend to preserve more adipose tissue in the upper body, while those with a paternally inherited variant experience greater adipose tissue loss in that region, often associated with more severe metabolic complications. These findings highlight the importance of contemplating parental lineage as a relevant factor when evaluating the clinical presentation and management of patients with FPLD2.National Institute of Diabetes and Digestive and Kidney Diseases (Grant 2R01DK125513), and Dokuz Eylul University-Research Fund (Project Number TUI-2023-3126).; Caswell Diabetes Institute; Lipodystrophy Fund of the University of Michigan [2R01DK125513]; National Institute of Diabetes and Digestive and Kidney Diseases [TUI-2023-3126]; Dokuz Eylul University; University of PisaWe are grateful to our patients whose data are being presented.

Characterizing the diet of Atlantic bluefin tuna Thunnus thynnus across its spatial range: a metadata analysis spanning over three decades
No full textAtlantic bluefin tuna Thunnus thynnus (ABFT) are highly migratory predators that feed across diverse foraging habitats throughout their range. ABFT diet has been characterized regionally, but a broader analysis is needed to help inform ecosystem-based management of these economically and ecologically important predators, given their environmental and spatial plasticity. We conducted a metadata analysis using assembled diet data from 1985–2020 (n = 4997 total stomachs; 4046 non-empty stomachs) for ABFT (6–328 cm straight fork length, SFL) from 9 Longhurst Provinces (LPs). ABFT trophic ecology was characterized by exploring relationships between (1) diet composition (using classification trees), (2) total stomach content weight (using generalized additive models, GAMs), and (3) predator–prey size (using quantile regression and GAMs) and spatial, temporal, biological, and environmental variables. Diet composition primarily differed by sampling year, LP, and ABFT SFL. Diet over the Northwest Atlantic shelf was distinct due to the prevalence of Clupeidae. Temporal splits in this region were based on consumption of Ammodytidae and Ommastrephidae in the earliest and latest years of our data set, respectively. Diet composition for the other LPs primarily differed based on SFL, with smaller ABFT (<79 cm) mainly consuming engraulids and larger ABFT (?79 cm) consuming ommastrephids and paralepidids. Total stomach content weight and prey length increased asymptotically with ABFT SFL and varied in relation to environmental, sampling, and spatial variables. Quantifying diet composition by space and ontogeny is useful for developing improved food web models to better understand ecosystem effects of fisheries. Our metadata analysis also highlights future research priorities. © 2025 Elsevier B.V., All rights reserved
