The effects of boron nitride/hydroxyapatite compounds on bone defects in osteoporotic rats
(Elsevier, 2023)This study investigated the effects of poly-(lactide-co-glycolide) (PLGA) scaffolds containing different concentrations of boron nitride (BN) and/or hydroxyapatite (HA) on bone defects in osteoporotic rats. The control ... -
Effects of WEDM and AWJ cutting methods on induction motor efficiency and total magnetic losses: Experimental design and response surface methodology
(Elsevier, 2023)In this study, the effect of cutting electrical steel laminations using abrasive water jet (AWJ) and wire electrical discharge machining (WEDM) techniques on 5.5 kW induction motor efficiency (MEfficiency) and total magnetic ... -
Polymer shape effect on damage evolution, internal defects and crack propagation of 3D-printed polymer-based cementitious backfill
(Elsevier, 2023)The strength property and damage mode of cementitious tailings backfill (CTB) are governed by its structural characteristics in the presence of the microstructure/internal defect effects. However, this correlation is still ... -
Analysing human error contribution to ship collision risk in congested waters under the evidential reasoning SPAR-H extended fault tree analysis
(Elsevier, 2023)Human error plays a crucial role in maritime transportation risk analysis, as a significant percentage of accidents, including collisions, groundings, capsizing, fires, and explosions, can be attributed to human errors. ... -
A new PWM technique for three-phase three-level neutral point clamped rectifier
(Springer, 2023)In this study, the aim is to evaluate three-phase (3 phi) three-level (3L) neutral point clamped AC/DC rectifier for high-power applications. The rectifier analysis has been simulated using a new modified carrier-based ... -
Analyzing of continuous and discontinuous contact problems of a functionally graded layer: theory of elasticity and finite element method
(Taylor & Francis Ltd., 2023)Contact mechanics analysis is crucial because such problems often arise in engineering practice. When examining contact mechanics, the material property of the contacting components is a crucially significant aspect. It ... -
Fast pyrolysis of tea bush, walnut shell, and pine cone mixture: Effect of pyrolysis parameters on pyrolysis crop yields
(MDPI, 2023)Liquid products obtained by the fast pyrolysis process applied to biomass can be used as chemical raw materials and liquid fuels. In this study, tea bush, walnut shell, and pine cone samples selected as biomass samples ... -
Polypropylene fiber effect on flexural strength, toughness, deflection, failure mode and microanalysis of cementitious backfills under three-point bending conditions
(MDPI, 2023)Cemented tailings backfill (CTB) is continually practiced in a large number of metallic mines for re-filling underground ore extraction areas. Re-filling these areas can boost the security of mining teams during construction. ... -
Hyper dual number matrices
(Maejo University, 2023)We study hyper dual numbers and hyper dual number matrices. Firstly, we give some basic properties of dual numbers and hyper dual numbers. Next, we investigate hyper dual number matrices using the properties of dual number ... -
Effect of a new type staggered pin fin configuration on flow boiling characteristics of micro-heat sinks
(Springer, 2023)Flow boiling in micro-pin fn structured heat sinks is an up-to-date thermal management technique. However, due to microsized fow passages, bubble blockage is a problem for this type of heat sinks, too. In addition, mixing ... -
A quantitative dynamic risk assessment for ship operation using the fuzzy FMEA: The case of ship berthing/unberthing operation
(Elsevier, 2023)Ships are exposed to static risks that stem from the nature of the operation as well as human, machine, and environmental factors and have a complex and multi-layered system that also contains dynamic risks. For this reason, ... -
Ag seed layer effects on SnO2 thin films for triboelectric devices
(Elsevier, 2023)Materials with triboelectric properties are critical to boosting the efficiency of triboelectric nanogenerators (TENG) by gathering power from waste force and mechanical movement. In this study, we explored tin-oxide (SnO2) ... -
Analyzing the mechano-bactericidal effect of nano-patterned surfaces by finite element method and verification with artificial neural networks
(Techno-Press, 2023)The study investigated the effect of geometric structures of nano-patterned surfaces, such as peak sharpness, height, width, aspect ratio, and spacing, on mechano-bactericidal properties. Here, in silico models were developed ... -
The heated debate over NAFLD renaming: An ongoing saga
(Kare Publishing, 2023)In 1980, Jurgen Ludwig, a pathologist at the Mayo Clinic, and colleagues formally described a disorder that involved the accumulation of fat in the liver, independent of significant alcohol consumption, or other secondary ... -
A comprehensive study on a medicinal and edible plant scorzonera incisa DC., discussing the natural limits of phytochemical profiling
(Wiley, 2023)Leaves of Scorzonera incisa DC. (Asteraceae) are eaten raw against diabetes and headache. Evaluation of medicinal, edible plants using profiling methods has become a common phenomenon. Petroleum ether (PE), ethyl acetate ... -
LBM curved boundary treatments for pulsatile flow on convective heat transfer and friction factor in corrugated channels
(Sage Publications, 2023)The present research investigates heat transfer and the flow characteristics of periodically corrugated wavy channels numerically under pulsatile flow conditions. The numerical method used here is Lattice Boltzmann Method ... -
Dynamics of a plant-herbivore model subject to allee effects with logistic growth of plant biomass
(World Stientific Publishing, 2023)This paper examines the relationship between herbivores and plants with a strong Allee effect. When the plant reaches a particular size, the herbivore attacks it. We use the logistic equation to model plant growth and ... -
Preoperative assessment of grade, T stage, and lymph node involvement: machine learning-based CT texture analysis in colon cancer
(Springer, 2023)Purpose To investigate whether texture analysis of primary colonic mass in preoperative abdominal computed tomography (CT) scans of patients diagnosed with colon cancer could predict tumor grade, T stage, and lymph node ... -
