Research ArticleOpen accessPhrase in the titleCharacterization of Frequency Mode inside an Open Cavity for Different Shape RatioHallek Khouloud, Mourad Bouterra, Afif El Cafsi et al.A number of studies have referred to the existence of a vortex cell within an urban street canyon. The understanding of vortex dynamics or vorticity distribution is a such configuration is of great interest. This configuration was simulated by the interaction between a boundary layer and a cavity. Experimental characterization of the vortex structures evolution was developed by the technique … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 6,843 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsEffect of the Maximum Density Ratio Between Liquid and Vapor on Cavitating SimulationGuangjian Zhang, Weidong Shi, Ling Zhou, Desheng ZhangThe Filter-Based Model (FBM), which was built into CFX through CFX Expression Language (CEL) and a homogeneous cavitation model were employed to simulate cavitating flow around a 2D Clark-y hydrofoil. The effect of a maximum density ratio between liquid and vapor on sheet and cloud cavitating simulation was investigated. The results show that the maximum density ratio has a significant … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 21 Apr 2015 · 7,433 accessesView PDF Cite

Research ArticleOpen accessIn the abstractInheritance of Leaf Characters in Sweet Potato (Ipomoea batatas [L.] Lam.)Alfredo Morales, Dania RodríguezThis study aimed to establish foundational knowledge regarding the inheritance patterns of two foliar traits (leaf morphology and midrib pigmentation) in Ipomoea batatas. To overcome the challenges associated with discretely classifying color and shape frequencies, five morphometric descriptors were employed. Two of these parameters addressed leaf shape (Circularity and Aspect Ratio), while three characterized the color of the central vein … …American Journal of Agricultural and Biological Sciences, Vol. 21, Issue 1 · 3 Jul 2026 · 1,409 accessesView PDF Cite

Research ArticleOpen accessIn the abstractInvestigating the Effects of Some Key Psychological and Behavioral Theories Across a Spectrum of Research DisciplinesFelix Kabwe, Jackson PhiriThis study examines key psychological and behavioral theories to understand their impact on individual learning, decision-making, and behavior across various contexts. The study addresses the need for deeper insights into how these frameworks shape human behavior and their applications in diverse research disciplines. The frameworks explored include the Technology Acceptance Model (TAM), which forecasts technology adoption through constructs like perceived … …Current Research in Psychology, Vol. 11, Issue 1 · 3 Jan 2025 · 9,248 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAnalysis of Photosynthetic Pigment Content and Leaf Structure of Pteroceltis Tatarinowii Mutant with Yellow LeafYongchang Yu, Chen Lv, Min Liu, Tiantian ChenThe relationship betweenleaf variation characteristics and leaf structure characteristics of Pteroceltistatarinowii with yellow leaf was explored to provide a theoretical basisfor the breeding of other ornamental plants. In this study, the differences inpigment content, leaf structure, and chloroplast ultrastructure in leaves of Pteroceltistatarinowii mutant with yellow leaf 'Huiguang' and its original species'Lingyansi No. 1’ were studied. The results showed that … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 3 · 20 Sep 2022 · 5,598 accessesView PDF Cite

Research ArticleOpen accessIn the abstractStudy the Relationship between the Microstructure and Characteristics of Quinoa Starch by Compared with Common Cereal StarchesMenyue Jiao, Yumei Gao, Yiling TianThe amylose and amylopectin contents, viscoelastic properties, freeze-thaw stability and Scanning Electron Micrographs (SEM) of quinoa (Chenopodium quinoa Willd) were studied to explore the microstructural property relationships. Compared with wheat, corn, rice and waxy rice starches, quinoa starch had special characteristics connected to its unique microstructure. The high ratio of amylopectin to amylose (12.03) in quinoa starch affected its functional … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 4 · 17 Dec 2020 · 7,256 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSequence Stratigraphic Analysis from Well Logs of an X-Field, Niger Delta, NigeriaGodwin Omokenu Emujakporue, Alphonsus Joseph EyoThe sequence stratigraphic analysis of the area was studied using well log information in order to determine the lithostratigraphy, chronostratigraphy, possible reservoir sands, age and depositional environment of the study area for opportunities that will support exploration program. The depositional environment penetrated by the wells interpreted from log signatures gave three major facies association. The blocky and coarsening upward (funnel … …Current Research in Geoscience, Vol. 6, Issue 2 · 11 Jul 2016 · 13,975 accessesView PDF Cite

Research ArticleOpen accessIn the abstractWall Shear Stress Distribution in Patient Specific Coronary Artery BifurcationVahab Dehlaghi, Frank GijsenProblem statement: Atherogenesis is affected by hemodynamic parameters, such as wall shear stress and wall shear stress spatial gradient. These parameters are largely dependent on the geometry of arterial tree. Arterial bifurcations contain significant flow disturbances. Approach: The effects of branch angle and vessel diameter ratio at the bifurcations on the wall shear stress distribution in the coronary arterial tree … …American Journal of Applied Sciences, Vol. 7, Issue 9 · 30 Sep 2010 · 7,365 accessesView PDF Cite
