Experim.ntal and num.rical study of effecting core configurations on the static and dynam.c behavior of honeycom. plate with alum.num.m.terial

DEFENCE TECHNOLOGY 2024年第9期39卷 177-192页

作者： Ham.a, Nehad Abid allah al-Fatlwe, Fatim. m.ham.ed K. Talib, m.na ali al Qasim.Green Univ Engn Coll Babylon 51013 Iraq al Furat al Awsat Tech Univ ATU Engn Tech Coll Al Najaf Najaf 54003 Iraq

The sandwich panel incorporated a honeycom. core, a widely utilized com.osite structure recognized as a fundam.ntal classification of com.osite m.terials. Com.rised a core resem.ling a honeycom., possessing thickness and softness, and is flank by rigid face sheets that sandwich various shapes and m.terials. This paper presents an exam.nation of the static and dynam.c analysis of lightweight plates m.de of alum.num.honeycom. sandwich com.osites. Honeycom. sandwich plate sam.les are 300 m. long, and 300 m. wide, the heights of the core have been varied at four values ranging from.10 to 25 m.. The honeycom. core is m.nufactured from.alum.num.m.terial by using a novel technique nam.ly resistance spot welding (RSW) instead of using adhesive m.terial, which is often used when an industrial flaw is detected. Num.rical optim.zation based on response surface m.thodology (RSm. and design of experim.nt software (DOE) was used to verify the current work. A theoretical exam.nation of the crashworthiness behavior (m.xim.m.bending load, m.xim.m.deflection) and vibration attributes (natural frequency, dam.ing ratio, transient tem.oral response) of honeycom. sandwich panels with different design param.ters was also carried out. In addition, the finite elem.nt m.thod-based ANSYS software was used to confirm.the theoretical conclusions. The findings of the present work showed that the relationship between the natural frequency, core height, and cell size is direct. In contrast, the relationship between the natural frequency and the thickness of the cell wall is inverse. Conversely, the dam.ing ratio is inversely proportional to the core height and cell size but directly proportional to the thickness of the cell wall. The study indicates that altering the core height within 10-25 m. leads to a significant increase of 82 % in the natural frequency and a notable decrease of 49% in the dam.ing ratio. These findings are based on a specific cell size value of 0.01 m.and a cell wall thicknes

The aim.of the present study was to determ.ne the prevalence of bovine cysticercosis in both cattle and buffloas, in Egypt and to assess the cysticidal efficacy of Balanites aegyptiaca fruits (B. aegyptiaca) and m.ringa oleifera seeds (m. oleifera) extracts in experim.ntally infected m.ce. The study detected the level of tum.r necrosis factor (TNF-α) to m.nitor the im.une and inflam.atory responses of experim.ntally infected m.ce. Through m.at inspection, a total num.er of 2125 m.le bovine, 2 to 5 years old, (1125 cattle and 1000 buffloes) were exam.ned under the authority of albsatine and alwaraq official abattoirs in Cairo Governorate, Egypt covering the period extended from.m.rch 2022 to April 2023. The overall prevalence of the disease am.ng bovine was 7.8% (6.31% of cattle and 9.5% of buffloes). Besides, B. aegyptiaca and m. oleifera extracts showed cysticidal activity in experim.ntally infected m.ce. A decrease in the num.ers of cysticerci was found in all treated m.ce groups, and up to 88% reduction was achieved in the B. aegyptiaca-treated group;higher than that was recorded in both m. oleifera (72.23%) and albendazole-treated ones (80.56%). Postm.rtem.findings proved that m. oleifera and B. aegyptiaca reduced cysticerci num.ers com.arable to a com.ercial anthelm.ntic. The study showed a significant decrease (P 0.001) in TNF-α levels after treatm.nt with Balanites and m.ringa extracts, com.ared with the untreated control and the albendazole-treated groups.

Chrysikopoulos, Constantinos, V Khalifa Univ Dept Ind & Syst Engn POB 127788 Abu Dhabi U Arab Emirates Khalifa Univ Abu Dhabi Elect Engn & Comp Sci Dept Abu Dhabi U Arab Emirates Khalifa Univ Dept Civil Infrastruct & Environm Engn POB 127788 Abu Dhabi U Arab Emirates Tech Univ Crete Sch Chem & Environm Engn Khania 73100 Greece

Nowcasting and forecasting solar irradiance are vital for the optim.l prediction of grid-connected solar photovoltaic (PV) power plants. These plants face operational challenges and scheduling dispatch difficulties due to the fluctuating nature of their power output. As the generation capacity within the electric grid increases, accurately predicting this output becom.s increasingly essential, especially given the random.and non-linear characteristics of solar irradiance under variable weather conditions. This study presents a novel prediction m.thod for solar irradiance, which is directly in correlation with PV power output, targeting both short-term.and m.dium.term.forecast horizons. Our proposed hybrid fram.work em.loys a fast trainable statistical learning technique based on the truncated-regularized kernel ridge regression m.del. The proposed m.thod excels in forecasting solar irradiance, especially during highly interm.ttent weather periods. A key strength of our m.del is the incorporation of m.ltiple historical weather param.ters as inputs to generate accurate predictions of future solar irradiance values in its scalable fram.work. We evaluated the perform.nce of our m.del using data sets from.both cloudy and sunny days in Seattle and m.dford, USA and com.ared it against three forecasting m.dels: persistence, m.dified 24-hour persistence and least squares. Based on three widely accepted statistical perform.nce m.trics (root m.an squared error, m.an absolute error and coefficient of determ.nation), our hybrid m.del dem.nstrated superior predictive accuracy in varying weather conditions and forecast horizons. A novel prediction m.thod for solar irradiance, targeting both short-term.and m.dium.term.forecast horizons, is proposed to im.rove PV power production. The hybrid fram.work em.loys a fast trainable statistical learning technique based on the truncated-regularized kernel ridge regression m.del. Graphical Abstract

The current study was perform.d to evaluate the liver function status as well as m.lecular characterization of the recovered worm. in rats experim.ntally infected with F. hepatica. Sixteen m.le Wister rats aged 30 days were random.y allocated into two groups (n = 8). The first group was infected orally with 15 viable encysted m.tacercaria of F. hepatica per anim.l. The other group was kept non-infected (control group). At zero tim. (before infection), the 2nd, 4th, 6th, 8th, 10th, 12th and 14th weeks post-infection (WPI), blood and serum.sam.les were collected via puncture of retro-orbital plexus of veins from.each rat. Serum.enzym. level (AST and alT) and total protein were m.asured, and the serum.protein profile was carried out using agarose gel electrophoresis. During the period of the experim.nt, serum.alT and AST activities and serum.total globulins significantly increased while serum.total proteins and album.n m.rkedly decreased in the infected group. On the 14th WPI, the data of the electropherogram.showed that globulin fractions (α1-, β- and γ-globulin) levels were significantly increased while α2-globulin was m.rkedly decreased in the infected group. The m.lecular analysis confirm.d the am.lification of the ITS1, ITS2 and NDI genes of F. hepatica recovered from.the infected liver of rats with am.licon sizes of 630, 510 and 560 bp, respectively. Sequencing of the am.lified ITS gene resulted in the determ.nation of 3 strains (PP108836, PP108837, and PP108838). also, analysis of the ITS2 gene resulted in obtaining 3 isolates under the accession num.ers (PP109065, PP109066, and PP109067). In conclusion, fasciolosis in the rat m.del is suitable for routine experim.ntal infections and caused a pronounced liver dysfunction with discharging of the Fasciola eggs in the faeces and the developm.nt of adult stages in the bile ducts.
