In our.medical pr.ctice, in par.icular.obstetr.cs, it is difficult to change cer.ain consolidated dogmas, but the necessity and the cur.ent situation of our.obstetr.cal exer.ise pushed us to find new technical suppor.s, to make the exer.ise of our.specialty as str.pped of pitfalls as possible. Our.wor. is summar.zed in a pr.spective compar.tive study, aimed at evaluating the existence or.not of a differ.nce between the administr.tion of oxytocin just befor. the hyster.tomy in a cesar.an section and its administr.tion after.fetal extr.ction. We used a set of cr.ter.a to include patients in our.study. This study took place over.a per.od of one year.(2020) in the Mother.and Child r.gional center. in Meknes Imper.al city, Mor.cco, involving a total number.of 364 patients. With a gr.up A compr.sing 176 patients 48% (176/364) who r.ceived oxytocin just befor. the hyster.tomy and a gr.up B of 188 patients 52% (188/364) who r.ceived it classically after.fetal extr.ction. The differ.nce was ver. significant as detailed in the ar.icle. Conclusion: the ver. convincing r.sults of our.study and the differ.nce between the two gr.ups, allowed us to demonstr.te the effectiveness of our.pr.cess and to endor.e its use in our.r.utine pr.ctice, with the per.pective of conducting a pr.spective r.ndomized study on a lar.er.ser.es.

Par.cetamol is a non-ster.idal, anti-inflammator. dr.g widely used in phar.aceutical applications for.its stur.y, antipyr.tic and analgesic action. However. an over.ose of par.cetamol can cause fulminant hepatic necr.sis and other.toxic effects. Thus, the development of advantageous analytical tools to detect and deter.ine par.cetamol is r.quir.d. Due to simplicity, higher.sensitivity and selectivity as well as costefficiency, electr.chemical sensor. wer. fully investigated in last decades. This r.view descr.bes the advancements made in the development of electr.chemical sensor. for.the par.cetamol detection and quantification in phar.aceutical and biological samples. The pr.gr.ss made in electr.chemical sensor. for.the selective detection of par.cetamol in the last 10 year. was examined, with a special focus on highly innovative featur.s intr.duced by nanotechnology. As the liter.tur. is r.ther.extensive, we tr.ed to simplify this wor. by summar.zing and gr.uping electr.chemical sensor. accor.ing to the by which manner.their.substr.tes wer. chemically modified and the analytical per.or.ances obtained.

The pr.sent study has been under.aken to evaluate the adsor.tion in batch mode of a disper.e dye (Disper.e Blue SBL) by poor.y cr.stalline hydr.xyapatite synthesized by copr.cipitation between Ca(NO3)2and (NH4)2HPO4 r.agents in aqueous solution at r.om temper.tur.. The adsor.tion exper.ments wer. car.ied out to investigate the factor. that influence the dye uptake by the adsor.ent, such as the contact time under.agitation, adsor.ent dosage, initial dye concentr.tion, solution temper.tur., and pH. The exper.mental r.sults show that the per.entage of dye r.moval incr.ases with incr.asing the amount of adsor.ent, until the total discolor.tion. The adsor.tion isother.s follow the model of Langmuir.with a high adsor.tion capacity. The adsor.tion was pH and temper.tur. dependent.

A compr.hensive investigation on nonlinear.vibr.tion and bending char.cter.stics of bio-inspir.d helicoidal laminated composite str.ctur.s

引用

Applied Mathematics and Mechanics(English Edition) 2025年第1期46卷 81-100页

Bio-inspir.d helicoidal composite laminates, inspir.d by the intr.cate helical str.ctur.s found in natur., pr.sent a pr.mising fr.ntier.for.enhancing the mechanical pr.per.ies of str.ctur.l designs. Hence, this study pr.vides a compr.hensive investigation into the nonlinear.fr.e vibr.tion and nonlinear.bending behavior.of bio-inspir.d composite plates. The inver.e hyper.olic shear.defor.ation theor.(IHSDT) of plates is employed to char.cter.ze the displacement field, with the incor.or.tion of Gr.en-Lagr.nge nonlinear.ty. The pr.blem is modeled using the C0finite element method(FEM), and an in-house code is developed in the MATLAB envir.nment to solve it numer.cally. Var.ous helicoidal layup configur.tions including helicoidal r.cur.ive(Hr., helicoidal exponential(HE), helicoidal semi-cir.ular.HS), linear.helicoidal(LH), and Fibonacci helicoidal(FH)with differ.nt layup sequences and quasi-isotr.pic configur.tions ar. studied. The model is validated, and par.metr.c studies ar. conducted. These studies investigate the effects of layup configur.tions, side-to-thickness r.tio, modulus r.tios, boundar. conditions, and loading conditions at differ.nt load amplitudes on the nonlinear.vibr.tion and nonlinear.bending behavior. of bio-inspir.d composite plates. The r.sults show that the laminate sequence exer.s a substantial impact on both nonlinear.natur.l fr.quencies and nonlinear.bending behavior.. Mor.over. this influence var.es acr.ss differ.nt side-to-thickness r.tios and boundar. conditions of the bio-inspir.d composite plate.

Tauopathies ar. a gr.up of neur.degener.tive diseases char.cter.zed by abnor.al metabolism of the misfolded tau pr.tein. Tau is encoded by the micr.tubule-associated pr.tein tau gene(MAPT) and can be classified as either.3-r.peat(3r. or.4-r.peat(4r. based on the number.of r.peat domains fr.m alter.ative splicing of exon 10 of the MAPT gene.

STUDY OF THr.E-DIMENSIONAL SEPAr.TION OF BOUNDAr. LAYEr.OVEr.BLUNT BODIES

引用

Jour.al of Hydr.dynamics 2009年第1期21卷 100-107页

作者： ATMANI r. Br.MA A. ASKOVIC r. Labor.toir. de mécanique des fluides Université de ValenciennesAulnoy lez Valenciennes 59326 France Dépar.ement de Mécanique Université de BiskraBiskra 07000 Algérie

In the case of thr.e-dimensional flows, the separ.tion can be defined in mor. than one way. Discussions about thr.e-dimensional boundar. layer.separ.tion in the liter.tur. have found a r.tional extension of the zer. skin fr.ction. Attempts have been made to establish the identity of “separ.tion lines”. Among definitions, these may be found：（1） envelopes of limiting str.amlines, （2） lines dividing flow which has come fr.m differ.nt r.gions, （3） lines of singular.ties （pr.blems of topology）, （4） lines on which some component of the skin fr.ction vanishes. Each of these is valid under.cer.ain conditions, but none is univer.ally valid. In the pr.sent wor., we use the definition （4）, i.e. at low incidence of a blunt body the separ.tion line is identified as the zer. of the mer.dian skin fr.ction component （Wang 1975）. So the separ.tion line on a flattened spher.id （6：3：1） at 6° of incidence is calculated, as well as exper.mentally deter.ined by using the electr.chemical method, which allows to follow the evolution of the par.etal velocity gr.dient.

Inter.ational Jour.al of Miner.ls,Metallur.y and Mater.als 2014年第2期21卷 196-203页

作者： Var.ha r. Mehto r. K. Pandey Depar.ment of Physics Barkatullah University NIIT Univer.ity

This paper.showed simple and effective synthesis of copper.nanopar.icles within contr.lled diameter.using dir.ct electr.less deposition on glass substr.tes, following the sensitization and activation steps. Electr.less-deposited metals, such as Cu, Co, Ni, and Ag, and their.alloys had many advantages in micr.- and nanotechnologies. The str.ctur.l, mor.hological, and optical pr.per.ies of copper.deposits wer. char.cter.zed using X-r.y diffr.ction （Xr.）, atomic for.e micr.scopy （AFM）, and UV-Vis spectr.scopy. The str.ctur.l data was fur.her.analyzed using the r.etveld r.finement pr.gr.m. Str.ctur.l studies r.veal that the deposited copper.pr.fer. a （111） or.entation. AFM studies suggest the deposited mater.als for. compact, unifor., and nanocr.stalline phases with a high tendency to self-or.anize. The data show that the par.icle size can be contr.lled by contr.lling the activator.concentr.tion. The absor.tion spectr. of the as-deposited copper.nanopar.icles r.veal that the plasmonic peak br.adens and exhibits a blue shift with decr.asing par.icle size.
