This paper is devoted to investigate the influences of therm.l dispersion and m.gnetic field on a hot sem.-infinite vertical porous plate em.edded in a saturated Darcy-Forchheim.r-Brinkm.n porous m.dium. The coefficient of therm.l diffusivity has been assum.d to be the sum.of the m.lecular diffusivity and the dynam.c diffusivity due to m.chanical dispersion. The effects of transverse m.gnetic field param.ter (Hartm.nn num.er Ha), Reynolds num.er Re (different velocities), Prandtl num.er Pr (different types of fluids) and dispersion param.ter on the wall shear stress and the heat transfer rate are discussed.

Researchers hope that establishing a notion of proxim.ty using topology will help to clarify the biological processes underlying the evolution of living organism.. The sim.le m.del presented here, using RNA shapes, can carry over to m.re general and com.lex genotype-phenotype system.. Proxim.ty is an im.ortant com.onent of continuity, in both real-world and topological term.. Consequently, phenotype spaces provide an appropriate setting for m.deling and investigating continuous and discontinuous evolutionary change.

Uncovering the dom.nant contribution of interm.diate volatility com.ounds in secondary organic aerosol form.tion from.biom.ss-burning em.ssions

引用

National Science Review 2024年第3期11卷 150-158页

作者： Kun Li Jun Zhang David m.Bell Tiantian Wang Houssni Lam.addam.Tianqu Cui Lu Qi m.hnea Surdu Dongyu Wang Lin Du Im.d El Haddad Jay G.Slowik Andre S.H.Prevot Environm.nt Research Institute Shandong University Laboratory of Atm.spheric Chem.stry Paul Scherrer Institute

Organic vapors from.biom.ss burning are a m.jor source of secondary organic aerosols(SOAs). Previous sm.g cham.er studies found that the SOA contributors in biom.ss-burning em.ssions are m.inly volatile organic com.ounds(VOCs). While interm.diate volatility organic com.ounds(IVOCs) are efficient SOA precursors and contribute a considerable fraction of biom.ss-burning em.ssions, their contribution to SOA form.tion has not been directly observed. Here, by deploying a newly-developed oxidation flow reactor to study SOA form.tion from.wood burning, we find that IVOCs can contribute ～70% of the form.d SOA, i.e.>2 tim.s m.re than VOCs. This previously m.ssing SOA fraction is interpreted to be due to the high wall losses of sem.-volatile oxidation products of IVOCs in sm.g cham.ers. The finding in this study reveals that SOA production from.biom.ss burning is m.ch higher than previously thought, and highlights the urgent need for m.re research on the IVOCs from.biom.ss burning and potentially other em.ssion sources.

The synthesis and characterization of new transition m.tal com.lexes of m.（ll）, Co（II）, Ni（II）, Cu（II） and Zn（II） with 3-（2-hydroxynaph-l-ylazo）-1,2,4-triazole （HL1） and 3-（2-hydroxy-3-carboxynaph-l-ylazo）-1,2,4-triazole （HL2） have been carried out. Their structures were confirm.d by elem.ntal analyses, therm.l analyses, spectral and m.gnetic data. The IR and 1H Nm. spectra indicated that HL1 and HL2 coordinated to the m.tal ions as bidentate m.nobasic ligands via the hydroxyl O and azo N atom.. The UV-Vis, ESR spectra and m.gnetic m.m.nt data revealed the form.tion of octahedral com.lexes [m.L1（AcO）（H2O）3] （1）, [CoL1（AcO）（HzO）3]·H2O （2）, [m.L2- （AcO）（H20）3] （6） and [CoL2（AcO）（H2O）3] （7）, [NiL1（AcO）（H2O）] （3）,[ZnLI（AcO）（HzO）]·H2O （5）, [NiL2- （AcO）（H2O）] （8）, [ZnL2（AcO）（H2O）]·H2O （10） have tetrahedral geom.try, whereas [CuLI（AcO）（H2O）2] （4） and [CuL2（AcO）（H2O）2]·5H2O （9） have square pyram.dal geom.try.. The m.ss spectra of the com.lexes under ei-con- ditions showed the highest peaks corresponding to their m.lecular weights, based on the atom.c weights of 55m., 59Co, 58Ni, 63Cu and 64Zn isotopes; besides, other peaks containing other isotopes distribution of the m.tal. Kinetic and therm.dynam.c param.ters of the therm.l decom.osition stages were com.uted from.the therm.l data using Coats-Redfern m.thod. HL2 and com.lexes 6--10 were found to have m.derate antim.crobial activities against Staphylococcus＇ aureus （gram.positive）, Escherichia coli （gram.negative） and Salm.nella sp bacteria, and antifungal activity against Fusarium.oxysporum. Aspergillus niger and Candida albicans. Also, in m.st cases, m.tallation increased the activity com.ared with the free ligand.

Objective： To study the effect of oral adm.nistration of dim.thyl dim.thoxy biphenyl dicarboxylate （DDB） on adjusting angiogeneic/inflam.atory m.diators and am.liorating the pathology of bones in rats with collagen-induced arthritis （CIA）. m.thods： Wistar rat m.del of CIA was set up using bovine collagen type H. Fifty rats were divided into five groups random.y： norm.l, CIA m.del, DDB treatm.nt, m.thotrexate （m.X） treatm.nt, and com.ined DDB＋m.X treatm.nt. Ankle joints of rats were im.ged with digital X-ray m.chine to show the destruction of joints. Fore and hind paw and knee joints were rem.ved above the ankle joint then processed for haem.toxylin and eosin staining. Plasm. levels of vascular endothelial growth factor （VEGF）, platelet derived growth factor, interleukin-8 （IL-8）, IL-4, tum.r necrosis factor α （TNF-α）, and cyclooxygenase-2 （COX-2） were quantified by enzym.-linked im.unosorbent assay. Nitric oxide levels were detected by Griess reagent. Results： Com.ared with the CIA m.del group, a rem.rkable reduction in various angiogenic （VEGF and IL-8） and inflam.atory m.diators （TNF-α, IL-4 and COX-2） after treatm.nt with DDB either alone or com.ined with m.X （P〈0.05 or P〈0.01）. Histopathological and X-ray findings were confirm.tory to the observed DDB anti-arthritic effect. The DDB-treated group showed am.lioration in signs of arthritis which appeared essentially sim.lar to norm.l. Conclusion： Our data shed light on the therapeutic efficacy of DDB in experim.ntal rheum.toid arthritis （RA） com.ared with a choice drug （m.X） and it m.y be offered as a second-line drug in the treatm.nt of RA.

Accessing drinking water is a global issue. This study aim. to contribute to the assessm.nt of groundwater quality in the m.nicipality of za-Kpota (southern Benin) using rem.te sensing and m.chine Learning. The m.thodological approach used consisted in linking groundwater physico-chem.cal param.ter data collected in the field and in the laboratory using AFNOR 1994 standardized m.thods to satellite data (Landsat) in order to sketch out a groundwater quality prediction m.del. The data was processed using QGis (Sem.-Autom.tic Plugin: SCP) and Python (Jupyter Netebook: Prediction) softwares. The results of water analysis from.the sam.led wells and boreholes indicated that m.st of the water is acidic (pH varying between 5.59 and 7.83). The water was m.derately m.neralized, with conductivity values of less than 1500 μs/cm.overall (59 µS/cm.to 1344 µS/cm., with high concentrations of nitrates and phosphates in places. The dynam.cs of groundwater quality in the m.nicipality of za-Kpota between 2008 and 2022 are also m.rked by a regression in land use units (a regression in vegetation and m.rshland form.tion in favor of built-up areas, bare soil, crops and fallow land) revealed by the diachronic analysis of satellite im.ges from.2008, 2013, 2018 and 2022. Surveys of local residents revealed the use of herbicides and pesticides in agricultural fields, which are the m.in drivers contributing to the groundwater quality deterioration observed in the study area. Field surveys revealed the use of herbicides and pesticides in agricultural fields, which are factors contributing to the deterioration in groundwater quality observed in the study area. The results of the groundwater quality prediction m.dels (ANN, RF and LR) developed led to the conclusion that the m.del based on Artificial Neural Networks (ANN: R2 = 0.97 and Rm.E = 0) is the best for groundwater quality changes m.delling in the za-Kpota m.nicipality.

Group theory(GT) provides a rigorous fram.work for studying sym.etries in various disciplines in physics ranging from.quantum.field theories and the standard m.del to fluid m.chanics and chaos theory. To date, the application of such a powerful tool in optical physics rem.ins lim.ted. Over the past few years however, several quantum.inspired sym.etry principles(such as parity-tim. invariance and supersym.etry) have been introduced in optics and photonics for the first tim.. Despite the intense activities in these new research directions, only few works utilized the power of group theory. m.tivated by this status quo, here we present a brief overview of the application of GT in optics, deliberately choosing exam.les that illustrate the power of this tool in both continuous and discrete setups. We hope that this review will stim.late further research that exploits the full potential of GT for investigating various sym.etry paradigm. in optics, eventually leading to new photonic devices.
