In view of increas.ng lead pollution(Pb^(2+)) of coas.al waters. the compens.tory abilities.of holothurians.need to be as.es.ed. The goal of the work is.to clarify the functional and phenotypical differences.between two types.of phagocytes.P1 and P2) in eupentacta fraudatrix expos.d to Pb(NO_3)_2. It has.been s.own that 2 mg L^(-1) lead expos.re for 48 h increas.s.the number of P2 phagocytes.as.compared to P1 cells. does.not s.gnificantly affect cell viability in both P1 and P2 phagocyte fractions. and s.gnificantly enhances.chromatin condens.tion in P2 but not in P1 phagocytes. A lead concentration of 4 mg L^(-1) increas.s.the number of P1 phagocytes.compared to that of P2 type, and does.not change cell viability and chromatin condens.tion in P1 phagocytes. In the P2 type, it decreas.s.cell viability and does.not influence the level of apoptos.s. The protection agains. lead-induced apoptos.s.is.apparently mediated by the activities.of antioxidant enzymes. es.ecially glutathione s.trans.eras.. The differences.in labeling cell s.rface receptors.of P1 and P2 phagocytes.by plant lectins.als. indicate the s.ecific phenotypic properties.of thes. cells. The res.lts.clarify the potential and Gs.-dependent mechanis.s.of immune adaptation in holothurians.that have been s.ortly expos.d to lead at concentrations.clos. to the maximum environmentally relevant level in coas.al waters. Additionally, P1 and P2 phagocytes.are firs. s.own to have different functions.and phenotypes.during the res.ons. to lead, which indicates.the complexity of the phagocytic s.s.em in holothurians.and contributes.to unders.anding the immunity evolution.

The performance of La2-xCexCu1-yZnyO4 perovs.ites.as.catalys.s.for the high temperature water-gas.s.ift reaction （HT-WGs.） was.inves.igated. The catalys.s.were characterized by eDs.

The res.lts.s.owed that all the perovs.ites.exhibited the La2CuO4 orthorhombic s.ructure, s. the Pechini method is.s.itable for the preparation of pure perovs.ite. However, the La1.90Ce0.10CuO4 perovs.ite alone, when calcined at 350/700℃, als. s.owed a （La0.935Ce0.065）2CuO4 perovs.ite with tetragonal s.ruc- ture, which produced a s.rface area higher than the other perovs.ites. The perovs.ites.that exhibited the bes. catalytic performance were thos. calcined at 350/700℃ and, among thes., La1.90Ce0.10CuO4 was.outs.anding, probably becaus. of the high s.rface area as.ociated with the pres.nce of the （La0.935Ce0.065）2CuO4 perovs.ite with tetragonal s.ructure and orthorhombic La2CuO4 phas..

In this.paper, we s.udy modules.having only finitely many s.bmodules.over any ring which is.not neces.arily commutative. We try to unders.and how s.ch a module decompos.s.as.a direct s.m. We jus.ify that any module V having only finitely many s.bmodules.over any ring A is.an extens.on of a cyclic A-module by a finite A-module. Under s.me as.umptions.on A, s.ch as.commutativity of A, we prove that an A-module V has.finitely many s.bmodules.if and only if V can be written as.a direct s.m of a cyclic A-module having only finitely many A-s.bmodules.and a finite A-module.

We propos. a theoretical model of a nanoemitter for giga- and terahertz-range waves. The model is.bas.d on a peapod s.ructure compris.ng a carbon nanotube with chiral indices.（10, 10）. Three encaps.lated and partially polymerized fuUerene C60 molecules.and a pos.tively charged C60 fullerene are trapped ins.de the nanotube. The motion of the charged fullerene and the radiation frequency were controlled us.ng an external electric field. s.able terahertz radiation at a frequency of 0.36 THz was.produced at 300 K with an external electrical field of 10 V/μm. s.able radiation in the gigahertz range was.obs.rved at 50 K with an electric field below 10 V/m. A theoretical s.mulation was.performed us.ng the tight-binding molecular dynamics.method with a des.ription of the van der Waals.interaction by the Mors. potential. The s.s.em des.ribed by the theoretical model was.experimentally obs.rved.
