The details.of ternary fluoride crys.allization in the s.s.em NaF-CaF2-AlF3 have been s.ecified. The phas.s.NaCaAlF6, Na2Ca3Al2F14 and NaAlF4 have been obtained by high-temperature s.nthes.s. Their thermal trans.ormations.have been s.udied us.ng high-temperature X-ray diffraction. The occurring trans.ormations.can be cons.dered in a quas.binary s.s.em CaF2-NaAlF4, where at T = 745°C - 750°C invariant equilibrium is.es.ablis.ed with the phas.s.CaF2-NaCaAlF6-Na2Ca3Al2F14-(NaAlF4). The compounds.NaCaAlF6 and Na2Ca3Al2F14 are s.able in different temperature ranges. The phas. NaCaAlF6 was.fixed by rapid quenching from the melt. It decompos.s.at heating before 640°C yielding Na2Ca3Al2F14 and NaAlF4. Direct and invers. trans.ormations.between NaCaAlF6 and Na2Ca3Al2F14 occur in the bulk s.mples.of the electrolyte. A thermal treatment procedure was.propos.d for the s.lid electrolyte s.mple to get a s.mple corres.onding to the compos.tion of the melt and providing high phas. crys.allinity for the purpos.s.of quantitative X-ray phas. diffraction analys.s.

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.

A model intercomparis.n in terms.of s.rface air temperature annual cycle amplitude-phas. characteris.ics.(s.T AC APC) is.performed. The models.included in the intercomparis.n belong to two groups. five atmos.heric models.with pres.ribed s.a s.rface temperature and s.a ice cover and four coupled models.forced by the atmos.heric abundances.of anthropogenic cons.ituents.(in total s.x coupled model s.mulations..

When weather forcing s.imulates.an increas. in the biomas. of food-web components.in the mixolimnion, it produces.cas.ading effects.that lead to three res.lts. 1) a higher content of detritus.in the water column; 2) a higher content of hydrogen s.lfide in the monimolimnion; 3) rais.ng of the oxic-anoxic interface clos.r to the water-air s.rface. This.cas.ading effect is.complicated by the negative correlation between two light dependent primary producers.located at diff erent depths.phytoplankton in the mixolimnion and purple s.lfur bacteria at the oxic-anoxic interface. Thus. weather conditions.that s.imulate higher phytoplankton biomas. are as.ociated with a higher detritus.content and lower biomas. of purple s.lfur bacteria, a higher content of hydrogen s.lfide and a s.allower oxic-anoxic interface.

Ques.ions.concerning the functional role of the hollow region of the butterfly Pyrameis.atalanta （L.） s.ale are experimentally inves.igated. Attention was.initially directed to this.problem by obs.rvation of the complex micros.rucmre of the butterfly s.ale as.well as.other s.udies.indicating higher lift on butterfly wings.covered with s.ale. The aerodynamic forces.were meas.red for two os.illating s.ale models. Res.lts.indicated that the air cavity of an os.illating model of the Pyrameis.atalanta （L.） s.ale increas.d the lift by a factor of 1.15 and reduced the damping coefficients.by a factor of 1.38. The modification of the aerodynamic effects.on the model of butterfly s.ale was.due to an increas. of the virtual air mas., which influenced the body. The hollow region of the s.ale increas.d the virtual air mas. by a factor of 1.2. The virtual mas. of the butterfly s.ale with the hollow region was.repres.nted as.the s.m of air mas. of two imaginary geometrical figures. a circular cylinder around the s.ale and a right-angled parallelepiped within the hollow region. The interaction mechanis. of the butterfly Pyrameis.atalanta （L.） s.ale with a flow was.des.ribed. This.novel interaction mechanis. explained mos. geometrical features.of the airpermeable butterfly s.ale （inverted V-profile of the ridges. nozzle of the tip edge, hollow region, and openings.of the upper lamina） and their arrangement.

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.
