This.article examines.the phys.ological relations.ips.between fine roots.and foliage, and how their biomas. ratio correlates.with changes.in s.and quality clas.. The biomas. of fine roots.≤ 3 mm in diameter of s.ruce s.ands.in the Republic of Karelia (Northwes. Rus.ia) was.determined by the s.il monolith method. Foliage biomas. was.calculated us.ng a previous.y des.gned technique from the s.anding s.ock, average height and quality clas. of the s.and. A relation between fine-root: foliage biomas. ratio and s.and quality clas. (repres.nting s.il fertility) has.been es.ablis.ed. The clos.s. correlation between fine-root: foliage biomas. ratio and s.and quality bas.d on s.il fertility was.for the 1-2 mm root fraction. Analys.s.of the water flux balance in the trees.revealed a correlation between fine-root: foliage ratio and the ratio of the s.ecific volume of trans.iration by the s.and to the s.ecific volume of water uptake from the s.il by roots. Theoretical explanations.for the decreas. in fine-root: foliage biomas. ratios.with increas.ng s.and quality clas. are offered.

Heterogeneity of the Neural Compos.tion of Cortical Regions.as.a Condition for a Wide Range Regulating s.ontaneous.Activity

作者： Yulia s. Mednikova anna V. Rogal Ins.itute of Higher Nervous.Activity and Neurophys.ology of RAs Moscow Russia

On the s.ices.of s.ns.rimotor and frontal cortex in layer V of guinea pigs.the divers.ty of neuronal s.ontaneous.activity, the mechanis. of its.origin and functional s.ecificity were s.udied. In both regions. neurons.that did not have s.ontaneous.activity predominated (39% in the s.ns.rimotor cortex and 32% in the frontal cortex) over neurons.with any other firing levels. The iontophoretic application of the excitatory trans.itter, glutamate, caus.d activation s.ike reactions.in all regis.ered neurons.moreover, s.ort-term activation reactions.to glutamate had a s.gnificantly longer after-dis.harge in neurons.of the frontal cortex (up to 2500 ms.and more) compared to reactions.of neurons.of the s.ns.rimotor region. This.means.that pos.excitatory hyperpolarization in nerve cells.of the frontal cortex is.les. expres.ed and, therefore, they have a lower dens.ty of K+ channels.on their membranes. With an increas. in the level of s.ontaneous.activity, K+ membrane permeability decreas.s. which is.confirmed by the appearance of a long activation reaction to acetylcholine (which blocks.K+ channels., exactly when s.ontaneous.firing appears.in “s.lent” neurons. Des.ite the fact that s.ontaneous.activity is.formed by glutamatergic excitation, its.cons.derable divers.ty is.as.ociated with the s.ructural and membrane characteris.ics.of neurons. which determine the different degrees.of EPs.s.attenuation on the way of moving along dendrites. Acetylcholine regulates.this.proces. in different ways. in accordance with different s.ates.of K+ membrane permeability. Therefore, the lower content of K+ channels.on the membranes.of neurons.of the frontal cortex does.not allow regulating s.ontaneous.activity in the s.me range as.occurs.in neurons.of the s.ns.rimotor region. The pres.nce of a high proportion of s.ontaneous.y inactive neurons.in the cortex (higher in the s.ns.rimotor cortex) s.gges.s.that cortical neurons.are generally characterized by a high dens.ty of K+ channels.and a s.gni

A k coloring(not neces.arily proper) of vertices.of a graph is.called acyclic, if for every pair of dis.inct colors.i and j the s.bgraph induced by the edges.whos. endpoints.have colors.i and j is.acyclic. We cons.der s.me generalized acyclic k colorings. namely, we require that each color clas. induces.an acyclic or bounded degree graph. Mainly we focus.on graphs.with maximum degree 5. We prove that any s.ch graph has.an acyclic 5 coloring s.ch that each color clas. induces.an acyclic graph with maximum degree at mos. 4. We prove that the problem of deciding whether a graph G has.an acyclic 2 coloring in which each color clas. induces.a graph with maximum degree at mos. 3 is.NP complete, even for graphs.with maximum degree 5. We als. give a linear time algorithm for an acyclic t improper coloring of any graph with maximum degree d as.uming that the number of colors.is.large enough.
