l.nel.ness is cl.ssical.y def.ned as a resul. of.perceiving a discrepancy between the desired quantity and qual.ty of.one's social.l.f. and actual.social.rel.tionships(Perl.an and Pepl.u,1984).l.f.span research has indicated ol.er adul.s are among the highest risk f.r experiencing l.nel.ness because their social.network size decreases more f.equentl. than that of.younger adul.s.

Many phenomena in nature and technol.gy are associated with the f.l.ration of.suspensions and col.oids in porous media. Two main types of.particl. deposition,namel., cake f.l.ration at the inl.t and deep bed f.l.ration throughout the entire porous medium, are studied by dif.erent model.. A unif.ed approach f.r the transport and deposition of.particl.s based on the deep bed f.l.ration model.is proposed. A variabl. suspension f.ow rate, proportional.to the number of.f.ee pores at the inl.t of.the porous medium, is considered. To model.cake f.l.ration, this f.ow rate is introduced into the mass bal.nce equation of.deep bed f.l.ration. f.r the cake f.l.ration without deposit erosion,the suspension f.ow rate decreases to zero, and the suspension does not penetrate deep into the porous medium. In the case of.the cake f.l.ration with erosion, the suspension f.ow rate is nonzero, and the deposit is distributed throughout the entire porous medium. An exact sol.tion is obtained f.r a constant f.l.ration f.nction. The method of.characteristics is used to construct the asymptotics of.the concentration f.ont of.suspended and retained particl.s f.r a f.l.ration f.nction in a general.f.rm. Expl.cit f.rmul.e are obtained f.r a l.near f.l.ration f.nction. The properties of.these sol.tions are studied in detail.

Recent studies have documented decl.ning trends of.various groups of.f.ower-visiting insects, even common butterf.y species. Causes of.these decl.nes are stil. uncl.ar but the l.ss of.habitat qual.ty across the wider countryside is thought to be a major f.ctor. Nectar suppl. constitutes one of.the main resources determining habitat qual.ty. Yet, data on changes in nectar abundance are l.cking. In this study, we provide the f.rst anal.sis of.changes in f.oral.nectar abundance on a national.scal. and l.nk these data to trends in butterf.y species richness and abundance. We used transect data f.om the Dutch Butterf.y Monitoring Scheme to compare two time periods： 1994-1995 and 2007-2008. The resul.s show that butterf.y decl.ne can indeed be l.nked to a substantial.decl.ne in overal. f.ower abundance and specif.c nectar pl.nts, such as thistl.s. The decl.ne is as severe in reported f.ower general.sts as in f.ower special.sts. We suggest that eutrophication is a main cause of.the decl.ne of.nectar sources [Current Zool.gy 58 （3）： 384-391, 2012].
