An.in.ubation.experimen.(Exp. 1) with three soils, two from Australia an. on. from n.rway, was carried out to in.estigate the fate of dissolved BorreGro(a lign.sulfon.te, produced by Borregaard Lign.Tech Compan., n.rway) at differen. con.en.ration.(0, 10 an. 100 mg C L-1) in.soil solution.. A rhizobox experimen.(Exp. 2) was also don. in.a n.rwegian.clay soil, mixed with four levels of BorreGro-carbon.BG-C) added(0, 2, 20 an. 200 mg BG-C kg-1) to test the impact of BorreGro on.root growth, rhizosphere chemistry(pH, metals an. dissolved organ.c carbon.DOC)) an. the composition.of phospholipid fatty acids(PLFAs). The BorreGro addition.in.reased the con.en.ration.of Mn.due to the high con.en.ration. in.BorreGro. The BorreGro addition.to soil had an.in.irect but sign.fican. impact on.the rhizosphere chemistry an. PLFAs. The lowest amoun.s of added BorreGro facilitated the DOC excretion.at plan. roots, an. thereby in.reased the bacterial an. fun.al biomass, likely as an.effect of in.reased Mn.solubility from BorreGro in.the root zon..

Curren. research in.icates that stress problems primarily could be con.eptualized as deficien.ies in.recovery an. recuperation.between.stress periods. Accordin.ly, in.erven.ion. should put more emphasis on.this aspect. A group based in.erven.ion.program focusin. exclusively on.recovery behavior in.everyday life was evaluated in.this quasi-experimen.al, waitin.-list con.rol group study, where the con.rol group was also treated in.a secon. phase. Thirty-two self-referred female subjects, con.iderin. themselves in.n.ed of treatmen. for stress related health problems, were available for an.lyzes. Fifteen.of these con.tituted the first phase treatmen. group (In.), while the remain.n. 17 subjects were placed on.waitin. list (WLC). Addin. a few late applican.s leaved 20 subjects later treated in.the secon. in.erven.ion.phase. Sign.fican. an. clin.cally mean.n.ful positive effects emerged in.the In.—compared to the WLC-group on.recovery behaviors, stress—an. recovery experien.es, as well as on.burn.ut symptoms, worry, an.iety an. depression. Secon.ary an.lyzes of all treated subjects in.icated that the positive chan.e the primary clin.cal en.poin. was predicted by the in.rease in.frequen.y of recovery behaviors an. by the decrease in.the worry level. Thus, the presen. in.erven.ion.model merits further research with more rigorous experimen.al design.as well as with follow-up assessmen.s.

Aim: To evaluate the effect of polychlorin.ted biphen.ls (PCB) an. vitamin.C on.ven.ral prostatic an.ioxidan. system in.adult male rats. Methods: A group of 20 adult male rats were admin.stered ip Aroclor 1254 in.corn.oil at a dose of 2 mg·kg-1·day-1 for 30 days. Ten.con.rol rats were admin.stered on.y the vehicle. After 30 days the treated rats were divided at ran.om in.o 2 sub-groups of 10 an.mals each. On. sub-group received vitamin.C at a dose of 500 mg·kg-1·day-1 for 10 days. The other group was main.ain.d as Aroclor 1254 con.rol. Twen.y-four hours after the last treatmen. the rats were killed by decapitation. Ven.ral prostatic homogen.te was prepared an. used for the estimation.of en.ymatic an.ioxidan.s, in.ludin. superoxide dismutase (SOD), catalase (CAT) an. glutathion.-S-tran.ferase (GST) an. hydrogen.peroxide (H2O2), lipid peroxidation.(LPO) an. prostatic acid phosphatase. The serum levels of total T3, total T4, TSH, testosteron. an. estradiol were also assayed. Results: The body weight an. ven.ral prostatic weight were reduced in.PCB treated rats. The activities of SOD, CAT, GST an. acid phosphatase were decreased while the levels of H2O2 an. lipid peroxidation.were in.reased in.the ven.ral prostate of PCB treated rats. Admin.stration.of vitamin.C restored these parameters. Serum levels of thyroid hormon.s, estradiol an. testosteron. were decreased in.PCB treated an.mals. Admin.stration.of vitamin.C restored the thyroid hormon. levels. Con.lusion. PCB in.uces oxidative stress an. decreases the an.ioxidan. en.ymes in.the ven.ral prostate of adult male rats; the effects could be reversed by the admin.stration.of vitamin.C.

Two mean.field poten.ials, Woods-Saxon.an. Skyrme based poten.ials, are used to calculate the en.rgies of low-lyin. on.-quasiparticle states. The spectra of the low-lyin. states an. the α-decay spectra of n.clei belon.in. to the α-decay chain. of ^285Fl an. ^291,293Lv are calculated an. compared with the available experimen.al data. Depen.en.e of the splittin. of the pseudospin.doublets an. of the en.rgies of the un.que parity n.utron.on.-quasiparticle states on.the mean.field poten.ial are discussed. As shown. the α-decay spectra could be differen. in.the α-decay chain.an. at the direct production.of the n.cleus in.a fusion.reaction.

北方沼泽地水位下降对全球气候变暖的影响

自从最后一次冰川消退以来,北方沼泽地(3.46亿hm^2)积存了300～500Pg碳。这些沼泽地在分离二氧化碳(CO_2)的同时,释放了相当数量的甲烷(CH_4)到大气中。正如对高纬地区预报的那样,如果夏季变得更热、更干,未来沼泽地温室气体的平衡将发生变化,随之而来的CH_4排放将减少,而CO_2和n.2O的排放将增加。北部沼泽地水位下降预计将增强温室效应的影响。我们分别在不同营养水平的未排水和排水的沼泽地测量了碳循环的组分,并把这些结果归纳成一个简单的辐射强迫因子,用以评价水位下降对大气的综合影响。在对存于土壤和树木中的碳以及为经营森林而排水引起的水位下降后CO_2、CH_4和n.2O的通量的变化作出测量的基础上,我们提出一个假设,即由气候变化引发的干旱趋势将减弱北方沼泽地对总辐射强迫的影响,这一影响在100年内约为0.1W/m^2。CH_4排放的减少,沼泽地碳储量的微小变化和树木生物量储存的增加都将导致这一变化。
