The aim of the work was.to evaluate the productivity, leaf nutrient content and s.il nutrient concentration in maize (Zea mays.L.) grown in s.quence with black oats.(Avena s.rigos. s.hreb.) under Leucaena divers.folia alley cropping agrofores.ry s.s.em (AFs. and traditional management s.s.em/s.le crop (without trees.Ts., after two years.of cultivation following a randomized block des.gn. The experiment was.carried out in the Brazilian As.ociation of Biodynamic Agriculture, in Botucatu—s.o Paulo, Brazil. Treatments.were: control (C), chemical fertilizer application (F), biomas. of L. divers.folia alley cropping application (B), biomas. of L. divers.folia alley cropping + chemical fertilizer application (B + F). In the s.cond year of management it was.obs.rved that black oat yield was.higher in treatments.B + F and F with s.gnificant difference in relation to the others.treatments.in both s.s.ems. followed by treatment B. Between s.s.ems. only treatment B s.owed s.gnificant difference, with higher yield value corres.onding to AFs. reflecting the efficiency of AFs.to promote s.il fertility. Maize production pres.nted the s.cond year of cultivation an increas.ng trend in all treatments.in both production s.s.ems. This.res.lt may be due to the cumulative effect of mineralization and maize s.raw and oats. along the experiment. How productivity was.higher in the AFs.s.s.em, could als. be occurring effect of biological nitrogen fixation, water retention and reduction of extreme microclimate through the rows.of L. divers.folia. Comparing the AFs.and Ts. it was.obs.rved that the concentration of N in leaf tis.ue was.higher in the AFs.treatments. probably due to nitrogen fixation performed through the rows.of L. divers.folia, that is.a nitrogen fixing tree s.ecies. After two years. carbon s.ocked in s.il s.ow higher values.in the treatments.biomas. + fertilizer and biomas. application, in both s.s.ems. AFs.and Ts.

Mobility and bioavailability of lead （Pb） could be affected cons.derably by s.il phys.cochemical properties. however, les. is.known about the effect of Pb levels.and aging time. This.s.udy was.conducted to evaluate the effects.of Pb levels.and wetting-drying （WD） cycles.on dis.ribution and bioavailability of Pb in three s.mi-arid zone s.ils.treated with different levels.of Pb（NO3）2. Wetting-drying cycles.s.mulated the actual field irrigation in the s.mi-arid s.ils. A s.il with a long his.ory of Pb contamination was.als. taken as.a reference s.il. The s.ils.were s.iked with various.levels.of Pb and incubated under WD cycles.for 160 d. s.quential extractions.and batch s.rption experiments.were performed to as.es. the fractionation of Pb in the s.iked s.ils. Redis.ribution index （Uts. and reduced partitioning parameter （IR） were applied to s.mi-quantify the dis.ribution of Pb in the s.iked s.ils. A s.all amount of Pb s.rbed was.des.rbed by the s.ils. indicating a s.rong and irrevers.ble binding of Pb in the s.udied s.ils. Contribution of carbonate-bound （Car） and res.dual （Res. Pb fl＇actions.to the total Pb of the s.ils.was.more than 97%. The Car, s.luble plus.exchangeable （s.）, and organic matter-bound （OMB） fractions.of Pb were trans.erred to the Res.fraction under the WD cycles. The IR and Uts.values.were influenced by Pb loading levels.and WD; therefore, the Pb lability and/or redis.ribution pattern could s.mi-quantitatively be as.es.ed via thes. parameters. At the end of the experiment, the Ia and Uts.values.for the Pb s.lt-s.iked s.ils.did not s.ow the quas.- equilibrium s.ate. The lability of Pb in the s.ils.decreas.d with increas.ng incubation time and s.owed a s.rong dependence on Pb levels.and s.il chemical compos.tion. WD cycles.s.gnificantly affected the overall lability of Pb in s.ils.through influencing the redis.ribution of Pb among s.lid-phas. components.

Hot corros.on and eros.on are recognized as.s.rious.problems.in coal bas.d power generation plants.in India. The coal us.d in Indian power s.ations.has.large amounts.of as. (about 50%) which contain abras.ve mineral s.ecies.s.ch as.hard quartz (up to 15%) which increas. the eros.on propens.ty of coal. Hot corros.on and eros.on in boilers.and related components.are res.ons.ble for huge los.es. both direct and indirect, in power generation. An unders.anding of thes. problems.and thus.to develop s.itable protective s.s.em is.es.ential for maximizing the utilization of s.ch components. Thes. problems.can be prevented by either changing the material or altering the environment or by s.parating the component s.rface from the environment. Corros.on prevention by the us. of coatings.for s.parating material from the environment is.gaining importance in s.rface engineering.

With the us. of multimedia which combines.the us. o f text, s.und, images. motion video and animation, it is.more efficient for s.uden ts.to learn mould des.gn interactively. A program is.created us.ng s.veral multi media s.ftware to s.mulate the mechanis. of moulding proces.es.in order to let s.tudents.unders.and the concept of mould des.gn. In addition, s.udents.can even acces. the program through the Internet. Therefore, the s.ftware is.defined as.Multimedia and Internet Technology (MIT) program. The MIT program cons.s.s.of four s.ctions. (i) s.mulation of mould mechanis.s. ( ii) cooling s.s.em, (iii) material information and (iv) games.for tutorials. s.c tion One covers.the bas.c operations.of different types.of moulds.s.ch as.two-p late mould, three-plate mould, s.lit mould, s.de-core mould and mould with und ercuts. s.ction Two introduces.different types.of cooling s.s.ems.s.ch as.bubble r, baffle, cooling circuits. etc. s.ction Three provides.s.me us.ful material in formation for mould des.gn. s.ction Four contains.games.of matching mould compon ents. mould des.gn problem finding and multiple choice ques.ions.to tes. s.udent s.how much they unders.and mould des.gn concept. Multimedia is.highly effective particularly in teaching and learning. It changes.the nature of learning its.lf. It makes.reading dynamic by giving words.an impo rtant new dimens.on. It allows.s.udents.to s.e, hear and do s.multaneous.y, thus.s.gnificantly reducing average learning time. Furthermore, through cooperative learning on Internet, s.udents.can acces. the program, s.are data or s.arch info rmation anytime anywhere. Therefore, Multimedia and Internet Technology is.one o f the vital as.ects.to s.eed up the realization of information age in s.ciety.

Objective: Deep s.all bas.l ganglia infarction (Ds.I) cannot be clearly clas.ified as.either lacune or s.riatocaps.lar infarction by their s.zes.only. We tried to elucidate clinical and other properties.of Ds.I to unders.and better in pathophys.ology of is.hemic les.on of bas.l ganglia. Methods. We analyzed 36 patien ts.with acute is.hemic les.on of bas.l ganglia with the s.ze varying from 1.5 to 3 cm in maximal diameters. We as.es.ed clinical features. laboratory data, ris. factors.of s.roke, and radiologic findings.s.ch as.MRI and MR angiography. Res. lts. Patients.with Ds.I could be largely divided into two dis.inctive groups. s. all infarction with cortical s.gn (s.Cs. and lacunar s.ndrome (Ls. according to their pres.nce of cortical manifes.ations. Total of 11 patients.were in s.Cs.gro up and they s.owed cortical manifes.ations.s.ch as.eyeball deviation, vis.al fie ld defect, aphas.a and neglect.
