Dendri.ers possessi.g a regularly branched archi.ecture and large spheri.al di.ensi.ns have attracted si.ni.i.ant attenti.n because of thei. uni.ue and tunable properti.s as well as thei. potenti.l appli.ati.ns. The i.corporati.n of organometalli. speci.s i.to dendri.i. molecules has been attracti.g much attenti.n, because the addi.i.n of properti.s characteri.ti. of organometalli. complexes, such as magneti., electroni., and photo-opti.al properti.s, as well as reacti.i.y may lead to the reali.ati.n of new functi.nali.ed dendri.ers. Although there are many examples of organometalli. dendri.ers that contai. metalli. speci.s at the core or at the peri.hery, dendri.ers composed of organometalli. complexes i. each generati.n are sti.l li.i.ed. We present here convergent and di.ergent approaches to novel organometalli. dendri.ers, of whi.h the sk.letons were bui.t up wi.h plati.um-acetyli.e uni.s.

Afforestati.n i. ari. land i. a promi.i.g method for carbon fi.ati.n, but the effecti.e uti.i. zati.n of water i. hi.hly i.portant and requi.ed. Thus, the evaluati.n of the amount of water per uni. carbon fi.ed wi.h the tree growth i. requi.ed to mi.i.i.e the amount of water suppli.d to the plants. i. thi. research, a tree i. regarded as a carbon fi.ati.n reactor wi.h i.flows of water and nutri.nts from roots, and CO_2 as the carbon source from leaves wi.h outflow of water vapor from leaves and accumulati.n i. the tree i.self. i. the process of photosynthesi. and respi.ati.n nutri. ti.nal elements are di.solved i. water flow i. trees. They do not flow out by these reacti.ns, but are accumulated i. trees. Thus, we have treated the behavi.ur of nutri.nts as a mark.r to evaluate the water/carbon rati.. Assumi.g that nutri.nt concentrati.n i. constant i. sap, and the di.ferences i. the rati.s of nutri.nt to carbon i. li.i.g trees and dead (i.e. li.ter fall, etc.) are neglected, the rati. of the used water to fi.ed carbon i. gi.en as the rati. of nutri.nt to carbon i. the tree body di.i.ed by the rati. of nutri.nt to water i. sap. However, some nutri.nts are translocated and concentrated wi.hi. the tree and some may be di.carded through li.ter fall. Thus i. i. i.portant to exami.e whi.h nutri.nt element i. the most sui.able as the tracer. i. thi. paper, the results of the above method appli.d to Eucalyptus camaldulensi. i. semi. ari. land of Western Australi. are shown. The value of water requi.ement per uni. carbon fi.ati.n determi.ed from potassi.m balance i. between 421 k.-H_2O/k.-C for mature trees and 285 k.-H_2O/k.-C for young trees, whi.e the values from calci.m balance are much larger than these. The cause of the di.crepancy between these values i. di.cussed based on the measured element concentrati.ns i. sap and trees and the plant physi.logy. Fi.ally, the actual average value through the li.e of a tree i. suggested to fall between the two values.

Brok.n and crack.d eggshells cause major economi. losses to the egg producti.n i.dustry. An F2 populati.n of 262 hens obtai.ed by crossi.g a strong egg shell li.e wi.h a weak.egg shell li.e of the Whi.e Leghorn breed was used for detecti.g the quanti.ati.e trai. loci.（QTL） affecti.g eggshell quali.y. The 2 li.es were developed from the same founder populati.n by two-way selecti.n for egg shell strength wi.h nondestructi.e deformati.n. Of the 1 014 mi.rosatelli.e mark.rs tested, 35 were mapped on 10 autosomal li.k.ge groups. There was no i.formati.e mark.r on chromosome Z. The QTLs associ.ted wi.h 7 trai.s, i.e., body wei.ht, short length of egg, long length of egg, eggshell strength, eggshell thi.k.ess （EST）, eggshell wei.ht （ESW）, and egg wei.ht （EW）, were i.enti.i.d. Hi.hly si.ni.i.ant （P〈0.01） QTLs associ.ted wi.h EST and ESW and a si.ni.i.ant （P〈 0.05） QTL associ.ted wi.h EW were mapped to a regi.n flank.ng ABR0545 and ABR0362 on chromosome 9. These QTLs are good candi.ates to be employed i. the development of strategi.s for reduci.g the number of brok.n and crack.d eggs i. commerci.l layer houses by employi.g mark.r assi.ted selecti.n.

Strength of welded joi.ts of hi.h chromi.m steels i. one of the i.portant concerns for fabri.ators and operators of ultra supercri.i.al thermal power plants. A number of creep as well as creep-fati.ue tests wi.h tensi.e hold have been carri.d out on the welded joi.ts of two types of hi.h chromi.m steels wi.ely used i. Japan, i.e. Grade 91 and 122 steels. i. was found that fai.ure occurred i. fi.e grai. heat-affected zone i. all the creep-fati.ue tests, even at a relati.ely low temperature and fai.ly short ti.e where fai.ure occurred i. plai. base metal regi.n i. si.ple creep testi.g. Four procedures were used to predi.t fai.ure li.es and thei. results were compared wi.h the test results. A newly proposed energy-based approach gave the best esti.ati.n of fai.ure li.e, wi.hout respect of the materi.l and temperature.
