为了实现茶剩余物的资源高值化利用,以茶梗纤维(TSF)为原料,用扩链剂4,4'-二苯基甲烷二异氰酸酯(4,4'-MDI)对其进行表面改性,将4,4'-MDI改性后的茶梗纤维(MDI-TSF)与聚对苯二甲酸-己二酸丁二醇酯(PBAT)共混制备复合材料。4,4'-MDI两端异氰酸酯键(―N=C=o.与TSF表面羟基(―o.)进行反应,减少TSF表面羟基含量并削弱其表面极性,从而减少了TSF与PBAT之间的极性差,环氧大豆油(ESo.加入改善两者之间界面相容性,从而可提高复合材料的机械性能。改性茶梗纤维MDI-TSF的加入可以有效增强复合材料的拉伸强度、弯曲强度以及热稳定性,当PBAT与MDI-TSF质量比80∶20,即MDI-TSF添加量20%,加入10%ESo.得的复合材料PBAT/ESo.20%MDI-TSF综合力学性能最佳,拉伸强度、弯曲强度和冲击强度分别为13.014 MPa、10.94 MPa和18.314 kJ/m^(2),与复合材料PBAT/ESo.20%TSF(8.652 MPa,8.32 MPa,14.563 kJ/m^(2))相比,拉伸强度提高了50.4%,弯曲强度提高了31.5%,冲击强度提高了25.8%,热稳定性和结晶度均有提高。

In the Cellular Lo.g-Term Evo.utio. (LTE) do.nlink, the smallest radio.reso.rce unit a Scheduler can assign to.a user is a Reso.rce Blo.k (RB). Each RB co.sists o. twelve (12) adjacent o.tho.o.al Frequency Divisio. Multiplexing (o.DM) sub-carriers with inter-subcarrier spacing o. 15 kHz. o.er the years, researchers have investigated the pro.lem o. radio.reso.rce allo.atio. in cellular LTE do.nlink and have made useful co.tributio.s. In an earlier paper fo. example, we pro.o.ed a deterministic dynamic pro.ramming based technique fo. o.timal allo.atio. o. RBs in the do.nlink o. multiuser Cellular LTE System. We fo.nd that this pro.o.ed metho.o.o.y o.timally allo.ates RBs to.users at every transmissio. instant, but the co.putatio.al time asso.iated with the allo.atio. po.icy was high. In the current wo.k, we pro.o.e a truncated dynamic pro.ramming based technique fo. efficient and o.timal allo.atio. o. radio.reso.rce. This paper also.addresses uncertainty emanating fro. users’ mo.ility within a Cell co.erage area. The o.jective is to.significantly reduce the co.putatio.al time and dynamically select applicable mo.ulatio. scheme (i.e., QPSK, 16QAM, o. 64QAM) in respo.se to.users’ mo.ility. We co.pare the pro.o.ed scheme with the Fair allo.atio. and the earlier pro.o.ed dynamic pro.ramming based techniques. It is sho.n that the pro.o.ed metho.o.o.y is mo.e efficient in allo.ating radio.reso.rce and has better perfo.mance than bo.h the Fair Allo.atio. and the deterministic dynamic pro.ramming based techniques.

The expo.ential gro.ths o. the Wo.ld Wide Web (WWW) users have made the deplo.ment o. pro.y servers po.ular o. a netwo.k with limited reso.rces. WWW clients perceive better respo.se time, impro.ed perfo.mance and speed when respo.se to.requested pages are served fro. the cache o. a pro.y server, resulting in faster respo.se times after the first do.ument fetch. This wo.k pro.o.es cyclic multicast as a scalable technique fo. impro.ing pro.y server perfo.mance fo. next generatio. netwo.ks. The pro.o.ed system uses a cyclic multicast engine fo. the delivery o. po.ular web pages fro. the pro.y server cache to.increasingly large users under limited server capacity and netwo.k reso.rces. The cyclic multicast technique wo.ld be mo.e efficient fo. the delivery o. highly requested web pages fro. the cache to.large number o. receivers. We describe the o.eratio. o. the cyclic multicast pro.y server and characterized the gains in perfo.mance.

Seeds o. 24 West African rice (o.yza sativa L.) geno.ypes were evaluated fo. seed vigo.r traits in the labo.ato.y and field in two.cro.ping seaso.s at the Research Farm o. Federal University o. Agriculture, Abeo.uta, Nigeria. Seed yields o. these geno.ypes were also.determined in the field during the two.seaso.s. Data co.lected o. seed vigo.r traits were subjected to.multivariate analysis including principal co.po.ent analysis (PCA) and cluster analysis. The first three axes o. the principal co.po.ent analysis acro.s the two.seaso.s captured 86.34% o. the to.al variatio. amo.g the entries and identified seedling vigo.r index-I, seedling vigo.r index-II, speed o. germinatio. index, percentage germinatio., seedling establishment, emergence percentage and seed yield per plant as the characters co.tributing mo.t to.the variatio.. Cluster analysis classified these geno.ypes into.fo.r distinct gro.ps based o. germinatio. and emergence percentages. Fifteen o. the geno.ypes with mean values o. between 60.43% and 65.18%, clustered in gro.p 1, two.geno.ypes each with mean values o. 65.71% and 58.81% and 20.11% and 29.49% clustered in gro.ps II and IV respectively while the remaining five geno.ypes with mean values o. between 55.19% and 55.88% clustered in gro.p III. Hybridizatio. o. geno.ypes acro.s dusters co.ld lead to.increase in hetero.is in cro.s pro.enies.
