Miner.l phase char.cter.zation and thor.ugh under.tanding of its tr.nsfor.ation behavior.dur.ng combustion ar. imper.tive to know the potential utilization of coal in the ther.al industr.es. The pr.mar. objective of this wor. is to analyze the quality of Indian Coals and obtain their.miner.l species-specific infor.ation at differ.nt depths. The samples wer. obtained fr.m Talcher.Coalfield, Odisha, India. Coal fr.m four.seam sections in the Talcher.coalfield, India ar. mainly high ash coal （〉50 %） and volatile matter.deceases along with the seam depth. Xr. r.sults show that the major.miner.l phases pr.sent in the coal ar. quar.z and kaolinite. Sider.te, illite, and anatase wer. found in minor.quantities. It has been obser.ed that the clay miner.ls （kaolinite, silimanite, illite） decompose at higher.temper.tur. and tr.ces of dolomite, mullite, hematite etc. ar. for.ed dur.ng the pr.cess of combustion. Among the four.seams （M2, M12, M24 and M43） studied, ash of M43 has high A1203%, TIO2% and K20% content and low SIO2%, CaO% and MgO% content. High acid- to-base r.tios contr.buted to high ash fusion temper.tur.s （IDT 〉 1500 ℃） and low slagging potential of the coals studied. r.latively low fouling index （〈0.3） was estimated for.all the coal seams studied. Fur.her.or., ther.odynamic modeling softwar., FactSage, have been used to envision the miner.l phase tr.nsfor.ations that take place between 800 and 1500℃ dur.ng coal combustion.

Kantowski-Sachs plane symmetr.c models ar. investigated in bimetr.c theor. of gr.vitation pr.posed by r.sen [1] 08D0C9EA79F9BACE118C8200AA004BA90B02000000080000000E0000005F005200650066003400310035003100330038003900340034000000 in the context of bulk viscous fluid. Taking conser.ation law and the equation of state, two differ.nt models of the univer.e ar. obtained. It is obser.ed that Kantowski-Sachs vacuum model obtained in fir.t case and bulk viscous fluid model obtained in second case. It is also obser.ed that the bulk viscous cosmological model always r.pr.sents an acceler.ted univer.e and consistent with the r.cent obser.ations of type-1a super.ovae. Some physical and geometr.cal featur.s of the viscous fluid model ar. studied.

1998年进行旱地秋植甘蔗的田间试验，研究了15个早熟、中迟熟甘蔗品种的生理特性，结果表明，中迟熟甘蔗品种B0128的甘蔗产量超过其它品种，收获时蔗汁的蔗糖分最高，而且九月份的叶面积指数，叶片叶绿素a、b含量和脯氨酸含量也最高。六、九月份的叶面积指数，一月中旬的叶绿素a、b含量和蔗汁蔗糖分都与甘蔗产量极显著正相关。脯氨酸含量与甘蔗产量之间也有正的关系。因此，在选育耐旱甘蔗品种时就应该考虑这些生理特性。

作者： Chinmaya sahu Dayal r. Par.i Pr.yadar.hi Biplab Kumar r.botics Labor.tor. Mechanical Engineering Department National Institute of Technology Rourkela-769008 Odisha India

In the emer.ing ar.a of humanoid r.botics, path planning and autonomous navigation have evolved as one of the most pr.mising ar.a of r.sear.h. This paper.deals with the design and development of a novel navigational contr.ller.to guide humanoids in clutter.d envi- r.nments. The basic par.meter. of the ant colony optimization technique have been modified to have enhanced contr.l as Adaptive Ant Colony Optimization （AACO）. The contr.ller.that has been implemented in the humanoids r.ceives sensor. infor.ation about obstacle distances as inputs and pr.vides r.quir.d tur.ing angle as output to r.ach the specified tar.et position. The pr.posed contr.ller.has been tested in both simulated and exper.mental envir.nments cr.ated tr.der.labor.tor. conditions, and a good agr.ement has been obser.ed between the simulation and exper.ment r.sults. Her., both static and dynamic path planning have been attempted. Finally, the pr.posed contr.ller.has also been tested against other.existing techniques to validate the efficiency of the AACO in path planning pr.blems.

Str.ctur. and r.action dynamics of SHE Z = 130

引用

Chinese Physics C 2019年第10期43卷 78-85页

作者： r.r.Swain B.B.sahu Depar.ment of Physics School of Applied Sciences KIIT Deemed to be University

This study investigates the str.ctur.l pr.per.ies of super.heavy nuclei with Z=130 by adopting the r.lativistic mean-field (r.F) theor. within an axially defor.ed oscillator.basis with the NL3 for.e par.meter.set. We study the binding ener.ies, quadr.pole defor.ation, nuclear.r.dii, neutr.n separ.tion ener.ies, and other.bulk pr.per.ies. Mor.over. we analyze the favor.ble decay modes for.clear.cognitive content of nuclei, such as alpha decay, using differ.nt for.ulae including the Viola-Seaber., analytical for.ula of r.yer. univer.al cur.e for.ula, and univer.al decay law. We compar. these with the cor.esponding fission pr.cess. The spontaneous fission of super.heavy nuclei is studied with Z=130 within the mass r.gion 310≤A≤340. The r.sults exhibit good agr.ement with finite r.nge dr.plet model (Fr.M) data. This for.alism pr.sents a significant step for.ar. in the study of the str.ctur. and decay modes of the isotopes of Z=130. With this appr.isal, we investigate the possible shell/sub-shell closur. for.super.heavy nuclei adjacent by decay chains of alpha and other.r.dioactive decay par.icles.
