Brea.t ca.cer is a.ma.or public hea.th problem beca.se of its incidence a.d morta.ity. Purpose: To esta.lish the epidemiologica. a.d clinica. cha.a.teristics of brea.t ca.cer seen a. the ra.iothera.y center a. the Ma.i Hospita. of Ba.a.o. Pa.ients a.d methods: It wa. a.retrospective, descriptive study of da.a.from pa.ients seen for brea.t ca.cer a. the Center of Ra.iothera.y of Ma.i Hospita. between a.ril 2014 a.d December 2016. The pa.a.eters studied were: a.e, sex, fa.ily history of brea.t ca.cer, menopa.sa. sta.us, pa.ity, brea.t tumor loca.ion, histologica. type, histologica. gra.e, ca.cer cla.sifica.ion sta.e. Results: 134 ca.es of brea.t ca.cer were collected, with a.frequency of 15%. The sex ra.io (H/F) of 0.007. The pa.ient’s mea. a.e wa. 47 ± 11 yea.s old. The most represented a.e groups were 33 - 47 yea.s old with 45.5% a.d 48 - 62 yea.s old with 39%. Three percent (3%) of pa.ients ha. a.fa.ily history of brea.t ca.cer. Fifty (50%) of the pa.ients were menopa.sa.. The ma.n clinica. signs found were : ma.ma.y nodules (98%), ma.todynia.(65%), nodes (67%). Inva.ive ducta. ca.cinoma. were found in 94% of pa.ients, followed by infiltra.ing lobula. ca.cinoma. with 3.7% a.d meta.la.tic ca.cinoma. with 1.7%.

The non-isotherma. decomposition kinetics of LiClO4 in flow N2 a.mosphere wa. studied. TG-DTa.curves show tha. the decomposition proceeded through two well-defined steps below 900℃, a.d the ma.s loss wa. in a.reement with the theoretica. va.ue. XRD profile demonstra.es tha. the product of the therma. decomposition a. 500℃ is LiCI. For the decomposition kinetics study, the a.tiva.ion energies ca.cula.ed with the Friedma. method were considered a. the initia. va.ues for non-linea. regression a.d were used for verifying the correctness of the fired models. The decomposition process wa. fitted by a.two-step consecutive rea.tion： extended Prout-Tompkins equa.ion[Bna. f（α） is （1-α）^nα^α] followed by a.lth order rea.tion（F1）. The a.tiva.ion energies were （215.6±0.2） a.d （251.6±3.6） kJ/mol, respectively. The exponentia.s n a.d a.for Bna.rea.tion were （0.25±0.05） a.d （0.795±0.005）, respectively. The rea.tion types a.d a.tiva.ion energies were in a.reement with those obta.ned from the isotherma. method, but the exponentia.s were optimized for better firing a.d prediction.

本文以中国在几内亚矿业领域的投资问题为重点探讨了中非关系。在查阅现有文献的基础上,分析并强调了不同学者提出的中国在几内亚的矿业部门进行重点投资的原因。这项研究既考察了中国在几内亚投资的历史因素,也强调了当前的发展状况,同时,还着重探讨了中国对几内亚矿业投资产生的影响,尤其是对几内亚的社会和经济发展产生的影响。此外,本文进一步研究了几内亚人对于中国投资的看法。研究发现,在几内亚矿业投资的大多数中国公司都是国有企业,不但在金融方面得到了本国政府的全力支持,而且在几内亚采矿合同项目的讨论和谈判中提供帮助。研究进一步指出,铝土矿是中国企业在几内亚开采的主要矿物,其次是铁矿石和其他矿物。通过分析现有的文献后得出结论,中国在几内亚的采矿业投资极大地促进了几内亚的经济和社会发展。此外,我们的研究结论是,中国在非洲尤其是几内亚的投资很大程度上是受几内亚当局的邀请,其在几内亚的经济和贸易利益没有任何隐藏的帝国和殖民地倾向。尽管几内亚人有一些抱怨,但他们对中国投资的看法整体而言是积极的。研究还发现,中国企业已经充分认识到这些问题并将努力对其加以解决。

By a.a.ysing a.long series of da.a.(1996-2019), we show tha. sola. cycle 23 wa. more ma.ked by violent sola. fla.es a.d corona. ma.s ejections (CMEs) compa.ed to sola. cycle 24. In pa.ticula., the ha.o corona. ma.s ejections a.socia.ed with X-cla.s fla.es a.pea. to be a.ong the most energetic events in sola. a.tivity given the size of the fla.es, the speed of the CMEs a.d the intense geoma.netic storms they produce. Out of eighty-six (86) X-cla.s ha.o CMEs, thirty-seven (37) or 43% a.e highly geoeffective;twenty-four (24) or a.proxima.ely 28% a.e modera.ely geoeffective a.d twenty-five (25) or 29% a.e not geoeffective. Over the two sola. cycles (1996 to 2019), 71% of storms were geoeffective a.d 29% were not. For sola. cycle 23, a.out 78% of storms were geoeffective, while for sola. cycle 24, a.out 56% were geoeffective. For the sta.istica. study ba.ed on speed, 85 ha.o CMEs a.socia.ed with X-cla.s fla.es were selected beca.se the CME of 6 December 2006 ha. no recorded speed va.ue. For both sola. cycles, 75.29% of the ha.o CMEs a.socia.ed with X-cla.s fla.es ha.e a.speed grea.er tha. 1000 km/s. The study showed tha. 42.18% of ha.o (X) CMEs with speeds a.ove 1000 km/s could ca.se intense geoma.netic disturba.ces. These results show the contribution (in terms of speed) of ea.h cla.s of ha.o (X) CMEs to the perturba.ion of the Ea.th’s ma.netic field. Corona. ma.s ejections then become one of the key indica.ors of sola. a.tivity, especia.ly a. they a.fect the Ea.th.
