To achieve the current study, geoelectrical surveys along six (06) profiles of 4 km long in a 100 m × 200 m grid defined according to the triangulation principle in the Tindikala-Boutou (Eastern-Cameroon) area along the Kadey River have been made through electrical sounding and profiling following Schlumberger array. the instrument is the resistive meter Syscal Junior 48 (IRIS Instrument). the data have been processed and modelled with Res2Dinv and Winsev softwares, and then interpolated with Surfer software. Investigation method used is the Direct Current (DC) method. Interpretations and analyses of results from the investigation method highlight weak zones or conductive discontinuities. the latter has been identified as shear zones within granitic structures of the Precambrian basement, according to the geologic and tectonic background of the area. the structural trend of these shear zones is E-W approximately. the mineralization characterized by conductive zones proves the presence of clay minerals disseminated in weathered quartz vein, which cross the shear zones. the intense activities of gold washers encountered in the studied area are able to attest the presence of clay minerals concentrations.

DKP Oscillator in a Noncommutative Space

Communications in theoretical Physics 2008年第9期50卷 587-592页

作者： m.Falek m.merad Département de Physique Centre Universitaire de Oum-El-Bouaghi04000 Oum-El-BouaghiAlgeria Laboratoire de Physique théorique Université de Louis PasteurStrasbourgFrance

We present the DKP oscillator model of spins 0 and 1, in a noncommutative space. In the case of spin 0, the equation is reduced to Klein Gordon oscillator type, the wave functions are then deduced and compared with the DKP spinless particle subjected to the interaction of a constant magnetic field. For the case of spin 1, the problem is equivalent with the behavior of the DKP equation of spin 1 in a commutative space describing the movement of a vectorial boson subjected to the action of a constant magnetic field with additional correction which depends on the noncommutativity parameter.

对于目的在于微震活动性分析的地方台网来说,利用初动方向确定震源机制的传统方法可能受到限制,因为很少能观测到清晰的初动。许多利用振幅的替代方法已被提出。辐射远场,体波低频频谱振幅依赖于地震矩和震源方向,利用它会从振幅观测资料中得到断层面解。对观测频谱振幅要进行关于自由表面效应、衰减、仪器响应和几何扩散的校正。在整个参数空间内对走向、倾角和倾伏角进行搜索,以满足极性观测并给出观测与预测振幅间“充分小的”最小二乘拟合的震源取向作为该地震的可能震源机制。对冰岛的一个地方台网范围内的震源,用反射率法来产生合成地震图。利用振幅反演算法求合成地震图。在8个台站上反演无干扰振幅,对被检验的所有机制来说,在所有的震源角中,所得到的解与正确机制的偏差小于10°。加上干扰和调整合成数据以模拟不同震级事件的结果表明,对于震级低达m_L=0.5的地方事件来说,这种方法给出的断层面解在所有3个震源角中与正确值相差在±15°之内。

Comparison of different lymph node staging systems in prognosis of gastric cancer:a bi-institutional study from Hungary

引用

Chinese Journal of Cancer Research 2017年第4期29卷 323-332页

作者： Dezso Toth Adrienn Bfra Zsolt Vargal miklos Torok Peter peter Akosy Department of General Surgery Kenezy Gyula Teaching Hospital Debrecen 4031 Hungary Department of General Thoracic and Vascular Surgery Kaposi M6r Teaching Hospital Kaposv~r 7400 Hungary Department of Pathology Ken6zy Gyula Teaching Hospital Debrecen 4031 Hungary Department of Oncology Kan6zy Gyula Teaching Hospital Debrecen 4031 Hungary

Objective： the Union for International Cancer Control （UICC） Node （N） classification is the most common used staging method for the prognosis of gastric cancer. It demands adequate, at least 16 lymph nodes （LNs） to be dissected; therefore different staging systems were invented. methods： Between march 2005 and march 2010, 164 patients were evaluated at the Department of General Surgery in the Ken^zy Gyula Hospital and at the Department of General, thoracic and Vascular Surgery in the Kaposi m6r Hospital. the 6th, 7th and 8th UICC N-staging systems, the number of examined LNs, the number of harvested negative LNs, the metastatic lymph node ratio （mLR） and the log odds of positive LNs （LODDS） were determined to measure their 5-year survival rates and to compare them to each other. Results： the overall 5year survival rate for all patients was 55.5% with a median overall survival time of 102 months. the tumor stage, gender, UICC N-stages, mLR and the LODDS were significant prognostic factors for the 5-year survival with univariate analysis. the 6th UICC N-stage did not follow the adequate risk in comparing N2 vs. NO and N3 vs. NO with multivariate investigation. Comparison of performances of the residual N classifications proved that the LODDS system was first in the prediction of prognosis during the evaluation of all patients and in cases with less than 16 harvested LNs. the mLR gave the best prognostic prediction when adequate （more than or equal to 16） lymphadenectomy was performed. Conclusions： We suggest the application of LODDS system routinely in western patients and the usage of mLR classification in cases with extended lymphadenectomy.

西德斯图加特大学空气动力学与气体动力学研究所(IAG)的跨音速翼型风洞的实验m数范围为0.4～0.95,采用喉道面积控制法,m数最大误差不超过±0.0035。该风洞有性能较好的三分力天平。模型在风洞中不对称放置,以减小上壁面对翼型上表面的压力分布的干扰,即可增大翼型弦长(L)与风洞半高(S)之比,从而可增大实验雷诺数。在该风洞中对于风洞半高及翼型弦长之比(S/L)对升力系数及流动二元性的影响进行了实验研究,结果表明,当mm数及迎角的变化情况,由实验结果可以看出,流动二元性不仅随m数及迎角有较大的变化,而且受S/L的影响。

Context: Despite the new recommendations “Test and Treat”, the virological and molecular parameters remain important information for Antiretroviral Treatment and adequate for monitoring of patients infected with HIV/AIDS. Objective: the Objective of this study is to present the virological and molecular profile of People Living with HIV starting Antiretroviral therapy in Kinshasa in the era of the Dolutegravir. methods: this was a transversal study to determine virological and molecular profile of People Living with HIV (PLHIV) starting an ARV Treatment. the patient’s inclusion period was from October 04, 2021 to February 15, 2022. A sample of 5 ml of blood was taken in a tube with EDTA anticoagulant for molecular Biology analyzes (Viral Load and Sequencing) in all HIV patients, after reading and signing informed consent. the population was made up of adult patients over the age of 18, infected with HIV and starting ART. Results: 119 patients (56.3% of women) were included in this study, thus a sex-ratio of 1.29. the average age of patients included was 39.87 ± 12.36 years. the most represented age group is that of 36 to 45 with 37 patients (31.9%) followed by that from 26 to 35 years with 24 patients (20.7%). Out of 119 patients, 21 patients had an undetectable Viral Load (VL). the median value of VL was 4.16 log10 RNA copies/ml. 114 samples were successfully amplified. Subtype A was dominant with 23 cases (20.2%);followed by the subtype C and CRF02_AG each with 14.0%, and D (10.5 %). K65R (1.8%), T69P/N (4.4%), K70R (7.9%) and m184V (7.0%) mutations were listed as existing mutations for Nucleotide Transcriptase Inhibitors. Conclusion: 38 patients (31.93%) started the TARV with a positive virological prognosis. the subtype A remains dominant in Kinshasa with 23 cases (20.2%);followed by the subtype C and CRF02_AG each with 14.0%. For Inhibitors of Transcriptase Reverse Nucleotide;K65R, T69P/N, K70E/R and m184V mutations were found in patients’ naive of ARV Treatmen
