背景外周动脉波形分析（PWA）是经肺动脉热稀释法校正后的一种测定心排出量（CO）的方法。PWA系统．Flo—Trac／Vigileo（FTV）法，不需要在使用前定标。我们同时比较了用FTV法和经食管超声心动图（TEE）法测定心排出量的结果。方法选择10例ASAⅠ-Ⅱ，择期行腹腔镜结直肠手术的患者做为研究对象。20G套管针桡动脉置管，与血流动力学监测仪及FTV系统连接，进行PWA分析并测定心排出量（COPWA）。据以往方法进行TEE测定心排出量（COTEE）。记录气管插管后、截石位后5分钟、气腹后5分钟、每30分钟或者每次平均动脉压低于基础值20％的测量值。统计分析用Bland-Altm.n法。结果比较88个测量值，COTEE值为3．23—12Lt／m.n（平均6．21±1．85），COPWA值为2．9—8．5Lt/m.n（平均4．84±1．14），偏差1．17，可信区间-2．02～4．37。所有COTEE和COPWA测定值之间的误差百分率平均为40％，范围27％～50％。结论腹腔镜结肠手术中用TEE和FTV法测定心排出量有明显的临床差异。

Background and Objectives: The indication for treatm.nt in HBsAg-positive patients with low viral load and norm.l transam.nases requires an assessm.nt of fibrosis. In resource-lim.ted settings, free hepatic fibrosis evaluation tests can aid in therapeutic decision-m.king. Our study aim. to dem.nstrate the utility of assessing hepatic fibrosis using non-invasive m.rkers (APRI and FIB-4) in patients with chronic B viral hepatitis without cytolytic activity and low viral replication in our context. Patients and m.thods: This is a retrospective cross-sectional study conducted between January 2018 and Decem.er 2021 at the University Hospital Center of Bouaké. Included were all patients aged ≥18 with norm.l transam.nases (Results: Our study included 241 patients, with a m.an age of 36.19 years (±10.52 years) and a m.le predom.nance of 52%. The m.an FibroScan® value was 6.44 ± 2.3 kPa, and 68 patients (28.22%) had fibrosis >7 kPa. To exclude significant fibrosis (FS Conclusion: A significant proportion of HBV-infected patients with norm.l ALT and low viral load have active liver disease. Both FIB-4 and APRI biological scores are useful in identifying individuals without significant fibrosis with a good negative predictive value (>50%).

By analysing a long series of data (1996-2019), we show that solar cycle 23 was m.re m.rked by violent solar flares and coronal m.ss ejections (Cm.s) com.ared to solar cycle 24. In particular, the halo coronal m.ss ejections associated with X-class flares appear to be am.ng the m.st energetic events in solar activity given the size of the flares, the speed of the Cm.s and the intense geom.gnetic storm. they produce. Out of eighty-six (86) X-class halo Cm.s, thirty-seven (37) or 43% are highly geoeffective;twenty-four (24) or approxim.tely 28% are m.derately geoeffective and twenty-five (25) or 29% are not geoeffective. Over the two solar cycles (1996 to 2019), 71% of storm. were geoeffective and 29% were not. For solar cycle 23, about 78% of storm. were geoeffective, while for solar cycle 24, about 56% were geoeffective. For the statistical study based on speed, 85 halo Cm.s associated with X-class flares were selected because the Cm. of 6 Decem.er 2006 has no recorded speed value. For both solar cycles, 75.29% of the halo Cm.s associated with X-class flares have a speed greater than 1000 km.s. The study showed that 42.18% of halo (X) Cm.s with speeds above 1000 km.s could cause intense geom.gnetic disturbances. These results show the contribution (in term. of speed) of each class of halo (X) Cm.s to the perturbation of the Earth’s m.gnetic field. Coronal m.ss ejections then becom. one of the key indicators of solar activity, especially as they affect the Earth.

This study aim. to im.rove knowledge of the structure of southwest Cam.roon based on the analysis and interpretation of gravity data derived from.the SGG-UGm.2 m.del. A residual anom.ly m.p was first calculated from.the Bouguer anom.ly m.p, which is strongly affected by a regional gradient. The residual anom.ly m.p generated provides inform.tion on the variation in subsurface density, but does not provide sufficient inform.tion, hence the interest in using filtering with the aim.of highlighting the structures affecting the area of south-west Cam.roon. Three interpretation m.thods were used: vertical gradient, horizontal gradient coupled with upward continuation and Euler deconvolution. The application of these treatm.nts enabled us to m.p a large num.er of gravim.tric lineam.nts m.terializing density discontinuities. These lineam.nts are organized along m.in preferential directions: NW-SE, NNE-SSW, ENE-WSW and secondary directions: NNW-SSE, NE-SW, NS and E-W. Euler solutions indicate depths of up to 7337 m. Thanks to the results of this research, significant inform.tion has been acquired, contributing to a deeper understanding of the structural com.osition of the study area. The resulting structural m.p vividly illustrates the m.jor tectonic events that shaped the geological fram.work of the study area. It also serves as a guide for prospecting subsurface resources (water and hydrocarbons). .

This study is a contribution to im.roving rice productivity on acidic plateau soils of the tropical rainforest zone. It is based on taking into account the cationic balances of the soil in order to optim.ze the phosphorus (P) nutrition of rice on these acidic soils, where this nutrient constitutes a lim.ting factor for agricultural production. Three (3) pot trials were conducted in Adiopodoum. in the forested south of Côte d’Ivoire. The interactive effects of calcium.carbonate (0, 25, 50 and 75 kg Ca ha−1) and m.gnesium.sulfate (0, 25, 50 and 75 kg m. ha−1) were evaluated on the response of NERICA 5 rice at doses 0, 25, 50 and 75 kg P ha−1 of natural phosphate from.Togo, applied only once at the start of the experim.nt. Additional fertilizers of nitrogen (N) (100 kg N ha−1) and potassium.(K) (50 kg KCl ha−1) were added to each of the tests in a split-plot device. The test results revealed a paddy production potential of approxim.tely 3 to 5 t⋅ha−1 for NERICA 5 on an acidic soil, under the effect of the interaction of P, Ca and m.. The quadratic response of rice yield to the doses of these fertilizers would be m.re dependent on their balance, itself influenced by Ca nutrition. For the sustainability and m.intenance of rice production in agro-ecology studied, it was recom.ended doses of 38 kg Ca ha−1, 34 kg m. ha−1 in a Ca/m. ratio (1/1) with intakes of 41 kg P ha−1, overall in a ratio 1/1/1 (P/Ca/m.) m.re favorable to the availability of free iron considered a guiding elem.nt of m.neral nutrition. Thus, these prom.sing results should be confirm.d in a real environm.nt for better m.nagem.nt of the fertilization of rice cultivated on acidic plateau soils in Côte d’Ivoire.
