The Pouni area is made up of basalts belonging to the Boromo belt, lamprophyres and granitoids. These geological formations are similar to geological formations of the same type in other regions of the Palaeoproterozoic domain of the Man/Leo shield. This study, which focused on the petrographic and geochemical characteristics of these geological formations, led to the following main conclusions: The lamprophyres are basic plutonic rocks that cut through other geological formations. The basalt belongs to the northern part of the Borormo belt and is thought to be a relic of overthickened oceanic plateaus. There are two groups of granitoid rocks. The granodiorite has a geochemical signature close to that of Archean TTGs and is metaluminous in character. It has a low potassium content. The minor element and rare earth element spectra indicate that it could be derived from partial melting of basic magmatic rocks. Biotite granites are peraluminous and highly potassic. Minor element contents and rare earth spectra indicate that they could be derived from partial melting of felsic materials. Geotectonic diagrams show that the granitoids identified in the Pouni zone were emplaced in an active tectonic context, similar to that of present-day subduction zones.

目的探索中国7~18岁儿童和青少年的体质量指数(Body Mass Index,BMI)和身高与国民经济发展之间的联系,并预测2025—2030年各年龄段儿童和青少年的身高和BMI,为中国未来制定体质干预政策提供参考。方法1986—2019年7~18岁儿童和青少年的平均BMI和身高数据来自国际心脏代谢危险因素数据库,中国经济发展指标来自中国统计年鉴的历年人均国内生产总值(Gross Domestic Product Per Capita,GDPPC)。分别对男女每一个年龄组检验GDPPC和BMI、身高之间的相关性,使用线性回归和非线性回归来预测随着GDPPC的增长,2025—2030年间每个年龄组的平均身高和BMI。结果男女各年龄组的GDPPC和BMI、身高之间高度相关(P均<0.01)。随着GDPPC的增长,男女各年龄组的BMI稳步增加,但身高增速逐渐下降,各年龄段存在差异。2025—2030年6年的GDPPC增长伴随着7~18岁男、女生的BMI每年增加约0.78%和0.49%,身高每年增加约0.09%和0.18%。结论7~18岁儿童和青少年的身高和BMI在1986—2019年间呈上升趋势,经济发展高度预测身高和BMI增加,要注意各年龄段男女生身高增长速度的差异以及预防儿童和青少年的超重肥胖趋势。

Local Plants Potentially Suitable for Phytoremediation of Soils Polluted by Heavy Metals: The Case of Landfill Sites

引用

Journal of Geoscience and Environment Protection 2024年第7期12卷 72-88页

作者： Kpan Kpan Kouakou Gains Touré Mamadou Ouattara Nouffou Doudjo Kouassi Kouadio Claude Ehouman N’guetta Moïse Ouattara Djibril Tiho seydou UFR Sciences de la Nature Universit Nangui Abrogoua Abidjan Cte dIvoire UFR Agroforesterie Universit Jean Lorougnon Gud Daloa Cte dIvoire

Landfills are contaminated sites that need to be cleaned up to prevent human and environmental exposure to pollutants. This article aims to identify local plants capable of restoring soil polluted by heavy metals. To this end, plant species at the Bonoua landfill were inventoried. X-ray fluorescence spectrometry was used to determine the heavy metal content of soil and plants from the landfill. The bioconcentration factor (BCF) of metals in plants was evaluated. The Bonoua landfill is covered with 62 plant species, comprising 28 botanical families and 50 genera. The BCF varied from 0.08 (titanium) to 2.27 (strontium) for Phyllanthus amarus;from 0.06 (titanium) to 1.83 (copper) for Alternanthera sessilis and from 0.03 (arsenic) to 2.10 (strontium) for Amaranthus spinosus. Phyllanthus amarus, Alternanthera sessilis, and Amaranthus spinosus are strontium-accumulating species (BCF > 1). Similarly, copper BCF values were above 1 for Phyllanthus amarus, and Alternanthera sessilis. These two plant species are therefore copper accumulators. In short, Phyllanthus amarus, Alternanthera sessilis, and Amaranthus spinosus are candidate species for phytoremediation of heavy metal-polluted soils, given their BCF > 1.

The aim of this work is to model the drying kinetics of Safou pulp with or without endocarp using a phenomenological approach. Oven-drying kinetics at 70˚C, 90˚C and 105˚C were monitored using the curves given by the reduced mass as a function of time, which are modeled according to the Avrami/page, Fick and Peleg models using OringinPro 2018 software. The results showed that parameters k and n of the Avrami/Page model vary very little with fruit size and drying temperature (0.0018 ± 0.0002 k n k (Avrami model/page) were virtually identical, while b (Fick model) and n (Avrami model/page) were virtually identical for the same sample. For the Peleg model, the parameter a, varies from 0.0018 ± 0.0002 to 0.03328 ± 0.0079, with a ratio of 18.6 for all experimental conditions studied. However, with 0.977 R2 χ2 tal data. The same applies to parameter b, which ranges from 0.82 ± 0.05 to 1.21 ± 0.02. Thus, drying modeling by these three models can be used to describe and predict the progress of oven-drying of safou pulp.

Diagnosis of childhood tuberculosis (TB) is difficult, especially in resource-limited countries where the number of reported cases of TB-HIV co-infection continues to rise. This co-infection poses a diagnostic and therapeutic problem for caregivers. We report a case of rifampicin-resistant HIV-TB pulmonary coinfection in a 19-month-old infant.

Context: Antiretroviral therapies improve the prognosis of NeuroAIDS contrasting with a high frequency of Minor Neurocognitive Disorders (MND) even in aviremic subjects. Objective: The objective of this study is to present the neurological and cognitive profile of People Living with HIV (PLHIV) initiating antiretroviral treatment in Kinshasa in the era of Dolutegravir (DTG). Methods: This is a multicenter, cross-sectional study with a descriptive aim carried out in 16 HIV Outpatient Treatment Centers (OTC) in Kinshasa from October 4, 2021 to February 15, 2022. The International HIV Dementia Scale (IHDS) correlated with the Activities of Daily Living (IADL) scale facilitated the categorization of NeuroCognitive Disorders (NCD) of PLHIV evaluated after carrying out a summary neurological examination. Results: Of the 96 patients recruited, 56.3% were women with a sex ratio of 0.68. The average age was 40.1 ± 12.1 years. The secondary education level was the majority at 64.6%. Malaria (44.8%) and tuberculosis (32.3%) were more common as opportunistic infections. They were alcoholics in (30.2%). Their history was heart disease (15.6%), high blood pressure (18.8%);drug abuse (10.4%). The IHDS score was light in 55.2% of cases. The correlation between IHDS/IADL watches asymptomatic neurocognitive impairments (ANI) in 77.1%, almost all of subjects are found with normal overall functioning (94.8%) and a disturbed neurological examination in 53.1% of cases with a predominance of motor impairments in 79.1%. Conclusion: In view of these results, early and systematic screening of NCD and associated factors remains necessary in our context. .

“失去黑帐篷草原就会寂寞,失去信仰人心就会寂寞”。在我创作的电影《黑帐篷》中,主角央金是普通牧人家庭的女主人,在传统观念里,家就是男人女人的帐篷。一顶黑帐篷就是生命和爱的全部含义。由于帐篷老旧,央金想编织一顶新的牛毛帐篷让家充满温馨,原本一件天经地义的事,却在时代变革和观念变化以及一系列突如其来的事件中让她梦难成真。通过电影,我们能映射现实,在这个飞速发展的时代,一些传统的,不合时宜的事物必然会逐步淘汰掉,改掉已经习惯的一些生活方式需要一些时间慢慢适应,同样保护和传承一些好的传统文化也需要一些时间。

To develop suitable grouting materials for water conveyance tunnels in cold regions,firstly,this study investigated the performance evolution of ferrite-rich sulfoaluminate-based composite cement(FSAC grouting material)at 20 and 3℃.The results show that low temperature only delays the strength development of FSAC grouting material within the first 3 ***,the effect of four typical early strength synergists on the early properties of FSAC grouting material was evaluated to optimize the early(£1 d)strength at 3℃.The most effective synergist,Ca(HCOO)_(2),which enhances the low-temperature early strength without compromising fluidity was selected based on strength and fluidity *** micro-mechanism was analyzed by XRD,TG,and seM *** results reveal that the most suitable dosage range is 0.3 wt%−0.5 wt%.Proper addition of Ca(HCOO)_(2)changed the crystal morphology of the hydration products,decreased the pore size and formed more compact hydration products by interlocking and ***,excessive addition of Ca(HCOO)_(2)inhibited the hydration reaction,resulting in a simple and loose structure of the hydration *** research results have reference value for controlling surrounding rock deformation and preventing water and mud inrushes during the excavation in cold region tunnels.
