The δ18O and δ2H stable isotope techniques for studying properties of groundwater and surface help us to understand more clearly about the distribution and movement of groundwater in the South of Hanoi area. There were 68 water samples from the studying area and analyzed by a Liquid Water Isotope Analyzer (LWIA-24D). The stable isotope values of the groundwater from Pleistocene aquifers were range from -3.21‰ to -9.55‰ δ18O and -35.32‰ to -67.44‰ δ2H;rainwater from -8.18‰ to -4.13‰ δ18O and -61.19‰ to -17.93‰ δ2H;Red river water from -7.51‰ to -5.29‰ δ18O and -51.60‰ to -38.99‰ δ2H. Based on stable isotope characteristics, the results show that there was a relationship between surface water and groundwater in the South of Hanoi city. It is that groundwater recharges for river water in the dry season with 74%, and in the rainfall season groundwater is recharged from river with 87%.

This study, which assesses the quality of soils under cocoa trees in the Marahoué region of Côte d’Ivoire, is being carried out against a backdrop of declining crop yields due to a number of factors, including the loss of soil fertility. The aim was to identify homogeneous groups of soils in terms of fertility and propose sustainable management methods for each group. The study was carried out on twenty-four cocoa orchards belonging to the SCOOP KAPATCHIVA cooperative, spread over eight sectors. A morphological characterisation of the soils was carried out in the field, followed by physico-chemical laboratory analyses of soil samples taken in the field. Soil fertility was analyzed on the basis of these two groups of data. The results showed that soil depths were generally high, except in some high altitude areas, where soils were often enriched in ferromagnesian elements and compacted. The texture of the soils varied between loamy and sandy-loamy, influencing cocoa production. Indeed, the soils of the plots with high production were looser and without ferromagnesian concretions, while those of the plots with low production were more gravelly and compact. Biological activity in the upper soil layer (0 - 30 cm) was notable with an abundance of termites and earthworms. The organic matter and nitrogen content varies considerably between sectors, directly impacting soil fertility. The soils were slightly acidic and showed significant differences in the levels of exchangeable magnesium and potassium, and not at all for phosphorus which appeared at very low doses. Chemical analysis also revealed that nutrient balance was a key factor in orchard productivity, with varying ratios of calcium, magnesium and potassium. Knowledge of these results made it possible to make recommendations for soil management with a view to improving cocoa yields in the study area.

Objective:To characterize viral co-infections among representative hospitalized measles cases during the 2014 Hanoi ***:Throat swabs were collected from 54 pediatric patients with confirmed measles,and molecular diagnostics performed for 10 additional viral respiratory pathogens(Influenza A/H1N1pdm09;A/H3N2 and influenza B;Parainfluenza 1,2,3;Respiratory Synctial Virus,RSV;human Metapneumovirus,hM PV;Adenovirus and Picornavirus).Results:Twenty-one cases(38.9%) showed evidence of infection with other respiratory viruses:15 samples contained measles plus one additional virus,and 6 samples contained measles plus 2 additional *** was detected as a predominant cause of co-infections(13 cases;24.1%),followed by RSV(6 cases;11.1%),A/H1N1pdm09(3 cases;5.6%),PIV3(3 cases;3.7%),Rhinovirus(3 cases;3.7%) and hM PV(1 case;1.96%).Conclusions:Viral co-infections identified from pediatric measles cases may have contributed to increased disease severity and high rate of fatal *** treatment of measles cases may require control of multiple viral respiratory pathogens.

Emergency cerclage with advanced cervical dilatation and bulging of fetal membranes is still challenging to obstetricians.?Objective:?To identify the live birth rate after physical examination indicated rescue cerclage. Methods:?A retrospective cohort study of 36 pregnant women, who underwent rescue cerclage at Hung Vuong hospital from January 2015 to January 2019. Selection criteria: cervical dilation 10 to 40 mm, at 20 to 30 gestational weeks. Exclusion criteria: multiple pregnancy, birth defects, pregnancy termination due to maternal or fetal indications. Results: Delivery of live infant rate was 72.22%;mean pregnancy prolongation was 42.8 ±?34.15 days. Early live birth rate was 77.78%. The percentage of delivery after 34 and 37 weeks was 44.45% and 27.78%, respectively. Live birth weight was 400 to 3600?g, with mean being 1878.06 ±?1049.04?g. No procedure-related complication was observed. Conclusions:?Rescue cerclage may be an effective and safe method in prolonging pregnancy and improving neonatal outcome in women with cervical dilation 10 to 40 mm. It should be considered as a viable option for women with a dilated cervix in 20 to 30 gestational weeks. Future controlled studies are needed.

本文旨在更好地解读国家政策与移民流动性之间的相互关系。基于门槛分析方法,我们建立了关于边界、流动性和移民的基础理论,并重点探讨了具有移民倾向的个体心理过程。人们往往根据以下3个地理门槛作出移民抉择:一是关注迁移、离开熟悉的地方、跨越国界的想法;二是关注目的地区位及其边界和"接壤"(Bordering);三是关注迁移路径或途径。本文的案例主要来自欧盟和东南亚国家,分别包括荷兰和德国之间的跨界现象,2008年经济危机后欧盟的人口流动,2015-2016年期间欧盟和土耳其间的难民流动,菲律宾劳工移民,以及印度尼西亚—马来西亚迁徙通道等。最后,本文讨论了流动性和边界政策及治理。
