Cross-sectional prevalence and pattern of non-anaemia severe malaria among 2–10 year olds in Sokoto in

Frontiers of Medicine   Pages 969-974 doi: 10.1007/s11684-021-0912-z

Abstract: Malaria is highly prevalent in Nigeria and accounts for approximately 40% of global malaria mortalityfrom communities; thus, malaria-related deaths in the community are left untracked.Severe malaria was diagnosed according to the World Health Organisation criteria.The mean age of children with severe malaria was 3.73 years, and the male–female ratio was 2:1.A relatively high prevalence of non-anaemia severe malaria was found in Wamakko.

Efficient promotion of methane hydrate formation and elimination of foam generation using fluorinated

Quan CAO, Dongyan XU, Huanfei XU, Shengjun LUO, Rongbo GUO

Frontiers in Energy 2020, Volume 14, Issue 3,   Pages 443-451 doi: 10.1007/s11708-020-0683-2

Abstract: Methane hydrate preparation is an effective method to store and transport methane. In promoters to facilitate methane hydrate formation, homogeneous surfactant solutions, sodium dodecyl sulfate (SDS) in particular, are more favorable than heterogeneous particles, thanks to their faster reaction rate, more storage capacity, and higher stability. Foaming, however, could not be avoided during hydrate dissociation with the presence of SDS. This paper investigated the ability of five fluorinated surfactants: potassium perfluorobutane sulfonate (PBS), potassium perfluorohexyl sulfonate (PHS), potassium perfluorooctane sulfonate (POS), ammonium perfluorooctane sulfonate (AOS), and tetraethylammonium perfluorooctyl sulfonate (TOS) to promote methane hydrate formation. It was found that both PBS and PHS achieve a storage capacity of 150 ( , the volume of methane that can be stored by one volume of water) within 30 min, more than that of SDS. Cationic ions and the carbon chain length were then discussed on their effects during the formation. It was concluded that PBS, PHS, and POS produced no foam during hydrate dissociation, making them promising promoters in large-scale application.

Current advances in the elimination of hepatitis B in China by 2030

Shuye Zhang, Fusheng Wang, Zheng Zhang

Frontiers of Medicine 2017, Volume 11, Issue 4,   Pages 490-501 doi: 10.1007/s11684-017-0598-4

Abstract:

With its 78 million chronic carriers, hepatitis B virus (HBV) infection is still one of the leading public health challenges in China. Over the last two decades, China has made great progress on the prevention of HBV transmission through national vaccination programs. Zero transmission from mother to infant has been proposed as the current goal. Available anti-HBV therapy is efficacious in suppressing HBV replication; however, it fails to completely cure patients with chronic hepatitis B and even requires lifelong treatment. To reduce the costs and improve the efficacy, several trials have been recently conducted in China to optimize the current anti-HBV managements. Novel biomarkers were identified to predict treatment outcomes, and new promising treatment strategies were developed. Reports also indicate that coinfections of HBV with other hepatotropic viruses and human immunodeficiency virus are common in China and cause severe liver diseases, which should be recognized early and treated properly. Work is still needed to eliminate hepatitis B in China by 2030.

Study on the Formation and Elimination of Coarse Grains in Cast Steel

Zou Anquan,Deng Peiran

Strategic Study of Chinese Academy of Engineering 2005, Volume 7, Issue 4,   Pages 79-82

Abstract:

The relation between coarse grain and rupture of casts was found through analyzing the formation of coarse grains and tests for eliminating coarse grains on ZG32Cr06 cast steel. The results of tests show that the coarse grains, as a results of too high casting temperature and the premature trunk opening in water explosion blast cleaning , can be eliminated by heat treatment. The measures for preventing coarse grains in casts were proposed.

Extension of pilot tests of cyanide elimination by ozone from blast furnace gas washing water through

Ismael Matino, Valentina Colla, Teresa A. Branca

Frontiers of Chemical Science and Engineering 2018, Volume 12, Issue 4,   Pages 718-730 doi: 10.1007/s11705-018-1771-2

Abstract:

For improving wastewater quality, one of the dare of steelworks is reducing cyanide in wastewater of gas washing treatment of blast furnaces. Costs of existing treatments, stringent environmental regulations and changeable composition of water from gas treatment, have led to study how available treatments can be modified and to examine new ones. Ozonation is one of cyanide treatments, tested within a European project. A process model was set up with Aspen Plus®, to assess operating conditions and wastewater distinctive characteristics and to demonstrate treatment robustness. Process was modeled by theoretical reactors, taking into account all more affecting reactions. A genetic algorithm was exploited to find kinetic parameters of these reactions. After validation, the model was used to analyse scenarios, by considering also real contexts. Pilot tests were extended, process knowledge was enhanced and suggestions were obtained. To promote cyanide removal with ozone, temperature and pH values were 30°C and 10, respectively. With an ozone (mg/h)/water (L/h) ratio of 100 mg/L, batch mode ensure reaching cyanide regulation limit (0.2 mg/L) after maximum 4.5 h, if initial amount was less than 20 mg/L. Higher removal was obtained than in continuous mode due to constraints related to this last run. Higher wastewater contamination needed further time and more ozone.
