Double-Input DC-DC Converter for Applications with Wide-Input-Voltage-Ranges
Hu, Renjun,Zeng, Jun,Liu, Junfeng,Yang, Jinming The Korean Institute of Power Electronics 2018 JOURNAL OF POWER ELECTRONICS Vol.18 No.6
The output power of most facilities for renewable energy generation is unstable due to external environmental conditions. In distributed power systems with two or more sources, a stable output can be achieved with the complementary power supply among the different input sources. In this paper, a double-input DC-DC converter with a wide-input-voltage-range is proposed for renewable energy generation. This converter has the following advantages: the circuit is simple, and the input voltage range is wide and the fault tolerance is excellent. The operation modes and the steady-state analysis are examined. Finally, experimental results are illustrated to verify the correctness of the analysis and the feasibility of the proposed converter.

Uranium removal from uranium plant wastewater using zero-valent iron in an ultrasonicfield was investigated. Batch experiments designed by the response surface methodology(RSM) were conducted to study the effects of pH, ultrasonic reaction time, and dosage ofzero-valent iron on uranium removal efficiency. From the experimental data obtained inthis work, it was found that the ultrasonic method employing zero-valent iron powdereffectively removes uranium from uranium plant wastewater with a uranium concentrationof 2,772.23 mg/L. The pH ranges widely from 3 to 7 in the ultrasonic field, and theprediction model obtained by the RSM has good agreement with the experimental results.
IL10 and TNF variants and risk of non-Hodgkin lymphoma among three Asian populations
Hosgood III, H. Dean,Au, Wing-Yan,Kim, Hee Nam,Liu, Jie,Hu, Wei,Tse, Jovic,Song, Bao,Wong, Kit-fai,Lee, Je-Jung,Chanock, Stephen J.,Siu, L. P.,Purdue, Mark P.,Shin, Min-ho,Yu, Jinming,Liang, Raymond,K Springer-Verlag 2013 International journal of hematology Vol.97 No.6
<P>Genetic variation in immune-related genes, such as IL10 and TNF, have been associated with the development of non-Hodgkin lymphoma (NHL) in Caucasian populations. To test the hypothesis that IL10 and TNF polymorphisms may be associated with NHL risk in Asian populations, we genotyped 20 single nucleotide polymorphisms (SNPs) within the IL10 and TNF/LTA loci in three independent case-control studies (2635 cases and 4234 controls). IL10 rs1800871, rs1800872, and rs1800896 were genotyped in all three studies, while 5 of the remaining SNPs were genotyped in two studies, and 12 in a single study. IL10 rs1800896 was associated with B cell lymphoma [per-allele odds ratio (OR)?=?1.25, 95?% confidence interval (CI)?1.08-1.45; p trend?=?0.003], specifically diffuse large B cell lymphoma (DLBCL) (per-allele OR?=?1.29, 95?% CI?1.08-1.53; p trend?=?0.004), as well as T cell lymphoma (per-allele OR?=?1.44, 95?% CI?1.13-1.82; p trend?=?0.003). TNF rs1800629, which was genotyped in only two of our studies, was also associated with B cell lymphoma (per-allele OR?=?0.77, 95?% CI?0.64-0.91; p trend?=?0.003), specifically DLBCL (per-allele OR?=?0.69, 95?% CI?0.55-0.86; p trend?=?0.001). Our findings suggest that genetic variation in IL10 and TNF may also play a role in lymphomagenesis in Asian populations.</P>
