<P><B>Abstract</B></P> <P>Theoretical model of thermoelectric generator (TEG) cooled by direct evaporative cooling technology is developed. In the theoretical model, thermoelectric material properties depending on temperature change and effects of heat loss by radiation, conduction, and Thomson phenomenon are considered. To investigate the effect of evaporative cooling to the efficiency of TEG, the simulation conditions are set as hot-side temperature of 40–120 °C and 1 mm thickness of thin water film covering for cold-side. The ambient temperature is 25 °C and the relative humidity of the air is set from 25% to 75%. Based on the developed theoretical model, the output power of TEG is increased as increasing hot side temperature under fixed relative humidity or as decreasing relative humidity under fixed hot-side temperature. Consequently, the maximum output power of 130.69 W m<SUP>−2</SUP> and an efficiency of 1.63% are obtained with 25% relative humidity and 120 °C for the hot-side temperature condition. The results show that the output power and efficiency are increased 100.53 and 10.53 times higher than without evaporative cooling (natural convection case, output power of 1.30 W m<SUP>−2</SUP> and efficiency of 0.1548%), respectively.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Theoretical model of TEG cooled by direct evaporative cooling technology. </LI> <LI> Thermophysical relations in TEG system and cooling process at theoretical model. </LI> <LI> Analyzing thermal resistance network for quantifying heat flow rates and heat dissipation rates. </LI> <LI> Increasing TEG performance by applying evaporative cooling technology. </LI> <LI> TEG performance evaluation based on hot-side temperature and relative humidity. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

Liang. Huang,Jun. Zheng,Guolv.Tan 보안공학연구지원센터 2015 International Journal of Grid and Distributed Comp Vol.8 No.1
Cloud computing task scheduling is a multi-objective decision on how to perform a variety of tasks simultaneously reasonable sort is essential. Therefore, this article constructs a population of convergence non-dominated sorting method. This method is based on non-dominated sorting method; the use of distributed estimation method is improved by four steps to complete the task order scheduling. The experimental results show that this method has good convergence and distribution.

Purpose Microtubule-associated protein 1 light chain 3B (LC3B) serves as a key component of autophagy, which is associated with the progression of carcinoma. Yet, it is still unclear whether LC3B is also an independent risk factor for intrahepatic cholangiocarcinoma (ICC). We aim to explore the predictive value of LC3B on prognosis of ICC, and to establish a novel and available nomogram to predict relapse-free survival (RFS) and overall survival (OS) for these patients after curative-intent hepatectomy. Materials and Methods From August 2004 to March 2017, 105 ICC patients were eligibly enrolled in the Third Affiliated Hospital of Sun Yat-sen University. Preoperative clinical information of enrolled patients was collected. Expression LC3B in the ICC specimen was detected by immunohistochemistry. Results The 5-year RFS and OS in this cohort were 15.7% and 29.6%, respectively. On multivariate Cox regression analysis, independent risk factors for 5-year OS were cancer antigen 125, microvascular invasion, LC3B expression and lymph node metastasis. Except for the above 4 factors, neutrophil/lymphocyte ratio and tumor differentiation were independent factors for 5-year RFS. The area under the curve of nomograms for OS and RFS were 0.820 and 0.747, respectively. Conclusion The nomograms based on LC3B can be considered as effective models to predict postoperative survival for ICC patients.

Liang-Yao Chen,Yun-Fei Wu,Qing-Yuan Cai,Yu-Xiang Zheng,Rong-Jun Zhang 한국물리학회 2008 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.53 No.4
The broadband optical monitoring (BOM) method for the thin-film coating proces has become more popular due to its having a higher efficiency than other methods and the ability to precisely control the film coating proces at any thicknes. A high-resolution spectrometer working in the broadband spectral range has to be used for the BOM method to monitor the growth proces of a narow bandpas thin-film filter. In this paper, we show the application of a high-resolution spectrometer in BOM for the narow bandpas thin-film filter-coating proces and away to eliminate effectively the interference eror of the substrate. We also describe an experimental setup that can be used to grow a narow bandpas filter in a real BOM proces.

Aims: The prognosis of hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT) is very poor. According to the BCLC treatment recommendations, sorafenib or other palliative treatment (PT) is recommended as the first-line therapy when it happens. In real world, however, a significant number of selected patients with HCC and PVTT suffered from surgical resection (SR). Methods: PubMed, Embase, Medline and Cochrane library were searched for studies comparing SR with PT (including TACE, sorafenib, etc.) for HCC with PVTT, which were published before September 2017. Results: 4,810 patients from 7 studies were enrolled in this meta-analysis, which divided into the SR group (n = 2,344) and the PT group (n = 2476). When compared with the PT group, the pooled hazard ratio (HR) for the 1, 3 and 5-year OS rates of the SR group were 0.56 (95% CI 0.52-0.60, P=0.03), 0.56 (95% CI 0.53-0.59, P<0.001) and 0.55 (95% CI 0.54-0.57, P<0.001). For subgroup analysis, when compared with the mere TACE group, the pooled HR for the 1, 3 and 5-year OS rates of the SR group were 0.54 (95% CI 0.43-0.67, P=0.81), 0.75 (95% CI 0.65-0.87, P=0.25) and 0.76 (95% CI 0.67-0.88, P=0.25). Conclusions: This meta-analysis demonstrated SR had better OS than TACE or other palliative therapy for HCC with PVTT. SR may be suitable as the first-line treatment for selected patients with resectable HCC and removable PVTT.

Biofilms are of vital significance in bioconversion and biotechnological processes. In this work, sugarcane molasses was used to enhance biofilms for the improvement of the production of fumigaclavine C (FC), a conidiation-associated ergot alkaloid with strong anti-inflammatory activities. Biofilm formation was more greatly induced by the addition of molasses than the addition of other reported biofilm inducers. With the optimal molasses concentration (400 g/l), the biofilm biomass was 6-fold higher than that with sucrose, and FC and conidia production was increased by 5.8- and 3.1-fold, respectively. Moreover, the global secondary metabolism regulatory gene laeA, FC biosynthetic gene fgaOx3, and asexual central regulatory genes brlA and wetA were upregulated in molasses-based biofilms, suggesting the upregulation of both asexual development and FC biosynthesis. This study provides novel insight into the stimulatory effects of molasses on biofilm formation and supports the widespread application of molasses as an inexpensive raw material and effective inducer for biofilm production.

A total of 49 phenolic compounds were identified from the aged red wines made from Cabernet Gernischt (Vitis vinifera L. cv.) grapes, a Chinese characteristic variety, including 13 anthocyanins, 4 pryanocyanins, 4 flavan-3-ol monomers, 6 flavan-3-ol polymers, 7 flavonols, 6 hydroxybenzoic acids, 5 hydroxycinnamic acids, 3 stilbenes, and 1 polymeric pigment. Evolution of these compounds was investigated in wines aged 1 to 13 months. Variance analysis showed that the levels of most phenolics existed significant difference in between wines aged 3 and 9 months. Cluster analysis indicated that 2 groups could be distinguished, one corresponding to wines aged 1 to 3 months and the other to wines aged 4 to 13 months. It was thus suggested that there were 2 key-stages for the development of fine wine quality, at the aged 3 and 9 months, respectively. This work would provide some helpful information for quality control in wine production.

Blackleg is a serious disease in Brassica plants, causing moderate to severe yield losses in rapeseed worldwide. Although China has not suffered from this disease yet (more aggressive Leptosphaeria maculans is not present yet), it is crucial to take provisions in breeding for dis- ease resistance to have excellent blackleg-resistant cul- tivars already in the fields or in the breeding pipeline. The most efficient strategy for controlling this disease is breeding plants with identified resistance genes. We selected 135 rapeseed accessions in Sichuan, including 30 parental materials and 105 hybrids, and we deter- mined their glucosinolate and erucic acid content and confirmed 17 double-low materials. A recently devel- oped single-nucleotide polymorphism (SNP) marker, SNP_208, was used to genotype allelic Rlm1/rlm1 on chromosome A07, and 87 AvrLm1-resistant materials. Combined with the above-mentioned seed quality data, we identified 11 AvrLm1-resistant double-low rapeseed accessions, including nine parental materials and two hybrids. This study lays the foundation of specific R gene-oriented breeding, in the case that the aggressive Leptosphaeria maculans invades and establishes in Chi- na in the future and a robust and less labor consuming method to identify resistance in canola germplasm.
