Heat Transfer in a Liquid-Solid Circulating Fluidized Bed Reactor with Low Surface Tension Media

引用

Chinese Journal of Chemical Engineering 2013年第8期21卷 844-849页

作者： H.R.Jin H.lim D.H.lim Y.Kang ki-Won Jun Chemical Engineering Chungnam National University Daejeon Korea Korea Chemical Technology Division Korea Research Institute of Chemical Technology

Heat transfer characteristics between the immersed heater and the bed content were studied in the riser of a liquid-solid circulating fluidized bed, whose diameter and height were 0.102 m (ID) and 2.5 m, respectively. Effects of liquid velocity, particle size, surface tension of liquid phase and solid circulation rate on the overall heat transfer coefficient were examined. The heat transfer coefficient increased with increasing particle size or solid circulation rate due to the higher potential of particles to contact with the heater surface and promote turbulence near the heater surface. The value of heat transfer coefficient increased gradually with increase in the surface tension of liquid phase, due to the slight increase of solid holdup. The heat transfer coefficient increased with the liquid velocity even in the higher range, due to the solid circulation prevented the decrease in solid holdup, in contrast to that in the conventional liquid-solid fluidized beds. The values of heat transfer coefficient were well correlated in terms of dimensionless groups as well as operating variables.

World Journal of Gastroenterology 2005年第14期11卷 2072-2079页

AIM: Expression of heat shock proteins (HSPs) is frequently up-regulated in hepatocellular carcinoma (HCC), which evolves from dysplastic nodule (DN) and early HCC to advanced HCC. However, little is known about the differential expression of HSPs in multistep hepatocarcinogenesis. It was the purpose of this study to monitor the expression of HSPs in multistep hepatocarcinogenesis and to evaluate their prognostic significance in hepatitis B virus (HBV)related ***: Thirty-eight HCC and 19 DN samples were obtained from 52 hepatitis B surface antigen-positive Korean patients. Immunohistochemical and dot immunoblot analyses of HSP27, HSP60, HSP70, HSP90, glucoseregulated protein (GRP)78, and GRP94 were performed and their expression at different stages of HCC development was statistically ***: Expression of HSP27, HSP70, HSP90, GRP78, and GRP94 increased along with the stepwise progression of hepatocarcinogenesis. Strong correlation was found only in GRP78 (Spearman's r= 0.802). There was a positive correlation between the expressions of GRP78, GRP94, HSP90, or HSP70 and prognostic factors of HCC. Specifically, the expression of GRP78, GRP94, or HSP90 was associated significantly with vascular invasion and intrahepatic ***: The expressions of HSPs are commonly up-regulated in HBV-related HCCs and GRP78 might play an important role in the stepwise progression of HBVrelated hepatocarcinogenesis. GRP78, GRP94, and HSP90 may be important prognostic markers of HBV-related HCC, strongly suggesting vascular invasion and intrahepatic metastasis.

Genipin Cross-Linked Polyvinyl Alcohol-Gelatin Hydrogel for Bone Regeneration

引用

Journal of Biomedical Science and Engineering 2016年第9期9卷 419-429页

作者： Thi-Hiep Nguyen Reiza Ventura Young-ki Min Byong-taek Lee Department of Regenerative Medicine College of Medicine Soonchunhyang University Asan South Korea Department of Physiology College of Medicine Soonchunhyang University Asan South Korea Institute of Tissue Regeneration College of Medicine Soonchunhyang University Asan South Korea

Polyvinyl alcohol gelatin hydrogels were fabricated using genipin as a crosslinking agent for bone regeneration application. Optimized formulation of PVA-GE hydrogel was fabricated using genipin as crosslinking agent. Characterizations such as FTIR, morphology, porosity, pore size, degradation and swelling rate were investigated. Bone regeneration potential of optimized genipin cross-linked polyvinyl alcohol-gelatin (PVA20) hydrogels was assessed by implanting in rabbit’s femur defect for 1, 5 and 15 weeks period. Results showed interconnected porosity as observed in scanning electron microscopy and successful crosslinking as confirmed by FTIR analysis. Increased porosity (92% ± 2.46%) and pore size distribution (100 - 200 μm) were also observed as well as decrease in swelling rate (426% ± 10.50%). Bone formation was evident in micro-CT after 5 and 15 days of in vivo implantation period. Micro-CT analysis showed 32.67% increased bone formation of PVA-GE hydrogel defect compared with negative control after 15 weeks of in-vivo implantation. Histological analyses showed no inflammatory reaction post implantation and increase in cell matrix formation after 5 and 15 weeks. The combined physical and chemical method of crosslinking promises improved mechanical properties of PVA-GE hydrogel making it a potential scaffold for bone tissue engineering applications.

This study was undertaken to determine the impact on ejaculatory function of tamsulosin （0.2 mg） given once daily （OD） for 12 weeks and to identify risk factors for ejaculatory dysfunction in patients undergoing this treatment. Males with an International Prostatic Symptom Score （IPSS） ≥ 8 were enrolled in this study. All participants completed questionnaires, including the IPSS and the Male Sexual Health Questionnaire （MSHQ）, and serum prostate-specific antigen, transrectal ultrasound and uroflowmetry with post-void residual were measured. After initiating 0.2 mg OD tamsulosin, patients were re-evaluated on the fourth and twelfth weeks of medication. The chi-squared test, the independent t-test and one-way ANOVA were used to compare means. Binary logistic regression analysis was used to calculate the odds ratio for all risk factors. A total of 177 men constituted the study cohort. No significant difference was observed between baseline and follow-up for the erectile function, ejaculatory function, satisfaction, sexual activity and desire domains （EFD, EjFD, SDA and ADD） or for erectile or ejaculatory bother mean scores. After 12 weeks, the overall incidence of ejaculatory dysfunction （EjD） was 13.4%. Incidences of the seven different types of EjD （decreased frequency, delay, dryness, decreased strength/force, decreased volume, decreased pleasure and pain at ejaculation） were 2.4%, 3.1%, 3.9%, 3.9%, 6.3%, 7.1% and 3.1%, respectively. Baseline EjFD scores were higher for I PSS responders than for non-responders （26.09 vs. 24.06, P=0.03）. An EjFD score reduction was more frequent in IPSS responders. The incidence of EjD was small, but not negligible and was more frequent in patients with less lower urinary tract symptoms, a smaller prostate, higher baseline MSHQ totals and higher EjFD scores.

AIM:To determine the accuracy of computed tomography (CT) and magnetic resonance (MR) for presurgical characterization of paraaortic lymph nodes in patients with pancreatico-biliary carcinoma. METHODS:Two radiologists independently evaluated CT and MR imaging of 31 patients who had undergone lymphadenectomy (9 metastatic and 22 non-metastatic paraaortic nodes). Receiver operating characteristic (ROC) curve analysis was performed using a five point scale to compare CT with MRI. To re-define the morphologic features of metastatic nodes, we evaluated CT scans from 70 patients with 23 metastatic paraaortic nodes and 47 non-metastatic ones. The short axis diameter, ratio of the short to long axis, shape, and presence of necrosis were compared between metastatic and non-metastatic nodes by independent samples t-test and Fisher's exact test. P 5.3 mm), irregular margin, and presence of central necrosis are the suggestive morphologic features of metastatic paraaortic nodes.

通过氮掺杂TiO_(2)(N-TiO_(2))浸渍蜂窝过滤器构建了一系列原型光催化空气净化器(AP(N_(x)-C_(y)))系统,并用于在UV-LED光(1 W)照射条件下光催化分解0.5-5 ppm甲醛(CH_(2)O)蒸汽.在上述催化过滤器系统中,Nx和Cy分别代表N/Ti摩尔比(0-20)和N-TiO_(2)浓度(2-20 mg mL^(-1)).光催化分解实验结果表明,AP(N_(10)-C_(10))的性能最好,其催化CH2O转化为CO_(2)的转化率最高,循环反应10次后CO_(2)产率仍达到89.2%,在干燥空气中的清洁空气输送速率为9.45 L min^(-1).N10-C10的电荷载流子寿命(τa:1.70 ns)优于其他样品(如纯TiO_(2)的电荷载流子寿命为1.37 ns),这表明N缺陷(No)有助于降低带隙(3.10 eV)和产生氧空位OVs-Ti^(3+),这与密度泛函理论(DFT)模拟结果一致.采用原位漫反射红外傅里叶变换、电子顺磁共振和DFT分析等多种方法研究了CH_(2)O的光催化氧化途径.结果表明,氧化过程涉及多个能量有利的中间步骤(例如CH2O以CH_(2)O_(2)的形式在TiO_(2)-OV{110}表面的桥连O/OH基团上发生放热共价吸附,随后通过催化脱氢/氧化反应直接生成CO_(2):CH_(2)O_(2)/HCOO^(-)+•OH→H_(2)O+CO_(2)).这些步骤与具有N杂质的{101}表面上化学活性Ti原子的态密度计算结果一致.预计No缺陷和OVs的存在将通过降低活化能垒来影响反应能量和中间产物,从而在加湿条件下实现有效的矿化.综上,本文为设计和构建先进的光催化系统,并用于环境空气中醛类挥发性有机物(VOCs)的有效矿化提供了新思路.
