拖网渔船艉门架设计方法及研究     

焦尔  刘平  郑建丽  谌志新 《渔业现代化》2014,(5)

艉门架是拖网渔船的关键强力构件,其结构形式和强度直接影响捕捞作业的效率和安全。在分析艉门架工作原理和受力的基础上,运用两种结构力学方法,即两端刚性固定梁和平面刚架解析法,对设计计算结果进行分析和比较,并对推荐方法所得的艉门架结构进行受力分析验证。数值计算结果表明,在极限工况下结构强度能够达到使用要求,验证了艉门架结构设计的合理性。本文对经典结构力学公式进行分析、整理和归纳后,给出的弯矩影响系数表达式对提高船舶艉门架或类似结构的设计效率和优化构件尺寸具有实用价值。  相似文献

Early systemic inflammatory response in mice after a single oral gavage with live Escherichia coli is evidenced by increased TNF-alpha and nitric oxide production     

Nemec A  Jerin A  Zdovc I  Budefeld T  Verstraete FJ  Eržen D  Sentjurc M  Petelin M  Hitti T  Pavlica Z 《Research in veterinary science》2012,92(3):401-407

Twenty-four female BALB/c mice were orally inoculated with 10(8) CFU Escherichia coli ATCC 25922 and euthanized 2.5, 7, 13 and 25 h post-inoculation. The levels of organ nitric oxide (NO) and plasma endotoxin, TNF-alpha and nitrite/nitrate (NO(x)) were compared to those found in sham-inoculated mice, to evaluate systemic host-response to a low-level oral exposure to Gram-negative bacteria. Organ bacterial culture and immunohistochemistry for iNOS were performed on lungs, liver, kidneys and brain from all mice. Organ NO and plasma TNF-alpha levels were higher in E. coli-inoculated animals, but no differences were detected in plasma endotoxin levels, NO(x) or iNOS immunostaining for any of the animal groups. Single oral gavage with live E. coli stimulates an early systemic immune response in clinically healthy mice as evidenced by increased plasma TNF-alpha and organ NO levels, but bacteremia and endotoxemia are not related to this inflammatory response.  相似文献

Evaluation of Aqueous Biphasic Electrophoresis System Based on Halide-Free Ionic Liquids for Direct Recovery of Keratinase     

Phei Er Kee  Hip Seng Yim  Akihiko Kondo  John Chi-Wei Lan  Hui Suan Ng 《Marine drugs》2021,19(8)

Aqueous biphasic electrophoresis system (ABES) incorporates electric fields into the biphasic system to separate the target biomolecules from crude feedstock. Ionic liquid (IL) is regarded as an excellent candidate as the phase-forming components for ABES because of the great electrical conductivity, which can promote the electromigration of biomolecules in ABES, and thereby enhances the separation efficiency of the target biomolecules from crude feedstock. The application of electric fields to the conventional biphasic system expedites the phase settling time of the biphasic system, which eases the subsequent scaling-up steps and reduces the overall processing time of the recovery process. Alkyl sulphate-based IL is a green and economical halide-free surfactant when compared to the other halide-containing IL. The feasibility of halide-free IL-based ABES to recover Kytococcus sedentarius TWHK01 keratinase was studied. Optimum partition coefficient (K_e = 7.53 ± 0.35) and yield (Y_T = 80.36% ± 0.71) were recorded with IL-ABES comprised of 15.0% (w/w) [EMIM][ESO₄], 20.0% (w/w) sodium carbonate and 15% (w/w) crude feedstock. Selectivity (S) of 5.75 ± 0.27 was obtained with the IL-ABES operated at operation time of 5 min with 10 V voltage supplied. Halide-free IL is proven to be a potential phase-forming component of IL-ABES for large-scale recovery of keratinase.  相似文献

Iron bioavailability of different sources in juvenile grouper Epinephelus coioides          下载免费PDF全文

Qin‐Cheng Huang  Er‐Long Wang  Amoah Kwaku  Xiao‐Hui Dong  Bei‐Ping Tan  Shu‐Yan Chi  Qi‐Hui Yang  Shuang Zhang  Hong‐Yu Liu  Yuan‐Zhi Yang 《Aquaculture Research》2018,49(8):2799-2807

A 70‐day experiment was implemented to study the iron (Fe) bioavailability of three Fe sources in Epinephelus coioides (initial weight, 12.19 ± 0.14 g). Treatments consisted of 0, 50, 90, 130, 170 and 210 mg supplemental Fe/kg from iron sulphate (FeSO₄), ferric citrate (Fe‐citrate) and hydroxy methionine analogue iron (Fe‐MHA). The results showed that the growth performance was not affected by Fe level regardless of Fe sources. Hepatic catalase activity (CAT), the haematocrit value (Hct), haemoglobin (Hb), mean corpuscular volume (MCV) and Fe content in whole body or liver firstly increased significantly and then plateaued as Fe level increased regardless of the Fe source, except significant decreasing of Hct in 210 mg Fe/kg group from FeSO₄. Manganese (Mn) content decreased significantly and then kept stable in the whole body and liver whatever the source was. The slope‐ratio method using FeSO₄ as the reference and Hb content, CAT activity, body and hepatic Fe concentration as the response parameter showed the average relative bioavailability of Fe‐citrate and Fe‐MHA was 103.25 ± 4.35 (n = 4) and 134.5 ± 15.67 (n = 4), respectively, with the maximum value of Fe‐MHA in any case. In conclusion, Fe‐MHA was the most effective to meet preferable haematological index, CAT activity and mineral deposition, with little difference between Fe‐citrate and FeSO₄, athough Fe levels with different sources failed to influence the growth in grouper.  相似文献
