| 1 | Effect of phosphorus fluctuation caused by river water dilution in eutrophic lake on competition between blue-green alga Microcystis aeruginosa and diatom Cyclotella sp.显示文摘Tega-numa (Lake Tega) is one of the eutrophic lakes in Japan. For the improvement of water quality in Lake Tega, the North-chiba Water Conveyance Channel was constructed in 2000, which transfer water from Tone River into the lake. After 2000, the dominant species of diatoms, mainly Cyclotella sp., have been replacing blue-green algae, mainly Microcystis aeruginosa in Lake Tega. This transition of dominant species would be due to the dilution, but the detail mechanism has not been understood yet. This study examined the relationship between phosphorus fluctuation caused by river water dilution to Lake Tega and dominance of algal species, M. aeruginosa or Cyclotella sp. based on the single-species and the mixed-species culture experiments. The single-species culture experiment showed that the half-saturation constant and uptake rate of phosphorus were one order lower and seven times higher for M. aeruginosa than those for Cyclotella sp. These findings implied that M. aeruginosa would possess a potential for the growth and survival over Cyclotella sp. in the phosphorus limited condition. The superiority of M. aeruginosa was reflected in the outcome of the mixed-species culture experiment, i.e., dominance of M. aeruginosa, even phosphorus concentration was lowered to 0.01 mg-P/L. Therefore, it could be concluded that the decrease in phosphorus concentration due to the river water dilution to Lake Tega would be interpreted as a minor factor for the transition of dominant species from M. aeruginosa to Cyclotella sp. | Yoshimasa Amano Yusuke Sakai Takumi Sekiya Kimitaka Takeya Kazuo Taki Motoi Machida | 2010 | Journal of Environmental Sciences2010，22，11： | 16 |
| 2 | Modeling and experimental validation of heat transfer and energy consumption in an innovative greenhouse structure显示文摘The commercial greenhouse is one of the most effective cultivation methods with a yield per cultivated area up to 10 times more than free land cultivation but the use of fossil fuels in this production field is very high.The objectives of this paper are to modeling and experimental evaluation of heat and mass transfer functions in an innovative solar greenhouse with thermal screen.For this propose,a semi-solar greenhouse was designed and constructed at the North-West of Iran in Azerbaijan Province(38100N and 46180E with elevation of 1364 m above the sea level).The inside environment factors include inside air temperature below screen(Ta),inside air temperature above screen(Tas),crop temperature(Tc),inside soil temperature(Ts),cover temperature(Tri)and thermal screen temperature(Tsc)were collected as the experimental data samples.The dynamic heat and mass transfer model used to estimate the temperature in six different points of the semi-solar greenhouse with initial values and consider the crop evapotranspiration.The results showed that dynamic model can predict the inside temperatures in four different points(Ta,Tc,Tri,Ts)with MAPE,RMSE and EF about 5-7%,1-2℃ and 80-91%for greenhouse without thermal screen and about 3-7%,0.6-1.8C and 89-96%for six different points of greenhouse with thermal screen(Ta,Tc,Tri,Ts,Tas,Tsc),respectively.The results of using thermal screen at night(12 h)in autumn showed that this method can decrease the use of fossil fuels up to 58%and so decrease the final cost and air pollution.This movable insulation caused about 15℃ difference between outside and inside air temperature and also made about 6℃ difference between Ta and Tas.The experimental results showed that inside thermal screen can decrease the crop temperature fluctuation at night. | Morteza Taki Yahya Ajabshirchi Seyed Faramarz Ranjbar Abbas Rohani Mansour Matloobi | 2016 | Information Processing in Agriculture2016，3，3： | 10 |
| 3 | Applied machine learning in greenhouse simulation;new application and analysis显示文摘Prediction the inside environment variables in greenhouses is very important because they play a vital role in greenhouse cultivation and energy lost especially in cold and hot regions.The greenhouse environment is an uncertain nonlinear system which classical modeling methods have some problems to solve it.So the main goal of this study is to select the best method between Artificial Neural Network(ANN)and Support Vector Machine(SVM)to estimate three different variables include inside air,soil and plant temperatures(Ta,Ts,Tp)and also energy exchange in a polyethylene greenhouse in Shahreza city,Isfahan province,Iran.The environmental factors which influencing all the inside temperatures such as outside air temperature,wind speed and outside solar radiation were collected as data samples.In this research,13 different training algorithms were used for ANN models(MLPRBF).Based on K-fold cross validation and Randomized Complete Block(RCB)methodology,the best model was selected.The results showed that the type of training algorithm and kernel function are very important factors in ANN(RBF and MLP)and SVM models performance,respectively.Comparing RBF,MLP and SVM models showed that the performance of RBF to predict Ta,Tp and Ts variables is better according to small values of RMSE and MAPE and large value of R2 indices.The range of RMSE and MAPE factors for RBF model to predict Ta,Tp and Ts were between 0.07 and 0.12C and 0.28-0.50%,respectively.Generalizability and stability of the RBF model with 5-fold cross validation analysis showed that this method can use with small size of data groups.The performance of best model(RBF)to estimate the energy lost and exchange in the greenhouse with heat transfer models showed that this method can estimate the real data in greenhouse and then predict the energy lost and exchange with high accuracy. | Morteza Taki Saman Abdanan Mehdizadeh Abbas Rohani Majid Rahnama Mostafa Rahmati-Joneidabad | 2018 | Information Processing in Agriculture2018，5，2： | 8 |
| 4 | Histological diagnosis of gastric submucosal tumors: A pilot study of endoscopic ultrasonography-guided fine-needle aspiration biopsy vs mucosal cutting biopsy显示文摘AIM: To compare the usefulness of endoscopic ultrasonography-guided fine-needle aspiration biopsy(EUS-FNAB) without cytology and mucosal cutting biopsy(MCB) in the histological diagnosis of gastric submucosal tumor(SMT).METHODS: We prospectively compared the diagnostic yield, feasibility, and safety of EUS-FNAB and those of MCB based on endoscopic submucosal dissection. The cases of 20 consecutive patients with gastric SMT ≥1 cm in diameter. who underwent both EUS-FNAB and MCB were investigated.RESULTS: The histological diagnoses were gastrointestinal stromal tumors(n = 7), leiomyoma(n =6), schwannoma(n = 2), aberrant pancreas(n = 2), and one case each of glomus tumor, metastatic hepatocellular carcinoma, and no-diagnosis. The tumors' mean size was 23.6 mm. Histological diagnosis was made in 65.0% of the EUS-FNABs and 60.0% of the MCBs, a nonsignificant difference. There were no significant differences in the diagnostic yield concerning the tumor location or tumor size between the two methods. However, diagnostic specimens were significantly more frequently obtained in lesions with intraluminal growth than in those with extraluminal growth by the MCB method(P = 0.01). All four SMTs with extraluminal growth were diagnosed only by EUSFNAB(P = 0.03). No complications were found in either method.CONCLUSION: MCB may be chosen as an alternative diagnostic modality in tumors showing the intraluminal growth pattern regardless of tumor size, whereas EUSFNAB should be performed for SMTs with extraluminal growth. | Hisatomo Ikehara Zhaoliang Li Jiro Watari Masato Taki Tomohiro Ogawa Takahisa Yamasaki Takashi Kondo Fumihiko Toyoshima Tomoaki Kono Katsuyuki Tozawa Yoshio Ohda Toshihiko Tomita Tadayuki Oshima Hirokazu Fukui Ikuo Matsuda Seiichi Hirota Hiroto Miwa | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，14： | 7 |
| 5 | 一种人工天青石矿的浮选及夹带行为的统计分析(英文)显示文摘研究浮选参数对泡沫浮选脉石回收率的影响,测试了pH=10时起泡剂类型和捕收剂用量对浮选性能的影响。采用方差分析了测试结果。在用油酸钠作捕收剂的情况下,亲水性矿物的浮选主要是由于Ca+2离子对石英的活化产生的疏水性而导致的夹带作用所引起的;夹带和矿泥包裹层对浮选也有一定的影响。在浮选产物中脉石的夹带程度随着矿石颗粒粒度的减小而增加。实验结果表明,通过增大捕收剂用量、缩短浮选时间,可以减小水流夹带作用,提高浮选的选择性。 | Taki GüLER ünal AKDEMR | 2012 | Transactions of Nonferrous Metals Society of China2012，22，1： | 5 |
| 6 | Diagnosis of small intramucosal signet ring cell carcinoma of the stomach by non-magnifying narrow-band imaging: A pilot study显示文摘AIM: To examine the efficacy of non-magnifying narrow-band imaging(NM-NBI) imaging for small signet ring cell carcinoma(SRC).METHODS: We retrospectively analyzed 14 consecutive small intramucosal SRCs that had been treated with endoscopic submucosal dissection(ESD) and 14 randomly selected whitish gastric ulcer scars(control). The strength and shape of the SRCs and whitish scars by NM-NBI and white-light imaging(WLI) were assessed with Image J(NIH, Bethesda).RESULTS: NM-NBI findings of SRC showed a clearly isolated whitish area amid the brown color of the surrounding normal mucosa. The NBI index, which indicates the potency of NBI for visualizing SRC, was significantly higher than the WLI index(P = 0.001), indicating SRC was more clearly identified by NM-NBI. Although the NBI index was not significantly different between SRCs and controls, the circle(C)-index, as an index of circularity of tumor shape, was significantly higher in SRCs(P = 0.001). According to the receiveroperating characteristic analysis, the resulting cut-off value of the circularity index(C-index) for SRC was 0.60(85.7% sensitivity, 85.7% specificity). Thus a lesion with a C-index ≥ 0.6 was significantly more likely to be an SRC than a gastric ulcer scar(OR = 36.0; 95%CI: 4.33-299.09; P = 0.0009).CONCLUSION: Small isolated whitish round area by NM-NBI endoscopy is a useful finding of SRCs which is the indication for ESD. | Jiro Watari Toshihiko Tomita Hisatomo Ikehara Masato Taki Tomohiro Ogawa Takahisa Yamasaki Takashi Kondo Fumihiko Toyoshima Jun Sakurai Tomoaki Kono Katsuyuki Tozawa Yoshio Ohda Tadayuki Oshima Hirokazu Fukui Seiichi Hirota Hiroto Miwa | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，12： | 4 |
| 7 | Solar thermal simulation and applications in greenhouse显示文摘In this study,a comprehensive review focusing on key strategies of energy saving technologies based on simulation of heat and mass transfer and also artificial intelligent for climate controlling is presented.Following the brief and concise assessment of existing greenhouse systems in terms of their role in total energy consumption;effective shape and structure,energy-efficient and new technologies are analyzed in detail for potential utilization in greenhouses for notable reductions in energy consumption and also go toward the sustainability.The technologies considered within the scope of this research are mainly renewable and sustainable based solutions such as photovoltaic(PV)modules,solar thermal(T)collectors,hybrid PV/T collectors and systems,phase change material(PCM)and underground based heat storage techniques,energy-efficient heat pumps,alternative facade materials for better thermal insulation and power generation.The findings from the research clearly reveal that up to 70%energy saving can be achieved through appropriate retrofit of conventional greenhouses.Using of solar greenhouses in Europe is more popular than others.In some countries in Asia such as Iran,it is very restrict to invest on renewable projects because of cheap fossil fuels.So it is recommended beside of investments by private investors,the Iranian government should also invest in the extension of solar energy in greenhouse by setting up a specialized agency or contracting firms.Those should target the modeling and design the best shape of solar greenhouse for all agricultural areas to receive the maximum solar radiation and decrease the need of fossil fuels. | Morteza Taki Abbas Rohani Mostafa Rahmati-Joneidabad | 2018 | Information Processing in Agriculture2018，5，1： | 4 |
| 8 | Intraspinal transplantation of motoneuron-like cell combined with delivery of polymer-based glial cell line-derived neurotrophic factor for repair of spinal cord contusion injury显示文摘To evaluate the effects of glial cell line-derived neurotrophic factor transplantation combined with adipose-derived stem cells-transdifferentiated motoneuron delivery on spinal cord contusion injury,we developed rat models of spinal cord contusion injury,7 days later,injected adipose-derived stem cells-transdifferentiated motoneurons into the epicenter,rostral and caudal regions of the impact site and simultaneously transplanted glial cell line-derived neurotrophic factor-gelfoam complex into the myelin sheath.Motoneuron-like cell transplantation combined with glial cell line-derived neurotrophic factor delivery reduced cavity formations and increased cell density in the transplantation site.The combined therapy exhibited superior promoting effects on recovery of motor function to transplantation of glial cell line-derived neurotrophic factor,adipose-derived stem cells or motoneurons alone.These findings suggest that motoneuron-like cell transplantation combined with glial cell line-derived neurotrophic factor delivery holds a great promise for repair of spinal cord injury. | Alireza Abdanipour Taki Tiraihi Taher Taheri | 2014 | Neural Regeneration Research2014，9，10： | 3 |
