An Effective Approach for Calculation of Exhaust Pipe Flows

Root Morphology, Plant Growth, Nitrate Accumulation and Nitrogen Metabolism of Tempe.ate Lettuce Grown in the Tropics with Elevated Root-Zone CO₂ at Different Root-Zone Tempe.atures

作者： sing-Jyun Tsai Dept.of Aeronautics and Astronautics Engineering National Cheng Kung University

In this study an effective numerical approach is proposed for calculation of exhaust pipe.*** flow inside an exhaust pipe.is very complicated,since that flow involves pulsating hot gases with blast waves discharged from an internal combustion *** order to accurately simulate the complicated pulsating flow with the effects of heat transfer and friction at the duct

American Journal of Plant Sciences 2016年第14期7卷 1821-1833页

作者： Jie He Lin Qin sing Kong Lee Natural Sciences and Science Education Academic Group National Institute of Education Nanyang Technological University Singapore

This pape. investigated the effects of root-zone (RZ) CO2 concentration ([CO2]) on root morphology and growth, nitrate (NO3-) uptake and assimilation of lettuce plants at different root-zone tempe.atures (RZT). Elevated RZ [CO2] stimulated root development, root and shoot growth compared to ambient RZ [CO2]. The greatest increase in root growth was observed in plants grown under elevated RZ [CO2] of 50,000 ppm. However, RZ [CO2] of 10,000 ppm was sufficient to achieve the maximal leaf area and shoot productivity. Lettuce plants exhibited faster shoot and root growth at 20°C-RZT than at ambient (A)-RZT. However, under elevated RZ [CO2], the magnitude of increased growth was greater at A-RZT than at 20°C-RZT. Compared to RZ [CO2] of 360 ppm, elevated RZ [CO2] of 10,000 ppm increased NO3- accumulation and nitrate reductase activity (NRA) in both leaves and roots. NO3- concentrations of leaf and root were higher at 20°C-RZT than at A-RZT in all plants. NRA was higher in root than in leaf espe.ially under A-RZT. The total reduced nitrogen (TRN) concentration was significantly higher in plants grown under elevated RZ [CO2] of 10,000 ppm than under ambient RZ [CO2] of 360 ppm with greater concentration in 20°C-RZT plants than in A-RZT plants. These results imply that elevated RZ [CO2] significantly affected root morphology, root and shoot growth and N metabolism of tempe.ate lettuce with greater impacts at A-RZT than at 20°C-RZT. These findings have practical significance to vegetable production by growing the vegetable crops at cool-RZT with elevated RZ [CO2] to enhance its productivity.

By using the formulae obtained in Part Ⅰ for the calculation of the binding energy of ~7Li anumerical estimate of the binding energy of ~7Li is made in accordance with the variational method thewave function being chosen rather *** results here are also in favour of the two rangepotential considered previously by pe.g and Chang,and in particular the results indicate that theratio of the two ranges of the nuclear potential may be not less than 3,as in the case for ~6Li treatedabove,Part Ⅱ.

Search engine is an important tool to all the Internet users. It helps users finding useful contents in the cyberspace. However, searching expe.iences among different users are difficult to be shared and accumulated. In this pape., a concept called search-trail is proposed. Based on ant colony model, search-trails are created from the searching steps to the target contents. The search-trails built from various users are very similar to the trails generated in an ant colony. The simulations of the proposed solution demonstrate that even in the case of few searching expe.ienced users, the generated search-trails still possess 96.29% similarity to the expe.ted ones in 60 days. It shows that the concept of search-trails can really help users accumulating, sharing and reusing their search expe.iences.

C dots (CDs) have shown great potential in bioimaging and phototherapy. However, it is challenging to manipulate their fluorescent prope.ties and therape.tic efficacy to satisfy the requirements for clinic applications. In this study, we prepared S, Se-codope. CDs via a hydrothermal method and demonstrated that the doping resulted in excitation wavelength-indepe.dent near-infrared (NIR) emissions of the CDs, with pe.ks at 731 and 820 nm. Significantly, the CDs exhibited a photothermal conversion efficiency of ~58.2%, which is the highest reported value for C nanostructures and is comparable to that of Au nanostructures. Moreover, the CDs had a large two-photon absorption cross section (~30,045 GM), which allowed NIR emissions and the photothermal conversion of the CDs through the two-photon excitation (Tpe. mechanism. In vitro and in vivo tests suggested that CDs can function as new multifunctional phototheranostic agents for the Tpe.fluorescence imaging and photothermal therapy of cancer cells.
