Abstract A two-dimensional version of the Pennsylvania State University mesoscale model has been applied to Winter Monsoon Experiment data in order to simulate the diurnally occurring convection observed over the South China Sea. The domain includes a representation of part of Borneo as well as the sea so that the model can simulate the initiation of convection. Also included in the model are parameterizations of mesoscale ice phase and moisture processes and longwave and shortwave radiation with a diurnal cycle. This allows use of the model to test the relative importance of various heating mechanisms to the stratiform cloud deck, which typically occupies several hundred kilometers of the domain. Frank and Cohen's cumulus parameterization scheme is employed to represent vital unresolved vertical transports in the convective area. The major conclusions are: Ice phase processes are important in determining the level of maximum large-scale heating and vertical motion because there is a strong anvil componen...

Numerical study of convection observed during the Winter Monsoon Experiment using a mesoscale two-dimensional model [presentation]

Fluorescent carbon nanoparticles or carbon quantum dots (CQDs) are a new class of carbon nanomaterials that have emerged recently and have garnered much interest as potential competitors to conventional semiconductor quantum dots. In addition to their comparable optical properties, CQDs have the desired advantages of low toxicity, environmental friendliness low cost and simple synthetic routes. Moreover, surface passivation and functionalization of CQDs allow for the control of their physicochemical properties. Since their discovery, CQDs have found many applications in the fields of chemical sensing, biosensing, bioimaging, nanomedicine, photocatalysis and electrocatalysis. This article reviews the progress in the research and development of CQDs with an emphasis on their synthesis, functionalization and technical applications along with some discussion on challenges and perspectives in this exciting and promising field.

Carbon quantum dots and their applications

Flexural creep behavior of a Y-α-β sialon composite was studied in air at temperatures of 1250–1350°C and stresses of 110–290 MPa. The composite in which YAG was designed as intergranular phase has an original α/β ratio of 65/35. The stress exponents in Norton equation were determined to be 1.31±0.12, 1.49±0.15 and 1.62±0.10 at 1250, 1300 and 1350°C, respectively, and creep activation energy was 677±25 kJ mol −1 . Combining the microstructure observations, grain boundary diffusion accommodated by grain boundary sliding was identified as the rate-controlling creep mechanism for the composite. The creep rate exponent p in Monkman–Grant relation was found to be 1.6, and the nucleation and growth of cavities in triple grain pockets was responsible for the creep rupture.

In this paper, we study the steelmaking-continuous casting (SCC) production scheduling problem. Considering the constraints of the practical technological requirements and the objective of minimizing the total waiting time of jobs, we formulate a mathematical programming model. Due to the complexity of the model, we solve it by a decomposition strategy, i.e. jobs are allocated and sequenced on machines first, and the time table of all jobs is then established. We propose a tabu search algorithm to deal with the allocation and sequencing decisions and use a linear programming model to establish the time table of jobs. For tabu search algorithm, we design three different neighborhood structures, including the insertion neighborhood, the restricted neighborhood whose size is changeable, and a kick strategy based on swap move. We test the proposed algorithm on a set of real problems, and the computational results demonstrate the effectiveness of the proposed algorithm.

The moon jellyfish (Aurelia sp.1) is thought to be a nuisance for the sea cucumber aquaculture, which commonly occur in the sea cucumber (Apostichopus japonicus) culture ponds of the Yellow Sea, China. To develop an appropriate method to control Aurelia sp.1 blooms, the toxic effects of tea saponin on Aurelia sp.1 ephyrae and polyps were tested in laboratory experiments. Our results revealed that tea saponin caused significant morphological changes, behavioral abnormality and mortality in Aurelia sp.1 ephyrae and polyps in 24 h and 48 h exposure experiments. The 24 h and 48 h median lethal concentrations (LC50) values of tea saponin for Aurelia sp.1 ephyrae were 1.9 and 1.1 mg L-1 respectively, while the LC50 value for Aurelia sp.1 polyps was 0.4 mg L-1 after 24h and 48 h of exposure to tea saponin. Comparison with literature results of tea saponin on A. japonicus indicates that the resistance of A. japonicus to tea saponin is 12-18 times greater than that of Aurelia sp.1 ephyrae. Therefore, the appropriate tea saponin dosage for the control of Aurelia sp.1 should be paid enough attention in order to minimize possible damage for sea cucumber. We suggest that the recommended level of tea saponin to eradicate Aurelia sp.1 ephyrae and polyps in sea cucumber culture ponds be lower than 1.35 mg L-1.
