The development of the ice-snow tourism needs a scientific and effective method to assess the value of ice-snow tourism resource and its realization degree effectively and reasonability. Based on the analysis of expectation value and realization value of ice-snow tourism resource, this paper designs a three-dimension assessment index system and constructs the method of assessing the value of ic...

From past research it is known that both knowledge-based scene interpretation and knowledge-based configuration can be conceived as logical model construction. In this report we show that also from an applicationoriented point of view, both tasks are very similar and existing configuration technology can be used to implement a generic scene interpretation system with highly useful features, in ...

BACKGROUND The filamentous ascomycete Aspergillus niger is used in many industrial processes for the production of enzymes and organic acids by batch and fed-batch cultivation. An alternative technique is continuous cultivation, which promises improved yield and optimized pipeline efficiency. RESULTS In this work, we have used perfusion (retentostat) cultivation to validate two promoters that...

Mosaic landscapes under shifting cultivation, with their dynamic mix of managed and natural land covers, often fall through the cracks in remote sensing-based land cover and land use classifications, as these are unable to adequately capture such landscapes' dynamic nature and complex spectral and spatial signatures. But information about such landscapes is urgently needed to improve the outcom...

Fixed-bed reactors have gained growing attention for the cultivation of mammalian cells. They allow for a low shear stress cultivation of adherent and non-adherent cells due to the immobilization of cells within macroporous carriers. Their potential has been demonstrated for many cell culture purposes. Some of the recent developments are presented in this review, including improved antibody pro...

The vertical alignment design method of road in scenic spots does not evolve enough along the vehicle’s rapid variation. Values maximum longitudinal slope (MLS) and longest length (LSL) applicable to roads used by environmental-friendly vehicle (EFV) are provided. To compensate for this shortage, a multibody dynamic model uphill traving is built, providing static equilibrium state balancing pro...

Clarke, R.C. 1995. Hemp (Cannabis sativa L.) Cultivation in the Tai'an District of Shandong Province, Peoples Republic of China. Journal of the International Hemp Association 2(2): 57, 60-65. This paper summarizes the history of hemp (Cannabis sativa L.) cultivation and traditional use in the Tai'an District of Shandong Province in the People's Republic of China, and investigates the cultivatio...

Large scale microalgae cultivation actually represents a potential new source of renewable energy in the form of biofuel. Microalgae are individual plant cells which have the ability to photosynthesize and therefore utilize CO2, micronutrients and solar light to multiply and produce carbohydrates, lipids and proteins. Microalgae cultivation has several advantages over land grown crops. The majo...

The microalgae cultivation can be used as alternative sources of food, in agriculture, residual water treatment, and biofuels production. Semicontinuous cultivation is little studied but is more cost-effective than the discontinuous (batch) cultivation. In the semicontinuous cultivation, the microalga is maintained in better concentration of nutrients and the photoinhibition by excessive cell i...

This study found significant relationships between first- and second-order cultivation measures and TV viewing, but found a relationship with video game play for only two variables in a sample of 322 Flemish 3rd and 6th year secondary school children. This suggests that the absence of a relationship with video game play is not the result of the absence of cultivation effects in Flanders. On the...
