This paper discusses the factors affecting livestock farmers' adoption of the biogas technology, using the Tobit model based on the pig-raising household survey in Hunan province. The results show that, biogas technology adoption behavior is negatively correlated with variables as householder's gender ...
Shanghai Marine economy after years of development, has been involved in many industry, Marine industries to local economic contribution in ascension. This article mainly analysis the industrial competitive strength, industrial competition environment, industrial competition potential of the three aspects, ...
Based on the calculation and analysis of the aged population and the death rate at different ages for the counties and districts in ShangHai Coastal Zone, this paper presents the trend of rural aging population by the method of improved Leslie equation. The conclusion is: the rural population in coastal ...
Based on remote sensing images and the land use vector map of 1980, 1995 and 2000, through superposing and analyzing, the tempo-spatial process of land-use change from 1980 to 1995 and 1995 to 2000 in Jiaozhou Bay is achieved. With analysis on land-use change patterns and their driving forces, the main ...
Acid volatile sulfides (AVS) and simultaneously extracted metals (SEM) of 11 surface sediment samples collected from the Sea Area of the Yellow River Estuary were determined. The AVS, SEM, SEM-AVS and their distributions were analyzed. The result shows: AVS in the surface sediment of the sea area was ...
Worldwide demand for renewable energy is increasing rapidly because of the climate problem, and also because oil resources are limited. Wind energy appears as a clean and good solution to cope with a great part of this energy demand. As space is becoming scarce for the installation of onshore wind turbines, ...
Antibiotics into the environment through after adsorption, transport and degradation of a series of bio-transformation process gradually removed from the environment. The degradation of antibiotics in the environment are mainly hydrolysis, photolysis and biological degradation, etc.. Biodegradation ...
According to the characteristics of the ecological agriculture and the ecological supply chain, the concept and architecture of regional ecological agricultural supply chain are proposed. According to the present situation and problems of the agriculture development of the poyang lake ecological economic ...
Aerobic static litter composting, by using sawdust as main litter materials and adding with pig manure and pig slurry every day, under different ventilation rates of 0,0.01 m3/min and 0.02m3/min was studied in pilot scale for obtaining the best ventilation rate. The indexes such as temperature, C/N, ...
Low carbon economy developmental models are the basic measures to cope with the global climate change. The text from the angle of carbon cycling, analyzed the effect of agriculture, water conservancy, land production and other human activity on carbon cycling in irrigation district, presented the conception ...
A method determining the clenbuterol and salbutamol in pork was developed. The method was based on SPE(C18), separated by ZOBAX SB C18,and using a mobile phase of 0.01mol/L Sodium dihydrogen phosphate - Acetonitrile in gradient clution, detected with wavelength 210nm. The linear relations in the scope ...
Eel bones as raw material, the use of enzyme and acid extraction of pepsin-soluble collagen (PSC), and its physical and chemical properties were determined. The results showed that the thermal denaturation temperature of the pepsin-soluble collagen (PSC) is 25 °C; shrinkage temperature is 57.94 °C, ...
IT convergence based applications rely on an amalgamation of different technologies to provide various functionalities. In designing such applications, the primary focus is on integrating the appropriate technologies to deliver the required functionalities and services. While the functional requirements ...
This paper presents the behavior design and multimodal locomotion control of a biomimetic amphibious robot based on a bio-inspired CPG (central pattern generator). A set of four key parameters are introduced serving as external stimuli to shape the CPG rhythmic activities where necessary speed and orientation ...
This paper studies the impact of agricultural extension on agricultural production technical efficiency, using data from agricultural census of China. A stochastic frontier production model is applied to evaluate the effects of agricultural extension on technical efficiency. The empirical results suggest ...
1.Fluctuations in the quality of the habitat in which an animal lives can have major consequences for its behaviour and physiological state. In poor-quality habitat with low food availability, metabolically intensive foraging activity is likely to result in increased generation of reactive oxygen species, ...
Fisheries management is continually frustrated by the lack, or poor quality, of critical data on fishing operations. The only way to accurately monitor at-sea activities and to harness the vast data-gathering and observation potential of fishers, is to introduce electronic data recording and reporting ...
Since the 90s, the topics about fisheries sustainable development had been carried out by international organizations including FAO and many researchers, especially in the fields of sustainable utilization of fisheries resources (SUFR). However, in this fields, one of the most important and urgent topics ...
We present results from a widely tunable (296 cm-1) Quantum Cascade laser based sensor used in sensing water vapor and target gases found in wood smoke in the rural fishing village of Elmina, Ghana.
