The palmately veined leaves of sweetgum (Liquidambar styraciflua L.) were found more sensitive to the major vein severing than that of other species Major veins severing resulted in serious water stresses, as indicated by the persistent reddening and/or advanced reddening of local leaf, lower leaf stomatal conductance, and higher leaf temperature, etc. Severed leaf can be clearly divided into non-severed area, transitional area, and stressed area, which the three areas have different colours and temperature. The major vein barrier can also be seen clearly. The persistent reddening and advanced reddening seem consistent with the phenomenon of red crown top of some sweetgum trees and may have similar mechanism.展开更多

Intensified micromixing and uniform nucleation environment are created by the high-gravity equipment (rotating packed bed) in carrying out the anti-solvent precipitation process to produce nanoparticles. The average particle size decreases from 55 μm of the raw danazol to 190 nm of the nanoparticles. The Brunauer-Emmett-Teller (BET) surface area sharply increases from 0.66 m^2·g^-1 to 15.08 m^2·g^-l. Accordingly, the dissolution rate is greatly improved. The molecular state, chemical composition, and crystal form of the danazol nanoparticles remains unchanged after processing according to Fourier transform infrared (FTIR) and X-ray diffraction (XRD), The high recovery ratio and continuous production capacity are highly appreciated in industry. Therefore, the HGAP method might offer a general and facile platform for mass production of hydrophobic pharmaceutical danazol particles in nanometer range.展开更多

Particular em-phasis lies on soil degradation and other adverse ecological and environmental effects of the prevalent andirrational land-use systems of mono-and valley-agriculture in the region. Moreover, taking into account thesimultaneous existence of enormous potentials and serious constraints and the high diversity and complexityof the biophysical and socio-economic environments, a set of strategies and counterineasures are also prc-posed for appropriate management of environmental resources, in terms of maintaining harmony betweenutilization and conservation of the natural environment, including 1) adjustment of the agricultural structureand optimization of ecological patterns of stereo-agriculture; 2) improvement and integrated exploitation ofthe low-yield lands and wastelands; 3) rehabilitation and conservation of soil and water resources; and 4)establishment of production bases of tropical and subtropical cash crops and fruits.展开更多

All results confirmed the previous observations of thermal anomalies in the seismic region prior to this earthquake.Among the multi-parameter anomalies, the underground water temperature anomaly appeared first and lasted for the longest time; OLR anomaly,an infrared parameter which indicates the radiation characteristics of the land surface medium,was the first to be detected; LST anomalies appeared later than OLR. NCEP temperature indicates the average atmosphere temperature with a certain vertical thickness; therefore,it was the last detected anomaly. The anomalies of OLR and LST lasted for a similar time length and were all located in the south or southwest of the epicenter.展开更多

Samples of leaves, stem and roots were collected randomly from the selected specie (Avicennia marina). The study site is receiving continuous amount of heavy metals from effluent and discharge of different sources. The concentrations of heavy metals was in decreasing order Fe 〉 Cd 〉 Pb 〉 Hg in all three parts (leaves, stem and roots) of the Avicennia marina. The average concentration of Fe was 6.45 μg/g, Cd 0.97μg/g, and Pb 0.71μg/g, in mangrove plant Avicennia marina. The situation reflects the needs for continuous monitoring of the heavy metals in the mangrove plant forest.展开更多

Its challenge derives mainly from the failure of the existing socio-economic system to cope with the aging process. The intervention of public policy is therefore inevitable. This paper argues that in order to comprehensively deal with the aging problem, it is not sufficient to merely readjust population policies, policy measures focusing on the aged or policies for one or another sector. Instead, we need to reconstruct the current public policy system from the perspective of social integration and a long-term development strategy. During the reconstruction process, efforts should be made not only to coordinate the population system with other social systems, but also to coordinate short-term goals with medium and longterm strategies. Accordingly, an authoritative permanent government coordinating agency should be established and, taking into account China's national conditions, should redefine the social role of senior citizens, solve practical problems related to support for the aged and support the sustainable development of an aging society.展开更多
