The research analyzed the dynamic reIationship of rural financial deveIopment, efficiency and farmer＇s incomes based on VAR modeI, and the resuIts indicated that the ex-pansion of rural finance wouId stimuIate farmer＇s incomes in a Iong term, and the growth of rural financial efficiency significantIy improves farmer＇s incomes in a short term, instead of a Iong term. Hence, it is necessary to introduce more credit funds and social funds to rural areas, deepen rural financial system reform and acceIerate use rate of Ioan capital and enhance guidance for farmers and township enterprises in use of Ioan capitals.展开更多

Meanwhile, based on the target data of overal land use plan, the level of land comprehensive carrying capacity was predicted at the end of the plan period （2020） .The results showed that land comprehensive carrying capacity had a significant growth in Lin ’an from 2005 to 2012, and the development trend was basical y sustainable. The sub-systems also had been greatly improved, in which the constant improvement of ec-ological environment carrying capacity made the largest contribution to the constant raising of land comprehensive carrying capacity. The degree of coordination between the systems was poor, in which eco-environment carrying capacity had the maxi-mum growth, far more than the social and economic carrying capacities. According to the land comprehensive carrying capacity in 2020, utilization of land resources in Lin＆#39;an city can achieve sustainable development in general. Final y, proposals of im-proving comprehensive carrying capacity were put forward in terms of the enhance-ment of eco-environment protection, accelerating economic development and policy guidance.展开更多

First, a set of Kepler periodic sequences is generated to permutate image data, which is characteristic of the plain-image and the Keplers third law. Then, a random Hadamard matrix is constructed by combining the standard Hadamard matrix with the hyper-Chen chaotic system, which is used to further scramble the image coefficients when the image is transformed through random Hadamard transform. In the end, the permuted image presents interweaving diffusion based on two special matrices, which are constructed by Kepler periodic sequence and chaos system. The experimental results and performance analysis show that the proposed encrypted scheme is highly sensitive to the plain-image and external keys, and has a high security and speed, which are very suitable for secure real-time communication of image data.展开更多

Our calculations show that when the impurities are added to the edge of the molecule, the anti-resonant peaks will appear in the transmission diagram in the vicinity of the Fermi energy level. So it increases the thermoelectric figure of merit of the system in comparison with the one that the impurity is located in the center of molecule. Additionally, the seebeck coefficient signs are not the same among the B, N, and N ＆ B doped devices, indicating that the types of the carriers can be changed with different types of doping.展开更多

A descriptive, cross-sectional evaluation completed over two years, utilised a postal questionnaire to investigate patient’s satisfaction with aspects of service. Qualitative responses to open questions on satisfaction with emotional support (n = 103) and contributions to well-being (n = 90) were analysed using a framework approach which identified eight themes. Professional knowledge and expertise, service accessibility, caring attributes, enabling patients to cope with anxiety, depression and meeting changing needs contributed positively to both patient well-being and emotional support. Family support was influential on emotional support alone, whilst mediating medical liaison exerted an impact on well-being by enhancing feelings of security. In conclusion, the specialist nursing service contributed positively to well-being and emotional support of patients and thereby to selective aspects of continuity of care.展开更多
