Since the implementation of the agriculture supporting policies in 2004, the productive forces in rural areas have been improved greatly. It is reflected on the following aspects: great enhancement of rural labors' cultural quality; the quantity of agricultural machines has been increased; the level of production management and decision has been increased greatly. The paper analyzes the promotion role played by the development of productive forces to rural residents' consumption conception. The development of productive forces has laid a solid foundation for changing rural residents' consumption concept; changed rural residents' consumption structure and improved the socialized degree of rural residents' consumption. Countermeasures on cultivating new consumption fields in rural areas are put forward including leading rural residents to foster the modern consumption conception; intensifying the governmental support and leading rural residents to set up healthy consumption concept.展开更多

This paper also discusses which of the two limiting factors, i.e., soil water or fertility, is the primary factor and theirdynamics. The result shows that fertility is the primary limiting factor when the productivity is rather low. As chemicalfertilizer input increases and the productivity promotes, water gradually becomes the primary limiting factor. Chemicalfertilizers and plastic film mulching are the two major driving forces that determine the crop productivity and its stabilityin these areas.展开更多

Some techniques, e.g., the calculus of variations, the energy analysis method, the commutativity of the products of difference operators, the decomposition of high-order difference operators, and the theory of a priori estimate, are introduced. An optimal order error estimate in the l2 norm is derived. The method is successfully used in the numerical simulation of the enhanced oil production in actual oilfields. The simulation results are satisfactory and interesting.展开更多

However, it is not enough to understand the whole picture merely from a domestic perspective. The concept of new quality productive forces was put forward due to the changes in the international environment, including the emergence of anti-globalization trends and the economic policies of some major economies that are less open than before. With the changes in the global economic concept, China's economic development needs its innovative theory. As the world's second-largest economy, China is committed to the development of new quality productive forces and will make significant contributions to global development. In theory, it shows direction for the development of new quality productive forces on a global scale. In practice, it provides experiences for other economies to develop new quality productive forces. It also helps address the common challenges facing global development. The competition between major countries in traditional fields will continue, but in the case of the development of new quality productive forces, it will show some new characteristics. It will be more reflected in the field of strategic emerging industries, the confrontation risk in major country rivalry will be reduced, and strategic planning and design will become more important.展开更多

It is required to demonstrate specificity of stability indicating methods and also provides an insight into degradation pathways and degradation products of the drug substance and helps in elucidation of the structure of the degradation products. Forced degradation studies show the chemical behavior of the molecule which in turn helps in the development of formulation and package. In addition, the regulatory guidance is very general and does not explain about the performance of forced degradation studies. Thus, this review discusses the current trends in performance of forced degradation studies by providing a strategy for conducting studies on degradation mechanisms and also describes the analytical methods helpful for development of stability indicating method.展开更多

In the present paper, we describe the repeated spark or repeat current in terms of the hidden, Non-Relativistic Longitudinal Cardinal Ampere Force which is not found yet infallible for every case. The impressive finding is the fact that these repeated sparks as we shall see, have no back-emf, but forward-emf and forward-Ampere-motive-force. The only consumption is the resistive load with the very high currents needed. This means its total energy consumption is less than the released energy-output work plus heat, plus the energy recharging the batteries. All these are in excess of the consumed input energy. This means the Repeated sparking is “over-unity” efficiency and that, using super-conductive materials, we shall have constructed the first “perpetual mobile” plus producing extra electrical energy. Several previous journals that we did not mention here their names did not dare to publish our disliked papers of very important and revolutionary results but were not able to counter argue our arguments. They preferred the silence and have not answered us at all for many years now. Even some of them were involved previously with the repeated sparking which is the same topic of our present paper.展开更多
