Development of Productive Forces and the Changes of Rural President's Consumption Concept

The developmental status of productivity in Chinese rural area is introduced. 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.

Influences of greenhouse effect on agricultural production in China

An obvious warming in China induced by doubled carbon, dioxide as simulated by the climatic models have been found. It is also noticed that there might be drying or wetting in some parts of China induced by doubled CO2 as simulated by the general circulation models(GCMs). Agricultural productivity mainly depends on the temperature, rainfall and soil moisture in China. The changes of agricultural productivity in the different parts of China induced by doubled CO2 have been estimated in this paper. It is shown that the greenhouse effect might cause increasing production in some parts of China and decreasing production in other parts of China.

The Institutional Framework of Common Prosperity in the Process of Chinese Modernization

The report to the 20th CPC National Congress makes it clear that achieving common prosperity for all is an essential requirement of Chinese modernization,and that China has come to a historical period when concrete measures can be taken to promote common prosperity with a well-researched and effective system.In the new journey of Chinese modernization,we must correctly understand productive forces and production relations,properly handle the relation between efficiency and fairness,and promote common prosperity with sound systems.Therefore,efforts must be made to create an institutional framework of common prosperity that involves three pillars—socialism with Chinese characteristics as the fundamental system,improving the efficiency and vitality of productive forces as the basic system,and preserving fairness and adjusting productive relations and income distribution as the foundational system.To succeed,we must do the following three things.First,we should uphold the system where the Party leads the country,and all our work and the people run the country.Second,we should improve the basic economic system in which public ownership is the mainstay,the high-level socialist market economy,related systems,to promote high-quality economic development,and auxiliary systems to realize common prosperity with the digital economy.Third,we should perfect the institutional arrangements related to primary,secondary,and tertiary income distribution.

Establishment of inherent stability of pramipexole and development of validated stability indicating LC-UV and LC-MS method

Pramipexole belongs to a class of nonergot dopamine agonist recently approved for the treatment of early and advanced Parkinson＇s disease.A validated specific stability indicating reversed-phase liquid chromatographic method has been developed for the quantitative determination of pramipexole in bulk as well as in pharmaceutical dosage forms in the presence of degradation products.Forced degradation studies were performed by exposition of drug to hydrolytic（acidic and basic）,oxidative and photolytic stress conditions,as defined under ICH guideline Q1A（R2）.Significant degradation was observed under hydrolytic,oxidative and photolytic conditions and the degradation products formed were identified by LC-MS.

Synchronizing~① Your Sales and Production Forces

在工厂和企业中,生产人员专管生产;销售人员负责销售,这是显而易见的事实。但是美国McGladrey ＆ Pullen公司的高级顾问(制造和销售)RonPachura认为,由于生产和销售人员的职能观点不同,他们往往单独地和独立地开展各自的活动,经常引发两者之间的紧张关系和冲突。这会损害工厂的收益,甚至铸成大错。例如:Boeing finally recognized its blunder in 1997 and…reported acharge of $1.6 billion and forecast another $ 1 billion loss for 1998 as a direct resultof its mistakes.触目惊心！ 如何才能防止出现类似的错误?这位顾问认为:首先要密切地监控工厂的关键统计资料;管理部门要对这些资料进行评价和分级,明确最主要的成功因素;还必须在生产和销售之间建立合适的渠道,以协调现有的生产能力与市场需求。这样就能化解两者之间的紧张状态。生产者的主要目的不仅仅是生产,而是获得利润。一旦双方认识到这一事实,工厂的经营和有关人员的经济状况将会好转。

Generalized Kutta–Joukowski theorem for multi-vortex and multi-airfoil flow with vortex production——A general model

By using a special momentum approach and with the help of interchange between singularity velocity and induced flow velocity, we derive in a physical way explicit force formulas for twodimensional inviscid flow involving multiple bound and free vortices, multiple airfoils, and vortex production. These force formulas hold individually for each airfoil thus allowing for force decomposition, and the contributions to forces from singularities（such as bound and image vortices,sources, and doublets） and bodies out of an airfoil are related to their induced velocities at the locations of singularities inside this airfoil. The force contribution due to vortex production is related to the vortex production rate and the distance between each pair of vortices in production, thus frameindependent. The formulas are validated against a number of standard problems. These force formulas, which generalize the classic Kutta–Joukowski theorem（for a single bound vortex） and the recent generalized Lagally theorem（for problems without a bound vortex and vortex production） to more general cases, can be used to identify or understand the roles of outside vortices and bodies on the forces of the actual body, optimize arrangement of outside vortices and bodies for force enhancement or reduction, and derive analytical force formulas once the flow field is given or known.

Force Generation Profiles of Para-Nordic Sit-Skiers Representing Different Physical Impairments

Purpose To biomechanically profile force generation connected to the complex role of the trunk in double poling in a rep-resentative sample of Para-Nordic sit-skiers.Methods Twelve male World Cup Para-Nordic sit-skiers(sport classes:LW10-12)were skiing on flat snow terrain at submaximal speed of 4.5 m/s(~73% max imum speed).2D video(50 Hz)and pole force analyses(1000 Hz)were performed synchronously,examining angle,force and cycle characteristics to analyse the role of the trunk in generating propulsion.Results LW10-11.5 skiers lost between 21%and 4%propulsive force versus LW12 athletes only due to different geomet-rics of the trunk and pole angle at an equal axial pole force.While LW10-11 skiers indicated trunk extension or position maintenance during pole thrust,LW11.5-12 skiers showed strong trunk flexion combined with smaller pole angles to the ground.Hence,LW11.5-12 skiers could create larger propulsive forces and therefore greater cycle lengths at lower cycle rates at the same speed.Maximum speed increased from LW10 to LW12 and was significantly correlated to trunk flexion range of motion(r=0.63)and cycle length(r=0.59).Trunk flexion ROM showed a significant relationship to the impulse of propulsive force(r=0.63)and pole angle to the ground(r=−0.76)(all P<0.05).Conclusion The impact of impairment on the force production profiles and its physiological-biomechanical consequences need further investigation also in other terrains and at wider spectrums of skiing speeds.The evident problem of low numbers of LW10-11 skiers in World Cup needs creative future solutions for research.

A NUMERICAL STUDY ON MECHANISM OF S-STARTS OF NORTHERN PIKE (ESOX LUCIUS)

Northern pike is regarded as a specialist in swimming acceleration. The force production mechanism of northern pike, Esox lucius, during its predation S-starts was numerically studied in this article. The problem was reasonably simplified to a loose-coupling problem of fish swimming dynamics and hydrodynamics just in the swimming direction. The approach involved the simulation of the flow by solving the two-dimensional unsteady incompressible Navier-Stokes equations and decribing the fish motion dynamics based on Newton＇s Second Law. Visualizations of flow fields and vortex structures were performed. The results show that the large acceleration is obtained mainly in the first undulatory cycle in which the amplitude increases. In the second cycle, a couple of vortices are generated and induce a jet. In the third cycle, the jet is strengthened by the mergence of the vortices in the same direction. Through discussing the effects of various controllable factors on the swimming performance, it is found that the actual locomotion mode of the northern pike in nature is just the best choice.
