Based on the waterflooding development in carbonate reservoirs in the Middle East,in order to solve the problem of the poor development effects caused by commingled injection and production,taking the thick bioclastic limestone reservoirs of Cretaceous in Iran-Iraq as an example,this paper proposes a balanced waterflooding development technology for thick and complex carbonate reservoirs.This technology includes the fine division of development units by concealed baffles and barriers,the combination of multi well type and multi well pattern,and the construction of balanced water injection and recovery system.Thick carbonate reservoirs in Iran-Iraq are characterized by extremely vertical heterogeneity,development of multi-genesis ultra-high permeability zones,and highly concealed baffles and barriers.Based on the technologies of identification,characterization,and sealing evaluation for concealed baffles and barriers,the balanced waterflooding development technology is proposed,and three types of balanced waterflooding development modes/techniques are formed,namely,conventional stratigraphic framework,fine stratigraphic framework,and deepened stratigraphic framework.Numerical simulations show that this technology is able to realize a fine and efficient waterflooding development to recover,in a balanced manner,the reserves of thick and complex carbonate reservoirs in Iran and Iraq.The proposed technology provides a reference for the development optimization of similar reservoirs. 展开更多

The development of rural areas usually has a positive impact on the urban-rural integration. This study explores an innovative approach to stimulate rural development by proposing qualified villages as central villages that can provide basic urban services for their residents and residents of neighboring villages. This approach can contribute to overcoming the various problems that rural areas faced at the social, economic, and environmental levels. It seeks to achieve spatial sustainability of rural areas, representing a new approach by integrating urban development methods to revitalize rural villages. The study analyzed 15 villages belonging to Abbasiya District of AL Kufa City in the Najaf Governorate of Iraq. Based on the GIS techniques and the analysis of urban service indicators(village population, percentage of urban building materials used in villages, distance between village and health centers, distance between village and main roads, nature of economic activity, distance between village and educational institutions, distance between village and drinking water sources, number of communication towers, and distance between village and urban administrative center), this study proposed that Abu Gharb and Albu Ghraib can served as central villages in Abbasiya District in the future. This study establishes a new rural spatial structure to achieve rural sustainable development, improves the development status of rural areas, and provides a theoretical basis for the government and relevant institutions to use urban service indicators, achieving rural sustainable development and formulating relevant development policies in Abbasiya District. 展开更多

Balancing urban and rural comprehensive reform is the major reform and developmental strategy of China. On the basis of the concept and theory of balancing rural and urban reform, the two national pilot cities Chengdu, Chongqing and several provincial pilot cities including Ningbo, Yangzhou, Shaoxing and Zigong are compared. The experiences and connotation of balancing urban and rural areas are concluded from the following four aspects. Firstly, scientific plan is a prerequisite; secondly, promoting "three collections" is the core; thirdly, developing people's livelihood is the basis; fourthly, organization security is the key. 展开更多

To implement the previously formulated principles of sustainable economic development, all solutions of the linear system of equations and inequalities, which are satisfied by the vector of real consumption, are completely described. It is established that the vector of real consumption with the minimum level of excess supply is determined by the solution of some quadratic programming problem. The necessary and sufficient conditions are established under which the economic system, described by the “input-output” production model, functions in the mode of sustainable development. A complete description of the equilibrium states for which markets are partially cleared in the economy model of production “input-output” is given, on the basis that all solutions of system of linear equations and inequalities are completely described. The existence of a family of taxation vectors in the “input-output” model of production, under which the economic system is able to function in the mode of sustainable development, is proved. Restrictions were found for the vector of taxation in the economic system, under which the economic system is able to function in the mode of sustainable development. 展开更多

The urban and rural areas are regarded as two major components of the regional economic system. Only through joint balanced development of the two can we achieve overall economic optimization and social welfare maximization. But the great social division of labor has separated urban areas from rural areas,which casts the shadow of city-oriented theory on cooperative relations between urban and rural areas. Mutual separation between urban and rural settlements and independent development trigger off a range of social problems. We must undertake guidance through rational development path of urban-rural integration,to eliminate the phenomenon of urban-rural dual structure,and promote the sustainable development of population,resources and environment in urban and rural areas as soon as possible. 展开更多

The urban-rural networking is a reality and an inexorable trend of development. As a physical existence, the urban-rural networking reflects a result of the interaction between cities and rural areas; it is a necessary and sufficient condition for sustaining progress of cities and rural areas. As an objective developmental tendency, it reflects an urban-rural regional economic process. The author briefly analyzes two contradictory urban-rural developmental views, and puts forward a concept of the mode of urban-rural networking development. The author also analyzes the mode from the perspectives of economics and philosophy. 展开更多

Its philosophy has a long history and development process in urban planning. The concept of jobs-housing balance generally refers to that the number of employed people is roughly equal to the number of occupants within a certain range. This kind of balance is conducive to reducing the commuting time and the change of transportation mode on the way that the employed people spend at work. The realization of jobs-housing balance not only helps to optimize the structure between residence and employment in the region but also is conducive to improving the work enthusiasm and work efficiency of the employed in the region and reducing the commuting costs of workers in the region. In addition, the relegalization of jobs-housing balance also has a certain impact and effect on alleviating the traffic congestion and improving the environment of the region. In summary, the realization of jobs-housing balance has a multi-faceted impact on the development of a city, and promoting the balance between occupation and housing is conducive to promoting the development of the city. The realization of jobshousing balance involves many areas. In this article, In this article, the development history of jobshousing balance is sorted out from perspectives of real estate development and management and urban planning, and its development enlightenment is discussed. 展开更多

There exist diferences between urban-rural financial systems,Generally,the development of unban financial industry has absolute advanages compared with rural financial industry.According to the Matthew Effect,the financial resources will flow into cities for higher benefit ,so rural areas are unable to obtain absolute advantages However,relative advantage theory of the comparative advantage theory of the comparative advantage theory provides an lmportant way to observe res[ectove advamtage of both city and country.Therefore,there are comparative advantages for the development of financial industry in both urban and rural areas.The respective comparative advantages of urban-rural financial systems will supply greater efficiency than that in current dual puttern condition.Closely connected with China's financial development and reform and the fact of recreation of urban-rural financial system,this paper tries to explain the comparative advantage of the urban-rural financial systems.The anaalysis of the comparative advantage between urban and rural finance is the clue for the bonndary between urban-rural financial systems.This paper analyzes the current situration of urban-rural financial system.Then it proposes some views and suggestions on how to develop and maintain these two systemw as well as how to promote their coordinative development. 展开更多

Food must supply a balance of nutrients to support both brain and body.The human brain makes us uniquely human.Essential fatty acids are part of the metabolic pathways that define tissue structure and function.Omega-6(O6)linoleic acid(LA6)has long been known to be required for skin structure,and as a precursor for inflammatory,thrombotic,immune,and other signaling molecules.Omega-3(O3)alpha-linolenic acid(ALA3)and particularly its long chain product docosahexaenoic acid(DHA3)has a key structural role in the brain,retina,and related neural tissue.In the 20 th century western world,inexpensive,high quality oils primarily from LA6-rich/O3-poor vegetable seed oils became dominant fats produced by the food industry.Provision of LA6-rich/O3-poor oils as the sole source of fat in the diets of pregnant animals causes O3 deficiency and poor brain development,primarily because high LA6 antagonizes metabolism of all O3,creating an artificial metabolic demand for O3.Data developed over the last 2~3 decades show that provision of low LA6 combined with preformed DHA3 optimizes brain function.Recent studies emphasize the importance of nutrition to support brain development,with newer findings showing particular importance of fatty acid balance in malnourished children.The World Health Organization(WHO)through the Codex Alimentarius(“Code for Food”)is increasingly recognizing the primacy of brain health and in part on that basis recently acted to recommend balanced fat for Ready-to-Use-Therapeutic Foods used to treat children with severe acute malnutrition.Similar principles are likely to be important in older persons.Industry now has the tools to adjust the composition of oils to support brain health throughout the life cycle. 展开更多
