Securing offshore resources development:A mathematical investigation into gas leakage in long-distance flexible pipes

Gas flexible pipes are critical multi-layered equipment for offshore oil and gas development.Under high pressure conditions,small molecular components of natural gas dissolve into the polymer inner liner of the flexible pipes and further diffuse into the annular space,incurring annular pressure build-up and/or production of acidic environment,which poses serious challenges to the structure and integrity of the flexible pipes.Gas permeation in pipes is a complex phenomenon governed by various factors such as internal pressure and temperature,annular structure,external temperature.In a long-distance gas flexible pipe,moreover,gas permeation exhibits non-uniform features,and the gas permeated into the annular space flows along the metal gap.To assess the complex gas transport behavior in long-distance gas flexible pipes,a mathematical model is established in this paper considering the multiphase flow phenomena inside the flexible pipes,the diffusion of gas in the inner liner,and the gas seepage in the annular space under varying permeable properties of the annulus.In addition,the effect of a variable temperature is accounted.A numerical calculation method is accordingly constructed to solve the coupling mathematical equations.The annular permeability was shown to significantly influence the distribution of annular pressure.As permeability increases,the annular pressure tends to become more uniform,and the annular pressure at the wellhead rises more rapidly.After annular pressure relief followed by shut-in,the pressure increase follows a convex function.By simulating the pressure recovery pattern after pressure relief and comparing it with test results,we deduce that the annular permeability lies between 123 and 512 m D.The results help shed light upon assessing the annular pressure in long distance gas flexible pipes and thus ensure the security of gas transport in the emerging development of offshore resources.

The temporal and spatial patterns and potential evaluation of China＇s energy resources development

The issue of China＇s energy supply security is not only the key problem which af- fects China＇s rapid and sustainable development in the 21st century, but also the one which international attention focuses on. Based on the notable characteristic of spatial imbalance between energy production and consumption in China, this paper takes the evolution of China＇s primary energy resources development（excluding hydropower） from 1949 to 2007 as the study object, with the aim to sum up the evolutive characteristics and laws of China＇s energy resources development in the past nearly 60 years. Then, based on comprehensive considerations of coal＇s, oil＇s and natural gas＇s basic reserves, qualities, geological conditions production status, and ecological service function of every province, this paper adopts development potential index （DP）to evaluate the development potential of every province＇s en- ergy resources, and divide them into different ranks. Conclusions are drawn as follows： （1） Generally speaking, China＇s gross energy production was increasing in waves from 1949 to 2007. From the viewpoint of spatial patterns, China＇s energy resources development has shown a characteristic of ＂concentrating to the north and central areas, and evolving from linear-shaped to ＂T-shaped＂ pattern gradually since 1949. （2） The structure evolution of China＇s energy resources development in general has shown a trend of ＂coal proportion is dominant but decreasing, while oil and gas proportions are increasing＂ since 1949. （3） At the provincial scale, China＇s energy resources development potential could be divided into large, sub-large, general and small ranks, four in all. In the future, the spatial pattern of China＇s energy production will evolve from ＂T-shaped＂ to ＂R-shaped pattern＂. These conclusions will help to clarify the temporal and spatial characteristics and laws of China＇s energy resources development, and will be beneficial for China to design scientific and rational energy development strategies and plans, coordinate spatial imbalance of energy production and consumption, ensure national energy supply, avoid energy resources waste and disorderly development, and promote regional sustainable development under the globalization back-ground with changeful international energy market.

Cultivating New-type Farmers Based on the Theory of Human Resources Development

Under the direction of theory of human resources development,this thesis analyzes the impact of rural human resources development oncultivating new-type farmers.Firstly,it increases the input of rural basic education;secondly,it reinforces the vocational education and technologytraining;thirdly,it promotes the rural medical and public health services;fourthly,it quickens the rural labor transfer.The status quo of China's ruralhuman resources has been analyzed as follows:in terms of the quantity of rural human resources,the status quo is large and quick-developed baseof rural human resources,high labor participatory rate,and constitution of low age;in terms of the quality of rural human resources,the status quois the ubiquitous low quality of rural human resources,low technological level of rural human resources,and overall low physical quality of farmers;in terms of the structure of rural human resources,the status quo is the irrational industrial structure distribution and imbalanced regional structuredistribution.The thesis also discusses the edification of theory of human resources development in cultivating new-type farmers.First,in terms ofthe control over quantity of rural human resources,it is to keep the stability of family planning policy,and expedite the transfer of rural surplus la-bor;second,in terms of promoting the quality of rural human resources,it is to bolster the development of reserve rural labor force resources,toconstruct the adult educational training system with Chinese characteristics,and to build rural primary health care system;third,in terms of adjus-ting the structure of rural human resources,it is to perfect rural human resources market,and adjust rural economical structure and talents struc-ture.

Priority-sequence of mineral resources' development and utilization based on grey relational analysis method

Generally, the sequence decision of the development and utilization of Chinese mineral resources is based on national and provincial overall plan of the mineral resources. Such plan usually cannot reflect the relative size of the suitability of the development and utilization of mineral resources. To solve the problem, the paper has selected the gift condition, the market condition, the technological condition,socio-economic condition and environmental condition as the starting-points to analyze the influential factors of the priority-sequence of mineral resources' development and utilization. The above 5 conditions are further specified into 9 evaluative indicators to establish an evaluation indicator system. At last,we propose a decision model of the priority sequence based on grey relational analysis method, and figure out the observation objects by the suitability index of development. Finally, the mineral resources of a certain province in China were analyzed as an example. The calculation results indicate that silver(2.0057), coal(1.9955), zinc(1.9442), cement limestone(1.9077), solvent limestone(1.5624) and other minerals in the province are suitable for development and utilization.

Justifying a Study on Constructing a National Human Resource Development Model as Practiced in Malaysia

The globe has been confronting a new set of challenges. Such challenges are unique to each country context. The overarching challenge, all above other challenges is, to seek appropriate knowledge as a tool and mean to resolve such challenges. A critical such knowledge to be accumulated in all days is on how to develop people or human resources. However, with the existing knowledge claims in this regard, countries have been unable to resolve such challenges. Human Development, one such knowledge claim, is too broader, and therefore, no guided protocol is suggested in finding solutions. Human Resource Development, as another such knowledge claim is too limited in scope to address broader level challenges. National Human Resource Development （NHRD） has emerged to bridge this gap, emphasising people oriented solutions to resolve country level challenges. The NHRD literature encourages NHRD country case studies, and that, justifications for starting NHRD country case studies is needed. This study justifies such a research on NHRD practices in Malaysia＇s country context, using content analysis. As a result, this study has shown higher level country challenges, derived a need of people based approach in resolving such challenges, highlighted NHRD as capable as possible in guiding to establish people development knowledge claim, and finally justified an NHRD research to be done within Malaysia＇s context to see how Malaysia practices NHRD.

Research on Resource Development Countermeasures and Environmental Governance of Cruise Tourism Enterprises in China

The development of tourism resources aims to process tourism raw materials into direct-consumption tourism products. The essence of this behavior is innovation. The theory of innovation in economics, management, sociology, oriental management, and related disciplines provided methodology for the development of tourism resources and pointed out the direction. With the development of tourism, the cruise economy has grown and the urban economy has been rapidly developed and improved. However, while cruise tourism brings economic benefits, the discharge of various waste water and exhaust gas from cruise ships of major cruise companies also brings about some environmental pollution problems. Therefore, the environmental protection issue of cruise tourism companies is a sustainable development issue. Persisting in sustainable development strategy, we attach importance to the environmental governance of the cruise tourism industry.

The Content and Approaches of Human Resource Development in Impoverished Rural Regions in the Context of Targeted Poverty Alleviation

Poverty alleviation requires knowledge support. Targeted poverty alleviation, aiming to tackle rural poverty, needs to be supported by corresponding rural human resource development. Currently, China's human resource development in impoverished rural regions is faced with some major problems; a huge population distributed over a vast area, a lack of technological and cultural attainment, obsolete concepts, obsolete technical resources, and a significant gap between rural and urban education attainment. Rural human resource development, which is geared to targeted poverty alleviation, includes a variety of impoverished rural population-oriented trainings, such as intelligence development, skills training, modern professionalism &work attitude cultivation, physical & mental health education, as well as modern lifestyle & civilized manners guidance. Targeted poverty alleviation should be equipped with mechanisms of comprehensive layout & planning, coordinated advancement of development content and implementation, and a mechanism of organization & input. The approaches to the advancement of rural human resource development are enhancing basic education, building a system of vocational education and training, raising the social security level and improving the supporting mechanisms.
