During cooling the temperature of the central heat source goes down slower in oil- or air-saturated sands than in water sands. Based on the theory of heat-conduction in porous media and the experimental results, we developed a new heat-conduction logging technique which utilizes an artificial heat source (dynamite charge or electric heater) to heat up target forma- tions in the borehole and then measure the change of temperature at a later time. Post-frac oil production is shown to be directly proportional to the size of the temperature anomaly when other reservoir parameters are fairly consistent. The method is used to evaluate potential oil production for marginal reservoirs in the FY formation in Song-Liao basin of China.展开更多

The model accounts for both gas and liquid phase in the same computational domain, and thus allows for the implementation of phase change inside the gas diffusion layers. The model includes the transport of gaseous species, liquid water, protons, energy, and water dissolved in the ion-conducting polymer. Water is assumed to be exchanged among three phases: liquid, vapottr, and dissolved, with equilibrium among these phases being assumed. This model also takes into account convection and diffusion of different species in the channels as well as in the porous gas diffusion layer, heat transfer in the solids as well as in the gases, and electrochemical reactions. The results showed that the present multi-phase model is capable of identifying important parameters for the wetting behaviour of the gas diffusion layers and can be used to identify conditions that might lead to the onset of pore plugging, which has a detrimental effect on the fuel cell performance. This model is used to study the effects of several operating, design, and material parameters on fuel cell performance. Detailed analyses of the fuel cell performance under various operating conditions have been conducted and examined.展开更多

Four concentrations (100 g. kg i, 50 g. kg^-1, 25 g. kg^-1 and 12.5 g. kg^-1) were prepared for each kind of extracts. Result showed that the water extracts with low and moderate concentrations accelerated the growth of collar diameter and increased biomass and root/shoot ratio of walnut seedlings. The water extracts from branches and barks with low and moderate concentrations accelerated the height growth of the seedlings, while those from leaves and roots slightly decreased the height growth of seedlings. The fact that application of water extracts of larch improved the growth of Manchurian walnut attributes possibly to the allelopathy between the two tree species.展开更多

Indigenous knowledge and adaptation are the collective information, with improvement from generation to generation. The expectation is that under community control, local expertise on biodiversity will play a significant role in natural resource management through traditional practices. This paper discusses the characteristics and application of the traditional ecological knowledge of aboriginal peoples in northeast India and its role in natural resource management. Examples are provided in two different eco-cultural landscapes, i.e., Demazong (the Buddhist eco-cultural landscape in Sikkim Himalaya) and the Apatani eco-cultural landscape in Arunachal Pradesh, which illustrate the utility value of traditional ecological knowledge in sustainable natural resource management. Both eco-cultural landscapes are indeed very complex and highly evolved systems with high levels of economic and ecological efficiencies. The paper concludes that traditional ecological knowledge systems and institutions could serve as entry points into the sustainable utilization and management of natural resources. This could be achieved through the exploration of the cultural practices of the local people and integrating useful aspects into the modern natural resource management expertise. With rapidly depleting biodiversity in the developing tropic regions, there is a greater utilization today than ever before of the value of respecting the "Sacred" as a tool towards better conservation of natural resources.展开更多

It is conducted by having questionnaires and interviews among 220 students and by analyzing the teaching materials. The findings to the study indicate that the main obstacles are caused from the following aspects: neglecting the importance of developing vocabulary in the advanced study; neglecting activating the students' directing sense and detecting sense to difficult words; low rate of word recurrence in the teaching materials; requiring distinguishing the shade of the difference between synonyms excessively and too meticulously; overemphasizing the "negative transfer" of mother tongue; and some other obstacles to the development of lexical competence.展开更多

The workshop is based on a set of theoretical concepts taken from: psychology, play therapy, and literacy theory which have been blended together to form a set of teaching approaches and lesson plan ideas that can be used in Literacy/English classes. The paper will also discuss the value of using "Story Sacks" to develop and raise levels of comprehension and understanding in extensive reading and reading programs. The application of "Soft Toy Theory" could also provide a positive social-psychological affect on the students. It is designed to creating bonding between teacher and student and student and student and to raise levels of self-esteem and enable the teachers to be able to access the thoughts and feelings of a child or young adu/t which can often be hard to discern from traditional direct question and answer sessions. "Soft Toy Theory" is a term that the author has adopted herself for using play, creativity, and art resources and soft toys to create dialogues in the Kindergarten and Elementary classroom: It is even possible to extend the use "Soft Toy Theory" to middle school, high school, and adult classrooms if the resources and topics and "tone" and tenor of teaching are appropriately adapted. Soft Toy Theory assumes that soft toys can include: actual soft toys, art resources, and other play resources: such as, sand, water, puppets, masks and clay. Story Sacks employ much of the theory that supports "soft toy usage" within the classroom. Story Sacks aim to provide inspiring resources whilst encouraging enjoyment and a greater comprehension of "real" books or "graded" readers. Additionally, Story Sacks can support extensive reading in the school and at home, and are a useful adjunct to Soft Toy Theory and supporting literacy activities in any classroom.展开更多

A total of eight phyla, 97 genera, and 310 species were found, including 232 diatom species, 45 dinoflageUate species and 33 other taxa. The phytoplankton abundances presented a significant (P〈0.001) seasonal difference with the average of 60.66x104 cells/m3. Diatoms (mainly consisting of Coscinodiscus jonesianus, Cerataulina pelagica, Skeletonema costatum, and genus Chaetoceros) dominated the phytoplankton assemblage in all seasons. We found great spatio-temporal variation in community composition based on the multidimensional scaling and similarity analysis. Canonical correspondence analysis show that temperature, nutrition, illumination, and salinity were the main variables associated with microalgal assemblage. Compared with the previous studies, an increase in phytoplankton abundance and change in the dominant species coincided with increased exploitation activities in this bay (e.g. operation of coastal power plants, intensive mariculture, tidal fiat reclamation, and industrial and agricultural development). The present findings suggest that the government should exercise caution when deciding upon developmental patterns in the sea-related economy.展开更多

They focused on the relation between ethics and two main contexts: education and research. This paper aims at discussing what ethical procedures were taken in international studies. The data were collected at ERIC (Educational Resources Information Centre) database during the first semester of 2016. As analytical categories, we used the ethical procedures established by Brazilian Applied Linguists. The contribution is addressed to both BAL and International Applied Linguists once it offers an overview about a specific topic of research (viz., ethics). As results, we observed that most of the topics presented by the Brazilian applied linguists were also covered by the research analyses. However, the social relevance was not reported properly by the data and that may be improved.展开更多

The study involved interviews with school principals and analysis of their schools' financial statements. The aim of this project is to gain a current understanding of the issues and challenges facing primary schools in a defined region (Waikato) to see whether the trends identified in national research studies, confirms the problem that schools are underfunded. The results of the current study identified the issues experienced by the Waikato schools and in most cases supported previous research findings. The findings of the current study also suggest that schools share the dilemmas associated with limited government funding and rely significantly on local funding sources to achieve their basic objectives. Although schools may be effective in the management of their school objectives, there is more government funding required to relieve the pressures and challenges.展开更多

In addition to the knowledge in daily work, study and life, some important historical materials are collected in libraries, and all of them are of important significance for studies of social development from multiple aspects. Influenced by information technology, the forms of library resources are no longer limited to books and documents, and digital resources have changed into part of the storage of library information. With the purpose of solving the problems in the current management of non-book resources, it is necessary for management personnel of libraries to actively change management model and make more scientific and sound resource management programs. Based on this point, an analysis is made by the author in this paper.展开更多

The library is one of the main information resources constructions and is an important information resource position of social construction. Computer applications in the book management, greatly improve the management efficiency of the library, and have changed the traditional management service model. Universal service network extends to every comer make reader can read everywhere, breaking the boundaries of time and space and also greatly promoting the modernization of the library. Library modernization, according to the characteristics of the objective law refers library work practices, uses modem technological conditions, rational organization of scientific management of library work, to maximize efficiency and quality and effectively complete the task library. Library essence of modem management techniques is to achieve the modernization of libraries and library management modernization. Modem library information system can be divided into three aspects of building automation libraries, library networks and digital libraries. Digital library management directly reflects a country' s level of a regional knowledge economy and information industry development, and digital network resource management in the book gradually dominates.展开更多
