Much remains to be done before the small scale, process level understanding of ecosystem responses to global change can be reliably translated to larger scales. The paper reviews the status of scaling issues and tries to find how to extrapolate our observations and our findings at site scale up to regional scale and provide ecological information and interpretations at the regional scale. An integrated approach to scaling-up from site to region is proposed combining hierarchical theory, landscape ecology, remote sensing, geographical information system (GIS) with process/mechanistic modeling. Remote sensing and GIS will play key roles in spatial analysis, integration as well as cross scale modeling.展开更多

Accordingly, intelligent decision-making through multi-objective optimization has been proposed as an efficient method for human-centered manufacturing. However, previous vast researches on optimization have been mainly focused on optimization theory and optimization techniques and paid little interests on the process of problem formulation itself. In this paper, therefore, the authors present a total framework for supporting multi-objective decision making. Then, the authors try to solve the formulated multi-objective optimization problem that involves both qualitative and quantitative performance measures as a general consequence from the above procedure. Taking especially quality as a qualitative measure, the authors gave a new idea to evaluate the quality quantitatively. Additionally, to facilitate the portability of the proposed method in multidisciplinary decision-making environments, the authors implement the proposal algorithm in an Excel spreadsheet and validate the effectiveness of the approach through a case study.展开更多

Many previous standard methods,such as precedent type analysis,rock classification,analytic method stress-based,basic numerical methods (BEM,FEM,DEM,hybrid),and their extended numerical methods (fully coupled) to be developed,can be selected respectively or integrated accordingly. It is alternative to develop basic/fully integrated system,and internet-based approaches. These novel methods can also be selected or integrated each other or with the standard methods to perform rock mechanics analysis. Some key techniques to develop these alternative methods are discussed. It may focus in future on developing fully integrated systems and internet-based approaches. Developing an environmental,virtual facility/space shall be firstly done for this collaborative research on internet.展开更多

In the integrated approach, the development of a solvent extraction （SX） flow sheet is done in the following order： 1） Definition of the process： composition of the feed, specification of the product, minimum yield, etc.; 2） Selection of the solvent（s） and studying its chemical and physical properties; 3） Design of the optimal flow sheet using a computer simulation; and 4） Combination of process definition and the results of both the simulation and the laboratory experiments for every battery yields the right type of equipment. Experimental proof of the recommended flow sheet, in the adequate equipment, follows-first in a bench-scale, and then in a full scale pilot or demonstration plant. Following of these simple rules ensures a successful development of the process.展开更多

To understand the level of new production in the sea area studied better, an estimate of new production must be obtained in large spatial and temporal scales. The ~234Th/ ~238U disequilibrium is an effective method for the study of new production. Two sampling strategies, vertically integrated sampling ap proach based on trapezoidal integration principle and discrete layer sampling approach, were compared in the studies of the xiamen Bay and the northern South China Sea. The scavenging fluxes and removal fluxes of ~234Th and the residence times for dissolved and particulate ~234Th were calculated. The coinci dent results from two Sampling approach suggest that vertically integrated sampling approach is not only effective and reliable, but also significantly reduces the number and volume of samples. It allows us to study new production by ba ^(234)Th - ^(238)U disequilibria in large spatial scale.展开更多

Previous studies have revealed that miRNAs play key roles in multiple biological processes, such as growth and development in both animals and plants. Computational identification is an efficient method for miRNA prediction in organisms with a reference genome before high-throughput miRNA sequencing experiments. In this study, we employed an integrated strategy combining the homology-based and ab initio approaches to predict miRNAs from the genome and transcriptome of large yellow croaker, one of the most commercially important marine fish in China and East Asia. A total of 418 miRNA molecules, including 287 miRNAs by the homology-based method and 131 miRNAs by the ab initio approach, were identified for large yellow croaker. Additionally, 16 053 target genes were predicted and annotated for Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) databases. Meanwhile, we analysed single nucleotide polymorphisms(SNPs) around large yellow croaker miRNA and found that the miRNA seed regions were significantly less prone to mutations, indicating that the miRNA sequences were under strict natural selection based on their essential regulation functions in living cells. Twenty-two SNPs were identified in large yellow croaker miRNA seed regions, which dramatically influenced the miRNA-gene regulation networks. This is the first reported miRNA detection from both the genome and transcriptome using the integrated strategy for large yellow croaker species, and the miRNA and SNP analyses in this work provide important resources and a reference for subsequent miRNA functional investigations in large yellow croaker.展开更多

In treatment group, patients were treated with 1 ） medication （ Prednisone, Dipazol, etc） and TDP （“special electromagnetic spectrum”） plus ultrashort irradiation in the early stage;2） TDP plus ultrasonic wave irradiation and acupuncture of Yangbai （阳白 GB 14） to Yuyac （鱼腰EX-HN 4, penetration needling）, etc in the medium stage; 3） medium-frequency irradiation and electroacupuncture （EA） of muscle motor joints and acupoints （GB-14, etc）. Patients of control group were treated with conventional acupuncture therapy （GB-14, etc）. Results： After treatment, of the 2 240 patients in treatment group, 2 072 （92.5%） were cured, 120 （5.3%） effective, 33 （ 1.5% ） improved, and 15 （0.7%） failed. The total effective rate was 99.3%. Of the 75 cases in control group, 46 （61.3%） were cured, 16 （21.3%） effective, 9 （12.0%） improved, and 4 （5.4%） ineffective. The total effective rate was 94.6%. The cure rate and the total effective rate of treatment group were significantly higher than those of control group respectively （x^2=29.379, P〈0.01; x^2 =5. 716, P〈0. 025）. Conclusion： The therapeutic effect of integrated approaches （medication, acupuncture, electromagnetic ＋ ultrashort wave ＋ ultrasonic wave ＋ medium-frequency wave irradiation） is significantly superior to that of simple acupuncture therapy in treating peripheral facial paralysis.展开更多

In particular, the requirement of such planned housing areas has not matched public service provided by the infrastructure. On not only physical but also social aspect of local communities of this kind of housing area have a lot of problems while it also has a lot of good characteristics. A representative one is that age of the tenants is rising very swiftly and it makes the local community imbalanced. Nowadays many countries including Japan have tackled problems concerning housing estates constructed during the mass housing era and try to search for ways to reactivate so-called new town areas by utilisation of existing environmental resources such as building stock and ample green open space. In Japan many elemental technologies have been developed in order to utilise existing building stock. However, how to combine these technologies and new holistic methods for reactivation are still underdeveloped. Therefore, it is very important to fred these ways and to make a comprehensive plan for rehabilitation of these areas. The first purpose of our study is to develop and clarify how to organise and integrate many kinds of elemental techniques and the holistic measures for the improvement of both social and physical environment in suburban mass housing estates. Subsequently we try to reorganise proper relations between human settlements and the various service provision for those regions. Our last focus is put on searching for new ways to raise the value of existing housing environment.

There are certain differences between rural sewage treatment and urban sewage treatment. Rural sewage treatment will be affected by natural conditions, customs and other aspects. Under the continuous promotion of rural revitalization strategy and beautiful countryside construction policy, relevant departments should pay attention to the sewage problem in rural areas. In order to solve the problem of sewage in rural areas, sewage treatment facilities can be built to promote the development of sewage treatment in rural areas towards a scientific, standardized and systematic direction, so as to ensure the orderly development of sewage treatment in rural areas.展开更多

The approaches refer to the Kirchhoff method, the Ffowcs Williams and Hawkings （FW-H） method of the permeable integral surface and the Curle method that is known as a special case of the FW-H method. The first two approaches are used to compute the noise generated by the core flow region where the energetic structures exist. The last approach is adopted to predict the noise specially from the pressure perturbation on the wall. A new way to con- struct the integral surface that encloses the core region is proposed for the first two methods. Considering the local properties of the flow around the complex object-the actual wing with high-lift devices-the integral surface based on the vorticity is constructed to follow the flow structures. The surface location is discussed for the Kirchhoff method and the FW-H method because a common surface is used for them. The noise from the core flow region is studied on the basis of the dependent integral quantities, which are indicated by the Kirchhoff formulation and by the FW-H formulation. The role of each wall component on noise contribution is analyzed using the Curle formulation. Effects of the volume integral terms of Lighthill＇s stress tensors on the noise pre-diction are then evaluated by comparing the results of the Curle method with the other two methods.展开更多

文摘Intense anthropogenic exploitation has altered distribution of forest resources. This change was analyzed using visual interpretation of satellite data of 1979, 1999 and 2009. Field and interactive social surveys were conducted to identify spatial trends in forest degradation and data were mapped on forest cover and land use maps. Perceptions of villagers were compiled in a pictorial representation to understand changes in forest resource distribution in central Himalaya from 1970 to 2010. For- ested areas were subject to degradation and isolation due to loss of con- necting forest stands. Species like Lantana camara and Eupatorium adenophorum invaded forest landscapes. Intensity of human pressure differed by forest type and elevation. An integrated approach is needed to monitor forest resource distribution and disturbance.

However, of the five items of CET-4 （listening, reading, vocabulary, cloze and writing）, writing remains the most difficult. Some new methods and activities are needed to maximize the efficiency of traditional methods and keep students interested in this course. This paper provides a step-by-step description of an integrated approach and activities in a writing course for non-English major students, which combines reading with writing and makes teaching writing become an integrated and interesting process.
文摘With the integrated development of urban and rural areas, the living environment in rural areas has been greatly improved. There are certain differences between rural sewage treatment and urban sewage treatment. Rural sewage treatment will be affected by natural conditions, customs and other aspects. Under the continuous promotion of rural revitalization strategy and beautiful countryside construction policy, relevant departments should pay attention to the sewage problem in rural areas. In order to solve the problem of sewage in rural areas, sewage treatment facilities can be built to promote the development of sewage treatment in rural areas towards a scientific, standardized and systematic direction, so as to ensure the orderly development of sewage treatment in rural areas.

文摘Three surface integral approaches of the acoustic analogies are studied to predict the noise from three concep- tual configurations of three-dimensional high-lift low-noise wings. The approaches refer to the Kirchhoff method, the Ffowcs Williams and Hawkings （FW-H） method of the permeable integral surface and the Curle method that is known as a special case of the FW-H method. The first two approaches are used to compute the noise generated by the core flow region where the energetic structures exist. The last approach is adopted to predict the noise specially from the pressure perturbation on the wall. A new way to con- struct the integral surface that encloses the core region is proposed for the first two methods. Considering the local properties of the flow around the complex object-the actual wing with high-lift devices-the integral surface based on the vorticity is constructed to follow the flow structures. The surface location is discussed for the Kirchhoff method and the FW-H method because a common surface is used for them. The noise from the core flow region is studied on the basis of the dependent integral quantities, which are indicated by the Kirchhoff formulation and by the FW-H formulation. The role of each wall component on noise contribution is analyzed using the Curle formulation. Effects of the volume integral terms of Lighthill＇s stress tensors on the noise pre-diction are then evaluated by comparing the results of the Curle method with the other two methods.
