Material research for environmental sustainability in Thailand: current trends

This article covers recent developments of material research in Thailand with a focus on environmental sustainability. Data on Thailand’s consumption and economic growth are briefly discussed to present a relevant snapshot of its economy. A selection of research work is classified into three topics, namely, (a) resource utilization, (b) material engineering and manufacturing, and (c) life cycle efficiency. Material technologies have been developed and implemented to reduce the consumption of materials, energy, and other valuable resources, thus reducing the burden we place on our ecological system. At the same time, product life cycle study allows us to understand the extent of the environmental impact we impart to our planet.     

1989年以来档案文化研究文献定量分析

1989年以来档案文化研究渐渐趋热，研究偏重社科理论，涉及面广，研究者及机构以高校及档案行政管理机构居多。成果有限，整体水平尚低。研究内容主要集中在档案文化研究概况、档案文化基本理论研究、多视角下的档案文化研究、历代档案文化研究、外国档案文化、档案文化产业、档案文化应用方式、档案文化建设存在的问题、档案文化建设的途径与方法、局馆档案文化建设等方面。     

老井复查评价技术在浅层油藏中的研究与应用

本文以靖安地区浅层老井为例,利用钻井、录井、测井、取心等资料,结合现代测井解释评价技术,对受当时技术条件限制被误判的储层进行再分析研究。制定可行的复查评价标准与流程,确定出油下限,优选补孔潜力井,并结合精细地质研究成果筛选建产目标区,达到挖潜增效和滚动增储的双重目的。对老区日后寻找新储量进行勘探开发具有十分重要的意义。

Formal Approach to Workflow Application Fragmentations Over Cloud Deployment Models

Workflow management technologies have been dramatically improving their deployment architectures and systems along with the evolution and proliferation of cloud distributed computing environments. Especially, such cloud computing environments ought to be providing a suitable distributed computing paradigm to deploy very large-scale workflow processes and applications with scalable on-demand services. In this paper, we focus on the distribution paradigm and its deployment formalism for such very large-scale workflow applications being deployed and enacted across the multiple and heterogeneous cloud computing environments. We propose a formal approach to vertically as well as horizontally fragment very large-scale workflow processes and their applications and to deploy the workflow process and application fragments over three types of cloud deployment models and architectures. To concretize the formal approach, we firstly devise a series of operational situations fragmenting into cloud workflow process and application components and deploying onto three different types of cloud deployment models and architectures. These concrete approaches are called the deployment-driven fragmentation mechanism to be applied to such very large-scale workflow process and applications as an implementing component for cloud workflow management systems. Finally, we strongly believe that our approach with the fragmentation formalisms becomes a theoretical basis of designing and implementing very large-scale and maximally distributed workflow processes and applications to be deployed on cloud deployment models and architectural computing environments as well.

Visualization analysis of heart diseases using two‐dimensional electrocardiogram sequences

During the last years, there have been large advances in the understanding of cardiac mechanics, and in particular shape, motion and deformation. However, it is important to comprehend how these features interrelate and how they can be interpreted to refine the clinical diagnosis. The goal of our study is to illustrate the use of two‐dimensional ultrasound cardiac motion sequences on some typical cardiac pathologies. The method is applied to preprocessed data from two‐dimensional ultrasound sequences of four different subjects, namely, two healthy volunteers, one patient with left ventricular mechanical dyssynchrony from the left bundle branch block, and one patient with hypertrophic cardiomyopathy. The interpretation based on these features is corroborated with other analyzing techniques such as electrocardiogram and visual interpretation by experienced clinical observers. The proposed method realizes a computer program, which allows the user to easily obtain and visualize information about myocardial shape, motion (displacement and velocity), and deformation (strain) along the left ventricle myocardium wall during the cardiac cycle.     

聚六亚甲基胍杀菌剂的制备及其在海洋油田中的应用

以己二胺和盐酸胍为原料,合成一种聚六亚甲基胍杀菌剂(BHS-49)。与其他主流杀菌剂进行对比,侧重研究其杀菌能力,BHS-49加注质量浓度30mg/L时,SRB含量最低,平均值为25.5个/mL。在海上油田开展现场试验,结果显示,各级检测点细菌含量明显降低,FPSO缓冲罐出口细菌含量降低至6个/mL。同现场在用杀菌剂BHS-29相比,SRB含量降低76%,满足排放要求。与此同时,杀菌剂BHS-49加注期间,现场流程稳定,各监测点出口水质未出现波动。     

长沙太平街湘绣产品的市场调查与分析

长沙是湘绣的发源地,集湘绣的研发、生产、销售于一体,拥有着独特的湘绣文化。太平街坐落于长沙市老城区南部,是一条商业繁荣、游客众多的文化老街,主要以销售长沙当地特产、传统手工艺品、特色小吃等为主,极具湖湘文化魅力,吸引了许多外来游客。笔者以太平街为研究范围,对太平街区域内的湘绣销售情况进行了问卷调查,调查显示,太平街区域内的湘绣产品销售情况与湘绣产品的种类和游客群的构成特征关系密切。基于上述调查结果,笔者对当下的长沙地区湘绣销售的前景和未来湘绣文化产品的推广,进行了分析并提供了新的思路。
