摘要：This research is an experimental research survey with the purpose of studying the cultural tourism activity originated from ＂local wisdom＂ within Phra Nakhon Si Ayutthaya province in Thailand to be applied as a creative cultural tourism activity. The population of this study comprises 305 Thai and foreign tourists, divided into two groups, namely, 205 tourists as a sampling survey group and 100 tourists as an experimental group. The research tools used are a questionnaire and designed satisfaction assessment. The data were analyzed through the frequency, percentage, mean, standard deviation test, F-test, t-test, and one-way analysis of variance （ANOVA） with the statistical analysis program. The study showed that the appropriate activities applied from a local wisdom chosen by tourists to be studied were 10 from 20 activities through the questionnaire for ranking the piquancy of each activity from the tourist group. All the 10 activities were studied in this experimental research within the sampling group which consists of Thai and foreign tourists by allowing them to practice in a real situation and assessing their satisfaction in each activity. The assessment reveals that these 10 activities were considered to be interesting and the satisfaction level was extremely high, indicating that the activity applied from the local wisdom studied in this research is appropriate to be used as a creative cultural tourism activity in Phra Nakhon Si Ayutthaya province later in the future.

摘要：苯胺是一种使用广泛但具有高毒性的化学原料,对环境安全和人类健康有巨大的潜在威胁。因此,对苯胺的检测具有重要的应用价值。本文设计并合成了一种可对苯胺进行选择性检测的氰基二苯乙烯衍生物(CN-DBE)荧光探针材料。通过光致发光光谱和数值模拟等方法对CN-DBE的聚集诱导发光性质、传感性能和检测机理进行了详细研究。结果表明,基于光诱导电子转移机理,CN-DBE可实现对苯胺的高选择性、定量、快速检测。此外,利用浸渍法制备了相应的CN-DBE试纸,可实现对苯胺的可视化检测,提供了一种廉价且简单的苯胺泄漏检测方法。

摘要：This paper presents a real-time battery management unit designed by applying the Coulomb counting method and intended for use in an integrated renewable energy system for PV-Hybrid power supply. Battery management is required to stabilize hybrid systems and extend battery lifetimes. The battery management unit is divided into three main stages. Firstly, analysis of the basic components of the battery type used in the system is considered. Secondly, the state of charge (SOC) estimation method and the deterioration factor of the battery are analyzed. Finally, the overall battery management system, including a computer-based measurement and control unit, is constructed. The control system displays real-time information through LabVIEW 8.5 by estimating the state of charge through various measurements. The system will issue alerts when malfunctions are detected, and the operator can analyze and react to the system in real time to stabilize the system and extend the battery lifetime.

摘要：背景:发展并使用一种用于研究结核分支杆菌基因差异的聚合酶链反应(PCR)设计:结核分支杆菌H_(37)Rv的两个多态性DNA片段被鉴定和测序。然后引物被设计以用于对两个多态性片段同时进行扩增。该方法被用于研究179例临床结核菌分离株,这些菌株以前曾用IS6110的Southern杂交鉴定。结果:两个多态性片段均含有直接重复序列。其中一个片段的直接重复序列位于α-异丙基苹果酸酯合成酶基因的编码序列之间。179个菌株的两个片段经过扩增后,PCR产物的40个型能够被鉴定。该方法能够将38个IS6110单带菌株区分为23个型。属于北京家族的菌株中的大多数具有与H_(37)Rv相同的PCR产物。Nonthaburi组成员的PCR产物彼此间是相似的。结论:这些结果符合北京家族和Nonthaburi组成员起源于两个共同祖先的假说。该PCR方法可能有助于对含IS6110单拷贝的结核菌菌株进行区分。
