background continuous epidural analgesia with catheterization is a useful technique, because it has a wide adaptation range and provides prolonged analgesia. problems that may arise from long-term epidural analgesia are changes in the analgesic area, duration of analgesia and catheter-related problems. few articles have evaluated gradual changes of long-term epidural analgesia. in the animal mo...

An undergraduate engineering internetworking learning environment that presents both internetworking principles and laboratory experimentation is described. The learning environment uses the source code availability of the Linux operating system as a case study of the implementation issues and ramifications of internet networking infrastructures. Laboratory use of experimentation with internetw...

T his manuscript describes a ‘‘dry laboratory’’ using the ‘‘virtual rat’’ to help students understand the hormonal regulation of gastrointestinal function. The laboratory was modeled after a recent exercise that used the virtual rat to teach basic endocrine physiology. The virtual rat concept avoids the many obstacles associated with animal experimentation (for example, lack of adequate animal ...

The COVID-19 pandemic has forced analytical chemistry educators in Thailand to change methods of teaching and learning new normal ones. Higher education faced additional challenges because a lack hands-on experiments an increasing number students foundation courses being hindered from practicing skills. This work aimed develop Lab-at-Home (LAH) for normal, experimentation. LAH implemented green...

mathematical simulation of flow toward drains is an important and indispensable stage in drainage design and management. many related models have been developed, but most of them simulate the saturated flow toward drains without a due consideration of the unsaturated zone. in this study, the two dimensional differential equation governing saturated and unsaturated flow in porous media is numeri...

Remote experimentation helps to overcome restrictions in time and space. In local experimentation students usually work together in groups of two or more. This learning paradigm is often called collaborative learning. This paper presents a Web-based approach to collaborative remote experimentation. The collaborative environment introduced here allows experimentation in a team. The group is able...

Experimentation has always been an essential ingredient to sustain the learning activities in engineering education. During traditional laboratory sessions, a huge amount of work is carried out by the assistant who is in charge of supporting and evaluating the students. In a Web-based experimentation setting students ask for more feedback while they work on simulation or remote manipulation. We...
