Describes a simple inexpensive circuit which can be used to quickly demonstrate the basic function and versatility of the solid state diode. Can be used to demonstrate the light-emitting diode (LED) as a light emitter, temperature sensor, light detector with both a linear and logarithmic response, and charge storage device. (JRH)

Explores the benefits of including high-brightness Light Emitting Diodes (LEDs) for emergency systems and its use in residence halls. LED emergency lighting options and their qualifications are also highlighted.(GR)

Physically-based rendering (PBR) concept is widely use nowadays in 3D rendering works, this concepts interested in the ray of light for describes the interaction of light and materials. Understanding the principles of PBR can be easier to adjust shader parameters to be realistic, react correctly to changes in lighting condition and also giving the…

An experiment related to the measurement of fluorescence lifetime for an undergraduate instrumental analysis or physical chemistry laboratory that highlights relative rates of electronic transitions in molecules and introduces students to data collection of a pulsed signal is illustrated. The experiment of the long fluorescence lifetime of…

This article explores the library space needs and wants of graduate and undergraduate students at a medium-size state University in Southwest Florida. The researcher conducted a sequential explanatory mixed methods study in which they administered a survey to all currently enrolled graduate and undergraduate students at the university and followed…

The likelihood of teaching a student with autism spectrum disorder (ASD) has steadily increased over the past two decades. However, the practical information about working with students with ASD has not increased at a similar rate. Teachers may therefore be unaware of simple modifications they can make to their classrooms to meet the needs of…

Many academic libraries renovate physical spaces to address the needs of the 21st century learner. This study presents the assessment tools used to evaluate the use of space prior to a branch library renovation as well as results of two post-renovation assessments to examine the success of the project. The pre-renovation survey showed that library…

Objective: It is important for college students to engage regularly in physical activity. While psychological factors, such as motivation, are likely to increase attendance at fitness facilities, positive perceptions of the fitness facility (e.g., the type of classes offered) might also influence use of a fitness facility. Participants: Data were…

The wavelength of the light emitted by a light-emitting diode (LED) is intimately related to the band-gap energy of the semiconductor from which the LED is made. We experimentally estimate the band-gap energies of several types of LEDs, and compare them with the energies of the emitted light, which ranges from infrared to white. In spite of…

Although large international studies have defined Norway as one of the most secular countries in the world, Christian folk high schools in Norway have experienced record high attendance. This paper presents case studies of the religious education (RE) and practices of two Christian folk high schools in Norway. A survey shows that students at these…

Schools create an inclusive environment and cultures and enact inclusive practices to cater for the learning and social needs of learners. Using an adapted Ghana Inclusive Education Monitoring Tool (IEMT), which is based on the Index for Inclusion, we collected data from 74 headteachers of primary schools. Data analysis involved percentages and…

This research was a quantitative case study on the possible relationship between school climate, student behavior, student achievement, and classroom facility factors in an urban Midwest high school. Specific variables included lighting, wall color, classroom temperature, school climate, student behavior, and student academic achievement. The…

A significant amount of research has been devoted to class size, in relation to student achievement. Success in the classroom is not only about increases in attainment. Fulfilment, and well-being, for teachers and students alike, is a more complete evaluation of improved achievement. The cost of reducing class sizes seems to be prohibitive, so…

The purpose of this study was to develop and validate study e-content in teaching and learning of automobile lighting system in technical colleges in Niger State, Nigeria. The study adopted Research and Development (R&D) design. The researchers modified the 10 steps of R&D model to 5 steps cycle which fits the present study. The five…

The construction and use of a low-cost continuous-flow instrument for measuring the kinetics of fast reaction which include the use of an light emitting diode light source, a photodiode-on-a-chip detector, and a position sensor is demonstrated. The instrument is suitable for the physical chemistry laboratory and could be used to study the kinetics…
