A Review Of International Best Practice In E-Governmentsome Lessons For New Adopters, Deogratias Harorimana Sr

Dr Deogratias Harorimana

Efficient bureaucratic processes as essential to attract and retain investment, as well as promote SME growth. The e_Gov is one of many ways emerging economies have used to streamline public service delivery and create a freindly and conducive atmosphere for business -both MNC and SMEs. This presentation provide an overview of some of the World's most recent case examples on the successful design-plan-implementation of eGov to build a strong basis to attract investment and deliver seamless essential services to Citizens.

Surface Geometry And Heat Flux Effect On Thin Wire Nucleate Pool Boiling Of Subcooled Water In Microgravity, Troy Munro, Andrew Fassman

Presentations

The motivation of this nucleate boiling research is to understand the effects of surface geometry and heat flux as applied to a thin wire heater. This will further the understanding of the fundamental behaviors of boiling onset, steady state heat transfer, and bubble dynamics with respect to nucleate boiling with the goal of creating efficient thermal management systems for future space applications. Using three different thin platinum wire geometries and five different power levels, subcooled water was boiled over a period of approximately 30 seconds for 15 parabolic arcs to simulate microgravity. To represent the trends in bubbles behavior across …

Institute Overview, Morton Sternheim

Digital cameras and computers are widely available for students and teachers. However, they are mainly used for documentation: creating PPT presentations, handouts, posters, etc. STEM DIGITAL shows how digital image analysis can be applied to environmental (and other) research in STEM courses. Application to studies of air quality, water quality, arsenic contamination, climate change, diffusion, etc.

Water treatment engineers and public health officials need to pay careful attention to the presence of dissolved organic matter in water supplies selected for human consumption (i.e., raw drinking waters).

Measuring Albedo With Adi - An Intensity Application, Morton Sternheim

STEM Digital

Why are Polar Regions more affected by global warming than other parts of the globe? One reason (there are others) is that as sea ice melts and more open water appears, more energy is absorbed, and warming accelerates. This is a form of positive feedback and it makes the polar climate change faster than the climate in temperate areas. Increasing vegetation on land also has a similar positive feedback effect. This effect is a change in the albedo – the fraction of the incident sunlight that is reflected back to space.

Using Adi To Quantify A Color Change In Crayfish, Jennifer Welborn

Do Crayfish Change Color If Their Environment Changes? A Guided Inquiry Lab for 7th grade Life Science

Background: There is anecdotal evidence from bass fisherman that crayfish are able to change color depending on their surroundings. A (cursory) literature review of this phenomenon showed that no formal research has been done in this area. Students had an additional informal lesson about research funding (or lack thereof) because of this finding.

Students designed and conducted a controlled experiment to see the effect of changing environment color on crayfish color.

ADI was used to quantify a color change.

Human Variation In Skin Color And Race As A Social Construct, Jennifer Welborn

STEM Digital

This lesson is part of evolution unit which follows heredity and genetics

The lesson is interdisciplinary in nature in that I discuss the concept of race as a social construct and the idea that there are “black, white, red, yellow” skinned people is something that people developed. It is not based on biology. Race groupings are human-made groups.

Students first learn about mixing light and how to determine black and white from an ADI analysis. They learn that red and green = yellow, etc.

They then photograph each other’s forearms and analyze the images using ADI.

We then discuss skin …
