Newton's Second Law
This lesson introduces students to Sir Isaac Newton's Second Law of Motion. Topics include the two ways to study the dynamics of a system in which there is motion and a brief description of Newton's work in studying and measuring the motion of objects.
GENIA Toolkit for Promoting Gender Equality in Education
The GENIA Toolkit is a collection of resources for use by gender focal points and education planners and implementers to promote gender equality and mainstream gender in the education system. These resources to help education planners incorporate gender equality into their work include Classroom Observation Tools and a Gender Lens for Community Learning Centers (CLC).
Video lecture from a series on Internet Applications delivered by Graham Mansfield. Running time approximately 37 minutes.
From 1991 until 1993 the Biosphere system supported people, plants, and animals. Experiments offered the opportunity for tracking in great detail the interactions among land and water ecosystems and the atmosphere. SimBio2 offers several scenarios in which students can generate simulation graphs using actual data from the Biosphere 2 experiment. Studentscan explore some of the problems that affected Biosphere 2 such as higher levels of carbon dioxide than expected and the resulting decrease oxy
Environmental Decision Making
Using the Extend 'connect-the-components' visual programming, students can model and simulate ecosystems including social and economic forces as well as study parameter variations to develop an understanding of ecosystem function and productivity. By making 'what if...' changes in the model, the effects of various proposed decisions about the environment can then be shown. EDM includes three ecological systems: Ponds, Grasslands, and Logging. Students can predict results of changes in the mode
Modeling Architectural Design Objectives in Physically Based Space Planning
Physically based space planning is a means for automating the conceptual design process by applying the physics of motion to space plan elements. This methodology provides for a responsive design process, which allows a designer to easily make decisions whose consequences immediately propagate throughout the design. It combines the speed of automated design methods with the flexibility of manual design methods, while adding a highly interactive quality and a sense of collaboration with the desig
An Integrated 3D Geodatabase for Palladio's Work
The paper presents a novel digital 3D GIS web-based system entirely founded on Google Earth, built to offer a deep insight into Palladio's opera for restitution of its architectural surveys, reconstruction for historical reasons, analysis for structural and other options, and assembly and presentation of all certified Palladian documentation.The development of the application follows the philosophy of visual computing and it is based on an architectural knowledge representation.The information s
Visualisation of construction information: A process view
This paper addresses the issue of information visualisation within the context of business process integration. Visual technologies offer appropriate information interfaces that facilitate the integration of mainstream construction applications. This paper assesses the needs of visualisation by the construction sector. It then describes recent developments in the areas of 4/5 dimensional modelling. Th
NASA CONNECT Virtual Earth: Using Concept Maps to Solve Problems
In NASA CONNECT Virtual Earth, students will be introduced to Earth system science. They will learn what a system is and how to apply the concept of systems to learn more about how the Earth functions. Students will understand the only way to really comprehend the workings of our planet is to look at the Earth as a whole system. They will also focus on Earth science applications of national priority to expand and accelerate the use of knowledge, science, and technologies resulting from the Earth
Re-Evaluation and Recommendations for Redesign of the World Trade Center : Final Report
After the collapse of the World Trade Center, Towers 1 and 2, several questions were raised about the fire protection, egress and emergency evacuation systems. Full engineering services were provided to analyze the design of these systems to investigate what improvements can be made to keep the buildings standing longer, which could have saved more lives. Towers 1 and 2 each has a building footprint of an acre, stood 110 stories tall, housed 50,000 employees and an additional 26,000 visitors da
Gender, sexual orientation and victim blame regarding male victims of sexual assault
Although research has found that between 5% to 20% of adult men in non-institutionalized and non-military populations have been the victimes of a sexual assault, these victims are largely ignored by society and mental health professionals. Factos that may account for this lack of attention may be due to the small number of victims (as compared to female victims) and rape myths that promote the denial that male rape can occur. The psychological literature also reflects this neglect as the majorit
Study of Non-Newtonian viscosity and yield stress of blood in a scanning capillary-tube rheometer (A Abstract: The study of hemorheology has been of great interest in the fields of biomedical engineering and medical researches for many years. Although a number of researchers have investigated correlations between whole blood viscosity and arterial diseases, stroke, hypertension, diabetes, smoking, aging, and gender, the medi

Synthesis and characterization of the properties of Ti3SiC2/SiC and Ti3SiC2/TiC composites
In 1996, the ternary compound titanium silicon carbide (Ti3SiC2) was for the first timesynthesized as a single-phase, fully dense compound. Its characterization revealed aunique combination of properties. For its high fracture toughness, low hardness toelastic modulus ratio and excellent damage tolerance, it was dubbed a soft ceramic. Italso displayed good thermal shock and oxidation resistance. In this work, thereinforcement of this material with silicon carbide and titanium carbide particles w
Type 1 diabetic model (A)
Diabetes mellitus is a chronic metabolic disease characterized by the uncoupling of bloodglucose levels and insulin secretion, causing abnormal glycemic excursions. Type 1diabetes is characterized by a complete insulin deficiency. Treatment consists ofattempting to match exogenous insulin delivery to the metabolic needs of the patientduring meals, exercise, and sleep. The objective is to minimize the frequency and severityof glycemic excursions and, more importantly, avoid hypoglycemic episodes.
The Story of Race in Charlotte Schools
In the 1970s, the public school system of Charlotte-Mecklenburg County in North Carolina was ordered by the federal courts to desegregate. The district then faced busing, lawsuits, protests, and riots during its struggle with the issue of racial quotas. The district is currently coping with the controversial plan to end busing for racial balance and return to a geographically-based student assignment plan. Listen to members of the Charlotte-Mecklenburg community candidly discuss race, desegreg
