This website provides a resource for the heritability of all human traits that have been investigated with the classical twin design. The traits have been classified into 28 broad trait domains, as well as according to the standard classification schemes of the International Classification of Functioning, Disability and Health (ICF) or the International Classification of Diseases and Related Health Problems (ICD-10). Currently the database includes information from 2748 papers, published between 1958 and 2012, reporting on 17804 traits on a total of 14,558,903 twin pairs. Have Fun!

Mada Assistive Technology Portal is the first digital platform specialized in assistive technology in Arabic. The portal provides a wide range of information, resources and assistive technology services to enable and support the independence of persons with disabilities through accessible information and communication technology ICT.

This portal provides a repository containing policies, laws and regulations related to ICT accessibility as a reference for legislators and policy makers, locally, regionally, and internationally. The purpose of this portal is to achieve inclusion by advocating for ICT accessibility policy adoption and development, in order to actively promote an inclusive ecosystem for people with disabilities in line with international best practices and within the framework of the United Nations Convention on the Rights of Persons with Disabilities (UNCRPD).

The purpose of Mada innovation program is to encourage innovators to bring relevant innovative Arabic assistive technologies and accessibility products and services for Persons with disabilities and the elderly.

This exercise is centered around a suite of rocks from the Sierra Nevada batholith. The activities are designed to give petrology students a capstone experience for the igneous portion of the upper-level Petrology course. Students are given thin sections with hand samples, a map and a table of geochemical analyses (in Excel format) and asked to record hand-sample and thin section observations with the idea that these will be used to understand processes that were active during batholith generation. By the time they encounter this lab, the students have spent at least 7 lab periods looking at a variety of igneous rocks and their textures. Because students are given geochemical analyses, they are also expected to experiment with the use of graphs (e.g., Harker and spider diagrams) to better understand tables of geochemical analyses. The students use observations about rocks and geochemistry to build a coherent story around these rocks; the final product is a short paper in which they use petrographic observations and geochemical diagrams to back up their interpretations.

This article, part of Biodiversity Counts, provides insight into what it takes to maintain an arthropod collection. The article contains advice to students for setting up and maintaining a small-scale collection, including what tools are needed, safe alternatives to chemicals for killing and preserving specimens and some of the techniques the museum uses to protect specimens that students may want to adopt.

This problem set introduces some of the more advanced uses of Excel to not only calculate how the chemistry of a magma changes with crystallization but also to see how the liquidus assemblage can drastically change the evolution of the remaining magma. Once they have their calculations complete, students plot the results and answer questions on the geochemical trends observed through the crystallization sequence. This problem set reinforces quantitative problem solving skills using a spreadsheet and has the students think about mineralogical controls on magma evolution.

This exercise is modified from one that Clark Johnson assigned at University of Wisconsin. I find this exercise to be more instructive for some of the tricks and tools in Excel, but there are some interesting questions that can derive from it. This assignment is often the first time the light goes on that you can end up with different composition magmas depending on what minerals are crystallizing, and that depends on the pressure of crystallization. There are many more questions that could be asked, such as where does this model fall short? What could be added or considered to make this a more realistic simulation of fractionation (more trace elements or REE).

Manual de como aplicar a matriz de indicadores de educação ambiental proposta por Vieira (2021) na educação formal, especificamente da educação infantil municipal de São José dos Pinhais PR, a partir de questões problemas relacionadas a educação ambiental na educação infantil através das dimensões gestão, currículo, espaço físico e comunidade, de forma democrática com a participação da comidade escolar.

The primary objective of this U.S. Geological Survey Open-file Report is to improve seismic-hazard assessments in regions of Wyoming with low to moderate levels of historic seismicity. A map and pamphlet are available for download in PDF format. The map shows faults and folds with evidence of Quaternary movement including data on timing of the most recent movement, sense of movement, slip rate, and continuity of surface expression.

Check out maps displaying data on monthly and annual employment and unemployment across the United States.

Students explore paleoclimate of the Quaternary Period by working with marine oxygen-isotope data from Ocean Drilling Program (ODP) core 677.

Clinical evidence has shown that physical exercise during pregnancy may alter brain devel- opment and improve cognitive function of offspring. However, the mechanisms through which maternal exercise might promote such effects are not well understood. The present study examined levels of brain-derived neurotrophic factor (BDNF) and absolute cell num- bers in the hippocampal formation and cerebral cortex of rat pups born from mothers exer- cised during pregnancy. Additionally, we evaluated the cognitive abilities of adult offspring in different behavioral paradigms (exploratory activity and habituation in open field tests, spatial memory in a water maze test, and aversive memory in a step-down inhibitory avoid- ance task). Results showed that maternal exercise during pregnancy increased BDNF lev- els and absolute numbers of neuronal and non-neuronal cells in the hippocampal formation of offspring. No differences in BDNF levels or cell numbers were detected in the cerebral cortex. It was also observed that offspring from exercised mothers exhibited better cognitive performance in nonassociative (habituation) and associative (spatial learning) mnemonic tasks than did offspring from sedentary mothers. Our findings indicate that maternal exer- cise during pregnancy enhances offspring cognitive function (habituation behavior and spa- tial learning) and increases BDNF levels and cell numbers in the hippocampal formation of offspring.

How big and how old is the universe? This culminating telescope investigation for high school students has them first taking images of galaxies near and far; then measuring and calculating their distances; then predicting how they might expect galaxies to be moving based on various models of gravity; and then comparing their results with the galaxy velocity measurements in a NASA database. From this data, students explore the concept of an expanding universe and can actually determine an estimate for the age of our universe. This activity is part of a DVD that is a professional development resource for educators. Many new astronomy learners, students and adults alike, are unfamiliar with the universe beyond the solar system. Instructions for obtaining the DVD and registering for the professional development workshop are contained on the website.

Students learn to determine the velocity of moving objects by doing simple analysis of video clips.

In this activity, we will explore how the dosage and frequency of a medicine taken affect the amount of medicine present in the blood.

Meiosis is the process by which gametes (eggs and sperm) are made. Gametes have only one set of chromosomes. Therefore, meiosis involves a reduction in the amount of genetic material. Each gamete has only half the chromosomes of the original germ cell. Explore meiosis with a computer model of dragons. Run meiosis, inspect the chromosomes, then choose gametes to fertilize. Predict the results of the dragon offspring and try to make a dragon without legs. Learn why all siblings do not look alike.
