"Must a Fellow Wait to Die?": Workers Write to Frances Perkins
Silicosis, a deadly lung disease caused when workers inhale fine particles of silica dust—a mineral found in sand, quartz, and granite—became a national cause célèbre during the Great Depression when it was recognized as a significant disease among lead, zinc, and silver miners, sandblasters, and foundry and tunnel workers. In 1938 the federal government declared silicosis America's number one industrial health problem and Secretary of Labor Frances Perkins convened a National Silicosis Co
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
Module 5: Selecting Payment Methods
Select appropriate methods, terms, and currency of payment to agents, sales representatives, distributors, suppliers, and international joint ventures. MSU Global has teamed with experts in the international finance field to create resources to help increase international skills in the business community. These materials address the need of the international trade practitioner for knowledge and information that is specific to trade finance by providing a means for educators and business practit

Travel With Care Safety Tip 4
The City of Auburn and Auburn University have partnered to bring Travel With Care Auburn, a public safety campaign aimed at audiences using all forms of transportation: motorists, pedestrians, cyclists, and transit riders. Throughout the week of April 4-8, members of the Auburn Public Safety - Police Division will be patrolling city streets and the Auburn University campus to bring awareness to traffic issues, while student volunteers will pass out informational brochures.
Oceans, climate and weather
What is the difference between weather and climate? What do the oceans have to do with them? Weather is the day-to-day state of the atmosphere and its short-term (minutes to weeks) variation. This publication is all about developing your students’ understandings of earth’s oceans and the major effect they have on climate. Understanding and interpreting local weather data and understanding the relationship between weather and climate are important first steps to understanding larger-scale gl

Guide for Developing “Quick” and Extensive Profiles of the Primary Internship Site
Interns work directly with on-site supervisors (mentors), home-school principals, or other principals, supervisors, or agency administrators on specified objectives for the number of clock hours designated in a signed agreement. The mentor or campus supervisor approves all experiences used for the completion of objectives. At least one reading is selected to facilitate the achievement of each objective in the internship. Reflections on the experiences, the readings, and the relationship between
Application of the Hardy-Weinberg model to a mixed population of Bar and wild-type Drosophila
Unlike most population genetics labs, which involve simulations with beans or beads, this lab provides an opportunity to study a population of living organisms. Using Bar and wild-type Drosophila, students compare allele and genotype frequencies to Hardy-Weinberg expectations. Because the Bar mutation in Drosophila is sex-linked and incompletely dominant, students can determine the exact genotype of a fly from its phenotype. These data are evaluated to determine which (if any) of the five Hardy-
Feed the Birds
This OLogy activity introduces kids to the concept of biodiversity by helping them discover the diversity of their local bird population. To begin, students create a simple bird feeder from a milk/juice carton or a plastic soda bottle. They then fill the feeder with black-oil sunflower seeds, popular with a range of birds. In addition, they are given a list of additional foods to experiment with, such as millet, raisins, and breakfast cereal. Students track the birds that visit their feeder in f
Newton Gets Me Moving
In this lesson, students will explore motion, rockets and rocket motion while assisting Spacewoman Tess, Spaceman Rohan and Maya in their explorations. They will first learn some basic facts about vehicles, rockets and why we use them. Then, the students will discover that the motion of all objects including the flight of a rocket and movement of a canoe is governed by Newton's three laws of motion.
Sticks and Stones Will Break That Bone!
Students learn about the strength of bones and methods of helping to mend fractured bones. During a class demonstration, a chicken bone is broken by applying a load until it reaches a point of failure (fracture). Then, working as biomedical engineers, students teams design their own splint or cast to help repair a fractured bone, learning about the strength of materials used.
Engineering for the Three Little Pigs
The purpose of this activity is to demonstrate the importance of rocks, soils and minerals in engineering and how using the right material for the right job is important. The students build three different sand castles and test them for strength and resistance to weathering. Then, they discuss how the buildings are different and what engineers need to think about when using rocks, soils and minerals for construction.
Students will gain knowledge of whales: the kinds of whales, the characteristics of whales, and the habitats of whales. Math skills will be incorporated into the teaching facts about whales.
Cervical Myelopathy - Station and Gait Exam - Station Sub-exam - Patient 13
This 46-year-old African American male presented with progressive weakness of the lower extremities for three months. He had increasing difficulty with walking and balance and now is unable to walk without assistance. He also complained of numbness and "pins and needles" sensation in the upper extremities with clumsiness and decreased dexterity in his right hand. He did not have neck or radicular pain and had no bowel or bladder problems or sexual dysfunction, but did have some urinary urgency.
Parkinson Disease - Reflexes Exam - Muscle Stretch Sub-exam - Patient 4
This 76-year-old man developed tremor of his right arm and leg 15 years ago. It has increased in severity over the years. A shaking right hand affects his writing, dressing and drinking. Occasional drooling, difficulty rolling over in bed and a soft voice at times are also issues. The tremor has affected his writing and he has mild difficulty with buttons and zippers. He spills when he uses his right hand to drink. He has occasional drooling and slight difficulty rolling over in bed. His voice
