Cement production may be classified by application into two primary groups: construction and energy services. The construction applications for cementing consume the lion’s share of cement manufactured world-wide, but the cement produced for energy services applications is an integral part of meeting the world’s energy needs and requires tighter quality control standards to meet that industry’s higher demands on control of the rheological properties of the fluid slurry state, the solid state, and especially the transition from the former state to the latter, or the setting process. Applications relating to the energy services industry are the primary focus of this work. Additionally, cement may also become central to efforts in nuclear waste management by locking radioactive material within the cementitious matrix, where rates of diffusion of waste out of the cement serve as the dominant concern. These modules explain the chemistry of Portland cement and its applications for the energy industry.

The thirteen photographs in this slideshow depict farm laborers, factory employees, and other Wisconsin workers from the 1890s to the 1970s. Looking at these images, we wonder: what was on the minds of these now-anonymous men and women as they posed for the photographer? Were they proud of their work, their uniforms, their employers? Were they pleased to have a break or anxious to get back to the task at hand?

This professionalism guide by The American Board of Pediatrics helps students learn about positive behaviors in a healthcare setting. The website provides a detailed description of positive work behaviors and professionalism in a healthcare setting. As students review this section, they should create a list. It also provides some examples of negative work behaviors in a healthcare setting so students can distinguish between positive and negative behaviors. The website also provides 7 vignettes to use as an interactive activity. Students can be split into small groups and given one vignette, and then they can discuss what a positive, professional response would look like to each scenario. The goal of this activity is to prepare students to act professionally and positively in a healthcare job.

A California Guide to Align Civic Education and the Common Core State Standards for English Language Arts and Literacy in History/Social Studies, Science and Technical Subjects. This resource guide provides educators with practices to equip all students with reading, writing, listening and speaking skills and the knowledge, skills and dispositions to become responsible engaged citizens of the 21st century in a coherent, integrated manner that will be meaningful and relevant. The practices in the guide provide civic education approaches to meet the Common Core State Standards for English Language Arts. The lesson activities in each of the grade spans follow a natural progression that builds students’ historical knowledge of the foundations of democracy, an understanding of how America’s constitutional principles are reinterpreted over time, and the skills and dispositions needed for effective citizenship. Applied knowledge of history, government and civics is necessary for developing civic competency. Therefore, each series of lessons calls for students to actively participate in activities that strengthen reading, writing, speaking and listening skills in the context of civic dialogue, debate, persuasion and action.

Edward Gould Buffum (1820-1867) went to California in 1846 as a soldier in a New York regiment during the Mexican War. There, Buffum and his regiment helped wrest California from Mexico. After his discharge from the army, Buffum remained to pan gold in the area around John Sutter's sawmills where it had just been discovered. A journalist by profession, Buffum recorded his experiences in a book, Six Months in the Gold Mines, from which this excerpt comes. He commented with wonder that men in the California gold mines earned one hundred dollars per day on average. To understand what a fortune this was, consider that women working as domestic servants in northeastern cities at this time earned between four and seven dollars per month.

By Around 1903, employers began to mount organized campaigns to break the power of labor unions, particularly in the metal trades. Employers had a broad array of weapons in their arsenal, including blacklists, strikebreakers, and court injunctions against strikers' use of boycotts and sympathy strikes. Although early twentieth-century employers had reliable allies in state police forces and tightly controlled local police, they continued to hire their own private police--detective agencies that used secret operatives to disrupt unions and supplied thugs to protect strikebreakers during strikes. This 1917 ad for the Cleveland-based Joy Detective Agency appeared in American Industries, the official publication of the National Association of Manufacturers.

President Lyndon Johnson formed an 11-member National Advisory Commission on Civil Disorders in July 1967 to explain the riots that plagued cities each summer since 1964 and to provide recommendations for the future. The Commission's 1968 report, informally known as the Kerner Report, concluded that the nation was "moving toward two societies, one black, one white--separate and unequal." Unless conditions were remedied, the Commission warned, the country faced a "system of 'apartheid'" in its major cities. The Kerner report delivered an indictment of "white society" for isolating and neglecting African Americans and urged legislation to promote racial integration and to enrich slums--primarily through the creation of jobs, job training programs, and decent housing. President Johnson, however, rejected the recommendations. In April 1968, one month after the release of the Kerner report, rioting broke out in more than 100 cities following the assassination of civil rights leader Martin Luther King, Jr. In the following excerpts from the Kerner Report summary, the Commission predicted a grim future for American cities unless the nation undertook concerted actions leading to "a true union--a single society and a single American identity." In 1998, 30 years after the issuance of the Report, former Senator and Commission member Fred R. Harris co-authored a study that found the racial divide had grown in the ensuing years with inner-city unemployment at crisis levels. Opposing voices argued that the Commission's prediction of separate societies had failed to materialize due to a marked increase in the number of African Americans living in suburbs.

In this course, you will be exposed to a number of different sub-fields within finance. You will learn how to determine which projects have the best potential payoff, to manage investments, and even to value stocks. In the end, you will discover that all finance boils down to one concept: return. In essence, finance asks: ŇIf I give you money today, how much money will I get back in the future?Ó Though the answer to this question will vary widely from case to case, by the time you finish this course, you will know how to find the answer.

The purpose of this course is to provide the student with a basic understanding of the principles of microeconomics. At its core, the study of economics deals with the choices and decisions that have to be made in order to manage scarce resources available to us. Microeconomics is the branch of economics that pertains to decisions made at the individual level, i.e. by individual consumers or individual firms, after evaluating resources, costs, and tradeoffs. "The economy" refers to the marketplace or system in which these choices interact with one another. In this course, the student will learn how and why these decisions are made and how they affect one another in the economy. Upon successful completion of this course, students will be able to: Think intuitively about economic problems; Identify how individual economic agents make rational choices given scarce resources and will know how to optimize the use of resources at hand; Understand some simplistic economic models related to Production, Trade, and the Circular Flow of Resources; Analyze and apply the mechanics of Demand and Supply for Individuals, Firms, and the Market; Apply the concept of Marginal Analysis in order to make optimal choices and identify whether the choices are 'efficient' or 'equitable'; Apply the concept of Elasticity as a measure of responsiveness to various variables; Identify the characteristic differences amongst various market structures, namely, Perfectly Competitive Markets, Non-Competitive Markets, and Imperfectly Competitive Markets and understand the differences in their operation; Analyze how the Demand and Supply technique works for the Resource Markets.

The principles of rock mechancis explains the fundamental concepts of continuum mechanics and rheology as applied in studies of rock deformation. A thorough understanding of rock behavior is essential for strategic planning in the petroleum and mining industry, in construction operation, and in locating subsurface repositories. The formation of geological structures or rock deformation patterns, studied by geodynamicists and tectonicians, is, also governed by the mechanical principles outlined in this textbook. The aim of the present book is obvious: to inspire a new generation of positively forward-thinking geoscientists and engineers, skillful in and favorable to the practical application of mechanics to rock structures.

At the close of the American Revolution the British ignored their Indian allies and ceded all British lands from the Atlantic coast to the Mississippi River to the new United States. Increasing numbers of settlers in the Ohio Valley often skirmished with the many woodland Indian peoples who stayed on their ancestral lands. President Washington sent the first of three armies into the region in 1790. When the first two expeditions failed, Washington turned to General Anthony Wayne. After his victory in the Battle of Fallen Timbers in 1795, Wayne staged an elaborate ceremony at Fort Greenville to recognize American sovereignty over the land and his paternalistic authority over the Indians. Little Turtle, a Miami leader integral to the first two Indian victories, balked at Wayne's terms and was the last Indian participant to agree to cede two thirds of northern Ohio and southeastern Indiana. In exchange, the Americans agreed to Indian occupancy of the remaining lands. But this agreement was not to last for long.

As U.S. soldiers returned from Europe in the aftermath of World War I, scarce housing and jobs heightened racial and class antagonisms across urban America. African-American soldiers, in particular, came home from the war expecting to enjoy the full rights of citizenship that they had fought to defend overseas. In the spring and summer of 1919, murderous race riots erupted in 22 American cities and towns. Chicago experienced the most severe of these riots. The most detailed and sober reporting of the causes of the 1919 Chicago race riot came retrospectively from the interracial Chicago Commission on Race Relations. The Commission published a seven hundred-page report in 1922, The Negro in Chicago. Charles Johnson--a Chicago Urban League official, the associate executive secretary of the integrated commission, and the principal author of its report--hoped that by thoroughly describing the sentiments and living conditions of African Americans and the similarities between European immigrants and recent black migrants to Chicago, the report would generate sympathy for the city's black community. Filled with photographs, charts, and maps, The Negro in Chicago carefully dissected Chicago's racial problems, including black and white antagonism over housing, jobs, and crime.
