We study the properties of star-forming galaxies at redshift z 2, an era in which a substantial fraction of the stellar mass in the universe formed. Using 114 near-IR spectra of the H-alpha and [N II] emission lines and model spectral energy distributions fit to rest-frame UV through IR photometry, we examine the galaxies' star formation properties, dynamical masses and velocity dispersions, spatially resolved kinematics, outflow properties, and metallicities as a function of stellar mass and age. While the stellar masses of the galaxies in our sample vary by a factor of 500, dynamical masses from H-alpha velocity dispersions and indirect estimates of gas masses imply that the variation of stellar mass is due as much to the evolution of the stellar population and the conversion of gas into stars as to intrinsic differences in the total masses of the galaxies. About 10% of the galaxies are apparently young starbursts with high gas fractions, caught just as they have begun to convert large amounts of gas into stars. Using the [N II]/H-alpha ratio of composite spectra to estimate the average oxygen abundance, we find a monotonic increase in metallicity with stellar mass. From the estimated gas fractions, we conclude that the observed mass-metallicity relation is primarily driven by the increase in metallicity as gas is converted to stars. The picture that emerges is of galaxies with a broad range in stellar population properties, from young galaxies with ages of a few tens of Myr, stellar masses M 10 DEGREES9 Msun, and metallicities Z 1/3 Zsun, to massive objects with M* 10 DEGREES11 Msun, Z Zsun, and ages as old as the universe allows. All, however, are rapidly star-forming, power galactic-scale outflows, and have masses in gas and stars of at least 10 DEGREES10 Msun, in keeping with their likely role as the progenitors of elliptical galaxies

This book examines farm machinery in the context of its history, corporations, outside market forces, regulations, and challenges and opportunities. The farm machinery industry is a complex sector of the global manufacturing economy that encompasses many companies, including those who that produce tractors, combines, planting equipment, tillage equipment, and irrigation systems. While the global industry is dominated by three full-line manufacturers (Deere and Company, Case New Holland, and the Allis-Gleaner Corporation), there are thousands of other companies, including many short-line manufacturers, that also dictate the nature of the industry. In recent years, equipment built by competitors from Asia have become more common in the farmstead landscape, capturing some of the market share U.S. manufacturers once dominated. This book examines farm machinery in the context of its history, corporations, outside market forces, regulations, and challenges and opportunities. The farm machinery industry, while contributing a small percentage to gross world product, is vitally important to another key sector of the economy—agriculture. In advanced economies, where the percentage of the labor force engaged in agriculture has been on the decline since World War II, high horsepower tractors and efficient harvesting systems are necessary to cultivate more acres with fewer workers to feed an ever-growing world population. Threats to profits in agriculture, such as natural disasters, climate change, and trade wars, increasingly challenge the profits and the viability of the farm machinery industry.

You have cancer." These are words people dread hearing. But when worse comes to worst, push comes to shove, something wonderful happens. More people come together for support and encouragement. More people participate in "Race for the Cure" events, and more people discover an inner strength within themselves that they never knew they had before. On the Wings of Pink Angels offers a gentle hand through this difficult time, sharing stories that inspire hope, strength, gratitude and courage during a time when someone must fight for his or her life against breast cancer.
This completely updated fifth edition of Bacterial Fish Pathogens is a comprehensive discussion of the biological aspects of the bacteria which cause disease in farmed and wild fish. Since the 4th edition was published in 2007, there has been an upturn in the application of molecular approaches to taxonomy, diagnosis and vaccine development. New pathogens, e.g. Aeromonas schubertii, have been described. Also, there has been the emergence of diseases caused by bacteria which have not been cultured, and which have been equated with new taxa, i.e. ‘Candidatus’. Consideration is given to all the bacterial fish pathogens, including primary pathogens and opportunists.
Punishing the Black Body examines the punitive and disciplinary technologies and ideologies embraced by ruling white elites in nineteenth-century Barbados and Jamaica. Among studies of the Caribbean on similar topics, this is the first to look at the meanings inscribed on the raced, gendered, and classed bodies on the receiving end of punishment. Dawn P. Harris uses theories of the body to detail the ways colonial states and their agents appropriated physicality to debase the black body, assert the inviolability of the white body, and demarcate the social boundaries between them. Noting marked demographic and geographic differences between Jamaica and Barbados, as well as any number of changes within the separate economic, political, and social trajectories of each island, Harris still finds that societal infractions by the subaltern populations of both islands brought on draconian forms of punishments aimed at maintaining the socio-racial hierarchy. Her investigation ranges across such topics as hair-cropping, the 1836 Emigration Act of Barbados and other punitive legislation, the state reprisals following the 1865 Morant Bay Rebellion in Jamaica, the use of the whip and the treadmill in jails and houses of correction, and methods of surveillance, policing, and limiting free movement. By focusing on meanings ascribed to the disciplined and punished body, Harris reminds us that the transitions between slavery, apprenticeship, and post-emancipation were not just a series of abstract phenomena signaling shifts in the prevailing order of things. For a large part of these islands' populations, these times of dramatic change were physically felt.
We have come to know that our ability to survive and grow as a nation to a very large degree depends upon our scientific progress. Moreover, it is not enough simply to keep 1 abreast of the rest of the world in scientific matters. We must maintain our leadership. President Harry Truman spoke those words in 1950, in the aftermath of World War II and in the midst of the Cold War. Indeed, the scientific and engineering leadership of the United States and its allies in the twentieth century played key roles in the successful outcomes of both World War II and the Cold War, sparing the world the twin horrors of fascism and totalitarian communism, and fueling the economic prosperity that followed. Today, as the United States and its allies once again find themselves at war, President Truman’s words ring as true as they did a half-century ago. The goal set out in the Truman Administration of maintaining leadership in science has remained the policy of the U. S. Government to this day: Dr. John Marburger, the Director of the Office of Science and Technology (OSTP) in the Executive Office of the President, made remarks to that effect during his 2 confirmation hearings in October 2001. The United States needs metrics for measuring its success in meeting this goal of maintaining leadership in science and technology. That is one of the reasons that the National Science Foundation (NSF) and many other agencies of the U. S.

The year is 1862. Prospectors swarm over the Sierra Nevada, hunting for gold, desperadoes roam the range, and the Indians are on the warpath. Dr. Henry Lockhart is so busy setting broken bones that he hasn't any time for women. Just as well. There's hardly a woman worth thinking about in the entire Nevada Territory. Then Erica James appears out of nowhere. Erica is different. She wears running shoes, totes around a contraption she calls a 'video camera,' and says she's from the future. From 1989, to be exact.
