  • This chapter aims to clarify the concept of population balance model or population balance equation, terms that are used almost interchangeably in this book. This is followed by a short narrative of the strengths and weaknesses of these models. 1.1 What Are Population Balance Models? Population balance is not a well-defined concept in science and engineering, but means slightly different things to different people.

  • The NCRP has long recognized the need for a clear assessment of the magnitude of doses from various sources of radiation to which the population of the U.S. is exposed. In anticipation of the need to gather data for input into this process, five assessment committees, each addressing a different source category, were established. NCRP reports assessing exposures from natural background, consumer products, nuclear power generation, and diagnostic medical radiation have been published (NCRP, 1987a,b,c,d, NCRP, 1989)....

  • They find that the elasticity of CO2 emissions and energy are close to unity (i.e., a 1% increase in population leads to an approximately 1% increase in CO2 emissions). They do not estimate how these elasticities may vary with population levels. All of these results are based on cross-sectional data for 1 year only. Finally, Shi (2003), again in the context of the IPAT model, uses a panel of cross-sectional and time series data. Shi finds population elas- ticities for CO2 of between 1.41 and 1.

  • The present text introduces the use of population balances in the context of batch wet granulation and coating systems and it reviews the latest achievements and proposals in the scientific literature in this field. The nature and framework of population balance theory are highlighted and one-dimensional population balances are introduced from scratch. This may seems tedious at first but the derivation of even the simplest population balances is nevertheless not an easy task, and it is in fact difficult to find complete derivations elsewhere in literature.

  • In this short book, I try to outline the history of the European economy—which is somewhat different from an economic history of Eu-rope. By “European economy,” I mean a world economy in the sense of Fernand Braudel and Immanuel Wallerstein, one that is of course located in Europe and has some common aspects and some common institutions; one that is somewhat integrated, as its different parts are linked by trade and other relations more intensively than they are linked with other sys-tems; and one that achieves some kind of organic unity (despite diversity, which is typical of Europe)...

  • Of the many books that have been written about weed management, most have focused on the use of herbicides. This volume is different. Instead of providing information about chemical weed control technologies, the emphasis here is on weed management procedures that rely on manipulations of ecological conditions and relationships. By focusing on ecologically based methods of management, we have been able to provide in-depth treatment of subjects that most weed science books treat only briefly.

  • Most Cambodian elders have both living sons and daughters. Reflecting the higher mortality of males, including losses due to political violence associated with the Khmer Rouge period and its aftermath, the average number of surviving daughters modestly exceeds that of surviving sons. Some differences in the number of living children are evident according to sex, location and age of elders. Elderly men average larger numbers of surviving children than elderly women, reflecting the fact that men are far more likely to remarry than women in cases of marital dissolution.

  • The elderly population is seen differently in developing and developed countries. In the former, the age limit for a person to be considered old is 60 years; in the latter, this age limit is 65 years. This differentiation emerged during the First United Nations World Summit on Population Aging, through Resolution number 39/125(1). The need to establish chronological parameters for old age becomes more relevant as social and health actions are scheduled.

  • Third, we find that after accounting for luck, the percentage of funds with negative alphas in the population is approximately equal to 20% across all categories, while the proportion of funds with positive performance is much lower (it amounts to 1.9% of all funds in the population). It implies that the performance of the industry as a whole is not so bad because about 80% of the funds generate a performance sufficiently high to cover their expenses. The negative average performance documented in past studies is not due to the majority of funds but is caused by 20% of the funds....

  • Most observers of the economy now accept that a major shift occurred during the 1970s. The rapid productivity growth of the postwar years came to an end—for reasons that are still being debated among economists and historians. Wage growth lagged, and the economy suffered multiple shocks from energy prices and rapid inflation. The surge of births in the postwar baby boom meant that the labor force grew rapidly, while women were entering the labor force in numbers unprecedented in peacetime.

  • As life expectancy continues to rise, one of the greatest challenges of public health is to improve the quality of later years of life. The aim of this present study was to analyze the quality of life profile of the elderly across different demographic and socioeconomic factors. A cross-sectional study was carried out in two stages, involving 1,958 individuals aged 60 years or more. Health related quality of life (HRQOL) was assessed using the SF-36 questionnaire.

  • THE GROWING SIZE OF CANADA’S ELDERLY POPULATION and its use of health care services has generated much discussion in policy circles and the popular press. With data from the National Population Health Survey, undertaken in 1994–95, the authors examine the health status of Canada’s elderly population using 3 sets of measures: level of activity limitations, prevalence of chronic illnesses and self-assessment of overall health. They also analyse the utilization of physician and institutional services.

  • This book is about the distribution and abundance of different types of organism, and about the physical, chemical but especially the biological features and interactions that determine these distributions and abundances. Unlike some other sciences, the subject matter of ecology is apparent to everybody: most people have observed and pondered nature, and in this sense most people are ecologists of sorts. But ecology is not an easy science.
