  • As indicated in Chapter 1 of this book, land application of sewage sludge and biosolids has been practiced for centuries. Over the past 40 years, I have been involved in various aspects of organic matter and soils. Since 1972, I have researched, studied, and published on various aspects of biosolids management, concentrating on composting and the public health aspects of land application. I have been an active member on the Water Environment Federation Residuals Committee and The U.S. Composting Council Board of Directors.

  • The living organism which will be deeply affected are shredders, which feed on coarse sedimentary detritus, and collector-gatherers, which feed on fine sedimentary detritus, were the macroinvertebrate functional feeding groups are most adversely affected. Furthermore, during the industrial process, high amount of hydrofluoric acid (HF) are used to separate different sandy materials which are subsequently used for manufacturing glass at industrial plants. Therefore, high concentration of fluoride ion and suspended inorganic matter discharged by the industrial into the study site....

  • Eleven million tonnes of waste are produced yearly by the European pulp and paper industry, of which 70% originates from the production of deinked recycled paper. Wastes are very diverse in composition and consist of rejects, different types of sludges and ashes in mills having on-site incineration treatment. The production of pulp and paper from virgin pulp generates less waste but the waste has similar properties to waste from the production of deinked pulp, although with less inorganics [...].

  • The team in Scrum is typically five to ten people, although teams as large as 15 and as small as 3 report benefits, and for a software project the team might include analysts, developers, interface designers, and testers. The team builds the product, but they also provide input and ideas to the Product Owner about how to make the product as good as it can be. While team members can split their time between Scrum projects and other projects, it’s much more productive to have team members fully dedicated. Team members can also change from one Sprint to the next,...

  • The Environment Agency is the lead organisation for providing flood and coastal risk management and warnings of flooding from main rivers and on the coast. We are responsible for the strategic overview for all sources of flooding. This means we will advise and bring together the planning and management of flood risk from rivers, the sea, groundwater, reservoirs and surface water. Many different public and private bodies are involved in managing flood and coastal erosion risk, each accountable for different aspects of risk management.

  • The presence of chlorine in alternative fuels (e.g., sewage sludge, municipal solid waste or incineration ash, chlorinated biomass,) has both direct and indirect implications on cement kiln emissions and performance. Methods have been developed to properly manage chlorine and its potential implications – but it is important that these implications be recognized and managed. Trace levels of chlorine in feed materials can lead to the formation of acidic gases such as hydrogen chloride (HCl) and hydrogen fluoride (HF) (WBCSD 2002).

  • A better understanding of the influence of tobacco smoke on the host response to periodontal infection has been the major concern in numerous studies whereas, limited research has been published aiming to identify the influence of tobacco smoke on the dental biofilm. Tobacco smoke has been shown to cause shifts in the microbial species that comprise dental plaque (Haffajee & Socransky 2001, Kamma et al. 1999, Shiloah et al. 2000, Umeda et al. 1998, van Winkelhoff et al. 2001, Zambon et al. 1996).

  • With this approach the geometry and structure aspects of the bridge must be known (such as the depth of the girder, the connection between the beams and deck, steel detailing, steel strength, etc.). With this information and assumptions and boundary conditions for load distribution along with the characteristics, analysis of the beam line can then be carried out and the load factor assessment development (AASTHO, 1994).

  • But, establishing a lower-than-market interest rate by means of a usury ceiling will also bring about a decrease in the quantity of credit supplied. Given lenders costs, the amount of credit they will provide when the interest rate is held down is limited. Like any other business, if a lender does not recoup its costs and earn an adequate return on its resources, it will put those resources to work elsewhere.

  • Flow cytometry in our studies contributes to better understanding of prokaryotic roles in the Adriatic Sea as a separate ecosystem and as an important part of the Mediterranean Sea. Studies of prokaryotic community by flow cytometry in the eastern part of Adriatic Sea started in year 2003. The first studies were carried out for purposes of comparing two direct counting methods for bacterioplankton (Šantić et al., 2007). The accuracy of epifluorescence microscopy (EM) was assessed against direct counts made by flow cytometry (FCM).

  • Ever since the Industrial Revolution, industrial activities have been accompanied by a problem: industrial waste. The commensurate increase in industrialization, urbanization and population growth are leading to production of enormous quantities of industrial wastes that may cause degradation in environment and health hazards. On the other hand, the desire for a healthy environment increases, which leads to the need for better ways of waste minimization, pollution prevention and better use of resources in achieving the required industrial and environmental standards....

  • In summary, a long series of studies have investigated the relationship between income and pollution as defined by the Environmental Kutznets Curve. Papers by Grossman and Krueger (1991), Shafik and Bandyopadhyay (1992) and Selden and Song (1994) presented evidence that some pollutants have historically followed an inverted U-curve with respect to income. Although these and other empirical studies point to a correlation between income and pollution, the causal relation is not observed for all sets of data.

  • We know it takes some time to get used to this new way of life. But you’ll get over it. However, this is where the motivation for studying the program comes in to play. If you are not motivated enough to keep on with this new lifestyle for the next five or six years, chances are you’ll run out of steam way before the first year ends. A high motivation is an excellent substitute for sleep; lack of motivation won’t help at all no matter how many hours you sleep every day. This is why we stress again: Be careful...

  • Yet these commercial outcomes are the tip of the iceberg. What matters most, to those who live or work in a city, as much as its visitors, is its quality of life, of which culture is the essence. Cities offer not just a natural environment, but a built and cultural one. London’s air, rivers and green spaces are a backdrop; it falls to its building and activities to set the stage on which its life plays out. This is why the cultural quality of life of London’s citizens is an object of policy in its own right. London’s cultural environment also...
