  • Sewage sludge as an uncalled for product of wastewater treatment poses the challenge to society of disposing of it, but at the same time gives us the opportunity of beneficial use by closing the cycle of nutrients: sludge derived from agricultural activity must return to soil if a sustainable and ecologically sound management of these materials is desirable (SEQUI et al. 2000). At present the major ways of disposing of sewage sludges are deposition, landfill and incineration, only part of the sludges are used in agriculture. ...

  • When choosing which typefaces to use for a web-based project, there are a number of limitations that are not a factor when designing for printed materials. With a print project, the designer may use any typeface he or she desires, as the typeface is sent to the printer with the rest of the document (layout, text, colors and images). However, when designing for the web, the designer is only able to use the typefaces he or she knows are available on all major computer operating systems, such as Microsoft Windows and the Apple Mac OSX. These fonts are referred to...

  • Forests ecosystems provide a multiplicity of goods and services of crucial ecological, social and economic importance for the sustainability of our society. Forest goods and services represent the benefits that human populations derive, directly or indirectly, from forest ecosystems functions (MEA 2005) and are therefore an inherently anthropogenic concept, since it is the presence of human beings as valuing agents that enables the translation of the basic ecological structures and processes of forests into value-laden entities. ...

  • In addition to visual art, the conference also covered a topic of special interest in visual neuroaesthetics: facial beauty. Other peo- ple’s faces constitute highly relevant stimuli for humans, and face perception is mediated by distributed neural regions (Ishai, 2007), including the extrastriate cortex, which is specially dedicated to processing individual identity, and the superior temporal sulcus, which processes facial movements involved in speech and direct- ing gaze.

  • This addresses the bandwidth problem, in a way: A web site owner will certainly service fewer RSS requests as end users start polling the central service instead. The operators of these central services will definitely have bandwidth issues of their own: they will now be at the center of all RSS traffic. There is a far more insidious danger inherent in this approach, however: a central point of control, failure, and censorship has now been established for all partici- pating users.

  • Height and weight of the subjects were measured using standard procedures. The weight was measured using SECA balance with minimum of cloths to the nearest of 100 gms and height was measured using an anthropometric rod to the minimum of 0.5 cm. Body mass index (BMI : weight in kg/height in meters2 ) was calculated from heights and weights. A value ≤ 18.5 is considered as a cut-off point for chronic energy deficiency (CED) or undernutrition (thinness), while BMI ≥ 25 is considered as overweight or obese. Prevalence of diseases in both groups separately was calculated.

  • We analyze a sample of 159 U.S. public companies that restated their earnings in the years 2000 or 2001 and an industry-size matched control sample of 159 nonrestating firms. We have assembled a unique, handcollected data set that contains detailed information on the corporate governance characteristics of these 318 firms. Our sample includes restatements by prominent firms such as Abbott Laboratories, Adelphia, Enron, Gateway, Kroger, Lucent, Rite-Aid, Tyco, and Xerox.

  • The industry approach to environmental issues has moved from ‘end-of-pipe’ solutions, towards a pollu- tion prevention strategy. This strategy requires an integrated, holistic view of activities. Tools have been developed to assist management, including cleaner production, life cycle assessment and industrial ecolo- gy. Each of these looks at the life cycle of the product or service, to identify where the major environmental issues or problems may arise and where the most cost- effective solutions can be developed.

  • The most spectacular changes in the recent decades have been a radical change in bleaching technology, that minimised the use of chlorine and greatly reduced or avoided altogether the emissions of dioxins (Reinstaller, 2005), and the increase in the use of re- cycled paper as an input in the paper production process. Although less spectacular and more gradually, the pulp and paper industry in Europe has also improved its performance in other environmental dimensions (Berkhout, 2005).

  • Several European cases highlight to varying degrees the roles of direct and indirect crossborder credit in the course of the global credit boom of the 2000s (Graph 1). Direct crossborder credit to non-banks in Ireland (dark shaded area), for example, grew at roughly 40% year on year in the three years prior to the crisis (centre panel), 10 percentage points above the rate for domestic bank credit. Moreover, banks in Ireland drew on indirect cross-border credit (left-hand panel, dashed brown line) to support their domestic lending.

  • The work programme also covers the complementary policy objective of addressing specific global health issues. Greater focus will be placed on antimicrobial resistance and continuing to address emerging epidemics. In antimicrobial resistance the aim will be to further focus on understanding of the evolution and the transfer of antibiotic resistance as well as antimicrobial drug resistance in Gram negative infections, the development of tools to control microbial biofilms and the development of multi-analyte diagnostics.

  • The biological changes underlying the transition process from gingival health to early inflammatory changes involve local increase in vascular permeability, edema and the recruitment and activation of polymorphonuclear neutrophils (PMN) (Delima and Van Dyke 2003). Acquired immune response becomes involved once antigen-presenting cells interact with immunocompetent cells, such as T and B lymphocytes, leading to the expansion of antibody-secreting plasma cells and the development of the chronic lesion (Gemmell and Seymour 2004).

  • On the other hand, salinity affects 7-9 % of the world’s land area (Szabolcs, 1994), and the area is increasing (Ghassemi et al., 1995). Nowadays, one of the major technological goals of the energy production is the replacement of the fossil-based fuel for biofuel, mainly due to environmental issues. Bearing that in mind, it is mandatory to investigate the effect of water deficit and salinity stress in plant species with high potential for application in large scale production of nonfossil based fuels....
