  • The last decade has contributed significantly to the development of research on the biogeochemistry of tropical mangrove ecosystems. Also obvious during the last decade is the continued and dramatic destruction of natural tropical mangrove resources in Southeast Asia (Fig. 1.1). The naturally high productivity of tropi- cal mangroves has traditionally been exploited for a wide variety of purposes, both as sources of forestry or fisheries products and they have also been used for human settlement (Hatcher et al., 1989; Platong, 1998).

  • Organic carbon concentrations can be reduced by enhanced coagulation, granular activated carbon or membrane filtration, but this fact can also lead to increased in brominated THMs (Black et al, 1996.). A combination of coagulation, ozonation, and biofiltration can effectively reduce trihalomethane and haloacetic acid formation potential (Chaiket et al, 2002.). Natural organic matter (NOM), the main precursor of DBPs, can also be removed by media filters coated with iron oxide

  • Although the United States is the most powerful nation on earth, the one area in which this country does not excel is health. And the future is not bright. Almost a third of our young children are obese, and many do not exercise. No matter how much information becomes available about the dangers of a sedentary lifestyle and a diet heavily dependent on processed foods, we don't change our ways. Ideally, Americans should be able to translate financial well-being into habits that lead to longer and better lives, untroubled by expensive and chronic medical illnesses.

  • As early as the beginning of the 20th century Rudolf Diesel proposed vegetable oil as fuel for his engine.1 A short time later, before and during World War Two, vegetable oil was examined in “up-to-date” diesel engines. In 1940 first trials with vegetable oil methyl and ethyl esters were carried out in France and, at the same time, scientists in Belgium were using palm oil ethyl ester as a fuel for buses.2 In 1973, the oil crisis refocused attention on and interest for local energy sources.

  • Although data quantifying particulate emissions from construction and demolition work is scarce, some research carried out in USA gives an estimation for TSP of 2.5 tonnes/hectare/month in zones where large construction work is in progress. The quantity of particles emitted in each city from this source will depend on the type of construction in progress. These particles are mainly present in size fractions greater than 10µm. However, some fraction of the total amount is likely to be present as smaller particles. Also, some of this dust will be resuspended either by traffic or wind.

This is due to the limited direct health impacts associated with exposure to modest amounts of carbon monoxide. There has also been a gerneral decrease in the ambient concentrations of carbon monoxide measured in recent years as a result of improved vehicle technology.

  • Secondly, seeking out paid work should always be the choice of women themselves. Policies adopted by conservative government administrations such as workfare, which force social assistance recipients into the workforce, ìÖcreate a source of low-wage and free labour by providing subsidies to the private sector and forcing recipients to volunteer in exchange for assistanceî. 22 These polices are based on a distrust of those living in poverty, and do not empower, but malign people into working for pay.

  • A general overview of the literature focusing on the origins of losses, discussing the intertemporal solvency of central banks and modelling their balance sheets has been presented already in Cincibuch et al. (2008; 2009). Many useful general references can also be found in a recently published book edited by Milton and Sinclair (2011). In the present paper, we thus limit ourselves to reviewing specifically those papers that have explicitly discussed the link from central bank finances to policy pursuit, with an emphasis on empirical work.

  • A pilot study was conducted to assess the feasibility of composting of source separated organic matter of municipal solid waste (MSW) generated in low, middle and high income areas of Karachi city with a population over 14 million. Results of MSW analysis indicate the presence of high percentage of biodegradable organic matter (71-74%), acceptable moisture content (40-50%) and C/N ratio (38-40:1). On windrow composting, not only the volume of waste was reduced but also produced a crumbly earthy smelling soil-like, compost material.
