Al-Abid
The Al-Abid(Arabic: العابد) LV was an Iraqi three-stage "Satellite launch system", a civilian project that was commenced in 1988. The Iraqis intended to launch an Al-Ta'ir satellite with the help of such a launch vehicle. The Iraqis therefore pursued a LV with stages based on Scud missiles and the S-75 Dvina. However only the first stage could be tested on December 1989 and according to General Ra'ad the next stages could not be developed. General Ra'ad says that not even the drawings of the second and third stage vehicles are available and that no final report could be produced. UN inspectors and U.S intelligence did not offer many details regarding the Al-Abid launch vehicle as they were not interested in it.

Sediment Quality Triad (SQT)
In aquatic toxicology, the sediment quality triad (SQT) approach has been used as an assessment tool to evaluate the extent of sediment degradation resulting from contaminants released due to human activity present in aquatic environments (Chapman, 1990). This evaluation focuses on three main components: 1.) sediment chemistry, 2.) sediment toxicity tests using aquatic organisms, and 3.) the field effects on the benthic organisms (Chapman, 1990). Often used in risk assessment, the combination of three lines of evidence can lead to a comprehensive understanding of the possible effects to the aquatic community (Chapman, 1997). Although the SQT approach does not provide a cause-and-effect relationship linking concentrations of individual chemicals to adverse biological effects, it does provide an assessment of sediment quality commonly used to explain sediment characteristics quantitatively. The information provided by each portion of the SQT is unique and complementary, and the combination of these portions is necessary because no single characteristic provides comprehensive information regarding a specific site (Chapman, 1997)

Adaptation to Global Warming in Australia
According to non-governmental organizations such as Greenpeace and global scientific organisations such as the United Nations Intergovernmental Panel on Climate Change, the frequency and intensity of disasters brought about by greenhouse gas emissions and climate change will grow rapidly in the world. The risks are particularly severe in some regions of Australia , such as the Great Barrier Reef in Queensland, the Macquarie Marshes in New South Wales. The Department of Climate Change said in its Climate Change Impacts and Costs fact sheet: "...ecologically rich sites, such as the Great Barrier Reef, Queensland Wet Tropics, Kakadu Wetlands, Australian Alpine areas, south-western Australia and sub- Antarctic islands are all at risk, with significant loss of biodiversity projected to occur by 2020". It also said: "Very conservatively, 90 Australian animal species have so far been identified at risk from climate change, including mammals, insects, birds, reptiles, fish and amphibians from all parts of Australia." Australia is already the driest populated continent in the world. Climate change is recognised as one of the largest global crises. The issue has gained traction around the world as the world becomes increasingly urbanised. This is because urbanisation brings irreversible changes in our patterns of resource/waste production and consumption. Therefore, how to plan, manage and live in cities will be largely determined by the progress of the climate change phenomenon. According to projections by the Department of Climate Change in Australia, it is expected that national average temperatures would increase by 0.4 to 2.0 °C . Based on some predictions for 2070, data suggests that people who are not used to the hotter climate may experience as much as 45 days per year where they are unable to handle being outside in comparison to the current 4–6 days per year. Rainfall patterns and the degree of droughts and storms brought about by extreme weather conditions are likely to be affected. Research has suggested that nearly three-quarters of global energy consumption occur in cities, while emissions of greenhouse gases that cause global warming come from urban areas. Nearly a third of these emissions are caused by the burning of fossil fuels used in urban transportation. Another third is formed from the energy used to regulate building temperature and to run personal appliances. The final third is contributed by the industrial sector. The main emitters of greenhouse gases are the construction, real estate, agriculture and metallurgical industries, the transportation sector, the industrial uses of fossil fuels and the burning of biomass. Some examples of daily activities that contribute to the amount of greenhouse gases in the atmosphere include the use of carbon-based electricity in street lighting, driving motor vehicles, cooking, and the lighting, heating and cooling of housing. If the policies of Organisation for Economic Co-operation and Development (OECD) countries remain unchanged, specifically Australia and the United States, and also China and India, carbon dioxide emissions, which represents 72% of all greenhouse gas emissions, will increase by a third in the year 2020 instead of the 5% reduction as was approved in the Kyoto Protocol. With the current path of climate change, the world population is entering an era of growing urban vulnerability. The accelerated pace of urbanisation and the increasing percentage of the world's population living in cities has significantly increased the vulnerability of urban areas as anthropogenic hazards and agents for climate change.

Deacetylation
Acetylation (or in IUPAC nomenclature ethanoylation) describes a reaction that introduces an acetyl functional group into a chemical compound. Deacetylation is the removal of an acetyl group. Acetylation refers to the process of introducing an acetyl group (resulting in an acetoxy group) into a compound, namely the substitution of an acetyl group for an active hydrogen atom. A reaction involving the replacement of the hydrogen atom of a hydroxyl group with an acetyl group (CH3CO) yields a specific ester, the acetate. Acetic anhydride is commonly used as an acetylating agent reacting with free hydroxyl groups. For example, it is used in the synthesis of aspirin, heroin, and THC-O-acetate.
