  • Discovery of a new chemical entity that exerts pharmacological effects for curing or treating diseases or relieving symptoms is only the first step in the drug developmental process. In the developmental cycle of a new drug, the delivery of a desired amount of a therapeutic agent to the target at a specific time or duration is as important as its discovery. In order to realize the optimal therapeutic outcomes, a delivery system should be designed to achieve the optimal drug concentration at a predetermined rate and at the desired location....

  • Products of nanotechnology are expected to revolutionize modern medicine, as evidenced by recent scientific advances and global initiatives to support nanotechnology and nanomedicine research. The field of drug delivery is a direct beneficiary of these advancements. Due to their versatility in targeting tissues, accessing deep molecular targets, and controlling drug release, nanoparticles are helping address challenges to face the delivery of modern, as well as conventional drugs.

  • Over 98 per cent of sprayed insecticides and 95 per cent of herbicides reach a destination other than their target species, including non-target species, air, water and soil. Pesticide drift occurs when pesticides suspended in the air as particles are carried by wind to other areas, potentially contaminating them. Pesticides are one of the causes of water pollution and some pesticides are persistent organic pollutants and contribute to soil contamination. Detection of pesticide molecules in the food items from plant and animal origin become imperative for safe consumption of food.

  • Despite the advances in the development of new drugs, a drug may never reach the target organ, or it may be difficult to achieve the necessary level of drug in the body. Large doses can result in serious side effects, and can harm normal cells and organs as well as diseased cells. Hence controlled release and the targeting of delivery systems must evolve in parallel to drug research.

  • Applications that use HTML-based front ends benefit from the pervasive distribution of Web browsers for universal, cross-platform access. Another striking advantage of Web delivery lies in the concept of thin clients and centralized maintenance, facilitating instantaneous deployment of software updates at minimal cost. While the popularity of the Web and its advantages as a client-server platform have led to countless HTML-based applications, the development of Web applications is still mostly ad hoc.

  • Examples ranged from gory low-budget horror to the sexploitation films of Russ Meyer. Elements of independent ‘exploitation’ strategy were also embraced by Hollywood in its more mainstream, blockbuster productions, especially the strategy of combining wide opening release patterns with saturation advertising, in order to recoup costs quickly. A number of Hollywood’s biggest-grossing films of the 1970s were, in part, bigger-budget and glossier versions of independent exploitation fare, especially The Exorcist (1973) and Jaws (1975)....

  • The view of investor as customer also receives some weight from the fact that investors can redeem their mutual fund shares at net asset value at any time. This feature makes investing in a mutual fund unlike owning stock in a traditional company or a closed-end investment company, where the price at which an investor can liquidate reflects the market’s perception of the firm’s management. In that case, when management is revealed to have taken a “bad” action, current investors are damaged because they can resell their shares only at a much lower price.

  • Effective communication is essential to the success of all the above categories of needs analysis. The mechanisms established need to ensure proper ‘bottom up’ communication from the local level, as it is difficult to make the voice of the SME sector heard at the national level – this is particularly so for informal and micro enterprises. Information and communication technology is now beginning to change this. For a selection of websites on SMEs and their development see also Annex 9.3. Information alone is neither knowledge nor learning.

  • Switzerland's policy for improving air quality "must be pursued with determination," the agency added. "In particular, this means using more advanced technologies and introducing stricter norms for nitrogen oxide (NOx) and particulates." The agency said one reason for the smaller than anticipated decrease in polluting emissions is the projected increase in truck traffic despite the Swiss government's efforts to encourage trucks crossing through Switzerland to be put on rail cars through the use of road tolls and quotas on truck traffic.

  • The dromedary’s water intake is through drinking and the water in the feed. The need for drinking depends on environmental temperature and humidity and the water content of the feed. Under range conditions if water is readily available, camels may drink daily or may not for several days. The main water losses are from evaporative cooling of the skin, in urine and faeces, and even in these functions the conservation of water can be very efficient. During exercise physiology studies, obvious sweating was not observed.

  • Today’s customer-focused, market-driven company cannot afford to miss the fact that many customers prefer environmentally friendly products given a similar cost. Again, it is easy to see that creating and sustaining competitive advantage is still a matter of “better, cheaper, faster.” The Internet has made customers more informed about every aspect of a product, including its potential environmental harms. Companies that can meet these environmental needs will be the winners.

  • The potential benefits are large and greatly exceed the expected costs of improved fuel economy. Cutting global average automotive fuel consumption (L/100 km) by 50% (i.e. doubling MPG) would reduce emis- sions of CO2 by over 1 gigatonne (Gt) a year by 2025 and over 2 gigatonnes (Gt) by 2050, and result in savings in annual oil import bills alone worth over USD 300 billion in 2025 and 600 billion in 2050 (based on an oil price of USD 100/bbl). The Initiative proposes several steps and actions to work towards the 50:50 overall goal and each step will achieve some of...
