  • For many years, the plates of leadracid batteries have been produced from leady oxide, a mixture of finely divided lead Ž‘free-lead’. and lead monoxide. Although this material is generally satisfactory, it suffers from the disadvantages that it is variable in composition and requires complicated and lengthy processing after pasting to remove the residual free-lead. Plates made from leady oxide also require cycling before they achieve their full performance, and this can result in either depressed initial capacity or additional processing cost. ...

  • 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.

  • Abstract: Shrimp chitin and chitosan with improved characteristics were isolated from black tiger shrimp waste pretreated with 0.04 M Salicylic acid for ten hours. The pretreated shrimp shells could be efficiently demineralized and deproteinized at ambient temperature using 0.680 M HCl and 0.620 M NaOH, respectively. The duration of the treatments was 8 hours, the ash and protein residues in the final chitosan were about 0.48% and 0.51% respectively; the viscosity was 4800 cps; the solubility was up to 98%.

  • National mining associations have developed and dis- seminating charters or voluntary codes of practice to improve the level of environmental management. An example of this is the Australian Mining Industry Code for Environmental Management developed by the Minerals Council of Australia (see Appendix C). This voluntary code has been widely adopted by min- ing companies within Australia. These are required to publish public environmental reports to demonstrate progress on the implementation of the code's princi- ples.

  • In Mekong delta, mangrove forest distributes along the coastline of 700 km and it is a homeland for mud crab in tropical areas. The mud crab becomes potential to be alternative species from failed shrimp farming. Particularly, mud crab hatchery has been introduced and operated recently at Bac lieu, Tra vinh, Soc Trang, Ben Tre, Kien giang and Ca mau provinces. However, the survival from zoea stage to crablet stage 1 is low at approximately 5%. In addition, like shrimp rearing, the mud crab hatchery is using antibiotic as major treatment to prevent bacteria and fungi.

  • With regards to the samples of tomato, in crops were traditional practices were implemented, pesticide residues were found belonging to the chemical groups of OF (chlorpyrifos and phenthoate) and n-methyl carbamates (carbofuran and 3- hydroxycarbofuran), presenting the highest concentration of residues in OF. For plots with GAP the presence of residues of same pesticides n-methyl carbamates and chlorpyrifos was seen, being the only difference the finding of dimethoate.

  • For subsequent analysis of the specimen, the needles may be rinsed into a physiologic solution, tissue culture medium, transportation medium or proprietary fixative for liquid based processing. Needles should not be re-sheathed using a two handed technique and instead should be discarded directly into an OSHA approved sharps disposal container. 9 For cystic lesions, remove as much fluid as possible. The cyst fluid can be handled as a liquid specimen. If there is a residual mass, the procedure for solid lesions as described above should be followed.

  • The inclusion of a smooth function of time in a regression model introduces important sta- tistical issues.We generally do not know precisely the complexity of the seasonal and long-term trends in themortality time series or in the pollution time series. Therefore, a controversial issue is determining how much smoothness we should allow for the smooth function of time. This decision is critical because it determines the amount of residual temporal variation in mortality that is available to estimate the air pollution effect.

  • In many ways, local authorities are well placed to pursue measures which improve air quality and reduce greenhouse gas emissions. For example, policies designed to reduce the impact that transport has on air quality by tackling congestion and encouraging a shift to public transport, walking and cycling should also reduce carbon dioxide emissions. Measures to improve energy efficiency and cut energy demand should also reduce air pollutants that are produced during electricity generation.

  • The former NOP director Audit Report 01601-03-Hy 3 7 stated that the decision not to require regular residue testing was based on officials’ concerns about the cost of testing, and their position that the NOP regulations are process-based rather than a zero tolerance standard. The former director also stated that certifying agents did not want to pay for the cost of residue testing and that residue testing raises complex issues that must be addressed on an operation-by-operation basis.

  • The 1990’s were a troubled decade for the Big Three TV networks, NBC, ABC, and CBS. For the first time since they began keeping records, their combined prime-time ratings dropped below 50 percent. There were many reasons for this change, but the most important one is that TV and the other older media are being challenged by the Internet and other technologies that offer an expanded range of information and entertainment services. Newspaper (print) Other media are similarly affected.

  • In two cycles of an error-prone PCR process, variants of formate dehy-drogenase from Candida boidiniiwere created which revealed an up to 4.4-fold (440%) higher residual activity after entrapment in polyacrylamide gels than the wild-type enzyme. These were identified in an assay using sin-gle precursor molecules of polyacrylamide instead of the complete gel for selection.

  • Most manufacturing technologies for metallic microstructures have their roots either in semiconductor (inmost cases, silicon) device production or in conventional precision machining. Of these, the techniques that are well known have been used formicrostructure dimensions. Further, they have been adapted and improved to reach the desired precision and surface quality. In some rare cases, itwas possible to use the same manufacturing process for macroscale and microscale devices and to get the desired results.

  • Twelve studies addressed the contextual influences which hinder or enable the develop- ment of reflection and reflective capability. Several studies explored the effect of context on reflection and reflective thinking. Sobral (2000) found evidence for improved quality of learning as students strive for control of their learning. He suggests that a greater effort at reflection is associated with a more positive learning experience, and that reflection in learning is related to readiness for self- regulated learning, and to the meaningfulness of the experience.

  • CARE has found that VSLAs meet the need for savings and credit at the very bottom rung of the world’s economic ladder. They create a platform from which the poor can advance to receive the more sophisticated financial services that they inevitably need as their resources, skills and confidence grow. The next step, therefore, is the linking of VSLAs to microfinance institutions and banks so that the poorest people in Africa can have access to all of the financial services that can help them improve their lives. To take this next step, in 2008 CARE launched an ambitious...
