【正文】 logy is evaluating the potential for improving soil structure and crop productivity through the management of earthworms. Objectives of the research are:? To determine the distributions and population dynamics of earthworms in agricultural soils, especially beneath pastures, horticultural and cereal crops in southeastern Australia. To demonstrate the effects of selected earthworms on soil structure,fertility so, and plant production.? To identify means of enhancing earthworm performance, either by agricultural management practices or introduction of new species/strains.? To investigate the use of posting worms to reduce anic wastes and the use of wormworked waste as a soil conditioner? Results so far have been promising. Current studies with selected earthworm species have shown increases in cereal yields by more than 35%. Selected earthworm species have also been shown to improve crop quality, with higher levels of grain protein.

The types refer to different antigens that sit on the surface of the millions of red blood cells in our bodies. An antigen is a protein that prompts the body to produce an antibody. If you have blood type A, your plasma carries B antibodies so that if you e into contact with typeB blood, the antibodies seek and destroy the B red blood cells. Contact between the two blood types can have serious consequences, including kidney failure and shock. People with type AB have both A and B antigens while O type blood have neither. An Austrian pathologist identified the first two red cell antigens, A and B, in 1900. In the 1940s, he identified a further class of antigen, the rhesus (Rh) factor, named after the monkeys in which the discovery was made. Rhesus factor is in the red blood cells of most people, but about 15 per cent of people are rhesusnegative. If you are rhesusnegative and receive rhesuspositive blood, you will produce antirhesus antibodies. The first time is not usually crucial, because by then the donated blood is diluted. But if you receive further transfusions of Rhpositive blood, the antirhesus antibodies will attack the positive blood cells, causing agglutination or clumping, which can be fatal. The biggest problem arises during pregnancy. An Rhnegative woman with an Rhpositive partner is likely to conceive an Rhpositive baby. In late pregnancy, small amounts of the baby39。s Australian Sports Drug Agency and a farmer. All are success stories, but their attitudes to business and women in business are as diverse as the industries in which they work. Women have been very successful at gaining senior roles in some parts of anisations, such as human resources, law and public affairs, but those roles are not core operational positions and are generally not a path to the managing director39。 concerns about the funding of publicsector science, the threat of declining strategic and basic research relative to applied science, and specific issues such as external earnings targets for CSIRO. Australia continues to sit on intellectual property, not knowing what to do with it, or gives it away to more entrepreneurial nations. This is not due to lack of funding but lack of appropriately placed business expertise. This is partly due to factors of culture and attitude. When Australian science is deployed with the support of very scarce domestic venture capital, it often ends up in trouble. When our science links to international venture capital, we tend not to secure a partnership that allows us to capture the benefit and develop mercialisation petencies. Given the attitudes of scientists and publicsector science managers, this shorting is no surprise. An endemic cultural antipathy exists between Australian publicsector and academic scientists and the world of business. While this is not exclusive to Australia, it seems to be particularly strong here. There are some exceptions, but as a general phenomenon it is difficult to overstate the problem. Why is this happening? What are the drivers? Australia does suffer from ugly entrepreneur syndrome, while for Americans, with whom our science petes, entrepreneur has positive associations. 16 WHO revises SARS case definition WHO has today updated its case definition for SARS to take into account the appropriate use of results from laboratory tests. Several diagnostic tests have been developed by various laboratories for the detection of the SARS virus and antibodies to the virus. However, all presently available tests have specific strengths and weaknesses. For this reason, WHO continues to advise clinicians that patients should not have their case definition category downgraded while awaiting results of laboratory testing or on the basis of negative results. WHO is concerned that inappropriate use of laboratory results can have a negative impact on patient management and selection of an appropriate level of infection control. Therefore, negative test results for the SARS virus cannot be used to exclude infection in either suspect or probable cases. In contrast, positive results of quality – assured laboratory testing can add to the efficacy of SARS case management, provided tests are properly conducted and interpreted. Positive virus results from lab tests demonstrate that the patient is excreting virus, or its geic material, and thus might pose a risk of disease transmission to others. Consequently, suspect SARS cases with a positive lab result (virus isolation or PCR) should be classified and reported as probable cases.
