What is the concern about Flu?

By Gilberto Silber Schmidt
Labex Korea The controversy regarding the H5N1 virus remains to be discussed by the main newspapers and magazines connected with Science and Technology and with the poultry productive chain. The analysis of this event takes different paths, depending of the view of the impact on the different segments. The Labex Korea continues to follow this controversy, offering its readers the most important data published in the media.
Several sectors, involved in this controversy, has requested the stopped or restriction in studies and / or publications of this nature. Dr. Daniel R. Perez, in his article entitled H5N1 Debates: Hung Up on the Wrong Questions  reports a series of arguments that clearly demonstrate the need to continue this kind of research, especially considering the benefit to public health worldwide, with a focus on eradication, development of vaccines and medicines that can prevent a pandemic, that can drastically affect the entire world population.

The possibility of a pandemic only be effective if the virus acquire the ability by aerosol transmission between humans, therefore, the development of studies to understand the molecular attributes to ability  the H5N1 virus into this new situation is the key to predicting and (or) prevent the onset of pandemic strains.

Itaipu and Embrapa lead projects to increase the use of biogas and no-tillage

Biomass & Bionergy – A partnership between Itaipu and the Brazilian Agricultural Research Corporation (Embrapa) will enhance the use of biogas and tillage system in Brazil. In the case of projects on tillage, initiatives will also have the support of the Brazilian Federation of Direct Planting in straw (FEBRAPDP). The actions are included within the Federal Government program to reduce emissions of greenhouse gases. By 2020, the Brazilian Agricultural sector should stop issuing 1 billion tons of CO2, within the Low Carbon Agriculture Program (ABC)
The project involves the participation a total of 20 researchers from Embrapa and will be coordinated by the Office of Renewable Energy and the General Board of th Brazilian Binacional (Itaipu). The research project involve the development of technologies for treatment of animal waste, with emphasis on the production of biogas and fertilizer, and further research and technology transfer in no-tillage system.
The projects are large and predict, for example, the creation of new technologies for biogas production chain. Among the initiatives that were discussed is the development of new digesters, more energy efficient and more appropriate to the diverse realities of Brazil. Another aspect of research aims to develop new biological reactors, with high efficiency, and new technologies for filtering of biogas for the production of biomethane vehicles. Some of research points will be permanent, according to Cicero Bley Júnior, Renewable Energies superintendent of Itaipu. “Japan, for example, considers the biogas as an important source of energy. And the digesters have constantly evolved, “said Bley Júnior.
The acquired knowledge by Itaipu project with the production of biogas in the Paraná Basin 3, should contribute to the research. Since 2009, the company develops the Condominium Agroenergy Ajuricaba River, already operating in Marechal Candido Rondon (PR). At the site, 27 families have built a biodigester integrated on the property and are producing 690 cubic meters of biogas from animal waste. Still cannot define how many farms will be benefited in Brazil, since each step must involve dozens of researchers, according to Embrapa.
“These projects will be an attempt to solve the problems that exist today in this sector. Then, they will gain additional projects and cover a larger group, always in partnership. We count on support from university researchers as Unioeste the Londrina State University and many others, “said the researcher in the Department of Research and Development of Embrapa, Jose Americo Bordini do Amaral.
