The main source of atmospheric mineral dust is the Sahara and its desertified margins that produce about half of the yearly global mineral dust. Saharan dust is often transported far away to the sources and causes air quality deterioration impacting northwards the Mediterranean and Europe, westwards crossing the Atlantic Ocean to the United States, the Caribbean and South America, and southwards to the Gulf of Guinea. Saharan dust storms can lead to particulate levels that exceed internationally recommended levels and transport allergens, including bacteria and fungi. Therefore special attention is paid to dust storms as such mineral particulate matter air pollution may be a serious health threat in various regions of the world because it may promote respiratory infection, cardiovascular disease and other ailments.

We present a solution to improve the performances of coronagraphs in general for the detection of exo-planets. We simulate several kinds of coronagraphic systems using an IDL software, with the aim of evaluating the gain obtained using an adaptive hologram. The detection limit in flux ratio between a star and a planet observed with an apodized Lyot coronagraph characterized by wavefront bumpiness imperfections of lambda/20 (resp. lambda /100) turns out to be increased by a factor 1`000 (resp. 1`000`000) when equipped with an hologram. This technique could provide a direct imaging of an exo-earth at a distance of 11 parsec with a space telescope with a mirror quality analog to the HST, and with a diameter analog to the JWST.

The aim of this presentation is to introduce the International Liquid Mirror Telescope (ILMT) project and to establish the latest advances in its hardware development. The presentation will begin with a brief introduction on the basics of liquid mirrors. The elements required to complete the mirror in order to get a functional liquid mirror telescope will then be reviewed. The particularities of Liquid Mirror Telescopes will then be discussed and the advantages they represent for specific scientific objectives will be explained. In particular, the ILMT scientific drivers will be presented. Once the project and its scientific interest will have been introduced, we will talk about the current status of the ILMT hardware: the status of the container, the mechanical structure, the optical corrector and the CCD camera will be briefly summarized. The recent evolution will be emphasized. Finally, we will address what still needs to be done in the ILMT development. [less ▲]

In 2006, the poultry population of Vietnam was about 215 million heads. However, between 2004 and 2008, the Highly Pathogenic Avian Influenza (HPAI) caused by H5N1 virus was broken in affected almost all provinces in Vietnam with millions of birds culled. This had large economical and sociological impacts. A question has been raised: how could Vietnam limit this epidemic? The research aims to identify the poultry production systems with their various constraints, including diseases and to evaluate the cost-benefit impact of a mass vaccination programme implemented from March to August 2007 at local level in Long An Province within the Mekong Delta. Two principal poultry farming systems are characterised: the commercial poultry production system (system 1) with low to moderate bio-security level, and the small-scale production system (system 2) with a low bio-security level. The scenarios of cost-benefit analysis of vaccination campaigns against HAPI caused by H5N1 virus give a good strategy for the restructure of poultry production and farmers’ incentives to vaccinate. The vaccination is more cost effective for the farmer than culling operations, with the BCR scenarios are between 31 to 78 times more. [less ▲]

Ban swine is raised by households of ethnic minorities, especially Muong, in the remote communes of Hoa Binh province. This breed has several advantages such as good resistance to diseases, good quality of meat. This research was conducted from July 2007 to June 2008 to determine characteristics, distribution, reproductive performance of this swine breed through by the conventional method of survey such as recording body weight data and measuring the length and chest size on weekly and monthly bases. Ban swine has a black color of coat with white feet and belly. Their hairs are long and hard. They have small and erected ears, small face, long mouth, and weak back. The age at first farrowing was 13 months. The reproductive performance was low with a litter size of 5.58 for the first litter and 9.06 for the fourth (P<0.05). The average birth weight was 0.43 kg, weaning weight at 86.33 days of age was 5.05 kg. The farrowing interval was very long (241 days) with 40.46 days from weaning to re-breeding The average monthly gain was 1.49 kg for the suckling period. Feed Converson Ratio (FCR) up to weaning was very high (19 kg concentrate and 57.4 kg of forage/kg live weight). [less ▲]
