Airports across the UK are still on high alert after Scottish nurse Pauline Cafferkey became the first person to be diagnosed with the deadly Ebola virus on UK soil. We ask Professor Paul Cosford, director for health protection and medical director for Public Health England, if screening procedures at Heathrow and other UK hubs are sufficiently robust to protect passengers and staff.

The summer season each year brings wafting memories of a juicy and luscious fruit called litchi. The origins of Litchi lie in southern China where as a crop it has been cultivated uninterruptedly for close to 2500 years. Its geographical propagation has been rather slow, which is due to the short life-span of its seed and the peculiar soil and climatic requirements associated with the plant.A classical instance of this is India which is the second largest producer just behind China, but litchi farming is chronologically speaking, very recent having been introduced only sometime in the middle of the 1700's. Together China and India between themselves produce more than 90% of the world's Litchi, leaving the rest of the world far behind. In the backdrop of all this it is interesting to know the various cultivars and varieties which dot the world of Litchi farming. Most or all of them have their genesis probably in China but have been suitably bred and modified to thrive in countries of their adoption. The terms 'cultivar' and 'variety' have often been used interchangeably but this convention often seems to ignore the obvious differences which exist between the two. A 'cultivar' is bred with the help of vegetative propagation, which could include cutting, grafting,budding and tissue culture and is a product of human effort and ingenuity. A 'variety' on the other hand is a natural phenomenon and is bred through seedlings. A 'variety' will always produce clones of the parent plant, but in a cultivar,there may be slight variation in a progeny compared to the parent particularly in the case of hybrids. The Litchi cultivars in India number about 40 out of which around 12 or 13 are commercially cultivated.The same cultivar or variety may be known by different names in various parts of the country. In China there are about 200 known cultivars although only 20 or so are in commercial farming, which means the genetic repository is much more widespread compared to India but

Application of VAM used in the production of polyvinyl alcohol, coatings and adhesives.It is an important organic chemical material.Vinyl acetate by its polymerization or copolymerization with other monomers,mainly use for the production of polyvinyl acetate (PVAc),polyvinyl alcohol (PVA),vinyl acetate - ethylene copolymer emulsion (VAE) or vinyl acetate copolymer (EVA) resin,vinyl chloride copolymer (EVC), acetal resins such as derivatives. These derivatives usage is very extensive and can be used for bonding agent, and glue pharmaceutical of paper or fabric, coating, ink, leather processing, fibre processing, emulsifier, water soluble film, soil conditioner,.VAM is an important synthetic material monomer. with the progress of science and technology, other downstream products and new applications are still in constant development.
