The market for ultraviolet curing technology has been growing at double-digit rates in the last 10 years. The main reason for such a rapid technological growth of UV curing is its unique process characteristic, which allow UV-coating to be applied on virtually any substrates, including plastic, metal, composite, wood, paper, leather, vinyl, glass, magnetic recording tape and even human teeth. The original driving forces behind the commercialisation of UV-technology were energy saving and freedom from solvents. These benefits are complemented by high productivity and subsequently higher profits that can be achieved with the increased line speed, just-in-time benefits and immediate "pack and ship" capabilities. This paper gives a review of the development of the UV curing technology, with emphasis placed on relevant chemistry.

Development of new radiation-curable materials for the application in radiation curing technology is of significant importance. Most of the commercially available radiationcurable resins are derived from synthetic raw materials. The synthesis of acrylated, epoxidised soybean oil (ESO) from ESO had been carried out by reacting acrylic acid with the oxirane group in ESO. The acrylated ESO products were characterised using a variety of analytical techniques. Thus, the oxygen value, the iodine value, the acid value and the infrared spectra of the acrylated ESO products were obtained. Pigmented acrylated ESO systems were prepared and found to cure on exposure to UV radiation.

C ryptococcosis is a prominent cause of fungal meningoencephalitis with a significant disease burden globally (1). Although this infection is more often an opportunistic consequence of HIV/AIDS infection, it has also been reported in apparently immunocompetent populations (2). Currently, it is reported that approximately 20% of cases occur in clinically nonimmunocompromised patients (3,4), and the disease course in these patients has been associated with poorer cerebro-spinal fluid (CSF) inflammatory responses and mortality rates (5).Cryptococcal meningitis (CM) most frequently manifests in patients as headaches, fever, nausea, vomiting, and visual impairment. When the eye is involved, patients may experience photophobia, diplopia, ptosis, nystagmus, and ophthalmoplegia (6). Isolated ocular cryptococcus with no neurological involvement has been reported (7). In previously healthy adults with CM, ocular manifestations include optic neuropathy, cranial nerve VI palsies, chorioretinitis, vitritis, posterior uveitis, and papilledema (8,9).Although there are several case reports in the literature describing ocular findings in previously patients with healthy CM, rare reports exist depicting these findings in a substantial cohort. In this study of 44 previously healthy patients with CM, we identify abnormal ocular examination findings, attempt to detect an association with key CSF markers, and MRI findings.

Cement production is synonymous to green house emissions and mineral resource depletion. So as to produce about 1tonne of cement, 1.5 tonne is required and nearly 1tonne green house gases are emitted out. This article present sustainable use of calcium meta silicate mineral "wollastonite" (CaSio3) as a partial replacement of cement. Six concrete mixes were prepared by replacing cement with wollastonite (0-25%). Test result showed that 10% wollastonite can effectively replace cement with improvement in strength and durability parameters. Incorporation of wollastonite in cement production will help in sustainable development of country.
