One afternoon, a photography enthusiast, Mr. Cheung was holding some photos, completely absorbed in the fond (but ancient) memories of his honeymoon in Cairo. The badly-yellowed photo prints reminded him of every sweet and romantic moment of the “good old days”. He was soon rudely awakened when Mrs. Cheung shouted, “Honey dear! I was told that high-tech is ‘in’, and the single-lens reflex camera is totally out! So stop hugging the old out-dated pictures.” Mr. Cheung fired back, “Oh, you know nothing. This is something you cannot replace at all, and my camera is a classic.” Smiling at him, Mrs. Cheung took out a new gadget, “Right, right, now calm down. It never hurts to have both worlds. Look what I’ve got you. This is called ‘Stereoscopic Camera Lens’. Its little coloured spectacles can capture everything, say, the sensational Great Pyramid, in three dimensions!” As we are asking for and relying more on technological advances, the Stereoscopic Camera lens and the Stereoscopic Magic Box are surely innovations that promise to add a new dimension to our lives. Surprisingly, the working of these two gadgets involve only some simple scientific theories such as polarization, doping and anaglyph; and employs the special property of Liquid Crystal Layer (LCD) under electric current. Stereoscopic photos can now be easily available to us. Both of our designs, the Stereoscopic Camera Lens and the Stereoscopic Magic Box, can turn something ordinary into extraordinary by making plain, 2-dimensional things ‘stand out’ before your eyes. The Lens itself is crafted with such precision that it can capture any image both faithfully and flawlessly. The Magic Box uses electric current to catalyze and enhance the 3-dimensional transformation. So each picture is vibrant and true-to-life. The Lens and the Magic Box will certainly revolutionize our vision of things around us. To enable you to have a good understanding of the theories behind the making of the Stereoscopic Camera Lens and the Stereoscopic Magic Box, we have made simple models of them with prisms, and they are in display at our booth. Anyone who is interested in these fancy gadgets should definitely come to our booth to experience a new view of the world!

My project is about investigation on traditional medicines in\r Namibia. This is all about plants and different herbs that different\r people in Namibia use for medicinal purposes. The objective of this\r project is to inform the world of how valuable nature is and how we can\r try to conserve nature’s treasure so that valuable knowledge cannot pass\r away with olden experienced herbalists. Understandably the enquiry\r into indigenous medicinal herbs arose from the need to expand the\r possibilities of ones own medical practice. It was very important for me\r to satisfy our farmer’s thirst for knowledge, which is what I want to do\r with the rest of the world.\r In this project I have included most but not all of the plants that we\r use in Namibia for medicinal purposes. Seeing that some of these plants\r do not grow in certain parts of the country, I have also tried to clone it in\r other parts of the country. I have also made a powder from one of the\r plant’s leaves and tested it on several people within the country.\r To conclude my findings and experiments I would like to say, let us\r try to take these precious knowledge left for us from our ancestors and\r maybe one day in the future we might need it in some ways.

Chitin, a polysaccharide common in biocomposites, has an interwoven organic framework that can act as a scaffold for mineralization in natural systems. Acidic amino acids, namely aspartic (Asp) and glutamic (Glu) acids, are the primary active molecules at biomineralisation interphases in mollusks and play an important role in controlling the polymorph and morphology of the associated mineral.\r In this study, chitin was extracted from squid pens and used as a scaffold for crystallization. The chitin scaffold was functionalized with glutamic acid and aspartic acid separately to create an artificial microenvironment for the study of biomineralization of calcium carbonate. The objective was to investigate the usefulness of the extracted chitin to serve as a scaffold for calcium carbonate crystallization, especially the fidelity of the polymorph nucleated to the amino acids and proteins used.

Farmers in many countries are legally required to identify livestock with some sort of tagging system. Tagging is required for ownership, breeding and as a means of tracking livestock during a disease outbreak.\r New Zealand farmers are required to fit all livestock with two ear tags (one in each ear). Ear tags are applied in a similar way to the piercing of human ears. The two tags are of different sizes and are known as the primary and the secondary tags. The primary tag is physically bigger than the secondary tag.\r We farm deer and have noticed that after tagging some deer develop ear infections at the site of tagging.\r A randomized controlled trial was undertaken in 105 fawns to test the hypotheses:\r ‧ Pre treatment of the ear tag with liquid iodine will reduce post tagging infection.\r ‧ A reduction in ear infections as a result of tagging will lead to more rapid weight gain.\r The treatment group had iodine applied to the sharp part of both primary and secondary tags immediately prior to tagging of the fawns. The control group was tagged in the usual fashion. Fawns were then assessed for infection at 6 and 11 weeks after tagging. Each ear was individually graded for infection and recorded against the number of the animal. Grading was on a scale of 0-3: zero having no infection; 1-slight redness; 2-a larger ring of redness and possibly some dried blood; 3-as for grade 2 plus swelling of the ear around the pin.

The purpose of this research was to investigate the most favourable salt concentration that promotes growth in the Lemna minor plant. Lemna minor, commonly known as lesser duckweed, is found growing among other aquatic plants or massed together in still or slow moving fresh water, such as ponds and lakes, in warmer regions around the world.

CD157 is a 31kDa ectoenzyme that is expressed at elevated levels in patients\r with rheumatoid arthritis (RA). The full function of this protein has yet to be\r determined, and the correlation between CD157 and RA is not well\r understood.
