The development of Drepanotermes perniger (Frogg.) in Australia is simple, with non-reproductive and reproductive lines separating at the first moult, a single worker line, a monomorphic soldier caste derived from two or three worker stages, and brachypterous neotenics formed by the premature metamorphosis of fifth-instar reproductive nymphs. Intercastes are known between soldier and fifth-instar reproductive nymph; presoldier and neotenic; and third-instar worker and fourth-instar reproductive nymph. All have substantially nymphal thoraces and abdomens, with minor intercaste modifications, and heads that are variously modified from nymphal towards soldier, presoldier or worker characteristics. The development of the castes shows a marked seasonal cycle, and only workers, soldiers and fourth-instar reproductive nymphs occur during the winter. Oviposition begins after the resumption of foraging in spring, and in the south growth and differentiation continue through much of the summer. Fourth-instar nymphs break diapause synchronously in early summer, and the alates fly with rains in January or February. In northern Australia there is a break in oviposition during summer, and the reproductive nymphs develop from eggs laid in autumn, after the alates have flown.

Degradation of paper caused by beam irradiation was investigated from a viewpoint of discoloration in PIXE analysis and its application to the paper samples of archaeology. Two types of paper (Japanese paper and fine quality paper) were tested in in-air PIXE analysis with 3 MeV protons. The degree of discoloration was quantitatively measured by the use of a calorimeter. The degree of discoloration was different for each tested paper and corresponded to the radiation dose of ions. It is resulted that even the in-air PIXE analysis should be carefully applied to archaeological treasures. Because discoloration of all tested paper decreased gradually at first but then increased after a few weeks. However, this phenomenon can be used to develop a technique of funny coloration.

BACKGROUND: Psychiatric disorders are not compatible with carrying firearms or with driving a car. Persons with such disorders are often not employed and are persistent in demanding invalidity pensions, but some of them also insist on holding on to the mentioned licenses. In such cases, where persons are already in possession of firearms and driving licences, it never occurs to them, that they should surrender their permits back. AIM Pointing to the importance of OM controlling firearm/car driving licenses. CASE REPORTS: This paper discusses the problem of three cases that should be widely recognised as it is potentially life-threatening to other people. The first is the case of a war veteran in retirement with PTSD that had his application for firearms licence rejected by the authorities. The second is the case of a labourer who suffers from a depressive disorder, temporarily incapable of work. The third is the case of a war veteran, a chronic alcoholic with toxic epilepsy, who is applying for invalidity retirement but wants to keep his driving license. CONCLUSION: Occupational medicine assess every single worker by applying advanced methods and psycho tests that enable a thorough assessment of work capacity and fitness for carriage of firearms, driving as well as the assessment of psychiatric disorders, which are the most delicate to assess.

The Japanese papers, "washi", are made from the plants. Since the elements included in the washi have the informations of the raw material plants, there is potentiality of the identification of the production place by the element analysis of the washi. Three kinds of washi made of kozo, which have different habitats, were prepared. The elements in their washi were measured by the PIXE. It was confirmed that the amount of elements included in the washi depend on the habitats of their raw material plants.
