The intake system sub-model, the fuel dynamics sub-model and the power output sub-model are studied in this paper based on Elbert Hendricks engine mean model. Engine output characteristics using computational model is established in MATLAB/Simulink. Parameter of the modeling and simulation process is obtained through experiments, and finally, the engine bench test is done, and compared it with the simulation curve in same conditions. The results show that the model calculation has smaller error, higher precision, and which can meet the basic requirements of the engine modeling in actual control.

THE broad-toothed rat Mastacomys fuscus is a native, herbivorous rodent that occurs in New South Wales, Victoria and Tasmania. On the Australian mainland the species has been recorded in several habitats at altitudes ranging from sea level to 1800 m. In alpine and sub-alpine areas of New South Wales and Victoria it has been recorded in heathlands, open eucalypt woodlands and wet sedgelands (Calaby and Wimbush 1964; Dixon 1971; Seebeck 1971; Bubela et al. 1991). At lower altitudes in Victoria, it has been recorded in wet sclerophyll forests with a dense undergrowth, coastal heathland, coastal grassland and in a pine plantation (Seebeck 1971; Wallis et al. 1982; Warneke 1960). In Tasmania, M. fuscus has been previously recorded only in buttongrass moorlands of western Tasmania at altitudes ranging from sea level to 900 m (Finlayson 1933; Andrews 1968; Green 1968, 1984; Hocking and Guiler 1983; Driessen and Comfort 1991; Slater 1992; Driessen 1998). Buttongrass moorland (also referred to as sedgeland) is a treeless vegetation typically dominated by Gymnoschoenus sphaerocephalus (buttongrass) that covers more than a million hectares in Tasmania, predominantly in the western part of the State (Jarman et al. 1988). Buttongrass moorland is a very variable vegetation group and not all communities recognised within buttongrass moorland provide habitat for M. fuscus (Driessen and Comfort 1991; Slater 1992; Driessen 1998). The purpose of this note is to report the results of a survey for M. fuscus in alpine heathland, a habitat in which the species has not been previously recorded in Tasmania. This finding has significant implications for the conservation status of this species.

Utilisation of orthophosphate, inositol hexaphosphate and DNA by isolates of Amanita alboverrucosa, A. conicoverrucosa, A. fuscosquamosa, A. muscaria, A. nauseosa, A. ochrophylla, A. pyramidifera, A.�roseolamellata, A. xanthocephala and six unidentified Amanita species from eastern Australian temperate sclerophyll forests was examined during growth in axenic liquid cultures. With the exception of A. nauseosa and A.�xanthocephala on DNA, isolates of all taxa were shown to utilise orthophosphate and both organic substrates as sole phosphorus sources. Considerable intraspecific variation in utilisation of the organic phosphorus sources relative to orthophosphate was observed for A. muscaria and the native Australian taxa. Overall the data suggest that Amanita spp. may contribute significantly to organic phosphorus mobilisation in Australian forest soils.

The distribution and abundance of the carabid beetle fauna of selected grassy ecosystems, wet and dry sclerophyll forests, and wet heaths in the Eastern Tiers, Tasmania was examined using pitfall traps. The conservation values of the sites were assessed by applying evaluation criteria typically used for vegetation (i.e., representativeness, typicalness, diversity and rarity) to both the carabid fauna data and the vegetation data. Sites of high conservation value for carabids and vegetation were identified and compared. Sites that ranked highest in terms of the carabid fauna on all conservation criteria were not the sites that ranked highest based on the vegetation. Classification of sites produced different results depending on whether plant or carabid data were used. Conservation based solely on vegetation attributes will therefore not necessarily conserve a rich and/or representative carabid fauna. If the objective to conserve a representative range of all biota is to be met, the use of additional taxa such as carabids in conservation assessments is desirable.

At 38 sites in the dry sclerophylJ forests of south-east Queensland, Australia, hollow-bearing trees were studied to determine the effects of past forestry practices on their density, size and spatial distribution. The density of hollow-bearing trees was reduced at sites that had been altered by poisoning and ringbarking of unmerchantable trees. This was especially the case for living hollow-bearing trees that were now at densities too low to support the full range of arboreal marsupials. Although there are presently enough hollow-bearing stags (i.e., dead hollow-bearing trees) to provide additional denning and nesting opportunities, the standing life of these hollow-bearing stags is lower than the living counterparts which means denning and nesting sites may be limited in the near future. The mean diameter at breast height (DBH) of hollow-bearing stags was significantly less than that of living hollow-bearing trees. This indicated that many large hollow-bearing stags may have a shorter standing life than smaller hollow-bearing stags. Hollow-bearing trees appear to be randomly distributed throughout the forest in both silviculturally treated and untreated areas. This finding is at odds with the suggestion by some forest managers that hollow-bearing trees should have a clumped distribution in dry sclerophyll forests of south-east Queensland.

Abstract Removal of dead and live biomass from forested stands affects subsequent fuel dynamics and fire potential. The amount of material left onsite after biomass removal operations can influence the intensity and severity of subsequent unplanned wildfires or prescribed burns. We developed a set of biomass removal treatment scenarios and simulated their effects on a number of stands that represent two major forests types of the northern Rocky Mountains: lodgepole and ponderosa pine. The Fire and Fuels Extension to the Forest Vegetation Simulator was used to simulate effects including stand development, fire behavior, and fire effects prior to the biomass removal treatment and 1, 10, 30, and 60 years after the treatment. Analysis of variance was used to determine whether these changes in fuel dynamics and fire potential differed significantly from each other. Results indicated that fire and fuel characteristics varied within and between forest types and depended on the nature of the treatment, as well as time since treatment. Biomass removal decreased fire potential in the short term, but results were mixed over the long term.
