ABSTRACT The aim of this study was to identify the species offrogs that can be found at streams, ridges and disturbed habitats of Gaya Island. Field sampling was carried out for 16 nights consecutively starting from 18thJanuary until 3rd February 2013. This research was conducted using the standard method of Visual Encounter Survey. The sampling effort for this study was 53 hours. Six sites representing three different frogs’ habitats were selected, namely streams, ridges and disturbed areas. The transect line with dimensions of 10m x 100m was used for the sampling survey. The results show that there were five species of frogs from two families that were present in Gaya Island. The five species were Inger’s dwarf frog (Ingerana baluensis), Grass frog (Fejervarya limnocharis), Mangrove frog (Fejervarya cancrivora), Green paddy frog (Hylarana erythraea) and Dark-eared tree frog (Polypedates macrotis). The highest number of frogs caught was in the stream area, consisting of 69 individuals, followed by 18 individuals at the disturbed area and two individuals at the ridges. This preliminary study indicated that there was a relationship between frog species diversity with the variety of the habitat sites. These findings present a baseline data for the frog species in Gaya Island. Future studies should be encouraged in order to have an in-depth understanding of the frogs’ natural habitats in Gaya Island.

ABSTRACT. Airborne gravimetry is an effective tool for mapping local gravity fields using a combination of airborne sensors, aircraft and positioning systems. It is suitable for gravity surveys over difficult terrains and areas mixed with land and ocean. This paper describes the geological mapping of Sabah using airborne gravity surveys. Airborne gravity data over land areas of Sabah has been combined with the marine airborne gravity data to provide a seamless land-to-sea gravity field coverage in order to produce the geological mapping. Free-air and Bouguer anomaly maps (density 2.67 g/cm3) have been derived from the airborne data both as simple ad-hoc plots (at aircraft altitude), and as final plots from the downward continued airborne data, processed as part of the geoids determination. Data are gridded at 0.025 degree spacing which is about 2.7 km and the data resolution of the filtered airborne gravity data were 5-6 km. The airborne gravity survey database for land and marine areas has been compiled using ArcGIS geodatabase format in order to produce the update geological map of Sabah.

ATOMISTIC SCALE STUDY OF LOCAL HEATING INTO SILICON:NANOINDENTATION USING MOLECULAR DYNAMICS SIMULATION

ABSTRACT.This paper presentsthe atomistic scale study of the effects of local heating during nanoindentation into Silicon (Si). Nanoindentation techniques and experiments with fundamental principles of MD simulations were at first introduced.The indentation processesof indentation depths an order of magnitude much smaller than experimental values and over indentation times several orders of magnitude shorter. The effects of local heating were studied using Force-Depths (F-D) curves and snapshots. The influences of the indentation speeds and temperature on the deformative behaviour of Silicon (Si) were also discussed. The force-depth curves signified the temperature influence on silicon during retraction for thermalized speeds, implying that the topology of the silicon surface did not change after tip retraction. Snapshots of the simulations into Si showed that slower indentation speeds would exhibit a decrease in the number of heated atoms.

KEYWORDS.Nanoindentation, indentation depths, indentation speeds, thermalized,simulations.
