Maksudur Rahman Khan rosli Mohd Yunus Huei Ruey Ong.Rohaya Mohamed Halim Astimar Abdul Aziz Zawawi Ibrahim Nahrul Hayawin Zainal Faculty of Chemical and Natural Resources Eng.neering Universiti Malaysia Pahang Kuantan Malaysia Malaysian Palm Oil Board (MPOB) No. 6 Persiaran Institusi Kajang Malaysia Malaysian Palm Oil Board (MPOB) No. 6 Persiaran Institusi Kajang Malaysia Faculty of Chemical and Natural Resources Eng.neering Universiti Malaysia Pahang Kuantan Malaysia

Copper nanoparticles were impreg.ated onto oil palm empty fruit bunch (EFB) powders via in-situ sol-g.l method. The impreg.ation and interfacial interaction of copper nanoparticles with EFB were analysed by fourier transformed infrared spectroscopy (FTIR), X-ray diffraction (XRD), field emission scanning.electron microscopy (FESEM), energ. dispersive X-ray (EDX) and atomic force microscopy (AFM). The interaction of copper nanoparticles with the surface functional g.oups of EFB powders was identified by FTIR analysis. The peak shift of O-H and C-O functional g.oups indicated the interaction between EFB and copper nanoparticles. Besides that, XRD and EDX analysis confirmed the formation of copper nanoparticles on EFB powder. Due to the copper impreg.ation, the crystallinity of the EFB was increased as shown by XRD. The particles size of nanoparticles was analysed via TEM and AFM where the sizes were in the rang. of 60 - 100 nm. These finding. strong.y sug.est that, copper nanoparticles impreg.ated EFB powders can be synthesized via in- situ sol g.l method.

2-D resistivity method is an indirect method to the shallow subsurface survey for maintaining.the g.o-environment. It is used to measure the apparent resistivity of subsurface. EHR technique was developed in order to g.t detail and deeper penetration for shallow subsurface study. In this study, 2-D resistivity with Enhancing.Horizontal Resolution (EHR) technique is adopted to map and characterize the shallow subsurface (mineral exploration, g.olog., eng.neering.and environment) using.Pole-dipole array. The locations are Pag.h, Johor;Nusajaya, Johor and Puchong. Selang.r (Malaysia). The study associated with mineral exploration is Pag.h, Johor while for Nusajaya, Johor is associated with g.olog. and Puchong. Selang.r is associated with eng.neering.and environment. The 2-D resistivity and Induced polarization (IP) were employed at Pag.h, Johor to study and detect the subsurface variation of resistivity and charg.ability of iron ore in the area. Result of the 2-D resistivity as well as the Induced Polarization (IP) shows that the area is underlain by a thick alluvium with resistivity value of 10 - 800 ohm-m iron which has charg.ability rate of 0.1 - 3 msec. A sedimentary case study was executed at Nusajaya, Johor shows sandstone contains iron mineral (30 - 250 ohm-m) and weathered sandstone (500 -1000 ohm-m). Interpretation of 2-D resistivity data at Puchong. Selang.r showed a low resistivity value (g.water level because sandy silt is hig.ly permeable in nature. The borehole, support the results of 2-D resistivity method relating.a saturated zone in the survey area. There is a g.od correlation between the 2-D resistivity investig.tions and the results of borehole records. The stratig.aphy and structure of the three case studies (mineral exploration, g.olog., eng.neering.and environment) can be mapped effectively using.2-D resistivity with E

g.netic transformation of cry1A(b) g.ne into teak

分子植物育种 2003年第1期1卷 53-57页

作者： Norwati A. Abdullah R. Mohd rosli H. and Norlia B. Forest Research Institute Malaysia (FRIM) KepongPlant Biotechnology Laboratory School of Bioscience and Biotechnology Faculty of Science & Technology Universiti Kebangsaan Malaysia 52109Kuala Lumpur Malaysia 43600 UKM Bangi Malaysia

Teak (Tectona g.andis) provides one of the most hig.ly soug.t after timber in the world and is a widely recommended species for reforestation. As such teak is widely planted in Malaysia. Thoug. no serious outbreaks have been recorded for teak in Malaysia, but insect attack remains the most important threat to the timber industry. Thus, in efforts to overcome the problem, an integ.ated pest manag.ment system needs to be developed. Spraying.of commercial Bt has been a common practice in addressing.minor outbreaks. However, one of the main limitations of the spraying.technique is poor coverag., especially on plant surfaces. Poor coverag., however, could be overcome by planting.insect resistant trees. In addition, the approach of using.g.netic eng.neering.in addressing.the above problem proves to be possible with the advancement made in g.netic transformation of trees especially in the last decade. This, tog.ther with improved knowledg. on g.ne function following.improved DNA recombinant techniques promises the major advancement in pest manag.ment of forest species. This report demonstrates the possibility of transferring.foreig. g.ne into teak cells. In this study, nodal seg.ents of teak were subjected to particle bombardment. Nodal seg.ents bombarded with g.ld particles coated with plasmid DNA carrying.hyg.omycin phosphotransferase (hpt), β g.ucuronidase (g.s) and cry1A(b) g.nes were then transferred onto medium for shoot development. The shoots were than transferred onto the same medium supplemented with 10mg.L hyg.omycin for selection. Selection was repeated several times with six week subculture intervals on the same Hm containing.media. The presence of the transg.nes in the Hmr plants was confirmed using.PCR.

此项研究的目的是探讨在直喷式柴油机中,燃油喷射参数对燃烧性能和排放的影响。柴油机的循环情况和燃油喷射参数在发动机燃烧过程和排放中起了重要作用。为了获得喷油参数对柴油机的燃烧性能与排放的影响情况,在带有副燃烧室的单缸直喷式柴油机上进行了试验。试验结果表明,在不同燃油喷射压力和进气气流情况下,副燃烧室能降低排放和改善发动机性能。我们还发现,增加燃油喷射压力可提高气缸压力、气体温度,降低排放。

Water seepag. erosion has been and remains one of the major eng.neering.problems. However, most eng.neers will much depend on borehole data and soil test for desig.ing.and problem detection. By considering.of the cost and destructive method, selection of g.oelectrical prospecting.would be appropriate. Therefore, two electrical g.ophysical surveys were carried out in Sekolah Meneng.h Kebang.aan Dato’ Haji Mohd Nor, g.lug.r, Pulau Pinang.to map the presence of the unknown underg.ound water sources (saturated zones) and its movement. With the total of seven resistivity lines parallel to each other and self potential (SP) with 5 m × 5 m g.idding.survey were successfully done. The resistivity result from line 1 (R1) to line 6 (R6) shows the subsurface consist of saturated zones with rang. between 3 m up to 10 m depth, before it reaches the R7 which is believed as the accumulation zone. Meanwhile, as for SP result it shows the water flow from hig.er value (north-east) towards the lower value which is mostly at the south area. In conclusion, g.oelectrical survey could assist in detecting.and solving.eng.neering.problems as it proven by the result from each method.
