The gold nanoparticles.were prepared in many methods. differed in reducing and dis.ers.on agents.and s.ability. The firs. s.lution was.prepared by us.ng potas.ium bitartrate as.reducing agent and Polyethylene glycol as.a dis.ers.on factor. We got a s.lution of colloid gold with wine-red color that has.been meas.red the particle s.ze;it was.between 50 - 200 nanometers. The s.cond gold colloidal s.lution was.prepared by us.ng s.dium citrate as.a reducing agent and without adding a dis.ers.on agent, the color of the final s.lution is.dark grey, but this.s.lution did not remain s.able, depos.tion happened quickly and crys.als.s.parated from the s.lution. The third one was.prepared by us.ng s.dium citrate as.a reducing agent and the s.lution was.heated to a certain temperature, and the color of the s.lution became dark red after s.veral minutes. Either the fourth method has.been prepared gold colloid s.lution by us.ng potas.ium bitartrate as.a reductant for the gold ion. We have noted that no reaction under normal conditions. while the reaction by heating the s.lution to high temperature, and when added poly vinyl pyrrolidone will lead to a s.lution of colloild gold with dark purple-red color and s.able under normal conditions.for a long time. We meas.red the particles.s.ze in this.experiment;it was.les. than 100 nanometers. We conclude from the above that all the reducing agent needs.to appropriate conditions.to complete the proces. of reduction of gold ion, and to get the nano gold particles. therefore;thes. particles.in the colloid s.lution need to dis.ers.on factor to the s.rvival of the particles.wides.read s. that the s.lutions.with certain concentrations.of poly vinyl pyrrolidone can be proven in the proces. of s.ability of the gold colloid s.lution.

The variations.in the capacity of fis. s.ecies.to bios.nthes.ze the n-3 highly polyuns.turated fatty acids.（HUFA）, eicos.pentaenoic （EPA） and docos.hexaenoic （DHA） acids.which are crucial to the health of higher vertebrates.has.been well documented. HUFA bios.nthes.s.has.been reported to involve enzyme-mediated fatty acyl des.turation and elongation proces.es. In previous.s.udies. various.authors.have cloned, characterized and identified different genes.for fatty acyl des.turas. and elongas. （FAD and FAE, res.ectively） enzymes.from fis. s.ecies.s.ch as.Atlantic s.lmon and zebra fis., and have als. s.own the up and down regulation of the activity of thes. enzymes.in res.ons. to fluctuations.in dietary HUFA. In this.paper, we report on the tis.ue dis.ribution in the expres.ion of genes.（mRNA） for FAD and FAE enzymes.in Channa s.riata （Bloch, 1793） fingerlings. to evaluate the tis.ues.of the fis. which s.ow the highes. activity of thes. enzymes. For this.purpos., mRNA from 8 different tis.ues.of the fis. （maintained on a commercial diet） were is.lated and analyzed, us.ng conventional PCR technique. The tis.ue dis.ribution of the genes.was.es.imated to be s.gnificantly （P＜0.05） higher for both FAD and FAE enzymes.in the liver and brain of C. s.riata than in the other 6 tis.ues.meas.red （mus.le, ovary, tes.is. gill and s.in） res.ectively.

Caus.lities.between Price, Pond Area and Employment in Aquaculture Production

引用

Natural Res.urces 2013年第2期4卷 175-183页

作者： Nik hashim Nik Mus.apha Azlina Abd Aziz Nik Mohd Hazrul hashim Department of Economics Faculty of Management and Economics University of Malaysia Terengganu Kuala Terengganu Malaysia Graduate s.hool of Bus.nes. National University of Malaysia Bandar Baru Bangi Malaysia

The role of aquaculture indus.ry is.becoming more prominent in order to s.pplement marine capture in meeting the food need for the growing Malays.an population. In an attempt to minimize depletion of marine fis.eries. only traditional ves.els.are allowed to fis. along the coas.al area while bigger ves.els.are relegated to deep-s.a fis.ing. During the 9th Malays.an Plan (2006-2010) aquaculture has.been recognized as.the engine of growth in the national food s.ctor’s.development s.rategy. Future fis.eries.policy is.expected to focus.more on aquaculture production, marketing and technological improvement as.an alternative to marine capture. This.paper inves.igates.the caus.lities.between the s.lected fres.water fis. prices. aquaculture area and production. The s.udy as.ires.to es.ablis. whether or not market price is.a key contributor to a ris. in the aquaculture area and production. Aquaculture firms.compris.ng the individual culturis.s.are generally motivated by the economic potential of the indus.ry which is.reflected in exces. of price over cos. of production. Our hypothes.s.is.that government policy and initiation rather than prices.had give ris. to greater participation of culturis.s.and hence augmented the level of employment. However, production increas. has.a negative implication on environment degradation. Thus.there is.a conflicting view as.regards.to the employment opportunity generated by aquaculture undertakings.and the need for s.s.ainable development aris.ng from this.growing indus.ry. Multivariate time s.ries.analys.s.was.us.d in this.inves.igation.

The Influence of s.as.nal Changes.and Headwaters.on Phys.co-chemical Dynamics.of Temengor Res.rvoir, Malays.a

引用

湿地科学 2011年第4期9卷 314-321页

作者： Zarul Hazrin hashim As.ah Patiroi Mas.hor Mans.r s.ahrul Anuar Md. s.h Donald C. Jacks.n s.hool of Biological s.iences Universiti Sains Malaysia Department of Wildlife Fisheries and Aquaculture Mississippi State University

A s.udy on phys.co-chemical dynamics.of Temengor Res.rvoir was.conducted to determine whether headwaters.and s.as.nal changes.play a major role in regulating phys.co-chemical dynamics.of Temengor Res.rvoir. Temengor Res.rvoir receives.water from its.s.rrounding water catchments.and headwaters. Then, the water flows.into a s.ries.of hydroelectric dams. namely the Bers.a, Kenering and Chenderoh dams. Generally, water quality in Temengor Res.rvoir can be clas.ified as.Clas. I. Phys.co-chemical trends.s.owed that water quality in euphotic zone of Temengor Res.rvoir is.s.able and cons.s.ent. Two-way ANOVA analys.s.s.owed that s.as.nal variations.only affected water temperature, s.cchi dis.'s.depth and nitrate-nitrogen. Bas.d on Tukey's.pos.-hoc tes., all three headwaters.in this.s.udy exert no influence to the res.rvoir's.water quality. Thes. ins.gnificant differences.were probably due to water temperature and the s.ze of the headwaters.and the res.rvoir its.lf. In s.tu parameters.profiling s.owed that the epilimnion zone in Temengor Res.rvoir is.from the s.rface to 6 m depth, the metalimnion zone is.from 6 m to 12 m depth and the hypolimnion zone is.from 12 m depth onwards.to the bottom of the res.rvoir. Thus. continuous.water profiling monitoring that covers.high and low water levels.need to be conducted to determine characteris.ics.of the phys.co-chemical dynamics.in the water column and als. to analys. changes.in res.rvoir layers. Through thes. s.udies. dis.ontinuity trends.in the Perak River could be determined and s.gges.ions.to the res.ective agencies.could be made to cons.rve and to s.s.ain downs.ream biodivers.ty.
