    Full Text Available Plecoglossus altivelis (ayu is an amphidromous fish widely distributed in Northeastern Asia from the East China Sea to the northern Japanese coastal waters, encompassing the Korean Peninsula within its range. The shore lines of northeastern region in Asia have severely fluctuated following glaciations in the Quaternary. In the present study, we investigate the population genetic structure and historical demographic change of P. altivelis at a population level in East Asia. Analysis of molecular variance (AMOVA based on 244 mitochondrial control region DNA sequences clearly showed that as the sampling scope extended to a larger geographic area, genetic differentiation began to become significant, particularly among Northeastern populations. A series of hierarchical AMOVA could detect the genetic relationship of three closely located islands between Korea and Japan that might have been tightly connected by the regional Tsushima current. Neutrality and mismatch distribution analyses revealed a strong signature of a recent population expansion of P. altivelis in East Asia, estimated at 126 to 391 thousand years ago during the late Pleistocene. Therefore it suggests that the present population of P. altivelis traces back to its approximate demographic change long before the last glacial maximum. This contrasts our a priori expectation that the most recent glacial event might have the most crucial effect on the present day demography of marine organisms through bottleneck and subsequent increase of effective population size in this region.

    The post-vitellogenic oocytes of teleost fish are generally unresponsive to maturation-inducing hormone (MIH) until a luteinizing hormone (LH) surge stimulates sensitivity via the acquisition of oocyte-maturational competence (OMC). Heterologous gap junctions (GJs) between granulosa cells and the oocyte have been previously implicated in the regulation of oocyte maturation in various vertebrate species. Although heterologous GJ are present in ovarian follicles of ayu (Plecoglossus altivelis), their role in maturation remains unclear. In the present study, we cloned and characterized complementary DNAs for GJ protein connexin (Cx), and examined the expression pattern of Cx messenger RNAs in the ayu ovary. Four Cx cDNAs with predicted molecular masses of 32.1 (Cx32.1), 34.9 (Cx34.9), 44.1 (Cx44.1), and 44.2 (Cx44.2) kDa, respectively, were cloned. Northern blot analysis revealed that the levels of Cx44.1 and Cx44.2 transcripts were similar during the vitellogenic and ovulatory stages. Cx32.1 transcripts were more abundant during the vitellogenic stage, but their levels declined thereafter. Cx34.9 transcript levels increased during the vitellogenic stage and remained high during the acquisition of OMC. In situ hybridization revealed that Cx44.1 and Cx44.2 signals were restricted to the oocyte, whereas the Cx32.1 and Cx34.9 signals were detected in both cellular fractions. Furthermore, a dye-transfer assay revealed the presence of functional GJs between the oocytes and follicle cells. These results suggest that Cx34.9 contributes to the formation of heterologous GJs between oocytes and granulosa cells. Moreover, GJs formed by Cx34.9 may function during the LH-dependent acquisition of OMC and the MIH-dependent resumption of meiosis in ayu. ?? 2007 Wiley-Liss, Inc.

    Ayu (Plecoglossus altivelis) fish, which are an amphidromous species distributed in East Asia, live in brackish water (BW) during their larval stage and in fresh water (FW) during their adult stage. In this study, we found that FW-acclimated ayu larvae exhibited a slower growth ratio compared with that of BW-acclimated larvae. However, the mechanism underlying FW acclimation on growth suppression is poorly known. We employed transcriptome analysis to investigate the differential gene expression of FW acclimation by RNA sequencing. We identified 158 upregulated and 139 downregulated transcripts in FW-acclimated ayu larvae compared with that in BW-acclimated larvae. As determined by Gene Ontology annotation and Kyoto Encyclopedia of Genes and Genomes pathway mapping, functional annotation of the genes covered diverse biological functions and processes, and included neuroendocrinology, osmotic regulation, energy metabolism, and the cytoskeleton. Transcriptional expression of several differentially expressed genes in response to FW acclimation was further confirmed by real-time quantitative PCR. In accordance with transcriptome analysis, iodothyronine deiodinase (ID), pro-opiomelanocortin (POMC), betaine-homocysteine S-methyltransferase 1(BHMT), fructose-bisphosphate aldolase B (aldolase B), tyrosine aminotransferase (TAT), and Na(+)-K(+) ATPase (NKA) were upregulated after FW acclimation. Furthermore, the mRNA expressions of b-type natriuretic peptide (BNP) and transgelin were downregulated after FW acclimation. Our data indicate that FW acclimation reduced the growth rate of ayu larvae, which might result from the expression alteration of genes related to endocrine hormones, energy metabolism, and direct osmoregulation.

    Meiotic resumption in teleost oocytes is induced by a maturation-inducing hormone (MIH). The sensitivity of oocytes to MIH, also known as oocyte maturational competence (OMC), is induced by LH via mechanisms that are not fully understood. A previous study of Ayu (Plecoglossus altivelis) showed the presence of functional heterologous gap junctions (GJs) between oocytes and their surrounding granulosa cells. The objectives of this study were to determine the role of ovarian GJs and of protein kinase A (PKA) during the acquisition of OMC. We examined the effects of the specific GJ inhibitor carbenoxolone (CBX) and 18??-glycyrrhetinic acid (??-GA) on the LH-(hCG)-dependent acquisition of OMC and on MIH-(17,20??-dihydroxy-4-pregnen-3-one)-dependent meiotic resumption; measured the cAMP content of ovarian follicles during the hCG-dependent acquisition of OMC; and determined the effects of PK activators and inhibitors on hCG-dependent OMC. Production of follicular cAMP increased during the hCG-dependent acquisition of OMC. Both GJ inhibitors and the PKA inhibitor H8-dihydrochloride, but not the PKC inhibitor GF109203X, suppressed the hCG-dependent acquisition of OMC in a dose-dependent manner. The PKA activator forskolin induced OMC with a similar potency to hCG. Unlike previous observations with teleosts where disruption of heterologous GJ either blocks or stimulates meiotic resumption, treatment with GJ inhibitors did not affect MIH-dependent meiotic resumption in maturationally competent follicles of Ayu. These observations suggest that ovarian GJs are essential for LH-dependent acquisition of OMC but not for MIH-dependent meiotic resumption, and that the stimulation of OMC by LH is mediated by cAMP-dependent PKA. They are also consistent with the view that a precise balance between GJ-mediated signals (positive or negative) and oocyte maturational readiness is required for hormonally regulated meiotic resumption. ?? 2007 Elsevier Inc.

    This study spatially analyzed potential carcinogenic risks associated with ingesting arsenic (As) contents in aquacultural smeltfish (Plecoglossus altirelis) from the Lanyang Plain of northeastern Taiwan. Sequential indicator simulation (SIS) was adopted to reproduce As exposure distributions in groundwater based on their three-dimensional variability. A target cancer risk (TR) associated with ingesting As in aquacultural smeltfish was employed to evaluate the potential risk to human health. The probabilistic risk assessment determined by Monte Carlo simulation and SIS is used to propagate properly the uncertainty of parameters. Safe and hazardous aquacultural regions were mapped to elucidate the safety of groundwater use. The TRs determined from the risks at the 95th percentiles exceed one millionth, indicating that ingesting smeltfish that are farmed in the highly As-affected regions represents a potential cancer threat to human health. The 95th percentile of TRs is considered in formulating a strategy for the aquacultural use of groundwater in the preliminary stage

    A high lateral resolution secondary ion mass spectrometer (NanoSIMS NS50 ion microprobe) has been used to measure {sup 87}Sr/{sup 86}Sr ratios in natural CaCO{sub 3} samples. A {approx}2 nA O{sup -} primary beam was used to sputter a 5-7-{mu}m diameter crater on the sample surface and secondary positive ions were extracted for mass analysis using an accelerating voltage of 8 kV and a Mattauch-Herzog geometry. The multi-collector system was adjusted to detect {sup 43}Ca{sup +} (by a detector EM2), {sup 80}Ca{sub 2}{sup +} (EM3), {sup 86}Sr{sup +} (EM4), and {sup 87}Sr{sup +} (EM4b) ions at the same time. Then the magnetic field was scanned for the EM4 to detect {sup 85}Rb{sup +}, {sup 86}Sr{sup +} and {sup 87}Sr{sup +}, while the EM4b can measure {sup 86}Sr{sup +}, {sup 87}Sr{sup +} and {sup 88}Sr{sup +}, respectively. A mass resolution of 3600 at 10% peak height was attained with a flat peak top, while the sensitivity of Sr was about 10 cps/nA/ppm. An aragonite sample (coral skeleton standard; JCp-1) was used as a reference for Sr isotope ratio calibration. Repeated analyses of the JCp-1 show that the {sup 87}Sr/{sup 86}Sr ratio agrees well with the seawater signature within a precision of 0.3 per mille at 2{sigma}, after the series of corrections such as the Ca dimer, {sup 87}Rb, and a mass bias estimated by the {sup 88}Sr/{sup 86}Sr ratio. The method was applied to an otolith (ear-stone) from ayu (Plecoglossus altivelis altivelis) collected from the Yodo river, Japan. Although experimental errors are relatively large, up to 3 per mille at 2{sigma}, the ratios of the core region are higher than the seawater signature while more distal values agree well with seawater. The very outermost part again shows the relatively higher {sup 87}Sr/{sup 86}Sr ratios. The spatial variation of {sup 87}Sr/{sup 86}Sr ratios was consistent with amphidromous migration of the fish, namely, born in the lake and grown in the coastal sea and finally collected in a river.

    The word Ayurveda comes from the Sanskrit root Ayu which means span of life. The purpose of examination of Ayu is to obtain knowledge regarding longevity, residual span of life in diseased person and rate of the mortality. The purpose of Dashavidha Pariksha is to obtain knowledge regarding Dosha Bala (Vyadhi Bala), Bala (Rogibala) and Ayu of the patient as described in Charak Samhita . Commonly Ayu and Vaya are regarded as synonyms but they are not similar terms. Hence, description of Vaya and Ayu is separately mentioned in Charaka as well as Sushruta Samhita . Description exclusively on Ayu Pareeksha described in Charaka Viman Sthana, Charaka Chikitsasthana, Charaka Indriya Sthana and Charaka Shareer Sthana. In Indriya Sthana, Ayu Pariksha indicates the residual life-span of the diseased person and where as in Jaatisutriya Adhyaya in Shareer Sthana mentioned the characteristic properties of the child who is going to survive for longer period of time. In Sushruta Samhita, Ayu is classified into three broad headings namely Dhirghayu, Madhyamayu and Alpayu and explained the characteristic properties of all the three.

Sebelum berkembangnya kerapu hibrid, Balai Besar Penelitian dan Pengembangan Budidaya Laut Gondol, sudah berhasil mengembangkan pembenihan ikan kerapu bebek meskipun sintasan yang diperoleh masih bervariasi. Pemantauan benih hasil budidaya sebagian besar terfokus pada pertumbuhan dan jika sudah mencapai ukuran konsumsi bisa dijual atau diekspor ke Hongkong. Sebagai institusi penelitian nampaknya masih perlu mengupas lebih detail komoditas yang dikembangkan. Beberapa catatan yang dapat diperhatikan, untuk lebih mengenal komoditas kerapu bebek, sebelum dijadikan sebagai ikon jenis ikan yang pernah memiliki masa kejayaan, karena saat ini popularitasnya relatif menurun karena ada larangan ekspor dan masuk dalam satwa CITES. Catatan tersebut antara lain; kerapu bebek selama fase yuwana (2-3 bulan dapat dijadikan sebagai kandidat ikan hias dengan performasi bintik bintik hitam pada permukaan tubuh yang merupakan keunikan tersendiri, karena jumlah dan polanya berbeda antara satu individu dengan yang lainnya serta akan bertambah jumlahnya seiring dengan bertambahnya umur dan bobot badan.

    Reliable indicators on whether natural and cultured fish exhibit differences in habitat preferences are lacking. In this study, δ 13 C and δ 15 N were used to distinguish the habitat preferences of cultured versus natural ayu and their prey (periphyton) in a typical riffle-pool river reach. It found that the δ 13 C of natural ayu (-13.747‰) was consistent with that of periphyton in riffles (-14.611‰), while the δ 13 C of cultured ayu (-19.088‰) was consistent with that of periphyton (-19.711‰) in pools. The results indicated that cultured ayu appear to favor pools whereas natural ayu favor riffles, and δ 13 C and δ 15 N represent potential reliable indicators of habitat preferences of cultured ayu.

    Full Text Available Pembenihan ikan kerapu dihadapkan pada rendahnya sintasan, terutama fase awal hidupnya. Rendahnya sintasan diduga berhubungan dengan belum berkembangnya organ pencernaan larva dan tidak tersedianya pakan yang siap diserap tubuh. Pemberian asam amino bebas seperti taurin dan glutamin melalui rotifer diharapkan dapat meningkatan ketersediaan nutrien yang dapat diserap dengan cepat oleh larva, sehingga sintasan larva tinggi dan dapat tumbuh lebih cepat. Penelitian bertujuan mengukur pengaruh glutamin atau taurin terhadap sintasan dan pertumbuhan larva kerapu bebek Cromileptes altivelis. Larva umur 1 hari (10 ekor.L-1 dipelihara dalam bak fiberglass volume 500 L yang diisi air laut sampai 330 L. Larva diberi pakan rotifer diperkaya 0,5 g glutamin, 0,5 g taurin, atau tanpa glutamin dan taurin. Larva dipelihara selama 16 hari dengan pemberian pakan 2 kali  per hari. Satu jam setelah pemberian pakan dilakukan pengamatan terhadap jumlah rotifer dalam saluran pencernaan larva ikan. Hasil penelitian menunjukkan jumlah rotifer dalam saluran pencernaan larva meningkat seiring dengan bertambahnya umur. Namun, jumlah rata-rata rotifer yang dikonsumsi larva pada perlakuan 0,5 g glutamin atau 0,5 g taurin lebih banyak dibanding perlakuan tanpa taurin dan glutamin. Larva yang diberi rotifer hasil pengkayaan dengan 0,5 g glutamin atau 0,5 g taurin memiliki sintasan yang tidak berbeda (P>0,05, masing-masing 19,2±2,25%, dan 24,5±1,20%, dan secara signifikan lebih banyak dibanding larva di perlakuan tanpa glutamin dan taurin yang nilainya 13,0±1,70%. Larva yang diberi rotifer hasil pengkayaan dengan 0,5 g taurin secara signifikan lebih panjang (5,5±0,18 mm dari ikan di perlakuan 0,5 g glutamin (5,3±0,12 mm. Demikian juga, larva di perlakuan glutamin lebih panjang dari pelakuan tanpa glutamin dan taurin (5,0±0,16 mm. Pengkayaan rotifer menggunakan asam amino bebas taurin atau glutamin dapat meningkatkan sintasan dan pertumbuhan larva kerapu bebek. Namun

    The process used to form and operate the Selendang Ayu Fisheries Work Group was discussed. The M/V Selendang Ayu ran aground and broke apart near Unalaska Island, Alaska in December 2004, causing immediate concern to nearby commercial fisheries and seafood processors. The work group, which was formed less than 2 weeks after the initial spill, was modeled after other Alaska work groups and consisted of experts in environmental health, fisheries biology and oceanography. Its task was to facilitate communication between fishery managers and spill responders to identify risk-reducing measures and to minimize impacts to fisheries in Alaska. In support of Alaska's zero tolerance policy toward any contamination of food processed in Alaska, the working group conducted water quality sampling in and around Unalaska Island from December 2004 though March 2005. Information was gathered regarding fishery opening and closing dates, geographic extent of fisheries, gear and vessel types, seawater circulation systems, fish processing operations, vessel transit routes and other considerations related to the potential exposure of vessels, gear or seafood to oil. This paper described the different pathways that commercial fish species may be exposed to spilled oil, along with the major fish species at risk. One small fishery closure was enacted. The working group was successful in ensuring that major commercial fisheries for snow crab, pollock, halibut and other species were successfully conducted during the spill, with all loads undergoing mandatory seafood inspections. Seafood products were not contaminated and market prices remained stable. 15 refs., 6 tabs., 4 figs

    Full Text Available Tulisan ini bertujuan mendeskripsikan posisi tokoh­tokoh perempuan dalam dua novel karya pengarang Bali-Tempurung dan Ayu Manda dengan pendekatan feminis. Tempurung karya perempuan pengarang, Oka Rusmini, dan Ayu Manda garapan I Made Iwan Darmawan. Kedua novel tersebut sama­sama diterbitkan pada tahun 2010. Kedua novel tersebut dipilih karena sangat kental menyajikan beragam persoalan perempuan. Eksploitasi gender sebagai sebuah konstruk sosial budaya, mengakibatkan timbulnya ketidakadilan­ketidakadilan. Ironisnya, ketidakadilan tersebut mengalami pembiaran akibat ketatnya hegemoni adat dan tatanan dalam masyarakat. Masalah tersebut dimunculkan secara padat dan cepat dalam novel Tempurung dan Ayu Manda. Novel Tempurung menampilkan gambaran perempuan­perempuan yang dihegemoni oleh budaya dan masyarakatnya. Pada novel Ayu Manda yang mengambil latar waktu 1960­an, geliat penolakan terhadap ketidakadilan mulai ditampilkan. Akan tetapi, ketika perempuan mulai berbicara tentang dan terlibat cinta, perempuan akan berhadapan dengan kuasa adat istiadat dan tradisi yang siap memarginalkan tubuhnya jika tidak bersepaham dengannya. Temuan yang didapat dari hasil penelitian ini adalah perempuan­perempuan dalam kedua novel tersebut diposisikan sebagai manusia yang berjenis kelamin berbeda sehingga harus diperlakukan berbeda pula. Abstract: This article aims to describe the position of female characters in two novels written by Balinese writers, Tempurung and Ayu Manda, using feminist approach. Tempurung was written by a female writer, Oka Rusmini, whereas Ayu Manda is a work of I Made Iwan Darmawan. Both novels were published in 2010. The two novels were chosen for strongly presenting various woman issues. Gender exploitation as a sociocultural construction brings about discriminations. Ironically, ironically, those discriminations have been allowed because of a firm hegemony of tradition and social order of society. The issue is solidly and fast

    Ayu Plecoglossus altivelis, a herbivorous fish, is an important fishery resource and key component of the foodweb in many Japanese streams. Radionuclide contamination of this species is likely transferred to higher trophic levels, include humans, in the food chain. After the Fukushima accident in March 2011, ayu were exposed to highly contaminated silt while feeding on algae attached to the riverbed stones. To understand the route by which herbivorous fish are exposed to radionuclides, the activity concentrations of sum of 134 Cs and 137 Cs (radiocesium) were analyzed in riverbed samples (algae and silt) and in the internal organs and the muscle of ayu in five river systems in the Fukushima Prefecture between summer 2011 and autumn 2013. Although there was a positive correlation between the radiocesium activity concentrations in the muscle and the internal organs of ayu, the median activity concentration in the muscle was much lower than those in the internal organs. The activity concentrations of radiocesium in the riverbed samples and the internal organs and the muscle of ayu were correlated with contamination levels in soil samples taken from the watershed upstream of the sample sites. The results of the generalized linear mixed models suggest that the activity concentrations in both the internal organs and the muscle of ayu declined over time. Additionally, the activity concentrations in the internal organs were correlated with those in the riverbed samples that were collected around the same time as the ayu. The activity concentrations in the muscle were correlated with ayu body size. Our results suggest that ayu ingest 134 Cs and 137 Cs while grazing silt and algae from the riverbed, and a part of the 134 Cs and 137 Cs is assimilated into the muscle of the fish. - Highlights: • The radiocesium (sum of 134 Cs and 137 Cs) concentrations in a herbivorous fish were measured following the Fukushima disaster. • The muscle concentrations were correlated with

    Full Text Available In eight novels, Ayu Utami has presented critical attacks on doctrines and practices of the major religions in Indonesia. The two books, that describe the spiritual struggle of the Catholic priest Saman (1998–2002, call for a religion that is more active in the political arena, but leaves sexual rules to the individual people. The novel Bilangan Fu (2008 condemns the monopoly of the great religions in favour of local and individual spirituality. This is developed in a series of novels of which two more have already appeared. A third cycle of three more or less autobiographic novels (2003–2013 sketch her personal quest from atheism towards a critical but positive spirituality condemning a clerical and monopolist trend in Catholicism. Utami’s criticism of the great religions is external (more players in the field should be recognised and internal (religious leaders should have more modest claims towards their faithful and leave more space for personal choice.

    Promoter as gene expression regulator is one of the factors affecting the successful of transgenesis. Isolation and characterization of β -actin promoter (ktBA from humpback grouper (Cromileptes altivelis towards generation of autotransgenic grouper have been conducted.  β -actin promoter has high activity in muscle. Sequence of ktBA promoter was isolated by using degenerate PCR method. Sequencing was performed using ABI PRISM 3100 machine. Analysis of sequences was conducted using BLAST, GENETYX version 7 and TFBind softwares. DNA fragment of PCR amplification product digested from the vector cloning was then ligated with pEGFPN1 to generate pktBA-GFP construct. The construct was microinjected into one-cell stage of zebrafish (Danio rerio embryos to test the ktBA promoter activity. EGFP gene expression was observed by fluorescence microscope. The result of sequence analysis showed that the length of DNA fragment obtained is about 1.6 kb and containing the evolutionary conserved sequences of transcription factor for β -actin promoter including CCAAT, CArG and TATA boxes. Furthermore, ktBA sequence in pktBA-EGFP construct could drove GFP expression in muscle of zebrafish embryos injected with the construct. The results suggested that PCR amplification product is the regulator sequence of humpback grouper β -actin gene. Autotransgenic grouper can be then produced by changing GFP gene fragment of pktBA-EGFP construct with genes from grouper encoding important traits in aquaculture.

    Full Text Available Infection of grouper sleepy disease iridovirus (GSDIV which is a member of Megalocytivirus causes mass mortalities in marine fish in Indonesia. This study was conducted to know the effectiveness of recombinant subunit vaccine of GSDIV with an addition of adjuvants against GSDIV infection. Inactive bacteria Eschericia coli containing recombinant MCP-GSDIV protein was added with montanide ISA adjuvant at a ratio of 3:7. The vaccine was administered to humpback grouper, Cromileptes altivelis by intramuscular and intraperitoneal injection at a dose of 0.1 mL/fish. Test of the vaccine in humpback grouper was performed in four replicates (four trials. Results of the vaccination showed that the recombinant protein vaccine added with the adjuvant increased immunity of humpback grouper, indicated by higher relative percent survival (RPS= 77.78% compared to negative control (PBS and 50% higher compared to protein control (pET Sumo CAT at two weeks post vaccination. The RPS values of the recombinant protein vaccine were still higher (53.57%-72.73% than those of the control vaccine and 25%-53.33% of the protein control in the 4th week post vaccination. GSDIV detection by PCR showed that MCP-GSDIV-DNA and pET Sumo CAT-DNA were not detected in the vaccinated fish after one, two, three, and four weeks post vaccination. The fish died in both of vaccinated and control groups after experimental challenge with GSDIV were found to be infected with GSDIV. It can be stated that recombinant subunit vaccine of GSDIV with the addition of montanide ISA adjuvant could be used to prevent and diminish mortalities of grouper against GSDIV infection.

    Full Text Available The Indo-pacific panther grouper (Chromileptes altiveli is a predatory fish species and popular imported aquarium fish in the United States which has been recently documented residing in western Atlantic waters. To date, the most successful marine invasive species in the Atlantic is the lionfish (Pterois volitans/miles, which, as for the panther grouper, is assumed to have been introduced to the wild through aquarium releases. However, unlike lionfish, the panther grouper is not yet thought to have an established breeding population in the Atlantic. Using a proven modeling technique developed to track the lionfish invasion, presented is the first known estimation of the potential spread of panther grouper in the Atlantic. The employed cellular automaton-based computer model examines the life history of the subject species including fecundity, mortality, and reproductive potential and combines this with habitat preferences and physical oceanic parameters to forecast the distribution and periodicity of spread of this potential new invasive species. Simulations were examined for origination points within one degree of capture locations of panther grouper from the United States Geological Survey Nonindigenous Aquatic Species Database to eliminate introduction location bias, and two detailed case studies were scrutinized. The model indicates three primary locations where settlement is likely given the inputs and limits of the model; Jupiter Florida/Vero Beach, the Cape Hatteras Tropical Limit/Myrtle Beach South Carolina, and Florida Keys/Ten Thousand Islands locations. Of these locations, Jupiter Florida/Vero Beach has the highest settlement rate in the model and is indicated as the area in which the panther grouper is most likely to become established. This insight is valuable if attempts are to be made to halt this potential marine invasive species.

    The method of Pb and Sr isotope measurements at about 5 μm resolution was developed by using a high lateral resolution secondary ion mass spectrometer (NanoSIMS NS50). Since the both elements have radiogenic nuclides such as 206 Pb, 207 Pb, and 87 Sr, natural variations of isotopic ratios are large. It is possible to detect a meaningful variation in a terrestrial sample, even though the experimental error is relatively large. In the case of monazite U-Pb dating, a 4 nA O - primary beam was used to sputter the sample and secondary positive ions were extracted for mass analysis using a Mattauch-Herzog geometry. The multi-collector system was modified to detect 140 Ce + , 204 Pb + , 206 Pb + , 238 U 16 O + , and 238 U 16 O 2 + ions simultaneously. Based on the monazite standard from North-Central Madagascar, we have determined the 206 Pb/ 238 U ratios of samples. 207 Pb/ 206 Pb ratios were measured by a magnet scanning with a single collector mode. 44 monazite grains extracted from a sedimentary rock in Taiwan were analyzed. Observed ages were consistent with the U-Th-Pb chemical ages by EPMA. Then NanoSIMS has been used to measure 87 Sr/ 86 Sr ratios in natural calcium carbonate samples. Multi-collector system was adjusted to detect 43 Ca + , 80 Ca 2 + , 86 Sr + , and 87 Sr + ions at the same time. Magnetic field was scanning for the EM no.4 counter to detect 85 Rb + , 86 Sr + and 87 Sr + , while the EM no.4b can measure 86 Sr + , 87 Sr + , and 88 Sr + , respectively. Repeated analyses of a coral skeleton standard (JCp-1) show that 87 Sr/ 86 Sr ratio agrees well with the seawater signature, after the series of corrections such as Ca dimer, 87 Rb, and a mass bias estimated by 88 Sr/ 86 Sr ratio. The method is applied to an otolith from ayu (Pleco-glossus altivelis altivelis) collected from the Yodo river, Japan. The spatial variation of 87 Sr/ 86 Sr ratios was consistent with amphidromous migration of the fish, namely, born in the lake and grown in the coastal sea

    Full Text Available Feeding experiments were conducted to evaluate the effects of replacing fishmeal with soybean meal in diet on growth of humpback grouper. Fifteen cages of 1 x 1 x 1.2 m3 each stocked with 16 humpback grouper juveniles (61.3 ± 0.4 g/pc were set up randomly in seawater. Fish were fed to satiation twice daily for 112 days. The control diet contained 61.9% fishmeal (63.34% crude protein. Four isonitrogenous (48% crude protein and isocaloric (4.7 kcal/g feed diets supplemented with commercial phytase “Rhonozyme-P” at 0.075% were formulated to contain different levels (8%, 16%, 24%, and 32% soybean meal (43.65% crude protein as a partial replacement for fishmeal. These diets contained total phosphorus levels between 3.6—4.5 (±0.4 % and 0.7—1.5 (±0.04 % available phosphorus. Replacement of fishmeal with soybean meal (8 to 32% replacement was not significantly different (P>0.05 to the control diet on daily growth rate (DGR, food conversion ratio (FCR, protein efficiency ratio (PER, and daily food consumption (DFC. However, the dietary levels of soybean meal significantly affected (P<0.05 whole body protein and phosphorus retention (Table 1. These data suggest that addition of phytase in diets could improve protein and phosphorus availability and reduce nitrogen and phosphorus loading in the environment. Phytase can therefore play an important role in formulating eco-friendly feed for humpback grouper. Based on P loading, supplementation of phytase enable up to 24% fishmeal replacement with soybean meal.

    Full Text Available Pathognomonic sign of grouper sleepy disease iridovirus (GSDIV was proposed to be the formation of enlarged cells and necrotic cells, in which under electron microscope, it is revealed to be the inclusion body bearing cells (IBCs and necrotic cells containing GSDIV viral particles. Spleen and kidney tissues are the major sites for formation of enlarged cells. This paper described the result of histopatological analysis of enlarged cells found in the spleen and kidney of moribund fish after GSDIV challenge. A pathogenicity test was conducted on fish stocked in two tanks for infected groups and the other two tanks for uninfected control groups (15 fish per tank. The infected groups were injected intramuscularly with 0.1 ml of the viral inoculum. The uninfected groups were injected with the same amount of EMEM-2. The GSDIV-infected humpback grouper began to die after 6 days post infection and all died after 7 dpi, excluding one fish which had survived until the end of experimental infection periods (93% to 100% mortality. All of the diseased fish showed massive formation of enlarged cells in their spleen, head kidney and trunk kidney. The largest number of enlarged cells was observed on head kidneys and subsequently followed by spleens, trunk kidney (2.0-200.3/field of view. This result suggested that the number of enlarged cells in the affected organs was not the direct factor that led to the mortality of fish.

    Radionuclide ((131)I, (134)Cs, and (137)Cs) concentrations of monitored freshwater fish species collected from different habitats (rivers, lakes, and culture ponds) in Fukushima Prefecture during March 2011-December 2014 (total 16 species, n = 2692) were analyzed to present a detailed description of radionuclide contamination after the Fukushima Dai-ichi Nuclear Power Plant (FDNPP) accident, and to elucidate species-specific spatiotemporal declining trends of (137)Cs concentration for their respective habitats. Low concentrations of (131)I (≤24 Bq kg(-1)-wet) were detected from only 11 samples collected during March-June 2011, demonstrating that (131)I transferred to freshwater fish were not intense. In river and lake fishes, a more gradual decrease and higher radiocesium ((134)Cs, (137)Cs) concentrations were observed than in culture pond fishes, which strongly implied that radiocesium in freshwater fish species was mainly bioaccumulated through the food web in the wild. During 2011-2014, percentages above the Japanese regulatory limit of 100 Bq kg(-1)-wet for radiocesium in river and lake fish (14.0% and 39.6%, respectively) were higher than in monitored marine fish (9.9%), indicating longer-term contamination of freshwater fish species, especially in lakes. Higher radiocesium concentrations (maximum 18.7 kBq kg(-1)-wet in Oncorhynchus masou) were found in the northwestern areas from the FDNPP with higher deposition. However, radiocesium contamination levels were regarded as 1-2 orders of magnitude less than those after the Chernobyl accident. Lagged increase of (137)Cs concentration and longer ecological half-lives (Teco: 1.2-2.6 y in the central part of Fukushima Prefecture) were observed in carnivorous salmonids (O. masou, Salvelinus leucomaenis), whereas a rapid increase and decrease of (137)Cs concentration and shorter Teco (0.99 and 0.69 y) were found in herbivorous and planktivorous osmerids (Plecoglossus altivelis, Hypomesus nipponensis) with

    Importin β1 (Impβ)/karyopherin β1 (Kpnb1) mediates the nuclear import of a large variety of substrates. This study aimed to investigate the requirement for the Kpnb1 gene in mouse development, using a gene trap line, B6-CB-Ayu8108 GtgeoIMEG (Ayu8108 geo ), in which the trap vector was inserted into the promoter region of the Kpnb1 gene, but in reverse orientation of the Kpnb1 gene. Ayu8108 geo/geo homozygous embryos could develop to the blastocyst stage, but died before embryonic day 5.5, and expression of the Kpnb1 gene in homozygous blastocysts was undetectable. We also replaced the βgeo gene with Impβ cDNA through Cre-mediated recombination to rescue Impβ expression. Homozygous mice for the rescued allele Ayu8108 Impβ/Impβ were born and developed normally. These results demonstrated that the cause of post-implantation lethality of Ayu8108 geo/geo homozygous embryos was impaired expression of the Kpnb1 gene, indicating indispensable roles of Impβ1 in early development of mice

    Pituitary extracts and plasmas of 35 species of fish were tested in two radioimmunoassay (RIA) systems, a salmon-salmon homologous RIA and a salmon-carp heterologous RIA, in which the same antiserum, raised against salmon gonadotrophin, SG-G100, was employed. In the homologous RIA, most salmonid species tested, except for the powan and ayu, cross-reacted in a manner identical with that of the standard, SG-DEAE-3. Nonparallelism of inhibition curves were found in 13 non- salmonid species while 3 others showed non cross-reaction. In the heterologous RIA, all cyprinids, except the rudd, and all salmonids, except the ayu, as well as 9 other species, gave inhibition curves parallel to that of the standard purified carp gonadotrophin. These results may indicate that immunological properties of fish gonadotrophins do not correspond to known phylogenetic relationships of fishes

    Mechanical alloying (MA) of Al-Ti alloy, being a solid state process, offers the unique advantage of producing homogeneous and fine dispersions of thermally stable Al 3 Ti phase, where the formation of the fine Al 3 Ti phase by the other method is restricted from the thermodynamic viewpoint. The MA Al-Ti alloys show substantially higher strength than the conventional Al alloys at the elevated temperature due to the presence of Al 3 Ti as well as Al 4 C 3 and Al 2 O 3 , of which the last two phases were introduced during MA process. The addition of V or Zr to Al-Ti alloy was known to decrease the lattice mismatch between the intermetallic compound and the aluminum matrix, and such decrease in lattice mismatching can influence positively the high temperature mechanical strength of the MA Al-Ti by increasing the resistance to dispersoid coarsening at the elevated temperature. In the present study, therefore, the mechanical behavior of the MA Al-Ti-V and Al-Ti-Zr alloys were investigated in order to evaluate the effect of V or Zr addition on the mechanical properties of the MA Al-8Ti alloy at high temperature

    Full Text Available Basil is a popular medicinal and culinary herb, and its essential oils have been used extensively for many years in food products, perfumery, dental and oral products. Basil essential oils and their principal constituents were found to exhibit antimicrobial activity against a wide range of Gram-negative and Gram-positive bacteria, yeast, and mould. The essential oils obtained from aerial parts of three different species of Ocimum comprising twenty one germplasm lines were investigated for their essential oil composition and antimicrobial activity during 2010. Essential oils from seventeen germplasm lines in Ocimum basilicum and two each in Ocimum tenuiflorum and Ocimum gratissimum were investigated for anti-microbial activity against four bacterial strains (Staphylococcus aureus, Bacillus sps., Escherichia coli and Pseudomonas aeruginosa. The morpho-chemotypes exhibited wide variability for morphological and chemical traits. Anti-bacterial activity was found to be high for Staphylococcus aureus, moderate for Escherichia coli, low for Bacillus and Pseudomonas aeruginosa was highly resistant. The essential oils of Pale Green-Broad Leaves (O. basilicum and CIM Ayu (O. gratissimum exhibited significant antibacterial activity against both S. aureus and E. coli signifying them promising for anti-bacterial activity. No relationship was observed between chemotype specificity and anti-bacterial activity, indicating that apart from major components of essential oil, minor components and other factors may be responsible for anti-microbial activities.

    Full Text Available This research is motivated by colonial problems in the archipelago that still leave traces of oppression as well as efforts of the struggle of the natives to escape from the impact of the ideology. The trail of colonial colonization that still lags behind creates indigenous groups that become subalterns-isolated, oppressed, and discarded groups. In the postcolonial theory of subaltern Gayatri Spivax it is stated that among the most victimized groups of colonialism are women. Relevant to the issue, this study aims to describe the forms of oppression and the struggle of indigenous people, especially women who become subalterns, against the colonial ideology. Data obtained from modern Indonesian novels are then analyzed qualitatively. Based on the research data source, Orang-orang Blanti by Wisran Hadi, Maya by Ayu Utami and Gadis Pantai by Pramoedya Ananta Toer, the result of this research shows that indigenous figures, especially women become subaltern because they are marginalized, economically impoverished, labeled, As well as experiencing sexual harassment. Furthermore the form of the struggle of indigenous women in the face of colonial oppression in the context of the subaltern is to foster the spirit of struggle by recalling the glory of the past, practicing the knowledge gained through modern education, maintaining traditional and cultural values, as well as mimicry Keywords: novel, women, postcolonial, indigenous, subaltern

    Full Text Available Mereka Bilang Saya Monyet, a movie by woman director Djenar Maesa Ayu, was a film about women with a different perspective. This movie reveals a discourse on both violence and women’s resistance against it. The dimensions shown included psychological, physical, and sexual violence between parents and their child, an adult men with his daughter, and adult men with adult women. Violence appears because of the unbalanced relationship between subject and object. The effects of this violence can take the form of fear, anger, or a feeling of inferiority and unworthiness, and the victim feels encouraged to act on it. Discourse related to gender-based violence is a result of a patriarchal cultural construction. In the film, resistance was portrayed through the victim’s suffering, anger, and physical resistance. Women directors perceived these issues from a different perspective. It is not enough to understand violence against women only from the normative perspective of law and social obligation. This issue must be understood by positioning women as the subject (survivor and recognizing that violence against women is a crime against humanity.

  14. Spilled Oils: Static Mixtures or Dynamic Weathering and Bioavailability?

    Full Text Available Polynuclear aromatic hydrocarbons (PAHs from sequestered MV Selendang Ayu oil were biologically available in 2008, 3.6 y after it was spilled along Unalaska Island, Alaska. Thermodynamically driven weathering was the most probable mechanism of organism exposure to PAHs. Alkane and PAH composition in oil changed over time as smaller constituents were preferentially lost, indicative of weathering. In contrast, composition of the largest compounds (biomarkers including triterpanes, hopanes, and steranes remained unchanged. Smaller molecules (the PAHs lost from stranded oil were observed in indigenous mussels and passive samplers deployed in July 2008. Concentration and composition of PAHs were significantly different than in a non-oiled reference area and patterns observed in mussels were repeated in passive samplers deployed in three zones (intertidal, subtidal, and water. Thus, hydrocarbons lost from one compartment (sequestered whole oil were detectable in another (mussels and passive samplers implying aqueous transfer. Quantities of mobile oil constituents were small, yielding uptake concentrations that are likely inconsequential for mussels, but the sensitivity provided by bioaccumulation and passive sampler uptake ensured that dissolved hydrocarbons were detectable.

  15. Sex change strategy and the aromatase genes.

    Sequential hermaphroditism is a common reproductive strategy in many teleosts. Steroid production is known to mediate both the natural and induced sex change, yet beyond this the physiology directing this process has received little attention. Cytochrome P450 aromatase is a key enzyme in the hormonal pathway catalysing the conversion of sex steroids, androgens to oestrogens, and thus is highly relevant to the process of sex change. This study reports the isolation of cDNA sequences for aromatase isoforms CYP19A1 and CYP19A2 from teleost species representing three forms of sexual hermaphroditism: Lates calcarifer (protandry), Cromileptes altivelis (protogyny), and Gobiodon histrio (bi-directional). Deduced amino acid analysis of these isoforms with other reported isoforms from gonochoristic (single sex) teleosts revealed 56-95% identity within the same isoform while only 48-65% identity between isoforms irrespective of species and sexual strategy. Phylogenetic analysis supported this result separating sequences into isoform exclusive clades in spite of species apparent evolutionary distance. Furthermore, this study isolates 5' flanking regions of all above genes and describes putative cis-acting elements therein. Elements identified include steroidogenic factor 1 binding site (SF-1), oestrogen response element (ERE), progesterone response element (PRE), androgen response element (ARE), glucocorticoid response elements (GRE), peroxisome proliferator-activated receptor alpha/retinoid X receptor alpha heterodimer responsive element (PPARalpha/RXRalpha), nuclear factor kappabeta (NF-kappabeta), SOX 5, SOX 9, and Wilms tumor suppressor (WTI). A hypothetical in vivo model was constructed for both isoforms highlighting potential roles of these putative cis-acting elements with reference to normal function and sexual hermaphroditism.

    Full Text Available Immer mehr indonesische Autorinnen haben insbesondere seit dem Sturz Präsident Suhartos die literarische Bühne erobert. Viele ihrer Bücher wurden Bestseller, mit bis zu 100.000 verkauften Kopien. Diese zunehmende Popularität hängt vor allem mit Tendenzen der Liberalisierung, Aufhebung der Zensur und einer Redefinition der Rolle der Frau zusammen. Einige Schriftstellerinnen machten in der letzten Dekade durch die offene Thematisierung von Sexualität und Begehren der Frau auf sich aufmerksam, ein Tabuthema, das während der Neuen Ordnung nicht in dieser Weise hätte diskutiert werden können. Die meisten dieser Autorinnen, deren Literatur in den Medien oftmals mit dem umstrittenen Begriff sastrawangi (Duftliteratur bezeichnet wird, wählen als Handlungsschauplätze ihrer Erzählungen urbane Zentren Javas. Dieses Paper diskutiert den Roman Tarian Bumi (Erdentanz, 2000 von Oka Rusmini, die den Diskurs um den weiblichen Körper und Sexualität de facto noch vor der ‚Pionierin’ der sogenannten sastrawangi eröffnet hat, Ayu Utami. Das Paper möchte einen Beitrag dazu leisten, die Verflechtungen von weiblichen Körperinszenierungen, Tanz und Aspekte der Bewahrung der balinesischen Kultur aufzuzeigen. Ein besonderes Augenmerk liegt auf der Frage, wie die Körperinszenierungen genutzt werden, um die Rolle der Frau in der balinesischen Gesellschaft innerhalb des Spannungsfeldes des hinduistischen Kastensystems, der Hierarchie und vor dem Hintergrund der Problematik von Tourismus, postkolonialer Kritik und Bewahrung balinesischer Kultur im Wandel der Zeit zu charakterisieren.An increasing number of Indonesian women authors have entered the literary stage since the fall of Suharto.

    The M/V Selendang Ayu grounded off Unalaska Island in Alaska on December 8, 2004, and spilled over 1270 m{sup 3} of oil and an unknown quantity of soybeans. The freighter grounded nearshore in a high-wave energy zone along a remote and rugged coastline, a terrain which can cause difficulties for remote sensors in detecting oil slicks. In addition, guano, kelp beds, whale and fish sperm, and releases from fishing activities generated biogenic films on the sea surface that had a signature similar to that of petroleum films. RADARSAT-1 synthetic aperture radar (SAR) imagery was used as part of the response effort to assist in the pollution monitoring effort. This paper described the methodology and results of the RADARSAT-1 analysis. Detailed information on the spill response was reported daily, and provided an opportunity to compare field observations with RADARSAT-1 SAR imagery. Observers recorded observations onto electronic maps during 35 aerial surveillance flights. Fifty-seven incident reports describing the vessel status were also used for comparison. Using screening criteria for the favorable wind and wave conditions, 37 images were available for viewing the wreck, and 22 images were acceptable for oil slick viewing. Image analysis for the wreck suggested that the sensor has the resolution and capability to monitor a grounded freighter. Visual inspection of the images showed that SAR can capture changes in vessel status, such as the gradual sinking of the bow. However, SAR's oil slick detection capability was disappointing due to the significant number of biogenic films in the nearshore areas of Alaska. It was concluded that future work should concentrate on developing a ranking system to indicate analysis confidence that a particular image does in fact contain a petroleum pocket. 25 refs., 2 tabs., 10 figs.

    A comprehensive water quality sampling program was conducted in response to the oil spill that occurred when the M/V Selendang Ayu ship ran aground near a major fishing port at Unalaska Island, Alaska in December 2004. In particular, the sampling program focused on the threat of spilled oil to the local commercial fisheries resources. Spill scientists were unable to confidently model the movement of oil away from the wreck because of limited oceanographic data. In order to determine which fish species were at risk of oil contamination, a real-time assessment of how and where the oil was moving was needed, because the wreck became a continual source of oil release for several weeks after the initial grounding. The newly developed methods and procedures used to detect whole oil during the sampling program will be presented in the Alaska Commercial Fisheries Water Quality Sampling Methods and Procedures Manual which is currently under development. The purpose of the manual is to provide instructions to spill managers while they try to determine where spilled oil has or has not been encountered. The manual will include a meaningful data set that can be analyzed in real time to assess oil movement and concentration. Sections on oil properties and processes will be included along with scientific water quality sampling methods for whole and dissolved phase oil to assess potential contamination of commercial fishery resources and gear in Alaska waters during an oil spill. The manual will present a general discussion of factors that should be considered when designing a sampling program after a spill. In order to implement Alaska's improved seafood safety measures, the spatial scope of spilled oil must be known. A water quality sampling program can provide state and federal fishery managers and food safety inspectors with important information as they identify at-risk fisheries. 11 refs., 7 figs.

  1. Investigation of vessel traffic passing through the Aleutian Islands with discussion of risk factors that could lead to oil pollution

    The oil spill risks posed by marine vessels travelling the North Pacific route from North America to Asia were discussed with reference to the grounding and break-up of the bulk grain ship M/V Selendang Ayu at Unalaska Island in Alaska's Aleutian Islands. The challenge of gathering and categorizing vessel traffic data in the Aleutians was also discussed along with a review of methods for developing an accurate traffic study for this large, remote maritime region. The travelling route passes through, or lies in close proximity to large and valuable commercial fishing grounds as well as the Alaska Maritime National Wildlife Refuge. As most vessels remain in international waters, they do not report their presence to state and national authorities and are exempt from contingency planning requirements. This paper listed the factors affecting risk of damage from oil spills from marine vessels. These include the volume of oil carried; types of oil; proximity to environmentally sensitive areas; fate of spill; location of spill response equipment; number of vessels travelling through the area; time that vessels are in the area; type and age of vessels; environmental factors affecting sailing conditions; factors limiting rescue; and interaction with regulatory agencies. When considered as a whole, these factors can help in deciding the degree and type of contingency planning. In order to estimate traffic through the North Pacific route, the authors compared, combined and extrapolated information from similar datasets. The task involved 3 steps: (1) estimating the number of trans-Pacific voyages through the Aleutians, (2) estimating vessel type, and (3) estimating fuel oil carried by vessel type. It was determined that more than 2,700 ship voyages pass through the Aleutians every year, of which 50 carry a total of 800 million gallons of oil as cargo. It was noted that serious ship accidents occur so infrequently in remote areas that it was impossible to establish an accurate

    The 2002 Summer School on Astroparticle Physics and Cosmology was held at ICTP, in the three weeks from June 17 to July 5. As in previous Schools in this series, the main topics were covered by sets of 3-5 lectures (regular courses); some special topics were presented in dedicated sessions (special lectures); and emphasis was given to the discussion sessions. The main aim of the School was to give an updated survey of astroparticle physics and cosmology, with an emphasis on theoretical aspects. W. Hu introduced and discussed the theory of structure formation, and the most important features of the cosmic microwave background radiation. A closely connected topic, inflation, was reviewed in detail in the lectures of A. Riotto. The connection between dark matter and particle physics was outlined by R. Bernabei. The search for other dark matter candidates, such as monopoles and axions, was discussed by G. Giacomelli and E. Masso. Dark energy and the cosmological constant - the most puzzling aspect of particle and astroparticle physics, according to many - were the topics of the lectures of G. Dvali, who offered many stimulating proposals and speculations. G. Gabadadze reviewed the physics of large extra dimensions, and suggested a number of applications of these ideas in cosmology. Field theory at finite temperature has been presented by M. Laine. S. Sarkar and P. Tinyakov addressed the cosmic rays of ultra-high energies and discussed the puzzles they pose to astrophysics and particle physics. The lectures of W. Buchmueller provided an overview of current ideas about baryogenesis, and in particular the mechanism of leptogenesis - which draws a connection with neutrino masses. A.Yu. Smirnov discussed the status of the solar neutrino problem. An introduction to neutrino astronomy was given by F. Vissani. Finally, L. Rezzolla gave a detailed discussion of the status and perspectives for gravitational wave detection (of great interest for interferometers like VIRGO and

    injection technology is proposed to use for control of the border plasma radiation and plasma-surface interaction in the scrape-off layer [6]. Concepts of the FNS blankets for pure thermal neutron production and for development of thorium fuel cycle for fission reactors have been proposed and considered. It was shown that thermal neutron fluxes as large as 10 15 n/cm 2 /s are feasible in FNS with Be-central stack. The radial structure, neutronics and thermal hydraulic characteristics as well as the U 233 -production rate and opportunities to self-breed tritium in it have been defined.

  5. Outcaste by Choice: Re-Genderings in a Short Story by Oka Rusmini

    Full Text Available Ida Ayu Oka Rusmini is a major contemporary Indonesian author. She has published two novels, Tarian Bumi (2000 and Kenanga (2003a, a collection of short stories, (Sagra, 2001, and a volume of poetry, Patiwangi (2003b, republished in 2007 as Warna Kita, with the omission of some 12 poems. Born in Jakarta in 1967 of Balinese parents, she was a member of the highest Balinese caste, the brahmana caste, but renounced this status, including her title, after her marriage to the East Javanese essayist and poet Arif B. Prasetyo. Oka Rusmini is a graduate of the Indonesian Studies Department, Udayana University, and lives in Den Pasar where she works as a journalist for the Bali Post. Most of Oka Rusmini’s prose works explore the constraints into which the socioreligious practices of caste place all members of society, but most especially women. Both of her novels tell of a woman’s abandonment of her brahmin caste status as the result of her marriage to a sudra. The title of the poetry book, Patiwangi, refers to the ritual practice by which this degradation is confirmed, and the poem which gives the book its title bears the footnote: ‘Patiwangi: pati = death; wangi = fragrant. Patiwangi is a ritual that is performed on a noble women in her Village Temple to remove her noble status as a consequence of having married a man of a lower caste. The ritual often has a serious psychological impact on noble women’ (107. In both novels, and many short stories and poems, their loss of status brings enormous scorn and hardship to the major woman characters. Nevertheless, as we shall see, stepping outside patriarchally-dominated caste ties may also provide an ambiguous freedom for any woman who is positioned to take advantage of the opportunities which the modern, potentially secular, nation state of Indonesia, offers her. In this paper, I am interested in the way in which the short story, ‘Cenana’ (Sagra, 270-318, uses a traditional myth to deal

    This issue of ITER ITA (ITER transitional Arrangements) newsletter contains concise information about the Ministerial Meeting on the ITER site selection (MMI-2) took place in Moscow, Russian Federation, on 28 June 2005. About one hundred participants from the Parties to the ITER Negotiations and the IAEA attended at the Meeting. Mr. A.Yu. Rumyantsev, Director of Rosatom, welcomed the participants and pointed out that the goal of the meeting was to resolve the most difficult issue: to select the site for implementation of the ITER project. Once this decision had been taken, one could expect a swift and successful accomplishment of negotiations and beginning of work on the ITER constriction. Mr. A. Yu. Rumyantsev, Director of Rosatom, welcomed the participants and pointed out that the goal of the meeting was to resolve the most difficult issue: to select the site for implementation of the ITER project. Once this decision had been taken, one could expect a swift and successful accomplishment of negotiations and beginning of work on the ITER construction. Mr. Rumyantsev invited the Heads of Delegations of Japan, the European Union, the People's Republic of China, the Republic of Korea and the United States of America to express the positions of their Parties on the choice of a site. Mr. N. Nakayama, Japanese Minister of Education, Culture, Sports, Science and Technology, recognized that three years had passed since the start of Negotiations on the site issue and that a consensus on the roles of the Host Party and the Non-Host Party had been reached. It was therefore not desirable that both Japan and the EU still advocate their own sites and allow the Negotiations to continue with no prospect of coming to a conclusion. So, considering that the ITER project should be started as soon as possible for the future benefit of humankind, that the six-Party-framework for implementing the ITER project should not be broken, that the ITER project starting smoothly will be a major
