Full textAbstract:
The Tanami oil discovery was made in 1991. The discovery well was drilled from an onshore location on Varanus Island and deviated into the offshore area. A small, 6.8 m oil column was intersected at the top of the Lower Cretaceous Flag Sandstone Member of the Barrow Group. Beneath the moveable oil, a residual zone of 19.8 m was encountered.Petrophysical, petrological and core analysis data indicate different reservoir properties in the moveable oil, residual oil and water zones. These results show that the oil in place has retarded diagenesis and associated reduction in porosity and permeability values.The residual oil column is interpreted to be a result of northward structural tilting in the early Tertiary, causing oil previously trapped to be spilled to the south.

Full textAbstract:
Context Many rare and endangered species are threatened by the effects of hybridisation with their domesticated and often numerically dominant relatives. However, factors that influence interactions between hybridising species are poorly understood, thus limiting our ability to develop ameliorative strategies. Aims Here, we identify family groups and investigate patterns of gene flow between dingoes (Canis lupus dingo) and domestic dogs (C. l. familiaris) in the Tanami Desert of central Australia. We aimed to determine whether human-provided resources facilitate hybridisation or alter typical patterns of dingo breeding and social behaviour. We also ask whether remote townships are arenas for dingo–dog hybridisation. Methods Tissue samples and morphological details were collected from dingo-like animals around two mine sites where humans provide abundant supplementary food and water. Using molecular DNA analyses, we assigned animals to population clusters, determined kinship and the numbers of family groups. Rates of hybridisation were assessed around the mines and in two nearby townships. Key results Of 142 samples from mine sites, ‘pure’ dingoes were identified genetically in 89% of cases. This predominance of dingoes was supported by our observations on coat colour and body morphology. Only 2 of 86 domestic dogs sampled at the two townships showed evidence of dingo ancestry. Around the mine sites, there were two distinct population clusters, including a large family group of 55 individuals around a refuse facility. Conclusions Where superabundant and consistent food, and reliable water, was available, dingo packs were much larger and co-existed with others, contrary to expectations derived from previous research. Dingo sociality and pack structures can therefore be altered where human-provided food and water are constantly available, and this could facilitate accelerated rates of hybridisation. Implications The development of appropriate domestic-waste management strategies should be a high priority in remote areas to ensure only normal rates of population increase by dingoes, and other canids more broadly. It will also potentially impede hybridisation rates if typical canid social and behavioural traits remain intact. Additionally, areas surrounding remote human settlements are likely arenas for accentuated dingo–domestic dog interactions and should be a target for future studies.

Full textAbstract:
The scincid lizard genus Ctenotus is one of the most species-rich genera of squamate reptiles, but few molecular phylogenetic studies have been undertaken on the group. Here we assess molecular and morphological variation within C. piankai and C. duricola, an arid-adapted pair of nominate species characterized by a pattern of thin pale longitudinal lines on a dark background that occur primarily in the western deserts and Pilbara region of Australia. We sequenced mitochondrial DNA and genome-wide restriction-site associated DNA (RAD) from geographically widespread samples of these lizard taxa, with particularly dense sampling from the Pilbara region. Phylogenetic analyses of the mitochondrial cytochrome B gene and approximately 5,000 nuclear loci identified four highly divergent lineages within the two taxa. The four genetically-defined populations were concordant with geography and are distinguishable based on multiple morphological and color pattern characters, despite appearing superficially similar in appearance. Despite limited mtDNA exchange between two lineages in the Pilbara, we found no evidence for ongoing gene flow across the nuclear genome. For the western desert lineages, there was no evidence of introgression for either mtDNA or nDNA in our data. To resolve the taxonomy of the group, we redescribe C. piankai and C. duricola, and recognize the two divergent lineages as new species: C. rhabdotus sp. nov., from the south-eastern Kimberley, Ord, Victoria River and northern Tanami Desert regions of Western Australia and the Northern Territory, and C. pallasotus sp. nov., from the western Pilbara and North West Cape regions of Western Australia.

Full textAbstract:
This item is only available electronically.The newly-discovered Oberon gold deposit, Tanami Goldfields, represents a Paleoproterozoic mesothermal orogenic gold deposit hosted in the Tanami Group. Recent drilling has intersected extensive mineralised zones at various positions within the lower stratigraphy. Studying drillhole TID0065 using a number of different techniques, the project set out to understand the lithostratigraphy of the sequence and its relationship with gold mineralisation, constraints on depositional environments and associated hydrothermal alteration, along with correlations to other deposits in the region. The sequence consists of a dolomitic mudstone, grading up into a phyllite, with a siltstone protolith. This meta-sandstone represents the main host for gold mineralisation and is similar to that seen in the Coyote deposit. Conformably overlying this unit is a rapidly-deposited well-defined turbidite sequence. Gold is also hosted in the overlying Boudin Chert unit, a graphitic, pyrite rich rock that has hosts distinctive diagenetic boudin structures. The Boudin Chert represents a transition into an anoxic sediment-starved environment. Increased clastic input along with a drop in sea level further defines the rest of the sequence, with a siltstone, mudstone and sandstone package and intercalated volcaniclastics and ignimbrites noted in the upper part of the drillhole extending into the Killi Killi Formation. Mineralisation is predominantly stratabound but thrust stacking provides a secondary control to the gold distribution pattern. Gold mineralisation is associated with Na-enrichment and K-depletion; albite is the dominant feldspar in the gold-hosting assemblage. This demonstrates a possible sodic metasomatism of an alkali assemblage. The wide variation in chlorite composition, expressed as varying proportions of chamosite and clinochlore end-members between lithologies, is suggestive of multiple fluid phases and/or alteration events, including possible „seafloor metamorphism‟ prior to hydrothermal activity. Primary alteration in the deposit is represented by an earlier chlorite-sericite assemblage and a later stage calcite-dolomite alteration in certain lithologies at the base of the sequence. Using chlorite thermometry, peak metamorphic temperatures were calculated to be at 366 ± 21 °C (i.e. greenschist facies); conditions reach amphibolite grade less than a kilometre away. Electron probe microanalysis suggests the mineralising fluids were volatile-rich, as demonstrated by the high F content of biotite and apatite. Future exploration potential for deposits of this type should focus on identification of Fe-enriched turbiditic sequences, chlorite-albite-muscovite assemblages and the presence of arsenopyrite. Graphitic oxygen-deprived beds enriched in a range of trace elements with strong pyrite alteration are also good indicators of gold mineralisation.

Organoids are developed from stem cells and serve as three-dimensional model systems for different organs. They have great potential for research and medicine, but also raise philosophical, ethical and legal questions which have rarely been discussed in Germany so far. This thematic study by the interdisciplinary research group (IAG) Gene Technology Report at the Berlin-Brandenburg Academy of Sciences and Humanities offers an overview of current scientific developments, their present and potential application, as well as epistemological, ethical and legal reflections.

This chapter charts the growth of violent Islamism through the prism of strategic scripts introduced in the first chapter. It focuses on the Muslim Brotherhood’s emergence and development of the Secret Apparatus, before looking at the lesser-known organizations of the 1960s such as Takfir wal-Hijra and the Military Academy Group, who resorted to terrorist violence to gain critical mass for their confrontation with the regime. The remainder of the chapter looks at groups like Tanzim al-Jihad, Egyptian Islamic Jihad (EIJ) [al-Jihad al-Islami] and the Egyptian Islamic Group (EIG) [al-Gama’a al-Islamiyya], charting their use of different strategic scripts in their conflict with the regime.

This chapter describes the dances and choreography of Tanaka, a dancer who did not originally belong to the world of butô, but come to be associated with it. He eventually studied with Hijikata and adopted the butô label for part of his career. This chapter includes his solo works of the 70’s (as part of the series Subject, Dance State, Hyperdance, Drive, and Emotion), his collaborations with improvisational musicians such as Derek Bailey and Milford Graves, his experiments with farming as dance training at Body Weather Farm, his involvement with Hijikata, the changes he made to Hijikata’s methods as he adjusted to choreographing for his two groups, Maijuku and Tokason, and finally his later solo dances in the Hijikata mode. Dances considered include Subject (1974), Dance State: Tokyo Arts University Performance (Sept. 28, 1975), Hyperdance (1977), Emotion (1982), Extremely Quick Respiratory Bromide (1983), Form of the Sky (1984), Performance to Commemorate the 1501st Solo Dance of Tanaka Min: The Foundation of the Pure Love-Dance School (1984), Moon at Noon (1985), Dislocated Child’s Body (2002), and Passing through the Body and Sloughing It Off (2005).

Full textAbstract:
The villages in Tana Toraja, Sulawesi, host some of the most lavish feasts in Southeast Asia, especially for funerals or memorials. In addition megaliths were raised for the wealthiest deceased family members. There is also considerable variability in economics, sociopolitical organization, and feasting within the Torajan area. This chapter discusses and tries to explain some of this variability, from low level transegalitarian villages in poor mountainous areas to the proto- or real chiefdom levels of the valley bottoms where paddy rice produces major surpluses. The corporate kindred with its ancestral house as the center of ritual and feasting activities is a distinctive feature of Torajan societies. Slavery was very developed, and secondary burials were strongly associated with elites in order to provide enough time to amass as much wealth as possible for proper funeral feasts. Why funeral feasts feature so prominently in Southeast Asia tribal societies is discussed. Other feasts were hosted by households, reciprocal work groups, lineages, corporate kindreds, villages, districts, and village alliances.

Although natural amino acids are readily available, there is a continuing need for unnatural amino acids. Jon C. Antilla of the University of South Florida has described (J. Am. Chem. Soc. 2007, 129, 5830) a promising approach, based on the enantioselective organocatalytic reduction of imines such as 1 derived from α-keto esters. The aryl group is easily removed to give the primary amine. Mukund P. Sibi of North Dakota State University has developed (J. Am. Chem. Soc. 2007, 129, 4522) an enantioselective Mg catalyst that mediated the addition of benzyl hydrazine 6 to imides such as 5. The initial adduct cyclized to the pyrazolidinone 7. Karl Anker Jørgensen of Aarhus University has reported (Angew. Chem. Int. Ed. 2007, 46, 1983) a complementary protocol for the enantioselective conjugate addition of a nitrogen nucleophile. Enantioselective homologation can also be a powerful approach. Benjamin List of the Max-Planck-Institute, Mülheim has found (Angew. Chem. Int. Ed. 2007, 46, 612; Organic Lett. 2007, 9, 1149) that three-component coupling of acetyl cyanide, an aldehyde and benzylamine under the influence of the Jacobsen thiourea catalyst 10 delivered the onecarbon homologated nitrile 12 in high ee. Other homologation methods are also effective. Li Deng of Brandeis University has shown (Organic Lett. 2007, 9, 603) that under the influence of cinchona-derived quaternary salts, malonates will add to racemic amido sulfones such as 13 to give the β-amino malonate 14 in high ee. Fujie Tanaka and Carlos F. Barbas III of Scripps/La Jolla have found (Angew. Chem. Int. Ed. 2007, 46, 1878) that the simple organocatalyst proline will mediate the aza-Baylis Hillman addition of an unsaturated aldehyde such as 15 to 16 in high ee. The alkene 17 is the kinetic product. On prolonged exposure to the reaction conditions, 17 was equilibrated to the more stable 18 . Ming-Hua Xu and Guo-Qiang Lin of the Shanghai Institute of Organic Chemistry have established (J. Am. Chem. Soc. 2007, 129, 5336) a robust protocol for the enantioselective assembly of -arylated benzylamines such as 21.

Peter Legzdins of the University of British Columbia has described (J. Am. Chem. Soc. 2007, 129, 5372) a stoichiometric tungsten complex that specifically functionalized the primary H of an alkane 1 to give the organometallic 2. Neither the scope of the reactivity of 2 nor the functional group compatibility of this process have as yet been explored. Ruggero Curci of the Università di Bari has reported (Tetrahedron Lett. 2007, 48, 3575) the stereospecific hydroxylation of 1,3-dimethyl cyclohexane 4 to the diol 6. Yasuyuki Kita of Osaka University has developed (Organic Lett. 2007, 9, 3129) conditions for specific benzylic oxidation, converting 7 into 8 with high diastereocontrol. Larry E. Overman of the University of California, Irvine has established (Organic Lett. 2007, 9, 5267) that by using a slow H-atom donor, it was possible to effect intramolecular H abstraction, leading, by oxidation of the intermediate captodatively-stabilized radical, from 9 to the acetate 10. The target C-H of 9 is activated by being adjacent to the ring nitrogen. There are many other ways that nitrogen, easily oxidized, has been used to activate a C-H for bond formation. Takehiko Yoshimitsu and Tetsuaki Tanaka of Osaka University have established (Organic Lett. 2007, 9, 5115) a free-radical route for the homologation of a tertiary amine such as 11 with phenyl isocyanate 12. Chuan He of the University of Chicago has devised (Angew. Chem. Int. Ed. 2007, 46, 5184) an Ag catalyst for the oxidative cyclization of sulfamates such as 15. M. Christina White of the University of Illinois has developed (J. Am. Chem. Soc. 2007, 129, 7274) a ligand system that allows the diastereoselective Pd-mediated allylic oxidation of 16 to 17. The cyclization of 18 to 19 developed (J. Org. Chem. 2007, 72, 8994) by Renhua Fan of Fudan University is thought to be proceeding via H atom abstraction by an intermediate nitrogen radical. The oxidation of the amine 20 to the endocyclic enamine 21 reported (J. Am. Chem. Soc. 2007, 129, 14544) by Maurice Brookhart of the University of North Carolina depended on the ease of oxidative addition of an intermediate alkenyl Co complex into the C-H bond adjacent to the nitrogen. The multistep cyclization of 22 to 23 devised (Organic Lett. 2007, 9, 4375) by Philippe Renaud of the Universität Bern depended on the ease of H atom abstraction adjacent to nitrogen.

Xiang-Ping Hu and Zhuo Zheng of the Dalian Institute of Chemical Physics developed (Organic Lett. 2009, 11, 3226; J. Org. Chem. 2009, 74, 9191) a family of Rh catalysts for the enantioselective hydrogenation of allylic phosphonates such as 1. Hon Wai Lam of the University of Edinburgh established (J. Am. Chem. Soc. 2009, 131, 10386) that an alkenyl heterocycle 3 could be reduced with high ee. The product 4 could be hydrolyzed to the carboxylic acid. Ken Tanaka of the Tokyo University of Agriculture and Technology showed (J. Am. Chem. Soc. 2009, 131, 12552) that an isopropenyl amide 6 could be hydroacylated with high ee. Gregory C. Fu of MIT observed (J. Am. Chem. Soc. 2009, 131, 14231) that nitromethane 9 could be added to the allenyl amide 8 to give 10, the product of γ-bond formation. Robert K. Boeckman Jr. of the University of Rochester devised (Organic Lett. 2009, 11, 4544) what appears to be a general protocol for the construction of alkylated ternary and quaternary centers: enantioselective hydroxymethylation of an aldehyde 11. In another approach to the construction of alkylated quaternary centers, Varinder K. Aggarwal of the University of Bristol demonstrated (Angew. Chem. Int. Ed. 2009, 48, 6289) that an enantiomerically enriched trifluoroborate salt 14 could be added to an aromatic aldehyde 15 with retention of absolute configuration. The salt 14 was prepared from the corresponding high ee secondary benzyl alcohol. Weinreb amides are versatile precursors to a variety of functional groups. Stephen G. Davies of the University of Oxford devised (Organic Lett. 2009, 11, 3254) a chiral Weinreb amide equivalent 17 that could be alkylated with high de. The minor diastereomer from the alkylation was readily separable by silica gel chromatography. Keiji Maruoka of Kyoto University established (Angew. Chem. Int. Ed. 2009, 48, 5014) that a chiral phase transfer catalyst was effective for the enantioselective alkylation of the alkynyl ester 19. Emmanuel Riguet of the Université de Reims Champagne-Ardenne developed (Tetrahedron Lett. 2009, 50, 4283) an improved catalyst for the enantioselective addition of malonate 22 to cyclohexenone 21.

Full textAbstract:
Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan asam humat terhadap pertumbuhan dan produksi tanaman jagung manis serta mengetahui kelayakan usahatani budidaya tanaman jagung manis. Penelitian dilaksanakan dilahan percobaan kampus Politeknik Negeri Jember pada bulan Juni-September 2019 dengan ketinggian tempat 89 mdpl. Penelitian ini menggunakan rancangan praeksperimen melalui pendekatan static group comparison dengan analisis t test dan analisis usahatani. Parameter yang diamati yaitu: tinggi tanaman, jumlah daun, diameter tongkol, panjang tongkol, berat tongkol, tingkat kemanisan dan total berat tongkol. Hasil penelitian menunjukkan pelakuan asam humat dengan dosis 20 kg/ha berpengaruh sangat nyata terhadap tinggi tanaman pada umur 28 HST, 35 HST, dan 42 HST, jumlah daun 14 HST, 35 HST dan 42 HST, berat tongkol dan panjang tongkol. Aplikasi asam humat juga berpengaruh nyata terhadap parameter diameter tongkol dan tingkat kemanisan serta menghasilkan produksi jagung manis sebesar 15 ton/ha dengan nilai R/C Ratio 1,46. Untuk mendapatkan pertumbuhan dan produksi tanaman jagung manis yang lebih optimal disarankan melakukan budidaya jagung manis dengan dosis asam humat yang lebih tinggi

Full textAbstract:
Penyakit Demam Berdarah Dengue (DBD) merupakan penyakit infeksi yang ditularkan melalui gigitan nyamuk Aedes. Penggunaan insektisida sintetis jangka panjang dapat menimbulkan berbagai permasalahan, untuk meminimalisir permasalahan tersebut dapat digunakan larvasida botani yang merupakan insektisida yang bahan dasarnya berasal dari tumbuhan sebagai pengendali larva Aedes sp. Tanaman lidah buaya (Aloe vera) berpotensi sebagai larvasida. Aloe vera mengandung aloin yang berfungsi sebagai penyembuh luka, obat pencahar, antibakteri dan insektisida. Penelitian ini bertujuan untuk mengetahui pengaruh paparan fraksi larut metanol terhadap midgut larva Ae. aegypti. Penelitian ini merupakan penelitian eksperimental dengan rancangan post test only control group, dengan menggunakan analisis probit untuk menilai toksisitas. Hewan coba yang digunakan adalah Ae. aegypti instar III dengan 675 sampel larva, setiap perlakuan mengandung 25 larva dalam 100 ml air. Penelitian dilakukan dengan sembilan perlakuan termasuk dosis yang digunakan adalah 10, 19, 36, 68.6, 130.3, 247.6 dan 500 bagian per juta (ppm), kontrol negatif (air dicampur pelarut tween 80 0.15%) dan kontrol positif (Temephos 0,02 ppm) dengan waktu pengamatan 24 jam. Kandungan aloin dalam fraksi terlarut metanol diidentifikasi dengan Kromatografi Lapis Tipis (KLT). Identifikasi kerusakan midgut larva Ae.aegypti diperiksa secara mikroskopis. Uji larvasida fraksi larut metanol menghasilkan nilai LC50 120.56 ppm dan LC90 875.2 ppm. Fraksi larut metanol kulit lidah buaya menyebabkan kerusakan morfologi organ midgut larva Ae. aegypti di daerah membran peritrofik dan mikrovili. Semakin tinggi dosis fraksi larut metanol, kerusakan yang terjadi semakin parah.

Manor, M. J., and S. J. Piercey. Whole-rock lithogeochemistry, Nd-Hf isotopes, and in situ zircon geochemistry of VMS-related felsic rocks, Finlayson Lake VMS district, Yukon. Natural Resources Canada/CMSS/Information Management, 2021. http://dx.doi.org/10.4095/328992.
Full textAbstract:
The Finlayson Lake district in southeastern Yukon is composed of a Late Paleozoic arc-backarc system that consists of metamorphosed volcanic, plutonic, and sedimentary rocks of the Yukon-Tanana and Slide Mountain terranes. These rocks host >40 Mt of polymetallic resources in numerous occurrences and styles of volcanogenic massive sulphide (VMS) mineralization. Geochemical and isotopic data from these rocks support previous interpretations that volcanism and plutonism occurred in arc-marginal arc (e.g., Fire Lake formation) and continental back-arc basin environments (e.g., Kudz Ze Kayah formation, Wind Lake formation, and Wolverine Lake group) where felsic magmatism formed from varying mixtures of crust- and mantle-derived material. The rocks have elevated high field strength element (HFSE) and rare earth element (REE) concentrations, and evolved to chondritic isotopic signatures, in VMS-proximal stratigraphy relative to VMS-barren assemblages. These geochemical features reflect the petrogenetic conditions that generated felsic rocks and likely played a role in the localization of VMS mineralization in the district. Preliminary in situ zircon chemistry supports these arguments with Th/U and Hf isotopic fingerprinting, where it is interpreted that the VMS-bearing lithofacies formed via crustal melting and mixing with increased juvenile, mafic magmatism; rocks that were less prospective have predominantly crustal signatures. These observations are consistent with the formation of VMS-related felsic rocks by basaltic underplating, crustal melting, and basalt-crustal melt mixing within an extensional setting. This work offers a unique perspective on magmatic petrogenesis that underscores the importance of integrating whole-rock with mineral-scale geochemistry in the characterization of VMS-related stratigraphy.
