REX \u27 96 : an expert guide to revegetation

Agriculture Western Australia has provided coordination and technical input to a powerful source of information on plants for Australian conditions. David Bicknell outlines some of its features and uses. Farmers, local government, advisers and even gardeners often have trouble finding the right plant for the right place for a given purpose. Rather than spend a lot of time, money and effort looking through scattered sources of information, many people stick with a limited number of species year after year. This neglects plants that may be much better suited to the purpose, and also fails to develop Australia\u27s huge range of species. REX\u2796, Revegertation EXpert software, is an exciting use of modern software to make choosing plants easier and more efficient, while giving comprehensive information on each plant

Abnormalities of HLA and β₂microglobulin expression on tumour cells

This thesis describes the genetic events that can lead to the loss of expression of HLA class 1 on tumour cells. Earlier studies, in colorectal cancer, have shown both complete loss of surface HLA A, B & C expression and loss of single allele products using antibodies recognizing either monomorphic or polymorphic HLA determinants. Data presented demonstrates that complete loss of HLA class 1 expression correlates with mutations in β2 microglobulin. In a study of 52 colorectal cell lines, 8 showed mutations in β2 microglobulin leading to loss or reduced HLA expression. In fresh colorectal tumours 9/147 had mutations in β2 microglobulin, occurring at single or di-nucleotide repeat sequences. From these tumours 71 were analyzed for microsatellite instability, associated with the loss of DNA mismatch repair, and 7 (10%) found to be unstable. β2 microglobulin mutations were identified in 5 of these tumors. Therefore, mutations in β2 microglobulin occur more frequently in mismatch repair defective tumours than in colorectal tumours in general (p<0.01). The colorectal cell line HCA-7 lacks expression of HLA-A*0101 based on studies with the polymorphic antibody 142.2, but the normal B cell line (EVA-1224) from the same patient expresses A*0101. This thesis shows that the A*0101 gene, in HCA-7, contains an insertion of a cytidine in a cytidine repeat sequence in exon 4. This mutated A*0101 gene has the similar sequence to that of a rare A*0104'null' allele reported to lack A*0104 expression. In a model system a β2 microglobulin-HLA-A*0201 construct was transfected, using an ecdysone inducible expression system, into CHO cells and expression shown to be under the control of the inducer, Ponasterone A. Functional studies demonstrated the construct to be capable of presenting the flu virus peptide GILGFVFTL to a clone of human A*0201 restricted cytotoxic T cells and for the T cells to efficiently lyse the CHO cells

Bilingual beyond school: Students’ language ideologies in bilingual programs in south-central Spain

This article examines adolescent and late adolescent discourses on bilingualism, bilingual education and the role of English and other additional languages in the current out-of-school lives and future trajectories of Spanish students enrolled in bilingual education programs. The data is part of a larger critical sociolinguistic ethnographic project on the implementation of bilingual education programs in secondary education (organized as English-Spanish CLIL) in Castilla-La Mancha, a region in South-Central Spain. Discourses were mainly elicited through a series of workshop-type and group discussion activities held in classrooms from two semi-private and two public schools, as well as an additional focus group conducted with university students. In total, 12 group events, involving approximately 300 students, were organized and documented through video-recordings, audio-recordings, photographs and fieldnotes. Students’ language ideologies around bilingualism are examined through an inductive qualitative / grounded theory approach. Three themes are identified: (a) the definition of bilingualism and bilingual competence, (b) the place of English (and other additional languages) in students’ current lives and social experiences and; (c) the role assigned to English in future employment and mobility opportunities. These discourses are discussed in relation to recent critical sociolinguistic work on the interconnection between language, multilingualism and neoliberalism. The paper closes with some methodological thoughts regarding the place of linguistic ethnography in the analysis of students’ collective discoursesThe research Project «The Appropriation of English as a Global Language in Castilla-La Mancha Schools: A multilingual, situated and comparative approach» – APINGLO-CLM – (Ref.: FFI2014-54179-C2-2-P), funded by the Spanish Ministry of Economy and Competitiveness (MINECO), 2015-201

Tree windbreaks in the wheatbelt

Windbreaks comprising trees, or tree and shrub combinations, can offer many benefits on wheatbelt farms, particularly for protection of soil, stock, crops and pastures from damaging winds and erosion. Additional benefits include reduced evaporation from farm dams, reduced groundwater recharge, their use as nature conservation corridors and habitats, increased biodiversity including predators of crop and pasture pests, fire control, tree products and improved lifestyle and aesthetics. In other areas and farming systems such as intensive horticulture, man-made windbreaks may be used, but their higher cost makes them unsuited for broadscale agriculture. Man-made windbreaks can be effective in reducing evaporative losses from farm dams in the short to medium-term but become costly if they are engineered to withstand strong winds or last a long time.https://researchlibrary.agric.wa.gov.au/bulletins/1196/thumbnail.jp

Numerical wave optics and the lensing of gravitational waves by globular clusters

We consider the possible effects of gravitational lensing by globular clusters on gravitational waves from asymmetric neutron stars in our galaxy. In the lensing of gravitational waves, the long wavelength, compared with the usual case of optical lensing, can lead to the geometrical optics approximation being invalid, in which case a wave optical solution is necessary. In general, wave optical solutions can only be obtained numerically. We describe a computational method that is particularly well suited to numerical wave optics. This method enables us to compare the properties of several lens models for globular clusters without ever calling upon the geometrical optics approximation, though that approximation would sometimes have been valid. Finally, we estimate the probability that lensing by a globular cluster will significantly affect the detection, by ground-based laser interferometer detectors such as LIGO, of gravitational waves from an asymmetric neutron star in our galaxy, finding that the probability is insignificantly small.Comment: To appear in: Proceedings of the Eleventh Marcel Grossmann Meetin

Native speakerism and the construction of CLIL competence in teaching partnerships: reshaping participation frameworks in the bilingual classroom

© 2020 Informa UK Limited, trading as Taylor & Francis Group. English language education in the region of Castilla-La Mancha (Spain) has undergone significant change in the last decade with the rapid implementation of different types of CLIL-based Spanish-English bilingual programs. This situation places English linguistic competence at the center of controversy given the need for certified bilingual teachers participating in CLIL-type bilingual programs, who must comply with the minimum B2 level of English and are expected to engage in the successful teaching of content subjects. Within this context, this paper draws from a larger multi-sited linguistic ethnography and analyzes the organization of bilingual classroom interactions in a semi-private school that claims to implement a distinct language program built around teaching partnerships between ‘native’ language assistants (NLAs) and content teachers (CTs). We draw from critical research on communicative competence and changing definitions of workers in late capitalism to examine how linguistic and professional hierarchies are reconstructed within this bilingual classroom interactional order.Data in this article belongs to the APINGLO-CLM project ‘The appropriation of English as a global language in Castilla-La Mancha secondary schools: A multilingual, situated and comparative approach’, funded by the Spanish Ministry of Science and Innovation (Plan Nacional I+D + I 2014/Reference: FFI2014-54179-C2-2-P).

Alaska SAR Facility mass storage, current system

This paper examines the mass storage systems that are currently in place at the Alaska SAR Facility (SAF). The architecture of the facility will be presented including specifications of the mass storage media that are currently used and the performances that we have realized from the various media. The distribution formats and media are also discussed. Because the facility is expected to service future sensors, the new requirements and possible solutions to these requirements are also discussed

Hip-Hop echoes in south Madrid teenagers’ soundscapes

This paper draws on findings from a collaborative ethnographic project with 13–14 year old adolescents in an educationally progressive secondary school in Madrid. The project developed as an educational innovation experience during music lessons and allowed students to collaboratively produce multimodal soundscapes on the role of music in their daily lives. This analysis focuses on the place of Hip-Hop in these adolescents’ musical and expressive cultures, especially as traces of Hip-Hop esthetics are incorporated into the projects created during the project. Our analysis suggests that traces of Hip-Hop culture (as a broad global manifestation involving various expressive practices such as rap, dance or graffiti) emerge in a variety of ways in students’ productionsFunding for this collaborative research project came from two sources. On one hand, an intramural research grant awarded to the UAM team (led by the first author) within a research program aimed at collaboration with Brazilian University. On the other hand, a grant awarded by the foundation that runs the school to the music teacher (the second author) to implement novel practices in secondary school music education with the involvement of student
