An LIA+EDQNM strategy to study shocked turbulent mixtures
No full textDirect numerical simulations (DNS) of the interaction of shock waves with turbulent mixtures are only affordable for very low Reynolds numbers. We propose here to couple the Linear Interaction Analysis (LIA) with an Eddy-Damped Quasi-Normal Markovian (EDQNM) model to get inexpensive valuable information at large Reynolds number

Luqman Hakim Abbas, S.Si., M.Pd.
Kata kunci: Lembar Kerja Peserta Didik (LKPD), Problem Based Learning (PBL), energi terbarukan.
Penelitian ini didasari oleh hasil analisis kebutuhan di MAN 2 Blitar yang menunjukkan bahwa Lembar Kerja Peserta Didik (LKPD) yang digunakan masih bersifat umum dan belum sepenuhnya sesuai dengan pedoman pembelajaran dari kurikulum merdeka. Selain itu, LKPD yang ada belum mengintegrasikan aktivitas belajar yang melibatkan peserta didik secara langsung dalam proses penemuan dan penerapan konsep fisika. Akibatnya, sebagian besar LKPD di MAN 2 Blitar belum mampu memberikan pengalaman belajar yang memadai dan belum dapat mengembangkan kemampuan berpikir peserta didik secara optimal. Hal ini berdampak pada hasil belajar yang kurang memuaskan. Berdasarkan hal tersebut, peneliti mengembangkan lembar kerja peserta didik (LKPD) berbasis problem based learning (PBL) untuk meningkatkan hasil belajar peserta didik kelas X MAN 2 Blitar pada materi energi terbarukan.
Jenis penelitian yang digunakan dalam penelitian ini adalah Research and Development (R&D) yang mengacu pada model 4D. Model ini terdiri dari empat tahapan define, design, development, dan disseminate. Pada penelitian tahap pertama populasi penelitian adalah seluruh peserta didik yang telah menerima materi energi terbarukan. Sampel penelitian pada tahap pertama adalah kelas XI B. Pada penelitian tahap kedua populasi penelitian adalah seluruh peserta didik kelas X MAN 2 Blitar. Sampel penelitian terpilih adalah kelas X J sebagai kelas kontrol dan kelas X I sebagai kelas eksperimen. Instrumen pengumpulan data terdiri dari lembar validasi ahli materi, ahli media, tenaga pendidik mata pelajaran fisika, angket respons peserta didik, dan soal post test yang diberikan di kelas kontrol dan kelas eksperimen.
Hasil penelitian dan pengembangan menunjukkan bahwa: (1) Proses pengembangan lembar kerja peserta didik (LKPD) berbasis problem based learning (PBL) pada materi energi terbarukan untuk peserta didik kelas X di MAN 2 Blitar menggunakan model 4D yang mencakup empat tahap utama yaitu Define (Pendefinisian), Design (Perancangan), Development (Pengembangan), Disseminate (Penyebarluasan produk). (2) Hasil dari analisis data angket validasi menunjukkan skor rata-rata hasil validasi ahli media adalah 4,37 dengan kategori sangat valid/sangat layak dan hasil analisis data angket validasi ahli materi adalah 3,65 dengan kategori valid/layak. (3) Hasil analisis keterbacaan diperoleh nilai rata-rata respon peserta didik adalah 4,12 dengan kategori layak/mudah digunakan. (4) Berdasarkan hasil uji-t sampel bebas memperoleh nilai signifikasi (2-tailed) 0,001< 0,05 menunjukkan bahwa H1 diterima dan H0 ditolak. Sehingga dapat disimpulkan bahwa penggunaan LKPD berbasis PBL lebih efektif dalam meningkatkan hasil belajar daripada pembelajaran tanpa menggunakan media LKPD berbasis PBL. Sehingga dapat dinyatakan bahwa media pembelajaran LKPD berbasis PBL ini efektif
Genetic variability and relationship of banana cultivars (musa l.) from East Java, Indonesia based on the internal transcribed spacer region nrdna sequences
No full textA genetic variability and relationship study subjected to 41 banana cultivars from East Java based on nrDNA sequences of the ITS region was conducted. It would be useful to consider the genomic identification, genetic conservation strategy, and for further banana improvement. ITSL and ITS4 primers were used to amplify the ITS region. Results show that the ITS region DNA sequences length of 41 banana cultivars examined varied from 631 bp to 651 bp. It showed high variability with conservation level G+C content of 62.79%. Total aligned and selected ITS region DNA sequences was 656 bp comprising 346 positions (52.74%) as conserved region, 223 positions (33.99%) as variable sites (polymorphic) and 87 positions (13.26%) alignment gaps. About 143 positions (64.13%) of the variable positions were potentially parsimony informative and 80 positions (35.87%) were singleton variables. The singletone variation sequences spesific to certain banana cultivars may be proposed as identification barcodes. The haplotype diversity was very rich (Hd=1.00), resulted 41 haplotypes with none of haplogroup. Haplotype distribution map revealed the lineage pattern of banana cultivars from East Java. They were presummably derived from common ancestors and the same population in East Java mainland which then experienced an evolution process, dispersed by human migration both in and out, and became isolated to the islands. Genetic relationship reconstruction using NJ algorithm resulted in a tree and classification better than MP algorithm. It was clustered according to its geomic group, into 3 main clades i.e. AA/AAA, AAB and ABB. The ITS region nrDNA sequences was proven powerful in classifying until cultivar level of bananas. All 41 banana cultivars examined are recommended for genetics conservation
Visually Enhanced Python Functions for Clinical Equality of Measurement Assessment
Get PDFEquivalence testing requires specific procedures usually provided by specialized statistical software. The proposed package includes customized methods to assess biomedical equivalence and focuses on translating the outcomes into visual reports. The functions are coded in an object-oriented framework, contain improved plots or novel graphs to facilitate interpretation of the results, and are accompanied by console textual outputs to support users with additional explanations. Special attention has been devoted to verifying the preliminary assumptions of the statistical tests with automatic routines. The current module covers four aspects of biomedical statistics (equivalence, Bland--Altman and ROC analyses, effect size, and confidence intervals interpretation), offering these methodologies to the biomedical community as accessible stand-alone functions. The manuscript defines software's functions and innovations with examples and theoretical explanations.@inproceedings{FedCSIS202232,

The Bonesetter's Daughter: a Study in the Exposure of Chinese Culture
Get PDFRosita, Lia. 2013. The Bonesetter's Daughter: A Study in the Exposure of Chinese Culture. Study Program of English, Department of Languages and Literature, Faculty of Cultural Studies, Universitas Brawijaya.Supervisor: Dyah Eko Hapsari; Co-supervisors: Fredy NugrohoKeywords: Chinese culture, Chinese traditions, superstitions belief.Amy Tan is one of famous Chinese – American novelist who produces so many literary works. The Bonesetter's Daughter is one of Tan's novels that published in 2001. The writer chooses Tan's novel as her material object because the novel has interesting topic to analyze that is about the life of Chinese immigrants. In addition the writer uses Chinese studies especially about Chinese culture and tradition as her guidance to analyze the novel. The result of this study shows that there are so many exposures of Chinese culture which are portrayed in Tan's The Bonesetter's Daughter. The writer finds about how Chinese – American people enliven their original culture in the aspect Chinese tradition in their life in America, for example is about celebrating Chinese traditions as Chinese immigrant in America. The novel also presents the exposure of Chinese belief, like how the characters in novel believe in the existence of ghost and the power of dragon bone. From the result the writer concludes that Chinese people is a kind of strict people especially in keeping their original tradition wherever they stay and the novel shows how Tan exposes the idea about the importance of rerouting Chinese culture for Chinese – American

MATERIAL CULTURE. AN ESSENTIAL SUBJECT OF THE ITALIAN DIASPORA
No full textThe contemporary folklore appears in everyday life taking many free and unofficial forms across the vitality and diversity of social practices that call for renewed approaches, in Europe and Italy and abroad, following the path of European diaspora. Evaluating the multiplicity of folklore meanings and its capacity to integrate interactions between traditional and contemporary expressions and appropriations in specific contexts, the author explores the practicality of a new idea of folklore as sustainable, popular and
domestic creativity on material and immaterial goods. Following the precious path indicated in 2005 by the American anthropologist Luc Eric Lassiter, the author is turning from “participant observation” to the “collaborative ethnography”. Collaboration between ethnographers and subjects has long been a product of the close, intimate relationships that define ethnographic research. Collaboration also preconditions and shapes research design as well as its dissemination. As a result, ethnographic subjects are shifting from being informants to being consultants. The emergence of collaborative ethnography highlights this relationship between consultant and ethnographer, moving it to centre stage as a calculated part not only of fieldwork but also of the writing process itself, as Lassiter suggests in The Chicago Guide to Collaborative Ethnography

"The Schizoid Narrator and the Paranoid Reader in Patrick McGrath's Spider"
No full textThe essay discusses the relationship between two textual realizations, that of the unreliable narrator, represented in the novel by a man suffering from a schizoid personality disorder, and thet of the so called paranoid reader -- created by modernist New-Criticism and cajoled by several postmodernist writers.
Secondarily it discusses the polarities represented by schizoid narrator and paranoid reader as enecting two different kinds of delirium and, finally, to compare the interaction between the two to what takes place between patient and analyst. The aim is also to offer a reading which can be applied to other works by the same author, since they all seem to follow a similar pattern, both structurally and ideologically
Statistics of the subgrid scales after the shock-turbulence interaction
No full textThe interaction of a normal shock with isotropic turbulence (IT) represents a basic problem for studying some of the phenomena associated with high speed flows, such as hypersonic flight, supersonic combustion and Inertial Confinement Fusion (ICF). In general, in practical applications, the shock width is much smaller than the turbulence scales and the upstream turbulent Mach number is modest. In this case, recent high resolution shock-resolved Direct Numerical Simulations (DNS) (Ryu and Livescu, J. Fluid Mech., 756, R1, 2014) show that the interaction can be described by the Linear Interaction Approximation (LIA). By using LIA to alleviate the need to solve the shock, DNS post-shock data can be generated at much higher Reynolds numbers than previously possible. Here, such results with Taylor Reynolds number around are used to investigate the properties of the subgrid scales (SGS). In particular, it is shown that the shock interaction decreases the asymmetry of the SGS dissipation PDF as the shock Mach number increases, with a significant enhancement in size of the regions and magnitude of backscatter
