Ruwatan Murwakala Di Jakarta Dan Surakarta: Telaah Fungsi Dan Makna

Disertasi berjudul Ruwatan Murwakala di TMII Jakarta dan di Desa Sangkrah Pasar Kliwon-Surakarta: Telaah Fleksibilitas, Fungsi, dan Makna ini mengkaji Ruwatan Murwakala sebagai suatu peristiwa sosial budaya yang dibahas dari sudut pandang kajian tradisi lisan. Hal ini sesuai dengan teori Ruth Finnegan dalam Oral Poetry (1977) yang membahas komposisi, cara penyampaian, dan pertunjukan. Ruwatan Murwakala (RM) sebagai suatu ritus/ ritual juga akan dibahas menggunakan teori Ritus Peralihan sesuai daur hidup (life cycle) Rites of Passage teori Arnold van Gennep (1960/1975) berdasarkan ketiga tahapannya, yaitu tahap pertama perpisahan/separation, tahap kedua peralihan/marge, dan tahap ketiga pemulihan/aggregation. Kajian ini membandingkan antara RM golongan sukérta sebagai suatu ritual/upacara dari Surakarta yang masih dilaksanakan masyarakat pendukungnya di dalam komunitasnya sampai saat ini, dengan RM golongan sukérta yang selama ini diselenggarakan di TMII Jakarta di luar komunitasnya—di lingkungan masyarakat urban. Data yang diolah dan dianalisis dalam penulisan disertasi ini merupakan hasil penelitian lapangan dengan metode kualitatif, yaitu melalui teknik wawancara mendalam dan pengamatan terlibat. Hasil analisis dalam penelitian ini menunjukkan adanya perbedaan antara upacara RM yang sampai sekarang masih diselenggarakan di TMII Jakarta dengan RM di Desa Sangkrah Kecamatan Pasar KliwonSurakarta sebagai pusat budaya. Ada fleksibilitas fungsi dan makna dari nilai-nilai yang terkandung di dalam RM bagi golongan sukérta tersebut. Upacara RM masih diselenggarakan sampai sekarang. Artinya, upacara ini dapat diterima masyarakat pendukungnya sesuai dengan perkembangan zaman

Gaucher Disease and Myelofibrosis: A Combined Disease or a Misdiagnosis?

Background: Gaucher disease (GD) and primary myelofibrosis (PMF) share similar clinical and laboratory features, such as cytopenia, hepatosplenomegaly, and marrow fibrosis, often resulting in a misdiagnosis. Case Report: We report here the case of a young woman with hepatosplenomegaly, leukopenia, and thrombocytopenia. Based on bone marrow (BM) findings and on liver biopsy showing extramedullary hematopoiesis, an initial diagnosis of PMF was formulated. The patient refused stem cell transplantation from an HLA-identical sibling. Low-dose melphalan was given, without any improvement. Two years later, a BM evaluation showed Gaucher cells. Low glucocerebrosidase and high chitotriosidase levels were indicative for GD. Molecular analysis revealed N370S/complex I mutations. Enzyme replacement therapy with imiglucerase was commenced, resulting in clinical and hematological improvements. Due to an unexpected and persistent organomegaly, PMF combined with GD were suspected. JAK2V617F, JAK2 exon 12, MPL, calreticulin, and exon 9 mutations were negative, and BM examination showed no marrow fibrosis. PMF was excluded. Twenty years after starting treatment, the peripheral cell count and liver size were normal, whereas splenomegaly persisted. Conclusion: In order to avoid a misdiagnosis, a diagnostic algorithm for patients with hepatosplenomegaly combined with cytopenia is suggested

Parametric resonance and spin-charge separation in 1D fermionic systems

We show that the periodic modulation of the Hamiltonian parameters for 1D correlated fermionic systems can be used to parametrically amplify their bosonic collective modes. Treating the problem within the Luttinger liquid picture, we show how charge and spin density waves with different momenta are simultaneously amplified. We discuss the implementation of our predictions for cold atoms in 1D modulated optical lattices, showing that the fermionic momentum distribution directly provides a clear signature of spin-charge separation.Comment: 6 pages, 3 figures, published versio

Macroscopic fluctuations theory of aerogel dynamics

We consider the thermodynamic potential describing the macroscopic fluctuation of the current and local energy of a general class of Hamiltonian models including aerogels. We argue that this potential is neither analytic nor strictly convex, a property that should be expected in general but missing from models studied in the literature. This opens the possibility of describing in terms of a thermodynamic potential non-equilibrium phase transitions in a concrete physical context. This special behaviour of the thermodynamic potential is caused by the fact that the energy current is carried by particles which may have arbitrary low speed with sufficiently large probability.Comment: final versio

Advancements in Design Research. 11 PhD Theses on Design as we do in Polimi

The book is part of a series that, since 2017, documents the production of the Politecnico di Milano Design Programme, presenting a summary of the doctoral theses defended each year. In the variety of the researched topics (Design Education; Collaborative Processes; Cultural and Creative Companies; Technology for Social Change), a common trait can be found in the continuous need of updated ways of addressing complex problems. It is such need that drives the evolving boundaries of design research forward, not just within our Doctoral Programme, but within all the national and international Doctoral Programmes in Design we are acquainted with

Magnetic dips in the solar wind

Using magnetic data from the HELIOS 1 fluxgate magnetometer, with a 0.2 sec resolution, the structures of several interplanetary discontinuities involving magnetic dips and rotations of the magnetic field vector were investigated. A minimum variance analysis illustrates the behavior of the magnetic field through the transition in the plane of its maximum variation. Using this analysis, quite different structures have been individuated and, in particular, narrow transitions resembling almost one dimensional reconnected neutral sheets. For the thinner cases (scale lengths of the magnetic rotation of the order or smaller than 1,000 km), results show the observed structures could be the nonlinear effect of a resistive tearing mode instability having developed on an originally one dimensional neutral sheet at the solar corona

Temperature-dependent resistivity of suspended graphene

In this paper we investigate the electron-phonon contribution to the resistivity of suspended single layer graphene. In-plane as well as flexural phonons are addressed in different temperature regimes. We focus on the intrinsic electron-phonon coupling due to the interaction of electrons with elastic deformations in the graphene membrane. The competition between screened deformation potential vs fictitious gauge field coupling is discussed, together with the role of tension in the suspended flake. In the absence of tension, flexural phonons dominate the phonon contribution to the resistivity at any temperature $T$ with a $T^{5/2}_{}$ and $T^{2}_{}$ dependence at low and high temperatures, respectively. Sample-specific tension suppresses the contribution due to flexural phonons, yielding a linear temperature dependence due to in-plane modes. We compare our results with recent experiments.Comment: 11 pages, 3 figure
