A.R Baswedan dan PAl: Potret Nasionalisme Warga Keturunan perspektif sosiopolitik historis
No full textIn this article, the authors review about A.R. Baswedan
and his movement through the Arab Party of Indonesia (PAl).
A.R Baswedan is an Arab descendant known as the pioneer
of independence of the Republic of Indonesia. The author
through historical socio-political studies found that A.R
Baswedan is an example of Arabic descent who counter
Arabism and views between the Arab descendants and the
descendants of indigenous Indonesians are the same or
equal and the same fate. They both have one nationality,
Indonesia. This fusion attitude in the Indonesian citizenship
and nationality equation is evident in its movement within
the PAl.

A.R. Luria: Ideas and Prospects of Their Development in Pedagogical Psychology of the Twenty-first Century
No full textA.R. Luria’s ideas are well-known and recognized both in Russia and abroad. Scientists from different countries are actively working in neuropsychology, a part of the psychological science developed by A.R. Luria. The author has shown the relevance and importance of the neuropsychological approach to the pedagogical psychology problems and the availability to choose an adequate educational and nurturing strategy from these standpoints. The study seeks to rethink and assess the importance of A.R. Luria’s main ideas from the modern pedagogical psychology’s standpoints. The characteristic of the main theoretical provisions has been set forth based on the analysis of A.R. Luria’s academic papers and the main directions and prospects for the development of A.R. Luria’s ideas in the modern psychological pedagogical science have been determined. A.R. Luria’s academic papers most sought by the modern researchers have been noted. The study is based on the materials of the thesis researches on the pedagogical psychology problems conducted in the beginning of the twenty-first century, A.R. Luria’s papers, the publications of other researchers who have studied his contribution to the psychological science. The study results show that A.R. Luria has significantly contributed to the development of the pedagogical psychology problems. A.R. Luria’s ideas on the interaction of the humanitarian and science knowledge in the human comprehensive study, the cultural and historical understanding of the psychical functions development, and the language evolution in the music language study for the musical education development seem most promising for the pedagogical psychology development. Note has been taken of the importance of A.R. Luria’s ideas for the elaboration of the relevant problems of the training and development of a person at any age; the study of individual and typical features in mastering a foreign language; the study of the semantics of speech and means of coding meanings in the context of professional training of psychologists and teachers, specialists in the field of artistic creativity. The analysis of A.R. Luria’s main ideas facilitates the deeper understanding of the modern problems of the pedagogical psychology theory and practice
Incorporation of acceleration effects into the one-dimensional-turbulence model, with application to turbulent combustion and shock-turbulence interactions
No full textOne-dimensional turbulence (ODT) is a stochastic simulation in which 3D turbulence effects are captured on a notional 1D line of sight by introducing instantaneous spatial re-arrangements (maps) that represent advection by notional turbulent eddies. These eddy events incorporate the possibility of kinetic-energy changes that are equal and opposite to changes of other forms of energy such as the gravitational potential energy change due to a re-arrangement of a vertical density profile. This illustrates that motion aligned with an applied force, in this case gravitation , can be associated with energy change. Using this principle, we 1) present a model of turbulence interaction with the dilatational acceleration caused by thermal expansion in flames and show results for a turbulent counterflow flame with comparison to DNS and 2) present a model for shock-induced turbulence and show results for mixing width growth in a shock tube with comparison to experiments
ODTLES: A multi-scale ansatz for highly turbulent flows
No full textWe use ODTLES, a multi-dimensional extension of the One-Dimensional-Turbulence model (ODT). ODT describes turbulent advection on a 1D sub-domain using a stochastic process for turbulent advection. These 1D sub-domains are coupled to obtain a 3D approach. ODTLES is applied to channel flow. Preliminary results for the pdf of the wall shear stress are compared to DNS
Investigating interventions in Alzheimer's disease with computer simulation models
No full textProgress in the development of therapeutic interventions to treat or slow the progression of Alzheimer's disease has been hampered by lack of efficacy and unforeseen side effects in human clinical trials. This setback highlights the need for new approaches for pre-clinical testing of possible interventions. Systems modelling is becoming increasingly recognised as a valuable tool for investigating molecular and cellular mechanisms involved in ageing and age-related diseases. However, there is still a lack of awareness of modelling approaches in many areas of biomedical research. We previously developed a stochastic computer model to examine some of the key pathways involved in the aggregation of amyloid-beta (A?) and the micro-tubular binding protein tau. Here we show how we extended this model to include the main processes involved in passive and active immunisation against A? and then demonstrate the effects of this intervention on soluble A?, plaques, phosphorylated tau and tangles. The model predicts that immunisation leads to clearance of plaques but only results in small reductions in levels of soluble A?, phosphorylated tau and tangles. The behaviour of this model is supported by neuropathological observations in Alzheimer patients immunised against A?. Since, soluble A?, phosphorylated tau and tangles more closely correlate with cognitive decline than plaques, our model suggests that immunotherapy against A? may not be effective unless it is performed very early in the disease process or combined with other therapies

The IPHAS catalogue of H alpha emission-line sources in the northern Galactic plane
No full textWe present a catalogue of point-source H alpha emission-line objects selected from the INT/WFC Photometric Ha Survey (IPHAS) of the northern Galactic plane. The catalogue covers the magnitude range 13 <= r' <= 19.5 and includes Northern hemisphere sources in the Galactic latitude range -5 degrees < b < 5 degrees. It is derived from similar to 1500 deg(2) worth of imaging data, which represents 80 per cent of the final IPHAS survey area. The electronic version of the catalogue will be updated once the full survey data become available. In total, the present catalogue contains 4853 point sources that exhibit strong photometric evidence for Ha emission. We have so far analysed spectra for similar to 300 of these sources, confirming more than 95 per cent of them as genuine emission-line stars. A wide range of stellar populations are represented in the catalogue, including early-type emission-line stars, active late-type stars, interacting binaries, young stellar objects and compact nebulae.
The spatial distribution of catalogue objects shows overdensities near sites of recent or current star formation, as well as possible evidence for the warp of the Galactic plane. Photometrically, the incidence of Ha emission is bimodally distributed in (r' - i'). The blue peak is made up mostly of early-type emission-line stars, whereas the red peak may signal an increasing contribution from other objects, such as young/active low-mass stars. We have cross-matched our H alpha-excess catalogue against the emission-line star catalogue of Kohoutek & Wehmeyer, as well as against sources in SIMBAD. We find that fewer than 10 per cent of our sources can be matched to known objects of any type. Thus IPHAS is uncovering an order of magnitude more faint (r' > 13) emission-line objects than were previously known in the Milky Way
