description: We present near-IR (J,H,Ks) photometry for 27 of the 28 candidate Herbig Ae/Be stars in the Small and Large Magellanic Clouds identified via the EROS1 and EROS2 surveys as well as near-contemporaneous optical (H-alpha) spectroscopy for 21 of these 28 candidates. Our observations extend previous efforts to determine the evolutionary status of these objects. We compare the IR brightness and colors of a subset of our sample with archival ground-based IR data and find evidence of statistically significant photometric differences for ELHC 5, 7, 12, 18, and 21 in one or more filter. In all cases, these near-IR photometric variations exhibit a grey color as compared to earlier epoch data. The ~1 magnitude IR brightening and minimal change in the H-alpha emission strength we observe in ELHC 7 is consistent with previous claims that it is a UX Ori type HAe/Be star, which is occasionally obscurred by dust clouds. We also detect a ~1 magnitude IR brightening of ELHC 12, but find little evidence of a similar large-scale change in its H-alpha line strength, suggesting that its behavior could also be caused by a UX Ori-like event. The ~0.5 magnitude IR variability we observe for ELHC 21, which also exhibited little evidence of a change in its H-alpha emission strength, could conceivably be caused by a major recent enhancement in the density of the inner disk region of a classical Be star. We also report the first near-IR photometry for two ESHC stars and the first H-alpha spectroscopy for one ELHC and five ESHC stars. Although H-alpha emission is detected in all of these new observations, they do not exhibit a strong near-IR excess. It is therefore possible that many of these objects may be classical Be stars rather than Herbig Ae/Be stars.

description: An analytical insight into the symmetry breaking mechanisms underlying the transition from Josephson to self-trapping regimes in Bose-Einstein condensates is presented. We obtain expressions for the ground state properties of the system of a gas of attractive bosons modelized by a two site Bose-Hubbard hamiltonian with an external bias. Simple formulas are found relating the appearance of fragmentation in the condensate with the large quantum fluctuations of the population imbalance occurring in the transition from the Josephson to the self-trapped regime.

description: We consider quantum algebras of observables associated with subregions in theories of Einstein gravity coupled to matter in the $G_N\rightarrow 0$ limit. When the subregion is spatially compact or encompasses an asymptotic boundary, we argue that the algebra is a type II von Neumann factor. To do so in the former case we introduce a model of an observer living in the region; in the latter, the ADM Hamiltonian effectively serves as an observer. In both cases the entropy of states on which this algebra acts is UV finite, and we find that it agrees, up to a state-independent constant, with the generalized entropy. For spatially compact regions the algebra is type II$_1$, implying the existence of an entropy maximizing state, which realizes a version of Jacobson's entanglement equilibrium hypothesis. The construction relies on the existence of well-motivated but conjectural states whose modular flow is geometric at an instant in time. Our results generalize the recent work of Chandrasekaran, Longo, Penington, and Witten on an algebra of operators for the static patch of de Sitter space.

Noninteracting Fermions in infinite dimensions

description: Usually, we study the statistical behaviours of noninteracting Fermions in finite (mainly two and three) dimensions. For a fixed number of fermions, the average energy per fermion is calculated in two and in three dimensions and it becomes equal to 50 and 60 per cent of the fermi energy respectively. However, in the higher dimensions this percentage increases as the dimensionality increases and in infinite dimensions it becomes 100 per cent. This is an intersting result, at least pedagogically. Which implies all fermions are moving with Fermi momentum. This result is not yet discussed in standard text books of quantum statistics. In this paper, this fact is discussed and explained. I hope, this article will be helpful for graduate students to study the behaviours of free fermions in generalised dimensionality.

description: В настоящее время нефтяные компании большое внимание уделяют вопросам разработки карбонатных коллекторов, характеризующихся низкими коллекторскими свойствами. Чаще всего это довольно плотные известняки и доломиты с низкой пористостью и низкой проницаемостью. Такие коллекторы относятся к трудноизвлекаемым запасам. Отложения франского яруса (пласт D3fr) Чинаревского нефтегазоконденсатного месторождения характеризуются большими глубинами залегания, до 5 км, блоковым строением и сложным характером коллекторов: нижняя часть пласта сложена трещиноватыми известняками и доломитами органогенными, органогенно-детритовыми, биогермными, верхняя часть является терригенной и представлена органогенными известняками, чередующимися с глинистыми прослоями. До недавнего времени в карбонатных среднедевонских отложениях было утверждено две залежи – афонинская и бийская. Сегодня возникает необходимость детального изучения залежи пласта D3fr, которая в настоящее время вскрыта 6 скважинами. Для планирования бурения новых скважин на пласт D3fr необходимо построить геологическую модель, основой которой являются результаты интерпретации геофизических данных, лабораторного анализа керна, испытаний пластов. В связи со сложным геологическим строением коллекторов франского яруса и отсутствием петрофизической модели на пласт D3fr для интерпретации скважинных данных необходимо было получить корреляционные связи между петрофизическими параметрами, измеренными на образцах керна. В связи с этим цель данной работы заключается в построении петрофизической модели пласта D3fr с трудноизвлекаемыми запасами и определении петрофизических параметров разреза для геологического моделирования и фациального прогноза. В работе получены устойчивые петрофизические зависимости, позволившие выполнить анализ коллекторских свойств пласта D3fr в карбонатной и терригенной частях на основе комплексного анализа результатов лабораторных исследований керна, испытаний и геофизических данных. Это послужило основой для геологического и фациального моделирования пласта D3fr и планирования бурения.

description: We show results based on a large suite of N-Body/SPH simulations of isolated, flat dwarf galaxies, both rotating and non-rotating. The main goal is to investigate possible mechanisms to explain the observed dichotomy in radial stellar metallicity profiles of dwarf galaxies: dwarf irregulars (dIrr) and flat, rotating dwarf ellipticals (dE) generally possess flat metallicity profiles, while rounder and non-rotating dEs show strong negative metallicity gradients. These simulations show that flattening by rotation is key to reproducing the observed characteristics of flat dwarf galaxies, proving particularly efficient in erasing metallicity gradients. We propose a "centrifugal barrier mechanism" as an alternative to the previously suggested "fountain mechanism" for explaining the flat metallicity profiles of dIrrs and flat, rotating dEs. While only flattening the dark-matter halo has little influence, the addition of angular momentum slows down the infall of gas, so that star formation (SF) and the ensuing feedback are less centrally concentrated, occurring galaxy-wide. Additionally, this leads to more continuous SFHs by preventing large-scale oscillations in the SFR ("breathing"), and creates low density holes in the ISM, in agreement with observations of dIrrs. Our general conclusion is that rotation has a significant influence on the evolution and appearance of dwarf galaxies, and we suggest angular momentum as a second parameter (after galaxy mass as the dominant parameter) in dwarf galaxy evolution. Angular momentum differentiates between SF modes, making our fast rotating models qualitatively resemble dIrrs, which does not seem possible without rotation.

THEORETICAL REVIEW OF EMISSION OF LIGHT FROM QUANTUM WELL AS A  RESULT OF ELECTRON-HOLE RECOMBINATION
Creators: name: ENTONIOS FIKRE SIBANI
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: The materials I have  to be used for this review work are different journals, articles, handbooks
and reference books. These are  available in the internet and the references.  In semiconductor
photonic device fabrication, an important objective is to produce as much light as possible from
the device. In these devices, photons are released when electrons recombine with holes during
transitioning from a high energy state to a lower one. Unfortunately, electron-hole recombination
does not always result in the formation of photon. There are three basic types of recombination:
the first results in the formation of a photon and is called radiative recombination and the second
and the third, known as non-radiative and Auger recombination respectively, result in the heating
of the device and do not produce photons. All three processes occur simultaneously in the
device. This project work discusses the theoretical review of emission of light from quantum
wells as a result of electron-hole recombination. Quantum wells are thin layered semiconductor
structures in which we can observe and control many quantum mechanical effects. This leads to
the electrons and the holes being confined in different layers of the semiconductor.  In order to
describe the band gap energy, the Schrödinger equation is very important. The solution of the
Schrodinger equation for the electron energy, in the periodic potential created by the collection
of atoms in a crystal lattice, results in splitting of the atomic energy levels and the formation of
energy bands. This review work also addresses light incident on semiconductor materials with
the photons interacting with the material. Depending on their energy and the recombination rate,
the process can result in thermal or non-thermal equilibrium.

description: In this thesis a set of methods identifying minijet from final state particles in the relativistic heavy ion collision events is established and the parameter dependence has been investigated in Au+Au collisions at $\sqrt s= 200$GeV using a multiphase transport model (AMPT). It is found that the number of minijets reduces with the increasing of collision parameter and raises with the increasing of c.m energy. Furthermore, we analyze the rapidity and momentum distribution inside minijets identified using this method.

description: На основе детальных полевых исследований пересмотрено строение разреза «Талышман» (Учалинский район Республики Башкортостан). Снизу вверх в нем следуют: 1) вулканокластические граувакки, 2) пачка переслаивания тонкослоистых известняков и кремней с массивными органогенными известняками в кровле, 3) кремни, 4) вулканокластические граувакки, плагиоклазовые и пироксен-плагиоклазовые порфириты. Принято считать, что слои 1–3 относятся к ильтибановской толще (D1), а слой 4 – к ирендыкской свите (D2ef1). Строение разреза «Талышман» сходно со строением разреза ускульской толщи. Граувакки и известняки обоих разрезов имеют одинаковый геохимический состав. На этой основе сделан вывод о соответствии слоев 1 и 2 разреза «Талышман» ускульской толще. Следовательно, кремни слоя 3 относятся к верхнему эмсу (конодонтовые зоны serotinus и patulus). Резкий переход от органогенных известняков к кремням (граница слоев 2 и 3) обусловлен сменой мелководных обстановок на глубоководные и сопоставляется с глобальным событием Delaje, которое проявилось повсеместным повышением уровня океана. Верхнеэмсские кремни разреза «Талышман» (слой 3) имеют низкие значения отношений U/Th, V/Cr, Ni/Co, коэффициента стагнации и величины «аутигенный U», что указывает на окислительные обстановки седиментации. Относительно высокие значения цериевой аномалии (1,5–1,8, в среднем 1,5), отношения Ce/La (1,7–2,8, в среднем 2,2) и низкие содержания марганца (221–381 г/т) указывают на отсутствие в кремнях продуктов подводных металлоносных гидротерм. Отрицательная аномалия европия (0,58–0,84) объясняется присутствием в кремнях примеси обломочного или глинистого материала. По результатам построения диаграмм Zr/ Sc-Th/Sc и V–Ni–Th×10 предполагается, что ее состав близок к составу основных магматических пород. Этот вывод подтверждается при анализе содержаний элементов в кремнях, нормированных на PAAS.

description: Kernelization algorithms for the {\sc cluster editing} problem have been a popular topic in the recent research in parameterized computation. Thus far most kernelization algorithms for this problem are based on the concept of {\it critical cliques}. In this paper, we present new observations and new techniques for the study of kernelization algorithms for the {\sc cluster editing} problem. Our techniques are based on the study of the relationship between {\sc cluster editing} and graph edge-cuts. As an application, we present an ${\cal O}(n^2)$-time algorithm that constructs a $2k$ kernel for the {\it weighted} version of the {\sc cluster editing} problem. Our result meets the best kernel size for the unweighted version for the {\sc cluster editing} problem, and significantly improves the previous best kernel of quadratic size for the weighted version of the problem.

description: Quantum data access and quantum processing can make certain classically intractable learning tasks feasible. However, quantum capabilities will only be available to a select few in the near future. Thus, reliable schemes that allow classical clients to delegate learning to untrusted quantum servers are required to facilitate widespread access to quantum learning advantages. Building on a recently introduced framework of interactive proof systems for classical machine learning, we develop a framework for classical verification of quantum learning. We exhibit learning problems that a classical learner cannot efficiently solve on their own, but that they can efficiently and reliably solve when interacting with an untrusted quantum prover. Concretely, we consider the problems of agnostic learning parities and Fourier-sparse functions with respect to distributions with uniform input marginal. We propose a new quantum data access model that we call "mixture-of-superpositions" quantum examples, based on which we give efficient quantum learning algorithms for these tasks. Moreover, we prove that agnostic quantum parity and Fourier-sparse learning can be efficiently verified by a classical verifier with only random example or statistical query access. Finally, we showcase two general scenarios in learning and verification in which quantum mixture-of-superpositions examples do not lead to sample complexity improvements over classical data. Our results demonstrate that the potential power of quantum data for learning tasks, while not unlimited, can be utilized by classical agents through interaction with untrusted quantum entities.

description: В статье приводится описание геологического строения Приграбенного блока, расположенного в восточной части Восточно-Уральского прогиба на границе с Челябинским грабеном. В стратиграфическом разрезе снизу вверх выделяются четыре толщи: тугундинская (C1v tg), биргильдинская (C1v-s bg), еткульская (C1s et) и ухановская (C2m uh), каждая из которых в разных объемах содержит углеродистые отложения. Биргильдинские черные сланцы, имеющие в своем составе Сорг в пределах 0,5–2,7% (среднее 1,3%), относятся к низкоуглеродистому типу. Экзотермический эффект в них происходил в основном в интервале температур 570–660 °С, что соответствует зеленосланцевой фации регионального метаморфизма. На диаграмме A-S-C породы тугундинской и еткульской толщ в большинстве своем укладываются соответственно в поля терригенно-углеродистой и карбонатно-углеродистой формаций. Образования биргильдинской толщи приблизительно поровну разбросаны по карбонатно-углеродистому и кремнисто-углеродистому полям и заметно меньше – терригенно-углеродистому. В ранневизейское время осадки в пределах Приграбенного блока (тугундинская толща) отлагались в относительно малоглубинных условиях. В поздневизейское время (терригенные породы нижней части разреза биргильдинской толщи) глубина водного бассейна несколько увеличилась, а в серпуховское (карбонатные породы верхней части разреза биргильдинской толщи, еткульские отложения) вновь происходит постепенная регрессия и обмеление бассейна, которое продолжалось вплоть до московского времени, когда накапливались обломочные породы ухановской толщи. Отложение осадочных пород тугундинской толщи происходило в переходной от островодужной к коллизионной геодинамической обстановке, источником терригенного материала были преимущественно кислые и основные магматические породы. Для биргильдинской и еткульской толщ характерны коллизионная обстановка накопления и продукты разрушения главным образом основных магматических пород.

description: Многие месторождения нефти Российской Федерации, а также ряда зарубежных стран приурочены к болотам, заболоченным и пойменным территориям. Известно, что при добыче, транспортировке нефти и нефтепродуктов в РФ из-за разливов наблюдаются их существенные потери (до 7%) и негативное влияние на окружающую среду. Отмечается, что из-за особо сложных условий сбора разлитой нефти и ее производных на таких территориях (непроходимость для обычной техники, низкие температуры, высокая вязкость деградированной нефти и др.) технологии, которые применяются для сбора и удаления нефти с воды и суши, за редким исключением, не могут быть применены. Используемые в Российской Федерации технологии сбора и удаления разлитой нефти с болот энергозатратны, длительны, не щадят деятельный слой болота. Они заключаются в разделении территории разлива на участки рытьем траншей с прокладкой дорог, в соскребывании и смыве нефти в эти траншеи с последующим сбором остатков. Иногда участок загрязнения обрабатывается суспензией биопрепарата после удаления основной части нефти с дальнейшим регулярным орошением водой участка. Зарубежные способы очистки болот от нефти крайне длительны, дороги и основаны главным образом на использовании ручного труда. В таких условиях разработка технологии способа очистки болот от углеводородов имеет высокую актуальность. В статье предлагается современная высокоэффективная технология очистки болот от нефти со значительно лучшими технико-экономическими и экологическими характеристиками по сравнению с существующими.
Homeostatic plasticity in neuronal cultures from the YAC128 Huntington disease model mouse

Publisher: name: University of British Columbia

description: Huntington disease (HD) is an inherited neurodegenerative disorder caused by expansion of the CAG repeat region of the huntingtin (Htt) gene. Early in the disease neuronal degeneration is preceded by synaptic dysfunction and changes in cellular signaling. This includes reduced BDNF signaling and altered calcium homeostasis, which could interfere with the group of processes known as homeostatic plasticity which alter neuronal connectivity and excitability to maintain neuronal network stability. We compared neurons cultured from normal (wild-type) mice with those from mice expressing the human genomic DNA for mutant huntingtin (YAC128). We focused on synaptic scaling, the process whereby the strength of synapses onto a neuron changes based on its level of activity. This is typically measured using the amplitude and frequency of miniature excitatory postsynaptic currents (mEPSCs), which represent the response to neurotransmitter release from individual synaptic vesicles. We attempted to induce scaling at excitatory glutamatergic synapses in striatal projection neurons (SPNs) in cortico-striatal co-cultures, and in cortical pyramidal neurons (CPNs) in cortical mono-cultures, by suppressing activity with tetrodotoxin (TTX) or disinhibiting activity with bicuculline (BIC) over 48 hours. This failed to induce homeostatic plasticity in either wild-type or YAC128 SPNs; however, TTX did induce an increase in synaptic AMPA receptor content and glutamatergic synapse density in wild-type (WT) CPNs, which was reflected in increased mEPSC amplitude and frequency. In CPNs from YAC128 HD mice this occurred only after pre-treatment with pridopidine – a drug previously tested in HD clinical trials – or the sigma-1 receptor (S1R) agonist 3-PPP. These data, combined with the results of manipulating culture medium BDNF concentration in WT CPN cultures, led us to conclude that impairment and restoration of homeostatic plasticity in YAC128 CPNs depends on changes to multiple signaling pathways modulated by S1R, including BDNF signaling. These results suggest that cortical homeostatic plasticity at glutamatergic cortical synapses is disrupted early in HD and may play a role in the disease’s early cognitive and psychiatric symptoms. They also indicate that S1R agonists can ameliorate this disruption, adding to the evidence that drugs of this class may be of use in treating the early symptoms of HD.

description: The pairing symmetry of superconducting states is a critical topic in the realm of topological superconductivity. However, the pairing symmetry of the $A\mathrm{V_3Sb_5}$ family, wherein $A=\mathrm{K,Rb,Cs}$, remains indeterminate. To address this issue, we formulate an effective model on the kagome lattice to describe topological superconducting states featuring chiral charge density wave. Through this model, we explore the topological phase diagrams and thermal Hall conductivity under various parameters, with and without spin-orbit coupling. Our analysis reveals that the disparities in thermal Hall conductivity curves between different pairing symmetries are safeguarded by the topology resulting from the interplay of spin-orbital coupling and superconducting states. Remarkably, this theoretical prediction can potentially enable the differentiation of various superconducting pairing symmetries in materials via experimental measurements of thermal Hall conductivity curves.

Это самое южное проявление из установленных в Дагестане. Оно приурочено к предполагаемому поперечному (антикавказскому) разлому, по которому, вероятно, заложена долина р. Кара-Койсу. В статье приведены аналитические исследования, геолого-петрографическая характеристика и минеральный состав проявления. Последний характеризуется высоким содержанием цеолитов; вулканогенный материал представлен весьма легким пористым веществом, что позволяет говорить о принадлежности его к туфам. По химическому составу вулканокластический материал Гунибского проявления соответствует низкощелочным андезитам и дацитам. Установление эндогенных проявлений предполагает возможность распространения вулканогенного материала в зонах поперечных разломов и в других речных долинах территории, простирающихся вплоть до Главного Кавказского хребта, что в свою очередь расширит площади развития минерагении, перспективные на поисково-разведочные работы.

description: According to some models, there may be a significant population of radio pulsars in the Galactic center. In principle, a beam from one of these pulsars could pass close to the supermassive black hole (SMBH) at the center, be deflected, and be detected by Earth telescopes. Such a configuration would be an unprecedented probe of the properties of spacetime in the moderate- to strong-field regime of the SMBH. We present here background on the problem, and approximations for the probability of detection of such beams. We conclude that detection is marginally probable with current telescopes, but that telescopes that will be operating in the near future, with an appropriate multiyear observational program, will have a good chance of detecting a beam deflected by the SMBH.

description: The extragalactic magnetic field (EGMF) could be probed with $γ$-ray observations of distant sources. Primary very high energy (VHE) $γ$-rays from these sources absorb on extragalactic background light photons, and secondary electrons/positrons from the pair production acts create cascade $γ$-rays. These cascade $γ$-rays could be detected with space $γ$-ray telescopes such as Fermi-LAT. The $γ$-ray burst GRB 221009A was an exceptionally bright transient well suited for intergalactic $γ$-ray propagation studies. Using publicly-available Fermi-LAT data, we obtain upper limits on the spectrum of delayed emission from GRB 221009A during the time windows of 10, 30, and 90 days after the burst, and compare these with model spectra calculated for various EGMF strengths $B$, obtaining constraints on $B$. We show that the values of $B$ between 10^{-20} G and 10^{-18} G are excluded.

description: A Penrose diagram is constructed for a spatially coherent black hole that smoothly begins an accretion, then excretes symmetrically as measured by a distant observer, with the initial and final states described by a metric of Minkowski form. Coordinate curves on the diagram are computationally derived. Causal relationships between space-time regions are briefly discussed. The life cycle of the black hole demonstrably leaves asymptotic observers in an unaltered Minkowski space-time of uniform conformal scale.

Superconductivity of QCD vacuum in strong magnetic field

description: We show that in a sufficiently strong magnetic field the QCD vacuum may undergo a transition to a new phase where charged $ρ^\pm$ mesons are condensed. In this phase the vacuum behaves as an anisotropic inhomogeneous superconductor which supports superconductivity along the axis of the magnetic field. In the directions transverse to the magnetic field the superconductivity is absent. The magnetic-field-induced anisotropic superconductivity -- which is realized in the cold vacuum, i.e. at zero temperature and density -- is a consequence of a nonminimal coupling of the $ρ$ mesons to the electromagnetic field. The onset of the superconductivity of the charged $ρ^\pm$ mesons should also induce an inhomogeneous superfluidity of the neutral $ρ^0$ mesons. We also argue that due to simple kinematical reasons a strong enough magnetic field makes the lifetime of the $ρ$ mesons longer by closing the main channels of the strong decays of the $ρ$ mesons into charged pions.

description: Данное исследование посвящено истории становления и развития школ немцев, латышей, украинцев, поляков, евреев, проживающих в Башкортостане. В материалах рассматриваемого периода они отражены как западные народы. Использованы статистика и анализ земских органов, советских органов просвещения, содержание нормативных, партийных и правительственных документов, позволивших увидеть некоторые специфические особенности. Школы этих народов в 20–30-е гг. сохраняли определенную автономность и традиционные методы воспитания, несмотря на политизацию школы и унифицированную систему образования. В год подготовки к Всемирной фольклориаде в Башкортостане становится актуальным рассмотрение и освещение различных сторон жизни и деятельности многочисленных народов республики, в том числе не одно столетие проживающих здесь западных народов. В целом, история национального образования в 20–30-е гг. наиболее насыщенна и интересна, поэтому может быть полезной в плане гармонизации межнациональных отношений.

description: В статье рассматриваются общественно-политические взгляды и деятельность уральского областного руководителя здравоохранения И.С. Белостоцкого, который после восстановления советской власти на Урале летом 1919 г. становится первым заведующим Екатеринбургским отделом здравоохранения, а затем, с 1923 г. – заведующим Облздравотделом Уральской области. В статье дается оценка деятельности Ивана Степановича, показаны первые попытки реформирования системы здравоохранения на региональном уровне, делаются выводы о прямой связи между дореволюционным партийным стажем и развитием административной карьеры. Особо исследуется участие Белостоцкого в преодолении эпидемической заболеваемости в регионе, разработке проектов планов больничного и курортного строительства на Урале. В статье дается информация о судьбе И.С. Белостоцкого в 1920–1930-е гг., когда, несмотря на традиционные для того времени обвинения в троцкизме и вредительстве, ему удалось избежать уголовной ответственности.

description: Video streaming applications have newly attracted a large number of participants in a distribution network. Traditional client-server based video streaming solutions sustain precious bandwidth provision rate on the server. Recently, several P2P streaming systems have been organized to provide on-demand and live video streaming services on the wireless network at reduced server cost. Peer-to-Peer (P2P) computing is a new pattern to construct disseminated network applications. Typical error control techniques are not very well matched and on the other hand error prone channels has increased greatly for video transmission e.g., over wireless networks and IP. These two facts united together provided the essential motivation for the development of a new set of techniques (error concealment) capable of dealing with transmission errors in video systems. In this paper, we propose an flexible multiple description coding method named as Flexible Spatial-Temporal (FST) which improves error resilience in the sense of frame loss possibilities over independent paths. It introduces combination of both spatial and temporal concealment technique at the receiver and to conceal the lost frames more effectively. Experimental results show that, proposed approach attains reasonable quality of video performance over P2P wireless network.

description: The study was conducted to evaluate the implementation of teaching physics though plasma-
TV: the case of Mirab  Azerent  Berebare  Wereda in Lera and Mugo Secondary and
Preparatory Schools in grade 11th
. To achieve the objectives of the study, research questions
find  out the problem of implementation of teaching physics in plasma-TV by using the
response of respondents such as teachers, students, supervisors and school principals. Based
on this, the research employed both qualitatively and quantitatively (mixed approach),
because the data obtained from interview and open-ended questionnaires needed qualitative
analysis and the data obtained through close-ended questionnaire need quantifying.  The
research helped  valid information which was strengthening the power of putting genuine
solutions.  The data collected during the study were analyzed using Statistical Package for
Social Sciences (SPSS) version 16.0. Descriptive statistics were used comprise frequency
counts, percentages, means, SD. The results of this study indicated that the average interest
(68.35%)  to  teach physics with plasma-TV,  from    teachers and students result  the low
(63.95%) adaptation of activities that done by plasma teacher after the class in both schools,
low  availability of infrastructure  and man power in both  sample  schools according to my
observation and respondents result, insufficient integrated work done by classroom teachers
and  plasma-TV  teacher  according to teachers’  and  students result,  though the classroom
observation  inefficient consideration of  translation words  by classroom teachers.  It is
recommended that classroom teachers should improve and create the good  condition for
translate of the core idea of the lesson of teaching physics in plasma-TV, give them tutorials,
homework and group work. Therefore, the above mention plasma methods of teaching were
one way of teaching in the curriculum and the area either due to regular continuity or partial
continuity of plasma-TV.

description: Die heutigen standardisierten Druckvorstufenverfahren sind auf die optischen Eigenschaften der Normdruckfarben abgestimmt. Will man deren Mängel, nämlich die Schichtdickenabhängigkeit des Farbtones und die beschränkte Sättigung der Sekundärfarben, mindern, dann ist ein von den optischen Eigenschaften der Druckfarben unabhängiges Druckvorstufenverfahren Voraussetzung. Ein solches Verfahren wurde zwar anfangs der 80er Jahre entwickelt, fand aber damals keinen Widerhall. Ausgehend vom inzwischen veränderten Umfeld wird in einem Nachwort auf die nun zu erwartenden Forderungen und Einflüsse auf die Weiterentwicklung der Druckfarben hingewiesen..
