(Neo)modernism în rupturi rizomice
Authors:   “Bogdan Petriceicu-Hasdeu” Institute of Romanian Philology, Republic of Moldova, Burlacu Alexandru
Published: August 2021

This article exposes theses on the Eminescian model as the irradiating center of the Romanian literary canon. The poetry of the 60s and 80s of Bessarabia is conceived as ,rupture with the dogmas of socialist realism and a return to the models Arghezi, Blaga, Bacovia, Barbu. Neomodernism, through rhysome ruptures, has a decisive impact on the metamorphoses of sixty/seventy poetry. The testing of aesthetics produces a change in the concept of poeticity, a mutation from the ardent east-ethics of the generation of Grigore Vieru and Liviu Damian to the aesthetic „liberated from sentimentality”, to the poetry of the imaginary, of the virtual worlds, of poetic models. Neomodernism, very eclectic in its essential moments, is adapted to the intrinsic tradiționalism of the poetry 60s and 80s and has a decisiv impact in the metamorphoses of the transition from modernism to postmodernism.
O familie model şi rezonanţa ei în comunitate
Authors:   “Bogdan Petriceicu-Hasdeu” Institute of Romanian Philology, Republic of Moldova, Colac Tudor
Published: August 2021

Ethnographic studies have revealed the importance of the family in the development of popular culture among Romanians, highlighting its role in transmitting old creative traditions in art and its wide receptivity to innovations in current work technique. In this context, the author concludes that the family presents itself as a constant in the process of shaping the culture and civilization of a people, but also as a source of values that is continuously implemented in the reality of community and individual life. Its appearance is the result of a long and complex process, which has its beginning in the early stages of the development of the family as a social unit. In the present approach, the author discusses a family of musicians, who became a model for the locals of Costiceni village, revealing the spiritual values of resonance that it generated over the years to the rural community from which it draws its roots. Insisting on the spiritual side, he will demonstrate how this social constant has survived and how over the years it has become a generative example of culture and civilization in the genuine environment, thanks to its functions: ethical, educational, psychological, political, legal and religious.

Hasdeu’s interest for autochthon mythology found its embodiment in a series of investigations folklore, where discussion were proposed more assertions, opinions, research issues of spirituality Dacian. The autochthon mythology in its modern expression is based on the traditions, revealing ways of artistic transfiguration of reality in terms of visions and representations that characterizes the creative personality of the Romanian people. The archetype of Dochia that returns repeatedly is a hypothetical model, is an emblematic symbol of a sacred space circumscribed aspects of its fundamental values. Dochia is the personification of the ancient Gauls, it symbolizes in the acceptation of B. P. Hașdeu historical setting of the Romanians, but also a fall in natural springs descriptive saw the size of the imagination Dacian, closely related to the same myth of steadiness.

Las múltiples vidas del sistema de partidos en Argentina
Authors: Varetto Carlos Augusto
Published: August 2021

El libro contribuye al conocimiento de la dimensión funcional del sistema partidario argentino; en la cual pueden encontrarse claramente diferenciadas dos “vidas”, fases o subsistemas, las que a su vez habría que sumar al resto de los subsistemas que surgen cuando se abordan la dimensión horizontal y vertical de los sistemas partidarios en contextos de estados multinivel. Es en estas “dimensiones” o “arenas” donde se definen los variados tipos de interacciones entre los partidos políticos y en donde dichas interacciones se encuentran condicionadas a su vez por la presencia de múltiples escenarios sociales políticos y culturales. Es aquí entonces donde los partidos compiten dando lugar a subsistemas diferentes.
Al nacer la Patria
Authors: Tamagno Sánchez Mario
Published: August 2021

Hasta 1817 la revolución argentina permaneció estacionada en sus fronteras, demasiado lejos de los centros que representaban las dos causas que se disputaban el predominio de Sudamérica: Colonia o Independencia. Ni el virrey del Perú podía llegar a Buenos Aires ni los patriotas alcanzaban a amenazar a Lima. La inspiración afortunada de San Martín rompe el estancamiento y complementa la revolución argentina. Su Plan Continental puede sintetizarse así: cruzar los Andes, dominar el mar con una escuadra y desembarcar con un ejército cerca de Lima. Tres jornadas gigantescas.
Evaluation of the operational viability of forensic units in Brazil: A hybrid approach based on the BWM and R-TOPSIS
Authors: Rodrigues Flávio Leite , Júnior João Florêncio da Costa , Souza Ricardo Pires de
Published: August 2021

Public security is an area of increasing importance in Brazil, as society requires that public resources are managed more efficiently and effectively. Criminalistics is an integral and vital part of the Brazilian public security system and requires new management tools to optimize human resources, equipment, and facilities allocation. Faced with a challenging scenario of budgetary constraints in several areas in public administration, the search for innovative methods should be a priority for the forensic service sector managers. The current article presents a multicriteria decision model to evaluate the operational viability of 23 forensic units within the Federal Police of Brazil (PF). The framework used the hybrid approach BWM and R-TOPSIS. The proposed model led to the complete ranking of 23 local forensic units. Amongst the last positions in the ranking, it was possible to recommend merging or shutting down some units. The sensitivity analysis performed did not show abrupt variations in the original positions, confirming the robustness of the proposed solution. It was concluded that the model allowed resources optimization whilst not compromising the quality of the services provided to society.
On ranking by using weighted self-normalizing distance metrics in multi-attribute decision-making
Authors: Souissi Mohamed , Hafdhi Sana
Published: August 2021

Preliminary normalization is central to the decision process of several popular, recent or completely new multi-attribute decision-making (MADM) methods. However, a number of authors have pointed out serious pitfalls attributed to normalization methods. One major pitfall, which has been identified, is that normalization methods may lead to different final rankings of alternatives when a ranking procedure (RP) based on them is used for solving a MADM problem. The current paper aims to ascertain and illustrate the effectiveness of some RPs based on prominent primary WEighted Self-NORmalizing Distance (WESNORD) metrics and their averages. The effectiveness of the selected RPs is demonstrated by solving a logistics service provider (LSP) selection problem taken from the literature. The results reveal that the RPs considered deliver final rankings of alternatives, which are very similar to the SAW-produced reference ranking.

Published: August 2021

The purpose of this study is to examine influence of trade deficit and external debt on performance of economy of Pakistan during 1980- 2017. GDP is used as dependent variables while trade deficit, gross capital formation, exchange rate, labor force, manufacturing value added and total external debt are used as explanatory variable. The short-run, long-run association and stationarity of data amongst variables are obtained by applying vector error correction technique and Johansen Co-integration test. The study reveals that there is a statically important and negative influence of the trade deficit on GDP while total external debt also has a harmful impact on GDP. Moreover, results show that there is an optimistic and noteworthy connection among gross capital formation and GDP and Gross domestic product is positively influenced by Exchange rate, labor force and manufacturing value added. The association between total external debt and gross domestic product is negative and significant, it means when total external debit increases gross domestic product decrease. Government of Pakistan should create persistent strategies marked at differentiating economic actions so as to give nation prosperous sources of budget financing instead of trusting much on external borrowings.
Human immune globulin 10% with recombinant human Hyaluronidase-
A Review
Authors: Pervin Sneha , Ghosh Somsubhra , Bose Sankhadip , Sarkar Nandan
Published: August 2021

Primary immunodeficiency disorder (PID) refers to a heterogeneous cluster of over 350 syndromes that upshot from defects in the immune system development or function. PIDs are broadly classified as disorders of adaptive immunity or innate immunity. The enhanced efficacy of human immune serum globulin 10% with recombinant human Hyaluronidase with comparison to blood vessel human gamma globulin is a very prospective open-label study for PID. Treatment of primary immunological disorder diseases (PIDD) with Subcutaneous(SC) infusions of immune gamma globulin headed by an injection of hyazyme to extend SC tissue porousness was evaluated in two consecutive, prospective, non-controlled, multi-center studies. HYQVIA could be a subcutaneously mediated medication to treat the primary immunological disorder in adults. ENHANZE® drug delivery technology relies on the proprietary rHuPH20 macromolecule that facilitates the SC delivery of co administered medical specialty. Recombinant Human Hyaluronidase works by degrading the glycosaminoglycan hyaluronan, which plays a role in resistance to excessive flow of fluid within the Subcutaneous matrix, limiting massive volume SC drug delivery, dispersion, and absorption. Co-administration of recombinant Hyazyme with partner therapies can overcome administration time and volume barriers associated with existing SC therapeutic formulations.

Sulfur (S) is usually the second most accumulated nutrient in seeds of Cruciferae plant species such as the radish. Tropical soils have low S availability creating a challenge to manage plant nutrition and balanced plant development to produce high-quality seeds. This study evaluated the influence of S doses and organic compost fertilization on the content and accumulation of macronutrients in radish seeds. Eight treatments were studied in subdivided plots, where the presence (50 t ha-1) or absence of organic compost was placed in the main plot, and the S doses (0, 60, 120, 180 kg ha-1 of S) were placed in the subplots. A randomized block design with six replications was used. Seed dry weight, N, P, K, Ca, Mg, and S concentration (g kg-1 of dry matter), and the accumulation of nutrients in seeds (g plant-1) were evaluated. There was no significant effect of S doses, or organic compost, on the contents of macronutrients in radish seeds. When organic compost was not applied, great doses of S generated great dry weight and accumulation of macronutrients in the radish seeds. However, the application of organic compost increased the dry weight and the accumulation of all macronutrients in radish seeds in low S doses (up to 66 kg ha-1). Also, the presence of organic compost increased the dry weight and the concentration of macronutrients in radish seeds. The decreasing order of macronutrient content and accumulation by the radish seeds was: N > S > K > P > Ca > Mg.

БРОНЗОВЫЕ ЗЕРКАЛА ИЗ ТАЛЬХИРА КАК ИСТОЧНИК ПО МАТЕРИАЛЬНОЙ КУЛЬТУРЕ: ИССЛЕДОВАНИЯ И.И. КОПЫЛОВА
Authors: Мухтарова Гульмира Раиловна , Железняков Борис Анатольевич , Жумай Гульмира
Published: August 2021

Публикация основана на архивных материалах И.И. Копылова о месте и условиях находки бронзовых зеркал, данных анализов о составе металла. Проводится анализ опубликованных ранее данных по бронзовым зеркалам, происходящих из городища Талгар. Тем самым, на основе архивных данных исследователя средневекового памятника, ставится и во многом решается вопрос о местном производстве зеркал на местном же сырье. Ранее опубликованные статьи фактически ставили вопрос только об этнокультурной принадлежности орнаментального сюжета, из которого состоит рельефно-орнаментированная тыльная сторона зеркала, то есть ‑ о культурных истоках, распространенных в то время на Великом Шелковом пути орнаментов. Детали обнаружения зеркал в культурном слое, принадлежности руин построек крайне важны для реконструкции культурных контактов, а главное, для понимания высокого уровня развития ремесла на Талгаре в XI – первой половине XIII в., роли и месте ювелира и торевта в ремесленной «табели о рангах» Тальхиза, чьи богатые жилища и развитые производства располагались в центре города. Приводятся некоторые данные о сопровождающих находки зеркал в мастерских: массовых артефактах, орудиях, штампах.
НОВЫЕ МАТЕРИАЛЫ ДРЕВНЕГО АРХЕОЛОГИЧЕСКОГО КОМПЛЕКСА КАРГАЛИНСКОГО ИСТОРИКО-ГЕОГРАФИЧЕСКОГО МИКРОРАЙОНА

Published: August 2021

В статье систематизированы материалы древних археологических памятников Каргалинского историко-географического микрорайона (водный бассейн р. Узын-Каргалы) северных склонов Заилийского/Иле Алатау. Как правило, поселения древних земледельцев располагались в устье, на выходе горных ущелий и предгорной равнине. В бронзовом веке они устраивались близ головных водозаборов каналов и арыков. В раннем железном веке они строили оросительные системы на расстоянии до 20 км от гор, применяя акведуки. Скотоводы раннего железного века осваивали горные ущелья и плато микрорайона как под сезонные стоянки, так и под стационарные поселения. Древние погребальные памятники расположены в основном на возвышенностях у выходов из горных ущелий. В горной зоне они сконцентрированы на склонах горной гряды Майтобе и по левому берегу реки Узын-Каргалы в районе ущелья Жылысай. Наиболее ярким памятником региона считается каргалинское захоронение раннего железного века, где в 1939 г. обнаружен известный «Каргалинский клад», местоположение которого до сих пор оставалось неясным. По итогам исследований оно определено в 500 м вглубь от входа ущелья Ерменсай под объектом, условно называемым «Каргалинский камень – Каратас». Уникальный погребальный комплекс представляет собой массивный скальный блок, который использовался как монументальная надмогильная конструкция. Зафиксированный вещевой материал позволяет идентифицировать его как место известного каргалинского захоронения. Данный факт позволяет представить необычную традицию погребальной практики населения региона усуньского периода раннего железного века.

Published: August 2021

O objetivo deste artigo é apresentar a modelagem e a identificação de parâmetros dinâmicos de máquinas síncronas de pequena potência, tal como aquelas empregadas em nano e pico-aproveitamentos hidrelétricos. Inicialmente, no domínio do tempo, o comportamento dinâmico do Gerador Síncrono (GS) é analisado de forma a obter um modelo baseado em coordenadas dq0. Uma vez definido o circuito equivalente da máquina, é realizada uma análise no domínio da frequência para se obter o modelo de pequenos sinais que serve de base para o teste de resposta em frequência com rotor em repouso (SSFR, do inglês Standstill Frequency Response). Assim, é relatada uma aplicação do teste em um GS de 5 kVA, propondo uma abordagem onde são medidas apenas duas funções de transferência do modelo de pequenos sinais e fazendo uso dos testes clássicos de máquinas síncronas para melhorar os resultados. Os parâmetros obtidos são simulados e comparados com a máquina real.

Published: August 2021

O setor de distribuição de energia elétrica brasileiro é caracterizado por ser um monopólio natural. Como forma de reproduzir o funcionamento de um mercado competitivo, a Agência Nacional de Energia Elétrica (ANEEL) define indicadores de continuidade do serviço individuais e coletivos. Para esses indicadores, são estabelecidos limites por meio de uma metodologia de análise comparativa entre distribuidoras, que consiste na formação de clusters, com conjuntos de unidades consumidoras (UC) que possuam atributos semelhantes. Tais atributos são extraídos da Base de Dados Geográfica das Distribuidoras (BDGD) e de outras bases de dados. Nesse contexto, este trabalho tem como objetivo apresentar uma ferramenta para a determinação dos atributos provenientes da BDGD. A ferramenta consiste na utilização do software de mapeamento QGIS para extração dos atributos. Os dados são organizados em uma planilha do software Excel e servirão de base para estudos de avaliação de novos atributos para a metodologia de análise comparativa.

Published: August 2021

O Brasil possui um dos maiores sistemas de transmissão do mundo. Dentro deste sistema, os transformadores de potência correspondem a cerca de 60% do custo total das subestações de alta tensão. Neste contexto, este artigo tem como objetivo propor uma metodologia para analisar os custos da indisponibilidade desses transformadores de potência devido ao envelhecimento adicional causado aos demais equipamentos ao suprir sua demanda. Os resultados mostram que o custo da indisponibilidade é consideravelmente maior quando da ocorrência de desligamentos programados. Ressalta-se que 5 transformadores estudados são responsáveis por 93% do custo de indisponibilidade, e o fato em comum entre estes é a média de carregamento normal estar acima de 50%. Perante estes achados, conclui-se que a metodologia é capaz de auxiliar na tomada de decisão relacionada à gestão destes equipamentos que podem ser considerados críticos devido ao seu alto custo de indisponibilidade, acarretando consequências econômicas significativas no longo prazo.

Published: August 2021

Este trabalho propõe um método de interconexão de fontes renováveis, possibilitando, neste caso, o desenvolvimento de sistemas híbridos de geração de energia elétrica. O gerenciamento do fluxo de potência entre as fontes primárias de geração é realizado através do conversor isolado bidirecional Push-Pull. O sistema emprega uma fonte primária CC, sendo, neste caso, um sistema fotovoltaico (PV), associado a uma geração em corrente alternada (CA) composta de gerador de indução auto excitado (GIAE) e um compensador síncrono estático de distribuição (DSTATCOM), além de contar com um banco de baterias para armazenamento (ESS) do excedente não consumido. De modo geral, existem dois barramentos em corrente contínua (CC), sendo o primário e o secundário do conversor Push-Pull. Neste artigo, dá-se ênfase no modo elevador do Push-Pull, ou seja, na injeção da energia disposta no barramento primário, a qual pode ser oriunda tanto da geração fotovoltaica quanto do banco de baterias, no barramento CC do DSTATCOM. A modelagem matemática do conversor Push-Pull é realizada considerando a modulação PWM simétrica, a partir da qual projeta-se os controladores. Por fim, resultados de simulação validam o modelo e os controladores projetados.

Permanent Magnet Synchronous Motors (PMSMs) may present spatial harmonics depending on the design guidelines or imprecisions on the manufacturing process. The interaction of conventional sinusoidal current feeding strategies with these spatial harmonics can produce a considerable torque ripple. This paper deals with a modified Finite Control-Set Model Predictive Torque Control (FCS-MPTC) loop as an active torque ripple minimization solution for PMSMs with spatial harmonics. The proposed approach designs a novel cost function, based on the cross product reactive instantaneous power theory. The benefits of the proposed generalized approach include providing smooth torque production and the Maximum Torque per Ampère (MTPA) operation on PMSMs with a number of spatial harmonic sources, including those on zero-sequence. The effectiveness of the presented control strategy is demonstrated comparatively to conventional sinusoidal current feeding strategy on a PMSM drive employing a three-phase four-leg two level voltage source inverter under both steady and transient state.

High electromagnetic forces on power transformers windings may cause the equipment unavailability, resulting in technical and financial losses. To ensure its reliability, transformers must withstand the mechanical stresses demanded by the operation conditions. Once forces measurement and determination have a high degree of complexity, it is needed tools that support forces calculation and analysis accurately. This paper presents the Finite Element Analysis (FEA) applied to determine the electromagnetic forces and its distribution on transformer windings. A complete and close to the practice modeling is done, considering the magnetic core and lateral phases presence in a 3D and 3-phase configuration. The total, radial and axial forces over the windings, as well as its distribution around the core column and along its height are determined on the three phases. With precision and versatility, FEA may be widely applied by industry, contributing for more reliable transformers designs and in cost reduction.

This paper is focused on a comparison between two linear matrix inequality conditions for design of robust state feedback controllers applied for current regulation of gridconnected converters with LCL filters, operating under uncertain grid impedance at the point of common coupling. The first condition is the well known quadratic stability and the second one is the polyquadratic stability, which uses extra matrix variables. It is shown that the condition with slack variables can provide superior performance in terms of ensuring stable and suitable operation for a larger set of uncertainties.

Published: August 2021

The use of air conditioning is growing up very much in Brazil and in the world in general. That is no longer a luxury, but a necessity, though they have heavy impacts on the consumption of electricity. The alignment between the peak thermal load and the highest solar incidence of solar energy leads the scientific community to search for machines powered by this type of energy. Energy costs are higher when the solar energy is decreasing so recommending a more powerful storage of energy. Regarding this point of view, soil is one of the oldest, universal and most extensive form of thermal energy storage. This paper shows how thermal energy storage can be used to provide air conditioning at very low costs. A simple technology is dicussed showing that it is possible to store energy underground and recover it in a very efficient way to provide thermal comfort.

De acordo com os pesos ξ das céluas x e sua posição j (ξx,j), o inversor pode gerar até 15 níveis na tensão de saída. A configuração da topologia diminui o número de fontes de tensão isoladas necessárias para a obtenção da quantidade de níveis desejada. O inversor funciona com a modulação staircase, baseada na eliminação de harmônicos. A topologia apresenta baixa distorção harmônica e poucos interruptores eletrônicos quando comparada com o conversor multinível convencional para entregar a mesma quantidade de níveis na tensão de saída. Estudos teóricos e resultados em simulação são apresentados a fim de validar o conversor proposto.

Authors: Adnan Asmadi
Published: August 2021

Kajian ini bertujuan untuk mengkaji/menganalisis penyusunan metode dan formulasi pemilihan dan penetapan lokasi penataan kembali permukiman kumuh dengan konsolidasi tanah vertikal (KTV) di perkotaan berdasarkan berbagai faktor utama, penunjang dan subfaktornya, baik dari aspek kebijakan pemerintah, masyarakat maupun aspek lingkungan, serta mengimplementasikannya untuk menghitung nilai skoring potensial dalam rangka menentukan skala prioritas penanganan/pembangunannya. Pendekatan kajian menggunakan studi kebijakan dan pustaka melalui eksploratif dan empiris dengan metode dasar kuantitatif dan kualitatif, yang didukung studi lapangan di 5 kota besar sampel. Hasil kajian berhasil menyusun/membangun suatu metode/formulasi penghitungan nilai skoring pemilihan calon lokasi konsolidasi tanah vertikal sesuai nilai potensialnya melalui pembobotan, skala dan skoring terhadap faktor/subfaktornya, yang hasilnya dibagi 3 kelompok kriteria potensi berdasarkan total nilai skor (TNS), yaitu TNS ≥3,00-4,00; TNS 2,00-<3,00; dan TNS <2,00. Hasil penghitungan menggunakan formulasi tersebut diperoleh calon lokasi RW sampel di setiap kota sampel, namun skornya masih jauh dari nilai maksimalnya (100%), sehingga masih sangat sulit diimplementasikan, terutama sangat rendahnya dukungan persetujuan masyarakat sebagai calon peserta dibandingkan ketentuan peraturan yang menginsyaratkan setuju minimal 60% pemilik tanah yang meliputi 60% dari luas seluruh arealnya.

Currently, the regulation regarding Water Resources is regulated in Law Number 17 of 2019 concerning Water Resources (“SDA Law”), and several provisions have been amended by Law Number 11 of 2021 concerning Job Creation (“Job Creation Law”). The existence of water resources, which is the constitutional right of every Indonesian citizen, is fundamental. Water should be the right of every layer of Indonesian citizens because the 1945 Constitution guarantees constitutional rights. Therefore, water must be controlled by the State and used as much as possible for the prosperity of the people. Based on Article 33 paragraph (2) and paragraph (3), Utilization of Water Resources can contextualize the paradigm of control over water resources between the Natural Resources Law, the Job Creation Law and its derivative regulations must prioritize the management of water resources with a state responsibility approach (State control) that prioritizes the interests of the State. Social needs (living needs of the people) and community involvement in planning for exploitation, protection, and financing of the benefits of irrigation have not yet detailed regulations regarding the use of water for the benefit of other industries.
