Nonlinear Beamforming Based on Group-Sparsities of Periodograms for Phased Array Weather Radar
Authors: Kitahara Daichi , Kuroda Hiroki , Hirabayashi Akira , Yoshikawa Eiichi , Kikuchi Hiroshi , Ushio Tomoo
Published: March 2021

We propose nonlinear beamforming for phased array weather radars (PAWRs). Conventional beamforming is linear in the sense that a backscattered signal arriving from each elevation is reconstructed by a weighted sum of received signals, which can be seen as a linear transform for the received signals. For distributed targets such as raindrops, however, the number of scatterers is significantly large, differently from the case of point targets that are standard targets in array signal processing. Thus, the spatial resolution of the conventional linear beamforming is limited. To improve the spatial resolution, we exploit two characteristics of a periodogram of each backscattered signal from the distributed targets. The periodogram is a series of the powers of the discrete Fourier transform (DFT) coefficients of each backscattered signal and utilized as a nonparametric estimate of the power spectral density. Since each power spectral density is proportional to the Doppler frequency distribution, (i) major components of the periodogram are concentrated in the vicinity of the mean Doppler frequency, and (ii) frequency indices of the major components are similar between adjacent elevations. These are expressed as group-sparsities of the DFT coefficient matrix of the backscattered signals, and we propose to reconstruct the signals through convex optimization exploiting the group- parsities. We consider two optimization problems which evaluate the group-sparsities in slightly different ways, and both problems are solved with the alternating direction method of multipliers including nonlinear mappings. Simulations using real PAWR data show that the proposed method dramatically improves the spatial resolution.
Religião e intolerância aos homossexuais
Authors: ALCANTARA Naiara Sandi de Almeida
Published: March 2021

Este texto tiene como objetivo discutir la intolerancia política a nivel nacional utilizando la religión como una variable interviniente y los homosexuales como un grupo objetivo. Bueno, es una minoría que desde los años 90 comenzó a exigir públicamente y de manera más amplia los derechos sociales y políticos, y por eso dejó de ser un grupo oculto y se convirtió en un blanco de intolerancia. La metodología utilizada fue cuantitativa a través del análisis descriptivo y estadístico de las encuestas aplicadas por LAPOP, con el propósito de evaluar simultáneamente los efectos de la religiosidad individual y nacional. Partimos de dos hipótesis de investigación: i) la asistencia, en la práctica religiosa, puede ser un predictor de una mayor objeción a la participación del grupo minoritario investigado en la esfera política, y ii) aunque durante el período analizado (2006-2018) el Brasil ha sufrido una serie de cambios legislativos a favor de los derechos de los homosexuales, pero se cree que la población es en gran medida intolerante con este grupo. Por lo tanto, el objetivo es responder a la siguiente pregunta: ¿la manifestación de actitudes de intolerancia política hacia los homosexuales está condicionada por la religiosidad? Del análisis, se encontró que, de hecho, la frecuencia religiosa es un predictor de intolerancia, y que los más religiosos tienden a ser más intolerantes en todos los años analizados, sin embargo, los promedios de tolerancia son altos y están en un movimiento creciente.  Así como la legislación en el país se ha vuelto más tolerante, también lo han hecho los ciudadanos, al menos en relación con los homosexuales, según los datos.
A Universidade como peça de museu
Authors: SILVEIRA Ronie Alexsandro Teles da
Published: March 2021

A crise da universidade não pode ser devidamente compreendida sem vinculá-la à crise da razão. Por seu lado, os dispositivos da racionalidade científica atual compartilham princípios com as religiões monoteístas, das quais herdou o impulso original pela universalidade. Tal impulso orienta também as práticas políticas democráticas. Assim, a razão vincula-se à verdade e ao bem comum contra a opinião e o interesse individual. Feito esse mapeamento sintético dos elementos fundamentais da racionalidade, podemos compreender melhor a crise da universidade, cuja função é a educação racional. A universidade mostra-se impotente no interior de uma situação da qual não pode sair porque é a universidade. Assim, resta a ela somente aguardar que a decadência gradual a converta em uma peça de museu.

As comunidades remanescentes de quilombos e a luta pela regularização de suas terras.
Authors: PIRES João Henrique Souza , NOVAES Henrique Tahan
Published: March 2021

Como parte de un proyecto más amplio vinculado a nuestra investigación doctoral, el presente trabajo tiene como objetivo analizar la lucha de las comunidades quilombo restantes por el derecho adquirido con la aprobación del Artículo 68 de las Actas de las Disposiciones Constitucionales de Transición (ADCT). Cien años después de la abolición de la esclavitud, el artículo 68 reconoce por primera vez a las comunidades quilombolas restantes el derecho definitivo a poseer la tierra que ocupan. Sin embargo, a pesar del derecho adquirido y la lucha de las comunidades para regularizar y asegurar sus tierras, se observa que menos del 10% de las comunidades tienen sus tierras totalmente tituladas. En este sentido, a través del análisis bibliográfico y documental, buscamos analizar el proceso histórico que se desarrolla desde finales de la década de 1970 y continúa hasta nuestros días, particularmente la formación del Movimiento Negro Unificado (MNU), su participación en la lucha por la redemocratización del país, su desempeño en la Asamblea Nacional Constituyente (ANC), la aprobación del Artículo 68 como ADCT y la lucha de las comunidades quilombo restantes para hacer cumplir el derecho adquirido.
A trajetória da SENAES em prosa e números
Authors: CHIARIELLO Caio Luis
Published: March 2021

A Secretaria Nacional de Economia Solidária – SENAES - foi criada em 2003 e teve a missão de inserir a Economia Solidária na agenda pública e elaborar as políticas do Executivo para empreendimentos solidários e seu desenvolvimento no Brasil, articulada com outras instâncias governamentais. Neste artigo abordamos a trajetória da SENAES, suas principais linha de ação, bem como os Programas Temáticos e Ações Orçamentárias geridos pela Secretaria. A dinâmica do orçamento federal para a SENAES de 2004 a 2017 nos permitem inferir que houve uma consolidação das políticas públicas para a Economia Solidária seguida de seu desmonte paulatino, até a finalização das atividades da Secretaria em 2019, representando a interrupção de uma experiência de política pública direcionada para ação coletiva de trabalhadores e trabalhadoras.

RESGATE HISTÓRICO DA PRESIDÊNCIA DA SOBAMA: ASSOCIAÇÃO BRASILEIRA DE ATIVIDADE MOTORA ADAPTADA (2004 - 2007)
Authors: Mauerberg-deCastro Eliane
Published: March 2021

I was president of two consecutive terms of the board of directors of the Brazilian Society of Adapted Motor Activity (Sobama). I was, also, a founding member of its inauguration in 1994 at the University of São Paulo, and, throughout the years of Sobama, I realized we all were a small family comprised of friends and colleagues of an emerging area, the adapted physical education area. Inspired by Sobama’s previous leadership, our directive board represented a young generation of leaders around physical education adapted in Brazil, or “adapted motor activity,” terminology instituted at the foundation of the society. It is important to highlight that before the creation of Sobama, USP brought together academics and professionals in the area during the São Paulo State Symposium on Adapted Physical Education, which had its first edition in 1986 and then every two years until 1994. In this report I summarized the historical activities that occurred during the two terms of Sobama’s board of directors under my responsibility between 2004 and 2007.

Authors: Dr. Muhammad Zia-ur-Rehman  , Dr. Waseem Ishaque  , Rimsha Zafar
Published: March 2021

The current study focuses not only on developing leadership but also emphasizes the crucial role of employing the concept of followership effectively. The reason for this is that the leadership concept in the organization may not be effective without followership. Therefore, to obtain exemplary leadership, followership has to be inculcated, and that of courage embedded in it. The current study applied to reverse the lens approach in leadership and hypothesized the relation between courageous followership and exemplary leadership. The sample size of 255 was used for this research, chosen by employing convenience-sampling techniques due to Covid-19 conditions and restrictions. The data were screened and then using SPSS did analysis.  The results show that courageous followership had an impact on exemplary leadership, meaning that courageous followers would promote exemplary leadership practices in the organizations, which can be very useful for organizations to understand and promote.
Impact of University Climate on Teachers’ Morale in Public Sector Universities in Pakistan

Published: March 2021

An institution that works for individuals or is fretful with fulfilling the requirements of students may have a climate where the teachers sense an assured egotism and self-importance, have their place in that organization. Various factors are involved to get the highest competence and output from the teachers i.e. service safety, positive institutional climate, and good income. The self-confidence of professors and a positive university climate play an important role to give the students a quality education. This study identified the university atmosphere and examined the influence of the university environment on the confidence of professors. A mixed-methods approach was used to perform the study.  The initial seven plus ten declarations on the tool signify the exposed environment, and the preceding seven plus ten avowals represent the confined environment. A self-developed morale scale and face-to-face meetings were steered for data collection. The population of the study was 4210 teachers and 350 heads of departments in Punjab province. The sample was 35 leaders, 255 male and 171 female teachers from public sector universities in Punjab, using proportional, and stratified random sampling techniques. Tested the readability test of the revisions with participants, the null hypotheses were tested. Both data were analyzed with quantitative and qualitative analytical tools that followed the content analysis technique. The results showed that most public sector universities in Pakistan have an open climate like a closed university climate. However, it was found that noteworthy variance existed in the ethical level of teachers working in open and closed atmospheres.
Freedom and Desire: A Quest for Spiritual Journey in James Joyce’s Novel Ulysses/A Portrait of the Artist as a Young Man
Authors: Muhammad Bilal  , Nasim Ullah Khan  , Syed Qasim Shah
Published: March 2021

This study, Freedom, and Desire: A quest for a spiritual journey in the novel by James Joyce, describes the journey of the main character of the story from his adolescence to the best way of conceptualizing the dynamic, multilateral relationship between individual experience and socio-cultural scope, since it recognizes the causal significance of culture but also recognizes individual choice and changes. The researcher examines the true desire which enables him to embrace his creative spirits “the actual experiences” which also symbolize freedom. This claim is formed by contemplating how many historical shifts in the socio-cultural context, i.e. the increase in freedom of choice, the shift in interpersonal patterns, the loss of traditional values, the loss of religious understanding, and the increasing conflict between the desire for individuality and the complexity of achieving it, have led to changes in the essence of true intentions and modern personhood. For this research, a qualitative method is adopted in the framework of Locke on Freedom (2015). It also points out and aims at the need to establish a new perspective on the provision of spiritual treatment in the field of freedom and desire, which focuses on improving the particular spiritual journey of the person, rather than simply reassuring spiritual distress. A man should not have to restrict himself to limited ideas, for this one has to go beyond limitation to change his mind which is the ultimate reality of advancement in life.

Authors: Tauqeer Hussain Hakro  , Khalid Hussain Abbasi  , Hakim Ali Mahesar
Published: March 2021

The primary objective of this study was to investigate the influence of organizational culture, supervisor behavior, and HRM practices over the employee turnover intentions of the NGOs sector in Sindh, Pakistan. A questionnaire survey, adopted from prior studies for data collection was used to carry out current research. The questionnaire was based on close-ended questions, having a seven-point Likert-type scale. The convenient sampling (an item of non-probability sampling) was used to collect data. A total of 180 questionnaires were distributed among employees of the NGOs sector, out of which 121 questionnaires were considered fit for data analysis and further interpretations. Initially, the data was processed in SPSS version 22.0 for analyzing descriptive statistics, whereas, the model was tested in SEM Smart-PLS. The organizational culture, supervisor behavior, and HRM practices were the significant predictors to reduce employee turnover intentions. While HRM practices and supervisor behavior contribute to decreasing employee turnover intentions. Furthermore, this study explained the interconnection of various factors such as, organizational culture, supervisor behavior, and HRM practices that cause employee turnover intentions, which were realized by actual employee turnover. The investigation provided explanations about why NGO employees intend to quit. Referring to empirical findings of current research, it is highly likely that NGOs might be able to reduce employee turnover. This research addressed specific circumstances of NGOs that cause high employee turnover, particularly in Sindh, which may be generalized at the country level.

A NOVEL PEPTIDE MODULATOR OF THE HUMAN CHANNEL NAV1.5 FROM LATRODECTUS TREDECIMGUTTATUS SPIDER VENOM
Authors: Shynykul Zhanserik Shynykul Zhanserik
Published: March 2021

Spider venom contains a wide repertoire of pharmacologically active compounds, and in the case of some spider species bite, toxins from spider venom can play a fatal role for humans as well as other organisms. Among all the spiders, one could say the bite of Latrodectus tredecimguttatus, known as Black Widow spider, is very dangerous and can even lead to tragic consequences. Especially, voltage-gated sodium channels are responsible for propagating action potentials in excitable cells. NaV1.5 plays a crucial role in the human cardiac muscle, where it enhances the influx of sodium ions via the cell membrane, causing the fast depolarization phase of the cardiac action potential. It is also an important therapeutic target for heart disorders. Various venom-derived peptides have been observed as potential modulators of sodium channels, and these biologically active peptides are an abundant source for pharmacological tools.

Published: March 2021

Background: Preterm birth is considered as the main cause neonatal mortality and morbidity[1]. The rate of preterm birth ranges from 5% to 18% of babies born in different countries[2].However, prevent, predict and delay this health condition is almost unsuccessful[2]. Millions of babies are born preterm and this number is rising[2]. Infectious diseases and local and systematic inflammation is most contributing factor to multifactorial etiology of this health condition[3]. The pregnant women are more susceptible to periodontal disease as it is the most prevalent chronic infectious disease in adult population[4]. There are 57 health condition related to periodontitis[5].The physical and hormonal alternation make the pregnant women more vulnerable to the periodontal disease. Relatively high prevalence of periodontitis during pregnancy found in different population, especially socio-economically disadvantaged women[4]. Periodontitis found to be a risk indicator for preterm birth outcome[6].Clinical trails were conducted to assess the effect of periodontal treatment during pregnancy on reducing these outcomes[7-25].

Objective: To assess the effect of different periodontal interventions during pregnancy on preterm birth outcome.

Methods: A systematic review was conducted according to PRISMA guidelines[26], searching Cochrane Library, Pubmed and Embase databases up to 10 December, 2020. PICOS (Population, Intervention, Comparison and Outcomes, study design) framework was used as a search strategy tool. Intervention include scaling and root planning (SRP), Control oral hygiene instructions (OHI), Inclusion criteria were studied in pregnant women, including randomized controlled trials with the aim of assessing the effect of any periodontal treatments on preterm birth outcomes. Main outcome was perform birth(<37 gestational week). The data were extracted from two authors and statistical analyses carried out using Review Manager (RevMan).

IR spectra of samples were recorded in the range 600—4000 cm-1 and subjected to and principal component analysis (PCA) which allowed to clearly identify 5 clusters in the scores plot using the third and the second principal components, corresponding to the brands of tablets. For Paracetamol and Caffeine-sodium benzoate tablets the combination of IR spectroscopy and PCA was able to recognize the manufacturer on the basis of distance between samples in clusters in the PCA scores plot.
SYNTHESIS OF NEURAL NETWORK ALGORITHMS FOR CLASSIFICATION OF MARINE OBJECTS IN LOW-FREQUENCY PASSIVE SONAR SYSTEMS
Authors: Andreev O.A. , Trofimov A.T.
Published: March 2021

The paper addresses the issue of insuring the required probability of correct classification of marine objects in low-frequency passive sonar systems. The solution to the issue is sought through the application of methods for the synthesis of neural network classification algorithms using poly-Gaussian probabilistic models (Gaussian mixture models, GMM). It is shown that the use of GMM makes it possible to solve a number of problems specific to the issue; classification algorithms synthesized using mentioned methods can be implemented in the form of neural networks, which in turn can be described in C++/VHDL to create endpoint computing devices or software systems. The results of modeling of synthesized classification algorithms on experimental data are presented; it is demonstrated that such algorithms make it possible to increase the probability of correct classification of marine objects and to satisfy typical requirements for classification systems in low-frequency passive sonar systems.

Published: March 2021

USACE’s IWR must responsibly manage its work packages through its Operations and Maintenance (O&M) annual budget. IWR has developed several models that use data to inform investment strategies for the prioritization of work packages; however, these strategies are based on old data and not predictive in nature. Because work package ranks significantly change when applying a Value Model and Monte Carlo simulation, this research focuses on the significance of a 3-year predictive budgeting model; a model which is enabled by the National Defense Authorization Act (NDAA, 2020). This research will demonstrate a forward-looking methodology using a Value to Consequence Ratio metric (VCR) for funding work packages through a decision support interface via Microsoft’s Power BI. This paper presents the framework for USACE’s Civil Works Navigation business line and creates the potential for future work to integrate other business lines utilizing System Dynamics.
Prüfkonzept zur Untersuchung des Dauerstandverhaltens von textilbewehrtem Beton/Testing concept for the investigation of the long-term durability of textile reinforced concrete
Authors: Rempel Sergej , Spelter Arne , Hegger Josef , Will Norbert
Published: March 2021

Zur Sicherstellung der Tragfähigkeit innerhalb der Lebensdauer von Bauteilen sind neben der Bemessung für Kurzzeitbelastungen auch ausreichende Kenntnisse zum Dauerstandverhalten erforderlich. Dies gilt insbesondere auch für den Textilbeton, der im Vergleich zu Stahlbeton eine deutlich längere Lebensdauer aufweisen soll. Das Dauerstandverhalten wird in der Regel durch die Dauerstandfestigkeit der verwendeten Werkstoffe charakterisiert, die unter anderem durch die Spannung, die Temperatur, die Feuchtigkeit und den pH-Wert (Alkalität) beeinflusst wird. Zur Untersuchung des Dauerstandverhaltens von textilbewehrtem Beton existieren zum aktuellen Zeitpunkt keine Prüfnormen. Im ersten Teil des Beitrags wird auf der Basis vorhandener Regelwerke und Prüfkonzepte für FVK-Bewehrungen, zu denen Untersuchungen zum Kriechverhalten, zur Alkaliresistenz und Dauerstandfestigkeit existieren, ein Prüfkonzept für den Textilbeton abgeleitet. Damit wird im zweiten Teil ein Versuchsaufbau vorgestellt und ein Vorschlag zum erforderlichen Prüfumfang zur Ermittlung der Dauerstandfestigkeit von Textilbeton gemacht. Mit den Ergebnissen soll die innerhalb der geplanten Nutzungsdauer eines Bauteils ansetzbare Textilspannung festgelegt werden.
Ermittlung der dynamischen Kennwerte von Eisenbahnbrücken unter Anwendung von unterschiedlichen Schwingungsanregungsmethoden
Authors: Bruschetini-Ambro Sebastian-Zoran , Fink Josef , Lachinger Stefan , Reiterer Michael
Published: March 2021

Zur Ermittlung der dynamischen Kennwerte von Eisenbahnbrücken wurden in den letzten 20 Jahren in Österreich vorwiegend die ambiente Schwingungsanregung, die Analyse des zeitlichen Ausschwingens nach Zugüberfahrt und die Impulsanregung mit einem Sandsack oder Ähnlichem angewendet. Bei der Anwendung dieser unterschiedlichen Schwingungsanregungsmethoden zeigte sich, dass insbesondere die Werte für die Strukturdämpfung sehr stark streuen und nicht immer reproduzierbar sind. Die Vergleichbarkeit von Erst- und Folgemessungen sowie die von unterschiedlichen Büros durchgeführten Messungen ist hier oftmals nicht gegeben. Im vorliegenden Artikel wird ergänzend zu den angeführten üblichen Methoden zur Ermittlung der dynamischen Kennwerte die erst im letzten Jahr systematisch bei einer Vielzahl von Eisenbahnbrücken angewendete krafterregte Schwingungsanregungsmethode vorgestellt. In den Jahren 2016 und 2017 wurden bei insgesamt 20 Eisenbahnbrücken unterschiedlichen Typs sowohl die oben genannten üblichen als auch krafterregte Schwingungsanregungen mit bis zu vier parallel geschalteten mobilen Long Stroke Shakern sowie einem mechanischen Unwuchterreger durchgeführt. Die erzielten Messergebnisse werden dargelegt und es wird ein Vergleich der mit den unterschiedlichen Schwingungsanregungsmethoden erzielten Ergebnisse für die dynamischen Kennwerte durchgeführt. Es zeigt sich, dass die krafterregte Schwingungsanregungsmethode für die Ermittlung der Eigenfrequenzen und insbesondere der Lehr´schen Dämpfung von Eisenbahnbrücken zu äußerst zuverlässigen, wenig streuenden und reproduzierbaren Ergebnissen führt. Die Lehr´schen Dämpfungen ergeben insbesondere bei Rahmentragwerken wesentlich höhere Werte verglichen mit den Vorgabewerten der derzeit gültigen Normen.
A'ingae =sa'ne 'APPR' and the semantic typology of apprehensional adjuncts
Authors: AnderBois Scott , Dąbkowski Maksymilian
Published: March 2021

We explore the semantics and typology of functional morphemes encoding apprehensional, i.e. negative prospective, meanings through a detailed case study of the adjunct uses of =sa'ne 'APPR' in A'ingae (or Cofán, ISO 639-3: con, an Amazonian isolate). We provide one of the first formal accounts of apprehension: In a structure [p [q=sa'ne]], =sa'ne 'APPR' encodes a modal semantics where the goal worlds of the actor responsible for p avoid a salient situation r=>q. Finally, we reveal two inherent asymmetries among apprehensional functions (precautioning asymmetry and timitive asymmetry), thus making substantial predictions with regards to typological patterns in apprehensional morphology.
Revisiting Olga, the beautiful dancer: An intersective A-analysis
Authors: Maienborn Claudia
Published: March 2021

The paper presents a novel semantic account of the so-called "intersective/non-intersective" ambiguity of structures such as beautiful dancer. The proposal contrasts with Larson's (1998) famous N-analysis in taking the adjective as the ambiguity trigger and in unmasking the bracketing paradox perception of the non-intersective reading as a grammatical illusion. The adjective has no compositional access to the verbal root's event argument but is always linked to the referential argument of the noun. -er nominals are analyzed as a special kind of role noun (such as king, guest, judge). They introduce a social role r that manifests itself via the verbal root's e-argument. (However, neither r nor e are compositionally active.) An evaluative adjective such as beautiful introduces an underspecified trope variable, which calls for a pragmatic specification of the adjectival predicate's ultimate target. A general pragmatic parsimony condition ensures that referents introduced by linguistic material are chosen as best target candidates whenever possible. The -er nominal's social role r is an ideal choice in this respect. The linking of the adjective to the verbal root's e-argument is mediated via r and thus a secondary pragmatic effect. The proposal provides a unified analysis for modified -er nominals (beautiful dancer) and other instances of role- and event-related interpretations for adnominal modification such as, e.g., just king.
Situation types in complementation: Oromo attitude predication
Authors: Bryant Shannon , Bhadra Diti
Published: March 2021

Though languages show rich variation in the clausal embedding strategies employed in attitude reports, most mainstream formal semantic theories of attitudes assume that the clausal complement of an attitude verb contributes at least a proposition to the semantics. The goal of this paper is to contribute to the growing cross-linguistic perspective of attitudes by providing semantic analyses for the two embedding strategies found with attitude verbs in Oromo (Cushitic): verbal nominalization, and embedding under akka 'as'. We argue that Oromo exemplifies a system in which non-speech attitudes uniformly embed situations rather than propositions, thereby expanding the empirical landscape of attitude reports in two ways: (i) situations and propositions are both ontological primitives used by languages in the construction of attitude reports, and (ii) attitude verbs in languages like Oromo do the semantic heavy lifting, contributing the "proposition" to propositional attitudes.

This paper explores cross-linguistic differences in the pragmatic con- straints governing the use of subject-oriented honorific verb forms in Japanese and in three varieties of Yaeyaman (Southern Ryukyuan). I show that plural subjects with mixed honorific status give rise to different felicity patterns in these language varieties, and argue that these differences arise from different rankings of competing pragmatic constraints.

Introdução: Acretismo é a implantação da placenta anormal na parede uterina, é classificada segundo o grau de profundidade. A incidência de acretismo aumentou no mundo todo em paralelo ao aumento de cesáreas, ocorrendo 1 caso para cada 533 partos. Objetivo: Avaliar a intervenção cirúrgica cesárea/histerectomia (placenta in loco) como resolução saudável binômio materno-fetal. Método: Série de casos. Discussão: A melhor proposta terapêutica nos casos de acretismo é o planejamento de parto cesárea seguido de histerectomia total abdominal (HTA). O tratamento conservador (manutenção do útero deixando a placenta in situ) pela elevada morbi-mortalidade associada deve ser encarado de forma excepcional. Os perfis das pacientes dos casos se enquadram nos fatores de risco citados nos estudos. Todos os casos possuíam cesárea anterior e diagnóstica de placenta prévia; média de idade: 36,8 anos (32-41 anos); média de paridade (gesta): 2,8 (G4-G2). Desta forma, vamos ao encontro com o que a literatura cita como os principais fatores de risco. O caso 2 foi programado parto cesariano e HTA. Porém, durante cesárea preservou o útero e evoluiu para choque hemorrágico após 4 horas do término do procedimento, sendo necessário HTA em 2º tempo. Nos casos 1, 3 e 4 foi planejado parto cesárea e HTA, sem intercorrências. Em todos os casos o tratamento final evoluiu com histerectomia, indo ao encontro da literatura como melhor terapêutica. Considerações finais: Uma boa conduta diante do acretismo com diagnóstico prévio através USG e Doppler, planejamento de parto em centro de referência (reserva de hemoconcentrados e UTI) com equipe experiente e multidisciplinar tem o poder de mudar o prognóstico.

A mastalgia é responsável por 60% a 70% das consultas no dia a dia do consultório de um mastologista. Pode ser classificada em cíclica e acíclica. O diagnóstico é clínico. Exames de mamografia e ultrassonografia devem ser solicitados conforme a idade da paciente e os achados de exame físico. O tratamento não medicamentoso com medidas comportamentais promove alívio em 80% das pacientes. Anti-inflamatórios não esteroidais e o tamoxifeno devem ser utilizados nos casos de sintomatologia intensa.

Thermally expanded graphite (TEG) is one of the best precursors for receiving of plane nano-dimensional particles. Crucible graphite of Taigin deposit was used as a basic material to receive TEG. It is established that repeated thermo-chemical, as well as additional mechanical TEG dispersion does not lead to formation of nano-dimensional graphite particles. In order to receive graphite particles with several nano-meters of thickness, TEG was treated by ultra-sound dispersion in four liquid mediums. Different influence of chosen liquid mediums on the process of ultra-sound dispersion of TEG particles is conditioned by peculiarities of liquids’ behavior in cavitation process, it is described integrally by a notion “erosion activity”. Erosion activity, in the first turn, depends on the superficial tension. The quantity of the received broken material is defined by the depth of penetration of the liquid into the body volume, which depends on liquid wettability. The used liquids: water, acetone, benzene and toluene had different polarity and superficial tension that allowed to put into reality different physical and chemical effects at TEG dispersion. Benzene has the lowest meaning of superficial tension, it moistens the graphite surface very well and penetrates easily into its micropores. Despite of the relatively low erosion capacity, non-polar organic liquids, penetrating to the big depth into the graphite particle’s volume are capable to provoke a visible breaking influence at ultra-sound dispersion on inner graphite structures and its breakage into plates. The best results of breakage are reached at use of benzene that has zero molecule polarity and the best wettability of graphite surface. At ultra-sound dispersion in all environments, plane graphite particles are received that are several dozens of nano-meters thick. However, some particles broken in ultra-sound have visible fluctuations from ideal plane form and can form complicated spatial figures of irregular structure. The received results may be a base for creation of a method for receiving of thin graphite plates with geometrical parameters that are necessary for making of composites and objects of nano-techniques.

The existing practice of designing heat exchangers is based on the application of an engineering method of calculation, the so-called graphical method. Therefore, the design principle of the method consists in solving a system of nonlinear equations describing the heat exchange between coolants composed of various organic substances toluene, benzene, using the method of successive approximations, and the number of approximations can be very large. Randomly given by a number of unknown quantities, namely the temperatures of the pipe walls and some structural dimensions of the apparatus, which are further specified when performing the calculations, are specified. A graph is plotted for the specific heat fluxes for both fluids from the assumed temperatures of the pipe wall, and the lines, the so-called load characteristics of the heat exchanger, are drawn through the points obtained. The analysis of the conditions of application of the load characteristics of the heat exchanger when calculating the surface of the apparatus for the three main types of heat exchange, implemented in heat exchangers: boilers, condensers, cooler-heaters in which heat transfer occurs between various organic liquids under various conditions of their work. It is shown that the load characteristics of heat exchangers are non-linear depending on the specific heat flux on the pipe wall temperature, and the curvature of the line deviations from the straight line depends on the type of heat exchange and the flow of coolants, the curvature of the lines is close to the straight line dependence in the laminar mode, significantly different from the straight line in the transition mode and turbulent regimes and is very different from the straight line dependence on heat exchange with a change in the state of aggregation of both fluids. A direct calculation of the surface of the apparatus has been proposed, a technique has been developed for determining the temperature of the pipe wall, selections of initial conditions for performing calculations, step-by-step changes in the magnitudes of the driving forces are recommended when performing approximations, which reduces the time spent on the calculation. The paper also analyzes the choice of changes in the magnitudes of the driving force of the heat transfer process for the number of approximations, shows the intervals of variation of this quantity at which the calculation error decreases. Direct determination of the surface of the device significantly increases the accuracy of the calculation of the surface.

The interaction between 1,3-dioxolane with primary aromatic amine- sulfanilamide (streptocide), secondary aromatic amine-N-benzylaniline and also with amine of heterocyclic series – 4-aminopyridine. It is found that, sulfanilamide (streptocide), which has an electron withdrawing sulfonamide group in para position, reacts with 1,3-dioxolane in an atmosphere of benzol and trifluoroacetic acid producing 3-(4-sulfamoylphenyl)-3,4-dihydroquinazoline-6-sulphonamide, that is corresponding to the previous result obtained when 1,3-dioxolane reacts with para-nitroaniline (which also contains electron-withdrawing nitrogroup) resulting in 3-(p-nitrophenyl)-6-nitro-3,4-dihydroquinazoline. Under the same conditions the interaction between 1,3-dioxolane and N-benzylaniline results in producing 4,4'-bis(phenylmethyleneamino)diphenylmethane, which refers to a different class of compounds – diphenylmethane derivative. A primary amine of heterocyclic series 4-aminopyridine reacts with 1,3-dioxolane in the presence of concentrated hydrochloric acid producing N,Nʹ-di-(4-pyridinyl)methylenediamine. Antimicrobic properties of received compounds were studied on museum potentially pathogenic microorganism strains: Staphylococcusaureus (strain 906), Candid aalbicans (АТСС 24433), in FSBI «Scientific Centre for Expert Evaluation of Medicinal Products» of the Ministry of Health of the Russian Federation. Only N,Nʹ-di-(4-pyridyl)methylenediamine out of three investigated compounds showed microbiological activity. This compound inhibits growth of Staphylococcus aureus at concentration 62.5 µg/ml, culture death comes from the effect of concentration 125.0 µg/ml. The morphology of compounds was established according to mass spectrometry data, 1Н NMR spectroscopy, the structure of N,Nʹ-di-(4-pyridyl)methylenediamine in the form of chloride was proved using X-ray structural analysis.
