COOLING INTENSITY OF INVERSE SOLUBILITY POLYALKYLENE GLYKOL POLYMERS AND SOME RESULTS OF INVESTIGATIONS FOCUSED ON MINIMIZING DISTORTION OF METAL COMPONENTS
Authors: Kobasko Nikolai
Published: March 2017

Poly(Alkylene Glycol) polymers of inverse solubility (PAG) provide ideal uniform cooling for minimizing distortion and preventing crack formation during hardening machine components and tools. However, in spite of ideal cooling, from time to time, a big distortion takes place during hardening process. A reason for a big distortion development during hardening in PAG solutions is explained and an idea how to fix the problem is suggested. It is shown that at the end of cooling coating can be locally dissolved by a cold water flow creating local open area where martensite transformation starts first. Due to greater specific volume of martensite, it creates a big distortion. To solve the problem, one should interrupt cooling process or stop agitation before insulating coating is dissolved. To perform correctly proposed technology, cooling intensity of inverse solubility PAG polymers of 1–20 % were investigated on the basis of use of regular thermal condition theory. As a result, dimensionless effective numbers Kn were obtained for recipes development. A technique for solving the problem is proposed by author. Examples of calculations are provided.
CONSTRUCTION OF MINIMAX CONTROL FOR ALMOST CONSERVATIVE CONTROLLED DYNAMIC SYSTEMS WITH THE LIMITED PERTURBATIONS
Authors: Svyatovets Iryna
Published: March 2017

The problem is considered for constructing a minimax control for a linear stationary controlled dynamical almost conservative system (a conservative system with a weakly perturbed coefficient matrix) on which an unknown perturbation with bounded energy acts.

To find the solution of the Riccati equation, an approach is proposed according to which the matrix-solution is represented as a series expansion in a small parameter and the unknown components of this matrix are determined from an infinite system of matrix equations.

A necessary condition for the existence of a solution of the Riccati equation is formulated, as well as theorems on additive operations on definite parametric matrices. A condition is derived for estimating the parameter appearing in the Riccati equation.

An example of a solution of the minimax control problem for a gyroscopic system is given. The system of differential equations, which describes the motion of a rotor rotating at a constant angular velocity, is chosen as the basis.

Published: March 2017

The article presents the results of the development of the echolocation device for geophysical exploration at shallow depth. The principle of operation, block diagram and time diagrams of the echolocation device for geophysical exploration at shallow depths are outlined. The urgency of developing an echolocation device for geophysical exploration at shallow depth is revealed in the conditions of a lack of mineral resources, the need to replenish them with the help of discovering new deposits.

It is analyzed that under the action of a shock wave, multi-frequency harmonic damped seismic waves are excited to the earth's surface, the frequency band of which is 1-200 Hz.

When detonation generators are used to control the earth's crust, the duration of the impact pulse is on the order of one millisecond and the frequency range at 0.5 from the maximum amplitude of the echo signals is 20-400 Hz, which allows using higher-frequency harmonic components of echo signals to determine and classify the object at depth up to 100 m.

Echolocation device for geophysical exploration is intended for detection and primary classification of objects by their acoustic rigidity and can be used for geophysical exploration at shallow depths (up to 100.0 m).

Published: March 2017

Present work addresses technological properties of powder made from Jerusalem artichoke, formed by the method of drying with mixed supply of heat, compared to traditional convection. It is shown that polysaccharides in the composition of Jerusalem artichoke of MHS-drying undergo less crystallization and hence drying is carried out under milder conditions than these components during convection method. We established capacity for the dispersing of dried Jerusalem artichoke in a traditional ball mill depending on the duration, which makes it possible to obtain dried products for various technological purposes. We demonstrated a capacity to swell in the resulting powder made from Jerusalem artichoke, which predetermines the formation of advanced capillary-porous structure. Results of the tensometric method of studies revealed that the formed structure of powder made from Jerusalem artichoke of MHS-drying is characterized by small pores at temperature 50 °С and by 1.2...1.5 times larger – at 70 °С, which must be considered when they are rehydrated. We examined a complex of basic functional-technological properties of powder made from Jerusalem artichoke: coefficient of water absorption (CW), water-retaining (WRC), fat-retaining (FRC) and emulsifying capacities (EC). During mathematical processing of the results received, we obtained a conceptual model that describes a dependence of the comprehensive indicator of technological properties of powder made from Jerusalem artichoke (by the defined weight coefficients: for CW – 0.2; WRC – 0.2; FRC – 0.3; EC – 0.2) depending on the temperature of MHS-drying and dispersibility.
The stability analysis of separated feed ultrasonic milling
Authors: Zhang Yuemin , Zhao Bo , Wang Yuqing , Zhao Binbin
Published: March 2017

The full-discretization method introduced by Ding has high computational efficiency without loss of any numerical precision regardless of low and high radial depth of cut for the stability analysis of ordinary milling operation in time domain. Contrast to ordinary milling, it exists the separation phenomenon between each cutter tooth and the workpiece in feed ultrasonic milling operation. So before analyzing the system stability by the full-discretization method, the contact state between the cutter tooth and the workpiece should be made clear. In this paper, the trajectory method is proposed by the authors to judge the contact state between the cutter tooth and the workpiece. The stability analysis is developed for separated feed ultrasonic and ordinary end milling operations by the above methods and is validated via time domain simulations and experiments for both operations. The analyses show excellent agreement with both the time domain simulations and the experiments. Further, several end milling experiments were conducted that demonstrate the result ultrasonic vibration in feed direction can suppress chatter in machining operations.
Cracked modeling and vibration analysis of pipe with a part-through crack
Authors: Yu Zhihong , Zhang Laibin , Hu Jinqiu , Hu Jiashun
Published: March 2017

Pipeline is an important transportation facility in the oil and gas industries. But cracks inevitably appear in the pipe body due to various factors. Mechanical analysis of cracked pipe structures based on local flexibility has received increased attention in the last three decades. However, few reports exist on the local flexibility of pipes with an arbitrary angled crack. In this paper, the general solution of the local flexibility equations of a pipe with a part through-crack subjected to axial force, shearing force, and bending moment is deduced with respect to an arbitrary angled crack. The proposed equations consider the influence of the crack orientation on the local flexibility coefficient. An adaptive Simpson method is used to calculate the local flexibility coefficients of a cracked pipe. The results of testing by Naniwadekar’s and Authors’ are used to validate the proposed method. The results demonstrate that the proposed method is accurate for calculating local flexibility and can be applied for vibration analysis in a pipe-like structure.
Extending the modal incremental dynamic analysis method for structures equipped with viscoelastic dampers
Authors: Zafarkhah Elyar , Raissi Dehkordi Morteza
Published: March 2017

Viscoelastic (VE) dampers can be efficiently used for improving the seismic behavior of structures and also retrofitting of existing structures. Efficient nonlinear dynamic analysis methods like the Incremental Dynamic Analysis (IDA), especially the one which is based on Modal Pushover Analysis (MPA), which has proved especially popular among researchers, are required for analyzing the structures with dampers. As the IDA method is too complicated and time consuming, the MPA-based IDA method was introduced, a method which is fast and cost effective and the results are accurate enough to be utilized. Adoption of a static analysis in the procedure of MPA-based IDA method encourages the speculation that this method cannot be used for structures with dampers. This misconception has led to the fact that no one has ever used this method for structures with additional damping. In the present article, it is intended to present an approach to promote the applicability of the MPA-based IDA method for structures with VE dampers. The proposed approach is verified by the exact IDA method and validated by a numerical example. The results indicate the sufficient accuracy of the proposed technique, in which the MPA-based IDA is employed for structures with VE dampers.
Adaptive estimation of VMD modes number based on cross correlation coefficient
Authors: Yang Hongbai , Liu Shulin , Zhang Hongli
Published: March 2017

The variational mode decomposition (VMD) proposed recently is a kind of time-frequency signal analysis method. VMD has some advantages on signal decomposition such as high precision and noise robustness, but its serious shortcoming is that the number of modes (K) should be given in advance. And if the number is chosen inappropriately, VMD will lead to larger decomposition error. In this paper, the VMD method is introduced and the over- and under-segment characters of VMD are discussed. The cross correlation coefficients can express the similarity between the two signals. Cross correlation coefficients among VMD components and the original signal are used to judge whether over-segment takes place. As a result, the estimation method of VMD parameter K is proposed. Based on the method, the tri-harmonic signal and the vibration signals of ball bearings are analyzed in detail. The results show that the proposed method is feasible and effective.
A novel scheme on multi-channel mechanical fault signal diagnosis based on augmented quaternion singular spectrum analysis
Authors: Lv Yong , He Bo , Yi Cancan , Dang Zhang
Published: March 2017

In this paper, a novel multi-channel mechanical failure signal classification method based on augmented quaternion singular spectrum analysis (AQSSA) is proposed. Quaternion is used to couple four channels signal, and the quaternion trajectory matrixes can be developed as augmented quaternion matrix by using the feature of the quaternion. The singular value sequence including characteristic information can be extracted by quaternion singular value decomposition (QSVD) of the augmented trajectory matrix using its covariance matrix. The method of traditional singular spectrum analysis (SSA) can only analyze the single channel signal, however, AQSSA can fully use the correlation of multi-channel and reduce the loss of the effective information. Additionally, the main singular values are defined by some methods such as difference spectrum aimed, which has the limitation that major singular values can’t be obtained under the high background noise. Thus, a concept of partial mean of singular value sequence is proposed, and it can be set as the standard of evaluating the trend of singular value sequence. In order to testify the performance of the proposed method, the numerical simulation signal and the fault vibration signal of bearing are simultaneously adopted to verify its effectiveness. The results indicate that the effectiveness of mechanical fault classification by the proposed method is superior to the traditional SSA method and the method of permutation entropy.
Discrete approximate optimal vibration control for nonlinear vehicle active suspension
Authors: Han Shi-Yuan , Zhong Xiao-Fang , Chen Yue-Hui , Tang Gong-You
Published: March 2017

This paper presents the approximate optimal vibration control methodology for discrete nonlinear vehicle active suspension subject to persistent road disturbances. Based on a dynamic model of nonlinear vehicle active suspension and a linear exogenous system model of the persistent road disturbances, a nonlinear two-point boundary value (TPBV) problem is introduced. By introducing a sensitive parameter, the original TPBV problem is reformed as a series of TPBV problems without nonlinear items. A discrete approximate optimal vibration controller (DAOVC) can be obtained by solving a Riccati equation, Stein equation, and nonlinear compensation item, respectively. An iteration algorithm is designed to realize the computational realizability of DAOVC based on the control performance. It is demonstrated that the control performance of ride comfort, road holding ability, and suspension deflection under the DAOVC are much smaller than the ones under the classical feedforward and feedback optimal vibration controller (FFOVC) and open-loop vehicle suspension system.

Adaptive backstepping sliding mode control for heavy-weight airdrop operations
Authors: Liu Ri , Sun Xiuxia , Dong Wenhan , Guan Xuning
Published: March 2017

This paper proposes an adaptive backstepping sliding mode flight control method that is compatible with heavyweight cargo airdrop. The goal is to maintain the plane states during cargo extraction process, in the presence of uncertainties of both constant and time-varying types, as well as matched and unmatched types. A backstepping sliding mode flight control law with parameter adaptation is presented based on the plane-cargo dynamics in strict-feedback form. The control approach consists in having an adaptation law that approximates the disturbance and uncertain aerodynamic function, which is separated from the complex nonlinearities. Also, the adaptation algorithm with projection can bound the estimated function. This ensures the robustness of the controller against time-varying disturbance and uncertainty. The convergence performance and robustness property of the control law are proved by the Lyapunov theory. The control effect is evaluated on a transport plane performing a maximum load airdrop task in a number of simulation scenarios.

Authors: Lu Wei Te , Wang Yan , Zhang Chun Qin
Published: March 2017

This paper established a computational model for the aerodynamic noise of a high-speed train with 3-train formation including 3 bodies, 6 bogies, 2 windshields and 1 pantograph system. Based on Lighthill acoustic theory, this paper adopted large eddy simulation (LES) and FW-H model to conduct numerical simulation for the aerodynamic noise of high-speed trains and analyzed the distribution of aerodynamic flow behavior and noises of the whole train. Researched results showed that the main aerodynamic noise sources of high-speed trains were in pantograph, pantograph region, streamlined region of head train, bogies, bogie region, windshield region, air conditioning and other regions. Pantograph head, junction of upper arm and lower arm, and chassis region were main aerodynamic noise sources of pantograph. Compared with other 5 bogies, bogie at the first end of head train was main aerodynamic noise source. In addition, vortex shedding and fluid separation were main reasons for the aerodynamic noise of high-speed trains. When the high-speed train ran at the speed of 300 km/h and 400 km/h, the main energy of the whole train focused on the range of 1000 Hz-4000 Hz. Aerodynamic noises were broadband noises in the analyzed frequency domain. At the longitudinal observation point which was 25 m away from the center line of track and 25 m away from the nose tip of head train, the total noise sound pressure level reached up to maximum values 96.5 dBA and 101.4 dBA, respectively. Compared with inflow, wake flow had a greater influence on the aerodynamic noise around high-speed trains. The main radiation direction of pantograph aerodynamic noises was the left and right sides of pantograph head. In addition, the main radiation energy of pantograph aerodynamic noises was in mid-high frequency. In the part of high frequency, pantograph head made the greatest contribution to aerodynamic noises in the far field.

Published: March 2017

Advanced liver cancers and biliary cancers represent diseases with dismal prognosis because
of frequent local invasion and metastasis. Effective therapeutic agents for these cancers have
not been established. Oncolytic viruses (OVs) constitute a novel class of promising, selective anticancer
agents and recent studies have elucidated their unique features. Moreover, clinical trials are
demonstrating promising results. Numerous OVs are being tested in preclinical models of hepatocellular
carcinoma (HCC). The lead agent Pexa-Vec (pexastimogene devacirepvec, JX-594), a recombinant
Wyeth strain vaccinia virus, has demonstrated preliminary evidence of safety and efficacy for
HCC in clinical trials. Few other OVs have entered clinical testing. Relatively few preclinical studies
and clinical trials exist for biliary cancers. In this review, we introduce various approaches using
OVs to treat the intractable hepatobiliary cancers.
Redox Biotransformation and Delivery of Anthracycline Anticancer Antibiotics: How Interpretable Structure-activity Relationships of Lethality Using Electrophilicity and the London Formula for Dispersion Interaction Work
Authors: Pang Siu-Kwong
Published: March 2017

Background:

Quantum chemical methods and molecular mechanics approaches face a
lot of challenges in drug metabolism study because of either insufficient accuracy, huge computational
cost, or lack of clear molecular level pictures for building computational models. Low-cost
QSAR methods can often be carried out, even though molecular level pictures are not well defined;
however, they show difficulty in identifying the mechanisms of drug metabolism and delineating
the effects of chemical structures on drug toxicity because a certain amount of molecular descriptors
are difficult to be interpreted.

Objective:

In order to make a breakthrough of QSAR, mechanistically interpretable molecular descriptors
were used to correlate with biological activity to establish structure-activity plots. The biological
activity is the lethality of anthracycline anticancer antibiotics denoted as log LD50. The
mechanistically interpretable molecular descriptors include electrophilicity and the mathematical
function in the London formula for dispersion interaction.

Method:

The descriptors were calculated using quantum chemical methods.

Results:

The plots for electrophilicity, which is interpreted as redox reactivity of anthracyclines, can
describe oxidative degradation for detoxification and reductive bioactivation for toxicity induction.
The plots for the dispersion interaction function, which represents the attraction between anthracyclines
and biomolecules, can describe efflux from and influx into the target cells of toxicity. The
plots can also identify three structural scaffolds of anthracyclines that have different metabolic
pathways, resulting in their different toxicity behavior.

Conclusion:

This structure-dependent toxicity behavior revealed in the plots can provide perspectives
on drug design and drug metabolism study.

Neste artigo de revisão narrativa atualizam-se alguns conceitos de dor articular. A prevalência da dor articular aumenta com o avanço da idade, assim como os custos no tratamento das limitações e incapacidades. Compreender as diferenças entre dor aguda e dor crônica permite melhor abordagem das dores articulares, onde a primeira representa um sinal de alerta e a segunda é considerada uma patologia em si. As causas da cronificação da dor ainda são incertas, porém, alguns modelos são propostos e discutidos, como a sensibilização central por excesso de informação nociceptiva, seja esta de origem inflamatória, traumática ou outra. Em dores crônicas inflamatórias - como nas Artrites reumatoides – destaca-se a importância de iniciar o tratamento precoce de forma agressiva para inibir o processo inflamatório e as deformidades estruturais. Osteoartrites, embora sejam predominantemente descritas por suas alterações degenerativas nas articulações, têm atualmente reconhecida sua fase inflamatória inicial. A dor articular tende a ser abordada predominantemente sob o ponto de vista biomecânico e inflamatório, contudo, a ausência da abordagem do componente neuropática da dor crônica, nas fases iniciais, é uma das causas de elevados custos e de grandes deformidades articulares.  Finalmente aborda-se a importância do movimento e da educação do paciente com dor articular com base no modelo biopsicossocial de saúde e dor.Palavras-chave: Dor articular; Artrite reumatoide; Osteoartrite; Dor inflamatória e neuropáticaABSTRACTThis article is a joint pain update.

Multivariate analysis showed that sex and screen time activity were factors most dominantly affecting blood pressure.Conclusion: There is a correlation between body mass index with blood pressure. However, there is no correlation between physical activity with blood pressure.
Donor-Recipient Weight and Sex Mismatch and the Risk of Graft Loss in Renal Transplantation
Authors: Miller Amanda J. , Kiberd Bryce A. , Alwayn Ian P. , Odutayo Ayo , Tennankore Karthik K.
Published: March 2017

Background and objectives

Relatively smaller kidney donor to recipient size is proposed to result in higher graft loss due to nephron underdosing and hyperfiltration injury, but the potentially additive effect of sex and weight mismatch has not been explored in detail. The purpose of this study was to determine if concurrent donor and recipient absolute weight and sex mismatch was associated with graft loss in a cohort of deceased donor kidney transplant recipients.

Design, setting, participants, & measurements

The association of kidney donor and recipient absolute weight and sex difference with death-censored graft loss was explored using a cohort of United States deceased donor recipients between 2000 and 2014 through the Scientific Registry of Transplants Recipients. Donor-recipient sex pairings (male donor–male recipient; female donor–female recipient; male donor–female recipient; female donor–male recipient) were further stratified by donor and recipient absolute weight difference (>30 or 10–30 kg [donorrecipient] or <10 kg [donor=recipient]) resulting in 20 weight and sex pairings. Time to death-censored graft loss for each pairing was evaluated using multivariable Cox proportional hazards models adjusting for donor, immunologic, surgical, and recipient predictors of graft loss compared with the reference group of male donor–male recipients with no weight mismatch (<10 kg difference).

Results

Of 115,124 kidney transplant recipients, 21,261 developed death-censored graft failure (median graft survival time was 3.8 years; quartile 1 to 3, 0.0 to 14.8 years). After multivariable adjustment, the highest relative hazards for graft failure were observed for female recipients of male donor kidneys and male recipients of female donor kidneys in situations where the recipient was >30 kg larger than donor (hazard ratio, 1.50; 95% confidence interval, 1.32 to 1.70; hazard ratio, 1.35; 95% confidence interval, 1.25 to 1.45, respectively).

Conclusions

A concurrent mismatch in donor-recipient weight (donor<recipient) and donor-recipient sex is associated with a higher risk of death-censored graft loss in kidney transplantation.

El trabajo analiza lo que piensan las personas de edad avanzada en torno a los cambios climáticos de su localidad a partir de sus creencias religiosas, estilos de vida y su interacción social. Las preguntas que guían la investigación son: ¿Cómo se procesan los temores y las inseguridades que provoca la variabilidad climática entre los habitantes? ¿Cómo crean un ambiente de seguridad y una perspectiva hacia el futuro? El análisis detalla cuatro posturas: la evolucionista, la nostálgica, la conservadora y la resiliente, de donde se desprenden decisiones, acciones y formas de construir, narrar y darle significado a la relación del hombre con su entorno.
GOBERNAR A LA JUVENTUD VULNERABLE: UN ANÁLISIS DISCURSIVO DE LAS POLÍTICAS DE EMPLEO JUVENIL EN CHILE
Authors: Rivera-Aguilera Guillermo
Published: March 2017

El presente artículo se pregunta cómo se gobierna la juventud vulnerable desde los discursos de las políticas de empleo juvenil en Chile. Para esto se realiza un análisis de discurso que toma como referencia documentos públicos elaborados entre los años de 2008 a 2015. Los resultados dan cuenta de cuatro hilos discursivos que emergen de las políticas de empleo juvenil: a) el discurso de la equidad-inequidad; b) el discurso del capital humano; c) la figura del joven vulnerable; d) la figura del joven productivo. De acuerdo con el análisis basado en el enfoque de la gubernamentalidad se discute en torno a elementos de la política que prescriben formas de "conducir la conducta" de los jóvenes vulnerables para su inclusión al mercado del trabajo.

La dimensión fractal del teatro en el cine argentino contemporáneo: formas que se asemejan en diferentes escalas
Authors: Soria Carolina
Published: March 2017

O objetivo deste artigo é analisar o texto dramático Fractal. Una especulación científica (2000) - trabalho de criação coletiva escrito e dirigido por Rafael Spregelburd - no contexto de produção do teatro dos anos noventa no cinema argentino contemporâneo, considerando-o como uma articulação entre as duas formas de arte. Por um lado, porque condensa muito dos procedimentos utilizados no teatro da década de noventa que entranham uma determinada concepção de prática cênica, do processo de construção e da relação entre teatro e realidade que caracterizam especificamente o chamado teatro de desintegração (PELLETTIERI, 2000; RODRÍGUEZ, 2000). Tais procedimentos são a alienação e a preocupação com a linguagem, a desintegração da concepção tradicional do personagem, a interação, não defender uma tese realista e empregar elementos absurdos. Por outro lado, porque acreditamos que é um precedente chave do cinema que chamamos pós-dramático pela repetição, em outra escala, das operações narrativas e estruturais, o status dos personagens e a construção interativa ou efeito borboleta das cenas, elementos a serem discutidos no filme Viola (2012, Matías Piñeiro).
Cinema de Moçambique no pós-independência: uma trajetória
Authors: Lopes José de Sousa Miguel Miguel
Published: March 2017

Inicialmente, e a partir de uma metodologia apoiada na pesquisa bibliográfica, abordaremos um momento importante na cinematografia moçambicana que foi a criação do Instituto Nacional de Cinema (INC) e suas motivações. Em seguida, e em decorrência desta criação, analisaremos como o governo moçambicano procurou atrair talentos de várias nacionalidades para poderem ajudar a colocar em prática uma cinematografia moçambicana. Está em marcha a busca de um novo cinema para, em alguma medida, descolonizar as mentes. Esta cinematografia terá seu ponto forte na produção de documentários que tiveram o nome de Kuxa Kanema (literalmente “o nascimento do cinema”), filmes cujo objetivo era “registrar a imagem do povo e devolvê-la ao povo”. Salientaremos a criação da Associação Moçambicana de Cineastas, a AMOCINE, cujo objetivo é o de revitalizar a produção cinematográfica no país. Analisaremos também a criação do festival internacional de documentários “Dockanema”, um dos momentos mais significativos da arte cinematográfica nacional. Finalmente, abordaremos alguns dos problemas com que se defronta a Sétima Arte em Moçambique e algumas sugestões que poderão, em alguma medida, contribuir para romper com alguns constrangimentos com que ela se depara.
Filme-desvio: do planejamento às contradições
Authors: Lima Tatiana Hora Alves de
Published: March 2017

Partindo da noção de desvio, desenvolvido como método filosófico por Guy Debord no livro A sociedade do espetáculo e como técnica situacionista para a crítica da linguagem do espetáculo no ensaio Métodos e técnicas de desvio (escrito por Debord junto com Gil Wolman), propomos pensar o filme Brasília, contradições de uma cidade nova (1967), de Joaquim Pedro de Andrade, como um filme-desvio em relação ao curta-metragem Brasília, planejamento urbano (1964), de Fernando Coni Campos. O desvio, enquanto contrário de uma citação, segue na contramão da verdade oficial e destrói os sentidos propostos pela história dos vencedores. Em seu sentido mais profundo, o desvio incorpora a dialética na forma e convoca o passado como devir. Assim, confrontamos as diferentes imbricações entre tempo cinematográfico e tempo histórico apresentadas pelos filmes em questão, tendo em vista que em Brasília, planejamento urbano a nova capital tem origens míticas e é erguida acima da história, segundo os princípios da utopia modernista, enquanto em Brasília, contradições de uma cidade nova, que traz vários planos e princípios formais semelhantes aos do filme oficial para desviá-los, a cidade é re-historicizada a partir de uma crítica ao presente.
Guiné-Bissau: do cinema de Estado ao cinema fora do Estado
Authors: Cunha Paulo , Laranjeiro Catarina
Published: March 2017

O objetivo deste artigo é, olhando para o passado da Guiné-Bissau nas últimas cinco décadas, refletir sobre o papel do cinema na construção da sociedade, da nação e do Estado da Guiné-Bissau. Pretende-se fazer um ponto de situação em relação ao projeto inicial de Amílcar Cabral, líder histórico da luta de libertação, que tomava o cinema enquanto meio para a descolonização do gesto e para a emancipação do olhar. Neste percurso, começamos por reconhecer a importância e a influência de movimentos emancipatórios no cinema mundial, como o Terceiro Cinema ou o Nuevo Cine latino-americano, no processo de luta revolucionária dos guineenses contra o colonizador e, posteriormente, no consequente processo de construção de uma identidade ou cultura nacional. Num segundo momento, tentamos relacionar os planos de Amílcar Cabral para a consolidação de uma cinematografia nacional (Cinema de Estado) com o atual cenário cinematográfico no território em que não se vislumbra qualquer política pública para o setor (Cinema fora do Estado).
Cosmopoéticas da descolonização e do comum: inversão do olhar, retorno às origens e formas de relação com a terra nos cinemas africanos
Authors: Ribeiro Marcelo R. S.
Published: March 2017

Com base na hipótese de que a emergência histórica dos cinemas africanos e sua contemporaneidade são indissociáveis de uma reivindicação do direito de olhar, de narrar e de imaginar o mundo, este artigo busca estabelecer um quadro conceitual para uma história das formas de imaginação do comum nos cinemas africanos. Nessa história ainda a escrever, que pertence ao programa de pesquisa mais amplo de criação de um atlas de cosmopoéticas, é preciso reconhecer o sentido inaugural do gesto de inversão do olhar colonial, no contexto da emergência dos cinemas africanos entre as décadas de 1950 e 1960, e do retorno inventivo às origens, que torna possível a participação do cinema nos processos históricos que caracterizam a condição pós-colonial, nas décadas seguintes (consolidação de Estados nacionais, aspirações pan-africanistas, Négritude, internacionalismo revolucionário, cosmopolíticas do capital e dos direitos humanos, afropolitismo etc.). Dessa forma, é possível reconhecer a tarefa estética e política da descolonização como horizonte cosmopoético inaugural dos cinemas africanos, entre a inversão do olhar colonial e o retorno inventivo às origens, nos filmes Afrique sur Seine (Mamadou Sarr, Paulin Vieyra, 1955), Soleil Ô (Med Hondo, 1967) e Touki Bouki (Djibril Diop Mambéty, 1973). Em filmes mais recentes, como La vie sur terre (Abderrahmane Sissako, 1998), Terra sonâmbula (Teresa Prata, 2007) e Pumzi (Wanuri Kahiu, 2009), torna-se evidente uma tendência de deslocamento da cosmopoética da descolonização à cosmopoética do comum, associada ao tema da relação com a terra, em sua polissemia: terra pátria, terra natal, desterro, exílio, terra devastada.
Análise do documentário A Batalha de Adwa, de Haile Gerima: entre memória coletiva e símbolos nacionais etíopes
Authors: Berthet Marina Annie , Reyna Carlos
Published: March 2017

O documentário A Batalha de Adwa, realizado pelo cineasta Haile Gerima, permite o acesso a um fato da história etíope até então pouco conhecido pelo público brasileiro. Através de seu documentário, o cineasta etíope faz uma releitura desse fato histórico, propondo-se a retraçar seus aspectos marcantes e a entendê-los por meio de análise de fontes inovadoras, como entrevistas, canções e material iconográfico. Como qualquer obra fílmica, essa é repleta de representações e subjetividades que constituem os elementos necessários para a reconstituição de uma voz etíope sobre a história da batalha.
