Os gestos da montagem nas artes audiovisuais: Ensino-aprendizagem dentre as estéticas do banco-de-dados
Authors: Szafir Milena
Published: February 2019

O presente ensaio verbal é a tentativa de um relato reflexivo desde um remix de trechos da tese de doutorado Retóricas Audiovisuais 2.1 – Ensino e Aprendizagem Compartilhada: Passado, Presente, Futuro ou Por uma Arqueologia-Cartografia da Montagem (2011-2015). Antes de ser defendida, uma prévia dos oito capítulos – com foco no quinto layer (camada) Techné: Jogos e Desafios – foi enviada e apresentada em congresso da USP sobre educação na graduação (25-27 de maio de 2015), então sob o título Metodologia 'Aprendizagem Compartilhada': pesquisa e ensino por uma educação criadora. Ser professora, para mim, é compreender diariamente que o caminhar do (auto-)conhecimento é infinito – i.e. educação é um processo ininterrupto da formação do ser humano –, que a docência é uma aprendizagem compartilhada profundamente enriquecedora, que as universidades públicas (pesquisa, sala de aula e sociedade/extensão) são extremamente necessárias em nosso país e que a carreira acadêmico-universitária é de uma vida cotidianamente desafiadora e potencialmente gratificante para o desenvolvimento pessoal e coletivo.

Inicialmente um projeto didático sob demanda – experimentações tecno-conceituais do open source “ImageJ” (Visualzing Vertov) frente à metodologia dos gestos de montagem nas estéticas do banco-de-dados –, “Stream'engramas de uma revolução” (2014-2016) transformou-se em uma (con)textual leitura áudio-visual – artística e experimental – de nossa tese de doutorado (2011-2015). Através das fórmulas da paixão que engramatizam nossas memórias em intenso streaming tele-audiovisual, tal projetar pedagógico tornou-se, em si, uma virtual série cartográfica e arqueológica das gestualidades imago-ensaísticas dos vídeos-remix em comunhão aos motion graphics (Retóricas Audiovisuais 2.1).Assim, no dia 21 de novembro de 2016 realizamos a avant-premiere de “Stream'engramas de uma revolução” junto a um pequeno, e seleto, grupo de amigxs próximxs – entre curadorxs, pesquisadorxs e intelectuais. Ao compartilharmos tal postagem através do Vimeo – “#streamengramas de uma revolução .77b” (cor, 4mins.) –, solicitamos aos convidados que gerassem feedbacks por escrito (auxiliando-nos naquele work-in-progress).
A imagem e as figurações do sensível na obra de Miguel Rio Branco
Authors: Ulhôa Marco Túlio
Published: February 2019

O artigo analisa o curta-metragem Nada Levarei Quando Morrer, Aqueles que a mim Deve Cobrarei no Inferno (1985), do fotógrafo e artista plástico, Miguel Rio Branco. Ao retratar a dimensão simbólica do espaço público e dos aspectos da vida social do bairro do Maciel, na região do Pelourinho, em Salvador, a obra de Miguel Rio Branco realiza, através da construção de um regime de visibilidade condicionado pela imagem fotográfica e cinematográfica, uma penetração nas questões ontológicas que caracterizam a relação entre a dinâmica histórica – como exercício de escrita da memória e manutenção do discurso religioso – e a inscrição de uma ordem profana produzida por meio dos excessos evidentes na figuração dos corpos, da violência e do erotismo. Para isso, aborda-se a opção do artista pelos elementos estéticos da arte barroca, como traço histórico e mitológico de uma genealogia cultural e de um discurso de resistência próprios à comunidade retratada.

Hans Schleif
Authors: Julian Klein
Published: February 2019

Among the members of the Archaeological Institute of the German Reich, the architectural historian Hans Schleif was notable for the extent of his involvement with the crimes of the National Socialist regime. His achievements in scientific research, for instance as director of excavations at Olympia, are overshadowed by his career in the SS. He was director of the Excavation Department of the »Ahnenerbe« (ancestral heritage) of the SS. After the German invasion of Poland he was briefly appointed Custodian of German Cultural Assets based in Posnan. In 1943, he joined the SS Head Office for Economic and Administrative Affairs and rose to the position of deputy to C Group (Construction) director, Dr. Hans Kammler, whose permanent representative in the Jäger- und Rüstungsstab task force he became. In this role, Schleif was responsible above all for moving key arms production facilities underground, where fighter planes and the »reprisal weapons« V1 and V2 were built – hence for the largely subterranean concentration and slave labour camps of the Sonderstab Kammler. His grand- son, the actor Matthias Neukirch, created a theatre production about Schleif in collaboration with stage director Julian Klein at the Deutsches Theater Berlin. This text is a result of the research undertaken for the production, and reports on selected stages in Schleif’s biography.
Tensions in Islamic Economics
Authors: Mariyani Edward
Published: February 2019

The discipline of modern Islamic economics is currently torn in opposing directions by different visions of what its nature should be. On one side, it is argued that modern Islamic economics is too heavily influenced by secular economic theory. On the other side, it is argued that an overreliance on theologically-informed ideals would render Islamic economics unduly unrealistic. This paper explores the two competing criticisms of modern Islamic economics, illustrating how the conflict is played out in the area of Islamic banking. A case is tentatively made for greater pluralism in modern Islamic economics as a means of moving the discipline forward.

Este artigo, apoiando-se nas contribuições avançadas pela Sociolinguística no que respeita ao estudo do léxico na sua variação no tempo e no espaço, pretende analisar as variantes lexicais, obtidas in loco por meio do Questionário Semântico-Lexical (QSL) do Projeto Atlas Linguístico do Brasil (ALiB), nas localidades de Cuiabá (Brasil) e Covilhã (Portugal), correlacionando-as aos fatores extralinguísticos gênero, faixa etária, nível de escolaridade e naturalidade dos informantes. O principal objetivo consiste na identificação de possíveis mudanças linguísticas em curso, bem como, determinar a ocorrência de mudanças em progresso ou variação estável, de acordo com a Sociolinguística Variacionista de William Labov. Os resultados da análise sociolinguística apontam, de modo geral, para dois caminhos distintos trilhados pelas variantes: a estabilidade e a coexistência das variantes no sistema e a mudança em progresso.
DETERMINANTES DO ACESSO AO CRÉDITO RURAL VIA COOPERATIVAS DE CRÉDITO E BANCOS: UMA ANÁLISE DO CENSO AGROPECUÁRIO 2006
Authors: Schuntzemberger Amanda Massaneira de Souza , Sampaio Armando Vaz
Published: February 2019

A maioria das redes financeiras brasileiras, principalmente os bancos, ainda não prioriza as regiões periféricas, sobretudo no meio rural, perpetuando-se as limitações no acesso ao crédito. Nesse contexto, as cooperativas de crédito, na lógica de finanças de proximidade, podem ajudar a resolver algumas das imperfeições de mercado que existem no setor de crédito rural, uma vez que podem reduzir os custos de transação e a assimetria de informações entre os agentes. Desse modo, usando microdados do Censo Agropecuário 2006 do IBGE, um modelo logit multinomial verifica os fatores determinantes do acesso ao crédito rural via cooperativas de crédito e via bancos, em relação aos estabelecimentos agropecuários que não acessaram crédito, controlando por características tanto dos estabelecimentos agropecuários como de seus responsáveis. De modo geral, os resultados do modelo logit multinomial sugerem que, dentre as variáveis consideradas, dada a magnitude dos coeficientes, os estabelecimentos que tinham acesso à assistência técnica e cujo responsável participava de cooperativas e/ou outras entidade de classe tinham mais chances de acessar crédito rural via cooperativas de crédito e via bancos do que sofrer restrição de crédito.

Correlation test of maternal serum feritin with cord blood dopamine concentration had p value = 0,301 (p>0,05). In this study, we can conclude that there is no correlation between maternal serum feritin with cord blood dopamine concentration.Further research is needed by considering various factors that affect maternal ferritin concentration such as food intake and iron supplementation, and which affect dopamine concentration, such as stress and adequate sleep.
Instrument-based detection methods for adulteration in spice and spice products – A review
Authors: C Anandharamakrishnan S K V Bharathi, A Sukitha, J A Moses,
Published: February 2019

Spices play an important role as flavorants, colorants, preservatives and bioactive compounds in medical, food and cosmetic applications. India is the spice bowl of the world and spice production is scattered across the country. Almost every stage of production, including cultivation, harvest, handling, storage, transportation and distribution has impact on spice quality. Adulterants are often intentionally added to fetch better market value through inferior/ unacceptable quality products. Adulterants are a concern to quality, market compliancy and food safety. Over the years, several approaches for quantitative and qualitative detection of adulterants have been developed. Though basic and simple testing methods are available to detect the presence of adulterants, instrument based techniques are often adapted to detect the adulterants quantitatively. The objective of this work is to present a detailed note on these approaches with emphasis on the various analytical techniques used in the detection and quantification of adulterants in spice and spice products.
Development of diagnostic assays for rapid and sensitive detection of Phytophthora infecting major spices and plantation crops
Authors: C N Biju, S Sasi R T P Pandian, A I Bhat,
Published: February 2019

Phytophthora, the ubiquitous stramenopile phytopathogen is a major threat to several economically important horticultural crops including spices and plantation crops. Trans-seasonal survival of Phytophthora in plant debris and soil continuum has considerable epidemiological significance as the quiescent propagules often serve as primary foci of infection with inherent potential to trigger epiphytotics in the succeeding season favoured by conducive environmental conditions. Hence, early and rapid detection of over summering propagules is highly imperative to manage Phytophthora induced diseases efficiently and economically. Twelve isolates representing different species of Phytophthora (P. capsici, P. tropicalis, P. palmivora. P. citrophthora and P. meadii) representing hosts such as black pepper, cardamom, nutmeg, coconut, arecanut and cocoa were used to develop nucleic acid-based diagnostic tools viz., polymerase chain reaction (PCR), real-time PCR, loop-mediated isothermal amplification (LAMP) and real-time LAMP. Phytophthora genus-specific primers were designed from the conserved region of nuclear ribosomal DNA. Each of the assays was specific and detected different species of Phytophthora and not other pathogens (Rhizoctonia solani, Pythium vexans, Fusarium oxysporum and Colletotrichum gloeosporioides) and plant samples. Sensitivity assays indicated that, real-time PCR detected Phytophthora upto 1.3 fg, followed by LAMP (13 fg) and PCR (13 pg).

Published: February 2019

On farm trial on the effect of intercropping of summer moong (Vigna radiata) on growth, yield, and economics of turmeric (Curcuma longa L.) was conducted at farmer’s fields in adopted villages of Krishi Vigyan Kendra viz., Kandola Kalan, Kaimwala, Mehsampur and Fatehpur in Jalandhar district during 2012 and 2013. The experiment was laid out in randomized complete block design with nine treatments. The treatments were T1 - sole turmeric flat (30 cm x 20 cm), T2 - sole turmeric ridge (45 x 15 cm), T3 - sole turmeric ridge (60 x 10 cm), T4 - sole turmeric bed (67.5 cm), T5 - turmeric : summer moong (1:1) flat, T6 -turmeric : summer moong (1:1) ridge 45 x 20 cm, T7 - turmeric :summer moong (1:1) ridge 60 x 20 cm, T8 -turmeric : summer moong (2:1) bed 67.5 cm and T9 - turmeric : summer moong (2:2) bed 67.5 cm. In intercropping treatments, the planting of turmeric was done on the top of ridge and bed and summer moong was sown in furrows. The data on emergence count (30 and 60 DAS), plant height, tillers plant-1 (No.), dry matter accumulation, number of rhizomes (mother, primary, secondary), total rhizomes plant-1, rhizome yield (q ha-1) (fresh, dry and processed) were recorded. The treatments T8 and T9 where turmeric was planted on bed with summer moong in the furrow were found to be better for all the characters under study. The highest net returns of Rs 2.27 x 105 ha-1 with B : C ratio 4.89 was obtained in T9 -turmeric : summer moong (2:2) bed 67.5 cm followed by T8 -turmeric : summer moong (2:1) bed 67.5 cm and recorded lowest net returns of Rs 1.58 x 105 ha-1 with benefit: cost ratio 3.51 in T5 - turmeric : summer moong (1:1) flat. The study revealed that summer moong can be a better option as intercrop in turmeric than the sole turmeric crop for proper utilization of all resources.
Mycotoxigenic Aspergillus flavus from ginger and turmeric consumed in the Niger Delta Region of Nigeria
Authors: M I Godwin-Egein V C Okereke,
Published: February 2019

Ginger and turmeric sold in the open markets and retail outlets in southern Nigeria were sampled between April and August, 2017. This period coincided with the first bimodal peak of the rainy season of the 2017 cropping season. Malt extract agar (MEA) and Dichloran 18% glycerol (DG18) media were used to isolate fungi from samples with or without surface sterilisation. Aspergillus spp isolated were examined for the production of orange-yellow pigmentation and blue fluorescence on the reverse side of the plate on CAM under UV light. Aflatoxin production by Aspergillus flavus on yeast extract sucrose (YES) was verified quantitatively using High Performance Liquid Chromatography (HPLC). Data showed that Fusarium, Penicillium and Aspergillus spp were the dominant fungal flora. Toxigenic isolates of A. flavus; AFg1, AFg3, AFt1, and AFt3 produced both orange-yellow pigmentation and blue fluorescence on CAM. The production of AFB1 and AFB2 on YES medium was confirmed using HPLC. The occurrence of toxigenic fungi indicates that there is a potential risk of mycotoxin contamination in ginger and turmeric consumed in southern Nigeria and problems can arise from contamination with aflatoxins.

Terra Incognita of Russian Bibliology: On Application and Localization of the Concept of “Russian North”
Authors: Trifilova Elena S.
Published: February 2019

The concept of “Russian North” is actively used in the media and in scientific literature. However, only few people think about its meaning. In the field of bibliology, the uncertainty of the idea of the Russian North territory complicates the selection of material for studying the book culture of this region. Analysis of the practice of using the concept shows that this problem appeared in the 19th century, when researchers differently defined the territory of the Russian North. In most cases, they were directed by the conclusions of historical science, which included in this region all the lands ever and in any way connected with the Novgorod Republic. This stereotype, formed almost 200 years ago, still exists now. However, the data obtained as a result of archeological and historical research carried out over the last 50 years cast doubts on the validity of the Novgorod paradigm.

In ethnography, methods of which began to be actively used in book studies in the second half of the 20th century, there is also no unified opinion on the territorial structure of the Russian North. Attempts to combine its borders with the areas of distribution of North Russian dialects and the complex of traditional North Russian household culture have shown ineffectiveness of this method in modern world.

On the one hand, new culturological theories that appeared at the cusp of the 20th—21st centuries offered new aspects for studying the Russian North, but on the other hand, they moved it into the field of abstraction, actually depriving it of its geographic boundaries. As long as the issue of the Russian North localization remains open in bibliology, this study attempts to systemize and analyze the accumulated information. As a result, the article raises questions about the necessity of further preservation of the stereotype; about the eligibility to classify to the Russian North the territories that are not related to it in terms of geography, or have a conditional relation from the point of view of history; about the rightness of application of the toponymic form of the concept in relation to the North European part of Russia, without regard to the North of Siberia. In conclusion, the article makes some correction in relation to the authorship of the term “Russian North”, which is traditionally attributed to the Civil Governor of Arkhangelsk A.P. Engelgardt.

Published: February 2019

In nature chitosan is a plentiful polymer with high heavy metal ion uptake capacity due to chitosan’s functional groups that chelate with the positive surfaces of heavy metal ions. In this study, epichlorohydrin was used as a crosslink to prepare the copper-imprinted chitosan as a pattern to enable the selectivity property and increase adsorption capacity. The effects of the cross-linker, PH, initial concentration and time were examined in this study to identify the optimum amount of each to remove copper metal ions from waste water by imprinted chitosan. This composite was characterized by Fourier-transform infrared spectroscopy (FTIR) test to determine the existence of copper ions in chitosan crosslinked with epichlorohydrin. Scanning electron microscopy (SEM) tests were also done to compare the surfaces of crosslinked chitosan and the removal of copper by imprinted chitosan. PH adsorption was tested from 3 to 7 and the initial concentration and time investigated were between 10 and 100 mg/l and 0 and 120 minutes respectively. The maximum capacity to adsorb was found to be at PH 7, initial concentration of 100mg/l at 90 minutes with 0.1 gr chitosan. Ultimately, the maximum adsorbent amount achieved for effective Cu(II) removal was 74.37 mg/g.

Published: February 2019

The southern Sumatera region experiences one rainy season and one dry season in a year associated with seasonal change in monsoonal winds. The peak of rainy season is occurring in November-December-January during the northwest monsoon season, while the dry season comes in June-July-August during the southeast monsoon season. This study is designed to evaluate possible influence of the coupled ocean-atmospheric modes in the tropical Indo-Pacific region, namely the El Niño-Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD) on the rainfall variability over the catchment area of the Music Basin, South Sumatera. The ENSO and IOD occurrences were reflected by the variability of sea surface temperature (SST) in the tropical Pacific and Indian Ocean, respectively. During El Niño and/or positive IOD episode, negative SST anomalies cover the eastern tropical Indian Ocean and western tropical Pacific including the Indonesian seas, leading to suppress convective activities that result in reduce precipitation over the maritime continent. The situation is reversed during La Niña and/or negative IOD event. The results revealed that the high topography area (e.g. Bukit Barisan) was shown to be instrumental to the pattern of rainfall variability. During the 2010 negative IOD co-occurring with La Niña event, the rainfall was significantly increase over the region. This excess rainfall was associated with warm SST anomaly over the eastern tropical Indian Ocean and the Indonesian seas. On the other hand, extreme drought event tends to occur during the 2015 positive IOD simultaneously with the occurrence of the El Niño events Investigation on the SST patterns revealed that cold SST anomalies covered the Indonesian seas during the peak phase of the 2015 positive IOD and El Niño event.

Authors: Mardiyanto Mardiyanto , Fithri Najma Annuria , Tandry Martina
Published: February 2019

Mefenamic acid as pain relief drug belongs to the biopharmaceutics classification system (BCS) class II which is practically insoluble in water causing extremely low dissolution in gastrointestinal tract. The self nanoemulsifying drug delivery system (SNEDDS) is a new innovation pharmaceutical dosage form that has effectively known to increase solubilization of hydrophobic drug in polar solvent. In this study the capryol-90 was selected as oil phase in SNEDDS as it showed maximal solubility of mefenamic acid (20 mg/mL). Combination of polysorbate-80 and PEG-400 as a generally regarded as safe (GRAS) excipient were used as surfactant and co-surfactant in SNEDDS due to its high HLB property that can increase mefenamic acid solubility in water. The ternary phase diagram of capryol-90, polysorbate-80, and PEG-400 was constructed in advance to obtain the component concentration of spontaneous nanoemulsion region. Model simplex-lattice-design cooperated in Design-Expert®10 was used to define SNEDDS mefenamic acid formula. Optimized mefenamic acid SNEDDS formula consisted of 20% capryol-90, 31.62% polysorbate-80, and 48.38% PEG-400. Characterization study of Optimized mefenamic acid SNEDDS formula showed improvement of drug content (102.820 ± 4.950)%, emulsification time (421.015 ± 1.290) second, and viscosity (0.927 ± 0.017) mm2/s 30oC. One way ANOVA statistical analysis result of optimal formula SNEDDS (105.210 ± 4.425)% of drug content, commercial generic caplet (0.917 ± 0.094)%, and mefenamic acid powder capsule (10.446 ± 0,333)% gave significant value (sig*) below than 0.05. Optimal formula proved that SNEDDS can significantly increase mefenamic acid dissolution of pH 7.4 (ileum fluid). The optimal formula of mefenamic acid SNEDDS successfully formed an uniformity droplet size (PDI 0.18) with mean size 241.9 nm and  the surface charge has a value of -16.5 mV respectively.

The high cellulosic content of rice husk can be utilized as a feedstock for pulp and biofuel. Pretreatment is necessary to break the bonds in the complex lignocellulose matrices addressing the cellulose access. This work aims to utilize the rice husk using dilute acid and alkaline pretreatment experimentally and CFD modeling. The study consists of three series of research. The first stage was the dilute acid pretreatment with sulfuric acid concentration of 1% to 5% (v/v) at 85°C for 60 minutes, and alkaline pretreatment with NaOH concentration of 1% to 5% (w/v) at 85oC for 30 minutes separately. The second stage used the combination of both pretreatment. Moreover the last stage of research was hydrodynamic modeling of pretreatment process by CFD (ANSYS FLUENT 16). The experimental results showed that the lowest lignin content after acid pretreatment was about 10.74%. Alkaline pretreatment produced the lowest lignin content of 4.35%. The highest cellulose content was 66.75 % for acid-alkaline pretreatment. The lowest content of lignin was about 6.09% for acid-alkaline pretreatment. The lowest performance of alkaline pretreatment on HWS (hot water solubility) of about 7.34% can be enhanced to 9.71% by using a combination alkaline-acid. The combined pretreatments result hemicellulose of about 9.59% (alkaline-acid) and 9.27% (acid-alkaline). Modeling results showed that the mixing area had the minimum pressure of about -6250 Pa which is vortex leading minimum efficiency of mixing. The rice husk flowed upward to the upper level and mixed with reagent in the perfect mixing.

Background: Endovascular methods for hemorrhage control, including resuscitative endovascular balloon occlusion of the aorta (REBOA), are evolving and are increasingly being applied clinically. Partial flow strategies to mitigate the consequences of complete aortic occlusion have been demonstrated in pre-clinical models to enhance REBOA and expand its application to various shock states. Initial studies demonstrated that controlled partial flow requires precision beyond the capabilities of manual balloon volume adjustment, therefore automation is required. Our group previously developed a proof-of-concept computer-controlled extracorporeal flow circuit capable of precision aortic flow regulation, but it was not clinically applicable. To bring this concept closer to clinical applicability, we have developed the first endovascular strategy to achieve precision aortic flow regulation, termed endovascular variable aortic control (EVAC).
Methods: Following instrumentation, five Yorkshire-cross swine were subjected to controlled 25% hemorrhage, followed by precision low volume aortic flow regulation using a commercially available compliant balloon catheter pre-positioned in the descending thoracic aorta, connected to a custom, wireless syringe pump. Closed-loop feed-back algorithms based on streaming physiologic data were used to determine balloon volume changes.
Results: The EVAC syringe pump was highly eff ective at maintaining precise aortic fl ow throughout the 45-minute intervention period during steady-state conditions as well as during rapid fluid administration. Aortic flow and distal mean arterial pressure remained stable during EVAC, despite changing proximal hemodynamics. Balloon volume was dynamic, averaging over 500 changes during intervention, with a mean volume change of 6.7 μL and a maximal change of 100 μL. Conclusions: The EVAC syringe pump is capable of achieving aortic flow regulation with high precision, beyond what is achievable with manual control. This serves as a model for future device design, enabling as of yet unachievable clinical therapies for hemorrhage and shock states. Future technological development is required to fully translate this into clinical use.

Published: February 2019

Background: With the growing use of REBOA as an alternative to Emergency Department thoracotomy in select patients, the algorithms are still evolving, and current guidelines for resuscitative endovascular balloon occlusion of the aorta (REBOA) use appear to have gaps as evidenced by this case. Most algorithms include chest x-ray, focused assessment with sonography for trauma (FAST), and pelvic x-ray to guide where to place the device, either in zone 1 or zone 3. There is a lack of guidance for patients in whom all three of these studies are negative, which we define as a non-diagnostic triad (NDT). Furthermore, there is a lack of guidance after placement of the device in patients who fail to respond or only minimally respond.Methods: We describe a diffi cult case where a blunt trauma patient with unstable hemodynamics had marginal response to placement of zone 1 REBOA, while physical exam and imaging in the trauma bay did not reveal a source for his hypotension.Results: The patient was sent to the CT scanner whereupon multiple injuries were identifi ed and detailed in the case. The patient unfortunately expired soon after.Conclusions: Further clinical studies with better classification are needed in order to better understand the significance of REBOA responders and non-responders in patients with an unknown source of hypotension. The NDT of negative chest x-ray, FAST, and pelvic x-ray represent a significantly challenging patient population that should be studied further.
