Desempenho acadêmico discente e sua relação com a avaliação docente: proposta de framework teórico
Authors: Azevedo Lafetá Rabelo Anamaria , Paixão Roberto Brazileiro
Published: December 2018

Este estudo tem como objetivo retomar um debate teórico e obter um framework de análise sobre a possível influência das notas dos alunos na avaliação que eles fazem de seus professores. Buscou-se entender a relação nota-avaliação por meio do levantamento de estudos anteriores e da revisão bibliográfica sobre o assunto. Desenvolveu-se uma estrutura conceitual de framework tendo como base o nível de significância da relação entre desempenho acadêmico discente e avaliação docente. Os resultados da pesquisa apontaram que alguns autores reconhecem a relação na qual a nota do aluno interfere na avaliação do professor, explicada pelo pacto de leniência ou pela real aprendizagem. Por outro lado, alguns autores mostram que essa relação pode ser não significativa e que existem outras variáveis como gênero, idade e experiência do professor que também interferem na avaliação. Os resultados encontrados permitem uma melhor compreensão da relação na perspectiva de diversos autores, mas vale ressaltar a necessidade do uso de abordagens metodológicas distintas para estabelecer como a relação nota-avaliação acontece.

Authors: Yen Tran Thi Hai , Nho Dan Le , Duc Le Hoang , Tung Bui Thanh , Hue Pham Thi Minh
Published: December 2018

Background: Amphotericin B (AmB) is a drug of choice in the therapy of systemic fungal infection because of its board-spectrum antifungal activity. However, its conventional formulation has many side effects such as acute and chronic nephrotoxicity. Liposomes have been developed to reduce the drug’s toxicity. However, they had to meet strict stability criteria. In general, liposomes can be freeze-dried to inhibit liposomes infusion, phospholipids degradation during storage. Liposomal size usually increases after freeze-drying because of being influenced by many factors in freezing, lyophilizing and rehydration processes. Therefore, cryoprotectants are used to stabilize liposomal vesicles during freeze-drying process.  Objective: In the present study, we developed AmB liposomal suspension and lyophilized liposomes loaded with AmB, evaluated the effect of different cryoprotectants on the characterization of freeze-dried AmB liposomes.  Methods: In this study, AmB liposomes were prepared from hydrogenated soy phosphatidylcholine, distearoylphosphatidylglycerol and cholesterol by thin lipid film hydration method using different hydrate mediums likely: Glucose solution, citrate buffer, phosphate buffer. High-pressure homogenization and extrusion methods were used to reducing vesicles size. Dynamic light scattering was used to characterize liposomal size, and size distribution. HPLC method was used to assay drug and determine entrapment efficiency. Liposomal suspension was lyophilized with different cryoprotectants: Sucrose, mannitol, lactose, trehalose and glycerol. Differential scanning calorimetry was used to study lyophilized cake.  Results: We found that liposomal suspension with hydration medium10 mM citrate buffer pH 5.5 had a small average size (<100nm) and narrow distribution (PDI <0.2). Sucrose and trehalose stabilized vesicles size during freezing process, and lyophilized liposomes with sucrose and trehalose had an elegant appearance, yellow, compact cake. DSC study showed that sucrose and trehalose in lyophilized cake were amorphous. The cake was rehydrated within 10 seconds to form liposomal suspension, in which vesicles size was less than 140 nm.  Conclusion: We have developed successfully AmB liposomal suspension and lyophilized liposomes loaded with AmB. Sucrose and trehalose can be used as cryoprotectants in the freeze-drying and reconstitution process.

Authors: Jehangir Irum , Ahmad Syed Farhan , Jehangir Maryam , Jamal Anwar , Khan Momin
Published: December 2018

Background:

Leishmaniasis is the major cause of mortality in under-developed countries.
One of the main problems in leishmaniasis is the limited number of drug options, resistance
and side effects. Such a situation requires to study the new chemical series with anti-leishmanial
activity.

Objective:

To assess the anti-leishmanial activity of antibacterial and antifungal drugs.

Methods:

We have applied an integrative approach based on computational and in vitro methods
to elucidate the efficacy of different antibacterial and antifungal drugs against Leishmania tropica
(KWH23). Firstly these compounds were analyzed using in silico molecular docking. This analysis
showed that the nystatin and azithromycin interacted with the active site amino acids of the target
protein leishmanolysin. The nystatin, followed by azithromycin, produced the lowest binding energies
indicating their inhibitive activity against the target. The efficacy of the docked drugs was
further validated in vitro which showed that our bioinformatics based predictions completely
agreed with experimental results. Stock solutions of drugs, media preparation and parasites cultures
were performed according to the standard in-vitro protocol.

Results:

We found that the half maximal inhibitory concentration (IC50) value of dosage form of
nystatin (10,000,00 U) and pure nystatin was 0.05701 µM and 0.00324 µM respectively. The IC50
value of combined azithromycin and nystatin (dosage and pure form) was 0.156 µg/ml and 0.0023
µg /ml (0.00248 µM) respectively. It was observed that IC50 value of nystatin is better than
azithromycin and pure form of drugs had significant activity than the dosage form of drugs.

Conclusion:

From these results, it was also proven that pure drugs combination result is much better
than all tested drugs results. The results of both in vitro and in silico studies clearly indicated
that comparatively, nystatin is the potential candidate drug in combat against Leishmania tropica.

Authors: Zhang Ting-He , Zhang Shao-Wu
Published: December 2018

Background:

Revealing the subcellular location of a newly discovered protein can bring insight into their function and guide research at the cellular level. The experimental methods currently used to identify the protein subcellular locations are both time-consuming and expensive. Thus, it is highly desired to develop computational methods for efficiently and effectively identifying the protein subcellular locations. Especially, the rapidly increasing number of protein sequences entering the genome databases has called for the development of automated analysis methods.

Methods:

In this review, we will describe the recent advances in predicting the protein subcellular locations with machine learning from the following aspects: i) Protein subcellular location benchmark dataset construction, ii) Protein feature representation and feature descriptors, iii) Common machine learning algorithms, iv) Cross-validation test methods and assessment metrics, v) Web servers.

Result & Conclusion:

Concomitant with a large number of protein sequences generated by highthroughput technologies, four future directions for predicting protein subcellular locations with machine learning should be paid attention. One direction is the selection of novel and effective features (e.g., statistics, physical-chemical, evolutional) from the sequences and structures of proteins. Another is the feature fusion strategy. The third is the design of a powerful predictor and the fourth one is the protein multiple location sites prediction.

Published: December 2018

Background:

The aerial parts of Dipsacus laciniatus are traditionally used in the
treatment of colds as cold tea; decoction prepared from its roots and aerial parts are used for the
treatment of diabetes and cancer, respectively. The extraction procedures and solvents are important
steps in the processing of bioactive constituents from the plant materials.

Objective:

The aim of this study was to evaluate in vitro antioxidant, antimicrobial, anticholinesterase
and cytotoxic activities for the first time in plant’s different extracts.

Methods:

The antioxidant activities of extracts were examined using FRAP and CUPRAC methods,
including total phenolic and flavonoids contents. In addition, the antimicrobial, anticholinesterase
and cytotoxic activities of extracts were investigated using microdilution, Ellman and MTT methods,
respectively.

Results:

In the present study, methanol extract showed stronger iron (III) ion reduction (FRAP) and
copper (II) ion reducing antioxidant capacity (CUPRAC) than other extracts and also contained
higher total phenolic and flavonoid compounds. It was also found that there was a linear relationship
between antioxidant activity and phenolic compounds in this study. It was demonstrated that the
chloroform and methanol extracts showed moderate antimicrobial activity against S. epidermidis and
C. albicans strains. The chloroform extract had a strong and selective cytotoxic activity for the
MCF-7 and HT-29 cell lines, while the methanol extract showed low cytotoxic activity on the same
cell lines. In addition, according to the obtained data, chloroform extract showed a toxic effect on
normal cell line (NIH/3T3), but other extracts showed no toxic effect.

Conclusion:

Since methanol extract has no toxic effect on normal cell line and has strong
antioxidant, anticholinesterase and antimicrobial activity, it is thought that this extract may be useful
as an antioxidant, anticholinesterase and antimicrobial agents in the future.

Authors: Alvarado Silva Carlos Alexis , Gamarra Victor
Published: December 2018

O controle de pressão durante a perfuração de poços de petróleo pode ser um dos processos mais complexos e perigosos do estágio da exploração. Este estudo propõe o desenho e a validação do desempenho dos Controladores de Modelo Interno (IMC e SIMC) para controlar a pressão na perfuração de poços de petróleo com base na técnica Manage Pressure Drilling (MPD). O MPD adiciona uma válvula de controle no sistema de perfuração para obter uma outra variável de manipulação na pressão no fundo do poço. Na primeira parte deste trabalho, obteve-se um modelo matemático linear do processo, fundamentado na mecânica dos fluidos. O processo dinâmico apresentou um elemento integrador, além disso, é considerado o acréscimo de um intervalo de tempo entre a ação da válvula e a resposta da variação da pressão no fundo do poço. Na segunda parte, o controlador IMC melhorado foi projetado para compensar o efeito do termo integrado com o atraso de tempo, procurando o melhor desempenho e robustez do sistema. Finalmente, o controlador proposto é testado por problemas comuns durante simulações de perfuração (perda de fluido, influxos, conexão de tubulação e perda de potência da bomba) mostrando sua viabilidade. Além disso, o desempenho do sistema de malha fechada é comparado com um controlador PI clássico.

Authors: Kachayeva G. I. , Mustafayev A. G.
Published: December 2018

ObjectivesThe aim of the work is to use neural networks to detect characteristic ECG signals that determine heart rhythm abnormalities and detect the corresponding heart disease. One of the most important factors for the timely provision of medical care is the rapid and accurate obtaining of information about the patient's state of health. The timeliness of diagnosis is often the main factor determining the patient's prognosis. While the accuracy of cardiological diagnosis has significantly increased in recent years due to the wide application of both instrumental and laboratory research methods, the percentage of diagnostic errors in cardiology remains high. Electrocardiography (ECG) consists ina non-invasive process of interpreting the electrical activity of the heart, allowing the speed and regularity of the heartbeat to be assessed. These data are then used to determine any heart defects or pathologies. However, automatic ECG analysis remains a challenging theoretical and practical task.

MethodsA MATLAB 8.6 (R2015b) Neural Network Toolbox was used to simulate artificial neural networksduring the design. A backpropagation algorithm was used for trainingthe neural network. The efficiency of the developed neural network model for ECG analysis was investigated using the MIT-BIH arrhythmia database.

ResultsThe accuracy of detection and extraction of the components of the ECG signal shows that the developed neural network model can be successfully used to detect heart diseases among patients. The sensitivity of the model was 71%, with a specificity of 89%. The elaboration of existing and development of new methods for processing electrocardiographic data allow the problem of timely diagnosis and prevention of cardiovascular diseases to be solvedat early stages of their detection.

ConclusionThe accuracy of detection and extraction of the ECG signal components shows that the developed neural network model can be used to detect heart diseases among patients.

Authors: Kuznetsov I. E. , Melnikov A. V. , Rogozin E. A. , Strashko O. V.
Published: December 2018

ObjectivesThe aim of the study is to increase the effectiveness of unmanned aerial vehicles (UAVs) in the context of destabilising meteorological factors on the basis of an identification of links and patterns of unmanned aerial vehicles operating in difficult weather conditions.

MethodsIn this work, in order to account for the effect of meteorological factors on the effectiveness of unmanned aerial vehicles, the methods of system analysis, mathematical modelling of atmospheric phenomena and processes, as well as probability theory and statistical assessment, were applied.

ResultAn analysis of open literature sources devoted to the issues of operation and practical application of unmanned aerial vehicles (UAVs) under the influence of environmental factors was carried out. A classification of destabilising influences (DI) affecting the performance of a UAV flight mission is developed and presented. The dynamic probabilistic indicator, which, in characterising the dynamics of UAV functions as a complex technical system is referred to as “time efficiency of the UAV flight mission”, is substantiated. A methodology for estimating the dynamic efficiency indicator of the UAV’s functionality during the performance of a flight mission (FM) underDI conditions is developed on the basisof a probabilistic model of the conflicting interaction between UAV and DI. Strategies for selecting the trajectories of flights around local zones in which UAVs can be influenced by DI are given. To estimate the DI intensity and determine the size of the local disturbance zone, a mathematical model is proposed, whose application makes it possible to improve the UAV functioning under complex meteorological conditions (CMC) by taking into account the information on the space-time variability of dangerous for UAV weather-related phenomena (DWP). In the process of constructing the UAV functioning model, the use of conflict theory methods permitted adequate models for the analysis and evaluation of the dynamic efficiency indicator of the UAV functioning during the performance of FM in DI conditions to be developed, as well as the patterns of meteorological factors influencing the effectiveness of the UAV application to be revealed.

ConclusionThe methodology proposed in the article makes it possible to increase the effectiveness of unmanned aerial vehicles (UAVs) under complex meteorological conditions by a time index of 20-30% as compared with traditional approaches.
INFOCOMMUNICATION SUPPORT OF THE ACTORS’ COLLABORATION IN THE INTERSUBJECTIVE MANAGEMENT THEORY
Authors: Moiseeva T. V. , Polyaeva N. Yu.
Published: December 2018

Objectives. The theory of intersubjective management, designed to manage social processes in society, is aimed at achieving mutual understanding and consensus among heterogeneous actors united in self-organized communities. Actors who are aware of themselves in a problem situation (rather than just viewing it from the outside) are motivated to solve it, and joint decisions are made by the entire community of actors who are forced to negotiate with each other, realizing that their own resources are not enough to solve the problem. The use of modern information and communication technologies could allow to increase the effectiveness of the decision-making process and reduce its time, providing actors with the means of interacting each other in the process of seeking likeminded people, negotiating and reaching consensus. Therefore, the aim of the research is to find means of infocommunication support for the theory of intersubjective management which help to organize the interaction of actors who found themselves in difficult problem situations in everyday life.

Method. The system approach, method of the comparative analysis are applied. For the purpose of better presentation the semantic mean of graphical visualization Free Mind is used.

Result. The analysis of modern infocommunication facilities, the most popular among potential actors, is carried out and their comparison is made. The evaluation of the capabilities of all the analyzed means from the point of view of their suitability to the needs of intersubjective management is given. The choice of the most suitable infocommunication facility for use in the company "TBM-Povolzhje" is made.

Conclusion. The analysis of infocommunication means allowed to present their wide spectrum for application in practice while using the theory of intersubjective management. The research was performed as part of the state budget theme "Intersubjective Management of Socio-technical Objects Innovative Development with the Use of Situations Ontological Models" (No. AAAA-A16-116040410061-0) of ICCS RAS.

Published: December 2018

ObjectivesThe aim of the study is to increase the energy efficiency of an arc furnace’s power supply system and low-voltage circuit. According to the aim of the research, the relevant tasks of determining the capacitor capacity for reactive power compensation and selecting a rational location for its installation are posed.

MethodsWithin the framework of the previously developed concept of changing the parameters of the switching transformer in the series compensation circuit, issues of efficient use and consumption of electrical energy by a high power linear load under sinusoidal mode are considered. The installation of static compensators using a direct compensation method with automatic control including 12 stages of regulation is proposed as a means of increasing the efficiency of the arc furnace. Challenges involved in increasing the efficiency of electric power supply to alternating current arc furnaces using compensating reactive power in a low-voltage circuit are considered.

ResultsThe viability of using the series compensation circuit of reactive power with the switching of capacitors in the winding of the higher voltage of the series switching transformer is demonstrated.

ConclusionIt is shown that for efficient use and consumption of electric energy by highpower linear load under sinusoidal conditions, it is advisable to apply the series compensation of reactive power with the switching of capacitors in the winding of the higher voltage of the series switching transformer. This makes it possible to increase the efficiency coefficient of electric arc furnace power supply devices by reducing the power losses in the power supply system and in the furnace lowvoltage circuit by 1.6 times, as well as reducing the total load in the power transformer by 1.36 times.

Published: December 2018

ObjectivesThe aim of the study is to consider the design of a device for the cautery of bleeding by the method of local freezing of the blood flow zone performed using a salt with a low cryohydrate dissolution temperature, as well as to model heat exchange processes when using this technique.

MethodA design for a device for cauterising bleeding using salts having a low dissolution temperature was developed. This ensures a high cooling intensity, shortening the time of formation of a thrombus stopping the blood flow. A model of the device was constructedaccording to the principlesgoverning the solidification of a viscous liquid and heat transfer associated with the dissolution of salts in water. The model was calculated using the finite difference method. A determination of haemostasis duration wasprovided by a numerical experiment.

ResultsPlots of the temperature dependence of the salt solution in water over time are obtained, reflecting the duration of the device's output to operating mode, as well as plots of duration of a 3 mm thick formation of solid phase blood against the temperature of the solution for different values of blood flow pressure in the wound area.

ConclusionOn the basis of the numerical experiment, it was established that ammonium nitrate can be used as a working substance (salt) in the device. When it is dissolved in water, the minimum temperature of the solution is 256 K. The selection of the salt type and its quantity should be guided by medical norms and regulations in order to avoid the process of frostbite of the tissues adjacent to the bleeding zone. It was shown that the duration of blood solidification and the formation of a thrombus of the required thickness depend significantly on the pressure of the blood flow in the wound area, which must be taken into account when designing the device.
EVALUATION OF ERRORS CAUSED BY FALURE OF ANTENNA SYSTEM ELEMENTS INAN AERODROME AUTOMATIC RADIO DIRECTION FINDER

Published: December 2018

ObjectivesThe aim of the study is to develop a mathematical model for determining the direction-finding error of an aerodrome automatic direction finder (ADF), depending on the position of the defective vibrator relative to the source of radio emission.

MethodsTo determine the direction-finding error depending on the mutual location of the defective ADF vibrator and direction finding towards the radio source, the method of Fourier series expansion of step-by-step sampling of the signal phases is used. The direction-finding error is defined as the difference in the sum of the first harmonics of the phase sample’s stepped envelope Fourier expansion of the fault-free and defective antenna systems.

ResultsIn this work, a mathematical model is obtained for determining the direction-finding error of the aerodrome automatic direction finder (ADF), depending on the mutual position of the defective vibrator and direction finding towards the radio source. The graph of the alteration of the ADF direction finding error is obtained depending on the position of the defective vibrator and the direction finding towards the source of radio emission. It is shown that during ADF operating in the quasi-Doppler mode, the failure of the vibrators located along the direction finding towards the source of radio emission does not lead to an error in direction finding. Conversely, during ADF operating in the differential-phase mode, the failure of the vibrators located along the direction finding towards the source of radio emission leads to a maximum direction-finding error, reaching 3.75є.

ConclusionWhen an aerodrome automatic direction finder (ADF) operates in a quasi-Doppler mode, the failure of the vibrators located along the direction finding towards the source of radio emission does not lead to an error in direction finding and, conversely, when the ADF operates in differential phase mode, this results in a maximum direction-finding error of 3.75є.

Esta pesquisa teve como objetivo avaliar a qualidade de painéis aglomerados produzidos com seis espécies de madeiras tropicais da Amazônia: Byrsonima crispa, Eschweilera coriacea, Eschweilera odora, Manilkara amazonica, Pouteria guianensis e Swartzia recurva. Foram produzidos painéis experimentais com densidade nominal de 0,75 g/cm3, utilizando a resina uréia-formaldeído na proporção de 8% de sólidos - base peso seco das partículas. Os painéis foram prensados com pressão específica de 4,0 MPa, temperatura de 160 ºC e tempo de prensagem de oito minutos. Os painéis foram avaliados com base nas seguintes propriedades: razão de compactação, absorção de água e inchamento em espessura 2 horas e 24 horas, módulos de elasticidade e de ruptura, tração perpendicular, resistência ao arrancamento de parafusos na superfície e topo. A baixa razão de compactação dos painéis produzidos comas espécies tropicais não afetou de forma significativa os resultados de suas propriedades físicas e mecânicas. Avaliações comparativas dos resultados obtidos com os requisitos da norma EN 312 (2003) e espécie referencial - Pinus taeda, demonstraram que as espécies Byrsonima crispa, Eschweilera coriacea, Eschweilera odora e Pouteria guianensis apresentam grande potencial para produção de painéis aglomerados.

Montaj hattı dengeleme probleminde işler,
öncelik ilişkilerine uygun olarak gecikmeleri olabildiği ölçüde dengeleyecek
şekilde istasyonlara atanır. Ergonomik anlamda iyi tasarlanmamış montaj
hatları, yalnızca verimlilik kayıplarına sebep olmakla kalmaz, işçilerde kas
iskelet sistemi hastalıklarına da yol açabilir.
Böyle olumsuzlukları önlemek için
montaj hattını dengelerken her bir istasyonun risk seviyesinin kabul edilebilir
seviyeye çekilmesi veya zorluk düzeyinin işçiler arasında dengeli olması da
amaçlanmalıdır. Bu çalışmada,
montaj hattı dengelemede, öncelik ilişkileri ile çevrim süresi kısıtına
ilaveten, regonomik risk düzeyini de dikkate alarak istasonları oluşturan yeni
bir model geliştirilmesi ele alınmıştır. Ayrıca, önerilen modelin klasik montaj
hattı dengeleem ile karşılaştırılması amacıyla, süre ve ergonomik risk
düzeyinin bileşkesinden oluşan performans ölçütü tanımlanmıştır. Geliştirilen
model, fırın üreten işletmenin  montaj
hattı için uygulanmıştır. Her iki montaj hattında işlem süreleri ölçülmüş,
öncelik ilişkileri çıkarılmış ve REBA yöntemi ile ergonomik risk düzeyleri
hesaplanmıştır. COMSOAL yöntemi kullanılarak yapılan hat dengelemede,  performans düzeyleri, %28,56 olurken,
geliştirilen model için %25,22 elde edilmiştir. Geliştirilen modelin %3,34 iyileştirme
sağladığı tesbit edilmiştir.

Rendahnya kesadaran masyarakat dalam membuang sampah pada tempatnya dan bahayanyamembuang sampah di sungai merupakan masalah yang paling serius di kalangan masyarakatDesa Pamagersari. Pemukiman masyarakat yang semakin padat dapat mengurangi lahan untukpenanaman pohon, sehingga hal tersebut dapat mengurangi resapan air hujan, sumur yang kering,timbulnya banjir bandang serta menyebabkan pemukiman warga menjadi kering dan gersang.Oleh karena itu kami memiliki program kerja yaitu pengadaan tong sampah dan budidaya tanamansengon dengan tujuan meningkatkan kesadaran masyarakat terkait masih banyaknyamasyarakat yang membuang sampah disungai. Untuk merealisasikan tujuan programkerja kami, kami memberikan tempat pembuangan sampah disekitar desa yang berfungsijuga sebagai sarana penghijauan lingkungan agar lingkungan tidak kering, tidak gersang dan tetapmemiliki resapan air. Air yang meresap ke dalam tanah dapat menambah debit air yang masuk kedalam sumber bertambah terutama untuk daerah yang tanahnya tidak mendukung sebagai tempatpembuatan sumur. Selain untuk peresapan air, hasil dari penanaman pohon tersebut juga dapatdimanfaat masyarakat sebagai sumber perekonomian.

Program Yuk Nabung Saham ini menjadi senjata ampuh bagi BEI dan pihak terkait dalam mengajak masyarakat dalam berinvestasi saham. Selama ini program ini hanya menyentuh masyarakat umum, kampus, dan sekolah negeri, swasta, namun masih di anggap haram bagi santri di pondok pesantren Darurrahmah sebagai mitra (1). Bentuk kendala selama ini kurangnya informasi yang jelas tentang pasar modal di Indonesia, padahal jika di kaji secara utuh berinvestasi di pasar modal khususnya di syariah mengikuti prosedur yang di Fatwakan oleh MUI nomor 80 yang mengatur penerapan prinsip syariah dalam mekanisme perdagangan efek bersifat ekuitas di pasar regular bursa efek. Isinya menjelaskan, transaksi saham dianggap sesuai syariah jika hanya melakukan jual-beli saham syariah, serta tidak melakukan transaksi yang dilarang secara syariah. Fatwa tersebut juga menegaskan, saham yang sudah dibeli boleh ditransaksikan kembali meskipun settlement baru dilaksanakan pada T+3 sesuai prinsip QabdhHukmi. Transaksi saham syariah di Bursa Efek Indonesia menggunakan akad Bai’ Al Musawamah.

Folha de S. Paulo e os 50 anos do Golpe de 1964: guerras de memórias no especial multimídia
Authors: Martins Allysson Viana
Published: December 2018

As guerras de memórias nas produções jornalísticas buscam sua constituição na história. Em épocas de convergência e digitalização, a memória e o jornalismo possuem novas configurações. Neste texto, averiguam-se as produções da Folha de S. Paulo sobre os 50 anos do golpe de 1964, através de descrições interpretativas. Hoje o veículo jornalístico mais acessado do país, a Folha já possuía relevância desde antes do golpe. De modo geral, observa-se que a estrutura jornalística padrão e as memórias pessoais são preteridas em detrimento de um modelo de informação mais didática e de uma utilização de documentos históricos, com as fontes individuais aparecendo para explicitar opiniões contrárias à narrativa oficial sustentada nas produções do veículo, sobretudo nas justificativas dos militares.

Cangkang sawit Sawit (Elaeis guineensis Jacg) dahulu dianggap sebagai limbah yang tidak bermanfaat dan hanya dipakai sebagai pengeras jalan serta campuran makanan ternak. Sekarang dengan kemajuan teknologi, beberapa hasil sampingan kelapa sawit seperti sabut dan cangkang sawit dapat diolah menjadi produk yang memiliki nilai ekonomi tinggi seperti arang aktif yang dapat digunakan pada pengobatan diare karena bersifat sebagai adsorben. Metode yang digunakan untuk membuat tablet arang aktif adalah metode granulasi basah dengan 2 macam formula. Uji sifat fisik tablet yang dilakukan antara lain keseragaman bobot dan ukuran, kekerasan, kerapuhan, serta waktu hancur tablet. Dari hasil penelitian diperoleh bahwa formula yang memberikan sifat fisik tablet paling baik adalah formula 2 dengan menggunakan dosis 125 mg arang aktif.
