Authors: Andreatta Cidimar , Allevato Norma Suely Gomes , Pinto Antonio Henrique
Published: May 2018

Este artigo traz uma versão ampliada da Comunicação Científica apresentada no XIII Encontro Paulista de Educação Matemática (EPEM), com recortes dos resultados finais de uma pesquisa que envolveu uma prática de ensino com abordagem etnomatemática com estudantes dos anos finais do ensino fundamental numa escola municipal comunitária rural do município de Colatina, estado do Espírito Santo. A organização didático-pedagógica do trabalho na referida escola está consolidada na Pedagogia da Alternância, proporcionando momentos de formação na escola e no contexto familiar. Neste estudo apresentamos as situações-problema desenvolvidas para dinamizar as atividades com os números inteiros, proporcionalidade e porcentagem, de forma que os estudantes puderam perceber – ou não – a importância e a relação das propostas em/com seus cotidianos. Puderam aprofundar os conceitos de números inteiros, utilizando-se de diferentes estratégias de resolução e reconheceram os diferentes tipos de “fazer matemática” a partir da cultura familiar e do contexto em que estão inseridos, ratificando uma das perspectivas da Educação do Campo: a valorização da cultura e do meio em que vivem os sujeitos, confirmando proximidade e familiaridade com a Etnomatemática.

Up to present, the dairy farmers only able to meet 25-30 percent of all milk demand in Indonesia, although milk and its derivatives continues to increase steadily. This condition occurs due to low milk productivity, small-scale dairy farm unit, inadequate government policies as well as economic globalization. The objectives of this study are, first, to measure the competitiveness of the small-scale dairy farm. Second, to evaluate the impact of government policies. Third, lastly, to analyse the implication of price changes on input-output. A Policy Analysis Matrix (PAM) for data is applied. The results show that, first, the small-scale dairy farms operate in competitiveness. Second, so far government policies did not provide adequate incentives and directly promote the dairy farms’ competitiveness. Third, high import tariff (15 percent) could significantly protect the competitiveness of the small-scale dairy farms.
Community Engagement in Social Work Education: Building Pedagogical Pathways
Authors: Bhagwan Raisuyah
Published: May 2018

Momentum is growing steadily around community engagement, both locally and abroad, as an equal partner to the initial two missions in higher education: teaching and research. As attention grows towards community engagement, academics will have to consider how to advance this mission within their teaching and research functions. It is within this context that it becomes crucial to provide clarity on the terms â€œengagementâ€ and â€œco-production of knowledgeâ€, more especially, how social work education can enable community engagement. This article provides a conceptual review of these terms and builds a rationale for engagement. It also reflects the natural synergy social work education has with engagement and highlights three important pedagogical pathways, namely community-based teaching, research, and outreach as a means to advancing engagement in social work education.
Birth Registration and Perceived Social Exclusion: Insights from Participants' Narratives
Authors: Chereni Admire
Published: May 2018

Birth registration is becoming an important arena of political mobilisation for human rights. Discourses about civil registration advanced in the civil society and academic circles tend to frame birth registration in citizenship terms, arguing that (a)Â a birth certificate is indispensable in realising the childâ€™s right to a name, nationality and citizenship, and (b)Â both the delay in registering and failure to register a childâ€™s birth compound the social exclusion of that child. However, narratives that connect birth registration and social exclusion in a causal relationship are seldom premised on empirical evidence. Drawing on qualitative key informant interviews, this article examines how non-birth registration relates to social exclusion of children. Participantsâ€™ narratives generated in Zimbabweâ€™s Bindura District revealed that non-birth registration is entangled with multiple dimensions of social exclusion, potentially giving rise to marginalisation of children in various spheres of society.

The Never-ending Story of Law and Electoral System in Lesotho
Authors: Nyane Hoolo
Published: May 2018

While electoral discontent has been the enduring feature of constitutional democracy in Lesotho since independence, disagreement over electoral system is a fairly recent phenomenon. When the country attained independence in 1966 from Britain, electoral system was not necessarily one of the topical issues of pre-independence constitutional negotiations. The major issues were the powers of the monarch, the office of prime minister, the command of the army and many more.Â  It was taken for granted that the country would use the British-based plurality electoral system.Â  This is the system which the country used until early 2000s when the electoral laws were reformed to anchor a new mixed electoral system.Â  When the new electoral laws were ultimately passed in 2001, the country transitioned from a plurality electoral system to a two-ballot mixed member proportional system. By this time, electoral system had acquired prominence in politico-legal discourse in Lesotho.Â  In the run-up to 2007 elections, bigger political parties orchestrated the manipulation of electoral laws which culminated in clearly distorted electoral outcomes. The manipulations motivated further reforms in the run-up to 2012 election which resulted in the single-ballot mixed member proportional system. The purpose of this paper is to critically evaluate how electoral laws have anchored electoral system reforms throughout the various historical epochs in Lesotho since independence. The paper contends that while the country has been courageous, unlike most of its peers, to introduce far-reaching electoral system changes, the reform of electoral laws has not been so helpful in attaining the higher objectives of political inclusivity, constitutionalism and stability in Lesotho.

Large-scale QM/MM free energy simulations of enzyme catalysis reveal the influence of charge transfer
Authors: Kulik Heather
Published: May 2018

Hybrid quantum mechanical-molecular mechanical (QM/MM) simulations provide key insights into enzyme structure–function relationships. Numerous studies have demonstrated that large QM regions are needed to systematically converge ground state, zero temperature properties with electrostatic embedding QM/MM. However, it is not well known if ab initio QM/MM free energy simulations have this same dependence, in part due to the hundreds of thousands of energy evaluations required for free energy estimations that in turn limit QM region size. Here, we leverage recent advances in electronic structure efficiency and accuracy to carry out range-separated hybrid density functional theory free energy simulations in a representative methyltransferase. By studying 200 ps of ab initio QM/MM dynamics for each of five QM regions from minimal (64 atoms) to one-sixth of the protein (544 atoms), we identify critical differences between large and small QM region QM/MM in charge transfer between substrates and active site residues as well as in geometric structure and dynamics that coincide with differences in predicted free energy barriers. Distinct geometric and electronic structure features in the largest QM region indicate that important aspects of enzymatic rate enhancement in methyltransferases are identified with large-scale electronic structure.

Published: May 2018

Carbon is the most widely used electrode for the supercapacitors. To predict the capacitance of carbon-based supercapacitors, this work applies three machine learning (ML) methods, including linear regression, Lasso and artificial neural network. For training the ML process, we extracted data from hundreds of published papers. Moreover, five variables were selected to figure out their impact on capacitance, including specific surface area, calculated pore size, ID/IG ratio, N-doping level and voltage window. By evaluated with the real data, all of three methods achieve acceptable prediction results, and ANN exhibits the best performance. More importantly, this work shows the potential of ML in material science and advanced applications.
Quantitative Image Analysis of Fractal-like Thin Films of Organic Semiconductors
Authors: Zhu Weikun , Mohammadi Erfan , Diao Ying
Published: May 2018

Morphology modulation offers significant control over organic electronic device performance. However, morphology quantification has been rarely carried out via image analysis. In this work, we designed a MATLAB program to evaluate two key parameters describing morphology of small molecule semiconductor thin films: fractal dimension and film coverage. We then employ this program in a case study of meniscus-guided coating of 2,7-dioctyl[1]benzothieno[3,2-b][1]benzothiophene (C8-BTBT) under various conditions to analyze a diverse and complex morphology set. The evolution of morphology in terms of fractal dimension and film coverage was studied as a function of coating speed. We discovered that combined fractal dimension and film coverage can quantitatively capture the key characteristics of C8-BTBT thin film morphology; change of these two parameters further inform morphology transition. Furthermore, fractal dimension could potentially shed light on thin film growth mechanisms.

Published: May 2018

O objetivo do trabalho foi avaliar a interação genótipo X ambiente para caracteres de cenoura, bem como estimar a correlação entre caracteres em sistemas agroecológicos de produção no Distrito Federal. Foram realizados ensaios em áreas de cultivo agroecológico (Agricultura Natural – AN e Agricultura Orgânica - AO) com a avaliação das seguintes características: incidência de queima-das-folhas, ocorrência de rachadura, comprimento de raiz, diâmetro da raiz, massa da raiz, diâmetro do xilema, razão entre o diâmetro do xilema e diâmetro da raiz, formato de ponta e do ombro da raiz e parâmetro a* do xilema e do floema. O delineamento experimental utilizado foi de blocos ao acaso com 100 famílias de meio-irmãos em duas repetições. Foram efetuadas análise de variância conjunta e para cada sistema e ainda estimativas de correlação. Pôde-se verificar que os caracteres diâmetro da raiz, massa, diâmetro de xilema e razão entre diâmetro de xilema e diâmetro da raiz não apresentaram interação famílias x sistemas agroecológico. Os parâmetros a* do xilema e a* do floema correlacioram-se significativamente nos dois sistemas de cultivo. Observou-se que quanto maior for o diametro do xilema, menor será a concentração de carotenóides totais no xilema da raíz. Também foi possível verificar que raízes com maior comprimento apresentam menor índice de rachadura. Sugere-se a instalação de ensaios em um único local visto que as características que apresentam estreita relação com produtividade de raízes (massa, diâmetro de raiz, diâmetro do xilema e razão diâmetro do xilema/diâmetro da raiz) evidenciaram comportamento estável dos genótipos nos diferentes sistemas.

Published: May 2018

Muá¸¥ammad SaÊ»Ä«d Al-â€˜AshmÄwÄ« and Muá¸¥ammad Shaá¸¥rÅ«r are well known as contemporary Muslim thinkers. This article tries to map their contemporary ideas on Islamic jurisprudence. The main data of this research taken mainly from the works both of Al-â€˜AshmÄwÄ« and Shaá¸¥rÅ«r. In particular, the paper tries to analyze Al-â€˜AshmÄwÄ«â€˜s ideas on sharia, politics, hijab, marriage and divorce. On the other hand, the ideas of Shahrour on al-Qur'an, Sunnah and Fiqh, the theory of borders, pluralism, the commandment, inheritance, hijab, marriage, divorce, dowry, politics, and imamate are also critizised. After analyzing their lives and their ideas on Islamic jurisprudence, the paper found that their social, educational and practical backgrounds have affected their intellectual formations and ideas. Ashmawi is encouraged by diligence and enlightenment and is believed to be enlightened. Shahrour, however, takes a new approach in order to create the á¸¥udÅ«d theory as a new way. As well as their intellectual background, Ashmawi has a good queen in Arabic, English and French as well as religion, Sharia, jurisprudence and theology. Shahrour is a good queen in Arabic, English, Russian, philosophy, philology and historical language.
Hassan Hanafiâ€™s Response to Western Hegemony in Muqaddimah FÄ« â€˜Ilmi al-IstighrÄb Through Hegemony Theory of Gramsci
Authors: Feriyadi Feriyadi , Hadi Syamsul
Published: May 2018

This is a literature study on Hassan Hanafi's response to the hegemony of Western civilization by using hegemony theory of Gramsci. One of the responses discussed in this research is the discussion of Occidentalism. Hanafi introduced the notion of Occidentalism as a study of the West from the eyes of the East. He acknowledges that the West is a major entrant and also a source of scientific knowledge in our consciousness. Therefore, the West occupies a very important position. Such an important position according to Hanafi received less serious response by Muslim intellectuals. Hanafi's Occidentalism was intended to confront Western civilization's hegemony of the East consciousness. With Occidentalism it is expected that the Eastern position which has been used as the object of the study may change, that is to be an observer or researcher. In addition, Hanafiâ€™s Occidentalism wants to end the Western myth as a representation and the holder of world civilization supremacy. Western studies of the East have so far led to a stereotype that the rise and fall of a civilization can be measured by the benchmarks of Western civilization. Such an attitude, eventually foster inferiority to other civilizations. The main source of this study is Hanafiâ€™s book entiteled Muqaddimah fÄ« â€˜Ilmi al-IstighrÄb. The paper found that Hanafiâ€™s Occidentalism is not as a counterpart of Orientalism, not as a tool in fighting against Western civilization, nor as anti-Western, but the Occidentalism used as a means to position the West as one of civilizations without narrow fanaticism, without blind thought, while enhancing local wisdom and Eastern tradition amid advances in technology and science.
The Substance of The Formal Prohibition of The Riba: Islamic Finance and The Tie with The Real Economy
Authors: Mustofa Latif
Published: May 2018

Islamic Financial Institutions come up with sharia-compliant products mimicking one of their conventional counterpart. This particular development is one of the unintended consequences under the interpretation of the prohibition of interest. Islamic Finance Institutions need to find substitute for profit-generating mechanism. There is no consequential difference between â€˜interestfreeâ€™ and interest-bearing products on the practical level. This paper attempts to deal with the question of the interpretation of riba on a theoretical level. This paper argues that equity-financing should be preferred to debt-financing. In doing so, this paper embraces a juristic approach to arrive at the intended conclusion. However, debt-financing could be utilised where deemed appropriate and no equity-financing method is applicable to a particular project.

A Tactile P300 Brain-Computer Interface: Principle and Paradigm
Authors: Belhaouari Aness , Belkacem Abdelkader Nasreddine , Berrached Nasreddine
Published: May 2018

The P300 based non-invasive brain-computer interfaces (BCIs) are the focus of several research communities in order to move a BCI from a laboratory demonstration to real-life applications. The development and implementation of a BCI system might be the only option left for severely disabled patients to be able to communicate with environment. Therefore, most of the BCI researches have been based on the visual stimulation using the electroencephalogram (EEG) for measuring the brain waves such as event-related potential (ERP). However, recent studies revealed that the tactile modality offers a gaze-independent alternative to the user for reducing eye strain and fatigue. In this context, we investigated a tactile brain-computer interface (tBCI) based on ERP responses to vibro-tactile stimuli around the face and fingers. With regard to novelty oddball paradigm and target-processing, the users have exhibited a different event-related potential in case of a target stimulus. The results of our experiments showed very clear shape of P300 component caused by tactile stimuli which is going to be used in real-time control applications. The efficiency of our ERP-based BCI is strongly related to mean amplitude of the P300 components over 14 EEG channels which was used as a feature in the phase of SVM classification.

Abstract

Potential coal reserves in Indonesia are very abundant, but which became theÂ key issue is the utilization in Indonesia is still not optimal. One alternative to useÂ the coal is by converting it into synthetic gas (syngas), containing primarilyÂ hydrogen (H2) and Carbon Monoxide (CO). To create synthetic gas from coalÂ there are 4 kinds of process technology known in the world, i.e. Fixed-bedÂ gasifier, Fluidized-bed gasifier, Entrained-bed gasifier and Molten bath gasifier.Â There are 3 types of chemical industry to take advantage of this synthetic gas asÂ an alternative of their raw materials i.e., methanol, formic acid and ammoniaÂ industry. Currently they use natural gas as raw material. The more widespreadÂ use of natural gas for a variety of needs can disrupt the natural gas supply forÂ these industries in the future. Therefore, this synthetic gas can be used as anÂ alternative of raw material supply for these three types of chemical industry in theÂ future.

Abstrak

Potensi cadangan batubara di Indonesia sangat melimpah, namun yang menjadiÂ isu utama adalah pemanfaatannya di Indonesia masih belum optimal. Salah satuÂ alternatif pemanfaatan batubara tersebut adalah dengan mengkonversi batubaraÂ tersebut menjadi gas sintetik (syngas) yang kandungan utamanya adalahÂ Hidrogen (H2) dan Karbon Monoksida (CO). Untuk membuat gas sintetik dariÂ batubara ini ada 4 macam teknologi proses yang telah dikenal di dunia yaituÂ Fixed-bed gasifier, Fluidized-bed gasifier, Entrained-bed gasifier dan Molten bathÂ gasifier. Ada 3 jenis industri kimia yang dapat memanfaatkan gas sintetik iniÂ sebagai alternatif bahan bakunya yaitu industri metanol, industri asam formiat danÂ industri amonia. Saat ini mereka menggunakan gas alam sebagai bahan bakunya.Â Semakin meluasnya penggunaan gas alam untuk berbagai macam kebutuhanÂ dapat menyebabkan pasokan gas alam untuk ketiga jenis industri ini terganggu diÂ kemudian hari. Oleh karena itu gas sintetik ini dapat dimanfaatkan sebagaiÂ alternatif pasokan bahan baku untuk ketiga jenis industri kimia tersebutÂ kedepannya.

ABSTRAK

Deformasi dan perlakuan panas selalu menyertai proses pembuatan selongsong peluru karena kedua proses tersebutlah yang mampu mengatur bahan baku menjadi bentuk dan dimensi yang diinginkan serta sesuai dengan karakteristik yang dikehendaki. Padaun Cu-Zn 70/30 adalah bahan baku yang digunakan untuk pembuatan selongsong peluru, namun mampu bentuk paduan ini akibat deformasi dan perlakuan panas belum banyak diketahui. Oleh karena itu pada penelitian ini bertujuan untuk mempelajari pengaruh deformasi yang dilakukan pada suhu hangat terhadap mampu bentuk dingin dengan metode thermomechanical controlled processed menggunakan teknologi canai hangat. Teknologi canai hangat dilakukan dengan metode double pass reversible sebanyak 25% x 2, 30% x 2, dan 35% x 2 pada suhu 500oC. Pengamatan mampu bentuk dilakukan dengan pengujian tarik hanya sampai perpanjangan 20% serta uji tarik sampai putus. Hasil dari penelitian menunjukkan bahwa sifat mampu bentuk terbaik diperoleh pada benda uji yang dideformasi canai hangat di temperatur 500oC dengan derajat deformasi aktual sebesar 38.7%. Apabila dilihat dari sifat mampu bentuknya maka benda uji yang dideformasi canai hangat pada kondisi parameter penelitian ini memiliki nilai elongasi sebesar 10 % dengan nilai koefisien pengerasan regang yang tinggi sebesar 0.00228, nilai anisotropi normal rata-rata sebesar 0.5452, dan nilai anisotropi planar yaitu Î”r<1 sebesar -0.42.

Progesterone is a well known natural contraceptive, a drug of BCS class II, which was used in early centuries to protect from the side effects of estrogens like abortion. For the preformulation studies, the solubility of progesterone in various oils, solvents, surfactants and co-surfactants was determined for further formulation development. The Progesterone has been evaluated for XRD, DSC, Partition coefficient, melting point and its solubility is also checked in different solvents. Physico-chemical characterization studies showed that progesterone has a melting point of 1270C. The solubility of drug progesterone was evaluated in methanol, and ethanol. The analytical method developed for the estimation of progesterone in methanol and ethanol showed maximum absorbance at λmax of 241 nm and 247 nm respectively at pH 7.4.Linearity studies indicated that estimation of progesterone between 1.00 μg /ml to 10.00 μg /ml was found to be linear with regression equation of y = 0.0575x + 0.0041; R² = 0.9985 with methanol and y = 0.0442x+0.0041; R² = 0.9968 with ethanol. On the basis of solubility studies two oils with highest solubility (Oleic acid and Myritol), two surfactants (Tween80 and Tween20) and three co-surfactants (Ethanol, Propanol and PEG400) were selected respectively for further formulation studies. The above analytical parameters indicated that the developed UV Spectrophotometric method for progesterone was simple, accurate, precise and reproducible.

Solid dispersions in water soluble carriers have attracted considerable interests as a mean of improving the dissolution rate and hence possibly bioavailability range of hydrophobic drugs. The poor solubility of ciprofloxacin leads to poor dissolution and hence variation in bioavailability. The purpose of present investigation was formulation and evaluation of controlled release floating capsule of ciprofloxacin with improved solubility and dissolution rate. In present study solid dispersion using various carriers like mannitol and lactose in different ratios were prepared by solvent evaporation method. The prepared solid dispersions were characterized for drug content, solubility and dissolution rate. The dissolution rate substantially improved for ciprofloxacin from its solid dispersions compared with pure drug. Dissolution rate increased with increase in carrier content. The dissolution rate was increased 3 folds with solid dispersions containing 1:4 of drug: lactose. The granules of ciprofloxacin solid dispersion containing 1:4 of drug: lactose ratio was prepared by wet granulation method using polymer such as ethyl cellulose and HPMC. The prepared granules were evaluated to preformulation studies such as angle of repose (18.41-24.22), bulk density, tapped density, compressibility index (11.31-12.75) and hausner’s ratio. All the parameters shows that the granules having good flow properties. These granules had converted into the capsule forms. Then the formulated capsules were taken to the evaluation studies such as weight variation, release study, buoyancy and floating duration (more than 6 hrs.). We can conclude that all the parameters were within the acceptable limits.

Naringi crenulata(Roxb.) Nicolson, is a rare medicinal plant belonging to the family Rutaceae. It is a spinous tree and has great medicinal value. During the present study a rapid, simple, accurate and specific HPTLC method for quantitative estimation of quercetin present in the dried leaf powder and callus of N. crenulata has been developed .The method used in this work resulted in good peak shape and enabled good resolution of quercetin from N. crenulata samples. Quercetin was identified in in vivo (leaf) and in vitro (six weeks old callus) tissues. Presence of isolated quercetin was further confirmed by superimposable IR spectra of isolated and authentic samples of quercetin and NMR spectra of isolated quercetin. Variation in quercetin content in in vivo and in vitro samples in N. crenulata was observed. In vivo leaf had maximum amount of quercetin (0.13%) while minimum amount was found in in vitro callus (0.032%). High content of quercetin in leaf shows its potential of synthesizing quercetin. This study is also of practical importance because flavonoid quercetin is the most active of all flavonoids. Many medicinal plants owe their activity to their high quercetin content. Several studies revealed quercetin’s significant anti-inflammatory activity due to direct inhibition of initial processes of inflammation. It also has potent antitumor and antioxidant properties including the inhibition of cancer cell proliferation and migration.This study is of practical importance because compound quercetin was firstly reported to be isolated from callus of N. Crenulata.
