أبو الأ على المودودي من
العلماء الذين يسمع دوّي صوتهم على مستوى العالم، و تقرأ كتبهم على أوسع نطاقه،
خصوصا تفسيره تفهيم القرآن، فإنّه قلّما تخلو منه متكبة علمية في الجامعات او
المدارس الإ سلا مية. وكان الهدف الأساسي من هذا التّفسير – كما أفاد بنفسه- هو
تزويد العوّام من النّاس بالفهم الصّحيح للقرآن الكريم، و تطليعهم علىمتطلبات
القرآن منهم في جميع مجالات حياتهم فردا و
مجتمعا، دون إشغالهم في المباحث الفلسفيّة و الآراء التفسيرية؛ و المؤلّف يُرى -
إلى حدّ كبير- موفّقاَ في تحقيق ما أراد،
حيث يشهد على ذلك إقبال عدد هائل من النّاس على قراء ته من ناحية، حيث
تم نقل كتبه إلى أكثر من ست عشرة لغة، و
أخرى، اختياره كمقرّر دراسيّ في المعاهد التّعليميّة على المستويات المختلفة، إلّا
أن المودودي قد خاض في بعض المعارك
والمغامرات العلميةالّتي أصبحت محل النّقاش بين
العلماء البارزين عربا وعجما،
وأثارت جدلا في الأوساط العلميّة؛وهذه الأوراق تتوخّى دراسة محايدة لمنهج المودوديفي

بالمأثور، وتوضيح كيفية العلاقة بينهما من حيث جوانب الاشتراك ـ كالتعامل مع
الروايات، وكون كل منهما مصدراً للآخر ــ ومن حيث جوانب الاختلاف بينهما كطريقة
عرض الروايات، ومجالات الموضوع، وقد توصلت إلى عدة نتائج من أبرزها عمق العلاقة
بين السيرة النبوية وبين التفسير بالمأثور، واعتماد كل منهما على الآخر.
آراء المفسرين في معنى الفاحشة الواردة في آيتي الحبس والايذاء (دراسة نقدية مقارنة)
Authors: Al-zyout Abdullah Ahmad , Al-zyout Abdulmevla 
Published: May 2019

تتناول هذه الدراسة آراء
المفسرين في معنى الفاحشة الواردة في آيتي الحبس والايذاء ــ وهما الآيتان الخامسة
عشرة والسادسة عشرة من سورة النساء ــ بهدف
الوصول إلى القول الراجح، المؤيد بالبراهين الواضحة، والمشفوع بمناقشة أدلة الفريق
الآخر.

وقد عمدت هذه الدراسة إلى
استقراء الأقوال التفسيرية القديمة والحديثة، فعرضتها ودرست أدلتها دراسة متأنية،
ثم بينت القول الرأي الراجح بالأدلة الواضحة، ودَفَعت الاعتراضات الواردة على هذا الرأي
الراجح.

وقد
خلصت هذه الدراسة إلى عدة نتائج، من
أبرزها: أن الراجح في معنى الفاحشة في هذا
السياق هو الزنا، وأن الثابت عن مجاهد ـ رحمه الله ـ في تفسيره للاسم الموصول (
اللذان) الرجلان الزانيان ، وليس إتيان الرَّجلُ الرَّجلَ، وأن عقوبة الحبس غير
معمول بها؛ لأنها كانت ممدودة إلى غاية، وأما عقوبة الأذى فلا تتعارض مع إقامة
الحدِّ على الزانيين، وأن السبيل كان مُجملاً وقد بينه الحديث النبوي الصحيح
Pour l’écologie, pour la démocratie
Authors: Chollet Antoine 
Published: May 2019

Antoine Chollet, qui dans notre revue avait déjà discuté le lien écologie-démocratie chez Cornelius Castoriadis 1 , dont il est un spécialiste, et qui dans ses ouvrages s’est illustré par sa défense de la démocratie directe en Suisse, où il enseigne, revient sur une thématique dont l’importance axiologique et stratégique pour les écologistes n’a pas toujours été suffisamment perçue. Il montre que les réflexes anti-écologistes du peuple sont un mythe et qu’il n’est pas déraisonnable de lui faire confiance dans la mesure où la pratique démocratique suppose « une connaissance de cause » en vue du bien commun. Ancrées dans une pragmatique du présent, la démocratie et ses institutions sont aussi l’outil par lequel le niveau local peut être dépassé pour affronter la crise écologique à son niveau planétaire.
Déclaration finale du « 1 er Sommet des sept peuples parmi les plus pauvres » (1989)
Authors: TOES 89  
Published: May 2019

En marge du G7 qui se tint à Paris en 1989, le contre-sommet organisé par la mouvance alternative TOES (The other economic summit) adopta le 15 juillet 1989, en coïncidence avec les célébrations du bicentenaire de la Révolution française, une déclaration finale adressée au Secrétaire général des Nations unies. Survenant dans le contexte de la politique des « réformes structurelles » imposée au Sud par le Fond monétaire international, cette déclaratoin affirmait qu’« une révision radicale du modèle de développement que le Nord impose au Sud est indispensable, et cela dans l’intérêt du Nord et pas seulement du Sud ». Elle ne réclamait pas seulement l’annulation de la dette des pays du Sud, mais aussi la réduction de la vente d’armes avec l’affectation des économies relatives au développement des peuples et « un système de contrôle de la consommation d’énergie, capable de décourager le développement des modes de production et de consommation qui se sont révélés destructeurs de la nature et des sociétés ».
Avec la mondialisation, l’hégémonie n’est plus possible !
Authors: Badie Bertrand , Dessendier Emmanuel 
Published: May 2019

Auteur d’un ouvrage intitulé Quand le Sud réinvente le monde. Essai sur la puissance de la faiblesse 1 , Bertrand Badie aborde les enjeux de pouvoirs mondiaux dans une optique à contre-courant de celle couramment médiatisée qui va de la vindicte aux louanges béates de la mondialisation. Si son propos semble parfois dissocier des faits que nous considérons liés en tant que conséquences du mode de production capitaliste mondialisé – comme la paupérisation pour le plus grand nombre qui accompagne les concentrations de richesses entre de moins en moins de mains et la montée de mouvements politiques identitaires –, il montre néanmoins que, très loin d’être le problème, la mondialisation est au cœur d’une gouvernance alternative du monde.
Le Grand Partage
Authors: Descola Philippe 
Published: May 2019

L’ouvrage de Philippe Descola, Par-delà nature et culture , dont nous présentons quelques extraits de son épilogue 1 , a été une puissante remise en question du « grand partage » que la modernité occidentale a produit entre nature et culture. En s’appuyant sur des exemples abondants en ethnographie, il a montré que de nombreuses sociétés ont su vivre et vivent en interaction avec la nature et que leurs activités quotidiennes ne pouvaient être disjointes de celle-ci. À l’aune des débats actuels en écologie, les analyses et les propositions théoriques de cet ouvrage viennent (ré)interroger notre rapport à la nature et nous invitent à (re)penser la relation que notre modernité occidentale entretient avec les non-humains.
Se réapproprier la protection de la nature
Authors: Chopot Antoine 
Published: May 2019

Comment œuvrer au rapprochement entre protection de la nature et construction politique de l’autonomie ? Cet article entrevoit la possibilité de cette rencontre, nourri par quelques expériences de terrain à la coopérative Longo Maï, l’un des projets d’autonomie collective les plus anciens en France, voire en Europe (depuis 1973), ainsi qu’à la ZAD de Notre-Dame-des-Landes, lors de sorties avec des occupants et des membres des « naturalistes en lutte ». À quelles conditions la protection de la nature rejoint-elle la prise en charge de nos vies et vice versa ?
« Je t’aime – Moi non plus »
Authors: Lauwers Margot 
Published: May 2019

Convergence des pensées et pratiques du féminisme et de l’écologie, l’écoféminisme a dû surmonter les soupçons d’« essentialisme » qui le renvoyaient aux figures de la Femme et de la Nature reproductrices. Né en France mais resté longtemps sous le boisseau, le vocable avait déjà trouvé une expression concrète aux États-Unis. Participant d’un renouveau en France des études sur l’écoféminisme, Margot Lauwers, auteure d’une thèse sur les manifestations littéraires de l’écoféminisme contemporain (2014), brosse un tableau historique et intellectuel de ce courant de pensée promis à s’approfondir et à enrichir de ses valeurs sensibles et « corporelles » l’écologie politique.
Internet, un espace politique
Authors: Bortzmeyer Stéphane 
Published: May 2019

Ingénieur spécialiste en réseaux informatiques, fin connaisseur de l’infrastructure de l’Internet, Stéphane Bortzmeyer aborde les questions politiques qui lui sont propres à partir de son fonctionnement technique. Il aide à nous défier des divagations sensationnalistes que l’on rencontre dans la presse et sur lesquels bon nombre d’entre nous se fondent malheureusement pour se faire une opinion sur ces sujets. Dans son récent livre, Cyberstructure 1 , dont nous reproduisons une partie de la conclusion, il rend particulièrement accessible à tous les utilisateurs de l’Internet – au-delà des spécialistes de la technique – la compréhension de ces enjeux politiques : du rôle des puissants GAFA (Google, Amazon, Facebook et Apple) à l’espionnage pratiqué par les États sur les communications numériques, en passant par le partage des œuvres culturelles et la rémunération des auteurs.
Eenvoudig personenvennootschapsrecht
Authors: Stokkermans Chr.M. 
Published: May 2019

Eenvoudig personenvennootschapsrecht
Het recente ambtelijk voorontwerp tot modernisering van het personenvennootschapsrecht geeft te veel complexiteit. Dit komt vooral door het ontbreken van een vennootschapstype zonder rechtspersoonlijkheid en een volwaardig alternatief voor de LLP. Daarnaast kan meer bij het algemene vermogensrecht worden aangesloten, zoals bij de vormgeving van vruchtgebruik en pandrecht op vennootschapsaandelen.

Effect of Agricultural Sector Expenditure on Nigeria’s Economic Growth
Authors: Akanbi O. O. , Onuk E. G. , Umar H. S. 
Published: May 2019

The study examined the Effect of Government Agricultural Expenditure on Nigeria’s Economic Growth. Time series data (1981–2015) were generated from the Central Bank of Nigeria and the National Bureau of Statistics. Descriptive Statistics and Vector Error Correction Model were used for data analysis. A unit root test was carried out to ascertain the stationarity of the series. Johansen co-integration test was also carried out to establish co-integration status of the variables in the model. For valid inference, estimated coefficients were subjected to normality, autocorrelation, heteroskedasticity and dynamic stability tests. The null hypotheses in relation to the respective tests statistic could not be rejected at 5% level of significance. The negative sign and statistical significant of Error Correction term of the VEC model, further confirmed the existence of co-integrating relationship among the variables in the model. The descriptive statistics result shows that, for almost a decade, public spending on agriculture consistently decline and was below the 10% benchmark of the Maputo declaration. The estimated VECM results showed that on the long-run, only the coefficient of Government Agricultural Expenditure variable influenced the economic growth, which was proxy by National GDP. This influence was positive and statistically significant at 5% probability level. However, on the short run, the result showed that both coefficients of Government Agricultural Expenditure variable and that of agricultural output were both positive and statistically significant in influencing the economic growth (GDP) at 5% probability level. Hence, since government expenditure has positive and significant effect on economic growth both on the short run and long run, it is recommended that government should review upward agricultural expenditure to stimulate growth in Nigerian economy, which could trigger more employment opportunity, increase per capita income, improved agricultural sector infrastructural deficit and reduce poverty.

Authors: Sasongko Setia Budi , Djaeni Mohamad , Utari Febiani Dwi 
Published: May 2019

This research studied the effect of drying temperature on the kinetic of degradation anthocyanin in roselle extract drying with foam under dehumidified air at temperatures ranging 40-60 oC. During the drying process, the anthocyanin content in the roselle extract was observed every 20 minutes for 120 minutes. The data was used for estimating the kinetic parameters of anthocyanin degradation namely constant of anthocyanins degradation rate and reaction order. The kinetic parameters were estimated and fitted with experimental data at various drying condition. Result showed that the anthocyanins degradation closed to the second order reaction. Meanwhile, the constant of anthocyanins degradation rate at various drying temperatures followed Arhenius correlation. With the result, retention of anthocyanin during the drying can be well estimated for various drying time and temperature.

Published: May 2019

The adipic acid (AA), important precursor for Nylon production, was synthesized from cyclohexanoneoxidation by two ways, microwaves irradiation and conventional method (under reflux) using H3PMo12O40 heteropolyacid as catalyst in the presence of hydrogen peroxide. In the order to increase the AA yield, several parameters as cyclohexanone/catalyst ratio, H2O2 concentration, solvent nature (H2O, CH3CO2H, and CH3OH, CHCl3 and CH3CN) and cyclohexanol addition to cyclohexanone were examined. For both activation modes, the highest AA yields are of 26-28%. Whereas, with microwaves irradiation, the time gain is much more attractive 30 min compared to 20 h.

Published: May 2019

Lithium-ion batteries (LIBs) are favorable power source devices at the last two decades, owing to high energy density, rechargeable, long life cycle, portable, safe, rechargeable, good performance and friendly environment. To support their development, in this research has been successfully prepared polymer electrolyte membrane, a main component of LIBs, based on 1-ethyl-3-methylimidazolium acetate ([EMIm]Ac) ionic liquid-plasticized methyl cellulose/lithium perchlorate (MC/LiClO4). [EMIm]Ac ionic liquid was easy synthesized by metathesis reaction between 1-ethyl-3-methylimidazolium bromide ([EMIm]Br) ionic liquid and potassium acetate (CH3COOK) at ambient temperature, for 1 hour. [EMIm]Ac ionic liquid was functional groups analyzed with Fourier Transform Infra-red (FT-IR) and structural analyzed with 1H-Nuclear Magnetic Resonance (NMR) and 13C-NMR. [EMIm]Ac ionic liquid-plasticized MC/LiClO4 biopolymer electrolyte membrane was prepared by casting solution, with [EMIm]Ac ionic liquid content, 0, 5, 10, 15, 20, 25, and 30% (w/w). Effect of 15% (w/w) [EMIm]Ac ionic liquid incorporation to MC/LiClO4 showed the best condition and selected as the optimum condition with conductivity, tensile strength, elongation break, and thermal stability of 9.160×10-3 S.cm-1, 24.19 MPa, 36.43%, ~256 and ~370 ºC, respectively. These results confirm that [EMIm]Ac ionic liquid can plasticize biopolymer electrolyte membranes of MC/LiClO4 to be appealing performances to fulfill the LIB’s separator requirement.

The Optimised Statistical Model for Enzymatic Hydrolysis of Tapioca by Glucoamylase Immobilised on Mesostructured Cellular Foam Silica
Authors: Agustian Joni , Hermida Lilis 
Published: May 2019

Enzymatic hydrolysis of starches using free glucoamylase to reducing sugars have difficulties in recovering and recycling of the enzyme, hence immobilisation on inert supports were widely studied. However, effectiveness of the immobilised glucoamylase were merely observed only on soluble starches. It was considered a valuable thing to know performance of glucoamylase on Mesostructured Cellular Foam (MCF) silica in hydrolysing of tapioca. An optimised study on enzymatic hydrolysis of tapioca using glucoamylase on MCF silica (9.2T-3D) and its kinetics were described including justification of the predicted model as it was required to develop in large scale operations. Central Composite Design was used to model the process by studying effects of three factors on DE values after enzyme immobilisation. Immobilisation of glucoamylase on this support gave up to 82% efficiency with the specific activity of 1,856.78 U.g-1. Its used to hydrolysis of tapioca resulted DE values of 1.740-76.303% (w/w) where the highest DE was obtained at pH of 4.1, temperature of 70 ℃ and agitation speed of 140 rpm. The optimisation produced a polynomial quadratic model having insignificant lack-of-fit and low standard deviation, so that it was applicable and reliable in simulating the DE with only 0.80% of data were not described. Temperature affected the process highly, but the buffer pH, agitation speed and factorial interactions were considered not important. KM value for immobilised enzyme was better than the free glucoamylase, however, its reaction rate was slower than the free glucoamylase catalysis. Copyright © 2019 BCREC Group. All rights reserved

Authors: Ahmad Yusof Nurul Amira , Mat Zain Norashikin , Pauzi Norlin 
Published: May 2019

Nowadays, zinc oxide (ZnO) has attracted attention in research and development because of its remarkable antibacterial properties. Chitosan/ZnO nanoparticles were successfully synthesized via microwave heating. The objectives of this work were to investigate the effect of stabilizer, power heating and time heating on size of chitosan/ZnO nanoparticles and to determine antibacterial activity against pathogenic bacteria, where chitosan was used as a stabilizing agent. Chitosan/ZnO nanoparticles were analyzed by Fourier Transform Infra Red (FTIR), X-ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), and Zetasizer instrument. The power heating and time heating were varied from 400 to 800 Watt and 4 to 8 minutes, respectively. The presence of chitosan has role on preventing the nanoparticles from agglomeration by producing a milky solution of chitosan/ZnO nanoparticles without any suspensions. The increase of power and time heating improved the size of nanoparticles. The peak in FTIR spectrum at around 427 cm-1 was confirmed the existence of the ZnO phase. XRD patterns showed that the chitosan/ZnO nanoparticles materials were pure phase with average crystalline size is 130 nm. FESEM revealed that chitosan/ZnO nanoparticles were uniformly distributed with the mean value of size is 70 nm and spherical shaped. Further impact of power and time heating on the size of the chitosan/ZnO nanoparticles can be shown by a nanoparticles size distribution with the average of 30 to 90 nm. The results showed that chitosan/ZnO nanoparticles have displayed an antibacterial inhibition zone against Gram-positive S. aureus and Gram-negative E. coli which 16.0 and 13.3 mm, respectively. Chitosan/ZnO nanoparticles were synthesized in this work presented have potential application to prevent bacterial infections.

Published: May 2019

A low cost Activated Carbon (AC) was prepared by using waste tyres as raw material for the removal of 2-chlorophenol (2-CP). The AC adsorbent was prepared and activated by pyrolysis process at 900 ºC under constant nitrogen flow. The physical properties of the AC produced was characterized using X-ray Diffraction (XRD), Brunauer-Emmett-Teller (BET), Field Emission Scanning Electron Microscopy (FESEM), and Fourier Transform Infra Red (FTIR). The influence of initial adsorbate concentration, pH and adsorbent dosage on the removal of 2-CP in the batch-operational mode at ambient temperature were also investigated. The results obtained showed the AC presence of an amorphous carbon with high BET surface area and a total pore volume of 208 m2.g-1 and 0.5817 cm3, respectively. The highest adsorption capacity of 2-CP by the AC absorbent was achieved at an initial concentration of 10 mg.L-1, pH 5, and adsorbent dosage of 0.5 g in the first 10 min of contact time. This finding proves that the low cost-AC produced from waste tyres can be utilized for an effective removal of chemical plant wastewater containing toxic chlorine substances.

Synthesis of Enantioenriched 3‐Amino‐3‐Substituted Oxindoles by Stereoselective Mannich Reaction Catalyzed by Supported Bifunctional Thioureas.
Authors: Rodríguez‐Ferrer Patricia , Sanz‐Novo Miguel , Maestro Alicia , Andrés José M. , Pedrosa Rafael 
Published: May 2019

AbstractEnantioenriched 3‐amino‐3‐substituted oxindoles have been obtained by addition of different nucleophiles to N‐Boc ketimines derived from isatin catalyzed by chiral bifunctional supported thioureas. The Mannich reaction occurs with excellent enantioselection, but poor diastereoselection when prochiral nucleophiles were used. The supported catalyst were recovered and reused for five times without loss of activity. The mixture of diastereoisomers formed when a prochiral structure was used as nucleophile was converted into a single enantioenriched pyrazolyl derivative.magnified image
