Prediction of Binding Sites of Zinc Complex Using Experimental and Computational Modeling Approach
Authors: Lafta Fadhil , Ali Faliah Hasen , Jassim Salah Aldin 
Published: March 2017

The binding modes of a new zinc complex derived from 3-(5-bromo-2-hydroxybenzylideneamino)-2-(5-bromo-2-hydroxyphenyl)-2,3-dihydroquinazoline-4(1H)-one withdivalent zinc was studied using both experimental and computational chemistry. 1H NMR, IR, molar ratio and atomic absorption were used to predict the characterization of zinc complex. Hartree–Fock (HF) method was selected to determine the HOMO-LUMO gap of several possibilities of binding sites to describe the more stable structure which reflects the more possible coordination sites of ligand to Zn+2 ion. Good matching between theoretical and experimental results was found which concluded the tetra dentate behavior of the ligand.
Ludwik Fleck’s concepts slicing through the Gordian Knot of Serbian Archaeology
Authors: Milosavljević Monika 
Published: March 2017

This article delves into the work of a researcher group based around the Center for Theoretical Archaeology in Belgrade (2007 – present) and the path they have taken to establish a foundation for further archaeological development within Serbia. This process illuminates the conceptual tools Fleck originally formulated - thought collectives, thought style, proto-ideas – which have played a significant role in the deconstruction of the concept of scientific fact and in the historicization / socialization of the theory of knowledge. For the Serbian archaeological community, one of the most fiendish aspects has been the ever present correlation between the field and the construction of a national identity - an especially painful theme for the postwar Balkans whose borders are still imprecisely defined. Hence, this work pays special attention to long held beliefs of ethnicity, ethnogenesis and continuity, emanating from outdated racial anthropology, but unfortunately still held as fact in Serbian archaeology.
A Comparative Study on the Microstructure Evaluation of Thixoforged A356 and A380 Aluminium Alloys

Published: March 2017

Abstract
Semi-solid processes of aluminium alloys have been a focus of interest for many years. Thixoforging is a kind of forging process which is carried out in the semi-solid region of the alloy. Ingots used in thixoforging process cannot be produced by conventional ways; they must be prepared with different processing routes. In this study, low superheat casting (LSC) technique was used for ingot fabrication in thixoforging process. LSC can be summarized as the pouring of molten metal at a temperature very close to liquidus followed by rapid solidification. Low heat input combined with sudden cooling suppresses dendritic growth and the conventional casting structure converts into a more spherical structure. A356 and A380 are well-known casting aluminium alloys which are commonly used in sand and die casting processes. These alloys are appropriate for semi-solid process and there are many applications that researches have been carried out in time. In view of that, A356 and A380 alloys were selected as subject of this comparative study and final structures were evaluated together. A LSC combined thixoforging process was successfully applied to both alloys and a spherical microstructure was obtained. High sphericity with a simple microstructure is the characteristic of the A356 alloy. A380 shows relatively lower sphericity with more complex microstructure which has numerous different intermetallic compounds.
Effect of Flow Induced Orientation of Carbon Nanotubes on the Capillary Extrusion Behavior of Low-Density Polyethylene
Authors: Uematsu H. , Natsuume T. , Tanoue S. , Iemoto Y. 
Published: March 2017

Abstract
The effect of carbon nanotubes (CNTs) on the capillary extrusion behavior of low-density polyethylene (PE) was investigated. From the linear viscoelasticity and the morphology observation, it was found that the CNTs were well dispersed throughout the PE matrix and our system belonged to the semi-dilute regime. The strain hardening, which quantifies the extension of the PE chain, decreased by presence of CNTs in the uniaxial elongational deformation. In contrast, the normal stress difference was almost unaffected by CNTs in the shear deformation. The capillary extrusion behavior revealed that swell ratio decreased with increasing the CNT content although melt fracture was promoted. We summarize that the suppression of swell and promotion of melt fracture are attributable to the orientation of CNTs.
Bio-Based Hybrid Polymers from Vinyl Ester Resin and Modified Palm Oil: Synthesis and Characterization
Authors: Fakhari A. , Rahmat A. R. , Wahit M. U. , Arjmandi R. 
Published: March 2017

Abstract
A series of bio-based hybrid thermosets composed of maleinated acrylated epoxidized palm oil (MAEPO) and vinyl ester resin (VE) were produced using free radical-induced crosslinking. The amount of petroleum-based resin which was replaced by bio-resin (MAEPO) was varied from 5 to 20 wt%. The structure of the polymer systems was investigated by scanning electron microscopy and dynamic mechanical analysis. The mechanical properties of the VE/MAEPO resins were studied using tensile, flexural and impact tests. The result obtained from structural analysis revealed that for the polymer hybrids with up to 20 wt% bio-resin content, there is good compatibility between MAEPO and VE as no phase separation was observed for these systems. The prepared eco-friendly bio-based thermosetting resins exhibit remarkable improvement in toughness parameters, such as ductility and impact strength, thereby showing potential for use in composites and nanocomposites applications.

Authors: Chandran V. G , Waigaonkar S. D. 
Published: March 2017

Abstract
This paper deals with investigations of rotational molding of LLDPE – Fumed Silica (FS) nano composites. The investigations were conducted at an industrial scale using a three arm biaxial rotational molding machine by carefully monitoring the Internal Air Temperature (IAT) within the mold. The effect of 4% FS on powder flow quality (dry flow and bulk density), melt flow quality (Melt Flow Index (MFI), static mechanical properties (tensile strength, modulus, toughness, flexural strength and impact strength) as well as dynamic mechanical properties (storage and loss modulus), along with creep and relaxation were investigated. Morphological studies were conducted to correlate the above findings with the dispersion of the nano particles within the LLDPE matrix.
Improved Layer Mechanical Properties of Micro Injection Molded PP
Authors: Ma S. J. , Wang S. W. , Zhang Q. , Li Q. 
Published: March 2017

Abstract
The results have been achieved by adjusting the structure to improve the performance of micro injection molded isotactic polypropylene products. Annealing was adopted to optimize the performance of isotactic polypropylene micro injection molded gears. It was found that the annealing temperature shows greater influence on the crystalline structure of the micro injection molded gears than annealing time. The layer mechanical properties were greatly improved after annealing, about 1.7-fold for modulus and 1.9-fold for hardness of the micro injection molded gears relative to the unannealed sample. This is due to the fact the state of molecular chain aggregation tends to be consistent after high temperature annealing in the micro injection molded isotactic polypropylene gear sample.
CT-guided selective percutaneous radiofrequency thermocoagulation via the foramen rotundum for isolated maxillary nerve idiopathic trigeminal neuralgia

Published: March 2017

OBJECTIVEAlthough CT-guided selective percutaneous radiofrequency thermocoagulation (PRFT) via the foramen rotundum (FR) has been used in the clinic as a novel successful treatment for isolated, second division (maxillary nerve [V2]), idiopathic trigeminal neuralgia (ITN), there is only very limited related literature published to date. This report aims to provide more detail for physicians about this technique.METHODSBetween March 2013 and April 2014, 20 patients with isolated V2 ITN refractory to or intolerant of drug treatment were treated by CT-guided selective PRFT via the FR at the First Affiliated Hospital of Nanchang University. The outcome of pain relief was assessed using the Barrow Neurological Institute (BNI) pain score, and grouped as good (BNI Class I or II, no medication required) and bad (BNI Class III–V, medication required or failed). Recurrence was defined as a relapse to a previous lower level after attainment of any higher level of pain relief. Adverse effects and complications were also monitored and recorded.RESULTSAll patients (100%) obtained good pain relief including BNI Class I in 17 patients (85%) and BNI Class II in 3 patients (15%) immediately postoperatively. None of the patients were lost to follow-up. During the mean follow-up period of 24.3 months (range 18–30 months), 2 patients (10%) experienced recurring pain and the mean time until recurrence was 10.5 months (range 8–13 months). No adverse effects or complications occurred except for transient numbness restricted to the V2 dermatome in all patients (100%) and facial hematoma in 3 patients (15%).CONCLUSIONSIn the current study, CT-guided selective PRFT via the FR not only achieved absolute selective lesioning to V2, but also helped patients attain successful pain relief with few adverse effects. These limited data suggest that CT-guided selective PRFT via the FR appears to be a feasible, safe, effective, and even relatively ideal treatment for isolated V2 ITN, but these findings need confirmation from further studies.
Rhizome extracts of <i>Acorus odoratus</i>: Antifungal, anti-yeast, anti-oxidant and HPLC quantification
Authors: Khan Bilal Muhammad , Bakht Jehan , Khan Wajid 
Published: March 2017

<p class="Abstract">Different extracts from the rhizomes of <em>Acorus </em>odoratus were assessed for the presence of antifungal, anti-yeast and anti-oxidant potential. Mild antifungal and robust anti-yeast potential were revealed by the tested samples. A gigantic anti-oxidant activity, however, was noted for all extracts at each concentration used. The data further revealed that n-butanol and ethyl acetate fractions measured fair antifungal (41.5% inhibition against Rhizopus oryzae and 36.2% inhibition against<em> Acremonium </em>alternatum at 2000 µg/well respectively), and highest anti-yeast (70.3 and 66.8% activities respectively at 2000 µg/disc) and anti-oxidant (95.8 and 97.9% activities respectively at 250 ppm) potential while samples extracted with water were least potent. Furthermore, both n-butanol and ethyl acetate were found as the best extraction solvents for antifungal, anti-yeast and anti-oxidant compounds (particularly gallic acid) from the rhizomes of <em>A. </em>odoratus in HPLC analysis.</p><p> </p>
The Kinematics of the Permitted C ii λ6578 Line in a Large Sample of Planetary Nebulae*

†

Published: March 2017

Abstract
We present spectroscopic observations of the C ii
λ6578 permitted line for 83 lines of sight in 76 planetary nebulae at high spectral resolution, most of them obtained with the Manchester Echelle Spectrograph on the 2.1 m telescope at the Observatorio Astronómico Nacional on the Sierra San Pedro Mártir. We study the kinematics of the C ii
λ6578 permitted line with respect to other permitted and collisionally excited lines. Statistically, we find that the kinematics of the C ii
λ6578 line are not those expected if this line arises from the recombination of C2+ ions or the fluorescence of C+ ions in ionization equilibrium in a chemically homogeneous nebular plasma, but instead its kinematics are those appropriate for a volume more internal than expected. The planetary nebulae in this sample have well-defined morphology and are restricted to a limited range in Hα line widths (no large values) compared to their counterparts in the Milky Way bulge; both these features could be interpreted as the result of young nebular shells, an inference that is also supported by nebular modeling. Concerning the long-standing discrepancy between chemical abundances inferred from permitted and collisionally excited emission lines in photoionized nebulae, our results imply that multiple plasma components occur commonly in planetary nebulae.
« Notre devoir envers la science ». Médecines humaine et animale dans la guerre de Sécession, 1861-1865
Authors: Meier Kathryn Shively 
Published: March 2017

La guerre de Sécession américaine transforma la communauté médicale américaine du Nord, celle du Sud en proie à la pénurie, ainsi que la médecine vétérinaire à l’époque sous-développée. Elles adoptèrent des approches communes associées à « l’école de Paris » de médecine clinique. Les circonstances de la guerre firent s’élargir le champ d’intervention des médecins et des vétérinaires (élites diplômées ou ruraux ayant été formés sur le terrain), pour y intégrer des approches scientifiques et sanitaires alternatives qu’ils avaient été nombreux à refuser catégoriquement avant la guerre. Ces évolutions furent à la fois délibérées et fruits des circonstances, tout en étant facilitées par le contexte militaire. Les médecins les plus influents, formés à l’étranger avant la guerre et déjà acculturés aux pratiques scientifiques, obligèrent les chirurgiens du rang à adopter de nouvelles techniques. Par ailleurs, l’urgence et l’ampleur des problèmes, ainsi que les privations causées par la crise sanitaire de guerre, les encouragèrent à improviser et accepter de nouvelles méthodes. Les officiers chirurgiens et vétérinaires bénéficiaient d’une protection professionnelle due à leur rang et d’une population de patients captive et obéissante. La guerre a donné le jour à un ensemble de pratiques médicales, sous l’enseigne de la science, et a contribué à la revendication d’une nouvelle identité professionnelle. Ces évolutions de la médecine humaine et vétérinaire ont survécu à la guerre, dont témoignent des publications, des associations professionnelles et des instituts de formation.
Égalité ou supériorité ?
Authors: Brice Benjamin 
Published: March 2017

Résumé L’étude de la reconnaissance dans les relations internationales permet de contester le modèle dominant de l’acteur cherchant de manière « rationnelle » à maximiser ses intérêts matériels (sécurité et profit). Cependant, ces nouvelles recherches se concentrent avant tout sur la « reconnaissance-égalité », c’est-à-dire sur le désir qu’ont les acteurs collectifs d’être reconnus par les autres comme des égaux. Ces approches mettent donc de côté la « reconnaissance-supériorité », c’est-à-dire la volonté d’être reconnu comme supérieur aux autres. Or, même si cette dernière motivation apparaît comme normativement problématique, il n’est pas évident qu’elle disparaisse de l’horizon de la vie internationale. Après avoir rappelé l’apport des réflexions sur la reconnaissance dans les études internationales et la manière dont cette nouvelle orientation s’est concentrée principalement sur la « reconnaissance-égalité », nous évoquerons quelques pistes pour aborder le phénomène de la « reconnaissance-supériorité » grâce à des suggestions anthropologiques et empiriques.
L’œuvre d’amour à l’époque de sa reproductibilité technique
Authors: Braunstein Néstor A. 
Published: March 2017

Le corps réel du « parlêtre » ne cesse d’être transformé par l’addition de nouveaux organes : prothèses, appareillages, « lathouses ». Les composants organiques du corps sont remplacés par des éléments cybernétiques et ce processus nous transforme en cyborgs. Quelles sont les implications d’un tel changement dans le champ de l’amour et celui de la psychanalyse, dont le levier fondamental est l’amour, dans la mesure où, comme l’affirme Lacan, l’amour est un fait culturel ? Pouvons-nous soutenir avec Walter Benjamin que l’œuvre d’amour s’apparente à celui de l’art (tekhné) ? Une telle hypothèse supposerait que le couple évolue en fonction de la reproductibilité mécanique et du clonage des organes techniques du langage qui l’unit. Cette hypothèse mérite d’être étudiée.
Le cas du patient G : traumatisme cérébral, psychose et psychanalyse
Authors: Caine Diana 
Published: March 2017

À 28 ans, le patient G a été admis pour traumatisme crânien à la clinique où je travaille. Il se plaignait de l’impact sur sa vie du traumatisme cérébral subi à l’âge de 13 ans et de voix persécutrices. Cette crise est survenue alors que ses études universitaires prenaient fin, sa petite amie japonaise était retournée chez elle, et sa mère, avec laquelle il avait toujours vécu, l’avait laissé pour vivre ailleurs. L’évaluation neuropsychologique a constaté les déficits cognitifs que l’on rencontre habituellement après un traumatisme cérébral : usage concret du langage, capacité limitée à former des plans, etc. L’intervention psychanalytique a décelé une intense anxiété quant à la question de savoir s’il devait ou non épouser sa petite amie. Cet exposé aborde deux méthodes très différentes d’approche de la détresse psychologique de ce jeune homme. Si les deux approches permettent de dire que sa réflexion est concrète, que son usage du langage n’inclut pas la dialectique, qu’il manque d’empathie, qu’il a des difficultés à formuler des plans et à les exécuter, ce que la psychanalyse, elle, met en avant, c’est la possibilité de travailler avec l’expérience subjective singulière de ce patient, en tenant compte de la place du traumatisme neurologique dans son histoire.
Naturalisations : deuil et violence coloniale
Authors: Chaffel Boris 
Published: March 2017

Ce texte, en problématisant l’usage du terme de « naturalisation » dans le roman de Yoko Ogawa, L’annulaire , depuis son interprétation littérale par Jean Allouch, met en évidence que la polysémie des usages de « naturalisation », en français, fait symptôme, en nouant bizarrement l’opération du deuil et la violence coloniale. Le récit d’Éric Vuillard, Tristesse de la terre , qui explore la colonisation depuis le Wild West Show de Buffalo Bill et la naissance du spectacle de masse aux États-Unis, permet une interprétation de ce symptôme, en dégageant une hantise, coextensive d’une violence archivale. En creux, la fonction de l’archive – ou de son impossibilité – dans le deuil, qui convoque deux modalités de la naturalisation. On opposera ainsi, d’une part, une naturalisation-extorsion dans la violence coloniale, qui tient à une extorsion de l’objet d’amour au service d’un Récit instituant la transparence persécutrice du tout-Autre, privant l’endeuillé a priori de la possibilité du deuil ; d’autre part, la naturalisation comme produit de l’opération dégagée par la lecture de L’annulaire proposée par Jean Allouch, qui trouve un écho dans le final du livre d’Éric Vuillard. Ce tressage rencontre la voie ouverte par certains auteurs postcoloniaux, qui promeuvent l’opacité comme lieu de subjectivation de la violence du si transparent Récit colonial.

<p><em>Moringa oleifera</em> (MO) belongs to the family <em>Moringaceae</em> and is native to tropical Africa. It exhibits many therapeutic properties and has been widely cultivated because of the high food value of the leaves, fruit, flowers and roasted seeds. It possesses high quality protein, calcium, iron, fiber, minerals and essential amino acids. The objective of this study was to evaluate the effects of MO flour in anthropometric and biochemical profile of Wistar rats. Animals were divided randomly into the following groups (n=10): G1 (control group) and G2 (treated with MO flour mixed to the rat food) were both treated for 40 days and G3 (control group), G4 (treated with senne) and G5 (treated with MO flour) were studied to evaluate the intestinal motility. After 40 days, animals of G1 and G2 were euthanized and evaluation of glycaemia, total cholesterol, triglycerides, LDL-c, VLDL-c, HDL-c, C reactive Protein (PCR), hepatic enzymes, Lee Index, weight and visceral fat were performed. Our results showed reduction of visceral fat, total cholesterol, triglycerides, LDL-c, and VLDL-c and increase in the HDL-c levels. No significant differences were found in the body weight, glycaemia, hepatic enzymes and PCR. The MO flour also promoted laxative effects similar do senne. Our results with the use of <em>Moringa oleifera</em> flour are very promising, once its use improved lipid profile, prevented weight gain and showed no adverse effects. Thus we may conclude that this flour could be added to industrial products in order to provide healthier products to the consumers.</p><p> </p>

<p>The present study aims at comparing <em>in-vitro </em>scavenging activities of methanol extract and fractions of <em>Lophira lanceolata</em> leaves, and also to study the oral acute toxicity of the ethyl acetate fraction.</p><p>Petroleum ether, dichloromethane, ethyl acetate, butanol and water fractions were prepared from the methanol extract of the plant. The scavenging activity of DPPH (2, 2-Diphenyl-1-picrylhydrazyl), the total phenolic (TPC) and total flavonoid (TFC) contents of the extract and fractions were determined by spectrophotometrical methods using gallic acid (GA) and quercetin (Qu) as reference antioxidant. The fifty percent inhibitory concentration (IC<sub>50</sub>), fifty percent effective concentration (EC<sub>50</sub>) and the antiradical power (ARP) were determined for all extract and fractions. An acute toxicity study using a single oral dose of 5000 mg/kg of the ethyl acetate fraction of the plant was conducted in female Albino rats following the OECD (420) Guidelines. Blood samples were collected for hematological and biochemical analysis. Histopathological examinations of the heart, kidney and liver were performed.</p><p>The results showed that the ethyl acetate fraction of <em>L</em>.<em> lanceolata</em> had the highest free radical scavenging activity of DPPH (IC<sub>50</sub>=1,43; EC<sub>50</sub>= 0.07 and ARP = 14,28) and also contain the highest amount of total phenols (14,4±0,02 mg of GA equivalent/g of plant fraction) and total flavonoids (93,3±0,04 mg of Qu equivalent/g of plant fraction) as compared to other fractions and ascorbic acid (IC<sub>50</sub>=5,82; EC<sub>50</sub>= 3.44; ARP=3,44). The hematological parameters and the lipid profile didn’t show any major change compared to the control group. However, a significant increase of aspartate aminotransferase (AST, p&lt;0.001) and alanine aminotransferase (ALT, p&lt;0.001) showed that the ethyl acetate fraction of the methanol extract of <em>L</em>.<em> lanceolata </em>leaves might not totally be safe for consumption, in the conditions of our experiment.</p>
