« Escribir de muertos » : Juan Hernández Luna de Crónica de la violencia política à Domada furia
Authors: Rutés Sébastien 
Published: March 2015

Le Parti de la Révolution mexicaine (PRD) avait été fondé en 1969, après la défaite électorale de Cuauthémoc Cárdenas, candidat du Front Démocratique national (FND) aux élection présidentielles du Mexique. En 1996, un nombre élevé de ses militants (504) avaient été assassinés. La Fondation Ovando y Gil, créée en mémoire du premier militant tué, se donnait pour tâche de maintenir vivant le souvenir des victimes de ces crimes politiques. Juan Hernández Luna, jeune écrivain et membre du PRD, s’est alors vu confier la responsabilité d’écrire ce mémoire et a rassemblé les circonstances de ces morts et les témoignages des membres de leurs familles dans plusieurs des États du pays (ceux de Puebla et de Guerrero notamment), fondement de son livre Para que no se olvide… Crónica de la violencia política (1997) ainsi que d’un roman, Domada furia (resté inédit après le décès prématuré de l’auteur en 2010). La comparaison des deux livres fait ressortir la spécificité des écritures en fonction de l’action politique et de la conservation de la mémoire vue comme finalité proprement littéraire. Cela va du bilan de la criminalité politique au Mexique, établi dans le premier livre, à la mise en œuvre des témoignages, côte à côte avec les fiches, et l’utilisation des uns et des autres en scènes de la vie locale, à caractère hybride, contribuant à la structuration du récit. Les effets sont parallèles pour les deux livres : carnet de voyage à travers un Mexique rural fait de misères et d’injustices, dénonciation et, dans le roman, une fiction de vengeance qui vient donner une compensation aux souffrances des victimes.
Crimes en trois lignes ou la possibilité d’un roman
Authors: Franco Marie 
Published: March 2015

Durant son exil mexicain, l’Espagnol Max Aub publie en 1956 un ensemble de textes brefs, Crímenes ejemplares, qui présentent à la première personne les causes et les modalités de divers crimes, absurdes, grotesques ou horribles. Le pourquoi et le comment dessinent une typologie variée où prédominent l’ironie et l’humour noir, la violence et l’autojustification cynique. Ce système, fondé sur les potentialités narratives du fragment elliptique et sur un apparent nihilisme, recèle en réalité une vocation moraliste, fruit d’une double inspiration : le récit criminel et l’aphorisme moral.
La mémoire ou l’oubli du crime : trous du dire dans El Llano en llamas
Authors: Olivier Florence 
Published: March 2015

Les nouvelles de El Llano en llamas rassemblent les récits d’une violence généralisée qui ne parvient pas à se constituer en histoire, et dont le dire individuel hésite entre la mémoire et l’oubli, en devenir, pour un temps suspendu. S’il y a, dans la nouvelle qui donne son titre au recueil, trace de l’histoire de la révolution, elle est substituée par la mémoire du crime collectif d’une bande d’hommes en armes. El Llano en llamas, le recueil, remplace le récit de l’histoire par des histoires de crimes ou de catastrophes, dans un univers dominé par une désillusion qu’aucun personnage ne saurait qualifier du vain mot de « politique ». Si la révolution ne laisse d’autres traces qu’un récit factuel au plus près des souvenirs d’un combattant puni de prison pour des crimes de droit commun, que dire de la vie ordinaire ou, pour ainsi dire, de l’ordinaire du crime ? Ce qui fait parfois trace mais difficilement sens pour les narrateurs, ce qui parvient approximativement à faire date, à marquer leur temps de vie de l’entaille d’un événement, c’est le crime subi, commis, ou vu. Or si, dans ce monde de violence, l’on s’efforce de se rappeler et donc si l’on tente de faire tenir par le souvenir sa propre version d’une histoire, c’est dans la nécessité de la trace, dans le besoin de trouver une position tenable par rapport à l’acte, de se savoir sujet, ou pas, de l’action.Ainsi, dans trois des nouvelles de El Llano en llamas, ces récits d’hommes, criminels conscients ou inconscients de leur acte, innocents injustement accusés, ou tour à tour innocents et criminels, tournent-ils autour de la dérobade du sens de leurs actes, car la loi pénale, la Loi divine, la loi de la coutume ne coïncident pas, elles ne statuent rien qui garantisse la justice à l’un ou à l’autre, elles n’accordent aucune valeur de justesse aux paroles des incriminés. Les trous de mémoire, redoublés par les trous du récit dans « En la madrugada », qui ne corroborent ni n’infirment ce qui ne peut être su de la responsabilité d’Esteban, laissent apparaître le seul tourbillon de la violence homicide, de même que le montage temporel de « El hombre », tandis que le souvenir aigu qu’a gardé le narrateur de « la Cuesta de las comadres » du meurtre qu’il a commis ponctue seulement une histoire d’abus qui le dépasse. Les récits, constats ou dépositions de ces violences appelant la violence, où nul ne saurait être sujet de ses actes, où le dire s’avance au-dessus des trous du sens, demeurent en souffrance.
Collecter ou collectionner des jouets par de sombres temps : Eugénie Goldstern et Walter Benjamin
Authors: Le Bouar Françoise 
Published: March 2015

Faire entrer en résonance la collecte de jouets d’Eugénie Goldstern, ethnologue de l’arc alpin dont on redécouvre aujourd’hui l’œuvre, et les multiples achats effectués par Walter Benjamin tout au long de son séjour à Moscou permettra de dégager quelques pistes pour tenter de répondre à la question : pourquoi s’intéresser ainsi aux jouets d’enfants ? Qu’est-ce qui justifie un tel engagement scientifique chez l’une, qu’est-ce qui donne une tournure obsessionnelle aux recherches de l’autre, apportant à leur collecte à tous deux, en plus d’un aspect passionné, un caractère d’urgence, et ce, aux lendemains de crises qui ont bouleversé l’Europe du début du xxe siècle ?

Authors: Mangusan Ralph Francis , Hooper Vallire , Denslow Sheri A. , Travis Lucille 
Published: March 2015

BackgroundDelirium after surgery is a common condition that leads to poor outcomes. Few studies have examined the effect of postoperative delirium on outcomes after cardiac surgery.ObjectivesTo assess the relationship between delirium after cardiac surgery and the following outcomes: length of stay after surgery, prevalence of falls, discharge to a nursing facility, discharge to home with home health services, and use of inpatient physical therapy.MethodsElectronic medical records of 656 cardiac surgery patients were reviewed retrospectively.ResultsPostoperative delirium occurred in 161 patients (24.5%). Patients with postoperative delirium had significantly longer stays (P &lt; .001) and greater prevalence of falls (P &lt; .001) than did patients without delirium. Patients with delirium also had a significantly greater likelihood for discharge to a nursing facility (P &lt; .001) and need for home health services if discharged to home (P &lt; .001) and a significantly higher need for inpatient physical therapy (P &lt; .001). Compared with patients without postoperative delirium, patients who had this complication were more likely to have received zolpidem and benzodiazepines postoperatively and to have a history of arrhythmias, renal disease, and congestive heart failure.ConclusionsPatients who have delirium after cardiac surgery have poorer outcomes than do similar patients without this complication. Development and implementation of an extensive care plan to address postoperative delirium is necessary for cardiac surgery patients who are at risk for or have delirium after the surgery.

Published: March 2015

BackgroundWeaning from mechanical ventilation to spontaneous breathing is associated with changes in the hemodynamic and autonomic nervous systems that are reflected by heart rate variability. Although cardiac dysrhythmias are an important manifestation of hemodynamic alterations, the impact of heart rate variability on the occurrence of dysrhythmias during weaning has not been specifically studied.ObjectivesTo describe differences in heart rate variability spectral power and occurrence of cardiac dysrhythmias at baseline and during the initial trial of weaning from mechanical ventilation and to evaluate the impact of heart rate variability during weaning on occurrence of dysrhythmias.MethodContinuous 3-lead electrocardiographic recordings were collected from 35 patients receiving mechanical ventilation for 24 hours at baseline and during the initial weaning trial. Heart rate variability was evaluated by using spectral power analysis.ResultsLow-frequency power increased (P = .04) and high-frequency and very-low-frequency power did not change during weaning. The mean number of supraventricular ectopic beats per hour during weaning was higher than the mean at baseline (P &lt; .001); the mean of ventricular ectopic beats did not change. Low-frequency power was a predictor of ventricular and supraventricular ectopic beats during weaning (P &lt; .001). High-frequency power was predictive of ventricular and supraventricular (P = .02) ectopic beats during weaning. Very-low-frequency power was predictive of ventricular ectopic beats (P &lt; .001) only.ConclusionHeart rate variability power spectra during weaning were predictive of dysrhythmias.

Fever in Trauma Patients: Evaluation of Risk Factors, Including Traumatic Brain Injury
Authors: Bengualid Victoria , Talari Goutham , Rubin David , Albaeni Aiham , Ciubotaru Ronald L. , Berger Judith 
Published: March 2015

Background
The role of fever in trauma patients remains unclear. Fever occurs as a response to release of cytokines and prostaglandins by white blood cells. Many factors, including trauma, can trigger release of these factors.

Objectives
To determine whether (1) fever in the first 48 hours is related to a favorable outcome in trauma patients and (2) fever is more common in patients with head trauma.

Method
Retrospective study of trauma patients admitted to the intensive care unit for at least 2 days. Data were analyzed by using multivariate analysis.

Results
Of 162 patients studied, 40% had fever during the first 48 hours. Febrile patients had higher mortality rates than did afebrile patients. When adjusted for severity of injuries, fever did not correlate with mortality. Neither the incidence of fever in the first 48 hours after admission to the intensive care unit nor the number of days febrile in the unit differed between patients with and patients without head trauma (traumatic brain injury). About 70% of febrile patients did not have a source found for their fever. Febrile patients without an identified source of infection had lower peak white blood cell counts, lower maximum body temperature, and higher minimum platelet counts than did febrile patients who had an infectious source identified. The most common infection was pneumonia.

Conclusions
No relationship was found between the presence of fever during the first 48 hours and mortality. Patients with traumatic brain injury did not have a higher incidence of fever than did patients without traumatic brain injury. About 30% of febrile patients had an identifiable source of infection. Further studies are needed to understand the origin and role of fever in trauma patients. (American Journal of Critical Care. 2015; 24:e1–e5)

We develop a direct approach to ûnding ground state solutions of Nehari–Pankov type for the above system. Our method is especially applicable to the case whenwhere with , and and hj(x, t) are nondecreasing in t ∊ ℝ+ for every x ∊ ℝN and gi(x, 0) = hj(x, 0) = 0.

On the Largest Dynamic Monopolies of Graphs with a Given Average Threshold
Authors: Khoshkhah Kaveh , Zaker Manouchehr 
Published: March 2015

AbstractLet G be a graph and let τ be an assignment of nonnegative integer thresholds to the vertices of G. A subset of vertices, D, is said to be a τ-dynamicmonopoly if V(G) can be partitioned into subsets D0 , D1, …, Dk such that D0 = D and for any i ∊ {0, . . . , k−1}, each vertex v in Di+1 has at least τ(v) neighbors in D0∪··· ∪Di. Denote the size of smallest τ-dynamicmonopoly by dynτ(G) and the average of thresholds in τ by τ. We show that the values of dynτ(G) over all assignments τ with the same average threshold is a continuous set of integers. For any positive number t, denote the maximum dynτ(G) taken over all threshold assignments τ with τ ≤ t, by Ldynt(G). In fact, Ldynt(G) shows the worst-case value of a dynamicmonopoly when the average threshold is a given number t. We investigate under what conditions on t, there exists an upper bound for Ldynt(G) of the form c|G|, where c < 1. Next, we show that Ldynt(G) is coNP-hard for planar graphs but has polynomial-time solution for forests.
Reorienting Smile: A Biological Approach

Published: March 2015

ABSTRACT
Tooth fragment reattachment offers a conservative, esthetic, and cost-effective restorative option that has been shown to be an acceptable alternative to the restoration of the fractured tooth with resin-based composite or full-coverage crown. Reattachment of intact natural tooth fragment is advantageous compared to crowns since color, morphology, translucency can be retained and treatment is immediate. This article describes a technique for the adhesive reattachment of an intentionally sliced central incisor with the goal of maximum esthetics in minimum time.

Kinetic Study on Catalytic Cracking of Rubber Seed (Hevea brasiliensis) Oil to Liquid Fuels
Authors: Rengga Wara Dyah Pita , Handayani Prima Astuti , Kadarwati Sri , Feinnudin Agung 
Published: March 2015

Reaction kinetics of catalytic cracking of rubber seed oil to liquid fuels has been investigated. The reac-tion was performed with sulfuric acid as catalyst at temperatures of 350-450 oC and the ratio of oil-catalyst of 0-2 wt.% for 30-90 minutes. Kinetics was studied using the model of 6-lump parameters. The parameters were rubber seed oil, gasoline, kerosene, diesel, gas, and coke. Analysis of experimen-tal data using regression models to obtain reaction rate constants. Activation energies and pre-exponential factors were then calculated based on the Arrhenius equation. The simulation result illus-trated that the six-lump kinetic model can well predict the product yields of rubber seed oil catalytic cracking. The product has high selectivity for gasoline fraction as liquid fuel and the smallest amount of coke. The constant indicates that secondary reactions occurred in diesel products compared to gaso-line and kerosene. The predicted results indicate that catalytic cracking of rubber seed oil had better be conducted at 450 oC for 90 minutes using 0.5 wt.% catalyst. © 2015 by Authors, Published by BCREC Group.

Authors: Rasyid Rismawati , Prihartantyo Adrianto , Mahfud Mahfud , Roesyadi Achmad 
Published: March 2015

This research was aimed to convert Calophyllum inophyllum kernel oil into liquid fuel through hydro-cracking process using non-sulfide CoMo catalysts. The experiment was carried out in a pressurized re-actor operated at temperature and pressure up to 350 oC and 30 bar, respectively. The CoMo catalysts used in the experiment were prepared by 10 wt.% loading of cobalt and molybdenum solutions over various supports, i.e. γ-Al2O3, SiO2, and γ-Al2O3-SiO2 through impregnation method. It is figured out from the experiment that non-sulfide CoMo based catalysts have functioned well in the hydrocracking conversion of Calophyllum inophyllum kernel oil into fuels, such as gasoline, kerosene, and gasoil. The CoMo/γ-Al2O3 catalyst resulted higher conversion than CoMo/SiO2 and CoMo/γ-Al2O3-SiO2. The fuel yields were 25.63% gasoline, 17.31% kerosene, and 38.59% gasoil. The fuels obtained in this research do not contain sulfur compounds so that they can be categorized as environmentally friendly fuels. © 2015 by Authors, Published by BCREC Group.

Published: March 2015

This study aims to produce reducing sugar hydrolyzed from substrate, coconut coir dust pretreated by recycled ionic liquid and its combination with alkaline. The 1H NMR and FTIR were performed to ver-ify the synthesized ionic liquid methylmethylimidazolium dimethyl phosphate ([mmim][dmp]). The structure of pretreated substrates was analyzed by XRD measurement. The used ionic liquid was recy-cled twice to re-employ for substrate pretreatment. The treated- and untreated-coconut coir dust were hydrolyzed into sugars using pure cellulase. The reaction, which called an enzymatic hydrolysis, was conducted at 60 °C, pH 3, for 48 h. The yields of sugar hydrolyzed from fresh IL-pretreated, 1R*IL-pretreated and 2R*IL-pretreated substrates were of 0.19, 0.15 and 0.15 g sugar / g cellu-lose+hemicellulose, respectively. Pretreatment with NaOH or the combination of NaOH+IL resulted in yields of reducing sugars of 0.25, 0.28 g/g, respectively. When alkaline combined with the recycled ionic liquids, NaOH+1R*IL, NaOH+2R*IL in the pretreatment, the yields of sugar were relatively similar to those obtained using alkaline followed by fresh ionic liquid. If the mixture enzymes, cellu-lase+xylanase, used to liberate sugars from fresh IL-pretreated, or recycled IL-pretreated substrates, the amount of sugar (concentration or yield) increased slightly compared to that employing a single cel-lulase. These findings showed that recycled IL pretreatment of the high-lignin lignocellulose, coconut coir dust, is a new prospect for the economical manufacture of fermentable sugars and biofuel in the coming years. © 2015 by Authors, Published by BCREC Group.

Synthesis of 4-tert-Butyltoluene by Vapor Phase tert-Butylation of Toluene with tert-Butylalcohol over USY Zeolite
Authors: Shen Yanming , Yuan Shan , Fan Lihui , Liu Dongbin , Li Shifeng 
Published: March 2015

Vapour phase tert-butylation of toluene with tert-butylalcohol was studied over ultra-stable Y zeolite (USY) catalyst. The effects of reaction temperature, toluene/TBA molar ratio and liquid space velocity on conversion of toluene and selectivity for 4-tert-butyltoluene were studied. The deactivation and regeneration of the catalyst was also investigated. The results showed that the USY zeolite catalyst offered better toluene conversion of about 30 % and 4-tert-butyltoluene selectivity of about 89 % at the suitable reaction condition as follows: reaction temperature of 120 oC, toluene/TBA ratio of 2:1 and liquid space velocity of 2 ml/g·h. The clogging of mocropores by the formed carbon or oligomers was the main reason for the deactivation of the catalyst. By combustion at 550 oC, the catalyst just lost about 5 % in toluene conversion and about 2 % in PTBT selectivity. © 2015 by Authors, Published by BCREC Group.

Application of Ionic Liquid [DMIM]DMP Pretreatment in the Hydrolysis of Sugarcane Bagasse for Biofuel Production
Authors: Widjaja Arief , Agnesty Silvya Yusnica , Sangian Hanny F. , Gunawan Setiyo 
Published: March 2015

Sugarcane bagasse is one of lignocellulose materials that can be converted to biofuel. This work was aimed to develop new pretreatment combination methods to process sugarcane bagasse lignocellulose into biofuel (bio-hydrogen). Pretreatment of sugarcane bagasse using NaOH solution in combination with ionic liquid [DMIM]DMP enhanced the enzymatic hydrolysis significantly. After the pretreat-ment, the content of cellulose and hemicellulose increased by 29.31% compared to the untreated one. Cellulose and hemicelluloses were used as raw materials to produce reducing sugars, that can be con-verted to bio-hydrogen via fermentation. After being subjected to combined pretreatment processes, the crystalline index of sugarcane bagasse decreased significantly compared to solely NaOH pretratment. This indicates a more amorphous structure of the sugarcane bagasse, which makes it is easier to be hy-drolyzed into reducing sugars. The recovery of cellulose + hemicellulose after pretreatment for 20 min and 120 °C was 92%, and the yield obtained was 0.556 g sugars/g (cellulose + hemicellulose) after 12 h and the bio-hydrogen yield was 0.46 mol H2/mol sugars consumed after 48 h fermentation. The use of recycled of ionic liquid showed similar performance compared to the use of fresh ionic liquid. © 2015 by Authors, Published by BCREC Group.
