Fatal pulmonary thromboembolism after prolonged physical immobilization in hospitalized psychiatric patients
Authors: Stefanovic Vesna , Kuzmanovic Ana , Stefanovic Slavisa
Published: October 2013

Background/Aim. Pulmonary thromboembolism (PTE) may be one of the causes of
sudden death in hospitalized psychiatric patients. The aim of our study was
to investigate whether fatal PTE in these patients may be the result of their
prolonged physical immobilization, particularly when there were associated
risk factors, and to emphasize the importance of this problem. Methods. A
retrospective analysis of medical records of psychiatric patients died
suddenly at the Department of Intensive Care of the Clinic of Psychiatry ?Dr
Laza Lazarevic?, Belgrade, in the period January 1, 2010 - December 31, 2011,
was performed. Data of those for which the autopsy showed PTE as the
immediate cause of death were extracted, and the presence of risk factors for
the development of deep vein thrombosis analyzed. Results. In the observed
period, out of 4,001 hospitalized psychiatric patients 53 died, and for 18 of
them autopsy was required due to sudden death. In five patients, autopsy
revealed PTE as a direct and sole cause of death. All the five patients were
males, mean age 45.2 years, and during hospitalization all received strong
antipsychotics and diazepam. Of the total duration of their hospital stay
(mean 8.2 days), they were temporarily immobilized during an average 4.2
days. Four of them had acute infection, three were active smokers, and the
two had a body mass index > 30 kg/m2. Conclusion. Our results suggest a
possible link between prolonged physical immobilization of psychiatric
patients who also receive antipsychotic therapy, and total PTE.

Published: October 2013

Introduction. Gestational trophoblastic diseases (GTD) are a spectrum of
tumors with a various of biological behavior and potential for metastases. It
consists of hydatiform mole, invasive mole, choriocarcinoma and placental
site trophoblastic tumor. Choriocarcinoma presents a very aggressive tumor
with high malignant potential. Case report. We presented the two cases of
choriocarcinoma with brain metastases. The first one was manifested by
neurological deterioration as the first sign of metastasis, while the second
patient had firstly metrorrhagia and in the further couse neurological
disturbances that suggested the presence of brain tumor. In both cases we
applied a combined treatment of surgery, chemotherapy and radiation therapy.
Both patient survived with high quality of life. Conclusion. A successful
outcome of brain metastases of choriocarcinoma was obtained by the use of a
combined treatment of surgery, chemotherapy and radiation therapy. In cases
of young women with brain metastases, gynecological malignancy should be
always considered.

Published: October 2013

Introduction. Special entities like solitary bone plasmocytoma (SBP) or
extramedullary plasmacytoma (EMP) can be found in a less than 5% of patients
with plasma cell disorders. EMP of the tongue represents very rare
localization of the head and neck plasmacytoma. Case report. We report a
case of 78-years-old woman who developed EMP of the tongue base detected by
the magnetic resonance imaging (MRI) of the head and neck region.
Immunohistochemical profile of the tumor tissue biopsy (CD38, IgG, kappa
positivity) indicated diagnosis of EMP. The diagnosis was established with
additional staging which confirmed the absence of other manifestation of the
disease. The patient was treated with 40 Gy of radiotherapy in 20 doses
resulting in the achievement of the complete remission of the disease. This
case was discussed with the reference to the literature. Conclusion. EMP of
the tongue base is a very rare entity of plasma cell dyscrasias. Appropriate
irradiation results in the achievement of a long-term remission and a
potential cure of the disease.
Glargine insulin for treatment of naturally occurring diabetes mellitus in dogs
Authors: Hess Rebecka S. , Drobatz Kenneth J.
Published: October 2013

Objective—To evaluate the effects of twice-daily glargine insulin administration in dogs with diabetes mellitus.

Design—Open-label, prospective clinical trial.

Animals—10 dogs with naturally occurring diabetes mellitus.

Procedures—Dogs with poorly regulated or newly diagnosed diabetes mellitus were enrolled if their owners agreed to return them to the hospital at 1- to 3-week intervals for 4 follow-up visits. During each follow-up visit, blood glucose concentrations were measured every 2 hours for at least 10 hours after feeding a diet high in insoluble fiber and after administration of glargine insulin (time 0). The initial glargine insulin dosage was 0.5 U/kg (0.23 U/lb) SC twice daily.

Results—All dogs had well-regulated diabetes mellitus at a mean ± SD of 38 ± 14 days (median, 43 days; range, 7 to 55 days) following study enrollment. At the time diabetes mellitus was well regulated, mean glargine insulin dosage was 0.5 ± 0.15 U/kg (0.23 ± 0.068 U/lb; median, 0.5 U/kg; range, 0.32 to 0.67 U/kg [0.15 to 0.30 U/lb]) twice daily, and 3 dogs were receiving a dosage < 0.4 U/kg (0.18 U/lb). In dogs with well-regulated diabetes mellitus, the mean minimum blood glucose concentration (163 ± 89 mg/dL; 95% confidence interval, 100 to 227 mg/dL) was detected 2 hours after administration of glargine insulin and the mean maximum blood glucose concentration (230 ± 95 mg/dL; 95% confidence interval, 64 to 323 mg/dL) was detected 12 hours after administration of glargine insulin. There was no significant difference between mean minimum and mean maximum blood glucose concentrations nor were there significant differences between blood glucose concentrations measured at other time points. Blood glucose concentration < 80 mg/dL was measured at least once in 7 of 10 dogs.

Conclusions and Clinical Relevance—Results of the present study suggested that, in diabetic dogs fed a diet high in insoluble fiber, glargine insulin is a peakless insulin that does not induce a distinct blood glucose concentration nadir. For glargine insulin, 0.3 U/kg (0.136 U/lb) SC twice daily is recommended as an initial dosage.
Superficial digital flexor tendonitis in cutting horses: 19 cases (2007–2011)
Authors: Tipton Tyler E. , Ray Chris S. , Hand D. Reese
Published: October 2013

Objective—To characterize superficial digital flexor (SDF) tendon lesions in the forelimbs of cutting horses and determine recurrence rate and prognosis for this condition.

Design—Retrospective case series.

Animals—19 cutting horses with SDF tendonitis.

Procedures—Medical records for horses evaluated for SDF tendonitis in 2007 through 2011 were reviewed. Data regarding age, sex, lameness grade, affected limb, and treatment were collected. Ultrasonographic images were reviewed, and lesion characteristics were recorded. Follow-up telephone interviews with owners or trainers were conducted to determine recurrence of SDF tendonitis, return of horse to its previous level of activity, and duration of the convalescent period.

Results—All 19 horses initially evaluated for SDF tendonitis had similar lesions in the lateral aspect of the tendon. The right forelimb was affected in 11 horses, and the left forelimb was affected in 7 horses; 1 horse was affected in both forelimbs. Mean lameness grade was 1.26 (range, 0 to 3). Of 17 horses for which follow-up information was available, 3 had recurrence of tendon lesions and 1 developed a lesion in the contralateral forelimb SDF tendon; 16 horses returned to their previous level of activity.

Conclusions and Clinical Relevance—The location of SDF tendonitis in cutting horses appeared to be unique in that no central core lesions were detected ultrasonographically. Lesions at the periphery of the tendon may have an increased ability to heal, compared with lesions at the central core. Results suggested that cutting horses with SDF tendonitis have a better prognosis than that reported for affected racehorses.
Effects of body position and extension of the neck and extremities on lung volume measured via computed tomography in red-eared slider turtles (Trachemys scripta elegans)
Authors: Mans Christoph , Drees Randi , Sladky Kurt K. , Hatt Jean-Michel , Kircher Patrick R.
Published: October 2013

Objective—To determine the effects of body position and extension of the neck and extremities on CT measurements of ventilated lung volume in red-eared slider turtles (Trachemys scripta elegans).

Design—Prospective crossover-design study.

Animals—14 adult red-eared slider turtles.

Procedures—CT was performed on turtles in horizontal ventral recumbent and vertical left lateral recumbent, right lateral recumbent, and caudal recumbent body positions. In sedated turtles, evaluations were performed in horizontal ventral recumbent body position with and without extension of the neck and extremities. Lung volumes were estimated from helical CT images with commercial software. Effects of body position, extremity and neck extension, sedation, body weight, and sex on lung volume were analyzed.

Results—Mean ± SD volume of dependent lung tissue was significantly decreased in vertical left lateral (18.97 ± 14.65 mL), right lateral (24.59 ± 19.16 mL), and caudal (9.23 ± 12.13 mL) recumbent positions, compared with the same region for turtles in horizontal ventral recumbency (48.52 ± 20.08 mL, 50.66 ± 18.08 mL, and 31.95 ± 15.69 mL, respectively). Total lung volume did not differ among positions because of compensatory increases in nondependent lung tissue. Extension of the extremities and neck significantly increased total lung volume (127.94 ± 35.53 mL), compared with that in turtles with the head, neck, and extremities withdrawn into the shell (103.24 ± 40.13 mL).

Conclusions and Clinical Relevance—Vertical positioning of red-eared sliders significantly affected lung volumes and could potentially affect interpretation of radiographs obtained in these positions. Extension of the extremities and neck resulted in the greatest total lung volume.
On the multi-index (3m-parametric) Mittag-Leffler functions, fractional calculus relations and series convergence
Authors: Paneva-Konovska Jordanka
Published: October 2013

In this paper we consider a family of 3m-indices generalizations of the classical Mittag-Leffler function, called multi-index (3m-parametric) Mittag-Leffler functions. We survey the basic properties of these entire functions, find their order and type, and new representations by means of Mellin-Barnes type contour integrals, Wright pΨq-functions and Fox H-functions, asymptotic estimates. Formulas for integer and fractional order integration and differentiations are found, and these are extended also for the operators of the generalized fractional calculus (multiple Erdélyi-Kober operators). Some interesting particular cases of the multi-index Mittag-Leffler functions are discussed. The convergence of series of such type functions in the complex plane is considered, and analogues of the Cauchy-Hadamard, Abel, Tauber and Littlewood theorems are provided.
Upper ankle ligament rupture and long term problems in a patient with Ehlers Danlos Syndrome — a case report
Authors: Horst Klemens , Dienstknecht Thomas , Pishnamaz Miguel , Kobbe Philipp , Sellei Richard , Pape Hans
Published: October 2013

Rupture of the upper ankle joint ligaments is a common injury. Therapy in patients with Ehlers Danlos Syndrome (EDS) is a challenge due to the autosomal-dominant collagenopathy. Therapeutic recommendations and long term results in treatment of patients with EDS are rare. Therefore uncertainty exists. We present a case of clinical and radiologic long term results after ligament rupture of the upper ankle joint in a patient with EDS. A literature review tries to reveal current therapeutic strategies in patients with EDS.
Visible light photoelectrocatalytic degradation of rhodamine B using a dye-sensitised TiO2 electrode
Authors: Wahyuningsih Sayekti , Purnawan Candra , Kartikasari Puspa , Praistia Novita
Published: October 2013

Titanium dioxide is a promising catalyst for application in the photodegradation of organic pollutants in water due to its powerful oxidising property and long-term photostability. This study presents the production of titanium dioxide using the sol-gel process, dye sensitisation of the TiO2 electrode, and the performance of that cell. Sensitisation of titanium dioxide was performed using a dye, i.e., Fe(II)-polypyridyl complexes. The photoelectrocatalytic degradation of rhodamine B (RB) using ITO/TiO2/dye as electrode was investigated via a series of potentials, from +1.0 V to −1.0 V, and at various pH and NaCl concentration values (ITO is indium tin oxide conductive glass). The photoelectrocatalytic degradation of RB was performed with a visible light lamp. The change in the absorbance of RB with various potentials indicated that the absorbance of RB in solution systems with the sensitised TiO2 electrodes decreased with increasing anodic potential bias. The degradation cell exhibited better performance when the positive anodic bias was applied. The pH values of RB in solution systems also influence the photoelectrodegradation process because of the different RB species present. NaCl concentration also affects the activity of RB photoelectrocatalytic degradation due to changes in the ionic strength character of the electrolyte.

Authors: Filipiak-Szok Anna , Kurzawa Marzanna , Szłyk Edward
Published: October 2013

The antioxidant activity (AA), total phenolic content (TPC) and total flavonoids content (TFC) in Dong quai (DQ, Angelica sinensis) raw materials and dietary supplements (DS) containing this plant were determined using the CUPRAC, FRAP and fluorescence methods. The antioxidant activity for DQ aqueous extracts revealed by CUPRAC was (1330.45 ± 1.30) μmol Trolox equivalent (TE) per 100 g of dry mass (DM), whereas the antioxidant activity as determined by FRAP was (1813.9 ± 2.0) μmol of TE per 100 g of DM. Lower values were noted for the fluorescence method than for CUPRAC and FRAP (ranging from (35.96 ± 0.3) to (304.6 ± 1.4) μmol of TE per 100 g of DM). The highest TPC values were determined for an aqueous extract of DQ ((3330.3 ± 2.3) μmol of TE per 100 g of DM), while TFC for ethanolic extracts of DQ was ((146.50 ± 0.5) mg of quercetin equivalent (QE) per 100 g of DM). Cinnamic acid, isomers of benzoic acid and derivatives of quercetin were analysed by HPLC-PDA. The ferulic acid concentration in an ethanolic extract of DQ was (21.83 ± 0.07) mg per 100 g of DM. Of the flavonols detected, rutin exhibited the highest concentration in ethanolic extract of DQ ((3.32 ± 0.13) mg of QE per 100 g of DM). Other phytochemicals (alkaloids, saponins, flavonoids, anthraquinones, tannins, steroids, etc.) were identified by phytoscreening colour reaction. The results were analysed by principal component analysis (PCA), cluster analysis and one-way ANOVA tests.

Authors: Shah Krunal , Parikh Jigisha , Dholakiya Bharat , Maheria Kalpana
Published: October 2013

Conversion of high free fatty acids (FFA) containing acid oil (AO) to fatty acid methyl esters (FAME) using silica sulfuric acid (SSA) as a solid acid catalyst was investigated. Process parameters such as reaction temperature, reaction time, catalyst loading, and methanol to oil molar ratio were optimized using the Taguchi orthogonal array method. Maximum FFA conversion (97.16 %) was achieved under the optimal set of parameter values viz. 70°C, 4 mass % catalyst loading, and 1: 15 oil to methanol molar ratio after 90 min. SSA was reused three times successfully without a significant loss in activity. Biodiesel produced from AO met the international biodiesel standards. Determination of kinetic parameters proved that the experimental results fit the pseudo first order kinetic law.

Authors: Scheele Jantine , Vijfvinkel Frank , Rigter Marijn , Swinkels Ilse C.S. , Bierman-Zeinstra Sita M.A. , Koes Bart W. , Luijsterburg Pim A.J.
Published: October 2013

Background

In the Netherlands, direct access to physical therapy was introduced in 2006. Although many patients with back pain visit physical therapists through direct access, the frequency and characteristics of episodes of care are unknown.

Objective

The purposes of this study were: (1) to investigate the prevalence of direct access to physical therapy for patients with low back pain in the Netherlands from 2006 to 2009, (2) to examine associations between mode of access (direct versus referral) and patient characteristics, and (3) to describe the severity of the back complaints at the beginning and end of treatment for direct access and referral-based physical therapy.

Design

A cross-sectional study was conducted using registration data of physical therapists obtained from a longitudinal study.

Method

Data were used from the National Information Service for Allied Health Care, a registration network of Dutch physical therapists. Mode of access (direct or referral) was registered for each episode of physical therapy care due to back pain from 2006 to 2009. Logistic regression analysis was used to explore associations between mode of access and patient/clinical characteristics.

Results

The percentage of episodes of care for which patients with back pain directly accessed a physical therapist increased from 28.9% in 2006 to 52.1% in 2009. Characteristics associated with direct access were: middle or higher education level (odds ratio [OR]=1.3 and 2.0, respectively), previous physical therapy care (OR=1.7), recurrent back pain (OR=1.7), duration of back pain <7 days (OR=4.2), and age >55 years (OR=0.6).

Limitations

The study could not compare outcomes of physical therapy care by mode of access because this information was not registered from the beginning of data collection and, therefore, was missing for too many cases.

Conclusions

Direct access was used for an increasing percentage of episodes of physical therapy care in the years 2006 to 2009. Patient/clinical characteristics associated with the mode of access were education level, recurrent back pain, previous physical therapy sessions, and age.
The Groningen Meander Walking Test: A Dynamic Walking Test for Older Adults With Dementia
Authors: Bossers Willem J.R. , van der Woude Lucas H.V. , Boersma Froukje , Scherder Erik J.A. , van Heuvelen Marieke J.G.
Published: October 2013

Background

Current dynamic walking tests, used in studies with older adults with dementia, rely strongly on healthy cognitive and physical function. Therefore, the Groningen Meander Walking Test (GMWT) was developed specifically for people with dementia. The aim of the GMWT is to measure dynamic walking ability by walking over a meandering curved line, with an emphasis on walking speed and stepping accuracy, while changing direction.

Objective

The purpose of this study was to investigate the feasibility, test-retest reliability, and minimal detectable change (MDC) of the GMWT.

Design

A repeated-measures design was used.

Methods

Forty-two people with dementia participated in the study. Adherence rate, adverse events, repetition of instructions during test performance, test duration, and number of oversteps were assessed.

Results

The adherence rate was excellent, with no adverse events. No repetitive instructions were given during test performance, and test duration was short (mean=17.16 seconds) with few oversteps (mean=1.94 oversteps). Test-retest reliability for participants without a walking device was excellent for the GMWT time score (intraclass correlation coefficient [ICC]=.942), with an MDC of 2.96 seconds. Test-retest reliability for participants with a 4-wheeled walker (4WW) was moderate (ICC=.837), with an MDC of 10.35 seconds. For the overstep score, a marginal ICC of .630 was found, with an MDC of 4.38 oversteps.

Limitations

No fall data were available, and there was a volunteer bias.

Conclusions

The GMWT is a feasible test for people with dementia. With the GMWT time score, a reliable and sensitive field test to measure walking abilities in older adults with dementia is available. The GMWT overstep score can be used to give information about the execution according to protocol and should be emphasized during the instructions. Future studies need to investigate the validity of the GMWT.
Spinal intradural cystic venous angioma originating from a nerve root in the cauda equina
Authors: Nishimura Yusuke , Hara Masahito , Natsume Atsushi , Nakajima Yasuhiro , Fukuyama Ryuichi , Wakabayashi Toshihiko , Ginsberg Howard J.
Published: October 2013

A spinal intradural extramedullary venous angioma is extremely rare and has not been previously reported. In this paper, the authors report on this entity with morphological and immunohistochemical evidence, and discuss the surgical strategy for its treatment. A 54-year-old woman presented to Nagoya University Hospital complaining of left-sided pain in the hip, thigh, and inguinal and perianal regions, with progressive worsening during the previous 2 weeks. Lumbar spine MRI showed an intradural extramedullary cyst at the level of T12–L1, which extended from the conus medullaris to the cauda equina. The cyst wall was not enhanced on T1-weighted MRI with Gd. Intraoperatively, a midline dural opening allowed the authors to easily visualize a dark-reddish cyst behind the spinal nerve rootlets in the cauda equina adjacent to the conus medullaris. The cyst was believed to originate from one of the spinal nerve rootlets in the cauda equina and a cluster of veins was identified on the cyst wall. The cyst was resected with the affected nerve rootlet. The surgery left no detectable neurological deficit. Based on the morphological and immunohistochemical evidence, the lesion was diagnosed as a venous angioma. No tumor recurrence was confirmed based on MRI at the time of the 2-year follow up. This is the first report of an intradural extramedullary cystic venous angioma that was successfully resected.

The authors undertook this study to document the clinical outcomes of microendoscopic laminotomy, a minimally invasive decompressive surgical technique using spinal endoscopy for lumbar decompression, in patients with lumbar spinal stenosis (LSS).

Methods

A total of 366 patients were enrolled in the study and underwent microendoscopic laminotomy between 2007 and 2010. Indications for surgery were single- or double-level LSS, persistent neurological symptoms, and failure of conservative treatment. Microendoscopy provided wide visualization through oblique lenses and allowed bilateral decompression via a unilateral approach, through partial resection of the base of the spinous process, thereby preserving the supraspinous and interspinous ligaments and contralateral musculature. Clinical symptoms and signs of low-back pain were evaluated prior to and following surgical intervention by applying the Japanese Orthopaedic Association (JOA) scoring system, Roland-Morris Disability Questionnaire (RMDQ), Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ), and 36-Item Short Form Health Survey (SF-36). These items were evaluated preoperatively and 2 years postoperatively.

Results

Effective circumferential decompression was achieved in all patients. The 2-year follow-up evaluation was completed for 310 patients (148 men and 162 women; mean age 68.7 years). The average recovery rate based on the JOA score was 61.3%. The overall results were excellent in 34.9% of the patients, good in 34.9%, fair in 21.7%, and poor in 8.5%. The mean RMDQ score significantly improved from 11.3 to 4.8 (p < 0.001). In all categories of both JOABPEQ and SF-36, scores at 2 years' follow-up were significantly higher than those obtained before surgery (p < 0.001). Twelve surgery-related complications were identified: dural tear (6 cases [1.9%]), wrong-level operation (1 [0.3%]), transient neuralgia (4 [1.3%]), and infection (1 [0.3%]). All patients recovered, and there were no serious postoperative complications.

Conclusions

Microendoscopic laminotomy is a safe and very effective minimally invasive surgical technique for the treatment of degenerative LSS.

Increasing evidence exists that treatment of complex medical conditions in high-volume centers is found to improve outcome. Patients with subarachnoid hemorrhage (SAH), a complex disease, probably also benefit from treatment at a high-volume center. The authors aimed to determine, based on published literature, whether a higher hospital caseload is associated with improved outcomes of patients undergoing treatment after aneurysmal subarachnoid hemorrhage.

Methods

The authors identified studies from MEDLINE, Embase, and the Cochrane Library up to September 28, 2012, that evaluated outcome in high-volume versus low-volume centers in patients with SAH who were treated by either clipping or endovascular coiling. No language restrictions were set. The compared outcome measure was in-hospital mortality. Mortality in studies was pooled in a random effects meta-analysis. Study quality was reported according to the GRADE (Grading of Recommendations Assessment, Development and Evaluation) criteria.

Results

Four articles were included in this analysis, representing 36,600 patients. The quality of studies was graded low in 3 and very low in 1. Meta-analysis using a random effects model showed a decrease in hospital mortality (OR 0.77 [95% CI 0.60–0.97]; p = 0.00; I2 = 91%) in high-volume hospitals treating SAH patients. Sensitivity analysis revealed the relative weight of the 1 low-quality study. Removal of the study with very low quality increased the effect size of the meta-analysis to an OR of 0.68 (95% CI 0.56–0.84; p = 0.00; I2 = 86%). The definition of hospital volume differed among studies. Cutoffs and dichotomizations were used as well as division in quartiles. In 1 study, low volume was defined as 9 or fewer patients yearly, whereas in another it was defined as fewer than 30 patients yearly. Similarly, 1 study defined high volume as more than 20 patients annually, and another defined it as more than 50 patients a year. For comparability between studies, recalculation was done with dichotomized data if available. Cross et al., 2003 (low volume ≤ 18, high volume ≥ 19) and Johnston, 2000 (low volume ≤ 31, high volume ≥ 32) provided core data for recalculation. The overall results of this analysis revealed an OR of 0.85 (95% CI 0.72–0.99; p = 0.00; I2 = 87%).

Conclusions

Despite the shortcomings of this study, the mortality rate was lower in hospitals with a larger caseload. Limitations of the meta-analysis are the not uniform cutoff values and uncertainty about case mix.
Les élites indiennes du Mexique central face à la Conquête espagnole
Authors: Dehouve Danièle
Published: October 2013

Es un tópico de los especialistas en cuestiones del México indígena la afirmación de que los españoles decapitaron el imperio azteca y se encontraron frente a un pueblo de campesinos dotado solamente de sus prácticas agrícolas y de sus ritos agrarios. De hecho, la historia del México indígena es ante todo la de sus élites que, durante cuatro siglos, conocen una agonía interminable. Los recientes hallazgos sobre el carácter sagrado de la monarquía azteca echan una luz nueva sobre las tentativas de adaptación de los "reyes" (tlatoque) a las estructuras impuestas por los españoles. Esas estructuras, que marcaron la historia indígena del siglo XVI, tomaran esencialmente dos formas : la lucha de los "reyes" por que les reconocieran el estatuto de caciques, y su inserción en los "gobiernos" de los pueblos.

L'aventure ambiguë de la vanguardia nicaraguayenne : la méprise des élites
Authors: Pailler Claire
Published: October 2013

Dans le Nicaragua où la guérilla de Sandino s'opposait à l'occupation des marines US, entre 1928 et 1933, se développpe un mouvement de contestation et de rénovation à la fois littéraire et politique : le Movimiento de Vanguardia. Force indéniable de créativité et ferment d'une prise de conscience identitaire pour toute une grande génération d'écrivains, il montre aussi, par sa fascination pour une solution dictatoriale, que la générosité et la puissance créatrice ne prédisposent pas nécessairement à la lucidité de l'analyse politique.

Granada de Nicaragua : port mythique du Détroit Incertain
Authors: Pailler Claire
Published: October 2013

RESUMEN: Fundada en 1524, Granada siguió siendo, a pesar de muchos avatares, el puerto lacustre con acceso al Atlántico que anhelaba ser "el" puerto de Centroamérica. Después de ser incendiada por los filibusteros en 1856, la ciudad recobró cierta actividad antes de caer, desde principios del siglo XX, en una modorra provincial. Pero el mito y la literatura se han apoderado de la memoria de su esplendor, magnificándola.
"N'allez pas à Buenos Aires...". Émigration et Terre promise dans la littérature populaire en catalan (1889)
Authors: Gilard Jacques
Published: October 2013

RÉSUMÉ : Débat sur Buenos Aires, le grand port d'Amérique du Sud et le but de l'émigration économique, tel qu'il se manifeste dans les feuilles volantes catalanes de 1889. A côté du motif biblique de la Terre promise, d'autres éléments issus des Écritures interviennent dans le débat et expriment l'aversion populaire pour l'exil. Si quelque chose de l'expérience de l'émigration figure réellement dans ces feuilles, c'est surtout le désarroi des premiers jours vécus en Argentine que l'on peut y reconnaître.
Development of microsatellite markers in Cratylia mollis and their transferability to C. argentea (Fabaceae)
Authors: López‐Roberts M. Cristina , de Queiroz Luciano Paganucci , van den Berg Cássio
Published: October 2013

• Premise of the study: This work aimed to develop microsatellite markers for Cratylia mollis as tools to assess its genetic diversity and structure and to evaluate their potential cross‐amplification in related species.

• Methods and Results: Microsatellite markers were developed using a microsatellite‐enriched library and an intersimple sequence repeat library. From a set of 19 markers, 12 microsatellite loci were polymorphic and presented considerable variation in allele number (2–11), expected heterozygosity (0.226–0.883), and polymorphism information content per locus (0.212–0.870). Cross‐amplification in C. argentea was successful in 16 loci, 12 of which were polymorphic (2–10 alleles).

• Conclusions: The polymorphism of this set of microsatellite markers for C. mollis, as well as their successful cross‐amplification in C. intermedia and C. bahiensis and their transferability to C. argentea, supports their use in future comparative studies to understand the mechanism involved in population divergence and speciation in the genus.
Soup Kitchen . L'encadrement philanthropique à l'épreuve des budgets ouvriers (Londres, 1875-1906)
Authors: Lhuissier Anne
Published: October 2013

L’offre de repas charitables –  dinner tables et soup kitchens  – qui se développe à Londres dans le dernier quart du XIX e siècle entrave l’encadrement pratique des activités charitables et l’encadrement moral des classes populaires, que les agents du monde philanthropique s’évertuent à mettre en place. Elle représente tout ce contre quoi ils se battent : le secours à domicile ( outdoor relief ) en espèces ou en nature et la charité indiscriminée ( indiscriminate charity ) favorisaient la dépendance des pauvres et les affranchissaient de la rationalité économique indispensable à la gestion du budget domestique. La confrontation des pratiques et des représentations des philanthropes aux budgets et aux pratiques ouvrières montre également que ces formes de distribution sont assez peu compatibles avec les habitudes populaires. Pourtant celles-ci déplacent les frontières des catégories en usage au sein du monde philanthropique, sur lesquelles se maintenait un modus vivendi et mettent en évidence la place ambiguë du marché de consommation comme intermédiaire dans les relations entre philanthropie et classes populaires.
La barrière ne fera pas le niveau
Authors: Bodin Romuald , Orange Sophie
Published: October 2013

Les cartographies de l’enseignement supérieur sont généralement fondées sur une série d’oppositions duales, séparant cycle court et cycle long, filières académiques et filières professionnalisantes, ou encore secteur « sélectif » et secteur « non sélectif ». Or, cette partition est non seulement erronée, mais elle est au principe d’affirmations sur l’état actuel de l’enseignement supérieur qui le sont tout autant. Parmi ces dernières, la question de la sélection à l’entrée à l’université resurgit chroniquement. C’est en vue d’apporter notre contribution à ce débat que nous proposons ici de revenir sur la fausse dichotomie de l’enseignement supérieur entre filières sélectives et filières ouvertes, et de remettre en question quelques fausses associations comme sélectif = élitiste, sélectif = électif, ou encore abandon = échec.
« Souffrir non souffrir » : la mélancolie d'Oblomov
Authors: Laufer Laurie
Published: October 2013

La figure littéraire d’Oblomov, roman éponyme de Gontcharov, entrant en écho avec Un homme qui dort de Georges Perec, déploie les rythmes de la mélancolie. Oblomov est un homme qui dort. La mélancolie d’Oblomov abrase tout rythme et tout circuit pulsionnel. Ne pas être atteint, ne rien ressentir, tel est le mode d’être d’Oblomov. Éviter d’être affecté par le monde qui l’entoure ou qui le traverse. Qu’est-ce que désirer ne pas être ? Éviter tout excès lié au sexuel ? Éviter toute dépense de soi, toute brûlure pulsionnelle ? Oblomov enchaîné fait corps avec lui-même. Il est le corps mélancolique.
Un regard pénétrant (Histoire de l'Homme aux loups)
Authors: Pélabon Caroline
Published: October 2013

Les écrits sur (et de) l’Homme aux loups jalonnent toute sa vie, depuis sa névrose infantile analysée par Freud et sa psychose adulte par Ruth Mack Brunswick, jusqu’à ses propres Mémoires et le récit par Muriel Gardiner de la seconde partie de sa vie. Son fantasme fondamental, tel qu’il apparaît dans le rêve des loups, détermine le déroulement de ce parcours en même temps qu’il s’y révèle. À travers ce fantasme se dévoile l’homosexualité féminine primaire, s’originant dans le lien maternel préœdipien, qui est à la source de la structure paranoïaque de Sergueï Pankejeff.
The Populist Phenomenon
Authors: Urbinati Nadia
Published: October 2013

Le phénomène populiste Cet article propose un compte-rendu analytique du populisme. Il soutient que les composants qui en font un phénomène identifiable sont une simplification et une polarisation des divisions politiques afin de renforcer l’unification des masses contre les élites existantes, suivant un fil narratif incarné la plupart du temps par un leader. Le populisme est, par conséquent, à la fois interne à la démocratie représentative et un défi à celle-ci ; il rivalise avec elle sur le terrain de la signification et de la mise en pratique de la représentation puisqu’il vise à une identification plus authentique entre représentés et représentants. Après un préambule sur la distinction entre le mouvement populaire et le populisme, cet article défend l’idée que, pour mieux comprendre ce phénomène, il est nécessaire de le replacer au sein de la tradition romaine et républicaine.
Opportunistic Detection Methods for Emotion-Aware Smartphone Applications
Authors: Bisio Igor , Delfino Alessandro , Lavagetto Fabio , Marchese Mario
Published: October 2013

Human-machine interaction is performed by devices such as the keyboard, the touch-screen, or speech-to-text applications. For example, a speech-to-text application is software that allows the device to translate the spoken words into text. These tools translate explicit messages but ignore implicit messages, such as the emotional status of the speaker, filtering out a portion of information available in the interaction process. This chapter focuses on emotion detection. An emotion-aware device can also interact more personally with its owner and react appropriately according to the user’s mood, making the user-machine interaction less stressful. The chapter gives the guidelines for building emotion-aware smartphone applications in an opportunistic way (i.e., without the user’s collaboration). In general, smartphone applications might be employed in different contexts; therefore, the to-be-detected emotions might be different.
A Recovery Algorithm of Star Energy Distribution for Star Sensor under High Dynamic Condition
Authors: Wang Cun Lian , Li Bao Hua , Wang Chang Hong , Chen Yun
Published: October 2013

Under the condition of high dynamic, there is a pixel shift phenomenon which is called smear in the star image sampled by star sensor. The recovery algorithm of star energy distributing for star sensor is presented in the paper. The quaternion of next frame is calculated with the previous continuous quaternion. All the ideal star coordinates of star image in the FOV is calculated with the quaternion of next frame. Then the angle between the two previous continuous axis directions is calculated with the previous continuous axis directions calculated with the previous continuous quaternion. The radius of threshold scan window of star image is calculated according to the angle. Finally, within the star image radius of the threshold scan window, shift the original star image to make the shifted star energy distribution continuous. So the star image distribution subjects to 2-D Gaussian distribution, and the star coordinates is obtain with centroiding algorithm. A star sensor featuring a recovery algorithm of star energy distributing for star sensors proposed in this paper was for demonstration at night sky experiment.
The Effects of SiO2/PEG Suspension on Mechanical Properties of Rigid Polyurethane Foams
Authors: Feng Xin Ya , Li Shu Kui , Wang Yan , Wang Ying Chun , Liu Jin Xu
Published: October 2013

In order to improve the mechanical properties of the polyurethane foams, the silica nanoparticles were added into the foams in the form of SiO2/PEG suspension during the preparation process. The microstructure, density, static mechanical properties and dynamic mechanical properties of the foams were investigated. Microstructure analysis shows that the silica nanoparticles were uniformly dispersed in the foams, however when the amounts of SiO2/PEG suspension is more than 2.5 wt.%, cracks in the skelecton were observed in foams. With the increased SiO2/PEG suspension, the density, static compression strength and dynamic compression strength show an increasing tendency. When the SiO2/PEG suspension is 2.5 wt.%, the density of the foams increased 4.17 %, while the static compression strength increased 26 %. When the SiO2/PEG suspension is 10 wt.%, the density of the foams increased 16 %, while the dynamic compression strength increased 60.5 %. The corresponding mechanism was discussed in the paper.

Published: October 2013

Bioleaching is the solubilization of metals from ores by microorganisms. This process is more efficient than conventional methods in the metal recovery from low grade ores while decreasing the operating cost and the environmental impact. Among the bioleaching bacteria, the Gram-negative chemolithoautotrophic acidophilic Acidithiobacillus ferrooxidans has the ability to adhere to mineral surface and to form biofilm. The genes involved in the production of this biofilm are controlled by a cellular communication system called Quorum Sensing (QS). The QS occurs mainly through the production of acyl homoserine lactones (AHLs). A functional QS system has been identified in At. ferrooxidans with an acyl synthase (AfeI) and a transcriptional regulator (AfeR). Here, our purpose is to characterize the quorum sensing regulon and particularly the genes involved in biofilm formation in At. ferrooxidans. This has been done by cell adhesion experiments comparing At. ferrooxidans grown with or without Tetrazol, an AHL analogue that activates the cell adhesion to mineral surface. The second step has been to compare the expression of some genes predicted to be involved in the QS regulon in At. ferrooxidans grown in the presence/absence of Tetrazol using real-time PCR. These two different strategies are expected to give insight on the moment at which the At. ferrooxidans QS regulon is switched on. The formation of biofilm could improve the bioleaching operation and therefore the understanding of the QS regulon is of primordial importance.
