Medicinski Glasnik , 2012,
Abstract: Aim To show our experience in treatment of patients with penetratingchest injuries sustained during the Homeland War in Croatia. Methods It was a retrospective study based on the records of the Department of Surgery of the University Hospital of Osijek (Croatia). All patients surgically treated during the wartime period(1991.-1995.) were analysed with respect to death rate, causes of injuries, frequency of injuries of thoracic organs and frequency of combined injuries of thorax and abdomen. Most of our patients were treated with thoracotomy as opposed to the common protocol (thoracostomy) applied in usual treatments. Results The study includes 157 patients with penetrating chest wounds, 111 (70.7%) of which were from metal fragments of bursting artillery, 37 (23.6%) of the wounded were exposed to gunshot bullets, and 9 (5.7%) had stab injuries. Lung injuries had 134 (85.4%) patients, and15 (9.6%) had injuries of the heart. Chest injuries combined with injuries of abdominal organs happened in 30 (19%) cases. The abdominal organs in question were the liver, spleen, stomach, and colon, in eight (26.6%), seven (23.3%), four (13.3%), and three (10.0%) cases, respectively. Thoracotomy was performed in 144 (91.7%) cases, 13 (8.3%) of the patients underwent thoracostomy, and 134 (85.3%) patients stayed alive. Conclusion It points out that, in our case due to organizational problems, aggressive surgical procedure of patients with penetrating chest and multiple injuries sustained in war was the good choice.

Bulletin de l'Institut Francais d'études Andines , 1999,
Abstract: UN PROJET D'ECOLE ENVIRONNEMENTALE DANS L'EXTREME NORD DU PEROU. Nous avons constaté que l actuel système d éducation forme des individus qui se reproduisent le dos tourné à l histoire régionale de la relation entre la nature et la société. Nous avons donc tenté de créer une école dans laquelle divers représentants de la société régionale, avec des chercheurs en sciences naturelles et sociales, spécialistes de l extrême nord du Pérou, tenteraient d élaborer une histoire environnementale. Cette vision partagée du passé vers l avenir permettrait, en consolidant la conscience d une identité régionale, la définition de projets de développement décentralisés qui prennent en compte les divers aspects des multiples réalités locales. Constatamos que el actual sistema de educación forma individuos que se reproducen de espaldas a la historia regional de la relación entre la naturaleza y la sociedad. Intentamos entonces crear una escuela donde diversos representantes de la sociedad regional, junto con investigadores en ciencias naturales y sociales especialistas del extremo norte del Perú, intentarían elaborar una historia ambiental. Esta visión compartida del pasado con miras al porvenir permitiría, fortaleciendo la conciencia de una identidad regional, definir proyectos de desarrollo descentralizados que tomen en cuenta los diversos aspectos de las múltiples realidades locales. A PROJECT OF ENVIRONMENTAL EDUCATION IN THE NORTHERN PERU. We show here that the current education system forms individuals that tend to ignore the historical relation at the regional level between nature and society. For that reason, we attempt to create a school where diverse representatives of the regional society in the extreme north of Peru can communicate with researchers from both the social and natural sciences who have specialized in that region, to create an environmental history of that area. This shared vision of the past with a projection towards the future would strengthen the awareness of a regional identity and allow the elaboration of projects for a decentralized development process that would take into account the great diversity of local realities.

Bulletin de l'Institut Francais d'études Andines , 1996,
Abstract: Des corrélations sédimentologiques et stratigraphiques effectuées dans trois zones de la Dépression Interandine d Equateur et de récentes datations radiométriques permettent de compléter les connaissances stratigraphiques du Tertiaire et du Quaternaire de cette partie des Andes. La dynamique sédimentaire, identique dans ces trois zones de la Dépression Interandine, est caractéristique d un bassin sédimentaire intra-arc depuis le Tertiaire supérieur. ESTRATIGRAFíA DE LOS DEPóSITOS TERCIARIOS Y CUATERNARIOS DE LA DEPRESIóN INTERANDINA DEL ECUADOR (ENTRE 0° Y 2° 15'S). Correlaciones hechas en tres zonas de la Depresión Interandina del Ecuador a partir del análisis estratigráfico, sedimentológico y dataciones radiométricas permiten complementar los datos estratigráficos conocidos y precisar la edad de los depósitos recientes. La dinámica sedimentaria, similar en las tres zonas de la Depresión Interandina es característica de una cuenca sedimentaria intra-arco desde el Terciario superior. TERTIARY AND QUATERNARY STRATIGRAPHY OF THE DEPOSITS OF THE INTERANDEAN DEPRESSION OF ECUADOR (BETWEEN 0° AND 2° 15' S). Understanding of the stratigraphy of Tertiary and Quaternary rocks of the Ecuadorian Interandean Depression is refined by stratigraphic and sedimentological correlations, as well as by radiometric age determinations. The sedimentological dynamics, similar within the three study areas of the Interandean Depression, are characteristic of an intra-arc basin since the Late Cenozoic.
Male-Male Clasping May Be Part of an Alternative Reproductive Tactic in Xenopus laevis

PLOS ONE , 2014, DOI: 10.1371/journal.pone.0097761
Abstract: Male Xenopus laevis frogs have been observed to clasp other males in a sustained, amplectant position, the purpose of which is unknown. We examined three possible hypotheses for this counter-intuitive behavior: 1) clasping males fail to discriminate the sex of the frogs they clasp; 2) male-male clasping is an aggressive or dominant behavior; or 3) that males clasp other males to gain proximity to breeding events and possibly engage in sperm competition. Our data, gathered through a series of behavioral experiments in the laboratory, refute the first two hypotheses. We found that males did not clasp indiscriminately, but showed a sex preference, with most males preferentially clasping a female, but a proportion preferentially clasping another male. Males that clasped another male when there was no female present were less likely to “win” reproductive access in a male-male-female triad, indicating that they did not establish dominance through clasping. However, those males did gain proximity to oviposition by continued male-male clasping in the presence of the female. Thus, our findings are consistent with, but cannot confirm, the third hypothesis of male-male clasping as an alternative reproductive tactic.
Secondary Instabilities of Surface Waves on Viscous Fluids in the Faraday Instability

Physics , 1995, DOI: 10.1209/0295-5075/32/4/005
Abstract: Secondary instabilities of Faraday waves show three regimes: (1) As seen previously, low-viscosity (nu) fluids destabilize first into squares. At higher driving accelerations a, squares show low-frequency modulations corresponding to the motion of phase defects, while theory predicts a stationary transverse amplitude modulation (TAM). (2) High-nu fluids destabilize first to stripes. Stripes then show an oscillatory TAM whose frequency is incommensurate with the driving frequency. At higher a, the TAM undergoes a phase instability. At still higher a, edge dislocations form and fluid droplets are ejected. (3) Intermediate-nu fluids show a complex coexistence of squares and stripes, as well as stationary and oscillatory TAM instabilities of the stripes.

Ego, Frédéric,Sébrier, Michel,Carey-Gailhardis, Evelyne,Insergueix, Delphine
Bulletin de l'Institut Francais d'études Andines , 1996,
Abstract: Les Andes Nord équatoriennes ont connu de nombreux séismes historiques destructeurs. Pour caractériser l aléa sismique de la région andine, nous avons fait une révision critique de la sismicité historique et de l ensemble des failles actives de l équateur. Les deux sources majeures de l aléa sismique sont respectivement la subduction superficielle pour la région c tière et le système transpressif des hautes Andes pour la région andine. Ce système est composé de failles décrochantes dextres d orientation N30-35°E (failles du Rio Chingual-La Sofia et Pallatanga) qui limitent respectivement au Nord et au Sud des failles inverses N-S du relais compressif de la vallée interandine (failles de Quito et de Latacunga). L étude des mécanismes au foyer superficiels des Andes équatoriennes nous a permis de calculer une vitesse de raccourcissement crustal de 4.6 mm/a selon une direction N92°E et d estimer des temps de récurrence et des périodes de retour. Un séisme de Mw = 5 pourrait se produire tous les 0.5 an, de Mw = 6 tous les 4.5 ans, de Mw = 7 tous les 45.4 ans. De même, sur une période de temps de 33 ans, 66 séismes de Mw=5 peuvent être attendus, 7 séismes de Mw=6 et 1 séisme de Mw=7. Enfin, nous avons estimé pour l ensemble des sources sismogènes de la région andine des magnitudes maximales probables et des temps de récurrence. Un séisme de magnitude 7 à 7.5 peut se produire sur la faille du Rio Chingual tous les 400±440 ans et de magnitude 6.7 à 7.2 tous les 380±320 ans sur la faille de Pallatanga. Dans la vallée interandine, la faille de Quito est susceptible d engendrer un séisme de magnitude 6.6 à 7.6 tous les 930±300 ans. LA AMENAZA SíSMICA EN LOS ANDES ECUATORIANOS. Los Andes del Norte del Ecuador son una región sismogénica mayor, donde se puede contabilizar muchos terremotos históricos destructores. A fin de determinar la amenaza sísmica sobre la región andina, se hizo la asociación sismotectónica potencial entre las fallas activas y los eventos sísmicos históricos e instrumentales. Además, para cada fuente sismogenética, se proporcionan sus parámetros geométricos y dinámicos. Los dos sistemas constituyendo la amenaza sísmica mayor son la zona de subducción superficial para la costa y el sistema mayor transpresivo dextral para la cordillera (fallas dextrales del Río Chingual-La Sofia y de Pallatanga). El estudio de los mecanismos focales superficiales de esta región nos permitió calcular una velocidad de acortamiento cortical de 4.6 mm/a según un rumbo N92°E y apreciar tiempos de recurrencia y frequencias de retorno. Un evento de Mw = 5 pudiera produci
Adherence to Hypothermia Guidelines: A French Multicenter Study of Fullterm Neonates
Marie Chevallier, Anne Ego, Christine Cans, Thierry Debillon, on behalf of the French Society of Neonatology
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0083742
Abstract: Aim The objective of this study was to describe the French practice of hypothermia treatment (HT) in full-term newborns with hypoxic-ischemic encephalopathy (HIE) and to analyze the deviations from the guidelines of the French Society of Neonatology. Materials and Methods From May 2010 to March 2012 we recorded all cases of HIE treated by HT in a French national database. The population was divided into three groups, "optimal HT" (OHT), “late HT” (LHT) and “non-indicated” HT (NIHT), according to the guidelines. Results Of the 311 newborns registered in the database and having HT, 65% were classified in the OHT group, 22% and 13% in the LHT and NIHT groups respectively. The severity of asphyxia and HIE were comparable between newborns with OHT and LHT, apart from EEG. HT was initiated at a mean time of 12 hours of life in the LHT group. An acute obstetrical event was more likely to be identified among newborns with LHT (46%), compared to OHT (34%) and NIHT (22%). There was a gradation in the rate of complications from the NIHT group (29%) to the LHT (38%) group and the OHT group (52%). Despite an insignificant difference in the rates of death or abnormal neurological examination at discharge, nearly 60% of newborns in the OHT group had an MRI showing abnormalities, compared to 44% and 49% in the LHT and NIHT groups respectively. Conclusion The conduct of the HT for HIE newborns is not consistent with French guidelines for 35% of newborns, 22% being explained by an excessive delay in the start of HT, 13% by the lack of adherence to the clinical indications. This first report illustrates the difficulties in implementing guidelines for HT and should argue for an optimization of perinatal care for HIE.

Abstract: The timing system of SPring-8 booster synchrotron generates various timing signals concerning beam injection, acceleration from 1 GeV to 8 GeV and ejection. We have improved the timing system of the synchrotron giving it better stability and flexibility. This improvement results the other merits of advanced operations, for example, storing electron beam in the synchrotron, changing the injection cycle from 1 Hz to the slower frequency to increase the RF knock-out (RF-KO) operation period and ejecting the low energy beam during ramping up.
