Objectives: The technical nature of laparoscopy, and the required specific laparoscopic tools and medical skills, may render this approach difficult in developing countries. We hypothesized that laparoscopy may be developed in the Cliniques Universitaires de Kinshasa (CUK), and may be cost-effective. The final aim of this program is to bring the benefits of laparoscopy to the DRC population, by allowance of adequate training on the UNIKIN personnel, including anaesthetists, surgeons and nurses, who in the future will have to locally form the DRC medical and nursery students. Methods: With the financial support from Wallonie-Bruxelles International (WBI), a complete CUK team, including a surgeon (2 years training in Belgium), an anaesthetist and nurses, were trained in Belgium and then afterwards in DRC. The laparoscopic equipment was sent to Kinshasa, and three theoretical and practical missions of Belgian teams were organised. Results: Over a 2 year period, 116 laparoscopic procedure were performed, including 32 appendectomies, 41 cholecystectomies, 11 hernia repairs, 9 laparoscopy explorations for peritoneal carcinoma assessment and biopsy, 8 procedures for catheter of dialysis peritoneal, 5 gynecologics procedures, and 10 other miscellaneous procedures. Conclusions: A joined approach, taking into account on one hand the training of the skills locally trained to adapt itself to some difficulties, on the other hand institutions of scientific support and a real program and local will of development of this new procedure are the wages of development, accessibility and durability of such news approach in developing countries. All University and non-University team willing to join such a project are welcome. [less ▲]

Objectives: The aim of this study was to determine results of kidney transplantation (KT) from controlled donation after cardio-circulatory death (DCD). Primary end-points were graft and patient survival, and post-transplant complications. The influence of delayed graft function (DGF) on graft survival and DGF risk factors were analyzed as secondary end-points. Methods: This is a retrospective mono-center review of a consecutive series of 80 DCD-KT performed at the University Hospital of Sart Tilman, University of Liège, between Jan 2005 and Dec 2011. Mean patient follow-up was 28.5 months. Results: Overall graft survival was 93.7%, 89.5%, 85% and 81.3% at 3 months, 1 year, 3 and 5 years, respectively. Death-censored graft survival at the corresponding time points was 93.7%, 93.7%, 90.8% and 90.8%. Main cause of graft loss was patient’s death with a functioning graft. No primary non-function grafts were encountered. Renal graft function was suboptimal at hospital discharge, but nearly normalized at 3 months. DGF was observed in 36% of all DCD-KT. DGF significantly increased post-operative length of hospitalization, but had no deleterious impact on graft function or survival. Donor body mass index (BMI) ≥30 kg/m2, recipient BMI ≥30 kg/m2 and pre-transplant dialysis duration significantly increased the risk of DGF in a multivariate logistic regression analysis (p < 0.05). Conclusions: Despite a higher rate of DGF, controlled DCD-KT offers a valuable contribution to the pool of deceased donor kidney grafts, with comparable mid-term results to those procured after brain death.

Objectives: Adhesion formation is common after abdominal surgery. The incidence and severity of adhesion formation following open or laparoscopic surgery remain controversial. The role of CO2 pneumoperitoneum is also largely discussed. This study aimed to compare adhesion formation following peritoneal injury by electrocoagulation performed through open or laparoscopic procedures in a rat model. Methods: Sixty male rats were randomized to undergo a 1.5cm peritoneal injury with unipolar cautery under general anesthesia: open surgery (group A, n=20), laparoscopic surgery with CO2 pneumoperitoneum (group B, n=20) and laparoscopic surgery with air pneumoperitoneum (group C, n=20). Duration of the procedures was fixed at 90 minutes in all groups, and pneumoperitoneum pressure at 10mmHg. Ten days later, the animals underwent a secondary laparotomy to score peritoneal adhesions using qualitative and quantitative parameters. Results: Forty-five rats developed at least one adhesion, respectively 95% in group A, 83% in group B and 55% in group C (P<0.01; Group C vs Group A, P<0.01). According to number, thickness, tenacity, vascularization, extent, type, and grading according to Zühkle classification, no significant difference was observed between groups A and B. The distribution of adhesions after open surgery was significantly different than after laparoscopic surgery (P<0.001). Interestingly, group C rats developed significantly less adhesions at the traumatized site, and their adhesions had less severe qualitative scores compared to open surgery (P<0.01). Conclusions: In this animal model, CO2 laparoscopic surgery did not decrease the formation of postoperative adhesion, compared to open surgery. The difference with the animals operated with air pneumoperitoneum emphasizes the role of CO2 in peritoneal injury leading to adhesion formation. [less ▲]

Objectives: Results of DCD-LT at the University Hospital of Liège were evaluated from 2003 to 2011. Methods: Medical records of 56 DCD liver recipients were retrospectively reviewed with regard to patient and graft survivals and biliary complications. Mean follow-up was 26.4 months. Mean donor age was 56.3±14.5 years (25 - 83). Donor causes of death were due to anoxia (51.8%), stroke (32.1%) and head trauma (14.3%). Mean WIT, CIT and suture time were 20.5±7.1min (10 – 39), 265.6±85.1min (105 – 576), and 40.8±7.8 min (25 – 61), respectively. 95% of liver grafts were locally shared. HTK was the most commonly used perfusion solution (86%). Mean recipient age was 56.6±10.5 years (29 – 73). Indications for LT included ESLD (53.6%) and HCC (46.6%). Mean MELD score at transplant was 15.6±6.1points (6 – 40). Results: No primary non-function grafts. Mean peak serum AST and bilirubin levels were 2520±3621UI/L and 50.2±49.2mg/L, respectively. Eight patients (14.3%) developed biliary complications. No intra-hepatic bile duct strictures or re-transplantation. Global patient and graft survival was 92.6% at 3 months, 92.6% at 1 year, 73.8% at 3 years and 60% at 5 years. Death-censored patient and graft survival at the corresponding time points was 92.6%, 92.6%, 87.7% and 87.7%. Thirteen liver grafts were lost during follow-up exclusively due to recipient deaths. The rate of HCC recurrence was 33.3%. Conclusions: Controlled DCD donors are a valuable source of transplantable liver grafts. Primary results are encouraging and apparently as good as those from brain-dead donation LT essentially due to short WIT and CIT. [less ▲]

Objectives: Postoperative peritoneal adhesions are frequent after abdominal surgery. Many preventive agents have been tried in animal models and in clinical trials, but up to now, there has been no definitive strategy to prevent their formation. In this study, the effectiveness of parecoxib (Dynastat®), a selective cyclooxygenase-2 inhibitor, in preventing experimental intra-abdominal adhesions in rats was studied. Methods: Thirty male rats who underwent a primary surgical procedure aiming at inducing peritoneal injury to produce intraabdominal adhesion, were randomized in three groups: (A) control group, no therapy; (B) intraperitoneal (IP) parecoxib group; (C) intramuscular (IM) parecoxib group. Ten days later, a xyphopubic midline incision was performed and the whole abdominal cavity was explored to score the peritoneal adhesions. Results: Twenty-three rats developed adhesions, 9 (100%) in group A, 7 (70%) in group B and 4 (40%) in group C (P=0.01). The extent and severity scores of adhesion were significantly lower in groups B and C than those in control group (p<0.001). Type of adhesions was measured at 2.25 ± 0.67 in group A, 1.20 ± 0.86 in group B and 0.82 ± 0.80 in group C. This was significantly different between group A and B (p<0.001), between A and C (p<0.001). But no significant difference was found between group B and C (p=0.17). Conclusions: In this study, we found a significant effect on parecoxib in the prevention of postoperative adhesions. But, without avoiding completely the formation of adhesion, parecoxib reduces significantly extent and severity of postoperative adhesions in rats treated with IP or IM parecoxib administration.

Objectives: Targeted therapies of liver metastases are gaining a major stake in current and future treatment options. However, the malignant lesions are heterogeneous in nature offering niches for cancer cells causing treatment resistance and relapse. Therefore, a rational strategy is needed to select targetable antigens that would overcome this intra-tumoral heterogeneity. Methods: After ethical committee approval, 48 fresh liver metastases of colorectal origin were prospectively collected from patients undergoing liver resection. Here we macroscopically divided the lesion in different zones and generated a unique quantitative picture of the proteome heterogeneity in colorectal carcinoma liver metastases. Particular focus was laid on accessible proteins, a protein subclass comprising cell membrane associated and extracellular proteins. Accordingly, the tissues were ex-vivo biotinylated, affinity purified and analyzed for each zone separately using nano-UPLC-MSe proteomics technique. In total over 1500 unique proteins were statistically divided into different patterns of expression. Results: We have generated a quantitative picture of the proteome heterogeneity in colorectal carcinoma liver metastases. The study offers insight into novel targets but also antigens against which the antibodies are already involved in clinical trials or treatment of liver metastases. Extensive clustering and validation experiments highlight novel markers that offer the potential to homogeneously cover the metastatic lesion and become better targets. Conclusions: Two such antigens, LTBP2 and TGFBI were selected for functional analysis in colorectal carcinoma cells. In vitro and in vivo experiments showed that in particular TGFBI is relevant for migration and proliferation capacity of colorectal cancer cells. The suppression of this protein led to significant inhibition of tumor growth, crystalizing it as bona fide target for the development of anti-metastases therapies. [less ▲]

Objectives: This study aims to evaluate the feasibility of performing an anatomy scanned for fetal abnormalities at the time of nuchal translucency (NT) measurement in Vietnamese population Material and methods: In a prospective study, 2500 singleton pregnancies measured fetal NT and scanned structural anatomy in the first trimester; then checked fetal morphology systematically at 18-24 weeks and followed up to their delivery. According to ultrasonographic abnormalities and amniocentesis, we evaluated the detection rate of ultrasound for aneuploidy in the first and second trimester of gestation. Results: The sensitivity and specificity of ultrasound for aneuploidy was 17.2% and 99.7%, respectively. All 13 cases of fetal ultrasonographic anomalies related significantly with an increased NT (≥ 2.4mm) (p < 0.001). 30.8% of these abnormalities that included cystic hygroma, omphalocele and holoprosencephaly were detected at 11-13.6 weeks’ gestation. In the second trimester scanning, 69.2% of major structural anomalies found and the detection rate of central nervous system malformation, abnormal heart, abdominal wall defect, face anomaly and skeletal deformities were 85.7%, 100%, 66.7%, 50% and 75%, alternatively. Conclusion: Scanning of fetal anatomy at the time of NT measuring is useful to detect fetal abnormalities, especially aneuploidy in Vietnamese pregnancies. [less ▲]

Objectives: The aim of this study is to find the risk factors of fetal chromosomal aberrations in order to classify a high risk pregnancy in our prenatal care unit. Material and methods: A prospective study was carried out during one year in our clinic. 523 cases of amniocentesis was followed up and evaluated the relation with abnormal result (fetal aneuploidies) and the risk factors such as advanced maternal age (≥ 35 years old), parity, habitation, positive triple test (≥ 1/250), fetal malformation history and abnormal signs in the first and second trimester scanning. Results: The incidence of fetal aneuploidy was 3.4% (18/523 [95%CI: 2.1-5.4%]) and the trisomy 21 showed the most common in these chromosomal aberrations (67%). The younger women (< 35 years old), nulliparous, positive triple test and abnormal ultrasonographic findings (included increased nuchal translucency [≥ 2.4mm], absent nasal bone in the first trimester scanning and/or echogenic nodule in ventricular) was identified as the risk factors of fetal aneuploidies (OR was 2.3 [95%CI: 0.8-6.7], 4.0 [95%CI: 1.4-13.2], 3.3 [95%CI: 0.3-33.5] and 9.4 [95%CI: 1.1-79.2], respectively). The abnormal ultrasonographic findings found a relation significantly with abnormal chromosomes (p=0.04). Conclusion: Abnormal ultrasonographic findings in the first and second trimester were the important markers for predicting fetal aneuploidy, especially trisomy 21. [less ▲]

Purpose: Synovitis is a key factor in osteoarthritis (OA) pathophysiology, contributing to both patient symptoms and disease progression. In this study, using an original methodology comparing normal/reactive (N/R) and inflammatory (I) synovial membranes zones, we investigated the gene expression profiles of synovial cells from these areas and identified differentially regulated pathways. Methods: Synovial cells (SC) were isolated from OA synovial specimens obtained from 12 patients undergoing knee replacement. The inflammatory status of the synovial membrane was characterized by the surgeon according to macroscopic criteria including the synovial vascularization, the villi formation and the hypertrophic aspect of the tissue. At the surgery time, the synovial membrane was dissected and biopsies from N/R and I areas cultured separately for a period of 7 days. Total RNA was extracted using the RNeasy Mini Kit. RNA purity and quality were evaluated using the Experion RNA StdSens Analysis kit (Bio-rad Laboratories). Gene expression profiling between N/R and I areas was performed using Illumina’s multi-sample format Human HT-12 BeadChip (Illumina Inc.). Differential analysis was performed with the BRB array tools software. Class Comparison test between N/R and I areas was based on paired t-test where N/R and I were paired for each patient. The biological relevance of up- and down-regulated genes was analyses with Ingenuity Pathways Analysis (Ingenuity® Systems). Western blot was performed to confirm certain intermediate expression. Results: From among 47000 probes, 17500 were filtered out. Probes with a p-value below than 0.005 were chosen and classified as up- or down-regulated ones. By this way, 896 differentially expressed genes between N/R and I zones were identified. Among these, 576 genes were upregulated (I/NR > 1.5) and 320 downregulated (I/NR < 0.75). With Ingenuity Pathways Analysis, a significant number of the top ranking differentially expressed genes were identified as inflammatory, Wnt and angiogenic pathways. Interleukin (IL)-6 and -8, chemokines (CXCL1, CXCL2, CXCL5, CXCL6, CXCL16) and arachidonate 5-lipoxygenase (ALOX5) were identified as the most upregulated in I zones in the inflammatory pathway. Interestingly, the alarmin S100A9 was found strongly upregulated in this pathway. Wnt5A and LRP (Low density lipoprotein receptor-related protein) 5 were upregulated whereas FZD (Frizzled homolog) 2 and DKK (dickkopf homolog) 3 were downregulated in the Wnt signaling pathway. Finally, stanniocalcin (STC)-1, an intermediate in angiogenesis was identified as the most upregulated gene in I zones compared to N/R zones. This difference of expression was confirmed at the protein level. Conclusions: Using a unique culture system, this study is the first to identify different expression pattern between two areas of synovial membrane from the same OA patient. These differences concern several key pathways involved in OA pathogenesis, i.e. inflammation, Wnt and angiogenesis. This analysis also provided interesting information regarding new potent intermediates as S100A9 and STC-1. They could be potential targets for chondroitin sulfate, one of the most used molecules in the management of OA. New experiments are being perfomed at the moment to elucidate the potential effect of this molecule on these specific differentially expressed genes in the same culture system. [less ▲]

Acetic acid bacteria encounter various harsh conditions during acetic acid fermentation. Ethanol as the main substrate and acetic acid as the major product at low pH can influence deeply on the cellular functions of acetic acid bacteria. In previous studies in CWBI, Acetobacter senegalensis was used for production of dried vinegar starters; however the impact of stressors (ethanol and acetic acid) on A. senegalensis remained unclear. In this study, different techniques such as flow cytometry, culturability on solid medium and 2-DiGE were used comparatively to investigate the effect of carbon sources of inoculum media on the tolerance of A. senegalensis to stressors. Analysis of respiration system by flow cytometric methods showed that the presence of 2% (v/v) acetic acid in inoculum medium, in one hand, causes 80% of cells to continue to do respiration after a sudden exposure to 1- 3% (v/v) acetic acid in stress media while 89.7% of cells grown in glucose appeared as dead cells after an abrupt exposure to 3%(v/v) of acetic acid. On the other hand, 59.2% and 49.33% of cells grown in the presence of 2% (v/v) of acetic acid could maintain their entire membrane integrity after exposure to 1% and 3% (v/v) of acetic acid, respectively. Inoculum medium contained 5% (v/v) of ethanol as a carbon source enabled about 90% of cells to keep their growing capacities after a sudden exposure to 3% acetic acid. In contrast, just 40% of cells grown in glucose as a carbon source maintained their culturability on solid medium after exposure to 1% acetic acid. A similar profile of culturability was observed for the cells grown in 5% (v/v) ethanol or 2% (v/v) of acetic acid. A proteomic approach (2-DiGE) was used to analyze proteins expressed in the presence of different carbon sources. Differentially expressed proteins were mainly associated with energy metabolism, carbohydrate metabolisms, folding, sorting and degradation processes. The relative abundance of proteins was extensively different for cell grown in glucose compared with protein contents of cells grown in ethanol or acetic acid. In conclusion, production of a cost effective vinegar starter needs a qualified biomass which tolerates ethanol and acetic acid. Tolerance of A. senegalensis to acetic acid depends to a great extent on the composition of the medium which cells grow in. In spite of low adaption to acetic acid for cell grown in glucose, using ethanol or acetic acid in inoculum media renders a physiological state in A. senegelensis which enables it to cope with higher concentration of acetic acid readily, this biomass has a potential to be used as a starter [less ▲]

Im Rahmen des AMICE-Projektes wurde eine erste zusammenhängende internationale Modellrechnung für den gesamten Flusslauf der Maas inklusive des Nebenflusses Rur durchgeführt. Dazu wurden die in den Anrainerstaaten Frankreich, Belgien, Deutschland und der Niederlande vorgehaltenen numerischen Modelle verwendet. Die Randbedingungen dieser Modelle wurden in einem iterativen Prozess abgeglichen. Die Ergebnisse der zusammenhängenden Simulation tragen zunächst zu einem besseren Systemverständnis bei. Im weiteren Verlauf des Projektes fließen sie in eine Risikobetrachtung ein und werden zur Bewertung von Maßnahmen zur Reduzierung des Hochwasserrisikos vor dem Hintergrund zu erwartender Änderung der Bemessungsgrößen infolge einer erwarteten Klimaänderung herangezogen.

We report on high-resolution spectropolarimetric observations of the hot subdwarf stars HD 76431 and Feige 66, using the ESPaDOnS echelle spectropolarimeter at CFHT. We compute cross-correlation Stokes I and V line profiles to enhance the signal-to-noise ratio. We then average all available cross-correlation profiles of each star to further decrease the noise level. Although both targets were previously reported to host kilo-gauss magnetic fields, we do not derive any evidence of large-scale photospheric fields from our sets of observations, in spite of tight error bars on the longitudinal field of the order of 60 gauss for HD 76431 and 200 gauss for Feige 66. A new analysis of FORS1 observations of HD 76431, which provided the basis for the original claim of field detection, confirms the absence of any detectable Zeeman signature, with an error bar of about 100 gauss on the longitudinal magnetic field.

Organ dysfunction determines the severity of sepsis and is correlated to mortality. Endothelial increased permeability contributes to the development of organ failure. AMP-activated protein kinase (AMPK) has been shown to modulate cytoskeleton and could mediate endothelial permeability. Our hypothesis is that AMPK controls sepsis-induced hyperpermeability in the heart and is involved in septic cardiomyopathy. Sepsis was induced by intraperitoneal injection of liposaccharide, 10 mg/kg (LPS). Alpha-1 AMPK knockout mice (α1KO) were compared with wild-type. Vascular permeability was characterized by Evans blue extravasation. Inflammatory cytokine mRNA expression was determined by qPCR analysis. Left ventricular mass was assessed by echocardiography. In addition, to emphasize the beneficial role of AMPK on heart vascular permeability, AMPK activator (acadesine) was administered to C57Bl6 mice before LPS injection. The ANOVA test with Bonferroni's post hoc test and the log-rank test were used. P < 0.05 was considered as significant. Increased cardiac vascular permeability was observed in the LPS group in comparison to untreated animals (2.5% vs. 16%; P < 0.05). The α1KO mice exhibited an increase vascular permeability after LPS injection in comparison to wild-type mice (41.5% vs. 16%; P < 0.05). α1KO animals had a significant mortality increase after LPS injection (70% vs. 10%; P < 0.05). LPS markedly induced the production of proinflammatory cytokines (TNFα, IL-1β, IL-6) that were significantly higher in the α1KO animals. More importantly, LPS treatment leads to an increased left ventricular mass in the α1KO mice within 24 hours, suggesting the onset of edema. Finally LPS-induced vascular hyperpermeability was greatly reduced after AMPK activation by acadesine (13.2% vs. 40%; P < 0.05). AMPK importantly regulates cardiac vascular permeability and could control the sepsis-induced cardiomyopathy. AMPK could represent a new pharmacological target of sepsis. [less ▲]

The genetic parameters of CH4 indicators were estimated by single trait test-day models from 16,825 records collected on Walloon Dual Purpose Belgium Blue cows in their first 3 lactations. Fatty acid based CH4 indicators published in the literature were predicted from milk mid-infrared spectra using 597 calibration samples. For the indicator showing the highest link (R2 =0.88) with SF6 CH4 data, the average daily heritability was 0.21, 0.20 and 0.10 for each lactation, respectively. The sire genetic variability was on average 2.82 kg2 of CH4 per lactation. The genetic difference between the sires having cows eructing higher and lower CH4 was 10 kg of CH4 averaged per lactation. In conclusion, CH4 indicators can be predicted by MIR and the genetic variability of these traits seems to exist. [less ▲]

Introduction : Le diabète atteint environ 3% de la population française. Or, cette maladie expose à l'apparition précoce de complications cardiovasculaires. Les troponines de nouvelles générations hautement sensibles pourraient être un bon outil diagnostic pour mettre en évidence des macroou micro-angiopathies non diagnostiquée chez ces patients. Le but de notre étude était de comparer la performance de la troponine T ultrasensible (hsTnT) (Roche Diagnostic) avec la troponine I ultrasensible (TnI II) (Abbott Diagnostic) chez le sujet diabétique. Matériel et méthodes : Vingt patients diabétiques (âge moyen : 52.6 ± 8.4 ans) ont été sélectionnés sur le critère d’un taux d’hémoglobine glyquée (HbA1c) élevé. Ces sujets ont été comparés à vingt sujets contrôles d’âge moyen : 60.05 ± 2.86 ans. Les patients atteints d’insuffisance rénale et d’affections cardiovasculaires ont été exclus. Les analyses ont été réalisées sur du plasma hépariné lithium. La hsTnT a été dosée par électrochemiluminescence sur le Modular E (Roche Diagnostic). Abbott utilise des microparticules chemiluminescentes pour le dosage de la TnI II sur l’ARCHITECT i. Résultats : Les sujets diabétiques ont un taux plasmatique de hsTnT représenté par les valeurs suivantes [médiane (1er quartile, 3ème quartile)] : 0,007 (0,03 ; 0,018) ng/mL ; alors que les sujets contrôles négatifs présentent les valeurs suivantes : 0,003 (0,003 ; 0,004) ng/mL. La différence de taux de hsTnT observée entre ces 2 populations est statistiquement significative (p = 0,000922). Pour la TnI II, on observe un taux plasmatique de: 0,004 (0,003 ; 0,075) ng/mL chez les sujets diabétiques et 0,002 (0,001 ; 0,005) ng/mL chez les sujets contrôles. La différence de taux de TnI II observée entre ces 2 populations n’est pas statistiquement significative (p > 0,005). Discussion-conclusion : Au décours d’un diabète, il apparait que les taux de hsTnT sont augmentés de façon significative par rapport au groupe des contrôles négatifs. Si les taux hsTnT augmentent chez le diabétique, il semblerait normal qu’il en soit de même pour la TnI II, vu que ces deux marqueurs sont intimement liés. Nous ne l’avons pas observé mais ceci peut être du à la plus faible performance analytique du dosage de la TnI II utilisé. Cette libération de hsTnT dans le sang peut être due aux micro- et macro-angiopathies au niveau des coronaires induites au cours d’un diabète. [less ▲]

This paper describes recent advances in prediction software using advanced data-mining tools, and shows how this can significantly increase the operational value of the data gathered. These new tools allow for new operational procedures to be defined that increase the usages of the network without decreasing security of supply. We will use the example of dynamic line rating, i.e. determining the thermal rating of an overhead line based on real-time environmental parameters (temperature, wind speed & direction and solar radiation) to highlight how the use of numerical data-mining tools can help us reliably predict future behavior of power networks.

Substrate limitation responsive biosensors have been used in order to detect spatial substrate heterogeneities, , inside industrial bioreactors (whole-cell biosensor). Three green fluorescent protein (GFP) transcriptional reporters have been chosen in E.coli, i.e. uspA::gfp, csiE::gfp and yciG::gfp. The promoter uspA is induced in response to a variety of stresses whereas the two other promoters, csiE and yciG, are supposed to be more specific in front of a substrate limitation. The responsiveness of these biosensors has been assessed in chemostat reactor. Secondly, the same biosensors have been tested in well-mixed laboratory reactors and in scale-down reactors able to reproduce industrial conditions. Finally, a mini scale-down platform has been proposed as a high throughput tool to investigate rapidly the usefulness of a given microbial biosensor. Local heterogeneities in mini-bioreactor have caused a decrease of GFP expression, as in scale-down reactor. The presence of GFP in supernatants was noticed and this leakage seems to be correlated with the membrane permeability. [less ▲]

Nowadays, tillage simplification is an increasing practice. Many advantages are cited in the literature, such as energy saving, soil conservation etc. Agricultural management practices influence soil structure, but consequent changes in soil hydrodynamic behaviour at the field scale are still not well understood. Many studies focus only on macroscopic measurements which do not provide mechanistic explanations. Moreover, research shows divergent conclusions over structure modification. The aim of this work is to fill this gap by quantifying soil structure modification depending on tillage intensity through both macroscopic and microscopic measurements, the latter improving our comprehension of the fundamental mechanisms involved.

Comet 8P/Tuttle was the target of an ESO multiwavelength observing campaign in 2008. Observations of the spatial distribution of C2 and C3 were obtained, as well as simultaneous direct detections of the C2 parent species C2H2 and C2H6. We combine these observations to investigate the origin of cometary C2. The observed C2 column densities are inconsistent with a production of C2 from C2H2, C2H6, and C3. Based on a photochemical model, we quantitatively discuss the influence of further potential C2 parent species. The assumption of C4H2 as an additional C2 parent species in comet 8P/Tuttle provides the best explanation for the observed C2 column densities. [less ▲]

The saddle gall midge, Haplodiplosis marginata (von Roser), has been detected in Belgium since 2010, after several decades without any reporting. It had indeed caused serious damages between 1965 and 1970. This insect is a European cereal pest whose larvae feed on stems and engender saddle-shaped depressions, resulting in yield losses. Face with the resurgence of this pest, it was decided to study its spatial distribution and, because serious damages were observed in some regions, to develop effective curative control. To date, chemical protection seems to be the only immediate solution in case of heavy emergences. Experimentation was conducted in a highly infested field (Meetkerke, Belgian Polders), according to a randomized complete blocks arrangement with four replications. Foremost, a lambdacyhalothrin-based insecticide was used to evaluate efficiency of several protection schemes, ranging between one and four spray(s). The large spread of flights observed during the 2011 spring allowed to highlight the effect of treatment date on the attack intensity and also on the galls distribution along the stem, on the different internodes: the lower internodes were protected by the early sprayings, while last sprayings induced reduction of galls number on the upper internodes. Moreover, several insecticides already registrated in cereals against aphids were compared for their efficacy against saddle gall midge. Studied pyrethroids have shown a very good efficacy, ranging between 75 % and 87 %, when applied twice with a 2 weeks interval. To be efficient, insecticide applications must thus be synchronized with the flights and egg-laying periods. Monitoring the phenology of flights is thus essential as part of integrated pest management against saddle gall midge. [less ▲]

Despite the great uncertainties regarding the future climatic context, lots of studies have focused on hydrological effects of climate change on the Meuse catchment. It appears that both winter high flows and summer low flows could be exacerbated. Climate change and its impacts on hydrology will thus affect various socio-economic sectors. High flows have been widely studied compared to low-flows. This poster will put the emphasis on a methodology developed in order to study impacts of droughts on agriculture. Agriculture is among the most impacted sectors due to climate change. The consequences could be both positive as negative in accordance with the range of predicted changes and the adaptation capacity of agricultural systems. Most of the existing studies related to climate change on agriculture focused on specific territory. Within the AMICE Interreg IVB project, a transnational approach has been developed to assess droughts impacts on agriculture through the Meuse basin. The project’s previous works gave us a common scenario of climate trends and of the evolution of the hydrology in the Meuse basin. The methodology is based on the use of a physically-based model able to simulate the water-soil-plant continuum (derived from EPIC model). In order to be transferable from one country to another, the methodology proposed used data available at the basin scale. The UE soil data base was complemented with local information on agricultural practices and statistics. Three crops have been studied: maize, wheat and barley. The basic cultural calendar is supposed to be the same for the different countries. The methodology developed permits to study the evolution of yields, leaf area index, crops stress due to excess or lack of water through time under different scenarios build up in the frame of the project. It appears that corn is negatively affected by climate change, and thus despite the CO2 fertilization effect. Wheat and barley have similar behavior and are positively affected by climate change and CO2 fertilization. Leaf Area Index study reveals that the different crops start earlier and reach earlier maturity. These first results will be completed with other economic sectors’analysis like drinkable water production, electricity production and navigation. Therefore, the project will progress towards a better understanding of economic effects of future droughts and low-flows. [less ▲]

In this paper, we present a thorough physical-chemical analysis of an engineered PCM stack, where the integration of C-doping and the use of a Ti top layer allow obtaining an Amorphous As-Deposited (A-AD) phase stable against Back End-Of-Line (BEOL) thermal budget. This PCM stack is then integrated in devices, which are extensively tested in order to validate a novel pre-coding technique compliant to the Pb-free soldering reflow issue. Finally, an original design to optimize the distribution dispersion is presented. © 2012 IEEE. [less ▲]

Par rapport à d'autres productions culturelles ou scientifiques, la particularité des médias de masse est qu'ils font quelque chose au peuple en faisant quelque chose du peuple, c'est-à-dire en le représentant à lui-même. La construction mass-médiatique du "peuple" a donc une dimension pragmatique que les études de réception doivent intégrer. C'est à quoi s'attache cette communication, notamment à travers la notion d'adresse, issue du travail de J. Derrida, et celle de "partage du sensible" formalisée par Jacques Rancière. [less ▲]

Cement blending with mineral admixtures, especially with byproduct or waste product powder, can effectively reduce consumption of cement and promote the ecology. Recently, an innovative concept was proposed to replace of “coarse” cement grains by the inert fillers for sustainable cement in the low w/c concrete cement. As a basic mechanism, particle packing plays an important role in such replacement or blending. In the first part of study, the paper discusses the particle packing aspect of cement grains, limestone filler (LF) and LF blended cement. The new developed wet packing method and a dry packing method are proposed for the evaluation purpose. The paper presents results of packing tests with the influences of PSD, cement type, vibration, mixing, blending proportions, etc. The advantages and limitations of two packing methods are also discussed in this paper.

The verbal overshadowing effect (VO) (eg, Schooler and Engstler-Schooler, 1990 Cognitive Psychology 22(1) 36–71) suggests that the fact of generating a verbal description of a previously seen face may impair subsequent performance on a lineup identification task in adults. Previous research has examined whether descriptions also impaired children’s identification abilities but no evidence of VO was found (Memon and Rose, 2002 Psychology, Crime and Law 8(3), 229–242). However, the method might not have been appropriate to observe this effect as, for instance, a 24-hour delay between the description and the identification tasks (associated with a release of the VO effect in adults) was used. Hence, in this current experiment, groups of children (7–8, 10–11, 13–14 years old) and adults were presented with a short video and then assigned to a description or a no description condition before the identification task. Participants were also assigned either to a “no delay”, a “24-hour post encoding delay” or a “24-hour post description delay” condition to determine the influence of delay on the VO effect. Results indicated that, compared to the control condition, the description decreased correct identification performance in both children and adults and no release of VO was found with delay.

The determination of isotopic ratios in comets is of primary importance for a good understanding of their origin and the formation of solar system. The [SUP]14[/SUP]N/[SUP]15[/SUP]N ratio is an interesting tracer, because of its variability among various solar system bodies. So far it has only been measured in bright comets through optical observations of the CN radical (Arpigny et al., 2003; Manfroid et al., 2009) and millimeter observations of HCN (Bockelée-Morvan et al., 2005, 2008). The measurements give for both species the same non-terrestrial isotopic composition ([SUP]14[/SUP]N/[SUP]15[/SUP]N≈150 in comets versus 272 in the Earth atmosphere), but HCN and CN are minor species. In order to get a determination of this ratio in another molecule we have searched for [SUP]15[/SUP]NH[SUB]2[/SUB] lines in a high-resolution and high signal-to-noise ratio spectrum of comet C/2002 T7 (LINEAR) obtained with the UVES spectrometer at the VLT ESO 8-m telescope (Hutsemékers et al., 2008). This work is based on a new laboratory experiment conducted with the AILES beamline spectrometer at synchrotron SOLEIL to determine the [SUP]15[/SUP]NH[SUB]2[/SUB] wavelengths by Fourier transform spectroscopy. We will present the first results obtained from these data, which have allowed to search for the first time [SUP]15[/SUP]NH[SUB]2[/SUB] emission lines in a comet.
