Because of the PK-Weir geometric specificities, its hydraulic capacity remains difficult to predict without using experimental techniques. A 1D numerical model of the flow over a PK-Weir has been developed at the Research unit HACH at the University of Liege. It is based on a 1D modeling of the inlet and the outlet separately, with a single upstream reservoir and interactions between both flows by exchange of mass and momentum along the lateral crest. The comparison of the numerical results with various experimental data showed the ability of the numerical model to predict with reasonable accuracy the release capacity of a PK-Weir, whatever its geometry. The tests of the solver enable to highlight the significant influence of the inlet and outlet width on the weir release capacity. They also suggest that improvements of the numerical model may lie in the evaluation of the discharge coefficient of the lateral crest. [less ▲]

Coordinating abilities of 4R-1,2,4-triazole derivatives (R = glycine ethyl ester (L1), glycine (L2), diethylamino malonate (L3), methionine (L4) and diethyl aminomethylphosphonate (L5)) towards ZnII ions have been studied in solution, in solid state and versus three zinc-b-lactamases. The crystal structure of [Zn3(L4)6(H2O)6] (6) is described; it is the first crystal structure involving a 1,2,4-triazole functionalized methionine. It forms a trinuclear complex with central zinc octahedrally coordinated by only L4, whereas terminal zinc ions coordination sphere is completed by three water molecules. L4 exhibits a dual functionality of a bridging bidentate ligand as well as an anion. A dense hydrogen bonding network connects these trinuclear entity into a 3D supramolecular network. The ZnII ions in 6 are held at equidistance (3.848 Å) which coincidently matches with the corresponding Zn Zn distance in the binuclear zinc enzyme from Bacillus cereus (3.848 and 4.365 Å). Among L1–L5 screened for b-lactamase assay, L4 shows modest inhibition for BcII enzyme. [less ▲]

Since concrete has been used for more than a century, many structures need repair in different degrees and others need strengthening to withstand higher loads. Moreover, the number of new concrete structures is constantly increasing, and therefore repair or retrofitting requirements increase. Present concerns of sustainable development emphasizing repair or strengthening instead of new construction, acts as incentive to this trend. The bonded overlay technique is particularly suitable in the case of structures with large areas like industrial floors. This paper has the ambition to present reliable design methodology for the practitioner. Surface preparation, overlay design and material selection, application process and QC/QA are discussed and guidelines are proposed in order to enhance quality of repair operations. [less ▲]

Antigen expression and purification are laborious, time consuming and frequently difficult steps in the process of antibody production. In the present study, we developed a method avoiding these two steps. This method relies on the injection of histocompatible living cells stably expressing the antigen as a cell surface type II transmembrane fusion protein. A vector, nicknamed pCD1-CD134L, was constructed to express the antigen fused at the carboxyterminal end of the human CD134 ligand (CD134L) type II transmembrane protein on the surface of eucaryotic cells. This vector was shown to induce cell surface expression of epitopes from human c-Myc (soluble protein), uterogloblin-related protein 1 (secreted protein) and CD94 (type II transmembrane protein). Using this vector, we developed a method to produce antibodies without antigen production. The flowchart of this method is as follows: (i) cloning of the antigen in the pCD1-CD134L vector; (ii) production of a histocompatible cell line stably expressing the CD134L-antigen fusion protein; (iii) testing for cell surface expression of the fusion protein by targeting the CD134L carrier; and (iv) prime-boost immunisation with living cells expressing the fusion protein. This method was successfully used for production of polyclonal antibodies raised against Ixodes ricinus calreticulin (secreted protein) in mice and for production of monoclonal antibodies raised against an epitope of Vaccinia virus A56 (type I transmembrane protein) protein in rat. The present study is the first to demonstrate the use of a type II transmembrane protein as a carrier for cell surface display of antigens. [less ▲]

In Belgium, the culture of Nordmann fir (Abies nordmanniana) is mainly located in Wallonia region. The planted area is estimated in average at 5000 ha  that annualy produce some 4 million Christmas trees destined in priority to the export market. In vitro propagation by somatic embryogenesis is considered as an alternative method to seedlings for producing homogeneous and orthotropic trees on a large scale. Currently, the performances of the somatic embryo (SE) maturation is still insufficient to consider any commercial application of the technology. In this way , the effect of three substances  (2,3,5-triiodobenzoïque acid  as TIBA, 2 - (p-chlorophenoxy)-2-methylpropionic acids as PCIB, p-hydroxbenzoïque as PHBA)  reported as ''anti-auxins'' have been tested with three embryogenic lines on the formation and maturation of normal somatic embryos.

Jean-Jacques Rousseau est né avec la conscience de son altérité : fils d’horloger, citoyen de Genève, il se sent dès son plus jeune âge différent du monde qui l’entoure. Par sa « réforme » au début des années 1750, il transformera officiellement cette altérité en faire-valoir. Pourtant, quand résonne le glas de la condamnation de ses œuvres (Émile et le Contrat social) en 1762, l’homme jusque-là différent, se sent étranger, incompris, seul contre tous, comme en témoigne sa correspondance. Cet article se donne pour objectif d’étudier ce sentiment d’altérité et d’étrangeté à travers la correspondance personnelle de Jean-Jacques Rousseau de 1762 à 1765 (soit de la condamnation de l’Émile et du Contrat social jusqu'au départ pour l’Angleterre chez David Hume).

La crise financière mondiale qui a éclaté en 2008 et les effets désastreux qu’elle a occasionnés sur le secteur minier en RDC (qui avait été placé au centre des politiques de croissance et de lutte contre la pauvreté) posent avec encore plus d’acuité la question de la diversification de la structure économique dans une province comme le Katanga. Au problème de la vulnérabilité d’un tel modèle de croissance s’ajoute le constat qui est fait dans cette étude du manque d’effet d’entrainement de l’activité des grands groupes miniers sur le reste de l’économie locale, en termes de développement des capacités productives et de création d’emplois.

Thirty-eight endurance horses underwent clinical and ancillary examinations, including haematological and biochemical evaluation, standardised exercise tests both on a treadmill and in the field, Doppler echocardiography, impulse oscillometry, video endoscopy and collection of respiratory fluids. All of the examined poorly performing horses were affected by subclinical diseases, and most of them had multiple concomitant disorders. On the contrary, the well-performing horses were free of any subclinical disease. The most frequently diagnosed diseases were respiratory disorders, followed by musculoskeletal and cardiac problems. Poor performers exhibited lower speeds at blood lactate concentration of 4 mmol/l (VLA4) and at heart rates of 160 (V160) and 200 bpm (V200) on the treadmill and in the field, as well as slower recovery of heart rate.

The aim of the study was to investigate the effect of hyaluronic acid (HA) intra articular injections (IA) on osteoarthritis (OA) biomarkers in patients with knee OA. Prospective open label study. Fifty-one patients with unilateral symptomatic K-OA received IA injections of 2mL of HA on days (D) 1, 7, 14 and were followed 3 months. At D-15 patients were examined and X-rays performed, to exclude patients with bilateral K-OA, or those with more than three symptomatic OA joints. From 15 days (D-15) before the first injection to D90 concomitant therapies were unchanged. Walking pain (WP) on VAS was obtained at each visit. Urine (U) and serum (S) samples were obtained at D-15, D1, D30, and D90. S-C2C, S-Cartilage oligomeric matrix protein, S-HA, S-CS 846 epitope, S-type II collagen propeptide, and U-type II collagen C telopeptide (U-CTX II/creatinin) were assayed. Predictive factors of response were analyzed using logistic regression. Correlations between variables were obtained using Spearman test. Forty-five patients were analyzed. Between D-15 and D1 there was no difference for any biomarkers At D1, WP (SD) was correlated with U-CTX II/creat (p = 0.006). Between D1 and D90: U-CTX II/creat decreased significantly. After adjustment for confounding variables there was a significant correlation between clinical response and U-CTX II/creat variation. U-CTX II and S-HA at baseline were independently predictive of clinical response. This study showed that 90 days after HA IA injections, U-CTX II levels significantly decrease compared to baseline, suggesting a slowdown of type II collagen degradation.

The efficacy of grafting materials for alveolar bone regeneration procedures has been repeatedly corroborated by clinical and scientific evidence. Although an ever growing number of biomaterials are available on the market, the origins, material characteristics, bioactivity and osteoconductive properties of these products are not always known by clinicians, hence often hampering an adequate product selection. The purpose of this contribution was to provide an overview of five different types of osteoconductive grafting materials frequently used in dentistry (Bio-Oss®, Cerasorb M™, Bone Ceramic®, Natix®, Genos®) and to summarize their physico-chemical and morphological characteristics at the macro- and micro-scale. Furthermore, the influence of these properties on the in vivo behaviour of these biomaterials is discussed. The results of this study are presented as data sheets, which may prove helpful for clinicians in the design of their treatment strategies. [less ▲]
