Background: The bone remodeling after tooth extraction can result in the loss of as much as 50% of the buccal wall and a global crestal reduction in width of 3.87mm according to a recent systematic review. Multiple surgical protocols using biomaterials are proposed in order to limit the typical postextraction bone resorption. However, because of the heterogeneity of the studies and, more specifically, of the assessment methods, it is difficult to assert the superiority of one technique over another. Aim: The objective of this study was to develop a new radiographic method to assess alveolar bone remodeling after socket preservation procedures. Methods: Sixteen extraction sites (in 14 patients) localized in the upper anterior maxilla were treated with bovine hydroxyapatite (0.25–1mm particles) and a saddled connective tissue graft. A radiographic 3-dimensional assessment of the hard tissues was performed at baseline and at 3 months after the procedure. Standardized horizontal measurements were taken at three corono apical levels ( 2, 5, and 9mm) and at three mesio-diatal level (Mesial, Center, and Distal) in the buccal and palatal aspects. Vertical measurements were also recorded in nine regions over the top of the alveolar crest. Results: Extraction socket-preservation technique assessed in the present study significantly reduced horizontal bone remodeling. The horizontal dimension of the crest decreased by 1.6mm (20%) in the cervical regions ( 2mm level), experienced a moderate decrease of 1mm (12%) at the 5mm level, and experienced a very low decrease of 0.5mm(6%) in the apical ( 8mm) level. The losses were always significantly higher in the buccal than in the palatal aspect. Buccally, the maximal bone remodeling at the cervical level remained below 1mm. Vertical bone resorption was homogeneous and was < 1mm in the nine measured regions. Conclusions and clinical implications: The radiographic measuring methodology proved to be accurate and reproducible. It can be applied in other clinical settings. Moreover, the surgical procedure evaluated in the present study, significantly limits the postextraction buccal bone remodeling compared with the data found in the literature for untreated extraction socket in the aesthetic area. However, a complete inhibition of the bone remodeling was not reached and the authors suggest a surgical technique using a ‘‘saddled’’ connective tissue graft to thicken buccal soft tissue biotype and consequently compensate for cervical bone loss.

We are concerned with a problem in which a firm or franchise enters a market by locating new facilities where there are existing facilities belonging to a competitor. The firm aims at finding the location and attractiveness of each facility to be opened so as to maximize its profit. The competitor, on the other hand, can react by adjusting the attractiveness of its existing facilities with the objective of maximizing its own profit. The demand is assumed to be aggregated at certain points in the plane and the facilities of the firm can be located at predetermined candidate sites. We employ Huff's gravity-based rule in modeling the behavior of the customers where the fraction of customers at a demand point that visit a certain facility is proportional to the facility attractiveness and inversely proportional to the distance between the facility site and demand point. We formulate a bilevel mixed-integer nonlinear programming model where the firm entering the market is the leader and the competitor is the follower. In order to find the optimal solution of this model, we convert it into an equivalent one-level mixed-integer nonlinear program so that it can be solved by global optimization methods. Apart from reporting computational results obtained on a set of randomly generated instances, we also compute the benefit the leader firm derives from anticipating the competitor's reaction of adjusting the attractiveness levels of its facilities. The results on the test instances indicate that the benefit is 58.33% on the average. [less ▲]

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 ▲]

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 ▲]

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.

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).

While the influence of the grinding media alloy composition on the flotation performances of sulphide ores has been widely studied, its role in the flotation of mixed (oxide and sulphide) ores is poorly documented. For some deposits, the mixed ores zone is well developed and can be of great importance for the economics of a mining project. These ore types often present technical challenges for their beneficiation such as sulphides tarnishment, slimes generation, presence of hydrophobic gangue or presence of acid consuming gangue. This study highlights the importance of matching the right grinding media alloy to the mineralogy of the ore, particularly its degree of weathering and to the subsequent flotation scheme. Shifting the grinding media towards less electrochemically active alloys significantly enhanced the grade-recovery curves and the flotation kinetics of the sulphides fraction, particularly when high degrees of sulphides oxidation were induced within the orebody or during stockpiling. For ores with high acid consuming gangue and medium acid soluble copper content that require a preconcentration of the oxide fraction by flotation through activation by sulphidisation, the higher sulphides flotation rates achieved with the use of high chromium alloys limited the amount of sulphides entering the sulphidisation stages and led to a better selectivity between acid insoluble and acid soluble copper allowing better downstream extractive metallurgy performances.

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.
