| 1 | Composition and antimicrobial activity of Cistus munbyi essential oil: an endemic plant from Algeria显示文摘The chemical composition and antimicrobial potential of Cistus munbyi essential oil were studied for the first time. GC and GC–MS analysis revealed 48 compounds representing 96.98% of the oil. Terpinen-4-ol(23.75%), meta-Cymene(17.30%), and Sabinene(12.38%)were the major constituents. Antimicrobial activity was evaluated against nine pathogens using the disc diffusion and broth micro-dilution methods. Results show that C.munbyi essential oil possesses strong antimicrobial activity against all strains, regardless if Gram-positive or Gramnegative bacteria, or yeast, with MICs values not exceeding10(mg/ml). In addition to its efficacy, C. munbyi essential oil has an unusual antimicrobial potency which is attributed to its specific chemical composition. Thus, findings presented here suggest that endemic C. munbyi contains a very interesting essential oil that may be valuable in several areas. | Fethi Benbelaid Abdelmounaim Khadir Mourad Bendahou Mohamed Amine Abdoune Alain Muselli Jean Costa | 2017 | Journal of Forestry Research2017，28，6： | 7 |
| 2 | Finite difference analysis of an advance core pre-reinforcement system for Toulon's south tube显示文摘The stability of shallow tunnels excavated in full face has been a major challenge to the scientific community for a long time.In recent years,new techniques based on the installation of a prereinforcement system ahead of the tunnel face were developed to control the deformations and surface settlements induced by the excavation and to ensure the sustainability of the tunnel in the long term.In this paper,a finite difference numerical simulation was conducted to study the behaviors and effects of two pre-reinforcement systems,i.e.the face bolting and the umbrella arch system installed in a section of southern Toulon tunnel in France.For this purpose,two approaches were taken and compared:a two-dimensional(2D) approach based on the convergence-confinement method,and a three-dimensional(3D) approach taking into account the complete modeling of the tunnel.A 2D numerical back-analysis was performed to identify the geomechanical parameters that offer satisfactory agreement with the measurement results.The limit of this method lies in the exact choice of the stress relaxation ratio a.To overcome this uncertainty,a 3D model was developed,which permitted to study the influence of different pre-support systems on the reaction of ground mass.Both 2D and 3D numerical approaches have been fitted to measurements recorded in a section of the Toulon tunnel and the very satisfactory correspondence has allowed validating the simulations.The results show that the 3D numerical analysis with a full discretization of the inclusions seems unquestionably the most reliable approach. | fethi kitchah sadok benmebarek | 2016 | Journal of Rock Mechanics and Geotechnical Engineering2016，8，5： | 3 |
| 3 | Association of hepatitis C virus infection and diabetes in central Tunisia显示文摘AIM:To investigate hepatitis C virus(HCV) seroprevalence in Tunisian patients with diabetes mellitus and in a control group.METHODS:A cross-sectional study was conducted to determine the HCV seroprevalence in 1269 patients with diabetes(452 male,817 female) and 1315 nondiabetic patients,attending health centers in Sousse,Tunisia.HCV screening was performed in both groups using a fourth-generation enzyme immunoassay.RESULTS:In the diabetic group,17(1.3%) were found to be HCV-infected compared with eight(0.6%) in the control group,although the difference was not significant(P=0.057).Quantitative PCR was performed in 20 patients.Eleven patients were positive and showed HCV genotype 1b in all cases.CONCLUSION:Frequency of HCV antibodies was low in patients with diabetes and in the control group in central Tunisia,with no signifi cant difference between the groups. | Naoufel Kaabia Elhem Ben Jazia Ines Slim Imen Fodha Wissem Hachfi Rafika Gaha Mabrouk Khalifa Aoutef Hadj Kilani Halim Trabelsi Ahmed Abdelaziz Fethi Bahri Amel Letaief | 2009 | World Journal of Gastroenterology2009，15，22： | 2 |

Next, we study the extremal functions fμλ , λ> 0 related to the Dunkl multiplier operators, and more precisely show that {fμλ}λ>0 converges uniformly to tSk,e(f) as λ→ 0 + . Certain examples based on Dunkl-heat and Dunkl-Poisson kernels are provided to illustrate the results. | Fethi SOLTANI | 2013 | Acta Mathematica Scientia2013，33，2： | 1 |
