| 1 | 蜜瓜和西瓜果汁的射频介电特性及其与糖度的关系显示文摘为了解果汁的介电特性与其主要内部品质——糖度之间的关系,该文利用末端开路的同轴探头和阻抗分析仪测量了10 MHz~1.8 GHz的频率范围内不同成熟度的3个品种密瓜汁和4个品种西瓜汁的介电特性,同时测量了反映果汁糖度的可溶性固形物含量和果肉的含水率,分析了介电特性和糖度间的关系。结果显示:密瓜和西瓜果汁的相对介电常数和介质损耗因数皆随频率的增大单调减小,品种间的差异对介电特性有影响;1.8 GHz下密瓜汁的损耗角正切与糖度有较好的线性关系,其决定系数为0.784,但西瓜汁的介电特性与糖度的相关性较差;密瓜和西瓜果汁的糖度与果肉的含水率有很好的线性相关性,其决定系数分别为0.973和0.906。该研究将为基于介电特性的果汁糖度检测仪的开发提供了研究基础。 | 郭文川 Smart O.

| 2 | Method for converting in-situ gamma ray spectra of a portable Ge detector to an incident photon flux energy distribution based on Monte Carlo simulation显示文摘A matrix stripping method for the conversion of in-situ gamma ray spectrum, obtained with portable Ge detector, to photon flux energy distribution is proposed. The detector response is fully described by its stripping matrix and full absorption efficiency curve. A charge collection efficiency function is introduced in the simulation to take into account the existence of a transition zone of increasing charge collection after the inactive Ge layer. Good agreement is obtained between simulated and experimental full absorption efficiencies. The characteristic stripping matrix is determined by Monte Carlo simulation for different incident photon energies using the Geant4 toolkit system. The photon flux energy distribution is deduced by stripping the measured spectrum of the partial absorption and cosmic ray events and then applying the full absorption efficiency curve. The stripping method is applied to a measured in-situ spectrum. The value of the absorbed dose rate in air deduced from the corresponding flux energy distribution agrees well with the value measured directly in-situ. | Boubaker ASKRI Adel TRABELSI Brahim BACCARI | 2008 | Nuclear Science and Techniques2008，19，6： | 3 |
| 3 | Sensing grain and seed moisture and density from dielectric properties显示文摘The importance of moisture measurement in grain and seed is discussed,and a brief history of the development of moisture sensing instruments,based on sensing of dielectric properties of these materials,is presented.Data are presented graphically on the permittivities or dielectric properties of grain and seed showing their variation with frequency,moisture content,temperature,and bulk density,and references are cited for further information.More recent developments on microwave measurements for moisture content and bulk density sensing are briefly described,and numerous studies are cited providing sources of information on these newer techniques. | Stuart O.Nelson D.Sc.Samir Trabelsi | 2011 | International Journal of Agricultural and Biological Engineering2011，4，1： | 2 |
| 4 | 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 |
