Giant Dielectric Permittivity and Magnetocapacitance in La\u3csub\u3e0.875\u3c/sub\u3eSr\u3csub\u3e0.125\u3c/sub\u3eMnO\u3csub\u3e3\u3c/sub\u3e Single Crystals

We report the observation of extremely high dielectric permittivity exceeding 109 and magnetocapacitance of the order of 104% in La0.875Sr0.125MnO3 single crystal. This phenomenon is observed below 270 K, and it exhibits a history dependence. These effects may be the consequence of strong competition and interplay among the charge, orbital, and spin degrees of freedom, resulting in nanoscale charge and spin dynamic inhomogeneities in the prepercolation regime of the phase segregation

Photoconductivity and photostimulated currency in PMN-PT

© 2017 Taylor & Francis Group, LLC.The photoconductivity and the photostimulated currency were measured in PMN-PT single crystals. Based on the experimental data, the characteristics of the density of states of the defect levels and the possibility of their participation in the formation of a diffuse phase transition are discussed

Эндопротез нижней челюсти с опорными зонами как искусственный орган

Mandibular reconstruction after partial or complete resection is a prerequisite for restoring normal facial aesthetics, articulation and chewing function. We present a clinical case of lower jaw reconstruction in a female patient with acquired extensive bone defect while taking pervitin and desomorphine. Detailed descriptions of the stages of planning and performing surgery, manufacture of an individual endoprosthesis, as well as preoperative preparation of the patient are presented. Clinical and radiological data in the postoperative period were analyzed and an objective assessment of the effectiveness of the technique was given. Adequate restoration of the main functions of the lost organ was achieved thanks to the use of an individual titanium mandibular endoprosthesis with integrated dental implants and a full-arch denture.Реконструкция нижней челюсти после ее частичной или полной резекции является необходимым условием для восстановления нормальной эстетики лица, артикуляции и жевательной функции. В данной публикации представлен клинический случай реконструкции нижней челюсти у пациентки с приобретенным обширным дефектом кости на фоне приема наркотических веществ на основе первитина и дезоморфина. Приведено детальное описание этапов планирования и проведения оперативного вмешательства, изготовления индивидуального эндопротеза, а также предоперационной подготовки пациента. Проанализированы клинические и рентгенологические данные в послеоперационном периоде, дана объективная оценка эффективности методики. За счет применения индивидуального титанового эндопротеза нижней челюсти с включенными дентальными имплантатами и изготовления ортопедической конструкции достигнуто адекватное восстановление основных функций утраченного органа
