Determination of Interlaminar Shear Properties of Fibre-Reinforced Composites under Biaxial Loading: A New Experimental Approach.

The complexity of biaxial tests and analysis of their results makes it difficult to study the interlaminar shear properties of fibre-reinforced composites, particularly under through-thickness compression, which occurs in thick-walled composite elements. The improvements in experimental methods to study the features of the nonlinear behaviour of composites under biaxial loading is now an important and relevant task in the development aircraft structural elements made of carbon fibre-reinforced polymers. This study aimed to develop a new experimental approach for the reliable determination of the interlaminar shear properties of laminates under through-thickness compression using a standard testing machine.

[Endovideosurgery (minimally invasive surgery) in treatment for malignant tumors of female genital organs: a 5-year experience of the clinic of the N.N.Petrov Research Institute of Oncology].

During the period of 2010-2015 laparoscopic surgery was performed in 1263 patients: 1113 with endometrial cancer (588 hysterectomies, 509 hysterectomies with pelvic lymphadenectomy, among them 16 with sentinel lymph node (SLN) mapping with Indocyanine green (ICG)); 86 with cervical cancer (80 nerve-sparing radical hysterectomies (NSRH), among them 15 with SLN mapping, 6 radical vaginal trachelectomies with endovideoassisted lymphadenectomy); 64 with ovarian malignancies. The average operating time in the group of hysterectomies was 101 minutes, in the group of hysterectomies with pelvic lymphadenectomy - 184 minutes, in the group of NSRH - 230 minutes. Average blood loss was less than 50 ml.

[Intraoperative intraperitoneal chemoperfusion treatment with cisplatin and dioxadet on a model of peritoneal carcinomatosis in ovarian cancer: safety and efficacy evaluation].

A comparative study of safety and efficacy of normothermic and hyperthermic intraperitoneal chemoperfusion (IPEC and HIPEC) with cisplatin and dioxadet was carried out in 143 female Wistar rats. Ovarian cancer was inoculated intraperitoneally (i.p.

[CHEMOPERFUSION TECHNOLOGIES IN TREATMENT FOR MALIGNANT TUMORS].

The data of literature on possibility of the use of perfusion technologies in combined treatment for malignant tumors of different sites are presented. Possible complications during hyperthermic chemoperfusion are discussed and the effectiveness of this method is analyzed.
