Homogeneous Catalyst Recycling and Separation of a Multicomponent Mixture Using Organic Solvent Nanofiltration

In homogeneous catalysis, the application of organic solvent nanofiltration (OSN) has become a well-known alternative to common recycling methods. Even though some OSN membranes are commercially available, their classification and the scope of application have to be determined for the specific solvent mixture. The commercial membrane Evoniks DuraMem® 300 was tested in a mixture of ethanol, ethyl acetate, and cyclohexane with magnesium triflate as possible catalyst. The cross permeate fluxes were measured for two transmembrane pressures and the hydrodynamic radii of the components were determined. Some of the components in the ternary mixture are retained, which makes the membrane also suitable for fractioning thereof. © 2019 The Authors. Published by WILEY-VCH Verlag GmbH & Co. KGaA, Weinhei

Microstructure analysis of titanium oxynitride films deposited by reactive magnetron sputtering

This paper presents the structure analysis results of TiOxNy films, deposited using reactive magnetron sputtering with different O2/N2 flow ratio. The impact of increase of N2 flow upon the films structure has been studied. The analysis was carried out by X-ray diffraction method. The lattice parameters and phase composition were calculated using PowderCell 2.4

Методы ремонта дефектных участков линейной части магистральных газопроводов

В процессе исследования были рассмотрены методы обследования, и ремонта дефектных участков линейной части магистральных газопроводов, с целью выявления эффективных методов ремонта с учетом рекомендации ДДО. Так как сканер дефектоскоп с некоторой не точностью показывает расположение и размер дефектов, а также при обследовании бывает, что дефекты не подтверждаются.In the process of investigation, the methods of inspection and repair of defective sections of the linear part of the main gas pipelines were considered, in order to identify effective repair methods, taking into account the recommendation of the ADC. Since the scanner flaw detector with some inaccuracy shows the location and size of defects, and also during the inspection it happens that the defects are not confirmed

Применение импульсного питания для сварки магистральных трубопроводов

Был проведен анализ напряженно-деформированных состояний моделей магистрального трубопровода, со сварным швом выполненным с разделкой кромок под шестьдесят градусов сваркой в СО2 и со сварным швом выполненным сваркой с применением импульсного питания в среде СО2 со щелевой разделкой кромок. Так же были рассчитаны некоторые параметры создания сварных соединений.An analysis was made of the stress-strain states of models of the main pipeline, with a welded seam made with cutting edges at sixty degrees by welding in CO2 and with a welded weld made using pulsed power in a CO2 medium with slotted cutting edges. Also, some parameters for creating welded joints were calculated

Gene expression profiling of mucinous ovarian tumors and comparison with upper and lower gastrointestinal tumors identifies markers associated with adverse outcomes.

PURPOSE: Advanced-stage mucinous ovarian carcinoma (MOC) has poor chemotherapy response and prognosis and lacks biomarkers to aid stage I adjuvant treatment. Differentiating primary MOC from gastrointestinal (GI) metastases to the ovary is also challenging due to phenotypic similarities. Clinicopathologic and gene-expression data were analyzed to identify prognostic and diagnostic features. EXPERIMENTAL DESIGN: Discovery analyses selected 19 genes with prognostic/diagnostic potential. Validation was performed through the Ovarian Tumor Tissue Analysis consortium and GI cancer biobanks comprising 604 patients with MOC (n = 333), mucinous borderline ovarian tumors (MBOT, n = 151), and upper GI (n = 65) and lower GI tumors (n = 55). RESULTS: Infiltrative pattern of invasion was associated with decreased overall survival (OS) within 2 years from diagnosis, compared with expansile pattern in stage I MOC [hazard ratio (HR), 2.77; 95% confidence interval (CI), 1.04–7.41, P = 0.042]. Increased expression of THBS2 and TAGLN was associated with shorter OS in MOC patients (HR, 1.25; 95% CI, 1.04–1.51, P = 0.016) and (HR, 1.21; 95% CI, 1.01–1.45, P = 0.043), respectively. ERBB2 (HER2) amplification or high mRNA expression was evident in 64 of 243 (26%) of MOCs, but only 8 of 243 (3%) were also infiltrative (4/39, 10%) or stage III/IV (4/31, 13%). CONCLUSIONS: An infiltrative growth pattern infers poor prognosis within 2 years from diagnosis and may help select stage I patients for adjuvant therapy. High expression of THBS2 and TAGLN in MOC confers an adverse prognosis and is upregulated in the infiltrative subtype, which warrants further investigation. Anti-HER2 therapy should be investigated in a subset of patients. MOC samples clustered with upper GI, yet markers to differentiate these entities remain elusive, suggesting similar underlying biology and shared treatment strategies
