Opis:
In this work a modular intelligent fixture system for flexible clamping of large parts is presented. The fixture modules consist of a hybrid material structure involving metal frame elements and mineral casting. These modules can be combined and connected to realize fixtures adapted to the geometry of the workpiece and requirements of the machining processes. By integrated pipes and interfaces, an internal hydraulic supply and active cooling is possible even for combined modules. Temperature and acceleration sensors allow for an active thermal control and process monitoring. The modules and first test fixtures are investigated in experiments.

Opis:
The Hoanh Bo Basin is a multiple period formed basin which is associated with the tectonic mechanism due to the activity of the Chi Linh-Hon Gai and Trung Luong Faults during the late Paleogene – early Neogene time. The basin is filled with continental sediments, comprising mainly polymictic conglomerates, sandstones, siltstones, claystones and shales. Coarser-grained polymictic deposits predominate along the northern and western margins of the basin, while different types of siltstones, claystones, even sandstones occur in its center, as well as along its southern and eastern parts toward the Ha Long Bay. The source rocks for sedimentary materials are mainly originated from rocks of the Hon Gai and Ha Coi Formations. Based on the dominant grain-size class, texture, stratification, degree of clast rounding and sorting, 17 lithofacies were determined in the Hoanh Bo Basin infill. The basin is filled by gravelly, sandy and fine-grained lithofacies just covers a modest area but it represents a full of succession of 4 depositional systems including alluvial fan, fluvial, deltaic and lacustrine environments. Alluvial fan and fluvial environments are characterized by an assemblage of lithofacies such as sand- and mud-supported disorganized breccias (Gb), clast- to sand-supported conglomerates (Gmm), clast-supported inverse-graded conglomerates (Gig), planar-cross-bedded conglomerates (Gp), trough cross-bedded conglomerates (Gt), horizontally stratified conglomerates (Gh), planar cross-bedded sandstones (Sp), trough cross-bedded sandstones (St), ripple cross-laminated sandstones (Sr), horizontally bedded sandstones (Sh), massive sandstones (Sm), massive mudstones, siltstones (Fsm), laminated siltstones and mudstones (Fl), massive claystones (Fm) and coaly lithofacies (C); the deltaic assemblage is dominated by planar-cross-bedded conglomerates (Gp), horizontally stratified conglomerates (Gh), planar cross-bedded sandstones (Sp), horizontally bedded sandstones (Sh), low-angle cross-bedded sandstones (Sl); while the lacustrine assemblage consists of ripple cross-laminated sandstones (Sr), horizontally bedded sandstones (Sh), normally graded sandstones (Sng), massive mudstones, siltstones (Fsm), laminated siltstones and mudstones (Fl), massive claystones (Fm) and coaly lithofacies (C).

Opis:
In this study, we investigated the fatty acid composition and anticancer activity of neutral and polar lipid fractions extracted from Crassostrea gigas oysters cultured in Nha Phu Lagoon, Khanh Hoa Coast, harvested during the five months of January, April, May, September, and November. Analysis revealed that saturated fatty acids (SFAs) were the most abundant fatty acids in the neutral lipid fraction, followed by monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (PUFAs). Conversely, the polar lipid fraction exhibited a different order, with PUFAs being the most abundant, followed by MUFAs and SFAs. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) were identified as the most prevalent polyunsaturated fatty acids, while oleic acid and palmitic acid were the predominant monounsaturated and saturated fatty acids, respectively. Notably, the combined content of EPA and DHA in the polar lipid fraction consistently exceeded 30% throughout all five months of analysis. Thrombogenicity index (TI) values ranged from 0.13 to 0.29 for the polar lipid fraction and from 0.6 to 1.1 for the neutral lipid fraction. Moreover, the polar lipid fraction exhibited significantly higher n3/n6 ratios compared to the neutral lipid fraction. The polar lipid fraction exhibited stronger inhibitory effects on the growth of the three cancer cell lines (HepG2, MDA-MB-231, and RD) compared to the neutral lipid fraction. The findings of the present study show that lipids extracted from C. gigas oysters cultured in Khanh Hoa Coast have a weak anticancer activity but may still aid in prevention and treatment of certain cancer types.

Opis:
The dielectric and mechanical properties of standard (PEI), nanoscale-filled and microscale-filled varnishes are detailed and analyzed in this communication. Two kind of silica (10 nm and 400 nm) have been tested as a filler. A particular attention has been paid to Partial Discharge Inception Voltage, lifetime under pulse voltage and bonding strength which are crucial for varnish to be used in rotating machines fed by inverters.
