Method of fish quality preservation at deep handling of raw materials

Deep cutting of fish raw materials is a priority for fish processing enterprises. The the influence of high-pressure processing of fish fillets has been studied and it has been shown that the impact of pressure above 100 MPa leads to a decrease in the total contamination by microorganisms. Further increase in pressure leads to an even greater decrease in the total number of microorganisms. The structural and mechanical properties of the fillet change slightly. High pressure makes the fish’s muscle tissue more dense. Pressure-treated fillets supposed to be stored chilled or frozen for much longer, since their initial quality indicators are much higher than those of fillets not treated with high pressure. The possibility of enriching the whole muscle tissue of fish with vegetable oil lipids when exposed to high pressure is shown

Cutting technologies for hard-machinable materials: Presentation held at International Scientific-Technical Forum "Modern Trends in Technologies and Design of Metal Working Equipments", 17. Juni 2014, Moskow

Der Aspekt der Ressourceneffizienz gewinnt bei der Entwicklung neuer Produkte sowohl in der Herstellungs- als auch Nutzungsphase an Dominanz. Der Einsatz hochfester, schwer bearbeitbarer Werkstoffe als auch die Herstellung hochkomplexer Bauteilgeometrien gewinnt an Bedeutung. Die in einer konventionellen Prozessoptimierung erörterten technischen Möglichkeiten sind oft unzureichend, in vielen Fällen kann die geforderte Bearbeitungsaufgabe mit klassischen Fertigungsverfahren nicht mehr realisiert werden. Die Verschiebung bestehender Verfahrensgrenzen bedarf neuer technologischer und technischer Ansätze. Durch hybride Prozesse können signifikante Verbesserungen in der Zerspanbarkeit von Werkstoffen, in der Span- und Gratbildung, in der erreichbaren Bauteilqualität sowie in der Produktivität bzw. Leistungsfähigkeit von Fertigungsverfahren erreichen. Im Beitrag werden innovative Zerspanungstechnologien und Applikationsbeispiele erörtert, Aufbauprinzipien dargestellt und Bearbeitungsergebnisse diskutiert

Ventilation-Associated Particulate Matter Is a Potential Reservoir of Multidrug-Resistant Organisms in Health Facilities

Most healthcare-associated infections (HCAIs) develop due to the colonisation of patients and healthcare workers by multidrug-resistant organisms (MDRO). Here, we investigated whether the particulate matter from the ventilation systems (Vent-PM) of health facilities can harbour MDRO and other microbes, thereby acting as a potential reservoir of HCAIs. Dust samples collected in the ventilation grilles and adjacent air ducts underwent a detailed analysis of physicochemical properties and biodiversity. All Vent-PM samples included ultrafine PM capable of reaching the alveoli. Strikingly, >70% of Vent-PM samples were contaminated, mostly by viruses (>15%) or multidrug-resistant and biofilm-producing bacterial strains (60% and 48% of all bacteria-contaminated specimens, respectively). Total viable count at 1 m from the ventilation grilles was significantly increased after opening doors and windows, indicating an association between air flow and bacterial contamination. Both chemical and microbial compositions of Vent-PM considerably differed across surgical vs. non-surgical and intensive vs. elective care units and between health facilities located in coal and chemical districts. Reduced diversity among MDRO and increased prevalence ratio in multidrug-resistant to the total Enterococcus spp. in Vent-PM testified to the evolving antibiotic resistance. In conclusion, we suggest Vent-PM as a previously underestimated reservoir of HCAI-causing pathogens in the hospital environment

Technologies for micro- and precision machining applications: Presentation held at International Specialized Exhibition Metalloobrabotka, 23.-27.05.2016, Moscow

The use of microstructures or functional surfaces in powertrain components or molds and dies has attained increasing significance. Also the relevance of micro parts for various applications is still growing worldwide. Technologies for micro and precision machining applications are also becoming increasingly important in batch production. Main applications are primarily in the micro-analysis, automotive, medical engineering and watch-making industries. Customers are increasingly demanding equipment (machine tools, cutting tools, machining strategies and process chains) capable of machining high-strength and hardened materials. Reliable and repeatable micro and precision machining technologies, especially in cutting processes, are targeted in the framework of Russian-German innovative cooperation projects. Project cooperation is concentrating on strategies to meet requirements of micro-hard milling operations conducted on materials up to 65 HRC, further on diamond machining of non-ferrous metals for applications with highest demands on accuracy and surface quality. The main focus is on feasibility, tool wear, process reliability and consistency. Systematic developments take place in: Customized milling strategies, milling cutter displacement, cutting forces and cutting value optimization and lubrication concepts for micro-machining. The associated machine tools are also part of investigations to guarantee required geometrical tolerances and surface qualities for micro and precision applications. In this context machine tools for cutting processes (µ-milling, µ-drilling, fly-cutting, nano-hobbing) and ablation processes (µ-laser, µ-EDM and ECM) are developed and enhanced by Kugler GmbH, ENIMS/ISTC TIM and Fraunhofer IWU

Synergy Effect of Combining Fluorescence and Mid Infrared Fiber Spectroscopy for Kidney Tumor Diagnostics

Matching pairs of tumor and non-tumor kidney tissue samples of four patients were investigated ex vivo using a combination of two methods, attenuated total reflection mid infrared spectroscopy and fluorescence spectroscopy, through respectively prepared and adjusted fiber probes. In order to increase the data information content, the measurements on tissue samples in both methods were performed in the same 31 preselected positions. Multivariate data analysis revealed a synergic effect of combining the two methods for the diagnostics of kidney tumor compared to individual techniques
