    Opis:
    Mikroinnowacje, jako rodzaj innowacyjnego sposobu myślenia i proces innowacyjny, można podzielić na mikroinnowacje ciągłe, imitacyjne i niezależne. Podział ten oparty jest na wymiarach innowacyjności, zakłóceń rynku i powtarzalności w dziedzinie innowacji. Na podstawie badań teoretycznych i empirycznych w artykule dokonano analizy wpływu głównych determinant mikroinnowacji na kształtowanie ich typów. Determinanty te, do których należą zasoby produktywne, zasoby zarządcze i ograniczenia zewnętrzne, wywierają bardziej znaczący wpływ na mikroinnowacje imitacyjne, a jednocześnie wykazują mniejszą korelację z mikroinnowacjami niezależnymi i ciągłymi. Wdrażając mikroinnowacje, przedsiębiorstwa powinny wybrać odpowiedni typ lub odpowiednie kombinacje różnych typów mikroinnowacji na podstawie kompleksowej analizy wewnętrznych zasobów produktywnych, zasobów zarządczych oraz ograniczeń zewnętrznych.
    Micro-innovation, a kind of innovative thinking and innovative manner, can be divided into continuous micro-innovation, imitating micro-innovation and independent micro-innovation based on the dimensions of innovativeness, market disruption and repetitiveness in the innovation domain. On the basis of theoretical and empirical research, this paper analyzes the impact of the main micro-innovation affecting factors on micro-innovation types. Affecting factors including productive resources, management resources and external restrictions have a more prominent impact on imitating micro-innovation, while having a lower correlation with independent micro-innovation and continuous micro-innovation. Enterprises should select an appropriate micro-innovation type or different type combinations according to the comprehensive analysis of enterprise internal productive resources, management resources and external restrictions when implementing micro-innovation.

    Opis:
    The main objective of the study was to evaluate the effect of added 0.3% (w/w) oat β-glucan (OG) in set-type yogurt on its protein digestion using an in vitro gastrointestinal model. During gastric digestion phase, the amount of soluble proteins and peptides increased to 25% and 40% for control yogurt (yogurt without OG) and 0.3% OG yogurt, respectively. Buccal digestion has little effect on the structure of yogurts, while large spherical vesicles were formed for both control yogurt and 0.3% OG yogurt after gastric digestion. The presence of 0.3% OG promoted the hydrolysis of yogurt in the gastric digestion phase and caused higher antioxidant activity. Compared with that of control yogurt, the inhibition of cholesterol solubility of 0.3% OG yogurt showed no differences after buccal digestion but significantly higher after gastrointestinal digestion (21.3% for gastric and 22.7% for intestinal digestion). Overall, this study enhances the understanding of digestion characteristics of 0.3% OG-fortified set-type yogurt and provides a theoretical basis for the development of this kind of dairy products.

    Opis:
    In multi-axis motion control systems, the tracking errors of single axis load and the contour errors caused by the mismatch of dynamic characteristics between the moving axes will affect the accuracy of the motion control system. To solve this issue, a biaxial motion control strategy based on double-iterative learning and cross-coupling control is proposed. The proposed control method improves the accuracy of the motion control system by improving individual axis tracking performance and contour tracking performance. On this basis, a rapid control prototype (RCP) is designed, and the experiment is verified by the hardware and software platforms, LabVIEW and Compact RIO. The whole design shows enhancement in the precision of the motion control of the multi- axis system. The performance in individual axis tracking and contour tracking is greatly improved.

    Opis:
    Flotation optimal conditions and mechanism of regulator lime, isopentyl xanthate and butyl xanthate on pyrrhotite were investigated by flotation test, contact angle, zeta potential and infrared spectroscopic analysis. It is found that there is a certain relationship between the regulator lime and the collector isopentyl xanthate. The results of flotation indicate that lime can indeed inhibit pyrrhotite, and isopentyl xanthate can decrease the depression effect of lime on pyrrhotite in low alkalinity. The results of adsorption mechanism of lime and isopentyl xanthate show that after lime adsorbed on the pyrrhotite surface, Ca 2+inhibit the adsorption of collector with the form of Ca(OH) 2 precipitates. Compared with butyl xanthate, isopentyl xanthate could reduce the generation of hydrophilic Ca(OH) 2 and generate less hydrophilic CaCO3 as well to decrease the negative effect of gold-bearing pyrrhotite flotation depressed by lime.

    Opis:
    Rat robots have great potential in rescue and search tasks because of their excellent motion ability. However, most of the current rat-robot systems relay on human guidance due to variable voluntary motor behaviour of rats, which limits their application. In this study, we developed a real-time system to detect a rat robot’s transient motion states, as the prerequisite for further study of automatic navigation. We built the detection model by using a wearable inertial sensor to capture acceleration and angular velocity data during the control of a rat robot. Various machine learning algorithms, including Decision Trees, Random Forests, Logistic Regression, and Support Vector Machines, were employed to perform the classification of motion states. This detection system was tested in manual navigation experiments, with detection accuracy achieving 96.70%. The sequence of transient motion states could be further used as a promising reference for offline behaviour analysis.

    Opis:
    The oxygen-containing functional groups (OCFG) on the coal surface affect the adsorption effect of hydrocarbon oily collectors (HOC). An investigation of the interaction between the HOC and OCFG in the absence and presence of water is conducive to understanding the effect of OCFG type on the adsorption of HOC on the coal surface. In this paper, FTIR analysis was used to analyze the OCFG type of coal surface. The adsorption behavior of HOC on different OCFG surfaces was investigated using molecular dynamics simulation. The results indicated the presence of OCFG such as -OH, -COOH, -C=O, and -COCH3 on the coal surface. In conditions without water, the effect of OCFG on HOC adsorption capability follows the order -COOH > -C=O > -OH > -COCH3. In an aqueous solution, the effect of OCFG on HOC adsorption capability follows the order -C=O>-COCH3>-OH>-COOH. Moreover, the hydrophilicity of OCFG is the key factor that affects the adsorption effect of HOC. In other words, the adsorption effect of HOC on the coal surface in an aqueous solution does not depend on the strength of the interaction between the OCFG and HOC in the absence of water, but on the hydrophilicity of the OCFG. The -COOH and -OH on the coal surface are not conducive to the adsorption of HOC onto the coal surface. Masking the -COOH and -OH of the coal surface is beneficial in improving the coal flotation performance with HOC as a collector.

    Opis:
    Oleic acid (OA) is widely used in pathology studies of hepatocellular lipid deposition. Identifying the effects of different solvents on OA-induced liver lipid deposition would be beneficial for studies on hepatocytes. We treated BRL 3A cells with OA dissolved in different solvents. After 12 h incubation, cell viability was assessed using MTT assays. Reactive oxygen species (ROS), triglyceride (TG) and total cholesterol (TC) counts, and the expression level of glucose regulated protein (GRP78), sterol regulatory element binding protein (SREBP-1C) and fatty acid synthase (FAS) were analyzed. Water, PBS and DMSO were disadvantageous to the dissolution of OA and did not cause an OA-induced response in hepatocytes. In the alcohol+OA-treated cells, the severe ER stress, oxidative stress and cellular fat deposition were significantly increased. BSA promoted cell growth and the cells treated with 1.2% BSA+OA showed a lower grade TG and endoplasmic reticulum stress compared with KOH+OA and alcohol+OA treatments. KOH had no significant influence on BRL 3A cells viability. When treated with OA dissolved in KOH, BRL 3A cells showed a typical hepatocyte damage. KOH was considered the suitable choice for an OA solvent for BRL 3A cells in hepatic lipidosis research.
