Ordered titanium dioxide nanotubes （TiOaNTs） modified with indium tin oxide （ITO） films were obtained via magnetron sputtering, in which ITO plate was used as a target, onto the as-anodized titania support followed by the calcination process. The morphology of fabricated material with deposited oxide was investigated using scanning electron microscopy. Raman and UV-Vis spectroscopies were utilized to characterize crystalline phase and optical properties of prepared samples, whereas X-ray photoelectron spectroscopy allowed determining the binding energy of present elements. In the case of titanium, three various oxidation states were identified and also the presence of indium and tin was confirmed. The electrochemical test carried out when the sample was exposed to light allows for selection of the most photoactive material. The highest photocurrent was registered when only 5-nm ITO layer was sputtered, and it equals 256 and 133 μA cm^-2 for the electrode material immersed in 0.5 M KOH and K2SO4 electrolytes, respectively, that is accordingly 3.5 and 4.4 times higher than the one observed for pristine titania. Furthermore, ITO-modified titania exhibits excellent photostability upon prolonged illumination that is of key importance for possible application in light-driven processes.

Identification of Modal Loss Factor of a Sandwich Composite Structure with Polyethylene Terephthalate Core in the Aspect of Core Properties Determination

引用

Materials Sciences and Applications 2015年第6期6卷 473-488页

作者： Krzysztof Marynowski katarzyna grochowska Division of Dynamics Lodz University of Technology Lodz Poland

Comparison of the loss factor determination methods of the sandwich composite structure with polyethylene terephthalate core in the aspect of core material rheological parameters identification was the purpose of the study. Three frequency bandwidths n dB: 1 dB, 2 dB, 3 dB methods, the resonant amplitude method and the fit method of the response of the one degree of freedom model system are taken into considerations. Identification procedure, according to ASTM E756-2005 [1] based on experimental studies of the forced vibrations of the composite structure was presented in the paper. To determine the function of the complex shear modulus of the core material, the Nelder-Mead method is applied. Shear modulus and loss factor identification results were presented on the plots in the frequency domain. The results in a quantitative manner set the applied methods and their practical utility in order.

Background:The metabolic syndrome is a consequence of modern lifestyle that causes synaptic insulin resistance and cognitive deficits and that in interaction with a high amyloid load is an important risk factor for Alzheimer’s *** has been proposed that neuroinflammation might be an intervening variable,but the underlying mechanisms are currently ***:We utilized primary neurons to induce synaptic insulin resistance as well as a mouse model of high-risk aging that includes a high amyloid load,neuroinflammation,and diet-induced obesity to test hypotheses on underly-ing ***:We found that neddylation and subsequent activation of cullin-RING ligase complexes induced synaptic insulin resistance through ubiquitylation and degradation of the insulin-receptor substrate IRS1 that organizes synap-tic insulin ***,inhibition of neddylation preserved synaptic insulin signaling and rescued memory deficits in mice with a high amyloid load,which were fed with a’western diet’.Conclusions:Collectively,the data suggest that neddylation and degradation of the insulin-receptor substrate is a nodal point that links high amyloid load,neuroinflammation,and synaptic insulin resistance to cognitive decline and impaired synaptic plasticity in high-risk aging.

Specificity of Food Security Concept as a Wicked Problem

引用

Journal of Agricultural Science and Technology(B) 2014年第10期4卷 823-831页

作者： Renata grochowska Institute of Agricultural and Food Economics National Research Institute Warsaw 00-002 Poland

The aim of the article was firstly to analyze a specific character of the food security＇s concept, and secondly to present a large variety of stakeholders＇ positions dealing with the issue and their impact on economic and political dimensions. For this purpose, a review in available studies and documents was made. The results show that a lack of the precise definition for the food security＇s concept creates different understandings, leading to various interpretations and divergent solutions. The reasons could be found in specifics of the food security＇s concept which is qualified as a wicked problem. Wicked problems refer to issues which are highly complex, have innumerable and undefined causes and are difficult to understand and frame. Therefore, caution is required when positions of stakeholders are estimating. Based on literature, it can be stated that the productionist （focusing on intensive food production） and environmental frames are dominant in the debate, resulting in potential conflicts and different claims about action to be taken. As a result, a clear political vision on the food security＇s concept is lacking. In conclusion, a return to the principle what food production is economically, socially and environmentally sustainable can reshape a public debate in order to actively form food security policies at the global and national levels in the future. However, better coping strategies like cooperative strategy should be developed to tame food security as a wicked problem by turning over to stakeholders for new definitions and solutions.

关键词： Food security wicked problem stakeholders' positions.
