Livingstone, Couvering and Thumim (2006) described 6 key demographic barriers preventing senior citizens from accessing new technology: includes age, socio-economic status, gender, disability, ethnicity and proficiency in English [12].
All these studies showed that those 6 key demographic barriers were users’ individual differences.

Impact of continuous Cucumis sativus L. cropping on the incidence of root diseases and bacterial community structure Yuansen Hu1,a, Cuixiang Li1,b and Likun Gu2,c 1Faculty of Bioengineering, Henan University of Technology, Zhengzhou, China 2College of Resource and Environment Science, Henan Institute of Engineering, Zhengzhou, China ahys308@126.com, blicuixiang2005@126.com, cgulikun1@163.com Keywords: Continuous cropping, Cucumber, Rhizosphere, Root disease, Bacterial community Abstract: To investigate the change of cucumber root disease incidence and bacterial community shift in monocultrue soil, we established 4 treatments of greenhouse-pot cucumber, each representing various monoculture times, and monitored the bacterial variation in rhizosphere/bulk soil and root disease index.
Work by van Elsas et al[12] also showed that agronomical practices significantly affected soil microbial diversity, and the microbial communities diversity could be a possible key to the capacity of a soil to suppress the soilborne potato pathogen R. solani AG3.
Materials and methods Soil, plant conditions and sampling The trial field was located at the Vegetable Experimental Center of Henan province, China.
A key characteristics of this genus was its ability to degrade a wide range of polycyclic aromatic hydrocarbons (PHAs), of which the intermediary degradation products were often regarded as important allelochemicals in cucumber exudates, and potentially stunted plant root growth[5,32].

Introduction One of the key approaches for minimizing the likelihood of wound infection is the use of topical antimicrobial agents.
Therefore, inorganic nanostructured materials on textile have to be stabilized [7] which is occasionally achieved by incorporation of nanometallic particles into organic polymers.
Therefore, polysiloxanes hold particular position for biomedical materials and have a diversity of applications.

Many engineering processes such as fossil fuel combustion energy processes, solar power technology, astrophysical flows and space vehicle re-entry occur at high temperature.
In recent years, heat transfer due to convective surface over various geometries has received considerable attention for its potential applications in several engineering and industrial processes like transpiration cooling process, material drying, etc.

Introduction The operating principle of chemiresistive gas sensors is based on the resistive changes of the sensing material layer, which is controlled by the adsorption/desorption processes of the analytic gas molecules as well as oxygen ions on the surface of the sensing material [1].
At such high operating temperatures, metal oxides were considered the most potential candidate for the sensing material layer.
As suggested from the measurements of chemical, morphological, structural, and gas-sensing properties, the opposite catalytic property of Rb2CO3 toward CO and H2 plays a key role in creating the ultrasensitivity of the CuO/Rb2CO3 nanohybrid structure to CO over H2.

AlCrFeNi High-Entropy Coating Fabricated by Mechanical Alloying and Hot Pressing Sintering Caiyun Shanga and Yan Wangb School of Materials Science and Engineering, University of Jinan, No. 336, West Road of Nan Xinzhuang, Jinan, 250022, China.
All these properties show promising prospect for engineering applications.
However, the cost may be increased significantly if some expensive elements were involved in the synthesis of HEAs bulk materials.
Therefore, fabrication of high entropy coating alloys (HEACs) on commonly used substrate materials, such as Q235 steel, provides an economical and promising method in reducing the cost and enhancing the material surface properties.
