With an explosive growth of e-businesses worldwide, e-commerce in China is booming, leading to the development of e-commerce education. This paper is intended to investigate whether the education system in China well accords with the market demand and the status of e-commerce programs in China, so as to seek for the strategies for China to cope with the challenges from the global e-commerce emp...

Adhesion differences are the main driver of cell sorting and related processes such as boundary formation or tissue positioning. In the early amphibian embryo, graded variations in cadherin density and localized expression of adhesion-modulating factors are associated with regional differences in adhesive properties including overall adhesion strength. The role of these differences in embryonic...

The G20, a grouping of the largest developed and developing economies in the world, accounts for almost 86% of global Gross Domestic Product and 76% of global CO2 emissions. In recent years, the G20 global summit has not only aimed to support an economic agenda, but also to coordinate actions towards a cleaner energy and low-carbon future. However, in different countries driving forces for the ...

introduction knowledge is continuously being produced in the process of formulating and implementing rural development projects. the capital is available without any cost, but it is neglected. knowledge has been distributed along the extensive network through the country. if knowledge management is recorded and exploited, it could lead to dramatic changes as a result of the butterfly approach. ...

The wavelength of moment of active forces (driving forces) for a full cycle while pedaling with platform pedals was determined. There was defined the value of moment of passive forces, depending on drag, rolling resistance and grade of surface. Kinematic motion parameters were determined from the equation of motion of the machine, which was solved numerically. In numerical example, there were d...

Lipid-protein interactions play pivotal roles in biological membranes. Electron crystallographic studies of the lens-specific water channel aquaporin-0 (AQP0) revealed atomistic views of such interactions, by providing high-resolution structures of annular lipids surrounding AQP0. It remained unclear, however, whether these lipid structures are representative of the positions of unconstrained l...

• We refine the database to include only proteins with TM helices. This includes alpha-helical polytopic and alpha-helical bitopic OPM classes as of September 2011 (357 TM proteins, 261 unique). The full list of MPs is available in Table S2. • We extract the structure of each such protein from the database. • We extract other supporting information on the protein such as the hydrophobic thickne...

Even though it’s well known that our common resources are limited and that recycling is key for a sustainable future; in reality we see few examples of true recycling where virgin raw material is substituted by waste. There are endless numbers of examples where waste is utilized to some extent without solving the core issue: reducing the need of extracting virgin raw materials. This article ana...

In the recent years, Software-as-a-Service has gained growing attention from software vendors as well as software customers. In this distribution and pricing model, software vendors are responsible for the operation and maintenance of solutions and customers pay for the service in form of continuous usage-based subscription fees. This study analyses the key characteristics of the Softwareas-a-S...
