Originality/value As far as the authors are aware, this is the first time that a study has been carried out in the Portuguese energy sector using the GMM-system model for three different stakeholders' views of corporate performance determinants.Maria Elisabete Duarte Neves...
For the past 15 years, a class of materials known as topological insulators has dominated the search for the materials of the future. These crystals have an uncommon property: Their interiors are insulators — where electrons cannot flow — but their surfaces are perfect conductors, where electrons...
How does the process of photosynthesis impact the flow of energy? Give a clear and concise definition of photosynthesis. What is the equation of photosynthesis, and how does that help us find its process in biology? Describe the process of photosynthesis using a drawing/picture. ...
the senior positions and with few appointments made from outside the company to important roles. When the company grew to a certain size, Mr Mara decided that he needed a qualified accountant on the board of directors to help with investment appraisals, costings, cash flow management, ...
aIt also helps to explain why Brazil, achieving a net energy ratio of 8 from bagasse, can produce ethanol at about half the cost of producing it from corn in the United States. 它也幫助解釋為什麼巴西,達到一個淨能比率8從蔗渣,在美國可能生產對氨基苯甲酸二在一半導致它的大約費用由玉米。[trans...
When you stand the toothbrush on its charger, how does the electricity flow from its plastic-coated base into the battery inside the brush when plastic is an insulator (that is, doesn't allow electricity to flow through it)?It's not magic we have here—it's just another kind of ...
aCould not flow the tear, you asked me, the final tear did flow for who.In order to you flow. 不可能流动泪花,您要求我,最后的泪花为谁流动了。为了您流程。[translate] a他适应不了新环境 He could not adapt to the new circumstances[translate] ...
How this surface actin layer drives the various gliding modes observed in experiments—helical, circular, twirling and patch, pendulum or rolling—is unclear. Here we suggest that F-actin flows arise through self-organization and develop a continuum model of emergent F-actin flow within the ...
Describe the flow of energy from a glucose molecule to ATP during respiration. What is the use of the oxygen in cellular respiration? Explain why cellular respiration involves so many molecules and steps based on how life obeys and exploits the Laws of Thermodynamics. In cellular respiration, the...
