Factors affecting the rate of photosynthesis must either change the CO 2 diffusive resistances or the CO 2 concentration gradient along the diffusion pathways. Therefore, these effects can be described in terms of diffusive control mechanisms. Light affects CO 2 diffusion by initiating photosynthesis, ...

There is no measurable change in the properties of the mutant luminescence with changes in excitation wavelength extending to 708 nm, leading us to conclude that Photosystem I contributes less than 5% of the emission 10 ms after excitation. This limit on the intensity of emission from Photosystem...
Silicon electrodes in lithium-ion batteries are severely limited by the stress that arises from large volume changes during cycling. Here, authors exploit the inherent volume change dynamics of silicon and sulfur electrodes and design a stress-neutralized solid-state battery. ...
B) It is the change in speed of a falling object.C) It is the amount of energy in the solar system.D) It is the ability to move an object.2.Why does the professor talk about a plow?A) To describe recent improvements in agricultural technology.B) To explain what happens when a ...
The Proceedings of the 14th International Congress on Photosynthesis is a record of the most recent advances and emerging themes in the discipline. This volume contains over 350 contributions from some 800 participants attending the meeting in Glasgow, UK in July 2007. These range from summary overv...
A change in protein morphology on chimera formation could be observed by transmission electron microscopy (TEM). Images of a mix of unadapted WT RCs and dLHCII showed a large number of monodispersed, regularly sized objects of <10 nm diameter (Fig. 3g, top/left), whereas images of the ...

Any change in albedo will, of course, have an effect on Earth’s energy budget.The portion of incoming solar energy that is not reflected back into space, along with tidal and geothermal energy, is absorbed by materials at Earth’s surface, in particular the atmosphere and hydrosphere. This...
Thus, from energy and momentum conservation considerations, the deflected photon undergoes negligible loss of energy or change in wavelength. Since the angular distribution Rayleigh scattering is sharply peaked in the forward direction for photon energies in the gamma-ray region, and the energy loss ...
