A multiple equilibriums poverty trap model is developed to analyse the effectiveness of State policy in developing and applying policies aimed at reducing poverty, i.e. pro-poor policies. The implication of this model is that, if poverty is concentrated in agriculture, then a necessary key to breaking out of the low level trap situation (where the State is ineffective in carrying out pro-poor p...

In photosystem II of green plants the key photosynthetic reaction consists of the transfer of an electron from the primary donor called P680 to a nearby pheophytin molecule. We analyzed the temperature dependence of this reaction by subpicosecond transient absorption spectroscopy over the temperature range 20-240 K using isolated photosystem II reaction centers from spinach. After excitation in...

Based on the multi-level model, we have calculated light shifts for Zeeman states of hyperfine levels of cesium (Cs) 6S1/2 ground state and 6P3/2 excited state. The magic-wavelength linearly-polarized optical dipole trap (ODT) for Cs 6S1/2 |F = 4, mF = + 4ñ - 6P3/2 |F' = 5, mF = + 5ñ transition is experimentally constructed and characterized by using the laser-induced fluorescence spectra of tr...

Abstract The $$\beta $$ β -delayed $$\gamma γ spectroscopy of $$^{81}$$ 81 As has been performed using a purified beam Ge $$(9/2^+)$$ ( 9 / 2 + ...

The efficiency of different types of traps for catching of the Caspian Sea crayfish, Astacus leptodactylus eichwaldi, was investigated from Mar. 2002 to Feb. 2003. Totally 56 traps of four most commonly used types, "Rectangular trap", "Round trap", "Opera house trap" in two colors of "black" and "blue", and "Fathoms plus" only in black...
