“…In this case it would rain continuously everywhere over the ocean. Such a unidirectional gas flow is realized in heat pipes -technological devices that employ the partial pressure gradient of the saturated vapour to effectively transfer heat (Grover et al, 1964). The rapid transport of heat along the pipe is due to the difference in partial pressures of saturated vapour within the pipe, as one end of the pipe is warm, another is cold; this pressure gradient causes the vapour to flow very rapidly along the tube from the hot end to the cold.…”

Intense condensation associated with high evaporation from natural forest cover maintains regions of low atmospheric pressure on land. This causes moist air to flow from ocean to land, which compensates the river runoff. Deforestation induces large-scale desiccation by disrupting this flow. Here we overview this theory and quantify the horizontal pressure gradients that govern the continental moisture supply. High evaporation and large extent of natural forests guarantee both a stable and high throughput hydrological cycle. Forests protect a continent against devastating floods, droughts, hurricanes, and tornadoes. Sustaining natural forests is a sound strategy for water security and climate stabilisation.

“…Initially we designed an oven with a glass cell containing the Na, but after some time the Na reacted with the glass. After this, we built a heat pipe oven [52][53][54], using a crossed heat pipe design [55]. The heat pipe oven design allows us to have high pressures of Na while preventing the Na from reaching the optical windows.…”

The work presented in this thesis is geared towards the understanding of coherent control in molecules and atoms in strong fields. The analysis is done by studying multiphoton transitions. We present a theoretical model that describes multiphoton transitions under strong fields. We show that in order to achieve population inversion a phase-matching condition between the laser and the atom needs to be satisfied. This phase matching condition shows that fields need to be tailored taking into account the presence of the dynamic stark shift (DSS) effect and compensating for it. These findings are corroborated by experimental results and simulations. Experimentally, we used a genetic algorithm (GA) to find pulse shapes that can efficiently excite atomic Na to the 4s state by means of a two photon absorption. The solutions found by the GA are used directly to integrate Schrödinger's equations for the amplitudes. The results of using this scheme ratify our theoretical model. We also map how the transition from the weak to the strong field limit occurs for two and three level systems in the presence of multiphoton transitions. Here, we show that the perturbative solutions are a particular case of our model and they are recovered in iii

“…Since the invention of the heat pipe in 1963 (Grover et al 1964), numerous mathematical models of heat pipe operation have been developed. These investigations range in complexity from simple state-to-state thermodynamic analyses (Khalkhali et al 1999;Richter and Gottschlich 1994;Zuo and Faghri 1997) to transient, multidimensional computational models of the fluid flow and heat transfer in the liquid and vapor phases (Cao and Chang 1997;Cao and Faghri 1991;Cao and Faghri 1993;Tournier and El-Genk 1994;Tournier and El-Genk 1996;Tournier and El-Genk 2003).…”
