Understanding the link between chromatin structure, chromosome conformation and gene regulation
Understanding the connection between DNA organization in the nucleus, and cell functioning is one of the most intriguing problems in biology. Although many interdisciplinary efforts have been developed for this aim, the ...
Understanding the measurements and variability of aerosol optical properties in NE Spain
[eng] Atmospheric aerosol particles are key for regulating Earth’s atmosphere processes, and are estimated to present an overall cooling effect on the Earth’s climate. Given the current climate change crisis, and the need ...
Understanding the mechanisms of de novo gene evolution using transcriptomics data
Aquesta tesi investiga els mecanismes de formació i evolució de gens de novo utilitzant seqüenciació massiva de transcrits complerts i de fragments protegits per ribosomes. Hem identificat milers de gens de novo en humans ...
Understanding the mechanisms of drought-induced mortality in trees
Les plantes estan exposades a diversos estressos ambientals incloent la sequera i temperatures extremes els quals poden limitar el seu creixement i supervivència. La disponibilitat d'aigua es considera el principal factor ...
Understanding the mechanisms of food intake and obesity in Down syndrome is supported by behavioral and neurochemical abnormalities
Obesity prevalence is higher in Down syndrome (DS) than in the general population. Beyond metabolic alterations, individuals with DS present increased impulsivity, a trait observed in obese people and in compulsive eaters ...
Understanding the mobility of caesium, nickel and selenium released from waste disposal : chemical retention mechanisms of degraded cement
Cementitious materials are used to condition or stabilise waste and to build infrastructure in disposal sites. Moreover, they are envisaged to form part of engineered barrier systems as container, backfill or liner materials ...
Understanding the molecular basis of neuronal 3'UTR length-dependent mRNA sorting
The local translation of messenger RNAs (mRNAs) within different neuronal compartments is a prerequisite the formation of long-term memories. mRNAs are localized via active transport along microtubules, however, the ...
Understanding the motivational mechanisms of value congruence
Antecedents:Malgrat la importància oferta en la literatura, el concepte de congruència de valors és encara poc conegut. La literatura és ambigua i el tema és encara poc conegut. La congruència de valors es tracta a les ...
Understanding the nationalization of party
This thesis is focused on the nationalization of party systems in Western Europe and combines four different approaches. Despite the literature claiming that political decentralization reduces party system nationalization, ...
Understanding the optical and electronic properties of organic semiconductors using high pressure
En esta tesis se estudian las propiedades ópticas de semiconductores orgánicos, que pueden usarse en diodos orgánicos de emisión de luz (OLEDs; de la expresión inglesa) y células solares orgánicas (OSCs; de la expresión ...
Understanding the physical origin, topology and strength of noncovalent interactions by means of computational tools
The structure and stability of molecules, the formation of supramolecular aggregates in the solid state or in solution and, therefore, many chemical and biological processes in which they participate depend heavily on ...
Understanding the physiological mechanisms of drought-induced decline in Scots pine (Pinus sylvestris L.)
Durant les darreres dècades s’han documentat arreu del món múltiples casos de mortalitat forestal produïda per sequera i és probable que aquests augmentin amb el canvi climàtic, particularment en aquelles zones on la ...
Understanding the political integration outcomes of enfranchised and high socioeconomic status immigrants in host societies
The purpose of this dissertation is to systematically investigate the theoretical perspective that political power derives from socioeconomic power—a fundamental tenet of both sociological theories of assimilation and ...
Understanding the processes that controlled rifting of the Tyrrhenian basin
This thesis is focused in the processes that took place in the Tyrrhenian Sea, which is a Neogene basin belonging to the Western Mediterranean realm. Its formation is related with the subduction system of the African plate ...
Understanding the processes that shape the genetic diversity of freshwater planarians (Platyhelminthes, Tricladida, Dugesiidae) = Estudi dels processos que modelen la diversitat genètica en les planàries d'aigua dolça (Platyhelminthes, Tricladida, Dugesiidae)
The main goal of the present thesis has been to shed light into the processes that shape the genetic diversity of organisms, focussing in the following factors: the type of reproduction, the morphological diversity of ...
Understanding the regulation of leaf and plant gas Exchange under water stress with a process-based model of stomatal conductance
Water availability is one of the biggest constraints limiting the plant growth and species distribution around the world. This is the case in the Mediterranean region where, moreover, the frequency and amount of rainfall ...
Understanding the role of body weight and composition on lung function growth and decline
Background: There is evidence suggesting that body weight is associated with lung function, but results are contradictory and suffer from important limitations. We aimed to assess the association of body weight and composition ...
Understanding the role of iron homeostasis in rice immunity and novel applications of miRNAs for crop protection
Les plantes s’enfronten constantment a una àmplia gamma d’estressos ambientals que provoquen importants pèrdues en els cultius. Aquests estressos es classifiquen, segons la seva naturalesa, en estressos biòtics o abiòtics. ...
Understanding the role of polyglutamylation in the mitotic spindle
To ensure faithful segregation of the genetic material, cells build the mitotic spindle, a machinery made of dynamic microtubules (MTs) and MT associated proteins (MAPs). Chromosome bi-orientation is achieved through the ...
