(Institut Català de Nanociència i Nanotecnologia)
Controlling thermal energy transfer at the nanoscale and thermal properties has become critically important in many applications since it often limits device performance. In this study, the effects on thermal conductivity arising from the nanoscale structure of free-standing nanocrystalline silicon films and the increasing surface-to-volume ratio when fabricated into suspended optomechanical nanobeams are studied.

35 p, 437.3 KB Cartesian echoes in Kant's philosophy of nature / Massimi, Michela (University of Edinburgh. School of Philosophy, Psychology and Language Sciences) ; De Bianchi, Silvia (University of Rome "La Sapienza")
In this paper, we take the cue from a recent observation of Dan Warren about pre-Newtonian elements in Kant's philosophy of nature to argue that there are two puzzles concerning Kant's claim that mechanical laws presuppose dynamical laws in Chapter Three of Metaphysical Foundations of Natural Science. [...]

126 p, 726.2 KB Transport equations via smooth kernels / Cantero Guardeño, Juan Carlos ; Orobitg i Huguet, Joan, dir. ; Universitat Autònoma de Barcelona. Departament de Matemàtiques
En aquesta tesi estudiem l'equació del transport no lineal i no local. Aquesta equació en derivades parcials descriu l'evolució d'un escalar que es transporta seguint un camp de velocitats. El camp i l'escalar estan relacionats mitjançant la convolució d'aquest últim amb un nucli escollit. [...]

In this thesis we study the non-linear non-local transport equation. This partial differential equation describes the evolution of a scalar which is transported by a velocity field. The field and the scalar are related through the convolution of the latter with a chosen kernel. [...]

18 p, 3.4 MB How to Choose a Shunt for Patients with Normal Pressure Hydrocephalus : A Short Guide to Selecting the Best Shunt Assembly / Sahuquillo Barris, Juan (Universitat Autònoma de Barcelona. Departament de Cirurgia) ; Rosas, Katiuska (Hospital Universitari Vall d'Hebron. Institut de Recerca) ; Calvo, Helena (Hospital Universitari Vall d'Hebron) ; Alcina, Aloma (Hospital Universitari Vall d'Hebron) ; Gándara, Dario F. (Hospital Universitari Vall d'Hebron.

Most patients with hydrocephalus are still managed with the implantation of a cerebrospinal fluid (CSF) shunt in which the CSF flow is regulated by a differential-pressure valve (DPV). Our aim in this review is to discuss some basic concepts in fluid mechanics that are frequently ignored but that should be understood by neurosurgeons to enable them to choose the most adequate shunt for each patient.

Background: Tissue hypoxia-reoxygenation characterizes obstructive sleep apnea (OSA), a very prevalent respiratory disease associated with increased cardiovascular morbidity and mortality. Experimental studies indicate that intermittent hypoxia (IH) mimicking OSA induces oxidative stress and inflammation in heart tissue at the cell and molecular levels. [...]
