Obesity constitutes a problem whose manifestations have consequences in almost every field of the medicine and nowadays there is a lack of pharmacological therapy alternatives for its long term treatment. Lipidic compounds ...
Paetzold, Bernhard (Date of defense: 2013-12-02)
M. pneumoniae is one of the smallest self-replicating organisms. Many organism wide studies have been performed on M. pneumoniae and provide a wealth of information on the bacteria. However, the genetic tools to manipulate ...
Nur, Kamruddin Md. (Date of defense: 2016-01-11)
In this thesis, two approaches of information presentation on indoor view have been presented using Radio-Frequency Identification (RFID) and camera sensors on a robot. The goal is to capture images of the indoor environment ...
Mungara, Ratheesh Kumar (Date of defense: 2016-12-01)
Spatial frequency reuse is a long-established approach for enhancing the capacity of wireless systems through increased spectral efficiency (bits per second per unit bandwidth). The future 5th generation of wireless systems ...
Krüger, Angela (Date of defense: 2012-12-14)
The embryo of Caenorhabditis elegans is a model system in which development can be studied at single cell resolution. In this thesis I describe the use of a semi-automatic nuclear tracking algorithm to analyze cellular ...
Tejedor Vaquero, Juan Ramón (Date of defense: 2014-06-11)
Alternative splicing is an essential regulatory layer of gene expression that expands the coding potential of the genome in multicellular organisms. The spliceosome -the sophisticated machinery involved in intron removal- ...
Romão, Daniela (Date of defense: 2021-09-10)
Alterations in developmental transitions are common among animals to compensate for growth disturbances. These variations are usually a consequence of altered steroidal hormone production resulting in puberty delays. ...
Hans, Christina (Date of defense: 2017-09-26)
This thesis investigates various aspects of systemic risk in nancial networks. Chapter 1 explores the existence of a contagion channel to security returns given that banks are connected via overlapping portfolios. Making ...

Carvalho, Tiago Loureiro de (Date of defense: 2016-01-21)
Genetic variation in humans and the great apes has been amply explored using a wide variety of markers, among them tandem repeats (TRs). Because of the nature of TRs, highly variable in length due to its high mutation rate, ...
Ashok, Anupama (Date of defense: 2019-01-21)
COPII vesicles of 60-90nm diameter are known to export secretory cargoes from endoplasmic reticulum (ER). However, they cannot be employed to export bulky cargoes like the collagens that can reach up to 400 nm in length. ...
